Homebrew PCBs

Well, Russel,

maybe we can all stop bickering and rather use the valuable answer time
for generating useful posts.

You say you have made such a machine, tell me more.
Especially tell me what you do about your software, and
how the pneuamtic plunger works. i think i have all components
for a pneumatic system here (pump, pressure regulator, several solenoid 
valves).
I think it has some potential advantages and would like to give it a try.
I do not remember exactly how the air was coupled to the syringe, would it 
work
to simply apply the air pressure to the already existing plunger-back and 
seal
off the syringe housing?

thanks
