yeah the one i got isnt a flash light ,per se..zachtheterrible said:Hey willi, the LED project is going terribly! Q1 keeps on shorting out the positive and negative rails for some reason. Its on all the time, instead of only being on in pulses. I have NO idea whats going on with the bloody thing! Its also oscillating @ 370khz! Its only supposed to work @ around 200khz.
since its already on a PCB, its very hard to experiment with it and change out components. I just ordered the same parts again from mouser. Im going to put each one on a PCB, then run wires off the PCB so that I can put it in a breadboard and experiment.
I am not giving up on this project! It will be such a great thing when it works. Just imagine a flashlight that runs for several days at the same brightness, even when the voltage drops to 1v!
Ill have to drop by lowes and check that thing out.
