L.S.
Just put some thoughts to paper.
Just a mock-up, nothing thoroughly engineered
Notes: 1. Make the battery exchangeable. 2. Reuse cheap cellphone batteries (mass produced) in adapter sleeves. 2. Make the network interface exchangeable. 3. Make adapter sleeves for the most common cellphone batteries.
Some benefits: - Batteries have differing lifespans than screens/cpu's/network systems. - Battery technology evolves rapidly. - Every new cellphone has a different battery format. Cheap sleeves can be made to accommodate the cheapest available battery. - Wireless/Wired network technologies are abundand and evolve rapidly. - The wifi dongle can be exchanged with a wired variant - The wifi dongle can be exchanged with an new network technology bg/n/ac 5ghz channels etc - The wifi dongle can be exchanged with an roaming network service, 2G, 2.5G, 3G, 4G. - The wifi dongle does not need to be pre bundeled. User can choose his/hers own - The wifi dongle can be exchanged with a usb camera low or highend
The bottom USB slots can be used as a connector for charging stations, docking stations, keyboard docks, dual screen, etc.
P.S. It's been awfully quite around here.....

not bad though. what you got that in - blender?
i kinda like it. it'd have a deliberately chunky feel, easy to hold. thickness would be around 12mm, unless you left the back of the CPU card exposed (then you get about 2mm back).

... and all of those, being rather power-hungry, if the battery is interchangeable as well then that's absolutely fine because people can consider carrying around a 2nd battery. or get an "extended" one specially for those circumstances.

yeah i know. we need people to place orders for CPU cards. and quickly.

this from max speransky, way to go max! (remember you need to send from a subscribed address - this bounced but was cool enough i thought i'd send it on manually).

Interesting topic raise, i'm new to list but also have my own vision, how EOMA-68 can be used. Even made physical scaled prototype ) Here is a link to github, there are SCAD design sources, ready for 3d printing, https://github.com/idepositbox/thecan
Still in evaluation phase with investors, so no actual orders just poking around various designs.

max i thought i'd point out that i spotted an 8-shaped power socket on the drawing - is that mains? if so unless there's a really good reason i'd recommend having a separate power adapter, there's a very good power IC that does up to 4A anywhere between 7 and 21V DC input. power adapters are a pain, and also you have to take extra-special care on the design of the PCB as well as consider safety issues.
also if you're doing this as an open hardware project i'm happy to do the PCB design if you like. it'd be with PADS because that's what i can use, and it's very very good, plus i have a large library of parts now.

Sketchup, Have not made that many flight hours in blender to be fast enough.

Well I made a "window" gap. So you can see which card/battary is in it and to help with heat dissipation

Did you mean the generic Wifi sticks or the cell-service sticks?
Because for the EOMA card we have to stick with the usb-wifi either externally or internally.

I had the idea lingering for weeks and finally found the time/energy to put it work. So buying an eoma card is not really beneficial to me or you, other than funding, at the moment. And I can afford to buy it as shelf filling at the moment.
How about promoting it on the Sunxi mailinglist/wiki. They sprouted from here so why not?

awesome. that puts the thickness of the device somewhere around the 10mm mark.

both. they tend to be around the max end of the 0.5A limit.

as discussed before, they're running on proprietary mailing list software that requires registration that is unacceptable to me, and incompatible with the project's ethics, so i cannot do that.
... however there is nothing to stop anyone else from doing so.
