This week, I have been mostly working on...

I've been tinkering around with bits of technology since I was five years old. I used to take the telephone apart at home, just to see how it worked.

After a couple of years I could even put it back together again - and sometimes it would continue to work.

Learn how to use solar panels for both battery charging and for sensing when light has dropped below a certain threshold. Learn how to use an Arduino Micro for power management, and combine these two skills into an exciting classic "cricket" noisemaker that only turns on when the sun has... Read more »

This project is not so much a step-by-step guide, but more of an idea. Sometimes buying something is not really the best thing to do. I have a lot of electronic test equipment and I could not find a reasonably priced desk or bench that would put everything within easy... Read more »

A data logger is a device that is left to run for long periods of time, making regular measurements of external sensors. We’ll be using the Arduino microcontroller and a homemade "shield" (an Arduino accessory board) to create a device that gathers data on light-brightness in an area and how... Read more »

In this project, we’ll take a very simple idea — the length of time it takes a capacitor to charge — and make something rather amazing with it: a 3D interface that can track the position of your hand. The original implementation of this project comes from media artist Kyle... Read more »

Crystal radio technology has been around for many years. This "bottle radio" take on a crystal radio requires no power source, operates on the power from radio waves, and receives signal from a long wire antenna. As radio stations slowly move away from the AM band, the "window of opportunity"... Read more »

In this project we’re going to take inspiration from Len Keeler’s original Elastic String Bass. We’ll pick it up (no pun intended) and run with it, adding multiple strings for different tonal qualities, etch our own printed circuit board (PCB), and of course, demonstrate the instrument. First we will breadboard... Read more »

With an estimated one billion 555 timers manufactured annually, you know this component must be versatile! We’re going to learn how to build and control drivers for three very different types of motors using a breadboard, resistors, diodes, transistors, and some 555 timers (along with a sprinkling of CMOS logic)....
