Brad is building this pretty rad GPS/accelerometer tracking device to measure the performance of his model rockets. The telemetry data will also be used to help recover the rocket. His current version uses an ADXL330 accelerometer (also found in the Wii nunchuck), a long-range xBee transmitter, and a PIC 18F microcontroller.


I particularly like the way the surface-mount-only accelerometer chip is mounted.
Update: The chip is mounted in a slotted header, or alternately a DIP component carrier. Thanks!
