Lessons
Browse every practical route from a current understanding to the next useful proof.
51 reviewed lesson routes with examples, traps, notes, cards, and practice steps.
Resources
Find the notes, cards, lessons, and practice paths.
Use this page when you already know the type of learning asset you need. Start with projects when you know the build, topics when you know the domain, and practice when you need a check instead of more reading.
Resource routes
Each route below has a different job. Use the one that matches what you are trying to do next.
Maker skill areas
Choose by domain when you know the kind of thing you want to build or understand.
Math, games, RF, electronics, hydraulics, fabrication, robotics, software, Linux, and data routes.
Project paths
Start from a build outcome and follow the sequence of lessons that supports it.
Good when the artifact matters more than the abstract concept list.
Obsidian-ready notes
Download Markdown notes with backlinks, source URLs, traps, and next actions.
Use these in a local vault beside project files, sketches, measurements, and source links.
Flashcards
Download Anki-compatible TSV decks for review that focuses on reasoning, not flag memorization.
Cards point back to the lesson so the source context stays attached.
Tutorial notes
Turn useful YouTube tutorials into timestamps, warnings, cards, and a small proof task.
The page stays useful even if a video changes because the written lesson carries the reusable idea.
Practice tasks
Use compact checks when reading is not enough and you need to prove you can apply the idea.
Practice pages link back to the lesson, reference, note, and deck that support the task.
Command-line checklist
Use recurring command patterns when a project touches files, logs, DNS, Nginx, services, ports, or deployment state.
Best for makers who need enough Linux inspection to ship and repair small project sites.
Full site map
Open the complete human-readable route map when you need to audit or jump across the whole library.
Useful for finding pages that are not in the main navigation.
Buy me a cup of coffee
TopicLadder is free to read. Coffee support helps turn rough maker ladders into clearer project paths, notes, cards, and practice labs.
