Free to read, no account neededOpen-source toolchain

Learn hardware engineering in pieces you can finish, and have every one of them checked by a human.

35 skills. Six to eight hours each. Every one ends in something you build on your own — a calculation sheet, a simulation, a capture file, a routed board, a bring-up log — which an evaluator then validates or sends back with specific feedback.

Modality — how you take a skill

Two routes through every skill

The same project and the same acceptance criteria either way. What changes is how much of the material you sit through first.

  • Route A

    Work it through

    You have not met this before.

    Read the concepts, follow the worked example, do the tool demonstration in KiCad or ngspice or FreeCAD, then build the project. Four to six hours of material, two to four hours of project.

    • Concepts written out, not a reading list
    • One problem solved end to end with real numbers
    • Keystroke-level tool instructions
  • Route B

    Audit it

    You already do this at work.

    Skip straight to the project. Build it, then hold it against the competence checklist — the same rubric an evaluator uses. It counts identically. The system records competence, not attendance.

    • Learning material hidden by default
    • Same project, same acceptance criteria
    • Your portfolio shows it was audited, honestly
Modality — how it is judged

Self-assessed, or validated by someone else

You can do the whole thing without an account. What an account buys is the part you cannot do for yourself.

  • No account

    Self-assessed

    Everything is readable and workable signed out. Progress lives in your browser. You tick your own competence checklist, and the app is clear that nobody else has looked at it.

  • With an account

    Validated by an evaluator

    Submit a finished skill. An evaluator opens your artifact and your notes and records validated, or not yet validated with specific feedback about what is missing. Then you fix it and submit again.

Not yet assessed

Submitted, sitting in the evaluation queue. Nobody has looked at it yet.

Not yet validated

An evaluator has looked and written down what is missing. It comes back to you with the feedback attached, and resubmitting puts it back in the queue.

Validated

Someone other than you has checked the work against the acceptance criteria and signed it off. This is the only thing that counts towards a track.

There is no certificate at the end and nothing is awarded by an authority. What you hold is a portfolio of built artifacts, each one with a named evaluator's sign-off against published acceptance criteria. That is a harder thing to earn and a more useful thing to show.

What you study

3 tracks, sharing most of their skills

A track is an ordered set of skills grouped into stages. Start with the first if you are new; the other two reuse most of it.

  • 32 skills216 hours

    Digital PCB Designer

    From what a volt is to a fabricated, brought-up, reviewed board.

    The core track. It starts at charge and current and ends with you releasing a manufactured four-layer digital board with a documented bring-up, an errata list and a design review behind it. Every skill produces an artifact; by the end you have a portfolio of around thirty pieces of evidence rather than a certificate.

    30 of these skills are shared with the other tracks — finishing one puts you most of the way through the next.

    Embedded Hardware Prototyper

    Design the board, write the bring-up firmware, and make it fit the box.

    Shares most of its skills with the Digital PCB Designer track, then diverges into firmware bring-up and mechanical integration. Built for people who need to take a whole small product from idea to a working prototype in an enclosure, rather than to specialise in layout alone.

    Analogue and Power Designer

    Small signals, hot parts, and the layouts that decide both.

    Shares the foundations, bench and PCB skills with the other tracks, then goes deep on signal conditioning, switching power and the power integrity and EMC work that analogue boards live or die by. Take it after, or instead of, the digital-heavy stages.

Structure

The same six parts, every skill

So you always know where you are, and so auditing means skipping something specific rather than guessing.

  • 01

    Concepts

    The ideas stated plainly, each with the equation worth committing to memory.

  • 02

    Worked example

    One real problem, solved step by step — usually including the step where the obvious answer turns out to be wrong.

  • 03

    Tool demonstration

    Do it for real in KiCad, ngspice, FreeCAD, PulseView or Digital. Netlists and menu paths included.

  • 04

    Resources

    Specific free readings and videos, each with a note on which part to use and how long it takes.

  • 05

    Project

    Two to four hours, built alone, with deliverables and acceptance criteria.

  • 06

    Competence checklist

    What you must be able to do. Also the rubric your evaluator uses.

Cost

Open source, all the way down

Every tool in the curriculum is open source, and every reading is free. Where no open tool exists with the data you need — real measured capacitor bias curves, live distributor stock — a free proprietary one is used and labelled as such on the page.
