When it comes to polarizing and confusing questions in electronics, wiring up shields is on the top-10 list when sorted by popularity. It’s a question most of us need to figure out at some point – when you place a USB socket symbol on your schematic, where do you wire up the SHIELD and MP […]
It’s Friday the 13th, and despite having to dodge black cats and poorly located ladders, Elliot and Dan were able to get together and run down the best hacks of the first week of September. Our luck was pretty good, too, seeing how we stumbled upon a coffee table that walks your drink over to […]
There’s a good chance you’ve seen “Nixie clocks” on the Internet that replace the classic cold cathode tubes with similarly sized LCD panels. The hook is that the LCDs can show pictures and animations of Nixie tubes — or pretty much anything else for that matter — to recreate the look of the real thing, […]
It’s time to talk about Microsoft’s patch Tuesday, and the odd vulnerability rollback that happened. CVE-2024-43491 has caught some attention, as it’s a 9.8 on the CVSS scale, is under active exploitation, and results in Remote Code Execution (RCE). Yikes, it sounds terrible! First off, what actually happened? The official statement is that “build version […]
MIDI is normally baked into the chipset of a synthesizer, or something you use a microcontroller to handle. But that’s not the only way to speak the language! [Kevin] decided to have some fun doing MIDI with discrete logic instead, with some pretty neat results. [Kevin] had previously built a control voltage step sequencer called […]
These days, PCB fab houses are just about everywhere, and you can’t go buy a taco without walking past eight of them. Still, some out there still like to etch their PCBs at home. If that sounds like you, you might see some value in [Chris Borge]’s PCB agitator. The design mostly relies on 3D […]
Nixie tubes are cool, and hackers like them. Perhaps for those reasons more than any other, [Kevin Santo Cappuccio] has developed a very particular Simple Add-On for the 2024 Hackaday Supercon badge. Rad, no? The build began with a Burroughs 122P224 Nixie tube, and a HV8200 power supply. The latter component is key—it’s capable of […]
QR codes are used just about everywhere now, for checking into venues, ordering food, or just plain old advertising. But what about data storage? It’s hardly efficient, but if you want to store your files in a ridiculous paper format—there’s a way to do that, too! QR-Backup was developed by [za3k], and is currently available […]
When you work with tiny things on the regular, they start to seem normal-sized to your hands and eyes. Then, if you work with even smaller packages, stuff like 0603 might as well be through-hole components. [alnwlsn] is no stranger to the small, having worked almost exclusively with surface mount components for a few years […]
Bumper stickers are usually political, crude, or otherwise inflammatory. Rather a more fun example is this digital creation from [Guy Dupont], who made a bumper sticker that broadcasts what he’s listening to on the stereo. [Guy] found a nice wide 11-inch bar LCD that was the right aspect ratio to suit the “bumper sticker” aesthetic. […]
