tuxbrainwpwrak: an diode IN4007 will be ok for VTG?00:03
wpwrakgrumble: http://www.avrfreaks.net/index.php?name=PNphpBB2&file=viewtopic&t=8412200:08
wpwrakseems that i need to hack avrdude some more ...00:08
wpwraktuxbrain: better use a schottky00:09
tuxbrainIN4007 is the only one I have right now00:10
wpwrakwell, that answers the question then ;-)00:10
wpwraki don't dare to open the atmega8 data sheet to see if this would work or not :)00:11
tuxbrainok then let's use the "crossfinger" technique00:13
wpwrakjust make sure the diode points the right way ;-)00:18
qi-bot[commit] Werner Almesberger: avrdude/patches/nanonote.patch: oops, clock math was old, slightly broken version http://qi-hw.com/p/ben-blinkenlights/ea5b8af00:27
tuxbraincatothe pointing to ICSP00:32
tuxbrainthe painted side pointing the board00:33
tuxbrain(I hope so.... it's already soldered....)00:33
wpwraktuxbrain: ;-)00:35
tuxbrainwhy superglue allways glue everything else in seconds but intended pieces to glue take ages......00:40
wpwraktuxbrain: because your fingertips are more humid than the intended piece00:41
wpwrakthat was "A1:"00:42
wpwrakA2: because your definition of "intended piece" is wrong00:42
wpwrakaw_: i'm learning about taipei's new structure. seems that fedex are on the right track ;-)01:03
aw_wpwrak, new structure?01:03
wpwrakaw_: new taipei city01:04
aw_wpwrak, yeah..i see, just all cities are renamed to 'New Tapei City' where I live is.01:06
tuxbrainwell good news , arduino an NN pluged toguether an no smoke anywhere... now (well better said tomorrow) test if it works or not...01:16
rohwpwrak: hm. somehow nothing happens with the shipment.. i guess its in the 'toll booth'-circle now01:16
tuxbrainarduino (plugged at 5v)01:16
wpwrakaw_: yeah, i saw it in wikipedia. two months ago.01:19
wpwraktuxbrain: already stopping at 2 am ? :)01:20
rohsomehow i think one should add some 220 ohms series resistors into the io lines on the ubb01:20
wpwrakroh: we're having a looooong weekend with two holidays added for carnival. tomorrow will be the first work day01:20
rohnn is 3.3V for also sdio?01:20
rohcant arduino run on that also?01:20
wpwrakroh: (3.3 V on sdio) yes01:21
rohwpwrak: aaah. i see. yes. makes sense (carnival)01:21
wpwrakroh: (obsolete avr) we'll see :)01:21
wpwrakroh: (220 R) tricky - depending on what you want to do, they may get in the way01:21
rohtrue. or use 100R01:22
wpwrakroh: besides, the less protection, the more ben sales, right ? ;-)01:22
rohjust something which limits current if you get the input/output config wrong ;)01:22
rohespecially when combining 5V and 3.3V logic. maybe add some zehner diodes?01:22
rohthe (old (classic) style) was 220R on the parport ;) soldered into the db2501:23
rohsee classic wiggler schem.01:23
wpwrakroh: well, Ron is usually in the order of 100 Ohm, so that's a start :)01:24
tuxbrainroh at lest for flashing  we are attacking directly to the atmega328 chip, and I think it can be flashed at 3V3... well will see tomorow..., I'm more worried on how it will work when Arduino is powered and try to comm with it running...01:24
rohtuxbrain: if it doesnt work, lower the clock. 20mhz is not possible at 3.3V01:25
wpwraktuxbrain: should be interesting to see how the ben handles this. maybe put a resistor into MISO while you're at it01:26
tuxbrainarduino works at 16mhz01:28
tuxbrainwpwrak: maybe on V2 , V1 UBB->ICSP is already siliconed ,01:29
wpwraktuxbrain: you could make a little pcb that plugs into ICSP ...01:30
wolfspraulroh: did you see my case feedback mail?01:30
wpwraktuxbrain: what does the connector on the AVR look like ? just plain 100 mil header ?01:30
wolfspraulI just thought I write it all up...01:30
rohwolfspraul: yes i did.. just havent had the time of peace to answer it01:31
wolfsprauloh sure, take your time01:31
wolfspraulno rush01:31
wolfsprauleverything is moving, many details01:31
rohi thought i packed 8 identical screws.. but there may be some kits with mixed ones01:31
