In this post we learn about a circuit design which can be used for testing, or analyzing plant physiological behaviors and reactions to various external stimulation. That trees and plants have a soul has been known to plant lovers and gardeners for a long time. For all those who have never given this a […]

5 Input Microphone Mixer Amplifier Circuit using a Single IC
This circuit enables the user to blend in one 5 separate signals from 5 dynamic low-impedance microphones and a couple of external auxiliary inputs, which can be electret-type microphones or even actually amplified inputs for example those from your CD player or a phone. The circuit really is easy and is made up of feedback […]
Sine wave Generator Circuit using Wein Bridge Oscillator
The post narrates a simple yet accurate sine wave generator circuit using a typical Wein bridge oscillator A Wien bridge oscillator is actually a form of electronic oscillator which builds sine waves. It could possibly produce a wide variety of frequencies. The oscillator is dependent on a bridge circuit formerly formulated by Max Wien in […]
555 Timer Ramp Generator
The post explains how a IC 555 timer ramp generator circuit can be made using a single IC 555 and few other passive components When a capacitor gets charged from the source of voltage via resistor, the capacitor generates high waveform. The charging of the capacitor from a fixed source of current also generates ramp. […]
How to Design IC 555 Astable Circuit
The post explains how to design a IC 555 astable multivibrator circuit through formulas and calculations. Free-running multivibrator or Astable multivibrator is a circuit that generates rectangular wave. This circuit in comparison to others can run by itself i.e. it does not require any external trigger to run. However, in order to design the […]
Making an Electronic Tuning Fork Circuit
A typical tuning fork creates a note of 440 Hz, that may be, the global A (orchestral pitchl. lt is not really quite challenging to make an electronic tuning fork. A good oscillator, a divider, a loudspeaker along with a battery are generally that’s needed. To become beneficial, an effective ‘electronic tuning fork’ need […]
