2013-11-14 01:47 <DocScrutinizer05> may I guess? the driver is written so it works on different platforms and it finds out about fifo size of current platform by reading a register of musb-core IP block. Now when that register isn't existing on jz4740 then you probably need to get that info from elsewhere, worst case you need to hardcode it, according to what the datasheet/TRM says is the fifo size the musb-core is using per default
2013-11-14 01:47 <DocScrutinizer05> mere guessing, a shot into the dark
2013-11-14 01:50 <wpwrak> that's what it sounds like. but a bit of A/B testing should reveal such things. maybe not immediately, but apelete has been at this for weeks, so i'd imagine that pretty much every line of code has been surrounded by debugging printks by now ...

2013-11-14 09:42 <apelete> larsc: does ram_bits should be specified in glue driver or platform data ?
2013-11-14 09:43 <apelete> was thinking about reading the ram_bits register (raminfo actually) from within glue driver and store it in the musb driver structure
2013-11-14 09:46 wej has quit [Ping timeout: 260 seconds]
2013-11-14 09:51 <larsc> is there a ram_bits register on the jz4740 core?
2013-11-14 09:58 <apelete> larsc: yes, there is a ram_bits field in the raminfo register
2013-11-14 09:59 <wpwrak> whitequark: bah, lame. direct thermal plasma printing would be so much more fun.
2013-11-14 10:05 <larsc> apelete: ah ok good
2013-11-14 10:07 <larsc> oh, there is even one that tells you about the number of eps
2013-11-14 10:09 <apelete> yeah, that's epinfo I guess. need to find out how to use these to setup endpoints with ep_config_fom_table()
2013-11-14 10:11 <apelete> the jz4740_udc driver hardcodes 4 endpoints, and that's what I specified in platform data but it does not help much at this point
2013-11-14 10:12 <larsc> it looks a bit as if the config is static
2013-11-14 10:13 <larsc> or the fifo config registers are just not documented
2013-11-14 10:14 <larsc> "/* NOTE:  for RTL versions >= 1.400 EPINFO and RAMINFO would be better than static musb->config->num_eps and DYN_FIFO_SIZE */"

2013-11-14 11:19 <DocScrutinizer05> hello hw hackers! :-) I have a design problem I'd ask you to suggest solutions for. I hope you might help me out
2013-11-14 11:23 <DocScrutinizer05> on Neo900 we can't find 1GByte PoP-168pin LPDDR(1) chip to place on top of the DM3730 CPU. Either you know of any chip that would offer 1GB and is supposed work with DM3730 or alternatives like using DDR2 outside the specs, or a piggyback mini-PCB to solder 2 PoP chips a 512MB on top of the CPU. Or I'd need a suggestion how to attach *fast* storage to the system, to serve as swap (hint: flash is usually NOT fast, particularly on
2013-11-14 11:23 <DocScrutinizer05> writes).
2013-11-14 11:26 <wpwrak> using PoP means you just made sourcing about ten times harder. i guess the first question would be if you could put the RAM somewhere on the side or below the CPU
2013-11-14 11:27 <DocScrutinizer05> annoying detail: Nokia N9 *has* a 1GB PoP, but that's unobtainium and not from this world
2013-11-14 11:27 <wpwrak> if you need to move something else away to make room, maybe that could go on some daughterboard
2013-11-14 11:28 <DocScrutinizer05> wpwrak: alas that formfactor isn't available for OMAP3 SoCs
2013-11-14 11:28 <wpwrak> (unobtainium) yes, of course. we learned that sort of lessons at openmoko ;-) (not that we actually failed to get chips in the end. it was just a LOT harder than one may imagine)
2013-11-14 11:28 <DocScrutinizer05> http://processors.wiki.ti.com/index.php/Memory_Vendor_Selection_Guide#DRAM_Selection
2013-11-14 11:29 <DocScrutinizer05> the chip in N9 is not known by aunt google - of course also no chip manuf has any such critter (officially)
2013-11-14 11:30 <wpwrak> (form factor) i don't know what you mean. are you saying the OMAP3 has the RAM bus only on PoP ?
