Hi Dmitry,
would it be possible to code an underclocking tool like THclockDA for the Fossil, so you could set the clock to 16 or 30 MHz ?

Thanks

I performed the battery upgrade outlined on this site:

http://hamdomain.com/wrist-pda/index.html

My battery before this upgrade was lasting about 24 hours with no use at all, now it lasts about 10 days with regular use. Sure, it is a bit bigger... but that doesn't bother me at all. It was already a big watch, now it is just a little thicker. I much prefer not having to be concerned about it's battery going dead all the time to having it be slightly smaller.

I have two Fossil PDAs. I use one of them all the time and keep the other for backup. I've only ever had need of the other one once when I put a program on that kept crashing and freezing it and I couldn't delete it. So I discharged the battery and synced it up again a couple of days later.

I still use my UX50 alot especially for sending email, surfing and editing documents on the move. But most of the time the fossil does the job pretty well.

I have one. I don't sync all that often and really just use it as a watch; as long as I charge it every other day!

Anyone interested in this?:

surely you kid me, even at 66 mhz it seems slow, i'd rather clock it at 120

For me too, ts more important to get a longer bettery life than have the apps faster. Will DynaClock work it?

dmitry, IMHO the low speed is the fault of the ultrachip whichn is set to update the screen very slowly...

@Dmitry
First of all, thank you for answering !



Absolutely not kidding, i'm a long time reader on this forum and RESPECT your work a lot !
As a Fossil owner you will surely know how terrible the battery-runtime is, so my intention is to find out, how to get it longer. There are two possibilities, first higher battery capacity means Case-Modding; second somehow underclocking the CPU.



Alright, that's your opinion, but when you take a look at the Palm m500 series, they got also OS4 and are IMHO with 33 MHz-CPU fast enough. So correct me, if I'm wrong.
(Plus I have read somewhere, that results with Speedy shows, that the Fossil doesn't run at 66, but at 45 MHz.)


And the main reason, why I'm especially talking to you is, that you're the Man who makes the Impossible possible !

Hi Tam,
checked out your blog for the Fossil, very nice and informative !

I've done some Benchmarks to confirm your statement. These are PalmPi for CPU-Speed (as introduced on your blog) and PalmInternals "Speed Test" for Systemperformance. As in my last Post to Dmitry suggested, i compared the Fossil Abacus with Palm m515.
(both Devices don't have any Hacks or equal installed, that could influence the measurements !)

Here are the results:

[1] PalmPi (sec)
[2] PalmInternals (Time in tics/sec)

Palm m515 (OS4.1, LoRes, 33 MHz Dragonball VZ)
[1] 15.35
[2] 488/5

Fossil Abacus (OS4.1, LoRes, 66 MHz Dragonball Super VZ)
[1] 8.99
[2] 1680/17

Clie SJ33 (OS4.1, HiRes, 66 MHz Dragonball Super VZ)
[1] 7.82
[2] 311/3

For better comparison I'll do the same Benchmarks also on the SJ33 (SuperVZ-CPU) later, but first have to awake it to life
...back to life

FullACK. I did the part I can do. Look my post about Batteries.
I have now a supplier for the LiPoly Batteries as well as the Ptototype of a modded backplane, which is only 2-3mm thicker and gives a 490mAh Capacity.
Next step is to make a closed mold, which will allow me to repruduce this backplane and offer ist together with the Batteries.
Please look my post (linked above) and tell me what you think

Hi,
IMHO, there is a way to tell the UltraChip to update with the highest possible FPS - but every app needs to do this on its own.

Hi,
correct me if i'm wrong, but is this "UltraChip" something like a Graphicscontroller and where exactly are the settings located ?
Wouldn't it be possible to change the FPS for the hole system and how ?

Say, it could be done, so it would speed up the Systemperformance means better results in PalmInternals and also better compatibility with OS4-Software, but less battery-runtime.


So as a summary, this must be done to get an optimized Fossil:

- Increase the FPS
- Underclock the CPU
- Higher Battery (which is already done )


I wish, there would be more interest on this discussion, so any comments or suggestions are welcome !

Tam Hanna

Hi,
the UltraChip is the controller between CPU and screen that allows the CPU et al to turn off in watch mode(AFAIK).

The call for setting the FPS is in the sdk - are you interested in me hacking up something?
