This looks like it might make a good basis for a pretty decent DIY 
vario/flight instrumentation system. Only $25.


"The SensorTag works with TI’s TPS62730 (step down converter), and 
includes TI’s TMP006 IR MEMS temperature sensor, humidity sensor, 
pressure sensor, accelerometer, gyroscope and magnetometer."

Use the pressure sensor for altitude, the gyro/accel/mag for vario (and 
possibly, if resolution is good enough and drift is low enough, inertial 
navigation and groundspeed), and temp/humidity for curiosity. Use your 
smartphone for info display, and possibly GPS (to counter drift on the 

I'll be in California from 9/23 to 11/4, roughly. Anyone want to work on 
this with me?
