Homebrew PCBs

Hi,
Toner Transfer is an acceptable method for fast pcb prototyping.
It has 2 disadvantages : the drilling should be made manually and the
image doesn't have exactly the same dimensions as designed - this way
the automated drilling it's not possible directly.

For Mach3 driven, cnc owners I have made a solution based on a webcam
mounted aside from drilling motor, a modified video plugin and a small
program for conversion/rotation/scale of excellon drilling files.

If it's someone interested in this solution - I will post all the
needed info. 

Regards,
Daniel
