it's kind of fun watching the mailing list switch from SoCs, through software, PCB design and now to hinges
<L84Supper>
and still no hardware :)
ganbold_ has quit [Remote host closed the connection]
ganbold_ has joined #arm-netbook
<penguin42>
but not I know where to buy a hinge for a boring normal laptop
<L84Supper>
ebay
<L84Supper>
people have complete tooling for laptop cases gathering dust that you can buy for the cost of scrap
<L84Supper>
or you can even SLA print entire custom cases in a few minutes for ~$1ea in polymer
<mnemoc>
o_O
<penguin42>
L84Supper: Which for the scales for this project are possibly best
* penguin42
didn't realised you could get 3d printing done so cheaply/usefully - most 3d printing I've seen is frankly useless
<L84Supper>
yeah, you have to ignore reprap and the other 80's tech
<L84Supper>
but the world would be boring if there were't reprap printed RPi cases or attempts at making bamboo laminate enclosures
<penguin42>
some of the laminate stuff is interesting - the laser cut laminate hinges are great
<L84Supper>
print glass forms for the bamboo to grow into, slice and sand
<penguin42>
haha
<L84Supper>
even better 4 different glass forms with the snap-fit molded in, grow the bamboo into them, harvest when ripe and assemble
<L84Supper>
you could 3D print a paste with bamboo pulp or use bamboo dust and print a binder
<lkcl>
L84Supper: that's not true!! and remember, it took a hell of a long time to find the specialist parts and suppliers. the A10 board's done, we've got another 7 samples on the way. the flying squirrel's on its 2nd revision PCB, casework in progress.
<lkcl>
there's a *lot* going on - so much that i don't have time (with a full-time job) to tell everyone what's going on
<penguin42>
L84Supper: I bet you eat square oranges don't you?
<L84Supper>
just ignore me, lkcl
<mnemoc>
lkcl: what about the laptop part?
<penguin42>
lkcl: You have to admit that there isn't much hardware
<L84Supper>
combining a bamboo laminate with bamboo dust+binder would be really strong
<penguin42>
even if it's a lot closer
<L84Supper>
not very heat conductive though
<L84Supper>
PVA for a binder mixed with graphite would be heat conductive, but the color might not be what you want
<penguin42>
and water soluble?
<L84Supper>
yeah, unless you seal it
<L84Supper>
but it would be easily recyclable if it's water soluble
<L84Supper>
maybe coat with a nut derived epoxy and nutshell powder slurry, then it would break down over time in UV and only rot internally after getting soaked
<penguin42>
youre ideas for 3d printed stuff is very odd!
<penguin42>
at this rate you'll be making an edible laptop
<L84Supper>
or just buy somebodies old tooling for a few $K and make some inserts for the card
<L84Supper>
possible
<L84Supper>
sugars and starch
<mnemoc>
tasty
<L84Supper>
candy molds are cheap
<L84Supper>
could be 99% edible if you coat it
<penguin42>
but would it be able to hold any open sauce?
<L84Supper>
like a sauce tray in a Happy Meal?
<L84Supper>
I guess it would be possible to 3d print a scaffold that would serve as the enclosure that skin cells would attache themselves to...
<L84Supper>
grow a thick enough layer and let it dry
<L84Supper>
or maybe nail cells, then it would be a hard shell
<penguin42>
yeuch
<L84Supper>
it's just not very fast
<penguin42>
'Warning: Laptop needs feeding, please insert dougnut and hit return to continue'
<L84Supper>
it could live off whats left on the keyboard after a bag of Cheetos or even food was consumed
<penguin42>
way too slow, I can eat them faster than it can print them

