- Put a 2.1mm DC power plug on the wire from my PSU board to the JimStim
- Soldered a 16 way IDC cable to the JimStim to carry 2 x "tach" pulses, 6 x "ign LED", 2 x 5v, 5 x ADC pots, 1 x spare goes to ADC
- Added a socket for that on the H1 proto card and wired that to the appropriate MCU pins via buffer circuits (8 x PWM, 2 x ECT, existing ADC inputs)
- Soldered a header to the H2 board
- Added four rubber feet to each of the four external boards
Additional circuits :
JimStim ribbon complete (note "IAC" LEDs are wired, one in each polarity, to the two "tach" signals) :
Here it is all together with the most important, a glass of good red wine! :
Thats over a quarter of the pins brought out to circuits now :-)
