[01:58] <saadzmirza> Hello! This is Saad Mirza, project manager of Marathon to the Sky.
[01:59] <saadzmirza> Our test launch #1 used a 1983 Kaysam 1200g Military Surplus Balloon. We were beaconing to Spacenear.us, and we were aiming for 31km. We got to 3.7km
[02:00] <saadzmirza> Our balloon appears to have sprung a leak, perhaps at the neck. The payload and balloon(appears to be solid, not shredded) about 70 feet up on a maple tree. The payload has the microSD for our 808. The property owner won't let us cut the tree down. Any ideas?

[02:12] <bbjunkie> saadzmirza - if it's close to the end of a branch, perhaps a quadcopter with a lifting hook?
[02:14] <zyp> and now you have both a quadrotor and a baloon payload stuck in a tree :)
[02:14] <bbjunkie> :)

[02:17] <zyp> I got my quadrotor stuck high up in a tree before
[02:18] <zyp> we had to go get a bunch of wood that we hooked together to make it long enough to reach up and nudge it down
[02:19] <zyp> long enough that we had to tether the end and have people pulling on the tethers to control it
[02:20] <bbjunkie> lol.. sounds like fun
[02:22] <zyp> it's fun to think back to at least :)
[02:23] <mightymik> try a line with a slingshot
[02:24] <zyp> we tried a bunch of throwing, without getting high/accurate enough
[02:27] <mightymik> there's a fishing line / slingshot combo that people use to put up wire antennas , worth a try

[09:32] <S_Mark> ping upu
[09:32] <daveake> I think he's busy today
[09:32] <daveake> tbh if you have a payload doc I wouldn't worry about it

[09:33] <jededu> Ahh ok diddnt know that it was approved friday but ran out
[09:34] <jededu> Could be low on trackers tho
[09:34] <daveake> The payload doc is enough to make it appear on the map; the flight doc just makes it easier for people to configure

[12:44] <daveake> Normally one is supplied with the tank

[12:52] <Htbrdd> what about the ones i have seen that are a hose and pvc tube?
[12:52] <mikestir_M0MKS> you make that and attach it to the supplied adapter with a hose clip
[12:53] <myier> anybody with fldigi opened can tell me which baud rates it proposes in the list, for RTTY?
[12:54] <mikestir_M0MKS> myier: loads. what did you have in mind?
[12:54] <myier> and has anybody tried to use faster modes than 50 in real hab conditions? how bad can it go?
[12:54] <Htbrdd> ah so that screws into the regulator?
[12:55] <mikestir_M0MKS> Htbrdd: the boc ones come with the combined reg/nozzle that daveake described. The end of the nozzle is just a tapered plastic bit like you'd get on a pump for blowing up an airbed
[12:55] <mikestir_M0MKS> so you just need some hose with suitable inside diameter that you can clamp onto it

[13:21] <maxmed> Hi, I'm new to HAB, does anyone know if there is any pre-written code available for connecting an arduino to U-blox MAX 7 and Radiometrix NTX2B?

[13:24] <daveake> The rest you do yourself
[13:24] ulfr (~ulfr@leynir.ulfr.net) joined #highaltitude.
[13:25] <on4bhm> maxmed: i'm writing the same code as you want
[13:25] <on4bhm> i'm also new at hab
[13:26] <on4bhm> my first steps into combination arduino mini + µblox7 + ntx2b
[13:26] <maxmed> I worked through that guide and got managed to get it to work but then wasnt sure how to make it send the gps data rather than just a test sentance?
[13:26] <on4bhm> i'm using the rtty code at the moment
[13:26] <daveake> Use snprintf
[13:26] <daveake> Standard C function
[13:27] <on4bhm> my first remark was: it takes here a very very long time to lock on gps signal
[13:27] <daveake> You also need to do a CRC calculation and you can get that code on the web too
[13:29] <on4bhm> problem with arduino mini is: it has only 1 serial port
[13:29] jededu__mob (5284d5b1@gateway/web/freenode/ip.82.132.213.177) left irc: Ping timeout: 246 seconds
[13:29] <on4bhm> so can't upload new version of code, while rx'ing data from gps
[13:30] <daveake> You can put a switch in the GPS Tx --> Arduino Rx line
[13:30] <daveake> Or use an AVR ISP
[13:30] <on4bhm> i know, now i'm using just stripped cables.... :(
[13:31] <maxmed> I tried using teh code here: http://www.ukhas.org.uk/guides:ublox6 which seemed to almost work but then when i received the signal i could not decode it as it had no carrier shift
[13:32] <daveake> Sorry that makes no sense. That code is for receiving data from the GPS. You then need to transmit data using code such as in the NTX2 example I gave to you.
[13:32] <daveake> If there's no carrier shift then your transmission code is wrong - nothing to do with the GPS at all
[13:34] <maxmed> ahh that makes sense! I'll try to combine them. I am able to understand most the code but get really confused when it comes to the checksums!
[13:34] <on4bhm> in the code maxmed's url: what does the initialization do?
[13:35] <on4bhm> checksum part was easy for me... gps code is more difficult here
[13:35] <daveake> tinygps does it for you
[13:35] <on4bhm> i'm using tinygps
[13:35] <daveake> the init code sets flight mode in the gps
[13:36] <on4bhm> is it absolutelty needed at ground level tests?
[13:36] <daveake> well it's not difficult at all - you feed it NMEA data a byte at a time, it tells you when it has a position, then you get the lat/long/etc
[13:36] <daveake> isn't needed at all for ground tests
[13:37] <daveake> just don't fly without it
[13:37] <on4bhm> ok will skip it for now
[13:37] <on4bhm> i understand the tinygps code... but the lock takes for ever!
[13:38] <mikestir_M0MKS> shouldn't take long if the gps has a good view of the sky
[13:38] <daveake> a) get it near a window b) make sure the gps has a good power supply (the 3V3 line on Arduino does NOT count as good for this)
[13:38] <on4bhm> newData triggers all the time. but lon and lat are ??'s
[13:39] <on4bhm> it's laying with lipo 3.7v 1000mAh in the middle of my garden
[13:39] <daveake> Most Arduinos have a 3V3 line rated for 50mA only; a Ublox can use double that before it gets a lock
[13:40] <mikestir_M0MKS> how big is your garden? on the ground in a built up area doesn't really count as a good view of the sky, depending on the time of day
[13:40] <daveake> 3.7V connected to what?
[13:45] <maxmed> so i shouldn't connect teh ublox to the VCC pin on an arduino pro mini 3.3v?
[13:47] <on4bhm> i connected the µblox now directly to the lipo
[13:47] <on4bhm> i'll wait and see what happens
[13:48] <mikestir_M0MKS> eek no don't do that
[13:48] <on4bhm> when i use my diode test on my meter, the vcc of mini arduino is connected to vcc where lipo is connected
[13:48] <on4bhm> m0mks why not?
[13:49] <mikestir_M0MKS> lipo is 3.7V
[13:49] <on4bhm> can't it handle 3.7?
[13:49] <mikestir_M0MKS> I'm just checking but I imagine it's 3.6V absolute max, and you shouldn't be running it even at that
[13:50] <maxmed> so do i just use the "NTX2 example" and replace the "RTTY TEST BEACON RTTY TEST BEACON" with GPS.read()
[13:50] <mikestir_M0MKS> yes 3.6v absolute max, so you shouldn't be running it on anything higher than a regulated 3.3V rail

[14:24] <jcoxon> oh there are loads of flight computer code online
[14:24] <jcoxon> on most peoples githubs
[14:26] <maxmed> ahh, I see. My problem is that although i have a basic understanding of arduino code, most the stuff in the examples is just beyond me and makes no real sense. its hard to patch the codes together when you dont understand what each bit does. I'll have a look on Github
[14:27] <jcoxon> maxmed, the trick is to break it down
[14:27] <jcoxon> so get rtty working
[14:27] <jcoxon> then get the gps working
[14:27] <jcoxon> then put them together
[14:28] <mikestir_M0MKS> and if you don't understand what part of some code is doing then ask. You're far more likely to get a positive result if you ask what a couple of specific lines of C do, than if you say "this blob of code I got off github doesn't work, why?"

[20:11] <olegrc> hi all. i have a question. If a balloon with 3 gr freelift & 15gr payload floats at aproximate 8000m without problem, and descends slowly at midnight, and goes up to 8000m again after sunrise, what is the problem?
[20:12] <mfa298> sounds like your problem is the sun
[20:12] <olegrc> i need more or less helium
[20:12] <olegrc> ?
[20:13] <daveake> you need more or less helium to do what?
[20:13] <mfa298> it went down as the balloon cooled (no solar heating) and then went back up when it warmed up again. Sounds about right unless you want to change the rules of physics.
[20:15] <Upu> gas warms up
[20:15] <LeoBodnar> sounds like nps with balloon
[20:15] <Upu> the latex balloons do it as well
[20:15] <LeoBodnar> do you have an altitude profile picture?
[20:15] <Upu> generally drop over night, then climb in the morning before bursting
[20:15] <myier> Upu: when you talk about power saving code in your PAVA R7 article, what exactly are you talking about? Using interrupts and deeper sleep modes, or disabling input/outputs, or both or what?

[20:16] SpeedEvil (~quassel@tor/regular/SpeedEvil) left irc: Ping timeout: 245 seconds
[20:16] <myier> I've seen the GPS power mode, but in the MCU part, what is there exactly?
[20:16] <Upu> myier no basically putting the GPS in 1 second cyclic mode
[20:16] <Upu> and thats about it
[20:17] olegrc (51160dea@gateway/web/freenode/ip.81.22.13.234) left irc: Ping timeout: 246 seconds
[20:17] <myier> nobody tried to use timer interrupts to drive the RTTY transmission instead of the delayMicroseconds?
[20:17] <Upu> oh I would always use interupts
[20:17] <myier> (and powering down between the interrupts)
[20:17] <Upu> yeah you can do
[20:17] <daveake> I think most people user timers for that
[20:17] <Upu> however traditionally with drifty radios powering down was a bad idea
[20:17] <Upu> as people would loose the signal
[20:17] <myier> ok, because the example code on the ukhas website seems quite power hungry
[20:18] <Upu> however with the newer radios that have TCXO's you can get away with it
[20:18] <Upu> its the hardware using the power not the code :)
[20:19] <Upu> what radio are you using ?
[20:19] <myier> I wasn't able to find a clear answer as to what does the delayMicroseconds function do, but I guess it doesn't involve any power modes?
[20:19] <myier> NTX2
[20:20] <Upu> no
[20:20] <daveake> nothing to do with ntx2
[20:20] <daveake> and no it does no power saving
[20:20] <Upu> all that does is provide the timing for the RTTY
[20:20] <daveake> and there's no point either
[20:20] <Upu> if you go back it explains how we get the timing for 50 baud
[20:20] <daveake> gps uses >> power than radio >> CPU
[20:21] <Upu> yeah as daveake says the GPS is your largest user of power
[20:21] <myier> yes
[20:21] <myier> ok
[20:21] <Upu> but the NTX2B is never going to win any power contests anyway as it doen't run at lower voltages
[20:21] <Upu> if you're new to this I'd make a tracker based around that and a GPS and not worry about power
[20:22] <Upu> as long as it lasts 8 hours or more from some batteries you are good
[20:22] <Lunar_Lander> is there a pronounced diurnal cycle of temperature at altitude?
[20:22] <Lunar_Lander> i.e. a big difference between day and night
[20:22] Action: Upu goes and googles diurnal
[20:23] <mfa298> myier: I think the idea of what's on the wiki is to give a starting point for absolute beginners to start with that's (hopefully) easy to understand. Once people get happier with how the stuff works they can look at powersaving and other customisations for what they want the payload to do.
[20:23] <myier> yes
[20:23] <myier> it's easy
[20:23] SpeedEvil (~quassel@tor/regular/SpeedEvil) joined #highaltitude.
[20:23] <myier> ok thanks Upu and dave
[20:24] <myier> I'll try at least to get the GPS power savings described in the R7 article
[20:25] <daveake> If you haven't already, get a basic tracker running first without any power saving
[20:25] SiC (~Simon@cpc12-aztw24-2-0-cust193.aztw.cable.virginm.net) joined #highaltitude.
[20:25] <daveake> and unless you're doing a floater, you don't need power saving at all
[20:26] <myier> I've not looked at the uBlox protocol yet, but is there a way to have a 0.2Hz update rate for it? Since the RTTY takes some time to transmit, there may be no need to update it very often?
[20:27] <myier> yes I have daveake, almost. I have a timing issue in the code that makes the baud rate not very accurate, that's why I was thinking about timers and power savings while I was at it
[20:27] slobber (linkxs@unaffiliated/linkxs) left irc: Ping timeout: 240 seconds
[20:27] <daveake> Just use timer interrupts for the rtty. The end.
[20:27] <myier> no that won't be a floater, and indeed I probably don't need any power saving, that's just for the beauty of it
[20:28] <daveake> Forget power saving unless you need it, and do GPS saving first
[20:28] <myier> ok
[20:28] <daveake> CPU power usage is tiny in comparison
[20:28] <myier> understood

