Take one battery and connect a LED directly to it, add one magnet and wrap it together with some tape and you have a LED Throwie. Accoding to Graffiti Research Lab, that developed this, one of these units will keep on glowing for about a week and with a hole bunch of them you can run downtown and do some electronic graffiti. And yes – they did it and here is a video of it. What you see on the picture is a whole bunch of these throwies stuck together. After all – they’re magnetic. Read about them over at Instructables |
