Personal electronics lab — bus analysis, embedded systems, hardware teardowns
A collection of hands-on hardware experiments, firmware work, and protocol analysis. Each project folder contains its own README with setup notes, wiring diagrams, logic analyzer captures, and lessons learned.
| Project | Preview | Board | Topics |
|---|---|---|---|
| hb0100-centurion |  |
Raspberry Pi Pico (RP2040) | SPI display, I2C IMU, logic analysis, TUI serial |
| null-key |  |
Waveshare Pro Micro C (ATmega32U4) | USB HID, KiCad PCB design, AVR, open hardware |
- Logic Analyzer: NanoDLA (PulseView)
- MCU: Raspberry Pi Pico / RP2040, Waveshare Pro Micro C (ATmega32U4)
- IDE: Arduino IDE with Earle Philhower RP2040 core
- Terminal: screen / PuTTY
These aren't polished tutorials — they're lab notes. Mistakes, dead ends, and wrong sample rates included. The goal is to understand what's happening at the silicon level, not just make the demo run.
