That's a funny name but I'm glad there is something.
<P-G>
It works for text too?
<Pali>
no idea
<Pali>
just now I found that somebody REd that protocol
<P-G>
Hm. Says it's not ready for usage.
<Pali>
anyway, I suggest to abandon that googleshit and use normal xmpp
<P-G>
Yeah but it is convenient for working with non-tech people.
<P-G>
They already have accounts and know how to use it.
<Pali>
I would say I'm tech, but I do not know how to use it...
<Pali>
:D
<P-G>
Lol, neither do I.
<P-G>
And I hate the name Hangouts.
<P-G>
Talk was good.
<P-G>
Hangouts has video, I get it, but it's still a stupid name.
<P-G>
And it's been less reliable since they started adding in all that fancy video stuff.

(3d scans) they're complete in the sense that i scanned everything i found of interest. i didn't scan every bit of the n900, though
<wpwrak>
and the scans are without any post-processing, so for example all vertical walls have a false inclination that corresponds to the shape of the scanning needle
<DocScrutinizer51>
eeew
<wpwrak>
i used a roland mdx-15, which scans by moving a needle over the object. it's an agonizingly slow process but pretty accurate - much better than what "low-cost" optical scanners can do.
<DocScrutinizer51>
maybe provide detailed info about the needle shape?
<DocScrutinizer51>
won't allow for accurate walls but at least users can deduce where to expect errors
<wpwrak>
yeah, i have them *somewhere*. never bothered to try to correct for such things, though. as long as you're just measuring distances, it's easy to correct manually. and it would probably quite a bit of work to write a proper mesh correction for the needle shape. e.g., even at an edge, the needle may be hitting something that isn't that edge. so you need to look at a lot of points.
<wpwrak>
for most measurements you don't need to account for the needle shape - you just measure where the needle found an edge. i explained that in the README of the mesh measuring tool
<wpwrak>
if you really want to 3D-print a case then you need a much more involved process. also, these 2.5D scans will not see all the things you need. e.g., they're completely blind to overhangs.
<DocScrutinizer51>
which is a real problem
<DocScrutinizer51>
and in N900 case we even have tunnels
<wpwrak>
yes. the scans give you a basis for developing models, but they're not meant to just "copy" a case with a 3D printer
<wpwrak>
if that's your goal, give me some 100 kEUR and a bit of time ;-)
<DocScrutinizer51>
simple ones like for switches, and nasty ones like the sound chambers
<ds2>
are there that many irregular surfaces that one NEEDS to scan it?
<wpwrak>
ds2: it's full of small details that are a pain to measure manually
<ds2>
wpwrak: Was thinking more of a CMM
<ds2>
rather then a dumb "scan", use the CMM to measure points and transcribe to a cad drawing
<wpwrak>
CMM = ?
<DocScrutinizer51>
~wtf cmm
<infobot>
Gee... I don't know what cmm means...
<ds2>
Coordinate measuring machine... that needle scannner of yours with better controls
<wpwrak>
DocScrutinizer51: my usual process is to first look at photos, scans, and maybe the device to understand the shape of something. sometimes it's trivial, sometimes there are surprises
<ds2>
so rather then automated probing it and trying to follow contours, teh operator can move the probe to specific places. and if needed flip the unit around. doesn't quite do tunnels but short of X-Rays, nothing much will
<P-G>
X-rays, huh?
<P-G>
Now there's an idea.
<ds2>
tunnels
<ds2>
how else canyou see inside w/high rez?
<DocScrutinizer51>
hehe
<wpwrak>
DocScrutinizer51: then i do measurements on the scans to make a correct model. where "model" doesn't mean a 3D CAD model but some 2D drawings, the objective usually not being to recreate the object i'm examining but to find out what fits inside
<wpwrak>
ds2: yes, that would be a possibility if we had such a device with sufficient accuracy. they're not cheap, though. probably as much as my CNC mill with scanner, if not more expensive. and they don't let you share the process easily while anyone can measure things in the 2.5D scans
<DocScrutinizer51>
which is exactly what the scans are for
<wpwrak>
yup. they work great for the purpose for which i made them. but if you want to do something else, then they may be less helpful. they may still be the best bet you have, though ;-)
<DocScrutinizer51>
sure
<ds2>
wpwrak: much more then a proper CNC mill w/scanner
<ds2>
but that would be THE machine for the job
<wpwrak>
(work great) perhaps except that i should have added a "record mesurement operation" mode to the measurement tool. that way, one could review measurements i made, check that i looked at the right place, etc. didn't think of that in time. maybe, some day, when i feel very bored ;-)
<ds2>
mills have ways designed to withstand forces and are compromised to resist them. a CMM doesn't. it just tries to maximize accuracy
<ds2>
the local JC had one donated to them
<wpwrak>
ds2: my mill scans at a resolution of 50 um in X/Y and 25 um in Z, so that's already quite decent for an unattended process. and for placing component and such, we need maybe 100 um, worst-case, so there's some margin for error.
<wpwrak>
donations of fancy equipment are of course always welcome ;-)
<wpwrak>
i'd prefer a nice sterolithographic printer, though :)
<DocScrutinizer51>
watch out what you ask for ;)
<wpwrak>
ah, one condition: handover point in downtown Buenos Aires, so that i don't have to mess with customs :)
<DocScrutinizer51>
not only customs, also transport
<wpwrak>
argh. gotta finish shopping ... they close in 15'
<ds2>
recipient pays for riggers and insurance ;)
<ds2>
the one they donated has a dinner table size slab of granite 2' thick and a gantry of of similar thickness of granite
<ds2>
arrrggggg. n900 croaking :(
<ds2>
TS going nuts
<wpwrak>
ds2: okay, that may be tricky to move to my apartment. if it fit in the elevator, no problem, though.
<ds2>
wprak: you mean assuming elevator doesn't plunge down the shaft uncontrollably
<wpwrak>
DocScrutinizer51: (transport) have car, don't mind travelling :)
<ds2>
i wonder how painful it is to swap motherboards between 2 N900's
<wpwrak>
less painful than having someone drop that granite table on your foot ;)
<ds2>
one N900 w/MB that can't talk to the SIM and one N900 with a TS that is going crazy... arrggg
<ds2>
now if the neo900 was available today....
<P-G>
We could all just go to the store and pick one up. :D

