All.

I am looking into controlling my EXOS-2 (EQ-5) mount via a lap top linked to a Arduino or Raspberry PI using the ST-4 port.

Does any one have any experience of doing this? Or have any advice.

I have found the plans and instructions on using an Arduino to do on Hackaday link below.

Any comments/help most welcome.
