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 […]

Whether your motivation is the environment, the economy, independence, or you simply despise the oil companies, converting your diesel vehicle to run on waste vegetable oil (WVO) can truly be a rewarding experience. (You can get WVO free from restaurants, preferably higher end. Luckily for me, my brother-in-law is a head chef, and he has access to WVO.) […]

In an alternate Old West universe, folks played synthesizers, and they called ‘em “Phantastrons.” Incorporating tubes, steel panels, and a branded wooden crate ripe for customization, this is one unusual synth kit. The power supply comes mostly assembled, but the 30s-era “turret board” is a challenge for seasoned solderers. Not your standard volt-per-octave functionality; this oscillator […]

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 […]

Just one listen to this home-built, high-end tube amp, and you’ll quickly discover that there’s more to that classic song you’ve been listening to for years. It has nothing to do with nostalgia — tubes just sound more musical than pure solid state, and the PoddWatt is a prime example. So, what can you get from a […]

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 […]

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 […]

Conductive yarns that sense your touch are combined with recycled carpet fibers to form the soft switch. This kit appeals to kids, grandmas, science geeks — anyone who enjoys crafts […]

Solder: Time was a perfect father-daughter project: my 8-year-old assembled the components and I soldered. Afterwards, she had a chunky blue wristwatch that her cousin admired longingly, so we made another one for her. Now their friends are asking for them. I think we’ve started a trend!
