- Many options, since we can build ourselves
- If it fails, we only have ourselves to blame.
AED Electronics R-DAS:
http://home.iae.nl/users/aed/rdas/rdas.htm

- Measures acceleration and barometric pressure.
- Easy to configure from a PC (software included).
- Large memory for storing 8 minutes of data (including 2 seconds of pre-launch data).
- 6 analog and 4 digital inputs in addition to built in sensors.
- 2 igniter outputs driven by 9 volt battery or capacitor. More available on expansion boards.
- Integrates with available GPS board, air-to-ground telemetry transmitter, etc.
- Costs around $250
ATHA Aerospace AFC-877 Flight Computer:
