[00:02] <fnoble> edmoore: had any ideas?
[00:03] <edmoore> not on spi
[00:03] <edmoore> i have had a chinese tho, which was unplanned
[00:03] <edmoore> reading about this spread spectrum stuff
[00:03] <Laurenceb_> http://www.tapr.org/images/g1pvz/ddl_blkdia.jpg
[00:04] <Laurenceb_> is a good diagram of the timing control
[00:06] <edmoore> fnoble: any revelations?
[00:06] <fnoble> nope
[00:07] <fnoble> does anyone on here have experience using mmc/sd cards over spi?
[00:07] <Laurenceb_> yes
[00:07] <Laurenceb_> I've done it lots of times
[00:08] <Laurenceb_> but not at very low level, always using existing code
[00:08] <fnoble> well, im using a library
[00:08] <Laurenceb_> cool
[00:08] <fnoble> but getting strange results
[00:08] <Laurenceb_> are the voltages ok?
[00:08] <fnoble> i had to recode the hardware layer though
[00:08] <Laurenceb_> hmmm
[00:08] <Laurenceb_> what speed?
[00:09] <Laurenceb_> what processor?
[00:09] <fnoble> erm, its a dev board, so the physical connection will be ok
[00:09] <Laurenceb_> right
[00:09] <Laurenceb_> processor?
[00:09] <edmoore> it was 15mhx wasn't it?
[00:09] <fnoble> lpc2148, 60mhz cpu clock, running the mmc at 100khz
[00:09] <edmoore> lpc2148
[00:09] <Laurenceb_> cool
[00:09] <edmoore> whoops wrong window
[00:09] <fnoble> have tried the mmc at a bunch of different speeds
[00:09] <Laurenceb_> are you sure its not addressing it too fast?
[00:10] <Laurenceb_> right
[00:10] <fnoble> ill, try clocking it REALLY slow then
[00:10] <fnoble> :)
[00:10] <Laurenceb_> hehe
[00:10] <Laurenceb_> I've only ever used avr, so you cant go above 10Mhz clock
[00:11] <edmoore> its *really* odd tho
[00:11] <edmoore> getting the wrapper but none of the data within it
[00:12] <Laurenceb_> hmm odd
[00:12] <Laurenceb_> does your card work?
[00:12] <edmoore> well, getting the end of sector bytes anyway
[00:12] <edmoore> this is an option...
[00:12] <edmoore> fnoble: spark have sold out of the cheap ones now
[00:12] <Laurenceb_> can you try it on a pc/mac
[00:13] <edmoore> it works on there, but it's a microsd so it could be wierd about the spi protocol
[00:13] <Laurenceb_> what size caps can you get?
[00:13] <fnoble> and it responds to the handshake stuff as far as i can tell
[00:13] <Laurenceb_> is there a 7.something
[00:13] <Laurenceb_> uF
[00:14] <Laurenceb_> oh 6.8uF nvm

[00:51] <fnoble> this is where our code is failing
[00:52] <fnoble> if its the goddamn card i will kill someone
[01:01] <edmoore_> fnoble: i said this at the beginning????
[01:01] <edmoore_> 2gb cards don't mount properly
[01:01] <edmoore_> we found that out with nova2
[01:01] <fnoble> this is only 1gb though
[01:02] <edmoore_> oh right..... thought you'd have made mor of a fuss if it was 2gb
[01:02] <fnoble> and the library is supposed to be compatible with sdhc
[01:02] <fnoble> dunno if 2gb means sdhc or something else
[01:03] <edmoore_> might be worth finind a 512 sd card
[01:03] <edmoore_> just to be safe
[01:03] <fnoble> mmm
[01:04] <edmoore_> might go to bed. tomorrow is another day and that

