I've had the idea about rolling my own Linux powered PDA for some time, but I've been busy with another project of mine. So, I haven't posted about this idea, but recently Da_Blitz posted:

QUOTE(Da_Blitz)
the iMX3 is a custom PDA idea as the 2700G chip is VERY hard to get. dont want to hijack this thread anymore so if you want more info then contact me direct or make another post


Definately looking for some more info on that!

Here's some interesting ideas to get the thread started:

GumStix ( www.gumstix.com www.gumstix.org ): Very small, proprietary, stackable modules. Very hobbyist friendly, but current models are still based around the Intel PXA255.

Colibri Module : PXA270 with most of the needed chips built in, and connections for most of the rest, in a formfactor of a DDR SODIMM. Moderately hobbyist friendly, with boards only 119Euros for the 520MHz version, but with a fixed handling fee for Hardware of 100 EUR and shipping of 45 EUR. You'll want to order more than one to be price effective with this supplier.

CM-X270 Computer-On-Module: I stubbled on to this site last night. No idea about this supplier's ablity to handle hobbyists, or even the cost of the module. However, you can configure a pretty impressive COM on that page. Up to PXA270 520Mhz, 128MB of RAM, Intel 2700G with 8MB of its own RAM, audio codec, and 512 MB of NAND flash!


Take a look at the Google Ads when you do a search for 'Arm development board', as quite a few Ads hit the mark for what we would want, if they could be had cheap, and single unit quanties (which most aren't sad.gif ).

The omap3 chips are also nice in that regard, with integrated graphics and all.
Da_Blitz
I have 30+ links to every manufacturer of xscale boards i could find that came in handy on nuemros occasions

one of the reasons i mention it is that i am about to take a couple of months off and am lookinf for a hobby or somthing to do in that time.

the reason i mention the iMX.3 is that you can actually order them from the manufacturer and they are arm11 chips which support multiprocessor i highly doubt this chip still has the multiprocessor stuff in it, i never did like Ti's omap due to reports of bad performance when watching video when compared clock to clock against a pxa250 (no optimisations for ethier) however the intergrated media stuff may be worth a look

atm here is why i like the iMX.3
USB 1 12mbps, 2 480mbps (one of the high speed is OTG compatible) wink.gif
DDR SDRAM @ 266MHz
Graphics acceleration (instructions and an extra core as far as i can tell)
Random number gererator in hardware
2x SD CARD
PCMCIA
camera interface (with auto color space conversion)
A floating point coprocessor smile.gif
ATA interface (we could have a Shell like the 3800 compaqs with a HD in it)

so any one want to get together and discuss this in detail i see it costing as much as a c1000 with no profit at our end, i know a company who makes PCB's and populates it for you that has competitive prices so we could just give people the link and they ship it direct. case would have to be purchased from somewhere else but i was hoping we could get a company who could make a cxxxx/XDA4 type case AND a slider type case (like the kjam) that you just put the board in and screw up

minimum feature set i had planned consisted of gsm radio bluetooth usb host SD card 64MB DDR ram.
if i can add it 128/256MB of ram, wifi. CF (should be a no brainer but i want to keep it small) VGA out, a camera, gps (i think an external bluetooth unit is better)
i dought all the last stuff will get in however i am sure that at least one or two of those would be included

Hot DAMN! tongue.gif

2700G, 128MB+ RAM, VGA out and hi-speed USB2 OTG? If you could somehow get this into a clamshell of a similar size to the Z then my dreams would have come true!

What are you doing about the display though? To really make it perfect I'd want at least 800x480 so I'd be able to plug in a USB DVD drive and watch films on it without using an external monitor.

Personally, I'm not really bothered about SD or PCMCIA but CF is a must-have for me in a PDA.
Ragnorok
- Thanks for the link, koen. Nice feature set on that guy.
- Could you put a link or two out for those boards, Da_Blitz? I'd like to peruse what you consider the most likely candidates for a project like this.
- I'd like to see at least 128MB RAM, at least one CF (prefer two, or more [!]), at least one SD, at least 800x600 touch-sensative display, Psion 5MX-like "full travel" keyboard, at least one USB host port (2.0 nice but 1.1 good enough), and clamshell form factor. Built-in BT/WiFi/HDD would be nice but not strictly required if two CF are present. Video acceleration appears to be part of the package, which is attractive.
- VGA out, camera, and GPS are ginger bread as far as I'm concerned; I don't need them in a PDA and would prefer the inclusion of items above. If I really wanted to go off the deep end I'd include a 100Mbit Ethernet port waaayy before I'd include any one of these three. I never have liked the Rube Goldbergian USB/faux NIC thing that the Z uses ... better to have the real McCoy imho...
zmiq2
The most problematic I think it's getting a keyboard that fits in a clamshell design. Does any keyboard already exists that would fit ?

If anyone designs this device, I'm first in row to get/build it !
danboid
I'd definately want separate mic and headphone sockets on this as it sounds like a great portable media workstation in the making. An ethernet port would be cool, definately.

How much would a ~5" 800x480 OLED display cost for this?

What would be its best bet for power source/ battery?
Tom61
Getting a decent resolution(640x480 or greater) good screen (TFT active matrix or better) in a size suited to a handheld and for a good price is the main problem I've not been able to solve. I can find cheap screens, but they are lower resolution or STN. I have not even found a good source for 640x480 or greater and 5" or smaller screens, save for some PDA repair places, which charge around $200 for a X50v display (640x480 3.7" TFT).

As for the battery, my vote is to find a popular device, with a decent capacity removable Li-Ion battery, and tailor the custom PDA to that battery. That'd give us a good immediate supply of batteries, and likely a decent replacement lifetime.

