[06:27] <SA6BSS-Mike> hopefully it will start sending backlogs so we can se actual route
[06:27] <LeoBodnar> hope so
[06:27] <arko> well its still july 20 here
[06:28] <arko> woah these B's have backlogs?
[06:28] <LeoBodnar> yeah 5 days' worth
[06:28] <arko> that's brilliant!
[06:28] <LeoBodnar> not much but enough to roughly estimate the rest with NOAA
[06:28] <DL7AD> WOW!
[06:28] <arko> i was about to go to sleep then i switched over to the tab and it refeshed
[06:29] <arko> if it makes it back to the UK you get a cake
[06:29] <LeoBodnar> just when B-64 and B-66 were basking in the limelight
[06:29] <arko> phase lag yo!
[06:29] <LeoBodnar> take the backstreet route yo
[06:29] <arko> haha
[06:30] <arko> i love the sine waves
[06:30] <DL7AD> omg the tracker seems to have an error
[06:30] <LeoBodnar> i suspect B-63 made a loop over Siberia
[06:31] <DL7AD> it did probably

[07:46] <fsphil> looks like it's been doing circles in northern russia
[07:46] <craag> incredible
[07:47] <F1VJQ> What's the news on real position of B-63? My map shows it in Alaska!
[07:47] <Trieste> fsphil: B-63?
[07:47] <fsphil> Trieste: yep
[07:47] <Trieste> aw :(
[07:47] <craag> F1VJQ: Yep :D
[07:47] <fsphil> that explains why it vanished for so long
[07:47] <LeoBodnar> i think it did Arctic challenege on the way too
[07:47] <F1VJQ> The only problem is the map tracks it back eastwards (not long path hihi),
[07:48] <Trieste> fsphil: oh wait, I thought that meant that the data is wrong and is still in russia - that's great then!
[07:48] <F1VJQ> B-64 could reappear having passed south of Kamchatka yesterday early hours
[07:48] <LeoBodnar> F1VJQ: http://habitat.habhub.org/mobile-tracker/?filter=B-63
[07:49] <craag> leaflet doesn't seem to handle cross-pacific paths well
[07:49] <fsphil> that's the one bit that's working on spacenear
[07:49] <Trieste> what was specific about B-63 that it fared so well?
[07:49] <LeoBodnar> it had 62 before it
[07:50] <Trieste> oh :)

[07:51] <LeoBodnar> reverse fsphil challenge?
[07:51] <F1VJQ> craag it crossed the International dateline, so probably went back to yesterday!!
[07:51] <fsphil> lol
[07:51] <fsphil> exactly
[07:51] <LeoBodnar> conference logo needs Mk.II
[07:52] <F1VJQ> craag ...or tomorrow!
[07:52] <craag> F1VJQ: Heh yes
[07:54] <craag> Hmm looks like I need to add in some date-line crossing detection and manually tell leaflet to wrap it
[07:54] <F1VJQ> LeoBodnar I meant to ask if you have a selection of APRS freq in your CPU? US uses different ones from Eu and Africa
[07:55] <F1VJQ> Canada may use different one from USA too
[07:55] <KT5TK> No, Canada is on 144.390 like the US
[07:56] <F1VJQ> KT5TK OK thanks ... 144.800 in Eu and Africa
[07:57] <LeoBodnar> F1VJQ: i have used this as a reference http://aprsisce.wdfiles.com/local--files/doc:frequencies/APRSVHFworldmap.png
[07:57] <KT5TK> Yes, Leo switches APRS frequencies according to position
[07:58] <F1VJQ> LeoBodnar That's the map I looked at re B-64 - wondered if B-64 will cross Pacific too by tomorrow?
[07:58] <UpuWork> probably not
[07:58] <UpuWork> it wasn't going quickly enough but it may get close to Hawaii
[07:58] <DL7AD> no
[07:58] <LeoBodnar> it was in a very slow moving airmass when it left Japan
[07:58] <DL7AD> will take about two weeks

[08:09] <F1VJQ> lz1dev OK loaded it now... message on top says "THIS ISN'T WORKING PLEASE USE HTTP://HABHUB.ORG/MT INSTEAD" probably shouldn't

[08:12] <lz1dev> one of it's methods hangs

[08:15] <F1VJQ> UpuWork OK
[08:18] <F1VJQ> Looks OK now
[08:20] <F1VJQ> Map shows no 434MHz ears in NA
[08:21] <fsphil> I don't believe it's transmitting on 70cm over NA
[08:21] <lz1dev> is that north korea
[08:21] <lz1dev> for APRS not permitted
[08:22] <F1VJQ> I meant NA = North America
[08:22] <lz1dev> yes yes, im looking at http://aprsisce.wdfiles.com/local--files/doc:frequencies/APRSVHFworldmap.png
[08:23] <F1VJQ> I don't think there is much of anything permitted there!!
[08:24] <lz1dev> this makes me wonder, why not have one frequency for aprs
[08:24] <fsphil> that would make too much sense
[08:24] <lz1dev> i guess the argument is that they already ahve all their equipment on X frequency
[08:25] <fsphil> it would be easier to make an aprs2, and require it in a certain frequency
[08:27] <lz1dev> i don't think that is possible
[08:27] <lz1dev> people won't move
[08:27] <fsphil> yep
[08:27] <fsphil> sad but true
[08:27] <lz1dev> just like IPv6
[08:27] <fsphil> that is slowly increasing in use
[08:28] <fsphil> I knew it was beginning to become popular when I saw the first IPv6 spam email getting rejected
[08:28] <lz1dev> they kind of have to
[08:29] <F1VJQ> lz1dev standards would be nice .... starting with razor blades.. it would be good if they all fitted my razor
[08:30] <F1VJQ> every 2/3/4/5 blade thing doesn't fit any of the others.... what nonsense
[08:30] <lz1dev> but thats not how you locking customers to yourself
[08:30] <F1VJQ> I don't like lockins... so I don't go down that route...
[08:31] <lz1dev> after all apple can sell you an usb cable for a small fortune
[08:31] <F1VJQ> I like universal blades
[08:31] <lz1dev> even thought its UNIVERSAL serial buss
[08:31] <F1VJQ> one size fits all...

[10:18] <astrobiologist> same here
[10:18] <gonzo__> you are getting all poetic. Not a good sign in an engineer
[10:19] <astrobiologist> quick, someone look up the full quote

[10:19] Action: SpeedEvil looked up a full quote once. In the rain.
[10:20] <fsphil> the battery in my Nexus lasts about as long as those in the film
[10:21] <astrobiologist> I've... seen things you people wouldn't believe... Attack ships on fire off the shoulder of Orion. I watched c-beams glitter in the dark near the Tannhäuser Gate. All those... moments... will be lost in time, like [small cough] tears... in... rain. Time... to die...
[10:25] <astrobiologist> it is entirely possible that Leo's balloons will have a longer life expectancy that the fictional replicants in "Blade Runner"! I mean, will they ever come down? Dan Bowen said the early "Ghost" balloons sometimes circled the world for several years before finally failing
[10:25] <fsphil> yea some of them did
[10:26] <SpeedEvil> The current balloons all seem to have fairly short lives.
[10:26] <SpeedEvil> Best case is a few weeks IIRC - due to helium diffusion
[10:26] <SpeedEvil> (which is awesome, admittedly)
[10:26] <fsphil> larger balloon and thicker material needed maybe
[10:26] <fsphil> hydrogen would help
[10:27] Action: SpeedEvil raises his foil balloon idea again.
[10:28] <astrobiologist> I need to get into custom balloons for my project... probably PE for ease of handling and heat crimping
[10:28] <fsphil> I've a few foils in storage. Wonder if they improve with age? :)
[10:29] <astrobiologist> basically I need to spray the exterior down with peroxide in flight... thinking of a buckminster-fuller type envelope with one sprayer at each vertice
[10:31] <astrobiologist> that way I can scale up in size with a standard basic panel design

[10:59] <astrobiologist> but how do I get the peroxide all over the balloon? It seemed unlikely to me that it would run all over the balloon envelope
[11:00] <SpeedEvil> You're trying to sterilise the envelope?
[11:01] <astrobiologist> I had assumed I would have one sprayer per vertice (could be a 1ml syringe or similar) but then maybe a roller cage or similar to keep the sprayed vertice topmost for a while, then move on to the next one, and so on
[11:01] <SpeedEvil> Latex is not going to work - you'll need something peroxide compatible
[11:01] <SpeedEvil> why are you trying to sterilise the envelope, versus having - say - the payload on a 100m string

