Chris J. over at GRYNX was so chuffed by all of the attention he got from his Tic-Tac flashlight, that he’s posted a new project, a 3-bulb LED light made from a 9v batt, three bright white LEDs, and a battery snap made from a dead 9v. One cool thing about this project is that, by using three LEDs on 9volts, you don’t have to use a resistor in the circuit, so the parts count is only five. You can also add a magnet to it to create an attachable light, or maybe to use in some electronic graffiti.