wolfspraulthe most annoying little thing is to find a way to remove the film residue in between the characters engraved in the acrylic01:31
rohfingernails ;)01:31
rohdoesnt scratch, but get off the cover01:31
wolfspraulnot with mine01:32
wolfspraulbut sure, it's solvable. just annoying.01:32
wpwrakapply suitable solvent. wipe off solvent with film ? :)01:32
rohthe alternative would be nasty stains wich need to be removed with solvents like alcohol and mechanical rubbing01:32
wolfspraulI would be worried that the solvent damaged the acrylic surface.01:32
wpwrakhence the "suitable" ;-)01:33
wolfspraulno worry, this is a small thing. I just feedback.01:33
wolfspraulit's a fact. need to manually fiddle these leftovers out of 18 characters :-)01:33
rohi used 98% alc. 'spiritus'01:33
wolfspraulfor every case...01:33
rohbut be careful.. thats correct.01:33
wolfspraulyeah so when you get to it you can reply to some of the questions, no rush01:34
rohthe protective film doesnt have any adhesive or glue.01:34
wpwrakroh: maybe peel off the film before laser-cutting, then wrap it in some film for kitchen use ?01:34
rohwpwrak: nah. same problem, even worse because you dont know how clean the kitchen film melts01:35
wpwrakroh: AFTER lasering ;-))01:35
wpwrakremove film. laser. add new protective film. ship.01:36
rohif i laser without film i get stains from the vapor01:36
wpwrakoh :-(01:36
rohthe protective film isnt there for shipping protection. its for protecting the workpiece where not lasered from dirt while lasering01:37
rohalso scratches from metal etc01:37
wpwrakah, i see. i thought it was just the usual scratch-while-in-transit protection01:37
rohi'll test a commercial laser service soon and then i'll know more details01:39
tuxbrainwpwrak: I uploaded some quick pics on http://www.tuxbrain.org/downloads/nanonote/arduino/01:39
tuxbrainthe diode is inside the amount of silicon :P01:40
tuxbrainI also have recorded the process on video01:41
tuxbrainbut it must be edited to let it no more longer than 2 mins.... actually is about 50min01:42
wpwraktuxbrain: in hot glue we trust ;-)01:44
wpwraknice pix01:44
wolfspraulnice, I like 17 the most01:44
tuxbrainI'm not very proud on how it looks, on my defense I have to say is my first contact with hot silicon glue, and I bought it today on the chinese shop for 6¬ glue included :P01:44
wolfspraulwill upload to wiki, include in news etc.01:44
wpwraktuxbrain: 50 min may be a little long, yes :) well, better than a live coverage of your 3+ days of gcc ;-)01:45
tuxbrainwolfspraul: hold on until is demonstrated it works01:46
wpwrakwolfspraul: (#17) the ben looks just as if it always belonged there - like a laptop01:47
wolfspraultuxbrain: ok sure, you know I'm super hard on news that talk about something that doesn't actually work. But given that we are on the 9th today, I thought I give you the benefit of the doubt :-)01:48
wolfspraulif it doesn't really work by the first, the news item is simply pushed forward to the next month01:48
wpwraktuxbrain: (hot glue) you may get a smoother finish with silicone paste. if you wet your finger with alcohol, the silicone will lose viscosity where you touch it and you can easily shape it01:49
wpwraktuxbrain: e.g., i did these this way: http://downloads.qi-hardware.com/people/werner/f32x/c2ben-run1.jpg01:50
wpwrakroh: it's moving ! :)01:51
wpwrakmeanwhile, in distant taipei, a driver is trying to make sense of adam's address :)01:52
tuxbrainwpwrak: but silicone is not lot more flexible?, maybe in the UBB part it sould be ok due cable is also glued with superglue but in the ISCP hot glue will avoid the soldering to suffer mechanical stress...01:52
wpwrakroh: the shipment. LLEGADA AL CENTRO DE PROCESAMIENTO01:52
wpwrakroh: that's the international processing center. if we're very lucky, they'll even put it on a plane tonight.01:53
wpwraktuxbrain: yes, good point01:54
