Nice PCB - did you use a CNC router to do it? - if so, was it homebrew
- did a good job...

Thanks, the circuit was drawn out with a freeware PCB program. The image was
printed out with a laser printer on some enameled paper, the image was then
transfered
from the paper to the copper clad using a regular clothes iron and the paper
disoleved in water.
The copper clad was then etched in a DIY etchant consisting of muratic acid
and
hydrogen peroxide. There are several articles on the web that describe this
methode
of making DIY PCBs on the web in greater detail.

Best Regards
Tom.
