Kit Completeness: 4
(5=Most complete) How complete is the kit? Plans only? That rates a 1. Parts bundles and kits rate 2–5, depending on whether it’s just key components, almost every- thing, or absolutely everything you need, including any unusual tools.
The Truth Meter
See what happens when someone asks you questions or when you laugh or get surprised. Everyone responds differently. See if you can turn the LED on with your mind. Try it on your friends or adversaries — it’s a great way to get to know someone! We’ve even included a few extra resistors, so you […]
Reinventing Edison: Light Bulb Kit
Thomas Edison purportedly said that he didn’t fail 700 times in trying to make the incandescent light, he succeeded in proving 700 ways not to do it. Now it can be your turn. This fun science kit is designed to excite and engage experimenters of all ages in re-creating the development of the first light […]
Analog Geiger Counter
MAKE contributor John Iovine has been designing and improving affordable Geiger counters for decades. After Japan’s nuclear crisis last spring, his company was swamped with orders. Now they’re working on even better designs and DIY kits. This analog counter detects beta radiation above 36 kilo-electron volts (keV) and gamma above 7keV, signaling each radioactive particle detected with an […]
Laser Voice Transmitter and Receiver
This amazing demo shows how you can transmit sound over a laser beam. The transmitter modulates power to a laser pointer with audio from a headphone jack. The receiver is just an earphone and a solar cell; no power source. I assembled both in minutes, and it was strange (in a good way) to hear music […]
Energy Wiz
Aimed at kids 8 and up, this kit has real heart. Its 48-page workbook and components (solar cell, buzzer, two motors, LED, capacitor, copper rivets, pinwheel, etc.) take you through lessons and fun experiments that teach the basics: What is energy, as distinct from force? What forms does it take? How can it be converted […]
PumLantern Kit
This kit includes everything needed to build a solar-charged, nighttime-activated, light-pulsing lamp. It charges all day from the SCC3733 solar cell, and “pumms” the four ultra-mega-super-bright LEDs to cast artistic silhouettes against the walls of the stylized cardboard lantern. The LEDs are a random grab of white, blue, red, orange, and green. Basic soldering is […]
Fire Pit Kit
Blacksmith/sculptor Jon Sarriugarte of Form & Reform makes magical propane-powered fire pits. As he puts it, “Not only do they give off warmth but you can entertain your guest with drawings in the sand that burn where you draw!” You can buy one ready-made, or pick up one of his fire pit kits to make […]
Chofu Wood-Fired Hot Tub
The Chofu is a very simple, and very beautiful, DIY wood-fired hot tub heater. It looks like a potbellied stove with an Eastern aesthetic, and it comes from Japan. Any container that’ll hold water can be the hot tub (metal stock tanks are a great choice). The stove is connected to the tub by two […]
Bulbdial Clock
The Bulbdial Clock displays analog time, without any motor, movement, or screen. The 72 LEDs cast shadow hands across its face, with red, green, and blue for hours, minutes, and seconds. It’s a beautiful effect, and the kit is not difficult to assemble, thanks to incredibly well-done instructions.
Edo-Style Clock
I had a great time building the Edo-Style clock kit from Gakken, and was amazed at its accuracy over several months of use. The kit is well designed, durable, and fun. The included picture-based directions are easy to follow, even if you don’t know Japanese, but if you plan to make one, you can also refer […]
