[00:00] <cellkyborg> how many baloons have you launched?
[00:01] <Darkside> project horus has launched 20 balloons
[00:01] <Darkside> i've been involved with 14
[00:01] <cellkyborg> so it's a group of people?
[00:02] <cellkyborg> who are you in general? engeneers or just hobbyists
[00:02] <Darkside> http://projecthorus.org/
[00:02] <Darkside> mostly engineers
[00:02] <Darkside> the founder, juxta, is a hobbyist
[00:03] <Darkside> but yeah, most of the group are electronic or communications engineers
[00:03] <Darkside> and we're all amateur radio operatores
[00:03] <Darkside> operators*
[00:06] Elwell (~elwell@freenode/staff/elwell) joined #highaltitude.
[00:08] <cellkyborg> are you all from australia?
[00:08] <Darkside> in project horus? yes
[00:08] <Darkside> in this channel? no
[00:09] <cellkyborg> ya in horus :)
[00:10] <cellkyborg> anyway, how accurate http://habhub.org/predict/ is?
[00:11] <Darkside> it works pretty well
[00:11] <Darkside> as always, weather conditions can and will change during a flight
[00:11] <Darkside> so the actual landing site could differ from the predicted site by many tens of km
[00:15] <cellkyborg> I see that you use antenas with GPS module. Is the signal weak or is it just to be sure?
[00:16] <Darkside> eh?
[00:16] <juxta> though more importantly the predictor relies on you inputting the correct ascent rate/descent rate/burst altitude for accurate results
[00:16] <Darkside> by gps module i mean the actual gps processing module
[00:16] Elwell (~elwell@freenode/staff/elwell) left irc: Quit: leaving
[00:16] <Darkside> while some may come with an antenna already, the ones we've been using recently don't
[00:17] <cellkyborg> uBlox 6 NEO-6Q + Sarantel GeoHelix antenna
[00:17] <Darkside> yes
[00:17] <Darkside> the NEO-6Q is just a procesing module
[00:17] <Darkside> it needs an antenna
[00:18] <Darkside> http://www.sparkfun.com/products/9566
[00:18] <Darkside> thats an example of a complete gps module, with the gps chipset and a helical antenna
[00:18] <Darkside> http://rfhead.net/data/uBloxBreakout/breakout_top.JPG
[00:19] <cellkyborg> I though you just solder module and it has enough signal already
[00:19] <Darkside> another example
[00:19] <Darkside> nope
[00:19] <Darkside> so in the picture i just linked, the metal can in the middle is the module
[00:19] <Darkside> but it has no antenna
[00:19] <cellkyborg> got it
[00:24] <cellkyborg> http://www.ublox.com/en/gps-modules/pvt-modules.html
[00:24] <cellkyborg> it says it's a module, but i can't see the antena
[00:25] <Darkside> yes
[00:25] <Darkside> 'module' can mean either just the receiver, or a complete receiver + antenna thing
[00:25] <cellkyborg> well they have the chip section
[00:26] <cellkyborg> so I assume chip is just a chip, and module is a device
[00:28] <NigeyS> http://www.flickr.com/photos/nigeys/6384643027/in/photostream
[00:28] <NigeyS> thats a module :)
[00:29] <Darkside> NigeyS: thats a module on a PCB, with an antenna :-)
[00:30] <NigeyS> :p
[00:30] <NigeyS> gps fixed btw
[00:30] <NigeyS> replaced %d with %i
[00:30] <SpeedEvil> :)
[00:32] <Lunar_Lander> :P
[00:40] <natrium42> just saw tim cook
[00:40] <natrium42> in starbucks
[00:41] <Lunar_Lander> cool
[00:41] <Lunar_Lander> who's that?
[00:43] <SpeedEvil> Rick Cook - now he might be fun.
[00:43] <natrium42> Lunar_Lander: apple ceo
[00:44] <Lunar_Lander> cool!
[00:46] <gonzo_> is that breakout board a std part, or private design ?
[00:47] <Darkside> Upu designed it
[00:48] <cellkyborg> what baloons are you using? totex?
[00:48] <Darkside> we use hwoyee
[00:50] <cellkyborg> how do you choose baloon size compared to cargo weight
[00:51] <Darkside> uhmm
[00:51] <Darkside> :P
[00:51] <Darkside> well theres a balloon burst predictor
[00:51] <Darkside> which lets you play with paramaters to see what works best

