For a lot of reasons, home etching of PCBs is somewhat of a dying art. The main reason is the rise of quick-turn PCB fabrication services, of course; when you …read more Continue reading Copper Be Gone: The Chemistry Behind PCB Etching
If there’s something more tedious than winding coils, we’re not sure what it is — possibly rolling and wrapping coins; that’s really a bother. But luckily, just like there are …read more Continue reading All-Mechanical Coil Winder is a Scrap-Bin Delight
Nearly three years after the rapid unplanned disassembly of the Arecibo radio telescope, we finally have a culprit in the collapse: bad sockets. In case you somehow missed it, back …read more Continue reading Blame It on the Sockets: Forensic Analysis of the Arecibo Collapse
We mentioned last week how robotaxi provider Cruise was having a no-good, very bad week, after one of their driverless taxis picked a fight with a semi, and it was …read more Continue reading Hackaday Links: August 27, 2023
Is [William Herr]’s RPDot actually the world’s smallest RP2040 dev board? We can’t say for sure, but at 10 mm on a side, we’d say it has a pretty good …read more Continue reading RPDot: The RP2040 Dev Board Barely Bigger than the Chip
Some people hate to revisit projects that are done and dusted. We get that; it’s a little like reading a book you’ve already read when there are so many others …read more Continue reading Doppler Speed Sensor Puts FFT and AGC to Work
Guitarists will do just about anything to get just the right sound out of their setup, including purposely introducing all manner of distortion into the signal. It seems counter-intuitive, but …read more Continue reading Guitar Distortion with Diodes in Code, Not Hardware
Most of us are content to get our semiconductors from the usual sources, happily abstracting away the complexity locked within those little epoxy blobs. But eventually, you might get the …read more Continue reading Start Your Semiconductor Fab with This DIY Tube Furnace
Join us on Wednesday, August 23 at noon Pacific for the Mass Production 3D Printing Hack Chat with Gabe Bentz! We’ll take a wild guess and say that right now, …read more Continue reading Mass Production 3D Printing Hack Chat
In some ways, we’ve become a little jaded when it comes to news from Mars, which almost always has to do with the Ingenuity helicopter completing yet another successful flight. …read more Continue reading Hackaday Links: August 20, 2023
