[07:31] <eroomde> morning all
[07:37] <Upu> morning
[07:48] <fsphil> that it is
[07:52] <eroomde> any german speakers?
[07:53] <Upu> nien
[07:53] Action: Upu gets his coat
[07:53] <eroomde> i don't often travel to countries where I know completely 0 of the language
[07:53] <eroomde> except sweden and norway where they all speak better english than I do
[07:53] <eroomde> so I have an unusual paic
[07:53] <eroomde> panic*
[07:54] <Upu> I suspect as with most European countries you can get by in English
[07:54] <Upu> however in all fairness I've never been to Germany
[07:54] <eroomde> i hope so in berlin.
[07:54] <eroomde> but france and switzerland are very frequently english free
[07:54] <Upu> Done just about everywhere but
[07:54] <Upu> business or pleasure ?
[07:55] <eroomde> pleasure
[07:55] <eroomde> sat-wed
[07:55] <Upu> cool
[07:55] <eroomde> my friend from university moved there just after graduating, and she's leaving in april so I thought I'd go out there now
[07:56] <eroomde> free board 'n' all that
[07:56] <Upu> aye
[07:56] <eroomde> and squeezyjet are getting me there and back for about the same as an overnight train ticket from cambridge to my home!
[07:56] <Upu> when are you going ?
[07:57] <eroomde> 5am sat :)
[07:57] <Upu> still time to break out Rosetta Stone then :)
[07:57] <eroomde> :p
[08:04] <natrium42> < eroomde> any german speakers?
[08:04] <natrium42> sup?
[08:06] <eroomde> is there a german equivalent to sillily gleedful expressions of gladulation
[08:07] <eroomde> like the french 'typer-mega-top!'
[08:07] <eroomde> hyper*
[08:08] <eroomde> or 'weeeeeeeeeeee! super cool!' in english
[08:08] <natrium42> super geil
[08:09] <natrium42> "super cool" works too
[08:09] <natrium42> germans like to borrow words :)
[08:10] <eroomde> ta :)
[08:11] <natrium42> np
[08:13] <natrium42> eroomde: http://nig.gr/4FC
[08:14] <natrium42> "The food and medicines were delivered in light-weight baskets tied to balloons with timers programed to release the items above the target areas in the impoverished North"
[08:15] <eroomde> wow!
[08:15] <natrium42> think they used hot air?
[08:16] <natrium42> might produce fire dangers
[08:16] <natrium42> so probably hydrogen or helium
[08:16] Action: natrium42 runs predictor on north korea
[08:18] <natrium42> http://habhub.org/predict/#!/uuid=db645e964f6ec7624d5249ddddbf37de0bfccb52
[08:18] <natrium42> huh, what
[08:18] <natrium42> how did that work?
[08:19] <natrium42> somthing doesn't add up in that story
[08:19] <natrium42> maybe they used ground winds?
[08:20] <natrium42> or maybe they launched from sea
[08:20] <eroomde> yeah perhaps the sea
[08:21] <eroomde> but equally one can't really get to the north

[08:31] <eroomde> natrium42: maybe we've spotted the conspiracy. Reuters didn't reckon with its readers having the appropriate software
[08:32] <eroomde> it's all just south korean propaganda
[08:34] <x-f> wind may have changed since
[08:35] <eroomde> there's also that
[08:35] <eroomde> but the former postulate is the more exciting one so lets run with it
[08:38] <jgrahamc> Having come into this conversation half way... one wonders what the hell you guys are talking about!
[08:51] <eroomde> http://nig.gr/4FC
[08:51] <eroomde> predictor says no
[08:51] <eroomde> (e.g. http://habhub.org/predict/#!/uuid=db645e964f6ec7624d5249ddddbf37de0bfccb52)
[08:51] <StrayVoltage> "Computer says nooooo"
[08:52] <eroomde> 'zactly
[09:02] <jgrahamc> Does anyone know if those guys doing the balloon to photograph Discovery were successful?
[09:05] <eroomde> not heard yet
[09:06] <eroomde> masterchef is about as silly a tv show as has ever been broadcast. it's its own way its more ludicrous than all those japanese game shows that involve hoisting people above a vat of snakes by their nostrils.
[09:07] <jgrahamc> Ah, looks like they haven't recovered yet.

