So we are going to start an FBE (Flex Bleeding Edge) reflector to save
this reflector from technical talk about bleeding edge buggy development
code. I am beginning to wonder who is actually getting saved .......
(looking better EVERY day).

Hey Brian,
How about an Inverter from Radio Shack and run the Mac power supply
from 120 VAC converted from 12 VDC.

OK. You guys know I am am an Apple Fanboi. I will be using my MacBook
Pro to run the Flex for Field Day. But I need a way to power it from
12V as there will be no mains power at our site. No problem, just get
a DC power adaptor, right?
But wait, you *can't* get a DC power adaptor for the new MacBook Pro.
Seems that Apple has changed to their funky (and proprietary)
"MagSafe" connector that is held in place with a magnet so that, if
you trip on the power cable, it comes unplugged without damaging the
computer. Good idea.
But they own the rights to it so no one but Apple can sell you one and
Apple doesn't make a 12VDC power adaptor. The only solution is to cut
the cable from the Apple-supplied wall-wart to the MagSafe connector
and put a coaxial power connector in there so you can plug in a
third-party 12V switching supply.
Oh, I did find a company that would sell me one. The price was $135
and included a new Apple power supply in addition to the DC supply. If
you just want the MagSafe connector by itself, the price is about $90,
above the street price of an Apple power supply. I guess I would be
paying to have someone cut the connector from the power supply and
install the coaxial power connector for me. Oh, and they get to keep
the power supply.
Bad show Apple. If your stuff didn't work so well ...
