The magic glowing orb that tells the future has been a popular thing to make ever since we realized we had the technology to bring it out of the fortune teller's tent. We really like [jarek319]'s inte...

You can classify infrared light into three broad ranges: short wave, medium wave, and long wave. Traditionally, sensors concentrate on one or two bands, and each band has its own purpose. Short wave I...

Your home is your castle, and you are king or queen of all you survey. You’ve built your own home-automation system from scratch. Why would you possibly settle for the stock firmware in your …

Did you know the muzzle velocity of a NERF dart out of a toy gun? Neither did [MJHanagan] until he did all sorts of measurement. And now we all know: between 35 and 40 miles per hour (around 60 km/h)....

The incredible screw drive tractor is back. We've covered the previous test ride, which ended with a bearing pillow block ripping in half, but since then, again, a lot of repair work has been done. ...

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...
