Hackerboxes #0028: Jam Box

The soldering for this one was a piece of cake. Everything was nicely padded and spaced.  Big pads make soldering way easier than a tiny ring.

EXCEPT for the potentiometers.  The strain-relief legs didn’t fit into the PCB holes, and Hackerboxes just suggested shaping them into a tube to make them fit, without any real guidelines on how to do that.  Anyway…

I hadn’t yet installed the Arduino IDE on my primary Macbook. No issues there. Had to install the ESP32 board into the Board Manager.  Then I had to install the VCP USB UART driver so that the serial port would show up in the Arduino IDE.

Then, BAM.  My sketch uploaded and works.

Yes, I know I didn’t install the pots yet.  I also didn’t install the DAC yet.  Maybe tomorrow.  I just wanted to light up the MAX7219 8x8s.
