nonononono!

I'm NOT saying we shouldn't put it in! Just that we should make sure it's fine as a phone TOO!

There are Cheap Data placs over here too, but if you get a Data Price plan here, it don't do phone calls.

we have to start thinkning internationally (esp. ferret-simpson) and relise that in the rest of the worsd things may be diffrent

over here in australia its 20c per KB and 1 sms costs 20c (last time i checkd, might be out of date) basically it was cheaper to use msn than sms

if you own a buisness you basically get given unlimited gprs for free, but for individuals you pay quite a bit, unless you are on a capped plan (ie spend 200 but only pay 60, i dont know why they dont make everthing chepaer instead )

the main aim is "mobile office" so phone functionallity takes a backseat to data transfer. in any case its a software thing and dosent really have any impact on the design at all (as all gprs modems i know of can do voice and voice can do gprs))

in any case it appears that we have too many divergint factions here. its time for me to decide very specifically what the motivation and aim is and as a sneak peak i will say mobile office again

what I have now (though it clearly needs better integration--mea culpa)  is a cell plan for a flat fee plus a data plan over the phone for an additional flat fee. It all works on a standard (north america +world triband atm) gsm phone using a sim card.

It would be very cool if the PP could handle phone and data over gsm and made use of my sim card.  This would get me down to 1 device, or 1 device plus headset.

I would be ok with using either my voq or my nokia 6310 or other such gsm phone as a phone + modem for the PP.  Possibly the need for the PP to access radio frequencies worldwide might dictate this approach. i don't know.

Maybe it would be better, in a large sense, to put energy into software that talks to cell phones and cell phones as modems rather than making hardware to replace the phones. I can go either way, so long as I can get things to actually connect (I need to spend more time on the voq stuff...and my isp tech support people have no clue at all about connection info at their end).

I guess, as usual, I'd suggest that making the PP the best pocket workstation possible should be the priority, and the other stuff (phone and modem) should be done in a way that conforms to, rather than distorts, the primary goal. However, at the very least, good connectivity software might end up becoming an issue...

In terms of licensing stacks etc. .  This is probably slightly illegal. XD (Unless you own a Universal aswell) But if you used the same hardware as in the Uni for the Modem/phone, and I mean EXACTLY the same Ram/Rom chip, processor and chipset. . If Universal Linux gets phone support, so will the PP. .  just a thought. Because, You could UPLOAD THE HTC PHONE ROM!

I'm just not going to make comments about hardware design any more, You guys are all on a totally different wavelength to me.

.....which brings us back to the good cellphone connection software and leaving the gsm to the phone, rather than as a part of the PP, right?

well the funny thing is that the phone on the PP would look exactly like any other phone you can throw at it, wethier it be over bluetooth or usb. the only thing that is diffrent is how the audio is routed

if it comes down to it i guess the order i would want to see implemented  (for a work station) is buetooth, wifi, gsm simply because the bluetooth allows a gsm connection and can be made to do tcp/ip. at a minimum i would like to see wifi and bluetooth

i am starting to change my mind on modules a bit, after looking at the size of some i am starting to like the idea a bit more, the only real problem i have with them is the hieght which at this point in time could become a factor to consider

Yeah i find it handy every now and again (i finally got a phone with a camera, because i dont have a camera) but i think it will most likly be dropped

i still want to include the pinout for an image sensor however as there are a couple of trics you can do with  it if you are creative

"Ultra low power graphics and co-processor
Silicon Motion is continuing to expand its mobile graphics product line with the introduction of the SM502, available in the UK from Sabre Advanced Microelectronics.

The SM502 is an enhanced version of the SM501, with increased 2D and video acceleration performance and ultra low power consumption for resolutions up to 1280 x1024. It has a flexible bus interface supporting a direct connection to 32-bit embedded CPUs or PCI 33/66, and dual ZV port with ITU656 support for multiple data stream capture and real-time display and colour space conversion capability.

Other key features include a programmable panel clock (PCLK) for frequency customisation to support standard and non-standard panel timings; integrated I/O; 0 or 8MB integrated memory; and LCD, CRT or TV support with flexible display configurations.

The SM502 is pin-to-pin and software backwards compatible with the SM501.

How about this display?
7" TFT at 720 x 480

http://www.johnlewis.com/Audio+and+TV/Came...67/Product.aspx

it'd be nice to know what the actual display module inside is, but since we know the finished product is GBP170 it means it should be possible to buy the display for maybe GBP80?

has anyone identified whether its possible to buy the display from a Nokia N800 as a separate module for a reasonable price?

i just managed to pick up a sl-6000 for a good price (237 USD  ) and the 4" screen on that is about the max i would want to go. maybe a 5" widescreen format but no way a 7" screen.

Here is a new chip(set) from Broadcom that integrates BT and 802.11a/b/g, and even FM radio!  Unfortunately, I think Broadcom is one of those Linux hostile manufacturers.

And, here is the equivalent from TI..  TI's also supports 802.11n

so as promisedi am designing the power supply at the moment however some other chips poped up that could be nice

Return of the finger print reader: http://www.atmel.com/dyn/products/devices.asp?family_id=609
allows for psedo mouse support (its basically a laser mouse with a wierd sensor)

anyway back to power, at the moment i am looking at getting a power supervisor, the davantage of these things is they pack alot of diffrent power regulatiors for diffrent pourposes, they are small and can be heat sinked eaisly and they normally pack extra goodies (the freescale one has audio in and out, a RTC, power on at certin times of day, lithium ion charger and a USB PHY that supports client and host, but requires an NDA so it wont happen )

the design spec at the moment is between 5v to 18v input, if you dont want to care about polarity then i could add a rectifier however most chargers are "standard" and use the same polarity and the regulator is just waste heat and board space, if you dont trust yourself to get the right charger then charge over usb.

current wise i am looking at at least one chaneel that can do 1A @ 5v for USB, for the rest of the support circutry i am unsure, it depends how i partion the devices however there will most likly be a .5A for the cpu and .4 for the RAM with .15A for several of the extra chips (ie audio, bluetooth). i will make sure wifi gets the power it needs

i will try to give each subsystem its own regulator (the chips i am looking at are 7 channel) so that you can fully turn off any subsystem you are not using (audio comes to mind)

one thing i may be able to swing is a proximity detcetor for the keyboard, using the backlight itself, LEDs can be used as solar cells, yada yada yada, look on hackaday.com for more details

for refrence i like the natinol semi LP3941A, it does the full LED driver, I2C programability and has backup battery support as well as Liion charging and its 11 channel !!!! (http://www.national.com/pf/LP/LP3941.html)

one thing that has come up is that this will be mainly a 3v system, so any I2C connections on board will be 3v, however i may be able to swing it to the 5v usb line to make them 5v, not really much of a problem due to the nature of the bus but it could play havoc if you dont get the voltage you were expecting (meeats TTL requirements but not cmos off of the top of my head or the other way around)

the natinol has a problem in that it cant go above 5.5v so it would be a 2 chip solution (not really a problem, it only means i need to put an extra chip between the power plug and this thing so that regulator would be off most of the time)

apart from that the natinol semi chip is rock solid and requires little in the way of extra parts, 4 ar required, then one capacitor per Vout, so its safe to say this part is done

check the next post for whats next
