DocScrutinizer: better read the tail-between-the-legs statement that "you can't 'make' hardware" and then see how far we've come already
<DocScrutinizer>
who stated that?
<DocScrutinizer>
and who's "you"? ;-D
<wpwrak>
DocScrutinizer: sean had a presentation on openmoko scheduled for i think it was just after the first bloodletting. at a conference in switzerland, if i remember right. and there he made a statement in that sense. i probably got the wording wrong, though.
<DocScrutinizer>
aah, by "you" he meant OM mgmt ;-P
<DocScrutinizer>
I.E. self()
<wpwrak>
with the implied assertion of universality. it's all Kant in a way ;-)
<DocScrutinizer>
it's never been the 'making' that's the problem. Always the 'marketing' though
<wpwrak>
naw, marketing must have been easy, with all the hype surrounding openmoko. that was really incredible. wish we had half that for qi-hw.
<DocScrutinizer>
qi-hw is missing the intriguing topic of "smartphone"
<wpwrak>
oh, today it wouldn't get so much interest either
<DocScrutinizer>
well, maybe qi is ahead of time, next buzzword been "tablet"
<DocScrutinizer>
:-D
<wpwrak>
yeah. let's make nanonote and milkymist the next big thing after the tablet
<DocScrutinizer>
wearables - if I may dare a prophecy
<wpwrak>
that may not be a bad guess. we're certainly heading this way.
<DocScrutinizer>
qi should be at the exactly right location for this enterprise. Isn't all western clothing manufactured in far east? (yeah, or Bangladesh)
<wpwrak>
wherever it is, the next qi-hw representative ain't far ;-)
<DocScrutinizer>
lol
<DocScrutinizer>
Qi-HW, Berlin London, New York, Taipei, Bangalore
<wpwrak>
it gives me the chills though that i'd be the closest representative for antarctica. well, until rafa comes back
<wpwrak>
barcelona, colombia, ...
<DocScrutinizer>
seems even 'big players' only have EMEA, America, Asia
<wpwrak>
we don't seem to have much coverage in africa and au/nz either, though
<DocScrutinizer>
no coverage in Ozz? how's that?
<DocScrutinizer>
quite unusual, I'm always amazed how many users are from there
<DocScrutinizer>
curses missing regex grep on userlist of IRC client
<DocScrutinizer>
o/ roh
<wpwrak>
dunno. just haven't noticed anyone from down under
<wpwrak>
DocScrutinizer: i think kyak is now the official IRC bot enhancer :)
<DocScrutinizer>
aah, you think like
<DocScrutinizer>
qi-bot: seen *au*
<wpwrak>
has a nice ring to it, no ?
<DocScrutinizer>
hihi cttv tests RL-twitter, with megaphone down in the streets. Strange, it doesn't work
<wpwrak>
anyway, time for me to crash for a bit. had a busy day.
<DocScrutinizer>
enjoy
<DocScrutinizer>
time for 12648430Â Â
<DocScrutinizer>
here
<DocScrutinizer>
(I'd love to design a few wearables together with qi-hw :-D )
<DocScrutinizer>
meh, qi-bot is quite uncommunicative
<kyak>
:)
<LunaVorax_mini>
erp ?
<DocScrutinizer>
kyak: nice :-D
<DocScrutinizer>
kyak: the plan however was to find australian users in this chan. Seems it's not exactly simple to establish that using the !seen *xy* cmd
<DocScrutinizer>
kyak: of course I tried "help" (plus a few others) in a /query qi-bot, which resulted in [2011-03-27 08:46:16] <DocScrutinizer> meh, qi-bot is quite uncommunicative
<DocScrutinizer>
[So 27. März 2011] |[08:45:15] <DocScrutinizer>| help
<DocScrutinizer>
[2011-03-27 10:33:53] <qi-bot> ... All commands can sent to me in pm without "!" prefix.--
<DocScrutinizer>
I.E. this isn't exactly true, 'help' doesn't work this way
<tuxbrain>
DocScrutinizer:Â Â (wearables) Yes!, also very in line with Arduino next move :), David Cuartielles one of his founders, has also near to publish a book about it :) , so some atmegas arround jacket and trousers and a brain/hmi based on qi-hw is not really a bat a idea at all
<DocScrutinizer>
tuxbrain: :-D
<DocScrutinizer>
I'm more interested in the 'embeeded' (enweaved) things though, not the hmi/mmi
<DocScrutinizer>
ideally there's no such thing like a dedicated device for mmi. Just a 'service terminal' you hook up at home, to configure things
<tuxbrain>
DocScrutinizer: and why not configure it directly on the ankward of you foreaarm with a wearable screen that make you able to do so on the go , and with an 6lowpan that make you able to even configure it with your desktop computer without need to plug anything? :)
<tuxbrain>
or even better a cute light glasses to view and reserve the forearm for control/typing :)
<DocScrutinizer>
tuxbrain: yeah, of course.
<DocScrutinizer>
reminds me to file a few patents for my special glasses
<DocScrutinizer>
damn, that's where hw-development starts to get annoyingly expensive and unfeasible for a mere mortal
<DocScrutinizer>
special build of LCDs etc
<DocScrutinizer>
possibly even non-standard LC itself (not that you'd be able to get such thing like "standard" LC in small quantities)
<DocScrutinizer>
not to mention the glass electrodes coated with transparent conductive material
<DocScrutinizer>
spacers, whatnot
<kyak>
DocScrutinizer: --^ :)
<DocScrutinizer>
nice
<DocScrutinizer>
scribbles on a virtual postit note "install eggdrop" and sticks that note to some part of his neocortex
<tuxbrain>
DocScrutinizer: please translate all above tech mambo jambo to an aprox amount.
<tuxbrain>
and if you have a abstract of that idea please let me take an eye.
<DocScrutinizer>
the simple bottom line: you actually can not build your own LCD
<DocScrutinizer>
(as you'd need e.g. for a shutter glasses' glasses, or would you like to use goggles with two pcs 2.4" LCDs as glasses?)
<tuxbrain>
Doc I'm a little bit lose on the vocabulary shutter? googgles? any let me search to see what you mean
<DocScrutinizer>
yeah, and the point is you can't built the needed shutter LCDs yourself. I'd have some rather smart (IMHO) ideas regarding combining shutter function, HMD (actual content mirrored in to the glasses via micro projector), and some ultra-geeky sunglasses function like selective dimming.
<DocScrutinizer>
~dict goggles
<DocScrutinizer>
oops, no ibot here
<DocScrutinizer>
!dict goggles
<DocScrutinizer>
thought as much
<DocScrutinizer>
tuxbrain: yeah, the last one is what my idea is based on
<DocScrutinizer>
e.g. camera can detect direction of sun and selectively dim out that area in the goggle's shutter glasses
<DocScrutinizer>
you can have true alpha channel in content mirrored into your view
<DocScrutinizer>
get the picture?
<tuxbrain>
I agree to , we can found a way that it can be addapted to existent glasses too? maybe without some ot the fancy fucntions like auto dark glass, just show me info device?
<DocScrutinizer>
hard to find good links, even harder to find vivid sites actually selling
<DocScrutinizer>
>>wearable computing: Wearable computing hopes to shatter this myth of how a computer should be used. A person's computer should be worn, much as eyeglasses or clothing are worn, and interact with the user based on the context of the situation. With heads-up displays, unobtrusive input devices, personal wireless local area networks, and a host of other context sensing and communication tools, the wearable computer can act as an
<DocScrutinizer>
intelligent assistant, whether it be through a Remembrance Agent, augmented reality, or intellectual collectives. (from the MIT Wearable Computing WWW page)<<Â Â hardly anything to add - from http://www.hitl.washington.edu/scivw/visual-faq.html
<GNUtoo|bug20>
does the arduino lilipad count in wearable computing?
<wpwrak>
DocScrutinizer: (lissajous) nice ! finally a good use for xy mode :)
<wpwrak>
kristianpaul: if you can just count cycles, you can synchronize with ntp. ntp has very little drift but there's a possibly large random-ish offset when you take the sample. a few ppm for a measurement period of ~1h should be feasible, though.