[20:28] <myier> just to be sure, the timer interrupts for RTTY, is it delayMicroseconds or hand made intrrupts that you're talking about?

[20:30] <daveake> The Arduino delay routines do NOT use interrupts
[20:30] <daveake> Do it yourself --- set up the timer dividers etc and write an ISR

[20:45] <mfa298> originally they were allocated in order

[20:50] Nick change: SpaceBaron -> LeoBodnar
[20:50] <mfa298> In someways I'm surprised the 2E0's have so few at the start of the range allocated seeing as it had been around for longer than M0, although the old Novice (which is what the 2E range was) wasn't the most useful license (although the class B 2E1 was worse)
[20:51] <mikestir_M0MKS> was 2E0 used first? I thought the old novice licence was 2E1?
[20:51] <astrobiologist> how do the numbers compare between foundation, intermediate and full?
[20:51] <mfa298> 2E1 for class B, 2E0 for Class A (or that's what I thought it was)
[20:51] <mfa298> although I suspect not many did the Class A novice.
[20:52] <mikestir_M0MKS> oh right. I didn't realise they had two classes of novice as well.
[20:52] <astrobiologist> it seems to me that if you don't have a garden for a wire antenna, and don't have access to a roof, then there isn't much point in going beyond foundation
[20:52] <mfa298> I'm pretty sure there was (might need to check the old folder of stuff)
[20:53] <mfa298> astrobiologist: there were some numbers during the rsgb consultation consulation thing. I think it was something like intermediate was around 1/2 of foundation, and full was 1/2 intermediate.
[20:53] <astrobiologist> I am only doing it looking to the long term to allow ham use for tracking payloads abroad (if fly again from black rock) or for airborne APRS if that is allowed here

[20:54] <astrobiologist> mfa298: at least that means there is fresh blood incoming then
[20:54] <daveake> Well one reason I did it is that if rules are relaxed to allow airborne use, it might be for full only. Also with full you can use the licence abroad.

[20:54] <astrobiologist> daveake: same again, haven't really learnt anything new in at least ten years
[20:58] <LazyLeopard> Foundation was a start, but Intermediate was just a step to Full, and only Full allowed for the possibility of operating overseas...
[20:59] <LazyLeopard> Never used my Intermediate call on-air.
[20:59] <daveake> Never used any call on-air
[20:59] <Upu> yet..

