Transformerless Power Supply Generating low-voltage DC from the 220V or 110V AC mains is very useful and necessary in the field of electronics. Low voltage DC, like 5v, 6v, 9v, 12v, is used in electronics circuits, LED bulbs, toys and many household electronics items. Generally, batteries are used to power them, but they need to be replaced from time to time, which is not cost-effective and also takes… |

Digital Dice Circuit Dice can be used to play several games, such as Snakes and Ladders, Ludo, etc. Generally, dice are made of wood or plastic, which gets distorted over time and becomes biased. A digital dice circuit is an alternative to the traditional dice; it can’t be biased or distorted, and it acts so fast that nobody would be able to cheat. This guide will explain how to build a digital dice circuit… |

Clap Switch Clap switch is an interesting hobby circuit that turns on the lights with a clap sound. Although its name is “Clap switch”, it can be turned ON by any sound of approximately the same pitch as a clap. The main component of this clap switch circuit is the Electric Condenser Mic, which has been used as a sound sensor. The Condenser Mic basically converts sound energy into… |

Fire Alarm Circuit using Thermistor Fire alarms are a prime necessity in modern buildings and architecture, especially in banks, data centres, and gas stations. They detect fire in the ambience at a very early stage by sensing smoke or heat and raise an alarm, which warns people and gives them sufficient time to take preventive measures. It not only prevents big losses caused by deadly fire but sometimes… |
