Why build hardware when you can buy off the shelf easily?  Arduino and 
other MCUs are available with any manner of I/O which will drive a 
relay.  Programming is all but idiot simple.  I recommend using Forth. 
You can learn to program in it in an hour and be very effective.

Never be constrained by the limitations of analog again.

I wouldn't go to the trouble of installing Forth on an Arduino just to toggle a relay, but I admire your loyalty to the Forth cause ;-)

If all he wants is indeed what is being asked I would agree with Mark. 
the OP should find a suitable circuit to work from in the 555 datasheets - if not
theres no shortage of them online. I doubt he'd neet to do anything more
than copy directly if he does a decent yahoo search.
It's possibly one of the most popular chips ever created.

On the other hand I'm quite a fan of microchip PIC's myself, if he wants to go 
digital that is.

I would, who would want that massive black box between a simple
micro and themselves?

Also, there is little problem to install a Forth on a common
Arduino target. 

I admire your loyalty to the dark side ;-)
