[07:15] <number10> hows it going?
[07:16] <NigelMoby> All good, and you?
[07:16] <number10> ok but at work :( never mind
[07:16] <number10> when are you going to do the foil balloons
[07:17] <NigelMoby> Should be Saturday, forecast rain atm though

[07:26] <NigelMoby> Yup, on ebay, £6.95 each
[07:26] <rjharrison> zMORING ALL
[07:26] <NigelMoby> Morning Rob
[07:26] <rjharrison> getting the kids ready for holiday clubs etc ..
[07:27] <rjharrison> NigelMoby you up tomorrow
[07:27] <rjharrison> opps w/e
[07:27] <NigelMoby> Yup, rain or shine those balloons are going up lol
[07:27] <rjharrison> Hey natrium42 thanks for the icon. Made me lol
[07:27] <rjharrison> cool
[07:27] <rjharrison> I'll see if i can track from here
[07:28] <rjharrison> is it set sat/sun?
[07:28] <NigelMoby> Pretty sure it'll be sat, sun looks like worse chance for rain.
[07:29] <number10> I take it you are not going for a launch in the beacons then NigelMoby
[07:29] <NigelMoby> Still possible if predictions put a local launch over the cities

[07:50] <number10> does anyone have any ideas of thinks to try to get fldigi to decode. I have two PCs connected one plaing Xaben recording the other fldigi HAB mode and I can see the audio tones on the waterfall but the decode is wrong
[07:51] <number10> I presume that the number of bits and stop bits correct as in hab mode
[07:51] <fsphil> how wrong?
[07:51] <fsphil> (did you select xaben payload, and press autoconfigure?)
[07:51] <number10> shows not text chracters
[07:51] <number10> OK i'll chech that again tonight fsphil
[07:52] <fsphil> hab mode only means it uploads data and gives you the funky hab data at the top :)
[07:52] <fsphil> the rtty mode used can vary between payloads
[07:53] <number10> OK I'll check the auto configure - I had the thing working at the weeken - I presume that not everyone is using the same setup as far as number of bits and stop bits etc
[07:53] <fsphil> indeed
[07:53] <fsphil> autoconfigure should take care of all that
[07:54] <number10> thanks fsphil I'll have another play tonight and see what the different settings were used for each baloon
[07:55] <number10> aparently someone here knows someone who used to be able to decode short bursts by ear
[07:55] <fsphil> I can usually tell when my payload is transmitting images vs. text
[07:55] <fsphil> but I doubt anyone could do rtty by ear ;)
[07:56] <NigelMoby> :0
[07:56] <daveake> Inspector Morse?
[07:56] <number10> maybe was just one letter
[07:56] <NigelMoby> Lol
[07:56] <number10> these are the tall tails of hams that are quite old
[07:56] <daveake> "I'll name that payload in 3"
[07:56] <number10> lol
[07:56] <fsphil> you can usually tell when a payload is falling too
[07:56] <number10> we could have a quiz
[07:57] <number10> ;-)
[07:58] <daveake> Then we can have a competition to see who can whistle the longest meaningful RTTY message.
[07:58] <daveake> Extra points for getting the checksum right.
[07:58] <fsphil> commander data is on my team
[07:58] <number10> lol
[08:01] <daveake> All I can do is distinguish the warble from noise ... when we chased my payload the radio was just mush for minutes then we got maybe half a second of warbling from the payload. We stopped PDQ to get the Yagi out :)
[08:02] <number10> were you far away at that point or was it on the ground?
[08:05] <daveake> It was on the ground.
[08:05] <fsphil> I'm sure landing in the tree helped me - thinking back I'm not sure we'd have heard the signal if it hit the ground
[08:06] <daveake> I'm not sure how far away it was, but I'll check. I was too excited to notice how much further we drove!

[08:08] <daveake> I'm guessing 3 miles or maybe a bit more. The direction it was in was directly down a particular road which stopped after 2 miles, and we had to go a different route so it was more than 2 miles.
[08:08] <fsphil> still no word on yesterdays launch
[08:09] <daveake> Was that the Geneva one that got mentioned?

[08:09] <fsphil> yea
[08:09] <fsphil> we where a bit concerned that it relied only on gsm
[08:09] <daveake> Oh
[08:10] <daveake> The video that got me started on this thing only had GSM. I did think they were a bit lucky to get it back!
[08:10] <daveake> I don't like the idea of relying on one of anything really :-).
[08:11] <fsphil> it's a great backup, saved many a payload
[08:11] <daveake> I bet
[08:11] <fsphil> I'm just as foolish relying on the radio
[08:11] <daveake> I had one. Didn't work though ... maybe it got upside down in the box.
[08:12] <daveake> I was going to have an old mobile phone sending texts too, but I couldn't get the code for that fitted in to the main program - just ran out of space and I ran out of time to sort it.
[08:13] <daveake> I had a seperate program sending texts just fine, so it was a shame to falter at the last hurdle.
[08:13] <fsphil> got a gsm module here, may fly it next time
[08:13] <daveake> Which one?
[08:14] <fsphil> "ADH8066 GSM Module" + breakout board
[08:14] <fsphil> I got it for a boat project, but will probably fly it first
[08:14] <number10_> has anyone used TX3H enabled on landing in addition to the NTX2 for tracking
[08:15] <daveake> Ah, not heard of that one. I have a wavecom. The Siemens TC35 seems popular.
[08:16] <fsphil> Trouble with the tx3h is the limited receiver options
[08:17] <fsphil> I've only done some limited testing with it, but I wasn't able to get as much range as the ntx2 (not line-of-sight though)
[08:17] <number10_> thats interesting
[08:17] M0JSN (516ada42@gateway/web/freenode/ip.81.106.218.66) joined #highaltitude.
[08:17] <fsphil> I was using the funcube dongle as a receiver - it's possible it's just not as sensitive at 869mhz
[08:17] <daveake> I tested an easyradio thing and got maybe 300 metres out of it; the NTX2-->AR800 ran for over a mile till I went over a hill.
[08:18] <fsphil> 300m isn't bad for a proper modem thingy
[08:18] <daveake> Yep
[08:19] <daveake> Maybe useful for remote cut-down from a tree
[08:19] <fsphil> ooh
[08:19] <fsphil> yes
[08:20] <fsphil> with a good yagi on the ground, I wonder what range you'd get to a payload with the easy radio
[08:21] <fsphil> what frequency do they use?
[08:21] <number10_> what about detecting if alt < 500, and if altidude does not change over a period of 5 minutes - cut
[08:22] <fsphil> what if you're dangling from a tree over a river? :) (has happened)
[08:22] <number10_> ohh ar, thats not good
[08:23] <daveake> fsphil - I'll check the frequency tonight, but it's 433Mhz-ish
[08:23] <fsphil> http://img.youtube.com/vi/B-o9fDeFYkE/0.jpg
[08:23] <daveake> luvvit!
[08:24] <fsphil> only case where a payload was saved by a tree :)
[08:24] <number10_> lol
[08:24] <daveake> I think the state of mine was helped by the tree branches slowing it a little :)
[08:25] <daveake> My next work jobbie is GPS tracking of cars via UHF radio. Happy days :)
[08:26] <fsphil> cool!
[08:27] <number10_> thats would do the trick but takes the fun out of it http://www.iridium.com/products/Iridium9602.aspx?productCategoryID=2
[08:27] <fsphil> aprs, next :)
[08:29] <daveake> It's for the WRC. The current tracking system has all the cars on the same frequency, taking turns to transmit their location. It can take nearly 10 seconds for the larger rallies to cycle through all the cars. They want 1 second updates from selected cars.
[08:30] <daveake> So it'll be several frequencies with the cars commanded to switch to a certain frequency, update rate, and position in the cycle.
[08:30] <fsphil> aah, that sounds fun
[08:31] <daveake> So the control centre guys can decide which cars to watch closely (i.e. the top guys when on a stage). Base sends commands out which the cars receive so they switch correctly.
[08:31] <daveake> If they don't hear a command they switch back to the old system.
[08:31] <daveake> Well that's the theory; it'll be my fault of it all goes pear-shaped!
[08:31] <Elwell> daveake: nice timing - see http://blog.elwell.org.uk/2011/08/shuttle-bus-tracker.html -- Any hardware suggestions?
[08:34] <daveake> Any GPS module + GSM module (e.g. TC35) + 2-line LCD + processor board of your choice. Easy peasy :)

