im trying to follow the calculations and how the current flows to each
component, but i cant.
its too confusing for me. i keep thinking that the resistor that
limits the current to the battery to 6mA also limits the current to the
LEDs to 6mA since they are in series with the resistor, while plugged
in. actually, did you mean for the adapter to be only used for
charging? that would make sense then. i still dont get how the 317
limits takes the voltage down to 4.3v. i thought it only limits the
current through the adj pin. and how does this stop the batteries from
being overcharged?
i dont know. its too much for me.
maybe ill just leave out the battery part altogether.
thanks for helping out. i really appreciate it.
i wish i hadnt thought about using batteries in the first place. would
have saved me 20 hours of worthless internet browsing.
