This project was conceived during a chat with Alex where we wished we had a laser cutter and thought we could make one out of an etchasketch. Alex, this instructable is for you. Keep on inspiring me.
--Update: Samuel just built one of these things! He did a much better job t han I did ; P I can't wait for video!--
Here's a video showing the basic setup:
This project demonstrates a simple hack to create a large format laser cutter utilizing all the scrap electronics you may have lying around. If you have a broken scanner or two, the cost can be just about 30 dollars for the entire project.
