Brew a cup of this popular "tea of immortality," and enjoy its healthy, fermented zing. A flashback from the pages of CRAFT.
Try these clever off-label uses for an underappreciated component. There are billions of triacs in the world. In almost every lamp dimmer, every electric stove, and many motor controllers, power is moderated by a triac clipping a portion of each positive and negative AC pulse.
Can humans fly by flapping? Nope. But they can build a small, rubber band-powered ornithopter whose motion is similar to a bird in flight. Here's how! A classic project from William Gurstelle from the pages of MAKE Volume 08.
We're learning how to use EAGLE by stepping through the design process for a basic Arduino-type AVR microcontroller development board, specifically the Really Bare Bones Board design by Paul Badger of Modern Device. In Part 1, we showed you how to lay out the schematic and validate it with EAGLE's built-in Electrical Rule Check. Here we'll show you how to establish the physical shape of the board and the actual copper pathways that make up the real circuit.
Tired of all those LCD TVs everywhere?
With the right parts list and a simple plan, you can have this built in just eight hours for under $1,000.
Step-by-step instructions for making (and unmaking) the perfect solder joint.
Since an electromagnetic telephone receiver can double as a microphone, can a semiconductor light emitting diode (LED) double as a light detector?
It’s loud, annoying, and fun — cut out the parts on a CNC router, then motorize them with a cheapo bench grinder (we found the perfect one at Harbor Freight). A great CNC project from MAKE fabricator Dan Spangler, designed with a traditional 5/6 two-tone sound ratio like the classic World War II sirens. WEEEEEEEEEEEOOOH!
Use data loggers and DIY sensors to map temperatures where you live. Towns are hotter than countryside, parking lots are scorching compared to green fields — what else can you discover? Another great amateur science project from Forrest M. Mims III, who shows you how to build and mount simple sensors and then deploy them on cars to take mobile transects, then use the data to create temperature maps.
Keep your pet happy and hydrated with this simple build.
With this portable and inexpensive launcher, even the youngest kids can achieve impressive flights with the Rocket Glider from MAKE Volume 31.
