Segway And Input Filtering


[Kerry] is building a segway type vehicle for a senior project. Though it doesn’t appear to be done yet, there is some good work finished. As with any balancing bot, it relies heavily on input from a gyroscope, and at least in this case, an accelerometer. That data can be very messy. The sensitivity of the sensor means that people often end up with vibrating or drifting in their projects. [Kerry] has put some work into finding a method of smoothing that results in fast, accurate, but smooth reaction. You can see a video of some comparisons between methods after the break.

Accelerometer Controlled Pong


[Adam] sent us this cool game he made. It is accelerometer controlled pong (translated). The screen is a Nokia 3310 LCD, tied to an ATmega8 for the brains.

The whole thing is encased in an iPod nano box. this looks like a pretty fun little game, though we’d like to see someone attempt a two player match with it.
