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.
