parts needed, generic heat bed close to size of the one on the printer already,
12/24v power supply
5 pin automotive 30a or higer relay
small thermostat control chip from ebay.
wire, buttsplices, and a mild bit of smarts

oh and i didnt cover this in the video, but the heat bed it turned on and off by unplugging power supply, i wasted no time on a switch. but you certainly can!!
