What would be the Easiest and most efficient way to make this?
I need a circuit that has a switch between 3 and 5 minute off times and a 3-5 second on time that repeats. It needs ot ahve an on off switch and be as as efficient and compact as possibly, and fairly easy to make.
Thanks in advance for any help!
I need to order parts for it, so the parts I need would be nice.