[10:32] <Laurenceb> did the shuttle photography balloon guys have any luck?
[10:33] <x-f> 11:07:38 <jgrahamc> Ah, looks like they haven't recovered yet.
[10:33] <x-f> 11:07:38 <jgrahamc> http://twitter.com/questforstars
[10:33] Action: Laurenceb learns to scrollback
[10:40] <x-f> their tweet says that they lost cell signal, when the payload reached 34k feet (~10 km)
[10:41] <x-f> such long vertical range for cell tower signal is common for american CDMA networks, or it might apply to GSM as well?
[10:46] simon__ (~simon@phantom.mpfh.co.uk) joined #highaltitude.
[10:46] Simon-MPFH (~simon@phantom.mpfh.co.uk) left irc: Read error: Network is unreachable
[10:52] <SpeedEvil> It may apply to GSM
[10:52] <SpeedEvil> The limit isn't really the technology
[10:52] <SpeedEvil> GSM can work up to 15km.
[10:53] <SpeedEvil> The problem is that GSM towers have - for obvious reasons - as do CDMA towers - antennas with lots of gain.
[10:53] <SpeedEvil> They are designed to put all of the power into a narrow band just around the horizon.
[10:54] <SpeedEvil> This means that there is almost no, or negative gain, going upwards.
[10:54] <SpeedEvil> Everything depends on the installation - pretty much.
[10:58] <x-f> thanks for explanation, SpeedEvil

[14:33] <Darkside> fuuuuck, i just got a short on my PSU
[14:34] <jgrahamc> Hey NigeyS. I sent you the Foundation Licence guide today.
[14:34] <NigeyS> hey, and many thanks, i look forward to a good read :D
[14:34] <NigeyS> Darkside, how the heck you manage that?!
[14:35] <jgrahamc> Also did a freeze test of my Mylar film last night: http://blog.jgc.org/2011/02/gaga-1-another-little-freeze-test.html
[14:35] <jgrahamc> The glue I was using is repositionable glue safe for polystyrene as we discussed yesterday
[14:35] <NigeyS> oo, i spent 3 hours doing the lining last night, its horrid stuff to work with lol !
[14:36] <jgrahamc> I did it by cutting squares out using a stencil that I made from cardboard and then pasting in the six pieces separately
[14:37] <NigeyS> ahh i didnt use a stencil, perhaps i should have, but its complete and ready for more work later today :D also found some acrylic paint, nice and pink!
[14:38] <jgrahamc> Brilliant. I found that sanding the polystyrene with fine sandpaper helped the paint to stick.
[14:39] <NigeyS> ahh yes i remember now i read that on your blog, think i will copy your idea there.

[14:42] <NigeyS> indeed, do you think the papers will be put online ?

[15:07] <Darkside> fsphil: i'm not testing it in the best location tho
[15:08] <Darkside> m kind of afraid of wiring up the amplifier without an antenna attached, so i cant move it far away or i cant get signal
[15:08] <StrayVoltage> Lunar_Lander: Probably exactly the same.
[15:08] <Darkside> i've got a HF transmitter, with a chunky amp in the box
[15:08] <Darkside> outputting about half a watt
[15:09] <Darkside> 14080KHz, hell, you guys in the UK might be able to make it out
[15:09] <Lunar_Lander> cool
[15:09] <Darkside> depends what kind of skip i get
[15:10] <Lunar_Lander> ionosphere FTW Darkside
[15:10] <Lunar_Lander> xD
[15:10] <Darkside> yup
[15:10] <Darkside> its gonna be a vertical 20m dipole
[15:10] <Darkside> so, 10m long
[15:10] <Lunar_Lander> wow
[15:10] <Lunar_Lander> that is BIG
[15:10] <Lunar_Lander> xD
[15:10] <Darkside> i was originally going to use 40m, but thats not going to happen this time
[15:10] <Lunar_Lander> so you have a wavelenghth of 20 m
[15:10] <Darkside> i couldn't get a filter working in time, so i had to use an existing filter, for 20m
[15:11] <Lunar_Lander> as lambda/2
[15:11] <Lunar_Lander> ?
[15:11] <Darkside> yes
[15:11] <Lunar_Lander> ah
[15:11] <Darkside> 20m is lambda
[15:11] <Lunar_Lander> yeah
[15:11] <Darkside> and i'm using a half-wave dipole
[15:11] <Lunar_Lander> ah
[15:11] <Lunar_Lander> and sometimes you need lambda/4 and there is also lambda*5/8

