This article will help you build a simple Arduino-based DCC system. Growing up in the 1980s I was living the dream. I had an HO layout on a 4 x 8 sheet of plywood in my parents' basement in Reading, ...

A little over a year ago we’d written about a sub $100 muon detector that MIT doctoral candidate [Spencer Axani] and a few others had put together. At the time there was little more than a paper on ...

Nanoplastics—plastic particles smaller than one micrometer—are generated through the degradation and abrasion of plastic products and are increasingly detected in food, drinking water, air and ...

You've likely had a printer that didn't work and needed to be replaced or disposed of. However, it's not a big pile of plastic and metal heading straight for a dump. If you are a resourceful maker, an ...

The ESP32-C3 has gained eyes. A project has emerged that connects to a TCS34725 RGB color sensor to identify colors in real time. This project is more than just color detection. It is the first step ...

Every summer, algal blooms turn rivers and lakes green. Although they are widely known as a major form of water pollution ...

Pangram, an A.I. detection start-up, promises near-perfect accuracy in sniffing out writing and imagery that wasn’t made by ...

Researchers have created a wearable patch that can detect hazards in the environment—such as dangerous gases or heavy metals ...

The scale of AI-generated media can be hard to grasp. Starling Lab, a research collaboration from Stanford University and the ...

Building a 3D motor printed motor is one thing, but creating a completely custom servo motor with encoder requires some significant engineering. In the video after the break [365 Robots] takes us ...

They tested the method by injecting microplastics from ground-up pen lids into mice. This image was taken 1 h after injection ...
