Linear actuator controller


I'am looking for a cheaper alternative for the "Pololu Jrk 12v12 USB Motor Controller with Feedback"( I want to control a linear actuator with feedback, like this one:

Does anyone have a good suggestion?

Thanks in advance!

You might use one of the below linear actuators with feedback, an h-bridge from ebay, and the arduino to do what you want.

Check out satellite dish positioners. For feedback, they use a microswitch attached to the drive motor giving a pulse each rotation... This translates to one pulse per mm or so (varies) of the actuator.

Thanks for the advice. Zoomkat I have one question, how do I connect the feedback with the ardruino?