2013-11-14 11:30 <DocScrutinizer05> I searched for days for sparepart RAM for N9 but N9 repair service doesn't offer anything like that
2013-11-14 11:30 <DocScrutinizer05> yes
2013-11-14 11:31 <wpwrak> bummer
2013-11-14 11:31 <DocScrutinizer05> http://processors.wiki.ti.com/index.php/Memory_Vendor_Selection_Guide#Sitara_Memory.C2.A0Package_options
2013-11-14 11:31 <wpwrak> maybe find a list where disgruntled ex-nokia or soon-to-be-ex-nokia hw folks hang out. and ask there ?
2013-11-14 11:32 <DocScrutinizer05> AM/DM37x - PoP and Discrete :: DRAM - PoP only. SDRC signals occur only on top balls
2013-11-14 11:32 <wpwrak> so yours is a CBC, not CBB
2013-11-14 11:32 <DocScrutinizer05> already did
2013-11-14 11:33 <wpwrak> could you source a CBB or CUS instead ?
2013-11-14 11:33 <DocScrutinizer05> wpwrak: we got 37xx
2013-11-14 11:33 <wpwrak> ok, CBO or CUS :)
2013-11-14 11:33 <wpwrak> s/CBO/CBP/
2013-11-14 11:33 <qi-bot> wpwrak meant: "ok, CBP or CUS :)"
2013-11-14 11:34 <DocScrutinizer05> ooh, CUS
2013-11-14 11:34 <wpwrak> yes, CUS. according to the table, CBP still would need PoP
2013-11-14 11:34 <DocScrutinizer05> yeah, I have to check if CUS is available, I simply didn't see (literally) this line
2013-11-14 11:35 <DocScrutinizer05> thanks a megaton
2013-11-14 11:35 <wpwrak> actually, i wonder if people would really buy PoP without memory. didn't the chinese number stations turn up anything ?
2013-11-14 11:35 <DocScrutinizer05> sometimes it just needs a second pair of eyes to look at some pretty clear info ;-D
2013-11-14 11:35 <wpwrak> hehe :)
2013-11-14 11:35 <DocScrutinizer05> PoP been an agony since 2 months now
2013-11-14 11:36 <DocScrutinizer05> literally nobody seems to have bothered to build 1GB 168p PoP
2013-11-14 11:36 <wpwrak> yeah, i've witnessed plenty of PoP hell at OM :)
2013-11-14 11:36 <DocScrutinizer05> except that mythical N9 chip
2013-11-14 11:36 <wpwrak> ah, that's where the swap idea comes from
2013-11-14 11:36 <DocScrutinizer05> yes
2013-11-14 11:38 <wpwrak> actually, if you have slow writes, that may still work: most applications are bursty, so you may be able to get away by simply keeping - on average - a large enough pool of spare pages
2013-11-14 11:38 <wpwrak> but then, swapping to flash sounds evil
2013-11-14 11:39 <DocScrutinizer05> grrr, now again back to CUS formfactor specs, digging up all the annoyinaces this comes with. I guess Nikolaus will kill me for asking him to route RAM as well on that gordian knot of traces under the SoC
2013-11-14 11:40 <DocScrutinizer05> (swap) Maemo already has swappiness=100
2013-11-14 11:40 <DocScrutinizer05> this doesn't help in the end
2013-11-14 11:40 <DocScrutinizer05> (evil) yes, that too
2013-11-14 11:42 <wpwrak> (swap) ah, pity. get people to write better code ;-) i still remember the days when 16 kB meant that you'd never have to worry about running out of memory ever again.