[08:35] <Elwell> yeah, thats what I figured. I'm guessing the off the shelf ones want to sell you the entire app suite too tho
[08:36] <daveake> I was wondering ... what's the height record for a UK HAB?
[08:37] <daveake> Using the calculators it shows it's quite difficult to get to 140,000 or more

[08:39] <Elwell> yup - he'e just nipped to get more cloths

[08:50] <Darkside> did you get your payload bck?
[08:51] <elyptikus> hey darkside

[08:51] <fsphil> Nova 19 / Weasel - 36206 m
[08:51] <fsphil> oh nice one elyptikus
[08:51] <Darkside> very nice
[08:51] <number10_> nice pic
[08:51] <Darkside> so i guess it got lock on the ground?
[08:51] <Darkside> and got phone signal
[08:51] <fsphil> was getting a bit worried when we didn't hear from you yesterday :)
[08:52] <elyptikus> haha everything worked perfectly
[08:52] <elyptikus> i lost the phone signal after 2 minutes :D
[08:52] <Darkside> don't rely on those GSM trackers tho
[08:53] <elyptikus> but after 1.30 h it came back
[08:53] <Darkside> if it landed in somewhere without phone signal you'd have lost the payload
[08:53] <Darkside> oh 1.5 hours?
[08:53] <Darkside> hmm
[08:53] <Darkside> fsphil: 20km/
[08:53] <Darkside> elyptikus: do you know what your ascent rate was?
[08:54] <elyptikus> no unfortunately not... but think it was very fast :D once i got a SMS of my GPS which send me a speed of 80 km/h ^^
[08:54] <Darkside> nah, thats horizontal speed
[08:55] <Darkside> i'm interested in vertical speed
[08:55] <Darkside> it means we can figure out a rough maximum height
[08:56] <elyptikus> hmm... how can i find that out?
[08:56] <Darkside> do you have any logs from the gps?
[08:56] <NigelMoby> Balloon size and amount of helium used might help..
[08:57] <Darkside> GPS logs may tell us a lot
[08:57] <fsphil> the picture at least looks like it got near 30km
[08:57] <Darkside> fsphil: but getting phone signal again in 1.5 hours?
[08:57] <Darkside> actually that could be right...
[08:57] <fsphil> yea
[08:58] <elyptikus> i filled in 4000 L of helium to a 800 g ballon
[08:58] <fsphil> or maybe not
[08:58] <Darkside> thats gonna burst early
[08:59] <fsphil> how heavy was the payload elyptikus?
[08:59] <elyptikus> habhub.org/predict tells me 27538 meters
[08:59] <elyptikus> 1000 g
[08:59] <elyptikus> was the payload
[09:00] <fsphil> 26km would be a good guess
[09:00] <fsphil> the ascent rate would have been about 5.5m/s
[09:02] <fsphil> yikes, the predictor is working
[09:03] <elyptikus> thank you all for your help...
[09:03] <fsphil> yea, it says a 5.5m/s ascent, and 26km burst with a fairly quick descent is about 1.5 hours
[09:03] <fsphil> well, 1 hour 40 minutes
[09:04] <fsphil> was it easy to recover?
[09:04] <fsphil> shame I can't launch tomorrow: http://habhub.org/predict/#!/uuid=b705a408ef5be7104564bff41440a01f4d95143b
[09:05] <fsphil> actually no, it's a pesky forest
[09:05] <fsphil> grrr
[09:05] <fsphil> silly trees
[09:06] <elyptikus> yes it was very easy :D

[11:55] <cuddykid> no one seems to want helium balloons in worcester :(
[12:03] <fsphil> tried making little animal shapes out of them?
[12:05] <cuddykid> well, atm, I've just advertised in 2 POs for helium balloons (e.g. party)
[12:05] <fsphil> ah, will take a little time probably
[12:05] <cuddykid> wonder if I could just wonder round the city with a bunch of balloons without permit/licence ?!
[12:06] <hibby> the weather is unreal.
[12:06] <hibby> it's gnarly storm o'clock here

[12:06] <cuddykid> lovely here
[12:06] <rjharrison_> fsphil, not much better here
[12:07] <rjharrison_> Upu, about today?
[12:07] <fsphil> I'd even be happy with a bit of rain at this point :)
[12:07] <fsphil> howdy rjharrison
[12:07] <hibby> 1" hail
[12:07] <hibby> lightning every 2-3 seconds
[12:07] <number10> where are you hibby?
[12:07] <hibby> storm cell is huge
[12:07] <cuddykid> awesome hibby!
[12:07] <fsphil> Elwell, you got any lightning there?
[12:07] <hibby> Cincinnati
[12:08] <hibby> Ohio
[12:08] <cuddykid> hibby: is the weather channel doing a nut (if you have it!) ?
[12:08] <number10> is it still hot there?
[12:08] <hibby> The storms like, hundreds of square miles by the look of it.
[12:08] <hibby> cuddykid: not working, lol
[12:08] <hibby> we have the local channel
[12:08] <cuddykid> lol
[12:08] <hibby> directv is down
[12:08] <hibby> but dish network is still up
[12:08] <cuddykid> love when the weather channel is beeping at you! haha
[12:08] <hibby> it's a "mesocyclone" storm
[12:09] <cuddykid> cool!
[12:09] <hibby> Downtown Cinci is unbelievable
[12:09] <hibby> thre's like... 50m visibility.
[12:09] <fsphil> wish I was there
[12:09] <cuddykid> could someone point me in the right direction& I want to store up the characters received from serial and then output them as string rather than one by one :S
[12:09] <cuddykid> same fsphil
[12:10] <fsphil> on an avr?
[12:10] <cuddykid> yeah, arduino
[12:10] <fsphil> interrupts are the best bet
[12:10] <cuddykid> will google, thanks
[12:10] <fsphil> you can enable an interrupt that is fired each time a character is received
[12:10] <fsphil> then your interrupt handler just adds it to a string
[12:10] <edmoore> cuddykid: definitely interrupts
[12:11] <edmoore> on the avrfreaks forum, in the tutorial section, you will see a tutorial on interrupts and serial communications by a chap called abcminiuser
[12:11] <cuddykid> cheers :)
[12:12] <edmoore> it is *excellent* and you will come away with a great deal more insight into embedded development

[12:18] <hibby> they'll tax it.
[12:18] <NigeyS> hah yeah, its taking the coastal route mind...lol
[12:19] <number10> has to gor through customs
[12:19] <NigeyS> dam, better get it a passport :p
[12:20] <hibby> pay tolls to go over that bridge
[12:20] <number10> hey NigeyS, you have it bursting at 5000 - is there a way that you worked this out?
[12:21] Action: fsphil thinks that's a bit optimistic :)
[12:21] <NigeyS> nope, its purely guess work
[12:21] <NigeyS> 2 previous flight .. 1 burst at 2.1km 1 burst at 7k so im gone in between hehe
[12:21] <number10> so it may not need a passport ;)

[12:22] <hibby> I mention some of the height/etc choice on the skypod page iirc
[12:22] <NigeyS> if i went and launched now from the garden ^^
[12:22] <fsphil> nice to have the predictor working again
[12:23] <NigeyS> yush, ill probably break it though hehe
[12:23] <hibby> number10: http://ukhas.org.uk/projects:skypod#balloon is a basic summary of what to think about
[12:23] <NigeyS> wouldnt mind a garden launch, but tracking wouldnt be fun to many buildings
[12:24] <number10> thanks hibby
[12:25] <hibby> NigeyS: it's come in useful already!
[12:25] <NigeyS> yey!
[12:26] <fsphil> I bet that satellite tracking setup could receive a 10mw 1200 baud signal over a good distance
[12:26] <hibby> more than likely.
[12:26] <hibby> we still has S8 when skypod was over Northumbria
[12:27] <hibby> and that's possibly with the preamps off, as I dunno how they work
[12:27] <hibby> (the docs are in german)
[12:27] <fsphil> lol
[12:27] <hibby> and a high swr on the mast
[12:27] <hibby> as we're missing a shorting bar or two
[12:28] <fsphil> I've started building a second computer to fly on the next one, it'll be doing 1200 baud + the GSM modem
[12:28] <hibby> sweet.
[12:28] <hibby> I've started the blimp design.
[12:30] <fsphil> even sweeter
[12:31] <Laurenceb> blimp?
[12:32] <hibby> im planning a blimp, for personal entertainments
[12:35] <edmoore> hibby: yo
[12:35] <edmoore> i've done some blimp stuff
[12:35] <Laurenceb> nice
[12:36] <hibby> Wasn't planning on going high, as AFAICS it's not allowed
[12:36] <edmoore> what kind of size?
[12:37] <hibby> Not sure yet. Aany suggestions?
[12:38] <Elwell> fsphil: nope, had about 7 spots of rain so far tho

