LED “Throwies”


Okay, this may be the coolest little hack I’ve ever seen, and simple enough that even a non-engineer like me could do it: LED “Throwies”, brought to us by Make Magazine. They’re basically little LED lights connected to a battery and a magnet, which you can attach to any ferromagnetic surface simply by tossing it at it. Ever wanted to see your name in lights? Now’s your chance! Be sure to check out the excellent video by Resistor and Fi5e.
