[ad_1] One of the things you’re paying for when you buy a 3D printer from Prusa Research is, essentially, your next 3D printer. That’s because Prusa’s machines are designed to be upgraded and modified as time goes on. An upgrade kit is always released to allow each older printer to be converted into its successor, […]

[ad_1] There are a ton of fun Raspberry Pi and Linux projects that require audio output – music players, talking robots, game consoles and arcades, intelligent assistants, mesh network walkie-talkies, and much more! There’s no shortage of Pi-based iPods out there, and my humble opinion is that we still could use more of them. To […]

[ad_1] How hard is it to make a fully standalone SDR? [101 Things] shows you how to take a breadboard, a PI Pico, and two unremarkable chips to create a capable radio. You can see the whole thing in the video below. The design uses a standard Tayloe demodulator. There’s also an encoder and an […]

[ad_1] What can you do with a one-button keyboard? Quite a bit, actually, especially if that key has a little screen on it. That’s the idea behind [Maker M0]’s MagicClick macro pad, which is an updated version of a highly useful project we have featured in the past. Well, now there’s a tiny game to […]

[ad_1] The decline of AM broadcast radio is a slow but inexorable process over much of the world, but for regions outside America there’s another parallel story happening a few hundred kilohertz further down the spectrum. The long wave band sits around the 200kHz mark and has traditionally carried national-level programming due to its increased […]

[ad_1] “Please say it wasn’t a regex, please say it wasn’t a regex; aww, crap, it was a regex!” That seems to be the conclusion now that Crowdstrike has released a full root-cause analysis of its now-infamous Windows outage that took down 8 million machines with knock-on effects that reverberated through everything from healthcare to […]

[ad_1] [Ryan Miceli] had spent a few years poring over and reverse-engineering Halo 2 when a friend asked for a favor. His friend created an improved Xbox with significant overclocks, RAM upgrades, BIOS hacks, and a processor swap. The goal was simple: patch the hardcoded maximum resolution from 480p to 720p and maybe even 1080p. […]

[ad_1] There’s something inspiring about echos. Who among us hasn’t called out or clapped hands in a large space just to hear the sound reflected back? Radio takes this to a whole new level. You can bounce signals from buildings, aircraft, the ionisphere, or even the Moon itself. Humans have been bouncing radio waves from […]

[ad_1] There are many forms of human interface device beyond the ubiquitous keyboard and mouse, but when it comes to fine-tuning a linear setting such as a volume control there’s nothing quite like a knob. When it comes to peripherals it’s not the size that matters, as proven by  [Stefan Wagner] with the Tiny Knob. […]

[ad_1] A team at Google has spent a lot of time recently playing table tennis, purportedly only for science. Their goal was to see whether they could construct a robot which would not only play table tennis, but even keep up with practiced human players. In the paper available on ArXiv, they detail what it […]
