Back on the road. Take 3, or is it 4 now?
I've mounted my CellLogs further from the trunk lid. Hopefully this will keep the heat down and reduce my chances of further electronic glitches from. I'm still thinking this was the case of the failure, but don't have any proof without being there.

Battery Failure
I had lost a cell. It had expanded upwards! Here are some more pictures after I had removed it from the car.

Battery load testing
I'm frequently getting low voltage alerts (<2.5v) while driving and was curious how many cells were meeting this criteria. First I'll recheck the torque on the batteries, but assuming thtat is fine, it looks like I can replace the one cell and fix this. My normal driving never reaches 3C range unless I'm really needing to pass somebody. Replacing this one cell should remove the low voltage alerts most of the time. I have an extra cell sitting around that I've tested at 160Ah capacity. I'll replace cell 5 with it and hope the voltage sag on it is closer to the averages seen here.

Heatsink replaced
I got some time yesterday and installed a new heat sink that I think will be more efficient while driving. I mentioned before the old heat sink below has the fins parallel with the controller, but the air while driving is perpendicular to the fins.

This is cool!
Now that I'm driving to work again, and the heat is coming, I figured it was time to rebuild the AC system. There was quite a bit of machine work needed, so luckily my uncle Duane had some time yesterday. The main pulley was bored out to 7/8" and a new key way made. A thin bushing was made that went on the shaft first. This slid to the furthest inward point on the shaft and allowed us to tighten against that and not allow anything to slowly walk in and rub on the housing. Next, I reinstalled the Netgain RPM sensor and finally the main pulley went back on. A 3/8" bolt, custom washer, and some Loctite then went on to keep everything in place. The mounting brackets base had to be cut and slid outwards about 1/4" to account for the new position of the main pulley.
Here are some pictures of the final system. You can see I reused the auto tension pulley from the original serpentine belt system. I reused the same belt I purchased the first time I did the AC. Luckily it was still the right length even after the positioning of the components shifted a bit.

Back to work
Air Conditioning:
The weather is going to start heating up. Later this week I have plans to meet up with my uncle and get some machine work done. Afterwards, I can rebuild the brackets to mount the compressor and I should have a comfortable commute home in the afternoon. I'll post some pictures of the AC system when completed.

My worst cell
I drove 65 miles and brought it home using 137 Ah. At this point my check engine light was coming up with only about 1C draw so I new at least one cell was getting low. I saw that my voltages were fairly well scattered around which was expected considering how scattered the self discharge seems to be.
Below are the photos of each cells voltage starting from the back of the car and working forward. There is one cell at 2.7v. This cell is basically dead and my worst cell. I'll probably yank or replace at least it. I have two more cells at 2.9 which means there is maybe another 5Ah in them tops. Most of the remainder of the pack is around 3.1. I'm guessing there is at most 10Ah in these cells. On the last two pictures you'll see sequentially 10 cells which are all 3.25v. These are the additional cells I added about 1.5 years go which have almost no miles on them compared to the others. They are still happy and have at least 20-25Ah left in them I'm guessing.
So this means that my worst cell is still giving me just over 85% capacity after four years. If I hadn't over charged some cells slightly, and over discharged multiple times, and never went over the 3C rating, I would be a bit upset. Considering the abuse I'm guessing this is right on par with what's to be expected.
So now I'm debating what to do. Ultimately I'm thinking I'd like to go with a much higher pack, say 350v using 100Ah CALB cells. These cells are now rated at 4-5C with 10 second bursts of 8C! This would require multiple changes. First and obviously the pack needs to be completely replaced which isn't cheap. Second the motor controller would need to be replaced with something like the Netgain or Soliton1 which allows high input voltage but you can regulate the motor side voltage to keep it safe. This also equates to even lower cell side amperage draws which should be easier on the cells. I'd also need to replace the charger. No hard feeling here though. The Thundersky charger is twice the size of say the Manzanita Micro charger for the same output (did I mention is weighs twice as much too?).
My other thought is to slowly replace the TS 160Ah cells as they wear out with CALB 180Ah cells. Physically they are identical so no mods would be required. These cells are also 4-5C rated so they can handle the amps my modified Curtis is demanding. I've got some thinking to do.
Either way, before I get back on the road any time soon, the AC needs to be redone. I'll need to engineer the mounting bracket (again) and machine some parts for the pulley. It's a shame it wasn't a direct bolt on replacement from the ADC 9".
It's suppose to cool off next week, so despite no AC, I think I'll drive it to work and see how the batteries hold up before investing any further time.

Too much voltage, a new motor, and self discharge.
While driving though I did figure out the cutting out issue I'd been seeing. It was not the motor but the controller itself. It was switching frequencies and making a terrible jerking affect. My friend has now modifed the controller to remove this feature.
The car was done for quite awhile and then not driven at all the last year which led to another interesting discovery. Remember that I dropped all balancing boards to experiment to see the real need for this. Every 3 months or so I'd go out and plug the car back in to charge. Now, after a year I was getting ready to take it on a long drive and notice one cell was very low 3.1v resting. I charged the pack but only to replace about 20Ah in the pack. I then charged the one cell to find it took an additional 60Ah! My first thought was this cell is bad but it turns out most of pack was VERY unbalanced just from the self discharge. Each cell was different taking another 20-60Ah compared, I guess, to some of the better cells that didn't self discharge so bad. I'm in the process of replacing the balancers and getting the pack balanced again. I then plan to do another capacity test on this pack and see what shape it's in. I'm hoping to start driving it to work again when weather permits.

Back on the road
The original BMS didn't have any wire protection, if for some reason a wire got shorted out and burned up, you'd have to rerun that wire. I added small inline fuses to each cell at the battery. It's a little more cost and time, but something that's worth it in my opinion.
Here is a picture of the completed front end. Six batteries were removed from the original design to all for the AC compressor and pulley assembly. The good news is I finally have AC, but the news is it's winter time and I have to wait awhile to use it. However, part of this was to add the heater and on the cold mornings it really heats up the small cab space of this car quickly.
The motor controller was modified in multiple ways. First the Curtis "whine" was removed and the car is now completely silent, as an electric car should be. The maximum voltage was increased to allow for my fully charged voltage on 54 cells (I charge up to about 184v). Finally the amps was increased from 500 to 750. This made a huge difference in acceleration and overall power. My 0-30 went from (I think it was 7 seconds) down to less than 4 seconds. Overall the total power of the controller went from 72kW to just over 130kW.
I removed that large, and unreliable BMS screen from the dash and replaced it with the E-xpert Pro. This has turned out to be a great little display. On top of showing pack voltage, amps, Ah, and remaining runtime, it has some other extras and is highly configurable. You can customize this meter to your battery, driving needs and how hard you want to push your battery by setting what is considered full, empty, when to raise alarms, etc. So for example I setup mine to alert me when the pack is 30% SOC and to consider 20% SOC empty. This affects how the "fuel" gauge displays its bars. I also turned on a feature that will automatically add the back light as long as >1 amp is going through the shunt. As I drive the back light is on, and 10 seconds or so after stopping it turns off. I also configured the meter to consider the battery full when 184v is reached and the charger is at about 2 amps for at least 1 minute. This then resets the Ah counters and gauge and avoids any calibration errors that might allow the meter to slowly drift over time.
Here is the trunk now. I wouldn't call it finished because things are still a little messy and I'd like to get carpet back in there. Trunk space is still reduce, but I can at least fit something in there now if needed. The little black things on top of the charger are the new Cell Log 8 modules that I'm using to monitor high and low voltage conditions. These are about $13 a piece and will monitor 8 cells each. I build a little circuit board for each to simplify the wiring. They have an internal relay that allows you to provide signalling to the charger, a buzzer, light, etc. They are not isolated, however, so expect to use an additional relay on each module to isolate it. These modules will turn on when the charger is connected to AC power or the key is on.
Another thing I modified this round was the suspension. I added another 9 cells (over 100 lbs) and with so much additional weight in the rear I knew I couldn't avoid it this time. Online I found the spring rates saw that the rear springs were much stiffer than the front. The front springs were 245 lbs/in while the rear springs were 311 lbs/in. I moved the rear springs to the front of the car and replaced the rear with 10" (original springs are 11" unbound) 400 lbs/in springs. The put the rear exactly back to stock ride height and my front is still 1/4" lower but I think within range for alignment. I still need to take the car back down for an alignment to see if this will do.
It's great finally being back on the road. The gas to drive my truck 70 miles to work each day was really adding up. That and I just missed my car, too much fun to drive. I'll keep you posted on miles. I think around 16-17k miles total at this point.

