In this post we try to investigate the mains differences between alternating current (AC) and direct current (DC). The word AC and DC are pretty common with electronics and we all come across it while developing or dealing electronic circuit designs. Overview Though the terms are very ordinary with the field, many noobs become confused […]
Newly Updated Circuit Projects:
Customized Water Flow Controller with Timer Circuit
In this article I have explained a customized water flow controller circuit with timer.he idea was requested by Mr. Daljeet Singh Sokhey. Technical Specifications Right now I am working on a different project and would like your help. There are 2 inputs and both must remain high for a period of 30 seconds for the […]
Analogue Water Flow Sensor/Meter Circuit – Check Water Flow Rate
In this post I have explained a simple water flow meter/sensor circuit using hall effect sensor and a pulse counter circuit. Referring to the diagram shown below, we can see an arrangement consisting of a circular enclosure having a couple of pipes drilled in and a circular turbine shaped wheel installed inside the enclosure. How […]
Adding a PWM Multi-spark to Automobile Ignition Circuit
The post investigates a simple 2 pin oscillator circuit which may be inserted between the pickup coil and the CDI unit of a vehicle for achieving an induced multi trigger input in response to each signal from the pickup coil coil, this in turn is expected to enhance the sparking ability of the CDI coil. […]
Homemade Inductance Meter Circuit
In this article I have explained a simple yet accurate, wide range inductance meter circuit. The design utilizes only transistors as the main active components and a handful of inexpensive passive components. The proposed Inductance meter circuit can measure inductance or coil values accurately over the given ranges and as a bonus the circuit is […]
Deep Soil Metal Detector Circuit – Ground Scanner
In this post I have explained a simple deep under soil metal detector circuit for evaluating hidden metals such as gold, iron, tin, brass etc by detecting change in the resistance of the relevant soil layers. Bigger physical objects which might be buried within the topsoil could be unveiled through a modification in the electrical […]
