Heads-up RPM gauge using neopixel sticks

Project Share
1

Summary

  • Uses Mode 1 PID 0x0c for RPM, should work on most vehicles!
  • Polls and displays faster than my cluster’s RPM gauge!!
  • Brighter Indicators at 1k,2k,3k,4k,5k,6k,7k
  • Needle changes to Magenta when passing SHIFT_POINT_RPM

TODO

  • Add a physical brightness trimpot to the setup to control the brightness (Day/Night needs a big difference in output)
  • On/off switch for the OBD-II port so I don’t have to unplug it
  • Make all wires black
  • Mount display possibly using blue tack, and mount it a bit closer to the windshield so it’s also lower on the “heads-up” display.
  • Add a pleasant sounding piezo for the shift point?
