Yep, you can do it now…..The open source hacker community GizmoForYou is shipping a Linux hardware/software kit for building a modular touchscreen smartphone. Using the OMAP35x-based Gumstix Overo Earth single-board computer (SBC), the Flow phone offers numerous customization modules including GPS, 3.5G cellular, Bluetooth, WiFi, and a camera. At around $1300 for the complete kitchen sink version, it’s not exactly cheap, but since they offer multiple choices for each component, you can pick and choose what you like to have inside your smartphone. Really neat stuff.
For those of you who are not tuned into Gumstix, the Overo line is a new line of Computer-on-Module devices designed by Gumstix based on TI’s OMAP Processor. Overo Earth comes with the following specs:
Processor: OMAP 3503 Application Processor with ARM Cortex-A8 CPU
Size: 17mm x 58mm x 4.2mm (0.67 in. x 2.28 in. 0.16 in.)
The core of the Flow phone is the Flow motherboard, which is designed to integrate the separately available Overo Earth module. You can also use the more expensive Overo Water, Air or Fire modules. Other modules attach to the motherboard, including a 3.7-inch 640 x 480 Sharp LS037V7DW01 touchscreen LCD and Flow Sharp LCD module.
Connectivity modules include GPS, USB, and a choice between a plain GSM cellular module and a HSDPA-ready 3.5G/GPS/GSM/GPRS module. (WiFi and Bluetooth are already supplied by the Overo SBC.) Additional options include a 1GB MicroSD card, camera, power supply, battery, and enclosure, with various options available on several of the modules. Flow motherboard features include:
GizmoForYou does not say much about software, but there are a growing number of Linux development platforms supporting the Overo Earth and OMAP35x platforms, and according to a project member, the group is working on an Android implementation.
