In this post I have explained about a simple battery current sensor with indicator circuit which detects the amount of current consumed by the battery while charging. The presented designs also have an auto cut off when the battery stops consuming current at its full charge level.. Why Current Drops as Battery gets Charged We […]

Laptop Charger Circuit from 12V Battery
In this post I have explained a simple car laptop charger circuit for charging laptops from a 12V car battery using a IC 555 based boost converter. The idea was requested by one of the avid readers of this blog. Making a 12V to 19V Converter May I request you for a circuit diagram for […]
3-Step Automatic Fast Battery Charger/Controller Circuit
Generally it is noticed that while charging batteries people hardly pay any special attention toward the procedures. For them charging a battery is simply connecting any DC supply with matching voltage with the battery terminals. A fast battery charger circuit charges a battery with enhanced speed so that it is charged in less time than the specified period. […]
Recovering Electrical Energy from Alternator and Battery
A request was sent to me by one of the readers Mr. Edward Pizzo, regarding solving a circuit issue. The idea refers to a very interesting concept of acquiring free energy through a mechanism which once initiated keeps running in quite a perpetual fashion. Using an Alternator and two Batteries A charged battery #1 is used initially for […]
Charging a Small NiMh Battery from Air
In this post we will try to investigate a circuit which can charge a small Ni-Mh battery by extracting free energy from the ether or air. I have explained more Discussing how to Derive Free 9V from Air – By Steven Chiverton Mr. Steven has devised an ingenious way of collecting energy from the air […]
Calculate Battery, Transformer, MOSFET in Inverter
In this post I have explained how to correctly calculate inverter parameters with associated stages such as battery and transformer, by calculating the matching the parameters correctly. Introduction Making an inverter all by yourself can be definitely lot of fun. However if the results are not satisfactory can completely spoil the whole purpose of the […]
