Kit Complexity: 3
(1=Easy, 5=Difficult) Is the kit easy, moderate, or challenging to build for its most likely target audience? Kits clearly aimed at children would, for example, be rated differently from microcontroller kits.
TV-B-Gone Kit
Tired of all those TVs everywhere? Want a break from advertisements while you’re trying to eat? Want to zap screens from across the street? The TV-B-Gone kit is what you need. The new v1.2 works worldwide, turning off virtually any TV by running 230 TV power codes for Asian/North American and European IR remote standards. […]
Premium Berliner Gramophone Kit
Constructed from a motor and various bits of wood, plastic, and styrofoam, this retro gramophone kit offers the allure of carving grooves into compact discs and Dixie cups with a sewing-needle-based pickup and playback assembly. Illustrated instructions in both Japanese and well-translated English are included, and the hour-long assembly only requires a screwdriver, some scotch tape, and a […]
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, […]
MSA-R MIDI Decoder
This kit gets top marks for ease of assembly and low price, and because it’s preprogrammed to do all the heavy lifting, all you need to do is solder it together and attach it to the device of your choice. It’ll take an average-skilled solderer 1½ hours to assemble, and from there the possibilities are […]
Audio Gear: audio, MIDI, music
Water Bath Canning Kit
There’s nothing like prying open a jar of gleaming, homemade strawberry jam in January. This kit is a classic and contains everything you need to get started. It’s worth it for the magnetic lid lifter alone! (How many times have I burned myself fishing around the pot for lost lids?) For smaller batches, I like steam […]
Hi-Tech H45
If you want a more challenging high-power build experience, I like the Hi-Tech H45 kit. It’s big (2.63″ diameter and 49″ tall), with sturdy plywood fins and a durable plastic nose cone, and it can handle motor types F through I. I got my first high-power certification on this model back in 1990. Good times!
South-Pointing Chariot Kit
Indie makers RLT Industries of New Braunfels, Texas, sells this lovely wooden model kit of the classic “south-pointing chariot” mechanism. Set the chariot down with the vane pointing in an arbitrary direction — south, north, whatever — and a geared differential connected to the wheels will keep it pointing the same direction regardless of which […]
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) […]
Science: meditation, relaxation, Science, sound and light machines
Perfume Science
Learn about the sense of smell with eight perfume oils and a variety of jars, mixers, and pipettes. Experiments range from fragrance extraction to composing your own perfume scents. My friend and I enjoyed one experiment where we prepared test strips of all the fragrances and then guessed which we were sniffing. I got two […]
Chronulator PM2V
Alternative time-telling devices are compelling, but only if they’re easy to read. Building a kit can be satisfying, but only if it leaves room for creativity. The Chronulator clock kit fits the bill on both counts. Solder it together, and you’ve got a microcontroller-based clock that converts time to current, displaying hours and minutes on […]
