Auto On/Off LED Throwie This is my version of the LED Throwie. The design isn't mine, this is just my mod of it. In the original design, the LED Throwie is on from the moment you put it together. This can be annoying if you're planning to make tons of these, or if you want to make them ahead of time but not have the battery run out. Someone has already posted a mod that adds an on/off tab to the throwie, however I've taken it one step further: in this design the throwie automatically turns on when it sticks to something, and turns off as soon as you remove it! It's just as simple to make as normal throwies, and doesn't require any extra materials either! I'll point out that though this instructable may seem long or complicated at first, it's only because I wanted to make sure it was well documented. From the original throwie: Developed by the Graffiti Research Lab a division of the Eyebeam R&D OpenLab, LED Throwies are an inexpensive way to add color to any ferromagnetic surface in your neighborhood.

However, they did give me a great idea on this one. My friend Alison was making a joke while i was knitting one day that i should make a utility belt to hold all of my knitting/sewing needs. I just laughed, but when i had no homework the other day, i thought to my self "hey, i have this role of duct tape, and an old belt, maybe i should give it a try!" Questions? oh, and i wore it to school to, and oh boy the looks i got.
