15:56.03wpwrakceene: another block-diagram-with-locations update: https://neo900.org/stuff/werner/v2loc/v2loc
15:57.07wpwraki changed the background colors to be generally lighter, so that black text is still readable. before, i set some text to white but that didn't really work.
15:58.11ahyckawpwrak http://imgur.com/mwgEms5
15:58.13wpwrakalas, it now has a fairly greyish look (not too unlike what i see when peeking out of the window :), but i hope readability has improved
15:58.22ahyckathis a very first approach, just to see what fits
15:58.38ahyckaonly the biggest components have been placed without any consideration whatsoever to their real location
15:59.00ahyckathere are some other small chips that can fit in the empty space
15:59.28wpwrakhmm, that scale looks strange
15:59.29ahyckaand lots of smd components, most of which will probably decoupling capacitors which are not also easier to place on the opposite side of the board, but also very recommended
15:59.37ahyckathat's as imported from eagle
15:59.49ahyckaalmost or maybe all footprints have been imported without problem
15:59.55wpwraklemme check ...
15:59.57ahyckathe biggest thing is the modem
16:00.00DocScrutinizer05it seems you've put a rather large second SIM-tray in there
16:00.08wpwrakaah, that's the modem. okay
16:00.15ahyckayep, biggest thing is the modem
16:00.18ahyckatwo simtrays
16:00.32ahyckaleftmost is wlan
16:00.34ahyckavibrator below
16:00.38ahyckaspeakers at each corner
16:00.45ahyckasmall bob connector up right
16:01.06ahyckaIR above modem, near the edge of the pcb
16:01.18ahyckaand something to the right of one speaker that i just forgot what it is
16:01.55ahyckaah, that's the nfc controller
16:02.04ahyckaeverything else is either small chips or smd components
16:02.22ahyckait seems that these things will fit very easily
16:03.06DocScrutinizer05U1601 is TRF7970
16:03.16DocScrutinizer05NFC
16:03.37ahyckayep, correct
16:03.52ahyckaas i say, i've just placed biggest things to see if they fit together
16:04.00ahyckaas a vast approach, looks good
16:04.02DocScrutinizer05:nod:
16:04.09DocScrutinizer05thanks a lot
16:04.26ahyckathe numbers you'ev passed to ceene are quite good too
16:04.39ahyckaas 100x50 which is a rectangle inside the pcb
16:04.42ahyckais 5000mm^2
16:04.46ahyckaof which we have two sides
16:04.56ahyckaso that's cleary more than 6000mm^2
16:05.01ahyckaas 10>6 :)
16:05.07DocScrutinizer05wpwrak: could you please have a closer look and suggest further action, I need to go shopping for 2h
16:09.58wpwraki think the next items would be to define exact component locations for the bits that need to be at a specific place, and to integrate the pending changes into the schematics
16:10.00DocScrutinizer05btw we won't use that IrDA module
16:10.28ahyckayeah, i guess simcard and other things have strict placement definitions
16:10.34wpwraklater on we'll also need a height profile for S4 (to match the slider) but that's not really a concern for v2
16:10.47ahyckaif that irda module is not the tone, schematic shall be updated before routing then
16:11.03ahyckas/tone/one/
16:11.21ahyckablames infobot
16:13.41wpwraksim#2 is also quite different. and i still have to find a nice place for it :) well, the exact place. we have a rough location (front edge, to the right, on S2)
16:14.30ahyckaok
16:14.34ahyckawe're going home now!
16:14.35ahyckacya!
16:14.54wpwrakahycka: seeya ! and thanks a lot !
16:18.01DocScrutinizer05[2016-05-29 Sun 18:30:09] <DocScrutinizer05> sheet#19 please discard U1902 "alternative IrDA module"
16:18.20DocScrutinizer05[2016-05-29 Sun 18:24:19] <DocScrutinizer05> soory for above mistake: leading *LOWER* and trailing *UPPER* in schematics
16:18.21DocScrutinizer05[2016-05-29 Sun 18:25:41] <DocScrutinizer05> except sensors (sheet#10) which all may go to upper
16:18.23DocScrutinizer05[2016-05-29 Sun 18:28:28] <DocScrutinizer05> for sheet#18 (hackerbus) please see the note and refer to the HB.pdf from resources which has details on the connectors to be used

18:53.28DocScrutinizer05just the bot had a hickup on the "apt" nick/account, which I learned why and how to work around that
