[00:57] <arko> anyone know what the average line of sight is at 30,000m?
[00:57] <arko> im getting about 370 miles
[00:58] <arko> (yeah my units are all sorts of bad)
[00:58] <Darkside> 714km
[00:58] <arko> woah
[00:58] <Darkside> according to http://www.calculatoredge.com/electronics/lineofsight.htm
[00:59] <arko> cool
[00:59] <arko> ball park is close enough
[00:59] <arko> that's some crazy coverage
[00:59] <Darkside> this is why you need to be careful with APRS
[01:00] <arko> why so?
[01:00] <Darkside> as you're going hit a LOT of digipeaters and igates
[01:00] <arko> oh
[01:00] <arko> IM GOING 35W
[01:00] <arko> lets hit New York
[01:00] <Darkside> ducting!
[01:00] <arko> seriously though, whats the problem?
[01:00] <Darkside> hit ALL the digi's
[01:00] <Darkside> congestion on the network
[01:00] <arko> oh
[01:01] <Darkside> if you use a bad path (i.e. one with a high ttl), your packet is going to be bounced all around the network multiple times
[01:01] <Darkside> which is bad
[01:01] <arko> yeah
[01:01] <arko> any recommended antennas?
[01:01] <arko> ground and payload?
[01:01] <arko> also orientation
[01:01] <Darkside> for 2m?
[01:02] <arko> yeah
[01:02] <Darkside> well, we use handheld whip antennas, mounted in a similar cofiguration to the 1/4 wave antennas you've probably seen
[01:03] <arko> does your payload antenna point upsidedown? to the side?
[01:03] <arko> right side up?
[01:03] <Darkside> points down
[01:03] <arko> is that the right way to do it?
[01:04] <arko> are whip antennas omni?
[01:04] <meatmanek> whip antennas are somewhat planar
[01:04] <Darkside> http://projecthorus.org/wp-content/uploads/2012/04/pMNZN.jpg
[01:04] <Darkside> you can see it in the left of that pic
[01:04] <Darkside> still trying to find a better picture,
[01:04] <Darkside> but that's a Comet SMA-24 handheld antenna
[01:05] <meatmanek> pointing down, with a ground plane, is a pretty good way to do it.
[01:05] <Darkside> if you *really* want range, then you could fly a jpole or slim jim or something
[01:05] <Darkside> but it's probably best to limit the damage :-)
[01:05] <arko> yeah
[01:05] <arko> i need to find the radiation pattern
[01:06] <meatmanek> I mean, if you're using a really short path, you're probably ok.
[01:06] <arko> i thought whip are donuts
[01:06] <meatmanek> dipole is a donut
[01:06] <arko> oh
[01:06] <arko> what about whip?
[01:06] <meatmanek> whip with a groundplane is a slightly conical donut, if that makes any sense
[01:06] <arko> here's what would suck, being right under it and getting nothing
[01:06] <arko> that does
[01:07] <Darkside> at 300mW you shoudl be fine
[01:07] <meatmanek> ground plane reflects downward radiation upwards (or vice-versa when flipped)
[01:07] <Darkside> but yes, when you are directly under the payload you willg et less signal
[01:07] <arko> ok
[01:07] <Darkside> unless you fly some kind of hemispherically radiating antenna, which is impractical at 2m
[01:07] <arko> do i have to tune the ground plane?
[01:07] <Darkside> no
[01:07] <meatmanek> it just has to be big enough
[01:07] <arko> does it effect the resonance?
[01:08] <arko> ok
[01:08] <Darkside> arko: nah, not really
[01:08] <arko> gonna have to figure it out for 2m
[01:08] <Darkside> the ground plane on our aprs payload is not actually 1/4 wave in size
[01:08] <Darkside> its a lot smaller
[01:08] <Darkside> but it works
[01:08] <meatmanek> anyway yeah I did APRS with a pretty aggressive path. Probably congested the network more than I should have
[01:08] <Darkside> all it will do is modify the radiation pattern of the antenna
[01:08] <arko> cool
[01:08] <meatmanek> also was sending beacons at a much higher rate than I should have
[01:08] <Darkside> meatmanek: how fast? we do 30 seconds
[01:08] <arko> haha
[01:08] <Darkside> >_>
[01:08] <meatmanek> we did like 10s I believe
[01:08] <Darkside> oh dear
[01:09] <meatmanek> yeah.
[01:09] <Darkside> thats nasty
[01:09] <Darkside> we only fly aprs as a backup system
[01:09] <meatmanek> first time doing anything on APRS
[01:09] <Darkside> we always use 70cm rtty as our primary
[01:09] <Darkside> as we can transmit at a very high rate
[01:09] <Darkside> we usually do one update every 4 second using 300 baud rtty
[01:10] <meatmanek> I should research rtty more
[01:10] <Darkside> it works very well
[01:11] <Darkside> and with less tx power
[01:11] <meatmanek> how much power do you use?
[01:12] <Darkside> 25mW
[01:13] <Darkside> the UK guys use 10mW, but they mostly fly 50 baud
[01:13] <Darkside> we prefer 300 baud
[01:13] <meatmanek> yeah
[01:14] <meatmanek> have you played with the SSDV stuff that i think fsphil made?

