USB3.1 pinout
by Internet 06 Feb '17

06 Feb '17

Hey there! I was wondering about the USB3.1 pinout in the EOMA68 standard. In my research on the USB Type C connector I found out that USB3.1 (Superspeed+) has only two differential signal pairs (one for receiving, one for transmitting) but on elinux.org there are four differential pairs for only one USB interface. Are the other two pairs meant to be used by the second USB port or did I miss something? Thank you very much! Julius Lehmann

Here is my attempt at a KISS logo for EOMA68 (easily adapted for other standards): https://www.flickr.com/photos/151565999@N03/32579869145 If you want me to post it somewhere else (or you want the sources), you got to point me where to upload it.

I hope I am doing this right subject wise, I am curious: I was wondering how much battery life do you expect to see by default if you have a web browser like firefox open. I also wondered when the 4gb ram supporting processor will be an option. Is the printed for you version easy to build? and finally I am curious, is it extremely stable? just because it is made partly of wood that makes me curious. fire problem aka...

KDE Slimbook
by David Boddie 28 Jan '17

Wandering off-topic again, it seems that a KDE laptop has been announced: https://dot.kde.org/2017/01/26/kde-and-slimbook-release-laptop-kde-fans It's Intel-based, so not interesting for everyone here, and more of a power user's laptop: http://kde.slimbook.es/hardware KDE Neon is based on Ubuntu 16.04 at the moment so, again, maybe not to everyone's taste, but another option for some people, maybe. Not sure about the choice of name myself... :-p David

personal fight against the modern laptop
by mike.valk＠gmail.com 27 Jan '17

27 Jan '17

http://hackaday.com/2017/01/26/a-personal-fight-against-the-modern-laptop/ https://youtu.be/Ib7tFvw34DM I Commented on the video that EOMA might be what he'd like. I tried to point him to the EC firmware but "http://hands.com/~lkcl/eoma" is bit of a mess. It contains a lot of (historical) info without structure. Also I find. http://rhombus-tech.net/community_ideas/laptop_15in/ and the e-linux wiki hard to navigate. It's messy. If I'd like to start hacking on the laptop a staring point would be nice.

EOMA68 In A Intel Card World?
by Alexander Ross 27 Jan '17

27 Jan '17

How to market eoma68 vs intel card in a positive way? Heres a go, please edit,suggest as you feel. hmm sounds like a wiki page is coming :) : EOMA68: *Grass roots developed - made by someone who cares *Any processor make *Made with free software and its developers in mind. to help advance and fund free software. *Hardware that just works for free software and there for any software *Makes it easier for the creation and maintenance of many, yet to be thought of, new devices. *Higher Spec additional standard EOMA200 in the works after current ones products are in the market. *Smaller, extra compact card Spec, EOMACF addition also on the future list. *Only certification fees. No royalty fees *Made by for profit making but good will first company, as opposite to extreme maximising company. The priority is the best computer card standards. *EOMA68 is spec’ed for lower power consuming devices. ideal for battery power devices. See future EOMA200 for high power consumption / more powerful computers(SOCS) *hmm what else?

What's the current status of things?
by Christian Kellermann 24 Jan '17

24 Jan '17

Hi Luke! I would like to ask how things are working out on your side of the world with the EOMA68 project? How's the production planning? I have heard snippets of information spread out over all the threads here, a short summary would be awesome! And I guess it might be of interest to others as well, so this humble request goes to the list. Thanks, Christian -- May you be peaceful, may you live in safety, may you be free from suffering, and may you live with ease.
