[00:06] <gonzo_> anyone know off hand, how you seal the Qualatex foil balloon necks?
[00:10] <daveake> They self-seal
[00:10] <daveake> But put parcel tape over the opening
[00:13] <gonzo_> eve, or night dave
[00:14] <gonzo_> is the tape in the neck covered with a backing paper
[00:14] <gonzo_> to be removed?
[00:21] <daveake> No, leave the neck
[00:21] <daveake> Fill ... get the neck lift right (balanced between the 2 balloons if you're using 2)
[00:21] <daveake> then stick parcel tape completely over the tablet-shaped opening
[00:21] <daveake> then tie the string on tightly

[00:23] <daveake> What time you launching tomorrow?
[00:23] <daveake> er, today?
[00:23] <gonzo_> aiming at 1pm lift off
[00:23] <daveake> ta
[00:23] <gonzo_> but depends on wx
[00:24] <daveake> I've taken screenshots from today's flights but I'll grab some more tomorrow morning. Let me or someone else know when you're launching and I or they will clear the tracker for you
[00:24] <gonzo_> ta
[00:25] <gonzo_> should have plenty of irc and internet on site

[00:25] <daveake> I'll put my aerial up ... I should get a good signal from here
[00:25] <daveake> btw we spoke to a harbourmaster who called all the boat companies and couldn't get anyone out for us
[00:25] <daveake> We then went back and couldn't get a signal anyway from the tracker
[00:26] <daveake> We also spoke to someone who knew all the fishermen who go up and down that part of the coast, and he's going to get them to look out for a bobbing pink ball :-()
[00:26] <daveake> I mean :-)
[00:27] <daveake> If I get it back then those will be the highest photos taken from an amateur balloon
[00:27] <gonzo_> was it waterproofed?
[00:27] <daveake> Nope
[00:27] <daveake> But the SD card will be fine
[00:27] <gonzo_> it was just a few km out wasn't it? I massed the laanding
[00:28] <daveake> 1 mile from coast
[00:28] <daveake> Apparently it will go about 10 miles basically paralle to the coast, then back, and repeat
[00:28] <daveake> Each cycle will put it further out to sea
[00:28] <daveake> We spoke to an expert :)
[00:29] <gonzo_> a fisherman
[00:29] <daveake> yup
[00:29] <gonzo_> hehe
[00:29] <daveake> He's retired but knwos them all, and tracks boats for fun
[00:30] <gonzo_> with AIS?
[00:30] <daveake> He came over and asked what we were doing with the aerials and radios :)
[00:30] <daveake> pass
[00:30] <daveake> anyway ... sleep beckons! Was a looooong day
[00:30] <gonzo_> AIS is the VHF GPS paging, sort of active radar
[00:31] <daveake> and I am fu*(&&(d
[00:31] <daveake> cool
[00:31] <daveake> I'll email him and ask
[00:31] <daveake> I'll do a timelapse of the fills later
[00:31] <gonzo_> I bet, well fingers crossed it gets netted
[00:31] <gonzo_> catch you tomorrow
[00:31] <daveake> and upload the photos from my camera
[00:31] <daveake> cheers, nn

[07:16] <SamSilver> well done dave
[07:16] <daveake> Cheers :)
[07:16] <SamSilver> got an update
[07:17] <daveake> Here's hoping the fishermen of Cromer have beedy eyes :)
[07:18] <daveake> Well we tried and failed to get a boat out. Then we tried and failed to get the telemetry again. So it seems the salt water stopped the electronics.
[07:18] <SamSilver> and well done for keeping it clean .... no butt cracks!
[07:18] <daveake> :)
[07:18] <daveake> We were adjusting ourselves off-camera to make sure of that :D
[07:18] <SamSilver> well I hope your luck holds out
[07:19] <daveake> Would be great to get the photos. Not that I don't have plenty of photos, but some of these would be the highest so far
[07:19] <daveake> number10 should be uploading his photos today from ANU
[07:20] <daveake> Also 3 of us took time-lapse photos of the prep
[07:20] <daveake> Got home after midnight. I had to stop with an hour or so to go - was ready to fall asleep. We took naps then Julie drove the rest
[07:22] <SamSilver> I look forward to that

