The Arduino Light Controller is a passive output board designed to provide simple, reliable on/off control of up to 16 lighting channels using an Arduino microcontroller. The board routes Arduino I/O ...

Unlike DC circuits where you can simply lower the voltage or use rapid Pulse Width Modulation (PWM), AC voltage alternates at a fixed frequency (50Hz in this project). To dim an AC load, we use ...

There are plenty of “robot” projects out there that are really just a small remote control platform of some sort. We often like to think of robots of having some sort of autonomy though. [Luca Fagioli ...

Lasers, LEDs and light sources are devices that create light. LEDs (light emitting diodes) convert an electrical current into light using spontaneous emission in optically active semiconductors.

Organic LEDs are light emitting diodes (LEDs) that use polymers or small organic molecules as their optically active element. Development of organic LEDs is driven in particular by its potential as a ...

When it comes to deciding the fate of the planet, Colleen Golja always thought science and reason would have a seat at the table. That was until one morning last September in London, when the climate ...

As our beauty editor, I’m often asked by my friends about LED face masks. Do they actually work? The short answer is yes, but there are some caveats. These devices use various wavelengths, with red ...

What would you do with 25,000 hours? Because that’s about how long LEDs last and they not only make it possible to create more unique lighting designs, but they also save up to 85% on energy (save ...

1. The CosmicWatch Detector v3X is a compact, low-power (0.5 W) muon telescope that uses a plastic scintillator and silicon ...

Leaked details suggest the Samsung Galaxy S27 Pro and Ultra will be Samsung’s first flagships to feature DC dimming technology. Replacing traditional PWM dimming to reduce eye strain, the higher-end ...

We already heard word that Samsung Display is gearing up to start Galaxy S27 display manufacturing soon. That might have already happened; hence, these new leaks might be perfectly plausible.
