Make an Electronic Candle at Home Circuit
The proposed electronic candle circuit does not use wax, paraffin or flame, yet the device perfectly simulates a conventional candle. Basically it incorporates ordinary electronic parts like LED and battery. The interesting part of it is that it can be extinguished with literally a puff of air. The proposed electronic LED candle circuit helps you […]
Mains 20 Watt Electronic Ballast Circuit
In this post I have explained a simple 20 watt fluorescent ballast circuit using a single chip FAN7711 from Fairchild semiconductor. The proposed mains 220V operated, 20 watt fluorescent ballast circuit is built around an LCC resonant tank and a half-bridge network. Implementing Zero Voltage Switching The main features and operations may be understood with […]
4 Universal Electronic Thermometer Circuits
Here I have explained four best electronic thermometer circuits which can be universally used for measuring body temperatures or atmospheric room temperatures ranging from zero degrees to 50 degrees Celsius. In the previous post I explained some of the features of the outstanding temperature sensor chip LM35, which gives outputs in varying voltages that’s directly […]
Electronic Ballast Circuit for UV Germicidal Lamps
In this post I have explained the construction of a DC UV germicidal lamp ballast circuit which can be used for driving any standard 20 watt UV lamp through a 12 V DC source. Although, the proposed ballast design was originally meant for illuminating a regular 20 watt fluorescent tube light, this can be also […]
Electronic Acupuncture Circuit [Bio-Stimulation Circuit]
In this article I have explained how to build an electronic acupuncture circuit, also called bio-stimulation circuit., and use it for a possible treatment of many common body ailments, without any side-effects. The unit, if built and implemented correctly can possibly provide impressive results in healing issues related to headaches, body pain, muscle pain, fatigue, […]
