In the article below I have explained a compilation of simple yet accurate motorcycle voltage regulator circuits, which can be used for regulating the varying alternator voltage into a fixed DC voltage. Voltage regulator circuit is very important in motorcycles and two wheelers since they ensure a regulated battery charging thus keeping the battery safe […]

How To Use And Program ATmega Microcontrollers From Scratch Without Arduino
ATmega microcontrollers, they are coming from the AVR family which Atmel developed long back, and later this Atmel company was taken by Microchip. So now officially Microchip owns it but still people say Atmel AVR only. These MCUs became very popular slowly because they are easy to understand, quite affordable, stable in long run and […]
Opamp Hysteresis – Calculations and Design Considerations
In most automatic battery charger circuits in this blog you might have seen an opamp with a hysteresis feature included for some crucial function. In the following post I have explained the significance and design techniques for the hysteresis function in opamp circuits. To learn exactly what’s a hysteresis you can refer to this article […]
Op-Amp Hysteresis Resistor Calculator
Many times you make simple op-amp comparator circuit, but output starts jumping up and down like anything near the triggering point just because of small electrical noise. Relay and microcontroller will get totally confused with this nonsense. Only proper solution is adding positive feedback to make it a Schmitt trigger. But doing paper maths for […]
Accurate Monostable Timer Circuit using IC 4538 (CMOS)
This circuit is basically a simple yet extremely accurate push button monostable timer using one half of a CD4538 dual monostable multivibrator IC. It works as a one-shot timer, where one press and release of S1 produces one timed output pulse. This pulse turns ON the BC557 transistor and the LED for around 7 seconds, […]
10 Simple FM Transmitter Circuit Diagrams Explained
An FM transmitter circuit is a high frequency wireless device which is able to transmit voice signals into atmosphere so that it can be received by a corresponding FM receiver circuit for reproducing the voice signals in a loudspeaker. Here we’ll discuss how to build small FM transmitter circuits using 10 different methods, one that […]