[15:16] <Darkside> but its a ublox, so its meant to be fast, right?
[15:16] <Lunar_Lander> ah
[15:16] <Darkside> ok, its got time
[15:16] <Darkside> thats good
[15:16] <Darkside> its getting some sort of data
[15:18] <Lunar_Lander> yeah

[15:37] <jgrahamc> Original naming idea: http://blog.jgc.org/2010/07/gaga-1.html Gagarin's first flight to space was April 1961 (i.e. 50 years ago)
[15:37] <Lunar_Lander> btw Darkside
[15:37] <Lunar_Lander> ohh la laa sounds to me like "Ulla"
[15:38] <Lunar_Lander> which is the name of my ex-gf's mom
[15:38] <Lunar_Lander> so I don't like that song
[15:38] <Lunar_Lander> xD
[15:38] <x-f> jgrahamc, but then you should wait till April 12th!
[15:38] <Lunar_Lander> yeah and 30 years of STS-1 jgrahamc
[15:38] <Laurenceb> is the transatlantic flying?
[15:38] <jgrahamc> Lunar_Lander: good one. I remember that launch well.
[15:38] <Lunar_Lander> yeah
[15:38] <jgrahamc> x-f: If the weather isn't right then it might be that day.
[15:39] <Lunar_Lander> I actually hoped that STS-134 would also be around April 12
[15:39] <Lunar_Lander> because then there would have been 30 years between the beginning and the end of the shuttle

[15:42] <Lunar_Lander> yea
[15:44] <fsphil> I wouldn't mind seeing any rocket launch, but the last shuttle mission would be pretty special

[17:27] <russss> StrayVoltage: incidentally I've been reading about the ATV guidance system while I'm meant to be working. It turns out that below 1m away from the ISS there is *no* action that could be performed in time to stop the two vehicles hitting each other. So the crew actually can't do anything.
[17:27] <russss> this presentation about it is really interesting. http://www.congrex.nl/08a11/presentations/day1_S02/S02_03_Cislaghi.pdf
[17:29] <russss> it has some properly good detail about the docking adaptor.
[17:29] <GroupO> I have been putting together a board and gps and running a code from a guy in the - im getting a "failed" reading for my ack response
[17:30] <GroupO> does that mean it cant communicate with the gps, or the gps cant locate a satallite?
[17:33] <Dan-K2VOL> thank you StrayVoltage, had stepped away
[17:33] Simon-MPFH (~simon@phantom.mpfh.co.uk) joined #highaltitude.
[17:36] <Dan-K2VOL> russss well, that's like saying that when you're coupling up train cars to eachother, for the last 1m there's nothing that can be done to stop them from hitting eachother - it's momentum at that point, in a system with a lot of intertia, and a weak power drive
[17:36] <russss> yep
[17:36] <russss> but I think the discussion was between whether the crew "can't" or "shouldn't" do anything.
[17:36] <russss> and the answer is can't
[17:37] <russss> I wonder what kind of momentum a fully-loaded ATV going at 10cm/sec transfers to the ISS.
[17:38] <Dan-K2VOL> which is harder than it looks, with the american coupler system anyway, I used to work on a train line that had old rusty couplers, and it would sometimes take 4 or 5 hits to get them to latch. With passengers on board wandering around, it always made me very nervous cause I'd have to come at it harder and harder each time with the engine. Eventually people would get knocked down and I'd get complaints
[17:38] <StrayVoltage> russss: Ooh. Thanks for the linky. :)
[17:38] Action: russss hopes the ISS docking adaptor isn't rusty ;)
[17:38] <Dan-K2VOL> haha
[17:38] <Dan-K2VOL> me too
[17:41] <russss> the interesting thing is that the docking probe is pretty symmetrical, so the rotational alignment has to be pretty precice to get all those connections in the right place.

