DIY Motor Controller for Meade 1209 ZSMF #5692833 - 02/21/13 02:05 PM
I'm sure someone else is still having a problem like this, you found a 1209 unit but no handbox, or, handbox is too costly. I have details of what I build including schematic as well as the links that I used to get the idea together. This is the plan for a forward / reverse single speed motor controller that you can use on the 1209 unit, and perhaps other units if they take a stereo input jack. this is just a normal H-bridge circuit.
