There are some projects that seem at first sight to be easy, but anyone who tries them finds a whole heap of unexpected problems and turns to the off-the-shelf device. PCB antennas for example, or ...

Jim Bruges' Rubber Duck-ify instant camera uses an Arduino to edit photos with local AI and print them instantly on thermal ...

Using a new method to make organic light-emitting diodes (OLEDs), researchers produced this image of a macaw—the highest-resolution multicolor OLED image produced to date. The image is 300 by 430 µm.

We've had someone pop round to provide a quote for a monitored alarm system, and it's quite something. I don't want to pay ...

We’ve tested a variety of popular models to find the best flashlights, whether you’re looking for one to use in the midst of a blackout or simply want to put a decent one in the glove box of your car, ...

A low pulse on this pin (below 1/3 of VCC) sets the internal flip-flop and makes the output go HIGH. When the voltage on this pin reaches 2/3 of VCC, it resets the flip-flop, and the output goes LOW.

Welcome to our blog post on interfacing the WS2811 (5V) RGB LED strip with Arduino! In this guide, we will walk you through the process of connecting and controlling WS2811 LED strips using an Arduino ...

Integrated circuit (IC) chips are dirt cheap these days, which means we makers have a tendency to rely on them even when they aren’t completely necessary. With affordable development tools like ...

Remora is a simple pseudo animation language that works as a companion to ORCΛ receiving UDP short instructions and sending animations to addressable LED stripes. This animations run entirely in the ...

It was an interface that launched a thousand hacks. Near trivial to program, enough I/O lines for useful work, and sufficiently fast for a multitude of applications: homebrew logic analyzers, chip ...
