Has anyone ever tried to hack one of these?

Cordless Pest Repeller

Trademark Cordless Ultrasonic Pest Repeller - Covers 5000 Square Feet
Kmart Item# 010V002692085000 | Model# 82-5028

This product is available through a Sears distributor. $24.99

It might have some use as a triggered audio player. Looks like a large built in speaker. I'll bet with slight modification you could wire an audio plug to have it play the audio off a cheap player whenever someone approaches. The price is about what HD charges for a light sensor.

Regardless of the hack...I could use one of these to shoo off skeeters when I'm prop building outside in the evenings. 5,000 sq ft range?....hmmm.

Never seen one so I can't say for sure, but it's doubtful you'd have much luck trying to hack it. My best guess is that it's a high frequency oscillator driving a piezo element. Even if it does have a conventional amplifier circuit in it, the piezo wouldn't reproduce the frequencies you'd want it to.

I'm assuming its only for the insect variety. I need something to shoe off squirrels and chipmunks, they keep chewing at one of my pumpkins that are out. And before anyone suggests pepper, I coated all three with Blaire's Ultra Death Sauce but doesn't stay for long.

Good point!

Of course with my ears it'd have to be loud enough to break glass...
