Hi Russel, thanks for the response.
Since you're so knowledgeable in electronics, maybe I can ask you the following:
I am looking for a pinout diagram of any inkjet cartridge. (thermal, piezo or electrostatic).
OR
How do I make a cartridge to drop ink droplets? I know it is possible to make a thermal inkjet cartridge to run off a battery, since HP just released a small portable inkjet color printer that does just that.
I have a really awesome (art)project in my head, and I really want to get it out into the real world. but I need a lot of help.
