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!