Trunk Ventilation
I plan to ensure adequate ventilation this time and have installed two 120mm fans. They will connect directly to the 240v charger source and run continuously during the charge cycle. The fans are quiet (30 dB), low speed (1900 RPM), move up to 67 CFM and take 7.5 watts of power each.
Here is a shot of the mounted fan. The trunk is big ugly at the moment but I plan to reinstall the carpeting after the modifications are complete.
Here is a shot from the bottom of the trunk. I've installed a vent which will deflect water spray while driving. They are angled to take the incoming air which should close the vents as well during speed.

Motor Cooling
My plan is to install four small fans directly above each set of brushes that turn on when the motor heats up using a thermostat. The thermostat is basically a temperature driven switch that will trigger a relay to turn on the fans. I selected 40C or 105F as the turn on. This will keep it from turning on during short trips but will ensure it starts cooling as soon as possible.
Here are the fans I used. They are 2" fans that do 20 CFM and draw .25 amps.
Here is one of the mounted fans and the thermostat. I made a bracket that attaches to the old temperature sensor and the thermostat bolts to the bracket.
When I manually enable the system I can feel a good breeze coming out the back the motor so that's a good sign. We'll see what happens after I get it back on the road.

More battery testing
When I got the original cells I was told the factory capacity tests were all above 160, if I recall they were mostly around 165Ah. I charged a group of four new cells the same way I did the old cells. That is, not long after switching from CC stage into CV stage I remove charge and begin testing. The old cells were drained at ~130 amps until 2.5v and the worst cells yielded 145Ah, most around 150Ah. The new cells I only drained down to 2.8v and the reason is that at 2.8v they had produced 183.5Ah!
This raised a few thoughts of course and along with the fact they have improved the cells, I'm lead to believe that Sky Energy (CALB) who sells an equal size and weight 180Ah cell for more money is most likely selling the exact same battery. Unfortunately I don't have the 180Ah cells to test, perhaps they are getting 190-200Ah. I believe the batteries might be coming with more capacity also so that after time, they are still considered to be at their rated capacity or higher.
Trunk Mods Part II

Too Cool
The first and probably hardest step determining how power the compressor. My first option was to modify the compressor to use a standard V belt. In this case it was easy to create a main pulley to attach to the motor. However I determined, after dismantling the compressor, it was going to be very difficult. My second option was to find/make a pulley that could use the same style of serpentine belt the compressor used. I opted for this method. I used the original pulley which accepted a spline shaft. The ADC 9" motor has a much smaller, round keyed shaft. I bought a 3/4" hub from tractor supply. I was able to get my uncle to turn down the hub and we then pressed it inside the original pulley with a hydraulic press. We ran a weld around one end to make sure it could turn inside. With this done it was just a matter of fabricating a frame that mounted the compressor and tensioner to the motor frame.
Here you can see completed setup. Reusing the tensioner instead of trying to make the compressor adjustable is the best route. The tensioner keeps the belt at the ideal tension as it stretches with age. This setup should be maintenance free for years.
Here is a shot from the other side.
I ordered from Jegs and got a Gates belt K060345. This is actually a bit over 35" and is the six v serpentine style belt used originally, just much shorter. This was stocked and I got a "free" hat. Considering their "free" shipping had a $5 handling fee, I'm not sure which one of the two I actually got free.
Here is a 12v functional test video. It's not nearly as noisy as this little camera picks up.
After everything was functional I needed to charge the AC system. The system had been opened for months, and even if it had only been opened for a day or so you need to do a lengthy evac process. An oil based vacuum pump is required which I bought one from Harbor Freight. You'll also need an AC manifold set which I also got from Harbor Freight.
The process is fairly simple. First connect the high(red) and low(blue) side hoses to the A/C system. The sizes are different so you can't accidentally connect the wrong one. This manifold set has a yellow hose and two spots where the yellow hose can connect, one is open and the other is a pressure fitting. Connect the yellow hose to the open side and then to the vacuum pump. Turn on the vacuum pump and then open the high and low valves. Let this run for several hours, the longer the better. The pump will get the system down fairly quickly, but it won't remove all the moisture this fast. You must leave it running to remove the moisture (3-5 hrs will do it). Once complete, first close the high and low valves, then turn off the vacuum pump.
You'll need to check the service manual to determine how much refrigerant should go into the system. You'll also need to replace any oil that was lost. There are refrigerants that contain oil, but it's not enough for a complete recharge so you'll need to do the math and figure out what you need.
The recharge process is simple. Read and follow the directions on the can first and foremost. Disconnect the vacuum pump and connect your refrigerant. The can should be shaken during the entire process. Open the valve on the can, then open the LOW side ONLY. Never open the high side valve while recharging. You'll hold the can upright and rotate 90 degrees every few seconds again given the can a good shake frequently. You'll want to make sure there is enough refrigerant and oil in the system before turning on the A/C system (again consult your service manual). Most systems should have a low pressure safety switch to prevent this. With the A/C system on max you'll notice the low side gauge drop as it compresses the gas to the high side. As it pulls from the low side more refrigerant from the can will pass into the system. As the can empties it slows down so be patient 5-15 minutes per can. Repeat this process to add oil and more refrigerant as needed. When complete close the low side valve, then close the refrigerant valve. The high and low side connectors can be popped off easily at this point, but when you disassemble the manifold some gases will escape so do this in a well ventilated area so you don't breath it in.
That was it, now I have some really cold air coming out of my EV!

Trunk Modifications Part I
- Greater range. More cells means I have more energy and can travel further before recharging.
- Distributed load. The more cells I have, the less they have to work for my daily commute which will increase the life of the cells.
- Performance. Currently the 144v system allows the motor to hit about 4k RPM before the controller switches to VMax. Any additional increase in RPM greatly reduces torque requiring you to shift to a higher gear. Increasing the voltage will allow the torque to remain steady for higher RPM meaning the motor will want to rev out higher.
Here is a shot of the original trunk space. You can see there isn't much usable space currently above the fuel tank, about 3" and it opens up to only about 8-10" on the far right.
The old spot I use to have the charger has a curve to it and greatly reduces the usable space.

