I would be glad to find something compatible, but shaped like N900's SIM holder, to avoid tearing it apart if pins happen to break again.
<DocScrutinizer05>
err, N950 is slot-in
<DocScrutinizer05>
odds are Nokia used same type they already had on stock, so I'd say "test it"
<Oksana>
Ok... In appearance, it's very close, but not exactly the same. Are there any electrical pins for SIM-holder, besides 6 SIM-pins? Or are all other solder-points just for stability of holder on the board?

worst case it's soldered and you need to clean the pins with soldering iron from flex copper trace remnnts before soldering it to N950
<Oksana>
I do have soldering iron available, fortunately. How do I clean the pins from flex copper trace? I wish they had documentation on differences between 14011V2 and 14191V2.
<DocScrutinizer05>
cleaning is simple: wipe the contacts clean with soldering iron and a tad of fresh solder
<DocScrutinizer05>
you can even use steel wool and wipe the hot contact and molten solder with it
<DocScrutinizer05>
gently
Kabouik has joined #neo900

but usually not needed, any dirt and debris will come off and stick to the soldering iron tip
<DocScrutinizer05>
it's way simpler than it sounds
<Oksana>
Okay. Just trying to hunt down suitable (for N900) microUSB port-connector from same seller, to have them shipped together.
<DocScrutinizer05>
those shouldn't cost more than max 50ct per component
<DocScrutinizer05>
btw the new schematics still are not "fit for primetime", there's still quite a few things that need to get fixed or finalized before we even could start thinking of layout
<wpwrak>
speaking of "finalizing", shall i make a TLV1702 (dual op-amp, as used for ECI) begin to appear in IR ? :)
<DocScrutinizer05>
not yet.

speaking of bare PCB scans and such, it may be nice to have a public page that organizes the links to all the various public resources nicely. those scans, the "3D" scans, the IR white paper, schematics, things like issue tracker, maemo hardware pages, elinux.org, bootloader_project, etc.

now for step two, which is a college degree stuffed with absolutely nothing at all, errr which would be TMC over IP then
<DocScrutinizer05>
I guess they thought a simple telnet connection to talk TMC to the scope was was waaaaaay too obvious and simple
<DocScrutinizer05>
hmm TMC is USB-specific
<DocScrutinizer05>
:-(
<kerio>
stop saying "telnet" when you mean "raw"
<DocScrutinizer05>
probably they implemented USBoverTCP for the Rigol's network jack ;-P :-(
<kerio>
telnet is anything but raw
<kerio>
it can't send bytes over 127, for fuck's sake
<DocScrutinizer05>
oooh, good point
<kerio>
(without negotiating for it)
<DocScrutinizer05>
well, TMC is not the protocol of choice for TCP/IP anyway
<DocScrutinizer05>
I rather should check if LXI has some words on protocol via network
<kerio>
DocScrutinizer05: your presence in certain channels is definetely a secret only shared between the ircops and the people in the channel
<kerio>
if you use ssl
<DocScrutinizer05>
tzz
<DocScrutinizer05>
IRC per definition is the opposite of private and secure
<kerio>
it's not about protecting your stuff from the universe
<kerio>
it's about protecting your stuff from the starbucks network operator
<kerio>
or even other users, if there's no encryption on the wifi network
<DocScrutinizer05>
TZZZ!
<kerio>
even making it slightly more annoying to sniff your shit can help
<DocScrutinizer05>
"app XY stores my passwords unencrypted so when somebody hacks my account on this machine, he can easily read out my passwords" BWAHAHAHA
<kerio>
"i don't want to learn about encryption so i'll just pretend it's useless"
<DocScrutinizer05>
"changelog: due to popular demand we introduced ROT13 encryption for passwords in ACME app 4.9"
<kerio>
doesn't really work like that
<bencoh>
:]
<kerio>
but whatever helps you feel better about yourself, i guess
<kerio>
:V
<DocScrutinizer05>
whenever you hope for "improved security" by implementing obfuscation on deeper layers since you doubt the outermost layer is prooperly locked down and secure, you're suffering a *massive* delusion
<bencoh>
we dont doubt the outermost layer, we know it should be considered unsecure
<bencoh>
just like modems ;)
<DocScrutinizer05>
but sure, for public open WiFi a SSL may help a lot
<DocScrutinizer05>
I'd feel somewhat reluctant to authenticate to nickserv over an unsecured connection when I use a public hotspot
<DocScrutinizer05>
so nevermind my frowning on SSL in ZNC, for some usecases it sure makes sense
<DocScrutinizer05>
just saying: last threats we seen that made us change our passwords all were *due to* using (flawed) SSL, not due to _not_ using SSL
<kerio>
was it?
<kerio>
it was a rootkit on one of the servers
<kerio>
how's that related to tls
<DocScrutinizer05>
not sure about it for freenode ircD7
<kerio>
anyway, i like the idea of ECDSA-NIST256P-CHALLENGE for sasl
<kerio>
since it makes the *servers* immune to password sniffing
<kerio>
but based on keypairs instead of your password
<jonwil>
bah, why wont my N900 play its SMS tone properly...
<kerio>
anyway, xchat on n900 can't tls :c
<jonwil>
It can play music via mediaplayer no problems but the same mp3 file as an SMS tone wont play if I send myself a test SMS
<DocScrutinizer05>
:-S
<kerio>
jonwil: something with the cache of tones or smth
<kerio>
try changing it and then changing it back
<jonwil>
Tried that, nothing
<kerio>
also check you're not in silent mode :P
<jonwil>
and no I am not in silent mode
<DocScrutinizer05>
SMS tone (like all "alarm tones") is converted to a .wav format and stored in a special location
<DocScrutinizer05>
some sort of .wav. May also be .au or whatever
<DocScrutinizer05>
andway on picking a ringtone, system tone, whatever, the system "compiles" the audio at config time, so it plays something completely different logically than you think it does
<DocScrutinizer05>
anyway*
<jonwil>
where is that location?