[07:33] <natrium42> spirit of knoxville doing well
[07:36] <jcoxon> oh good point
[07:36] <jcoxon> i forgot about that
[07:36] <jcoxon> got caught up with the shuttle launch
[07:37] <jcoxon> are you tracking it?
[07:40] <jcoxon> wow, they have a stunning dashboard for following it
[07:42] <natrium42> yep, they did a good job on it
[07:43] <jcoxon> i want it :-p
[07:46] <jcoxon> well lets hope they make it accross

[08:06] <edmoore> oooh
[08:06] <edmoore> that's an awesome applet
[08:07] <jcoxon> indeed it is
[08:07] <edmoore> 195 kph?
[08:08] <edmoore> christ
[08:08] <jcoxon> yeah
[08:08] <jcoxon> not bad
[08:08] <jcoxon> :-p
[08:12] <edmoore> so how big is thier radio?
[08:12] <jcoxon> there are 2
[08:13] <jcoxon> VHF on 144.39mhz i'm not sure the power
[08:13] <edmoore> 3oomW
[08:13] <jcoxon> HF 10.257mhz at 3W
[08:15] <edmoore> wowee!
[08:15] <edmoore> if only
[08:16] <edmoore> do they have any uk listeners?
[08:16] <jcoxon> not sure
[08:16] <edmoore> oh, the 3w is illigal in the states too
[08:17] <edmoore> they just turn it on over the sea
[08:17] <edmoore> lolzor
[08:19] <jcoxon> the project that it'll land
[08:19] <jcoxon> oops
[08:19] <jcoxon> its projected to cross france
[08:20] <jcoxon> its really cool
[08:20] <jcoxon> wish we could do something like that

[08:22] <edmoore> yeah definitely
[08:22] <edmoore> i really do like that software
[08:23] <jcoxon> the cu wireless soc will have a 30m band receiver
[08:23] <edmoore> the mysql stuff is interesting - exactly the kind of stuff we'd have to look at for an engineering-department tracking antenna
[08:27] <jcoxon> yeah
[08:31] <edmoore> awesome stuff
[08:31] <edmoore> their balloon design is interesting
[08:31] <edmoore> if they can get away with it
[08:34] <jcoxon> what do you mean?
[08:34] <jcoxon> the tetra sort of style?
[08:37] <edmoore> yeah
[08:37] <edmoore> minimises construction time
[08:37] <jcoxon> its quite often used for solar balloons

[15:40] <fnoble> perhaps
[15:40] <fnoble> in a bit, still need to have lunch
[15:40] <edmoore> oh god fergus
[15:40] <edmoore> sort it out
[15:41] <edmoore> push through till supper
[15:41] <edmoore> good for the soul
[15:41] <fnoble> to be honest, still need to have breakfast
[15:41] <fnoble> lol
[15:41] <edmoore> there are mini pizzas here
[15:42] <edmoore> massive grease, so good for hitting the spot
[15:46] <edmoore> I want to beat this fat32 today fergus
[15:46] <edmoore> i have a serious caffeine issue and it needs some C to be let out upon
[15:46] <edmoore> i warn thee
[15:54] <fnoble> ok ok, ill come
[15:54] <fnoble> give me a second or two
[15:54] <fnoble> ill be about an hour probably
[15:55] <edmoore> ok
[15:55] <fnoble> see if you can borrow another small sd card
[15:55] <edmoore> i;'ll be gyming at 10 for a while, i warn ya
[15:56] <edmoore> need to break myself
[15:56] <edmoore> hi mc-
[15:57] <fnoble> mmm.. im supposed to be going out to eat at about 6
[15:57] <fnoble> doesnt give us much time
[15:57] <fnoble> unless you want to come down
[15:58] <edmoore> i would say yes, but it'd be a lie. why did you pick queens goddamit?
[15:58] <fnoble> well, i should be asking you why you picked churchill
[15:58] <edmoore> this will be so much easier when we've made up the pcbs and don't necessarily need each other
[15:58] <edmoore> no, because you came here knowing that i'd be at churchill
[15:59] <edmoore> you're a 1a person, so you gotta adapt to the status quo
[15:59] <fnoble> i didnt know you when i applied!
[16:00] <fnoble> anyways, ill have a shower and then see how its going

[16:41] <edmoore> could stick norobots.txt in i spose

[16:41] <mc-> I'll check with him
[16:42] <mc-> btw, was reading the logs, I've got some cheap 50MHz receivers, that would be perfect for sending cutdown commands.