2013-11-14 11:43 <wpwrak> so, instead of Flash, maybe add a ROM BASIC ;-)
2013-11-14 11:45 <larsc> or SliverLight
2013-11-14 14:04 <mth> DocScrutinizer05: recent Linux kernels can swap to compressed memory (ZSWAP)
2013-11-14 14:05 <DocScrutinizer05> yes, I know
2013-11-14 14:05 <DocScrutinizer05> afaik it's already implemented in fremantle, at least with powerkernel
2013-11-14 14:06 <mth> it helped us on Dingoo A320 (32MB)
2013-11-14 14:06 <mth> but probably not a substitute for having enough RAM chips
2013-11-14 14:06 <DocScrutinizer05> yep
2013-11-14 14:07 wej has joined #qi-hardware
2013-11-14 14:07 <DocScrutinizer05> Nikolaus said we basically can use CUS, but it has some interfaces missing compared to CBP
2013-11-14 14:07 <DocScrutinizer05> :-(
2013-11-14 14:08 <DocScrutinizer05> we have to check if we can get away with one UART, one McBSP and a few GPIOs missing
2013-11-14 14:08 <DocScrutinizer05> sounds nasty
2013-11-14 14:10 <DocScrutinizer05> the alternative (720MHz  OMAP3530CBB) sounds like a regression even worse than 1GHz DM3730 with only 512MB RAM
2013-11-14 14:11 <wpwrak> just a few things missing doesn't sound too bad. making do with few resources than you need is part of the game ;-)
2013-11-14 14:11 <DocScrutinizer05> we'd lose all selling points of Neo900 basically
2013-11-14 14:13 <DocScrutinizer05> well, we planned for the UART3 (formerly "unused" on N900: console on testpoints) to become proper IrDA/CIR/console_over_SIR
2013-11-14 14:13 <wpwrak> and if you really just gpio-starved, you can always toss in a little helper mcu as io expander
2013-11-14 14:13 <DocScrutinizer05> GPIO are not my concern
2013-11-14 14:13 <DocScrutinizer05> McBSP and - to a lesser extent - UART are
2013-11-14 14:13 <wpwrak> everything else can be reduced to gpio ;-)
2013-11-14 14:14 <DocScrutinizer05> haha :-D
2013-11-14 14:14 <DocScrutinizer05> DAMN friggin PoP!
2013-11-14 14:15 <DocScrutinizer05> I seriously ponder if a piggyback PCB would be feasible
2013-11-14 14:15 <wpwrak> regarding PoP, heed the wise advice of nancy reagan, "just say no" :)
2013-11-14 14:15 <wpwrak> if you want an unending yield nightmare, then you're on the right track :)
2013-11-14 14:23 <wpwrak> in the old days, it used to be the japanese who were the world leaders in batshit crazy but admittedly very creative abuses of technology. now it seems that china is catching up there, too: http://www.youtube.com/watch?v=d3CWLCoQu7c
2013-11-14 14:26 <DocScrutinizer05> no, *I* am the king in this discipline ;-P
2013-11-14 14:27 <wpwrak> now we know what you need those extra interfaces for :)
2013-11-14 14:27 <wpwrak> hey, you just crossed 150. almost there !
2013-11-14 14:28 <DocScrutinizer05> well, I probably should've watched the video *before* answering ;-P
2013-11-14 14:28 <DocScrutinizer05> actually?
