Every now and then I want to test a circuit or a new sensor or even some new idea for code but I don't have a starter kit or anything.

I just received the PICAXE 8 Pin Proto Kit from Sparkfun (yay) and it comes with what looks like a 9v battery snap clip but the datasheet says that I cannot use a 9v battery.  The text states:
