Ok guys,
I have put in download my serial voltmeter, full packet.
Read the README file.

Its work perfect with RR , tested in my carPC.

Good work

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).

yea i dont undestand why you need the gps in the equation?

**guino** · 03-05-2005, 01:08 AM

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.

oh so this isint a real volt meter? like monitor my cars voltage in RR when im driving?

**guino** · 03-05-2005, 01:44 AM

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".

**WebDog** · 03-05-2005, 02:05 AM

err, is their a simple voltage meter easy to build that will work with rr? since i have no idea how to read that above...

**guino** · 03-05-2005, 02:09 AM

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.