~/.local/cahce or sth

<DocScrutinizer05>
sorry
<jonwil>
hildon-plugins-notify-sv is definatly related, lets pull that apart and see

yep, hildon-sv-notification-daemon is definatly related to ringtone playback
<jonwil>
seems like a reboot fixed it, the smstone plays now

retarting that zoo of daemons isn't exactly trivial

not sure exactly how long my N900 is going to survive anyway, it might be getting the dreaded cellmo failure (seen at least one instance of the "no sim" icon as of late even with inserted SIM card)

Regarding metel sliding mech of n900 i inquired and found that they came from nokia and are not available elsewhere though if lucky at most 30 such pices coud be found if i could track that chain
<DocScrutinizer05>
so the randomness / structure in noise floor after N900 stopped the recharge period might well be from one of the other devices powered by SPSU around
<DocScrutinizer05>
yes, those slider mech are obviously genuine proprietary Nokia parts
<Openbot>

DocScrutinizer51: why in the fuck is xchat compiled with a static and old openssl

<kerio>
stop blaming znc :c

meh! I didn't change anything except updating ZNC

do you have savebuff enabled

<DocScrutinizer05>
(light spreader) I still think - even more now - that printing should be feasible
<DocScrutinizer05>
what I still fail to understand is the elementary difference between printed-on-surface white varnish and glued-to-surface white domesheet adhesive
<DocScrutinizer05>
must be the glue in the end
<DocScrutinizer05>
a friend suggested laser engraving instead of printing
<wpwrak>
(skip_bytes) ah, nice new feature :)
<DocScrutinizer05>
dunno if that works on transparent plastic
<DocScrutinizer05>
we should ask the ligh guide guys how much they call for making a 1000 spreaders
<DocScrutinizer05>
seems they also can make prototypes in 3 working days and "for cheap"
<DocScrutinizer05>
maybe they can make a 1000 prototypes?
<DocScrutinizer05>
maybe cheaper than printing a reel with 50000, given you need the steel rolls for that
<DocScrutinizer05>
well "printing", what they do after prototyping
<DocScrutinizer05>
embossing actually
<DocScrutinizer05>
but who knows, maybe they use a sheet of etched alu in the roll surface, and it's not all that expensive
<wpwrak>
(nik's mail, forwarded) thanks !
<DocScrutinizer05>
oooh that gives me ideas. We are EE we know to etch metal
<DocScrutinizer05>
yw
<DocScrutinizer05>
innovative use for a etched PCB and a flat-iron ;-D
<wpwrak>
ah yes that would produce little bumps :)
<DocScrutinizer05>
I guess I jave to contract whitequark
<DocScrutinizer05>
have to*
<wpwrak>
or machine the "pcb" (whatever material you use) if the bumps need to go deeper
<DocScrutinizer05>
zjey are arounf 0.05
<DocScrutinizer05>
dang!
<DocScrutinizer05>
they are around 0.05
<wpwrak>
1 oz copper is ~35 um
<DocScrutinizer05>
sound about right
<DocScrutinizer05>
exactly what we need
<DocScrutinizer05>
but toner transfer should also work, given we can find white toner
<DocScrutinizer05>
or copperplate print
<DocScrutinizer05>
using white varnish
<DocScrutinizer05>
there's a *lot* to test, and probably all will work to a certain degree (of efficiency)
<DocScrutinizer05>
HMMMM, shooting holes through the whole dang foil of spreader, using electric discharge
<DocScrutinizer05>
or laser
<DocScrutinizer05>
downside: there's no linear relation between "diameter" and flux any more
<DocScrutinizer05>
