Anyone ever experimented with injecting empty inkjet cartridges with conductive ink? Something tells me it's not that easy :). Curious if anyone has done this or been successful at printing with conductive ink?
You might need to mix the inks together due to the way an ink jet works (boils out little squirts of ink IIRC)
or you could Google it
sounds like something fun to try....
I know this is old, but... the black ink in many Canon and HP desktop printers is carbon based. I've never tested it for conductivity. Physical burnishing, IR Laser, or heating may alter its properties.
The "AgIC Print" project seems to have the problem solved. They sell the cartridge, cartridge+printer, or a refill kit (YMMV).
