We’re tremendously excited to be able to announce that the Hackaday Supercon is on for 2025, and will be taking place October 31st through November 2nd in Pasadena, California. Supercon is about bringing the Hackaday community together to share our great ideas, big and small. So get to brainstorming, because we’d like to hear what […]
If you work with virtual machines, perhaps to spin up a clean OS install for testing, historically you have either bitten the bullet and used one of the commercial options, or spent time getting your hands dirty with something open source. Over recent years that has changed, with the arrival of open source graphical applications […]
If we asked you to think of a device that converts a chemical reaction into electricity, you’d probably say we were thinking of a battery. That’s true, but there is another device that does this that is both very similar and very different from a battery: the fuel cell. In a very simple way, you […]
Plenty of consumer goods, from passenger vehicles to toys to electronics, get tossed out prematurely for all kinds of reasons. Repairable damage, market trends, planned obsolescence, and bad design can all lead to an early sunset on something that might still have some useful life in it. This was certainly the case for a sound […]
DIY mechatronics always has some unique challenges when relying on simple tools. 3D printing enables some great abilities but high precision gearboxes are still a difficult problem for many. Answering this problem, [Sergei Mishin] has developed a very interesting gearbox solution based on a research paper looking into simple rollers instead of traditional gears. The […]
Although there are some ferries and commercial boats that use a multi-hull design, the most recognizable catamarans by far are those used for sailing. They have a number of advantages over monohull boats including higher stability, shallower draft, more deck space, and often less drag. Of course, these advantages aren’t exclusive to sailboats, and plenty […]
Regular vs gene-edited spider silk with a fluorescent gene added. (Credit: Santiago-Rivera et al. 2025, Angewandte Chemie) Continuing the scientific theme of adding fluorescent proteins to everything that moves, this time spiders found themselves at the pointy end of the CRISPR-Cas9 injection needle. In a study by researchers at the University of Bayreuth, common house […]
Don’t you hate it when making your DIY X-ray machine you make an uncomfortable amount of ozone gas? No? Well [Hyperspace Pirate] did, which made him come up with an interesting idea. While creating a high voltage supply for his very own X-ray machine, the high voltage corona discharge produced a very large amount of […]
Some readers may recall building a line-following robot during their school days. Involving some IR LEDs, perhaps a bit of LEGO, and plenty of trial-and-error, it was fun on a tiny scale. Now imagine that—but rideable. That’s exactly what [Austin Blake] did, scaling up a classroom robotics staple into a full-size vehicle you can actually […]
This week, Jonathan Bennett and Jeff Massie chat with Tom Herbert about eBPF, really fast networking, what the future looks like for high performance computing and the Linux Kernel, and more! https://medium.com/@tom_84912 Did you know you can watch the live recording of the show right on our YouTube Channel? Have someone you’d like us to […]