[07:23] <daveake> We sat in the fish shop eating our cod or haddock + chips. They had some kiddy toy dispensers and one caught my eye - "Fly a balloon!"
[07:23] <SamSilver> looks like you got 20 (or so) strings from 0m alti
[07:24] <SamSilver> lol
[07:24] <daveake> yeah, could have got plenty more if we'd set a yagi up on a tripod
[07:24] <Elmar_work> morning!
[07:24] <daveake> The payload was doing maybe 1mph eastwards
[07:25] <SamSilver> pic of "fly a balloon" toy?'?
[07:25] <daveake> Yes, later :)
[07:25] <daveake> Apparently the tide there goes east for 10 hours then west for 10, then repeats
[07:25] <daveake> Each repeat will send it further out to sea a little
[07:25] <daveake> Several fishing boats go that way
[07:26] <daveake> We spoke to a guy who tracks the boats as a hobby
[07:26] <daveake> He's going to speak to the boat guys today and ask them to keep a look out
[07:26] <SamSilver> with a strong onshore wind and the bit above the water line it could come to shore
[07:26] <daveake> It could
[07:26] <Elmar_work> hope it will be found soon
[07:27] <daveake> me too :)
[07:27] <SamSilver> it was heading south east it could well the head south west for 10 hours ... with an on shore wind
[07:27] <SamSilver> do you have any wind data since splash down?
[07:27] <daveake> nope
[07:28] <daveake> From yesterday ...
[07:28] <daveake> [08:56] <daveake> windy here, so I'll prolly overfill rather than risk a wet landing
[07:28] <daveake> I didn't :p
[07:28] <daveake> well I did a little and expected 5.2m/s but got 4.1
[07:30] <Elmar_work> tide and wind: http://bigsalty.com/tide-data.php?stationId=4
[07:30] <daveake> cheers
[07:30] <daveake> "bigsalty" lol
[07:30] <SamSilver> nice one Elmar_work
[07:30] <Elmar_work> indeed nice domain name ;-)
[07:31] <SamSilver> bigblow.com
[07:32] <SamSilver> would be handy .... porn site most likely taken the domain name
[07:32] <SamSilver> for wind data that is
[07:33] <oh7lzb> Yesterday I saw this cab in Helsinki: https://twitter.com/#!/hessu/status/199129638327431168/photo/1/large
[07:34] <Elmar_work> nice protocol ;-)
[07:34] <SamSilver> oh7lzb: not many peeps gonna get that, most here will
[07:36] <Elmar_work> oh7lzb: so you're the one from aprs.fi
[07:38] <oh7lzb> Yup. I hope to catch a ride on it some day :)
[07:38] <oh7lzb> I had seen AX.24 before, I think they belong to the same company
[07:40] <Elmar_work> I'm using it daily ;-) http://aprs.fi/#!call=PD3EM-9
[07:40] <oh7lzb> Excellent, I'm happy it's useful
[07:44] <oh7lzb> Taking a quick Hadoop course today at work.
[07:44] <SamSilver> Hadoop ?
[07:45] <Upu> morning all
[07:45] <daveake> morning
[07:45] <oh7lzb> Map/Reduce, parallel cluster programming
[07:45] <SamSilver> morning upu
[07:46] <Upu> hey daveake congrats on yesterday hope it turns up
[07:46] <daveake> cheers, was a fun day
[07:46] <SamSilver> did google search thanx
[07:46] <Upu> what was the ascent rate on Buzz ?
[07:47] <daveake> Weird that buzz ascent was slower than it should have been. We checked our calcs, and the neck lift was accurate we think
[07:47] <daveake> 4.1
[07:47] <daveake> calc 5.2
[07:47] <Upu> ok
[07:47] <Upu> but Mondo didn't float
[07:47] <Upu> odd
[07:47] <Upu> windy day ?
[07:47] juxta (~rootkit@ppp203-122-193-94.static.internode.on.net) joined #highaltitude.
[07:47] <daveake> Gusty
[07:47] <daveake> Still enough for neck lift measurement
[07:48] <daveake> Plenty of us there to confirm it looked neutral
[07:48] <Upu> interesting
[07:48] <daveake> We weighed the payload and chute to confirm
[07:48] <Upu> ok need food back soon
[07:48] <daveake> So really not sure where we went wrong
[07:49] <daveake> Steve had measured the filler weight including the extra amount per cm of hose
[07:49] <daveake> All checked out. Confused.
[07:53] <SamSilver> daveake: work backwards and calc what lift you did have that gave 4.1 then look for somthing that is of that weight or 2 x multipile
[07:53] <daveake> yeah
[07:53] <SamSilver> 0.5 multipile
[07:54] <SamSilver> I need another cuppa coffee before i attempt that
[07:54] <daveake> I'll do it later; brain too fried at the mo
[07:54] <SamSilver> me too
[07:54] <SamSilver> lol
[07:55] <daveake> Launches are 3 days long .... 1: Build/pack, 2: Launch/chase/recover, 3: Physically recover
[07:55] <daveake> and upload photos, make timelapse videos, etc etc
[07:55] <Upu> lol yeah
[07:56] <Upu> I still need to do the write up bit from the last launch
[07:56] <daveake> It's a lot of work isn't it?
[07:56] <Upu> yup
[07:56] <Upu> Mick was lucky
[07:56] <daveake> Blogs, QSL cards, videos, photos, FB updates, read the chat to find out what I missed ...
[07:56] <Upu> were the predictions that close to the sea to start off with ?
[07:58] <daveake> Mondo? dunno, wasn't paying any attention
[07:58] <Upu> Mondo almost went to see too
[07:58] <Upu> sea
[07:59] <daveake> Yeah, we passed within a mile of the place it landed
[07:59] <Upu> btw
[07:59] <Upu> great show on the video the only issue is your camera seemed to have issue with the bright sky
[07:59] <Upu> which means we got Alien Dave!
[07:59] <daveake> lol
[07:59] <Upu> http://i.imgur.com/9kWQE.jpg
[07:59] <daveake> Yeah I noticed
[08:00] <daveake> I'll see if I can fix the contrast
[08:00] <Upu> Also
[08:00] <Upu> http://i.imgur.com/uKwuF.jpg looks like you were trying to launch with it
[08:00] <daveake> I did test with an old webcam but it was shite
[08:00] <daveake> Might invest in something better
[08:00] <daveake> Oh good, you got that :D
[08:00] <Upu> I just got one of the higher end Creative ones
[08:01] <daveake> I was posing :D
[08:01] <Upu> though technically my work bought it :)
[08:01] <Upu> its the one we use for video conferencing
[08:01] <daveake> I may follow that precisely :D
[08:01] <Upu> wheres number10 anyway ?
[08:02] <Upu> all payloads had a great signal
[08:02] <daveake> Didn't realise the contrast was that, well, black and whute
[08:02] <daveake> Excellent
[08:02] <Upu> it was fine when most of the frame was pointing at green
[08:02] <daveake> OK
[08:02] <Upu> but as soon as you got the sky in the it struggled
[08:02] <daveake> Might be some adjustment I can make
[08:02] <daveake> But really a separate webcam would be much more convenient
[08:03] <Upu> but it was more than good enough to ensure people knew what was going
[08:03] <Upu> on
[08:03] <daveake> excellent
[08:03] <Upu> yeah the camera in the lid is hard to position
[08:03] <daveake> I should have used it again when we found ANU/CLOUD but I didn't think of it
[08:03] <Upu> I forgot on Cloud/Ava too
[08:03] <Upu> you have other things on your mind
[08:04] <Upu> like getting it out of the tree/sea/field
[08:04] <daveake> In this case it was number10's PITA brother ....
[08:04] <Upu> was he in the car with you ?
[08:04] <daveake> .... who turned up with kids, didn't speak to us at all, then went after the payload
[08:04] <daveake> Nope
[08:04] <daveake> We had to tell him to FO
[08:04] <Upu> ouch
[08:04] <daveake> number10 really doesn't like him

[08:05] <Upu> morning number10 :)
[08:05] <daveake> Just talking about your bro ... :p
[08:05] <Upu> Congrats on yesterday
[08:05] <number10> morning Upu
[08:05] <Upu> I got his brother on the webcam chat
[08:05] <Upu> alot of him :)
[08:05] <daveake> lol
[08:05] <number10> apologies
[08:06] <daveake> np
[08:06] <Upu> 06/05 12:11 guest433 : 2E0UPU - nice chatting - I am taking twins off to see if we can hook up with Dave B (Bro) probably get lost as we do not have a tracker - mind you - I bet we find a pub.
[08:06] <number10> next time he wont know there is a launch
[08:06] <daveake> He left after both you and I asked him to get out of the way
[08:06] <daveake> I guess he wanted that pub
[08:07] <number10> he was a pain - I sent him an email yesterday - dont think he will speak to me for another 5 years
[08:07] <number10> bonus
[08:07] <daveake> lol
[08:07] <Upu> lol
[08:07] <daveake> First I had to ask him to not touch the payload etc
[08:07] <daveake> Then to get out of the way of the photos
[08:07] <Upu> lol
[08:07] <daveake> Think #10 said the same at about the same time
[08:07] <daveake> Then he just left
[08:08] <Upu> sounds like for the best
[08:08] <daveake> indeed
[08:08] <number10> there is clearly a picture of him bending over the balloon payload with his hand close to the payload - when dave ask him not to touch the payload - I sent him that picture (thats the only one he'll see)
[08:08] <Upu> All launches yesterday use H2 ?
[08:08] <daveake> none
[08:08] <daveake> The man from EARS say no
[08:09] <Upu> all Helium wow
[08:09] <Upu> that an impressive height
[08:09] <daveake> So I get #1 He flight :)
[08:09] <number10> excelent
[08:09] <daveake> Yeah, I wasn't expecting more than 40.5 with H2
[08:10] <daveake> I was aiming for Michael(Mondo)'s "highest photos" recored
[08:10] <Upu> technically you got it
[08:10] <daveake> But unless I get them back then that stands
[08:10] <daveake> yeah
[08:10] <Upu> just relying on a fisherman now
[08:10] <number10> I also got a record
[08:10] <daveake> But I did get different ones
[08:10] <daveake> Oh?
[08:10] <number10> an impresive altitude of -3272 - lol
[08:10] <daveake> #23 altitude?
[08:10] <daveake> Ah
[08:10] <daveake> Add digit
[08:10] <daveake> lol
[08:10] <Upu> claiming a programming bug as a record :)
[08:10] <number10> -32722
[08:11] <daveake> I think you need exceptionally well for a first launch
[08:11] <number10> ok well maybe I should gange it - programming bugs could encourage cheating
[08:11] Action: Upu draws number10's attention to : http://ukhas.org.uk/guides:common_coding_errors_payload_testing#negative_altitudes
[08:11] <daveake> :D
[08:11] <number10> wel, thats a lot down to help from you daveake, and everyones trcking
[08:11] <daveake> np
[08:12] <Upu> was a good day
[08:12] <Upu> we need all the trackers
[08:12] <Upu> shame I had to go but it seems I was still uploading MONDO telemetry all the way down to 2km
[08:12] <daveake> I keep wanting to do things like average GPS altitudes since last Tx, but the moment I start tinkering with that is the moment I introduce possible bugs
[08:12] <number10> I dont use the tiny gps stuff Upu
[08:13] <Upu> me neither I do it all in my own code
[08:13] <daveake> ditto

