I baught this laser from DX about a year ago rated at 20mW. It really is a great pointer. It is the one I carry around with me. Now that DX sells modules you can do what I did and put their 200mW module inside of it. Mine has a threaded retaining ring for the module. I just had to put some...

Infrared lasers are somewhat more dangerous than other coloured lasers because if you do accidentally flash yourself in the eye, you won't have the natural blink reflex that you would have if you could see the light. If it is a 5mW infrared laser, this isn't as much of an issue. Anything higher...

I got that HeNe tube fired up this morning. It works great. Thanks again Dave for telling me about the tube and PSU acting as capacitors. I didn't know about that and you saved me from shocking myself. You really are an asset to this forum. Steve

Can you do a label as 808nm rated at 1W in that grey colour? Thanks Steve

If anyone is interested, I am willing to trade a Visene bottle(15ml.) for 2 cubic centimeters of gallium, or sell it for $20 plus shipping.

I found this today and found it to be quite helpful to any one working on a Helium Neon Laser project. Meredith Instruments - About HeNe Lasers - The Source for Lasers, Mirrors, Optics, Parts, and Surplus

I'll buy one of the 2-3mW ones for $15 shipping included.

I have a 150mW+ module in one of these. It looks cool, feels solid, and it's heavy. It's made of brass, with chrome over top. It has a 12mm bore so it will provide decent heatsinking also. It is also very easy change out the module. It has a threaded retaining ring to hold the module in place...

Thanks to everyone that gave me offers. I have purchased one, and I'm sure I will be happy with it. Peace Steve

Hey Laser_Ben. You totally ripped me off. I've been waiting for my 3mW HeNe laser tube for over 3 months. I've tried to get you to refund my money and you won't respond to my PMs, E-mails or the PayPal invoice I sent you for the refund. YOU HAVE NO BUSINESS IN A THREAD LIKE THIS!!! I baught...

Hey DJZ, Can the optics be re-aligned or is the laser permanently ruined? If it is just a neon lamp now and can't be repaired, than it's probably not worth the shipping cost. That would be an awesome laser though-Green HeNe. If I'm not mistaken, the desklamp that Dave built has a green HeNe...

Dave, Good to have you back. Does that tube need 8-14kV or is it .8 to 1.4kV? The brick PSU that I got from Chris(Heru) is rated at 1400V (1.4kV). Also I live across the river from Detroit in Windsor, Ontario, Canada, so how much of an increase in shipping? Also, off-topic: Did you get that...

Those are nice lasers; but they're about $100 past my price range. I was hoping for something out of an old grocery store scanner or a de-commissioned medical laser machine. I baught a complete HeNe laser for about $50 a while ago but the tube is not exposed. It is siliconed inside a metal...

I'm looking to get a small bare HeNe laser tube for a desk lamp I've been trying to build for months. I baught and paid for one from Laser_Ben over 3 months ago, but he ripped me off-kept the money, didn't send one, and won't respond to my PMs or me billing him for a refund on PayPal. I have...

No one wanted to take over the GB, and I've never done one so there isn't one. Feel free to go ahead and start one if you want. Susie at O-Like was the proposed supplier. She said she needed a minimum order of 200 pieces at 12.50 each. I only want a couple, so it really isn't worth my trouble...

I'm in too! Portable near IR 808nm 951mW max and settled at 945mW average on a used battery. It's my cigarette lighter/engraver.

Where that jumper is, is a perfect spot for a 6 x 3 mm tactile switch. With this driver you could make a keychain blue ray pointer... if it will actually run off of 4.5 volts.

I have a laser just like it that I baught from DX for $24.(20mW) Later on I got bored with it and baught a supposedly 200mW DX pen laser and put that module into the bottle type host. It works great. So it is possible. Up to spec?... Maybe, but not likely.

My first flash drive costed my wife $175 and it was only 128Mb. You can't even find one that small now.

First off, I wanted to get it out of that house. It causes cancer. Second of all, it's really cool to look at. Didn't you see Terminator 2 ???