wpwraktuxbrain: of course, one should always pull on the connector, never on the cable ;-)01:54
tuxbrainwolfspraul: tomorrow I will put all pieces toguether, avrdude, avr toolchain+arduino libs and cable.... let's see01:55
tuxbrainwpwrak: (pull on conector) yeah I aaaaalways do so.....¬¬01:56
tuxbrainn8 dudes01:56
wpwrakaw_: whee ! now, did they survive ?03:15
aw_wpwrak, i am soldering somethings. :-)  and just receive that super gift! thanks.03:44
kristianpaulit was a DIY package ?;-)03:45
aw_kristianpaul, yes..adding N-MOSFET to do experiments. :-)03:46
aw_here http://en.qi-hardware.com/wiki/Protection_of_Reversed_Polarity_on_DC_plug-in03:46
aw_still working on..;-)03:47
wpwrakaw_: yay, it made it ! :)03:47
aw_wpwrak, yeah!03:47
kristianpaulwpwrak: 1 of 3?03:47
kristianpaulor 3 of 3 already?03:47
wpwrakkristianpaul: he hasn't seen the horribly awkward flashing procedure yet ;-)03:47
wpwrakkristianpaul: 1/3. 2/3 is still in buenos aires. 3/3 is still not sent.03:47
kristianpaul2/3 stil? wow how long so far?03:48
wpwrakkristianpaul: with a little luck, 3/3 will have DFU, so i won't have to send another atusb-pgm with it. those pogo pins are kinda expensive03:48
aw_kristianpaul, wpwrak i think that now yes I haven't seen the related procedures for super gift yet...03:49
aw_meanwhile I am working for sourcing parts and experiments for M1 rc3... I am not sure I'll digging into it in short time. but it's okay i received them now.03:51
wpwrakkristianpaul: we have a very long weekend here, with the carnival. monday and tuesday were holidays.03:51
kristianpaulwpwrak: what carnical?03:51
wpwrakkristianpaul: oh, just carnival. nothing particularly exciting around here. it's not like rio :)03:52
kristianpauli see03:52
kristianpaulwpwrak: when a system lack mmu, i can say dma is just "maped"03:53
wpwrakkristianpaul: you mean identity-mapped ? yes03:53
kristianpauli should mean that..03:53
wpwrakkristianpaul: that is, unless you have a weird DMA architecture03:54
kristianpauli still understanding mm1 dma arch..03:54
kristianpaulof course it doest mean is weird, i guess is too simple and i'm just getting picky trying to understand it :-)03:55
wpwrakkristianpaul: e.g., i think the IBM PC design has a limitation on the number of bits in DMA addresses. so you could only DMA to the first something kB03:55
kristianpaulso dma is too especific for every arch and system?03:56
wpwrakkristianpaul: maybe sebastien, when facing the decision whether to make this nice and simple or evil and weird chose evil ? ;-)03:56
wpwrakkristianpaul: yeah, there's no "standard" DMA design. although most simple modern DMAs look pretty similar03:56
kristianpauli hope dont, milkymist isnt that hard to understand03:56
wpwrakkristianpaul: but you can get some fun extras, like "scripted" DMA, different views of the memory structure, iommu if you're "lucky", ...03:57
kristianpauliommu sounds fancy03:57
wpwrakit is ;-)03:58
kristianpaulwpwrak: does ti look related to dma https://secure.wikimedia.org/wikipedia/en/wiki/File:Wishbone_cross_bar.jpg04:14
kristianpaulOr may be i'm confusing a part of the wishbone as dma..04:14
Action: kristianpaul look ar larsc for some comments :-)04:15
wpwraki guess dma could be one of these entities, yes04:19
wpwrakor it could also sit somewhere inside the ip core04:19
wpwrakerr, master04:19
wpwrakgrmbl. now that silly avr-glibc tells me the atmega32u2 has no boot loader support ! rubbish. of course it has !04:20
kristianpaulok, acording to the mico32 cpu ref manual, CPU is master 1 in a shared-bus arbiter04:21
kristianpaulok i think i have more clear path for reading tomorrow04:23
kristianpaulnite all04:23
Action: kristianpaul dont give nite to wpwrak as he never sleep04:23
larschmpf... the jz4760 dies when i try to access vmalloced memory :/04:24
wpwraki only suspend ;-)04:25
wpwraklarsc: no mmu ? ;-)04:25
larscwpwrak: hm, maybe i used the vpu by accident instead of the cpu ;)04:26
