<wpwrak_> DocScrutinizer05: ooh, you rolled back to 255 ? damn 8 bit counter registers
<DocScrutinizer05> huh?
<DocScrutinizer05> well, usual undo for bogus donations
<DocScrutinizer05> somebody hit "send" twice, or 4 weeks ago somebody donated and CC finally didn't transfer / did reject
<DocScrutinizer05> or money transfer didn't arrive after 4 weeks or whatever
<DocScrutinizer05> Pledged: 53425.00 EUR Received: 52575.00 EUR -- click on "255 devices"!
<DocScrutinizer05> >>subject to corrections for cancelled/rolled-back transactions<<
<wpwrak_> yes yes, i know. it's just funny to see it dance around the "magic" 1 << 8 :)

<DocScrutinizer05> dnag! tapping the SIM data lines between modem and SIM voids the FCC approval
<DocScrutinizer05> so **we** can't do that
dos1 has joined #qi-hardware
<DocScrutinizer05> which is so old it already collected sufficient dust to make the SIM inoperable due to contact problems
<wpwrak_> i see ... i see ... a few "0R DNP" :)
<DocScrutinizer05> me too me too
<DocScrutinizer05> :-D
<DocScrutinizer05> actually, those 0402 R footprints are pretty confusing when 2 R are parallel to each other ;-)
<wpwrak_> "for diagnostic purposes" :)
<wpwrak_> yeah, they are ;-)
<DocScrutinizer05> you never can tell from the footprints which orientation the Rs are supposed to be
<DocScrutinizer05> though we need a level shifter

<larsc> apelete: your patch got merged upstream as a christmas present :)
<pcercuei> nice :)
<apelete> saw the usb driver got merged for 3.14 indeed, hooray :)
<apelete> larsc: now I'm waiting for the mips platform data patches to get merged too
<apelete> musb driver feature won't be complete without those
<apelete> larsc: are you back from holidays already ?
<larsc> no, I'm at the 30c3 at the moment
<apelete> what's 30c3 ?
<larsc> the MIPS patches will be merged, I know the person who takes care about this
<larsc> chaos communication congress
<apelete> didn't knew about that event, thanks for the link
<larsc> last day today
<apelete> nice. got back from Paris yesterday, got a couple of holidays left before going back to work
<DocScrutinizer05> hmm, is there a multiplexer design that does A<->Out for Control=1, B<->Out for Control=0, but A<->Out<->B for Control=highZ ?
<apelete> larsc: didn't have time to work on the nanonote during the week :-(, did a lot of work on the family servers instead :-)
<apelete> I hope to get back at it this week
<larsc> I didn't even pack my nanonote
<apelete> ha ha :)
<larsc> but somebody gave me one of werners wpan modules
<larsc> here at the congress
<apelete> nice
* DocScrutinizer05 ponders a nifty combination of MOSFETs
<wpwrak_> larsc: only one ? will be hard to find something to talk to then
<larsc> wpwrak_: yea, a friend said he'll send me a usb dongle
<wpwrak_> DocScrutinizer05: use two control lines ?
<DocScrutinizer05> too obvious
<apelete> larsc pcercuei: I bought a gcw-zero from qbertaddict on #gcw, things should get even more interesting (and busy) soon
<DocScrutinizer05> some " 1 1: Not Defined, do not use!" will not suffice ;-)
<wpwrak_> btw, i threw the reverse-voltage protection FET out of anelok. not only did it produce that mystery resitance to GND but i also realized that it could make low battery situations worse by throttling the battery
<DocScrutinizer05> reverse voltage protection is always a pain. Only feasible concept: fuse plus clamp diode
<wpwrak_> one positive feedback loop into disaster less :)
<wpwrak_> well, cr2032 can do it mechanically if the + contact is on the side and not on top
<DocScrutinizer05> sure
<DocScrutinizer05> already wondered what for you need that
<DocScrutinizer05> btw for a CR2032 you don't even need a fuse
<wpwrak_> the only risk would then be that the circuit may not like VBAT to be shorted to GND, which is something you could still sneak past a mechanical barrier, at least for a short moment
<DocScrutinizer05> Z is high enough already
<wpwrak_> yeah, Z kinda sucks :)
<apelete> <larsc> the MIPS patches will be merged, I know the person who takes care about this
<apelete> I guess you're talking about Ralf Baechle, do you know how he manages his tree ?
<DocScrutinizer05> I guess a CR2032 must have several dozen Ohms ESR
<apelete> larsc: I mean, do you think the patches will be merged for 3.13 or 3.14 instead ?
<apelete> 3.13 is already at rc6, and 3.14 merge window will open in mid-january it seems
<larsc> apelete: ralf is afk for a while, but blogic is taking care of the MIPS tree at the moment
<larsc> blogic asked me if it is ok to merge the patches for 3.14 so I assume they'll be merged
<apelete> awesome, thanks for letting me know
<wpwrak_> DocScrutinizer05: about 20 while it's >= 50% full. the it rises slowly to 40, and then skyrockets in the last 10% or so
<apelete> larsc: ok, so I'd better let the process goes on and move onto adding dma for the MMC driver as we talked about
<DocScrutinizer05> cool
<DocScrutinizer05> max reverse charge: 1uA. LOL

