A deep blue organic light-emitting diode (OLED) developed by researchers at Science Tokyo operates on just a single 1.5 V, ...

Abstract: We proposed resonant-tunneling-diode (RTD) terahertz oscillator with offset slot-ring antenna for efficient radiation of second harmonic signal. From the theoretical analysis, output powers ...

This time I bring an electronic kit for beginners, this is a very cheap and interesting device that displays audio levels into the LEDs just like any audio level bar indicator will do. It is simple ...
