Working schematic for gameboy color low battery indicator?

[friendofmegaman]

Hello there,

I've seen this thread viewtopic.php?f=7&t=3640 that seems to be suitable for the matter. But being a noob in circuit analysis I can't tell how do I tune the potentiometer. So I wonder did anybody implement low battery indicator in GBC and what schematics was used?

Thanks!

If I had time I would help,
I saw you posted this on ChipMusic.org,
Post that link to the low voltage regulator on there, a guy named Jazz should be able to help.

(I just skimmed through the thread but that link you posted should just need different resistors.

Basically, a potentiometer is a volume knob. I'm pretty sure that what you do is get your GBC to the point where you want the low battery indicator to light up, and turn the pot until the indicator turns on.

Yep, that's what I'm thinking, thanks
