Back in the day where the microprocessor was our standard building block, we tended to concentrate on computation and processing of data and not so much on I/O. Simply put there were a lot of thing…

Students of the Samara State Aerospace University are having trouble getting a signal from their satellite, SamSat-218D. They are now reaching out to the radio amateur community, inviting everybody wi...

You can find flex PCBs in just about every single piece of consumer electronics. These traces of copper laminated in sheets of Kapton are everywhere, and designing these cables, let alone manufactu…

It seems these days all the electronics projects are wireless in some form. Whether you choose WiFi, Bluetooth Classic, Bluetooth Low Energy, ZigBee, Z-Wave, Thread, NFC, RFID, Cell, IR, or even se…

Before you zip to the comments to scream “not a hack,” watch a few minutes of this teardown video. This 48 minute detailed walkthrough of a one-off art piece shows every aspect of the p…

Wafer level chips are cheap and very tiny, but as [Kevin Darrah] shows, vulnerable to bright light without the protective plastic casings standard on other chip packages.

We covered a similar phe...

Two University of Washington students exercised their creativity in a maker space and created a pair of gloves that won them a $10,000 prize. Obviously, they weren't just ordinary gloves. These gloves...

Let's talk about tilt sensors for a second. The simplest tilt sensors - the dead simplest - are a few ball bearings rolling around in a small metal can. When the can is tilted, the balls roll into a p...

[Richard Hawthorn] sent us in this interesting fail, complete with an attempted (and yet failed) clever solution. We love learning through other people’s mistakes, so we’re passing it o…

Hollywood would have you believe that tornadoes are prevalent in the Midwest. We're much more likely to see hail in the springtime—balls of slushy ice that pelt our roofs and dimple our cars. [D...

I’ve taken lots of reference photos for various projects. The first time, I remember suffering a lot and having to redo a model a few times before I got a picture that worked. Just like measu…

[Mr. Volt] mentions that some of the commenters on his videos believed that he shouldn’t be making large, retro computer themed communicator watches. He believes they are wrong, naturally we …

Funny stuff, electricity. It’s all about the volts and the amps, and controlling these two factors. Most of the time, the electricity coming into your device is at a higher voltage than you need, so...

It’s pretty awesome to have a hardware design hero jump at the chance to work on a Hackaday conference badge. I am of course talking about Voja Antonic. I’ve gotten to know him over the…

20 students of the Eindhoven University of Technology (TU/e) in the Netherlands share one vision of the future: the fully domesticated drone pet - a flying friend that helps you whenever you need it a...

If you could spend a couple of bucks on a simple project that might prevent a $2000 repair bill on your vehicle, you'd probably build it, right? That's the idea behind this simple low-pressure alarm f...

A good first step in a project is knowing what you want to do. [Ben Fino] made it clear that his Raspberry Pi Sprinkler control system for his wife’s garden had one goal: keep the plants aliv…

Experimenting with optics can be great fun and educational. Trouble is, a lot of optical components are expensive. And other support paraphernalia such as optical benches, breadboards, and rails add t...

Software defined radios (SDRs) can–in theory–do almost anything you need a radio to do. Voice? Data? Frequency hopping? Trunking? No problem, you just write the correct software, and yo…

The AlphaGo computer has been in the news recently for beating the top Go player in the world in four out of five games. This evolution in computing is a giant leap from the 90s when computers were s...