<DocScrutinizer>
wpwrak: yeah, but still you need a reference that's not too far off from what you try to calibrate
<wpwrak>
DocScrutinizer: only if you're in a hurry :)
<DocScrutinizer>
e.g. here in EU we got dcf77 which is a 77.5(?)kHz RF frequency and time normal
<wpwrak>
yeah, dcf77 is nice
<DocScrutinizer>
you can't get useful lissajous with that, for e.g 16Mhz
<wpwrak>
ah, sure. i wasn't talking about lissajous. i was thinking of counting cycles over one ntp hour, then see how many you got, and tune accordingly. repeat until you either have it right or until you declare defeat in before overwhelming temperature drift :)
<DocScrutinizer>
:-D
<rm>
I wish nanonote would have built-in wifi :/
<wpwrak>
wpan ! wpan ! wpan ! :)
<DocScrutinizer>
gigs thru his boxes in attic to find the WPAN AP
<steve|m>
who said jehova? ;)
<kristianpaul>
rm, wpwrak already develop an copyleft alternative to clasic wifi (wpan)
<wpwrak>
DocScrutinizer: you have to look in those labeled "future"
<DocScrutinizer>
what's the name of those pills?
<rm>
or bluetooth (but bluetooth is ewwww)
<rm>
and also highly proprietary, no
<rm>
point is, if it had wireless communication out of the box, it'd be an order of magnitude more attractive/useful
<kristianpaul>
btw this coming wpan linux support hopefully will allo to hookup a wpan to my linksys router isnt? same as with the RFM12B module
<steve|m>
wpwrak: heh, it's already in the wireshark OUI-database as well :)
<kristianpaul>
haha
<wpwrak>
kristianpaul: does your linksys have usb host ?
<wpwrak>
kristianpaul: or at least spi / gpios for bit-banging ?
<kristianpaul>
i WILL *not* use USB :-D
<kristianpaul>
wpwrak: yes spi :-)
<wpwrak>
who "*not*" usb ?
<wpwrak>
s/who/why/
<kristianpaul>
I consider un necesary
<kristianpaul>
for the troughput you may get
<wpwrak>
(spi) then you'll be able to hack an atben to do your bidding :) well, you'll also need a few more gpios for control signals. reset (semi-optional), standby (optional), interrupt
<kristianpaul>
hmm
<wpwrak>
the advantage of usb would be that you could just plug in an atusb :)
<kristianpaul>
thast true
<wpwrak>
(and increase tuxbrain sales in the process :)
<kristianpaul>
oh sure :-)
<rm>
what games would you suggest
<rm>
to try on "simple" devices like nanonote (and for me right now on yeeloong)
<kristianpaul>
jlime muffinman ships nice games
<kristianpaul>
there is also a #jlime channel in wich you can get better recomendations about games ;-)
<kristianpaul>
dingux also use same Xbusrt SoC as nanonote and is a game console oriented device
<wpwrak>
DocScrutinizer: one question is a bit more basic: what do the Q/I components really signify ?
<wpwrak>
DocScrutinizer: it's more clear in the FFT. but in the time domain, what does the imaginary part really mean ?
<DocScrutinizer>
wpwrak: where?
<DocScrutinizer>
usually iirc the I component is the 90° shifted part so basically the phase
<wpwrak>
DocScrutinizer: (where) for example in the chip kristianpaul uses. there, he gets Q and I
<wpwrak>
DocScrutinizer: and i have the same in the USRP. so i'm kinda curious what this really means, too :)
<DocScrutinizer>
sorry, I can't follow. is that a signal, or what?
<wpwrak>
DocScrutinizer: (phase) yes, i understand that for the frequency domain. but what does it mean in the time domain ? how does even the concept of a phase enter in individual samples ?
<DocScrutinizer>
NFC
<wpwrak>
DocScrutinizer: my DSP book explains the complex time domain also more or less in terms of the frequency domain, so this doesn't really help
<DocScrutinizer>
sorry, I never seen any I and/or Q on e.g. an AD converter
<kristianpaul>
I/Q is part of a downconvertion
<DocScrutinizer>
so I can't comment on whatever you're asking me
