So I accidentally ordered a 405nm diode instead of the 450nm I was looking for. I'm not the biggest fan of this wavelength just by personal preference, and would like to recover some of the money. The diode is a Sharp GH04W10A2GC diode with an ACS1500SE driver set to draw 700mA. I don't have a...

Thought someone might get a kick out of the fact that I found all of these brand new online recently (except the bottom. Bought it used and broken). But I couldn't resist as a fan of laser pointers. I would love to take them apart and upgrade the diode but they seem tough to take apart without...

Just finished my first 2 laser builds. I used a 488nm (55mW) and a 520nm (80mW) and both are powered with AAA batteries. They are perfect for general pointing and relatively eye safe (assuming you don't catch a direct reflection) and I think these pens are hands-down the coolest host for a laser...

Hello, I was just wondering if anyone knows where you can buy the silver "Danger" Stickers that you see on laser pointers. I have many with no labels and many with incorrect labels. Honestly I like the look of them, especially on smaller pens. If anyone has a source, please let me know! Thanks...

Hello, First of all, I know you guys aren't medical professionals, but I'm looking for some insight until Monday when eye doctors are open. I recently purchased a 1.5W laser using the NDB7875 module. I ordered glasses at the same time, but they did not show up before the laser did. I didn't...
