[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!
Where are our petabyte drives? Brian Hayes takes us through the reasons storage is “stuck” in the low terabytes. The tl;dr is that we got such exceptional capacity growth in the late 90s and early 00s we don’t need much more right now, so the focus since then has been on SSDs, networking, interfaces, etc, […]
Amélie Lamont, a former staffer at website-hosting startup Squarespace, writes that she often found herself disregarded and disrespected by her colleagues. One comment in particular, though, set her reeling — and came to exemplify her experiences there.
In this episode of the Flash Forward podcast we travel to a future where humans have decided to eradicate the most dangerous animal on the planet: mosquitos. How would we do it? Is it even possible? And what are the consequences? Flash Forward: RSS | iTunes | Twitter | Facebook | Web | Patreon We […]
Almost everyone has their smartphone in a case of one kind or another. Beyond simple protection, finding a case that can charge your phone on its own, but doesn’t feel like it’s also adding a couple pounds to the phone’s weight is the tricky part. Billed as the world’s thinnest battery case, the ThinCharge iPhone […]
You never know when new projects, ideas or opportunities can drop into your lap at a moment’s notice. That may require you to learn a new programming language like Python. Or maybe you need a primer on 3D game development. Or you might realize you could use a serious brush-up on iOS mobile creation.Point is, […]
Isn’t it about time to stretch what your Mac can do? I mean, you’ve got plenty of great programs now…but don’t you think you could use some new tools to get your creative, analytical and organizational juices really flowing? It’s spring, so we cleaned up a whole bunch of super-cool apps lying around and packaged […]
