I passed by the electronics shop today and bought the components for the "Patxipt" version of your ignition.
I'm still confused about the schematic, the 1 Ohm resistor seems to be superfluous (only to measure current?)and the coil secondary ground should be connected to the primary ground.
Photos of my module follow as attachments. Will try to test this week on the bench.
The connector next to the 7805 voltage regulator has the same pinout as a servo lead, Ground-Vcc-Signal. I also replaced the 7555 for a NE555 IC, since the former wasn't available.