[00:59] <NigeyS> Darkside, that bug is back
[00:59] <NigeyS> that we had on picochu-1
[00:59] <Darkside> oh read
[00:59] <Darkside> dear*

[01:00] <NigeyS> duplicating
[01:00] <Darkside> damn
[01:00] <NigeyS> it has to be the tinygps lib
[01:00] <NigeyS> or at least the ver of it thats on the wiki
[01:00] <Darkside> NigeyS: are you using a ublox?
[01:00] <NigeyS> yup, ublox6
[01:00] <Darkside> goddamnit
[01:00] <Darkside> then use polled mode
[01:00] <Darkside> then you won't have these problems
[01:00] <NigeyS> i am
[01:01] <Darkside> whaaaat
[01:01] <Darkside> we never have problems
[01:01] <NigeyS> well the only thing the same as it was on picochu-1 is the tinygps lib, the codes been totally rewritten
[01:03] <Lunar_Lander> good night!
[01:03] <NigeyS> nite kev

[01:04] <NigeyS> etc etc
[01:05] <Darkside> hrmmm
[01:05] <Darkside> and you're using the modified tinygps?
[01:05] <Darkside> that supports the pubx format
[01:05] <NigeyS> yeah, its a bit old mind, dated 2010
[01:05] <Darkside> yeah thats fine
[01:05] <Darkside> again, this works perfectly for us
[01:05] <NigeyS> has comments by terry in there, from the zip file on the fsa03 page on wiki
[01:05] <Darkside> do you have the mininut code?
[01:05] <Darkside> from the mininut package i sent you

[01:14] <Darkside> that should help a bit
[01:14] <Darkside> at least to give you an ide of how we do things
[01:14] <NigeyS> well, comparing yours to what i have now, isnt much difference

[01:14] <NigeyS> so where this duplication comes from is a right mystery
[01:15] <Darkside> but there must be something going on
[01:15] <NigeyS> unless its not clearing the buffer in time ?
[01:15] <Darkside> i dunno
[01:15] <Darkside> really don't know whats going on
[01:15] <Darkside> ok i've gotta get ready to head out

[11:43] <Darkside> i don't just mean GPIOs
[11:43] <SpeedEvil> True.
[11:43] <Darkside> raspberry pi only has audio out
[11:43] <Darkside> beaglebone i just attach a I2S audio chip
[11:44] <Darkside> and i still have enough IOs tor 3 other serial devices, and a shit-ton of other IOs

[11:44] <SpeedEvil> And yes, I agree with you in principle.
[11:44] <SpeedEvil> But I can buy 5, or is it 8 pis for a beaglebone.
[11:45] <Darkside> only the tiny one costs 25 pounds or whatever it is

[11:52] <NigelMoby> Meh
[11:52] <Upu> 3.3 volts ?
[11:53] <SpeedEvil> Well - obviously
[11:53] <SpeedEvil> I guess that it doesn't require a 5V rail - meh.
[11:54] <Darkside> well its still powered from 5v
[11:54] <Darkside> but all the IOs are 3.3v
[11:54] <shenki> Darkside: pong
[11:54] <BrainDamage> the 5V is probably for usb
[11:54] <SpeedEvil> Minor inconvenience at most IMO.
[11:54] <Darkside> shenki: explain why you don't like the raspberry pi
[11:54] <Laurenceb> so it has 3.3v, 5v, usart,i2c,spi, 8 gpio
[11:54] <Laurenceb> not impressive
[11:54] <shenki> coz it's just an ARM11 soc
[11:55] <shenki> we've had ARM11 socs ages
[11:55] <SpeedEvil> No, you're going to need ADC and stuff if you want to do much more.
[11:55] Action: Laurenceb has a pile of ARM11 board
[11:55] <shenki> this one has some cool periperhals in it, esp the media accelerators
[11:55] <SpeedEvil> And the power use is going to be high - comparatively.
[11:55] <Laurenceb> *boards
[11:55] <shenki> cortex m3 is where it's at
[11:55] <Darkside> shenki: i don't need a media accelerator
[11:56] <Darkside> but i would like linux
[11:56] <SpeedEvil> Linux make some things _so_ much easier.
[11:56] <Laurenceb> *cough* DF3120
[11:56] <SpeedEvil> and yes - df3120 too.
[11:56] <SpeedEvil> But where can I buy 7 of them.
[11:56] <SpeedEvil> (neglecting...)
[11:57] <shenki> df3120 has a s3c2412; looks similar to the imx25