2013-11-14 14:28 <DocScrutinizer05> WOW
2013-11-14 14:29 <DocScrutinizer05> DUH 500
2013-11-14 14:34 <DocScrutinizer05> btw same old horseshit about patents on WCDMA calls, with royalties and whatnot. Luckily Nikolaus knows the Cinterion guys \o/
2013-11-14 14:37 <DocScrutinizer05> now this whole "M2M" adverising on http://m2m.gemalto.com/products/m2m-advanced makes a lot more sense
2013-11-14 14:38 <DocScrutinizer05> GOD! Please kill all patent trolls with fire from heaven
2013-11-14 14:39 <DocScrutinizer05> or like we use to say here "soll sie alle der blitz beim scheissen erschlagen!" ;-)
2013-11-14 14:43 <wpwrak> i'd opt for them getting arthritis and st vitus' dance at the same time
2013-11-14 14:48 <DocScrutinizer05> only if it's severe enough to stop them from pursuing their patent trolling
2013-11-14 14:48 <DocScrutinizer05> but then it's even better, yeah
2013-11-14 14:49 <DocScrutinizer05> and a long life to them then
2013-11-14 14:51 <wpwrak> that's the spirit (-:C
2013-11-14 14:51 <larsc> live forever but continue ageing as normal
2013-11-14 14:57 <wpwrak> after about 120 years, putrefaction inevitably sets in. so there'd be a zombie stage. after that, "life" would continue as a moving skeleton. with the right choice of clothing, nobody would have to notice
2013-11-14 14:58 <DocScrutinizer05> btw, about patents: http://www.google.com/patents/US6926418  bites our ass with getting a replacement for domesheet unobtainium
2013-11-14 14:58 <DocScrutinizer05> now going for soldering the domes to the PCB and placing a lightgiude plastic foil above it
2013-11-14 14:59 <DocScrutinizer05> guide*
2013-11-14 14:59 <wpwrak> are domes really soldered ? i thought they were generally glued
2013-11-14 14:59 <DocScrutinizer05> dunno, Nikolaus found some that aiui are soldered
2013-11-14 15:00 <wpwrak> i'd double-check that ;) the ones i found look at first sight as if they were for soldering ... but they aren't
2013-11-14 15:01 <DocScrutinizer05> makes sense when the "solderposts" move while pressing the switch
2013-11-14 15:02 <wpwrak> digi-key has some in a, as far as i remember, 5x7 mm grid. need fancy vias or solder mask, though. so not so easy for everything-DIY-ers like myself
2013-11-14 15:04 <wpwrak> ah, nonsense. it's 10.5 x 9 mm
2013-11-14 15:04 <wpwrak> this sort of critter: http://www.digikey.com/product-detail/en/B3DA-0010-A/SW1019-ND/1522995

2013-11-14 15:22 <DocScrutinizer05> lemme find the mail where Nikolaus told me about the Panasonic domes he found
2013-11-14 15:48 <DocScrutinizer05> can't spot it, but they are Panasonic and in a plastic frame where the dome can "move"
2013-11-14 15:50 <DocScrutinizer05> other problem: B2B connector similar to Hirose DF30FB-60DS-0.4V but with 64 pins. Anybody able to share any helpful info bit or pointer?

2013-11-14 16:35 <viric> ah maybe I posted it bad?

2013-11-14 16:35 <viric> fixed!
2013-11-14 16:36 <viric> now you should update the sources url in aur
2013-11-14 16:40 <DocScrutinizer05> wpwrak: thanks! but it has to match http://www.ebay.com/bhp/nokia-n900-flex
2013-11-14 16:41 <wpwrak> and how do you tell that it doesn't ? :)
2013-11-14 16:41 <DocScrutinizer05> I already tried to unsolder one of the 64p headers on the flex cable, but it's glued, so rework for 200 devices is most likely a PITA
2013-11-14 16:41 <kyak> viric: thanks, and i fixed the pkgbuild
2013-11-14 16:42 <DocScrutinizer05> wpwrak: I have ~5 B2B here to inspect them closely, and I think they look different than those panasonic
2013-11-14 16:42 <viric> thank you! I created all the misunderstanding :)
2013-11-14 16:42 <DocScrutinizer05> wpwrak: I dunno if the plug is a standard and only the build details differ to make them look like they are not matching
2013-11-14 16:43 <kyak> viric: i think you ping timeouted couple of days ago and missed my message (i don't display joins/parts/quits)
2013-11-14 16:43 <DocScrutinizer05> but since none of the manufs seems to specify any standard the connectors adhere to, I suspect it's "proprietary"
2013-11-14 16:43 <viric> ahh
2013-11-14 16:43 <viric> maybe
2013-11-14 16:43 <viric> I can't know
2013-11-14 16:43 <kyak> viric: and so i implemented temporary fix, which proved to be wrong :)
2013-11-14 16:44 <viric> what was wrong?