Battery testing
Below is my battery testing solution.
- Costco a 2300 watt power inverter. This allows me to test four batteries at a time to get my 12v source.
- 1500 watt space heater. This gives me just over 130 amp load on the batteries which is close to 1C and will give a decent enough load to test.
- E-Xpert pro battery monitor from TBS Electronics with a 500 amp shunt. This will track the Ah used for me and give accurate results compared to trying to calculate this myself based off of ever changing voltage/amperage as the batteries drain.
- CellLog8 allowed me to easily monitor each cells voltage to determine when a cell was too low during the load test or too high during recharge.
- For charging I used my original battery charger, a 12v charger I had, and my bench power supply. This allowed me to charge up to 45 amps and helped speed up the testing greatly. I only did quick charges and once the amperage needed was between 5-10 amps I stopped charging and begin the test. This means the cells were NOT fully charged (probably 90 - 95% is my guesstimate) which is important when reviewing the results below.
My original testing plan was going to be to drain the batteries until the first cell reached low voltage, then rotate in another cell and continue testing to get results for each cell. After doing this only once I realized that the capacity of the cells was extremely close and it wasn't worth the extra time. I won't post all the results but basically my lowest cell produced 145Ah. I had other groups producing 148, 150, etc. They were all extremely close. Even the two cells that have terrible voltage sag still produced over 145Ah like the others. Now 145Ah is just over 90% of original capacity, however, remember my charging method was manual and I didn't give it the time to do much constant voltage charging. So to my surprise, I think I'm still near original capacity. The only thing is I didn't do this testing when the cells were new and I'm told they will have at least 160 but usually more, so it's possible I've lost more than I know. Either way this is good news and I'm quite happy with the results.

In the name of science part II
I've been in touch with a great guy who works at Curtis. This weekend I had the opportunity to test a modified Curtis 1231C. Unfortunately I only had a 500 amp shunt so we weren't able to test the motor side amps. I did see my battery amps peaking somewhere around 650-700 though as the controller reached Vmax. This controller reduced my 0-30 to 5 seconds. I will add the shunt later and get the real output from it soon.
He also has an even higher end modified 1231C, but we were having some issues with it. It should be 200 amps more or so. It would be nice to see a 3 second 0-30 :)
Unfortunately I can't give out any of the secret sauce that is being used to upgrade/modify these controllers since I didn't obtain the information myself and don't want to get anybody in trouble.
We should be doing some more tests with the 2nd upgraded controller later and I'll be sure to have the shunt ready for some numbers. I realize most people won't be able to make these modifications, but it should give you a good idea of expected acceleration for a given amount of continuous amps.
Tuesday, June 22, 2010
The increase in temperature has made a little improvement to the increasing voltage sag. I think the bottom line is I'm pushing these cells harder than I should for longevity. I believe my commute to work is using >80% capacity and this is taking a toll on capacity. Some mornings I have cell that is very close to fully discharged. I don't know how many miles I have left before at least one cell can't make it and possibly gets ruined to get me here.
I keep going in circles, but I'm leaning towards not selling it now. I'm thinking of making some modifications though now that I see how reliable the conversion itself is. Nothing official yet but here are some ideas I'm toying around with.
Motor controller: The Curtis 1231C has been reliable but I want to get the acceleration back in this car. I'm leaning towards the Soliton1 again for a few reasons.
- It will increase my motor side amps from 500 to 1000.
- It's much larger and has great cooling with the option of water cooling if needed. In the hot summer days on my long commute doing 70mph the Curtis is kicking down the amps sometimes.
- It has many features that will make protecting the batteries, and motor a breeze. I'd like to add some features, but reduce complexity of the build and I think this will be a good step in that direction.
- I'll have the ability to run a pack voltage that is much higher than the voltage applied to the motor. This allows you to run more smaller batteries allowing you to still get the capacity you want, but make it easier to fit them. It also will remove volt sag during hard acceleration. The pack itself will sag, but if your pack voltage is high enough the motor will receive a steady voltage increasing performance even on those cold days.
Trunk mod:
I think I'll end up cutting out the current trunk and expanding it. There is a LOT of room that is not being utilized under there. This will allow me to add more batteries and even move some of the front batteries to the back giving me room to finally mount that AC that I've been missing.
Currently I'll just add some more cells (I'd like to add another 15 or so) so I can get as much from the existing cells. This should ease up on them and extend there life some on my commute. This will give me not only more capacity but the ability to crank up the motor voltage a bit also to increase high end performance along side of the low end performance I'll gain from the controller change.
I'd like to get the car to a point where I don't have to look at anything and worry about what's going on. I want to simplify this side of things most of all. I want to be able to get in the car, look at my "fuel" gauge and know if I'm good to go. If there are any issues, then be able to connect something and diagnose the problem. I'm looking into some options for a low cost over haul here. The biggest problem with adding more and more cells is the complexity of protecting them.
As always, anything I do I'll document and share with you.

One year
I decided to do some quick math to see what 12k EV miles really means. The car originally got 26mpg on my commute. 12,000 miles/26 mpg = 461.5 gallons that I didn't burn this year. Gas in my area has been more or less $3 over the last year so that's $1384 dollars I would have spent on gas.
Although it's great to not have given my money to the oil companies or burned the gas, the actual conversion cost vs returns would never pay off before something needs to be replaced (i.e. batteries). EVs of some form are definitely the future, now we just need to wait for all the auto manufactures to get those production models out which will reduce costs. 2011/2012 will be a huge turn for the auto industry...I can't wait!

10k miles and counting
You may recall I reported two cells which sagged considerably more than the rest. I figured these would have went out by now but they are still working fine. On the down side, I now have two more cells that seem to sag more than before (about 0.4v under 2C load lower than the rest). I don't plan to replace any of them until they go out completely so I can really test them out. Speaking of replacing them, I noticed that Elite Power Solutions has finally dropped their prices to be more competitive with some of the other suppliers. We'll hopefully see a continuing trend making this option more affordable for all.

When to short is two long
The cell was directly shorted out for a good two seconds, maybe a bit more, although it seemed liked a minute as I was jumping around trying to stop it. :)
I gave the cell a separate charge knowing I had discharged it quite a bit and definitely exceeded the maximum discharge amperage. Somewhere during the first or second week of driving to work the cell didn't have enough capacity to make it here and dropped to zero volts. I knew I had done some damage to it now, not from the zero volt, but the fact that it reached zero volts. If you recall, I've taken another cell to zero volts and it's still alive and kicking so no final verdict there yet.
I manually charged this cell up again for about a day at 5 amps, AFTER the pack itself had reached full charge. This one cell, however, would never fully charge. It seemed it internally had a self discharge of a couple amps maybe.
However, it continued to get me to work...until today. The cell reached zero volts again on the way to work and I knew it was time to replace it. This time, the cell would not charge...at all. I could not get the voltage above 0.7v and the cell got very warm when charging.
So although this is the extreme case of discharging at high rates, it may speak slightly to what happens to a cell when exceeding the maximum continuous ratings, just to a lesser degree. In short, it's bad :)
So, I've now lost my first cell. Luckily it was due to my own ignorance and not a failure for general use.
On a side note, I have noticed much greater voltage sag with the colder weather under load. This may be because the cells don't charge as much in this weather as well as the temperature it self during operation. It's about 45-50F when I leave in the morning and the car charges outside. We'll see how bad it gets when winter really kicks in here.

5000+ miles
In short, that's pretty much what needed to be done to the car, nothing. I did raise the vehicle and get under there for an inspection. I wanted to make sure no bolts were missing or coming loose. Additionally I wanted to check for stress or crack marks in the motor mounts, batter racks, etc, but everything looked perfect.
I'm actually over 6k miles at this point. Roughly I think I have about 100 cycles on the batteries after the 4 months of driving @ 1.25 cycles per commute round trip. This is a pretty rough number, but good enough for general tracking of the cells life over the months and years to come.

As bad as it gets, or is it?
A few weeks I was driving to work and looked down at the TS BMS system for kWh. The reading was FAR lower than normal for being halfway to work. My first though was, "crap it didn't charge and I'm halfway between home and work". I decided to keep going and keep light on the throttle. I made it to work with power to spare. It turned out the pack was completely charged when I left home, but the BMS failed to recognize most of the energy that was charged into the pack.
The Post:
It's been about a week ago, and I was just pulling out from work to head home. I noticed the computer again didn't register that it had charged. I assumed it was an error and headed home. Sadly this time it wasn't a false alarm. I drove about 32 of my 35 mile trip home when the BMS started yelling about a low cell. Even more sadly, this didn't alarm me since the computer is always giving me false positives. Regardless I started watching the cells and noticed all of them were a bit low (2.8v on average) with the lowest one being 2.5v or so. As I continued to drive they all started dropping, but one more so than others. I could see it going 2.5, maybe 5 seconds goes by, 2.4v, etc. It didn't take any time to reach zero volts under load. At this point I figured I've lost a cell, but the other were still in the safe zone.
I got home and after turning my charger amps down to 2 began charging. It took a few hours until the cell was up to 2.8v and I cranked it back up to 30 amps and let it charge.
The next day I was hesitant to even try to make it to work, but I figured this is half the fun of owning an EV. I was surprised to find out that not only did I make it to work but that cell was in the top 5 or so under load meaning the internal resistance was not changed and it's still behaving pre-incident.
How much life, if any has been taken away from this cell? No clue and only time will tell if fails before the others. However, and most importantly, this shows these cells are able to take a lot more abuse than I figured.

Solar and PG&E (Pacific Gas & Electric)
The solar is directly connected to the grid through the inverter. The inverter is designed to not send power into the grid if the electricty is off. This prevents the power company from getting shocked if they shut down their side and want to be sure no solar systems are now powering those lines.
So the way it works here is the power company keeps track of the excess energy you produce during the day. This is done in the simplest terms by letting your meter run backwards. Then at night, lets say, when you're not generating any power your meter runs forward again and you recover that excess energy you created earlier. It's really a great setup since you don't have to worry about costly batteries that need replacing.
Additionally, and to some what complicate what I just said, we have a couple of options here and I went with a time of day (TOD) metering. Peak is 1pm-7pm, partial peak is 7-9pm and 9am-12pm, off peak is 9pm - 9am. This is Monday through Friday. The weekends don't have peaks and all holidays are also like weekends. For peak the energy rates start at about 30 cents per killawatt. Partial peak is about 14.5 cents, and off peak is 8.5 cents. What this means is while I'm at work and not using much energy not only am I making excess energy, but it's not really counted on the kW basis. It's tracked as credits in the form of currency. Later at night when I get home and start using the power again I'm buying it back at a cheaper rate than I sold it for. This helps out the power company to supply their power needs during the "peak" for all users and allows me to only require a system that generates about 75% of my energy use.
It gets more confusing yet...Each Peak, Partial Peak, and Off Peak have their own seperate tiers. Tiers, for those who don't aleady have to deal with this, is an alloted amount of energy you can use at a set price. Once you use more than this the price of the power increases. I believe for my power company their are 5 tiers. So even with the right sized system you might end up going up in tiers during off peak (night time and weekends) simply because you don't generate much here. However, you've also been getting paid quite a bit during peak to cover multiple tier pricing during off peak.
So that's how it all works for me with my power company. Hope this clears things up, I know it confuses me more. :)

Elite Power Solutions - Not so Elite
As you're aware for those following along I've had a few, to say the least, issues with the BMS system I purchased from Elite Power Solutions. I've emailed them quite a few times along the way but never really got a fix to anything and it always resulted in me figuring out a work around to make the system happy.
Recently, I thought I had two bad cells. It turns out, again, the BMS was misreporting these cell voltages, but only under load (they show fine at standing voltage, but drop quicker in voltage on under load than they really are). Here is the email transaction. It seems to start off fine, but after well over a month, I just feel like I'm getting the run around.
EDIT (Emails Removed):
Turns out the emails sent around clearly stated they were not allowed to be posted anywhere for public view. I was nicely asked to remove these emails from my blog.
This is where it's at now. I'm sure they will not get back to me until I bug them again. They are more than happy to take your order, but don't count on that one year warranty being honored. As far as the TS cells themselves, I'm so far quite pleased. I only ordered them from somebody in the US hoping to get the customer service support if needed.
I'm probably screwed on ever getting this thing fixed and might just design my own or mix and match a few other options out there.
So where should you buy these cells from now? Dave over at EVComponents is offering the cells and a different charger and BMS system. I kick myself, because his cell prices are about 70% of what I paid from EPS. Check out his website at http://www.evcomponents.com/. They are working at keeping these cells in stock! This means no more 2-3 month turn arouund times either. Very promising for the EV world.
Update: Elite is sending yet another module out to replace the defective one. Sadly, I've discovered another issue with another module. This module has a problem with one cell where it will randomly cut the voltage in half (display only, the cell is fine). This in turn is telling the charger, if charging, there is a low voltage condition. To the charger this means terminiate immediately and do not restart. I've been lucky on the timing and so far have not been stranded while I was debugging the issue. I've since reduced my low voltage trigger to just above zero to prevent yet more false alarms. I'll keep you posted on the results of the second module replacement as well.

DMV trip four
As you recall from trips two and three, I was told to come back when the registration was due. This would allow them to open the smog section in their computers so they could input the DMV ID number on the BAR cert and finally change the MP field from G to E.
Well, as I'm sure you can guess, the smog section still couldn't come up. They tried this and that, talking amongst themselves and about 30 minutes later...nothing. So the lady says, "Well your registration is due, would you like to pay and maybe that will open up the smog section?" What do I have to loose, I'm thinking. I pay and the computer spits out the new registration paperwork. Sure enough, the MP section is already set to E!
So, in hind sight I'm thinking their system has changed a bit. The BAR referee computer must now directly change type to avoid the whole DMV confusion process. I think if I would have waited for the due notice to come in the mail, I could have paid it online and received the updated E registration without any of the headaches I went through.
I have had a few people telling me that E means something else, or doesn't exist, etc. So I'm really not 100% sure if this is done, and won't know for two years when the smog would be due again. I think I'm good, but you never know with DMV. :)

2500 and counting
OK, so there is one item I'm not completely happy with. The BMS from TS has some really great features all wrapped into one system. Many piece together things like amp meter, fuel gauge, etc. It was nice to find it all in one package, but this thing has been far from reliable.
You may recall my initial problems with charging where the BMS would freak out and start reporting cells at low voltages and such if the charger was at high amps.
The next thing I noticed was two cells that seemed to be sagging pretty bad under load. I placed a volt meter on them and they weren't sagging at all like the BMS reported. There are 5 modules, up to 10 cells connect to each. I switched around two of the modules and then I started getting two different cells (same module) that were reporting sag. I'm still waiting on a replacement from Elite Power Solutions. The first "replacement" didn't work at all and I had to send that one back.
I've also had a couple of occurrences where the charger just stops during the charge and I couldn't figure out why. I was at first assuming it was getting a little hot, so I started opening the trunk (until I get time to vent the trunk better). This seemed to fix it for a bit, but it started happening again. While driving the other day, the BMS alarm went off indicating one cell was about one volt lower than it really was (it immediately jumps back up to normal voltage). This has happened a couple of times now. During charging, any low voltage indication will terminate charging, so again the BMS shows its quality.
I have some plans to implement my own high and low voltage protection, and still use this BMS for the rest of it's functionality. This way if it blimps, it doesn't matter except for viewing purposes.