[19:01] <Dan-K2VOL> morning
[19:01] <Zuph> How's life Dan?
[19:01] <gb73d> what happened to the 7mhz balloon last weekend ?
[19:02] <Dan-K2VOL> oh good, looking at biodegradable films for balloons
[19:05] <Zuph> Now you see why I marked "make sure Dan doesn't get distracted" as Unfinishable :-p
[19:05] <Zuph> That looks like a potentially interesting project. Thinking PVA?
[19:11] <SpeedEvil> Latex is biodegradable.
[19:13] <Zuph> The reason Dan mentions this: The local library has approached our Hackerspace asking us if we want to teach some cool classes for children/teen summer programs.
[19:13] <Zuph> There's an ordinance in the city that bans the intentional release of latex and mylar balloons.
[19:14] <Zuph> Under the auspices that they could kill dolphins. There's a pretty hefty fine associated too.
[19:15] DB10 (~chatzilla@host86-161-176-158.range86-161.btcentralplus.com) joined #highaltitude.
[19:16] <Zuph> I don't want to put words in Dan's mouth, but I imagine he's thinking that with the backing of the library, and a balloon that rapidly dissolves, a waiver would be granted :)
[19:17] <Zuph> This ordinance is one of many reasons we're not launching in town. While our balloon isn't latex or mylar, the concern of ending up in the Atlantic definitely fits with the spirit of the law.
[19:18] <SpeedEvil> I wonder about cellophane
[19:18] <Dan-K2VOL> haha what a loud balloon that would be
[19:18] <SpeedEvil> It does dissolve in water, but I don't know how fast
[19:19] <Dan-K2VOL> the tear strength of that is really low though isn't it?
[19:19] <SpeedEvil> Probably.
[19:20] <Dan-K2VOL> could see though, it's probably available in wide widths
[19:20] <Dan-K2VOL> it's for a solar balloon

[19:22] <Zuph> Dan-K2VOL: Also, I have potentially bad news.

[19:26] <Zuph> x-f: Before yesterday, that was completely arbitrary.
[19:26] <Dan-K2VOL> that's ok zuph, if it's all we non-webdevelopers can hack together
[19:27] <Zuph> As of yesterday, we reduced the number of samples that would load at once so we could filter out errored samples from the public database.
[19:27] <Dan-K2VOL> however, that's a nice well defined problem to seek help on publicly, that I bet we'd get a bite on
[19:28] <Zuph> hmm
[19:28] <Zuph> We'll have to tweak that number more before flight anyway.
[19:28] <Dan-K2VOL> Zuph we could we manually just go through and turn off samples in the public database?
[19:28] <Dan-K2VOL> in flight?
[19:28] <Dan-K2VOL> these plastics look promising: http://www.duboisag.com/
[19:29] <Zuph> We would have to do that before they got written to the public database. As soon as the public database gets written to, it gets pushed out to all our public web servers, and then each client locally caches the samples.
[19:30] <Dan-K2VOL> ah gotcha
[19:30] <Zuph> I guess realistically we could disable local sample caching, and deal with the increased load. Given the cheapness of bandwidth and CPU hours from AWS, that might be fine.
[19:32] <Zuph> Although, once again, we're shooting in the dark wrt all this web stuff :-p

[21:11] <GW8RAK> No problems
[21:11] <Lunar_Lander> btw, it is really sad that the electronics store we had in the city closed like one year ago

