== myPhone is a TuxPhone ==


The TuxPhone proved the basic concept of a completely open phone (COP) with open software ''and'' open hardware, with all specifications of all the components freely available.

; Software : See the [[open mobile software]] page.

; [http://www.widgetry.org/dokuwiki/doku.php OpenCell] : OpenCell is being built by a team at Florida Tech, and we are sharing ideas and encouragement. They have published [http://www.widgetry.org/dokuwiki/doku.php?id=schematics circuit schematics].

'''myPhone''' can be built from the following components, in any combination, landscape or portrait oriented screen.

; Case : a customizable case that can be produced on a 3D printer. A [[first attempt at a bezel]] and an initial [[myPhone case]] for a 4.3" LCD have been designed using Alibre Express and printed at [http://techshop.ws Techshop]. A more sophisticated [[portrait oriented case]] for a 3.7" LCD has been produced and design files posted.

; LCD Touch Screen : [http://www.sharpsma.com/Page.aspx/americas/en/part/LQ043T3DX02/ Sharp 4.3" 480x272 pixels] as used in the Sony PSP, with a [http://www.hantouchusa.com/drawings/HT043A-NCOFD52.pdf Hantouch touchscreen] overlay added. This LCD has deeper color resolution than most, a true 8bits/pixel rather than 6bits for many others, but has relatively low pixel resolution. It's a low cost option, that needs more complex interfacing circuitry.
: There is also a higher resolution 4.3" at 800x480 with integrated touchscreen that is being investigated.
: OpenCell and the portrait oriented myPhone are using a [http://www.sharpsma.com/Page.aspx/americas/en/part/LS037V7DW01/ Sharp 3.7" 480x640 pixels] which is portrait format with integrated touchscreen and easier power supply integration. Its derived from the Dell Axim 50V PDA screen.

: [http://www.freescale.com/imx31 Freescale i.MX31] is another option that includes graphics/multimedia processing, more open documentation than the later models in the PXA series, and will be the basis of a more compact custom design.

; Codec : [[UCB1400|NXP UCB1400]] audio CODEC with integrated touch screen controller and power management monitor

; WiFi/Bluetooth : Still researching the best options - The Atheros AR6000 is one possibility. Many chipsets do not have open specs. Since they operate on the same frequency, a combined chipset is needed to coordinate transmission, possibly with combined antenna.

; Camera : It would be nice to have a front mounted camera option for people who want to build video-phones.

; Video-out : A TV-compatible video out feature would also be useful for presentations and projectors.

; Battery : many options, but one high capacity, low cost, easily available possibility is 51x39x9mm [http://www.batteries4less.com/palm-handspring/treo-650/batteries/palmone-treo-650-treo-650-oem-3184ww-extended-battery.html Treo 650/700 3184WW 1800mAh].
: A higher capacity option in the Treo form factor is [http://www.treo-gear.com/store/catalog.asp?item=2581 2400mAh] I bought one of the 2400mAh batteries, and its the same size as the 1800mAh. There is a 3200mAh variant that is 3mm deeper.

Work is in progress on this page, capturing all the specifications and URLs.

More information about generic hardware avaliable to build other phones is avaliable on the [[Hardware]] page - This is also work in progress :-).

== Open Microprocessor Module ==
An [[Open Microprocessor Module]] design based on the Freescale i.MX31 has been started, and may serve as the basis for a broad range of potential mobile devices including MyPhone.

==Notes about Options==

===GSM Module===
; '''GSMStix''' : Craig over at [http://www.gumstix.org/ GumStix] has talked about the GSMStix they're working on. The last I heard it was going to use a [https://pia.khe.siemens.com/index14287.htm Siemens MC75] module. Though I could be wrong. Craig says he likes this family of parts because they have direct digital audio i/o. At 34mm x 45mm it's only a shy bit smaller than the Telit module. But hey, it does EDGE, it's smaller and it has digital audio i/o, and it doesn't use a BGA grid, so it's possible that mere humans could solder them on to their project boards. But... I don't think we've found a reseller who's distributing them in single quantities, and there was a tempest in a teacup about NDAs and so forth. News is the NDA issue was a red herring, they didn't have problems distributing technical docs, but didn't want to talk about pricing without an NDA. For us, that's probably no biggie. Plus, if GumStix builds it into a standard part, they'll make a bulk order and sell them to individuals. So when the GSMStix is released, it'll no-doubt be a cool product that should be quite usable. 'Til then we'll probably have to make due with the Telit modules.
; '''Telit GM862 Family''' : This is where many of us got our starts. [http://www.sparkfun.com/ SparkFun] sells members of this family in single quantities, along with proto boards. You can find some links to info resources on the [[SqueakyMoPho Project]] page.
; '''Telit GE863 Family''' : So Adrian and I were eyeballing this module after playing around with the GM862. It's listed in the SparkFun catalog, but the last I checked, they were out of stock. And with the release of the GSMStix, it may not be relevant. But, it's smaller than the GM862 family and it looks like it might be easier to attach a smaller antenna to the thing. Telit has a [web site] and [http://www.telit.co.it/data/uploads_EN/products/Telit GE863 Family Brochure.pdf PDF Brochure] about the GE863 family.
 
===LCD Screen===
; '''Sharp 4.3 inch screen''' : We were originally looking at using the [http://www.sharpsma.com/Page.aspx/americas/en/part/LQ043T3DX02/ Sharp LQ043T3DX02] with a HanTouch touch-screen. This is the same screen that's used in the Sony PSP, so we figured there would be several of them in the supply chain. But surprisingly, we couldn't find a reasonable price for the "official" sharp products, and the device required a couple different voltage levels, so for the time being, we punted on the thing in favor of the 3.7 portrait display below. These displays use a FH12A-40S-0.5SH(55) connector (that's a 40 pin .5mm pitch connector) for the main interface and a 4 pin 0.5 FPC style connector for the backlight. The reference connector for the backlight is the Kyocera 6298. The Hantouch touch-screen recommended is the HT043A-NCOFD52 which uses a for pin FPC type with a 1mm pitch, so something like a BL110-4 should work. There are a few after-market suppliers who say they have "compatible" displays for a way cheap price, and we may buy a couple to experiment with. If it turns out that they work, we may yield to the lure of cheap LCD screens and make the landscape myPhone with this screen.
; '''Sharp 3.7 inch screen''' : The [http://www.sharpsma.com/Page.aspx/americas/en/part/LS037V7DW01/ Sharp LS037V7DW01] is the latest LCD we're thinking of using. We were able to get these displays at about the same price as the PSP displays through official channels, and it's a better display overall, so we're going with it. This display appears to use a single input voltage level and a 51 pin .3mm pitch connector (like a Hirose FH23-51S-0.3SHAW(05)). Which means it will be a total pain in the keester to solder.
; '''800x480 screen''' : Rumors abound that we can buy the 800x480 screen that Nokia uses in the 770. If we can't find a cheap, reliable source for the PSP display, we may try to track this one down.
