I have too much money and time in this to either give it away or let it sit on my shelf any longer, I just don't have time for robots now. It is on Ebay:

I have been fascinated with the idea of building my own, two wheeled, balancing robot unfortunately I do not have time to continue work on it and want to pass the project on to another enthusiast. I designed my own PCB, which attaches to a Keil MCB2100 evaluation board. This board features the Philips LPC2124 ARM controller. The board has a JTAG interface as well as serial interface which supports serial code downloads using the free Philips ISP tool, available on their website. The PCB "daughter board" has on it:
a.. Switching regulator b.. ADXL202 Accelerometer c.. Two LMD18200 Motor Driver ICs d.. CG-L43 Solid State Gyroscope and associated signal conditioning e.. AD12038 12-bit 8-channel ADC. This reads the gyros output voltage and also has extra channels for additional sensors. f.. Prototype Area
The board plugs into the MCB2100 evaluation board with a .1" header and is mounted via stand-offs.
I have verified the electrical connections and have adjusted the gyro signal conditioning so that I see a nice output to the ADC.I have quit a bbit of code for these ARM micros and also the ADC, available upon request.
Schematics and board can be seen here:
