DIY HACK – Deer Repellent
Here’s a cool Deer Repellent for those of you with deers on your front yard that eat up your plants. But just turn it off on Christmas so Rudolph the Raindeer doesn’t get scared.
My original “Deer Repellent/ Seismic Sensor” recommended using a speaker with a weight glued to the cone as a vibration sensor (see bottom of page) but it recently occurred to me that the speaker could supply the mass itself. By gluing a standoff to the center of the cone, an inexpensive 2″, 8 ohm speaker becomes a vibration sensor with a natural resonance below 100Hz which is quite good.
