eBay has a bunch but they're all cheap nasty Chinese Bluetooth jobs.

My post was inaccurate phrased.
I should have written a wired usb keyboard, touchpad may be attached, having a width about 15cm.

be attached, having a width about 15cm. The bluetooth keyboards
do not have the option of wired usb?

The Bluetooth keyboards are Bluetooth only.

Wired USB keyboard, that size? Never seen one. Would love to have one
myself; I've wanted to homebrew a waist-pack PC with wrist keyboard and
"google glass" style screen, since approximately a half hour after the dawn
of time. I've even got a viewfinder CRT out of an old camcorder that I
could use as the display if I hooked it up right. Trouble is I don't trust
BT to not interfere with everyone else and screw me up too... that, and I'd
need to make it work with a battery.

Now that I think about it... I think I've seen one such keyboard literally
once ever, either by luck on eBay or on some other website. Don't remember
since it was at least five years ago. The thing commanded a princely sum,
too... like $150.

It occurs to me as well that you might be able to get an
industrial/commercial duty wrist PC off eBay (be prepared to pay multiple
hundreds of dollars) and doof around with its built-in keyboard... or do
something with part of a cell phone and a Teensy... but that's real
jerry-rigging at best. There are also keyboards floating around for old
IPAQ PDAs that may be useful somehow... but you'd have to reverse-engineer
them and they look like they'd be horrible to use to begin with, you don't
even get most PC function keys (TAB, CTRL, ALT, etc).

Good luck, and let me know if you find one...

so that's 2 dead-ends... so far.

keep going, ron. you'll only really start to understand how
difficult this really is only by persisting until you *succeed* in
finding what you want. or trying a different tack. or several.
until you succeed.

and this is just one component out of the dozens that you'll need to
source in order to complete the proposed conversion of *one used
laptop*.

i believe the record so far for finding the correct (suitable) part
for the EOMA68-A20 stands at five years. it's the mid-mount
micro-hdmi (type D) connector. JAE DC3 series.

... are you beginning to get an appreciation for the perspective
that, from an ecological standpoint, spending the time and energy on
"converting" pre-existing mass-volume-designed products is an
extraordinarily wasteful use of our planet's resources?

this was the main unspoken message of that ted talk "how i made a $3
toaster for $1800 and took a year to do it".

I am not sure if you like this idea, but making a usb wifi adapter in an
eco and libre way.

aka within an eoma standard.

My only reason for suggesting this is that libre ones might become
scarce eventually and you have enough talent I bet to make a very strong
yet still lightweight though.

By strong I meant like 450mbps and very lightweight is what I meant by
lightweight.

I am giving this thought to you, because you are thinking of making a
router why not a usb wifi adapter too as well?

This would be something far off I imagine though. but its a thought I
wanted to throw out there.

Tell me what you think Luke.

funnily enough i was looking to source AR9271 ICs and a reference
design to be able to mitigate the risk of the AR9271 becoming less
common (which it already is, due to atheros/qualcomm's new management
not quite understanding why ath9k was so popular)

no - USB already covers that adequately.

Promising! but as Christopher mentioned, "This item is Discontinued".

I had luck searching for another 56 key keyboard ("50%"?): USD $23.73

http://www.dx.com/p/mini-56-key-usb-keyboard-with-retractable-usb-cable-for-pc-and-laptops-15953
http://www.dx.com/p/15953
http://www.dx.com/c/computers-tablets-networking-399/keyboards-302/USB-351

The X/Y dimensions are very similar, though it's 60% heavier and 5mm thicker.
Dimensions: 6.69 in x 2.91 in x 0.79 in (170 x 74 x 20 mm)
Weight: 6.53 oz (185g)

I think I'd miss the dedicated arrow keys.
I'd like it even more if it had an integrated trackball or trackpoint,
which I guess requires a USB hub device/emulation as well?:

Good find. It looks to be the same keyboard.

That would make it much easier to integrate it in a pc card cabinet. I have
searched for wired usb touchpads and trackpoints.
I have not found any.

Nick.
I have bought one 7usd bluetooth small keyboard. It
appears to have a touchpad too. I cannot say how
difficult it will be to modify it to a wired usb keyboard.

There is the Loading Image...
cabinet. If the 3d printer cad files are free software.
