In this post we are going to construct a musical organ circuit whose musical tone can be programmed by adjusting 10 pre-sent resistors in the circuit and the speed of […]
Simple Clap Switch Circuit using Transistors (Tested)
Below is a simple clap switch circuit for electronics amateurs which could turn on & off a bulb, Fan, Radio and so on., through the noise of clap. The sound […]
How to Make a Sequential Delay Timer Circuit
Within this publish we figure out how to create a basic sequential delay timer generator circuit that are available for obtaining a sequential initiating of a linked load, or may […]
Simple Latch Circuit using Transistors
All-purpose Latch-up Switch Normally a latch-up switch needs either a relay, an SCR trigger circuit or some integrated circuit. The simple latch- up switch described here uses only a pair […]
Automatic Signalling Circuit for Model Trains
Automatic railway signals are meant for efficient movement of trains, without colliding. The track is divided into blocks or sections. At the entry of each section there is a signal. […]
Simple Light Activated Switch Circuit
The light activated switch circuit works on a very basic principle, that of amplification of the current produced by a photo-transistor when light impinges upon it. The current is amplified […]
