Laser tripwires for Machine Project art heist

Why are we building laser tripwires? My friend, we’ll call him Agent Todbot, and I are creating a competitive art heist event for the upcoming Machine Project benefit. This means lots of fog, laser tripwires, and flashing lights. Competitors will try to get through, steal a piece of art, and return without crossing any beams.





To build this, we’re pulling apart a bunch of laser pointers, mounting them at carefully measured intervals (in Mister Jalopy’s museum behind Coco’s Variety), and pointing them at photosensors. Tod attached these to small acrylic discs to allow some slack in the system. We’ll provide more build details as we go.

    Do the black bars protect his eyes from the laser?

      with the odd juxtaposition of the old basement, vintage stereo and cabinet, and bottle of soda with the laser pointer and cell phone…

      Actually, the black bars protect the lasers from Tod’s robotic glare!
