Learn the basics of controlling a grid of LEDs - use one as a miniature game machine and more, as Collin Cunningham takes a look inside the LED Matrix.
Hack your remote control so that you never have to change its batteries again! Instead, just leave it in the sun to charge up! This project can be found in MAKE Volume 25.
Get acquainted with the Digital Multimeter - an engineer's best friend! Learn how to measure resistance, voltage, current as well as test continuity using the Swiss Army knife of electronics.
Give your gadgets a brain! Previously out of reach for the do-it-yourselfer, the tiny computers called microcontrollers are now so cheap and easy to use that anyone can make their stuff smart. It's called "physical computing" -- with a microcontroller, your gadget can sense the environment, talk to the internet or other gadgets, and make things happen in the real world by controlling motors, lights, or any electronic device. The Arduino is an easy-to-use microcontroller board -- it's like an R&D lab on your kitchen table for prototyping any gadget. We show you how to make one, and how to use Arduinos and other microcontrollers to make an automatic yogurt maker, a vintage Skype telephone, a gumball machine that recognizes your secret knock, and more. Plus, make a Helicopter Rocket, portable solar power pack, gourmet Sous Vide food cooker, treadmill desk, and more fun DIY projects.

Kurt Fleischer is a senior research scientist at Pixar, where he worked on building filmmaking software and directly on such films as Cars and WALL-E, before becoming a member of the research team. On his off time, he likes to apply his engineering skills to work on projects with his daughter, Lena, such as the Water Totter seen here. He used this project, which turns an old-style seesaw into a water pump, as an opportunity to teach Lena about concepts in engineering, conservation, energy generation, and a few important life lessons.
Conceived by Ben Dubin-Thaler, the Cell Motion BioBus is a self-powered mobile microscopy lab that brings hands-on science education to students in New York City lacking such resources at school. Built inside of a decommissioned San Fransisco transit bus, the BioBus runs on power from its solar panels, wind turbine, and engine burning waste vegetable oil. Students not only discover the microscopic world around them, but learn about the green tech on-board that powers the lab.
Limor Fried is the founder and engineer behind Adafruit Industries which makes electronics kits that teach soldering, tinkering, and technology exploration. One of their projects, the Tweet-a-Watt, is a wireless modification to a common off-the-shelf home energy monitor, the Kill-a-Watt. The Tweet-a-Watt not only monitors your energy consumption, it sends the information to Twitter so you can track it online, which reveals usage trends over time. Besides selling a Tweet-a-Watt kit, Adafruit has also put the open source plans online for all to freely build and share, creating a network of makers watching their usage and swapping energy-saving tips.
Sachi DeCou is a design consultant/fabricator for Sol Design Lab. The mission of the Lab is "to create interactive and inspiring solutions for urban sustainability." In that effort, they do ecological design, fabrication and consulting, ecological public art installations, carbon foot printing, and educational workshops. The SolarPump uses vintage gasoline-era technology to demonstrate the possibility of transforming unsustainable products into part of our green future. These eye-catching and innovative charging stations also serve as conversation-starters about the shift towards renewable energy and sustainable transportation options.
