[Remy van Elst] found an obsolete bike navigation system, the Navman Bike 1000, in a thrift store for €10. The device was a rebadged Mio Cyclo 200 from 2015. Can a decade-old GPS be useful? Well, the answer depends on a little reverse engineering. There were some newer maps available, but they wouldn’t download using […]
You can get cheap no-brand macropads for almost nothing now. Some of them have just a couple of keys. Others have lots of keys, knobs, and LEDs. You can spring for a name brand, and it’ll be a good bet that it runs QMK. But the cheap ones? Get ready to download Windows-only software from […]
Setting up a file server can be intimidating to the uninitiated. There are many servers to choose from, and then you need to decide how to install it — Docker? Kubernates? Well, what’s all that then? [9001] has come to the rescue with Copyparty, a full-featured file server in a single Python script. It’s light […]
We like cyberdecks here at Hackaday, and in our time we’ve brought you some pretty amazing builds. But perhaps now we’ve seen the ultimate of the genre, a cyberdeck so perfect in its execution that this will be the machine of choice in the dystopian future, leaving all the others as mere contenders. It comes […]
Humans have long admired the sound of birdsong, but to fully appreciate how technically amazing it is, you need an ultrasonic microphone. [Benn Jordan] recently created a video about using these microphones to analyze a collection of bird calls, even training a starling to repeat an image encoded in sound, and has some recommendations for […]
From the outside, iron meteorites tend to look like formless, rusted lumps of metal, which is why museums often polish and etch sections to show their interior structure. This reveals their Widmanstätten patterns, a latticework structure of parallel iron-nickel intermetallic crystals which forms over millions of years of very slow solidification. Inspired by this, [Electron […]
Our hacker [Wil Carver] has sent in his submission for the One Hertz Challenge: Precise Time Ref via 1 Pulse-Per-Second GPS Signal. This GPS Disciplined Oscillator (GPSDO) project uses a Piezo 2940210 10 MHz crystal oscillator which is both oven-controlled (OCXO) and voltage-controlled (VCXO). The GPSDO takes the precision 1 Pulse-Per-Second (PPS) GPS signal and […]
PCB business cards are a creative way to show your tech skills while getting your name out there. This take on a PCB business card, sent in by [VCC], tackles one of the big challenges with them: making them in such a way that they are cheap enough to not feel bad about handing them […]
The HP 115BR is not one of the most well-known products from Hewlett-Packard. And yet, it was remarkably important nonetheless. This hardware once synced time around the world. Now, for our 2025 One-Hertz Challenge, [curiousmarc] has taken on the job of restoring it.  The HP 115BR itself was not used alone, but in concert with […]
Do you find an odd comfort in the uncanny, regular intonations of a Numbers Station? Then check out [edent]’s numbers station project, which leverages the browser’s speech synthesis engine to deliver a ceaseless flow of (mostly) numbers, calmly-intoned in various languages. The project is an entry for the annual JavaScript Golfing Competition, in which participants […]