[12:38] rjharrison_ (~rjharriso@gateway.hgf.com) left irc: Quit: Leaving
[12:38] <edmoore> what kind of payload size?
[12:38] <edmoore> this is my one: http://www.youtube.com/watch?v=K29dn0Mzspk
[12:38] <hibby> likely circa 2Kg
[12:38] <Elwell> looks like thunderstorms are south east of here http://www.blitzortung.org/Webpages/index.php?lang=en&subpage_0=4
[12:38] <edmoore> it had a payload of 3kg
[12:39] <edmoore> that was instrument payload, there was another 4-5kg of batteries and motors in the front pod
[12:39] <hibby> Yeah, thats where I figured most of the weight was coming from
[12:41] <edmoore> you can have
[12:41] <edmoore> scrap that
[12:41] <edmoore> you definiotely should have more mass hanging off it than there is lift
[12:41] <edmoore> so that it sinks
[12:41] <edmoore> this is so you get it back if something goes wrong
[12:41] <hibby> and use fans for extra lift after that?
[12:41] <edmoore> which is exactly what happened when i noticed total motor failure in this video http://www.youtube.com/watch?v=N9Ec9fuy5zc&feature=related
[12:42] <edmoore> yes - you always keep some forward + elevator to maintain alt
[12:42] <hibby> spotted that
[12:42] <edmoore> of vector the fans down slighly, tho that's much less efficient
[12:43] <hibby> yeah. Did you have separate EL/fwd fans/
[12:43] <hibby> doesn't look like it
[12:43] <edmoore> the only time i vector the fans is for landing or just thrashing it around to see what it can do in terms of aerobatics
[12:43] <edmoore> http://www.youtube.com/watch?v=_0m0jEfR_iw
[12:43] <edmoore> you can see about the 40s mark in that video i vector down to slow the descent before neill catches it
[12:44] <edmoore> all-in-one fans
[12:44] <hibby> and you had controllable surfaces by the look of it.
[12:44] <edmoore> and a fan on the tail for low speed rudder
[12:44] <edmoore> a sideways fan, that is
[12:44] <hibby> aha
[12:44] <hibby> bbs ~ taking the excuse of having 15 minutes free to get a shower.
[12:44] <edmoore> ok
[12:44] <edmoore> ttyl
[12:45] <hibby> cool
[12:45] <NigeyS> hrm ..
[12:45] <NigeyS> A radical alternative is the torus balloon – a doughnut with the spaceplane blasting through the hole. It's a lovely thought, and if any of you can find one, we're prepared to look into it, or indeed through it.
[12:46] <NigeyS> thereg have lost the plot
[12:46] <edmoore> lol
[12:46] <edmoore> link me to the latest reg?
[12:46] <NigeyS> http://www.theregister.co.uk/2011/08/03/lohan_balloons/
[12:46] <Laurenceb> they have lost it now
[12:47] <NigeyS> totally
[12:47] <edmoore> so about 2006 we (cusf) sat in a pub garden for about 3 hours
[12:47] Jasperw (~jasperw@62-2-134-218.static.cablecom.ch) left irc: Ping timeout: 255 seconds
[12:47] <edmoore> got through about 200 sheets of a4 paper, covered in scribbles, calcs, diagrams
[12:47] <edmoore> trying to figure out how to make a rockoon miss the balloon
[12:47] <edmoore> then someone piped up and suggested we could just fly straight through the damn thing
[12:48] <NigeyS> lols !!
[12:48] <edmoore> we'd be doing mach 1 by the time we hit it
[12:48] <edmoore> so that's still the plan
[12:48] <NigeyS> the latex is fairly frittle too isnt it, as it gets colder ?
[12:48] <NigeyS> brittle*
[12:48] <edmoore> it's super thin by that point
[12:48] <edmoore> just a few microns
[12:49] <NigeyS> ah right
[12:49] <edmoore> and the noise of our rocket is a polished aluminium point
[12:49] <edmoore> with sharp leading edges on the fins too
[12:49] <NigeyS> yup i can see that working!
[12:49] <edmoore> so it should just slice through
[12:49] <NigeyS> hot knife through butter ..
[12:50] <NigeyS> The Vulture 2 should go before the balloon burst because if we try and concoct some method of detecting the balloon's disintegration, we're just going to be adding another layer of systems complexity.
[12:50] <edmoore> hibby: shout when you're back
[12:50] <NigeyS> heh its not that complex :|
[12:50] <edmoore> yes
[12:50] <edmoore> burst before launch = write-off
[12:51] <edmoore> just launch it at an altitude conservative for the balloon
[12:51] <NigeyS> yip
[12:51] <NigeyS> what was this i read about a 45degree angle ?
[12:51] <edmoore> madness
[12:51] <NigeyS> couldnt make sense of it
[12:52] <edmoore> oh this has all made me want to fly blimps again
[12:52] <edmoore> they're really fun
[12:53] <NigeyS> hehe, fly 1 somehwere warm next time? :p
[12:53] <edmoore> hmm perhaps
[12:53] <edmoore> though it was actually pretty hot in the sun
[12:54] <edmoore> my face still hasnt recovered
[12:54] <hibby> shout
[12:54] <edmoore> and it was pretty stunning round there
[12:54] <NigeyS> ouch
[12:54] <edmoore> hibby: yo
[12:54] <number10> nicely caught blimp
[12:54] <edmoore> so would you like a blimp that can take about 2kg of your own stuff on top of the base propulsion?
[12:54] <edmoore> thanks
[12:54] <edmoore> i had a few bad landings too :)
[12:55] <edmoore> just tended not to film them!
[12:55] <number10> oh - you did not show those ;)
[12:55] <edmoore> you have to landing facing into the wind at the winds around the mountains could be a bit fickle

[12:55] <hibby> did you guys have an internal skeleton or was the shape managed by the shape of the balloon?
[12:55] <edmoore> well unless the blimp itself is the project, i really recommend buying one off the shelf to hack with
[12:56] <edmoore> theres a surprising amount of iteration and faff that goes into building one
[12:56] <hibby> cool
[12:56] <hibby> are they easy to source?

[13:17] <Zuph> Is anyone aware of a cheap microcontroller dev board with ethernet and a couple of serial ports that *isn't* PIC based?
[13:17] <hibby> edmoore: totally
[13:17] <Zuph> edmoore: Have it drag up some thin wire :)
[13:17] <edmoore> Zuph: arduino mega has 4
[13:17] <hibby> edmoore: I reckon the idea they pushed in twister has some legs in a mini balloon style.
[13:17] <edmoore> yes
[13:17] <number10> go one go for a pic
[13:17] <edmoore> agreed
[13:18] <hibby> no reason a mesh network can't be done
[13:18] <edmoore> i was looking at a bunch of tiny payloads with party balloons that are just about bouyant, with a zigbee mesh
[13:18] <Zuph> I like that idea.
[13:18] <edmoore> and then take them up attached to a line (like a bunch of grapes) with a big tow latex balloon
[13:18] <edmoore> then pyrotechically release them all into the belly of a storm cell

[13:19] <Zuph> edmoore: Yeah, arduino mega + ethernet sheild looks like the best bet for quick and easy. I was just hoping for something more... integrated.
[13:19] <edmoore> sure
[13:20] <edmoore> not sure of anything off the top of my head
[13:20] <edmoore> apart from Big Stuff (tm) like beagleboard and ftdi chips
[13:20] <hibby> could always go the more barebones route and get a standard arduino, use the new software serial library
[13:20] <hibby> and get an ethernet controller.
[13:20] <SpeedEvil> Zuph: ethernet and one serial port - biffer
[13:20] <Zuph> Def. need two serial ports. Plus, afaik, no US distributers of biffer.
[13:21] <hibby> and usb ports for further expansion
[13:21] <SpeedEvil> USB-serial
[13:21] <SpeedEvil> Though you cna use a couple of the other ports if you did soft-serial
[13:21] <Zuph> Maybe I'll take a glance at softserial. Sparkfun does have a nice board based on a 328.

