The Oregon Kombucha kit comes with everything you need to make your own kombucha at home. The instructions are clear and easy to follow.

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 […]

Due to its hands-free interface (your body’s interference with its electromagnetic field controls the sound), the theremin is famed for both its novelty and its importance in 20th-century music. When I started building this kit, I had little soldering experience, but the straightforward instructions made for a great introduction to the world of circuits. The wooden casing […]

If you get 3–5 harvests, the kit is a bargain; […]

This wild-looking R/C plane is life-sized (78” tall) and can take off vertically! The kit makes a superhero-shaped fuselage; you add R/C gear. Directions are clear, and the laser-cut parts go together smoothly, but it’s a bit tricky — a fun and unique kit for experienced builders that will definitely command attention! 57” hero plans […]

Eight mini servo motors and an assortment of acrylic pieces combine to create the QuadBot, a low-cost, four-legged robotic pet you can assemble in under an hour. The kit doesn’t come with brains or batteries; add those yourself. Each leg uses two servos, making this a 2DOF (two degrees of freedom) walkerbot. Exercising a bit […]