[03:03] <SpeedEvil> yeah, these were people carrying ones
[03:20] <heathkid> okay
[03:21] <heathkid> using a standard 36" parashoot to slow things down after burst... at what altitude is there enough "air" for a paraglider?
[03:21] <heathkid> since I've never done this before I'm guessing the parashoot acts like a streamer until there is enough "air" anyway... right?
[03:23] G8KNN-Jon (~Jon@cpc1-cmbg10-0-0-cust144.5-4.cable.virginmedia.com) joined #highaltitude.
[03:23] <meatmanek> you mean enough air for a pararchute to actually deploy?
[03:26] <heathkid> yes
[03:27] <meatmanek> no idea.
[03:28] <heathkid> sorry I keep mis-spelling parachute but it's late and it's been a long week... :)
[03:28] <heathkid> I have no idea either
[03:28] <heathkid> anyone here?
[03:29] <heathkid> surely someone has data on descent rate that would give a clue to when the parachute opened fully....
[03:34] <SpeedEvil> it's complex
[03:34] <SpeedEvil> for chutes like that, it may fold or knot in the low pressure
[03:35] <heathkid> a descent rate of 5m/s is about 11 MPH (right at the limit for a small paraglider without tearing it apart)
[03:35] <heathkid> like I said.... a two stage descent
[03:35] <SpeedEvil> missed that
[03:36] <heathkid> parachute to slow it down... then drop the actual payload via paraglider
[03:36] <SpeedEvil> Laurenceb has done rollago
[03:36] <heathkid> from what I've read... they come pre-tangled up... lol
[03:36] <SpeedEvil> rogallo
[03:36] <heathkid> I'd prefer not to have that happen
[03:37] <heathkid> rogallo?
[03:37] <SpeedEvil> the easy way is wires to keep it open
[03:37] <SpeedEvil> http://en.m.wikipedia.org/wiki/Rogallo_wing
[03:49] <heathkid> oh, this gets very complicated VERY fast!
[03:51] <meatmanek> why a paraglider, anyway?
[03:51] <heathkid> why not?
[03:51] <meatmanek> aren't paragliders incredibly slow and inefficient?
[03:51] <heathkid> no
[03:51] <meatmanek> they seem not very aerodynamic
[03:51] <heathkid> they can fly like a glider using thermals and such... and have control over direction
[03:52] <heathkid> http://en.wikipedia.org/wiki/Paraglider
[03:53] <heathkid> most parachutes these days are based on this design
[03:53] <heathkid> well.... not the plain round type
[03:53] <meatmanek> I guess when I say efficiency I mean glide ration
[03:54] <meatmanek> glide ratio*
[03:54] <heathkid> wikipedia: The glide ratio of paragliders ranges from 8.8 for recreational wings, to about 11.0 for modern competition models.[16] For comparison, a typical skydiving parachute will achieve about 3:1 glide. A hang glider ranges from 11.0 for recreational wings, to about 17.0 for modern competition models. An idling (gliding) Cessna 152 light aircraft will achieve 9:1.
[03:55] <meatmanek> hm.
[03:55] <heathkid> so better than a Cessna...
[03:55] <SpeedEvil> and 'proper' gliders can hit 40
[04:07] <heathkid> think of it this way... with a quick ascent minimal float high-altitude balloon launch... it may be possible using a two stage descent (parachute then paraglider) to return the payload to the launch site.
[04:08] <heathkid> in theory
[04:09] <heathkid> the paraglider can be conrolled using as little as one servo
[04:09] <heathkid> though I'd probably use at least two
[04:09] <heathkid> my 600g Kaymont isn't going to cut it for a first launch though... so this is still just "dreaming"
[04:10] <heathkid> though the paraglider linked to will support up to about 1.5Kg
[04:12] <heathkid> no one has tried this before?

