Just make sure there is no CF or SD card in the slot, cant wait to try kexec'ing into another kernel

sorry about the thread jacking

Still waiting on kevlar to get here
Was cheap, so I'm patient with the shipping ^^

Any pics yet?

Just won an auction for a 3100.

Now to auction off my 5600.

a few possible bodies:
(and lots of questions!)


1) an exact replica of the original Zaurus body

I'm not *quite* sure what good it would be, though....
most of the damage that I've seen or heard of occurring on Zauruses
seems to be from physical/electrical shock to internal components.

A stronger case would be more resistant to cracks from wear or plastic fatigue,
but they seem to be fairly uncommon.
The Sharp cases seem to scratch and abrade- possibly kevlar or carbon fiber
would be harder, but I would imagine that more to be a function of
surface coating than structural material.

My real question would be: what added (if any) protection would a
replica replacement case give to the electronics or screen?

__________

2) a ruggedized replacement for the Zaurus body

possibly the same material, same construction, except with a little more room
to accomodate padding for shock absorption. If the case is built to withstand
impact (kevlar/carbon fiber obviously would be) and the internals can be
given room to move within a flexing case, then the Zaurus as a whole
should be more resistant to failure.

no warranty, obviously smile.gif

I'd be willing to pay slightly more for a slightly bulkier Zaurus with a slightly
greater hope of surviving catastrophe.

___________

3) water resistant case (SD, CF, audio, power, usb could have rubber seals)

again, it might help against accidental, temporary contact with water
but not necessarily be immersion-proof.

In custom configurations, some of the above ports might be sealed altogether.

I'm not sure if there is much of a market for the more advanced forms of
Zaurus re-casing; relative to what it would cost to build and sell them,
but I would definitely be interested in either a rugged, or a water-resistant
Zaurus case.

Also, a sealed screen protector (one which covers the entire upper panel, not just a corner of the LCD) but there we might be getting into materials that are outside
your field of interest smile.gif

Harder screen protection may also interfere with function of the digitizer, so it may not be practical in any event.

___________

4) other exotics

- replica Zaurus body with physical storage compartment (spare CF or SD cards?)
- replica Zaurus body with CF port mod to allow WiFi card to mount flush
with body.
- replica zaurus body modified to allow slightly deeper keyboard
+
replacement for Zaurus keys, with slightly higher definition

____________

That's *my* Wishlist, at any rate.

The more exotic, the more difficult to build, and the more expensive to buy. smile.gif

I'm still interested in the Type I, replica of Sharp's Zaurus body,
but if the original poster (or anyone else) can explain just what
a kevlar case would do for my C1000 as-is, I would probably be
more interested still.

thanks!

lol, people have some big ambitions. I'll answer some of your questions, mainly the ones I know the answers to. Unfortunately there are some things I don't know and I'm not one to make things up for the sake of spouting off on forums.

The materials are substantially more durable than the plastic casing of the zaurus. The casing Is relatively thin and of marginal quality. Not only does a composite/resin construction have higher tensile strength than plastic (by several orders of magnitude), but the epoxy coat is quite scratch resistant. What's more is, a coat or two of automotive clear-coat will allow you to simply rub off every day scratches with a light compound. Not to mention it looks great. (I WILL have some proto pics up when I have time to finish it off. I have the mold and the materials, all thats left is pressing it in and setting the epoxy. As I said I am a full time employee and a full time student, so time is at a premium)

As for the many different designs you mention, this is quite another story. I am producing the exact replica cases because I have a C-1000 on-hand that I casted molds for myself. Thus, I know exactly what it is, and how it should turn out. When you get into custom work, you are adding many many variables that often are lost in explanation. Without a very good set of diagrams or a CAM model it is very difficult for me to know just what you want. The most feesable mod at this point is a larger battery bay (perhaps by simply adding an extra milimeter or two to the entire bulk of the case) and external access to the internal CF drive. However, at this point I have not yet got a C-3k, so that will be on hold until I decide I need one.

If you have complex ideas on hand, you may consider creating your own! I have been doing composite for a while now, but there honestly isnt much to it. I do it as a hobby, in support of my other hobby, which is motorsport. If you do it yourself (or at least design your own mold), you can simply cast the case of your own Zaurus, then hand-carve any additional amenities or case modifications. This way you have exactly what you want. However, precision work with composites is difficult, and openings are generally cut after the epoxy has cured, making it a chore to finish the cut surfaces. The stock form of the clamshell is relatively simple, making it an ideal choice.

As for a case, I am prototyping a holster-style, formfitting case for the Z. It will not include a capacity to access the CF or any other external jack due to its compact nature. I am making it primarily for me, and in a limited production as with the case replacements. The case will probably have small holsters to hold your CF cards externally, and the case itself will be waterproof as I mentioned.

