Thanks for the note.
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.
So it just comes down to triggering the high voltage thing.
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.
Even if the Squirrels steal it.
