timer circuit

[Jeff Broner]

I don't know anything about electronics, but I'm willing to learn if this
project is possible: I'd like to build a very compact timer that runs on AC
115v 60hz. It would consist of a simple clock circuit that outputs to some
kind of programmable logic circuit. This circuit would be programmed to turn
a relay on/off at specific times of the day (it could be a one time
programmable type of thing). My ideal design would be all solid state and
fairly compact, like less that 1.5" (~ 40 mm) cube. What I'd basically be
making is a lamp timer like the ones you can find at walmart, but much
smaller and minus the digital interface. Is this possible, and if so how
cheap could it be made? Any suggestions on manufacturers of the components?
Thanks.

It will cost more than the ones Wal-Mart sell. If Wally World sells it, it
can't be done cheaper. And theirs arequite small enough.

It's doable, but how do you intend to set it?

Thanks,
