Sounds great. I look forward to participating.
BTW, I started an opensource/openhardware project called the OpenServo (
http://www.openservo.com) a few years ago. The purpose was to convert cheap servos into digital servos with features tailored for hobbyist level robotics. Digital servos geared towards robotics typically cost $100 and up. The prospect of converting a $10 servo into something that in some ways was better than the very expensive models was pretty appealing -- being completely open to hack the firmware being the best feature. I got involved with a robotics start-up that consumed all my time so another fellow picked up to continue with the OpenServo, but I learned a lot about AVR MCUs such as the ATmega168 creating the first few versions.
Much of the work I did with robotics servos could be applied to RC servos, but the 5g to 9g servos I use in my foamies are so small that things get very hard to work with at a hobbyist level at that scale. Besides, other than failsafe, I'm not certain what features might be added.
Now that I'm into RC flying I would love to put some of that experience into new projects geared towards RC flight. The Turnigy 9X looks to be an excellent platform to base some projects on. I'll keep my eyes open for ideas to pursue.
