How-To: Variable DC Power Supply

How-To: Variable DC Power Supply

Hobbyist electronics projects need robust, reliable power supplies for prototyping and testing. I learned how to build this circuit from the Basic Analog Circuits class at ITP taught by Eric Rosenthal, but took it several steps further in building a solid enclosure and integrating a voltage meter. Now it lives on my desk, ready to power most small projects I’m working on, ranging from 0 – 24 volts and up to two amps. You can learn all about how to make one yourself using this Make: Projects tutorial.

How-To: Paper Buttons

If you’re a paper crafter, then you know how frustrating it is when you’re almost done with a project, but you just can’t find the right decorative button to pull everything together. But, with this paper button tutorial from Splitcoast Stampers, you can make your own incredibly realistic-looking buttons using a clear-drying glaze and paper […]

Arduino Shield Makes 8-Pin Chip Programming a Snap

Arduino Shield Makes 8-Pin Chip Programming a Snap

I was delighted to see the positive reaction to my latest video, Shrinkify Your Arduino Projects, which is based on a tutorial by MIT Media Lab’s High-Low Tech Group. Their tutorial walks you through the process of not only using the Arduino as a programmer for 8-pin ATtiny chips, but also how to use Arduino code and the Arduino IDE to program them. In order to make this process easier, Randy Sarafan created an Arduino shield for programming these diminutive chips. Head over to his Instructable to get the board and learn to build your own!
