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>
<div><br>
</div>
<div>Even if the Squirrels steal it.</div>

I think the idea is to keep it charged
so that it does its work on<br>
contact.<br>

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>
