Many years ago I acquired a rather shabby Apollo III projector. No control systems, wiring mangled but most of the important bits still there. As discussed on the old Observatory Central forum, I have been refurbishing all the mechanical parts as my Life and rotating hobby interests (Attention Deficit Hobby Disorder) allowed.
Today I reached a milestone with the first onboard testing of the new controller. The new control system is comprised of a Raspberry Pi 3B+ running a python program I wrote, DC gear motors in place of the old AC motors and assorted MOSFET modules and voltage regulators.
The Raspberry Pi can be controlled remotely using just about anything that can run the commercial (free) VNC Viewer program (phone, tablet, laptop).
Definitely still at the lash up stage, but real progress has been made.
pictures to follow.