[17:25] <edmoore> yeah amazing
[17:25] <edmoore> they've broken the distance record
[17:25] <edmoore> they'r e abit worried about having enough ballast to last the night, though
[17:25] <natrium42> ballast is only used during the night?
[17:26] <natrium42> not sure i entirely understand why ballast is needed
[17:26] <natrium42> it's cold at night, so they dump some water to keep the altitude
[17:26] <natrium42> but in the day, it should rise higher
[17:27] <natrium42> so it's OK
[17:27] <natrium42> why dump again?
[17:28] <edmoore> it'll get cold again at night
[17:28] <edmoore> the helium is diffusing out comnstantly too - not enormously, but enough to make a difference
[17:28] <natrium42> so it will get to the previous night level
[17:28] <natrium42> oh, so the problem is that helium is being lost
[17:28] <edmoore> yeah
[17:28] <natrium42> i see, that makes more sense indeed
[17:29] <natrium42> it diffuses through the envelope?
[17:30] <natrium42> not possible to do impermeable envelope?
[17:32] <edmoore> well
[17:33] <edmoore> ultra high density polyethylene is what is used because it's so tightly packed, so can stop he diffusing better than mst things
[17:33] <edmoore> but it ain't perfect
[17:37] <natrium42> is latex better?
[17:37] <mc-> it's difficult to make an impermeable envelope for helium atoms since they are small
[17:38] <natrium42> i.e. with non-zero pressure balloons
[17:44] akawaka (n=akawaka@external.treyarch.com) joined #highaltitude.
[17:46] <akawaka> what is your average rate of descent?
[17:47] <mc-> it's more important to not drop out of the jetstream, rather than looking at the rate of descent
[17:49] Hiena (n=Hiena@81.93.195.181.datatrans.hu) joined #highaltitude.
[17:49] <Hiena> Good evening!
[17:51] <mc-> I wonder if it's possible that a balloon drops out of the jetstream overnight, and then rejoins it the next day? Then no ballast would be needed?
[17:52] <natrium42> but it would still lose helium, no?
[17:52] <mc-> yes, so it wouldn't be so high over time, but as long as it got back into the jetstream, it might not matter?
[17:53] <mc-> or it could carry less ballast
[17:54] <natrium42> edmoore, hydrogen molecules have larger radius, would they escape too?
[17:54] <edmoore> dunno - might work better
[17:54] <edmoore> not sure
[17:55] <mc-> I thought hydrogen was smaller than helium?
[17:55] <mc-> 1 proton?
[17:55] <natrium42> it's also possible to store hydrogen through a metal hydride and release it periodically
[17:55] <natrium42> mc-, but it's H2
[17:55] <natrium42> two hydrogen atoms + the distance between
[17:56] <mc-> interesting, so you could electrolyse some water, to make some more H2, rather than ballast?
[17:56] <natrium42> electrolysis uses too much power, i am thinking about using a metal hydride and a chemical reaction to release the hydrogen from it
[17:56] <mc-> even better
[17:57] <natrium42> http://en.wikipedia.org/wiki/Hydrogen_storage
[17:58] <natrium42> looks pretty complicated, unfortunately
[18:00] <natrium42> probably just easier to have a small hydrogen tank
[18:02] <Hiena> Actually the hydrogen goes through the materials too.
[18:02] <natrium42> hrm, i wonder what the rate of loss would be
[18:04] <Hiena> Half party ballon/night.
[18:04] <natrium42> lol
[18:04] <natrium42> i like this unit system :)
[18:05] <natrium42> a thermonuclear source would solve everything
[18:06] <natrium42> i bet Laurence can get one for us
[18:06] <Hiena> It's reliable. I used to hunt hydrogen filled party balloons with RC planes.
[18:06] <natrium42> sounds like fun
[18:07] <natrium42> don't they escape too fast though?
[18:07] <natrium42> i should try it
[18:09] <Hiena> Nope. The key is the balance. If you adds enough weigh, they will slow down. Also some fast plane recommended. I used COX powered, 200g, 60 cm wingspan funfly and 2.5 ccm combat planes.

