Hi guys,
I've been hard at work making a small, single board hardware platform for stabilization/autopilot purposes.
The board is very small. Currently it measures 1.5"x1.1" (39mm x 28mm). It runs a 16Mhz Atmel Atmega328p.
Also, included on board are a 3-axis mems gyro, 3-axis mems accelerometer and a 3-axis magnetometer (no in the picture above).
Input voltages are 5v-16v.
The board can see use up to 16 I/O ports for PWM (in/out), external modules etc...
There's also a I2C header for external I2C units.
The alpha boards are already running a cut-down DCM code:
I'm planning to implement fist a version of the Ardupirates code.
If you're interested in one of these please drop me a line here or via email (erezraviv@gmail.com)

I like the compact version, very clever Nice!!
I fly in Shomrat (when I have an airplane :)
Porting all of Ardupirates is loking completely feasible. I have most of the "heavy stuff" in and the code is just 10K. Main loop is only 5msec and I think I got the HP and LP filter to an optimum point.
Here's a small demo of "gimbal stabilisation". Since I don't have a compass yet there is some yaw drift.
I'm working on a quad as we speak. I'll have a flight demo by the end of the week.
Almost all the parts are here. The toughest part were the Magnometers. Almost no-one has them and I don't want to buy cheap Chinese Knock-offs.
The HMC5883L does look nice but it won't be available until May. The HMC5843 do the job well enough. Now that I've secured enough units I can promise to start delivering within 3 weeks.
The waiting list is getting longer :)
Thanks, I just downloaded it.
Still, they say it won't be available until May. I got a local source.
They won't be available until late April. There's no datasheet either.
The 5843 OTOH are still available and well documented.
Looks great. However the HMC5843 is EOL'd. HMC5883 is its replacement. Slightly smaller with better specs. But unfortunately, I haven't found a source for that yet, either. It's really been a tough couple months for mag sensors.