Thumbboard is trivial. You can pretty much grab any thumbkeyboard you like that hooks to a PDA, take it out of it's case, wire it to a serial port, figure out it's simple protocol (like is done for larger PDA keyboards connected to the Z port), and put it in the clamshell's case. If you want something with less software configuring time, you could grab this PlayStation2 mini keyboard and hook it up to USB, though it isn't the greatest thumbkeyboard. Also, if you have a keyboard that you really like (like the aforementioned Psion 5MX one), you can rip it open, map out its matrix and wire it up to GPIOs or an existing compatable keyboard controller, pending on your coding level. GPIO would require a fair bit of software dev'ing, but adapting an existing keyboard controller would only require creating a new keymap.
Ragnorok
- As it happens I have both a Psion 5 & a 5mx, which are nearly identical except for color and innards. I suppose replacing the guts in one of those would be out of the question?
Da_Blitz
Ok i like this i am not getting the usual "i want 512MB of mem and a 32310238GB drive (even if i say it as well)

what i intend to do is produce a PCB, and mabey a keyboard PCB. i want to leave the cases to some one else to make so you can have a clam shell or perhaps a slider like the k-jam. if i find a form factor like the psion i might make the board fit in the old shell but getting the hardware to work is someone elses responsability, in fact i will give you the design so you can change the board shape and auto-route it yourself, same hardware diffrent shape

what i am looking for is anyone else who wants to help develop the hardware, if you know anyone plese tell them

my minimum at the moment is bluetooth, SD, GSM (Phone), 128MB of mem and USB host, i do plan to make it expandable so design it to take more ram but not solder it on for those who want to expand the design (chip supports 256MB max) there will probelly only be one CF slot as that is all this device supports and it will most likly be internal but depending on the case you will probelly be able to externally acsess it (ie i will try and put it near the edge but dont expect miricles if i cant) might even consider upping it to a full pcmcia slot so the user can chose

i would like to get 802.11N but there is no standard so G it is if its added and Wi Max (there are chips but no drivers) and VGA out as well, cammera would be nice as well but i think that other things with higher priorites will replace it

i intend it to be very mobile phone centric (hence the GSM and bluetooth) or as a mobile phone extended c3k

as such i need input on not only what you want to see but how you would use it, how much you are willing to pay i am looking at between c1k and c3200 price at no profit so keep that in mind

for the bootloader i was thinking a 16MB partion thats RO in hardware and CANNOT be upgraded to hold a kerenel that can kexec another kernel but have utils to do diagnostic and repair, doing it this way means there is NO way you can brick the device as there is always the inital firmware

for screens you could salvage your Z's screen as i said i will build the hardware, not design the entire thing i will try and make it flexible enogh to acamidate a bit of varince in hardware

i am also thinking of selling the design off to any company that is intrested on the basis that we can buy direct from them at discounted prices. i belive this would be an advatage for us and them but i would say1 in 50 chances at the moment

and now some links (including thin terminals and Xlinx FPGA's whigh i would like to have one of on board)

This is getting pretty exciting ... smile.gif

My needs are simpler ...

Based on my existing Akita

% Screen to be transflective > 4.5"
+ wifi 802.11b/g
+ gsm/gprs (optional)

As it is, Akita is serving me well, esp after I got wifi cf working. A transflective screen should help improve batt power as strong sunlight is available 365days where I am. biggrin.gif Built in wifi should mean better antenna and possibly better power management.

GSM/GPRS is optional but is on a Want basis. smile.gif

"Ok i like this i am not getting the usual "i want 512MB of mem and a 32310238GB drive (even if i say it as well)"

If you have a 32 petabyte drive, you might as well go for a terrabyte of RAM. tongue.gif

"what i am looking for is anyone else who wants to help develop the hardware, if you know anyone plese tell them"

I'll check on some other forums. Anything in particular you need help with?

"my minimum at the moment is bluetooth, SD, GSM (Phone), 128MB of mem and USB host, i do plan to make it expandable so design it to take more ram but not solder it on for those who want to expand the design (chip supports 256MB max) there will probelly only be one CF slot as that is all this device supports and it will most likly be internal but depending on the case you will probelly be able to externally acsess it (ie i will try and put it near the edge but dont expect miricles if i cant) might even consider upping it to a full pcmcia slot so the user can chose"

Looks good! If you go the CF/PCMCIA route, it might be easiest to have headers one behind the other, and then have the company that populates the board put only one connector on.

"i would like to get 802.11N but there is no standard so G it is if its added and Wi Max (there are chips but no drivers) and VGA out as well, cammera would be nice as well but i think that other things with higher priorites will replace it"

My vote is to have at least solder points for everything the chip supports.

"as such i need input on not only what you want to see but how you would use it, how much you are willing to pay i am looking at between c1k and c3200 price at no profit so keep that in mind"

Not sure if I'm in on this or not, as I've not been so keen on paying a premium for an open platform in the past, although this is certainly an interesting project

"for the bootloader i was thinking a 16MB partion thats RO in hardware and CANNOT be upgraded to hold a kerenel that can kexec another kernel but have utils to do diagnostic and repair, doing it this way means there is NO way you can brick the device as there is always the inital firmware"

I've always been fond of this style of Rom handling, save for the habit of developers not worrying about stability/flashing of the secondary rom.

"for screens you could salvage your Z's screen as i said i will build the hardware, not design the entire thing i will try and make it flexible enogh to acamidate a bit of varince in hardware"

:/ Screens are a pain to get ahold of cheaply, and pulling one out of a $400+ PDA doesn't sound that great.

"and now some links (including thin terminals and Xlinx FPGA's whigh i would like to have one of on board)"

I definately will have to look through these. Interesting diversity for sure... FPGAs certainly are interesting, but I'm not sure with a chip as loaded with features as the iMX3 really needs one.

BTW, does anyone know why using [quote] tags by themselves don't work?
Ferret-Simpson
Hmm. . If I remember my XDA's correctly, doesn't a GSM/GPRS phone have basically a second GSM processor, which is accessed either directly, (By taking over the hardware) Or indirectly (From within the other processor)? But still definately a fully functional second processor.

GPRS is a MUST, if 3g isn't a possibility. I think internal wifi is important too, even if it just goes out to an empty socket that can be connected to an external aerial port. If we only have one CF/PCMCIA port available, better get as much onboard as we can.

http://www.dicoll.co.uk/lcddisplays&touchscreensover.htm - This site seems to deal with what appears to be a 5" VGA screen with touch panel, didn't mail them though for prices.

Hmm, Keyboards do seem hard to find. . . :/

If we can get access to the equipment to make a motherboard for a "Slot in module" shouldn't we be scratchbuilding completely? And shouldn't we be Getting production numbers made anyway? XP

So, Who wants to set up an OpenPDA corp?