[21:00] <Upu> I did
[21:00] <Upu> they can do that as long as you pass the Foundation
[21:00] <astrobiologist> I find the whole thing to be in dire straits in terms of the number of people on air

[21:05] <mfa298> from memory last year we only managed to make contact with those already in the building when we were almost there. although that was 817 to 817.
[21:05] <Upu> yeah will try this year
[21:05] <LazyLeopard> ...with the rubber duck antennas?
[21:05] <Reb-SM0ULC> mfa298: it's full duplex but the uplink is compressed? ;)
[21:06] <Upu> I have a proper hand held now
[21:06] <Upu> my 817 lasted about 20 mins on battery last year
[21:06] <mfa298> I had a magmount on the car but I think Upu was using the rubber duck in the building.
[21:06] <Upu> I was
[21:06] <Upu> I have a VX-8G with an SRH815S antenna now
[21:07] <mfa298> a dipole to stick out the window might be worth while (although I can't remember how openable the windows were.
[21:07] <chrisstubbs> Bad things might happen if I stick a magmount on the roof of the train on the way down
[21:07] <Upu> don't suspect it will go any further but it will last longer than 20 mins on battery
[21:08] <Upu> (its been on for 15 hours doing APRS over the last 2 days and is still reporting full battery)
[21:08] <astrobiologist> I shall vanquish you with my th-f7e on battery which lasts literally about 9 hours at least
[21:08] <mfa298> In theory I should be able to beat that, with my th-f7e and it's spare battery :p
[21:09] <astrobiologist> spare batteries are cheating
[21:09] <Upu> I do have the larger battery
[21:09] <astrobiologist> just bring a cartload why don't you

[21:10] <astrobiologist> you can have SDR transmitter thought
[21:10] <Upu> you can but try carrying it around to the top of a hill
[21:11] <mfa298> what we really need is Kenwood to do a version of the 817, it'll be better and you'll be able to actually change stuff safely when driving.
[21:11] Action: mfa298 really hates the yaesu menu system they seem to have on all their radios
[21:11] <Upu> you get used to it
[21:12] <Upu> Leo likes the menu system on the VX
[21:12] <astrobiologist> too much crammed on to the th-f7e one
[21:13] <mfa298> I like having a radio where I can turn useful things on and off with a simple push button rather than the push a button, twiddle something,try and decode a cryptic 2 letter code for function name, press more buttons and then maybe you'll have turned it on.
[21:14] <astrobiologist> sounds like you need one of those handhelds which only has preset channels. but then you need to remember how to set the channels!
[21:15] <mfa298> I was going to use the examples of changing the ssb bandwidth or noise reduction but then realised the 817 doesn't have such features.
[21:15] <mfa298> I was actually thinking of something a bit smaller than the TS-2000
[21:16] <mfa298> most of the useful stuff is on the numeric keypad

[21:21] <mfa298> he was around earlier
[21:22] <astrobiologist> thanks, I'll drop him a note

[21:31] <astrobiologist> just finished the intermediate license practical assessments - they seem totally random in what they are trying to assess

[21:42] <Ian_> Maybe they are trying to assess if you recognise random when you see it in action!
[21:44] <Ian_> It's also like Boelle_DK doesn't understand fully the concept of getting a tracker launched from one country to another with pretty near 100% success rate - I understand that Upu does it in his little boxes almost daily :)
[21:45] <Lunar_Lander> :)
[21:49] <Ian_> So, there is a list of hotels for the Conference, but which ones will people be staying at. I guess that I will have to travel down Friday evening and am in two minds if to travel back to the West Mids late Saturday evening or Sunday morning.
[21:49] <Upu> I'm in Novotel Greenwich
[21:49] <Upu> and going back on Sunday
[21:50] <mikestir_M0MKS> I was thinking of coming and just getting the train down on the day, but the west coast mainline is shut for engineering works
[21:52] <Upu> going to close registrations soon
[21:52] <Ian_> Sounds like a reasonable plan. I think that getting up at sparrow fart to get to Greenwich for 10am is asking for sleepy eyes and a stressed brain. Then rushing back woud miss the informal communication opertunities.
[21:52] <Upu> so if you are considering comig you need to get your tickets soon please
[21:53] <mikestir_M0MKS> well so far I haven't come up with alternative travel arrangements that don't involve sleeping on the platform at birmingham new street and/or spending £250 on hotels

