Welcome to the
workshop.

I build embedded hardware projects and try to explain them well enough that you could build one too. If you grabbed one of my PCB cards — nice, that's a real dev board. Here's what you can do with it.

Getting Started with Your PCB Card

You've got an ATmega328PB dev board in your hands. Here's how to plug it in, install the toolchain, and blink your first LED. No Arduino IDE required (but it works with that too).

Show & Tell

Builds

LED Physics Cube

A falling-sand physics sim running on a six-sided LED cube. Tilt it and the particles tumble. ESP32-S3 brain, IMU for orientation, 384 LEDs, and a lot of C.

PCB Business Card

The card you're probably holding. A real ATmega328PB dev board in a business card form factor, designed in KiCad and fabbed at JLCPCB. Yes, you can program it.
