Return to Modular phone.
A number of manufacturers produce modular components suitable for embedded systems. Some of these components are suitable for a hobbyist to put together a modular phone. This page is intended as a starting-point for building an OpenMoko compatible phone.
The major problem with this approach is that the resultant phone tends to be larger than a normal phone.
This is because though they may be designed to be compact, internal connectors add lots of volume compared to a PCB, where everything can be in one unit.
This is more than likely true. Gumstix produce 3D models in Sketchup format, of all their components - I will produce a 3D mockup using the components listed below, upload it here and make a size comparison.
The prices for the Goliath daughter cards are realeased on monday 16th July 2007, and should be around $100USD, giving a total of around $450+, which compares with the Neo1973 at $450.
Prices will be reduced, if we as the OpenMoko community buy in bulk.
Capabilities wise, this compares well with the Neo - there is no accelerated graphics and the screen is smaller, but it does have EDGE and a faster processor. Otherwise specs are similar.
Where relevant, all components listed here have Linux kernel modules supplied by their manufacturer.
Home Brew Mobile Phone Club have a site devoted to build-it-yourself mobile phones, based upon Gumstix motherboards. They have schematics, case designs and details of suitable components from many sources.
