| z0d | hi | 06:40 |
|---|---|---|
| kyak | hey | 06:41 |
| wpwrak | rejon: good morning :) when are you heading out ? | 11:46 |
| kyak | wpwrak: may i ask you a fast question: how can i choose which one of 16 channels in 2.4Ghz band will be used by atben/atusb? And does it make sense to choose a channel different from the oen used by my 2.5 Ghz router nearby? | 11:54 |
| kyak | *2.4 Ghz | 11:55 |
| kyak | i.e. will i gain soemthing from this? | 11:55 |
| wpwrak | yes, it's better to be far away from frequencies with interferences | 12:01 |
| wpwrak | in atrf-*, you specify the channel with -c # | 12:01 |
| wpwrak | in iz... you change the places where it says "11" | 12:02 |
| kyak | my router is just 1 meter away from laptop :) so ok, i'll be changing the channel | 12:02 |
| wpwrak | note that wlan and wpan use different channel numberings | 12:02 |
| kyak | it's using channel 6 now btw | 12:02 |
| wpwrak | atrf-rssi -g ca show you the map;ping | 12:02 |
| kyak | ok, thanks | 12:03 |
| wpwrak | press E and it'll show the channel numbers at trhe bottom, inclusing the typical EU assignment | 12:03 |
| wpwrak | U for US, J for japan | 12:03 |
| kyak | i'll try that, thnkas | 12:03 |
| qi-bot | [commit] Stefan Schmidt: spi/atusb: Static info request during probe is async for usb now. (ben-wpan-stefan) http://qi-hw.com/p/qi-kernel/1414ef5 | 16:13 |
| rjeffries | these guys are interesting. open license just like qi-hardware. http://leaflabs.com/devices/ | 16:13 |
| rjeffries | MIT license for hardware is A Good Thing, correct? | 16:41 |
| rjeffries | They use KiCad. This is an interesting interview. http://dangerousprototypes.com/files/DP-LeafLabs-Maple.mp3 | 16:44 |
| kristianpaul | MIT, humm | 16:44 |
| kristianpaul | is it copyleft? | 16:44 |
| kristianpaul | remener not all open source and free software licenses are copyleft | 16:44 |
| kristianpaul | remenber* | 16:44 |
| rjeffries | their current license is actually share alike, they plan to go to MIT as it is MORE permissive | 16:45 |
| kristianpaul | see ! | 16:45 |
| kristianpaul | not all people like copyleft,but thats a separate topic :) | 16:45 |
| rjeffries | these guys closley resemble the qi-hardware crew check them out | 16:45 |
| kristianpaul | old club way | 16:45 |
| kristianpaul | closelly? | 16:45 |
| rjeffries | well, they are not spread all over the world yet | 16:46 |
| rjeffries | they switched to KiCad from Eagle because KiCad is open, ;) | 16:46 |
| kristianpaul | they document how maufacture stuff? | 16:47 |
| kristianpaul | actually do they manufacture or just sell prototypes? | 16:47 |
| rjeffries | They manufacture. Doing some good work. | 16:48 |
| kristianpaul | nice | 16:48 |
| kristianpaul | how easy is to reproduce that good work? | 16:49 |
| rjeffries | if you listen to the interview, it is really interesting | 16:49 |
| rjeffries | go look at their site. they share oretty well I think) | 16:49 |
| kristianpaul | no time know, but i prefer read :) | 16:49 |
| kristianpaul | bbl | 16:49 |
| rjeffries | they mention OpenMoko (they borrowed DFU from it) | 16:51 |
| wpwrak | talk done :) now it's the drinking phase of the conference ;-) | 17:46 |
| kristianpaul | hey | 17:47 |
| kristianpaul | how was it? | 17:47 |
| kristianpaul | interesting questions? | 17:47 |
| kristianpaul | trolls? | 17:47 |
| kristianpaul | Talk is it recorded somwhere? | 17:47 |
| wpwrak | only had time for two. one was about what we learned from openmoko ;-) | 17:48 |
| kristianpaul | nice questions :) | 17:48 |
| wpwrak | dunnp. could be. i'll need to ask around | 17:48 |
| kristianpaul | worth the try | 17:48 |
| kristianpaul | so wen can link it to next news | 17:48 |
| kristianpaul | s/wen/we | 17:48 |
| wpwrak | the other question was about the open-source hw license | 17:49 |
| kristianpaul | you ran the slides from the nanonote btw? | 17:49 |
| wpwrak | naw, didn't have time to set this up | 17:49 |
| kristianpaul | open-source, like MIT Apache and BSD ? :) | 17:49 |
| kristianpaul | anyway, enjoy your drinks | 17:50 |
| Action: kristianpaul lunch time | 17:50 | |
