Hi to all . I need some help, I had seen a circuit sometime back which I thought could serve my purpose , but has been unable to find it. What I need is to build a variable time delay circuit to operate a 110 volt relay . This would serve to apply power to a fridge with a delay of up to four mins after power has been restored, the timer has to work off 110 v maybe thru a small transformer if necessary. Thankalim.s for your help.
