 But why do you insist on a AA battery? You can actually buy for around 60
 shekels or a charger plus 4 rechargable AAA batteries, and each of those
 batteries lasts for around 10 hours of music playing for just one battery.
 Since a 256 MB player only holds about 4 hours of music, 10 hours is not bad.
 Especially when I consider that the first CD player I bought (around 1989)
 required 4 AA batteries, and could play just around 2 hours for one charge
 of the four batteries...

It depends upon what you want to listen to and how it is encoded. If you are
listenting to music in a quiet place then a 192k bits per second (24.5k bytes
per second) and you get three hours in 256 meg. Most likely you assumed 
128kbps MP3s, which are 2/3 the size. They would last four and a half hours.

If the player takes AAC (MPEG-4) audio encoded files, 96k would do, bringing
it up to 6 hours. Since what I really want to listen to is audiobooks,
a 16kbps AAC file would do nicely, which would go 36 hours. 

Since you can buybulk packs of 12 Everyready energizer AA batteries at
Office Depot for about the price of an 8 pack of the same batteries in
AAA, it quickly becomes a noticable difference. The best AAA rechargable
battery holds 800 mah, the equivalent AA battery holds 2200mah or more,
about three times.

The only problem I see with those numbersis that AFIK, the only cheap
MP3 player that plays AAC files is the Apple iPOD shuffle which is
ridiculously priced. In the U.S. a 512meg one sells for a competitive
$69, here it is about twice that, yet they are only taxed VAT.

My first CD portable player used four D batteries. In fact the 
battery cases were so rare that it took me six months to get one, and I
carried it around in a camera case with the batteries in seperate holders,
wired together. People laughed when they saw my set up, but when it started
to play (take off on an old piano joke). :-)

I don't know if any of the following players answer your original
specs, but Rockbox (www.rockbox.org) has AAC support on the iriver
iHP1x0, H1x0, H3x0 series, and on the iPod 4G, Color/Photo, Nano and
Video.

I've only used rockbox on Archos hardware but it is great, open-source
and feature filled jukebox software and is fully Hebrew-enabled.

This is getting way off-topic, but since we started this thread...

If you use rechargable batteries (and like I said, I bought 4 AAA batteries
and a charger for just 50 shekels), does it really matter that each battery
holds less charge? How difficult is it to change the battery every 10 hours
of listening, and always keep a few batteries charged for when you need them?

Of course, this assumes that you have intermittent access to electricity,
to charge your battery collection once in a while. If you can't get access
to electricity every week (say, in a month long hike in the jungle) then
I guess this can indeed become a problem because indeed alkaline AAA baterries
are very expensive,

Hmm, I didn't see in your original list of requirements that you need to
play AAC files. I have no idea what these are, and I doubt the cheap mp3
player that I bought a year ago plays that. But maybe the new ones do? Why
shouldn't they, when they already do almost anything concievable?

 My first CD portable player used four D batteries. In fact the 
 battery cases were so rare that it took me six months to get one, and I
 carried it around in a camera case with the batteries in seperate holders,

I also remember in the 80s, a lot of portable electronics used C, D and
9-volt batteries, and I had rechargable batteries (and a charger) for all
these sizes. It appears that today, only the AAA and AA sizes survived,
with the other batteries priced so ridiculously (e.g., 10 shekels for an
alkaline battery) that only a sucker would buy them. I don't think I bought
one C or D battery in the last 5 years...

Portable MP3 player?

2006-03-23 Thread Geoffrey S. Mendelson
Hi,

I'm looking for a portable MP3 player with the following specs:

1.  Linux friendly. I want to be able to manage it from a Linux system,
a GUI is not needed.

2.  No moving parts. 

3.  An LCD that shows song or file name.

4.  Rechargeable or AA batteries (NOT AAA).

5.  256meg or more of memory.

6.  Relativley cheap. I don't want a 3500 NIS pocket PC.

Any suggestions?

Thanks, Geoff.

AFIK the ones that run WinCE aka Win/XP compact edition can not. But I was
(mis)using the term to include generic hardware and I know some of them 
have Linux out of the box. I also think there are Linux ports for
some of the WinCE ones, after all they are very well documented and
use ARM chips.

there are a few sync utilities from pocketPC to linux. A friend of mine 
have used synce successfully to sync his WinCE powered phone to his
