Help Please, I want to drive a 180 nm stepper manualley

I can put the code to a PIC for you but it isn`t the best - good enough for me but was never really intended to share.
Basically the circuit is so simple. There are a number of pins on the PIC. One of which is +5V (so you need to make some sort of voltage reg.), the other ground, then their are a number of buttons. Finally one pin is connected to the step of the driver and the other is sent to direction of the driver and that is it! The PIC does all the work. I`m not really into electronics so the only thing I found a little tricky was the arrangement of a few resistors (pull up or pull down, I forget) on the buttons.
My daughter has now stopped crying so I`m going back to bed!!!!! ::) I`ll let you know more tomorrow and take some pictures after work.

Peter, wouldnt it be better if you bought a kit to do this say from Quasar Electronics?
I bought one of these: http://www.quasarelectronics.com/3179-standalone-computer-controlled-unipolar-stepper-motor-driver.htm
to drive the same motor..

so can that be used without a computer ?

They look good, I bought one off ebay, sime idea with a step and dir button. I`m 99% sure everything was wired correctly as it run for about 2 minutes and then suddenly the driver board starting smoking and it all went down hill from there. I was only testing it and I couldn`t see anything wrong so why it did it I don`t know. I then purchased the Arc Euro driver and it ran just fine on the same setup and then I made my stepper board....but they look much easier than trying to make one!
