<wpwrak> boring 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_Myw
<wpwrak> hellekin: 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 ?
<roh> wpwrak: not unusual (sourcing by the placer for standard components)
<roh> then they are faster doing that design.. they know their supplier and the tolerances of the reels/components already

<hellekin> we need that SDR free hardware, before it's too late http://www.edri.org/UN-threat-for-Internet
<wpwrak> nice name ;-) "Office on Drugs and Crime"
<hellekin> heh

<kristianpaul> wpwrak: nice video, now i know what to do with those old nac geo magazines... :)
<hellekin> kristianpaul: I want free spectrum, not a license. Bleh. :]
<kristianpaul> sure but we also need to agree some things
<wpwrak> hellekin: 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.
<wpwrak> you'll also need vast amounts of money, of course, but i suppose you have that stowed away somewhere :)

<rjeffries> wolfspraul 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.
<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.
<rjeffries> wpwrak I was referring to per node. the 100nW is very competive, as you know
<rjeffries> the 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.
<rjeffries> wolfspraul 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).

<kyak> xiangfu: hi, just letting you know that the problem with usbboot programming is no more as of 3.6.4
<kyak> i like it how problems suddenly appear in linux kernel and then suddenly dissappear in a next release
<kyak> xiangfu: 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 distro
<kyak> if it wouldn't require some kernel patches and stock kernel recompilations, that would've been perfect
<xiangfu> kyak, great. I don't have time re-produce hte usbboot problem on 3.6.3. now it already fixed. :)
<kyak> since the idea is to be able to run dkms on it, and that's all
<xiangfu> for atusb. it depends on modules: at86rf230, ieee802154 and mac802154.
<xiangfu> which at86rf230 and mac802154 are not in kernel so far.
<xiangfu> but there are some head files changed for atusb under ieee802154.
<kyak> i have CONFIG_MAC802154=m in my stock kernel
<kyak> CONFIG_IEEE802154=m is there as well
<kyak> at86rf230 is missing
<kyak> i think i can provide an update ieee802154 module with the change in header file you mention
<kyak> so it means i'll need to package atusb, at86rf230 and an updated ieee802154
<kyak> the rest is in the stock kernel.. right?
<xiangfu> yes.
<xiangfu> oh. the mac802154 already in 3.6 kernel.
<xiangfu> and I saw at86rf230 also included in 3.6 kernel.
<kyak> hmhm.. wonder why at86rf230 is not in in 3.6.4 i'm currently running
<kyak> not even is "is not set"
<xiangfu> kyak, http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=7b8e19b67c1b171a04f6bd2f973d0b38cb496bf6
<xiangfu> [drivers/ieee802154: add support for the at86rf230/231 transceivers]
<xiangfu> kyak, I have a git clone and applied 3.6.3 patch on it.
<kyak> oh, so at86rf230 is supported by ieee802154 driver?
<xiangfu> yes.
<xiangfu> I guess we need update atusb.c for that.
<kyak> do we still need to make that header file change you metnioned?
<xiangfu> we need find out that. :-)
<kyak> ok, overall it's not so bad.. probably we can get along with just atusb
<kyak> since the rest is in the kernel
<xiangfu> yes.
<kyak> atusb.c is not in jz-3.6 branch
<kyak> do you know where is it and what is the latest version?
jekhor has joined #qi-hardware
<xiangfu> kyak, under openwrt-xburst/target/linux/xburst/patch-3.3
<xiangfu> kyak, I also just quick copy the atusb.c to drivers/ieee802154/spi_atusb.c. and trigger the 'make' on my 3.6.4 kernel.
<kyak> heh, let's hope for the magic, right ? :)
<xiangfu> let's wait the big ERROR:... :)
<kyak> oh, judging by the number of files for linux-3.3, packaging atusb for the stock kernel would've been pain the ass
<kyak> it's good many things went upstream
<xiangfu> yes.

<xiangfu> kyak: Hi
<xiangfu> just back.
<xiangfu> kyak: I quick test atusb code. (copy spi_atusb.c to linux 3.6) then compile as kernel module. it can success resigter atusb driver.
<xiangfu> but have probelm on 'iz add wpan-phy0'. I guess we still need add some define/varialbes to some ieee802154/mac802154 head files.
<kyak> hmm
<kyak> i'll give it a try a little bit later
<kyak> but that's really good news
