Nikolaus,

I agree you should first play with something that is available.

The information I got is from eurocircuit.com,
The price is based on 4 layer 150 * 60 mm; just a wild guess of the size and
layers based on standard technology, but giving an indication.
More about the possibilities can be read in
http://www.eurocircuits.com/images/stories/ec09/ec-services-leaflet-uk-english-4-2010-v2.pdf.
I did not check any guidelines and requirements, so hard to say what suits.
If somebody could provide more detailed information or point in a direction,
a more serious price could be obtained.

Regards,
Martijn

 Yes,
 this all can be considered for a future version.

 What we wanted to start with is something that just works, is easily
 available, can be used for experimenting and software development and is not
 too costly. A nice case, a new PCB for the OMAP processor or using the
 Gumstix makes things much more expensive.

 @Yocto: what has to be considered is that the Gumstix does not fit into a
 Freerunner case (it is still too large/thick).

 @ Martijn: the OMAP BGA poses high level requirements for a new PCB. So I
 would be surprised if one can really get such PCBs for 15 € @ 50 units. But
 do you have more information? What have been your assumptions about # of
 layers, min. drill size, min. width etc.?

  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.

 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 ].

 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.

 Martijn

 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:
