All solar power devices I found here around have 6V output but Z needs 5V.
Did anyone tried feed 6V to the Z? Is it dangerous?

Also on the back of SL-5500 is information that it needs 6.2W power supply but most solar packs offer ~1.5W only. Does it means that this will not works?

Thanks in advance,

In all likelihood those are 6v unregulated solar panels which can go up to 8-9volts... You would need to connect it to 4 nimh batteries with a diode in between and use the batteries to power the z, which charge when then the zaurus is not being used...

You can use a voltage regulator (it's a simple ciruit with ICI 7805 integrated or similar)
Try this url (isn't in english but....it's clear, I hope :-))

won't work... A) you need several voltages extra to allow for the voltage drop due to the regulator, and the current is simply not there to drive your Z...

but it might charge an external battery pack,?

I bought a solar charger kit last year from Maplin.

It uses 5 NiMH cells and has a regulated 5V USB socket to connect to the Zaurus.

It takes a "while" to charge but it does work quite well.

Unfortunately they don't seem to stock the same one any more but they do have some other kits.

Hope that helps.

I'll look up the model number when I get home tonight.

What is diode for?

Thanks all who answered wink.gif

It keeps the current from going back to the solar cells. Kinda like a check valve with water.
craigtyson
there are usualy "stock" circuits for this type of thing in the likes of prwactical electronics magazine. They can show you how to wire a charging circuit so that it doesnt damage the cells (unlikly with solar unless you live in death valley or start using mirrors to up the insolation (but watch the heat)) For the more adventurous out there Iv seen a design for a solar backpack here to keep your ipod et al going while you walk the wilds.....PS dont expect this to work in the lake district for obviouse reasons.... ie its always raining hmmm ipod water wheel backpack anyone???

I purchased an Aurora Solar Charger for my sl5600 about a year ago. When it was working it did charge the Z. However, a pin on the adapter broke and that had to be replaced before it would start working again. Fortunately, a friend was able to make the simple repair for me with the purchase of a new adapter from Radio Shack. There was some question of the pinouts but he resolved it (which is hot which is ground).

It's not fast, but it works.

I made a battpack for my Z some months ago but I did not put a diode between the Z and the Battpack... is it possible that my Z is charging the battpack when the power of the battpack is low?

You might try the solar powered lights from Everlite: http://www.newlite.com/

They have a 5V adapter that allows you to charge your Z (or other 5VDC thingie) from the battery
of the lamp, said battery being chargable with a solar panel. Pretty groovy.

Has anyone treid using the Aurora Solar Charger with their C1000 yet? Mine just arrivd. I'm going through the manual and I'll be darned if I can find the power specs for the unit. The plug on the Z is also an issue. I'm not at all sure it's wired the same as on the 5600.

After watiing so long for the C1000 I'm not going to rush into this.

On a related note: solar chargers that are meant to be beat upon are on (or coming on) the market from companies like Brunton and Pacific Outdoor Equipment. But they're not going tow work out-of-the box with the Z is my guess. While adapters may be available it's not clear to me if they are now. Many are building solar chargers that are meant to mate with devices that charge off USB (sigh... my Canon S70 does not; the Z does not). I hope adapters/battery packs become available for most of these. They're not cheap, but if you need serious in-the-field charging products like the 2 I just mentioned are the way to go it seems (I'm not knocking the Aurora, but it's probably much more product specific; and I know it's not quite as durable).
ltrm
Not sure how much this relates to the C1000 but I use the charger from my sl5500 with my c860. The plug is wired exactly the same.

Also, I have 2 usb chargers for my Z so you could charge from one of those new solar units.
kenknight
Yah, that is what it comes down too: plug wiring. I'm not sure if the C1000 plug is wired the same as the SL-5600. It probably is, but I'm not willing to chance it right now.

I think it is.... that is 8 think streamline sells the same powersupply for us c1ks as came with the 5600
ask them to be sure

I have a 5500 and 1000 and use the same Sharp charger for both. The unit that shipped with the 5500. Used it for both 110 and 220 volt countries with no issues to my 1000. Hope that answers your wiring question.

I have a solar charger by iSun. Damaged my 5500 by hooking it directly. The best way I've found is to charge a set of batteries and then plug my Zaurus into that pack. Check out the iSun with Battpak. The Battpak allows for up to 12 batteries and accepts a 12-volt car plug too. Gives you a lot of options. Using any car-to-USB charger gives you even more options for other devices.

I have an iSun solar power panel as well and also burned out my SL-5500 with it. I was correct in my decision to test it out on my cheaper SL-5500 before trying it with my more expensive C760. The problem is that if you hold the solar panels close to a light bulb, then the voltage of the device exceeds 6v/12v.
Snappy
New PV cells always come in at 110%~130% of their nominal ratings (of 6v or 12v). They degrade over the years and reach like 80~90% after like 5years or 10 for the higher end ones.

A 7805 voltage regulator is a good insurance to ensure only 5v dc goes into your device. smile.gif
qx773
The iSun solar panel has a switch for 6v and 12v output. I was using the 6v setting, and I believe that the voltage output by the device spiked to 19v when I put the solar panel close to a light bulb.

