yep...your right.... iwas too quick on the suggestion without properly researching my idea...

Had a very good look over Thoughtfix's hacks... the battery powered mint tin idea looks like a great one.... I'm goignt ogive it a go soon.... I also went though the comments on his page and think there could be a smaller build possible, with a different battery/s... if i could get it flat enough to attach to the back of the n770/n800 or in a small case that could also hold the external drive to keep the wires to a minimum....

i'll let you know when/if it happens
