After deciding to update my focuser control to use a stepper motor, i also decided to do something about my messy wiring and connections, a trip to jaycar and started working on this box...
It does:
Focuser control with arduino
Temperature sensing
Power for the mount
Power for the Telescope Fan
Usb hub for CCD camera, Guide cam, Filter wheel and Telescope control
Fused 12v input
Spare 12v port
I am happy that my wiring is way better now