[14:43] <edmoore> they rejected the guy who came top in my year twice
[14:43] <cuddykid> wow
[14:43] <edmoore> tho i think that might be because they thought he might get itchy feet

[15:04] <Darkside> they're launching arissat
[15:04] <Darkside> i wonder how they're gonna deploy it

[15:58] <edmoore> nickolai: it's the manufacturer
[15:58] <edmoore> there are two balloon manufacturers
[15:58] <nickolai> so i suppose what really matters is how many grams then
[15:58] <edmoore> their balloons have slightly different mechanical properties
[15:58] <edmoore> the predictor needs to know which one you are using for its internal lookup table
[15:59] <nickolai> hm, i ordered a different balloon entirely, since i',m in the us and i assume those are uk manufacturers?
[15:59] <edmoore> no
[15:59] <Randomskk> what manufacturer did you use?
[15:59] <edmoore> they're international
[15:59] <Randomskk> totex is like kaymont

[16:04] <GW8RAK> Stay they've organised themselves, the live feed is back on.
[16:04] <nickolai> i evnetually plan to launch what I see the UKHAS website calls a Rockoon
[16:04] <edmoore> nickolai: gosh
[16:04] <edmoore> v difficult
[16:04] <edmoore> and v exciting
[16:05] <nickolai> yea i'm trying to launch the balloon on saturday, then on sunday i'm going for my level 1 certification with the National Association of Rocketry so I can eventually buy some powerful motors for me rockoon :)
[16:05] <edmoore> nice
[16:05] <nickolai> also to build up some highpowerrocketry skills
[16:05] <edmoore> what kind of alt do you want to reach?
[16:05] <nickolai> i dunno, high as i can get
[16:06] <nickolai> i want to try to beat that 36km record
[16:06] <edmoore> oh easy peasy
[16:06] <nickolai> but as long as the rocket ignites and has a good flight i'll be happy
[16:06] <edmoore> aim high!
[16:06] <nickolai> there are so many more things that can go wrong haha
[16:06] <edmoore> it's a completely different thing altogether really
[16:07] <nickolai> i would jsut say it's more stuff to do
[16:07] <edmoore> getting a circuit board to 30km vs getting an entire launch tower to 30km and launching something from it
[16:07] <nickolai> yea but that whole thing needs the circuit board on it, so it's the same basics
[16:08] <nickolai> and who said anything about a launch tower :P

[16:09] <nickolai> i'm thinking i'll just have the rocket hanging down from the balloon at an angle large enough to miss an inflated+expanded-by-vaccuum ballon

[16:09] <nickolai> like what?

[16:09] <Randomskk> if it's hanging and pointing at an angle I'd be pretty seriously concerned about how far sideways it's gonna go :P
[16:09] <nickolai> oh yeah but i can ground launch the rocket and check all that out
[16:09] <edmoore> things like gps will loose lock above 4G so you might not see how high it gets
[16:09] <nickolai> the vibrations and all
[16:10] <fsphil> heat might be a problem? no air cooling
[16:10] <nickolai> yea, that's a concern
[16:10] <nickolai> heat from the rocket exhaust?

[16:10] <edmoore> it'll happen. you might get contact again during coast after burnout though
[16:10] <edmoore> as you're in freefall
[16:11] <nickolai> i'll just have the motor sticking out the back a few inches
[16:11] <fsphil> (no rocket experience at all, so ignore most of what I say :)
[16:11] <nickolai> another concern is speed, since the solid rocket can go several times the speed of sound, regardless of g issues the gps might lockdown based on being rated to only 999 knots or so
[16:12] <nickolai> no worries fsphil, all comments welcome :)
[16:12] <edmoore> i think heat management should be ok for a small rockoon. but if you're spending minutes+ at >40km it need some thought
[16:12] <number10> no experience of anything - so ignore anything I say
[16:12] <nickolai> what makes you say that edmoore?
[16:12] <edmoore> nickolai: this is our rocket prototype

[16:12] <fsphil> that's what I was thinking of - remember the last video of a sub-orbital rocket, the heat killed one of the cameras
[16:12] <edmoore> we are working ona rockoon too, you see
[16:12] <fsphil> and that was just the sun
[16:12] <edmoore> but aiming for 100km
[16:13] <nickolai> oo nice
[16:13] <nickolai> oo very nice
[16:13] <edmoore> we are building our own diy gps to keep lock under the high dynamics
[16:13] <nickolai> damn, that sounds tough
[16:13] <number10> I see the beck cans are empty edmoore
[16:13] <edmoore> we've done some ground launches, it's gone supersonic
[16:13] <fsphil> that's pretty hardcore
[16:13] <nickolai> i must admit, i particularly like the stand

[16:13] <edmoore> it's thirsty work
[16:13] <nickolai> how much does it weigh?
[16:14] <nickolai> lol
[16:14] <edmoore> about 4kg loaded, 1.5kg without fuel
[16:14] <nickolai> and what are your weight restrictions in the uk?
[16:14] <nickolai> that is, weight restrictions for balloon payloads?
[16:15] <fsphil> do you make your own motors? or off the shelf?
[16:15] <edmoore> this shows your our mold http://www.flickr.com/photos/cuspaceflight/sets/72157621632629963/
[16:15] <edmoore> off the shelf fsphil

[16:15] <fsphil> must get a look at these pics when I get home
[16:15] <edmoore> fsphil: that one is designed for an 'L' motor
[16:15] <nickolai> that's big!
[16:15] <edmoore> she's looking at 50G acceleration
[16:16] <nickolai> that's a lot!
[16:16] <edmoore> and mach 4+
[16:16] <nickolai> lol
[16:16] <nickolai> that's fast!
[16:16] <edmoore> hence all the effort to grok carbon fibre
[16:16] <nickolai> you guys must have a pretty nice budget
[16:16] <edmoore> so it'll be a roughly 2 second burn from our launch gondola and a 70km coast
[16:17] <edmoore> nickolai: nope, peanuts compared to the US groups
[16:17] <nickolai> which groups?
[16:17] <edmoore> a group at MIT got given $15,000 to start a rocket club
[16:17] <nickolai> lucky
[16:17] <edmoore> we didn't spend that in our first 3 years
[16:17] <edmoore> we just blag lots

[16:17] <Randomskk> are MIT working on an actual rockoon?

[16:20] <hibby> edmoore: cool
[16:20] <hibby> worktimes
[16:20] <nickolai> nice
[16:20] <hibby> I've got fedora living on my memorystick for when I'm not here
[16:21] <hibby> but they'd notice if I reformatted the HDD and installed linux, as it's all encrypted and such
[16:21] <edmoore> nickolai: as Randomskk says, the cuspaceflight website is pretty out of date
[16:21] <nickolai> fairenough, i don't really keep my blog updated either
[16:21] <Randomskk> eroomde: if ed c doesn't so something soon I might try making a basic sexy looking skin. all we want is a pretty full-screen space background with some text and stuff
[16:21] <edmoore> but we also have not done much rocket work as we got flattened by some contract work for ESA
[16:21] <hibby> that is one hot website.
[16:21] <edmoore> thanks
[16:22] <nickolai> so edmoore, what's your plan for launching the rocket from the balloon (i.e. launch tower?)
[16:22] <edmoore> nickolai: we'll have to go abroad

[16:23] <edmoore> a realistic campaign abroad will cost uis about $30,000
[16:23] <edmoore> that's big money, so we can't do it lightly
[16:23] <edmoore> so there'll be lots of testing work done in the uk before we plan on launching from a free balloon
[16:23] <nickolai> no i mean how are you going to keep the thing pointing in the right direction at launch?
[16:23] <edmoore> oh
[16:24] <edmoore> a carbon fibre version of the launch tower you saw in that pic
[16:24] <edmoore> and p[robably spinning
[16:25] <nickolai> that's gonna be heavy as fuck
[16:25] <hibby> how much does fuck weigh?

[16:26] <nickolai> good, waiting for my level1 cert kit to arrive by fedex
[16:26] <nickolai> come join the fun, we're talking about rockoons
[16:26] <SpeedEvil> edmoore: How do you cope with the fact that you are required if you are controling the launch to register even if you are outside the UK?
[16:26] <SpeedEvil> edmoore: For a launch that qualifies as space in the outer space treaty.
[16:26] <SpeedEvil> If that's the corect act.
[16:27] <SpeedEvil> Outer space act.
[16:27] <edmoore> SpeedEvil: not crossed it don't care yet
[16:28] <SpeedEvil> ah
[16:28] <edmoore> david willets was keen on some of our stuff

[16:29] <nickolai> i'm confused, your website says you're trying to do this for less than (pound sterling symbol)1000? or is that outdated as well?
[16:29] <edmoore> per launch
[16:29] <edmoore> feasible
[16:29] <nickolai> so the $30,000 is essentially your development costs?
[16:30] <edmoore> no, the cost of getting 4 people and 500kg of equipment to a remote site for a month
[16:30] <edmoore> that's the campaign cost
[16:30] <edmoore> that's me being realistic
[16:30] <hibby> thats a lot of food.
[16:30] <edmoore> calculate costs and multiply by 3
[16:30] <hibby> and booze.

