Ooh, after hearing Aaron's suggestion about a laser (in the ultrasonic sensor thread). Why not use some cheap 1W laser diodes off ebay, make an arrangement that covers the opening so they have to fly through the beam. Would allow them to pass through unlike a mesh/screen and might be easier to catch them with (plus will allow the dead to fall out easier since no physical mesh there). Might need a few diodes but you can get like 50 packs for $20 on ebay from china lol...<div>

You don't need to detect them at all...<br>
Just use two parallel meshes at a distance of about 3/4 the length
of a yellow jacket...<br>
With opposing charges on the meshes, the yellow jackets become the
trigger... <br>
<br>
This is not uncommon in Korea for mosquitoes...<br>

Hi Richard,
<div><br>
<div>
<div>Thanks for the note.</div>
<div><br>
</div>
<div>I figured keeping a coil charged might be
expensive on the batteries. Seems the next
place to go is keeping a capacitor charged.
As I mentioned in the blog post, a
disposable camera may have enough hardware
to do this. May not be as high a voltage but
it might work. </div>
<div><br>
</div>
<div>So it just comes down to triggering the
high voltage thing. </div>
<div><br>
</div>
<div>I'm all ears on how to trigger it but I
figured I could just use an arduino because
the labor content may be lower. There might
be something that can save some pennies but
I think for the pain a community of yellow
jackets causes, it's okay if it uses an
arduino for a couple days.</div>

Does it really need an arduino, or just
a wired power supply and a way<br>
of forcing all entering and exiting
wasps of touching the charged wires?<br>

I've seen one of those at a friend's
cottage. It is only $10, so it<br>
might be worth just buying one to find
out how it works and adapt it for<br>
automatic use with your wasp nest. We
had one in the floor of our<br>
balcony. It was a nuisance...<br>
<br>
You might want to adapt it with very
fine wires brushing around the hole<br>
(but if the wire is too fine, it might
fuse instead of delivering the<br>
intended shock to an insect...)<br>
