Electronic Circuit Building Blocks, Screen-Free Science Kids Love

A hands-on electronics kit for curious kids. Snap the modules onto the base plate, connect them with the plug-in wires and watch a fan spin, a flying saucer launch, lights glow and sounds play. Every project teaches how real circuits work, like switches, sensors and series and parallel circuits, while it feels like play.

Up to 168 projects. Each set comes with dozens of builds, from simple first circuits to master-level challenges.

Learn by building. Kids discover switches, sensors, resistors and motors by making them work.

Plug-in wires, no tools. Modules click onto the base plate and connect with simple plugs.

Screen-free fun. Hours of hands-on play for kids 6 and up, at home or in the classroom.

How It Works

Lay out the base plate and pick a project from the guide. Snap the modules into place, connect them with the plug-in wires and switch on the power module. Start with simple circuits, then move up through intermediate, advanced and master builds as your child learns.

Each set includes different modules, so the projects you can build depend on the set you choose.

Your kids want to play on screens, and you want them to learn something.

Every rainy afternoon ends the same way: they're bored, they ask for the tablet, and an hour later they're still scrolling. Most toys get a few minutes of attention and then end up at the bottom of the toy box.

You want something that keeps their hands busy and their brains working, and that they actually want to play with.

Colorful electronic circuit building blocks with fan, flying saucer, lights and spray module

Circuit kit projects shown at primary, intermediate, advanced and master levels

Real circuits they build with their own hands.

Kids start with a light and a switch, then move up to fans, flying saucers, music and sensors. Each build shows them how electricity flows, and every success makes them want to try the next, harder project.

The projects grow with them from primary to master level, so the kit keeps them busy for weeks, not minutes. It's a great pick for birthdays, holidays and rainy days at home.