[07:58] <daveake> Sky is pretty
[08:00] <Elwell> right you folks - Slightly OT but figured you folks have played with the relevant hardware anyway. I've just hooked up a DS18B20 temp sensor to a R-Pi running the octover raspbian - works fine with bitbanging, but feels slow when reading /sys/bus/w1/devices/28-0000044aeaab/w1_slave -- would this be any faster if I use a proper 1-wire master (DS2482-100)?
[08:00] <Elwell> or are these things just 'slow' at the best of times?
[08:01] <daveake> The speed depends on the resolution you request
[08:01] <daveake> So probably it's asking for lots of bits
[08:01] <Elwell> aah OK - to the nearest 0.5 degrees is plenty - I guess asking for the whole thing via /sys is greedy
[08:01] <daveake> Do you have a means of changing that? In my trackers I only request 9 bits which is a resolution of about 1 degree
[08:02] <Elwell> not yet, but I can do ....
[08:02] <daveake> 12 bits is over a second IIRC

[11:42] <costyn> ah
[11:42] <Darkside> there'll probably be a 10.7MHz IF
[11:42] <Darkside> though not always
[11:42] <gonzo___> intermediate frequency
[11:43] <costyn> thx

[11:43] <gonzo___> the radio (a superhetrodyne type) will convert the incoming freqs to a common IF freq, then the rest of the radio works at that freq

[11:44] <costyn> I forsee a floater in our future
[11:45] <Darkside> costyn: its so underinflated the drag will be quite high
[11:45] <costyn> Darkside: which means?
[11:45] <Darkside> these launches always seem to be slow at the start, then speed up as the balloon fills out
[11:45] <costyn> ah
[11:46] <Vortex> just got a carryier on 345.222
[11:46] <Darkside> ok guys, whats the actual frequency on the balloon
[11:46] <mattbrejza> try 195
[11:46] <Darkside> so i can change the tracker page
[11:46] <mattbrejza> well it is 195
[11:47] <mattbrejza> well 196
[11:47] <mattbrejza> but yea
[11:47] <Darkside> so whats the deal with the 2 callsigns?
[11:47] <Darkside> is it just broadcasting a different callsign for the differnt gps data?
[11:47] <Upu_M0UPU> qava = adafruit gps
[11:47] <Upu_M0UPU> pava = ublox
[11:47] <Darkside> k, frequency on the page changed

[11:58] <NickB1> that would be great :)
[11:59] <costyn> Maxell and I want to set up an antenna on the top of the building where our hackerspace is. coax would be too long to run to the space itself, so we need to put something up near the roof
[11:59] <Darkside> costyn: its too slow
[11:59] <costyn> Darkside: hmmm thought it might be
[11:59] <mattbrejza> just foerward the audio?
[11:59] <Darkside> well you coudl use a rtlsdr
[12:00] <Darkside> theres software to dump the data from teh rtlsdr over the network
[12:00] <Darkside> the raw IQ that is - the pi is fast enough to do that
[12:00] <costyn> cool
[12:00] <Darkside> then you do all the heavy duty SDR stuff on another machine

[12:03] <Darkside> might have a chat with you about that sometime
[12:03] <Upu> sure
[12:03] <Upu> Belgium
[12:03] <Upu> lol
[12:03] <Maxell> costyn: yeah, stream the audiosignal over the network. We even could use wifi for that.
[12:03] <Upu> well that wasn't predicted
[12:03] <Upu> oh well
[12:03] <Darkside> Maxell: i'd suggest using a rtlsdr and a habamp on the roof, plugged into a pi
[12:03] <Darkside> and stream the raw IQ data down via ethernet
[12:04] <Darkside> if you run ethernet up, you could power it vua ethernet too

