[Arm-netbook] will lap-top really be 1.1 kg, and how wide

[Chadvellacott]

I noticed that the campaign's main page on "Crowd Supply", says
"Only 1.1 kg weight" for the lap-top. Is this specification, still part
of the plan?

And how wide is the lap-top planned to be (from the left edge of the
case, to the right edge, across the key-board)? (I imagine that 15.6
inches is for the screen itself rather than the whole case, and is a
diagonal measurement.)

First, I don't represent Luke, but given what he has said in the past,

   I noticed that the campaign's main page on "Crowd Supply", says
"Only 1.1 kg weight" for the lap-top.  Is this specification, still
part of the plan?

I don't see why not, the storage drive isn't an ssd nor is it a hdd. 
Also the battery is not a 9 cell, a 6 cell or even a 3 cell. 1 cell.

Also, I imagine it has very few wires/components inside of it.

No wifi card or ethernet card instead it uses wifi adapter usb.

I guess my point is, I don't see why it wouldn't be really close to that
description.

   And how wide is the lap-top planned to be (from the left edge of
the case, to the right edge, across the key-board)?  (I imagine that
15.6 inches is for the screen itself rather than the whole case, and
is a diagonal measurement.)

As for this, I cannot comment at all. Luke did tell me once that it
would seem more like a 14 inch. At least that's what I recall anyways
him telling me. *(**I asked WAY TOO MANY QUESTIONS*!*)

*But yeah, unless someone else reponds and says otherwise, who knows
about the project I assume that's the answer you'll get.

kg weight" for the lap-top.

yes. no metal except that of the LCD (which i recall was 400g). no
SSD, no HDD, no fans, no heatsinks (except the metal of the keyboard
is in direct contact with the metal of the CPU Card case). it's a
good illustration of the "mass decompounding" effect, a phrase first
used in the vehicle industry.

And how wide is the lap-top planned to be (from the left edge of the
case, to the right edge, across the key-board)?

you can check for yourself by downloading the GPLv3-licensed 3D CAD
source code.
https://www.youmagine.com/designs/libre-hardware-licensed-parametric-laptop-design/

(I imagine that 15.6 inches
is for the screen itself rather than the whole case, and is a diagonal
measurement.)

the LCD is listed on the rhombus-tech page, from which the datasheet
may be sourced, and there is approximately 2mm left and right, about
10mm top, about.... 25mm at the bottom.

that gives the overall dimensions.

That page said "The parts are deliberately designed to be printable
on a standard 200x200mm Mendel90 style 3D printer, so that even a 15.6in
laptop may be created by printing the longest parts (260mm) across the
diagonal of a Mendel90 print bed (280mm)."
But I guess that 260 mm is not meant to span the whole back of the
screen, considering things lower down on this message.

Yes, the "youmagine"-page led to
http://rhombus-tech.net/community_ideas/laptop_15in/news/
to
http://rhombus-tech.net/community_ideas/laptop_15in/
to
"AUO B156XTN02.2" for LCD,
from which "duckduckgo" led to
http://www.panelook.com/B156XTN02.2_AUO_15.6_LCM_parameter_15249.html
which said
"outline size of 359.3(W)×209.5(H)×5.5(D) mm"
I did not get the "PDF"-data-sheet offered there, because I do not
have login-credentials there. But the quoted numbers are probably
correct, and are confirmed by
http://www.lcd-source.com/Product_Specifications_AUO_B156XTN02.2

359.3 mm width of LCD, plus 2 mm on the left, plus 2 mm on the
right, is 363.3 mm, or about

14.3 inches wide for the top part of the "clam-shell".

Thanks for the directing. That about answers my question.

that's the vertical.

case is thus divided into 7 separate parts for LCD and 7 main
structural parts for the body.

vertical @ 260mm

left
right
middle

horizontal @ 160mm (appx):

front left
front right
back left
back right

it's... complicated.
