Hello everyone 
I decided to build this charger for my lead-acid batteries because I'm sick of simple superfast inreliable battery-blow-up chargers.
I have all the components, programmer, some experience of PIC design and programming ( )
But I can't find this current transducer ( LTS25NP ) in Bulgaria, and purchasing it will cost a fortune. Does anyone know how to make a transducer with a coil and opamp? ( I need some idea of a circuit and formulas for the coil, or a link to a page with such formulas etc ). Any help will be apreciated. And if someone can think of a cheaper and more popular similar IC - post please! It could be available in the local shops
