Back when I had an easier job I decided that I’d attempt to make a really simple, lightweight rotator that used off the shelf servos or stepper motor’s driven by an Arduino. Either interfaced with a PC or as a stand alone device.

Well, things move when you’re not looking and it seems like my bright idea was also several others, and whilst I’ve been busy not doing anything radio, others have.

I’d managed to buy a couple of servos off eBay and managed to drive them with the standard examples. Although the movement wasn’t as smooth as I’d have liked. Perhaps a couple of large capacitors would have helped but as I didn’t have anything suitable to hand I thought I would have a go anyway.

Well it didn’t work out like that. After spending over an hour installing the Windows 8 drivers (how to turn you off an operating system!) I hooked up the Arduino and wrestled with the servos. Either they are knackered or there’s something missing…..

Time to take a step back and reflect, or buy a few caps
