    If you are having troubles with the Monitor12V.py script monitoring ignition voltage on pin 40, change GPIO.setmode(GPIO.BCM) to GPIO.setmode(GPIO.BOARD).This fixed it for me. With it set to BCM, I was locked out of the Pi due to it sending the shutdown command right when the PI booted up. I had to take the SD card out, and manually rename the file to something else just so I could boot up again. Then I debugged. I found that issue with the Monitor12V.py script. BOARD mode uses the pin numbers as they are numbered by the PI. BCM mode uses a numbering scheme that is tied to the Broadcom chip specs.I feel like this fix should be for all Pis, but I could be wrong. I am using a Raspberry Pi 3b.Hope this helps someone!

  • Hi I am wanting to make this. But I want it bigger around 22x16 inches. Your source files cncparts.ai gave me an error "Could not find linked file "stranger things wall.png" " I was hoping to edit it possibly for bigger printing. How did you make it originally? I also noticed it was pixelated in areas which would look even worse when blown up. Any suggestions?