1.21 Gigawatts!
I kept climbing up on the roof when I'd get home from work to see what they had accomplished.
Here is a picture of some of the anchor bolts installed for one of the two groups of panels.
Here is a close-up of one. You see all the black caulking that goes into the drilled hole. Additionally the black piece of flashing will be over the bolt and hole with the higher shingle laid over this as well see later. This flashing allows most, if not all, of the water never even get near the hole.
Here is the south facing group of rails installed. You can now see how each anchor is covered by the flashing and slide under the higher shingle.

I thought of a fun little game!
I actually wanted some advice on what dress style would look good on me with my figure, but that felt like a self-centered thread, so I cooked up a little game to go with it.
The rules:
Post a pic of yourself to show off your figure. I recommend not posting pics in lingerie (internet dangers!), but rather in a comfortable form-hugging outfit so that you can see your figure clearly. Also state if you're insecure about something, what size you are and if you're tall or short (sometimes hard to see in a photo)
Then advise the bee (or bees, this is more fun so everyone gets more advise) above you on what type of dress you think would look well on that bee. Is she a typical mermaid bride? Would a ballgown look stunning on her? Do you think she would rock a strapless dress with her slim shoulders? Or do you think an empire fit looks best on her? Give her tips, it might help! We're no bridal consultants here, so I'd advise you still to do an actual fitting, but who knows.. You might get a tip regardig the dress fit and style from someone you hadn't thought of yet! Of course, actual dress suggestions with images are the best!Q

I'll start!
I'm a US 12/UK 14, relatively short (5.5 or 1.65) and I'm scared my hips and butt are too big! I also have a bit of a belly which I hate and am trying to lose! That's my problem area. I do like my waist though. I have a relatively long upper body and short legs
(think corgy)
I think a mermaid or fit&flare might rock my curves, but I'm also a afraid a ballgown might swallow me whole as I'm not too tall.
Any suggestions? I'll leave it open to you!

In order to build a cinder block fence, prepare a stable footing, outline the fence with snap chalk, mortar the first row of blocks and then continue to stack the blocks to the desired height. Smooth any excess mortar along the sides of the wall.
In order to build a cinder block fence, wear proper protective gear and use the following process.
- Review building codes
- Prepare the footing
- Assemble the first row
- Mortar the first row
- Build up
Before beginning the project, review all local building codes and obtain any necessary permits.
Dig a footing below the frost line and double the width of the cinder blocks. Fill any drainage lines with crushed rock and fill with concrete. Allow the concrete to dry fully before assembling the wall.
Snap a chalk line to follow for the first row of blocks. Then place the first row along the line, leaving a 3/8-inch gap between the blocks.
Mix the mortar with water until it reaches a consistency similar to frosting. Dampen the footing and apply a 1-inch thick layer of mortar under the blocks. Apply mortar to the sides of the blocks to fill the joints. Remove the excess mortar so it is flush with the blocks.
Place a 1-inch thick layer of mortar on top of the first row of blocks and stack the second row of blocks. Place the smooth side out for any end pieces that have been cut. Continue the process to the desired wall height. Trim and smooth the mortar around the surface of the wall to finish the job and allow to dry completely.

It occurred to me a few years ago that there was something fundamentally wrong with all forms of ism. Communism, socialism, capitalism all seemed to be different forms of colonialism whose only claim to greatness according to it's advocates was this decidedly chauvinistic claim that, for instance, Capitalism is good because Socialism is bad. Not much of a recommendation since all any of these did was promote a hierarchy of opportunists that game the system for their personal pleasure to the detriment of the vast majority of the people who like good herd animals willingly follow the latest strong man as long as he is packaged in the appropriate phraseology and images.
One of the latest crazes, a slight improvement over medieval feudalism, is Capitalism, generally an English invention that was spectacularly successful in launching the widespread exploration of the planet on tiny wooden sailing ships and then the industrial revolution. I will lump all forms of ism together with the name of capitalism for the remainder of this discussion since it is the only form of ism that really exists today despite what corporate propagandists would have you believe.
What made capitalism so successful in part was what started out as Lloyd's of London, a service that sent young boys as runners out to solicit subscribers to invest in different capital projects that would have been impossibly large for the English government to fund at the time. Although there were some short lived examples of large scale enterprises funded directly by the government in other European countries during this same period, it was the direct involvement by the middle class in these investments and direct participation in the rewards of these projects had a much more lasting effect, allowed for much more rapid and enduring growth and in fact those same financial markets have grown, become more complex, and drive the world economy today.
What was a novel way to finance large projects without interfering with traditional ways of feeding, clothing, and attending to the health, education, and welfare of the people has now been applied to every aspect of life much to the detriment of our economy as a whole and the ability to deliver high quality services as the corporate model of cost reduction has been applied to systems that have gotten far too large and complex to be sustainable in this kind of system. Strangely, what made the system so robust has come full circle to not being able to exist without the direct intervention of the government in every economic and public service sector. The economy has gotten to the point where it is no longer sustainable and the situation will continue to deteriorate until there is a paradigm shift into a new system beyond the current era of colonialism whose last and ultimate expression of capitalism is the corporate fascism and it's addiction to handouts by the government at taxpayer expense.
No system is perfect and people, being the adaptable creatures they are, will always find a way to manipulate the system to their advantage. After taking care of chickens for a few weeks I call this chicken behavior-they are always trying to steal food from each other and if one starts to bleed then the entire group will attack that chicken and peck it to death while they eat it's flesh. Nothing describes capitalism better than that in which every kind of opportunism is not only expected but encouraged. It took me a long time to come up with something that might replace fee for service capitalism but after discussing cooperative and community life with people from every economic sector I think that cooperatives and guilds are worth reviving and that they would work better than ever before especially with the communications technology available today. Guilds and cooperatives aren't new. They were a traditional method of doing business before the capitalization of the industrial revolution created a system of people that controlled the ability to create things people wanted and another class of consumers that were subordinated to service them. Described like that I don't discern any difference of the worst excesses of those two twins Communism and Capitalism.
I define guilds as professional organizations that produce goods or services. People that belong to guilds could negotiate with other guilds and cooperatives to receive compensation, services and goods. This isn't a radical departure from the way things work now, just more honest about describing the relationships. For instance, doctors currently decide how doctors are going to be trained, how many are trained, and even have a lot of influence over the cost of the training. The doctor industry has a virtual monopoly and have been the driving force in keeping fee for service medicine alive at all costs and preventing any reform for over 100 years that interfered with their ability to charge what they will with complete disregard for the efficacy of treatment or the cost to our economy.
The American Medical Association fought the establishment of Medicare in the 1960's but, since Medicare institutionalized the fee for service system in medicine, they have reversed course and now fight any attempt to change the way they are compensated preferring to pursue a corporate model of increasing revenues by providing as many goods and services as possible and always charging as much as the market can bear for each and every delivery whether it is a benefit to the receiver or not. In a system that is twice as expensive as the next most expensive country in the world on a per capita basis, that means that we are paying providers over a trillion dollars each year, in other words-more than the entire cost of the Iraq war every year, more than we should be for a high quality health care system. The cost to our economic development in other areas has been enormous. Instead of being the most progressive and well educated country on earth we are the largest debtor nation subject to theatrics and theft by our government with little to show for it.
Cooperatives can be operated by workers, producers, buyers, or even guilds. Typically members of cooperatives are owners. They can negotiate to buy or trade goods and services with others and participate in a democratic and equitable way with the proceeds. There really isn't any point in talking about all the different types of cooperatives because they are endless. The point of this is that we need to move beyond the quaint and inefficient separating and isolating individuals to promote the counting and accounting of money. The worth of individuals can be based more on their worth to their community, not their ability manipulate and compete with other in a system that disregards the needs of communities. We also need to move beyond this kind of compensation as the sole reason to do things that we all agree need to be done anyway.
People need to have housing, eat, receive healthcare and clothing. In order to maximize production and communication we need to have a robust education system, but not this factory model that is common today where we mostly produce cheap labor for corporations. Not providing those things or not giving everyone access to basic resources actually costs more than providing basic essentials if you assume that society at large will feel the effects of every sickness or disability in one way or another and really unless we are going to start culling what we see as the weak and disadvantaged from our society by various means of mass murder then we will be affected in a negative way for failing to care for everyone. What is happening now is more like a slow death for many people that are simply ignored if they can't be utilized as a profit center for an investor and we all pay the cost of deferred maintenance either directly or in the increased cost of goods and services.
By identifying the needs of groups of people in a system of guilds and cooperatives it is possible to have a much more honest discussion about how to meet the needs of individuals and to concentrate on the quality of enterprise as opposed to the cost or profit. We waste hundreds of billions of dollars a year regulating enterprise under our current colonial model and the larger the systems get the less able regulation is able to solve problems like the spread of infectious organisms in a highly distributed food supply. These complex systems are not just prone to failure. Failure is predictable and a sure thing as we have seen repeatedly. One of the things that we have learned from the local food movement that applies to all of our enterprises is the importance of knowing your farmer and the source either directly or through someone else that you trust. That lesson goes far beyond a discussion about the food supply. It is a metaphor about how business can be conducted in general.
When there are no community ties or the ties are known to be unreliable, as is the USDA and all of the schemes that Congress has been foisting on us in an attempt to rationalize a system that by it's nature will always defy any attempt to bring order, then the means does not exist and cannot be artificially created to replace community and personal communication back and forth and up and down the chain to ensure that the system is not only robust but that communication is timely. Trading between guilds and cooperatives limits the size and complexity to make a more open and safer society.

