I posted a thread earlier for a cooler timer and got some good suggestions, but the ic is not available at our local stores. so i was thinking if the circuit could be made of only of 555 timer. what i think is using 2 timers of 4 min each such that when one is on other is off. From the outputs of both; one 555 would be used monostable for 3 min. when one timer would be on then after 3 min the monostable will start a motor and stop it after timer goes off. then from the other timer again the 555 would be activated after 3 min. and again start a motor through a relay. but i doubt whether a single 555 could be driven from 2 other 555 timer having their outputs common? i can do at the most that a gap of 2-5 seconds between each timer. But will it work?