Once I have all my molds perfected and my technique refined I'll probably reach a capacity of about 10 units a month. This will depend on my availability. Also the availability of carbon has become a major concern. Aeronautical companies seem to be sucking up composites faster than factories can produce them. But, in either event, I forge ahead! Luckily, the limited supply of carbon I have been able to secure has been residual stock at a very reasonable price. The $100 price point was actually a bit high, and I'm hoping to produce for less. Again, there is little to no profit to me, and I will include a material invoice for all parts used in construction to ensure this. The only money I am making will go to pay for my paypal fees, taxes, post, etc.

If you have custom designs and can provide engineer-grade diagrams or CAD models, I can produce your custom design for a very modest premium. I will prioritize custom projects ahead of the normal cases. However, if you are in an excessive rush, or require very extravagant modifications, I would highly suggest investigating a CNC machined option in a material like aluminium, which lends itself well to such design. Composites are finnicky to work with when it comes to precision manufacture. This is a hobby, which for me is placed on one of the back burners. Although now I have a good idea of the level of interest to expect when I begin serial production.

Thanks for your replies so far and I will be more than happy to field any other questions you may think of. I'll have some pics of the raw materials and my ceramic molds shortly.

EDIT: Ah yes, as for screen protection:
You are correct in assuming that a britle screen protector should interfere with the touch sensitive membrane. In addition, I haven't had experience integrating a material such as glass or lexan into composites before. A resin shell is possible, but removing the touchscreen functionality from the Zaurus seems nonsensical. Also, the unit would not be able to close properly, and it would likely interfere with the exotic rolling hinge design of the clamshell. It is possible to completely redesign the case to close flush an include a hard screen protector, but then you must consider, what is to keep that surface too from being scratched! smile.gif

I think what is best is simply to replace the outer shell as I planned, which will provide added protection from every day abuse such as drops (I also failed to mention that the epoxy coat provides a limited degree of shock resistance), scratches, spills, babies, medievil crossbowmen, spears, mongolian hordes, and zombie pedestrians, while making a clean, good looking Zaurus.

If you are obsessed with a modified, ultra tough zaururs, there are plenty of precision machine shops online who can laser cut your CAD model for very, very reasonable prices. The primary appeal of this case should be its good looks with the fortunate side effect of being tough!

My *dream list* would be a bit of a larger case that would:
-have a non-powered hub wired to your internal USB host so that you could have normal modern usb ports on the side of your zaurus for mouse and keyboard.
-have a large PSP battery inside to extent the battery life of the zaurus 2 or 3 times
-space to have a USB WiFi, BT and Ethernet device stuffed in there and then an ethernet port on the side of the case.

A docking station that provides what I've mentioned above would be nice too.

Sorry... just dreaming.

Sorry Maytagman for hijacking you thread... but Antikx I never thought about making a Docking station for my Z... but that is a very good idea... but I would prolly put in a powered usb hub, wireless(usb of course) and I know there is something esle that I would like but I cant think of it... I think I'm goin to research this...

But Hey Maytagman still keep us up to date with any updates.... Also did you recieve the Kevlar yet?

Thank you, maytagman, for a clear and succinct response to my not-so-clear or succinct query!

Earlier in the thread you asked something along the lines of "what do you people want?" so, my last post was a shopping list of all the things I'd like to see in a new Zaurus enclosure. smile.gif

I might have complex ideas, but not well fleshed out ideas, or much/any experience in materials forming.

This being an external protective case for a Zaurus to fit into?
Or a replacement Zaurus body with these features?
Either one sounds *interesting*.

$100 is more than I'd like to pay, but it definitely sounds reasonable.
I'd expect to pay at least that or more, for comparable effort.

Do you have ideas or thoughts, on how to integrate a soft (but durable?)
screen cover, either removeable, or integrated into the case?
I've had mixed, but not really great results with most of the
stick-on screen protectors I've used so far.
I'd be willing to give up a *little* precision of mousing,
for a little more durability. I'm not sure if that scales well at all.

Yeah. It'd be nice to know how much more you actually get, with a cloned
replica case in the composite material.

Obsessed with the concept, yes.
"Very reasonable" is still probably a few orders of magnitude more than I'm interested in spending.

Truly ubiquitous computing - a handheld for all seasons, and all environments
is something that interests me rather a bit; though I honestly don't have any
specific application (or funding, or time) for such research.

so,
mark me down for at least (1) replica body, of one sort or another,
if you ever get them into production.

and many thanks smile.gif

Ya. I agree. If I was making a docking station I would put in a powered USB hub too.

i'm interested in the case as well. I don't think a desktop docking station is really necesary. A case with more built in power, usb, etc would be cool though