kristianpaulok, wikipedia vpu article was not wat i was waiting for, at least larsc means the vpu is a virus  :-)04:27
larsckristianpaul: video processing unit04:31
larscmaybe now is a good idea to add jz47xx support to openocd04:32
wpwraksigh. not even avr-libc 1.7.1 has it :-( i'm always amazed by how little actually works in certain areas of our little free software universe ...04:38
wpwrakhmm. interesting. this actually ought to work. now.. where's the bug this time ....04:44
wpwrakaah ! my bad. i fail in the dependencies, not the compilation. subtle :)04:45

tuxbrain_awaymmm seems than the avrdude in the standard repo is not the patched one....09:03
tuxbrain_awayok here it is  http://downloads.qi-hardware.com/people/xiangfu/packages/avrdude_5.10-1_xburst.ipk09:09
tuxbrainwpwrak:  :( first test not going very well...09:57
tuxbrainwpwrak: im using the following command avrdude -v -v -U flash:w:applet/Blink.hex -V -F -C /etc/avrdude.conf -p09:58
tuxbrainatmega328p -c nanonote_ICSP09:58
tuxbrainif I execute it with the board unpowered , NN shuts down , when "avrdude: Calibrating delay loop..."09:59
tuxbrainif I execute it with the board powered http://pastebin.com/nwQAXbTA10:01
tuxbrainbut the flash didn't happen...10:02
Action: tuxbrain triying to flash directly the chip out of the board...10:07
wpwraktuxbrain: (initial problems) that's normal :)10:15
wpwraktuxbrain: you also need -e10:16
wpwrakand why -F ?10:16
tuxbrainwpwrak:  (-F) dunno was the Makefile I used on debian with NN uart10:18
wpwrakdevice signature 0000 means that communication didn't happen10:18
tuxbrainmmm only with the chip it also shuts down at same point10:20
wpwrakif the ben shuts down, maybe the capacitative load is too large. in this case, try adding a delay in avrdude-*/nanonote.c:nanonote_powerup before the gpio_low10:21
wpwraksomething like  sleep(1);10:21
wpwrakmaybe check the signals with a scope. i.e., that reset has a long pulse, that sclk has something that looks like a clock, that mosi has something that looks like data, and that miso at some point in time has something that looks like data, too10:30
tuxbrainwpwrak: no scope at hand :(10:32
dvdkany news about UBB? already shipped?10:38
tuxbraindvdk: yes it should arrive today or tomorrow10:38
Action: dvdk needs to know in advance, because he usually pretends to not be home when the bell rings10:39
tuxbrainmmmmm executing it unplugged also shuts down.....10:40
tuxbrainmmm without the cable it doen't shut down so somethings wrong with the cable :(10:45
wpwrakdvdk: hehe ;-) i often do that, too :)10:56
wpwraktuxbrain: did you  echo jz4740-mmc.0 >/sys/bus/platform/drivers/jz4740-mmc/unbind10:57
wpwraktuxbrain: (before doing anything else; needed after each ben reboot)10:57
Action: roh needs to get his nn working again first10:59
rohi still only got that dead old thing with only half the flash or so10:59
kyakxMff: may i remind you about the libglade patch that fixed the build problem? :) http://dpaste.com/481917/10:59
kyakxMff: the error can be seen also from buildhost build: http://fidelio.qi-hardware.com/~xiangfu/compile-log/openwrt-xburst.full_system-03082011-1900/BUILD_LOG.03082011-2059.last10011:02
tuxbraindamn the echo thing does the nn not to shutdown :)11:10
tuxbrainarduino power brigt for a moment the pin13 led (sck) also blinks for brief instants but seems there is no flashing and avrdude output is the same as the powered board test11:16
tuxbrainIT WOOOOOORKS!!!!!!!!!11:47
wolfspra1lthat's clear :-) congrats!11:48
tuxbrainha! it works even on a powered board!!!11:48
tuxbrainworks unplugged and works plugged !!!11:48
jow_laptopkyak: moment11:49
tuxbrainwpwrak: btw you have a mistake on the 8:10 pin out comments on avrdude.conf11:49
tuxbraincmd =6   not 511:50
jow_laptopkyak: done11:54
kyakjow_laptop: thnkas!11:55
kyakjow_laptop: finally, there is a package (libxfce4util) that failed to build, and updating to a newer version + removing libtool fixup made it built! Some developers do learn.. I'll update other packages from feeds/xfce accordingly11:55
