The littleBits kit is like Lego for basic circuits. Each “bit” is a small circuit board that enables a single electronics component or electronic function, like a potentiometer, light sensor, LED, or motor. The bits snap together magnetically with edge connectors that are color-coded to indicate their general role within a circuit; for example magenta […]

This is a fantastic introductory electronics kit that comes with your choice of large red or green LEDs and everything else needed (aside from a soldering iron, solder, and flush cutters) to make one electronic 6-sided die. (The manufacturer says: “The name Dice Kit sounds a great deal better than ‘Die Kit’, so we bent […]

I’ve been building OWI robot kits since the mid-1980s. Some have been good, a few not worth the box they came in. Every once in a while, OWI does a kit that’s great — their 3-in-1 All Terrain Robot (ATR) is one of these. This entertaining kit, suitable for kids 12 and up, lets you […]

This pixel-scale, portable Meggy Jr game platform is fun for any gamer, especially those who know their way around an Arduino. About the size of a VHS tape, it offers an 8×8 matrix of RGB LEDs and a lot of functionality with very little setup. It comes pre-programmed with Attack of the Cherry Tomatoes, a side-scrolling […]

Chocoholics, take note! This kit allows you to make your flavor fantasies come true. It’s got everything you need to make basic, agave-sweetened chocolate, but I used honey instead and added lemon zest to create something out of this world. Ruffled paper cups are included, so the presentation is worthy of your sweetheart. After a […]

Named after the Norse goddess of youth, the Seas Idunn kit sets a high standard for DIY speakers. Cabinets come fully assembled in black ash, cherry, or maple, and the crossover also comes prebuilt, so installing it is just a matter of affixing it to the boxes and attaching the drivers. All told, the build took […]

Iced coffee is refreshing and delicious, but I’ve never been able to make it as well as I’d like. As it turns out, I was doing it wrong. Rather than prepare it with a traditional hot brew method, I should have been cold brewing it. This reduces acidity and produces a concentrated flavor that stands […]

You don’t have to depend on commercial growers or expensive powders to get your spirulina fix. With this kit, you can have it fresh and alive, anytime. I made a few modifications to help mine grow faster and prevent clogging, like replacing the intake line with rubber tubing and swapping the bubble wand for a […]

Who’d believe a sawdust log in a plastic bag could turn into a magical mushroom forest before your eyes! My first harvest was bounteous and the shiitakes delectable, but careful attention to growing conditions was required to yield multiple crops of mushrooms rather than mold. If you get 3–5 harvests, the kit is a bargain; […]

Making holograms became faster and easier a few years ago when Litiholo introduced its Instant Hologram film. Like old Polaroids, these film plates require no developing after exposure, which means, in about an hour, you can make your own transmission hologram of anything that will sit still next to the plate. The kit also includes […]
