Find the perfect build for your kid. Filter by age, category, or difficulty.
Turn flat drawings into standing 3D sculptures with a heated pen that extrudes colorful plastic filament. A perfect intro to 3D thinking.
Cast crystal-clear or glitter-filled keychain charms using UV resin and a curing lamp. A magical intro to chemistry and design.
Build a real wooden birdhouse with real tools. Measuring, sawing, nailing, and painting — the complete woodworking intro.
Design and build a custom marble run from wood strips and dowels. Engineering, gravity, and endless tinkering.
Build a car powered by rubber-band stored energy. Wind it up, let it go, and race across the floor.
Build a ripcord-powered spinning disc launcher. Pull the cord, watch it fly — angular momentum in action.
Build a vibrating bug that scoots across the table powered by sunlight. A simple circuit that actually moves.
Design and build a custom insert that keeps all your game pieces, cards, and tokens perfectly organized. No more bags of chaos.
Build a tower that tumbles dice down internal ramps for guaranteed fair rolls. Works with any board game or RPG.
Build a mechanical toy that converts a hand crank into animated motion using cams and followers. The ultimate 'wow' build.
Build a wooden birdhouse with a WiFi bird-cam and dusk-activated LED lighting. Two independent circuits — one streams live video, the other lights up at dark.
The classic fairground steady-hand game built on a single board. Thread a wire loop along a bent course without touching — the buzzer catches every wobble. The perfect first circuit.
A single board, a grid of pegs, and a ball that bounces somewhere new every time. The friendliest introduction to probability — and later, to sensors and auto-scoring.
A chunky wooden block with seven LEDs in the classic pip pattern. Press the button and a random number glows — the build where 'random' stops being magic and starts being logic.
One pine board becomes a standing weather house. It reads temperature and humidity on a screen — then grows a soldering iron and two more sensors when your builder is ready.
An ESP32 reads soil moisture, light, and temperature for your houseplants — then shows it all on a live dashboard. Three build levels grow with your kid: decorate-only, full sensor wiring, or add auto-watering.