[08:13] <number10> I did mean to do a lot more testing though
[08:13] <Upu> but for the record
[08:13] <Upu> original Ava had that bug
[08:14] <daveake> :)
[08:14] <Upu> but as the GPS failed no one realised!
[08:14] <daveake> I had different ones
[08:14] <daveake> lol
[08:14] <number10> lol
[08:15] <Upu> Anyway daveake
[08:15] <Upu> I have a new toy turning up
[08:15] <daveake> oh?
[08:15] <Upu> and I need to borrow your tracker again as this is going up with 2 trackers minimum
[08:15] <Upu> I bought a GoPro Hero 2
[08:15] <daveake> :)
[08:15] <daveake> oh nice
[08:16] <daveake> I have to buy cameras today :p
[08:16] <Upu> sold all my old camera gear off
[08:16] <daveake> Well soon
[08:16] <Upu> I thought you were not launching for a while now ? :)
[08:16] <daveake> and a new 24" chute (one I only had for an hour)
[08:16] <number10> nice one Upu
[08:16] <daveake> I have to repeat yesterday -He +H2 -Sea
[08:16] <Upu> I got a FCD too
[08:17] <daveake> and go for Steve's record
[08:17] <Upu> I think you may have been close yesterday with H2
[08:17] <daveake> and prolly other thngs
[08:17] <daveake> yup
[08:17] <daveake> I reckon H2 adds 700m. More if the He isn't pure
[08:18] <daveake> Think I was 800m below Steve
[08:18] <Upu> 5% isn't it ?
[08:18] <daveake> Yeah
[08:18] <Upu> you were 2% off Steve's record
[08:18] <Upu> how much did the payload weigh ?
[08:18] <daveake> Less than 300g inc chute
[08:19] <Upu> I think within reason weight doesn't make massive difference to the over all altitude
[08:19] <daveake> http://www.flickr.com/photos/daveake/sets/72157629973059769/
[08:19] <daveake> Agreed
[08:19] <daveake> My neatest payload so far
[08:20] <Upu> very neat
[08:20] <Upu> another Trimble Lassen is sacrificed to the north sea gods
[08:20] <daveake> I could make an x-y wire cutter and mass produce them :)
[08:20] <daveake> Yeah!
[08:20] <Upu> oh it was a ball within a ball
[08:20] <Upu> very neat
[08:20] <daveake> That was the same tracker I used in the Buzz2 record flight
[08:21] <daveake> Yeah, I thought about different construction methods then came up with that
[08:21] <daveake> Worked really well
[08:21] <Upu> did you put contract details on it ?
[08:21] <Upu> contact
[08:21] <daveake> Only tricky bit is the aerial
[08:21] <daveake> No, FORGOT!
[08:21] <daveake> I had a laminated label too

[08:21] <Upu> ?
[08:22] <daveake> Me nothing
[08:22] <daveake> Just supplied tracker
[08:22] <daveake> number10 has video and pix

[08:42] <number10> maybe next time I will try seting focus infinity
[08:42] <fsphil-laptop> with that weather you wouldn't get much more detail anyway
[08:43] <fsphil-laptop> that would have looked amazing at sunset though

[08:44] <NickB_> hi all
[08:44] <navrac> morning daveake - sorry for yesterday, hope a fisherman comes to your aid.
[08:44] <NickB_> was Buzz recovered yesterday ?
[08:44] <daveake> nope
[08:44] <daveake> Too late for a boat
[08:45] <daveake> Telemetry stopped after
[08:45] <Morseman> Sorry to hear that. Any signal heard today?
[08:45] <navrac> oh...
[08:45] <daveake> Yes, we got a good signal from the coast
[08:45] <NickB_> sorry to hear dave, it was a great flight
[08:45] <daveake> Oh, today?
[08:45] <daveake> No, it stopped yesterday
[08:45] <navrac> I thought you got a couple of positions and then it went quiet for a long time
[08:45] <Morseman> Shame
[08:45] <daveake> Yeah, fun flight
[08:45] <Morseman> Good flight though
[08:45] <number10> fish and chips as well
[08:46] <navrac> as in we didnt hear from you - I thought you might have been out on a boat
[08:46] <daveake> We got to the coast, and number10 in his car and me in mine both heard the rtty
[08:46] <number10> I wonder if any of the crabbing boats out today will find it
[08:46] <daveake> So we parked up in a car park above the beach
[08:46] <navrac> I left mirc on - I'll read back and get the sdecond half of the story
[08:46] <daveake> Got out the yagi and started decoding
[08:46] <Morseman> Any news of BONZO1 yet?
[08:46] <daveake> Then saw the thing was heading east basically
[08:46] <daveake> Couldn't find any local boat companies
[08:47] <daveake> Found "The Fishing Boat" on google with a pic of some fishing boats ...
[08:47] <Morseman> Hopefully tide will bring it back in today
[08:47] <NickB_> kml file from Buzz -> http://www.2shared.com/file/PNQmbFgW/BUZZ.html
[08:47] <daveake> .... called them up "Do you hire out boats?" ...
[08:47] <daveake> .... "No, we're a a pub"
[08:47] <daveake> cheers NickB_
[08:47] <Morseman> I read that last night :-)
[08:47] <daveake> We laughed ... :p
[08:48] <daveake> So number10 called the harbourmaster at a place up the coast
[08:48] <daveake> If we'd called 30 mins earlier he had a boat in the area
[08:48] <daveake> Too late. he gave us the number of aplace to try but no answer
[08:49] <daveake> So we went back to the car park and listened again. no signa;
[08:49] <daveake> But a retired fisherman came over, curious as to what we were doing
[08:50] <daveake> We explained all and he said he'd speak to the fishermen today and tell them to look out for a bright pink ball :D
[08:50] <daveake> So, there's hope
[08:50] <fsphil-laptop> I think you need to invest in flight termination technology daveake :)
[08:50] <NickB_> hopefully no fish is sending out rtty :)

[08:59] <andrew_apex> how did the recovery go yesterday?
[09:00] <daveake> I'm still recovering today :D
[09:00] <daveake> Oh you mean the payload :D
[09:00] <andrew_apex> :P
[09:00] <daveake> Had to give up on Buzz - no boats and lost telemetry
[09:00] <number10> I havent recovered - but Anu and Cloud recovered
[09:01] <daveake> We spoke to a retired fiaherman who's putting the word out today
[09:01] <number10> not sure I am going to be able to receive Bonzo here - is there a link to prediction gonzo_ ?
[09:01] <Morseman> Interesting how it flew around the barracks at Swanton Morley
[09:01] <fsphil-laptop> Morseman, actual rtty?
[09:02] <Morseman> Actuall RTTY
[09:02] <fsphil-laptop> I think we're the only crowd who do rtty on 70cm :)
[09:02] <number10> where are you Morseman?
[09:02] <Morseman> Only a short busrt so wasn't quick enough to be able to tune onto it

[09:24] <RocketBoy> now thats uggly ballooning
[09:25] <daveake> Mornign RocketBoy. Decent drive home? Thanks very much for coming out for the launches and helping with the chase
[09:25] <fsphil-laptop> http://aprs.org/balloons/payload0.JPG
[09:25] <fsphil-laptop> wow
[09:26] <daveake> I'l be ordering another 24" chute (that one didn't last long!) and some more latex soon
[09:26] <fsphil-laptop> not sure if that's brilliant or nasty
[09:26] <Elwell> "The jury is still out as to whether a long duration mission is possile." -- I thought folks here had got really good long floats?
[09:26] <fsphil-laptop> indeed Elwell
[09:26] <RocketBoy> daveake: ah - no probs - its always a fun day - whether I launch or not
[09:26] <fsphil-laptop> navrac's flight floated for ages
[09:27] <RocketBoy> daveake: I read back though the log - so it packed up transmitting?
[09:27] <daveake> Number10's flight was a very easy recovery, excluding the females of the species ignoring clear navigation commands :D
[09:27] <daveake> Yes, eventually
[09:27] <fsphil-laptop> haha
[09:27] <number10> lol
[09:28] <RocketBoy> I was amazed at how close it landed to the shore
[09:28] <daveake> 1 mile out
[09:28] <daveake> 2 from where we parked
[09:28] <RocketBoy> the tracker prediction was way out
[09:28] <daveake> Pretty good signal from there thru the yagi
[09:28] <daveake> yup
[09:29] <daveake> It was doing near 1mph, but east not south-west
[09:29] <RocketBoy> I must see if i can mod the code and add my descent model to the tracker code
[09:29] <daveake> that'd be very good
[09:30] <daveake> I like the way that works
[09:30] <daveake> Seems a very sensible method to me
[09:30] <RocketBoy> I was expecting it to land way out to sea - otherwise I would have come along
[09:30] <daveake> :D
[09:30] <daveake> And I'd have set out earlier!
[09:31] <daveake> We'd have seen it land from the cliff
[09:31] <Upu> how close to the sea were the predictions (morning RocketBoy)

