I've found after several
generations of these mechanical deer deterrents that sometimes a smaller sound can have more of an impact
than a more steady, louder crash.
I'm pretty sure deer have
excellent hearing, which should mean they
would be alarmed at any unnatural sound. I've even noticed how the
sound of a chain saw doesn't seem to push their alarm buttons.
This set up allows for
several variations which helps to prevent a
situation where the enemy might become accustomed to the deterrent.
Stay tuned for more details
on a low budget delay circuit. I'm still
working out the details, but ideally it will have an adjustment knob
where the delay interval can be set to a wide variety of choices.
