So for the past two months I've been working on a quadrotor project, and I've designed an ARM based board just for it. Contains a TI LM3S9B96 ARM Cortex-M3 (not out yet, some how convinced TI to send me a few), 3-axis gyro, 3-axis accel, compass, zigbee, 4 motor pwm outputs and temperature sensors (also tons of breakout pins). I plan to make a shield with gps, barometer and a couple of other things.. Just now I have confirmed the board completely works, and I'm beginning to get into the kalman filter and pid control loop.
I'm just wondering how many people would be interested in the board. I'm likely to make it open source hardware/software.