Considering the slowly diminishing interest in the Zaurus outside of Geeks and University Computing students, and the complete lack of open embedded hardware bar the GP2X - |I think it's important that some form of Open Embedded hardware is developed and produced, even if it's Motherboard Only - Although it would seriously improve the number of sales if a ready-made system could be built. . . Just think! You could even Laser-Engrave Tux into the top of the rotating screen!

If someone makes one of these successfully, then I'll even try to make some companion ubiquitous hardware. XP - - (Colour linux watch, based on the same TFT panel from the 6100 or 6230? XP)
Ferret-Simpson
Sod. Forgot my most important thought: The power.

Camcorder batteries! They mostly get modified for use in Zauri anyway, so for our "Open Source Zaurus" Why not use them directly?
stampsm
count me in. i have been looking for a project to work on. smile.gif i also got a few nice toys like a ulink jtag debugger and a few dev boards for procesors like aduc7026 lpc2138 lpc2119, ect. ( i love ebay ). the dev boards i have are mostly for low end arm processors though, so i am thinking of getting a dev board for some higher end arm processors, but i am a poor college student so my budget is not to high. i have tried a little at designing pcb but i have never got the hang of it. you can kind of say i am a jack of all trades. smile.gif
Da_Blitz
[qoute] Looks good! If you go the CF/PCMCIA route, it might be easiest to have headers one behind the other, and then have the company that populates the board put only one connector on.[/qoute]

yeah thats what i am thinking of doing but if board real estate is at a premime i might chose the pcmcia and let you use a pcmcia to cf adaptor

for battries as i said i am only making the board however lookinng at all of this it might be a good idea to prouce one design that fits in the exsisting cxx00 case as you can buy the case seperatly and that means you can use Z battries

you are right about the mobile phone processors, we will most likly talk to it ove a serial port rather than have it built into the chip or mem mapped, this means nice and simple At commands to control the phone and also means we dont have to write software

the gsm is more of a minimum spec however we do have a problem in that each contry uses a diffrent system, i might point out that i also live in australia so its in my best intrestes to make it compatible with whatever we are using here that said it shouldnt be too hard to adapt it or even have plugin cards so you can swap radios (this would also make the board desin simpler)

probelly wont have solder points for everything, mabey a couple of things and the mem bus (thats already 98% of what you need) but i think it will be more like: i want this hardware so i "port" it to the design, reroute (equivelent in software terms would be compile) the board and then get it manufoctured and populateed by a company who returns your design to you in about 3 weeks that way i can jam pack the design

note that doing it that way is really for new hardware, if you want for eg to add bluetooth then there will be a solder point for it only the more exotic stuff will be missing

actually i was thinking sharp would be a potential buyer of the board and would help drive down costs or we sell the design to them under a diffrent licsence (as i want to do a GPL type open hardware design)

I have found a place that sells Xscale chips in small quantities but the iWX3 is ALOT cheaper and has video acceleration built in as well as DDR ram support and a floating point unit so it would take alot for me to switch back to that chip

the chip is also used in the toshiba gigabeat in case any one was intrested about the sutability of this chip

the one thing i forgot to mention is that i also want the ability to turn this into a thin client so on board ethernet might happen or might be limited to the pcmcia slot but it does garentee usb slots and VGA out wink.gif

this chip also hhas the same problems as the intel in that the pcmcia and cf intreface are shared weth main mem so i am looking into alternatves for storage eg huge flash capacities 2GB max can be done with one chip thanks to samsung and also support for ATA drives (laptop HD anyone) with the ata stuff you may be able ta have a mem only CF slot and a IO capable one, the advatage being that the mem only one will not cause a decrese in performance as it has its own mem bus

touchscreen dosent affect me as i use the console but of course i will add support for it

i might add a loptop ram header so that people can make daghter cards and plug them in, and because it will have the data bus signals it would be posible to add more ram (of course you would have to make a board to take the ram, you cant just put laptom mem in it)

will try for transreflective if i can but i am not making anything but the mobo, i would like others to help with this espesially if you have design skills or if you know where we should look as for electrical people if you know any and they are intrested get them to email me at jaycoles (a) yahoo.com and tell them to include the word ilnux in there message (to bypass my spam filtering

with the price i fugire that you would want more funcitionality at the same price point but if you dont want those parts then i will tell the manufacturer to not solder them on the board smile.gif

the fpga is there for glue logic rather than use an asic to basically cut my dev costs, they chew throgh power so i would probelly use a cpld instead but might have a fpga avalible as a add in card for devs and hobbiests (eg software defined radio for fm reciver or ham radio)

Ram Max is 256MB so thats plenty, i think that can be done with 4 chips as well so net much real estate for BGA parts

i would really like to see an open hardwae company, at the moment i am working on a project for gensis who make PPC boards and are VERY linux friendly to the point where they are writing XGI graghics card drivers with the 2D open source and the 3D closed because of NDA however the will compile it if you need it and will show you if you sign a NDA (i know its a pain but its not bad) the other thing thats nice is the hardware they have avalible online to play with and the hardware giveaways they have (they are the reason i found this chip)
Da_Blitz
WOW thats long

if i was designing a pda here would be my basic design plan

-the case design would be a real hard decision since there are fans of both clamshell and regular pda design. if it was my decision i would most likely go for the zaurus CXXXX clamshell with tablet folding capability because it seems to be more versitile and easier to integrate a built in keyboard

-ARM processor at least 400 mhz preferably 500-600 range or at least capable or overclocking to that range

-lcd display of at least 320x240 but strongly suggest 640x480 size (try to avoid odd sizes such as 800x480 since that would most likely cost more since there would be less of a demand in the market for that size of display.) touch screen of could would be needed. the size i would look for would be in the 3.5" to slightly over 4" range

-external memory slot in the form of at least 1 CF possibly 2 CF if the chosen processor already has 2 ide channels built in. add a sd in at least mmc 1 bit mode or better yet 4 bit mode since it gives cheap memory expansion in a small size for very little I/O cost

-when it comes to the modern connectivity way of life i would strongly urge to add wireless capabilty with preferably bluetooth and wifi. the wifi capabilty may be best to keep with a CF card if two CF slots are availible. the cost is quite low for the user to add and it gives the option to add a cf wifi card with wardriving features such as external antenna. the bluetooth is an option that should be added to the board even if it is not populated so the user has the option to add it latter or have more than one hardware model so those who do not use bluetooth dont have to pay the extra cost.

