Hello guys,
I've just built this LED blinking circuit and it works wonderfully. What I'm looking to do is instead of connecting an LED I instead have the output hooked up to a relay coil. The problem comes because this circuit outputs a blinking 9v signal and the relay coil requires 12v. I'm hoping that there is some way to hook up a transistor to the blinking circuit running on 9v to then switch on and off the relay circuit running off 12 volts, with two seperate power supplies. Would this be possible?
Thanks,
