It's been about a year and a half since the Batteroo, formally known as Batteriser, was announced as a crowdfunding project. The premise is a small sleeve that goes around AA and AAA batteries, boosti...

Soon, the ball will drop in Times Square, someone will realize you can turn '2018' into a pair of novelty sunglasses, and the forgotten mumbled lyrics of Auld Lang Syne will echo through New Year's ...

For anyone living in cooler climates, the annual onslaught of snow means many hours shoveling driveways and sidewalks. After a light snow, shoveling might seem a waste of time, while a snow blower …

We’re used to reflow soldering of our PCBs at the hacker level, for quite a few years people have been reflowing with toaster ovens, skillets, and similar pieces of domestic equipment and equ…

Hey, that's me! I had the honor of giving a talk at the Hackaday SuperConference in November about our editorial direction over the past year and looking towards the next. At any given time we have ab...

If you aren’t old enough to remember programming FORTRAN on punched cards, you might be surprised that while a standard card had 80 characters, FORTRAN programs only used 72 characters per ca…

The Chaos Communication Congress (CCC) is the largest German hacker convention by a wide margin, and it’s now in its thirty-third year, hence 33C3. The Congress is a techno-utopian-anarchist-…

A well-designed phone case will protect your phone from everyday bumps with only as much style flair as you’d like. While protection is usually the only real function of a case, some designs …

We'll admit it: we sometimes overcomplicate things. Look at [Peter Weissbrod's] automated cat feeder, for example. It isn't anything more than a bottle, a servo, some odds and ends, and an Arduino. Ho...

How much game can you get out of a chip with only 1 kB of flash memory and (five or) six free GPIOs? Well, you can get it to play the classic memory game, Simon. [Vojtak] is submitting this project…

[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 …
