Well so far my critter ridder deer repellant seems to work Need to get the Mosfets instead of using transistors. The base resistors get hot quick.
Now another pest (BATS) in church steeple.
Planning on using a pic that outputs varying frequencies but driving the tweeter.
Don't need much of an amp and beside this unit will be running 24/7 so the push pull amp will surly get warm?
how to safely power a tweeter using the pic output.
Thought about using just a 555 but want the variying frequiencies.
maybe just a 2n2222 on output?
The schematic with two transistors, I will only be using one
The mosfet amp I think is before reversing the mosfet input from Vdd.
Hopefully the one 2n2222 will work. Inserting a resistor to limit current as the piezo tweeter has no resistance?
any suggestions
