Multi-touch tables YouTube - Multi touch DJing Mixing Desk - HoloDesk this is a demo of LLP (Laser Light Plane) system there are a few more, all of witch are based on IR light. I think it's a great DIY idea and it involves lazors :wave: I am currently absorbing as much info as I can. would love...

Seems pretty cool. YouTube - iLaserPointer.MP4! It looks plugged into the headphones output of the iPhone. Does anyone know how much current does that provide? And voltage? Seems a weak 1-2 mW red.

I was looking at my beam today and was thinking "wow, wouldn't it be great to be a whole lot thinner?" And dpss green came into my mind. Now, I understand the basic functionality of a dpss greenie, but could the same thing be applied for a 405nm output? I mean you would need different crystals...

Do you have any idea if those circles in the light-spot are normal? What are they? It's a GGW higher wavelength diode set at 155mA on flexdrive in a Pocket Mini host with copper heatsink :D

Would a 415 nm diode produce a noticeable weaker fluorescence then a 400-405 nm one? I just bought a higher wavelength GGW and I am curious about this effect.

YouTube - Laser Pointers Take Down Helicopter The stupid thing thou is that no one seems to be wearing any protection glasses :thinking:

Hello people. I just put my hands on some broken dvd players and writers. In the first dvd player I found a sled that's in first picture. It's from a hitachi gd-7500. I don't know witch one is the IR and red diode. Also the sled in the second picture is from a combo dvd-cd-wr drive. I got out...

Hello to all of you nice people. Recently I discovered the magic of lasers and now I want to build one. Since I am from Romania and shipping would take too much I want to start today a build. I found only one shop that sells here Aixiz housing, and some diodes and a single driver model. I intend...
