[TriLUG] OT: remote controlled antenna rotator

[Ron Kelley via TriLUG]

Slightly OT, but I know we have a bunch of smart people on the mailer…

Looking to attach sort of antenna rotator to our HD antenna in the attic.  It is a smallish unit (maybe 10lbs) that needs to adjusted every so often, and I would like to use some sort of remote control device (electric lazy susan?) to avoid a trip to the attic.  Amazon has a number of pricey units, but I was hoping I could do some sort of low-cost DIY project with Arduino or Raspberry Pi. 

Any pointers?
