Practical wearable computer, continued
Velo was powered by two AA bateries... Very easy to carry around
few more spares. Unfortunately zaurus is powered by Li-ION and only
lasts one day of my use. Fortunately, zaurus is very easy to charge
from USB (just build the cable, there's nothing in it), and cable from
ASUS wireless router works okay with zaurus, good. t68i can be also
charged from USB with simple cable.
Final question is how to provide USB power on the go, but 4
rechargeable AA batteries + piece of cable solve that one nicely, too.
Questions: how does zaurus's audio work? Is it possible to use
microphone and speakers at the same time? Why does audio break when
IrDA is enabled?

Mobile phones are very practical, and they start to be usefull,
too. With mujmail (http://mujmail.me.cz/
, or newer version in
www.sf.net/projects/javaphone) and html (again in javaphone), they can
actually be used for reading mail (and writing short mails, too). Web
browsing is also possible, and phones can be used one-handed while
working. You can also get SSH/ICQ/IRC clients, but good luck using
that on numeric-only keyboard...
Unfortunately: they just don't run Linux, and have all kinds of
ugly quirks. [Phone manufacturers, could you just use standard
connectors? You connect through USB, so why not just put regular
mini-USB connector there, and charge through it, too? What about
handsfree, 3.5mm jack should be enough for everyone, right?]
Questions: is it possible to charge nokia 6230 from USB port? Is
straight cable okay, or is resistor needed, or does it need more
Questions: how tolerant are recent notebook harddrives to
vibrations? I guess it is okay to walk with them while spinning, and
probably okay to run with them while powered down. iPod users should
know this -- do those harddisk handle jogging while in use okay?
Anyone ever took iPod to horseback riding?

I'm working on that... I'll need to get 2.6. to work on zaurus,
first, and that is not as easy as it would seem, because Sharp patches
were incredibly ugly in the first place. I already have 2.6.11 booting
(thanks to lenz's patches), but backlight, touchscreen and battery
charging does not work, yet; that makes machine unusable.
