tuxbrain_awaywpwrak: need the files, I have no f&7ing idea on how to generate them, I never see any cad/cam software apart of autocad14 in tech drawing practice at school ... 15years ago.09:02
tuxbrain_awaywpwrak: send me an email I will be not online all weekend09:05
wolfspraulkyak: I want to try to get keyboard and mouse usb gadgets to work, so the ben can act as a controller for milkymist one10:07
wolfspraulbut I think they don't even exist in kernel.org yet :-)10:07
kyakwolfspraul: yeah, there is only limited number of usb gadget drivers, at least what i see in 2.6.3210:28
kyakwolfspraul: there is usb audio gadget, which (theoretically) could "forward" Ben's ALSA outpust via USB to a host PC. So Ben would act like USB audio card10:29
kyaki don't know the use case, but sounds fun :)10:29
B_LizzardWell, better than buying a USB sound card10:31
B_LizzardI guess it could be useful for people who do mixes and need two different outputs10:31
kristianpaulwpwrak:( make gerber) I cant be much thankful and happy, i hope tuxbrain_away too :-)11:07
kristianpaulwpwrak: : well, i need apply wolfspraul patches, but thats a worth task for sure11:07
kristianpaulwolfspraul: nanonote and milkymist (hid way), it sounds good but is not a bit ironic when you miss the the LCM part ;-), well i think11:14
kristianpaulI agree is a valida accesory11:14
wolfspraulI'm embarassingly behind on those. first the new bugs/features from werner, then my proposal for upstreaming which I never followed up on. argh.11:14
wolfspraulkristianpaul: maybe this is helpful http://en.qi-hardware.com/wiki/Server_setup#KiCad11:15
wolfspraulthe wolfspraul patches are merged with the wpwrak patches, so it's only 1 patchset actually11:15
kristianpaulkyak: (semn audio) there is person working asking and working on that path, and asked here several times, i hope he read the backlog :-)11:16
kristianpaulah, are/were two patches... ok, i'll check wiki page you pointed11:16
kristianpaulwolfspraul I was organizing the buy group last week, after around 10 person a i mailed wich we're interested or tell me i want one, just 2 confirmed :/ what a shame... but thats how it works11:29
kristianpaulI dont give up, but rely on people to buy stuff is really hard..11:29
kristianpaulI imagige if just mail then saying. hey i have this pocketcomputer, you want to buy it? what the response will be in this case..11:30
wolfspraulkristianpaul: you mean NanoNote group buy?11:48
kristianpaulwolfspraul: yeah11:49
kristianpaulFeels bad when two or three people said, hey sell me one... and response. oh well. we need arrange buy group..11:49
kristianpaulI still trying11:49
wolfspraulyou cannot force things beyond a certain point. Just advertise yourself as the copyleft hw guy in Colombia, slowly some truly good contacts will emerge.12:04
kristianpaulyeah sure12:05
kristianpaulwolfspraul: actually we have guy contact here, woakas !12:10
kristianpaulHe  is interested on buy a nanonote, that i cant sell, i wonder he already managed to get it in other way?..12:10
kristianpaulsome comparisos about xbusrt sie and ARM iMX233 from freescale http://groups.google.com/group/linuxencaja/browse_thread/thread/bf6d9751d6824d3012:35
kristianpaulsaving some readings12:35
kristianpaulddr is cheap12:35
kristianpaulboot from SD also instead of nand chips12:35
kristianpaulusb host..12:35
kristianpauldunno if he included also documentation comparison, will be nice to know :-)12:36
bartbeskristianpaul: we can already boot from "8:10"12:48
kristianpaulbartbes: sure :-)12:51
kristianpaulbut that port is really used in other tasks..12:51
kristianpaulalso you still need cpu boots12:51
bartbeslike equipment only 3 people have12:51
kristianpauland thats is only posible from nand and usb12:52
kristianpaulno more..12:52
bartbesoh you mean getting the bootloader from sd?12:52
kristianpaulhmm dma is like using pointers.. ¿?13:29
Jay7kristianpaul: iirc, alike13:53
Jay7you instruct device where to get data from RAM13:53
kristianpaulJay7: but the device can tell me also  where it is storing the data in RAM?13:59
Jay7kristianpaul: may be.. imho, it depends on device.. but better to ask some HW guy :)13:59
kristianpaulyes i depends... oh .14:00