tuxbrainardunote era has arrived! (bwahahahahaahaha!)11:57
tuxbrainwpwrak: there is a way to flash bootloader+program?12:03
kyakjow_laptop: finally, config.full_system has built. Please accept this patch: http://dpaste.com/482391/12:24
jow_laptopkyak: does the newer xfce stuff not use libtool anymore?12:36
kyakjow_laptop: it uses libtool, but doesn't need the fixup (it fails with the fixup)12:38
jow_laptopkyak: problem with shipped libtools is that they're often not cross compiel safe12:39
jow_laptopkyak: it often fails on ppc for example12:39
jow_laptopeither it wants to link the host libc or relink into /usr/lib12:40
kyakjow_laptop: i don't see any warnings about "unsafe include path for cross-compilation". Does it mean it's ok??12:41
jow_laptopkyak: not really, we had the case where libtool compiled fine for brcm47xx but failed for ppc44x12:41
jow_laptopwithin the same environment12:42
kyakah ok12:42
kyakwith this fixup in place, there are many and many warnings about missing marcos etc...12:42
jow_laptopcan you show me?12:43
kyakwhen i try to patch configure.in, it ends up being unable to find glib.h12:43
jow_laptopwe remove aclocal.m4 by default12:43
kyakok, one momment12:43
jow_laptopsome packages have their required macros in there12:43
jow_laptopwithout having an extra m4/ or acinclude.m412:44
jow_laptopif this is the case for xf* try PKG_REMOVE_FILES:=12:44
jow_laptopit defaults to :=aclocal.m412:44
jow_laptop(reason for removing aclocal is that packages have a full copy of libtool.m4 in there which in turn has a full copy of ltmain.sh embedded which in turn overwrites whatever we patch...)12:46
kyakyeah, i foudn at least one missing macros in default aclocal.m412:49
kyaktrying with PKG_REMOVE_FILES:=12:49
kyakit didn't change anything12:50
jow_laptopcan you paste the log?12:51
kyakthe generated aclocal.m4 is missing it.12:51
jow_laptophm it shouldn't generate it in the first place...12:52
jow_laptopat least if it exist already12:52
kyakthis is the build log12:59
kyakthe aclocal.m4 from tar ball and build dir  are differenet13:00
jow_laptopI think the proper fix is to ship the xfce dev tools13:00
jow_laptopwe did the same for gnome and xorg13:00
jow_laptopfun, it uses autoconfig to ship autoconfig macros13:03
jow_laptopI'll take a look13:03
jow_laptopmight take a while though to compile the whole needed stack for xfce13:04
kyakok, thnaks13:07
jow_laptopkyak: please try this: http://dpaste.com/482513/13:14
jow_laptopkyak: make tools/xfce-macros/install V=9913:14
jow_laptopkyak: make package/libxfce4utils/{clean,compile} V=9913:15
kyakMakefile:32: *** missing separator.  Stop.13:25
kyakit is make tools/xfce-macros/install V=9913:26
jow_laptopoh might be copy & paste13:26
kyaksome warning and the error13:31
kyakpasting th elog...13:31
jow_laptopkyak: svn revert -R tools and try to re-apply13:34
jow_laptopkyak: I suppose there was bitrot from the previous patching attempt13:34
kyakah hm, i reverted the patch with -R :)13:34
kyakok, i git checkouted tools13:36
kyakapplied the patch13:36
kyaklet's see13:36
kyakxfce-macros installed fine13:38
kyakjow_laptop: libxfce4util built fine!13:40
jow_laptopcan you check xfconf too?13:40
jow_laptopI still get an error in libxfce4util13:41
jow_laptopGTK_DOC_EXTRA_CFLAGS undefined13:41
kyaki use 4.6.113:42
kyaki.e. no patches for libxfce4util13:42
jow_laptopah no, the xfc4-dev-utils I just packaged seem too old13:43
jow_laptopthey lack XDT_SUPPORTED_FLAGS13:43
kyakxfconf just built fine, too13:45
kyakthanks a lot!13:45
kyak(i have no idea btw why we have those in image)13:45
kyakmight be a weird dependency of something13:46
jow_laptopI cannot find the current upstream of the xfce4-dev-tools13:46
jow_laptopthe first google hits points to some page that was last updated in 200713:46
jow_laptopxfce.org :P13:47
kyaknow.. seems that we will have to survive another merge of backfire13:48
