Description

For my best friend's 50th birthday a couple years ago, I decided to make him a Clock/Radio/Sound effects that looks something like the time circuit display in Back to the Future, since he's a huge fan of those movies. Here is a snapshot of where it is today. I've been adding new functionality to it and fixing things on it every year since.

Components

  • 1 × STM32F411RE Nucleo
  • 1 × MCP23017 I2C Input mux for the keypad
  • 1 × Adafruit SoundFX board
  • 1 × Cheap power supply board for 5v/4A supply off Aliexpress
  • 3 × Sparkfun level shifter boards For the MAX7219s. The ICM7228s didn't need them.

  • PCB to replace the spaghetti wire LED boards

    Mike Moretti • 12/30/2019 at 16:20 • 1 comment

    Last week I ripped out the spaghetti wire v1 LED board and replaced it with a PCB.  Soooo much easier to debug and much cleaner.

Make sure you have 1.21 gigawatts to power the flux capacitor!  ;)