[09:33] Action: daveake remembers he has a large cylinder of something other than He in the car
[09:34] <Upu> anyway BONZO, is that a Pico or a proper balloon ?
[09:34] <daveake> pico
[09:34] <Upu> ah ok I'm probably out of range then
[09:34] <number10> is there a prediction for Bonzo?
[09:34] <daveake> pass
[09:36] <RocketBoy> andrew_apex: is the tracker code on github?
[09:37] <gonzo_> mornin
[09:37] <andrew_apex> RocketBoy: which tracker?
[09:37] <gonzo_> BONZO isn't a proper balloon! I'm hurt
[09:37] <RocketBoy> the spacenear.us tracker
[09:37] <gonzo_> but no it isnt
[09:37] <andrew_apex> ah yeah, think it should be
[09:37] <Upu> lol
[09:38] <gonzo_> just a trial of the tracker, proper balloon later (have two in the box)
[09:38] <Upu> it is somewhere RocketBoy as I've downloaded it but not sure where
[09:38] <RocketBoy> I'll go fishing
[09:38] <daveake> Go fishing near Cromer
[09:38] <fsphil-laptop> eek, looked outside. torrential rain. there goes my gloating about us getting better weather
[09:38] <gonzo_> no real predictions as I don't really have the params
[09:39] <RocketBoy> did anyone here track the mondo flight?
[09:39] <gonzo_> playing with the descent rate puts us landing NE of here, between 20 and 100km
[09:39] <fsphil-laptop> I left my radio on mondo but I don't think it decoded anything
[09:39] <fsphil-laptop> all the signals where weaker here yesterday than usual
[09:40] <RocketBoy> I brefily looked at it when it was passing about 25km - just looked strange
[09:40] <RocketBoy> the packets seemed much too short -
[09:40] <fsphil-laptop> I did see on the waterfall that each carrier was wider than it should be
[09:41] <RocketBoy> looked like each transmission may have been 2 or 3 bursts of data
[09:41] <fsphil-laptop> it was pausing during the string?
[09:41] <cuddykid> daveake: did you get it back?!
[09:41] <fsphil-laptop> I've seen that before, but I can't remember if it was mondo that did it
[09:41] <RocketBoy> each burst seemed to bend toward the lower frequency
[09:42] <fsphil-laptop> yea, that's an ntx2 thing
[09:42] <fsphil-laptop> er
[09:42] <daveake> cuddykid no
[09:42] <fsphil-laptop> they where not using an ntx2, but I've seen it do the same thing
[09:42] <RocketBoy> it wasn't an ntx2
[09:42] <cuddykid> daveake: ahh no :(
[09:42] <RocketBoy> could just be power supply sag on transmit load
[09:42] <daveake> It wasn't meant to float (in either sense)
[09:43] <fsphil-laptop> it's with the mermaids now. they've got so many payloads, they just need a tracking radio and they can launch their own
[09:43] <daveake> sag seems likely
[09:43] <RocketBoy> yeah - i'll reply to his email
[09:44] <fsphil-laptop> time for TOAST

[09:54] <Bob_G8NSV> fixed the 78 mhz osc fault, set that up but problem with VCO, still off frequency and has a lot of noise
[09:54] <Morseman> Morning Bob_G8NSV
[09:54] <Bob_G8NSV> morning morseman
[09:54] <Bob_G8NSV> just putting my yagi up ready for Bonzo launch
[09:55] <Morseman> I noticed ANU seemed to pause during each transmission yesterday - someone said poss a buffer problem?
[09:56] <Morseman> Also, how do I get an older copy of DL-FLDigi than 3.20.29 so I can set for different lat/long strings please?
[09:57] <Morseman> I was getting good copy from ANU but FLdigi couldnt cope with the way the lat/long was set up
[09:59] <number10> the pause is sort of intentional Morseman: I had not got round to doing the RTTY with an interrupt - so the pause is when the temperature sensors are read
[09:59] <Morseman> Ah, thanks for explanation number10
[10:00] <Bob_G8NSV> yeah my payload has to pause whilst I read the GPS data, only 2 seconds butthe tx stays on
[10:00] <Morseman> I still need to find an older copy of FLDigi as people were telling me to change things that my copies didn't have options for. Or, I couldn't find them anyway
[10:01] <number10> what options do you want to change?
[10:02] <Morseman> Your TX was NNNN.NNN and FLdigi (v3.21.38 and v3.20.29) seem to expect NN.NNN
[10:02] <Morseman> someone suggested changing the 'APRS packet' setting but couldn't find that option in eitgher version yesterday
[10:03] <number10> I used 3.20.29 here to test it
[10:04] <number10> I cant remember having to change anything
[10:04] <number10> on fldigi settings
[10:05] <RocketBoy> actaually a pause is no bad thing - if a start/stop bit gets corrupted the receiver looses character sync
[10:05] <RocketBoy> it can re-sync when it gets to the pause
[10:06] <Morseman> I was getting good copy but the distance/bearing were way off - by hundreds of km and set bearing way off actual in 3.21.38
[10:06] <Morseman> and seemed same in 3.20.29 which was where the suggestion about 'APRS packet' setting came up
[10:07] <number10> RocketBoy: thankls again for your help yesterday :)
[10:07] <number10> -l
[10:07] <RocketBoy> np
[10:07] <RocketBoy> it was good to see you
[10:09] <number10> and you.. Ros enjyed meeting everyone - now she can put faces to names

[10:09] <number10> bug
[10:11] <jonsowman> there are much worse bugs, don't worry

[10:11] <priyesh> *cough* accidental cutdown *cough*
[10:11] <jonsowman> haha
[10:11] <number10> :)
[10:11] <Morseman> Just checked both versions I have loaded and can't find any way to set how either version decodes the lat long with NNNN.NNN format so I guess was an earlier version?
[10:11] <jonsowman> i was very obliquely referring to that
[10:11] <Upu> lol
[10:11] <jonsowman> not subtley enough, it seems
[10:11] <priyesh> oh.. i went for the subtle approach
[10:12] <andrew_apex> I was thinking more the 'invalid uplink commands can lock up the processor' bit :P
[10:12] <Morseman> subtle as a flying brick?
[10:12] <RocketBoy> oooo forgot to ask - where is the SHARP cutdown test video?
[10:12] <priyesh> andrew_apex: ah - thanks for reminding me!

