A few years ago, FLIR unleashed a new line of handheld thermal imagers upon the world. In a manufacturing triumph, the cheapest of these thermal imaging cameras contained the same circuitry as the …

Most of us who have dabbled a little in electronics will have made our own printed circuit boards at some point. We'll have rubbed on sticky transfers, laser-printed onto acetate, covered our clothing...

The history of aviation is a fascinating one, spanning more than two thousand years starting from kites and tower jumping. Many hackers are also aviation fans, and the name of Alberto Santos Dumont…

When our new computer overlord arrives it'll likely give orders using an electromagnetic speaker (or more likely, by texting instead of talking). But for a merely artificial human being, shouldn't we ...

This Friday, February 10th, at 9am PST, Hackaday.io will be graced with one of the greatest hardware creators in recent memory. [Bunnie Huang] will be talking about making and breaking hardware in the...

If you’re reading these pages, odds are good that you’ve worked with I²C devices before. You might even be the proud owner of a couple dozen sensors pre-loaded on breakout boards, ready…

Hackaday's Sci-Fi Contest is in its third week. We've passed warp speed and were heading toward ludicrous speed. There is still almost a month to enter before March 6, when the deadline hits and every...

[Kevinhub] noticed there were quite a few FPGA hats for the Raspberry Pi. Instead going out and buying one of these boards like a filthy commoner, he decided to spin up his own FPGA Pi accessory. T…

Remember that feeling when you first looked down on a microscope? Now you can re-live it but in slightly different way. [Venkes] came up with a way to make a Laser Scanning Microscope (LSM) with mo…

If you lay out PC boards using software, it is a good bet you have an opinion about autorouters. Some people won't use a package that can't automatically route traces. Others won't accept a machine la...

We see a lot of Raspberry Pi projects on these pages featuring all variants of the little board from Cambridge, but with one notable exception. Surprisingly few of them have featured its industrial…

Problem: you're a student mechanic and you've already poured a ton of money into a Snap-On roller cabinet loaded with the tools of the trade, but you still need sensible storage for your cordless tool...

How many of you speak more than one language? Since Hackaday is an English-language site whose readership is world-wide, we are guessing quite a lot of you are not monoglots. Did you learn your secon...

Over the last decade or so the definition of what a ‘small satellite’ is has ballooned beyond the original cubesat design specification to satellites of 50 or 100 kg. Today a ‘smallsat’ is def...

Watch aficionados have a certain lust for mechanical watches. These old school designs rely on a spring that’s wound up to store energy. The movement, an intricate set of gears and other mech…

I had a friend who was an electronics assembly tech for a big defense contractor. He was a production floor guy who had a chip on his shoulder for the engineers with their fancy book-learnin’…

XKCD 936, the comic that introduced the phrase, 'correct horse battery staple' into both the lexicon and password dictionaries, is the best way to generate a password. Your passwords should be random ...

Sometimes a project comes our way which has so much information contained in it as to be overwhelming, and on which it is difficult to know where to start. A good example is [Barry Armstead]’…

High-altitude balloons are used to perform experiments in “near space” at 60,000-120,000 ft. (18000-36000m). However, conditions at such altitude are not particularly friendly and balloons have to...

When teaching Industrial Automation to students, you need to give them access to the things they will encounter in industry. Most subjects can be taught using computer programs or simulators &#8212…