[21:53] <Ian_> I have been trying to convince a pal of mine to come, but he's heging his bets and seems unlikely.
[21:53] <mikestir_M0MKS> normally it would be the 0645 from liverpool to get into london before 9
[21:54] <mfa298> Ian_: based on what craag managed last year there are no excuses although at least he didn't have to drive up.
[21:54] Nick change: mikestir_M0MKS -> mikestir
[21:55] <Ian_> I think that it's expensive on travel and hotels, but if I say it quickly and spend it fast, then it's gone and I don't expect that I'll feel the pain for too long.
[21:56] <Ian_> Maybe I'll try to flog you all stocks of honey to give to farmers with your trackers on the barn roof. :)
[21:56] <Lunar_Lander> xD
[21:57] <mfa298> if there's 2 or three people from the same place then driving potentially becomes the cheaper option (even with london parking). Although I don't know how that works if you're doing an over night (I only looked at daytime parking last year)
[21:58] <Ian_> No, Lunar_Lander, the xD was what I think I did when I didn't put my boots on when visiting a large colony of bees the other day. Just a quick visti. Two boxes off, two empty ones and a clearer board on. Put the two boxes on the floor and all the stings that weren't in my shoes were in my ankles - not a happy drive home.
[22:00] <Lunar_Lander> ouch!
[22:00] <fsphil> understatement
[22:02] <Ian_> You don't get the luxury of running away when the job needs done and the damage is underway. If necessary shut your eyes (if they are on the inside) and get on with it as quickly as possible.
[22:02] <Ian_> The reward is around 300lb of a summer harvest.
[22:02] <Ian_> Just a hobby . . . :)
[22:03] <gonzo__> that sounds more like the site safety course for the nuclear sites!
[22:03] <Ian_> It felt quite different gonzo__

[22:04] <gonzo__> the suiting up is similar
[22:04] <Ian_> No sign of the onset of arthritis of course. I bet the radiation suit is hotter than a beesuit too.
[22:05] <gonzo__> luckilly I never worked in the areas needing the mitchelin man suits. Just paper oversuits etc
[22:06] <Ian_> Would that make you an Alpha male?
[22:07] <gonzo__> nope, just beta'n up
[22:08] <Ian_> If I remember correctly (doubtfull) Water would protect you from gamma rays, but convert it to neutron s. Makes you wonder about a good drop of persperation.
[22:08] <Lunar_Lander> gammas don't really produce neutrons in water
[22:08] <gonzo__> good managenemt means you don't get that much of a dose
[22:08] <gonzo__> for that to nbe an issue
[22:08] <Lunar_Lander> you get neutrons from the fission of the Uranium for instance
[22:09] <gonzo__> they do store the used fuel in a big tank, caled the core pond
[22:09] <Lunar_Lander> the gammas rather ionize atoms in the matter and then you either get another gamma from the photoelectric effect, or compton interaction or pair formation above 1 MeV
[22:10] <gonzo__> I was involved in monitoiring it, not making it!
[22:10] <Ian_> If it's likely to glow in the dark I tend to want to stay away. I only got into bees because you get to handle naked girls in boxes - seemed attractive at the time!
[22:11] <Ian_> It's great conversation starter! Honest
[22:12] <mfa298> much more fun to make people think you're drinking something radio active by drinking G&T under UV lights. It glows nicely :)
[22:12] <Lunar_Lander> xD
[22:12] <Ian_> Gotta have Angustura Bitters too
[22:14] <mfa298> Random film trivia - the Cherenkov effect in "K-19: The widow Maker" was from Tonic water and UV lights.
[22:15] <gonzo__> they didn't have gin? Missed a trick there
[22:15] <gonzo__> just have a can of old speckled hen here
[22:15] <mfa298> I assume the Gin was kept to be drunk rather than wasted on special effects.
[22:16] <Ian_> I have a funny story about gin - ask me at the Conference or afterwards. All a bit retrospective though.
[22:17] <Lunar_Lander> good night!
[22:17] <LazyLeopard> ...while Tonic Water is not much use for anything else, so can't be considered wasted on a special effect. ;)
[22:17] <Ian_> Good night Lunar_Lander