jow_laptopthere should be no big changes anymore13:50
jow_laptopfrom which tree is your libxfce4util ?13:52
jow_laptopmine behaves completely different...13:52
jow_laptopits from svn.owrt.org/openwrt/feeds/xfce13:52
jow_laptopis there a copy in Qi packages?13:52

viricI think that I could run staroffice back in the late 90s with 24MiB of RAM.14:02
viricDo I have a distoted memory?14:02
kyaki do rememeber running MS Office 95 or something on Pentium 75 Mhz with 32 Mb RAM14:04
viricthe software industry is totally mad then :)14:04
viricWhy are we nowadays that far from that?14:07
tuxbrainwolfspraul: you are save now on adding to news than NN has become an portable avr/arduino compiler/flasher ,14:09
tuxbrainupdate your microcontroler while listen your favorite music :P14:09
virictuxbrain: with the UBB boards?14:10
viricnice ):14:12
virichow big is the intersection of nn users and arduino users?14:12
tuxbrainwith board powered and unpowered, now I gonna test just the bare chip, but all is pointing to this is also totall feasible14:12
viricon an unrelated topic...14:14
viric'gmenu2x' is the only program of "that kind", right?14:14
viricsome kind of program menu/file browser/ for SDL14:14
wolfspraultuxbrain: you are selling bare arduinos, are you also selling shields?14:16
wolfspraulwhich shields sell best, or you think which shields sell best at other arduino shops (if you don't sell them)14:16
tuxbrainethernet and motorshield14:17
wolfspraulok nice, very clear14:18
virictuxbrain: do you supply universites or any other studying institutions?14:18
tuxbrainsome but not really big orders , the most 20 units, but I feel growing interest on secondary schools on arduino platform.14:20
rohwpwrak: the boards you sent.. they are preprogrammed/have a bootloader?14:32
rohor how do i flash em?14:32
tuxbrainwpwrak: flashing the chip alone fails..14:55
tuxbrainwhere the VTG(VDD on 8:10)  has to be connected on ... on VCC on the chip?14:58
tuxbrainit  fails on signature15:01
tuxbrainavrdude: Device signature = 0x0f000215:01
tuxbrainavrdude: Expected signature for ATMEGA328P is 1E 95 0F15:01
tuxbrain         Double check chip, or use -F to override this check.15:01
tuxbrainand with -F fails on flash verification15:02
tuxbrainwpwrak: mmm on chip only the device signature give random numbers...15:23
tuxbrainbridging VCC and AVCC doen't help15:30
tuxbrainplugin just AVCC pass the device signature but fails in flash verification and also complains about fuses missmatch15:38
tuxbrainwpwrak: need schematic or a clue on what pins you have connected VDD on Atmega48 to figure out where to plug them on Atmega328, for the moment ardunano will start with flashing on board only :)16:12
kristianpaulnanomap segfault .. :-(16:19
wpwrakroh:  they have a basic firmware. the boot loader doesn't work yet :)16:49
rohah. there is isp on it?16:53
wpwrakroh: there's even a ben-atusb cable16:54
rohwpwrak: whohoo17:53
kristianpaultell us !!18:01
tuxbrainwpwrak: have you read my questions?18:03
Action: kristianpaul discovers the usefullness of screen -x19:34
Action: Jay7 is always using screen -Ax19:40
virickristianpaul: I recommend you 'tm' :)19:43
wpwraktuxbrain: (Qs) checking ...20:12
wpwraktuxbrain: first, congratuations !20:19
wpwraktuxbrain: (how to flash bootloader) i'm experimenting with this these days. maybe have a look at ben-wpan/atusb/fw/Makefile20:20
wpwraktuxbrain: not entirely sure if it really works yet, though20:20
wpwraktuxbrain: (bug0 oh, right. thanks !20:20
kristianpaulviric: (tm) ohhh!  :-)20:21
wpwraktuxbrain: (chip) hmm, is the chip used to start with the internal clock ?20:22
virickristianpaul: it's for sure a great tool! ;)20:23
kristianpaulviric: tm is tmux in debian?20:25
kristianpaulah mixer20:25
viricit's not in debian20:25
kristianpaulno multiplexer20:25
kristianpauleven better ;-)20:25
wpwraktuxbrain: (chip) also, there are often several VDD and GND. are they all connected ? not sure what the chips really require20:27
