I've been working on my fish lately, and need a 1Hz or 2Hz timing circuit to test the tail with.All it has to do is swap the polarity of two wires.
That said, a 555 timer configured for 1 Hz (http://sites.google.com/site/uzzors2k/555Tester_schematic-full.jpg) is actually cheaper and simpler - why the aversion to ICs?
All it has to do is swap the polarity of two wires every second(or half second with 2Hz)
Get a cheap wristwatch and use the circuitry inside it.
Write a quick piece of code for the Atmega to toogle an output pin.

well given what you are saying all you need is a double pole double throw switch. it is really easy, and that is really all you sound like you need.2 bucks from dick smiths

What is a transistor AMV?I am a total noob...
I don't want to wait 2 weeks for ICs and transistors to ship, I need it now!
I first thought of a RC circuit(Resistor Capacitor circuit)but my experience is limited....