2013-11-14 16:44 <wpwrak> DocScrutinizer05: yeah, i think you need get a few that look similar enough and then just try if anything fits
2013-11-14 16:44 <DocScrutinizer05> :nod: :-S
2013-11-14 16:44 <wpwrak> do you know the original part number ?

2013-11-14 16:45 <DocScrutinizer05> Nokia is notorious to not publish ANY real part numbers of *anything*
2013-11-14 16:46 <viric> :) well seen

2013-11-14 16:47 <kyak> viric: if possible, you should get rid of the second version number in download url.. Also, you web server for some reason sends filegive-0.7.1.tar.gz?uuid=v0.7 file name, which is just not nice
2013-11-14 16:47 <DocScrutinizer05> wpwrak: however I wonder where from all those "second source" flex builders got theirs from - ok it's the M-part and we need the F-part for mainboard, but...
2013-11-14 16:47 <viric> kyak: although I got a column in a german magazine!
2013-11-14 16:47 <kyak> v0.7.1 now, i mean :)
2013-11-14 16:47 <viric> kyak: in the paper version of http://www.heise.de/ct/
2013-11-14 16:47 <DocScrutinizer05> there must exist some secret knowledge inside China
2013-11-14 16:48 <kyak> viric: oh, it's interesting! what do you write about?
2013-11-14 16:48 <viric> kyak: no. Someone wrote about filegive, simply. Not me :)
2013-11-14 16:48 <kyak> ah, ok :)
2013-11-14 16:48 <DocScrutinizer05> viric: OOOOH!
2013-11-14 16:49 <kyak> viric: with recent news and such, filegive is an interesting thing..
2013-11-14 16:49 <viric> It's the bee's knees!
2013-11-14 16:50 <viric> I plan to add ngrok support, which should help poor people behind cgNAT
2013-11-14 16:50 <viric> (more integrated that what you can do manually though)
2013-11-14 16:50 <viric> DocScrutinizer05: ? do you know that magazine? I don't.
2013-11-14 16:50 <DocScrutinizer05> sure! :-D
2013-11-14 16:50 <DocScrutinizer05> it's THE european computer mag
2013-11-14 16:50 <kyak> Das Kommandozeilen-Tool Filegive veröffentlicht Dateien im Internet oder nimmt sie entgegen. Es erspart Umwege über Dienste wie Dropbox.
2013-11-14 16:51 <viric> ah :D
2013-11-14 16:51 <DocScrutinizer05> on same level like US Byte mag
2013-11-14 16:51 <DocScrutinizer05> Byte is a tad older
2013-11-14 16:51 <viric> I also don't know that
2013-11-14 16:52 <kyak> viric: have you already noticed increased downloads?
2013-11-14 16:52 <viric> hm I didn't check
2013-11-14 16:53 <kyak> be prepared :)
2013-11-14 16:54 <viric> 214 downloads of the windows prebuilt
2013-11-14 16:54 <DocScrutinizer05> c't is sold in every gas station and every supermarket now
2013-11-14 16:54 <viric> vs zero of the previous month :)
2013-11-14 16:54 <DocScrutinizer05> I guess 10% of german population read it
2013-11-14 16:55 <viric> auhm
2013-11-14 16:55 <kyak> cool, so it increased infinite times :)
2013-11-14 16:55 <viric> :)
2013-11-14 16:56 <viric> but filegive uses nist curves. Not for the überparanoid
2013-11-14 16:57 <wpwrak> viric: better offer alternatives
2013-11-14 16:57 <viric> I should, rsa at least. next version.
2013-11-14 16:58 <wpwrak> and make sure it doesn't do things like switching to RC4, or silently dropping encryption altogether
2013-11-14 16:59 <kyak> first thing is to make sure your users downloaded what you actually uploaded (i mean the tarball)
2013-11-14 16:59 <kyak> maybe for some users this binary will be substituted by another one
2013-11-14 16:59 <kyak> (überparanoid)
2013-11-14 17:01 <wpwrak> DocScrutinizer05: you should measure the real connector (especially the plug side) with a caliper. then you'd have at least correct reference dimensions.
