Sometimes when browsing the websites of our global hackspace community you notice a project that's attractive not necessarily because of what it does or its technology but because of its presentation....

Pushing the maker envelope all the way to the Master level, [Przemyslaw Brudny], [Marek Ulita], and [Maciej Olejnik] from the Politechnika Wroclawska in Poland packed a UAV full of custom sensor board...

Just in case you imagine that those of us who write for Hackaday are among the elite of engineering talent who never put a foot wrong and whose benches see a succession of perfectly executed builds an...

[Neumi] wrote in with a sweet robotics hack. It’s a 2D laser distance sensor (YouTube) made with a cheap line laser and an optical mouse’s flow-sensor chip used as a low-resolution came…

If you’re a long-time Hackaday reader like we are, you’ll certainly remember a rash of projects from around ten years ago that all (mis-)used an LED as a light sensor. The idea wasn&#82…

There's a gritty feel to the Hackerboat project. It doesn't have slick and polished marketing, people lined up with bags of money to get in on the ground floor, or a flashy name (which I'll get to in...

A corollary to Godwin’s Law ought to be that any Hackaday post that mentions Nikola Tesla will have a long and colorful comment thread. We hope this one does too, but with any luck it’l…

[Mark Gibson] probably has nothing against silicon. He just knows that a lot that can be done with simple switches, relays, and solenoids and wants to share that knowledge with the world. This was ma...

If you have ever wondered what it took to make your own custom graphic LCD from scratch, this video from [Applied Science] is worth a watch. It’s concise and to the point, while still telling…

In 1820, Hans Christian Oersted discovered the needle of a compass would deflect when placed next to a wire carrying an electric current. It took 15 years for the first electric motor to be invente…

Most DJ tools are just ripe for DIY rework. Everything at least speaks MIDI, and the firmware side of the equation that makes a physical interface for your laptop can be downloaded and flashed with mi...

One of the first electronics projects for the aspiring hobbyist is wiring a sensor of some sort to a microcontroller, and then doing something useful with the new information. [Brock] has taken thi…

The idea of winding inductive guitar pickups by hand is almost unthinkable. It uses extremely thin wire and is a repetitive, laborious process that nevertheless requires a certain amount of precisi…

[Paweł Spychalski] wrote in to tell us about some experiments he’s been doing, using cheap 433 MHz HC-12 radio units as a telemetry radio for his quadcopter. In this blog post, he goes over t…

Skateboarding is a sport that was born of hacking. The identity of the person who first nailed roller skate wheels to a board with a milk crate box is lost to history. Those crate scooters were a stap...

Here's a neat hack for making a magnetic charging mount for a cell phone. We know what you're thinking, but this is definitely not a traditional contactless charging system. Those use magnets but in ...

3D printing seems like it takes forever when you’re waiting for a part to come out. But if you’re like us, the real time spent in making something new is in modelling and refining the p…

If we had a dime for every 555-based noisemaker circuit we see… But this one’s got a twist. [Tristan] does two things that elevate his sawtooth-wave noisemaker above the norm. First, he…

Confocal microscopy is an imaging technique that provides higher resolution micrographs than that of traditional optical microscopy. Confocal microscopes attain this higher resolution from an image se...

We have no intention of wading into the vacuum tube versus silicon debates audiophiles seem to thrive on. But we know a quality build when we see it, and this gorgeous tube preamp certainly looks l…
