    So, if I understand this correctly, when the computer is off this device will power the GPS through the 5V of the floppy connector (which is probably linked to the 5V usb). Is that right? If not, is the device connected to the GPS some other way?

    This seems nice allright, the link says "Forbidden" though.

    I would like to have the Battery Voltimiter, just don't know if I'm up to gathering all the electronics to put it together. About the GPS, I don't think I'd mess with it because my GPS aquires a lock typically in 5-10 seconds (regardless of how long it's been off).

    His circuit CAN (doesn't mean it has to) power the GPS every hour or so for 3 minutes so as to not loose the "lock" of current location and be "warm" or "ready" when you actually get to turn on and use your carputer.

    it is that too! haha it's TWO projects in ONE circuit. One part is to measure your battery's volts the other part is to keep the GPS "warm".

    well.. I've only built support for this one, BUT he's supposed to have a parts list, board building instructions etc with the link above... If you find something cheap/simple to assemble let me know and I can definetely work on a support for it.

    Here is a picture of the above schematic, it's a lot easier on the eyes...This doesn't look nearly as bad now does it?