[10:14] <Morseman> Does anyone have a link to earlier version of DL-FLDigi than 3.20.29 please?
[10:14] <RocketBoy> :-)

[10:32] <fsphil-laptop> it's just awful out there
[10:32] <fsphil-laptop> some payloads use the nmea-style coordinates (ddmm.mmmm) and others use just straight decimal (dd.dddd)
[10:33] <fsphil-laptop> old dl-fldigi only understands the decimal versions
[10:33] <Morseman> Thanks fsphil-laptop now just need to transfer to radio PC
[10:33] <fsphil-laptop> and mis-calculates the distance when it tries to work with the nmea-style points
[10:34] <Bob_G8NSV> had to put more bungees rond the pole wind was blowing it everywhere
[10:34] <Morseman> fsphil-laptop that's waht I was getting with 3.21.38
[10:34] <fsphil-laptop> eek
[10:34] <Bob_G8NSV> its a little 7 ele I built for portable use but not used it away from home yet
[10:35] <Morseman> It showed the laty/long as NNNN.NNNN but didn't calc dist/bearing and I didn't appear to be uploading to tracjker either
[10:35] <fsphil-laptop> there's been lots of issues with the tracker not displaying callsigns
[10:35] Action: Morseman has fat finger syndrome
[10:36] <fsphil-laptop> it's difficult actually as the spacenear.us page only refreshes every few seconds, so it only sees the callsigns that have uploaded to that point
[10:36] <Morseman> Got to go shopping in Meadowhell so will have to get going...
[10:36] <fsphil-laptop> I think the test tracker solves that by streaming the data
[10:36] <Morseman> and that *wasn't* a typo!!!
[10:36] <fsphil-laptop> wrap well Morseman :)
[10:37] <fsphil-laptop> it's nasty out there
[10:37] <Morseman> Not too bad round here - cloudy and a bit of a breeze but no rain yet
[10:37] <fsphil-laptop> ah - not too bad then
[10:38] <fsphil-laptop> even my dog won't go out, and he usually doesn't care

[11:14] <Bob_G8NSV> has anyone looked at a viable method to produce ones own hydrogen?
[11:14] <gonzo-mob> team bonzo on site
[11:15] <fsphil-laptop> I tried to produce some H2 using electrolyses. It worked but was soooo sloooow
[11:15] <Morseman> Something a bit like RTTY on 434.651 + 1000Hz
[11:15] <fsphil-laptop> there are quicker methods but I'm not good at chemistry
[11:15] <daveake> Some videos on YT of people using household chemicals
[11:15] <daveake> Some don't go so well
[11:16] <Bob_G8NSV> yes I was looking at designs for those silly things people put on cars and modifying the design to just get the one desired gas

[11:17] <Bob_G8NSV> aluminium foil and lye produces more but also loads of steam you dont want in the envelope, so you would need to dry the gas

[11:17] <Bob_G8NSV> test I guess
[11:18] Action: LazyLeopard figures the Astra folk are testing something
[11:19] <Bob_G8NSV> a decent electrolysis system may be able to produce enough for pico launches?

[11:19] <fsphil-laptop> that was my thinking
[11:20] <fsphil-laptop> and probably could be done, I'm just not very good at that kind of thing :)
[11:20] <fsphil-laptop> I was told I was using too high a voltage
[11:21] <Bob_G8NSV> it may need something like a mains powered PSU, ok if you launch from home, or may work from a generator. either way you would want to run it outdoors!!
[11:21] <fsphil-laptop> I was using a solar array
[11:21] <fsphil-laptop> which puts out about 70v DC
[11:21] <Bob_G8NSV> you need a certain voltage per cell from what ive read. mind you its all on these run a car for nothing articals
[11:22] <navrac> I was looking at those in car generators - but they actually didnt generate that much - or that quickly either.
[11:23] <Bob_G8NSV> thats why they dont work!!!

[11:23] <Bob_G8NSV> I have seen photos of bigger browns gas generators used to power small brazing/welding torches
[11:24] <navrac> I need 0.8m3 of helium or hydrogen and i thought about generating the hydrogen rather than buy two disposable d50 cylinders or wasting half of a pt10
[11:24] <Bob_G8NSV> very high temperature as its the perfect mix of hydrogen and oxygen
[11:24] <Clive-G7SVI> we have sunshine :-) That should dry G0NZO and the team out a bit

[11:25] <Bob_G8NSV> electrolysis seems to be all about the surface area of the plates, and you need an electrolyte in the water to kick things off
[11:26] <fsphil-laptop> yea, I didn't have an electrolyte
[11:26] <fsphil-laptop> which is why I think it was going so slowly
[11:26] <Bob_G8NSV> It should be feasible to do for a pico surely. Fill as its produced, storage may be a bad idea

[11:50] <navrac> bob_g8nsv you sound like you are experimenting with the same things i am
[11:51] <navrac> I'm making a 8mm wide tip for my temperature controlled iron - the mrs didnt like me experimenting with her iron and i couldnt get the temp right
[11:52] <navrac> or enough pressure either to maske a really good seal
[11:52] <Bob_G8NSV> I have a naff old travel iron kicking about somewhere, might try and frig the thermoststat
[11:53] <navrac> funnily enough so have I - but to get a really good seal with heptax it seems to need a good bit of pressure.
[11:53] <Bob_G8NSV> yes looks like solars are the thing people are playing with. or is it a home made gas envelope?
[11:54] <Bob_G8NSV> I have been playing with bin liners
[11:54] <navrac> I'm going for a pico+ superpressure out of heptax at the moment - 1.6m tetroon shape as its easier to seal

[11:55] <Bob_G8NSV> aha. I was thinking of the possibility of home made gas envelopes. where did you get the material?
[11:56] <Bob_G8NSV> tetroons are simple but much less volume than a trad shape. so much easier to make though
[11:56] <navrac> imported from the states. I got a sample sent over which ive been experimenting with and im expecting the main roll to arrive next week
[11:56] <Bob_G8NSV> some real long range floaters then!!
[11:56] <navrac> well i was working on 'the less seals the better' for my first one. Then go for a 3m traditional round one
[11:57] <navrac> I must sqay when you get it right the seal is stronger than the material
[11:57] <Bob_G8NSV> 2 layers thick so yes that would be right
[11:57] <navrac> well I want a round the world at least once floater
[11:57] <Bob_G8NSV> my experiments have never torn the weld
[11:58] <navrac> likewise. ther heptax is pretty strong - similar to foil balloons in weight but seem to be a lot stronger
[11:59] <Bob_G8NSV> solars need the lightest envelope possible, there is so little lift from small ones
[11:59] <navrac> and they drop at night. Hence working on superpressure
[11:59] <Bob_G8NSV> something in the pico size range will be less than 100g of useable lift
[11:59] <Bob_G8NSV> enough tho
[12:00] <navrac> a 1m tetroon gives 180g of free vlift. My payload is only 38g
[12:01] <Bob_G8NSV> my payload should be similar, well under
[12:01] <Bob_G8NSV> 100. Oh by the way thanks for the software code you shared with me, it helped a lot and is the basis of my payload code
[12:01] <navrac> I havent got the calcs for the 1.6m tetroon to hand but it gave several hundred grams of free vlift so should float at a decent hight - about 10km - which will help with the range
[12:02] <Bob_G8NSV> changed to work with an nmea gps
[12:02] <griffonbot> Received email: "Re: [UKHAS] MONDO-8 launch ...."
[12:02] <navrac> no prob - most of the code came from jcoxon to start with
[12:02] <navrac> and he got parts of it from someone else etc
[12:03] <Bob_G8NSV> yes true open source!!!
[12:03] <navrac> Well its all about sharing data in this hobby.
[12:03] <Bob_G8NSV> was fun doing the payload code, just got to do the flight ready prototype, this one is still on a breadboard
[12:04] <Bob_G8NSV> code will be same tho!!
[12:04] <navrac> yep, i would do my payloads on pcb - did ozzie1 on a pcb made in the kitchen, ozzie2 got sent to the garage for pcb making after some suspicious brown stains on the worktops
[12:05] <navrac> I'm too impatient to send my layouts of to sseed studio or similar