[12:04] <Darkside> RG_LZ1DEV: adafruit logo
[12:04] <costyn> RG_LZ1DEV: Adafruit logo
[12:04] <NickB1> does the pi have PoE ?
[12:04] <RG_LZ1DEV> oh
[12:04] <Darkside> NickB1: no
[12:04] <Darkside> but not hard to rig up something to take powe off the spare pairs in CAT6
[12:04] <Darkside> or CAT5,e, whatever
[12:05] <NickB1> indeed
[12:05] <NickB1> they sell seperatoe PoE modules to
[12:05] <Darkside> mm
[12:05] <costyn> Darkside: sounds good, thanks for the suggestions
[12:05] <Darkside> but yeah, the idea being that the pi only shovels data from USB onto the network
[12:05] <Darkside> it doesn't do any more processing - it isn't fast enough to do that
[12:06] <RG_LZ1DEV> can the network handle that much traffic?
[12:06] <x-f> costyn, you just need a permanent ssh access to the rpi then - rtl_tcp crashes quite a lot
[12:06] <Darkside> RG_LZ1DEV: yeah
[12:06] <g7ogxchris> my friend g4ztq in chichester is hearing the signal for 11 seconds every 5 seconds 5/9
[12:06] <Darkside> RG_LZ1DEV: it'll be 3MB/s or so

[13:24] <Darkside> fsphil: that won't give you a frquency shift

[13:24] <daveake> Adafruit module (QAVA) now past the 27km point (it's a mod to their previous one that only went up to 27jm)
[13:24] <jdtanner> I can make out something very weak...
[13:24] <fsphil> Darkside: not a frequency shift, not sure what that's about
[13:24] guest67832 (1f3464d7@gateway/web/freenode/ip. joined #highaltitude.
[13:24] <Darkside> fsphil: you don't get multipath *that* bad through the troposphere
[13:24] <jdtanner> Normally receiver is fine for more "local" flights ;)
[13:24] <fsphil> the effect I mean is where it appears quite strong nera the horizon, then weakens just above it
[13:24] <chrisg7ogx> heard it before similar on hf when conditions are good long path and short path heard at same time but withe delay
[13:25] <Darkside> oh
[13:25] <Darkside> fsphil: antenna gain pattern?
[13:25] <Upu_M0UPU> ok looks like the Adafruit fixed the 27km issue
[13:25] <fsphil> possible, although the degrees above my horizon should be tiny
[13:26] <Darkside> its also possible it's just fading due to weird ducting
[13:26] <fsphil> it always happens
[13:26] <fsphil> upu's seen the same effect
[13:26] <Darkside> mm, probably weird propagation due to ducting then
[13:26] <Darkside> modeling that kind of propagation is a bitch
[13:26] <chrisg7ogx> degrees tiny at your qth but massive at balloon
[13:26] <fsphil> yea
[13:27] <junderwood_M0JCU> ground speed seems to be rather high.
[13:27] <junderwood_M0JCU> Signal is changing frequency as well.
[13:27] <chrisg7ogx> heard the story about yanks boming japan and discovering high altitude winds/
[13:28] <fsphil> wasn't it the other way around?
[13:28] <chrisg7ogx> yes getting qsb during transmission now didn't send up pink bunny with duracell/
[13:29] <chrisg7ogx> talking aboutB29s arriving over Japan much earlier than predicted and accuracy unexpectedly poor
[13:30] <chrisg7ogx> yurp to ducting getting wavering of traces on my waterfall
[13:30] <fsphil> the frequency drifting is normal
[13:31] <jdtanner> partial decodes now
[13:31] <fsphil> it's an effect of temperature on the radio module
[13:31] <Upu_M0UPU> its been pretty stable th
[13:31] <Upu_M0UPU> tbh
[13:31] <chrisg7ogx> is it temperature or just inaccuracy of unit/
[13:31] <fsphil> it is
[13:31] <fsphil> temperature of the crystal
[13:32] <chrisg7ogx> have to walk puppy back later this is compulsive stuff
[13:32] <fsphil> dogs are so much better than cats

[13:35] <fsphil> ah brilliant
[13:36] <Darkside> i do hope you land in france :-)
[13:36] <Darkside> you might get the payload back
[13:36] <daveake> if it does land in France they won't know what it is - maybe they'll eat it?

