What’s kombucha? It’s a refreshing, lightly sweetened, sparkling tea drink that is naturally fermented (yet non-alcoholic). The Oregon Kombucha kit comes with everything you need to make your own kombucha at home. The instructions are clear and easy to follow. Boil a gallon of water, brew the tea satchel, dissolve the sugar, let it cool, […]

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 […]

Spike Your Juice is a simple introduction to home fermentation. The kit comes with enough yeast packets for six batches, an airlock with rubber stopper, and clear instructions. To brew a batch of alcoholic juice, add one yeast pack to a 64oz bottle of juice (such as grape or cranberry), shake, stopper with the water-filled […]

If you like high-voltage sparks arcing through the air (and who doesn’t?), check out the Coil Driver, which drives an automotive ignition coil at audio frequencies. Like other musical kits, the Coil Driver makes a great group build because you can all make cool sounds together when you’re done. However, while it’s an easy solder, […]

Another small synth from Bleep Labs, the Nebulophone is more robust than the Pico Paso. It packs three potentiometer knobs, two buttons, an LED/light sensor combo that serves as an analog low-pass filter, and a unique piano-like series of pads on the PCB that you can control with an alligator clip. It has a programmable […]

This tiny, handheld synth features two light sensors, two pots, and two buttons. It’s an easy build, even for newbies, soldering together very quickly with no difficult steps. I love how snug the little guy is, but this compactness comes at a price: no enclosure and no speaker. To hear the Pico Paso, you’ll need […]

TubeSat makes space your personal laboratory. You build a satellite the size of a large soup can, get it launched into a 310km Earth orbit moving 17,000 miles an hour, and talk to it via ham radio a few times a day for 1–3 months. Smile as you reflect on your new skills in surface-mount […]

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.

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 […]

Although the V90 is an entry-level machine, it’s decidedly not a toy. The way it functions is complicated — a platform carries the tool holder; a larger gantry moves the tool back and forth; the frame positions the gantry; and it’s all driven by a motor turning the screw interposed between two shafts. Indeed, this […]
