    Default Mechanical Laser Show: OK, which one of you guys did this? :)

    Just saw this on the front page of Reddit:



    Link: https://www.youtube.com/watch?v=_dtBUiaAqRE

    3D-printed cams driven by a crank provide X and Y motion to a green laser pointer who's front end rides on the cams and pivots around the back end of the pointer which is held loosely in place with a rubber band...

    Result? Instant laser graphics!

    OK, primitive graphics, but even so this is a very cool idea. The video explains how he calculated the varying radius of the two cams for each pattern. It's really quite clever...

    So out with it: Which one of you guys did this?

    Cool! He uses a Go program to generate the shapes for the cams:

    Brilliant lil' project-or.. Though I imagine, invariably we will see turn up on U2B the 'DIY CAM-DRIVEN 40 WATT BLUE LAZOR SHOTGUN!!'

    Now that is inspired!

    For what it's worth, I sent the guy a PM on Reddit and he replied that he is in Los Angeles. He was not aware of our community here, so I extended an invite. I also mentioned SELEM, but he indicated that cross-country travel wasn't an option at the moment. (Damned shame too, because this would have made for a cool presentation at SELEM...)

    Still, if he does stop in to check out our forums, maybe he could link up with some SoCal-LEM veterans!

    Brilliant - maybe even enough to convince me to fire up the 3D printer and build one.
