Nixie tubes are adored by hackers across the world for their warm glow that recalls an age of bitter nuclear standoffs and endless proxy wars. However, they’re not the easiest thing to drive, requiring high voltages that can scare microcontrollers senseless. Thankfully, it’s possible to score an Arduino shield that does the heavy lifting for […]
Interfering with radio communications, whether through jamming, deauthing attacks, or other meddling, is generally considered a crime, and one that attracts significant penalties. However, studying such techniques should provide a useful edge in the electronic wars to come. In this vein, [Giorgio Filardi] has recently built a WiFi deauther the size of a credit card. […]
A word of warning: Google for the definition of the word “pummer” at your own risk. Rest assured that this beautiful solar-powered circuit sculpture fits the only definition of pummer that we care to deal with. For the unfamiliar, a pummer is a device from the BEAM style of robotics, a sort of cyborg plant […]
It wouldn’t be much of a stretch to assume that anyone reading Hackaday regularly has at least progressed to the point where they can connect an LED to a microcontroller and get it to blink without setting anything on fire. We won’t even chastise you for not doing it with a 555 timer. It’s also […]
Just like how vinyl records are seeing a resurgence in an era of digital streaming music, we’re also seeing a lot of people interested in another technology that is as obsolete as it is perfected. The large format camera is back as a kit, it makes huge images, and there’s an Open Source version if […]
If you keep up with the field of web development, you may have heard of WebAssembly. A relatively new kid on the block, it was announced in 2015, and managed to garner standardised support from all major browsers by 2017 – an impressive feat. However, it’s only more recently that the developer community has started […]
Graphing calculators are an interesting niche market these days. They’re relatively underpowered, and usually come with cheap, low resolution screens to boot. They remain viable almost solely due to their use in education and the fact that their limited connectivity makes them suitable for use in exams. The market is starting to hot up, though […]
We’ve seen a lot of arcade machine builds here on Hackaday. Seriously, a lot. Even more so since the Raspberry Pi took over the world and made it so you didn’t have to cannibalize an old laptop to build one anymore. It’s one of those projects with huge appeal: either you’re somebody who’s built their […]
In these days of cheap microcontrollers, it is hard to remember there was a time when timing things took real circuitry. Even today, for some applications it is hard to beat the ubiquitous 555 timer IC. It is cheap, plentiful, and reliable. What’s interesting about the 555 is it isn’t so much a dedicated chip […]
