[Video Link] Here's MAKE's latest weekend project - two solar-powered BEAM bots. BEAM stands for Biology, Electronics, Aesthetics, and Mechanics. From Wikipedia: "This is a term that refers to a style of robotics that primarily uses simple analogue circuits, such as comparators, instead of a microprocessor in order to produce an unusually simple design (in comparison to traditional mobile robots) that trades flexibility for robustness and efficiency in performing the task for which it was designed."
The Solar Roller and Symet both use the same circuit design, dubbed “solar engine,” named so for deriving its energy from solar light. With various technoscrap parts — we salvaged ours from an old micro-cassette player – and common components (transistors, resistors, LED, and capacitors) hooked up to a solar cell, you can build one of these little critters!
The Solar Roller move forward with bursts of energy, while the Symet spins around on its DC motor’s axle. Watch the video above to see both these vehicle being built and in action, then head over to the project page to start making your own BEAM critters!
The office I work in is full of things old people buy to make themselves feel young again. I can honestly say that our awesome new toy, The Swagtron T3 Hoverboard, makes me feel very, very old. I’ll explain why later. Swagtron T3 Pros There’s no way to overcharge the battery and that means no […]
One thing that’s consistent among amateur pool players is that they unknowingly stand up during their shots. Just as in golf, pool players need to keep their heads down and stay still after they shoot in order to hit straight. The DIGICUE helps keep shots consistent by letting you know every time you’ve had extra […]
A leaked memo from Apple CEO Tim Cook to his staff explaining why he met with Donald Trump — a guy who called Apple traitors for refusing to defeat their own security — explains the rationale: “tax reform.”

The 2016 World Series game 7 will undoubtedly go down in history as one of the greatest baseball games of all time. With endless suspense, a nefariously-timed rain delay, and extra innings, it reminded over 40 million viewers why they love America’s pastime – and why all bets were truly off in 2016. Savor the […]
