<kristianpaul>
ha, crazy idea a portable wikinews reader and editor
<wolfspraul>
a good idea, but people solve 'everything' with their Android or iOS device nowadays, no?
<kristianpaul>
yeah, unless they realize those devices track then...but who care enought about that today.. at  least wich journalist
<kristianpaul>
may be add tor, that asumes it chips a gsm modem, may be with sim tracer to try to be more "secure"..
<kristianpaul>
he
<kristianpaul>
i need sleep better
<kristianpaul>
bet online devices is defiant :)
<wolfspraul>
I was thinking about speakers lately
<wolfspraul>
thanks to Jon and Laoban...
<kristianpaul>
oh, good, i tought idea was removed from qi-wiki because not time for it yet...
<wolfspraul>
removed? no
<kristianpaul>
but i saw it, nice speakrs a bit big
<wolfspraul>
it's an analog only system
<wolfspraul>
interesting
<kristianpaul>
yes it was somwhere in the main page
<kristianpaul>
lot of people love analog
<kristianpaul>
i will pay to save my data on a LP ;-)
<wolfspraul>
hmm
<kristianpaul>
well not alll data
<kristianpaul>
gpgkey or something..
<kristianpaul>
hehe
<wolfspraul>
I was thinking whether m1 (or the ben) can be used in conjunction with speakers somehow
<wolfspraul>
m1 could definitely control a whole bunch of audio outputs in parallel
<wolfspraul>
then you still need an amplifier
<wolfspraul>
and a lot of software to make it real instead of just an idea
<wolfspraul>
but I don't know exactly what the Wolfson DAC can do, or what the fpga can do to drive an analog signal (are there built-in dacs? no idea...)
<wolfspraul>
anyway just thinking
<kristianpaul>
sure :)
<wolfspraul>
maybe there is something interesting in speakers
<wolfspraul>
kristianpaul: you tell me. can m1 control/drive analog audio outputs?
<kristianpaul>
i dont see why not
<wolfspraul>
right now we have the Wolfson codec, my understanding is that it converts from ac97 to line-out
<wolfspraul>
but we are limited by the capabilities of that codec I would think. so only 1 line-out?
<wolfspraul>
can there be 10?
<kristianpaul>
ah, good point :)
<kristianpaul>
let me check
<kristianpaul>
i just can see a what seems second analog output
<wpwrak>
(speakers) seems a bit far from what we're doing. shipping would probably be prohibitively expensive, so you'd need to work with retail networks. sounds like a lot of work.
<wolfspraul>
that's what I thought at the beginning
<wolfspraul>
Jon had a hard time with me :-)
<wolfspraul>
I thought:
<wolfspraul>
a) no software
<wolfspraul>
b) 'just' a speaker = no innovation
<wolfspraul>
but over the last months I realized there may be more there, somewhere. maybe.
<wolfspraul>
a speaker is an interface to the analog world, the real world
<wpwrak>
so are many other things, too :)
<wolfspraul>
yes sure, I'm just thinking
<wpwrak>
kristianpaul: we have to watch what gurus wolfgang frequents :)
<wolfspraul>
like you could have a hoarde of Nanos, connected over wired or wireless networking, each driving one analog speaker input
<wolfspraul>
even if just for fun, a hacking project
<wolfspraul>
speakers are culture, people love them, build them, use them. so there's value there (potential customers). not everybody turns to a digital snob browing the Internet the whole day :-)
<wolfspraul>
one thing I started to realize is that there's people who are strong in the analog domain
<wolfspraul>
say speakers, amplifiers, compressors, etc.
<wolfspraul>
and then there's "digital audio"
<wolfspraul>
and of course the first thing the digital audio companies are doing is to lock everybody else out
<wolfspraul>
create a black box
<wolfspraul>
they are doing all their real-time audio magic, and everybody else can just press buttons
<wpwrak>
for digital audio, you don't need to build your own speakers
<wolfspraul>
what do you mean?
<wpwrak>
you build your audio device and then connect to some existing speaker solution, with whatever interface they use
<rjeffries>
reads, smlies
<rjeffries>
s/smlies/smiles ;)
<wpwrak>
diy speakers sounds a bit like steam locomotives to me. sure, it's an art in its own right and some people are very enthusiastic about them, but ...
<wolfspraul>
ah no
<wolfspraul>
I think we can safely say that even a mid-level speaker company has more revenues than all 'open hardware' projects together
<wolfspraul>
I tried to understand how these people think, what they value
<wolfspraul>
maybe you think of a speaker only as the device that copies a digital music file into your brain
<wolfspraul>
that's how I thought about them before, but Jon didn't stop pushing me into the speaker world...
