Watch your music come to life on this single LED strip audio spectrum visualizer

While thinking of an interesting project to create, Hackster user marcaubin started to imagine an audio spectrum visualizer, but not a traditional one that has a matrix of LEDs with columns corresponding to certain frequencies. Instead, his device would have just a single vertical NeoPixel strip featuring 29 LEDs in total, with the bottom ones displaying the […]

This may be one of the cheapest and easiest CNC drawing machines you’ll find

CNC plotters are a lot of fun to build and use, as they teach mechanics, electronics, and how G-code works. However, traditional Cartesian machines often require expensive components such as linear rods and ample amounts of bearings to move in just two axes. YouTuber DAZ Projects set out to change that by assembling a form of a […]

Researchers developed fabric-friendly NFC antennas that can be woven into furniture

Near-field communication, or NFC for short, has started popping up everywhere as a way to easily pay, unlock doors, or even start a car. And now it can do one more thing: locate and track objects within a room. Researchers at Carnegie Mellon University’s Laboratory for Emerging Wireless Technologies have come up with an ingenious method to […]

The FANTM DEVLPR is an open source electromyography Arduino shield

Human-to-computer interfaces are nothing new, but they are often difficult to set up or use in more hobby-oriented applications. The team of Ezra Boley and Finn Kuusisto is setting out to change this with their FANTM EMG Arduino Uno shield. It uses a series of conductive pads that pick up electrical signals from a user’s muscles […]

‘Droop, There It Is!’ is a smart irrigation system that uses ML to visually diagnose drought stress

Throughout the day as the sun evaporates the water from a plant’s leaves via a process called transpiration, observers will notice that they tend to get a little bit droopy. Also known as drought stress, this response to a loss of water results in low turgidity (internal water pressure) and can impact the ability of the […]

This sundial adjusts itself to compensate for daylight savings time and more

Some sundials are as simple as a stick pushed into the dirt, but they’re still reliable and accurate. The sun is, after all, quite consistent. But there are some caveats. The Earth’s orbit and its rotational tilt mean that the lengths of our days are variable and that means the simplest sundials are only perfectly […]

The Baldcorder is James Lewis’ tricorder-like device for measuring light levels and temperature

As part of element14’s Build Inside the Box Challenge, James Lewis (AKA Bald Engineer) decided to make his own DIY tricoder from Star Trek. In the series, a tricoder is a ubiquitous scanning tool that can perform various scans of the environment through its onboard sensors, as well as record and analyze them later — all in a handheld […]

Test and diagnose your USB cables with this Arduino device

USB cables come in a variety of shapes and sizes, with different internal connections that may be unknown to the user. For an easy way to figure out these connections, and to diagnose if the cable itself is faulty, TechKiwiGadgets has come up with the Arduino Cable Tracer. This device features an Arduino Mega board […]

Dual Screen Apollo DSKY simulates the Apollo Guidance Computer

NASA’s history is full of fascinating facts and trivia. For example, the Apollo Guidance Computer, which handled navigation and control for both the Apollo Command Module and the Apollo Lunar Module, ran with less RAM and processing power than a TI-83 graphing calculator. But reading that fact isn’t the same as actually experiencing the Apollo […]
