Wiimote Fun - Wiimote as a car accelerometer

Make: - Wiimote as car accelerometer

"This fairly simple hack uses a Nintendo Wii remote to capture G-force readings in a car, dump it to a CSV (Comma-Separated Values) text file, and then graph it via Excel. The results aren't the most precise, but apparently good enough to give you some useful feedback on car mods." [Description leached in full]

Just the other day I was looking for more reasons to get a Wii... lol  ;)
