I have a 12 v servo that I would like drive with a phidgets 1 servo controller. Is it possible to do so by hacking a usb cable's power wires and routing 12v through the board? It's looks as though the power goes through the chip.

Thanks!

You don't want to get into hacking the USB cable. Besides, you'll fry the Phidget servo controller.

All you need is a Y splitter:

One end gets connected to a battery, one to the controller, and one to your servo. Just be sure to clip the power wire going to the controller itself.

Ah, I see now it needs a common ground. I was bypassing the controller all together with power and ground. It works now. Thank you.