[12:00] <NigelMoby> I'm gonna need trackers all night if this pico floats :/
[12:00] <SpeedEvil> But - for example - usart to GPS, GPIO to 1-wire, USB-camera, audio or GPIO to radio, and you're almost done.
[12:01] <Laurenceb> i guess
[12:01] <Darkside> i'm planning on doing 2-way AX25
[12:01] <Laurenceb> but no word on DMA or interrupt support
[12:01] <Darkside> i'm gonna need audio in and out
[12:02] Action: SpeedEvil passes Darkside a $5 USB soundcard.
[12:02] <Darkside> and i'm hoping to use some decent I2S audio codecs with the beaglebone
[12:02] <SpeedEvil> (though it has I2S
[12:02] <Darkside> SpeedEvil: i don't want to be wiring up random usb crap
[12:02] <Darkside> i wand to make a proper pcb to go on the thing
[12:02] <Darkside> i'd like to work reliably, and not be a total hackjob
[12:03] <Darkside> i still don't know if the damn thing will work at low temperatures
[12:03] <Darkside> i'm a bit concerned by tims problems with the beagleboard
[12:04] <SpeedEvil> Bit of foam, and 1W will keep it toasty. :)
[12:04] <SpeedEvil> Indeed.
[12:04] <Darkside> tim had his fail twice
[12:04] <SpeedEvil> Lots of chips PLLs that I've read say 'recalibrate if over/under temp'
[12:04] <SpeedEvil> Or if change by x temp
[12:04] <Darkside> yeah that may be the problem
[12:04] <SpeedEvil> I would not be surprised if teh beagle is having lock problems
[12:04] <Darkside> we'l have to test it properly
[12:05] <Darkside> should be able to get access to a thermal test chamber
[12:06] <Laurenceb> ooh
[12:06] Action: SpeedEvil would offer his freezer.
[12:07] <Laurenceb> the camera and lcd interfaces are actually usable
[12:07] <Laurenceb> that changes things
[12:07] <SpeedEvil> You mean on bone?
[12:07] <Laurenceb> on rasperry pi
[12:07] <SpeedEvil> oh - missed that.
[12:07] <Laurenceb> http://elinux.org/RaspberryPiBoard#Interfacing_to_Raw_LCD_Panels
[12:07] <Laurenceb> looks awesome
[12:07] <SpeedEvil> ah
[12:07] <Laurenceb> can even interface with OLED

[15:06] <Rob_M0DTS> hi fsphil
[15:06] <fsphil> from when you where out of the channel?
[15:06] <Rob_M0DTS> i was thinking like last 20 lines or something..
[15:07] <fsphil> there's the entire history at http://habhub.org/zeusbot/
[15:07] <Rob_M0DTS> aha
[15:07] <fsphil> well, missing the bits when the bot was broke
[15:07] <Rob_M0DTS> super
[15:08] <Rob_M0DTS> i wil be around next weekend if you launch but Sunday will be at local rally iuntil ~2pm so might be a bit delayed!
[15:08] <fsphil> haha
[15:08] <fsphil> thanks
[15:08] <fsphil> the prediction was almost landing on top of you
[15:08] <fsphil> for last sunday
[15:08] <Rob_M0DTS> cool
[15:09] <fsphil> it will probably be early on sunday
[15:09] <fsphil> unless it's raining/snowing at the launch site
[15:09] <Laurenceb> anyone know how to determine if a device is usb2 HS or FS on windoze?
[15:09] <fsphil> either quite likely at the moment - it's gotten really cold
[15:10] <Rob_M0DTS> i will have internet at rally doing some demo for ATV so will track the progress and see what's happeing when i get out. will take tracking gear in the van just in case,
[15:10] <Rob_M0DTS> 3c at 5am when i set off for work today
[15:11] <fsphil> ooch
[15:11] <fsphil> wasn't that cold here
[15:11] <fsphil> but not far from it
[15:12] <Rob_M0DTS> cold wind just now out walking the dogs, wooley hat weather ;-)

