hey ladyada,
I was just wondering what configuration you would personally use for the low battery indicator. Currently I am using the one below by 'aclight' on the forums but it doesn't seem to work with the iPhone/touch. I am testing that fully tonight, I know that a minty boost with 100k resistors and the below LBI config won't charge, so I'm desoldering the LBI components and trying to charge my touch again.
But I was hoping that you could help me out here.
Thanks alot!
Mike

R1 is 113K DigiKey RHM113KFCT-ND
R2 is 249K DigiKey RHM249KFCT-ND
R3 is 200 ohms DigiKey RHM200FCT-ND
LED1 is a DigiKey P563 or any 25mA LED, any color.
Note that R3 (200 Ohms) has physically moved to just below the LED1 pads.
It is soldered to PIN 1 of the USB connector X1 and the pad junctions of LED1 & original location of R3.

Hi Moses_410, I was wondering if you've had success with your setup on your IPT? I'm sorta running into the same problem with my touch too...

Ladyada, I built a mintyboost last week for a friend who has an iPhone. Her firmware is 1.1.2
I built the full kit and used the 100k resistors and used pullup mode. Tested with multimeter and was reading 5 volts out. It charged a ipod mini.
She tested it this weekend using rechargeable nih batteries and they are 2500mAh batteries.
When plugged in it showed charging and after some time icon changes to fully charged then it actually loses a lot of charge if still connected. She left it on all night and it was nearly empty in the morning.
