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

packet radio well thats somethin was very popular before the intertnet massive adoption

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 :)

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).

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
