drgeoff,
I really appreciate your comments.
I looked up the meaning of weedy and this cable is definitely weedy.
My Pi shipped today and I should get it Monday or Tuesday.
I found this picture of a Pi:

I see the large contacts by the phono socket.
I was thinking using the positive and negative contacts by FD3 (upper left by the Micro USB connector).
Is this OK?
There is an open space on the board to the right where I can super glue the barrel connector.
Hopefully it will fit an open case like this:

When I built this cable I didn't want to deal with soldering thin wires.
I exposed the USB contacts and soldered the female barrel connector to the contacts.
I checked the polarity about 3 times.
I will check again before using it with the Pi.
I did some reading last night and this is turning into a learning experience.
They recommend a .75 AMP PSU for the Pi.
My PSU is almost 3 times that at 2 AMP.
More power is not a problem, the device will only draw what's needed.
Again, is this correct?
My cheap cable will have more resistance, so less power will get to the device.
I decided not to use my WiFi adapter, reducing the power requirement.
I'm not going to use any peripherals on the Pi.
I will use software apps to update/monitor the Pi, further reducing power req.
See:

Any faults with my logic?
I have another option and might try this first.
I have a tablet that I only use when we travel.
It has a 5v 1.5 AMP PSU.
It's about twice as heavy as a cell charger and the cable is shorter and about 50% thicker than the cable I'm using above.
I could use this PSU with the Pi and use above PSU with the tablet.
I tried and it does recharge the tablet.
Thanks again!
