Since I have yet to receive a power meter, I'd like to bounce this off of everyone that had a chance to try it. I've purchased a bunch of the GB diodes, and so far, each one has performed far better for me after removing the can and the built-in window. I'm wondering if it's more than just...

Okay, here's one for the laser chemistry pros. I just completed the build of one of the GB blu-ray diodes, and I noticed that when powering the diode at the very low end (below the commonly reported threshold), this diode was indeed lasing and also putting out non-coherent white light! At first...

While shopping at Lowe's Hardware for potential parts and tools for my projects, I came across this flashlight for only $18US. It's a single cell AA flashlight based around a boost converter to drive a 1W LED. The boost converter itself is self-contained, and on a separate and enclosed board...

Aixiz is currently advertising a 200mw red diode for $40US on their main page. Anyone tested this one yet, or have any feedback on it? From the main page for Aixiz, scroll down to the diode listed for the Kip Kay project (second one listed)

After a night of no sleep, I decided to post the resulting schematic from an attempt to trace out the Aixiz driver. This probably will not work for most other lasers without modification, so I'm posting it only for information and discussion ...
