In the rush to always have the latest and greatest, it’s not uncommon that perfectly serviceable hardware ends up collecting dust in a drawer somewhere. If you’ve got an old Kindle laying around, you may be interested in this write-up from [Hemant] that shows a practical example of how the popular e-reader can be pushed […]
QR codes have been with us for a long time now, and after passing through their Gardenesque hype cycle of inappropriate usage, have now settled down to be an important and ubiquitous part of life. If you have ever made a QR code you’ll know all about trying to generate the most compact and easily-scannable […]
Ground-source heat pump systems are one of the most efficient ways to do climate control, but digging the wells can be prohibitively expensive for the individual citizen. What if you could do it at a larger scale? Starting with a pilot to serve 37 commercial and residential buildings in Framingham, MA, Eversource is using its […]
Muon tomography (muography) is the practice of using muons generated by cosmic rays interacting with Earth’s atmosphere (or equivalent) to image structures on Earth’s surface, akin to producing an X-ray. In lieu of spending a lot of spending a fair bit of money on dedicated muon detectors, you can also hack such a device together […]
Camper shells are a time-honored piece of truck gear, but with modern trucks having increasingly vestigial beds, the length of your overnight abode has increasingly shrunk as well. To combat this problem, [Ed’s Garage] built a camper shell that extends once you’ve arrived at your campsite. [Ed] wanted to keep things relatively low profile while […]
This week, Jonathan Bennett and Rob Campbell talk with Shimon Schocken about Nand2Tetris, the free course about building a computer from first principles. What was the inspiration for the course? Is there a sequel or prequel in the works? Watch to find out! Nand2Tetris Did you know you can watch the live recording of the […]
Picture a football (soccer ball) in your head and you probably see the cartoon ideal—a roughly spherical shape made with polygonal patches that are sewn together, usually in a familiar pattern of black and white. A great many balls were made along these lines for a great many decades. Eventually, though, technology moved on. Footballs […]
While electric vehicles (EVs) are generally less likely to catch fire than their internal combustion counterparts, it does still happen, and firefighters need to be ready. Accordingly, the UL Research Institute is working with reverse engineering experts Munro & Associates to characterize EV fires and find the best way to fight them. There is currently […]
We’re proud to announce the last round of speakers, as well as the two workshops that we’ll be running at 2025 Hackaday Europe in Berlin on March 15th and 16th — and Friday night the 14th, if you’re already in town. The last two years that we’ve done Hackaday Europe in Berlin have been awesome, […]
Holography is about capturing 3D data from a scene, and being able to reconstruct that scene — preferably in high fidelity. Holography is not a new idea, but engaging in it is not exactly a point-and-shoot affair. One needs coherent light for a start, and it generally only gets touchier from there. But now researchers […]
