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, […]
Electronic Load Controller (ELC) Circuit
In this post I have explained a simple electronic load controller or governor circuit which automatically regulates and controls the rotational speed of a hydro-electric generator system by adding or deducting an array of dummy loads. The procedure ensures a stabilized voltage and frequency output for the user. The idea was requested by Mr. Aponso […]
Electronic Scoreboard Circuit Using IC 4033 Counter
A simple multi-digit electronic score board system can be built using a basic 4033 IC counter circuit. The whole procedure is explained in the following article. So far we have learned quiet a lot about this interesting IC 4033 through the following posts that have comprehensively discussed the pinouts and cascading procedures of the chip. […]
5 Simple Electronic Dice Circuits Explained [Digital Dice]
We all know what a dice is and how manually a dice is shuffled and thrown to get a random number. In older times when we did not have computer games or mobile games, we used to play with various indoor games that required tossing a cubical thing called dice having 1 to 6 dots […]