[11:01] <astrobiologist> SpeedEvil yes I'm trying to sterilise it, assuming I will use PE
[11:01] <astrobiologist> SpeedEvil the envelope and the string have to be assumed to be sources of contamination
[11:02] <astrobiologist> Otherwise how to disprove the null hypothesis? (i.e bugs found at altitude are just bits of crap you brought with you)
[11:03] <SpeedEvil> Sterilising 200m of string in flight, then deploying seems _way_ easier
[11:03] <astrobiologist> SpeedEvil but you still have to assume that there is crap floating down from the envelope, especially during ascent

[11:13] <fsphil> not a thing
[11:13] <fsphil> other than potentially breaking
[11:13] <fsphil> probably won't break but you never know what libc is up to

[12:15] <maxmed> Its says "TinyGPS" does not name a type
[12:16] <maxmed> the "nss" was not declared in this scope
[12:16] <mikestir-work> first error implies your #include is wrong
[12:16] <mikestir-work> and the second one is because nss isn't declare anywhere
[12:17] <mikestir-work> declared*
[12:17] <maxmed> so at the satrt i have to put "int nss; " ?
[12:17] <mikestir-work> well no, because it looks like it's supposed to be a software serial object
[12:18] <maxmed> oh i see, what if I dont want a software serial but a hardware serial?
[12:19] <mikestir-work> I know nothing about arduino, but presumably they wrap that up in some other object that you can declare

[15:05] <maxmed_> ok, my tracking code now compiles fine suggesting i have fixed all the bugs. i think the spacing is still a bit messed up but finding it quite hard to follow whats happening so I'll leave it as it is for now. Code is here: https://github.com/Max-Med/tracking_code_5/commit/1bb74735fe89b18230c95aa738871329d435dbe3 can anyone see any problems before I upload it which could damgae my equiptment?
[15:05] <maxmed_> *damage
[15:08] <qyx_> your equipment should never be damaged by code
[15:08] <qyx_> or at least it should be designed that way
[15:09] <qyx_> btw line 64 will cause checksum_str overflow
[15:09] <bertrik> maxmed_: I highly recommend 'cppcheck' as a basic check of your code
[15:09] <bertrik> [tracking.cpp:61]: (error) sprintf format string requires 7 parameters but only 5 are given.
[15:09] <bertrik> [tracking.cpp:64]: (error) Buffer is accessed out of bounds.
[15:09] <mikestir-work> qyx_: that bug is on the wiki - I actually got as far as creating a wiki account to fix it yesterday but I still need to get write access
[15:09] <mattbrejza> well you could set a pin to an output that should only be an input
[15:10] <qyx_> and general feeling - mess :)
[15:12] <Maxell> mattbrejza: yes and without current limiting resistors in line... oef!
[15:18] <mikestir-work> so to summarise maxmed_, char checksum_str[6] should really be char checksum_str[7]. and you aren't passing enough things to sprintf(datastring,...)
[15:19] <mikestir-work> the format string probably wants to be changed to "%f,%f,%d,%f,%f" to fix that
[15:21] <mikestir-work> and you should really use snprintf rather than sprintf. This is exactly the same but it contrains the output so that it won't ever overflow your buffer. You would use it (in this case) like snprintf(datastring, sizeof(datastring), "%f,%f... and same for the checksum_str one
[15:21] <maxmed_> is there an easy was to add a callsign to the sprintf ?
[15:22] <mikestir-work> yes just write it at the front of the format string, e.g. CALLSIGN,%f,%f,%d
[15:23] <maxmed_> sorry to be a bit thick but what do i put in after snprintf for sizeof(datastring) ?
[15:23] <amell> Man walked on the moon 45 years ago today.
[15:24] <amell> Might be useful for HABs, if someone can find a uC that runs this assembly& Apollo Lunar module flight computer source code is at http://www.ibiblio.org/apollo/listings/Comanche055/ lol
[15:24] <mikestir-work> maxmed_: you can literally write sizeof(datastring)
[15:24] <fsphil> there has been nobody on the moon my entire life. this is not good enough
[15:25] <mikestir-work> sizeof is a C keyword, and since datastring is an array of known size the compiler will figure out the right number for you
[15:25] Action: amell is not surprised that apollo computer simulators exist that can run this code.
[15:26] <mikestir-work> isn't there one in MESS?
[15:26] <mikestir-work> and I'm sure I saw someone did one on an fpga
[15:29] <maxmed_> Thnaks mikestri-work that is really helpful, thank you for your patience! here is corrected code: https://github.com/Max-Med/tracking_code_6/commit/26f7dc2425788df182b4fca381ac3bf469866e68 hopefully it will work.

