I'm making a device to scare off moles. The idea is to have a vibrating component attached to a PVC pipe, which should amplify the vibrations, stick it in the ground and let it work its magic.
Right now I'm at the electronic part. I was thinking of an astable multivibrator which will drive a vibrator module I got from an old phone, with pots for pause and vibration duration control. Pic related
The transistors will be 2n3904, capacitors 1mF, R1 and R4 470 Ohm resistors, R2 a 1kOhm resistor and a 2.5MOhm trimmer pot in series, for pause duration control, and R3 again a 1kOhm resistor and a 15kOhm trimmer pot for vibration duration control.
Any reasons this wouldn't work? Any tips?
Also, what voltage should I power this with?
