Slices of a clock

There are so many ways to tell the time. DIYers have been doing clocks since the Ancient Egypt (obelisks lacked portability, thou). Every modern maker has a clock amongst her first projects. I have done some myself, including a fibonacci clock, a wordclock with a fancy green matrix effect and an unreleased project that hopefully will see the light someday soon.

But recently I came back to the idea behind the wordclock before, to extend it in different ways:

  • Replace the ATMega328P with an ESP8266 (NTP support and user interaction)
  • Smaller sizes (8×8 LED matrices)
  • Smaller PCB, less buttons
  • Add buzzer for alarms
  • Replace the 3D printed part with a wooden grid cut in laser
  • Completely closed enclosure, better presentation
  • Fix some issues with the original board (like the lack of a beefy capacitor across the LED matrix power lines).
