If all you want is just a basic WiFi extender that gets some level of network connectivity to remote parts of your domicile, then it might be tempting to get some of those $5, 300 Mbit extenders off Temu as [Low Level] recently did for a security audit. Naturally, as he shows in the subsequent […]
One of the ongoing rumors and scandals in professional cycle sport concerns “motor doping” — the practice of concealing an electric motor in a bicycle to provide the rider with an unfair advantage. It’s investigated in a video from [Global Cycling Network], in which they talk about the background and then prove its possible by […]
Nobody likes power cords, and batteries always need recharging or replacing. What if your device could run on only the power it could gather together by itself from the world around it? It would be almost like free energy, although without breaking the laws of physics. Hackaday’s 2026 Green-Powered Challenge asks you to show us […]
Before it became viable to distribute and play music tracks on home computers, the use of FM and Wavetable synthesis was very common, with MIDI Wavetable-based devices like the Roland MT-32 and SC-55 still highly sought after today. The Creative Midi Blaster MB-10 that [Yeo Kheng Meng] reviewed and tore down for an analysis isn’t […]
A lot of making goes on in this community these days, but sometimes you’ve just gotta do some old fashioned hacking. You might have grabbed an old Speak and Spell that you want to repurpose as an interface for a horrifyingly rude chatbot, or you’ve got a calculator that is going to become the passcode keypad […]
A hackerspace is a place that generally needs to be accessed by a wide group of people, often at weird and unusual hours. Handing around keys and making sure everything is properly locked up can be messy, too. To make it easy for hackers to get in to [Peter]’s local hackerspace, a simple electronic system […]
The construction of a large language model (LLM) depends on many things: banks of GPUs, vast reams of training data, massive amounts of power, and matrix manipulation libraries like Numpy. For models with lower requirements though, it’s possible to do away with all of that, including the software dependencies. As someone who’d already built a […]
If you want to pull apart a program to see how it ticks, you’re going to need a disassembler. [Ricardo Quesada] has built Regenerator 2000 for just that purpose. It’s a new interactive disassembler for the Commodore 64 platform. Naturally, Regenerator 2000 is built with full support for the 6502 instruction set, including undocumented op-codes […]
Unlike on Earth there aren’t dozens of satellites whizzing around Mars to provide satellite navigation functionality. Recently NASA’s JPL engineers tried something with the Perseverance Mars rover that can give such Marsbound vehicles the equivalent of launching GPS satellites into Mars orbit, by introducing Mars Global Localization. Although its remote operators back on Earth have […]
Historically, moving and pointing a camera while filming was the job of a highly-skilled individual. However, there are machines that can do that, enabling all kinds of fancy movement that is difficult or impossible for a human to recreate. A great example is this pan-tilt build from [immofoto3d.] The build uses a hefty cradle to […]
