More than one-fifth of US electricity is used to power artificial lighting. Light-emitting diodes based on group III/nitride semiconductors are bringing about a revolution in energy-efficient lighting ...

Use code FORBESVETTED50 to take an extra $50 off the Omnilux Contour Face, our pick for the best silicone mask. Red light therapy has long been used to reduce inflammation and improve skin texture, ...

Red light therapy (RLT) uses short wavelengths of red light to treat certain conditions. Though it seems promising, more research is needed to confirm benefits. RLT is generally safe but may depend on ...

Sometimes you’re looking for a component for a project that you know should exist, but you just cannot find it. Something like a 14-segment LED display, but not just one with a fixed color, ...

In every home I've had in the past decade, I've installed smart light bulbs. Over and over again, between four different apartments and one townhouse, I was impressed by how easy smart lights were to ...

This is a zephyr module that abstracts multiple sets of 3 Zephyr LEDs (GPIO or PWM (although PWM is untested as of yet)) behind the LED-strip interface. Please note when using GPIO each channel can ...

Abstract: In single-phase ac/dc light-emitting diode (LED) drivers, a reduced power processing technique is currently being used to increase conversion efficiency while reducing the size and cost of ...

This design generates PWM signals on GPIO pins 25, 26, and 27, that can be used to drive MOSFETs to control 'dumb' RGB LED strips (opposed to inteligent LEDs). I used the SI4944DY SOIC8 DUAL MOSFET ...

Abstract: Smart kitchen inventory management system (SIMS) is a system that is based on IoT, which will make managing kitchen, medicine, restaurant inventory more efficient and hassle free. This will ...
