#qi-hardware IRC log for Friday, 2012-11-02

wpwrakboring day at the office ? why not collect a few keyboards, mice, and some miscellanea and make a little movie ? http://www.youtube.com/watch?v=m4YPDh8_Myw00:01
wpwrakhellekin: as ballpark numbers, the prices you have there don't look too unreasonable. it's a bit strange to lump pick and place and parts into one item, though. i guess that's an smt fab that also does (partial) sourcing for its customers ?00:14
rohwpwrak: not unusual (sourcing by the placer for standard components)00:22
rohthen they are faster doing that design.. they know their supplier and the tolerances of the reels/components already00:22
qi-bot[commit] Werner Almesberger: ircstat/stat: new option -a to also plot the last (partial) month (master) http://qi-hw.com/p/wernermisc/72db39300:24
qi-bot[commit] Werner Almesberger: ircstat/ML: update for 10/2012 (master) http://qi-hw.com/p/wernermisc/f87f0e600:24
hellekinwe need that SDR free hardware, before it's too late http://www.edri.org/UN-threat-for-Internet00:43
wpwraknice name ;-) "Office on Drugs and Crime"00:45

kristianpaulhellekin: get a ham license01:39
kristianpaulpacket radio well thats somethin was very popular before the intertnet massive adoption01:40
kristianpaulwpwrak: nice video, now i know what to do with those old nac geo magazines... :)01:53
hellekinkristianpaul: I want free spectrum, not a license. Bleh. :]02:03
kristianpaulsure but we also need to agree some things02:12
wpwrakhellekin: your problem isn't technology but law. you need to find the loopholes that let you implement your global anti-establishment network, then pick the corresponding technology. oh, and keep the politicians well-pampered so that they don't close those loopholes while your're building your network.02:19
wpwrakyou'll also need vast amounts of money, of course, but i suppose you have that stowed away somewhere :)02:20
rjeffrieswolfspraul the chips from http://www.greenarraychips.com/ are real. They are not open design, it is a for-profit company.Impressive as example of extremely low energy chips. 03:38
wpwrak"extremely low energy" ? not really. it's 100 nW per "computer" and you have 144 of them, so it's 14.4 uW in total. there are quite a number of MCUs that draw less when operating at full speed.03:41
rjeffrieswpwrak I was referring to per node. the 100nW is very competive, as you know03:43
rjeffriesthe architecture of the Greenarray multi-core chip is (to me) interesting. I suspect they have a couple of 3-letter agencies that use the parallel chips in some obscure way.03:45
rjeffrieswolfspraul I seriously doubt there is anything about Greenarrays that will be of interest. the ISA is FORTH. Interesting, but sufficiently off the beaten path to be a "don't care" for whatever it is you are doing (which I do not yet grok). 03:47
kyakxiangfu: hi, just letting you know that the problem with usbboot programming is no more as of 3.6.405:02
kyaki like it how problems suddenly appear in linux kernel and then suddenly dissappear in a next release05:03
kyakxiangfu: could you give any hints about how to integrate atusb in linux-3.6 as a kernel module? I'd like to package it for my distro05:05
kyakif it wouldn't require some kernel patches and stock kernel recompilations, that would've been perfect05:05
xiangfukyak, great. I don't have time re-produce hte usbboot problem on 3.6.3. now it already fixed. :)05:06
kyaksince the idea is to be able to run dkms on it, and that's all05:06
xiangfufor atusb. it depends on modules: at86rf230, ieee802154 and mac802154. 05:14
xiangfuwhich at86rf230 and mac802154 are not in kernel so far. 05:15
xiangfubut there are some head files changed for atusb under ieee802154.05:15
kyaki have CONFIG_MAC802154=m in my stock kernel05:16
kyakCONFIG_IEEE802154=m is there as well05:16
kyakat86rf230 is missing05:17
kyaki think i can provide an update ieee802154 module with the change in header file you mention05:18
kyakso it means i'll need to package atusb, at86rf230 and an updated ieee80215405:18
kyakthe rest is in the stock kernel.. right?05:18
xiangfuyes.05:20
xiangfuoh. the mac802154 already in 3.6 kernel.05:20
xiangfuand I saw at86rf230 also included in 3.6 kernel.05:20
kyakhmhm.. wonder why at86rf230 is not in in 3.6.4 i'm currently running05:22
kyaknot even is "is not set"05:22
xiangfukyak, http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=7b8e19b67c1b171a04f6bd2f973d0b38cb496bf605:25
xiangfu[drivers/ieee802154: add support for the at86rf230/231 transceivers]05:26
xiangfukyak, I have a git clone and applied 3.6.3 patch on it.05:27
kyakoh, so at86rf230 is supported by ieee802154 driver?05:28
xiangfuyes. 05:28
xiangfuI guess we need update atusb.c for that. 05:29
kyakdo we still need to make that header file change you metnioned?05:29
xiangfuwe need find out that. :-)05:29
kyakok, overall it's not so bad.. probably we can get along with just atusb05:30
kyaksince the rest is in the kernel05:30
xiangfuyes. 05:30
kyakatusb.c is not in jz-3.6 branch05:32
kyakdo you know where is it and what is the latest version?05:32
xiangfukyak, under openwrt-xburst/target/linux/xburst/patch-3.305:38
xiangfukyak, http://projects.qi-hardware.com/index.php/p/openwrt-xburst/source/tree/master/target/linux/xburst/patches-3.3/800-WPAN-new-files.patch05:39
xiangfukyak, I also just quick copy the atusb.c to drivers/ieee802154/spi_atusb.c. and trigger the 'make' on my 3.6.4 kernel.05:40
kyakheh, let's hope for the magic, right ? :)05:41
xiangfulet's wait the big ERROR:... :)05:41
kyakoh, judging by the number of files for linux-3.3, packaging atusb for the stock kernel would've been pain the ass05:42
kyakit's good many things went upstream05:43
xiangfuyes.05:45
xiangfukyak: Hi07:42
xiangfujust back.07:42
xiangfukyak: I quick test atusb code. (copy spi_atusb.c to linux 3.6) then compile as kernel module. it can success resigter atusb driver. 07:43
xiangfubut have probelm on 'iz add wpan-phy0'. I guess we still need add some define/varialbes to some ieee802154/mac802154 head files. 07:43
kyakhmm07:59
kyaki'll give it a try a little bit later08:00
kyakbut that's really good news08:00
