So I've spent the better part of two weeks reading up on digital electronics to help me understand how this circuit works. https://ift.tt/2pMm1Jo learned a lot. It's a joule thief circuit that uses solar cells to charge a battery that will use a transistor to sense when it is night time and turn on an LED.I really want to make this into a lantern for camping but I'm having problems getting it on the breadboard.I lay down and solder everything up to the battery, but when I go to hook up the battery stuff starts to smoke. I'm using 3 AA NiMH batteries wired in series and putting the positive wire just after the diode and the ground wire just before the inductor on the positive rail.When I flip the two wires around I dont get any smoke but the Q2 and L1 get really hot.I think theres gotta be something up with the schematic as it has me connecting the ground of the battery and everything past it onto the positive rail. I'm 99.9% sure I'm wiring my breadboard according to the schematic. via /r/DIY https://ift.tt/2Waz43r
