For many environmental enthusiasts, horizontal-axis wind turbines (HAWTs) — the kind that look like windmills slowly spinning in the distance — are a pretty familiar sight. Unfortunately, there are quite a few caveats that make them harder to adopt despite the fact that harvesting renewable energy sources is more sustainable than relying on natural gas […]
One of the step changes in electronic construction at our level over the last ten or fifteen years has been the availability of cheap high-quality printed circuit boards. What used to cost hundreds of dollars is now essentially an impulse buy, allowing the most intricate of devices to be easily worked with. Many of us […]
The internet is awash with millions of stunning LED projects, and for that, we are all very thankful. For those outside the hacker/maker matrix, it can be difficult to know how to approach such a build. Never fear, for [Amy Goodchild] has put together a beginner’s guide to building pretty glowables, using Fadecandy and Processing. […]
For many people, a retrocomputer is a classic machine from the past lovingly brought back to working order. But for some, the idea of a retrocomputer is wider than that, encompassing modern hardware that delivers to feel like a device from the past. The Monotron from [Jonathan Pallant] is one such computer. It’s definitely a […]
Anyone who has travelled to distant mountain peaks has marvelled at the beauty of the natural, rugged terrain. [apoorvas15] is no different, and created a lamp that celebrated the awe of the largest mountain on earth. When it comes to reproducing an accurate geometrical representation of the landscape, the easiest approach is to reach for […]
Sometimes one just needs an extra hand or six  around the workbench. Since you’re a hacker that should take the form of a tiny robot swarm that can physically display your sensor data, protect you against a dangerously hot caffeine fix and clean up once you’re done. [Ryo Suzuki] and [Clement Zheng] from the University […]
[Design Prototype Test] got a box in the mail. Inside? An E3D “tool changer and motion system.” Superficially, it looks like a 3D printer, but it is touted as a machine that can mount several different kinds of tools, including a 3D print head. In the video below, you can see the assembly of the […]
Controlling a single drone takes up a considerable amount of concentration and normally involves wearing silly goggles. It only gets harder if you want to control a swarm. Researchers at Skolkovo Institute of Technology decided Jedi mind tricks were the best way, and set up swarm control using hand gestures.  We’ve seen something similar at […]