<wolfspraul>
on Friday I am ready for my first real job in helping transport a large speaker system to an evening event :-)
<wolfspraul>
Jon said I have to understand the real deal, including transporting them. I give it a try :-)
<wolfspraul>
I'm not sold yet on speakers, just thinking whether our work (nano, m1) is in any way related, or can help those guys
<wolfspraul>
logistically, of course I can make speakers and move them through my HK warehouse
<wpwrak>
ah, you want to go into PA. well, that would solve the production testing problem. veeery low volume ;-)
<wolfspraul>
and I could learn about sea shipping, which I always wanted to
<wolfspraul>
but most likely I will not do that now, just learning. there is some interface there, for sure.
<wpwrak>
and about sealing them properly, ...
<wolfspraul>
PA?
<wpwrak>
public address
<wolfspraul>
don't understand
<wpwrak>
speakers for crowds, not just your living room
<wolfspraul>
hard to say
<wolfspraul>
I like to understand the people that are passionate about speakers.
<wolfspraul>
actually they seem to say "sound system"
<wolfspraul>
which slowly makes more sense to me as well
<wolfspraul>
Friday is my next training day :-)
<wolfspraul>
Jon's friend also built a speaker that is just a solar module hooked up to a beeper.
<wolfspraul>
sparkfun would be proud of that
<wolfspraul>
so when you hold it towards the sun, it beeps
<wpwrak>
useful. so you know if it's safe for vampires :)
<wolfspraul>
and another one that allows you to listen in on the mains. you just plug it in, and the electricity drives the membrane directly.
<wolfspraul>
of course the bigger ones are connected to a typical sound setup with amplifiers etc.
<wolfspraul>
so where is copyleft hardware there? need to find out
<wolfspraul>
nothing major, just research
<wolfspraul>
people research
<wpwrak>
ah well, we all have our little hobbies :)
<wolfspraul>
well
<wolfspraul>
if you cut someone off by creating a digital yet closed wall, you remove their ability to work and innovate
<wolfspraul>
the digital wall turns everybody into consumers
<wpwrak>
the digital wall still lets you manipulate the digital side
<wolfspraul>
unless superman comes, copyleft hardware, and puts them back in control and having fun and innovate
<wpwrak>
of course, if you think digital is evil, ...
<wolfspraul>
no
<wolfspraul>
you haven't thought about the audio path
<wolfspraul>
it's not just 1) music -> 2) sound
<wolfspraul>
there's a lot in between
<wpwrak>
between what ? your ears and ... ?
<wolfspraul>
between the digital audio file download and the acoustics in the room you are in
<wpwrak>
oh, sure
<wpwrak>
if you want to do it right, you need an acoustic model of the head. put it at the correct place, with the correct orientation. then go through the frequencies and check the spectrum. etc.
<wpwrak>
then you can compensate for environmental effects. or try to. will need iterations.
<wpwrak>
(acoustic model) a physical object. a plastic head with microphones inside.
<wolfspraul>
alright. so maybe some people in this field prefer to work with open hardware, instead of magic black boxes where every new version makes them a little dumber and a little less in control.
<wpwrak>
and then you also need to consider soundwaves you pick up with your skin. get that right, too. indeed, lots of fun if you seek perfection :)
<wpwrak>
nothing wrong with that :)
<wpwrak>
but why do you need to make speakers of all things ? :)
<wolfspraul>
the innovation happens on both sides, analog and digital
<wolfspraul>
but the digital side, if not open, can easily outmaneuver the analog side
<wolfspraul>
me? I don't plan to
<wolfspraul>
the speakers we are talking about are 100% 'simple' analog designs
<wolfspraul>
actually the ones made in China are cheap and crude, which makes them interesting to a point because you can be very cheap, but still achieve something 'pretty good', compared to the very expensive systems by US or European companies
<wolfspraul>
and increasingly those are turning into fully closed system, making them inaccessible to experiments or innovation, at least by the many individuals that are hanging around and innovate on the analog side
<wpwrak>
yeah. i rarely worry about speakers. there's so much other evil in consumer electronic that comes long before them ...
<wolfspraul>
my plan for now is just to learn more about people who love sound systems, and what is important to them, and what keeps them in business or at least having fun
<wolfspraul>
there's a connection to copyleft hardware somewhere there, I think. 'connection' as in - potential customers
<wolfspraul>
wpwrak: what other evil?
<wpwrak>
"sound enhancements", poor gain control, crudeness of control of frequency characteristics, etc.
<wolfspraul>
you talk about sound now, no?
<wolfspraul>
maybe my use of the term 'speaker' is confusing and incorrect
<wpwrak>
yes. the sound system that feeds the speakers
<wolfspraul>
well sure
<wolfspraul>
that's what is the interesting part
<wolfspraul>
especially if it's controlled by powerful digital systems
<wolfspraul>
and systems that do not lock out the analog guys
<hamnegga>
antenna searchin' and thining about building best direct-tv dish dBi wifi ever.  Anyone wanna help?
