C1000/3x00 General discussions / Usb External Cd Drive

Nothing specific, I just plugged in and the usb-storage module loaded (I am using the cacko beta rom).
after that, mount /dev/scd0 /mnt/usbstorage and viola!
fortunately cdrecord is included in the package so I did cdrecord --scanbus which detected my burner. Haven't tried burning yet.

That's exactly the kind of simplicity I was hoping for. When I buy my enclosure, maybe it'll be that easy.

I think the new ATA protocol *is* scsi commands over ATA. or something similar.
Anyway, got a USB cdrom to work on my C3000 - the Freecom one (grabbed cheaply off ebay; paid expensively for the delivery .
I will let you know what cdrecord yields.

What did you do to get your CD drive working? I'm pretty sure that an enclosured internal drive and a pre-made external drive would act exactly the same in terms of the data going throught the USB connection, so your experiences would definitely be a useful contribution.

C1000/3x00 General discussions / Sl-c3000 Vs. Sl-c1000 Vs. Sl-5500
« on: June 09, 2005, 10:54:11 pm »
I used to own an SL-5500, then sold it, then bought an SL-C1000 a few months later.

I originally sold my SL-5500 because I couldn't deal with it anymore. Due to a sizeable bit of stupidity during the first few days I had my 5500, I plugged it into a 6V power supply, which blew the internal battery charging mechanism. The rest of the unit was fine, but I had to buy an external charger for my battery.

However, there were other things that I disliked about the SL-5500:
It did not have a fast enough processor to decode well-encoded DivX movies (one of my main intended uses) or to run emulators well (another of my main intended uses). The contrast of the screen was poor, and when trying to show different shades of black it would get all messed up. The screen resolution was not too great, especially when trying to view webpages. The keyboard was a bit too small for me to comfortably thumb-type on. The internal flash was not large enough to hold all the programs I wanted to install - I had to reformat an SD card and use it for applications. One of the hinge connectors on the plastic screen cover broke, and I had to super-glue it back on, but the cover was still loose so my screen got dirty.
Most of all, the battery life on my unit in particular was abysmal. I bought it used from a friend for a really low price, so it may have been that my battery was nearing the end of its lifespan, but I was rarely able to get over 1 hour of use out of my unit.

So on to my SL-C1000 - it is everything I wanted the SL-5500 to be. The processor is fast enough to run emulators and play movies, the screen contrast is noticeably better (more on that in a second), the resolution is impressive and is just right for web pages, the keyboard is bigger, the internal flash is large enough to hold all my applications, everything on the unit seems very sturdily constructed (I did worry before buying the unit that the flip-around screen would perhaps become weak over time, but the hold flip-out and around mechanism feels so solid that I'm not worried about that anymore), and the clamshell design keeps my screen from getting too dirty.
And, most of all, I am astounded by the battery life. In order to test the life, I devised what I like to call the Lord of the Rings video stress test. I ripped LotR - Return of the King, compressed it to a 700MB DivX file and copied it to my 1GB SD card. I then charged my SL-C1000, put it on full brightness, connected my Shure E2C earphones, turned the volume up to a reasonable level, and opened the movie in mplayer with a Kino2 frontend, bvdd drivers installed. I was expecting my Zaurus to run out of batteries 2.5 to 3 hours into the 3:20 movie. That did not happen. Instead, it made it all the way through the movie, then through two 20 minute episodes of Futurama, then about 10 minutes into some light text editor use, before it finally turned off. The total run time, with the screen brightness on full and the sound in my headphones on, playing DivX from my SD card, was 4 hours and 15 minutes.
The only thing that dissapoints me about my SL-C1000 is that the screen is so very hard to read in direct sunlight. Note that it is still quite useable on a bright summer day outside in the shade, but if I'm trying to make a note or something while walking around outside, it's a bit difficult. Many people also complain about the lack of internal wifi, but Wifi CF cards are a cheap and effective solution to that problem. I suppose I should note that my SL-5500 was no better at showing the screen in direct sunlight, but I believe I have read that SL-6000s use a different screen lighting technology that looks much better in intense external light.