[16:31] <Lunar_Lander> xD
[16:31] <edmoore> try and get flights sponsored
[16:31] <edmoore> we'd obv try and get a shipping company to sponsor us a container and delivery
[16:32] <SpeedEvil> This is an n-prize thingy?

[16:32] <SpeedEvil> Are you aiming for orbit or ...
[16:32] <SpeedEvil> ah
[16:33] <hibby> so your rocket is going to come crashing down on some poor guys house?
[16:33] <edmoore> parabolic + parachute
[16:33] <edmoore> parachuting is really tough for this
[16:33] <SpeedEvil> edmoore: not with the right sponsor.
[16:33] <nickolai> at what altitude are you going to deploy the parachute?
[16:33] <SpeedEvil> edmoore: Have you approched the makers of Shreddies?

[16:40] <fsphil> a lot of people are not happy about how they handled the satellite.. they where apparently quite rough with it
[16:40] <hibby> they just need more competent astronauts
[16:40] <Lunar_Lander> damn
[16:41] <edmoore> nickolai: about 3 of us worked on the rocket
[16:44] <nickolai> just called scientific sales, their balloons are kaymont
[16:44] <edmoore> cool
[16:44] <edmoore> nickolai: get a friend or two to help with the rocket
[16:44] <edmoore> just makes it easier to carry on working late
[16:44] <nickolai> tru
[16:45] <edmoore> or push through to the end of a very boring job
[16:45] <edmoore> especially useful if doing composite layup
[16:45] <nickolai> yea it's gonna be tougher with school starting up and i'm only there for one more semester
[16:45] <edmoore> yup, we were allways evenings and weekends
[16:45] <nickolai> but yea, working in groups is a lot easier and a lot more fun
[16:45] <edmoore> it's tough to find the time to do stuff
[16:46] <nickolai> i know, there's so much i want to do in my last semester!
[16:46] <edmoore> any plans for afterwards?
[16:46] <nickolai> get a job in commercial spaceflight
[16:46] <nickolai> like one of the CCdev2 companies
[16:47] <hibby> your plans are better than mine
[16:47] <hibby> I want to go to australia and live in a van.
[16:47] <nickolai> hahahahahaha

[16:47] <nickolai> rotfl
[16:47] <edmoore> nickolai: stay small
[16:47] <hibby> but I always have. However instead of being that crazy junkie in the van, I can be that engineer in the van.
[16:47] <edmoore> don't work for someone big, or nasa
[16:48] <edmoore> it's just not fun
[16:48] <nickolai> i worked at spacex last summer, it was pretty fun
[16:48] <edmoore> that's more like it :)
[16:48] <nickolai> although they're far past the "small startup company" phase
[16:48] <edmoore> yes true
[16:48] <edmoore> but they have the mentality
[16:48] <nickolai> blue origin seems cool, and small enough for now
[16:48] <nickolai> but they don't anything
[16:48] <nickolai> *don't do
[16:48] <edmoore> exactly
[16:49] <hibby> lol
[16:49] <edmoore> and bezos sounds like a bit of a dick
[16:49] <nickolai> how so?
[16:50] <edmoore> trying to apply his mentally mutilated approach to software patents to his rockets
[16:50] <nickolai> oh yea, i was actually talking to dave masten about that a few weeks ago when i was in florida
[16:51] <Lunar_Lander> so can you really launch into orbit from the balloon?
[16:51] <nickolai> he was telling me how he's brought in legal counsel to review some of the blue origin patents because they look a hell of a lot like designs that masten has presented in conferences and such
[16:51] <hibby> ugh
[16:52] <hibby> legal wars everywhere. sad times.
[16:52] <edmoore> the us patent system is just f*cked beyond repair
[16:52] <edmoore> it needs starting over
[16:52] <nickolai> Lunar_Lander you can get into orbit from anywhere if you have a big enough rocket, but you're not going to get anywhere close to orbit with a couple solid rocket motors
[16:52] <Lunar_Lander> I know that
[16:52] <nickolai> so then what are you asking?
[16:53] <Lunar_Lander> opinions
[16:53] <edmoore> Lunar_Lander: i think it's perfectly possible
[16:53] <edmoore> but it would be making things much harder than they need to be
[16:54] <nickolai> the romanian space agency has been going that route, although i don't think they've made much progress
[16:54] <Lunar_Lander> I saw their concept
[16:54] <Lunar_Lander> that bulbous rocket
[16:54] <nickolai> https://www.arcaspace.com/en/home.php
[16:54] <Lunar_Lander> yeah
[16:54] <edmoore> energy-wise it saves you peanuts
[16:55] <edmoore> but the added complexity of launch is gigantic

[16:56] <nickolai> it might be a viable solution for small payloads but you're not going to get anything like space station modules up that way
[16:56] <Lunar_Lander> of course
[16:56] <nickolai> maybe if you went really high with the balloon and launched the rocket nearly horizontally you could get some good savings
[16:57] <nickolai> sorry i misunderstood you earlier. sometimes we hear what we want to hear i guess :P
[16:58] <SpeedEvil> nickolai: you basically can't.
[16:58] <SpeedEvil> nickolai: If your rocket is large enough, then the atmospheric drag is completely unimportant
[16:58] <SpeedEvil> It only impacts you as you have to throttle back for a few moments around mach several.
[16:59] <nickolai> drag losses can account for several hundred meters per second of deltav loss
[16:59] <SpeedEvil> Indeed.
[16:59] <SpeedEvil> But for large rockets, it falls to much lower.
[16:59] <nickolai> and my point about launching nearly horizontally is that you'll have reduced gravity losses
[16:59] <SpeedEvil> You launch horizontally, and you fall into the dense atmosphere
[16:59] <nickolai> for large rockets sure, but i'm saying for small payloads there could be some potential
[17:00] <SpeedEvil> You can't get high enough to be able to accellerate significantly horizontally on a balloon
[17:00] <nickolai> you can have a much larger launch angle at altitude than you can at sea level because you have so much less drag to worry about
[17:01] <SpeedEvil> At sea level, for small rockets, your first stage has to burn for a minute or so at around mach 1.
[17:01] <SpeedEvil> And only then can you accellerate.
[17:02] <SpeedEvil> This is of course vastly better if you launch from a balloon
[17:02] <nickolai> right, becuase of the dynamic pressure
[17:02] <SpeedEvil> No.
[17:02] <SpeedEvil> Because of the drag
[17:02] <SpeedEvil> If you try to accellerate to mach 3 at 5km, you simply burn oodles of fuel, for little result.
[17:03] <SpeedEvil> As a first order, drag goes as 1/length of rocket
[17:03] <SpeedEvil> Neglecting stuff.
[17:04] <SpeedEvil> (assuming constant aspect ratio rockets)
[17:05] <SpeedEvil> http://spacefellowship.com/Forum/viewtopic.php?f=7&t=11996&start=30
[17:05] <SpeedEvil> says gravity losses of saturn V at 40m/s
[17:06] <nickolai> *drag loss
[17:06] <SpeedEvil> err yes
[17:07] <nickolai> but we're talking about smaller rockets here. no way are you going to be able to work a saturn V class launcher from a weather balloon
[17:07] <SpeedEvil> Drag loss is made better by going slower in the atmosphere, launching higher, or having a bigger rocket. Gravity loss by going faster. Structural fraction is another plank.
[17:07] <SpeedEvil> nickolai: No, of course not. You'd need several.
[17:08] <nickolai> gravity loss also depend on your launch angle. the more horizontal you are, the less gravity loss you will have, right?
[17:09] <SpeedEvil> To a degree.
[17:09] <SpeedEvil> But you can't do that.
[17:09] <SpeedEvil> Even from a balloon, the air is very dense if you try.
[17:09] <SpeedEvil> It's only of the order of a percent as dense as at sea level, so you get the sameish drag as mach 1 as at mach 10
[17:09] <nickolai> really? at ~30km?
[17:10] <SpeedEvil> More like a fifth of that
[17:10] <SpeedEvil> but ish
[17:10] <nickolai> hm
[17:11] <SpeedEvil> So going more horizontal helps, but you still need to get to the required altitude before doing most of the accelleration.

