Already evaluated the ADXL202. Works great, but too expensive for the application. It still needed a micro on it to provide zero offset, gain, and remote control, so for double the price we would have gained nothing. The capacitive sensor also had more data precision in less time. I'm using an ADXL105 to provide a pitch stabilizer (rate gyro setup) for one of my model boats. SHould be an interesting thing. The ADXL202 is going to drive the prototype directly until I get the 105 board done.

You guys should check out the Analog ADXL202 - its a two-axis 2g accelerometer. One chip, 1/4" square and about 1/8" thick, $20 in single quantities, and is trivially easy to interface to a PIC (I've got one interfaced to a F84). You can also get an eval board for $30 that has the chip mounted, you need to add two caps and a resistor, and you get a standard 5-pin 0.1" header. It gives you basically 0-90 degree tilt accuracy in both the X and Y axis. With two of them, you can get full 360 degree tilt accuracy. Its very cool tilting this board in your hand, and watching a servo move to a position that correspends with the tilt... Later, Jon