Of Scottish descent or just a fan? Then the Grandfather Mountain Highland Games are for you! Scheduled for July 7th through the 10th, 2016, the 61st annual return of The Grandfather Games promises three days of tartan plaids, food, music, and athletic prowess!
The annual Grandfather Mountain Highland Games and Gathering of Scottish Clans has been held on Grandfather Mountain, near Linville, NC, since 1956. Modeled after the several hundred year old tradition of the Braemar Games in Scotland, the Grandfather Mountain Highland Games have been called "the American Braemar."
North Carolina has been home to large population of Scottish people since 1746 when the Battle of Culloden left many Scottish clans with nowhere to live in their own country. When the government offered land and tax exemptions to these displaced Highland Scots, North Carolina became a sort of second Scottish homeland. A great many Scots people have called North Carolina their home ever since.
While a relatively small gathering in those early days, the Grandfather Mountain Highland Games now claim to be one of the largest gathering of Scottish clans in the world! Thousands of Scots and their friends gather at MacRae Meadows on Grandfather Mountain each summer to revel in the sound of bagpipes and kettledrums and to join in or enjoy watching the athletic competition of the games.
As it is one of the largest such gatherings, the Grandfather Mountain Highland Games attract serious athletes to their games, a septathlon of sorts that includes a hammer throw, weight toss, caber toss, sheaf toss, Highland wrestling, the kilted mile run, and a clan tug-o-war. There's also "The Bear," a grueling, 13 mile hill run up Grandfather Mountain – a 1,568-foot elevation change!
The Grandfather Mountain Highland Games also include other events and attractions, such as Piping and rumming competitions, dancing competitions, the Parade of Tartans, border collie sheepherding demonstrations, Celtic entertainment, and a popular open-air market with Gaelic food and gift items. You can even trace your Scottish roots to learn more about your Highland heritage – don't miss it!
The 2016 Grandfather Mountain Highland Games
July 7 – 10 – MacRae Meadows, Grandfather Mountain, NC

Whether she's donning a dress that doubles as a projector screen (like at the Grammys earlier this year) or hitting the stage looking perfectly coiffed in a cute outfit, Carrie Underwood is known for rocking some seriously show-stopping costumes on stage. She's also unafraid to wear some seriously high heels -- boots or otherwise. But she may think twice after what happened to her at a concert this week!
Carrie was on stage in Corpus Christi, Texas yesterday when she stepped on the long hem of an oversized shirt and ended up falling on stage! Not getting up right away, you could tell she may have fallen in a perilous position. As it turned out, she finished the song (yay!), but she did end up in a brace later! Eek!
Check out the Instagram vid a fan caught of the nasty spill ...
Ouch, huh?! Damn high heels! Thankfully, Carrie can laugh about what happened. She tweeted later, "Hey, remember that time in Corpus Christi when that girl busted her butt on stage? Oh wait, that was me! #5inchheels #klutz." She also tweeted a picture of her foot in a soft cast, writing, "Good news, it's not broken…AND I got some new footwear!" Aww!
Wow, have I been there! I took a tumble at my friend's wedding a couple of years ago due to almost 5-inchers, and my ankle has never been the same. Plus, they say once you sprain/roll it, you're more prone to reinjury. Ugh, no fun. And definitely the nail in the coffin of my 4"+ high heel-wearing days. Oh well -- I may be 4'11", but really don't believe they're worth hurting myself for.
Carrie, on the other hand, is a performer who I don't see getting away so easily with wearing FitFlops and Nikes all the time! Ha! Once her foot heals up, I'd guess she'll continue to rock sky-high spikes down the red carpet, on the concert stage, and everywhere inbetween. With that being the case, guess we can only hope her costumer makes a point to hem any way too long gowns or caftans!
What's your take on super-high heels? Have you ever injured yourself from wearing them?

For all of the strengths of OS X, two of the complaints recycled year after year are the aged filesystem, HFS+, with its lack of file integrity, and the file manager, the Finder. While replacing HFS+ remains out of our reach, an alternative to the Finder for day-to-day tasks has been achievable for some time. Enter "Commander One," a dual-pane file manager that seeks to fill in the holes that the Finder has famously left. Let's dig in and see what Commander One has to offer.

RE[2]: Double Commander

BTW it is free to use and have no limitation. Why this constant moaning about source openness ?
Well, the main page (http://www.ghisler.com/) says it is Shareware, not free. You can use it legally for 30 days, after that you are required to buy it. It is the good will of the programmer that he doesn't enforce this after 30 days.
As for open source question, at least it is a guarantee that the project may live after the author abandons it or sells it for whatever reasons. Plus, as DC itself uses open-source and cross-platform libraries, it can be (and is) ported to various OS-es. TC, as the author says, cannot (at least, not without a lot of work) be ported because of its heavy use of win API and components.

