  • Lord Vetinari’s clock from Discworld inspired a real-life version with irregular ticking.
  • The clock uses a PIC12F683 microcontroller with a 32.768Khz crystal for accurate timing.
  • A 'random' sequence over 32 seconds makes the clock appear irregular but keeps accurate time.
  • The design includes current limiting resistors and Schottky diodes to protect the microcontroller.
  • The project is open-source and open-hardware, with files available for download.
  • A kit version is available from Akafugu.jp based on the ATtiny25.
