Lego Laser Plotter

Step 3 The laser mount

This was the hardest to design but it works very well. There is one arm on each side that move up and down to activate the laser. A small piece is slid over the button holding it down without constant motor activity. The laser I used is the Executive Classic that can be found here. The model that I received is a bit over powered so I recommend using the 35 mw. The lens I used to focus the laser was from an old gun sight that is attached to the laser with some electrical tape.
