    My First IR Build

    Got around to uploading my pictures, here's the de-canned 9mm 1W 808nm laser for those who are curious: First two pictures were taken with a 450D and 60mm macro, second two were taken with the 55-250mm zoomed in and the 18-55mm kit lens reversed and taped onto the end.

    ►CLOSED AMK GB◄ ~ SF-AW210 Diodes $10 Each

    Re: ►AMK GB◄ ~ SF-AW210 Diodes $10 Each I will commit for one sled (for batch 3 now, I assume), domestic shipping -> $12.50 total correct? Do I pay using the batch 2 payment link? I can pay as soon as this is all confirmed. I'm new to group buys.

    My First IR Build

    I just killed my 1W 808nm laser diode. De-canned it afterwards, I'll get pictures in a few days, I'm pretty sure I vaporized the bond wires. I put a big capacitor on my DDL driver, not thinking, then plugged the laser in (after the capacitor had charged to full voltage of course, since the...

    Strange green light from IR diode...

    If you've got a bunch of dichros, like I do from old cameras/cd drive sleds, you could try putting some in front of your camera and seeing if any of those block the IR light. I second the idea that this could be some other light generation from the chip. I don't really know much of anything...

    My First IR Build

    Same here, I've been keeping my eye on this thread/forum, but seems like there hasn't been much change. I've got one of those Ebay 1W 9mm diodes in an O-like module, and last night I tried renno's "2 aixiz lenses" technique, don't think it changed much and the focal point is way too close to the...

    Pulse Laser Rifle: Fiction-Theory-Reality?

    Well I just Googled "electrolaser", and actually came up with a link on this forum about it: http://laserpointerforums.com/f44/100kw-laser-1-000-000-000-volts-godly-weapon-electrolaser-44803.html No joke, 1 billion volts! And a 100kW laser! Definitely out of our reach by a huge margin. Here's...

    Pulse Laser Rifle: Fiction-Theory-Reality?

    Yeah, I imagine it would be pretty hard to tell whether or not it was working, I sure can't think of any way to measure the conductivity of an ionized air channel. I guess that's why the article quotes such ridiculously high voltages.

    Pulse Laser Rifle: Fiction-Theory-Reality?

    Well I was always just imagining that you would make 2 pulses, either by splitting that laser or using 2 lasers, kind of like how a taser shoots 2 leads. No grounding needed, as long as both beams hit the target, and as long as they're far enough apart that they don't just arc in front of the...

    Pulse Laser Rifle: Fiction-Theory-Reality?

    How ridiculous would it be to try to build one of these? Electrolaser - Wikipedia, the free encyclopedia Sounds like something that could do a fair bit of damage, and if we're talking about building a ruby laser, can't be much more outlandish than that, right? What sort of power and wavelenth...

    Magenta / cyan

    How about this: It can be done - White laser pointer I don't think you'd get much power from it, but it looks like it can make the 7 colors (and you might be able to make many more perceived colors by doing PWM mixing of the 3 lasers).