<DocScrutinizer05> hmmm, not really exciting

<kyak> no, he tricked you into thinking that he is more of a sambo. Typical judo thing!
<viric> ha, crazy war arts
<wpwrak_> yet another electrical substation went up in flames. since nobody could be bothers to turn off the electricity, the firefighters have been waiting for some 1.5 hours without doing anything.
<wpwrak_> that's .. hmm, within walking distance from my place.let's see if i can see the smoke
<viric> I remember here when snow made some mid-tension cables fall
<viric> electric fire on snow for hours
<viric> And I guess that earth potential difference between your legs could kill you, if you weren't careful
<wpwrak_> nothing to see
<viric> "nada que ver"? :)
<wpwrak_> heh :)
<wpwrak_> i was looking for the smoke column. but maybe they extinguished it since. that video is from one hour ago.
<wpwrak_> ah yes, in the second video, 30' later, the smoke is already almost gone

<JewFro297> Does the wishbone interconnect support connections between multiple clock domains?
fire has joined #qi-hardware
<JewFro297> That's quite a depressing mistake
<whitequark> that is a whole list of mistakes...
<JewFro297> I kept reading... Those are really depressing mistakes
<whitequark> fortunately I'm using a chinese clone of the board
<whitequark> somehow they were able to get it right on version 1.0
<JewFro297> LOL
zrafa has joined #qi-hardware
<JewFro297> maybe because they designed it to the advertised specs
<wpwrak_> it's bad if the clones are earlier and better than the original ;-)
<whitequark> well, iteadstudio (the company who cloned the board) seems to have rather competent engineers in general
<whitequark> guess they can't afford incompetence!
metalfreak has joined #qi-hardware
<metalfreak> hi
<JewFro297> Sup
<zrafa> kristianpaul: hey
<zrafa> kristianpaul: how are you?
<wpwrak_> hmm. screen dump from my scope: black signals on a black grid with a black background.
<JewFro297> Seems legit.
<JewFro297> Anyone know of a good cheap (and I mean really cheap) logic analyzer?
<whitequark> buspirate?
<wpwrak_> a few leds ? :)
<JewFro297> Buspirate is pretty, but only appears to support serial transactions
<JewFro297> Then again, it's still more useful than nothing
<DocScrutinizer05> those 200bucks USB-"scopes" usually come with 8bit TTL level logic analyzer
<DocScrutinizer05> 8bit since that's their internal storage width for the scope signal
<DocScrutinizer05> aka "resolution"
<JewFro297> I think there's actually a soft one that Altera has for their FPGAs... I'll have to look into that
<whitequark> JewFro297: the question is how high frequency do you need
<JewFro297> Probably 100MHz. Then again, I might not need anything. It's more of a want
<whitequark> 100MHz is a lot
kanzure_ is now known as kanzure
<JewFro297> Yeah, I think it's a lost cause to get something cheap with said capability.
<DocScrutinizer05> those 20bucks USB thingies are usually up to 20MHz
<DocScrutinizer05> iirc
<DocScrutinizer05> 200bucks even
<whitequark> http://www.saleae.com/logic16 is $300 and can sample 2ch at 100MHz
<whitequark> dunno if it fits your definition of cheap

<JewFro297> Hmm, actually that looks pretty nice

<whitequark> their software is seriously great
<whitequark> especially on *nix

<habs> I'm thinking about buying a Nanonote from Pulster, but I have a few questions before I take the leap. First, are there any firmwares on the Nanonote that aren't free software yet (wheter it be NAND firmware or EC firmware)? Second, as I understand it the Nanonote doesn't come with a wireless card. What would be a "good enough" wireless card I could buy for the Nanonote that runs with a free firmware?
<habs> Third, how active is the Nanonote community today? Thanks.
<ysionneau> wpwrak_ is often doing some nice hacks with the SDIO port
<whitequark> habs: I don't think there is any non-free firmware on Nanonote at all
<ysionneau> and larsc apelete and maybe others are maintaining/improving/bugfixing the nanonote kernel
<whitequark> or actually any firmware except the code running on CPU
<wpwrak_> (fw) well, the cpu has a boot rom that's closed ...
<habs> Well, I'm pretty sure you guys' quick response times answered my thrid question; thanks
<ysionneau> ;)
