=== 1W 445nm Lm317 Project with Photos! ===

Hi everyone,

I just completed my LM317-driven 1W 445nm project. I would like to thank DTR for the good diodes, and all the help and information in this forum. I've based my driver circuit off a standard Lm317 driver. This project was made to run off 3x CR123A batteries, which can be both Li or Li-ion.

That's a beauty:gj:

Oh lawd, she's purdy.

How much current are you giving it? Is it adjustable?

Thanks for the comments!

This one is running just about 1040mA. I decided not to make it adjustable since I didn't have suitable variable resistors lying around but it seems to be running just fine. The heatsink for the LM317 and diode seem to be working well.