[18:09] <Laurenceb> hi all
[18:10] <natrium42> hey Laurenceb, i was just talking about you
[18:10] <natrium42> [14:06] <natrium42> a thermonuclear source would solve everything
[18:10] <natrium42> [14:06] <natrium42> i bet Laurence can get one for us
[18:10] <Laurenceb> haha
[18:10] <natrium42> come on, your department already got you thorium
[18:10] <Laurenceb> I have potassium nitrate
[18:10] <Laurenceb> and thorium
[18:10] <natrium42> more thorium would do :D
[18:11] <Laurenceb> hehe
[18:11] <Laurenceb> just been doing flow tests
[18:11] <Laurenceb> its really interesting
[18:11] <Hiena> Laurenceb, i have tons of radon. I gives you for free.
[18:11] <akawaka> your real name is lawrence livermore?
[18:11] <Laurenceb> lol
[18:11] <Laurenceb> the ioniser current drops right off
[18:12] <natrium42> Hiena, bah, radon is useless :P
[18:12] <Laurenceb> once a certain amount of aerosol has been deposited
[18:12] <natrium42> i have some in my basement
[18:12] <natrium42> nah, not really, at least i hope not
[18:12] <natrium42> it's well ventilated
[18:12] <Laurenceb> unfortunately thats too little to measure very well with a balance
[18:13] <natrium42> Laurenceb, are you getting a particle count too?
[18:13] <Laurenceb> I'm sure it would be useful for something... say a dust exposure meter for workers
[18:13] <Laurenceb> we were, but that instruments not flying on the balloon
[18:13] <natrium42> ah, gotta leave something for next time :D
[18:14] <Laurenceb> I might start up a business making dust exposure meters :P
[18:14] <Laurenceb> with all the health and safety regulations, there would be lots of business
[18:15] <Hiena> Chould i offer my workshop as test chamber?
[18:15] <natrium42> haha
[18:15] <Hiena> -h
[18:15] <natrium42> i want to be a tester too
[18:15] <natrium42> :P
[18:15] <natrium42> so much dust here...
[18:15] <Hiena> Yup.
[18:16] <Laurenceb> it seems fairly easy to make an extremely small HV supply
[18:16] <Laurenceb> and I didnt realise that the ionisation current tells you the total aerosol deposited
[18:16] <Hiena> Just make 60 turn on an average relay coil.

[18:35] <Laurenceb> my supervisor wants about 5 different diagrams of aerosol collection schemes for tomorrow :(
[18:36] <Laurenceb> electric hang glider? amazing
[18:36] <Hiena> Not so much. I rather calls it as a fiery, sparkling stunt.
[18:38] <Hiena> 15 kg Li-Po battery, 120 Amps mean current, 6 kW motor, and a brainless pilot/sponsor.
[18:41] <Hiena> But hey, he is paying for it...;)

[18:58] <akawaka> anyone know how to convert the data this site outputs: http://nearspaceventures.com/w3Baltrak/readyget.pl into something google earth can read?
[18:58] <edmoore> can you give a demo output file?

[19:01] <edmoore> yeah, fair enough
[19:01] <edmoore> don't know of anything myself
[19:01] <edmoore> might be a nice excuse to learn python
[19:01] <jcoxon> ooo that would be easy
[19:02] <jcoxon> so you'd feed it in, split by commas
[19:02] <edmoore> jcoxon gets excited
[19:02] <jcoxon> then rebuild as a kml file
[19:02] <akawaka> yeah, its not difficult
