Nuts and Volts magazine had an article within the
last 6 months I believe wherein the construction of an
mpeg player was detailed, which used flash storage.

Didn't buy it, but afterwards thought it might
prove a
useful read if I ever wanted to design a reader of my
own. I may not be the sharpest tool in the shed, but
there didn't seem to be anything terribly complex
about it.
I did buy one - very happy with it. Some SMT, which tends to scare
off some people, but all in all, an easy kit to build, with
easy-to-get parts (as of Nov, 2005). I was happy to have a 20x4 LCD
display on hand ($5 at a hamfest), and the exact shaft encoder in the
plans (there are others, even cheaper ones, but it was nice to have
the right one in my parts bin - from the Dayton Hamvention, years
ago). I did have to get the CPU and MP3 decoder and DAC new, but they
were easy to order from Digikey, et al.
Can't even remember what the circuit used
for brain power, but it must have been something
common and well documented.
