well,
i must apologise to everyone, the effect that the situation with aaron has had on my associate is more severe than i thought, and that is actually a *good* thing rather than a bad one.
the original goal - which is at the very top of the rhombus tech web site - is the one that i wish to see happen. my associates it turns out wish to make money as the absolute sole exclusive top priority and they are prepared to sacrifice all and everything - principles, ethics, relationships and more - in the pursuit of that absolute pathological goal.
so the first thing that happened was that the rhombus CIC was shut down without my being informed. the second was that i was signed up as a Director of QiMod Ltd without my signature, then removed when the situation with aaron occurred. in between, the idea (suggested by aaron) was floated to use trademarking to protect the EOMA concept (and more importantly the end-users from being harmed) by mis-implementation.
i've now received demands for cash up-front license fees for the EOMA concept that *i designed*, when i was planning to work profitably *with* the very people demanding those fees.
this basically means that the very principles that i founded the original goal on [to bring together software libre developers with mass-volume hardware manufacturers at every stage of the product process in a mutually beneficial way] are being _completely_ violated by the associates i thought i could trust to help make them happen. so, aaron, thank you for helping to create a situation in which i found that out now, rather than later.
so i'm now at a major decision point... but let me be absolutely clear: i *will not* be sacrificing any principles or ethics, and i *will* be carrying on the goal. i will be making one last attempt to make this clear to my associates over the next few days, but if they cannot understand how important those principles and ethics are then i will be forced to carry on without them.
last but most important thing to say for now: to the people who have donated money over the past couple of weeks, if you would like it refunded now, please let me know.
l.
Unfortunately, none of this is very surprising once money enters the equation.
I think what most people want to know is what does this mean for the designs and eoma concept? (The name/trademarks are less of an issue given that the project has not taken off.) If the designs can be used and more developed (modulo a bit of legal sabre-rattling), I don't see the problem.
As an aside, is there genuine private interest in the eoma concept and your associates are trying to drive you out? Or are they just bonkers? There is clearly not the slightest dollar visible in this project at the moment and their actions seem designed to strangle it at birth.
Best,
Boris

it's a little stranger than that, as we've been working commission-only basis for 4 years quite happily, and i've known my associates for almost a decade now.
I think what most people want to know is what does this mean for the designs and eoma concept?
well, i designed them all: i never signed anything which *explicitly* handed over the copyright of the designs. i also own the copyright on the *text* of what is on the elinux.org web site, which is as you know under a creative commons license.
(The name/trademarks are less of an issue given that the project has not taken off.) If the designs can be used and more developed (modulo a bit of legal sabre-rattling), I don't see the problem.
me neither. my associates won't like it, but yes. just as bari said (ironically) it's just a physical interface.
As an aside, is there genuine private interest in the eoma concept and your associates are trying to drive you out? Or are they just bonkers?
baislcally he is so embarrassed by the [joint!!!] decision to trust people associated with the software libre world that he considers the whole concept to be more than pointless but actually *detrimental* to the "business interests of qimod" to allow it to continue.
he therefore wants to turn qimod into a "simple and clear boxed product" company, selling Intel NUC-style branded designs.
There is clearly not the slightest dollar visible in this project at the moment and their actions seem designed to strangle it at birth.
yes, because it is quotes embarrassing quotes to be associated with software (libre) developers, because, in his view, they are all completely incapable of handling basic business transactions or delivering on their business promises.

Maybe it is worth taking stock. At this stage the project will probably benefit from some clarity as to how much mischief your (ex-)associates can make.

So they probably don't own the copyright to the designs (some of which are gpl'd?) or the text, which seems to include the specification. Presumably that text counts as prior art if anybody tries to get clever with patents.
So that just leaves the trademark? A new name is hardly the end of the world. If it's definitely required, just get it over with*. However, maybe your associates should realise that all over the web "eoma" is associated with long-haired, sandal-wearing freetards and it would really be in their interest to change the name of their system to something new and shiny.
If your associates actually end up making some hardware that runs free software, that's probably still a good thing. If the systems remain compatible, then that's also a good thing. If not, good luck to them.

