I don't think that's right. Just rather than one small spot in your pocket, or one small spot on your neck getting exposed to 2 mSv a larger area gets exposed to 2mSv. But, even if you jumped in a pool full of these marbles your body would still be experiencing 2 mSv

Re: 6x Blu-ray SLEDS GB! THEY ARE GOING FAST! Do some of us need a time-out in the corner for a while? It's way too easy to be a dick online, cause you aren't really in front of another person, so your emotions just sort of spew out ur finger tips onto the forum. I'm sure we've all been a...

Re: 405nm AR glass lenses - fit AixiZ  FEELER :D ahh, truer words have not been spoken

I grew up a lot, way back on the day I learned that light didn't really mix into a different wavelength.  It's all just a trick our minds play on us. It's so obvious now, but as a child, it really changed the way I saw the world. So much of the man made light we surround ourselves with is just...

I'm looking for a small momentary, pushbutton switch, like a tactile switch. I can't find any small switches that are rated for over 50ma. The laser is pulling at least 3x that. Can little tactile switches take more current than they are rated for?

Re: 405nm AR glass lenses - fit AixiZ  FEELER Hi, I want to mention again that I'll go w/ 2 of the lenses. I'm still on the list w/ a ?

Re: Turning laser on while the glow cap is on it.. yeah! flashlight/laser

diffraction onto a fluorescent or glowing surface.. that should show the invisible lines

My update doesn't change your suggestions that the diode is ok? In that case I'm guessing it's nothing easy to fix. The crystals look ok, as in they are clear and not cracked or anything, and rotating the diode doesn't make any difference. I'm pretty sure the crystal assembly is all glued into...

well..... I just took the back of the module out and exposed the diode. I didn't look into the diode but shined it on something. It made a faint red bar. I looked at the bar through my camera, and it wasn't much brighter than w/ the naked eye. (a remote control IR led shows up pretty bright...

I got one of the 50mw aixiz modules from ebay, and it doesn't work. They're sending a replacement, and their service is great! But, I don't think he wants this one back. It does not emit any green light, and while I was poking around on it, I noticed out of the corner of my eye a faint, deep...

I've had many blu-rays just stop working... I think most of us here have :)

Re: 6x Blu-ray SLEDS GB! GET EM WHILE THEY LAST Paid!  and I changed it to two..  my luck, I'll kill one on insertion -edit Noticed all 30 were already taken.. So, if you don't have any extras let me know and we'll work something out.. refund for one, or maybe I'll wait till batch 3 for the...

Your aquarium water is fluorescing a white/blue color, and that is what is breaking up into the rainbow.   I've got a 150mw b.r., and you can sort of see the beam, but when it goes through the aquarium water, the beam is intensely bright, light blue. I've got a big 240 gallon aquarium, and...

Re: 6x Blu-ray SLEDS GB! GET EM WHILE THEY LAST put me down for one please!

Yes, mine has the external adjustment bolts. I marked where I started, and made very small adjustments to each bolt. One at a time, both clockwise and counter, and see what gave me an increase in power. Then I'd put that back to starting position, and move to the 2nd bolt, then the 3rd. From...

I did align the mirrors when I got it. I got an ENORMOUS increase in power by doing it!! and a few more lines of color. the divergence of the beam however is not great. Then again, I don't think HENE's are that great either. I can get my pointer focused to a point 100 yards away.. the tube...

No, I don't want to burn things (I dont quite get the fascination after etching a line in plastic and popping a few balloons, lighting a smoke or 2... unless I can start a fire or cut through wood or something, whats the point). I want to be able to bounce the beam around my house, or simply...

My argon has no lens. The beam diverges, maybe an inch after 10 meters.. probably a little more. If I measure the divergence, is there a way to find a lens which will correct it? Then I guess the problem is finding a way to mount it. The laser just has a brass tube at the end. (Omnichrome, from...

Ive got those floaters BAD.. so do my parents.. Mom's going blind from glaucoma. bad news.. I guess I'll go look at my laser more while I still can! Really, I have no fear for my vision, so.. back on topic (Ive been tested.. so far at 32, still ok.. but the floaters do get very annoying when...