I wonder if this would work, since it charges a PSP.

Juz picked it up and charged til the red light went off. Current was ard 5.15-5.27 according to my cheapo multimeter. Havent really did solar charging and running the Zaurus at the same time so until i have a chance to test the multimeter charging under hot sun, Ill close the panel while in use and open it up to recharge when idle.

How long does it take to charge the Z's battery?

If u mean via solar, I haven really have time to do a test yet. Charging via cable seems ard the same as the Z.

This (Japanese) site sells a multi-purpose solar adaptor that it specifically states works with the Zaurus: http://www.violetta.com/japanese/hanbai/vausb01+cable.html

Just noticed something while using the solar battery to charge the c3000. There is a faint but shrill sound coming out of the Z which stops when thebattery is switch off or unplugged. Did anyone noticed something similar while using alternative power supplies?

found this it works for the psp it should work for the sl-cxxx series

Hello

Could someone of the lucky guys with the solar charger from Brando, clarify these two issues:
- is it bulky, or is it "OK" to carry around?
- is it possible to charge its internal battery with the normal Zaurus AC adapter?

Thanks.
jan

I guess, you mean "connect the Brando device to Z's 5VDC power jack and charge the Z". If not, that's my question now.

Plus: Voltage should be pretty stable (from battery). Has anyone measured this (batt full/empty, sun on/off wink.gif )? Found any risks to damage the Z? voltage/current peaks maybe?

How does the Z deal with low currents?

Aren't the solar panels very fragile?

edit: Is anything know about other solar charger for PSP or USB devices such "Solar EFX" and "Logic 3" available from ebay in europe.

i'm using C1000
anyone has suggestion for the solar charger?
henrysviper
I purchased one of these chargers from Brando workshop, and it operates nicely.
Actually the first charger brando sent me was defective, but he replaced it immediately, no questions asked.

The construction feels a little bit flaky, so the charger needs to be handled with care.

It is possible to use the Z's AC adapter to charge the internal battery. I've done it twice so far, it takes ~4 hours. You can even charge it while it charges the Z (although I wouldn't do that for extended periods of time, maybe the circuits get overloaded). It charges also under not-so-bright sunlight, but I haven't managed to charge it fully (i.e., the green led on the charger does not go off).

The current seems stable enough, in the sense that the charging light on the Z remains on, regardless of the brightness of the sunlight. Unfortunately I don't have a voltmeter. I'll try to borrow one, and I'll let you know.

I'll try to take more detailed measurements.

All in all, I am quite happy with it, and I carry it always with me. It was cheap, and it gets the job done.

I got the following mail from Brando:
QUOTE
It is around 700mA and 4.9v.
We cannot confirm it can work with SL-C860.

I had wished to get something more precise, like 5.00V +- 0.10V
Can someone comment on the 700mA. What if -- let's say -- flashing takes more? (Maybe we simply shouldn't risk it, charging under everyday conditions is good enough)

Nice to hear it works for you. How long did shipping take?
jan
I questioned someone from solarc the manufacturer (I assume) of E.Go and scotty solar chargers about Solar power for the Z. They recommend the E.Go Profesionial, either via USB (which I consider suboptimal as my Z doesn't have any standard USB socket) or via the "PDA adapter" (which I don't like because it gives you 5.3V). The problem is with the "patented" E.Go system, you can't select the voltage, the cable (or adapter as they call it) does. They claim it's very stable and can deal with high currents.

What do you think about the 5.3V? I won't risk it. The device is smart enough to provide ANY voltage, only their st*** cable/adapter business forces 5.3V upon the users.

Has anyone got a good idea how to connect from a USB plug to either the SharpIO/USB-Port on the Z or the power jack with. I mean, without cutting and soldering an USB cable and without relying on a huge adapter/cable cascade.

E.Go and scotty are available from electronics and outdoor (camping and alike) stores in Europe. The recommended item is usually 129 EUR. It can charge cellphones and casual (AA,AAA) accus, too. They use AA NiMH or Li-Ion internally for buffering. Charging from mains (world wide) is possible. While more expensive than brando or logic3, they seem to suit my needs best, if I could just select the voltage manually.

henrysviper, how's your Brando doing?

Is the 6K power plug and AC adaptor the same as the other models? (I hope so). From the back of my 6k I read:

5.0V--(DC), 5.4W (AC adaptor)
For use with AC adapter EA-70 (DC 5V, 2A)

One more question, does the 700mA means it takes ~ 3 x time to do the same job of the 2A AC adapter?

If we assume, the Z charger really uses 2A (which is quite a lot). Then yes. (It's even possible then that the battery won't get fully charged at all)

The tiny Japanese (100V) AC-Adpater output only 1A.

That's what I'm fear of. Anybody has the unit can share more experience on wether it's capable to fully charge the Z.
Ferret-Simpson
Hmmm, my 5600 says it has an input of 5v at 7.8w.

P=IV

I=P/V

Current needed to charge the Z at 5V input is 7.8/5 = (reaches for clie: bad at maths) =1.6A

With power loss through the Transformer, I'd say that's pretty reasonable. If it interests you, To run off the battery connector, the Zaurus itself takes 3.7volts at merely 0.92A
