I too need some help figuring out this barn door tracker thing! I have built mine according to Gary's page- here.. http://www.garyseronik.com/?q=node/52
I am stuck with the motor control circuitry! I 'attempted" to build one myself but my electronics soldering skills are lacking! Is there a controller or circuit board on eBay that I can just buy and plug in to this exact motor or do I need to find someone who knows how to build this?
Any help or advise would be greatly appreciated!
