Guest columnist Naoyuki Kobayashi, senior product manager at Murata says that one problem frequently encountered when designing LED lighting circuits is that the capacitors in the circuit experience ...

Schematic and operation of a capacitorless active-matrix micro-LED pixel, where a single memristor (1M) substitutes both the storage capacitor and the driving TFT. The compact 1M cell can be ...

Due to the advantages like low voltages, long life, cheap, reliable, fast on-off switching etc, the LED’s are used in many applications. The various applications of LED are, All kinds of visual ...

Here is a simple and powerful LED circuit that can be operated directly from the AC 100 volt to AC 230 Volts mains supply. The circuit can be used as mains power locator or night lamp etc.. The ...

Teardowns of cheap electronic devices can produce results that are interesting, horrifying, or both, especially when mains power is involved. [bigclivedotcom] gave a minimalist LED lamp his reverse ...

With their low equivalent series resistance (ESR), which allows for good ripple-current handling as well as high surge-voltage ratings and self-healing properties, film capacitors are strong ...

With cycling safety in mind, I bought a pair of low power red LED things that replace the bungs in the end of drop handlebars. They are a neat way to get a bit of extra visibility – and to give a ...
