This step down buck converter will convert a 220V AC input from mains supply to 5V or 12V or 24V DC with 90% efficiency. The proposed buck converter is an SMPS circuit using the IC VIPer12A from STMicroelectronics. The circuit uses negligible number of external components yet is able to operate directly from mains AC input. The Buck […]

How to Control Motor with a Cell Phone
In the following post I have explained a very simple circuit idea which can be used for controlling a motor’s rotational direction i.e. for moving it either clockwise or anticlockwise through alternate miss calls from your cell phone. The Circuit Concept I have already discussed a novel cell phone controlled remote switch circuit where the […]
LED Fader Circuit – Slow Rise, Slow Fall LED Effect Generator
In the following post I have explained a simple circuit which can be used for alternately switching LEDs with gradual brightening and fading effects. Circuit Operation The circuit can be effectively used for generating spooky effects in idols, for example it can be used for illuminating the eyes of a Jack-o’-lantern during haloween celebrations. The […]