[13:44] <costyn> Darkside: thats silly
[13:44] <Darkside> thats the point i decided it would be a good time to cut down the payload
[13:44] <Upu_M0UPU> Adafruit GPS is on Software serial
[13:44] <costyn> ludicrous speed
[13:44] <Upu_M0UPU> so the code generally ignores it if it takes too long to respond
[13:44] <costyn> Upu_M0UPU: are they both on the same microcontroller?
[13:44] <Upu_M0UPU> yes
[13:45] <costyn> ah neat
[13:45] <junderwood_M0JCU> So it's supposed to be alternate packets
[13:45] <Upu_M0UPU> yeah it waits 1 sec for something from the Adafruit, if it doesn't get anything it just moves on
[13:45] <Upu_M0UPU> notice if don't get a QAVA there is a long delay between next TX
[13:46] <costyn> seriously those french guys should go pick it up... only a 20 min. drive for them

[14:29] <scobla> and have many questions
[14:29] <scobla> first
[14:29] <Upu_M0UPU> free payload all you need is 1 boat
[14:29] <daveake> OK, though not sure "soon" is compatible with "many questions" :)
[14:29] <costyn> daveake: hahaha well said
[14:30] <scobla> is habhub acurate on landing direction and distance?
[14:30] <scobla> like how close is going to be
[14:30] <Darkside> if your inputs are accurate, it's pretty good
[14:30] <daveake> Pretty close, if you give it the right numbers
[14:30] <Darkside> gets better the closer to the launch date
[14:30] <costyn> scobla: it's pretty good. I saw my payload come falling out of the sky by driving to the predicted landing spot
[14:31] <daveake> Mostly the error is that the fill is not what you told it
[14:31] <scobla> the fill!!! you mean the balloon fill?
[14:31] <daveake> Yes
[14:31] <Darkside> what dave said - you'll only get that flight path if you ascend at the rate you told the predictor you would, and burst when you told it you would
[14:31] <scobla> this tkes us to m next question
[14:31] <daveake> Obviously you have to put in the right amount according to the weight of your payload. So measure everything
[14:31] <scobla> how to get the right ampunt of fill?
[14:32] <Darkside> if you want to get it dead on, fill in a big shed

[14:32] <daveake> Calculate here http://www.cusf.co.uk/calc/
[14:32] <Darkside> and use some form of scales yto measure the nexk lift
[14:32] <scobla> am using the kaymont 1200g
[14:32] <Darkside> you can use fish scales to measure the upwards force
[14:32] <scobla> payload around 4 lbs
[14:33] <scobla> is a jack of water more usefull?
[14:33] <F5APQ> last point 50.98549,1.02396
[14:33] <Darkside> scobla: thats the other way of doin git
[14:33] <Darkside> fill a bottle of water to the required neck lift weight
[14:33] <Darkside> and fill until you get neutral buoyancy
[14:33] Gadget-Mac (~swp@ joined #highaltitude.
[14:34] <scobla> how much free lift is best for 100 kft and higher?
[14:34] <Darkside> depends on your payload weight
[14:34] <Darkside> you can use the calculator to figure out what you need
[14:34] <scobla> lets say 4 lbs
[14:34] <scobla> ok '
[14:34] <costyn> F5APQ: cool... only 3.5KM from shore
[14:34] <Darkside> whats that in real units
[14:34] <costyn> Darkside: 1.8kg
[14:34] <scobla> now, how about tieing the balloon tot he robe?
[14:35] <Darkside> scobla: cable ties
[14:35] <Darkside> and duct tape
[14:35] <scobla> i have no idea on how to do it
[14:35] <Darkside> hold on
[14:35] <Darkside> i have video!
[14:35] <costyn> scobla: http://ukhas.org.uk/guides:sealing_the_balloon?s[]=neck