wpwrakkristianpaul: (fab files) i have a semi-finished process for making a tarball/zip for atben. need to do it for atusb, too.14:02
wpwrakkristianpaul: (semi-finished) what's missing are the files for SMT, and of course suppressing the edges14:03
wpwrakroh: hmm, is mail.openmoko.org down again ?14:14
rohdunno. some atomic powerplant exploded.. world's going down15:51
rohseems down.15:54
kristianpaulroh: i remenber a saw an old movie once about a big nuclear cloud wich spread around globe.. and x-|16:03
kristianpaullast country to staya live was autralia16:03
kristianpaulpanic ! ;-)16:03
Jay7this world is coming to EOL16:19
Jay7another world would be created and this would be destroyed :)16:20
Jay7we are under garbage collector ;)16:20
kristianpaulnice article lekernel16:21
lekernelotoh I read another source that says Japan declined the coolant shipment offer from the US16:22
wpwrakkristianpaul: that was a lovely movie16:22
rohlekernel: the whole thing is bogus.16:22
rohthe 'cooling shipment' thing. its cooling with water.. wtf.16:23
lekernelthat's what the link I posted says: they might want to add boron (which would be shipped from the US) to stop the reaction faster16:23
rohthey should already have bor-acid on site before16:24
rohbut its too late now.16:24
lekernelwho knows, maybe they had a leak or something16:24
wpwrakroh: apparently, they have the acid available16:24
rohsince they had sinking coolant levels i would say they for sure have a leak16:24
rohthe only one constantly lying seems to be the japan goverment. 'soviet style information management'16:25
wpwrakroh: (water) depends a bit on what you're cooling. if it's the outside of the primary containments, it think the more the merrier16:25
rohif you ask me, it sounds much more like tschernobyl than like 3mile island. especially since the explosion destroying good parts of the external containment16:26
Jay7seems they really have leak16:28
Action: Jay7 is looking to news sites16:28
rohthey are leaking long before the explosion. i mean.. missing cooling water needs to go somewhere. also they were measuring cesium in  the atmosphere before i went to bed... like 10 hours ago16:29
Jay7they evacuating people from 30km zone around16:29
wpwrakroh: i wonder what the cesium meant. was it just that they vented stuff from the primary system into the secondary ? or an uncontrolled escapement from the primary ?16:35
lekernelroh: at least, the confusion and lack of information in the news sure does look like chernobyl16:36
wpwrakroh: ah, and any chance imap.openmoko.org may survive the apocalypse ?16:36
lekernelwe don't even know what exactly exploded... is it such a difficult thing to find out?16:36
wpwraklekernel: i think that is to be expected to some degree16:37
wpwraklekernel: i think the people who have the most accurate picture have other things to do at the moment than to give explanations to the global press ;)16:37
rohwpwrak: no information yet. cannot reach the host atm16:39
wpwrakroh: oh, sounds suckish16:40
rohcould be hw.. dunno yet.16:40
rohits saturday. so.. i wouldn bet on it before monday16:41
wpwrakroh: :-(16:41
kristianpaulnice aprouch20:36
tuxbrain_awaykristianpaul: once upon a time I have started  an "openmoko showrom" web site that read directly on opkg repos , http://www.tuxbrain.com/en/content/om-showroom-something-show, due openmoko start dying an I have received no support I park that project but if there is enough interest I can reconvert it to Nanonote showroom, and it can show both jlime and openwrt apps...22:41
tuxbrain_awaykristianpaul: si , que?22:55
kristianpaulse me cruzo el canal. perdon :-)22:56
wpwraktuxbrain_away: isn't that a bit like yi's list of applications ?23:18
kristianpaulwpwrak: yes i think23:19
tuxbrain_awayyes, and that's why I haven't said nothing until today... the only advantage I see over the wiki , is that the source of app is the opkg repo, so you have the description and link to the ipk file on a db, you only have to add the pic and maybe add more descritpion, new apps show up to the admins of the page... but well, as you can see I have not said nothing until today , I can stay silent again on it :) , in fact I have not much motivation to re23:22
tuxbrain_awayt that project.23:22
Action: tuxbrain_away is reading about slave spi on Atmega chips...23:23
