[GreatScott!] needs to light off fireworks with an arc rather than a flame, because “fireworks and plasma” is cooler than fireworks and no plasma. To that end, he attempted to reverse e…

[Ken Shirriff] is no stranger to Hackaday. His latest blog post is just the kind of thing we expect from him: a tear down of the venerable 8008 CPU. We suspect [Ken’s] earlier post on early C…

We get a lot of press releases at Hackaday, but this one was horrific enough that we thought it was worth sharing. Apparently, some kids are accidentally eating lithium coin cell batteries. When this ...

Emulation is a difficult thing to do, particularly when you're trying to emulate a complex platform like a game console, with little to no public documentation available. Often, you'll have to figure...

Many of us will have seen robotics or prosthetics operated by the electrical impulses detected from a person’s nerves, or their brain. In one form or another they are a staple of both mass-ma…

Industrial hardware needs to be reliable, tough, and interoperable. For this reason, there are a series of standards used for command & control connections between equipment. One of the more wid...

Sometimes the hack is a masterwork of circuit design, crafting, 3D printing and programming. Other times, the hack is knowing which tool is right for the job, even when the job isn’t your reg…

Numbers stations are shortwave stations that broadcast cryptic messages that are widely assumed to be used for communications between nation states and spies. But who’s to say it’s up t…

When going about a busy day, a hard copy listing all your tasks helps if you aren't inclined to pull up a notepad -- or whatever app you use -- on your phone each time; doubly so if you want to pin it...

Preserving old arcade games is a niche pastime that can involve some pretty serious hacking skills. If the story here were just that someone pulled the chip from a game, took it apart, and figured …

The smart thermostat has become in a way the public face of the Internet of Things. It’s a demonstration that technological uptake by the general public is driven not by how clever the techno…

IKEA sometimes seems like a DIY store disguised as a furniture store. We may go there looking for a new sofa or kitchen table, but, to the DIY enthusiast, it’s a shop full of possibilities. W…

Trimming one’s Christmas tree can be an enjoyable tradition year after year, but every once in a while some variation on  the established order can be just as fun. Seeking some new ornaments …

Circuit bending is the art of creatively short circuiting low voltage hardware to create interesting and unexpected results. It’s generally applied to things like Furbys, old Casio keyboards,…

You screwed everything up last night. The end of 2016 had a leap second, so instead of the seconds going up from 57, 58, 59… 00, there was a 61st second in the last minute of the year. Yeah, …

If you take an object and turn it into something else, does that constitute a hack?  Can a musical robot call to question the ethics of firearms exports? If you take a disabled shotgun and turn it in...

[Aldric Negrier] is no stranger to the 3D printing world. Having built a few already, he designed and built an SLA/DLP 3D printer, named RooBee One, sharing the plans on Instructables. He also publ…

A frequent early project for someone learning to use a microcontroller such as an Arduino board involves hooking up a temperature sensor and an LCD display to make a digital thermometer. Not many com...

Sure, you’d like to get in on all the retrocomputing action you read about on Hackaday. But that takes a lot of money to buy vintage hardware, right? Sure, you can build your own, but who has…

There was a time when electronic hackers (or hobbyist, enthusiasts, geeks, or whatever you want to be called) were better than average at geography. Probably because most of us listened to shortwav…
