People my age remember red plastic toy rockets from childhood that you filled with water, pumped with air, and watched as they leaped dozens of feet into the air. Well, things have gotten far more serious in the world of water-powered model rocketry, and hobbyists are reaching heights upwards of 800′ using plastic soda bottles, thin […]

Aimed at kids 8 and up, this kit has real heart. Its 48-page workbook and components (solar cell, buzzer, two motors, LED, capacitor, copper rivets, pinwheel, etc.) take you through lessons and fun experiments that teach the basics: What is energy, as distinct from force? What forms does it take? How can it be converted […]

This kit includes everything needed to build a solar-charged, nighttime-activated, light-pulsing lamp. It charges all day from the SCC3733 solar cell, and “pumms” the four ultra-mega-super-bright LEDs to cast artistic silhouettes against the walls of the stylized cardboard lantern. The LEDs are a random grab of white, blue, red, orange, and green. Basic soldering is […]

The MintyTime Clock Kit is a fun way to add a binary clock to almost any container. It’s intended to be housed in a mint tin, such as the classic Altoids tin, but it looks great in almost any container, from a custom-designed, laser-cut enclosure to an old wooden recipe box.