[15:32] <Zuph> morning, Dan-K2VOL
[15:33] <Dan-K2VOL> mornin Brad
[15:35] <Dan-K2VOL> hey all we modeled our pressure data, and watched our videos, and we've determined that the odd double-peak of pressure was caused by the one-way valve opening and closing in severe turbulence in clouds around ~25,000 ft
[15:35] <Zuph> Makes sense.
[15:35] <Zuph> Get video of the turbulence?
[15:40] <Dan-K2VOL> quitr
[15:40] <Dan-K2VOL> quite
[15:41] <Dan-K2VOL> it very violent, I've never seen a balloon in a cloud so long. Wish we had a good source for cloud tops, aviation weather sources are darn difficult to sort through, and I"m a pilot. One of the reasons I don't fly any more is it felt like I was in the paper and pencil era still with all the manual labor required to find all the info you needed
[15:43] <Dan-K2VOL> we calibrated our 61 minute cutdown timer, and it fired at 56 minutes last night :-)
[15:43] <Dan-K2VOL> it actually did save our bacon.
[15:44] G0ATW (51909922@gateway/web/freenode/ip.81.144.153.34) joined #highaltitude.
[15:44] <Dan-K2VOL> the vent had stuck open enough to stop developing any differential pressure, and we were on our way to a float.
[15:44] <Dan-K2VOL> might have burst eventually, but recovery would have had to go to Pennsylvania I'm afraid
[15:46] <Zuph> heh
[15:46] <Zuph> Handy, that.
[15:46] <Zuph> Next test on a calmer day, then? :-p
[15:48] <Dan-K2VOL> no time for next tests, and thankfully we have what we need from this one.
[15:48] <Dan-K2VOL> while it didn't burst, we saw it peak at around 600 pascals pressure
[15:49] <Dan-K2VOL> and already have a workable design that replicates the Japanese vent which fully opens at 388 Pascals
[15:49] <Dan-K2VOL> so we'll open well below burst (and presumably before creep)
[15:50] <Dan-K2VOL> creep is the irreversable stretch of the plastic beyond it's elastic limit

[15:55] <eroomde> wanted to catch up on all this stuff i've missed
[15:55] <eroomde> something about double pressure peaks?
[15:55] <Dan-K2VOL> thanks eroomde!
[15:55] <Dan-K2VOL> cehck this out in the meantime: http://wiki.whitestarballoon.com/doku.php?id=analysis:spitball:1
[15:56] <Dan-K2VOL> zuph you around still?
[15:56] <Zuph> yep
[15:57] <Dan-K2VOL> could you take a look at the whitestarballoon.com server? it was working yesterday I think
[15:58] <Dan-K2VOL> I have instituted daily dropbox backups, so we're covered for content if there's any problem there
[15:58] <eroomde> Dan-K2VOL: thanks
[15:58] <eroomde> so i see this double peak thing someone mentioned
[15:58] <Dan-K2VOL> eroomde I'm about to upload some more data there
[15:58] <eroomde> could be consistant with elasto-plastic behaviour?
[15:59] <Dan-K2VOL> that's a good question that I don't know the answer to right now
[15:59] <eroomde> a version of this http://1.bp.blogspot.com/-9W6b66Ppkzc/TaRMLFIu-3I/AAAAAAAAAQk/aibv6kdWjtM/s400/Stress-Strain%2BCurve.JPG
[15:59] <Dan-K2VOL> however it does fit the behavior of the vent opening for a little bit and then closing again
[15:59] <eroomde> oh i see
[15:59] <eroomde> didn't know about no vent
[16:00] <Dan-K2VOL> yeah vent video: http://www.youtube.com/watch?v=AtWsxwfbLJ0
[16:00] <Zuph> Dan-K2VOL: Have to run to a meeting, found problem, will fix after meeting. Someone touched the server wrong.
[16:01] <Dan-K2VOL> cool, thanks
[16:01] <Dan-K2VOL> perverts
[16:01] <Dan-K2VOL> !
[16:02] <Dan-K2VOL> eroomde, that is a good question, that graph is interesting
[16:02] <SamSilver> or as Dark would say "kinky fucker"
[16:02] <Dan-K2VOL> ha
[16:02] <eroomde> so one peak at the limit of elasticity
[16:02] <eroomde> then it starts to draw
[16:03] <eroomde> until the limit of the drawing
[16:03] <eroomde> then pop
[16:03] <Dan-K2VOL> very interesting. the initial inspection of the balloon by other team members revealed no large rupture
[16:04] <Zuph> Dan-K2VOL: eroomde, we're back
[16:04] <eroomde> Zuph: thanks
[16:04] <Dan-K2VOL> but there could be a small one they didn't know was important, we may inflate it and look for small ruptures
[16:04] <eroomde> Dan-K2VOL: interesting too
[16:05] <Dan-K2VOL> thanks zuph, what was the issue? when you have time
[16:05] <eroomde> altitude/time doesn't seem to much of a big pop either
[16:05] <eroomde> a fairly constant descent
[16:05] <Dan-K2VOL> the descent was triggered by the cutdown device
[16:05] <eroomde> though that would be consistant with some kind of hole forming
[16:05] <Dan-K2VOL> which partially opened the vent valve
[16:05] <eroomde> and then no differential pressure, just helium leaking out during descent
[16:05] <Dan-K2VOL> and inverted the balloon
[16:05] <Zuph> Dan-K2VOL: Someone either updated wordpress, or updated php5. Just had to restart php-fpm.
[16:05] <eroomde> oh right
[16:05] <eroomde> lots of variables
[16:06] <Dan-K2VOL> interesting zuph, I updated wordpress last week, but had no trouble after that.
[16:06] <eroomde> are P1 and P2 measuring the same thing?
[16:06] <Dan-K2VOL> yes
[16:07] <eroomde> ok
[16:07] <Dan-K2VOL> they are both connected to internal and external manifolds
[16:07] <Dan-K2VOL> they just have different ranges

