It’s the moment you hard-core hardware nerds have been waiting for: the reveal of the 2025 Hackaday Supercon Communicator Badge. And this year, we’ve outdone ourselves, but that’s thanks to help from stellar collaboration with folks from the community, and help from sponsors. This badge is bigger than the sum of its parts, and we’ve […]
Compared to the old 8-bit Arduinos, it’s incredible how cheap modern microcontrollers like the ESP32 have become. But there are even cheaper options out there if you don’t need that kind of horsepower, and are willing to do a little work yourself, as [atomic14] demonstrates. The CH32V003 is a dirt cheap microcontroller—which can reportedly be […]
Having a gadget’s battery nestled snugly within the bowels of a device has certain advantages. It finally solves the ‘no batteries included’ problem, and there is no more juggling of AA or AAA cells, nor their respective chargers. Instead each device is paired to that one battery that is happily charged using a standardized USB […]
Unless you are over a certain age, you probably take it for granted that electronic gadgets you buy have some FCC marking on them. But it wasn’t always true. [Ernie] submits that the FCC’s regulation of the computer industry was indirectly the result of the success of CB radio in that same time period. Today, […]
The Unihiker K10 is intended to be a small single-board solution for light AI and machine learning tasks. However, you don’t have to use it in that way if you don’t want to. [mircemk] figured out how to repurpose the device, and whipped up a simple Internet clock build to demonstrate how it’s done. While the […]
Obsolete hardware is all around us, and some of it has some pretty interesting tech buried within. One such device is an old Belgacom TV Box. Instead of using the ubiquitous LCD screen, it uses a VFD display for its user interface, and [Jean] has taken control of it with the ESPTimeCastVFD project. Inside this […]
Although nuclear fusion is exceedingly easy to achieve, as evidenced by desktop fusors, the real challenges begin to pop up whenever you try to sustain a plasma for extended periods of time, never mind trying to generate net energy output. Plasma instability was the reason why 1950s UK saw its nuclear fusion hopes dashed when […]
Tinkercad is famous for having lots of colors in the interface. But once you export an STL, that file is notoriously monochrome. If you are printing with a single color printer, no problems. But if you have a color printer, what do you do? [CHEP] shows some options, including a relatively new one, in the […]
The cool thing about building your own computer is that you don’t have to adhere to industry norms of form and function. You can build whatever chunky, awesome thing your heart desires, and that’s precisely what [Rahmanshaber] did with the MutantC cyberdeck. The build is based around a Raspberry Pi Compute Module 4. If you’re […]
