As a Solution Architect, I work with high-level abstractions. To refresh my low-level skills, I decided to get back into hardware.

I hadn’t done any soldering in over 20 years, so I used this DSO138 oscilloscope kit as a warm-up project to calibrate my skills.

The main objective next: assembling a retro Z80-based computer running CP/M.

Whether designing cloud infrastructure or tracing PCB circuits, the core logic of system architecture and debugging remains the same.