penguin42: if we wanted "just hardware" we would have just got any old laptop, any old tablet, any old desktop product designed by any old china knock-off factory.
tzafrir has joined #arm-netbook
<lkcl>
you saw how easy it was for neal to create the pengpod tablet? all he had to do was buy any one of *literally* thousands of china knock-off tablets.
<lkcl>
how hard is that?
<lkcl>
this is completely different. it takes weeks to get it through chinese factories thick heads that we DO NOT WANT THEIR CRAP KNOCK-OFF PRODUCTS.
<lkcl>
one day, if i get permission, i'll publish the conversations from one of the factories.
<lkcl>
"we have a tablet, how many you want buy?"
<lkcl>
actually we'd like a redesign, according to our specification
<lkcl>
"i understand. how many of our tablet you want buy?"
<lkcl>
errr no... we give *you* the design, you make it for us.
<lkcl>
"ok, we give you our design. how many you want buy?"
<lkcl>
err... no, that's *our* design, here's the specification.
<lkcl>
"ok. our engineers will study it."
<lkcl>
thank you.
<lkcl>
"our engineers say there is no processor, it cannot work"
<lkcl>
that's because the processor is on a CPU Card.
<lkcl>
"ah. we look at that too. our engineer can redesign! the A10 is great!"
<lkcl>
yes, but we want it done *our* way, not yours
<lkcl>
"our engineer say your way is old-school. we can do it better! cheaper!"
<Undertasker>
Same thing happens with engineers from India.
<lkcl>
Undertasker: amazing, isn't it. and each time there's a 48 hour delay
<lkcl>
i haven't even got to the arguments about how they can do the software better, yet!!
<Undertasker>
You tell them 10 times exactly what you want, they always say ok, but don't understand a word
<penguin42>
the guys from India and China aren't all fools - it sounds like you're talking to guys who want to either save money or get you to pay up for design services
<lkcl>
Undertasker: it's incredible training in patience
<lkcl>
penguin42: true. franson's smart. the problem there was finding a client willing to pay his up-front fees.
<lkcl>
mostly this is about getting at least the engineering costs paid-for.
<Undertasker>
I didn't say they are fools, but it seems that they are too afraid to ask questions, or admit that they don't understand what you want
<penguin42>
lkcl: I don't really understand the need to redesign the mechanicals though if you start with a base that has a PCMCIA slot
<Undertasker>
They rather say, ok, I'll do so, and then come back with a solution that has nothing to do with what you told them
<lkcl>
the issue here is that we have to tackle - and redesign - *every* product
<penguin42>
lkcl: I guess the challenge is finding a modern looking chassis that has a PCMCIA slot
<lkcl>
penguin42: every laptop that has a PCMCIA slot is designed for standard x86 laptops. they're at least 15 to 20mm thick in the base part, in order to accommodate keyboard, PCB, fan, heatsink and processor
<lkcl>
penguin42: yeah exactly - there aren't any. anything with a PCMCIA slot is at least 8 years old.
<Undertasker>
Older. After PCMCIA came PCCARD
<Undertasker>
Same connector, though
<lkcl>
Undertasker: PCMCIA is PCCARD. People Can't Pronounce Computer Industry Acronyms
<penguin42>
haha
<Undertasker>
No. PCMCIA was 16 bit, PCCARD 32 bit. Also you can't put a PCCARD in a PCMCIA slot
<lkcl>
so they changed the name. made it 32-bit
<lkcl>
oh ok ok :)
<Undertasker>
They don't fit, because the changed the plastic edges a bit
<mnemoc>
ow
<lkcl>
Undertasker: yes.
<lkcl>
Type I and Type II
<lkcl>
now. i was going to look something up...
<Undertasker>
I still have network cards of both types here. Don't know wy I keep them
<lkcl>
:)
<lkcl>
i have two sitting on my desk. actually my mum still has a laptop that needs PCMCIA wifi.
<Undertasker>
When the PCMCIA ethernet card was manufactured, there wasn't even wifi
<lkcl>
ethernet card dongles.... grrrr :)
<Undertasker>
I still have a parallel port 10Mbit Ethernet adapter somewhere
<Undertasker>
Takes power form the PS/2 port
<lkcl>
aw my gawd. you thinking of opening up a museum, or what??
* penguin42
throws a AUI block at Undertasker
<lkcl>
s/Pronounce/Memorise
<Undertasker>
Well, for the low end/low cost side of the hardware we now have Raspi and Android sticks. So it may be time to get rid of the old junk
<Undertasker>
I'm just too lazy, and my barn is big. :-)
<lkcl>
Undertasker: burn it, yeah!!
<penguin42>
Undertasker: Want a couple of Sun3's to keep it warm?
<lkcl>
solve several issues at once. save on heating bills, get rid of the junk....

<lkcl>
wow.

<Undertasker>
Don't know. It hasn't been powered up since 30 years or so

I must have a Sinclair ZX81 somewhere.
<Undertasker>
But not in the original housing
<lkcl>
Undertasker: bloody hell, those are valuable. awww, darn. no case?
<Undertasker>
Had put it in a bigger one and added a real keyboard
<lkcl>
:)
<Undertasker>
The damn thing wasn't usable with the original "keyboard"
<Undertasker>
Well, to be honest, the whole thing wasn't really usable
<Undertasker>
The smal processor did the video signal generation by software, so there was nearly no computing power left
<Undertasker>
It had a turbo mode where it switched off the video, though
<lkcl>
Undertasker: i was "lucky" enough to have access to a ZX80 (with a ZX81 ROM upgrade).
<Undertasker>
But it was the first home computer below $1000
<lkcl>
that _was_ awesome. press a key and the screen (TV) would go "snow"
<penguin42>
well I was trying to make that joke :-)
<Undertasker>
I must have some Mini PC's somewhere. 8086 and 80286
<Fragmint>
286 blows it away. =(
* mnemoc
had 8088 and 8086... but not precissly "mini"
<Undertasker>
Was thinking about placing a Raspi and a 2.5" disk in one of the housings. The power supply is still good
<Fragmint>
screen stll works up andi tt boots bu the floppy drive won't read disks. =(
* Fragmint
smashes his keyboard
* penguin42
hands Fragmint one of his spare 5.25" drives
<Fragmint>
=O
<Undertasker>
And maybe the upper lid is big enough to hold a 10" tft module. This would make it nearly a raspi notebook
* Fragmint
hands penguin42 a waffle
<penguin42>
oooh
<penguin42>
Fragmint: What's that thing to the right just below the black bit?
<Fragmint>
#<('_'<)
<Fragmint>
lets you tilt the screen in/outtt
<penguin42>
oh weird!
<penguin42>
it's kind of silly what you could get in a chassis that size these days
<Undertasker>
100 Arm cores, or so
* penguin42
bets you can beat that a long way in that size
<Undertasker>
Cores are small nowadays. I talked to a microcontroller manufacturer. They are just shrinking to 22nm, and they told me that in fact the number of cores doesn't add much to the cost. RAM and Flash do.
<Undertasker>
They sell micros with 6 cores, but could easily add more, should we need them.
<penguin42>
yeh the area of an ARM core is tiny
<Undertasker>
32000 gates for an M3
<penguin42>
yeh it'll be a heck of a lot more for an A series I guess, especially when you put the cache on; 4KB of cache would be what 4x8x6+a bit - 200k transistors without the core
