An intermediate-level physics laboratory: A system of two coupled   oscillators with low-cost accelerometers
  We describe an intermediate-level physics experiment beyond the first-year, which uses versatile, low-cost accelerometers (Wiimotes for the Nintendo Wii gaming system) and scientific-computing software for numerical data analysis. It is designed to help students to develop better understanding of a system of coupled oscillators and Fourier transform.