[19:47] <Darkside> is it following the ISS?
[19:48] <fsphil> it will for the moment

[19:56] <Darkside> just do a 10 minute scheduled recording at 0120Z
[19:57] <fsphil> you got software that can do that?
[19:57] <Darkside> spectravue will do it
[19:57] <fsphil> I'm probably going to use the at command
[19:57] <Darkside> i'm gonna set it recording the entire output from the funcube dongle
[19:57] <Darkside> so i should get 90KHZ of spectrum
[19:58] <fsphil> aah
[19:58] <Darkside> i'll do some testing now tho
[19:58] <fsphil> not sure I can setup the funcube for that .. the cable in the attic end in a pl-259
[19:58] <fsphil> dongle*
[19:58] <fsphil> I keep calling it the funcube -- that's the satellite
[19:58] <Darkside> i have adaptors ol
[19:58] <Darkside> heapss of them
[19:59] <Darkside> and im not gonna have a proper antenna..
[19:59] <fsphil> I've adaptors too, but none are direct :)
[19:59] <Darkside> its gonna be a quarter wave on 70cm..
[19:59] <Darkside> since its all i have
[19:59] <fsphil> it'll be PL-259 to N to BNC to SMA :)
[19:59] <Darkside> hahaha
[19:59] <Darkside> youdon thave PL-259 to BNC?
[19:59] <Darkside> hmm, i wonder if i should use my 70cm cross-dipole for this
[19:59] daveake (d49f57d3@gateway/web/freenode/ip.212.159.87.211) left irc: Quit: Page closed
[19:59] <Darkside> i guess it would be better than just a 1/4 wave
[20:00] <fsphil> I have PL-259 to BNC, but I'd need the SO-2xx whatever to BNC
[20:01] <Darkside> i wonder if theres anything else passing tonight
[20:01] smea (~smealum@82.243.132.64) joined #highaltitude.
[20:02] <fsphil> HO-68 is overhead right now
[20:04] <fsphil> ooh small thunderstorm over cambridge
[20:05] <Darkside> too late
[20:05] <Darkside> damn
[20:06] <Darkside> hamsat is next
[20:06] <fsphil> does that still work?
[20:08] <fsphil> ah it is
[20:08] <Darkside> cant hear anything
[20:10] <fsphil> nor here
[20:10] <fsphil> aah
[20:10] <fsphil> hear the CW beacon
[20:10] <Darkside> you can
[20:10] <Darkside> ?
[20:10] <Darkside> i cant, but i have an antenna tuned to 70cm
[20:10] <fsphil> actually it's not shifting in frequency
[20:11] <fsphil> might not be the satellite I'm hearing
[20:12] <fsphil> fldigi isn't decoding anything from it
[20:12] <fsphil> sounds like CW though
[20:12] <Darkside> plus its below the horizon now
[20:12] <fsphil> SO67 next
[20:13] juxta (~juxta@ppp203-122-193-94.static.internode.on.net) joined #highaltitude.
[20:13] <Darkside> that only has a repeater
[20:13] <Darkside> and its dead
[20:13] <Darkside> http://www.amsatsa.org.za/
[20:13] <Laurenceb_> DarkSide:http://www.youtube.com/watch?v=oZkzcm7ubQg <- thats mor elike it
[20:15] <Darkside> fsphil: and next is oscar-50
[20:15] <Darkside> which is also only a repeader
[20:15] <Darkside> Laurenceb_: oooh
[20:15] <Darkside> Laurenceb_: i recon you'd like some of the stuff by Klippa
[20:16] <Darkside> http://lapfox.bandcamp.com/track/mixed-berry
[20:16] <fsphil> ooh that's good
[20:16] <Darkside> DAMMIT why are all these sats non-operational
[20:17] <fsphil> all future sats need an ability to de-orbit after they're done :)
[20:20] <Darkside> heh
[20:20] <Darkside> well ill get something set up at uni
[20:21] <Darkside> i might setup the SDR-IQ attached to an AOR receiver
[20:21] <Darkside> i think its an AOR 5000 or something
[20:21] <Darkside> yeah, an AOR AR5000
[20:21] <fsphil> loivly
[20:22] <fsphil> I'll leave the 817 connected tonight, try the fcd tomorrow if I hear anything
[20:22] <Darkside> and its has 10.7MHZ out
[20:22] <Darkside> fsphil: use the fcD tonight
[20:22] <Darkside> you need the bandwidth
[20:22] <fsphil> well the BPSK-1000 mode is tempting
[20:22] <fsphil> ah sod it, why not
[20:22] <Darkside> but it will shift
[20:22] <fsphil> not sure how I'm going to connect it
[20:23] <Darkside> re-terminate a cable? :P
[20:23] <fsphil> I've got a wee usb hub up there already for the usb sound card and rig control
[20:23] <fsphil> but when I last tried the dongle in it, it got very hot
[20:24] <Darkside> heh
[20:24] <fsphil> like, 'oh what's that burning smell' hot :)
[20:25] <Lunar_Lander> XD
[20:25] <Darkside> hmm
[20:25] <Darkside> i think ill do a proper setup at uni tomorrow
[20:25] <Darkside> AOR 5000 outputting 10.7MHz IF into my SDR-IQ
[20:26] <Darkside> and have the entire thing remote-controllable, and with timed recordings
[20:26] <fsphil> sweet
[20:26] <fsphil> spectravue doesn't seem to have a very good fm demodulator
[20:26] <Darkside> oh?
[20:26] <Lunar_Lander> for receiving satellites?
[20:26] <Darkside> it seemed to wor for me
[20:26] <Darkside> it just doesn't work in wine very well
[20:27] <fsphil> I've only used it with the fcd, so that might be an issue too
[20:27] <Darkside> i plan on recording raw I/Q data
[20:27] <Darkside> then dealing with the rest later
[20:27] <fsphil> when listening to the local repeaters, it's a bit tinny
[20:27] Futurity (~Futurity@cpc29-cmbg15-2-0-cust249.5-4.cable.virginmedia.com) left irc: Read error: Connection reset by peer
[20:27] Futurity (~Futurity@cpc29-cmbg15-2-0-cust249.5-4.cable.virginmedia.com) joined #highaltitude.
[20:27] <fsphil> and there's always bursts of noise I don't get with the 817
[20:28] <Darkside> 'tinny' is just an audio processing thing
[20:28] <fsphil> though I know the fcd has very little filtering so that probably explains the noise
[20:28] <Darkside> spectravue can do much wider bandwidth reception than anyting else
[20:28] <Darkside> and yeah, the fcd has a not very good frontend
[20:28] <Darkside> because its a very broadband tuner IC, and you can on;y do so well
[20:28] <Elwell> what are you using with the fcd? just spectraview?
[20:28] <fsphil> I need to get myself a 70cm pass filter
[20:29] <Darkside> i'm looking for something better to put on a sat
[20:29] <fsphil> I've only got spectravue working (on linux via wine)
[20:29] <fsphil> there's no good linux native alternatives that I can see
[20:29] <Darkside> fsphil: yeah, spectravues demodulators dont work well on wine
[20:29] <Darkside> fsphil: tried quisk?
[20:29] <fsphil> yea, works but seems very crude
[20:29] <Darkside> its a bit shit tbh
[20:29] <fsphil> indeedy
[20:30] <Darkside> spectravue seems to run reasonably well in wine, but the demodulators dont always work
[20:30] <fsphil> I'll stick with the 817 on the colinear, and use the funcube dongle down here with the whip
[20:30] <fsphil> my problem could be wine then
[20:30] <Darkside> yeah
[20:30] <fsphil> it sucks up an awful lot of cpu on wine too
[20:30] <Darkside> try it under windows if you can
[20:30] <Elwell> anyone used it with fl-digi?
[20:31] <fsphil> yea
[20:31] <fsphil> fldigi seems to only receive the very edge of its range
[20:31] <fsphil> where it's a bit deaf
[20:32] <fsphil> fldigi would be brilliant with >8000hz support
[20:32] <fsphil> rtty at 19600 baud :)
[20:32] <Darkside> fldigi takes one of the channels
[20:32] <Lunar_Lander> xD
[20:33] <Darkside> so it'll have 48000Hz of bandwidth available to it, and it takes thebottom 3KHz or so
[20:33] <Darkside> its a bit weird
[20:33] <fsphil> yea
[20:33] <Darkside> but yeah, fldigi with wideband support would be NCIE
[20:33] <Darkside> but it would mean re-coding almost the entire thing
[20:33] <fsphil> I've decoded my payload with that setup, when it was sitting on the desk
[20:33] <Darkside> its all hardcoded for 8KHZ, right?
[20:33] <fsphil> but it was rubbish at range
[20:33] <fsphil> mostly yea
[20:33] <fsphil> there's some modes that change it to 11025hz
[20:33] <Darkside> fuuu
[20:33] <Darkside> still shit
[20:33] <Darkside> needs to be adaptive
[20:34] <Darkside> but OH GOD that'd be horrible to code
[20:34] <fsphil> yea - the sample rate should be decided by the device, not the modem
[20:35] <Darkside> i swear this is the most awesome youtube video ever: http://www.youtube.com/watch?v=us6nQ_E9waE
[20:35] <fsphil> I tried spectravue with the funcube dongle on the range test, and I was easily able to decode the payload at 10km range
[20:37] <fsphil> lol
[20:37] <fsphil> damn I might have to watch cowboy bebop again
[20:38] <Darkside> how about you watch my little pony friendship is magic instead
[20:38] <Darkside> :P
[20:38] <hibby> mlp:fim ftw

