[ExI] self-riding bicycle test board

All is not lost.  These little Seeeduinos have mass of only 3.047 grams with header pins, less than copper pennies minted before 1982.  We hard-wire the gyro package and stack a coupla watch batteries, we will still come in at less than 10 grams.  The micro SD interface might be a bit more tricky, but we are still not busted: the Seeeduino has 256k onboard memory which might be enough for a short flight.  

 

If this approach works, then we hardwire the SD card without the interface structure.  That might work.  Wouldn’t bet on it, but maybe.
