ok, so in about 2 months i'll be doing a SMALL production run - absolute maximum of 20 units - of the latest revision EOMA68-A20 CPU Cards as well as putting together some 2nd revision laptop kits. it *might* also be the case - i have to check how many - that we have a sponsor (a 3d-printer company) for printing out the casework parts, primarily because these are exceptionally challenging parts and the sponsor would like to show that the quality of their printers is up to the task (which it is). certainly i am pushing the limits of the mendel90 which is in essence a significantly-improved reprap, as it is.
at this very early stage i don't want to go above 20 units just in case i have to do modifications by hand to the PCBs - which, if it becomes necessary won't be hard (with the 2-layer single-sided boards): i just don't want to have to spend that much time.
now, i'm *estimating* that the kits will be around the $EUR 400 to $500 mark, if we _can_ get to 20 then it may be less than that. i also have another sponsor who is prepared to buy some kits to sell, so that the per-unit cost can come down - we just have to see, based on who'd be interested.
so... who's interested?

I'd love to have one -- but you'd have to knock a zero off, which I know ain't gonna happen -- and with good reason!
Grumble grumble mumble I hate having no money grumble mumble grumble.

Isn't it enough to know that I have none of the first and precious little of the second? ;) Then again, there is such a thing as "too much" -- I don't fancy being at /either/ extreme...
$50 is one month's entire disposable income, BTW -- so it would have to include both goods and shipping. It would also leave me with no 'padding' for 'oops I didn't plan on dropping that' sort of issues... I could live with that, though, I guess. (Just continuing with the plumbing-grade reverie, BTW, I fully expect absolutely nothing to come of it.)
...meh, that's enough off-topic material from me for one day, I think.
I'm very keen. priority for my slot goes to devs but other wise ill very happy have one :D. Though I would need the laptop case, can pay extra for that. I assume its better to piggy back on the print job than to try to print it my self :) or at least it would be a lot more convenient for me :).
Software wise things are nearly there right?
Looking forward to the day of taking lots of photos of #ILoveEOMA heh

well i'll see how many we get, and we'll see how many the sponsor can do.

honestly it'll save a huge amount of hassle - you will however need to trim the parts [key files, scalpel] - there are underside supports that will need removing. the alternative is to use that water-soluble plastic as underside support, which also would save a lot of time.
example: i just printed the BASE_MID part at 0.1mm layer resolution: it just took 3h15m. the most extreme part (at 0.1mm layer height) is the BASE_BACK part (qty 2) which takes just over 4 hours.
those times can be pretty much cut in 1/2 (or more) by using 0.2mm layer height... but i found that the curving on the corners means that you then need extra time "trimming" to get them to fit together, whereas at 0.1mm layer height it's just a quick "swipe with the file".
on the new sponsor's 3d printers, it's highly likely that even "swipe with the file" won't be needed.
short answer: yes, saves a looot of time if someone else can print these parts - 0.2mm you're looking at around 8 hours, 0.1mm almost 20 hours.
Software wise things are nearly there right?
i've got working keyboard firmware - working being "if you don't type 200wpm it's fine". trackpad needs doing - it's possible to talk I2C. about a week's worth of software-writing there and it's all good.
micro-sd, usb hub, LCD screen, audio - demo'd well over a month ago, all working.