[21:11] <Lunar_Lander> I remember going there with my father when I was little
[21:12] <Lunar_Lander> and he would buy parts and at home we'd repair little things
[21:13] <GW8RAK> The UK used to have many local electronics stores, but now, there are a few specialist ones and a big retail chain.
[21:14] <Zuph> G'afternoon, #ha
[21:14] <GW8RAK> Ebay is a good source of cheap components.
[21:14] <Lunar_Lander> yeah
[21:14] <Lunar_Lander> hi Zuph
[21:14] <NigeyS> hey zuph
[21:15] <Zuph> GW8RAK: US used the be the same way. Of course, I'm too young to remember it :-p
[21:15] <GW8RAK> Just looked on ebay and there are 6 16MHz crystals for £1.
[21:15] <fsphil> All we have in the way of shops here is Maplin, and they're pretty poor for parts these days
[21:15] <GW8RAK> Zuph. You lucky so and so. I do remember them :(
[21:15] <NigeyS> fsphil, 17p per resistor at maplin!
[21:16] <NigeyS> i can get a pack of 50 @ RS for 50p! lol
[21:16] <fsphil> It's bad when RS are cheaper!
[21:16] <NigeyS> yes! lol
[21:16] <Zuph> Heh. Fortunately, all the big electronics houses in the US ship to here very quickly. I can get a digikey package in 2 days by regular post :-p
[21:16] <NigeyS> :o
[21:18] <GW8RAK> Has anyone in the UK come across Toby electronics in Banbury. £2.95 for p+p is quite reasonable.
[21:19] <GW8RAK> They specialise in connectors.
[21:19] <fsphil> I've ordered a few bits from them, SMA plugs mostly
[21:20] <Zuph> Just 200 miles up the road, we have Mendelson's, a 6 story warehouse in Downtown Dayton brimming with surplus electronics, motors, electromechanical stuff, among lots and lots of other cool stuff. (http://www.meci.com/)
[21:21] <GW8RAK> I'm trying to find some board to board connectors which will enable me to piggyback 3 pcb's together.
[21:21] <fsphil> mm... there are PCB headers with really long legs
[21:22] <Zuph> Use some Arduino-pedigree long lead female connectors?
[21:22] <Lunar_Lander> GW8RAK but i still have bits from that store
[21:23] <Zuph> Like this: http://www.adafruit.com/index.php?main_page=product_info&cPath=17_21&products_id=85
[21:23] <Lunar_Lander> a few holders for
[21:23] <Lunar_Lander> wait
[21:23] <Lunar_Lander> Button Cells
[21:23] <Lunar_Lander> and three solar cells
[21:23] <Lunar_Lander> :)
[21:23] <GW8RAK> Zuph, are those pins long enough to go through a pcb and mate with sockets on the next board down?
[21:24] <Zuph> GW8RAK: Yes.
[21:25] <GW8RAK> Thanks Zuph. Now I know what they are called, I can source them over here.
[21:25] <Zuph> Cool :)
[21:25] <GW8RAK> To make the flight computer more flexible, I'm thinking of a stack of boards which can be mix and match.
[21:26] <GW8RAK> One for the Picaxe, one for GPS, one for Radio, one psu etc etc.
[21:26] <Zuph> sounds like an Arduino, except for the Picaxe part :-p
[21:26] <Zuph> We're doing a similar thing for white star, but using a bus based architecture.

[21:46] <mattltm> Maybe we could fund a balloon launch as part of the opening?
[21:47] <mattltm> Would you be able to launch from a small airfield as the site is rignt next door to one. It's fun when the Apaches come in for a stop over though!
[21:47] <Lunar_Lander> yeah
[21:48] <mattltm> We know the airport manager very well so maybe it could be arranged?

[22:04] <vk5gr> i spent the morning setting up my hf receiver
[22:04] <vk5gr> had the launch been an early one I could have come - the logistics simply didnt work out with a midday launch

[22:05] <vk5gr> guessing my radio callsign give that away :-)
[22:06] <juxta> vk5gr, you should only need to select the darkside payload instead of horus
[22:06] Nick change: fsphil -> MI6VIM
[22:06] <vk5gr> hmmm my copy of fldigi doesnt ahve darkside listed as a payload?
[22:06] <vk5gr> dumb me - just had to scroll up
[22:07] <vk5gr> is there anything else to do to get it to uplink it tot he net?:
[22:08] <vk5gr> just refreshed the brower - looks like it auto uplinks - cool!
[22:08] <Lunar_Lander> yeah vk5gr :)
[22:09] <vk5gr> well - see if I can contribute to the flight in some way at least
[22:09] <MI6VIM> yea, just have it in HAB mode and the online option ticked
[22:09] <MI6VIM> pick the right payload, and it should do the rest
[22:09] <juxta> hehe yep I see you there Grant
[22:09] <juxta> there was some discussion about Darkside needing the XML to be edited
[22:09] <juxta> will clear that up with him today

[22:11] <Darkside> its not on 7MHZ now tho
[22:11] <vk5gr> ok where is it then?