[17:38] <SpeedEvil> err - west
[17:38] <NigeyS> sorry futurity it was kinda a short flight lol
[17:38] <somnium_> how would i type that into google maps?
[17:39] <SpeedEvil> Divide the minutes by 60, to get fractional degrees, and add.
[17:39] <SpeedEvil> Then @nn,nn

[20:15] <daveake> fsphil-laptop Likely you'll launch at the weekend?
[20:16] <fsphil-laptop> that's the plan
[20:16] <fsphil-laptop> depends on the weather
[20:16] <daveake> Same here, but at the mo I think it's unlikely for me

[20:17] <fsphil-laptop> yea - the wind is pretty extreme
[20:18] <fsphil-laptop> the north sea is a possibility for mine too
[20:19] <daveake> I could launch a cheap payload and not bother chasing

[21:27] <SpeedEvil> They are comparatively rare.
[21:27] <SpeedEvil> VEry rare, even.
[21:27] <daveake> Not many. M6 toll; Severn bridge
[21:28] <fsphil-laptop> I've never seen one
[21:28] <SpeedEvil> I've seen the one over the forth bridge.
[21:28] <Lunar_Lander> oh
[21:28] <fsphil-laptop> ah wait, I was on the forth when I was very wee
[21:28] <Lunar_Lander> because they stop at one and the problem is that they only have 5 pounds
[21:28] <Lunar_Lander> or so
[21:29] <daveake> For £5 you have to stop part way and walk the rest
[21:29] <fsphil-laptop> push the car the rest of the way?
[21:29] <fsphil-laptop> noaprs jcoxon?

[21:37] <SpeedEvil> Just use the quadcopter to mount the colinear.
[21:37] <chembrow> have many guys had success with colinears? thinking of the sharman/watson/diamond X-50

[21:39] <chembrow> I believe so, in Walsall

[21:39] <fsphil-laptop> yes, or a mountain
[21:39] <chembrow> of course, I could be wrong
[21:41] <fsphil-laptop> colinear gives pretty good range for all the other amateury things

