Linear actuator controller

Using Arduino Motors, Mechanics, Power and CNC

Hi,

I'am looking for a cheaper alternative for the "Pololu Jrk 12v12 USB Motor Controller with Feedback"( http://www.pololu.com/catalog/product/1393). 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?