[22:22] <vk5gr> well, as I said I can do it Sunday
[22:23] <vk5gr> just need to get the data from you
[22:23] <Darkside> sure
[22:23] <Darkside> are you free later tonights?
[22:23] <Darkside> tonight*
[22:23] <juxta> im sure they can recruit some plebs from media to do the editing if push comes to shove - they will probably cut their own seqeucnes etc anyway as it's for promo work
[22:23] <vk5gr> thats the problem for why i am now not coming - I have a fringe event tonight
[22:23] <Darkside> ahhh
[22:23] <juxta> what are you seeing vk5gr ?
[22:23] <Darkside> juxta: exactly
[22:24] <vk5gr> sharon wants to go to the free symphopny in the park at elder park - picnic by the torrens and all that - fireworks at the end etc to the 1812 I believe as the original composer intended (chuckle)
[22:24] <vk5gr> so we are heading in there about 6pm
[22:24] <juxta> oh cool, that will be good
[22:25] <vk5gr> as she had me booked for that before the lfight came up, unless it was going to finish early enough I didnt have a leg to stand on to knock it back
[22:26] <Darkside> vk5gr: i have a video of that on youtube :P
[22:26] <Darkside> of the 1812 with fireworks
[22:26] <vk5gr> email me the link - i'll take a look
[22:26] <Darkside> shit video though
[22:26] <Darkside> very shit video
[22:26] <Darkside> http://www.youtube.com/watch?v=fFT1AGX9ryY
[22:26] <Darkside> shit video, shit audio
[22:27] <Darkside> i was on top of the festival centre
[22:27] <Darkside> so vk5gr, been busy with LTE rollout?

[22:28] <Darkside> haha
[22:28] <Darkside> vk5gr: as long as you can get us cheap modems, its all good :P
[22:29] <vk5gr> hmmmm even I cant get that cheap a modem :-)
[22:29] <Lunar_Lander> xD
[22:29] <Lunar_Lander> is australia expensive?
[22:29] <Darkside> Lunar_Lander: relatively
[22:29] <Lunar_Lander> ah
[22:29] <Lunar_Lander> do you have ALDI?
[22:29] <juxta> it's for sale at the moment Lunar_Lander
[22:29] <Lunar_Lander> lol
[22:29] <vk5gr> well everywhere is kinda expensive for 1800MHz LTE as there are almost no networks in existence running it yet
[22:29] <juxta> $75 will get you the whole lot
[22:29] <juxta> Lunar_Lander, there's ALDI in some states, but not here in SA where we live
[22:29] <Darkside> juxta: on a shit network
[22:30] <Darkside> <3'ing Telstra
[22:30] <Lunar_Lander> ah
[22:30] <Lunar_Lander> juxta I got something for you
[22:30] <Lunar_Lander> xD
[22:30] <juxta> oh?
[22:30] <juxta> Darkside, that video wasn't all that bad :)
[22:31] <Darkside> vk5gr: hey, we should try dual-channel nextG in the trucks
[22:31] <Darkside> to get awesome bandwidth when we're in the middle of nowhere
[22:31] <Lunar_Lander> http://www.youtube.com/watch?v=iEGbVJJRZSA
[22:31] <juxta> looks like you're set for a good show tonight vk5gr
[22:31] <vk5gr> we could - but remember we have to have dual channel bases for that to work. the sites out where we often end up are still single carrier
[22:31] <vk5gr> (remember there is no one living out there except a couple of kangaroos and some rabbits)
[22:31] Zuph (~bradluyst@69.64.6.69) left irc: Ping timeout: 240 seconds
[22:32] <Darkside> vk5gr: what about between cells?
[22:32] <vk5gr> should be good
[22:32] <vk5gr> dual channel works with 2 adjacent (in frequency) carriers on the same sector of the one NodeB
[22:32] <Darkside> aaaaaaaargh
[22:32] <vk5gr> and yes juxta the video actually wasnt that bad!
[22:32] <Darkside> i thought those modems could work between cells too!
[22:32] <Lunar_Lander> does the video work juxta :D?
[22:33] <juxta> Lunar_Lander, now I see what we've been missing out on ;p
[22:33] <vk5gr> come on Darkside - didnt you pass advanced telecoms:? :?
[22:33] <Darkside> vk5gr: i got 94% >_>
[22:33] <Lunar_Lander> xD
[22:33] <vk5gr> well then there was 6% that they forgot to teach you :-)
[22:33] <Darkside> haha
[22:33] <Darkside> go bug matt about that

