Computers
Hardware, software, operating systems, programming, and the long trail of tools and ideas that define personal and technical computing.
Overview
This is the intersection of technology, science, making, and the kinds of hobbies that turn into deep rabbit holes once you start collecting notes.
Some of these topics are highly technical, some are hands-on, and some are just hard to categorize anywhere else, which is exactly why they fit here.
Electronics
Circuits, components, troubleshooting, and the practical side of understanding how electronic systems behave and fail.
Math
Concepts, problem-solving methods, and the useful formalism that sits underneath engineering, computing, and scientific thinking.
Amateur Radio
Frequencies, propagation, antennas, equipment, and the global hobby built around radio communication and experimentation.
Models
Scale models and related hobby work where patience, reference material, and detail matter more than speed.
Model Railroading
Layouts, scenery, operations, rolling stock, and the satisfying combination of craft, mechanics, and miniature world-building.
Lego
A modular building system that can swing from simple nostalgia to serious engineering and custom design projects.
