This question must be looked upon as an overall one. Not
a concrete one. It is more about if you know about
the economics of these small netbooks.
https://edition.cnn.com/2010/WORLD/asiapcf/07/23/india.thirty.five.dollar.l…
I do not know if this computer got on the market. It
cannot be done for 35usd without subsidies?
Let us say we have a series of pc cards. Having different
performances. Various prices. According to lkcl the
cheapest would be about 30usd.
On https://www.alibaba.com/product-detail/Cheap-Via-8880-7-inch-Android_604789…
there is a 7 inch netbook for sale. It appears to be
a common computer. Prices are about 50usd.
I would want to compare the computer to the one
laptop per child. What magnitude of order would you
have to place at the manufacturer, getting him to
redesign the cabinet of the https://www.alibaba.com/product-detail/Cheap-Via-8880-7-inch-Android_604789… netbook to
become a pc card housing? What would he
be able to sell the pc card housing netbook
for?

It has a swappable solder iron head. The solder iron

I think the plan is to use the display the computer came
with. I would want to know which display model it is
I have. I have refrained from dismantling the
display part because it was already difficult to
remove the mainboard. The cabinet got some nicks.

I wrote 'Can lkcl' not 'arm-netbooks'. That was enough to ignite a
request from lkcl to change the phrasing of future posts from me.
I could have accepted the request. I did not because I
considered my phrasing short, effective and direct. I do not
see, why lkcl should limit my free speech on such a minor thing.
I should not have gotten the request in the first place.
Lkcl, is my phrasing that annoying or offensive or confusing
to you that you believe it is fine to ask me to limit my free
speech? Make your argument.
On this email list there is at least one person who dances with
profanities. I do not know if there is a rule about that. There
should be. I have not corrected that person for such
phrasings. For two reasons. It happens rather seldom.
And considering how it would limit the persons free
speech I refrained.

About the pyra's computer devices, do we know how well suited
they are to get connected to an eoma pc card?
My thought was to have a modified part of the pyra's cabinet
to enable inserting an eoma pc card.

For your information, I am in a censorship dispute with lkcl. I do
not know what he will come up with. Maybe some or all of my
posts will be stopped.
> Yep, thankfully, the laptop will likely take a while anyway. What I'd personally be interested in is making it all work before the start of next EOMA crowdfunding, or maybe during it (so that the crowdfunding gets some more publicity and is taken even more seriously).
When the pc card is being shipped there will be no cabinet
or a 15inch notebook available in terms of cabinets with
a display.
I agree the more different cabinet sizes present, even if
modified computer cabinets, the better. I do not
follow lkcl's opposition on this.
> I'm mostly interested in desktop sharing from my side, so that I can show how to draw a simple board.

Yes.

It is a weller sp 40l 40w.
In case I did not mention it before. I have a raspberry pi 0 and
a beaglebone black revision c if that could be useful.
> I've measured connectors on my boards, and it looks like the right one. Worst case - I can desolder a connector from my boards and mail it to you. Notes: from these 28 pins, one is GND (for some reason) and one is NC (not connected), and two pairs of pins are in parallel. So, we'll need a microcontroller with 24 free GPIOs, or a cheap I2C IO expander added. Seeing how the keyboard is a 16x8 matrix, a GPIO expander could fit very well (alternatively, we could copy whatever solution is used in some kind of popular DIY keyboards, provided we can find one that suits the row/column count).
I will get the ribbonconnector. I still have the asus eeepc's mainboard.
The pocketchip's keyboard is an i2c keyboard. Is the asus
eeepc's keyboard also an i2c keyboard?
Lkcl has said, the pc card supports i2c. Instead of
modifying the asus eeepc's keyboard into an usb
keyboard, what about i2c connecting the keyboard to
the pc card? To my knowledge you can use the
beaglebone black revision c to test i2c devices.
I found a video on youtube on the matter.
I have this forestalled remark. I would prefer not to cut
in the asus eeepc's cabinet. If I do it wrongly, I do not have
another cabinet.
Instead at the bottom of the asus eeepc there is a removable
plate. There is a balk which likely can be removed. I would
prefer to insert the pc card by that plate.
I have not been able to find something like the pcmcia/eoma
68 breakout board. Should we not find a shop to buy
one?
I will start a new post named 'asus eeepc 7inch, modifying
it to accept a pc card' for further postings.

