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 Drum Sound Simulator Circuits
In this post we talk about a couple electronic drum sound simulator circuits which can be used for replicating actual drum beat sound electronically, using a few op amps and few other passive electronic components. Using Capacitor as the Sensor Instead of Piezo Conventional electronic drum kits incorporate the use of piezo disc affixed to […]
Basic Electronic Circuits Explained
The article below comprehensively discusses all the basic facts, theories and information regarding the working and use of common electronic components such as resistors, capacitors, transistors, MOSFETs, UJTs, triacs, SCRs. The various small basic electronic circuits explained here can be effectively applied as building blocks or modules for creating multistage circuits, by integrating the designs […]
Electronic Touch Organ Circuit
An electronic touch organ is an intriguing musical device which produces very pleasant musical notes in response to finger touches on special touch sensitive electronic pads or buttons. Modern day organs are, however, very costly which usually places these outside the reach of the majority of folks. Low cost options types lack performance, and are […]
Electronic Voting Machine with SD Card Module
In this post I will show how to construct a circuit for an Electronic Voting Machine using Arduino and SD card module where the election data is stored in the SD card. UPDATE: This circuit has been upgraded to an improved version in which the results can be viewed over an attached LCD display, you […]