-when it comes to ram 64MB is the bare minimun and 128MB is what i would suggest. better yet some memory ic chips have 64MB and 128MB versions in the same footprint so you can have one design with a possibility of two different memory options. better yet if you could find an affordable memory ic with 64, 128, 192, or even 256MB options in the same footprint that would be the best choice.

-when you look at most rom distrobutions 96mb is the lowest i would put in a newer pda since that can easily be filled up. better yet is to use a 128, 192, or 256MB footprint compatable ic in the design like the ram to give more flexibility.

-an integrated keyboard is a must especially in a clamshell design

-built in headset jack and built in microphone/speaker is a must

-USB on the go is a must and since alot of usb devices need a good amount of power i would recomment an optionable external battery pack be designed to be able to clip onto the bottom the the pda to allow longer battery life.

-i can see IR ports being taken over by bluetooth, but i would still include it. as a hardware hacking freindly feature i would design the ir module to be disconnectable and allow a plug to be exposed that could have something else plugged in.

-follow the "if you dont use it dont cover it up" idea. basically if you dont use a pin or line pull it out to a contact pad and document it.

-all most forgot this one. you need a serial port for linux use. biggrin.gif

-jtag port pulled out in an easy to use way (dont nessesarly add a header pin to plug it in, but at least have the possibility to add one

-ohh and a gift for the hardware hackers. smile.gif a cpld/fpga on board with all or most unused or even some used lines run through it for customization.




the hardest things to deal with for this in my opinion would be the display at a reasonable cost.

my case design would most likely be a clamshell with a CF slot on either side and the SD, IR, and usb connectors in the front. and the audio and docking connectors in the back. on the bottom i would have clips for holding an extra battery pack and also expansion plug on the bottom like some laptops have for extra accessories such as a docking station like stuff

i would like to add that i like the idea of the freescale i.mx processors. they make really nice stuff at freescale and are quite liberal with samples for working with (can you say free cpu's to build prototypes with ) the i.MX31 processor has a nice 3d graphics accelerator built right in with OPENGL ES support including drivers and libraries.

And good choice on your Zaurus! POODLE LUV! wub.gif

If we've got an open board REFERENCE design, then any GPL based company (Hardware Fedora/Mandriva anyone?) can modify that as long as they give the schematics free. XD

GPL hardware seems to be a more profitable thing than GPL software, so I can see a company based on it doing very well, since there aren't many people who are willing to scratchbuild a system.

I think building a retrofit board for a Zaurus isn't the best idea, because the zaurus parts, while available are quite rare in some places, inclusing the UK. It might also be cheaper to have someone press Aluminium cases for example, and there's still the point of a funky logo. On which note, this concept needs a name and logo! If you're doing motherboards, I can see a collaboration with a couple of other community members to make a full PDA.

There are some very small self-contained serial IRDA components out there, so I can see it being feasible to build a hotpluggable connector for IRDA which can be unplugged to leave a Serial/JTAG connector (Why the hell would you need Serial and IRDA simultaneously anyway? RHETORICAL.)]

WOAH! 530mhz? Sweet!

Does a microdrive have a Standard ATA interface? Apparently We can expect 20GB drives either this year or in 2007, so If it's possiblee to include a Microdrive compatible interface that's great. ^^

2 MMC/SD ports: If we don't take advantage of that we're insane. Anyone know a place that does 2-port PCB-mount SD sockets? Either that or it would be worth the space having them parallel. Internal Storage, plus 2x2gb SD. Anyone know if they're SDIO capable?

The disadvantage of PCMCIA is it's mooch bigger. Agreed, it would be nice to be able to plug in a 24/96 12 port digital rec. . . I VOTE PCMCIA!!!! O.O |NOSEBLEED FROM EXCITEMENT|

A Quad band phone will work anywhere. If we can get a Quad Band GSM/GPRS processor onboard, that gives everyone worldwide access. W-CDMA is nice, but it's expensive and not well supported. If we're really desperate, we can always put in a Vodafone PCMCIA card.

But yes. The i.Mx31 is looking to be a pretty good chip!

One final note: A few people have mentioned Cameras. . . If we're making a universal/Spitz clamshell design, I don't think we could go wrong with a camera mounted next to the screen (In landscape), below it (in portrait) since the i.Mx has an inbuilt CMOS/CCD interface. That would allow VoIP, as well as limited photography. The only other design I can suggest for it would be a rotating camera on the edge of the screen, with a 180' swivel.

This would allow camera usage for both conferencing and picture taking. It's either that or USB webcam!

I'm also with the note on TFT panels. 800x480 is just silly. We'll make it harder to get parts, increase the drain on system power and processing capability, for a fairly minimal gain. It's much more important to have a simple useable screen, similar to that of the CXXXX series Zauri, which is perfectly good! XP Besides, if there's going to be some form of External monitor connection, There's not really alot of point!

Finally, I vote for the name "PocketPenguin."
Ferret-Simpson
Forgetting things AGAIN:

Dan, Why the HELL do you need a 800x480 to watch DVD's?

The best quality DVD's available are 640x480 anyway.

Maybe when BD is out. . . But I doubt we're going to be hooking BluRay up to a Zaurus-Type anytime soon. . . Maybe December time?

