    Ideas for exposed LDs?

    Thanks Daedal, and Gazoo. Now you guys have me put on the spot, lol. If I kill this diode... it will be a very sad day, but considering I've got Daedal's driver, which so far had been very, very stable, I probably won't be killing anything for a little while. I'll probably get the driver off the...

    Ideas for exposed LDs?

    I used the diode test on my Multimeter to find which leg to connect to. Then I soldered leads to them (helping hands are amazing, I bought them to use for all this close up soldering with the LDs, and now I don't know how I lived without them! Daedal, you should really get some!). Then I...

    Bag of Optical components (BIG pics)

    Bootleg2go, It sounds like your kit is a way better deal. To be honest, I just got that kit as a Christmas present, and didn't know what the price of it was. I thought the kit was pretty cool, but you're right, it is overpriced. Where can I get your kit bootleg2go? It sounds like a really sweet...

    Ideas for exposed LDs?

    Forgive my ignorance, but is a TEC a Thermo-Electric Couple, like a Peltier cooling device? In a related question... where do you guys get thermal epoxy from? My radio shack doesn't carry it anymore, and that was the only place I could think of that would have it. And Daedal, you were right...

    Ideas for exposed LDs?

    Last one, this is just the pins. This diode happened to just have two pins. I think it was the IR one that had the 4 pins, with two not being used.

    Ideas for exposed LDs?

    Here, a close up, of the last image, full pixels croped from the original image (i.e. it's not been resized, just cropped). This is what I'm pretty sure is just the diode material.

    Ideas for exposed LDs?

    Like I promised. Here are some macros of my diode. I'll post different angles of the diode, so that it might help the curiousity of some to see this thing up close. This is the top view.

    Ideas for exposed LDs?

    Daedal, I forgot to mention that in my photo my LD was lasing. I had it at about 180 mA in that one. It melted eletric tape when I held it in front of the diode. Is there any way to regulate the voltage going to the diode? My circuit keeps putting out about 4 V when I'm using 4 NiMh batteries as...

    Ideas for exposed LDs?

    Gazoo, here's what I bought off eBay, the whole thing was $21.50 shipped, so I figure it was a pretty sweet deal, especially for 2 diodes, optics, and some motors. The model is a Samsung DVD Writer Model TS-H652, it was 18x, or at least that's what it claimed. I'll try to get some macro shots of...

    Bag of Optical components (BIG pics)

    I got some optics things from Edmund awhile back (before I was into lasers, just into cameras back then). I think the white edged stuff is some cheap diffraction grating, as I got the same thing, and it diffracts, but it's not as good as some others I've seen. As for the optics in the bag, mine...

    NEW Group buy for Sony 16X dvd burner diodes...

    Re: NEW Group buy for Sony 16X dvd burner diodes.. I get paid on Friday, depending on how much I get I might be in for a few. Thanks again SenKat for putting in the effort to help all of us here. I'll send you an email once I get my pay check.

    Ideas for exposed LDs?

    Thanks Gazoo, I'd love to see how you put the diodes in the modules... cuz I can't think of any effective ways of doing it.... Right now I've managed to get the driver board partly assembled. It's putting out more volts than I'd like, but I'm keeping the mA low. It's about 180 mA most times...

    DIY Homemade laser diode driver

    Great driver circuit Daedal! I've got some questions though. Is there a way to use an LED in place of the 1N4001, or some other place so that I could be sure the driver is sending current through the LED (in case this were to be used on an IR laser, I'd want to know the laser is indeed on :o)...

    Ideas for exposed LDs?

    Thanks SenKat and Daedal! Daedal, I just found your driver today, and I've been trying to read it in bits (lately, I've been working a lot, we have a new manager, and she had the idea that it'd be wonderful to work everyone their max availbility... I've been working 39 hours a week at a job...

    Ideas for exposed LDs?

    Sorry about the large pic ^, I keep forgetting about my camera being 7 MP... Anyway, I got some time, so I took some pics of my LD and my tube, First the LD! Sorry the pics are in IR... it's the camera that is easiest for me to take quick macros with...

    Ideas for exposed LDs?

    I've been busy working lately, so I only get to work on my lasers in the wee-hours of the morning... I got one drive, and sure enough, I screwed up the laser, at least as far as I can tell. When I first got the diodes out, I kept getting mixed up on which one was the IR and which was the Red...

    Intel's Silicon Hybrid Laser

    I saw this on HowStuffWorks, and thought I'd share it. To some here, it might not mean much, to other's, it might be a "Wow, that's kinda cool...when can I get my silicon hybrid laser." But mostly, I thought I'd just share this knowledge. These guys sure do rattle off their chemistry words fast...
