Projects, places & field notes

MY Tinkering Journey Powered pushed further by AI

A personal journal about engineering projects, travel, photography, diving, and the practical lessons I want to remember.

One journal, two threads

From the workbench and beyond it.

Inside the workshop

Where software meets the physical world.

These are the areas I keep returning to—usually with a screwdriver, a serial cable, or too many browser tabs nearby.

01

AI and automation

Self-hosted agents, local models, and practical tools that make multi-step work easier to see and control.

02

Homelab and networking

Home servers, Docker services, NAS storage, Pi-hole, tunnels, monitoring, and the network that holds it together.

03

Embedded systems

Small computers, LicheeRV Nano experiments, embedded Linux, sensors, FPGA logic, and hardware-software boundaries.

04

Software engineering

C++, object-oriented design, university assignments, web tools, and software built to solve a specific problem.

05

Hardware and PC systems

PC builds, upgrades, repurposed components, troubleshooting, thermals, performance, and learning by taking things apart.

A note from Alfred

“I use this site to remember what I built, where I went, what surprised me, and what I would do differently next time.”