[20:40] <hibby> hahahah
[20:40] <Darkside> because ponies are awesome?
[20:40] <Randomskk> yea I have like six my little ponies right here or something
[20:40] <Darkside> only G4 is awesome
[20:40] <Darkside> G1-3 are horrible mutants
[20:40] <Randomskk> :|
[20:41] <hibby> surely it'd be 4G
[20:41] <Darkside> G4 being the current generation of my little pony, G1-3 being the ones most people associate with my little pony
[20:41] <hibby> seeing as we're into tech :)
[20:41] <Darkside> heh
[20:41] <Darkside> true
[20:41] <Darkside> so... whats a good introductory pony video...
[20:42] <Elwell> ponies.xxx ?
[20:42] <Randomskk> :(
[20:42] <hibby> mr hands?
[20:42] <Randomskk> illegal in the UK actually
[20:42] <Darkside> >_>
[20:42] <Darkside> how about no
[20:42] <hibby> Legal in the states
[20:42] <hibby> well, regulated by state law\
[20:42] <Randomskk> yea
[20:42] <Randomskk> definitely illegal in some states >_>
[20:43] <hibby> aye
[20:43] <hibby> not enough, however...
[20:43] <Darkside> MLP has spwened some awesome fan music: http://www.youtube.com/watch?v=sf0tYs5U5RI
[20:43] Action: Elwell doesn't even want to know if ponies.xxx exists, but then rule 34? probably applies
[20:43] <Randomskk> the UK's new extreme porn laws are a bit silly?
[20:43] <hibby> there are new porn laws?
[20:43] <Elwell> yeah, old porn was black n white
[20:43] <hibby> I remember those days
[20:44] <Randomskk> https://secure.wikimedia.org/wikipedia/en/wiki/Section_63_of_the_Criminal_Justice_and_Immigration_Act_2008
[20:44] <Randomskk> those
[20:44] <Randomskk> anything a through d in the intro there is now illegal
[20:44] <Randomskk> but wasn't before
[20:44] <eroomde> what's habbening?
[20:44] <Darkside> and a reasonable person looking at the image would think that any such person or animal was real.
[20:44] <eroomde> (geddit!?!?!!!?)
[20:44] <Randomskk> eroomde: if I could kick you
[20:44] <Randomskk> I might
[20:44] <Darkside> now thats interesting
[20:44] <Elwell> err looks like I need an update to whois
[20:45] <Elwell> whois casting.xxx
[20:45] <Elwell> No whois server is known for this kind of object.
[20:45] <Darkside> Randomskk: that line is interesting
[20:45] <Darkside> does that mean stuff like hentai, etc, isn't illegal?
[20:45] <Randomskk> Elwell: read the register recently?
[20:45] <Randomskk> Darkside: hentai itself isn't illegal but never really was
[20:45] <Elwell> Randomskk: aye - thats where I got the URL
[20:45] <Randomskk> though lolicon is now illegal!
[20:45] <hibby> It's the bit in brackets after d that terrifies me.
[20:45] <Randomskk> eroomde: talking about illegal porn apparently
[20:46] <Darkside> yep
[20:46] <Darkside> it started as a discussion on ponies
[20:46] <Darkside> then it somehow moved through rule34 to illegal porn
[20:46] <Randomskk> Darkside: I think the thing people didn't like about the new laws is how things that are actually consensual and not harming anyone, but look like it, are now illegal
[20:46] <Randomskk> like if you got some fake blood, that would make it illegal
[20:46] <hibby> HAHAH
[20:46] <hibby> buggery is illegal
[20:46] <hibby> https://secure.wikimedia.org/wikipedia/en/wiki/Buggery
[20:46] <Randomskk> even though the thing itself was legal, the photo of it isn't. unless you were the person in the photo.
[20:46] <hibby> I didn't even know it was a thing
[20:47] <Randomskk> why are we even talking about this
[20:47] <Darkside> http://www.youtube.com/watch?v=dyrAkwJ6WsY <--- PONIES

[20:48] <Randomskk> I feel sullied, dirty and unusual. :|
[20:48] <Darkside> though i admit pinkies 'no fear' song is growing on me
[20:48] <Darkside> and the voice actors in MLP:FiM have INCREDIBLE singing voices
[20:49] <hibby> Yeah, I haven't noticed much in the way of autotune
[20:49] <hibby> which is unusual in kiddies tv these days
[20:49] <Darkside> mm
[20:49] <Darkside> dammit, now i'm watching ep 2 again to listen to pinkies song
[20:50] <eroomde> when is dr who?
[20:50] <eroomde> last sat or this?
[20:50] <Darkside> i thought it was september
[20:50] <hibby> last saturday of teh month I think
[20:50] <eroomde> damn
[20:50] <hibby> I remember being annoyed it was just before I returned
[20:50] <Randomskk> it's in my calendar as 27th aug
[20:50] <hibby> Matt Smith was on Craig Ferguson
[20:50] <Darkside> aww

[20:52] <eroomde> i just have a cheese sense of irennet
[20:52] <eroomde> (tenuous but I like it)
[20:52] <Darkside> ok applejacks singing voice isnt the best

[20:53] <Darkside> awesome track is awesome
[20:54] <hibby> they just you should have bit.ly'd that
[20:54] <Darkside> true
[20:54] <eroomde> has anyone seen that film that was made famous when it was randomly selected to be on the front page of imdb?
[20:54] <Darkside> still an awesome osng
[20:54] <hibby> uh, no?
[20:54] <eroomde> it's become a bit of a cult classic and is the most bizarre thing i have ever watched, without question
[20:55] <SpeedEvil> I wonder how much you have to pay to be randomly selected
[20:55] <fsphil> oddest thing I've watched lately was a french film called Immortal
[20:55] <hibby> It needs to be about 20% cooler.
[20:55] <eroomde> it's name is very subtle and doesn't give many clues to the contents, you might just gloss over it on a sunday afternoon tv schedule
[20:55] <Darkside> hibby: 10 seconds flat?
[20:55] <hibby> dressmaking
[20:55] <eroomde> it's called (brace yourselves): Gay Nigger from Outer Space
[20:55] <eroomde> Niggers*
[20:55] <fsphil> !!
[20:55] <Darkside> ohhhhhhhhhh
[20:55] <Darkside> that one
[20:55] <hibby> I've seen the advert
[20:55] <Darkside> GNAA
[20:55] <SpeedEvil> Is it about global warming?
[20:56] <Darkside> there was a shock site claiming to be the gay niggers association of amaerica
[20:56] <Darkside> america*
[20:56] <hibby> hahah
[20:56] <hibby> i remember that
[20:56] <Darkside> and they had their infamous 'last measure', which was a massive shock site
[20:56] <eroomde> it's about 20 minutes long, and is about alientas trying to make a homosexual society
[20:56] <Darkside> the one that turned up your PCs volume and shouted "I'm LOOKING AT CAY PORNO"
[20:56] <Darkside> gay*
[20:56] <Darkside> argh
[20:56] <eroomde> the first 10 minutes are quite inexplicably in black and white
[20:57] <Darkside> another hillarious song: http://lapfox.bandcamp.com/track/got-my-pony-spam-for-you

