Hi all,
I'm in the process of putting an ipaq into my glider. My ipaq uses a
USB cable for all power/data etc.. It has the smaller plug on the unit
and the larger (normal) USB plug into the power source. I want to chop
off the larger plug so I can run the lead straight off the panel.
The USB cable has copper, silver, red, black, green and white wires.
It's probably obvious but "just in case" can someone please confirm
that the black is negative power and the red is positive power? I
don't want to blow my HP Ipaq up, I have been caught out before!

You need to be very careful - all iPaqs that I know about do NOT use 12v
- they use about 5.3v (iirc). So you cannot connect the glider 12v
supply to power your iPaq - at least not directly.
What I did for my (original) set up was
1. Take the GPS and iPaq you will be using to someone like Johnny
Appleseed - (they are here in Brisbane and I think elsewhere as well).
2. From the dealer, buy a premade cable that plugs into your GPS and
your iPaq - and also has a 12v car charger to provide power to
both. If you are using FLARM as the source, you don't have to
power that specially, but you will need to do a bit of soldering
to get the data from the FLARM to the iPaq.
3. Remove the innards of the 12v to 5v power supply and buy a small
project box from Dick Smith to hold this. Connect the glider 12v
on the input side and you are done.
