This week, we’re continuing our Creating A PCB In Everything series, where we go through the steps to create a simple, barebones PCB in different EDA suites. We’re done with Eagle, and …

When you have an MQTT broker receiving messages, you want to be able to see them. [Xose Pérez] already had a system set up that sent him notifications, but he had a pair of 32×16 LED matrices,…

[ossum] has a baby on the way. He admits that he got a bit carried away, brimming with parental excitement. What resulted is a fully articulated LED WiFi lamp that blooms and glows dramatically in …

[Tallaustin] worked at Stratasys as an intern this past summer. They let him know that he was welcome to use their fancy industrial printers as much as he'd like. Not to waste such an opportunity ...

[Tez] has acquired and resurrected a piece of New Zealand computing history, the Poly-1. To anyone who went to school in 1980s Britain, the Poly-1 appears to be a cooler, mirror universe version o...

The Hands|On glove looks like it's a PowerGlove replacement, but it's a lot more and a lot better. (Which is not to say that the Power Glove wasn't cool. It was bad.) And it has to be -- the task that...

NextThingCo, makers of the very popular C.H.I.P. single board Linux computer, have released the latest iteration of their hardware. It’s the C.H.I.P. Pro, an SBC designed to be the embedded b…

Retrocomputing is an enjoyable and educational pursuit and — of course — there are a variety of emulators that can let you use and program a slew of old computers. However, there’…

Computer handwriting recognition is very cool by itself, and it’s something that we’d like to incorporate into a project. So we went digging for hacker solutions, and along the way came…

Get together with awesome hackers and build something cool. That's the exact description for the workshops of the Hackaday SuperConference. Previously we announced all of the talks and some of the wor...

There was a time when if you wanted to scale a wall you had to turn a camera on its side and call [Adam West] or [Lionel Ritchie]. Unless you were a gecko, that is. Their host of tiny bristles and …

Every now and then you need to make your own capacitor. That includes choosing a dielectric for it, the insulating material that goes between the plates. One dielectric material that I use a lot is…

Silicon transistors keep shrinking (current state of the art is about 20 nanometers). However--in theory--once the gate goes to 5 nanometers, the electrons tunnel through the channel making it impossi...

Taking a break from his book, “How to Gain Enemies and Encourage Hostility,” [FPS Weapons] shows us how to build our own handheld EMP generator which can be used to generate immediate d…

Compressed air is great to have around the shop. The trouble is, most affordable compressors are somewhere between “wake the dead” and “the reason Pete Townshend is deaf” on…

It is not uncommon for parts from a particular hobby or pursuit to be repurposed by enthusiasts as furniture. Car nuts will make sofas from the rear bodywork of a saloon car, for example, or coffee t...

The theme of the last Hackaday Prize challenge was Assistive Technologies, and there is perhaps no assistive technology as desperately needed as a device to help people who can’t use common i…

At Hackaday, we get notified of a lot of the cool events going on in hackerspaces all around the world. We’d like to keep you informed too, just in case there’s something going on in yo…

This hacker’s video on blinking LEDs never got the recognition it deserves. At the time of writing clocking in at just 61 views, but it is indeed a work of art. Just trust me, scroll to the b…

There it was, after twenty minutes of turning the place over, looking through assorted storage boxes. A Thinwire Ethernet network. About the smallest possible Thinwire Ethernet network as it happen…