According to NBA sources, the Washington Wizards are one of several teams interested in trading for forward Josh Smith. Should the Wizards make an offer to the Atlanta Hawks for Smith?
I personally believe it would not be a wise decision for Washington to try and make a deal for the 27-year old. First off, Smith is an unrestricted free agent at the end of the season, which means there is a good chance another team, more specifically a contender, will sign him this summer. Not to mention, Washington has a 15-36 record and are ranked third last in the Eastern Conference standings. What purpose does it serve to acquire Smith?
There is a very slim chance the Wizards make a miraculous run for the third spot in the conference even with a half of a season remaining. If they had a better record and thought the playoffs were a realistic possibility I could understand why management would make the trade, but the postseason is not going to happen in Washington this year, so the deal would make zero sense.
The Wizards also have to extend point guard John Wall's contract sometime soon as all that is left on his deal is a $7.5 million team option for next season. It would be ludicrous for Washington to not extend Wall as he is clearly the future of the team and someone the organization must build around. Since the Wizards only average 15,878 fans per game, one of the worst attendance records in all of basketball, there is definitely no money in the budget to extend Wall while also re-signing Smith, if that were even an option at the end of the season.
Smith is having a fantastic season as usual as he is averaging 17.4 points, 8.6 rebounds, 4.1 assists, 2.1 blocks and 1.2 steals per game while shooting 46.0 percent from the field and 35.4 percent from beyond the arc. The eight-year veteran would clearly be a great addition to the team, and would make them a lot better in the future if he stuck around. However, Smith is most likely going to seek a maximum contract and while some team will pay it, the Wizards are certainly not one of them.
Let's just say after all of this, Washington still wants to test their luck and take a stab at Smith. The unfortunate part about it is that there are so many other teams in the running, such as the Milwaukee Bucks, that can offer much more for Smith then the Wizards can. If Atlanta is giving up one of their top players, they are going to make sure they get the proper compensation in return.

2010 Ford F-150 SVT Raptor: Crew Cab?
August 31, 2010
Uncamouflaged pictures of the crew cab prototype of the 2011 Ford F-150 Raptor have been floating around the Internet for a while.
You can see how it looks in the spy shot above.
As Ed mentioned in a previous post, he thinks a crew cab would be overkill.
What do you think, should we have waited and gotten a crew cab instead?

Can you say you've directly impacted over 40,000 lives? Lisa Moon can!
Tuesday, December 03, 2013
Today is International Day of Persons with Disabilities and Champions Career Centre is proud that our fearless leader Lisa Moon is a finalist for a Community Impact Award in Calgary. Whether she is officially awarded the prize this afternoon or not, there's no doubting her winning achievements and dedication. Here is Lisa's story.
In 2000, an innovative agency was established in Calgary. The first of its kind, Champions Career Centre was created as a PAN disability agency whose sole purpose was to focus on increasing employment of persons with disabilities.
The first person hired as a member of the Champions Career Centre team was Lisa Moon. Lisa came from a rich background that included working with programs for another underutilized group – youth. Lisa's experience in building systems, establishing effective processes, and strengthening relationships was the cornerstone of Champions.
Over the last 13 years, Lisa has been instrumental in building Champions Career Centre and helping to establish Champions as specialists creating a fundamental shift in perceptions of persons with disabilities in the workplace. She now proudly holds the Executive Director position.
As a life-long learner and inclusive leader, Lisa's work includes:• Presentations at various conferences focused on career planning, disability and accommodation requirements, and establishing a culture of diversity and inclusion.
• Working with employers on disability and diversity policies, working to increase the presence of persons with disabilities in the workplace.
• Coaching clients on career planning, job search, disclosure and employment retention
• Promoting the inclusion of persons with disabilities in the greater Calgary community through media interviews, social media and networking.
• Chair of the Calgary Chapter of the Career Development Association of Alberta.
• Co-Chair of the Private Career Development Contractors Association (PCDC).
• Board Member – Persons with Disabilities Chief Advisory Board, Calgary Police Service.
• Committee Member – Community Futures Treaty 7 Annual Disability Symposium.
• Member – Access Calgary Focus Group.
Under Lisa's leadership, Champions has reached number of impressive milestones – including
- Recipient of the 2011 Premier's Council on the Status of Persons with Disabilities – Award of Excellence in Employment.
- Helped over 40,000 individuals with disabilities with their employment goals
- Delivered over 15,000 workshops
- Since 2009, 85% of clients who secured employment were still working at 6 month.
Lisa's impact on the community knows no bounds. The legacy she continues to leave extends with every life she touches, every conversation she has, and every hour she spends promoting the vision of an inclusive community. The lives Lisa has impacted include, but are not limited to
• Clients who have accessed Champions Career Centre services
• Employers
• Community partners
• Champions Career Centre employees (past and present)
• Champions Career Centre Board Members (past and present)
• Fellow members of the various Boards and Committee's Lisa sits on
• Delegates at Conferences where Lisa presents
There is hardly an evening or weekend that goes by where Lisa isn't doing something to help support the vision of an inclusive world for Persons with Disabilities.
Help us recognize her tireless work and the impact she's had on our community.
Help honour Lisa through a Community Impact Award.

It's not new, but it's new in my building and in my room. We've been experimenting with how to connect three different groups of students...in this case, my class, another set of class from a nearby middle school and a third group in California.
Our first attempt was to read aloud a book that was relevant to our unit of study. We constructed a list of vocabulary words that would be important to know as we read the book, one of the teachers developed a graphic organizer that helped students actively listen for information and categorize that information, and then joined together to listen. Our reader had embellished the read aloud with famous posters and art prints and stories that expanded what listeners were hearing.
By the end, we had developed a common experience for all three groups which will be important as we all move into the independent tasks. Everyone will be trying to decide if John Brown is a martyr or a terrorist using evidence from a set of common sources of information; everyone will be developing Google Earth placemarks showing important dates/events in the abolishion movement; and having an online dialog between the classes about what role John Brown played in the country's history.
Students intently listened and were highly engaged with the task. More than being a flashy technology interchange, it really came down to trying to understand some big ideas. Was it OK for John Brown to use "any means necessary" to accomplish his goal? Exactly what does that phrase mean? Have we seen anyone in today's world that believes this is true? What implications does all that hold for the kids in the room?
So why do this with the other classes? Couldn't this be done alone. Absolutely. But I believe we'll gain something more from having been a part of the group. If I didn't believe this, it would be a huge waste of time and effort to link up with the other teachers and classrooms.
- First, I think my class studies ancient history so the contribution of the 7th graders, who study American history, will be invaluable as they serve as our experts in that field.
- Secondly, Mr. Miller's class has done far more with Google Earth than my class. So I'm hoping his students to be our "go-to" technical consultants when we run into problems.
- My students are learning a new technique. Realizing after this, the kids had little idea about how to behave or interact in this kind of learning exchange, I have the opportunity to expand the environments they know how to use. I can only imagine that this kind of online conferencing will be more important as time goes along
- Hopefully my students will use their moderating and commenting skills with another set of people....another way in which to practice and get better and better. These higher level thinking skills of evaluating, finding merit in other people ideas, being respectful and creatively finding mutual areas of agreement are increased with a larger community of learners.
If you have any classroom materials that would help me better lead my students in fine tuning their listening skills during a webinar, I'd be thrilled to hear about them. I wonder if I shouldn't tap into their sensibilities....maybe allowing for backchats or Twittering of some sort. Some way to keep them engaged and listening....digesting the information that flowing past them.
I've never done this before so I expect problems, setbacks and frustrations. Honestly just having that in the back of my mind helps me tremendously in not giving up and really keeping a sense of humor.
We had lots of glitches (video problems, audio problems, I couldn't find a webcam to work with my school computer, I didn't have the dongle I needed to connect my mac to the projector, the sound system kept turning off because I was using 2 video projectors which responded to the same remote control)....but I was just determined not to give up. I enlisted the help of my techiest kids....together we searched for ways around all the obstacles. This part was quite fun because they thought of as many solutions/work arounds as I did....so we really felt like joined-learners!!!
I'll keep updating folks on how this project goes. If you have ideas on how to make the video conferencing go better, please let me know. Or any ideas on what you've done to make this kind of learning work out better...I'd sure appreciate hearing your tips and tricks. Until later...Cheers.

