Real sensors & logic
Builds detect metal, respond to touch and switch on command — real electronics, not simulations.
Collection 02 · Discover Series
Builds that sense & respond
The Discover Series steps beyond first circuits into gears, sensors and real mechanisms. These are smarter, more involving builds for builders who've outgrown Explore — projects that sense the world and respond to it.

About the collection
A real level up in engineering
Explore teaches children that circuits work. Discover teaches them why — and how to make machines that react. Each kit introduces sensors, switches and mechanisms that respond to touch, light and movement.
These are weekend projects designed to be spread over a session or two, with enough depth to keep confident young builders fully engaged. Every kit still follows Zemble's rule: it works when it's finished.
- Sensors, gears and switching circuits that really work
- Ideal for ages 9+ and for kids who've finished Explore
- Complete kits with parts, batteries and picture guides
What to expect
Machines that think for themselves
Sensors, mechanisms and real problem-solving — the payoff for moving up a level.
Mechanisms that move
Gears, motors and linkages combined — builds that visibly do something useful and clever.
Deeper challenges
Longer, more satisfying builds that reward patience — perfect for weekends and club sessions.

The Discover catalogue
Five smart builds that bring sensors and mechanisms to life — every kit is still quality-checked before it ships.

"We moved from Explore to Discover after one term — the sensor builds genuinely feel like a level up."

Why choose Discover
For builders ready to level up
Natural progression
Discover is the bridge between first circuits and serious engineering. Kids who loved Explore will find familiar parts — and brand-new ways of making them respond.
The Zemble guarantee
Every kit is tested before it ships, and if a part is missing or broken we replace it free within 7 days. Support that answers when a build goes sideways.
