After whetting my appetite with a repurposed Darcy Metal Gear build (that pulls so much from 3 AAA's that I had to track down some NiCD's to bear the brunt of it), I started looking at options for a 445 build. While Jayrob, Flaminpyro and others showed us plenty of host options, I decided that...

"Fade Out, an eye-catching visual display system developed by media artists Daito Manabe and Motoi Ishibashi, uses laser beams to "print" ephemeral glow-in-the-dark images on a wall-mounted screen coated with photoluminescent paint. After the computer receives and processes a digital image (in...

AW 2900 mAh 18650? - CandlePowerForums Same discharge specs as the 2600mAh cells. Looks good for 445nm 1W builds.... thoughts? Anyone tried these yet?

The discussion in this thread on low power usage for 445nm diodes, which lase at a minimum 200mA or so, leads me to this question for our driver experts. To me, the best option for operating this diode at low powers, given the minimum lasing current and very low efficiency at those currents...

I've got one of the red lasers that runs on 2xCR123, has a brass ring in the midsection, and is focusable, that I *think* is known as the Sentorch, because it came in a group buy run by Senkat a year or more ago. The diode and driver run fine, but the switch is utter crap -- a solder blob is...

I just received an upgraded Galileo from daguin, which has been upgraded to a 200mW module (I assume from O-like, or DX). It looks just fine, but there's no indication of polarity. The module is the sort that has a coiled contact sticking out of it. This is a RCR123A setup (3.6V). I don't...

Unfortunately, it was me :P Got the magic smoke and all... I know that smell anywhere. So: is this fixable by a hobbyist, or are DPSS units too precise? Can parts be had? Spec info: this is a 3.7V single cell lithium unit, green DPSS =~ 250mW or so.

How sensitive to temperature variations should a 660nm red diode be? Does this vary wildly from diode to diode? My Sentorch seems to have a pretty wide swing depending on temperature. I was noticing that it seems to lose some intensity after I've been using it a bit. So, I sat it in the freezer...
