LED Throwie casing with auto-on
thingiverse
Electronic graffiti is made up of a magnet, LED, and small button battery. These simple components create an impressive display when attached to a metal surface. The project is popular for events like Burning Man, with PLA being the recommended material. To make one, you'll need a red LED (for longevity), a CR2032 button cell battery, and an 8mmx1mm rare earth magnet. Thread the LED leads through the holes, ensuring that the lead makes contact with the magnet when it sticks to a surface, activating the light. Bulk purchasing can bring the unit price down to about 50 cents per piece. Watch this video for more details: https://www.youtube.com/watch?v=AX7jA4NJV8s&feature=youtu.be
