Re: What is a 2mW HeNe tube worth? Normal power supply won't work. HeNe tubes (depending on power) need a couple kilovolts at low current to operate.

Deal Extreme.

Re: Dragonlasers 10X Beam Expander No. They go over the front of the laser.

Because using them in public without a variance and the safety features is illegal. Plus cops can kind of do whatever they want.

Building and owning a laser without the FDA safety features is legal in the United States of America. Importing one without said safety features, or selling one without said safety features, however, is quite illegal, yes.

That's why I didn't say I was 100% sure. ;)

Green rechargeable CR2s are 3.7V. DX sells the same ones. (99.99999997% Sure these are 3.7V)

Even on the surplus market, heads like that sell for over a thousand dollars easily.

Is it a plasma cutter tip? Edit: *shakes fist at Trevor*

Re: FS: All my laser goodies. Because the case has scratches on it and a crooked hole? :thinking:

Re: FS: All my laser goodies. The sensor is fine as you can see in the photographs, the box is the only thing scratched, so I don't see how it's 'highly' damaged.

Re: FS: All my laser goodies. This is basically a Kenometer Pro, but with a thermopile capable of handling 10W of laser power all in one box, you realize that right?

I believe he lowered his price $15 to $70.

Re: Kryton groove duty cycle @1A That's what was happening with Mario's switches as well. I don't think there are any other 16mm switches out there that work. You could try one of the switches from Light Hound designed for the Surefire lights, but they're like $10-12 a piece.

Re: Kryton groove duty cycle @1A It's not the spring, people have put plenty of current through them before, remember they weren't designed for laser hosts, they were designed for flashlights. Try shortening the spring, I bet you it's shorting to the side of the host. MarioMaster was having the...

He's talking about how the OP wrote and drew stuff with his laser. He used long exposure settings on his camera and moved the laser around quickly.

The bond wires are only designed to take 500mA. The die looks somewhat alright, amazingly :na:, so if you can get that solder out of there and the other bond wires aren't gone, it may be salvageable.

It didn't really go COD though, it just melted the bondwires. @OP, try taking off the rest of the can as carefully as you can, it'll make resoldering those wires easier. The pedestal the die is mounted on is brass I believe.

Kind of the opposite. A milliwatt of energy is a milliwatt of energy, so 100mW of 532nm laser light will have just as much energy as 100mW of 660nm laser light. The burning factor comes into play with wavelength absorption. Shorter wavelengths are absorbed more easily than longer wavelengths...

Get a waterproof light, a net on a long stick, a snorkel, and hop in :eg: In all seriousness, that stinks :undecided:
