Sure I can provide all the info you need. I will get it written up on my mini project blog site; retromini.co.uk with photos, parts list and source code for Arduino. In the meantime here is a summary; - Removed speedo internals leaving just the face - mounted a stepper motor on modified bracket behind face - mounted OLED behind face for odometer display - programmed Arduino to perform all the calculations, control the OLED and stepper motor How it works - Speed pulse signal counted by Arduino over 1 sec - Arduino calculates current speed by converting pulses over 1 sec to mph and then converts that to a stepper motor position moving the needle accordingly - Meanwhile Arduino is counting 1/10th of mile and updating various EEPROM locations to keep track of distance covered. This value is written back to EEPROM each time speed = 0mph

- Removed speedo internals leaving just the face

- mounted OLED behind face for odometer display
- programmed Arduino to perform all the calculations, control the OLED and stepper motor
How it works
- Speed pulse signal counted by Arduino over 1 sec
- Arduino calculates current speed by converting pulses over 1 sec to mph and then converts that to a stepper motor position moving the needle accordingly
- Meanwhile Arduino is counting 1/10th of mile and updating various EEPROM locations to keep track of distance covered. This value is written back to EEPROM each time speed = 0mph
Can u help me??Library switex25...is not work?
Wow that's cool. Can you give some detail on how you did it?
Odometer!
Can u help me?...library switex25 is not work?
Will this work on any gm aplication? Like in a ls swap. Since its a gm stepper motor.
