HackerBox #0028: JamBox

I like it when the new HackerBox shows up on a weekend.

I always see electronics projects for making some kind of digital synthesizer to generate sounds so it seems to be a common project. It’s one I’ve never done, so I’m looking forward to experimenting with this box.

The official content list from the Instructable:

  • HackerBoxes #0028 Collectable Reference Card
  • Exclusive JamBox Printed Circuit Board
  • ESP32 DevKitC
  • CJMCU PCM5102 I2S Digital-to-Analog Module
  • Four MAX7219 8×8 LED Matrix Modules
  • Five 10K Ohm RV09 Potentiometers
  • Five Potentiometer Knobs
  • Eight Tactile Momentary Buttons
  • Four Adhesive Rubber Feet
  • 3.5mm Audio Patch Cable
  • MicroUSB Cable
  • Earbuds with Case
  • Exclusive HackerBoxes Skull Decal
  • Octocat Fan Art Decal Sheet

Unfortunately the demo code included in the guide only uses the potentiometers, buttons, and LEDs. Will need to do some tinkering to turn this into a synth.