[14:35] <costyn> scobla: where are you from?
[14:35] <scobla> saudi

[14:36] <Darkside> http://vimeo.com/46031355
[14:36] <Darkside> theres some video of us tying off the balloon in there
[14:36] <scobla> yeah, i will be the forst hab in my region
[14:36] <Darkside> scobla: what are you using for tracking?
[14:36] <scobla> SPOT
[14:36] <scobla> only SPOT
[14:36] <Darkside> heh
[14:37] <Darkside> well, set it to update as often as it can, and you should be ok
[14:37] <costyn> was expecting GSM :)
[14:37] <Darkside> but i'd reccomend something else
[14:37] <Darkside> well, in addition to spot
[14:37] <scobla> GSM lol

[14:37] <scobla> likw what
[14:37] <costyn> scobla: that's the correct answer :)
[14:37] <Darkside> if you land upside down you're not going to get any messages back from the tracker
[14:38] <scobla> i have solved that issue by building a gimbal
[14:38] <Darkside> heh
[14:38] <Darkside> depends what you land on
[14:38] <costyn> interesting
[14:38] <Darkside> you could land in a tree
[14:38] <Darkside> or in soft sand
[14:38] <Darkside> or something
[14:38] <Darkside> i dunno
[14:38] <costyn> Darkside: probably sand
[14:38] <Darkside> we like radio trackers here
[14:38] <scobla> gimball should take that issue out of my mind
[14:39] <Darkside> as worse case scenario you can use direction finding techniques to locate it
[14:39] <Darkside> scobla: something else, the gps in a spot tracker will give otu above a vertain altitude
[14:39] <Darkside> certain*
[14:39] <Darkside> i think it'll lose lock at 60000ft - can anyone confirm this?

[14:39] <scobla> lose track at 30 k
[14:40] <scobla> confirmed
[14:40] <Darkside> hopefully it will regain lock on the way back down
[14:41] <scobla> i am concerned about filling the balloon and tieing it without burting or something
[14:41] <Darkside> but it means you won't have any positioning for a significant portion of your flight
[14:41] <scobla> yeah i won't
[14:41] <Darkside> again, this is why we use radio telemetry
[14:41] <Darkside> we have position information for the entire flight
[14:41] <costyn> scobla: the neck of the balloon is pretty tough
[14:41] <Darkside> and fast updates of position too - in my case every 4 seconds
[14:42] <scobla> by the second flight i will have learnt something about radio telemetry
[14:42] <scobla> it is nuclear science to mee at the moment
[14:42] <scobla> lo
[14:42] <scobla> lol
[14:42] <gonzo___> what was the final resting place for q/pava ?
[14:42] <Darkside> scobla: it's not too hard

[14:58] <scobla> what does 2417 g neck lift mean?
[14:58] <scobla> and how can i achieve it?

[14:59] <Dutch-Mill> Grr audio not working,...
[14:59] <costyn> scobla: keep filling your balloon with helium until it starts lifting this amount of weight
[14:59] <craag> Dutch-Mil: Not for me either

[15:03] <scobla> how do i know the maximum altitude reached ?
[15:04] <scobla> what is the simplest way
[15:04] <costyn> scobla: gps tracker
[15:04] <costyn> scobla: if you're not going to use the radio method
[15:04] <costyn> i mean, a gps logger

