My original spec of using special ink in a
bubblejet followed by etching and SMD hot air
soldering is not flaky at all.

The only real issue is finding a suitable ink,
and then the system would be many times cheaper
and faster than any commercial board house and
suitable for one-off with tiny PCBs.

I have discussed the ink issue with my girlfriend
(who is an industrial chemist) and the problems
should be simple so solve if anyone gave a damn.

I also checked the ink cartridge in my bubblejet,
it says "solvent = isopropyl alcohol" so obviously
the plastic and all mechanisms are alcohol safe.

This should make it EASY to find a suitable ink
or lacquer.

The problem of filling the bubblejet cartridge is
already solved with refil kits available at office
supply stores.

Cristian has solved the PCB feed issues or come
some of the way to solving them.

I have a piece of PCB cleaned and ready and am
trying different ink and lacquer ideas as the
ideas arise but I am busy with some important
projects right now.

Maybe if the brain bank spent less criticising
and saying "go to PCB house" (which is NO help
to anyone) some clever person here could find a
really smart ink solution. Or is it just Cristian
and myself who think that a "5 mins to soldering"
prototyping system is worth building?
