All,

Thanks to everyone that has responded both on and off list. For my first attempt at finding a non-mechanical solution I plan to use the MEMS accelerometer (for El) and magnetometer (for Az) solution. When still exploring the Potentiometer solution, because of space requirements and other factors I was pricing out multi turn potentiometers. For the gearing ratios I needed, I required about a 5 turn potentiometer, which at least according to digikey and the quick search I did, priced to about $20.00 apiece. The MEMS Magnetometer (HMC5883L) and Accelerometer (MMA8452Q) each price out to less than $20.00 each on sparkfun, so I'll actually be saving a few bucks.

That's the plan, at least for the first iteration. We'll see how it goes!

Thanks again to everyone!

Go Team AMSAT!
