Real hardware.
Real code.
No pretending.

A maker curriculum for kids 9–15 who think in systems, not stories. Wire it, code it in real MicroPython, watch it work. Predictable steps, no timers, no streaks to break.

Why circuitworks

Designed for kids who need the instructions to actually match reality.

Not "inclusive" as an add-on. Built from the ground up by someone who needed this exact thing to exist.

01 — PREDICTABLE

One fallback, every time

Stuck on a step? There's exactly one troubleshoot path, worded the same way every time. No guessing which of five hints applies to you.

02 — LITERAL

Say what you mean

Instructions describe exactly what to do and what should happen. No "just play around and see" — every step has a defined, checkable outcome.

03 — SELF-PACED

No clock, no streak

No timers. No daily streak to lose. Pause a mission for three weeks and pick it back up exactly where you left off, pressure-free.

How a mission works

Fixed sequence. Real output. A certificate that means something.

01
Wire it
Follow the labeled diagram for your kit tier — breadboard for Tier 1, protoboard once you've leveled up to soldering.
02
Code it, in the browser
A real terminal talks straight to your board over Web Serial. Real MicroPython, no simulator standing in for the thing.
03
Stuck? One fixed fallback
Same troubleshoot path every time you hit this step — not a different hint depending on mood or phrasing.
04
Finish, get proof
Completion unlocks a printable certificate — optional, opt-in, yours to skip entirely.

Kit tiers

Start with jumpers. Level up to a soldering iron when you're ready.

TIER 1
No-Solder Starter

Everything clips together. Zero soldering iron in sight for mission one.

  • Small breadboard + jumper wires
  • Micro servo + LEDs + buttons
  • Small ESP32 board
  • Resistors and capacitors
Get Tier 1
TIER 2
Level-Up Solder Kit

Gated behind Tier 1 completion. Safety card is literal step one — no surprise irons.

  • Small protoboard
  • Soldering iron + safety card
  • Everything from Tier 1, permanent
  • Next mission set unlocked
Get Tier 2

Chromium browser. A board. Twenty minutes.

Web Serial runs in Chrome and Edge — plug in and go, nothing to install.
