Project of miniquadcopter
An original idea belongs to @tobbeanton from Bitcraze AB.
An idea was to make my own controller for quadcopter. You can find here schematics (original files for P-CAD with library are included). Also there are firmware and source code in repo.
The device based on Atmel microcontroller MEGA328, have two sensors: digital accelerometer LIS331DL and digital gyroscope L3G4200D. The flying now is unstable and I'm working on it.