[12:06] <navrac> I have a convenient tree for payload hanging. I do love the homebrew/heath robinson part of this hobby
[12:06] <Bob_G8NSV> 12H will be enough sun will be down by then and it will be bye bye
[12:07] <navrac> thats quite achievable with a pair of AAA's
[12:07] <Bob_G8NSV> so do I its like ham radio in the good old days where people actually make things
[12:07] <navrac> ozzie2 could run straight 20 hours off 2xAAA before using the solar.
[12:08] <navrac> with the solar it managed two nights & 3 days on the tree
[12:08] <Bob_G8NSV> Yes I should get enough time. my gps uses a bit more power, but the throw away price is worth it
[12:09] <navrac> That is the downside of pico's - the float means you rarely get the payload back
[12:09] <Bob_G8NSV> solars the same
[12:10] <Bob_G8NSV> the lower height does allow cheaper GPS modules tho
[12:10] <navrac> the problem with superpressure is that you dont get the payload bvack and you still need to pay for a biggish bottle of helium. So worst of both worlds
[12:10] <fsphil-laptop> you can't get much cheaper than the ublox 6 now
[12:11] <navrac> well upus ublox qarent all that pricey
[12:11] <fsphil-laptop> or lighter
[12:11] <Bob_G8NSV> less than a fiver
[12:11] <Bob_G8NSV> and 3g
[12:11] <Bob_G8NSV> fiddly to solder tho!!
[12:11] <navrac> ok thats cheap - an ebay bulk buy?
[12:13] <Bob_G8NSV> yep will get a few more, no good for proper high altitude tho, no flight mode will stop around 18Km most likely
[12:13] <Bob_G8NSV> and not as sensitive rx

[13:13] <G0MJW> Needs toget a bit higher than sea level for me to hear it
[13:14] <Rob_m0dts> not that i can hear it, just noticed on tracker thats all.
[13:14] <andrew_apex> i had it, then it went :(
[13:14] <Bob_G8NSV> lot of fading here
[13:14] <daveake_> just stopped
[13:15] <Bob_G8NSV> no still there

[13:19] <Bob_G8NSV> pico
[13:19] <daveake_> Since it faded, I did see 2 very faint lines briefly. Now nothing at all
[13:19] <daveake_> Assume some hill in the way
[13:19] <Bob_G8NSV> well within hurn circuit not good
[13:20] <Bob_G8NSV> protected airspace
[13:20] <r2x0t> just next to the airport
[13:20] <Bob_G8NSV> dont know alt wants to be well away from 1000ft
[13:20] <r2x0t> it went down?
[13:20] <priyesh> alt seems to have droppec

[13:30] <andrew_apex> so sounds like its now 2x foil
[13:30] <navrac> might have lost one hence the low altitude

[13:47] <jcoxon> it can be manually added if needs be
[13:48] <fsphil-laptop> if you're on the old dl-fldigi, goto the payload config and check the callsign is correct

[13:50] <priyesh> i put the last one into transition
[13:50] <priyesh> seems to have worked
[13:50] <Matt_soton> the strings are unix terminated rather then windows terminated
[13:51] <fsphil-laptop> that's right, they should be \n rather than \r or \n\r
[13:51] <andrew_apex> it made it over all that water then :D
[13:51] <Matt_soton> i think i \n\r , but then it doesnt matter after the \n
[13:51] <andrew_apex> so its inside the new forest national park
[13:51] <fsphil-laptop> yea
[13:51] <fsphil-laptop> the current code also treats \r as \n, so it should handle any style
[13:52] <fsphil-laptop> but the last beta gets confused by an \r
[13:52] <fsphil-laptop> if it comes first

[15:20] <number10> its not me jonsowman
[15:21] <jonsowman> oh sorry
[15:21] <number10> Morseman: has a problem that telemetry does not populate the lat lon windows at the top of fldigi
[15:21] <jonsowman> oh, that
[15:21] <jonsowman> yes, i'm unsure why it does that sometimes
[15:21] <jonsowman> though i'm not an fldigi person
[15:22] <number10> I think it just sometimes need to be restarted and try autoconfigure a few times
[15:22] <number10> did you do exam today jonsowman ?
[15:23] <jonsowman> yep
[15:23] <number10> OK?

[17:29] <jonsowman> *is
[17:30] <fsphil-laptop> yea
[17:31] <jonsowman> 10mW from an isotropic antenna
[17:31] <jonsowman> so anything more than 0dBi is disallowed

[17:32] <fsphil-laptop> they specify it against eirp
[17:33] <fsphil-laptop> against == separate from
[17:34] <Bob_G8NSV> just eating but would guess a qfh is close to a true isotropic radiator
[17:34] <Bob_G8NSV> so less than a dipole
[17:34] <jonsowman> i think i'm right in saying 10mW into an isotropic antenna is the limit
[17:35] <jonsowman> so any gain over isotropic is technically not allowed

[17:58] <Bob_G8NSV> try that one
[17:58] <nigelvh> There we go.
[17:58] <fsphil-laptop> that's it
[17:59] <nigelvh> It appears to be a good bit taller than one I've built
[17:59] <Bob_G8NSV> it wouldnt take much bashing around without some sort of reinforcement
[17:59] <Bob_G8NSV> 220mm tall
[18:00] <nigelvh> Though, that's one of the design options. You can choose taller or fatter. I built mine for 137MHz and it's a good bit wider.
[18:01] <Bob_G8NSV> I have a 137MHz one in the roof now, built fro some scrap heliax
[18:01] <Bob_G8NSV> I took the defaults for this one
[18:01] <nigelvh> Sounds reasonable. As long as it tunes up, then it's an antenna of some sort.

[18:02] <Bob_G8NSV> you can alter the ratios and stuff but not sure quite what the effect is
[18:02] <nigelvh> I think it shapes the sphere a bit, either a little flatter, or a little taller.
[18:03] <Bob_G8NSV> I think the default is meant to be close to a true sphere
[18:03] <Bob_G8NSV> ideal for a payload
[18:04] <nigelvh> I would think you'd want it closer to a taller sphere.
[18:04] <nigelvh> Or rather a reflector so you don't lose half of everything towards space.
[18:05] <griffonbot> Received email: Steve Aerospace "Re: [UKHAS] Re: Possible ANU / BUZZ / CLOUD Launch - 5/5/2012"
[18:05] <Bob_G8NSV> that would give "gain" up and down, the benifit should be from a true sphere, no fading and chopping when it spins
[18:05] <fsphil-laptop> spherical would be good after burst where the payload may be tumbling
[18:06] <Bob_G8NSV> thats the point whatever the orientation the signal level should be the same
[18:06] <nigelvh> Yes, but from all the video I've seen, there may be some bumpyness, but for the most part the payload is under gravity.
[18:06] <fsphil-laptop> yea the chute usually keeps it upright
[18:07] <fsphil-laptop> well the cord keeps it upright at first
[18:07] <fsphil-laptop> the chute just sits there and flops about
[18:07] <nigelvh> My point is that a half sphere would probably cover things even with the bumping about.
[18:07] <fsphil-laptop> some of the video I've seen does have payload spinning upside down for a few seconds
[18:07] <Bob_G8NSV> a flattened sphere would give "gain" towards the horizon but a true sphere probably the best all round
[18:08] <fsphil-laptop> it would be interesting to fly both
[18:08] <nigelvh> Indeed.
[18:08] <Bob_G8NSV> the only worry would be surviveability on impact

[18:44] <fsphil-laptop> well you did say quick :)
[18:45] <Bob_G8NSV> made about 10-12 miles before landing
[18:45] <Upu> didn't go very high
[18:45] <Upu> came down
[18:45] <daveake> it was
[18:45] <Upu> was recovered

[18:53] <Lunar_Lander_> did it reach the stratosphere?
[18:53] <Lunar_Lander_> as was planned?
[18:53] <fsphil-laptop> what was the delay after launch and the cheering?
[18:53] <Lunar_Lander_> ascent maybe?