[15:11] <scobla> no gps will work above 60 k
[15:11] <scobla> i know this for a fact
[15:12] <costyn> scobla: KM or 60000ft?
[15:12] <scobla> ft
[15:12] <costyn> scobla: some do, the ublox chipsets we use work just fine
[15:13] <scobla> are u talking about logger or real time tracker?
[15:13] <costyn> scobla: just the GPS chip
[15:13] <Darkside> this is the gps chip itself
[15:13] <Darkside> which we use in our trackers
[15:13] <scobla> ok
[15:14] <Darkside> the problem is, even if you could find a logger with a ublox chip built in, it would likely not work anyway
[15:14] <Darkside> as the ublox chip has to be put into a special mode to work above 18km
[15:14] <scobla> ok
[15:15] <Darkside> i believe there are other loggers out there that would work, i just don't know which ones
[15:15] <Darkside> as i've never used them
[15:15] <Darkside> i only use real-time radio tracking
[15:17] <scobla> ok
[15:18] <scobla> what is the minumum horizental landing distance i should expect in lets say a quite day
[15:18] <costyn> scobla: alternatively if you don't want to do radio tracking you could make a microcontroller based logger using a ublox chipset, but if you go that far, you might as well do radio tracking
[15:18] <costyn> scobla: well the winds at altitude have no relation to those on the ground, so it's hard to say
[15:19] <costyn> scobla: try running the habhub predictor on some different days and see what you get for your location
[15:19] <scobla> what is the sjortest distanc ein your experience?
[15:19] <Darkside> scobla: shortest i've ever had is 10km
[15:19] <Darkside> but that was not normal
[15:19] <Darkside> regular distance for our launches is around 150km
[15:20] <scobla> i have ran many habhub predictions and they all came out above 100 km
[15:20] <Darkside> longest was about 1120km
[15:20] <Darkside> yeah, that sounds about normal
[15:20] <costyn> scobla: yes 100km can be expected
[15:20] <scobla> i actually want ot to be that far to avoid landing in a difficult area
[15:20] <Darkside> landing away from populated areas is usually a good idea
[15:21] <scobla> 1120km wow
[15:21] <costyn> scobla: you mean far out in the desert?
[15:21] <scobla> i might as well check ticket prices on expedia haha

[15:22] <scobla> what is the best time to lauch during the day?
[15:22] <Darkside> morning
[15:22] <costyn> scobla: the morning, so you have the rest of the day to chase it
[15:22] <scobla> i am looking for a quite time
[15:22] <Darkside> just so you have as long as possible to recover it before it gets dark
[15:22] <scobla> like just after sun rise
[15:22] <Darkside> hunting in a field for a payload at nightime sucks
[15:22] <Darkside> scobla: we usually launch around 9-10am or so
[15:23] <costyn> scobla: a quiet time will make filling the balloon and measuring neck-lift easy, but won't matter for distance flown
[15:23] <scobla> what part of the world are u in?

[15:23] <Darkside> and me, in Australia :P
[15:23] <costyn> and we have our token Australian
[15:23] <scobla> i want a quite time so that the payload won't spinn much i.e better video
[15:24] <costyn> scobla: it will spin in any case
[15:24] <Darkside> usually they spin quite slowly anyway
[15:24] <Darkside> which looks good on video
[15:24] <costyn> scobla: although there are ways to make it spin less with adding some strategically placed foam weights on the end of a rod
[15:25] <Darkside> costyn: never worked for us lol
[15:25] <scobla> lol
[15:25] <Darkside> we've done some pretty scary things to try and make our video payloads spin less
[15:25] <Darkside> none worked

[15:32] <scobla> mine does not have one
[15:32] <costyn> there are other factors like the length of line between your balloon and parachute and parachute and payload which are more important (should be like 10m)

[15:37] <costyn> scobla: as far as I know you need a regulator meant for helium
[15:37] <scobla> why?
[15:38] <costyn> because the properties of the gasses are different. gas (propane) is a lot heavier
[15:38] <x-f> and may be different threads

[15:42] <gonzo___> not sure if different suppliers used a standard coupling eithwr. Anyone know the answer?

[15:43] <scobla> how many tanks is enough?

[15:43] <scobla> 1200g kaymont balloon
[15:43] <costyn> scobla: the calculator should tell you know many liters of gas you need
[15:44] <gonzo___> So I expect the filling may be different. As you would need more vol of mixed gas for the saame lift
[15:44] <costyn> gonzo___: yea apparently it's so kids (and/or idiots) don't asphyxiate themselves when playing (too much) with helium
[15:44] <scobla> i donlt think the regulator will have a meter on it

[15:45] <scobla> lasty thing i want to happen is run out of helium half wau through the filling process
[15:45] <costyn> scobla: yes, that would suck
[15:45] <costyn> scobla: does your He supplier have a website?
[15:45] <scobla> no
[15:45] <scobla> and they probably do not know how much helium is in a tank