We like ingenious apps around here and Metrowe fits the bill nicely. It's an app to keep track of how much money you owe or are owed. But it's not a bill manager for credit cards or businesses, but rather a tool for keeping track of personal expenses with friends and colleagues. For instance, say you lend someone $20 or pick up dinner one night, you can enter that info in Metrowe for easy record keeping. Vice versa, you can add in money you owe others, including noting what it was for.
The app has contact-integration, meaning you can really personalize entries with no effort. It also has a Live Tile that keeps track of your net value (owed vs owes) and flips over to show you your latest entries. On top of each entry, it records a history of transactions for individuals and allows you to 1-touch email them as a reminder--once again, very slick.
The app is very well designed (lots of Metro), slick and pretty darn useful. We love the Live Tile and contact-integration as it really makes it feel native. But if we're going this far, perhaps the dev can add camera integration too--so you can photograph that dinner or drinks that you bought everyone, why not? Shoot, even location info would be a good addition too. Regardless, as is the app is quite good and we highly recommend.
It fetches for $1.29 in the Marketplace and has a free trial.

Long time, no blog posts….first it was Stardew Valley's fault (highly recommend that little game) and then it was because I got a new job! Our weekend schedule has been very busy, and my new job means I have no time during the week. I've been hankering to play the Sims for awhile, so hopefully I get to do it today!
First, I wanted to get the site caught up!
- A new Gameplay expansion is coming! I was hoping for an actual expansion pack, preferably one with family stuff, but this will do for now. The game pack expands the Sims to include restaurants. Not only can our Sims eat, have parties, and go on dates in restaurants, but they can also run their own restaurants. It promises to have lots of new recipes too. I love food-themed things, so I'm not too disappointed:
- They are also promising a new kids-themed stuff pack. As I said, I want more family *game*play, but I don't mind getting some new clothes and toys for the kiddos since I love playing families.
- No more Blossom May! So my absence from the game made me once again miss the Spring challenge (:::insertagrumpyfacehere:::), so this makes Blossom May sort of useless. I'd rather spend my time finishing up the Bachelor challenge and working on Martin's Legacy. I also have my mind on a Castaway challenge, if I can manage to find more playtime.
- I'm going to be continuing to eliminate old content from this site in order to make space for the new content. I have too many followers (thank you!) to switch websites, but I don't have enough spare cash to increase my storage space on this site. If you have any other suggestions, let me know!

The UFC's newest division scored the first ever European champion before even Conor McGregor's dramatic victory at UFC 189. Joanna Jedrzejczyk has been on a tear, showing dominant aggression and lightning fast strikes that have overwhelmed her last two opponents while still standing. And in fact, when we look at the numbers for the Women's Strawweight division to date, we see that the champ has been backing up her performances with solid stats.
Fight Metric's Significant Strike is the basic unit measure of output in MMA, as it tends to correlate highly with fighter effectiveness and in success in a specific fight. For those who haven't read the chapter on this in the "Fightnomics" book, just know that Significant Strikes are all strikes while standing at a distance, plus power strikes only in the clinch or on the ground. It excludes light (jab) strikes in the clinch or on the ground. They're the strikes that do damage and help win a fight. Generally speaking, landing more often is good, and getting hit is bad. So that's why Fight Metric tracks these two basic stats of Significant Strikes Landed and Absorbed per Minute for each fighter.
Let's assess the young Strawweight division fighters on their performances to date. Some newer or unranked fighters with only one fight have been excluded. These fighters are ranked in the graphic below by the differential of Significant Strikes Landed per Minute minus Significant Strikes Absorbed per Minute. And right there at the top, outlanding opponents by 3.5 strikes per minute, every minute, is the current Champion, Joanna Jedrzejczyk. But how do the rest of these ladies stack up?
Click image to enlarge.
For more on these and other MMA performance metrics, get the book "Fightnomics."
Leading the Pack
Fighters who land at the top of the list are getting it done consistently. Hit, and don't be hit. Although we're just a few fights into the evolution of this division, undefeated champion Joanna Jedrzejczyk is already dominating the competition on the statline. She's among the more effective and highest paced strikers, but also tends to take minimal damage. Only Michelle Waterson took less damage, and that was just in one fight.
Jedrzejczyk has scored two of the three total TKO victories that have occurred in the division's 25 fights to date, and she's the only fighter with four UFC appearances. Her +3.5 differential score may not seem like a huge number, but it ranks among the highest of all UFC fighters. For perspective, Cain Velasquez is at 3.8, and Georges St-Pierre was a 2.4. The next closest among fighters with sufficient sample size is TJ Dillashaw at +3.1. Of course, we must point out that the nascence of the division, and therefore the still growing competitive forces, allows for a superlative fighter to better distance themselves from the rest of the pack. But right out of the gates, it's no surprise that Jedrzejczyk is already turning heads.
Trying to Catch the Leader
But who else might have a shot to steal the belt back from Poland? Some interesting contenders include Joanna Calderwood, an early TUF favorite who competes this weekend at Fight Night 72. Though she has lost twice by submission, should she eventually earn a title shot she would certainly make for a more competitive striking matchup with the champ than recent opponents thanks to her blistering pace of output.
Another potential contender who would surely have the UFC's support is Paige VanZant. She has more than doubled the Significant Strike damage compared to her opponents in her 2-0 UFC start.
Tecia Torres also makes a compelling striking matchup for the current champ, as Torres has performed similarly to VanZant, despite succumbing to superior submission artists in prior fights.
Still in the Race
The list of fighters who are still well above average includes No. 2 ranked Claudia Gadelha, who lost a spilt decision to the current champ, and is the only one of Jedrzejczyk's opponents to still have a positive effectiveness score. A rematch could definitely be in her future.
Other notables, like newcomer Michelle Waterson, probably need a few more fights at Strawweight to determine contendership, but she already has a fair bit of support behind her.
Randa Markos has lost twice in TUF/UFC action, but only to highly ranked title contenders. Anyone with a strong wrestling base that can actually use it against the champ is a threat to the belt.
And it's too bad the matchup this weekend between Bec Rawlings and Joanna Calderwood was scrapped due to injury, as it might have turned into a barnburner between two of the divisions highest paced strikers.
Falling Back
Several highly ranked fighters are low on the chart for different reasons. In the case of Jessica Penne and Carla Esparza, we have two grapplers who were severely outstruck on the feet by Jedrzejczyk in title fights, and have yet to rebound and build their fight history.
Another fan favorite, Rose Namajunas has only had one official UFC fight, and it was also a loss in a title fight – at that time to wrestler Carla Esparza. Rose Thug, along with Penne and Esparza should all creep back up the statline as they face less elite competition in their next outings.
Need to Get Back on the Track
Some fighters at the bottom of the list have taken a lot of damage in the UFC so far. That includes Alex Chambers, Seohee Ham, and Angela Magana, who are collectively 1-4 in the division inside the UFC. But it's hard to dismiss these fighters given the talent they've faced, as all four losses came against ranked opponents.
