Re: need HELP with creating an extremely simple BATTERY CHARGING circuit for an LED flower!

i found this diagram

on this website
http://www.owlnet.rice.edu/~elec201/Book/batteries.html#SECTION001330000000000000000

it claims that it will automatically shut off charging when the battery
equalizes with the charge voltage with the use of the zenner diode
shutting off the base. i dont know. im not following it completely.
this might work if i also put a switch between the battery, wall, and
LEDs so that only either the battery or the wall provides power to the
LEDs.

i dont know. it still doesnt make much sense to me how it works, and
how i can use it correctly. oh well.