[19:14] <fsphil-laptop> they publish datasheets I believe

[19:14] <nosebleedkt> prons and cons
[19:15] <fsphil-laptop> pro: they're not prone to bursting
[19:15] <fsphil-laptop> also a con
[19:15] <nosebleedkt> what i should avoid..
[19:15] <fsphil-laptop> don't underfill it
[19:15] <nosebleedkt> so overfill it?
[19:16] <fsphil-laptop> try to keep the ascent rate over 5m/s
[19:16] <fsphil-laptop> that should be enough
[19:16] <nosebleedkt> i want to reach about 35km. Should I trust Randomskk's burst calculator?
[19:16] <daveake> If it's a photo payload, use a 1000 or 1200 and aim for 5m/s or more. You'll be fine
[19:16] <nosebleedkt> I have 1600g
[19:16] <daveake> If it's a light payload and a 1600, be careful
[19:16] <nosebleedkt> 100g
[19:16] <nosebleedkt> 1000g
[19:16] <nosebleedkt> 1kg :)
[19:17] <daveake> Aim for 5.5m/s
[19:17] <daveake> Upu and I went for 5.5-6 (I forget exactly - Upu did the filling) and it got pretty high
[19:18] <nosebleedkt> well
[19:18] <Upu> I put all of it in
[19:18] <nosebleedkt> look
[19:18] <nosebleedkt> go to http://www.cusf.co.uk/calc/
[19:18] <nosebleedkt> give 1000 for payload 1600 for hw balloon and 35000 for alt
[19:18] <daveake> I have, once or twice
[19:18] <nosebleedkt> Ascent Rate: 6.65 m/s
[19:19] <daveake> Yes, it wants to go higher. 6.65 is quite fast
[19:19] <nosebleedkt> so ?
[19:20] <nosebleedkt> i will have problem?
[19:20] <Upu> just remember the balloon isn't the most aerodynamic thing
[19:20] <Upu> if I was launching something expensive I'd be aiming for 6m/s
[19:20] <Upu> +
[19:20] <Upu> I've seen 8m/s but don't expect to get an altitude record
[19:20] TimZaman (~chatzilla@82-169-207-126.ip.telfort.nl) joined #highaltitude.
[19:20] <daveake> No,just do what we said. Aim for 5.5 or higher. You can't go a lot higher without a lot more gas as the balloon gets bigger and slows it down
[19:20] <TimZaman> buon giorno
[19:21] <Randomskk> nosebleedkt: specify ascent rate instead of burst
[19:21] <Randomskk> 1000g payload and 1600g balloon
[19:21] <Randomskk> ascent rate 5
[19:21] <TimZaman> c++ question anyone?
[19:21] <Randomskk> gives burst 36.6k, ascent 5.4m/s
[19:21] <nosebleedkt> ok so, 1kg payload, 1600 hw balloon and 6 m/s
[19:21] <nosebleedkt> Randomskk isnt 36.6 too much ?
[19:22] <daveake> why?
[19:22] <nosebleedkt> dunno man im afraid :)
[19:22] <Randomskk> no, that's fine
[19:22] <daveake> of what?
[19:22] <TimZaman> congratulations to rocketboy for the reocrd
[19:22] <nosebleedkt> im afraid of heights, lol
[19:22] <TimZaman> record
[19:23] <nosebleedkt> so for 5.4m/s
[19:23] <nosebleedkt> i get

[19:23] <nosebleedkt> Time to Burst: 101 min Neck Lift: 2697 g
[19:23] <Randomskk> yes go for 5
[19:23] <Randomskk> it'l end up at 5.4
[19:23] <Lunar_Lander_> hello TimZaman ! how are you?

[19:24] <nosebleedkt> so can anyone explain to me this balloon configuration?
[19:25] TimZaman (~chatzilla@82-169-207-126.ip.telfort.nl) left irc: Client Quit
[19:26] <nosebleedkt> I really need someone to explain me dudes!
[19:26] <Randomskk> the launch config?
[19:26] <Randomskk> it's not hard
[19:26] <nosebleedkt> yes
[19:26] <Randomskk> type in payload mass, balloon size, tell it something like 5m/s ascent rate (it doesn't really matter much, that's about good)
[19:26] <Randomskk> then it will tell you what to do
[19:26] <nosebleedkt> Randomskk, no
[19:26] <Randomskk> how much helium to put in / how much neck lift to go for
[19:26] <nosebleedkt> i mean the physics
[19:26] <nosebleedkt> :)
[19:27] <Randomskk> also fairly straightforward
[19:27] <Randomskk> fixed volume at ground pressure and temperature of helium
[19:27] <Randomskk> inside a roughly spherical balloon
[19:27] <Randomskk> so we can work out launch diameter
[19:27] <Randomskk> which gives the ascent rate by a somewhat simplified air resistance
[19:27] <Randomskk> we know what diameter the balloon will burst at
[19:28] <Randomskk> and the atmospheric density
[19:28] <Randomskk> so can calculate what altitude will cause the helium to expand so much the balloon bursts
[19:28] <nosebleedkt> thats my balloon config: http://imagebin.org/211445
[19:28] <Randomskk> and given the ascent rate, the time it takes to burst
[19:28] <Randomskk> looks fine
[19:29] <nosebleedkt> what would be the difference if i had the other UK type balloon?
[19:29] <Randomskk> bursts at a different altitude
[19:29] <Randomskk> uh, diameter.
[19:29] <Randomskk> same thing here
[19:29] <Randomskk> the two balloons have different burst diameters
[19:29] <nosebleedkt> yes, why is that?
[19:29] <nosebleedkt> the material of the balloon?
[19:29] <Randomskk> different manufacture. thicker/different latex.
[19:29] <nosebleedkt> ok
[19:29] <Lunar_Lander_> fluctuations in manufacture year
[19:29] <Lunar_Lander_> yea
[19:30] <nosebleedkt> ok
[19:30] <nosebleedkt> i understand all but the neck lift
[19:30] <Lunar_Lander_> yea that is like I was told the max the balloon may carry before ripping
[19:30] <Randomskk> uhm not quite
[19:31] <Randomskk> the neck lift is how much force (in kilograms on earth surface gravity) the balloon will pull up with when it has the right amount of helium in
[19:31] <Randomskk> in other words if you attach scales to the balloon neck while filling, they'll read that value (minus the weight of any suspended filling kit)
[19:31] <Randomskk> at that point you're ready to go
[19:31] <acg> 75 years since the Hindenburg disaster FYI
[19:32] <nosebleedkt> ehm, i cant really say that i got it
[19:32] Hiena (~boreger@81.93.195.181.datatrans.hu) joined #highaltitude.
[19:32] <Randomskk> neck lift?
[19:32] <nosebleedkt> i will need the neck lift information when I will fill the balloon?
[19:32] <Randomskk> yea
[19:32] <Randomskk> that's how most people fill
[19:32] <nosebleedkt> oh
[19:32] <nosebleedkt> lol
[19:33] <Randomskk> for instance, if you prepare a ballast mass of the same amount -- e.g. 2.3 litres of water -- and hang this off the balloon while filling
[19:33] <nosebleedkt> let me find the greek phrase of it
[19:33] <Randomskk> then when you are filled correctly it will just be neutrally bouyant
[19:33] <nosebleedkt> Randomskk, sorry i dont understand you
[19:34] <nosebleedkt> really sorry
[19:34] <Randomskk> so as you fill the balloon
[19:34] <Randomskk> you put more and more gas into it
[19:34] <Randomskk> the more gas that goes in, the stronger the balloon will pull upwards
[19:34] <nosebleedkt> yes
[19:34] <Randomskk> at first, it doesn't pull up at all -- there's not even enough gas to lift the balloon itself
[19:34] <nosebleedkt> ok
[19:34] <Randomskk> then eventually there's enough gas to lift the balloon material up, and as you add more and more, it pulls up harder and harder
[19:34] <nosebleedkt> nice
[19:34] <Randomskk> you need it to have enough pull to lift your payload up, and still have some left over to actually pull up
[19:35] <Randomskk> the "neck lift" number is how much pull it should have before you attach your payload, so you can use that number to work out when you've put enough gas in
[19:35] <Randomskk> as that number is 2.3kg for you, one way to check would be to attach some scales to the balloon neck while you fill
[19:35] <Randomskk> once the balloon starts pulling up, it will register on the scales
[19:35] <Randomskk> and when they read 2.3kg, it is filled correctly
[19:35] <nosebleedkt> what scales man?
[19:35] <Randomskk> (but, if you have 300g of filling kit attached, like your hose and pipe, you want it to read 2kg)
[19:36] <Randomskk> scales, they measure weight
[19:36] <Randomskk> http://image.made-in-china.com/4f0j00AUPTrugnJaDw/Digital-Fish-Scale.jpg maybe