[15:46] <Upu_M0UPU> hi Costyn
[15:46] <Upu_M0UPU> back now
[15:47] <gonzo___> probably a new counrty for us in this chan then!
[15:47] <costyn> Upu_M0UPU: hiya... scobla was wondering why you need specific helium regulators, but the question has already been answered somewhat
[15:47] <costyn> Upu_M0UPU: threads and bottle pressure and such
[15:47] <Upu_M0UPU> oh ok :)
[15:47] <scobla> i am new to hab that's why
[15:48] <scobla> nervi=ous on ahead of my first flight
[15:48] <Upu_M0UPU> we just went to recover Daves payload he put in a tree 12 months ago
[15:48] <Upu_M0UPU> no joy
[15:48] <x-f> using catapult and wire saw?
[15:48] <JFS1> Missed the end of PAVA/QAVA flight - any chance of getting them out of the Channel?
[15:48] <costyn> Upu_M0UPU: for shits & giggles? :) I assume ther's not much left to recover?
[15:48] <gonzo___> still up there?
[15:48] <scobla> payload sitting in a tree for 12 months?
[15:49] <costyn> scobla: yea, we have a lot of tree landings in this part of the world :)
[15:49] <scobla> but 12 months is somewhat frustrating?
[15:49] <gonzo___> I have seen a design for a catapult with a fishing line reel fixed on it, for getting lines into trees. (advert on qrz.com ?)
[15:49] <scobla> is it that difficult to get it down?
[15:49] <scobla> rent a tree trim service
[15:49] <costyn> scobla: if it's 15 meters up in a tree, yes

[15:50] <costyn> no, we make our own

[15:53] <costyn> yea
[15:53] <scobla> back to attaching a water jack to the neck method of filling
[15:54] <scobla> how much of a lift tot he jack is enough?
[15:54] <scobla> i heard just enough to lift it a little bit and float
[15:54] <costyn> scobla: correct
[15:54] <costyn> scobla: should just hover
[15:54] <scobla> ok
[15:54] <scobla> interesting
[15:55] <costyn> scobla: which is why it is nice to do it when there's no wind, otherwise it starts acting as a sail
[15:55] <costyn> and the wind pulls on your balloon
[15:56] <scobla> so if i get a perfect filling as per the calculator i should expect to reach optimal altitude?
[15:56] <costyn> scobla: yes, what did you fill in? ascent speed or expected altitude?
[15:57] <x-f> the tracking information for tomorrow's flight has been posted even in Yahoo FUNcube's mailing list, along with all the chat, UKHAS, BATC and spacenear.us links

[15:59] <scobla> 1814 g
[16:00] <scobla> how on earth am gona know if the tank has that much of helium on my first launch
[16:01] <scobla> i will rent 2 tanks and get it out of my head

[16:02] <costyn> scobla: maybe if you go by your supplier and take some pictures and show us we can see how big they are and if they're likely to have enough
[16:02] <scobla> that would be very nice of you guys
[16:03] <scobla> getting more than i bargined for

[16:03] <scobla> how about when i am done filing the balloon!!! how do i get around tieing the neck?

[16:50] <G7PMO_Kev> Guys, could someone work through these calcs for me and check they look right, especially the final additional neck weight - ie how much my coke bottle tied to the filling adapter needs to weigh? :)
[16:50] <G7PMO_Kev> 500g Balloon, 600g payload all in, needs a neck lift of 1.23kg to achieve an ascent rate of 4.9m/s, which will give a burst altitude of 26,488 Meters, after 90 mins. It will need 1.7m3 of Helium. My filling adapter, with 40cm of hose, weighs 0.35kg, therefore my additional neck weight to judge free lift for launch needs to be 1.23kg - 0.35kg = 0.88kg
[16:50] <G7PMO_Kev> any comments much appreciated :)

[22:01] <Lunar_Lander> hello DrLuke

[22:01] <RG_LZ1DEV> thats second to getting hit on the head by a small meteorite
[22:01] <DrLuke> but that's what the insurance is for
[22:01] <Lunar_Lander> yes
[22:02] <gonzo___> I thought it was to make profits for insurance companies?
[22:04] <jdtanner> Evening. Don't suppose any of you have a Fritzing "part" for the NTX2?
[22:07] <griffonbot> Received email: James Coxon "Re: [UKHAS] Re: Insurance Working Group"
