when you say 0.3 and 0.6 do you spacing between the holes/pads? Or the size of the pads themselves?
Thanks for the tip on the AVR, i had no idea you could program AVR's with basic, their seems to be a lot of supported chips too. I took Basic a million years ago, back when it used things like GOTO,and GOSUB, but it's all pretty easy. I have a couple of picaxes that uses real simple basic commands. Looks like i might buy myself a couple AVR's for xmas.
