Not from the effect of the laser, but possible the cell damage from a burn could cause cancer someday, any cell damage would be suspect to cause abnormal cell function. It is not likely but you do not have to have ionizing radiation give you cancer. Though I suspect most cancer comes from a mix...

Re: Laser to deter neighbors security camera! I would suggest asking him not to point it at your property, as nice as you can. You would be surprised what asking nicely can do. That failing, you can use a lens and some of them led and driver combo dtr pulls out of crapios. Call it a red...

Yes, if you cannot see a table because your blind, can you stub your foot. First part out the way. Virtual particles can be measured, so they are real. Now if it was in a different dimension It depends on the way you mean the word, I would say yes, if it exists at all then it exists.

fyi not sure about your dye but, I have used a 300mw 405nm bluray laser with the lens removed, to replace a uv dye lamp for checking for leaks in an hvac system and I can tell you it worked like a charm in my case. Also I can add that the laser goggles adds to the visibility of the dye. It may...

Any way I was just showing that the mix of salts and other compounds change the conductivity of the water, and over time unlike table salt, most do not mix well and sink into the water, making your reading on a dmm go wonky. If you shake the bowl up, the reading should stabilize then drop slowly...

LOL at people who have no idea what they are doing, I was a commo guy 11 years and a avionics tech for 6 I have no clue what I am doing. I got it to work, I could make it work over and over again, just think of it as a survival technique, and not every one carries resistors in their pocket...

It all depends, I can honestly say I have had to use that method and I did get it to work. I hit a station 60 miles away on a 16 mile radio by making a field expedient long wire. Hard to find a radio shack in the middle of no where. The electrolyte solution will not spill or leak unless you make...

What no one has made an impromptu resistor for a custom antenna out of a small container salt and water? Visine bottles and ear plug cases work well. They add salts to water in to help soften it and whatnot, after it rains, my tap tastes like dirt, some of the sediment is conductive in water and...

Thanks once again you two. Have to go back to the post it note and revise my idea. :P

A better way to ask would be if I use signal, that is a the freq of a known microwave emission's harmonic, can they interfere?, and usable data be taken from interference.

Could you use a harmonic of a microwave freq, in visible light, to cause beat interference. Eg, using a known peak wavelength of microwave of very low power and a laser at very close not not exact f4 harmonic to set up a beat wave patterns. Then use the pattern to gain information about the...

Not sure about disabling a motion sensor with a laser, seems like it would open the door. However they have a switch to turn off the auto door feature usually on top the door. Not all that high tec but perhaps it would work for ya. Also don't get the shop owner or yourself sued.

Hmm assuming, your eyes and my eyes are close. A conservatively driven PL450b would be around 150mw. At 150mw indoors the 5mw green is 2.55% less bright than the 150mw 450nm. Outside at night, I do not have the hard data but the 450nm at 150mw "should be around" 3.25x brighter than the 5mw 532...

No but I do know quite a bit about avionics, night vision and FLIR. I also know all of them 747 pilots go through training that allows them to land by instruments alone, and I also know that a floodlight aimed at a jet could do the same thing as a laser, at close range, IE landing or taking off...

Well instead of making new laws to be honest, perhaps they should make new aircraft laser proof. I sometimes wonder as intelligence rises and technology increase how indeed they will feel safe when an average everyday guy can macgyver up a death ray or a salted fusion bomb. Screw I will be too...