| wpwrak | (license) we talked about it some time here. but it wasn't too good. | 17:50 |
| wpwrak | rejon: 5 min to go :) | 17:52 |
| rejon | :) | 17:52 |
| wpwrak | rejon: i'll be iin the spwaker's lounge later | 17:52 |
| kristianpaul | milkymsit one? | 17:55 |
| kristianpaul | rejon:'s talk i mean | 17:55 |
| wpwrak | new, some edu thing | 17:55 |
| wpwrak | yes | 17:55 |
| wpwrak | M1 is on saturday | 17:55 |
| kristianpaul | hum, like the sugar platform or something? | 17:56 |
| kristianpaul | ok | 17:56 |
| wpwrak | (edu) new, non-technical i think | 17:56 |
| kristianpaul | great | 17:56 |
| wpwrak | relocating :) | 18:02 |
| qi-bot | [commit] Werner Almesberger: tools/Makefile (BEN_DIRS): comment out dirtpan again, to avoid hdr dependency (master) http://qi-hw.com/p/ben-wpan/673d29a | 19:02 |
| qi-bot | [commit] Werner Almesberger: TODO: various updates (master) http://qi-hw.com/p/ben-wpan/d94ac95 | 19:02 |
| wpwrak | kristianpaul: the streaming should be here: http://tv.softwarelivre.org/ | 19:06 |
| wpwrak | kristianpaul: will take a while for mine to show up. they first have to censor the clips ;-) | 19:07 |
| kristianpaul | thanks for the link | 19:09 |
| kristianpaul | changing topic | 19:09 |
| kristianpaul | i think was wrong asume 0 and -0 as a valida value coming from the sige ADC | 19:09 |
| kristianpaul | -3, -1, 1 , 3 looks more sensate | 19:09 |
| kristianpaul | i said that after ecounter some division by zero warnigns in a octave i was trying with the sampled data | 19:10 |
| wpwrak | ;-) | 19:11 |
| kristianpaul | now it seems the missing part is a mixer for the complex values | 19:11 |
| kristianpaul | for osgps | 19:11 |
| wpwrak | that's what you'll find in the math textbooks ? :) | 19:11 |
| kristianpaul | yes,but i tought it was arelady implemented | 19:12 |
| kristianpaul | if a software said that can analize in-phase nand quadrature samples, i asumed it was implented | 19:12 |
| kristianpaul | i still having my doubts and still reviwing osgps source code | 19:13 |
| qi-bot | The build was successfull, see images here: http://fidelio.qi-hardware.com/~xiangfu/compile-log/openwrt-xburst.full_system-06292011-1525/ | 19:14 |
| kristianpaul | in the other hand i noticed that sige evb manual have some isntructions to put sige chip in real mode | 19:20 |
| wpwrak | oh. that sounds interesting | 19:20 |
| kristianpaul | well, acording to books and speedevil comments, this will mean 4x data compared to I/Q sampling | 19:21 |
| kristianpaul | but indeed, most of the code i had found asume real data | 19:21 |
| kristianpaul | what sige adds is their propietary downcoverter serializer for making esier the later processing | 19:21 |
| kristianpaul | and it is truth in theory cause if implemente the correlator in hardware, ie namuru, i may not need to use some correlation arms, asuming i trust sige for what is I and Q | 19:22 |
| kristianpaul | yeah, i'll try check the output for real putput with scope tonight :) | 19:23 |
| kristianpaul | now IF sampling willbe ~16Mhz instead of 2.556Mhz from the downcoverter | 19:24 |
| kristianpaul | actually sige chip will be kinda same as the maxim one too | 19:24 |
| kristianpaul | but we'll se :) | 19:24 |
| kristianpaul | see* | 19:24 |
| kristianpaul | wpwrak: complex is the data type implemed in C99 for complex number inst? | 19:25 |
| wpwrak | (like maxim) then you'll even have a second soure :) | 19:25 |
| wpwrak | sourCe | 19:26 |
| kristianpaul | cause at first grep it dint showed up from osgps.. | 19:26 |
| kristianpaul | or this graph lied to me http://home.earthlink.net/~cwkelley/receiv5.gif :p | 19:26 |
| wpwrak | maybe they do complex math with real/int math | 19:26 |
| kristianpaul | good point | 19:28 |
| kristianpaul | wpwrak: yeah, not only a second source in hardware, also more code to analize the data, inclduing the SoftGNSS port to octave (thanks a lot david his fix to it), fastgps too | 19:33 |
| kristianpaul | and gps-sdr from CTAE | 19:33 |
| kristianpaul | okay, i'll change that resistor position and see how the data came out from it :) | 19:33 |
| wpwrak | resistor position ? | 19:36 |
| DocScrutinizer | 0R | 19:37 |
