Homebrew PCBs

The details of the method and the initial technical details of the 
first version of V's modification are all here:
http://techref.massmind.org/techref/pcb/etch/cx4200-vs.htm
and I will be overjoyed to post any additional technical details on 
that same site. 

While this list is fantastic for discussing those sorts of thing, it 
makes more sense to have a distilation of the details, leaving out 
all the chatter, on a web page.

Other simular modifications and general information about direct 
inject etching are here:
