Just an update, it lives! The LOC was replaced with a SOC from a DVD drive (Sony/NEC AD-5170S) which runs well at ~320ma peak and settling down at 300ma.

The model is a TANK007 available at DX, the smallest AAA host with a clickie I could find. It did not come with an amc7135, it came with its own boost driver, but I didn't trust it with the diode, hence I made my own board. I used a cut down AixiZ module, but the fit was loose enough to warrant...

I assume this would be easier with higher powered diodes since there's more energy to contend with. As to the mechanism, thanks to Wikipedia, I guess that it's caused by the facet being overloaded by having not only the light exiting, but the light reentering, being focused down by the lens and...

I built this little 10440 powered LOC 660nm laser with an AixiZ module being fed 350ma from an AMC7135 driver board. It worked quite well for a few years, had decent cycle times (2 min on would make it warm), would cut through plastic, ignite matches... until I pointed it in the mirror back at...

One 445nm diode with a glass lens please! EDIT: wow, been lurking here for a year with only 2 posts...

I've been doing a lot of anomynous lurking around these forums but now I want to share something with the community. On with the show... For less than $30, it is possible to build a single AAA battery powered laser running at about 70 mw which includes the price of the battery, host, diode and...
