Film Drum Roller

A repository containing the embedded code for a DIY film drum roller (to be added later)


  • Radu Corcodel
  • Danny Spence

To Do:

  • Capture case when sequence changes RPM but in the same direction
  • Derive new equation for mapping cosine to byte when the byte doesn't start from 0 or end at 255
  • Derive new equations for controlling ramping time based on difference in RPM
  • Make custom PWM brackets (0-255) doesn't necessarily correspond to (0-n)RPM because of internal friction, magnetic field saturation and moments of inertia
  • Store and read pre-built programs from EEPROM
  • We should probably have an E-stop button too (maybe hooking it up as an interrupt)
You can’t perform that action at this time.