[21:52] <fsphil-laptop> lol
[21:53] <chembrow> 10,000 units in their first run

[21:54] <chembrow> or a canon
[21:54] <gonzo_> anyone got ant modulation attenuator values for the ntx2 modulkes, for 425hz?
[21:54] <gonzo_> any
[21:54] <fsphil-laptop> yea, tim got a canon talking to the beagleboard
[21:54] <chembrow> stick in a big SD card and an HD webcam, get some nice pictures
[21:54] <fsphil-laptop> most usb webcams have a rolling shutter-- make crappy pictures
[21:55] <fsphil-laptop> attenuator values?
[21:55] <chembrow> true. might get some good video tho with a 16gb card.
[21:55] <chembrow> or a USB harddrive :)
[21:56] <gonzo_> to drop the 5v ttl (or 3.3v) to a level that will give te req 425hs shift
[21:56] <fsphil-laptop> be neat to do what the horus guys are doing, fly an aprs igate

[21:58] <fsphil-laptop> the same values gives me 350hz, so it's a bit iffy
[21:59] <chembrow> I can't remember what I used but I know the theoretical was different from the actual; I think it can come down to even PCB traces having an effect
[21:59] <fsphil-laptop> best bet is to get a fixed resistor (fairly high, 20k - 100k) and use a potentiometer to find the ideal value for the second resistor
[21:59] <gonzo_> yep I did thing that phil
[21:59] <chembrow> hmm, that's a nice idea.
[22:00] <chembrow> and there was me swapping 0805 resistors in and out :p
[22:00] <daveake> I calculated mine, then measured and played with an extra R across the series one to get the shift I wanted
[22:00] <fsphil-laptop> lol
[22:01] <daveake> Proper resistors with wire, not these fiddly little boxy things :)
[22:01] <chembrow> I think I ended up at a 350hz shift. One day I'll even get around to actually launching
[22:01] <gonzo_> is the modulation linear enough to just extrapolate from the spec, down to narrow?
[22:01] <gonzo_> hehe, mine is all old school
[22:01] <fsphil-laptop> we tried that recently gonzo_, the result was about 100hz out :)
[22:02] <fsphil-laptop> but likely we did something wrong too
[22:02] <fsphil-laptop> we're not 100% sure what the deviation of the ntx2 is

[22:02] <Upu> 6000hz
[22:02] <Upu> 0-3v
[22:02] <Upu> 0.0005v per hz
[22:02] <fsphil-laptop> sure?
[22:03] <Upu> yeah I tested it with "science" (TM)
[22:03] <fsphil-laptop> nice
[22:03] <daveake> That'll never catch on
[22:03] <Upu> put an adjustable PSU on it and had a play
[22:03] <Upu> 0.2125v for 425Hz shift
[22:03] <Upu> afk walking dog
[22:05] <fsphil-laptop> hmm.. the resident mutt here is being a pain

[22:24] <fsphil-laptop> more gale force winds tonight, and I was thinking of putting the hf up again :)
[22:26] <Lunar_Lander> yea
[22:26] <fsphil-laptop> and rain
[22:26] <fsphil-laptop> lots of rain
[22:26] <Lunar_Lander> damn
[22:26] <Lunar_Lander> btw how do you like gavin and stacey?
[22:27] <fsphil-laptop> rare
[22:27] <fsphil-laptop> never watched it -- the clips I've seen don't look that good
[22:27] <Lunar_Lander> yeah
[22:27] <fsphil-laptop> plus most things on bbc three are awful
[22:27] <Lunar_Lander> I know Ruth Jones though
[22:27] <Lunar_Lander> from the movie "east is east"
[22:28] <chembrow> the missus likes it, but then she's welsh. has peculiarly fond memories of barry island!
[22:31] <fsphil-laptop> didn't see too much of wales when I was there, didnt' have time. what I did see looked good
[22:31] <Lunar_Lander> yea
[22:31] <chembrow> there's some nice bits. Cardiff and the valleys, not so much.
[22:31] <chembrow> but just round the corner to carmathenshire and pembrokeshire is really nice
[22:38] <chembrow> bed time, early start. night all
[22:38] <fsphil-laptop> sounds like a plan
[22:38] <fsphil-laptop> night!

[23:31] <Paradoxial> The purpose of time zones still somewhat eludes me
[23:31] <Paradoxial> The system is backwards in my opinion
[23:32] <Paradoxial> Instead of saying "let me change my clock when I travel there", I should be saying "let me remember that the sun rises and sets at slightly different times"
