The kit that grows up with your kid.
Not another build-it-bin-it STEM box. TinyOhms is a ladder of ten levels — each adds a few real components to the box your kid already owns, and every project can use everything collected so far.
How it works
1 · Start with Level 1
A real toolbox: breadboard, LEDs, resistors, switches — and the case they'll fill for years.
2 · Build & tinker
Real circuits with the real math, ending in open challenges — not follow-the-steps manuals.
3 · Level up, keep everything
Each level adds a few parts that multiply what the old ones can do. Nothing gets binned.
Why parents pick TinyOhms
the box
Nothing gets binned
Real breadboards, LEDs, sensors — parts engineers actually use. The Wi-Fi plant monitor at Level 10 still runs on LEDs from Level 1.
the site
It knows your box
Tick off what you own and TinyOhms shows every project you can build tonight — and what you're two parts away from.
the learning
Understand, don't follow
Every project shows the real math and ends with an open challenge — not a 14-step manual to follow and forget.
The ladder
Ten levels, marked the way engineers mark resistors — with color bands. Each unlocks new parts and multiplies what the old ones can do.
- 1 Light Your first circuits — make light happen.
- 2 Sound Add noise. Doorbells, alarms, annoying siblings.
- 3 Sense Circuits that react to the world around them.
- 4 Motion Make things spin, wobble, and go.
- 5 Control Precise movement you command.
- 6 Logic Chips that count, time, and decide.
- 7 Code Program everything you already own.
- 8 Environment Measure weather, soil, and the room.
- 9 Robotics Wheels + everything so far = robot.
- 10 Connected Your projects, on the internet.
