get a wicked lasers Arctic or dragonlasers spartan. +-1w of nice pretty blue 445 for a few hundred bucks. thats a great start for a RESPONSIBLE beginner.

It's a little better today it's kinda weird seeing in greytone in that part of my eye. I didn't think there was much that could be done anyway. I have had weldburn before and that felt like sand in my eyes but this is a lot different

It was my Arctic and the included glasses that this happened with.

I got flashed pretty good with 445 blue and am seeing grey in my right eye. I was wearing glasses but it was still a pretty good reflection.

To me the dot looks almost white with the naked eye but I do sense violet undertones too.

If I remember the laptop was a HP. These do in fact have 6 vent holes and a melted marking with "IO3A" stamped into them. They do power my Arctic very well, but I did end up throwing away 3 of them just because they read lower than 2 volts. I guess they may have been good but why take the...

looks like crazy jay hijacked my thread.

Well I checked the voltage with my Fluke meter and it would seem that the cells that read the lower voltage were the cause of the diminished capacity. These cells had a pinkish read sheath and a red top.

well the ones that were above 3v were spectacular so far and I will play with the others to see what I can get out of them. What do you think the amh rating is on them?

I checked them with a voltmeter! There were 2 cells that read 3.4v. 2 cells were at 2.8v, 2 were at 2.4v and the last 2 were at 1.8v. The two that read 1.8v I don't even think I will attempt to try and charge.

I pulled apart one of my laptop batteries last night and got 8 18650 batteries from it. They have a pinkish red coating and have several markings. HLUFJT6 and also IO3A They are also a little bit heavier than the cell that came with my Arctic. I put one of them in my charger and am also...

you all know I am kidding with that one right... I am starting to think I would be better served by like you said building a few simple handheld pointers to get the hang of things first before I try to start WW3 in my backyard.lol

I could buy a generic 100w co2 tube off ebay for about a grand and hook up a neon light transformer and window washer pump to circulate to circulate water thru the cooling jacket. Then get one of those ktp thingys so we can see the beam. All I would have to do then is figure out how to mount the...

thanks bro!

like I said really sorry for asking what you guys consider really stupid questions. I have been combing through the stickies and sometimes it's hard to find exactly what I am looking for. How much power does it take to cut steel? I know it makes a difference how thick it is and what type of steel?

thanks bee.. I have been searching on portable laser drivers but still havn't found a breakdown on the circuitry yet. I do HVAC for a living and usually we have printed schematics on wiring and logics.

whats a yov4 and a ktp crystal?

that would be #24 1 watt diodes all targeting one spot right? that is pretty wicked but you couldn't send that beam in another direction could you? and queme 808 would be a very deep red right? why when you change wavelength does the power drop?

By visible I did mean below the IR wavelength. I did have a GCP-2 a few years ago which was a rifle mounted Mil-spec ground commanders pointer, focusable @100mw, it was IR and the beam was spectacular with my night vision goggles. But building something, I would like a visible wavelength...

Holy dog doo! Do you think I could just create a stable wormhole allowing me to travel to millions of different planets instantaniously! Reconnect the ZPM Rodney! The CR123's are overloading the power conduits.
