Have you ever wished that a laser could tell you the weather? If you have, then [tuckershannon] has you covered. He’s created a machine that uses a laser and some UV sensitive paper to draw t…

When we lose a limb, the brain is really none the wiser. It continues to send signals out, but since they no longer have a destination, the person is stuck with one-way communication and a phantom-…

If you were to make a list of the most important technological achievements of the last 100 years, advanced medical imaging would probably have to rank right up near the top. The ability to see ins…

The greatest challenge of robotics is autonomy. Usually, this means cars that can drive themselves, a robotic vacuum that won’t drive down the stairs, or a rover on Mars that can drive on Mar…

Some projects end up being more objet d’art than objet d’utile, and we’re fine with that — hacks can be beautiful too. Some hacks manage both, though, like this study in sil…

If you are interested in deploying LoRa — the low power long-range wireless technology — you might enjoy [Rui Santos’] project and video about using the ESP32 with the Arduino IDE…

What do you do if you’re laying out a PCB, and you need to jump over a trace, but don’t want to use a via? The usual trick is using a zero Ohm resistor to make a bridge over a PCB trace…

If you’re anything like us, more than a few of your projects were borne out of the fact that you had some crusty bit of gear that was badly in need of a second lease on life. Whether it was a…

Would you play a game of Pong where each set lasts exactly one minute and the right player is guaranteed to win 60 times more than the left player? Of course not, but if you were designing a clock …

Nvidia is back at it again with another awesome demo of applied machine learning: artificially transforming standard video into slow motion – they’re so good at showing off what AI can …

There is joy in the hearts of British and European hardware and software hackers and makers, for this is an EMF Camp year. Every couple of years, our community comes together for three summer days …

Today, SiFive has released two new cores designed for the lower end of computing. This adds to the company’s existing portfolio of microcontrollers and SoCs based on the Open RISC-V ISA. Over…

When it has become so common for movies and television to hyper-sensationalize engineering, and to just plain get things wrong, here’s a breathe of fresh air. There’s a Sci-Fi show out …

How do you feel about Jello? It’s alright tasting, but it’s much more about how jiggly it gets. Nobody — probably — would eat Jello if it was a hard candy. It would quickly …

With more and more embedded systems being connected, sending state information from one machine to another has become more common. However, sending large packets of data around on the network can b…

A big part of the Hackaday Prize this year is robotics modules, and already we’ve seen a lot of projects adding intelligence to motors. Whether that’s current sensing, RPM feedback, PID…

Consider the piggy bank. Behind that innocent, docile expression is a capitalistic metaphor waiting to ruin your fond memories of saving for that BMX bike or whatever else it was that drove home th…

Makerbot 3D printers were among the first to hit the market, so it makes sense that old and broken ones now litter the shelves of hackerspaces and home workshops alike. Rather than throw his one ou…

The GOES-R series of Earth observation satellites are the latest and greatest NASA has to offer. As you might expect, part of the GOES-R job description is imaging Earth at high-resolution, but the…

In Northern England, the hills used to be home to steam trains. The trains have long faded into history, but the sound of their whistle is making a brief return. Artist [Steve Messam] has created &…