| DocScrutinizer | ? | 19:37 |
| kristianpaul | in the EVB hw1 and hw0 defines the chip mode | 19:37 |
| wpwrak | ah :) | 19:37 |
| kristianpaul | 47K actually DocScrutinizer | 19:37 |
| kristianpaul | because it need to be set low | 19:38 |
| DocScrutinizer | thought as much, but 0R been to the point ;-) | 19:38 |
| kristianpaul | http://read.pudn.com/downloads166/ebook/765861/SE4150L_Datasheet_Rev_1p0.pdf | 19:44 |
| kristianpaul | make sense, the one i have is SE4162, so this was before :) | 19:44 |
| wpwrak | rejon: so ... when do you want me to break your M1 ? :) | 19:46 |
| rejon | yeah | 20:01 |
| wpwrak | when ? today ? tomorrow ? saturday befoe your talk / sat after your talk ? | 20:02 |
| wpwrak | or some undefined future ? :) | 20:02 |
| rejon | do we have time now? | 20:02 |
| wpwrak | i guess we can try our luck and still make the 6pm shuttle | 20:04 |
| wpwrak | or else another day :) | 20:05 |
| rejon | wpwrak, sorry, getting distracted | 20:13 |
| rejon | with fab stuff | 20:13 |
| wpwrak | heh :) | 20:14 |
| wpwrak | sounds like a "tomorrow" vote then | 20:15 |
| wpwrak | and what exactly are you guys fabbricating ? :) | 20:19 |
| kristianpaul | electric motorcycles? | 20:26 |
| kristianpaul | :) | 20:26 |
| methril_work | rejon, are you fabbricating something in Brazil? | 20:33 |
| rejon | not yet | 20:34 |
| rejon | would like to! | 20:34 |
| viric | rejon: like what? | 20:34 |
| methril_work | rejon, i would like to help on this matter | 20:35 |
| methril_work | ?) | 20:35 |
| methril_work | :) | 20:35 |
| viric | quem e brasileiro aqui? | 20:35 |
| methril_work | ninguem, mais estou morando no Brasil :) | 20:36 |
| viric | na cidade? | 20:37 |
| methril_work | Pelotas - RS | 20:37 |
| viric | ah. nao conheço. rejon tambem? | 20:38 |
| viric | also rejon ? | 20:39 |
| methril_work | viric, are you in Brazil? I though you where from Barelona (Spain) | 20:39 |
| viric | methril_work: no, from Girona, Catalunya :) | 20:40 |
| viric | methril_work: we work with some people in Brasil related to some closed electronics :) | 20:40 |
| methril_work | we met at Fix Party bcn | 20:40 |
| methril_work | viric, really? | 20:40 |
| viric | methril_work: with me? I doubt it | 20:40 |
| viric | What is that party? :) | 20:40 |
| viric | I never heard of it | 20:41 |
| methril_work | you are not a Fixed OpenMoko owner? | 20:41 |
| viric | no no | 20:41 |
| methril_work | then i`m wrong :) | 20:41 |
| methril_work | i`m the party fixer in Spain | 20:41 |
| methril_work | but i rellocate last year | 20:41 |
| viric | You got close though. | 20:42 |
| rejon | i'm here with wpwrak at FISL | 20:42 |
| viric | ahh | 20:42 |
| rejon | yes, great to make qi hardware here | 20:42 |
| rejon | nanonotes, mm1, etc :) | 20:42 |
| viric | Congratulations :) | 20:43 |
| kristianpaul | if you manage to bypasss customs and import laws i guess | 20:43 |
| rejon | why? | 20:43 |
| rejon | just make them here | 20:43 |
| methril_work | kristianpaul, you have tax reductions if you are a producer | 20:43 |
| rejon | not sure about raw materials | 20:43 |
| rejon | anyway, this is all speculative optimism :) | 20:43 |
| kristianpaul | yeah, tha was my point | 20:43 |
| kristianpaul | methril_work: are you a producer? you just said some minutos about some magic words about electronics :) | 20:44 |
| kristianpaul | s/abot/ago | 20:44 |
| methril_work | kristianpaul, unfortunately i`m not a producer | 20:45 |
| methril_work | i`m only a electronic user | 20:45 |
| methril_work | but.... i`m brazil located so i`m interested in any qi initiative here | 20:45 |
| kristianpaul | btw is ANATEL familiar with with you? | 20:45 |
| methril_work | i know what ANATEL is | 20:46 |
| kristianpaul | s/familiar/aware | 20:46 |
| methril_work | i`m not EE, so i don`t need to be aware of | 20:48 |
| methril_work | i`m in the middle of EE & SW | 20:48 |
| kristianpaul | ignore me for a while i think been in a fan less place make write more than i wich | 20:49 |
| kristianpaul | bbl i need water or somwthing, got some headched :S | 20:49 |
| rejon | sorry guys, really not paying attn | 20:52 |
