I don't altogether dislike the idea of using a big cap as a PS (as least it's better than a battery, which would have to be installed in a way that it's user-replaceable). But wouldn't 1 F be a problem? i.e. w/ 330 Ohm on the VCC pin on the palm, you get RC = 330 sec then x 5= a heck of a long time for the cap to charge up! Mind you the cap would then be pretty much a big battery when charged. Using 1000 uF as per Jose's rough math means tau = 0.33 sec which might be allright...hmm. Maybe it's time I sat at the bench and began the endless process of fiddling...