ds2: "light swap" (nokia speak) is as simple as it gets
<DocScrutinizer05>
only thing simpler than that: swap display half
<ds2>
does it really require a new set of screws? their docs says to replace them
<DocScrutinizer05>
swap display is (for one device): unscrew 4 philips0, carefully unplug a B2B connector using e.g. a credit card as lever. plug in new B2B carefully while not damaging/bending the plug assembly or the flex cable, put the new display half into place and slightly tighten the 4 philips0
<DocScrutinizer05>
(new screws) I never did that
<ds2>
'k thanks for the comments...guess I got a new project this weekend
<DocScrutinizer05>
you do that when you can afford it
<ds2>
more of being able to source them
<DocScrutinizer05>
the whole procedure takes 30 min amd a beer, to be on the safe side and not damage anything by rushing it
<ds2>
ts is sending out fake taps so device never goes to sleep and battery life goes to hell :(
<DocScrutinizer05>
either your touchpanel or your flex cable got damaged
<ds2>
I think the touchpanel is worn
<ds2>
it is an old unit
<DocScrutinizer05>
when you got a spare display half, you're good for now. Long term you may want to swap whatever went south
<ds2>
can I still get digitizers for the N900?
<ds2>
or better yet - are you guys able to source that part?
<DocScrutinizer05>
bith the flex cable and the touchpanel are available for 10..20 bucks and are "easy" to replace
<DocScrutinizer05>
both*
<ds2>
that sounds like a good investment
<DocScrutinizer05>
yes, we will want to source a 50some digitizers
<DocScrutinizer05>
the N900 I managed to access are not exactly unused, so we might need a few spares for bad digitizers
<DocScrutinizer05>
if I had some spare funds, I already had sourced a 100 or 200 flex cables as well, since you can get them for ~7 bucks
<ds2>
ebay?
<DocScrutinizer05>
err yes, first approach ebay. Though I guess I finally found them on aliexpress or sth
<ds2>
'k
<DocScrutinizer05>
so: google
<ds2>
*nod*
<DocScrutinizer05>
for flex beware of fakes with camera dummy!
<ds2>
it almost sounds like digitizer going south is a very common issue
<DocScrutinizer05>
yes, possible
<DocScrutinizer05>
I think the separator oil gets sticky
<ds2>
it is oil? thought it was just a spacer + air
freemangordon has quit [Ping timeout: 245 seconds]
<DocScrutinizer05>
nah, this is oil, way more sensitive
<DocScrutinizer05>
at least afaik, never killed one to check for myself, only read reports of guys killing theirs and having a sticky film on digitizer
<wpwrak>
i guess it's time for a remake of "godzilla" ...

ugh, that polarcel battery is worn. BME yells "battery almost empty" while the bq27200 chip 3 cycles after correctly completed learning cycle still shows 50% capacity

that's why you use the bme replacement
<DocScrutinizer05>
nah, the bme replacement prolly had tried to discharge battery to 6% and system gone south due to brownout way before that
* DocScrutinizer05
does a few tweaks to system, so "bq27200.sh 60 >>/var/log/battlog" gets autostarted on every boot
<DocScrutinizer05>
maybe I rather should use ~user/MyDocs/battlog.log

hmm no, that's also inconvenient

ohmy, I guess I will need a real 4-liner shelscript for that ;-)
