Call us easily amused, but we think it’s pretty amazing what can be done with a microcontroller, some RGB LEDs, and a little bit of plastic. Case in point is [andrei.erdei]’s beautiful and quite ...

Compared to the Arduino Uno of old, modern microcontrollers are absolutely tiny — especially for the amount of processing power and I/O you get. But if you need something really small, like ...

UGREEN's DX/DXP NAS Series covers 2 to 8 bay NAS devices with a built-in system based on OpenWRT called UGOS or Debian called UGOS-Pro. Debian Linux or dedicated NAS operating systems and appliances ...

LED masks, which have light-emitting diode in the form of red, near-infrared and blue light, are still making wellness waves as one of the trendiest (and priciest) ways to revamp your skincare routine ...

Many people believe that the LED was discovered by US researchers working in the 1960s. In fact, Henry Round at Marconi Labs noted the emission of light from a semiconductor diode 100 years ago and, ...

CCFL backlights are the most common backlight technology and are used in displays ranging from 5.7 to 23 in. or more diagonal. They can have from one to 24 or more lamps mounted along the edge of the ...

Develop an IoT-based LED control system where Google Colab publishes MQTT messages and an ESP32 subscribes to those messages to control an LED wirelessly. This project demonstrates an IoT-based LED ...