[22:34] <Darkside> he would have been out at the launch today if he wasn't ringing church bells :P
[22:34] <MrCraig> evening all
[22:34] <mattltm> Hi Craig
[22:34] <Darkside> vk5gr: so 20m works well in the daytime, eh?
[22:35] <vk5gr> I guess we didnt have DC-HSDPA running long enough for him to get it into the curiculum for last year :-)
[22:35] <juxta> Darkside, you have a copy of the footage from the tux flight right?
[22:35] <juxta> im out of hdd space and need to clear this SD card
[22:35] <vk5gr> i have a master copy on my database juxta
[22:36] <Darkside> vk5gr: exactly
[22:36] <Darkside> http://www.ips.gov.au/HF_Systems/1/1/1
[22:36] <Darkside> nooooooo
[22:36] <Darkside> dont tell me 20m is going to skip right OVER the eastern states today
[22:36] <Darkside> also the incidence angle is going to be low, as i'm running a vertical antenna
[22:37] <juxta> okay great thanks vk5gr
[22:37] <Darkside> should have done 30m instead of 20m >_>
[22:37] <vk5gr> looks like only Darwin will hear it
[22:37] <Darkside> :<
[22:38] <Darkside> i *could* switch to 30m >_.
[22:38] <Darkside> but i've already changed the frequency once
[22:38] <vk5gr> here's hoping that 14MHz direct path into Adelaide is fine - should be
[22:38] <shenki> good morning balloon lovers

