Open Mobile Gadgets

This is a description of a project to create an open software, open hardware mobile communications device. Initial iterations will be very simple, but will progress to having full smartphone-like functionality and beyond.

The Open Mobile Gadgets Architecture

Here's a quick block diagram of the device that I want to build. More details to come about the specific hardware implementation.

Is this the same as the "Open Phone" ?

"The Complete Open Phone" by Matthew Hamrick, 2006-09-05

("Matthew Hamrick is the co-founder of the Silicon Valley Homebrew Mobile Phone Club ... Matthew ... proposes a truly open mobile phone platform.")

Even if it is not, would it be a good idea to join forces, share resources, etc. ?

Is it really possible to build a cell phone with "reasonable" weight and battery lifetime using mostly generic hardware (a FPGA, a Kilocore, off-the-shelf ADCs and DACs, etc.) and lots of software, rather than hard-wiring everything with custom hardware?

... See wikipedia:Software-defined_radio ...

• Nope... this isn't the same as the "Open Phone" stuff I'm doing.

But... "Complete Open Phone" is more of a concept than a project really. So if you're designing mobile-phone like hardware that you release with an "open" license like Creative Commons or Gnu Public License, to be used with "open" mobile phone software like Familiar Linux or LIBGSMC, then you're doing the same thing I'm talking about.

I'm the first person I know who's called for opening up hardware and software for mobile devices. I hardly belive I'm the first person to come up with the idea, though. It's a good idea and given the number of highly capable geeks out there, it's an idea that you won't be able to put "back in the box." In other words... "Complete Open Phone" is just the name I came up with for a "movement" that I and other people have been working on (people like Surj Patel (who runs the Open Cell Phone site.), Casey Halverson up at Seattle Wireless, and Nathan and all the gang at SparkFun.) And now that I've finally browsed over here, I can tell other people that the "Open Circuits" community are also interested.

Some of us at the Homebrew Mobile Phone Club are (in our copious spare time) designing and building "open" phone designs. We're more interested in building phones than web-pages, unfortunately. But, I'm hoping to have the time over the holidays to post a few pictures and designs. You'll find more information at the Homebrew Mobile Phone Club Wiki and we'll probably post instructions at the Instructables web site. Heck, we'll probably also post some designs here, that what it seems to be setup for.

• I'm interested in putting together an open phone too, but I'm more into a basics first-grow later using the GSM Module from Telit, the GM862-GPS. My idea is to use just the module by itself, code in a very basic "operating system" using the module's python capabilities, and a Nokia LCD that they have in sparkfun. I wish to buy this module because I think that every cellphone should have GPS capabilities even if it's an add-on. I also like this module because you can use it from the start without a lot of external components (it's got a battery charger, IIC, SPI interfaces, AT Command set, integrated SIM reader, etc etc).

I *do* have a problem to create the PCB and buy/place some of the components, so, would any of you guys interested in collaboration with this project ? I can come up with the initial desing/PCB and we can go from there. One of the ideas is to have the module as an add-on to the Palm TX pda. I intend to use a gumstix later on too maybe (if I don't go the TX way). Let me know if you're interested. BTW, shouldn't a *discussion* on this page be more interesting ?
