Don’t just read about it.
Build it.

Hands-on Courses for 13–18 year olds. Wire real circuits, break them, fix them, keep what you make.

I’m a Learner

Sign ups open soon. Parents set up accounts for their Learners.

A transistor NOT gate built on the breadboard, its LED lit. — Breadboard

A half adder wired from an XOR and an AND gate. — Logic gates

A breadboard Lesson’s stages, from Place parts to Repair. — Six stages, ending in Repair

build. break. fix.

You learn how a computer works by wiring one up, a gate at a time.

The logic Builder running a half adder: A is 1 and B is 0, so sum is 1 and carry is 0.

Build real circuits

Wire gates together in the Builder and watch the signal move. Flip an input and see exactly what changes, and why.

Try it in the chip Course

A breadboard Lesson’s six stages, from Place parts to Repair, which unlocks once the build passes.

Break it, then fix it

Once your own build works, you get a working design with one mistake hidden in it. Track it down and make the lamp light again.

Earn the parts you use

Build an adder yourself and it becomes a Chip you can drop into bigger circuits. By the end, your computer is made from parts you earned, every one of which you built once.

Parents see progress, not homework

You set up the account and see how each Learner is moving through their Course and what they’ve unlocked. Their work stays theirs, and Learners are never ranked against each other.

The same Builders Learners use. Change anything; nothing is saved.
