Witam, Wykonuję modyfikację pewnego urządzenia, dodając zewnętrzne zasilanie. Aktualnie działa wyłącznie na baterii 9 V. Bez wchodzenia w szczegóły. Układ zasilacza standardowy! Tzn. pierwotnie układ ...

In a previous article, we explored the behavior of an LED diode as a small light source. We have seen how important a protection resistor is to light up this component. In this article, we will ...

OLED (Organic Light Emitting Diode) and Mini LED represent two of the highest-end display technologies available today, but they work in fundamentally different ways. OLED panels are self-emissive; ...

Optical interconnects have attracted much research attention in recent years owing to potential performance and power-consumption improvements over traditional electrical connectivity. A complete ...

I needed a pulsating light for a certain signaling. Voltage was 230V. So I decided to make a simple circuit, consisted of a LED diode, two capacitors, two resistors, a diac and a diode. Activity of ...

Both LCD TVs and LED TVs have been on the market for many years. TV-size LCDs gained popularity in the mid-2000s, while LED TVs followed a few years later. The marketing departments for many companies ...