Yeah a camera would be nice but i would put it on my first to be droped list if i run out of space the nice thing about it is the image processing unit that fixes up the image the os even sees it (eg color space conversion) this means higher framerates and lower cpu usage

seems audio is a big thing so definattly 1 headphone and 1 microphone on seperate jacks what i was wondering is for the video out, do we want VGA a tv connection HDMI (nice small plug there) and what type of sound capabilities eg 5.1 (ok i am dreaming but keep in mind that i can chuck that in if you want a portable media center) as for 24/96 thats why i boght an audigy usb sound card, but you need usb2.0 to use all 8 channels at that setting (whigch the cxx00 dont)

i was thinking about dvb-t but as we have usb2.0 it dosent matter about bandwidth (see OZ fourm for original post)

i want a list of everything thats posible so i can put up another list that i have gone throgh so people can vote on what they want, keeping in mind i will have final say scince i only plan to produce one then make the plans avalible

it has support for 4mbit irda and i thoght i would throw in CIR to get a longer range so you can use it as a remote

ill just clarify somthing because many people seem to be ignoring it, this is a project to build a mother board, i am not doing cases or LCD screens however i may do a keyboard design, i fuguire someone else is better connected than me in that area and could help out. it also means multiple case options wink.gif i would like to see the sidways slider format with backlit keys in carbon fiber with a laser etched logo, plus i would love to see the return of the compaq backpack idea and am willing to add an IO header for that (mabey instead of the addin card)

quick price guide
Xscale chips (any of them) $100 or more
iMX3 $20
guess theres no competeion here, both are for small quantity prices and as i said, i have now found sources for both, the free cpu's they have have no video acceleration however the chip is so cheap i dont care

good point about JTAG, i would list that as critical scince thats how i would want to loda the inital firmware, and a serial port is a definit, would you like TTL levels (5v needs external converter) or rs232 levels (12v inverted)

i had an ide about the secure boot, get it to boot into a kexec capable kernel and then have that verify the kernel it is about to run using gpg and a public key, easy to implement and means easy security (of course you dont have to use this feature) best bit is if you burn the public key into the ROM itself to prevent tampering. i think this will be for the hardcore only but it fits well with the camera and mabey a finger print reader to do iris and finger print recignition

names are a good start as they give it a "feeling" or spirit, unless anyone thinks of anything better i am offically calling this the Pocket Penguin Project or PPP wink.gif

SD thats a good idea i only really planned for 1 but i could add 2, they are SDIO capable if i rebebr corectly but we need drivers and a generic sdio stack, i belive the stack is posible to write without offical documentation and the wifi drivers could also be eginered in time, but we could shortcut this and buy an exsisting stack (about $5 per device if i remeber correctly) but apart from the bluetooth card i dont see the point and scince bluetooth is onboard there is no point (i might clarify i had a sandik sdio wifi card and several CF wifi cards, the CF ones get 4x the range and alot more speed (mainly due to the better signal) i also had that card degrade to the point where i could not use it anymore (refused to be recignised) and this was 5 days after it was out of its 1 mont warantey)

should we set up an IRC channel for a meeting some time it would be a good idea to flesh out these ideas some more

yep microdrives are ATA compatible
Ferret-Simpson
Never used IRC. I think sticking to Forum is better, just for us reets that wouldn't have a clue.

I've been sketching out a generic case design based on the clamshells, just a weeny bit bigger. (I know you're not looking at a case, but to we have everything in the same thread would make sense until some bright spark builds a website. - NOT ME! My server won't boot.)

In my design (Pointy corners, all the hallmarks of an Alpha) I worked around a base design of 126x14x65 (NOT including Screen or hinge - I didn't want to estimate a depth on that) which managed to squeeze 2xSD 2xUSB IRDA, HDMI, Dual 3.5 audio and an Aerial socket for a wifi antennaon the backplate, with the PCMCIA socket running alon the bottom of the case and opening up on the right hand side (In landscape mode) so it would poke out the top in portrait.

I did a basic design for the top of a screen panel, with stereo speakers, (The kind that look like (##) as seen on the Uni)

as well as a rotating camera, on the right hand side. based on a Samsung camera on my Mum's mobile, which seemed to work.

My design left the front panel of the Base unit (Landscape) free for say. . a scroll wheel, and maybe a power or docking connector - Someone mentioned a Powered notebook HDD "Backpack"? which could have it's connector behind a panel on the front.

Only thing I did find, was that with the PCMCIA card there wasn't much room for a battery. . . Since the motherboard will take up the better part of the case, It might be better to lose the PCMCIA in place of a CFIO? A PCMCIA card, socket, and a 750mAh nokia battery took up the whole of the bottom of the case, up to a third of it's depth. . . I don't think we could fit it all in a reasonably sized PDA, and the space on the motherboard for the socket would be better used for onboard Wifi and Bluetooth chips, and all internal storage being onboard flash - A microdrive is quite big after all in a device this size. besides, after 1xCFIO and 2xSDIO. . How much more storage could you want? Even if you're using the CF for something strange, like a 3g card, a 56k modem, or a 10/100 - There's still two SD sockets. for up to 4/8 gb storage.

My refined specs (IMHO) that I looked at after running a design up are:

iMx31 530mhz/133mhz
128/256mb DDR266
4.5" TFT fitted nicely, 5" is getting a bit too large, although if it's all we can get, it can be done.
Separate 3.5mm Line in/Lineout (Or mic, depending)
2xSDIO
1xCFIO
1xHDMI
1xIRDA
2xUSB480
1xCamera - We'll have space in the screen panel for a rotating camera, and it'd be a waste of a good chip function not to include one. ROTATING, to use as Camera and VOIP.
1xEXT wifi Aerial socket. - If people prefer internal that's fine, but several people have added external sockets to their PDA's or cards, maybe a simple folding aerial like on most Routers and Desktops would be worth it? Or maybe just put an internal and a socket?
640x480 Res
NAND Flash - As much as we can fit in there really, I can't see how we can get a CF or MD on a PDa size mobo with Phone, Ext-CF, SDIO
Quad-band GSM/GPRS phone, so we can all use it. ^^
STD mini-Sim socket, as used on every mobile for 12 years
Camcorder-battery Larger than 1500mAh, or if vertical space gets to be a premium, maybe two smaller Phone-types?

APM: Alot of this stuff is going to be big on power drain, so it has to be possible to Software-Power down at least the Wifi, Camera and Bluetooth, and Possibly the phone, too.

