low battery indicator circuit schem link

Is this right? I did a quick check for the R values, 1M and 100K as Brett stated works, so do the shown value of 100K and 10K.  A constant 10:1 ratio for this type of voltage dividing? (6V down to .6V, etc.)

U could make the LED blink.
that would save power by at least half.
this technique has been done many times in the past.
what about a blinker that blinks slower or faster
as battery voltage drops?
the LM3909 is well known flasher IC.
Could use a CMOS 555 also.
The 3909 uses less parts 2 flash.
then there's always the self-flashing LEDs.
just add power, and limiting resistor, and they blink forever.

Hey Peter, gettin' the ole' red X at your pic...

Sorry, my Windoze box died.  :cry:

I'm using my 1997 Mac right now. I'll get it back as soon as I can.

Take care,