[22:39] <vk5gr> well i have some things to do before coming back to get the receiver tuned - will be back closer to launch time
[22:39] <Darkside> ok, shower time
[22:39] <Darkside> back in a bit
[22:41] <MrCraig> Thanks jonsowman
[22:41] <jonsowman> didn't realise you were on here MrCraig
[22:41] <jonsowman> :)
[22:41] <juxta> ok im off
[22:41] <juxta> cya soon guys
[22:41] <MrCraig> hehe, just joined as I sent that email
[22:41] <MrCraig> bye juxta
[22:41] Action: MrCraig just got home from the pub - a rare outing.
[22:44] <vk5gr> juxta: vk5zm called to say he is on 70cm summertown and is about to get rolling
[22:52] <NigeyS> evening jonsowman
[22:52] <jonsowman> hi NigeyS
[22:52] <jonsowman> how are things?
[22:52] <NigeyS> pretty good, been painting the payload box :D
[22:52] <jonsowman> oh nice
[22:52] <NigeyS> i did have a Q though
[22:52] <jonsowman> go on
[22:52] <NigeyS> i was going to use 3 x aa batteries for 4.5v .. would i be better with using 4 ?
[22:53] <jonsowman> what are you powering?
[22:53] <NigeyS> ntx2, arduino mega, lassen iq, and 1 temp sensor, its all been fine with 3xaa so far, but was wondering if 4.5 was a bit on the low side
[22:54] <jonsowman> are you regulating the voltage?
[22:55] <NigeyS> yeah, theres a 3.3vreg on there, measuring that is given a fairly solid 3.27v
[22:56] <jonsowman> do you know what the reg's dropout voltage is?
[22:56] <NigeyS> ah let me check
[22:56] <Darkside> ok i'm on the side on summertown vk5gr juxta
[22:56] <Darkside> not that i can transmit >_>
[22:57] <NigeyS> jonsowman, according to the spec sheet 1v is the typical dropout
[22:58] <jonsowman> that is very high
[22:58] <NigeyS> yeah, amazingly it's sold as a low dropout vreg lol !
[22:58] <jonsowman> with that dropout, 4V5 might be pushing it a little bit, as terminal voltage will drop with temperature by some extend
[22:59] <jonsowman> the Lithiums are very good in that respect in that they don't suffer nearly as much as other battery techs
[22:59] <jonsowman> but the effect is still there
[22:59] <jonsowman> so your options are 1) use 4xAA or 2) change the reg
[22:59] <jonsowman> s/extend/extent/
[23:00] <NigeyS> i see, oki, i'll probably swap the vreg and go with 4xaa just to be on the safe side
[23:01] <jonsowman> doing both is probably unnecessary, but as you say, better to be on the safe side
[23:01] <NigeyS> yup, seems the dropout actually can hit 1.5 when at 800ma .. thats way to high
[23:02] <Darkside> <3 switchmode regilators
[23:02] <Darkside> regulators*
[23:02] <jonsowman> 800mA is loads - I don't expect you're drawing anywhere near that?
[23:02] <Darkside> the one i'm using has a -7V dropout voltage >_>
[23:03] <NigeyS> sounds like a plan Darkside :P seems amazing these are branded as low dropout though :|
[23:03] <NigeyS> jonsowman, not even close, 200ma at most iirc
[23:03] <jonsowman> NigeyS: :)
[23:03] <NigeyS> im still a bit unsure on this lassen
[23:03] <jonsowman> switch mode regs are good, but they have their place
[23:03] <jonsowman> NigeyS: oh, what's up?
[23:04] <Darkside> NigeyS: this is a dimension engineering switchmode buck/boost regulator
[23:04] <NigeyS> it seems very temprimental is getting a lock, even with a good groundplane outside
[23:04] <Darkside> i'll get about 200mA output at 12V with input voltages between 5V and 15V
[23:04] <NigeyS> Darkside, thats not fair! lol
[23:04] <NigeyS> in*
[23:04] <Darkside> heh
[23:04] <Darkside> well today it won't be much help
[23:05] <Darkside> i'm going to be drawing 700mA all through the flight
[23:05] <NigeyS> toasty!
[23:05] <jonsowman> NigeyS: I never had any issues with the iQ at all
[23:05] <jonsowman> which ant are you using?
[23:05] <Darkside> i'm seriously thinking about cutting holes in my payload to try and keep it cool
[23:05] <NigeyS> i bought the standard active antennae that was recommended from diamond point
[23:06] <NigeyS> lol Darkside .. air venst on a hab payload, who'd have thought it! :p
[23:06] <NigeyS> vents*
[23:06] <Darkside> NigeyS: well i'm using a linear amplifier
[23:06] <jonsowman> the HFL -> SMA adapter with the SMA ant?
[23:06] <Darkside> it gets nice and toasty if you don't have a well matched load
[23:06] <NigeyS> its the hfl with the ceramic square antennae
[23:07] <vk5gr> darkside - by the time you fly 14mhz will cover both east and west coasts of the continent if I am following the IPS predictions right
[23:07] <Darkside> ooh cool
[23:07] <Darkside> very very nice
[23:07] <jonsowman> NigeyS: got a link?
[23:07] <NigeyS> sure ..
[23:07] <Darkside> vk5gr: can you link me to the prediction?
[23:07] <vk5gr> the chart you gave the link for is the sounding right now - but 14MHz usually doesnt open to VK2/4/6 until later in the day
[23:08] <NigeyS> http://www.dpieshop.com/trimble-miniature-30v-unpackaged-gps-antenna-hfl-connector-5785900-replacement-p-234.html?osCsid=662706d7daf6e651b7b5ff08159d8cb6
[23:08] <vk5gr> it is the same link you sent me - just interpretting what Iam seeing differently
[23:08] <Darkside> vk5gr: ahh :)
[23:08] <Darkside> i have much to learn about the ionosphere
[23:08] <jonsowman> NigeyS: ah right OK - we used a different one on Apex
[23:08] <NigeyS> its completely random wether it gets a lock, im thinking of a hfl > sma adapter and a better sma antennae
[23:09] <jonsowman> we used this http://www.dpieshop.com/trimble-miniature-30v-gps-antenna-sma-connector-5623752-replacement-p-290.html?osCsid=662706d7daf6e651b7b5ff08159d8cb6
[23:09] <NigeyS> ah yes, thats the 1 i was looking at, might be worth it, i dont fancy losing gps for the sake of £12 and a tiny bit of desoldering
[23:10] <jonsowman> it might not be an ant issue...
[23:10] <jonsowman> I can't really say
[23:10] <NigeyS> i do have a spare gps here, but its going to die at 18km
[23:11] <jonsowman> which one's that?

[23:11] <NigeyS> i emailed them to be sure it was limited, and they confirmed it would die at altitude limit
[23:12] <jonsowman> fair enough
[23:12] <NigeyS> jonsowman, put it this way, in this room, the lassen wont get a lock, the locosys gets a lock in under 5 seconds, cold start
[23:16] <jonsowman> hmm
[23:16] <jonsowman> interesting
[23:17] <NigeyS> yeah, the house can be a bit like a faraday cage at times, but to not get a lock outside after an hour, kinda puzzling

[23:26] <spacefelix> How are ya?
[23:27] <MrCraig> Anyone have any idea the cost of a L-Size (or there about) cylinder for purchase, so that it can be refilled rather than renting?

[23:32] <MrCraig> Thanks NigeyS, but I'd presumed this was rental data rather than purchase?
