Continuity testing is one of the most valuable functions on the modern multimeter. It will help you investigate wiring problems in your car, tell you if you’re holding a nullmodem serial cable or the regular kind, and even reveal when you’ve accidentally shorted the data lines right to the power supply. However, all that beeping […]
Hackaday and Seeed Studio are hosting a meetup in Shenzhen on Friday, March 22nd and you are invited! This meetup is happening at X.factory, a maker hub run by Seeed Studios. Sophi Kravitz and Mike Szczys will be in town for the meetup and will both speak, along with a project talks from members of […]
Some of the best educational material we’ve seen tells a story. There’s something more fun about reading a story than just absorbing a bunch of dry facts. That’s the idea behind Adventures in Logic Land. In the first episode, you are abducted by aliens trying to decide if humans are intelligent. To prove that, you […]
The lack of HDMI inputs on almost all laptops is a huge drawback for anyone who wants to easily play a video game on the road, for example. As to why no manufacturers offer this piece of convenience when we all have easy access to a working screen of this size, perhaps no one can […]
We always look forward to the builds [MakerMan] sends in, and it’s not just because we dig his choices in royalty free music (though it helps). He always manages to put together his projects with a minimum of fuss, and perhaps more importantly, a minimum of funds. His builds use salvaged components, easily sourced materials, […]
[Ignacio]’s VIRK I is a robot arm of SCARA design with a very memorable wooden body, and its new gripper allows it to do a simple pick and place demo. Designing a robot arm is a daunting task, and the fundamental mechanical design is only part of the whole. Even if the basic framework for […]
I was a little surprised to see a news report about Andreas Schleicher, the director of education and skills at OECD — the Organization for Economic Cooperation and Development. Speaking at the World Innovation Summit for Education in Paris, Schleicher thinks that teaching kids to code is a waste of time. In particular, he seems […]
Drilling holes is easy; humans have been doing it in one form or another for almost 40,000 years. Drilling really tiny holes in hard materials is more challenging, but still doable. Drilling deep, straight holes in hard materials is another thing altogether. Luckily, these days we have electric discharge machining (EDM), a technique that opens […]
When the first 737 MAX entered service in May of 2017, it was considered a major milestone for Boeing. For nearly a decade, the aerospace giant had been working on a more fuel efficient iteration of the classic 737 that first took to the skies in 1967. Powered by cutting-edge CFM International LEAP engines, and […]
RISC architecture might change the world, but it runs an NES emulator right now. That’s thanks to MaixPy, the new MicroPython for the K210, the recently released RISC-V microcontroller that’s making waves in the community. [Robot Zero One] has the tutorial and [Other Dave] of EEVBlog has a video of the thing in action. The […]
