Maybe its a capture file from a network dump. Maybe it’s from an Arduino. Maybe it is a random file off the Internet. But there will be a time when you have a file full of seemingly meaningle…

[Bill]  purchased a house in Central Florida, and like any good hacker, he started renovating, pulling Ethernet cables, and automating things. Lucky for us, he decided to write up his experiences a…

Steganography involves hiding data in something else — for example, encoding data in a picture. [David Buchanan] used polyglot files not to hide data, but to send a large amount of data in a …

One of the best things about working at the Linux (or similar OS) command line is the use of pipes. In simple terms, a pipe takes the output of one command and sends it to the input of another comm…

There was an endless supply of fantastic projects at Supercon this year, but one whose fit and finish really stood out was [Scott]’s lightsaber. If you were walking around and saw someone wit…

You’ve no doubt been exposed to the ads for various inventor services; you have an idea, and they want to help you commercialize it and get the money you deserve. Whether it’s helping y…

Amazon might not be happy about it, but at least part of the success of their Fire TV Stick was due to the large hacking and modification scene that cropped up around the Android-powered device. A …

The cost of tools and test equipment has largely been on the downward trend for years, making it now more affordable than ever to get into the hacking and making scene. This is particularly visible…

Is it ironic when a YouTube channel named “The Current Source” needs to build a current source? Or is that not ironic and actually just coincidental? Regardless of linguistic considerat…

For Hackaday readers who spend more time with a soldering iron than a saw, a marking gauge is a tool used to put parallel lines on a piece of wood (and occasionally metal or plastic) for cutting. T…

If you are used to coding with almost any modern tool except the Arduino IDE, you are probably accustomed to having on-chip debugging. Sometimes having that visibility inside the code makes all the…

For hackers, cheap (and arguably disposable) consumer hardware makes for a ready supply of free or low-cost components. When you can walk into a big box store and pick up a new low-end laptop for $…

For most of human history, our inventions and innovations have been at a scale that’s literally easy to grasp. From the largest cathedral to the finest pocket watch, everything that went into…

For Hackaday readers which might not be so well versed in the world of home video gaming before the 1983 crash, the Vectrex was an interesting attempt at bringing vector graphics into player’…

A weekend for people who love hardware, by people who love hardware. It’s a simple recipe and it makes a delicious event that we call the Hackaday Superconference. If you made it to Pasadena …

What’s the best way to turn a high-powered brushless DC motor optimized for hobby use into a decent low-RPM generator? Do you take a purely mechanical approach and slap a gearbox on the shaft…

Perhaps you heard about Oumuamua (don’t ask us how to pronounce that). The cigar-shaped object is the first item found by astronomers that is known to have come from outside the solar system …

There are few limits to the extent audiophiles will go in their quest for the perfect sound. This applies in particular to the loudspeaker, and with that aim [Heine Nielsen] has created an eye-catc…

We play host to a lot of incredibly complex projects here at Hackaday; take a look at some of the entries in the Hackaday Prize for some real world-class engineering. But the hacks you can knock ou…

It used to be a spectrum analyzer was an exotic piece of gear. However, these days it is pretty common for a scope to have some ability to do the job — that is, plot amplitude versus frequenc…
