Nice workmanship Roger.
I built a double arm drive and used an Arduino board. I think you can get them from HK for about 10-15 AUD.
I wrote the code and made the shield for the electronics. It started out ticking the motor away at 1 rpm. Later I added a 5:1 gearbox and increased the rpm, which was much smoother and provided a big increase in torque - Tamiya hobby planetary gearbox sitting around and pressed that into service.
