I rested the laser spot all over the fly. A good 30 seconds.
I probably fried every light receptor.
The fly took off did a few chaotic circles in the air and I lost track
of it.
It did not reland on the ceiling.
I need more power! :P
1W laser fly zapper project???
With sniper scope of course :)
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.

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
>Neato..
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.)

>"Ouch... my retina!"

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.

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

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

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.
I cut a hole in the patio ceiling to install a speaker... immediately
inhabited by bee "scouts".
Called my exterminator service. He came, advised closing all doors,
including doggy door, 'cause, "I'm going to make 'em really mad" ;-)
They were completely gone in a few hours.
When I took out the toner cartridge, I saw the body of the roach
resting against the paper feed roller. Fortunately, the body had
been too big to go in. I took it out with a pair of tweezers and
placed it on the floor. I was amazed to see it still wriggling
and then walking on the stumps, albeit very slowly. I enjoy
killing roaches but making them suffer needlessly is another
thing. I quickly squashed it. Here's a picture:

ewwww..
imo..roaches seem to be non-existant in BC.
But we have giant slugs..

Even better - gasoline. Throw a half glass of gasoline on a wasp's nest
and they all drop straight to the ground. They don't even flap their
wings once.

Is that before or after you apply the lighted match?
On of the examples in Phil Hobbs' optics book was for a fictional (I
assume) laser bug zapper. IIRC it included a fully worked out flying
spot laser scanner to locate the bug.

A few years ago some local wasps made the mistake of setting up shop in
the external vent for our cooker extractor fan. Ready made ducting to
focus and contain the bug spray, perfect!

... and there are lots of newspaper reports of members of the public being
prosecuted, even imprisoned, for shining laser pointers at planes and
helicopters. An example is
http://www.kentnews.co.uk/kent-news/Police-helicopter-pilot-was-blinded-by-laser-pen-newsinkent24688.aspx?news=local
but the statement 'For the first time sky cops are using a device which
pinpoints the source of the beam and can photograph the operator' looks a
bit odd - perhaps it can only photograph the operator when he/she switches
the laser off and, obligingly, stands in the same position for a while. I
wonder if they're prosecuting people who use those torches with "the power
of a million candles" when they point them up to see what's making the
deafening noise above their house. Hmmm.

That's a good idea; throw gasoline on your house and light a match.
You're right, the bees will no longer be your problem.

Not when they're wasps and hornets, living in/on my house. I killed
as many carpenter bees as I could (and hired an exterminator to help)
last spring. I'm sure I'll be back at it again next spring.

Lasered grasshoppers vs accidentally blinded farmers.. mmmmm :|
And if things get too dry, crops might catch fire from lasered
grasshoppers?
Maybe a laser detect/laser burn bug system will do better in a
greenhouse.. Dunno..

Laser diodes are now powerful enough to kill bugs..
The question is: Can solid state lasers perform a pest control role?
Or at the very least be an amusing geek toy to sniper the occasional
house fly.
It's like firing a laser is like firing a gun..
I recollect Calcium Carbide being used to kill wasps - I presume it was the Acetylene, though as I was only 9 or 10 at the time
I cannot be 100% confident of this.
Might've been a similar product. I recall calcium phosphide has been sold
for killing moles and the like. Moisture causes it to release phosphine
("hydrogen phosphide" as it were), which bears a strong resemblance to your
above comment. Phosphide is a major impurity of carbide, which doesn't
really mean all that much (it could be parts per million, which would be
fairly pure actually), but because it's so poisonous and smelly, it's a
notable component of the stuff.

Unlikely - point it skywards or horizontal above the crop, and with
enough energy to fatally injure, not incinerate. Turn them into fertilizer.

More dangerous IMO due to reflections.
think of it from the police viewpoint;
a laser spot on their body could be a GUN-mounted laser,and thus a deadly
threat.
from the pilot's viewpoint;
trying to fly (to keep the AC in the air)after being blinded is rather
difficult.Thus a lethal threat.
ISTR a few people in the US being prosecuted for shining laser pointers on
aircraft,IIRC,police helos that were hovering in the area.
(BLACK helicopters,too,BTW!!)

Bees aren't wasps or hornets. If he meant wasps and hornets, why isn't
that what he said?