We've got a generic geek who can make what are only just unreasonable demands (Me.)
A motherboard Guy (All hail Blitz!)
A name (Of unknown popularity)

What we need, is someone who can seriously look at a case design, and maybe somewhere to manufacture them? When I was making my rough sketch design, I was thinking a ?pressed? Stainless steel or Aluminium shell, about the thickness of the average credit/debit card? (2/3mm)

Just so you know, I based my motherboard size expectation on an ipaq 3950 motherboard that's lying on my desk, (PXA250) and a DragonballVZ-33 from a clie (Which is TINY! o.O)

Since I'm guessing your average Moto-based board will be slightly smaller than say the iPaq board, because of the greater number of integrated components. - My Stacked SDIO idea came from a multilayer board with one conn. on each side.
Da_Blitz
Ok got it dropping the pcmcia and making it a backpack

for the board i was thinking mabey even 2 boards staoked ontop of eachother as this would then be about the higet of some of the connectors and gives us huge amounts of real estate this would allow the 2 SD cards above each other, also i hope you estimated full size usb ports as i hate adaptors, plus if you put it on the back it would be great for a docking station

the layout as i see it is CF on one of the shorter sides (left most likly), headphones on the other (headphone and microphone/headphone so 2 or 4 channel depending on settings) USB along the back (at least 1 usb mini socket, if there is room 2 full sized sockets), irda on the back (makes more sense there) and hdmi on the back (for the docking station), antenna will be female and an the back so it sits flush and you can use an adaptor, backpack connector ethier into the CF slot (CF and pcmcia are just diffrent sockets and current draw) or a connector next to the headphone jack

check out the cassiopia for form factor, i have one here and it has a full pcmcia slot and isnt that bad apart from bieng a bit big, i think we might end up with several diffrent form factors at the end of this for a couple of reasons, i would like to see cheap arm "blades" as well, ethernet, 8MB of ROM and 256MB of ram and nothing else so that i can have a native compiling cluster to work with and considering the price of the chips and how integrated they are it would be about half the size of a credit card and would be handy for inital dev work (a cheap platform to test drivers, for devs)

i would drop the rotating screen but am open to leave it in (i never use it or the touch screen) leaving it out simplifies alot of things mechanically and electrily

thats what i imagine anyway, mini sim is a must, wonder if we can use its security features somehow

good point abot the antenna, i agree tat that is a must and would be required if we use a metal case

we need a thick metal case in my opinion as i dent them fairly easily' if its metal i could also use it as a heat sink which is a plus (not sure how hot they get need to check power consumption)

i havent looked at power consumption yet but i would like to stay at around the 2Ah mark as it is a good size and fits nicly with the double boards

it would be intresting to take this design and make it into a long life laptop as well as it has the media capabilities, by keeping it flexible we could do this and these cpu's use 1/10th the power of a laptop (based off xscale power consumption)

i hope to have a website up soon for several resons so that should not be a problem

apm is a must hoever i think that dynamic power gating and freq scaling are very important as well
Ferret-Simpson
I actually think the rotating screen is important, because everybody else DOES use it. XP

Actually, I'd say IRDA should be with Audio at right.

Stacked board makes sense, because it means we can make the overall area covered by the board smaller: This makes fitting in the battery easier, because it means we can use the full internal height of the case for a battery. (Except for the SIM socket under the battery Mobile style.)

If we kept the rear of the case simple, Expansion connector, 2xUSB (Stacked) 1xPower (Same as Zauri - 5V), HDMI, that means that other peripherals can be put on other edges, CFIO at left, the stacked or parallel SDIO on the front.

Apart from the electro/mechanical difficulties, the Clamshell screen makes alot of sense, because it gives extra space at a small volume cost, for example the speakers, camera, and (I actually Really like this idea) a Thumbprint scanner could all be on the screen panel while removing space constraints on the main body.

Are those prices USD? If yes, then I can see a cluster being a cool piece of equipment. say 50USD a blade, a cluster of say 10, would give a nifty BEOWULF dev cluster. I take it they'd load the OS over Network? Cool idea.

RS232 Jtag by the way please! XP

One big point, The Aerial socket can't be flush. If you've ever seen the antennae I'm talking about, they have a big plastic surround at the bottom which screws over the connector.

And another thing, what about a jog-dial? It's the one thing about my clie that I really thought was genius. On the front(right) panel?

Also, with a 2A power drain, that gives us less than an hour on a standard battery (1.8 Amphours, 1800milliAmphours)

That might not be a problem on what is basically a mini laptop that's going to be used as a mostly-mains computer, but for a PDA. . . WAAAAAY overbudget. We need to half that with all peripherals on, and get it even smaller with peripherals off.

I'm looking at say

2 Hours (1Amp) with Phone, Camera, Bluetooth, Wifi all on,
8/9 hours Phone only.

http://www.wirelesspro.co.uk/product_info....products_id=332

That's the antenna design I was thinking of.

At some point I'll do a few more sketches of a PDA design. Anyone here a blacksmith?
stampsm
try adding the docking connector like i was saying so you can have a docking port or slieve with a pcmcia, camera, and other stuff you could not stuff into the base design availible for those who would want it.
stampsm
on that blacksmith point actually yes. smile.gif i got a 95% completed forge construction project i am working on in my backyard. smile.gif
Ferret-Simpson
Fancing making cases for the PocketPenguins?

And I'm still hoping we can get a camera on the screen. It's not taking up any real estate inside the body except for the control lines that way, right?

And the expansion connector I was talking about is the connector for the backpack.
Da_Blitz
I think you miss the point on a flush connector, what i used to use was a flush connecter on my wifi cards and a female to female adaptor when i needed anything to be connected, this ment that things didnt get caught in the cases i pack everything in, works well

i was hoping to put the fingerprint reader on the board next to the keyboard and have the screen take up the whole face but i guess if we have room then the speakers would go on ethier side, however i agree the cammera facing the user should be on the screen but i belive tha the high quality camera should be an the board itself so you can twist the screen and make it into a normal looking camera (running linux with GIMP wink.gif)

also i wanted to have a small auxilary screen on the outside of the screen with 4 buttons to control things like music

as i use the thing in lanscape all the time it make sense for me to have it at the back, alse having it at the left means less room for the expansion connector unless i move that to the back (that may be a better way to do it for a docking station) but i guess a compermise is to put it in the corner and make it wide angle, best of both worlds

Jog dial is a must, 2 if i can fit themone on the back and one on the frount so when you have the case closed and in portriat mode you have the screen on the frount with the current song with controls to play/pause and a jog dial on ethier side for next/previos and volume up and down

LOL, 2A power consumption is crazy, i was talking about battery capacity, i am trying to fit in with a power budget of 200-300mAh, this chip seems very low power and by turning things off it makes it easier to achive, the microdrive will break that but its not an all the time so we save power that way

i think its safe to say we can drop the addin card in favor of the backpack/expansion connector

