[Romado12187] just posted a walkthrough of his mechanical dry erase board project on Instructables. It was on display in the Microsoft booth last weekend at Maker Faire. Unlike [sprite_tm]‘s version we covered earlier, this one is built more like a traditional pin plotter. The construction was done entirely in [Romado12187]‘s dorm room and uses plywood and PVC pipes for the majority of the frame. The mechanical components were purchased from SDP/SI and the controller hardware are Phidgets. He included a joystick, but it also has a C# command line program for control. [Romado12187]‘s write up also has a lot of improvements to help make your first attempt better than his; buying a premounted board and being very exact in calculating motor power are recommended. Catch a video of the plotter in action after the jump.
