[Editor’s note: This video disappeared, but there’s another version here at the moment. We’re leaving the links as-were in case they come back up soon.] The aptly named [LightingOnDemand] has created a Lorentz cannon that can fire a lightning bolt. Honestly, as you can see in the video below, it looks like something from a […]
Like the lead paint and asbestos of decades past, microplastics are the new awful contaminant that we really ought to do something about. They’re particularly abundant in the aquatic environment, and that’s not a good thing. While we’ve all seen heartbreaking photos of beaches strewn with water bottles and fishing nets, it’s the invisible threat […]
You know, it’s a tale as old as custom mechanical keyboards. [penkia] couldn’t find any PCBs with 36 keys and Gateron low-profile switch footprints, so they made their own and called it the LoremIpsum36. Isn’t it lovely? This baby runs on an RP2040, which sits flush as can be in a cutout in the PCB. […]
While we aren’t heavy-duty woodworkers, we occasionally make some sawdust as part of a project, and we admire people who know how to make wood and do what they want. We were surprised when [Newton Makes] showed a wooden dowel that was quite long and was mostly hollow. The wall was thin, the hole was […]
A PCB ruler is a common promotional item, or design exercise. Usually they have some sample outlines and holes as an aid to PCB design, but sometimes they also incorporate some circuitry. [Clovis Fritzen] has given us an ingenious example, in the form of a PCB ruler with a built-in thermometer. This maybe doesn’t have […]
If you’re like most makers, you have a few product ideas kicking about, but you may not have made it all the way to production of those things. If you’re thinking about making the leap, [Simone Giertz] recently discussed all the perils and pitfalls of the process from idea to reality. The TLDR is that […]
Before the digital age, when transistors were expensive, unreliable, and/or nonexistent, engineers had to use other tricks to do things that we take for granted nowadays. Motor positioning, for example, wasn’t as straightforward as using a rotary encoder and a microcontroller. There are a few other ways of doing this, though, and [Void Electronics] walks […]
Mick Jagger famously said that you cain’t always get what you want. But this is Hackaday, and we make what we want or can’t get. Case in point: [Andrew Tudoroi] is drawn to retro LEDs and wanted one of Pimoroni’s micro-LED boards pretty badly, but couldn’t get his hands on one. You know how this […]
This week, Jonathan Bennett talks Session and cryptocurrency skepticism with Kee Jefferys! Why fork Signal? How does Session manage to decentralize? And why the cryptocurrency angle? Listen to find out! https://getsession.org/ https://github.com/oxen-io/ Did you know you can watch the live recording of the show right on our YouTube Channel? Have someone you’d like us to […]
