Tracker board

Gather the parts required for the tracker, and build the board. I used perf board with .1" on center hole grid.
The power transistors need to be mounted with insulating washers for the screws, and insulating pads between the heat sink and the transistor collectors.
The layout shown in the photo with roomy construction makes it easier to build. Once the board is built and tested, I glued it directly on the plywood support for the large dual satellite dishes. The opto sensors were soldered to the shielded cable at right angles, and then covered with epoxy putty, with an embedded ring terminal to act as a mounting system.
