Just over a year ago, I was wandering around the Maker Faire with a pocket full of prototypes to show off. That was shortly before life got even more hectic than usual and I ran out of time for working on Fun Stuff.
One of the things in my pocket was a Sho'-Fly Pi Crust: an inertial + magnetic sensor platform to plug onto a Raspberry Pi.
Looked kinda like this, which someone else has done in the meantime.
Dunno how they're doing the servo connections; mine has an ATmega328 running an Arduno sketch that listens on I2C and generates servo pulses on 8 outputs.
And mine intentionally omits the onboard GPS, owing to concerns about the arcane U.S. drone laws. There's a connector for connecting a GP-635T, should the user be so inclined.
Main reason mine didn't go beyond sample hardware was that, in the limited time I had to work on it, I couldn't make sense of the rate-gyro outputs, the gyro and the algorithms for dealing with such both being poorly documented.
In other news, it seems my vacation/walkabout plans get postponed again, owing to the pile of "must do first" tasks getting more taller than shorter. But at least some of them pay by the hour.
