Homebrew PCBs

Hi Robert,

Another PIC type uP is the PICAXE, it is programmed in
basic, and only requires a 3 wire serial cable for
programming. The PICAXE website has a lot of info on
interfacing, including stepper motors. A 8 pin PICAXE
chip will set up back $3. Its bigger brother the 18
pin will set you back around $10.

Start up cost to try the PICAXR is about 5 bucks. The
software is all free and downloadable from the PICAXE
website. A old serial mouse cable can be made into the
programming cable.

I'm working on a PICAXE based pcb driller with stepper
motors, using th 8 pin $3 PICAXE chip.
