Oven modified with ControLeo2

Peter Easton and Gary Tietz are both semi-retired engineers, but still enjoy tinkering with software and hardware projects in their spare time. Together they set out to solve a big challenge for those designing small form factor electronics boards: soldering surface mount components. Soldering Techniques There are two basic approaches...

Glue Motors using a TRS port to control two servo motors

One of my favorite aspects of editing projects at Make: is seeing how other people approach technology. It’s truly energizing to see someone use a basic component in a way you’d never think of doing yourself. Such an experience is exactly what happened when I first saw Kazu Terasaki’s GlueMotor...

Arduino MEGA

In the spirit and celebration of Arduino Day, we’ve compiled a list of some great past projects for your enjoyment. While the Arduino UNO and older Duemilanove are two of the most common Arduino boards, the MEGA and the Yún should not be avoided. The MEGA is much like the... Read more »

Raspberry Pirate Radio

This simple hack turns your Raspberry Pi into a powerful FM transmitter! It has enough range to cover your home, DIY drive-in movie, a high school ball game, or even a bike parade (depending on the stragglers).

The Raspberry Pi is a great platform to rapidly build fun electronics projects. And since it’s Pi Day here in the States —yes, we really do order the date by month/day/year, 3/14/15— we thought it’s a great time to share thirteen of our favorite Pi projects. This collection of projects... Read more »

The new Spark Electron

Meet Electron from Spark, the new board that puts GSM cellular connectivity directly on the microcontroller. With its onboard cellular antenna, this diminutive board will offer a huge range of deployment options and alleviate the hassle of using a custom cellular breakout board with your micro controller projects. They’re offering two... Read more »


The tiny, powerful Intel Edison platform has been a bit difficult to interface with. But now two new breakout boards from DFRobot vie to become the robotics community’s must-have Edison connection. Since its debut a few months ago, the most common ways to work with Edison are two breakout boards available from Intel and the... Read more »
