I need an step/dir to +/-10v servo controller. I came across this http://www.uhu-servo.de/servo_en/index.htm which looks like an economical solution to the problem. However, while I have a basic grasp of electronics and can knock-up a power supply, I'm not capable of tackling a project like this without assistance.

I wasn't able to find a a simple circuit diagram and a component list on the site - basically I need idiot-kit instructions. Has anyone on here built one? Any help very much appreciated.
