the Neo1973 has an unpowered small size USB port.
So for beening on the road, it could be nice to be
able to use a USB flash drive directly.

Our first idea was to hack the Neo1973 and give
some power to the port. 

Another idea would to solder some capacitor into the 
memory drive, maybe with a small swith.
The capacitor(s) would be charged like the Neo, via USB power.

I have one cheap USB flash drive with this

Power consumption during operating max 35 mA
Stand by 100 µA

Maybe with a small USB connector to avoid the need for an adapter
to use with the Neo1973?

What do you think? Would this be a good hack?
