LED Throwies, pioneered in 2005 by Graffiti Research Lab as a kind of electronic graffiti, instantly became a classic maker project. Consisting of nothing more than an LED, battery, magnet, and ahesive or tape, these simple circuits can be assembled in mere seconds. They stick to any ferro-magnetic surface, making buildings, bridges, and other public structures glow!

Since then artists and makers have taken the concept and ran with it, creating indestructible waterproof lanterns, filled a hundred helium balloons and tethered them all together to create an etheral, floating sculpture, and connected them with Integrated Circuits that blink Morse code. We’re revisiting and updating this project with Extreme LED Throwies, the latest in our series of fun and simple Weekend Projects. Watch the project video below for the basics of building Throwies, followed by examples of Lanterns, Swimmies, and Floaties – with more examples and ideas on the project page.

And should you create your own extreme throwie build, be sure to let us know – we might feature your project here on the MAKE blog!
