Step 3Build a download circuit
This download circuit uses a picaxe chip, a couple of resistors, a regulator and a 9V battery. More information is available in the picaxe documentation and this should only take a few minutes to build once all the parts are to hand.
I might also add that picaxes do run happily on 3 AA batteries. A 5V regulated supply is useful for running analog inputs as the reference voltages don't change, but for simple on/off circuits a regulated supply is not needed. The 5V reg can be left out in these situations.

Why is no rs232 level converter necessary here?

Almost all computers now support TTL. The adapter sold by rev-ed does as far as I'm aware.