virickristianpaul: only nice distributions have 'tm'20:27
qi-bot[commit] Werner Almesberger: avrdude/: fixed confusing typo in avrdude.conf, added tuxbrain's nanonote_ICSP http://qi-hw.com/p/ben-blinkenlights/6ef2b3920:36
kristianpaulviric: the eth/mac mode is awesome !20:37
kristianpaulIt was code from sec?20:37
viricI don't know sec20:37
virickristianpaul: from 'cec', yes20:38
kristianpaulcec sorry !20:38
viricwell, I had to modify that code a lot :)20:38
viricbut I used it, yes20:38
kristianpaullol Thanks "To GNU, an ugly but working and helpful ol' UNIX implementation. "20:38
viricDon't you agree? ;)20:39
kristianpaulhelpful yes20:39
kristianpauli cant speak about the ugly, may be i still so newbie ;-)20:39
Action: kristianpaul looks at wpwrak 20:40
virichow many gnu code you tried to dig in? :)20:40
viricno wonder.20:40
kristianpauli diged in on busybox once :-)20:40
virickristianpaul: from the same factory you may like http://vicerveza.homeunix.net/~viric/soft/ts/20:40
wpwrakoh yes, definitely ugly20:40
wpwraktwo spaces for indentation. blargh :)20:41
viricwpwrak: when lisp writers go to C...20:41
kristianpaulviric: i lied, i look at coreutils once, and yes that was just before i was getting busybox code ;-)20:43
virickristianpaul: hehe :)20:43
dvdkgot my shipment of 50 UBBs today20:45
dvdkcan anybody give me an accurate number for the weight/UBB?20:45
dvdkapproximately 1g/UBB, but don't have a digital scale here20:46
dvdk(need it for calculating the postage to pay)20:46
wpwraktuxbrain: (ubb) ah, did you send mine with ups ? did they give you a tracking number ?20:47
wpwrakdvdk: they measure by a single gram ? wow20:48
dvdkwpwrak: mine came with ups today, but wrapped in an envelope, just thrown into my mailbox20:48
dvdkwpwrak: on an old mechanical scale, accurate to 20g20:48
dvdkput all 50 on it.20:48
dvdktake it with a grain of salt20:49
wpwrakdvdk: (ups but not like ups) interesting :)20:49
dvdkwpwrak: you're the expert.  what is the specific weight/m^3 of the .8mm board material used?20:51
dvdkand what is the total area of one board? :)20:51
wpwrakdvdk: puah ;-) a home-made UBB is 0.50 g20:51
wpwrakdvdk: three without tin are 1.51 g20:52
wpwrakdvdk: not sure how much the solder mask and the silk screen add. probably not a lot20:52
wpwrakah .. one without tin but etched: 0.47 g20:53
wpwrakand two without tin and unetched: 1.04 g20:53
wpwrakso probably ~ 0.6 g for an "industrial" UBB20:54
wpwraki.e., the real weight is in the envelope :)20:54
kristianpauldvdk: you live in germany?20:55
kristianpaul(have a feeling)20:55
kristianpaulha i knew it !20:55
dvdkkristianpaul: judging from you name, you're too? :)20:56
kristianpauldvdk: i dont20:56
wpwrakkristianpaul: what gave it away ? the .de at the end of his domain ? ;-))20:56
kristianpaulwpwrak: he, i wanted to confirm :-)20:56
dvdkheard my german accent? :)20:57
kristianpaulI still wonder you have to pay per gram20:57
kristianpauldvdk: I just noticed on this channel, well, all the regulations in germnay20:58
kristianpauldvdk: Thats why asking :-)20:58
viricpay? gram? What is this about?21:01
Jay7they are selling LSD over UBB sheets :)21:02
Action: Jay7 hides21:02
kristianpauldvdk:In you mplayer experience on the nanonote, already tried ogv?21:04
viricdvdk: ah, you were doing the GPU code, right?21:06
viricdvdk: my personal congratulations. That's the kind of work I like to see!21:06
wpwrakJay7: i was about to comment that i was wondering if they weigh their shipments in colombia by grams, too ;-)21:08
dvdkkristianpaul: *only* tried ogv (theora)21:08
dvdkviric: thanks, just i'm very constrained on time currently (kind of weekend project), this is going to take a few more weeks.21:10
Action: roh sees custumers licking their ubb in the hopes of being one of the 'the lucky 25' ;=)21:10
Action: tuxbrain is liking the boards first if so :P21:11
tuxbrainwpwrak: still no pdfviewer?21:12
