Hacking on Raspberry Pi board internals is one of my favourite topics. I know a bunch of obscure things about these cute little boards. Three years ago, I covered a Raspberry Pi 4 RAM upgrade ...

Much of science is performed through inference, with the readings on instruments, a flash of light in heavy water, or the ...

Of the popular 1980s 8-bit computers, it’s fair to say that Sinclair’s ZX Spectrum punched above its weight. Sir Clive’s love ...

As cool as it would have been to wield lasers that produce a beam of neutrinos, recently two papers were published by MIT researchers that seem to dampen the likelihood of such lasers being at all ...

Large format cameras can produce amazing shots, but are a bit too bulky to be practical. Medium format is a different story, as [Wenting] demonstrates with his Sitina B220M — an open-source ...

Coaxing a DVI signal out of a microcontroller to drive a DVI or HDMI screen has been possible for a while now, but limitations in what the devices can do has, in turn, placed a limit on the ...

We depend on the Hackaday community to help us find all the fresh hacks the Internet has to offer. Whenever you see something you think should be discussed on Hackaday we want to hear from you. This ...

[Adafruit]’s Voicebox FX gadget is a fun, well-documented project that serves another useful purpose: being a fantastic reference design for audio on CircuitPython, with I 2 S audio components. Be ...

There’s a slew of hardware hacker problems that a logic analyzer is in a perfect position to solve. Whether you’re trying to understand why an SPI LCD screen doesn’t initialize, what’s up with your ...

For decades now, companies like Michelin have been teasing us with futuristic-looking automobile tires that don’t use air. Instead, they use a polymer mesh of sorts which maintains the same pressure ...

Cycloidal gearboxes are a recurring theme in the hobbyist space due to the performance they promise in a compact package. They are capable of taking in a high-speed input and reducing it down to a set ...

When it comes to building real-world flying vehicles, testing can be arduous and expensive. You have to find somewhere to fly, then you have to contend with environmental conditions and the ...
