I would like to enable power to a regulator from a 1Vpp guitar pickup. Threshold can be between 0.2V and 1V. And I need it to disable after about 60 seconds of no signal from the pickups.
I'm considering using a Schmitt trigger and a RC circuit add the delay for disabling the regulator. I need to increase RC to get 60 seconds and change the schmitt trigger specs from my schematic.
Does anyone know of a better way to accomplish this?
