3 Watt 1AA torch Super Bright LED Flashlight Lamp light - eBay (item 280442891750 end time Sep-21-10 02:40:43 PDT) Not sure if anyone would want to give it a shot...? Looks like a luxeon?

So I just started thinking about lead and how much of it is in our lasers. My main concern would be from Chinese hosts, the cheap-o pen lasers from ebay or any of the components that come from china. I was wondering has anyone ever tested this out? If so what method (XRF System, chemical or...

Ok, so I know this was mentioned in a couple of other posts some where and it turned out to be the battery. I have checked the battery (aw 18650) and a few others and they all do the same thing (all have a full charge). I have the boost driver set to 532ma. So what happens is it turns on for a...

I am wanting to try out a few new lightboxes and I like the one used here. The next and previous buttons are nice and the chance to have it resize (upon clicking) to a large version is nice. Right now I'm using mediaboxadvanced, but I'm not using many videos so I'm sucking up more bandwidth than...

Hey guys, I'm looking to buy a few 10440 batteries and a glass line generator. Let me know if you have any! Thanks. EDIT: Quisp - Hooking me up with the 10440s.

Hey everyone, I'm curious to whether anyone would want to do a GB for AW batteries. I should be able to get all of their batteries unprotected and protected. A AW Protected 18650 would be around $15 shipped in the US and about $18 shipped international. Of coarse these prices could come down or...

I can tell you that my video isn't the greatest quality, but it's something very neat. Video #1 - Lights On Video #2 - Lights Off I will try to get some better video and maybe a few HD pictures! :beer:

So today I got my the two lasers I ordered. The green 100mw I received is fantastic very little to no divergence. Before I go on to the rest of my post I want to make sure I understand divergence correctly. Divergence is how much the diameter of the dot grows or expands over a certain distance...

I'm in need of some safety goggles (660nm and 532nm), I wondering if anyone had any they didn't need any more. I have been looking oem laser systems and CNI. I would like a decent pair so price isn't really an issue, but I would like to stay cheap as possible. Also IR blocking would be really...

So everyone knows about the endcaps you can put on the small cheap lasers most of us have or had at some point. What I'm wondering is it possible to make or buy a custom endcap that says something or displays a custom image? OR Even using a higher powered led with some type of lens.

Ok, so I'm new as is finally getting around to registering, but I have lurked around off and on for a couple years. I had a 150mw red I built awhile back, but either it was stolen or lost. I'm now looking for either a quick easy diy or a complete build. I really like jayrob's builds as well as...