2013-11-14 17:06 <DocScrutinizer05> wpwrak: I think at least the http://www.electronicproducts.com/Nokia_N900_Mobile_Phone-whatsinside_text-90.aspx guys did
2013-11-14 17:06 <DocScrutinizer05> I'll redo it nevertheless
2013-11-14 17:09 <DocScrutinizer05> Pin  Count 64; IO  Pitch 0.40;  Length  (mm)  15.70;  Width  (mm) 5.00;  Height  (mm) 0.80

2013-11-14 17:11 <wpwrak> that doesn't tell you the width of the actual plug
2013-11-14 17:15 <wpwrak> ah, and it's the plug you need, not the receptacle
2013-11-14 17:17 rz2k has joined #qi-hardware
2013-11-14 17:18 <DocScrutinizer05> the plug is 14.50mm
2013-11-14 17:18 <DocScrutinizer05> on my caliper
2013-11-14 17:18 <DocScrutinizer05> total outer dimension
2013-11-14 17:20 <DocScrutinizer05> we need the receptacle as shown on the scans I linked 4 above
2013-11-14 17:20 <DocScrutinizer05> the plug I just netered is on the flax cable and is fixed and given
2013-11-14 17:20 <DocScrutinizer05> metered*
2013-11-14 17:22 <wpwrak> you need the exact dimensions of the "oval" part that goes into the receptacle
2013-11-14 17:22 <wpwrak> i.e., "penis diameter", not "width of the hips"
2013-11-14 17:24 <DocScrutinizer05> 14.50mm
2013-11-14 17:24 <wpwrak> 14.50 mm x ?
2013-11-14 17:25 <DocScrutinizer05> which makes for 1,2mm for the "hips" on both sides of the F-part
2013-11-14 17:25 <DocScrutinizer05> which looks about right
2013-11-14 17:26 <wpwrak> you mean 2 * 0.6 mm "hips" (or walls) for the length
2013-11-14 17:27 <wpwrak> but you still don't have the width. the length is more or less give by the pitch, for the width there seem to be a lot of choices
2013-11-14 17:27 <DocScrutinizer05> yes
2013-11-14 17:27 <DocScrutinizer05> x 2.92mm (depending on how hard I squeeze the contact springs with caliper)
2013-11-14 17:29 <DocScrutinizer05> s/(depending on how hard I squeeze the contact springs with caliper)/(the springs are inside yet another "F" part of this "M" part)/
2013-11-14 17:29 <qi-bot> DocScrutinizer05 meant: "x 2.92mm ((the springs are inside yet another "F" part of this "M" part))"
2013-11-14 17:30 <DocScrutinizer05> so actually you could call the mainboard larger one the M part and the flex side one the M part
2013-11-14 17:30 <DocScrutinizer05> so actually you could call the mainboard larger one the M part and the flex side one the F part
2013-11-14 17:31 <wpwrak> oh, i see. then you should measure the cable side
2013-11-14 17:31 <DocScrutinizer05> basically the mainboard one works like a cinch plug
2013-11-14 17:32 <DocScrutinizer05> and the flec side like a cinch receptacle
2013-11-14 17:32 <DocScrutinizer05> flex*
2013-11-14 17:33 <DocScrutinizer05> on http://maemo.cloud-7.de/Gallery-N900-exploded/n900_01.jpeg the actual contacts are the tiny golden things next to the center
2013-11-14 17:35 <wpwrak> ah yes, of course.
