Tenor Wolfelele Ukulele
It took me about 45 minutes (not including glue drying time) to put together a service-able ukulele from Wolfelele’s precut wooden components. The well-designed parts fit together in a way that ensured it didn’t end up crooked, and the triangular instrument sounds better than any other $100 ukulele I’ve played. The kit has everything you […]
TriTrix MTM Speakers
Speaker design master Curt Campbell has created several dream kits for the audiophile, including the TriTrix. Featuring two 5.25″ Dayton Audio woofers and a single tweeter in MTM format, the final product has an easy, 8Ω load that can be used for audio or home theater systems. The transmission line kit includes precision-cut MDF for making the cabinets, […]
Nebulophone
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 […]
Pico Paso
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 […]
Thingamagoop 2
Analog voltage-controlled oscillators (AVOs) make a variety of intriguing hums, beeps, buzzes, and loops, controlled by buttons, knobs, and sensors. These are fantastic group projects because once the soldering irons are all put down, you get an excellent payoff: you can have an impromptu concert. Bleep Labs, run by Austin, Texas, circuit bender and kit […]

I’ve been living car-free for 12 years. When I first saw Xtracycle’s cargo bike conversion kit, I was impressed by the broad utility of the design; it can be used to haul cargo and also passengers. I decided to build the ultimate people-and-stuff hauler so I could pick up friends who don’t bike and we could […]
Brain Machine
Hack your brain! Put on these glasses and headphones, close your eyes, and enjoy some harmless hallucinations as you drift into deep meditation. You’ll come out after the 14-minute program feeling fabulous. Sound and Light Machines (SLMs) help people sleep, wake up, meditate, and more. They work by generating light pulses (seen through closed eyelids) […]

Cloning a Fluorescent Gene
When I told my 8-year-old daughter I had a kit to clone fluorescent jellyfish DNA, she was excited to try it. But this is a high-school level project. The reagents are sent in a styrofoam box with dry ice, and the projects require a polymerase chain reaction thermal cycler (which Genotyp will loan out to classrooms that […]
TubeSat Personal Satellite
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 […]
SpikerBox
This is a solder-together kit for studying the electrical impulses of cockroach neurons. The online instructions are excellent, with videos and plenty of clear photos of the assembly process. My 8-year-old daughter identified and inserted all the electrical components into the clearly marked printed circuit board through-holes, and I did the soldering. She asked me […]