In reference to the laptop and blades i was thinking to have in total the Blades, the PDA and the laptop. the blades would be proof of concept to allow me to have a cheap way to check that all the iMX3 stuff works and allow for a very cheap dev platform, next would be the PDA which is the same as the blade except now i test with new hardware and finally the laptop would be the pda boaurd and an expansion card plus a hard drive in a laptop case

the blades would boot of the network onec every thing is done, i was thinking having a card that the CPU cards slot into (think motherboard and PCI) that has edge connectors with ethernet and serial so you can hot plug them, one advatage is if the jtag port is on that connector then i can use it as a programming interface

the boards bieng so small means i can get them built cheaply, the only problem is that for the minimum order i am looking at mabey 20 of them unless i go thregh a diffrent manufacturere for the prototype

might get a couple of pics up in the next week or so of what i am thinking of, both of the PCB and the case
stampsm
there is a cool electronic site called sparkfun i like to go to.

they just had a new product listed that would be interesting for a pda

Da_Blitz
Thanks for those links, i was going to sugest droping the touch screen in favor of a joystick but this is much better (besides the fact that every one seems to want a touchscreen), i think this would replace the directinol pad wink.gif

everything else is alright but i can buy all that stuff from my local electronics store

for the parts as these will be assembeled by the PCB people, getting parts is a bit of a non issue scince the bulk all thier customers part orders together for reduced pricing, i would however like to use freescale parts where possible to keep it consistent

had a thoght and would like comments on it, i want to frezze the inital feature set in about a week so that i can look for suppliers for everything, so should we do this and if so what do you want in the frozzen design (it will only be frozen until i can find all the parts i need then i will unfrezze it and start the process again until we are happy)

for wifi i am thinking somthing madwifi compatible as they have some very cool features eg concurrent running in both AP and station mode multiple concurrent (virtual), access points QoS, Roaming, scan available channels without losing the current AP association (switches to scanning and buffers outgoing transmissions)

bluetooth wise i would like to use a 2.0 adabtor with the enhanced data rate but that module gives me a good benchmark for size

what i feel i will need is an RF egineer for the wireless stuff

once again "holy ****" i like that trackball, keep sending me this great stuff
stampsm
i was looking at the size of that trackball and it looks like it is the same size as the ok button on the c series z's. here is a image of the zaurus keyboard

i was thinking of having the middle ok button replaced with the trackball and keeping the 4 dirrectional arrow pad. that way you can scroll through the icons with the dirrectional keypad and press down on the trackball for the ok button. the having a button to the lower right ( mirror image to the cancel button on the left) for a switch button to switch between mouse mode and ok button mode (need to find better words) another good part about the trackball is 2 different build in led lights that light up the ball. you can use the two different colors to signify whether it is in mouse mode or ok button mode.
this way you keep the dirrectional keypad all z's have so software will work out of the box with no modifications needed and also you get an integrated thumb mouse with only about 1/8 inch increase in thickness in the center part and a very small increase in the width of the key pad part.

ohh yea found who manufactures it
http://www.ittcannon.com/products/products...pid=10568&cf=pl
stampsm
in the next week or so i can try working up a prospective 3d model of the keyboard design in blender so we can see how it would work and be able to modify it and view it while working on it
stampsm
also iteam #6 on that ittcannon page link would make an excellent jog switch
stampsm
the trackball has green, blue, orange, and, red led options. so i was thinking blue for regular ok button setting and red or orange for mouse mode

I like your ideas alot, seems we have a couple of topic watchers as i come bock 5 mins latter and reply again wink.gif

have a look at this 3G chip it does Global System for Mobile Communications (GSM), General Packet Radio Service (GPRS), Enhanced Data for GSM Evolution (EDGE) class 12 and wideband code division multiple access (WCDMA) and high speed downlink packet access (HSDPA).
http://www.freescale.com/webapp/sps/site/p...=01J4Fsm6cyDbFf

looks like we will have to liscence a stack unless someone knows thier way aroud this stuff (but we are talking decoding and all the other stuff for several diffrent protocals)

also it looks like we found our jog-dial, nice pic i wish i had a black case and i like it how in the pic the crome looks like gold

That reminds me how about wirless usb, there is a linux project in the works at the moment and we wont be able to use it yet but it would turn this into a UWB testbed for linux people (and helps us get drivers quicker)

i thoght we could turn one of the usb ports into a wireless one, ideally we would have wireless client and host but i dont know about any chipsets that can do that

anyway we can get an estimated cost on those chips?
stampsm
i love freescale products. i think it might be cool to put a footprint for a tri-axis acelerometer on the board so you could detect the orientation on the device. (games anyone smile.gif ) the footprint is small for the chips so you could add it and just not populate it unless certain users want it on since the chips cost about 6 dollars each for the tri-axis ones.

count me in. i have been looking for a project to work on.  i also got a few nice toys like a ulink jtag debugger and a few dev boards for procesors like aduc7026 lpc2138 lpc2119, ect. ( i love ebay ). the dev boards i have are mostly for low end arm processors though, so i am thinking of getting a dev board for some higher end arm processors, but i am a poor college student so my budget is not to high. i have tried a little at designing pcb but i have never got the hang of it. you can kind of say i am a jack of all trades. 


sorry i missed that post earlier, glad to have you on this project, as for me i am 1 week away from cmpleating an electrical engineering course and have some money stashed away for this project, one of the problems with my board manufacturer is that they tend to have a minumum of 2 to 5 boards so its likley ill have some spares to give to devs or people who can enhance the project at a reduced price but dont qoute me on that

as For openPDA corp (ive been reviewing everything said) i have always been using DaBlitz Heavy Industries (homage to old japanese Mecha animation, nearly every mech company had deavy industries in the name) and would like to keep the Heavy Industries part (i just imagine it looking cool on the case see: http://www.bit-tech.net/modding/2005/09/23..._kos_mos/1.html and have a look at the logo for vector industries) but really when it comes to that stuff its up to you guys
Da_Blitz
seems you have the same idea as i have, the reason i want to use freescale chips is that they seem at least semi-frindly to open source

I actually have an accelerometer from them sitting here right next to me and if used with the trakball you would have a very nice game console, Imagine that trackball with quake and vibration/rumble support (this is a phone after all)

also dont forget it has "OpenGL" support not "OpenGL ES", thats why it has a floating point unit, this along with the video decoding and post processing stuff would allow you to do some incredible things

i think its time to clean up what we have as i have sugested alot of stuff to get people thinking and to add it all will be hard and exspensive.

