Capacitive touch sensors are entirely in the domain of DIY, requiring little more than a carefully-chosen conductive surface and a microcontroller. This led [John Phillips] to ask why not embed suc…

While we cannot be certain this is the world’s smallest digital photo frame, [Raphaël Boichot]’s Pico Slide Show is probably in the running. Since the 0.85″ TFT display would be w…

We’ve seen aircraft based on “helicopter” seeds (technically samara seeds, which include those of maples and elms) before, but this recent design from researchers at the Singapore…

Over on his YouTube channel [Ryan Inis] has a video about how electrostatic motors are breaking all the rules. He explains that these days most motors are electromagnetic but suggests that may be c…

At this point the question is no longer whether a new device runs DOOM, but rather how well. In the case of Anker’s Prime Charging Station it turns out that it’s actually not too terrib…

Computed Axial Lithography (CAL) is a lighting-fast form of volumetric 3D printing that holds incredible promise for the future, and [The Action Lab] filmed it in action at a Berkeley team’s …

Given all the incredible technology developed or improved during the Apollo program, it’s impossible to pick out just one piece of hardware that made humanity’s first crewed landing on …

Back in the day, an FM bug was a handy way to make someone’s annoying radio go away, particularly if it could be induced to feedback. But these days you’re far more likely to hear someb…

As much as I love Linux, there are always one or two apps that I simply have to run under Windows for whatever reason. Sure, you can use wine, Crossover Office, or run Windows in a virtual machine,…

To connect the miniature world of integrated circuits like a CPU with the outside world, a number of physical connections have to be made. Although this may seem straightforward, these I/O pads for…

In a recent video our hacker [Electronic Wizard] introduces the 74HC595 shift register and explains how to use it to drive 7-segment displays. [Electronic Wizard] explains that understanding how to…

A multitool that weighs less than a penny? Yes, it exists. This video by [ToolTechGeek] shows his titanium flat-cut design tipping the scales at only 1.9 grams—lighter than the 2.5-gram copper penn…

Posts on Hackaday sometimes trend a little bit retro, but rarely do we cover hacks that reach back into the Bronze Age. Still, when musician [Peter Pringle] put out a video detailing how he replica…

Now that Commodore has arisen from the depths of obscurity like Cthulhu awoken from R’lyeh, the question on every shoggoth’s squamose lips is this: “Will there be a new Commodore …

If you are casually listening to the radio, you probably tune into a local station and with modern receivers and FM modulation, the sound quality is good. But if you are trying to listen to distant…

3D printing has transformed how hobbyists fabricate things, but what additional doors would open if we could go even smaller? The µRepRap (RepRapMicron) project aims to bring fabrication at the mic…

You may have noticed the Anime Catgirls when trying to get to the Linux Kernel’s mailing list, or one of any number of other sites associated with Open Source projects. [Tavis Ormandy] had th…

Famously, Nikola Tesla won the War of the Currents in the early days of electrification because his AC system could use transformers to minimize losses for long distance circuits. That was well bef…

In this episode of the Hackaday Podcast, editors Elliot Williams and Tom Nardi start out with a warning about potentially radioactive shrimp entering the American food supply via Walmart, and thing…

A couple of decades ago now, several things happened which gave life to our world and made it what it has become. Hackerspaces proliferated, giving what was previously dispersed a physical focus. A…

Over time, web browsers have accumulated a ton of features beyond what anyone from the 90s might have imagined, from an application platform to file management and even to hardware access. While th…
