Hi.
Can a sawed-off slot type optointerrupter, of the fax paper detection type (5V logic output) turn on/off a mosfet for making a dusk-to-dawn 12V switch ?
The sensing half to drive the mosfet gate. Partial turn-on undesired, that is why the logic output type.
[Trying to do it the simplest possible way only with these parts in my bins. Beefy mosfets salvaged from PC switching power supplies; optointerrupters from fax machines]
Considerations ?