* Modular SOC: MOSOC. MOSOC-68? (Goodle doesn't seem to find an obvious clash.) Or maybe Ice-something?
I suppose this is very bad news.
If you do not reach an agreement with your associates, will the EOMA-68's project be canceled?
Thanks.

Why dont you register new trade mark, change this slightly and continue? If they have patent only on trademark they got nothing to hold you on technical side of the card (that you in fact developed and that is worth something at least in my mind). Also, trade mark without a commercial basis is worth nothing and you dont have one, yet. I really see no problem for you. Maybe from ethical point of view from ppl your worked with but not from the point of company.
Namely, we registered some patent recently and I found out that ppl are not understanding difference between trade mark and patent. Also, there are two kind of patents and substantive examination patent is the one that you can protect your technical solution fully and that one is tougher to deal with but probalby you (or somebody else) will never be able to get this kind of patent as it is really nothing new in your work. What is valuable is your work itself and trade mark really not problem for you.

it cannot be called EOMA because it is trademarked. i have no intention of giving up on the goal stated at the very top on the rhombus-tech web site.

And now you begin to wonder what I meant when I said the pole was greased from two different directions:
Wed, 4 Jun 2014:
Rest easy. Pressures being what they are from the subversive Bill Goatse's of this world, have to plan. Greased the pole from two directions with fully GPL'd sub projects already! :)
http://www.gplsquared.com/SoM2/SoM2.html alternative in full KiCAD should failure became an option for whatever reason. Anyone can run with alternative should they see fit.
http://www.gplsquared.com/eoma_boot/eoma_boot.html the Linux images are interchangeable with cubieboard2 so developers can continue even if EOMAs are not physically available to hand.
The final jigsaw is a fully GPL'd openscad based case designs for tablet, netbooks, panel computer, and match box sized gadget. Got me four 3D printers to address that soon enough.
(Robust fully GPL'd applications have also been pencilled in though those require a lot more free time to get things going at this moment in time.)
FYI, I got costs - about $50 for EOMA-68 with the 2GB RAM and extra FPC connector but that comes with a 2000 MOQ lead balloon for the PCMCIA case because those cases are not made in China - they are made in Taiwan. Ping off list for details.
So, Aaron/Luke, et al, stop trolling us with your sad stories of losers stealing all your money. There is plenty of money and resources around for this project. Just need to ask. Just need the focus to get it together into working projects. That be why my handle on #arm-netbook is "focus". If an EOMA can launch with KDE plasma, then as a company we could certainly use it which is were all my focus is on at present. (For me, its the time that I'm short of to help out with.)

Two things, that I'd like to contribute.
A new-name suggestion, if it comes to that...
"Open Modular Card System", stylized "OMCaS". (Pronounced AHM-cass) It's, from what I can tell, a fairly accurate descriptor, and the acronym is fairly catchy.
...and an idea for further expansion. Rather than have a single CPU card that plugs into a carrier board with lots of stuff, why not have *multiple* cards -- both as the "motherboard" and as the expansion cards...? ;) Key them differently, and then all you need is a mostly-passive backplane ("mostly" because it would obviously break out some of the ports) and a pile of Cardbus connectors.
What do you all think?

hi chris,
lots going on here, very briefly i'd like to share an idea which is inspired by the HTC Universal phone and it could do with modernising. we never identified the chip name, we called it "ASIC3" but it was basically an I/O break-out IC, with 32 GPIOs, 2 UARTs, 3 SPIs and more besides. it was memory-addressable (so just like NAND flash ICs and the DM9000 Ethernet IC).
what we are missing in the modern low-power embedded devices world is the equivalent of this IC with more modern interfaces (extra USBs, video screen outputs and so on) a kind of low-power embedded equivalent of the AT/XT/PCI backplane concept on which, chris, your idea is somewhat dependent.
my feeling is that there should be a market for an IC that is USB3-based which has a stack of functionality such as GPIO, A/D, DAC, PWMs, USB2s, SPIs, SD/MMCs and even an RGB/TTL and other LCD outputs. apart from being only USB2-based, some of ATMEL's embedded Cortex range _almost_ qualify *on their own*, and ICubeCorp's IC likewise might almost qualify as it has enough CPU horsepower to do decompression of LCD output data to fit over a USB2 bus.
anyway. i read what everyone has been writing, i have to absorb, think but not too much, focus on the contract i'm doing, keep doing the PCB designs, and wait for responses from my associates, see if they come around.

The easiest option for me then is to take one of a numerous number of tablets I got, strip it down and do an openscad parametric design and release it fully GPL'd after making sure it can be 3D printed. Anyone can then make their own cases. The reverse side will be split into two like a pair of shutters. The shutters are interchangeable - make one a keyboard, and the other a flat wireless charger coil. Alternatively have both replaced by solar cells. I already purchase the solar cells (0.1mm thick and damn fragile!). All parametric so any size ARM netbook/tablet screen size, bezel size, battery size ready to accommodate and print.

there are parts inside. it is very easy to make a case where the parts don't bloody well fit.
for example the battery compartment is the wrong size. the hole for the camera is in the wrong place. the connector for the touchscreen can't fit because there's bloody well bits of plastic in the way.
is that clear now?

great idea. can you use pyopenscad rather than direct openscad?
if you need complex 3D bezier-specified sheets i wrote some code which auto-generates them (and it's in python.) http://www.thingiverse.com/thing:13899
you specify a list of lists of points, tell the function how many intermediate points you want and it will use first a run of spline curves on each individual array then do a *second* run cross-array.
end result is that you can do very sparse spec'ing of a complex 3D shape and it will generate a smooth 3D sheet that fits exactly through those points.

Nope. Verbosity makes things unclear.
If things don't fit, I change parameter and print again. Its parametric. Two three iterations, and job is done!

If things don't fit, I change parameter and print again. Its parametric. Two three iterations, and job is done!
yes... but you have access to a 3D printer on a fast cycle. the internal 3D layout of all components *had* to be done as CAD/CAM because we did *not* have access to a 3D printer on a low-cost fast iterative cycle.
The easiest option for me then is to take one of a numerous number of tablets I got, strip it down and do an openscad parametric design and release it fully GPL'd after making sure it can be 3D printed.
great idea. can you use pyopenscad rather than direct openscad?
Probably.
it's pretty obvious, object-orientated and if you can handle openscad directly i think you can handle pyopenscad. it actually outputs openscad files so that way you can see what is going on iteratively.
end result is that you can do very sparse spec'ing of a complex 3D shape and it will generate a smooth 3D sheet that fits exactly through those points.
Snap! Funny thing I needed exactly something like that for various projects.
the only (current) limitation is that the "offset" for creating the 3D shape is a *fixed* vector. by that i mean that rather than specify the "thickness"and do some normalised vector calculations at every single damn point created, what i did was *copy* the surface that was created, shift every single point by the fixed vector then create edges around the sides to join the two surfaces up.
the down-side of that approach is that if there is extreme curvature in the surface being created the thickness will end up varying or possibly even be zero (or overlap) creating an invalid shape.
at some point i will revisit the code and work out how to create the best "rangle" between each of the 3 to 4 vectors coming in to a single point. it's harder than it sounds because sometimes they could overlap.

if you need complex 3D bezier-specified sheets i wrote some code which auto-generates them (and it's in python.) http://www.thingiverse.com/thing:13899

oh bollocks that's cos i deleted my github account because of their policy. ok grab this: http://lkcl.net/pyopenscadspline.tgz

Tried it this morning - not working either.

ok i'll get to the permissions on it this evening.
