Most of the commercially-available pet feeders littering the internet are cheaply-made, with wimpy motors and infuriating interfaces. Want to use it outdoors? Good luck. If you need a heavy-duty, outdoor cat feeder, you gotta heat up your soldering iron and do it yourself. [jplanaux] is under contract to feed a bunch of feral cats that […]
Portrait painting is, by and large, a human endeavour. But, like any and all skills, there are machines ready and willing to take a crack at it. [Jose Salatino] has built just such a machine, and the results are impressive. Samples of the artwork created by [Jose’s] portrait painter. [Jose’s] portrait painter relies on a […]
The tickets have sold out even as the list of incredible speakers grows. Today we bring you the third dose of talks you’ll see at the Hackaday Superconference in November — whether you were lucky enough to grab a ticket, or will be watching the livestream, these eight will be speaking on topics from algorithmically-augmented […]
Hackaday Editors Elliot Williams and Mike Szczys recap a week full of hacks from the solar sailing RC plane that has zero power storage, to geeking out about lightning detectors and hacking Ikea LED controllers to unlock real dimming to building backyard wind turbines. We look up an IoT egg tray with appreciation not for […]
Speaker cone materials can be a deep rabbit hole ranging from inexpensive paper to kevlar. We’ve all cut apart, or blown out, the cheapies to see their inner workings, but the exotic material list does not stop at audiophile-quality models. It can include mirrors, microwave ovens, and a European hacker’s forehead. Video also after the […]
A bug was recently fix in Signal that allowed a caller to force a call connection without any user interaction on the receiving side. We’ve seen this sort of problem in other chat applications, most recently the Zoom debacle. The Signal client uses the same function to connect an outgoing call as an incoming call. […]
Just two weeks ago, the crew from the International Space Station released a photo of their nine crew members – an odd number considering that the facility only has space to house six astronauts at a time. In fact, the crew had just gathered for a celebratory dinner before three of the astronauts were to […]
If you ask people how they rate as a driver, most of them will say they are better than average. At first, that seems improbable until you realize one thing: people judge themselves by different criteria. So Sally thinks she’s a good driver because she goes fast. Tom’s never had a wreck. Alice never gets […]
Do you have a Raspberry Pi? What is it being used for right now? If you’re like the majority of people who replied to [Michael Hall’s] poll on Twitter, it’s likely yours is sitting on a shelf doing nothing too. So why not just turn it into an IoT device for your home? [Michael] wrote […]
There’s no question that surface-mount technology has been a game-changer for PCB design. It means easier automated component placement and soldering, and it’s a big reason why electronics have gotten so cheap. It’s not without problems, though, particularly when you have no choice but to include through-hole components on your SMT boards. [James Clough] ran […]
