We like this one because it has a real Junkyard Wars feel to it: turning a cast-off fridge compressor into a two-stroke internal combustion engine. [Makerj101] is doing this with tooling no more complicated than a hacksaw and a hand drill. And...

There are few greater follies in the world of electronics than that of an electronic engineering student who has just discovered the world of hi-fi audio. I was once that electronic engineering student and here follows a tale of one of...

There is a long history of Visual or Graphical Programming Languages, and most of them make more sense than the name of Microsoft’s Visual Basic, C#, and Visual Studio IDE. Some people don’t like to code, and for them, graphical...

Whenever we see a coil gun project on the Internet, it seems to involve a bank of huge capacitors. [miroslavus] took a different approach with his gun–he wanted his project to be built without those monster caps. It’s powered by quadcopter...

While most people who make the trek to the path of totality for the Great American Eclipse next week will fix their gazes skyward as the heavenly spectacle unfolds, we suspect many will attempt to post a duck-face selfie with...

The Raspberry Pi is the perfect candidate for Google’s AIY where you can talk to a cardboard box with some electronics in it. [BuddyCasino] took on the challenge of squeezing an Alexa Client in an ESP32 and to make things interesting,...

Blog updating will be slowed down until 1 Sept 2017 due to summer vacations. See you in September with more interesting news from the open source ecosystem. The post Summer Vacations until 1 Sept 2017 appeared first on Electronics-Lab.

Ok, this one is a bit bizarre, but in perfect keeping with the subject matter: a talking toilet ripped from the pages of the Captain Underpants children’s books. Hackaday.io user [hamblin.joe]’s county fair has a toilet decorating contest and at...

Made during PIFcamp 2017, this textile sensor detects the impact of a conductive pendulum slapping against the wristband when the wrist is twisted back and forth in a flicking action. The conductive pendulum is made from a small heavy stone...

Magnets are great stuff and everyone loves them, there are so many things you can do with them, including creating a model of the crystalline structure of solids, just as [Cody´sLab] did using a bunch of magnets inside a pair...

No, not that legendary creature - nor this … Although I admit that there’s something mythical about what I’m describing here. I’m talking about the new design for JET. My goal for oh so many years has been to create...

[WolfCat] of Wolfcatworkshop is creating a hand-animated split-flap animation. But what do you use to test your animation once it’s on the split-flaps? Well, to test it out, [WolfCat] used a drill to give it motion. DoodlersAnonymous has some pics...

The World Health Organization estimates that around 90% of the 285 million or so visually impaired people worldwide live in low-income situations with little or no access to assistive technology. For his Hackaday Prize entry, [Tiendo] has created a simple...

Let’s face it — the design of most home foundries leaves something to be desired. Most foundries are great at melting metal, but when it comes to pouring the melt, awkward handling can easily lead to horrific results. That’s why...

As ever, I am fighting a marginally winning battle against my 1991 Mazda MX-5, and this is the story of how I came to install a wideband oxygen sensor in my Japanese thoroughbred. It came about as part of my...

Our Call for Proposals for the Hackaday Superconference was scheduled to close yesterday. We are extending that deadline by one week so get your proposal for a talk or a workshop in now. We want to leave no stone unturned...

There are trends in YouTube videos among various video producers. A few weeks ago, it was all about fidget spinners until some niche tech blog ran that meme into the ground. Before that, the theme was red-hot knives cutting through...

If you were a computer enthusiast in the late 1970s and early 1980s, one of your objects of desire may well have been a Sharp MZ-80K. This was an all-in-one machine from the Japanese electronics giant, and like Commodore’s PET...

[Rinoa Super-Genius] shows us in a video how to build a crude motorized barrel boat using only a few parts, including pontoons for extra buoyancy and stabilisation. Building a barrel boat is simple. All you really need is a plastic barrel,...

Dual extrusion 3D printers are not as uncommon as they used to be, but there are still a lot of single-extruder machines. [Paul Lang] wanted to refit his printer to take two MK8 extruders, and he documented his experience with...

Close to 100 German cities got NB-IoT coverage – Ground Control to the #LPWAN shuttle: “Captain N.B. you made a good job today. Within 24 hours, you made a basic scan of the LPWAN in Germany.... My blog was started...

Like it or not speed bumps are an essential part of our road infrastructure especially in built-up places like near schools [Business Insider UK] reports non-Newtonian liquid filled speed bumps are being tested in Spain, Israel and Germany. Traditional speed bumps do...

Composting serves an important purpose in our society, reusing our food scraps and yard waste to fertilize gardens rather than fill up landfills. Knowing that most people don’t compost, [Darian Johnson] set out to create a Arduino-controlled composting system to...

The badge has become one of the defining features of a modern hacker camp, a wearable electronic device that serves as both event computer and platform for some mild software and hardware hacking. Some events have had astoundingly sophisticated badges...

[Peter Sripol] is something of a legend in the DIY RC aircraft crowd. He’s friends with Flite Test, and there he built an enormous RC cargo plane that could easily carry a small child aloft. Now, [Peter] is aiming a...
