Re: a ircuit to swith a relay by alarm clock

It really depends on what type of alarm clock you use(AC/DC) and what you want to drive with the relay(AC/DC/Load/etc...)

If you just want to set up a relay to go off at a certain time of day, I would use a cheap wrist watch, connect the piezo beeper wires to an opto coupler which will drive a tranistor and in turn a relay, plus it's nice an small so it will fit between the sticks of dynamite!!!

(Thats just a joke BTW!, If you would like to explain what you are going to use this for I would be happy to email you a schematic+parts list, but not if it's for a bomb)
