Wind Lantern

Wind Lantern

In this project, we’ll build a small, vertical-axis wind turbine, or VAWT for short. These are not as efficient as their horizontal-axis cousins, but they are better suited to urban environments where wind can come from all different directions. Normally, when you give electricity to a motor, it spins. The same is true in reverse: […]

Get Started with Arduino Clones

Get Started with Arduino Clones

Here you will learn how to wire the Arduino clone up and how to start your first project. In this tutorial, I am working with a breadboardable ATMega Lite Dev Kit from SurplusGizmos.com, but this can apply to other Arduino clones, too, such as the Ardweeny kit in the Maker Shed. Note: this tutorial is […]

Build a projBox Controller

Build a projBox Controller

The finished projBox controller provides physical inputs for your software in addition to the computer’s conventional keyboard and mouse. The combination of open-source enclosure schematics and the use of standard electronic components provides an infinitely customizable prototyping platform. The projBox is specifically designed to integrate with software written in Processing, the IDE that the Arduino’s […]

Yobot: Arduino Yogurt Maker

Yobot: Arduino Yogurt Maker

I’m lazy. My impatience often leads me to botch important steps when I make yogurt. So to get better control over the fermentation process, I made a crockpot thermostat attachment to precisely control the temperature. You can buy electric yogurt makers, but most of them only incubate; the heating/sterilization step still has to be done […]

Tweet-A-Watt Power Monitor

Tweet-A-Watt Power Monitor

By Limor Fried and Phillip Torrone We live in a rented apartment, so we don’t have hacking access to a power meter or breaker panel. But we still wanted to measure our household power usage long-term, so we developed the Tweet-a-Watt. It uses plug-in electricity monitors at each outlet to wirelessly send readings to a […]
