This first part of the proposed 4kva synchronized stackable inverter circuit discusses how to implement the crucial automatic synchronization across the 4 inverters with regards to frequency, phase and voltage to keep the inverters running independent of each other yet achieving an output that’s on par with each other. The idea was requested by Mr. […]

Make this SleepWalk Alert Circuit – Protect yourself from Sleepwalking Dangers
Do you have a habit of walking in night? Well, that habit isn’t that good, so one must try to get rid of it gradually. This article discusses a simple sleep walk alert circuit that might help you in getting out of this habit. By: SS Kopparthy Circuit Objective This circuit is a simple idea […]
Solar E Rickshaw Circuit
In this post I have explained a simple solar electric rickshaw or E rickshaw circuit which can easily built by anybody at home and used with a locally fabricated vehicle. The idea was requested by Mr. Amit. The Design Selecting a BLDC In one of my earlier posts I presented an idea which could be […]
Obstacle Avoiding Robot Circuit without Microcontroller
In this post I have explained a simple obstacle avoiding robot circuit without microcontroller and without using special motor driver circuits or ICs. The idea was requested by Mr. Faiyyaz The Design Basically it’s in the form of a moving vehicle which is able to detect and avoid potential obstacles on its path and change […]
Using Treadmill Exercise Bike to Charge Batteries
In this post I have explained how to use an exercise bike or a treadmill for charging a battery through a simple shunt regulator circuit with full charge cut-off feature. The idea was proposed by Mr. Peter Jaffe. Exercise Bike for Charging Battery I have been following your circuit tips for a little while. Very […]
Transistor Zener Diode Circuit for Handling High Current Stabilization
The high power “zener diode” circuit using transistor shunt regulator presented here can be used for obtaining a highly accurate, temperature and voltage stabilized outputs from high current sources, safely. Normal Zener Limitation The low power zener diodes that we normally use in electronic circuits are specified to work with low currents, and therefore cannot […]