Apart from everything I didn't like about my SL-5500 being improved, I enjoy the SL-C1000's new features, too. It looks nicer than the SL-5500, the flip-around screen, though I don't use it much, is still useful on many occasions, the keyboard is not only bigger but has more keys, which makes entering non-alphabetical characters easier, and, of course, the USb host is quite awesome. You can hook up any keyboard easily and it will instantly be recognized. External USB can usually be used with little hassle, as long as you set thing up first, and I am exploring more exotic peripherals such as external USB drives and webcams.
My favorite peripheral is my iRiver ihp-120 20GB mp3 player. I was able, after mounting it via the command line, to connect my music player as an external hard drive and use it to store more than one full-length movie while on the go.

In short, the SL-C1000 is a wonderful machine, and with the USB host port available on all of the four-digit SL-C models, the 4GB internal hard drive is not really that important. As long as you can manage to spare enough money for the SL-C1000, definitely go for it. If you can't get enough money together, I would recommend at least buying an SL-5600, with a faster processor and almost twice as large battery.

All that being said, I don't think the SL-5500 is a bad machine, and if I had bought one new and had been less clumsy and stupid with it, I might still be using one.

Also, if you do decide to get an SL-C1000, I would highly recommend StreamLineCPUs/TriSoft, who do a great job with english conversion, offer incredible support, and, though they are not as cheap as pricejapan.com or conics.net, are still significantly less expensive than Dynamism.

(Hope that wasn't too long)

P.S. - The SL-C3100 won't be out until June 24th, so it wouldn't be available at places like Dynamism right now.

C1000/3x00 General discussions / Amazing! My C1000 Is Un-bricked!
« on: June 03, 2005, 03:18:40 pm »
I usually try and find the absolutely lowest price for anything I buy on the internet, but for my new SL-C1000, I decided to go to StreamLineCPUs even though their price is higher than most (probably because it's the cheapest place that actually accepts credit cards). I was initally impressed when they sent me a custom-written English manual, more impressed when they included a USB host cable that I was not aware they were including, and also impressed by the extra applications they installed for me.
So I guess it's no surprise to hear how awesome TriSoft is with PR. Hurray for StreamLine/TriSoft!

C1000/3x00 General discussions / Usb External Cd Drive

It should be that easy.

Note that (iirc) you'll need some kernel modules to run the cdrom drive (on top of the standard mass-storage ones).

You'll also need to have the appropriate fs modules compiled (or do they need to be compiled in?) so that you can actually mount the disk once it's recognised as a mass-storage device - joilet, ISO 9660, UDF, etc.

Ah, this is what I was worried about. I know enough Linux to cd my way around system folders and follow directions successfully, but more advanced things like adding modules and compiling kernels are a little beyond me. However, since it should be possible and would be really cool, I'm gonna go ahead and buy an enclosure for my laptop drive anyway. I suppose I'll bump this thread after trying and failing to get it working by myself.  

Laptop CD drives only cost ~ $40 (my DVD+/-RW slim drive cost ~ $120), and an enclosure is about $30, so if my plan here works the cost of an external CD drive for the zaurus could be as low as $70, which is very cheap for a storage solution with such great potential. I only wish I could get a slim 8cm CD drive and tape it to the bottom of my zaurus, but, alas, I cannot find a single 8cm only CD drive in existence.

C1000/3x00 General discussions / Safe Files On Cf Card
« on: June 03, 2005, 01:03:20 am »
This is how it is done on my SL-C1000 with the standard Sharp ROM:

Insert a CF card of sufficient size
Go to the Settings Tab
Select "Backup/Restore"
Select the Backup option (if it's not already selected)
Under "Media", select "CF Card"
Press Start

I'm pretty sure this standard backup saves your entire internal memory, so it would include any address book contacts from any program. I've used it on the default Sharp address book program and KA/Pi. It should be noted that after Restoring, any non-backed-up changes would be lost.
If you want to save the address files to a CF card for some other use, I'm not sure how to do that. It would probably depend on what you intended to use them for.