as for prices they dont list those and some chips dnot have much in the way of infomation, it looks like it will take me some time to type up a letter explaining what we are trying to do and request infomation from them, plus see if we can get small quantites of thier chips

found some info on phone consumtion, the chips consume 200mA when fully active (making a call) but idel at lower power levels, in an ideal world you wouldnt even need linux to recive a call (thats how i am going to try and implement it) but i think that we might need linux to act as a routor to the audio hardware, but thats fine scince the cpu will be idel when making a call most of the time

on the plus side i have found some REALLY juicey SDIO infomation on thier site whigh i plan to foward on to some people

what i would like is Distro devs and kernel devs input, they might want somthing uniqe that will make thier life easier, in fact i wish everyone would post on hear about what the want as the poll has too many limitations to be able to vote an all these features, so far we have seen some very nice stuff to the point that if i was not doing this project i would get one of those tracballs and put it in my Z right now wink.gif i really like them (beats HP's hx4700 touch pad by a mile)

so i think my final short list comes to (in order of prefrence):
The trackball
iMX3 processor (thoght that would come first didnt you)
between 128MB and 256MB of mem (DDR wink.gif)
Jtag and serial
Up to 2GB of Flash
Backlit Keyboard
USB 2.0 Host (as we can do video sound and nearly everything from here)
Video out (HDMI)
2x Jog Dials
Bluetooth
Accelerometer
GSM/GPRS
2 SD card slots
Microdrive ar CF mem on ATA port
fpga (for use in conjunction with the docking station)
Docking station (not backpacks but a small station for it to charge from with USB hobs and whatever (vga out?))
Back packs)
CF+ (a CF slot basically)
Wifi
Auxilary Display + buttons
3G
Camera
DVB-T/H
USB Client (I never use it and there are already better options above here to connect to a network like 10/100 usb adaptor)
UWB

Things i wont put on it:
GPS (in my opinion its better over bluetooth and more useful that way, eg can then be used with laptop and also has its own power supply)

Case wise i think aircraft grade aluminium but i would prefer black carbon fiber smile.gif I personally think that the case will make or break the design, if its sexy to the point where if you pull it out on a bus people will look and drool and wont run away when you say it runs linux but instead ask "whats that" then i would say we have sucseeded

to sum it up i mant a case that puts the curves of HP 1900 series and the htc phone series to shame and i belive blak with a tiny amount of gold trim is the way to do it, plus lose the boxy look of our clamshells and go more like xda4 rounded/oval tablet style, it looks good in blak but would be awsome with a small gold trim

well if you put two sd card slots on it i would recommend putting less flash built in. the flash memory should be primarily used to hold the OS and a few aplications. also for some reason SD cards are cheaper that just plain flash chips. that way you can put the more common accessed files on the internal flash and use the sd card for the bulk storage. actually if you put an internal CF slot and an external one on it plus two SD card slots i would have just enough flash to hold the OS plus maybe 20 megs on top of the OS size to put user aps and bigger OS images. with 2 4gig CF/microdrive and 2 1 gig SD you already got 10 gigs of potential storage or more.

i can work on getting a keyboard design figured out. most likely it will follow the same basic design as the c series zaurus's but with a few modifications
Ferret-Simpson
Ok. . .


The i300 chip is designed as a central core processor that would replace the iMx31 chip. . . NOT a good idea. (Lose at least 130mhz, plus alot of the funkay features)

A big internal flash is good, but on the meantime, let's not go overboard. I think a flash of around 256mb to 512mb would be reasonable, 512 preferrable. That gives us the option of using all our expansion as expansion, instead of just an offboard OS storage.

TWO cameras? WTH??? If we have a rotating camera on the lid, then we can rotate it 90 degrees to get a normal camera anyway (Clam open.) One high quality Cmos is cheaper than two. Also means we could use the trackball as a "Take Photo" button.

Also, on the note of the trackball in the D-pad. . Great idea! But changing modes? If you've got your thumb on it it isn't going to move much. . . But anyway, whatever. If the ball is illuminated, instead of showing trackball mode, why not use it as the power indicator?

When I was looking at the thumbpad idea, my case design had it on the back of the screen panel, or on the front of the screen panel, next to the display, like the new Asus RF1 tablet.

And silver > gold.

Aluminium is a much easier to manufacture (and likely cheaper) case material than Carbon fibre. And what you talkin' about fool? Curved design removes space for connectors and internal circuitry. Besides, you've got a black PDA with a camera, huge screen, Phone, Wifi, Bluetooth, USB, 2 SD cards, Compact Flash, TRACKBALL!

Who the frakk isn't going to notice it?

Also i vote blue LED's. Sky blue. ^^

Freescale is good, I've been a motorola fan since my first amiga. (Now have four, and two palms.) But that Phone chip isn't. It's a replacement processor, not a coprocessor, and is designed for simple mobile phones.

WE ARE GEEKS! LOW PROCESSING SPEEDS ARE BELOW US! |nosebleed|

Internal Microdrive is a big drain on power. . . If it can be done, fit the socket, But with 20GB MicroDrives due next year. . What's the point? Anyway, I'll have a look at sketching out a new case design at some point, if Stamp wants to do that keyboard plan?

And yes, I want "Windows" Keys. XP Okay, Okay, I'm kidding I promise! But Ctrl and Alt are a MUST! O.O

i just did a scale drawing of the c3000 keyboard last night and i think it would be no issue to follow the same format and add a few of the "forgotten" keys. i originally wanted to make the keyboad amidextrous but i realized that if i put the dirrectional pad in the middle it would be to hard to reach with thumbs it seems.

Hey, good thinking! I never thought to use a rep-part screen. Can we get a datasheet on this? No good in having a screen if we can't interface to it after all. . .

But good work. ^^

Also, while I was on SF, I noticed these. . .

Instead of a replacement for the iMx31, a Quad band version of those modules is what we're looking for.

This has GPRS class 10 too. . . .

That's functional in UK, USA and Australia. . . No networks still use 800 so they?

Ah well. . . It's good to have that as a backup plan. XD
