First things first: the tease on this video, that an electric supercar can be charged from a massive lemon battery array, is exactly that – a tease. Despite that, it makes for an interesting …

Got $4,000 to spend? Even if you don’t, keep reading — especially if you develop with FPGAs. Exostiv’s FPGA debugging setup costs around $4K although if you are in need of debuggi…

In the early 1980s there was growing public awareness that the microcomputer revolution would have a significant effect on everybody’s lives, and there was a brief period in which anything re…

Clock movements are beautifully complex things. Made up of gears and springs, they’re designed to tick away and keep accurate time. Unfortunately, due to the vagaries of the universe, various…

Sonar measures distance by emitting a sound and clocking how long it takes the sound to travel. This works in any medium capable of transmitting sound such as water, air, or in the case of FingerPi…

Robotic arms – they’re useful, a key part of our modern manufacturing economy, and can also be charming under the right circumstances. But above all, they are prized for being able to u…

Today’s CPUs are so advanced that they might as well be indistinguishable from magic, right? Wrong! Fundamentally, modern CPUs can be understood logically like any other technology, it’…

Most posts here are electrical or mechanical, with a few scattered hacks from other fields. Those who also keep up with advances in biomedical research may have noticed certain areas are starting t…

When [Felix Rusu], maker of the popular Moteino boards which started life as wireless Arduino compatibles, says he’s made a wireless ring light for his SMD microscope, we redirect our keystro…

There’s an old saying that the cobbler’s children have no shoes. Sometimes we feel that way because we stay busy designing things for other people or for demos that we don’t have …

If you haven’t been following the Nintendo Switch hacking scene, the short version of the story is that a vulnerability was discovered that allows executing code on all versions of the Switch…

The Raspberry Pi in general (and the Zero W model in particular) are wonderful pieces of hardware, but they’re not entirely plug-and-play when it comes to embedded applications. The user is o…

Remember when computer mice didn’t have scroll wheels? The greatest mouse of all time, the Microsoft Intellimouse Explorer 3.0, is back in production. This mouse was released in 2003, before …

Fans of technology will recall a number of years when Honda’s humanoid robot Asimo seemed to be everywhere. In addition to its day job in a research lab, Asimo had a public relations side gig…

Beds! They don’t move around enough, so the young people say. They need more motors, more horsepower, more self-driving smarts – right? Honestly, we’re not sure, but if that&#8217…

We like it when hacks are literal hack jobs, put together with what’s on hand to do a specific job. This quick and dirty angle grinder circle cutter certainly fills the bill, and makes decent…

We have a friend who has always been obsessed that he didn’t invent the Weed Eater. After all, it is just some fishing line and a motor. We might feel the same way about Easy-Peelzy, which [M…

Octoprint is a household name for anyone into 3D printing and anyone regularly reading Hackaday. Described by creator Gina Häußge as “the snappy web interface for your 3D printer”, Octo…
