So, im having absolutely NO luck with the PCB. It only seems to work on the breadboard. The two PCBs that I have created for this project have not worked at all. I want to use the one from the chip-torch article, but i cannot figure out how to size it down to the right size. Whenever I try, the quality becomes terrible. Can anyone get it to the right size? I have tried changing the file formats to .gif and .bmp, but the same thing happens.

Is that any good? You'd have to tell me the exact size you wanted i though. Alternatively, download "irfan view", it's well worth having anyway.

What is irfan view? Is that what you used to do it? Oh yeah, i just realized it would be impossible for you to give me the right size without actually printing it out and stuff. ill have to do it on my computer.

Irfan view is a free program that nobody should be without in my opinion, it solves most image problems there are. Yep, its what I used. http://www.irfanview.com/

I ALMOST had this thing finally mounted and working in a flashlight (i got the PCB to work), when i blew out another $11 LED!! :evil: :evil: :evil: I cant believe it! I think what may have happened is that a decoupling capacitor accidentally got disconnected while I was working on the cirucit and it let large voltage spikes through the LED. Do you think that's the problem? EDIT: I figured out why it burnt out. It was not the decoupling capacitor. When there is no load on the circuit, the circuit produces around 30v. When I connected the LED I saw a small spark. It was obviously enough to zap the LED. The project is almost done though. When I get my next LED, it will finally be complete and ill post pics :lol:

I SUSPECT THE INDUCTOR MAY BE PARTIALLT SHORT. PLEASE CHECK. 2. ple check the electrolytic 220uF for leakage.