<wpwrak>
hamnegga: i've heard they have a pretty good dish in arecibo :)
<hamnegga>
No, I mean, I have all the coaxial, pigtails, and a small amplifier, plus maybe adding some voltage myself to make my own direct tv/wifi antenna.  Right now for instance I'm looking at the two coaxial wires comming out of the dish, and have a splitter in my hand input = input, and the two output = -3.5dB on each.  Is that positive or loss for that one splitter there?  Not clear on dB dBi and dBm
<hamnegga>
as far as I know -3.5dB is positive when using network monitoring applications.
<wpwrak>
pheee, sorry, you went right over my head :) i think DocScrutinizer could help you to bring clarity into this. but i'm not sure he's around
<wolfspraul>
xiangfu's notebook hdd broke, good reminder to run my backup :-)
<wolfspraul>
xiangfu: you solved your harddisk problem that fast?
<wolfspraul>
what happened? (I'm looking at my 500gb external hdd led blinking happily backing up my entire notebook right now :-))
<xiangfu>
Hi not from yesterday night :)
<xiangfu>
I am switch to a new harddisk 500GB, mine is too small 60 GB.
<xiangfu>
so I start the switch yesterday night.
<xiangfu>
ls
<xiangfu>
not fast, I start at yesterday night :)
<xiangfu>
wow this is in channel.
<wolfspraul>
oh so your disk broke, or you just switched to a new one?
<xiangfu>
the new 7200 500gb harddisk make my notebook 'quiver'
<xiangfu>
not broke, just switch to new one.
<wolfspraul>
ok, so no data loss. great :-)
<C-Keen>
is there a way to scroll on the console? I miss the page up/down keys :)
<xiangfu>
alt + pageup/down in ben nanonote
<xiangfu>
sorry shift + pageup/down
<C-Keen>
sorry which key is that?
<C-Keen>
ah the volume key
<C-Keen>
thank you xiangfu
<C-Keen>
are there still batches for UBBs around? Or do I need to order them for myself? I would just need around 10 or so, so triggering another production round might be inefficient
<wpwrak>
larsc: be careful to have a clear oral ejection path when you get to the part about "read disturb"
<larsc>
a what?
<wpwrak>
larsc: make sure that, if anything comes flying out of your mouth (depends a bit on how you react to surprises, and if this effect is a surprise to you), that it doesn't hit anything where that would be overly inconvenient :)
<wpwrak>
well, mouth or nose :)
<larsc>
like my laptop ;)
<larsc>
luckily there wasn't anything suprising
<`antonio`>
wpwrak: hi, I have three nanonote connected together and when I ping 1 of them i get a duplicate packet
<wpwrak>
hmm, that could be the ACK timing in dirtpan. have you set any debugging options in dirtpan ?
<wpwrak>
i.e., does dirtpan print anything ? or is it silent ?
<wpwrak>
if dirtpan is printing diagnostics, don't use that option :)
<wpwrak>
if it's already silent, you may want to tweak T_REASS_MS and T_ACK_MS in dirtpan.c
<wpwrak>
e.g., set T_ACK_MS to 200 and T_REASS_MS to 1000
<wpwrak>
the duplicates are a bit surprising, though, because they come quickly
<wpwrak>
but let's see what relaxing the timing accomplishes
<`antonio`>
wpwrak, ok i'll do it now and let you know
<`antonio`>
wpwrak, it didn't solve, actually is now is worse: 15 packets transmitted, 15 packets received, 216 duplicates, 0% packet loss
<`antonio`>
more exactly: 8 packets transmitted, 8 packets received, 40 duplicates, 0% packet loss

<`antonio`>
wpwrak, actually there are three dirtpan per peer, in this mesh, when I ping to one device it creates duplicate for all the others as well
<`antonio`>
and the trick with T_ACK_MS to 200 and T_REASS_MS to 1000
<`antonio`>
did not solved anything
<wpwrak>
hmm, so you have 3 nodes ? let's name them A, B, C. then A should run a dirtpan that talks to B and one that talks to C.
<wpwrak>
B should run one for A and one for C. etc.
<wpwrak>
maybe you just have a lot of old dirtpans :) maybe  killall dirtpan  then launch just the ones you need
<wpwrak>
or have you added anything that does data duplication/forwarding for the mesh ?
<`antonio`>

two more to come...
<`antonio`>
A is the coordinator, B and C the nodes, A dirtpan is launched to B and C, B only to A and C to A.
<`antonio`>
so if from A I ping B I will have also have two duplicates
<wpwrak>
`antonio`: okay, then the duplicates are very weird.

for coordinator is 10.0.0.10 all the other start from 10.0.0.1
<wpwrak>
so A, the coordinator is 10.0.0.10, B is 10.0.0.1, and C is 10.0.0.2 ?
<wpwrak>
is there any special mesh forwarding/routing software on those nodes ? or are they just regular bens with my wpan stuff ?
<wpwrak>
`antonio`: if all should be "normal", please stop the dirtpan on B and start it again with the option -d
<wpwrak>
it will then print a few characters for each frame it sends/receives, indicating what it does and why
<wpwrak>
ping -c 1 ...  should be enough (sends just a single ping)
