A Lego tensegrity structure

Image
Tensegrity structures are an impressive demonstration of how to achieve mechanical stability through tensile forces. Since the topic is currently trending it was probably only a matter of time before somebody like [Alexandre Thiery] came with the idea to build a tensegrity model from Lego . In the GIF below that [Alexandre Thiery] shared on his Twitter account you can see his kids admiring the model. Tensegrity structures consist of elements under constant tension – in most cases strings – and components under compression, in this case beams of Lego. By combining these elements, one can build stable structures that seem to float in midair. A simple daily-life example for tensegrity is a balloon where the skin is the tensional element while the air inside is the component under compression. [Alexandre Thiery] has come up with the clever idea to simply clamp the strings between two Lego blocks. This certainly paves the way for other more complicated Lego-based tensegrity structures tha

Greatest Keycaps and Where to Find Them

Image
Look at your keyboard. Do the keycaps excite you? That’s what we thought. You pound on that thing day in and day out. Shouldn’t it at least be attractive? Or even happiness-inducing? You don’t necessarily have to replace every single keycap to spark joy. When it comes to artisan keycaps, the point is to have something that stands out. How about an Escape key that looks like a tall stack of flapjacks or a tiny, intricate cream puff? From a practical standpoint, how about a spiky Escape key that makes you think twice about rage quitting? If you’re into games or anime, chances are good that there are more than enough artisan keycaps out there to keep you cash-poor for a while. The same goes for scrumptious foodstuffs with Cherry MX-compatible stems. In this day and age, you can get just about any type of keycap you want, especially those encapsulating pop culture phenomena and fads. Yes there’s a fidget spinner keycap, and it’s adorable. There’s a Slight Catch (Unless You Prefer Line

Washing Your Hands with 20,000 Volts

Image
These last few weeks we’ve all been reminded about the importance of washing our hands. It’s not complicated: you just need soap, water, and about 30 seconds worth of effort. In a pinch you can even use an alcohol-based hand sanitizer. But what if there was an even better way of killing bacteria and germs on our hands? One that’s easy, fast, and doesn’t even require you to touch anything. There might be, if you’ve got a high voltage generator laying around. In his latest video, [Jay Bowles] proposes a novel concept: using the ozone generated by high-voltage corona discharge for rapid and complete hand sterilization . He explains that there’s plenty of research demonstrating the effectiveness of ozone gas a decontamination agent, and since it’s produced in abundance by coronal discharge, the high-voltage generators of the sort he experiments with could double as visually striking hand sanitizers. Looking to test this theory, [Jay] sets up an experiment using agar plates. He inoculates

Pi Cam Replaces Pinhole and Film for Digital Solargraphy

Solargraph from a one-year exposure on film. Elekes Andor / CC BY-SA Have you ever heard of solargraphy? The name tells you much of what you need to know, but the images created with a homemade pinhole camera and a piece of photographic film can be visually arresting, showing as they do the cumulative tracks of the sun’s daily journey across the sky over many months. But what if you don’t want to use film? Is solargraphy out of reach to the digital photographers of the world? Not at all, thanks to this digital solargraphy setup . [volzo] searched for a way to make a digital camera perform like a film-based solargraphic camera, first thinking to take a series of images during the day and average them together. He found that this just averaged out the sun from the final image. His solution was to take a pair of photos at each timepoint — one correctly exposed to capture the scene, and one stopped way down to just capture the position of the sun as a pinprick of light. All the foregr
