Homebrew PCBs

Currently, I am working on homemade CIS with my own auto-reset
circuit. I have completed first version of auto-reset circuit, it
emulates all ink cartridges with single micro. It is based on
MSP430F2130 from TI. It is emulating T60x (601,602,603 and 604) series
cartridges. This version uses internal RAM not flash to hold the ink
counters. I have faced timing problems with internal flash so for the
next version I will add external E2ROM. After completing new version
of auto-reset circuit, I will distribute object code and circuit
diagram to let everybody to do their own CIS system.
Note: I did it for CX4200 series most probably it will work for CX3810
and CX4800

Cheers,
