Brain-to-speech interfaces have been promising to help paralyzed individuals communicate for years. Unfortunately, many systems have had significant latency that has left them lacking somewhat in the practicality stakes. A team of researchers across UC Berkeley and UC San Francisco has been working on the problem and made significant strides forward in capability. A new system […]
Rear-view mirrors are important safety tools, but [Mike Kelly] observed that cyclists (himself included) faced hurdles to using them effectively. His solution? A helmet-mounted dual-mirror system he’s calling the Mantis Mirror that looks eminently DIY-able to any motivated hacker who enjoys cycling. One mirror for upright body positions, the other for lower positions. Carefully placed […]
One might be tempted to think that re-creating a film robot from the 1950s would be easy given all the tools and technology available to the modern hobbyist, but as [Mike Ogrinz]’s quest to re-create Robby the Robot shows us, there is a lot moving around inside that domed head, and requires careful and clever […]
Vintage hi-fi gear has a look and feel all its own. [ThunderOwl] happened to be playing in this space, turning a heavily-modified Technics stereo stack into an awesome neo-retro PC case. Meet the “TechnicsPC!” This is good. We like this. You have to hunt across BlueSky for the goodies, but it’s well worth it. The […]
Radiation-induced volumetric expansion (RIVE) is a concern for any concrete structures that are exposed to neutron flux and other types of radiation that affect crystalline structures within the aggregate. For research facilities and (commercial) nuclear reactors, RIVE is generally considered to be one of the factors that sets a limit on the lifespan of these […]
Typewriters aren’t really made anymore in any major quantity, since the computer kind of rained all over its inky parade. That’s not to say you can’t build one yourself though, as [Toast] did in a very creative fashion. After being inspired by so many typewriters on YouTube, [Toast] decided they simply had to 3D print […]
Most of us learned to design circuits with schematics. But if you get to a certain level of complexity, schematics are a pain. Modern designers — especially for digital circuits — prefer to use some kind of hardware description language. There are a few options to do similar things with PCB layout, including tscircuit. There’s […]
This week, Jonathan Bennett and Dan Lynch chat with Peter van Dijk about PowerDNS! Is the problem always DNS? How did PowerDNS start? And just how big can PowerDNS scale? Watch to find out! https://github.com/PowerDNS/ https://github.com/Habbie https://github.com/voorkant/ https://7bits.nl/journal/ Did you know you can watch the live recording of the show right on our YouTube Channel?

Smart glasses are a complicated technology to work with. The smart part is usually straightforward enough—microprocessors and software are perfectly well understood and easy to integrate into even very compact packages. It’s the glasses part that often proves challenging—figuring out the right optics to create a workable visual interface that sits mere millimeters from the […]
One of the first things that an amateur radio operator is likely to do once receiving their license is grab a dual-band handheld and try to make contacts with a local repeater. After the initial contacts, though, many hams move on to more technically challenging aspects of the hobby. One of those being activating space-based […]