[19:36] <Randomskk> the other way -- if you don't have any scales -- is to just prepare a 'ballast'
[19:37] <nosebleedkt> wait
[19:37] <Randomskk> so you take 2.3kg of something (like water, where you'd need 2.3 litres, easily measured in bottles)
[19:37] <nosebleedkt> lets go to the device thing
[19:37] <nosebleedkt> is it expensive?
[19:37] <Randomskk> not usually. they should be pretty common.
[19:38] <nosebleedkt> and what should I attach to the hook ?
[19:38] <Randomskk> the balloon. you hold the other end down, like to the ground
[19:38] <Randomskk> the other way might be easier for you if you don't have or haven't used scales
[19:39] <Randomskk> you just need two bottles of water in a bag
[19:39] <Randomskk> and attach them to the balloon
[19:39] <Randomskk> then when it's filled right, the balloon will just float -- it won't move up or down
[19:39] <Randomskk> (with not enough gas, the bottles pull the balloon down)
[19:39] <nosebleedkt> ah nice
[19:39] <nosebleedkt> now i got u
[19:39] <nosebleedkt> the bottles should be 2.3kg?
[19:39] <Randomskk> ish
[19:39] <Randomskk> yes
[19:39] <Randomskk> which is 2.3 litres of water
[19:40] <nosebleedkt> 2.3lts
[19:40] <nosebleedkt> ok
[19:40] <nosebleedkt> and when the balloon gets the nalance
[19:40] <nosebleedkt> balance*
[19:40] <nosebleedkt> means its ready
[19:40] <nosebleedkt> to lift both itself and my payload
[19:40] <nosebleedkt> right?
[19:40] <Randomskk> yes
[19:40] <nosebleedkt> oh
[19:40] <nosebleedkt> man
[19:40] <nosebleedkt> thats easy
[19:41] <Randomskk> yup
[19:41] <nosebleedkt> so i need to find something that weights 2317g
[19:41] <nosebleedkt> and attach it to the balloon
[19:41] <Randomskk> yes. like 2.3 litres of water.
[19:42] <Randomskk> which is two large bottles and half a small bottle
[19:42] <nosebleedkt> yes, you propose me that bottles because its easy to find, right?
[19:42] <Randomskk> yes
[19:42] jdtanner (~Adium@host86-155-35-20.range86-155.btcentralplus.com) joined #highaltitude.
[19:43] <nosebleedkt> cool
[19:43] <nosebleedkt> i think i understood everything
[19:43] <nosebleedkt> and if i keep the balloon in the balance mode
[19:43] <Randomskk> cool
[19:43] <nosebleedkt> it will stay like that all the time?
[19:44] <Randomskk> no. once you remove the weight, it will want to go up, and when you attach your payload, it will still want to go up a bit
[19:44] <Randomskk> then when you do release it, it'l go up.
[19:44] <nosebleedkt> I mean if I already lift it with my hands at an alt of 1.5m
[19:44] <nosebleedkt> it will stay on air
[19:44] <nosebleedkt> ?
[19:45] <nosebleedkt> at that height?
[19:45] <Randomskk> yes
[19:45] <nosebleedkt> if you get me, lol :)
[19:45] <nosebleedkt> oh lol
[19:45] <Randomskk> while the weight is attached.
[19:45] <nosebleedkt> magic
[19:45] <Randomskk> I mean, don't let go -- it could drift slowly
[19:45] <Randomskk> but roughly speaking yes
[19:46] <nosebleedkt> then i remove the bottles
[19:46] <nosebleedkt> and put the payload
[19:46] <nosebleedkt> and byebye
[19:46] <Randomskk> yes
[19:46] <nosebleedkt> lol
[19:46] <nosebleedkt> funny
[19:46] <nosebleedkt> will be
[19:46] <nosebleedkt> that my cat at work

[19:46] <Randomskk> try not to send the cat up :P
[19:47] <nosebleedkt> lol
[19:47] <nosebleedkt> i bet she isnt more than 1kg
[19:47] <nosebleedkt> so i can send her :)
[19:47] <fsphil-laptop> brave meow world
[19:47] <jonsowman> very good
[19:47] <nosebleedkt> ok now i know the balloon filling theory
[19:47] <nosebleedkt> ill go proud at work
[19:47] <nosebleedkt> :P
[19:48] <fsphil-laptop> the first launch is always the worst
[19:48] <fsphil-laptop> until the second one
[19:48] <nosebleedkt> lol
[19:48] <fsphil-laptop> but it gets easier after that
[19:48] <nosebleedkt> so should i keep this configuration and never change it?
[19:50] <nosebleedkt> no naswer
[19:50] <nosebleedkt> lol
[19:51] <fsphil-laptop> up to you
[19:52] <nosebleedkt> e?
[19:56] <nosebleedkt> anyway
[19:56] <nosebleedkt> i got the info i wanted

[20:13] <benoxley> been in my own little world for a few hours, trying to get my head around the theory of spoked wheels
[20:13] <Lunar_Lander_> you're welcome
[20:14] <Lunar_Lander_> yeah
[20:14] <Lunar_Lander_> why do they walk into that diamond shaped gate?
[20:14] <Lunar_Lander_> do you have an idea?
[20:15] <benoxley> are you talking about rimless spoked wheels?

[20:18] <benoxley> where is a spoked wheel?
[20:19] <Lunar_Lander_> ah there is none, but that white diamond shaped door
[20:20] <benoxley> oh
[20:20] <benoxley> right, serves me right not reading the bit of conversation previous to my entry :P
[20:21] <Lunar_Lander_> yea
[20:21] <Lunar_Lander_> the song is about nuclear war says the comments

[21:11] <eroomde> seen the blog post?
[21:11] <Upu> yup seen the videos
[21:11] <Upu> most impressive
[21:11] <eroomde> i love the launch tlwer one

[21:11] <Upu> yeah

[21:12] <eroomde> thats far from the worst of it
[21:12] <Upu> though in fairness that was my response when it blew my speakers up

[21:13] <eroomde> can see why you want 300m
[21:15] <Upu> right dog walk bbs
[21:20] <gonzo_> eve
[21:22] <eroomde> yo
[21:22] <gonzo_> quick review of what's left of the bonzo balloons. Recon at least one of them burst around the seam. Recon overinflation was the cause.
[21:26] <Randomskk> eroomde: next time, a SPOT tracker :P
[21:27] <eroomde> Randomskk: i think so yes
[21:27] <eroomde> or something
[21:27] <eroomde> wspr mode looks interesting
[21:28] <fsphil-laptop> would have to be a modified wspr, as it has a low resolution coordinate system
[21:29] <eroomde> yes indeed
[21:29] <eroomde> just gps
[21:29] <eroomde> not locator bollocks
[21:29] <fsphil-laptop> yea
[21:31] <fsphil-laptop> it transmits a four digit thing, which would tell you if it landed in north or south scotland :)
[21:31] <fsphil-laptop> spot might be easier

[22:04] <eroomde> spot is a bit orientation intolerant arent they?
[22:04] <eroomde> seems a bit risky for something thatd have to deploy out of a rocket
[22:05] <nibbler> the spot has a panel antenna. (like you find in most gpses)

[22:05] <Randomskk> :P
[22:05] <eroomde> you mean patch?
[22:06] <eroomde> yes thats a solution i guess
[22:06] <nibbler> patch, yeah.
[22:06] <eroomde> so 12 spots for a 3 stage rocket