[20:57] <Darkside> hibby: this one is a mix of pinkies song, at the gala, and applejack is a silly pony
[20:57] <fsphil> have you people spiked my internet? searching for derezzed mixes on youtube and a bunch of pony stuff came up :p
[20:57] <hibby> banter
[20:57] <Darkside> fsphil: bahahahahahaha
[20:57] <Darkside> hibby: s/ban/can/
[20:58] <hibby> fsphil: glitch mob mix?
[20:58] <Darkside> fsphil: seriously, this is what has happened

[20:58] <eroomde> my friend has just been made a college byfellow because of all the teaching he's doing
[20:58] <Darkside> he got a shout out on an official video too :D
[20:58] <eroomde> he googled for 'bifellow' to see what it entialed
[20:58] <hibby> fsphil: wow.
[20:58] <eroomde> he was shocked
[20:59] <Darkside> fsphil: hasbro know about teh fans

[21:01] <Lunar_Lander> Laurenceb_ I am thinking the same
[21:01] <Darkside> Laurenceb_: we're talking about ponies
[21:02] <Laurenceb_> pony girl... is that like tubgirl
[21:02] <Darkside> and its perectly safe for work :P
[21:02] <fsphil> oh man it even looks like david tennant

[21:04] <Darkside> Lunar_Lander: its AWESOME

[21:05] <eroomde> Darkside: flux fumes or bath beer?
[21:05] <hibby> however the artwork on the fontpage of his site is somewhat reminiscent of the traditional furry style that pops up on the intarwebz
[21:05] <Darkside> hibby: thats because the artist is a furry
[21:06] <Darkside> i got over it after listening to a few of his tracks
[21:06] <hibby> I'd already drawn that conclusion
[21:06] <hibby> anthology: wow.

[21:37] <GW8RAK> Evening. Has anyone use Virtual Box at all please?
[21:37] <GW8RAK> used
[21:37] <Lunar_Lander> hello GW8RAK
[21:37] <fsphil> ah, I installed that for the first time today
[21:37] <GW8RAK> Evening Lunar_Lander
[21:37] <fsphil> installed Centos and Windows 95
[21:37] <Lunar_Lander> I posted the question at the chemistry forum
[21:38] <Lunar_Lander> the whole day no one answered
[21:38] <eroomde> GW8RAK: i use vb quite a lot
[21:38] <Elwell> ditto
[21:38] <eroomde> with vagrant which is a wonderful tool
[21:38] <GW8RAK> I have some motorola handhelds to program and they require a slow pc, typically IBM XT or AT level. A friend suggested Virtual Box and set up a virtual machine as a 8086 or 80286.
[21:39] <fsphil> old pc probably, rather than a slow one
[21:39] <GW8RAK> I've installed it and set up a virtual machine, but can't see anywhere to specify the processor/speed
[21:39] <fsphil> the software for MS-DOS?
[21:39] <GW8RAK> Any ideas?
[21:39] <GW8RAK> Yes DOS
[21:39] <GW8RAK> Hopefully someone will come up with an answer Lunar_Lander
[21:40] <fsphil> DOS should run in virtual box regardless of the processor
[21:40] <hibby> might be better getting qemu and working up?
[21:40] <Lunar_Lander> I hope so too GW8RAK
[21:40] <fsphil> try telling virtual box that the machine is for windows 95 -- same sort of specs of a typical high-end DOS machine of the day
[21:40] <Elwell> take it software needs real com1/com2 ports?
[21:41] <GW8RAK> Haven't heard of that one hibby, but just Googling
[21:41] <GW8RAK> I've got real Com ports. The problem is that the radios don't respond very quickly, so a fast pc just doesn't do it.
[21:42] <fsphil> oh
[21:42] <GW8RAK> Most commercial radio programmers have got an old XT in the corner of the workshop specifically for doing this task.
[21:42] <fsphil> qemu or virtual box can control the level of CPU, but I don't think they've any options to throttle the speed
[21:42] <Elwell> qemu might
[21:43] <GW8RAK> I know my son has played with it a lot, but he's buggered off to Afghanistan for 4 months.
[21:43] <GW8RAK> Kids! They let you down just when you need them.
[21:44] <fsphil> "A crash has occured in gnome-shell"
[21:44] <fsphil> well that's very nice

[21:48] <GW8RAK> Don't know fsphil. Just reading about qemu. Will download and try it if virtual box doesn't do it.
[21:48] <fsphil> someone made a patch: http://www.miroslavnovak.com/qemu-brake_en.php
[21:49] <fsphil> but I'm not sure if it's included
[21:49] <GW8RAK> Was looking on ebay for an old machine. Someone has a pre DOS Amstrad machine for £75!
[21:49] <fsphil> eek
[21:49] <fsphil> an amstrad that still works
[21:49] <GW8RAK> Complete with GEM OS

[21:53] <GW8RAK> Just found Dosbox which may also do what I want. Loads of options and loads of reading to do.

[22:35] <Darkside> aww it'll require changes
[22:35] <fsphil> hmms.. I've lost my usb extension
[22:35] <Darkside> thats annoyinh
[22:35] <NigelMoby> Oh that's by me to, its err.. mainly retail complex and a marina

[22:35] <fsphil> "beware: captain jack"
[22:35] <NigelMoby> That to :p
[22:36] <Darkside> sorry, am a nerd :P
[22:36] <NigelMoby> If we launch from penarth we can stop off and show you around the bay.
[22:37] <Darkside> cool
[22:37] <Darkside> where were you planning on launching from?
[22:38] <NigelMoby> Got 2 places in mind. Penarth or cosmeston lake.
[22:38] <NigelMoby> Could launch it off penarth pier, that'd b fun..
[22:39] <Darkside> lol
[22:39] <Darkside> yes
[22:39] <Darkside> wheres the predictions putting it?
[22:39] <NigelMoby> Between hereford and chepstow
[22:39] <NigelMoby> Keeps changing
[22:40] <Darkside> oh jeez
[22:40] <Darkside> i saw launch the other side of cardiff then
[22:40] <Darkside> the north-east side
[22:40] <Darkside> then immediately get onthe A40 and buck it up to monmouth
[22:40] <Darkside> or to a hill aroud there

[22:41] <Darkside> then track until we see it start descending, then go to the landing site
[22:42] <NigelMoby> Ahh, we can find some nice hills not far from the city, bout 20 min drive and we're 300m asl
[22:42] <Darkside> sorry, M4
[22:42] <Darkside> yeah, but we'll want to be heading up towards chepstow way
[22:42] <Darkside> else you'll loose the payload too quickly
[22:43] <Darkside> do you have any magmount antennas?
[22:43] <NigelMoby> No, just the Yagi and whip for the 790
[22:43] <Darkside> hmm ok
[22:43] <Darkside> i could always hold the cross-dipole out a window >_>
[22:44] <NigelMoby> Hah look a bit odd but y not, just don't drop it lol
[22:44] <Darkside> yep
[22:44] <Darkside> well, i could probably wedge it in the window quite well
[22:44] <Darkside> actually my supervisor said he had a few magmounts
[22:44] <NigelMoby> If it splashes down, happy swimming :p
[22:44] <Darkside> i'll get him to bring one in
[22:45] <NigelMoby> Awsome
[22:45] <Darkside> i'll have to make up a 1/4 wave whip for it
[22:45] <Darkside> anyway, i'd say launch from north-east of cardiff, and follow it best we can
[22:46] <Darkside> while getting to a high point would work, at teh heights it'll be getting to, it'll be moving quite fast
[22:46] <NigelMoby> Will have a look tomoz, just gotta be careful of powerlines
[22:46] <Darkside> and we should probably try and keep pace with it else we'll loose the payload
[22:46] <Darkside> what kind of ascent rate will it get?
[22:47] <NigelMoby> I'm gonna say 2.5 but it may b 3 if we get lucky
[22:47] <Darkside> if its fast enough, launch from the middle of roald dahl place :d
[22:47] <Darkside> :D
[22:47] <Darkside> you coudl just claim they were party ballons
[22:47] <Darkside> :P
[22:48] <NigelMoby> If I could be certain it'd clear the roof I'd launch from the garden lol
[22:48] <Darkside> heh
[22:49] <NigelMoby> Meh police choppers out
[22:49] <Darkside> so, what time should i be at cardiff central?
[22:49] <NigelMoby> 10am?

[22:51] <NigelMoby> Umm good question
[22:51] <Darkside> the flight is predicted to be 1 hr

[22:51] <Darkside> or descends slowly
[22:51] <NigelMoby> Yeah if it floats it could b up for hours