2013-11-14 17:35 <DocScrutinizer05> the distance of those golden contacts is ~1.60mm (hard to probe)
2013-11-14 17:37 <DocScrutinizer05> also there actually the springs would move in when I apply force
2013-11-14 17:38 <DocScrutinizer05> (and out when I probed the 1.60mm on flex)
2013-11-14 17:39 <wpwrak> 1.6 mm sounds about right. measuring in your high-res image, i got 1.56 mm (with a bit of guesswork, so 1.6 mm is well within error tolerances)
2013-11-14 17:40 <DocScrutinizer05> yes, absolutely
2013-11-14 17:40 <DocScrutinizer05> my 1.60 thend to err to the larger numbers
2013-11-14 17:40 <DocScrutinizer05> tend*

2013-11-14 17:52 <wpwrak> hmm, nothing that looks similar on digi-key
2013-11-14 17:53 <wpwrak> you may have to go through the catalogs of hirose, molex, jae, panasonic, etc.
2013-11-14 17:55 <DocScrutinizer05> yeah
2013-11-14 17:55 <DocScrutinizer05> if only there were proper catalogs
2013-11-14 18:02 <DocScrutinizer05> I guess somewhere on this planet there must be a special shop that's only selling connectors and knows every damn connector existing. Only I not yet found that shop :-/
2013-11-14 18:02 <DocScrutinizer05> component sourcing, a never ending nightmare
2013-11-14 18:05 <wpwrak> or maybe there are tens of thousands of shops, each having bags full of connectors, and when you go there and bring your device, they will try until they find one that fits :)
2013-11-14 18:06 <DocScrutinizer05> no such shop in my town. wouldn't know any in Germany at large either
2013-11-14 18:07 <DocScrutinizer05> I probably should check out aliexpress.com if they got some wishlist function
2013-11-14 18:09 <DocScrutinizer05> this silly connector kills our project :-/
2013-11-14 18:19 <wpwrak> maybe make a drawing that clearly shows what it has to be like, then ask around

2013-11-14 19:04 <DocScrutinizer05> http://www.molex.com/pdm_docs/sd/5024266410_sd.pdf  almost, just 2.6 instead of 5mm wide
2013-11-14 19:20 <wpwrak> why do you care about the width ? that's just the frame
2013-11-14 19:21 <wpwrak> since you have your own layout anyway, you adapt to whatever the connector needs
2013-11-14 19:23 <viric> wpwrak: it shouldn't go to rc4
2013-11-14 19:53 <DocScrutinizer05> wpwrak: I don't care about the width really, but it has to match the other dimensions, and that's not given
2013-11-14 19:56 <DocScrutinizer05> http://www.digikey.com/product-detail/en/WP3-P064VA1-R500/670-2642-2-ND/3725821  almost matches regarding the build, also just not wide enough
2013-11-14 20:03 <DocScrutinizer05> http://www.molex.com/pdm_docs/sd/5000275091_sd.pdf  has 3.04, which seems absolutely correct
2013-11-14 20:03 <DocScrutinizer05> design is also correct, on this side view
2013-11-14 20:04 <DocScrutinizer05> 14.5 (A) length, correct
2013-11-14 20:06 <DocScrutinizer05> http://www.molex.com/pdm_docs/sd/5000241691_sd.pdf  length 15.7mm correct
2013-11-14 20:06 <DocScrutinizer05> I think this is BINGO :-)
2013-11-14 20:13 <dos1> \o/
2013-11-14 20:22 <DocScrutinizer05> only 6 hours of contiguous searching and already the right one ;-P
2013-11-14 20:22 <DocScrutinizer05> at least I really really hope so, and it seems to match exactly

2013-11-14 20:54 <DocScrutinizer05> 0.13..0.55$   good enough
2013-11-14 20:55 <wpwrak> ah yes, MOQ 100. perfect.
2013-11-14 20:55 <DocScrutinizer05> though often those companies can't ship what they advertise
2013-11-14 20:56 <wpwrak> or give you the "made in china" 100% compatible replacement :)
2013-11-14 20:56 <DocScrutinizer05> sophisticated form of spamming

2013-11-14 20:58 <DocScrutinizer05> of course they were not able to deliver the RAM chip I asked for, but they didn't stop pestering me with their friendly kind chinese mails
