    Green Laser Scanning Photo

    I thought this was interesting because it makes it seem like it's possible to render a 3-D object onto a 2-D media while still showing all sides. I've seen this done using the CCD from scanners, but I didn't expect the laser to create this kind of an image. I thought it was kind of interesting...

    Green Laser Scanning Photo

    Sorry I've been missing for awhile. I've got some cool photos to show when I get the time to scan them. I took this one the other night of my brother, and I thought you all would appreciate it. Basically, what I did was used a line generating diffraction grating on a DX 50 mW and had my brother...

    ThermoElectric Coolers (TECs)

    My TEC Arrive in the mail today! It freezes water, and it boils it too... It also seems like it melted the solder on the top... cuz when I put water on it, it kinda changed the shape of the top of it... it still works great though. I wasn't even sending 5 Volts through it, I didn't check it's...

    ThermoElectric Coolers (TECs)

    I got one, it was at 9 units when I bought one, so it's probably at 8 now, unless someone else jumped on the band wagon ;D I guess I need to get me some Artic Silver Epoxy now... I've got Artic silver thermal paste... so I guess I play around with the pelt and the laser while I'm waiting for...

    ThermoElectric Coolers (TECs)

    Gazoo, that is AWESOME! Quite the heat sink for the laser. I'm impressed. I'm going to be ordering my TECs in a few days, maybe I'll grab a cheap CPU heat sink while I'm at it. Thanks for showing us your setup. So how well does the laser work with that heat sink attached to it? Is that the LM317...

    ThermoElectric Coolers (TECs)

    Psuedo, it sounds like you might have what I'm looking for. To be honest, I don't know anything about TECS, beyond the basic ideas of apply voltage, make sure there's a heat sink on the hot side, and make a thermal connection to the cold side and what needs cooling. Beyond that, I know nothing...

    ThermoElectric Coolers (TECs)

    That's a pretty good way to look at it Evilution. I hadn't thought of that (seems pretty obvious in hind-sight though, lol). It might also run off 5 V though... I could probably just hook up the motherboard to a power supply, and see what it does. It seems to work on 2.4 V, Water at least will...

    ThermoElectric Coolers (TECs)

    I found a link that's pretty cool, or at least seems pretty cool to me. I was looking up TECs mostly to find a good deal on them, and to see what was out there. I saw some that had holes in them, and I thought "What the heck are the holes for..." and to my utter surprise, they're for Laser...

    What about a group buy for a nice @ 125Mw Greenie

    Re: What about a group buy for a nice @ 125Mw Gree That really is sad Psuedo... but I guess that's the nature of the beast. The thing I'm curious about is the red lasers from Newwish... why doesn't DX offer 100 mw Reds? Curse US Customs... they make group buys for fun stuff no good for us...

    ThermoElectric Coolers (TECs)

    Daedal, conviently the TECs leads are correct. The heat sink gets hot and the copper part (which used to have some thermal compound on it from where it attached to a G4 processor (I think it was a G4, might have been a G3 processor...) I'm having difficulty writing this post because I'm watching...

    ThermoElectric Coolers (TECs)

    I noticed that there was some talk about TECs on another thread, so I thought I might start this one in hopes of creating a resource on the topic. I personally know very little about them, but I'm sure that others here do know a great deal. Here's my TEC I got off an older computer. If anyone...

    What about a group buy for a nice @ 125Mw Greenie

    Re: What about a group buy for a nice @ 125Mw Gree Hey Larry, you've got a good idea there, and I found a link that might be of some use to you. Granted, the lasers are probably bad IR leakers, cuz they seem to be the same ones DX orders, but there's the possibility that ordering them as a...

    Ideas for exposed LDs?

    Awesome work guys. I found a TEC I had, I got it from an older Mac (it doesn't surprise me to find a TEC for a Diode inside something from Apple from years ago, but the heat-sink is way too small for any decent type of thermal pumping...) I was wondering if anyone knew anything about the DIY...

    hand held projector :)

    That's awesome! I love the 6th picture, the shape made is just amazing! And with a 5 mw no less! Very cool. What kind of control do you have over the motors, I noticed what looks like a pot on a board in one of the pics, are there two pots on the device? And, if you don't mind my asking, where...

    Ebay Laser Goggles

    I bit the bullet, and bought some of the 650 shades from WL, and some of the sports Elite for my green lasers.... That looks like all my last paycheck is going to afford me to spend on fun toys (and retinal protection from them ;D). Thanks for all the help. It's too bad IR goggles are so...

    Ebay Laser Goggles

    Thanks SenKat, I wanted to be sure that it was too good to be true, and as things with lasers (and most things) they tend to be scams... So are Wicked Lasers and Nova the only places where getting goggles is safe? I haven't dealt with either company, but WL seems less than fun to deal with...

    Ebay Laser Goggles

    So I found this today, and I want to know what everyone thinks about it. The green ones seem like they'd be awesome, since they block 532nm and 1064 nm (so it'd be Perfect for playing with a DX 200 mW). And they seem cheaper than WL or Nova's goggles. Plus they look pretty slick too...

    DealExtreme

    DX sure does have great deals, it's just too bad it takes forever to get the stuff from them. I ordered two sets of items from them, and I've got most of the stuff in, I'm just missing some light up toys, and one of the new cheaper 50 mw greens... it never arrived, I was hoping I'd be able to...

    Ideas for exposed LDs?

    I have no intention of making this thing a portable pen laser ;D I'd like to, but it looks like to keep this little monster happy, I'll have to pamper it, and give it lots of juice, and lots of air conditioning...(sorry for the metaphors :P). Just as an update I've been playing with it at 330...
