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.
Red Blinky POV
This kit is amazingly cool and easy to use. POV (persistence of vision) displays show words or patterns that seem to float in mid-air; if you’ve ever seen one, you know what a great effect it is. A line of LEDs flashes the Y component of what you’re displaying, and you provide the X by […]
Mozzarella Cheese Kit
I would happily eat my weight in cheese, so the idea of having fresh mozzarella whenever I want has very strong appeal. This kit makes it as easy as buying a gallon of (not ultra-pasteurized) milk. The clear instructions take any mystery out of the chemistry, and I went from hot milk to perfect curds […]
Getting Started with Arduino Kit v3.0
The world of Arduino microcontrollers can be a challenge to break into — but not if you’re equipped with this kit, which includes all of the hardware you need to work through each of the experiments in Getting Started with Arduino, the popular introductory book by Arduino project co-founder Massimo Banzi. To make it even […]

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. […]
Diesel to Veggie Car Conversion
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.) […]
Elekit TU-879S Stereo Tube Amplifier
The great thing about this kit is the variety of skills you’ll learn. Not only do you end up with a warm-sounding tube amp, but you also learn how all these audio components are produced, as well as proper soldering technique, orientation of polarized capacitors, spacing of large-value wirewound resistors, and heat sinking of transistors. […]
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 […]
Corned Beef and Pastrami Kit
I’ve made corned beef every St. Paddy’s day for years now, and have finally perfected my cocktail of pickling spices. Turns out I could have just gotten Leeners’ Corned Beef and Pastrami Kit; theirs is just as good. The kit comes with absolutely everything you need except the brisket (including a scarily effective meat tenderizer), […]

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) […]

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 […]
