The SilentSwitcher, A Quiet Mains-free Power Supply

Electronics News Updates / By Ibrar Ayyub

Audio projects become smaller over time with the rapid advancement of technology. A traditional power supply is still considered large compared to audio projects size constraints and it may not fit such delicate applications that need to deliver a good sound with zero noise. Jan Didden, audio specialist who is known for his own publications

LIGHTING UP A VERY WIRY CANDLE

News & Updates / By Ibrar Ayyub

Entries into the Circuit Sculpture Contest tend to be pretty minimalist by nature, and this LED candle by [Amal Mathew] is a perfect example. The idea here was to recreate the slim and uncomplicated nature of a real candle but with a digital twist, and we think he’s pulled it off nicely with a bare minimum

MCU based LED Arduino VU Meter

Electronics News Updates / By Ibrar Ayyub

From time to time, I see people trying to build an audio VU meter. In the analog era, that’s typically done with a voltage divider + a series of comparators; or using chips like LM3914/3915. Those chips are harder and harder to find, or you may need more resolution, or a different output profile. What
