Humans have long admired the sound of birdsong, but to fully appreciate how technically amazing it is, you need an ultrasonic microphone. [Benn Jordan] recently created a video about using …read more Continue reading AVIF: The Avian Image Format
From the outside, iron meteorites tend to look like formless, rusted lumps of metal, which is why museums often polish and etch sections to show their interior structure. This reveals …read more Continue reading Casting Meteorite-like Materials
Most research on electroplating tries to find ways to make it plate parts more uniformly. [Ajc150] took the opposite direction, though, with his selective electroplating project, which uses an electrode …read more Continue reading Painting in Metal with Selective Electroplating
The flow battery is one of the more interesting ideas for grid energy storage – after all, how many batteries combine electron current with fluid current? If you’re interested in …read more Continue reading An Open Source Flow Battery
Although Charles Hall conducted his first successful run of the Hall-Héroult aluminium smelting process in the woodshed behind his house, it has ever since remained mostly out of reach of …read more Continue reading The Hall-Héroult Process on a Home Scale
In contrast to the success of their molten-plastic cousins, paste extrusion 3D printers have never really attained much popularity. This is shame because, as the [Hand and Machine] research group …read more Continue reading Paste Extrusion for 3D Printing Glass and Eggshells
The human eye’s color perception is notoriously variable (see, for example, the famous dress), which makes it difficult to standardize colours. This is where spectrophotometers come in: they measure colours …read more Continue reading A Spectrophotometer Jailbreak to Resolve Colorful Disputes
The old saying that the best way to learn is by doing holds as true for penetration testing as for anything else, which is why intentionally vulnerable systems like the …read more Continue reading A Vulnerable Simulator for Drone Penetration Testing
It’s an unfortunate fact that when a scientist at MIT describes an exciting new piece of hardware as “low-cost,” it might not mean the same thing as if a hobbyist …read more Continue reading A Budget Quasi-Direct-Drive Motor Inpired By MIT’s Mini Cheetah
If you’re looking for a more open, unenclosed 3D printer design than a cubic frame can accommodate, but don’t want to use a bed-slinger, you don’t have many options. [Boothy …read more Continue reading An Open-Concept 3D Printer Using Cantilever Arms
