Any idea what this is worth?? All I can tell from the pics is that its a "Uniphase SLM-Green laser". 532nm 125mw. Does anyone know what the big box is? power supply? something for holography? It's for sale close to me for 195$ but I don't know what its worth. Any help would be appreciated! 1...

I made a pcb and laid it out pretty well in eagle. Pics below. Would anyone consider doing some of this for me, I cannot make the traces bigger, or else I run into clearance problems with my small tps chip. I like how woop and some people do the whole board copper and just etch out little...

Selling PHR-803T Sleds with the high powered blu-ray diode in them. http://www.thesellgrens.com/sale/index.html

Alright I finally sat down and did this. Let me know what you think or if you see any problems or areas to improve. Thanks! With those value resistors, it should be ABOUT 60 mA to 410 mA.

Alright, many people in this community have helped me so I am giving back and doing a writeup on how to harvest a diode from a pioneer-115d DVD drive which can be found here: http://www.newegg.com/Product/Product.aspx?Item=N82E16827129018 There is also a 17$ deal going on on "open-box" drives...

All Gone!  :D :D :D :D ;D ;D ;D ;D :P :P :) Sorry for the slight price increase. Many costs were factored in and it was what I thought was acceptable. Please do not post about it. I had to factor in shipping costs, wire transfer costs, packaging costs, gas trips to post office, my time, and...

Hey all, I'm currently in contact with a distributor that may be able to get us some phr-803t sleds. For around 25-30 dollars. Thats what they said for a min order of 10, but I know more than 10 will be bought so I can try to haggle them down more. They speak only chinese, with horrible...

So here it is! I'll probably be putting a 115D red in it, or a 803t if anyone would be nice enough to sell me one... i had a drive way early and then that Chinese mofo sun jum kin lee or whatever told me he was out! Argh! Anyways, it used to be a LED flashlight. It has a twist on, and a push...

What are my options for lenses? All I see is the aixiz acrylic or glass, or a merideth. I just need the little metal enclosure, and the lens, so that I can put my diode in it and make a heat sink for it. Can someone give me a summary of the different lenses, and their size or use. I know their...

I asked some questions but decided to start a thread here. I looked into a few components. I was thinking: 1: use a dc dc converter to up voltage(if you started with one or two AA's) and then use that higher voltage to run a constant current regulation circuit. But I was talking to my dad and...

am i confused or is this the long open can red diode we have all come to love? newegg dot com/Product/Product.aspx?Item=N82E16827118004

haha I'm probably fine but just want to know whats up or if this is all in my head or because I've been on the computer for way too long. So I was bored and took my first diode out of a cd-rw drive, knowing it would be IR i set up my video camera on night vision mode to see it and hooked it up...
