In this article we investigate 3 simple yet powerful battery desulfator circuits, which can be used to effectively remove and prevent desulfation in lead acid batteries. The first method uses PWM pulses from a 555 PWM circuit using existing battery power itself, the second concept involves high voltage spikes, while the third design discusses desulfation […]
Newly Updated Circuit Projects:
Make this Solar Powered Fence Charger Circuit
A Fence charger or energizer is an equipment which is used for charging(electrifying) a fence or a boundary in order to protect the inside premise from human or animal interventions. Since these boundaries are mostly of large fields and parks, are normally away from the main cities, and powering them through some renewable option becomes […]
Make this EMF Pump Circuit and Go Ghost Hunting
EMF pump circuits are devices which are popularly used for the purpose of identifying paranormal activities or entities by generating rapidly rotating magnetic fluxes in the ether. The conventional devices use a spinning magnet fixed over a motor spindle, however these are mechanical types and are prone to wear and tear. Introduction The explained circuit […]
Automatic Inverter Output Voltage Correction Circuit
The common problem with many low cost inverters is their incapability of adjusting the output voltage with respect to the load conditions. With such inverters the output voltage tends to increase with lower loads and falls with increasing loads. The circuit ideas explained here can be added to any ordinary inverter for compensating and regulating […]
Make this Thermo-Touch Operated Switch Circuit
The circuit explained here employs a rather different approach for implementing a touch operated switch action. Here instead of the resistance, the warmth of the finger is used for sensing and operating the circuit’s output. Irrespective of the ambient conditions, our hands and fingers mostly exhibits some extra warmth or increase in the level of […]
Making an Adjustable Electromagnet Circuit
This article describes a simple circuit which can be used for pulsing an electromagnet. The IC 555 once again becomes the central part of the circuit. I have explained the making procedure of this simple adjustable electromagnet circuit for varying the magnetic power of an electromagnet. Introduction The circuit was requested by Mr.Jason, one of […]
