Laser Pointers - Green, Red, Blue Lasers at Laserpointerpro.com (at the bottom) Blue Light Hazard (near the middle) More here: https://www.google.com/search?q=blue+laser+cancer Apparently it also kills cancer in addition to causing it, much like radiation and chemotherapy. It looks to me that...

Yes I did, and it took until now for someone (me) to come along with the answer the original poster was looking for. Incidentally, I found this thread via Google while looking for an answer to the same question. Now that I've posted it, anyone else coming here will find what they wanted to know.

These are ready to go down to 20 meters or 40 meters, depending on the model: Beamshot Tactical GreenBeam Waterproof Laser Pointer FREE S&H GB50, GB100. Beamshot Laser Sights. By the way, don't point the blue lasers at your skin. They can cause skin cancer. Most of the lasers discussed on this...

Re: FS: DIY Light Sabre Massive Custom Mace of Doom 2.0 w/ 2 Focus Knobs 2x18650 $125 Too bad all the extra aluminum isn't black anodized. It would look really "polished" then.

Time warp? Powers?

Yes, mixed metals can corrode each other in a galvanic reaction, but that's not what I'm talking about when I warn you against mixing gallium and or mercury with aluminum. Within seconds, your aluminum will crumble to dust with the mercury. Within minutes, your aluminum will be as fragile as...

The only reason you would need to do that is for corrosion resistance in a steel radiator. If you use copper, you don't need to worry about corrosion as long as you use distilled water and acid-clean copper. If you can't do that, then use phosphor bronze instead of copper. Phosphor bronze should...

You don't need a radiator or a pump. Put some BB's or a marble in with the water shroud, and all you have to do is shake the device to circulate the water faster than convection does it. If you want to go more advanced, solder some copper wool to the inner surface of your shroud, and you'll...

Heat pipes are the best conductors. But, I think a shroud of water would do just fine for both heat sinking and "conduction". Water doesn't conduct so great, but it does naturally convect, with no need for a pump. It's like a heat pipe, but cheaper. The problem with trying to disperse the heat...

Water is the best heat sink there is. It's better than aluminum, better than copper, better than silver. There's no need for pumping, just figure out how to put a water shroud around your diode heat sink, and off you go. It'll absorb more energy than anything else.

Have you noticed anything REALLY unusual? Like, you know...........powers?

Re: 1.4W+ 445nm Survival Laser SL-1.4 Only $199 Shipped in US Did you get my PM?

This is a beautiful instrument. What is the life expectancy of the diode? What is the recommended duty cycle?