Then I got the video wrong. I thought his listing of not open

fsf compliance.

I did not know. Apparently you then cannot buy a bag of

Hello!
The video of your FOSDEM 2018 talk titled
Crowdsupply EOMA68 Progress Report
is now available for review at:
https://review.video.fosdem.org/review/b9ee7bfb82b64e02220894c0b6c92587215c…
Please help us review your talk, so that we can release it sooner. This
will only take a few minutes of your time; if you don't do it, we will
have to, but then it may take several weeks or even months before your
talk recording will be released.
Things to look out for:
- Please indicate the start and end of your talk. Include our actual
talk, questions and applause. Optionally include the introduction.
- The review screen shows three videos. The video marked "main" is what
the system currently thinks is your talk. The two other ones provide
context. They should help you find the start and end points and will
not be part of the released video.
- Please verify that the audio track is usable. If it isn't, try the
"alternate" audio channel.
- In case of problems that you cannot fix using the interface, mark the
talk as "broken" and enter a note. We will then see what can be done.
If you want some more detailed instructions on how to use the webform,
please see the documentation at https://yoe.github.io/sreview

> If the pc card gets shipped, then I got one.
Great, I got one, too - so we can start the design, keeping a computer card in mind =) Rounded up all my EEE PCs and EEE PC accessories, turns out I have a box full of EEE PCs - got three 701s (one working) and one working 900 (basically, 701 with a bigger screen & slightly extended motherboard).

It's a hobby thing for me, too - it's just that I'm really interested in making it work, partly because I don't see why it wouldn't, partly because I'd like to build something new and interesting with EOMA68! There's even a chance I'll get so caught up with my other projects so as to never finish this one - while it's an unlikely outcome, it's still possible. I assume you expect the same treatment from my side - which is perfectly fine to me.

About large amounts of money - this project being expensive is unlikely, mostly because I don't *have* any large amounts of money to put into such a thing, so it will indeed have to be low-budget.
> We should do without time frames.
> Shipping the pc card appears to lay

Yep, thankfully, the laptop will likely take a while anyway. What I'd personally be interested in is making it all work before the start of next EOMA crowdfunding, or maybe during it (so that the crowdfunding gets some more publicity and is taken even more seriously).

I'm mostly interested in desktop sharing from my side, so that I can show how to draw a simple board. No other requirements from your side, webcam definitely not needed (though having a voice channel would be great). If you're interested, I can stream my desktop to something like Twitch, so that you can view it (and whoever else wants to).

I have no idea, I learned KiCad when I started drawing stuff. I think that something like "KiCad: Getting To Blinky" ( https://contextualelectronics.com/courses/getting-to-blinky/ ) could help with basics, a lot - it's a well-known KiCad tutorial.

Great! Once we'll have first boards (say, keyboard matrix), we might require some more tools - but nothing expensive or complicated. Do you have a photo of your soldering iron somewhere (maybe a similar photo on the internet) - just to make sure it's the right one for the job?

Oh, that's OK, and totally makes sense - I'm just starting to round up components, see what's suitable for us, and what isn't =)

I've measured connectors on my boards, and it looks like the right one. Worst case - I can desolder a connector from my boards and mail it to you. Notes: from these 28 pins, one is GND (for some reason) and one is NC (not connected), and two pairs of pins are in parallel. So, we'll need a microcontroller with 24 free GPIOs, or a cheap I2C IO expander added. Seeing how the keyboard is a 16x8 matrix, a GPIO expander could fit very well (alternatively, we could copy whatever solution is used in some kind of popular DIY keyboards, provided we can find one that suits the row/column count).
I've been looking at battery power solutions. EEE PCs use 2S LiIon batteries, meaning that usual PMIC like AXP209 don't fit. Thankfully, we don't need to do as much as AXP209 does (and the computer card has an AXP209 in it anyway). For a start, we need to charge the battery, have some kind of signal when charger is present, optionally, step down the voltage to 5V. I've found AXP259, which does all three and should fit. I'll ask for a sample - I don't expect it any soon though, it's Chinese New Year, after all. I wonder if they'll even send a sample - I guess I'll purchase a couple of these in parallel, just in case.
Cheers!
