OT: Blinding Bugs with a Laser Pointer

Some time ago it was discussed here to use a laser from an old DVD burner. I joked you could scan using a mirror assembly, and when you get a reflection increase power and burn the bug. Joked the experiment would leave all sorts of burning spots on the wall paper. Then a while ago I read somebody at NASA actually did it, and they can, from the reflection frequency, even determine what sort of bug is in the beam, and *only* shoot mosquitos that way... No it was not April 1, but hey, I did think of it first :-)

NASA reads this group?

Just waiting for someone with an odd shaped iris and his lawyer.

Well, it could be programmed to target lawyers I guess:-)

Neato..

I wonder if it'll become a pest control method.. For example.. A laser unit is placed on the floor, turned on and then it starts scanning for crawling bugs ...especially roaches. The scan height is low for low odds of blinding someone. When a roach has been detected, a deadly pulse is triggered.

If there's no misses then it might be possible there will be no damage to the baseboards (burnt spots) and low risk of setting the house on fire. :P

The amount of power to blind a bug should be orders of magnatude less than that which would cause baseboard burn spots.

You know those 10 million candlepower (or so they advertise) handheld spotlights you may have seen at CosCo or online? I got one, and one evening I shined it up near the tops of the trees and zeroed in on a flying moth. After a second or two it went into a tailspin and eventually flew into the ground. I did another, and another, and another until I was finally convinced that the bright light was indeed corrupting their nav systems. And this was just a big flashlight from

50 feet away, so I'd imagine that a laser would do the same -- if you could hold it right on the bug for a bit.

I think a laser bug burner would be more effective pest control than bug blinder. Roaches have very good odor receptors and iirc that is the primary way roaches find food. iirc.. roaches don't have much use for eyes.

I vote for bug burner instead of bug blinder.

And if someone managed to walk between the laser and the bug at the wrong time?

It'll be very improbable to get a bare foot in the firing line by accident.

Maybe in the fine print it can say: The Floor Scan anti-bug laser system would have to be respected like a spring mousetrap. 'Don't stick your finger in the mousetrap!'

I think it'll be doable to have firmware that can differentiate between little bugs and big feet. (The scan laser only gets a power pulse (turns into a 'death beam') when the firmware calculates a roach size and movement.)

D from BC wrote in news: snipped-for-privacy@4ax.com:

roaches have antennas that are very sensitive to air current changes,move fast,and are pretty tough bugs. You ever see a Palmetto bug? It's a LARGE cockroach,about 1.5-2" long,full grown. They fly,too. I don't think a laser would bother them unless it was capable of frying it in an instant.You'd have trouble keeping the spot on it for any length of time.

Found pic..

I think those are ones I saw in a movie. 'Bug'

Yes.. Some testing and ~debugging~ will be required. :)

A few beers and you'll forget you are sitting outside on your deck. That's not a fly, its a 747.

oops that bug pic link above is probably a giant water beetle.

Found another..

Tiny hands can make big bugs bigger.

For wasps and hornets, do the opposite. Attack them at night.

I was at one of those outdoor laser light shows (Stone Mountain I think)a long time ago. I could swear I could hear bugs getting sizzled near the laser equipment.

Hair spray is handy for just about any flying insect... even bees... quick shot and run... bee flies a few feet and seizes up ;-) ...Jim Thompson

Hair spray and a lighter is better; you don't have to run!

Mark L. Fergerson

That works for one bugger at a time. It's not a good idea to attack a nest with it. The instant death spray with a 20' range is a far better idea.