hey! you coul try a hot needle in your CNC
<wpwrak>
hot pogo pin ? :)
<DocScrutinizer05>
do you have a laser pointer? it's quite some fun to shoot a laser into the lightspreader from side. You could do that even on the spreader on N900, without damaging or removing it
<DocScrutinizer05>
yep, exactly
<DocScrutinizer05>
maybe it heats up by itself at friction to plastic when it spins @ 20k/min
<DocScrutinizer05>
;-)
<DocScrutinizer05>
I'm sure you know in indistry the "weld" plastic together by ultrasonic
<DocScrutinizer05>
the internal friction heats up the plastic and melts it together
<DocScrutinizer05>
seems it's a pretty convenient method
<DocScrutinizer05>
I got nfc about amplitude nor frequency though
<DocScrutinizer05>
I wonder if I just invented the new enegy saving flat-iron, en passant
<DocScrutinizer05>
there's ultrasonic washing machine already, not even needs detergents allegedly
<DocScrutinizer05>
which is why some Unilever bought the patent and never made a product out of it
<vakkov>
DocScrutinizer05: did you re-work the beagles?
<DocScrutinizer05>
I cannot do this, it needs $$$$$ tools to do so
<DocScrutinizer05>
they are at a lab which will rework them
<DocScrutinizer05>
Nikolaus analyzed our options, it's a tad nasty since the lab says they will probably need vapor phase to solder the PoP, and vapor phase is no local measure, it heats up the complete noard. But there are components on the board that don't tolerate such heading up, we will have to remove them prior to soldering the new PoP&SoC, or we accept them going south and turn into a molten blob of plastic
<DocScrutinizer05>
s/noard/board/
<DocScrutinizer05>
some guys in query to me claimed they already did similar rework using IR reflow, which is pretty easily restricted to a local area of the chip only. But - as mentioned before - I cannot do the rework no matter which method, so we need to rely on the guy at lab with the tools and the experience
<DocScrutinizer05>
when he says IR is prone to fail, I'm the last one to argue with this expert
<DocScrutinizer05>
and in the end of the day it's Nikolaus talking to the guy at lab. I don't even know him
<DocScrutinizer05>
I'm the EE who does schematics, not the manufacturing engineer who knows the fab
<DocScrutinizer05>
eventually I'll have to talk to our fab (Global Components) since it's "me" (== Neo900 UG) to contract them in the end
<DocScrutinizer05>
for now Nikolaus is the one in our team who knows all those guys and worked with them on GTA04 already
<DocScrutinizer05>
((EE who does schematics)) every now and then Nikolaus tells me that stuff I designed cannot get built due to restrictions in PCB precision or whatever. He's the expert for turning a schematics into a physical device. I'm the guy who has the longer experience in schematics and designing circuitry
<DocScrutinizer05>
for a very long time he worked in industry actually producing devices, while I always just watched those guys studying what they do and how they do it. I'm the one who designed the devices and when production started I'm usually out
<wpwrak>
you mean, when the production engineers saw what you had designed, an angry mob carrying torches and pitchforks gathered before your office and you had to make a hurried escape ? ;-))

(ir reflow) i kinda wonder if the risk of having to burn a few memory chips wouldn't be better than having the near-certainty of random damage on a global scale ...
