As the 2019 mushroom foraging season approaches it’s timely to combine my thirst for knowledge about low level machine learning (ML) with a popular pastime that we enjoy here where I live. Just for the record, I’m not an expert on ML, and I’m simply inviting readers to follow me back down some rabbit holes […]
If one wants a stabilized video feed from a drone, a gimbal setup is the way to go. However, the cheaper offerings are all rather similar, suited to a certain size and type of drone. [Jean] was building a smaller craft, so set out to create his own design specifically fit for purpose. The build […]
[Julien] is one of those cool dads who shows his love with time invested rather than money spent. His daughter plays the harp, and you would not believe the price of concert harps. Even the cheap ones are several thousand USD. So naturally, he decided he would build her a MIDI concert harp from the […]
In 1984, William Gibson’s novel Neuromancer helped kick off the cyberpunk genre that many hackers have been delighting in ever since. Years before Tim Berners-Lee created the World Wide Web, Gibson was imagining worldwide computer networks and omnipresent artificial intelligence. One of his most famous fictional creations is the cyberdeck, a powerful mobile computer that […]
When [Sami Pietikäinen] realized that the Bluetooth built into his car didn’t support audio, he didn’t junk it and buy a Tesla. Instead, he decided to remedy the problem by building a small Bluetooth device that plugged into the Aux socket. To do this, he used a Raspberry Pi Zero with a pHAT DAC (Digital […]
For his entry into the 2019 Hackaday Prize, [Tobius Daichi] is working on adding some motion control capabilities to everyone’s favorite Linux SBC. His 3+Pi board attaches to the Raspberry Pi’s GPIO header and gives you a convenient way to control four individual stepper motors. Perfect for a 3D printer, laser cutter, CNC, or anything […]
Who wouldn’t want a robot that can fetch them a glass of water? [Saral Tayal] didn’t just think that, he jumped right in and built his own personal assistant robot. This isn’t just some remote-controlled rover though. The robot actually listens to his voice and recognizes his face. The body of the robot is the […]
Filming in slow-motion has long become a standard feature on the higher end of the smartphone spectrum, and can turn the most trivial physical activity into a majestic action shot to share on social media. It also unveils some little wonders of nature that are otherwise hidden to our eyes: the formation of a lightning […]
Thanks to the wonders of the internet, collaborating with others across great distances has become pretty simple. It’s easy now to share computer desktops over a network connection, and even take control of another person’s computer if the need arises. But these graphical tools are often overkill, especially if all we really need is to […]
Robotics is hard, maybe not quite as difficult as astrophysics or understanding human relationships, but designing a competition winning bot from scratch was never going to be easy. Ok, so [Paul Bupe, Jr’s] robot, named ‘Goose’, did not quite win the competition, but we’re very interested to learn what golden eggs it might lay in […]