kristianpaulwpwrak: i'm lucky, for postal mail before 2kg i'm free of paying tax and handling :-)21:14
tuxbrainwpwrak: (shipping) I will do tomorrow, my daughter is on vacation and I can't go to postal office, tomorrow she will be out all day so I will send to you(50) , kristianpaul(10) and rjeffries(10)21:15
tuxbraindvdk: Do you like them?21:15
kristianpaultuxbrain: (send) oh great, how much i must pay first? ;-)21:15
dvdktuxbrain: the ubbs?21:15
dvdkvery nice.21:16
tuxbrainkristianpaul: due I don't know in advance how much the shipping will cost , I will ship and send you the proforma then21:16
kristianpaultuxbrain: (glup) ok !21:16
tuxbrainmth:any advance in packaging the avr toolchain?21:18
tuxbrainkristianpaul: (glub)?21:18
tuxbrainwpwrak: atben/atusb gervers and bom in windows readable format?21:20
kristianpaultuxbrain: glup = me be prepared to pay whatever ;-)21:21
tuxbrainwpwrak: I will ask for quoting 100 units of each to make them here in spain.21:21
kristianpaultuxbrain: just pcb? or also SMT ?21:22
tuxbrainkristianpaul: 30¬+shipping (no more than 15¬ I guess)21:22
tuxbrainkristianpaul: also smt21:22
tuxbrainand if roh find a solution, even box/envelop21:23
tuxbrainfinal product :)21:23
kristianpaulwait for adam comments about ubb is proper i would suguest21:24
kristianpaulof course, not saying you can lead the run this time :-)21:24
tuxbrainalso if some one is motivated enough to make an WPAN shield for arduino I will also love to work to include in the catalogue, we(qi-hw) can be the  first to put 6LowPan seriously on market21:26
viricingenic started publishing the manuals?!21:27
viricI can't access there21:27
tuxbrainkristianpaul: of course Adams words are gold21:27
tuxbrainkristianpaul: but to have an idea on costs, actual state can be good enough.21:28
kristianpauli agree21:28
Action: kristianpaul may try atben/atusb PCB manufactuing with local company21:29
tuxbrainkristianpaul: if you achive same price ration as with the MM1 cases, I will buy directly to you :)21:30
kristianpaulhe, lets see :-)21:30
rohviric: same here21:35
viricdvdk: what documents are you following for the GPU?21:37
dvdkviric: have a look at the header of teh source code (svn on sourceforge)21:38
kristianpaulviric: roh http://www.openmobilefree.net/other/Ingenic_Docs/ftp.ingenic.cn/2soc/21:38
wpwraktuxbrain: i can make the gerbers tomorrow. today, we have a little asado, so i'll be busy soonish. for the bom cost ...21:38
kristianpaulwpwrak: make gerbers = export gerbers from kicad right? anyway, i just fill the form and send all data this company ask21:39
viricdvdk: I'll wait for the answer to come :)21:39
viricI have time21:39
wpwrakkristianpaul: yeah, output gerbers, dxf for the outline, and zip/tar them all together21:39
virickristianpaul: the connection does not work21:40
kristianpauldxf out, ok21:40
wpwraktuxbrain: (boms) http://pastebin.com/EqUTxZ4F   (pricing from digi-key, 100 pieces each)21:40
kristianpaulviric: dns are slow21:40
virickristianpaul: I have the openmobilefree.net resolved21:40
kristianpauli dont :(21:42
viricconnection to www.openmobilefree.net ( could not be established.21:45
kristianpaulwpwrak: hi21:47
viricI just wrote a program that reports (finally) interesting numbers about memory usage in prcoesses22:20
mthtuxbrain: I don't know, I'm not involved in the avr toolchain22:45
tuxbrainmmm isn't you that offer to make a proper port to openwrt? I will review the logs, sorry dude22:46
xMfftuxbrain: that was me22:50
virickyak: you cared on memory usage, isn't it?22:50
tuxbrainxMff yeah!! how it's going?22:52
xMfftuxbrain: did not get very far yet22:54
xMfftuxbrain: mainly due to other projects, but I intend to look into it during this week again22:54
tuxbrainxMff: at least we know at the end it will work :)22:55
virichm c++ compiling in the nanonote...23:20
viriccross fingers23:20
viricno way23:33
Jay7viric: try to compile boost ;)23:49
Jay7I just wonder how much time it may take :)23:49
