There are many forms of human interface device beyond the ubiquitous keyboard and mouse, but when it comes to fine-tuning a linear setting such as a volume control there’s nothing quite like a knob. When it comes to peripherals it’s not the size that matters, as proven by [Stefan Wagner] with the Tiny Knob. It’s […]
A team at Google has spent a lot of time recently playing table tennis, purportedly only for science. Their goal was to see whether they could construct a robot which would not only play table tennis, but even keep up with practiced human players. In the paper available on ArXiv, they detail what it took […]
If you make anything that moves, like a robot, you quickly realize that turning can be a pain. That’s why there are a number of designs for wheels that can go in different directions. One of the most common is the mechanum wheel. [Jeremy] explains how they work by filming them from below on a […]
The Proxxon MF70 mini-mill is a cheap and cheerful, but decently made little desktop mill. As such, it’s been the target of innumerable CNC-ification projects, including an official kit from the manufacturer. But that didn’t stop [Dheera Venkatraman] from sharing his Big Yellow take on this venerable pursuit with us! This isn’t simply a CNC […]
Beta thalassemia and sickle cell are two red blood cell disorders which both come with massive health implications and shortened lifespans, but at least for UK-based patients the former may soon be curable with a fairly new CRISPR-Cas9 gene therapy (Casgevy) via the UK’s National Health Service (NHS). Starting with the NHS in England, the […]
Unfortunately, [Dave Niewinski]’s kids are still too little to go on a real roller coaster. But they’re certainly big enough to be tossed around by this giant robot arm roller coaster simulator. As to the question of why [Dave] has a Kuka KR 150 robot in his house, we prefer to leave that unasked and […]
Printing a model jet engine is quite an accomplishment. But it wasn’t enough for [linus3d]. He wanted to redesign it to have a turbojet, an afterburner, and a variable exhaust nozzle. You can see how it all goes together in the video below. This took months of work and it shows. This probably won’t make […]
The QN8066 is a fun little FM transmitter chip. It covers the full FM broadcast band and has built-in DSP. You would find this sort of part in car cell phone adapters before every vehicle included Bluetooth or an AUX port. [Ricardo] has created an Arduino library to bring the QN8066 to the masses. The […]
Hackaday’s own [Arya Voronova] has been on a multi-year kick to make technology more personal by making it herself, and has just now started writing about it. Her main point rings especially true in this day and age, where a lot of the tech devices we could use to help us are instead used to […]
It’s been an ongoing issue for years now. People who buy video games, especially physical copies, expect to be able to play that game at their leisure, no matter how old their console gets. This used to be a no-brainer: think about the SNES or Genesis/Mega Drive from the late 80s and early 90s. You […]
