It always seems like it works out this way. Secret sources to be named "soon". Untested near-products that aren't quite ready for release...

Lets do it with stuff we can get and see what happens:

Main Board: (truly open, schematics and all) : http://beagleboard.org/ ($149)

Screen : Lilliput 8" 1024x768 touch screen (http://www.case-mod.com/lilliput-809gl80npct-lcd-touch-scree...) ($259)

Network : 802.11g wifi (http://www.usbgear.com/USB-Wi-Fi.html) ($30)

Battery: 7.4v LiIon 5200mAh (4 hours run) http://www.all-battery.com/index.asp?PageAction=VIEWPROD&... ($50)

Case: Injection Mold plastic (http://www.emachineshop.com/molding_machines/injection_moldi...) ($10)

Cost to build a single one, ignoring volume discounts and cost to assemble: $498. Being able to make one without a proxy (ie. using a supply chain company, design firm and manufacturer). : Priceless.

this is too slow, but it costs $6. http://www.embeddedarm.com/products/arm-sbc.php#ts-7800-seri...

What can you get for $50 worth of embedded mainboard?
