Could we, also, consider the option of using a "smaller" board like the Gumstix Overo ? OMAP3503 with ARM Cortex-A8 at 600MHz 256MB RAM / 256MB Flash [ 17mm x 58mm x 4.2mm ]. http://www.gumstix.com Regards, // Yocto ----- Original Message ----- From: Martijn van Dongen To: List for Openmoko community discussion Sent: Thursday, May 20, 2010 5:00 PM Subject: Re: Openmoko Beagle Hybrid Hi, First of all: nice project, could be a nice follow up for the freerunner. I have been looking at the discussions a little bit. Main discussion is how to make a new casing that fits around the beagle board, how to produce and what it costs. I haven't seen a discussion about redesign of the board, the design files (schematics in Orcad) are available, so you can downsize the connectors used and fit it in an existing casing. I have a price of a PCB (without parts) at low volumes (50 pieces) at less than €15. Assembly of low quantitiy boards will be very expensive (make it double the components price), so a DIY project for assembly of the boards will make the PCB fit for a reasonable price. Regards, Martijn 2010/5/11 Dr. H. Nikolaus Schaller <h...@computer.org> There is now a new Wiki page for the project: http://wiki.openmoko.org/wiki/Openmoko_Beagle_Hybrid I have received some questions why we did not put all this into a nice design. The main reason is that we can't redesign the Beagleboard (it has fixed dimensions) and we can't afford to build plastic injection moulds (if someone has an idea how to reduce cost this is very welcome). So the easiest solution was to combine what we have: a given Beagleboard and the Freerunner case. Other questions were what one could do with this. Here some ideas (not assuming it is complete - you may have more and it is a platform for your creativity): • experimenting with touchscreen and new user interfaces on Beagleboard • learn how the OMAP3530 CPU works • make it a truly open mobile application development platform by adding a battery pack and a UMTS usb stick • investigate how an Openmoko with UMTS and OMAP3530 feels (not from haptics but screen operation and UMTS speed) • porting SHR, QtMoko, Android, etc. to ARM-Cortex A8 And here some feature list: • PCB that fits into Freerunner case (top cover and middle part after cutting a hole) • works also without such a case (except speakers and earset) • Toppoly LCM interface (same display as used in the Freerunner - otherwise it would not fit into the case) • TSC2007 touch screen controller • Microphone • Earset and Speaker connector (for those sitting in the Freerunner case) • 2 buttons (AUX and Power) • 2 dual color LEDs (in the AUX and Power buttons) • vibracall driver • headset jack to connect microphone, earset and speaker For the software, we have to rearrange the code on our server a little and then it will be made public. Finally, here you can do preorders: http://www.handheld-linux.com/wiki.php?page=Openmoko%20Beagle Nikolaus _______________________________________________ Openmoko community mailing list community@lists.openmoko.org http://lists.openmoko.org/mailman/listinfo/community ------------------------------------------------------------------------------ _______________________________________________ Openmoko community mailing list community@lists.openmoko.org http://lists.openmoko.org/mailman/listinfo/community