kristianpauloh.. be aware of tuxbrain_away new ideas ! ;-)23:24
tuxbrain_awayvery few information most of people trying has go to I2C23:24
kristianpaulAnd finally stops looking at uart :-)23:24
kristianpaultuxbrain_away: yeah, i2c is well known23:25
tuxbrain_awaywell we should find a way to atmega(uart->slave spi) ->nn(master SPI ->/dev/watevertty)23:26
tuxbrain_awayalso would be cool23:29
tuxbrain_away(ethernet->slave spi)->NN(master SPI->/dev/ethX)23:29
tuxbrain_awaybtw, you think UBB can be used also as I2C interface?23:29
rohsure. bitbanging.23:30
rohin gpio mode23:30
tuxbrain_awayso just as we achived the SPI master23:31
tuxbrain_awaymaking wpwrak coding it :P23:32
tuxbrain_awaywpwrak: still waiting for the files for atben/atusb23:33
tuxbrain_awayno rush just want to make you notice in case of you have try to send somthing , I have no recive anithing yet23:34
wpwraktuxbrain_away: for the smt files, i'll actually need input from adam. but maybe you don't require all the details for a quote.23:34
wpwraktuxbrain_away: no haven't sent something. hmm, with the imap.openmoko.org troubles, that could become an issue, too. well, sending ought to be fine, just not receiving any bounces or such.23:35
wpwraktuxbrain_away: (spi, i2c, ...) in fact, there are drivers for this in the kernel already ;-)23:36
wpwraktuxbrain_away: (no rush) in fact, i figured that it wouldn't be overly useful for you before monday morning, so i get one more day to slack :)23:37
kristianpaulwpwrak: (kernel) oh i2c too, nice :-)23:41
tuxbrain_awaywpwrak: (kernel) well this is like telling to me that driver are in a cave in uganda.... I will arrive there but it will take me some time23:43
wpwraktuxbrain_away: so better start the journey fast ;-)23:44
tuxbrain_awayyep the hard part is to convice my wife this is usefull for something :P23:44
tuxbrain_awayshe is still waiting for the freaks knoking at my door for the Ardunote initative23:46
Action: kristianpaul nok nok23:46
tuxbrain_awaycommon kristianpaul you are already sitting in my sofa drinking beer for a while :) I mean new and huge amount of freaks :P23:47
wpwraktuxbrain_away: (ardunote) any reactions so far ?23:48
wpwraktuxbrain_away: i'm kinda curious what else will crawl out of ubb, we's still a few things short to make it truly accessible, but then, maybe others can help there, too23:50
tuxbrain_awaywpwrak: few less than expected I must say but well ... the more encouraging and discouraging at same time is one guy of the Arduino spanish comunity telling me : "Hey well done!, when will be a GUI ready?" (sight)23:50
kristianpaulthats expected23:51
kristianpaulgui and arduino are a team23:51
tuxbrain_awaykristianpaul: yeah I know is on my roadmap , but there a tons of thing to be done before reach that point23:52
kristianpaulyou explain the avrdude part and is like saying there are programinn in asm23:52
kristianpaulmemory one if then..23:52
kristianpaulor a lot of swap...23:53
kristianpaulor write the editor with sdl and then call avrdude23:53
wpwraktuxbrain_away: (ardunote) needs a bit more pushing, i guess. also the use case may not be obvious23:56
tuxbrain_awayof course runing the actual arduino soft is totally out of scope, I have to write or adapt an already done editor and make it looks like the arduino front end and as you said call avrdude, the idea is to make the gui generate the make file and runt make and avrdude in the backstage :)23:56
wpwraktuxbrain_away: also, the use of your ardunote goes beyond just the arduino23:57
tuxbrain_awaywpwrak: well I'm working with some 3D printers guys and maybe we will have the first use case as 3d printer frontend :)23:57
tuxbrain_awaywpwrak: yeah it about all avr chips :)23:57
kristianpaulwhy not just advertise: This guy program arduino without a PC23:57
wpwraktuxbrain_away: (3d printer) wow23:58
Jay7kristianpaul: by his mind power! :)23:58
kristianpaultuxbrain_away: 3d print? wich printer?23:58
kristianpaulJay7: :)23:58
tuxbrain_awaykristianpaul: you will see, actually I'm under NDA yet23:58
kristianpaulNDA? no way thats extratasys? ;-)23:59
kristianpaulsure is a makerbot as hackable devices sell it too23:59
wpwrakJay7: well Obi-Wan Kenobi was known as Ben Kenobi. this should give us a hint :)23:59
