DIY PC Ambient Lighting Using Arduino and WS2812b LEDs

“Wanted some more depth for my gaming/movie viewing experience so here’s how I installed my ambient lighting. Before we begin, this project requires you to know how to use a soldering iron and some other basic tools. If …

High resolution without particle accelerator

“A visit to the optometrist often involves optical coherence tomography. This imaging process uses infrared radiation to penetrate the layers of the retina and examine it more closely in three dimensions, without having to touch the eye at all. This …

How to Make a Playable Arduino-based Drum Set With Beverage Can

“The drum set is a part of the standard rhythm section used in many music styles. The most usual type includes a bass drum, a floor tom, two tom-tom drums, also one or two ride cymbal, and a hi-hat. With …

Imec Reports Record Conversion Efficiency of 23.9 Percent on a 4cm2 Perovskite/Silicon Solar Module

“Imec, the world-leading research and innovation hub in nanoelectronics, energy and digital technology, and partner in Solliance and EnergyVille, today announced an improvement of its 4cm2 perovskite/silicon tandem photovoltaic module achieving a power conversion efficiency of 23.9 percent …

Interactive Laser Sheet Generator With Arduino

“Lasers can be used to create incredible visual effects. In this project, I constructed a new type of laser display that is interactive and plays music. The device rotates two lasers to form two vortex-like sheets of light. I included …

Lunar dynamo’s lifetime extended by at least 1 billion years

“New evidence from ancient lunar rocks suggests that an active dynamo once churned within the molten metallic core of the moon, generating a magnetic field that lasted at least 1 billion years longer than previously thought. Dynamos are natural generators …

New CubeSat propulsion system uses water as propellant

“A new type of micropropulsion system for miniature satellites called CubeSats uses an innovative design of tiny nozzles that release precise bursts of water vapor to maneuver the spacecraft. Low-cost “microsatellites” and “nanosatellites” far smaller than conventional spacecraft, have become …

Renishaw and Aeromet work to optimise high-performance alloy

“Renishaw and Aeromet International Limited today announce a collaboration to establish additive manufacturing process parameters and material properties for Aeromet’s A20X® aluminium alloy. Following a successful debut at the Paris Air Show, last month, the two companies are working …

RGB Electronic Die

“This project is an RGB Electronic Die that generates the codes from 1 to 6 through 7 RGB LEDs as outputs for showing the mentioned numbers while the inputs are the codes generated by a 7490 counter fixed to count …

Run and Jump Arduino LCD Game

“The Arduino is a really easy way to get started in electronics, it is simple to design a circuit around the arduino boards and easy to program using the arduino IDE. The arduino may not be as powerful as the …
