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 ...

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, ...

Efficient 1.55 micrometer light sources are needed for telecom and infrared photonics, but realizing them with perovskite quantum dots is challenging due to bandgap limitations. Li et al. used Er3 + ...
