Everyone’s a critic, but it’s hard to argue with success. And that’s exactly what [agp.cooper] has with his ATtiny85-based spectrum analyzer devices. The “normal” way …

Home-built foundries are a popular project, and with good reason. Being able to melt and cast metal is a powerful tool, even if it's "only" aluminum. But the standard fossil-fuel fired foundries that ...

Speech synthesis is nothing new, but it has gotten better lately. It is about to get even better thanks to DeepMind’s WaveNet project. The Alphabet (or is it Google?) project uses neural netw…

What’s your favorite value of resistor? 1K? 10K? They’re all fine, but when you need nearly no resistance at all, nothing beats the good old zero-ohm resistor. Wait a minute! Resistors …

Just a few weeks ago, we reported on a US NASA project to track the path and estimate the size of meteoroids in the sky using a distributed network of a handful of cameras. It turns out that there&…

We humans walk funny. Pivoting one leg forward at the hip creates an offset that puts us off-balance sideways. We have to compensate for this with each step we take. Many robots handle this by instead...

The Otto DIY robot has just taken first place in the coveted role as "best robot to 3D print for your (inner) child". It's cute, it dances, it doesn't cost too much, it's completely open source, and i...

If you’ve been in a university class of a certain size, with a professor who wants to get live feedback from the students, you’ve probably been forced to buy a Turning Point “clic…

NASA is looking for a few good men and women to solve an upcoming problem. Astronauts will soon be venturing outward beyond Earth orbit. If the spacecraft cabin should depressurize then they’…

The Chaos Communication Congress is growing! Actually, it's not, but there may be an 'overflow venue' for everyone who didn't get a ticket. There's a slack up for people who didn't get a ticket to 33...