By the way, the present tense verb you are looking for is "save". "Safe" is an adjective.

C1000/3x00 General discussions / Usb External Cd Drive
« on: June 02, 2005, 11:11:14 pm »
I've heard talk of USB Flash drives, music players attached via USB, webcams, cameras, and all other sorts of gadgets being attached to the SL-C?000 USB port. However, I don't think I've yet seen a discussion for external CD drives. Now, of course, you would need an external power source, and you probably wouldn't get very high read/write rates, but how viable is this external storage solution for the Zaurus?

The reason I'm interested is because I have a slim laptop DVD drive that I was using in my custom-built mini computer, but have moved to a regular sized computer case and don't need my laptop drive anymore, and was thinking it might be fun to buy a USB enclosure for it and connect it to my SL-C1000. However, I don't want to get an external enclosure unless I think I have some chance of making it work.

Does anyone have any insight into or previous experience with something like this? Would it be as easy as plugging the drive in and mounting the CD, or something more difficult?

Accessories / more battery for my zaurus
« on: April 25, 2004, 07:11:40 pm »
Here are the two options I considered.
A: The DPS-9000+, made by digipower, is a rechargeable 7.2V battery, with connectors to almost any digital camera and every PDA, including a 5V voltage step-down connector; around 6000mah, I think. I haven\'t ever used or seen one of these, just pictures on the internet and some guy\'s website saying how he has one (search for zaurustuff in google and you\'ll find it.) On eBay, you can et one for $40-$45, but for ~6 extra hours of battery life, that\'s a pretty good deal.

B: Homemade external battery pack. Yeah, I suppose you could buy a $17 battery pack on the internet, but you can also buy a $2 battery holder at teh radioshack, get a fitting plug from an old unused AC adapter, or buy a plug from the previously mentioned radioshack for ]$1, solder it together, and you have youself a battery pack that will work fine for 1.2V batteries. For 1.5V batteries, connect an N4001 diode (also found at the shack) into your circuit.
The 1.2V NiMH batteries you will want to use in your pack are not too expensive. I got 4 2300mah batteries and a 3-hour charger new on eBay for $16 including shipping, and they work like a charm. You can add other features to your battery pack depending on how much money you\'re willing to spend, how much time you\'re willing to put into it, and how much experience you have with this sort of thing. It is possible to make a pack that uses 1.5V and 1.2V AAAs, AAs, 4/3A\'s, Cs, Ds, can switch polarity to charge the aforementioned 1.2V batteries from an AC adapter or a USB port, has many different cable extenders, velcroes to the back of your Zaurus, and has your girlfriend or boyfriend or husband or wife or favorite celebrity\'s face painted on the back. It\'s all up to you. I just made a 1.2V AA extender, and just recently I spent 2 hours on the way home from Six Flags watching Futurama from my CF card with the light on full and my extender did not even run out, not to mention the internal battery still being full. In addition to high-capacity NiMH AA\'s (don\'t use NiCads, they suck), you could also get some 4/3A size rechargeable batteries - they are only slightly larger than AAs and hold almost twice the charge. That path is further explored at http://www.tekprosystems/zaurus/ , which has some other cool Zaurus mods, including blue paint and a keyboard light. However, please remember that 2300mah 1.2V x 4 = 2300mah 4.8V, not 9200mah 4.8V. It took me a while to realize that.

So, basically, you can get 6 hours for $45, or 2.3 hours for $19 (plus another 2.3 hours for every set of high-capacity NiMH AAs you buy)

I hope all this info helps, and I hope you haven\'t fallen asleep listening to my incessant ranting