[15:45] <maxmed_> mikestir-work it seems to sort of work, i havent got a gps lock yet but it seems to be transmitting. the signal wanders a bit and often seems corrupted but not sure why that is
[15:45] <amell> I think we might need to work out B-63 distance flown using a modified vincenty formula.
[15:46] <maxmed_> is the problem that i forgot to add the new line command on the end of the datastring?
[15:48] <mikestir-work> no, because that's correctly added with the checksum

[15:53] <amell> looking into this. im not sure great circle distance makes any sense for leos flight as its broken all the assumptions. What about rhumb line distance instead? would arhab accept that?
[15:54] <edmoore> i'd just do distance along the path, surely
[15:54] <amell> but what is the path defined as&
[15:54] <edmoore> the path
[15:54] <edmoore> recorded points
[15:55] <edmoore> <= actual path
[15:55] <edmoore> so you can't exaggerate
[15:55] <amell> okay. could do it that way, but what about the loops, disregard?
[15:55] <edmoore> unless two consecutive points are >0.5d apart
[15:55] <edmoore> no, because if you disregard the loops then it's not the distance along the path
[15:55] <edmoore> it's some weird heuristicy thing
[15:56] <amell> dont see why you cant disregard the loops, seeing as it crosses its own path there.
[15:57] <edmoore> that's an arbitrary thing
[15:57] <amell> clearly, the CNSP record is now completely smashed, but how to calculate a comparative distance.
[15:57] <LeoBodnar> this might help http://www.fai.org/component/phocadownload/category/1029-around-the-world-flights?download=57:cia-around-the-world-flight-rules
[15:59] <maxmed_> mikestir-work - I've managed to get a gps lock, I'm now successfully receiving data so finally SUCCESS! although it is not transmitting my call sign "MAX" but instead "GPS" is the problem that there is no $$ at the start of the datastring?
[16:00] <edmoore> ok, so that's putting a dot every half-earth-radius and joining up the dots with straight lines and measuring that length
[16:01] <amell> define half-earth-radius
[16:02] <edmoore> average radius of the earth
[16:02] <edmoore> ... divided by two
[16:04] <amell> okay, theres enough info in that document to work it out. except it will take time to do.
[16:04] <edmoore> 10 minutes of python coding :)
[16:05] <amell> sure, dont have 10 mins right now.
[16:06] <mikestir-work> maxmed_: yes, but that doesn't explain why it's sending GPS instead of MAX!

[16:08] <SpeedEvil> One quick hack is to just work out distances from points days apart
[16:08] <SpeedEvil> at 24h intervals that is
[16:09] <edmoore> feels a bit unclean to use times to demark distances like that
[16:09] <maxmed_> wait so was the problem the lack of $$ or the fact that it doesnt send MAX ?

[16:38] <maxmed_> to remove the $$ could I use "char *c_MovedPtr = c_Array + 2;" where char *c is a new datastring?
[16:38] <aadamson> mikestir-work, hehe... yeah I know that feeling well! :)... good luck on all fronts :)
[16:39] <mikestir-work> maxmed_: exactly, but you can just do the +2 where you pass it to gps_CRC16_checksum
[16:43] <maxmed_> so i can just do: gps_CRC16_checksum(datastring +2); ?
[16:44] <mikestir-work> actually I just noticed that the 2 character offset is already handled in the gps_CRC16_checksum function, so you don't need to do that
[16:46] <mikestir-work> it's skipping the first two characters anyway
[16:46] <mikestir-work> but the answer to your question is yes
[16:49] <maxmed_> It seems like too big a co-incidence for the callsign to come through as GPS each time, it must be in the code somewhere but i cant find it anywhere

[17:08] <PC1PCL> The strcat() function appends the src string to the dest string, over writing the terminating null byte ('\0') at the end of dest, and then adds a terminating null byte. The strings may not overlap, and the dest string must have enough space for the result. If dest is not large enough, program behavior is unpredictable; buffer overruns are a
[17:08] <PC1PCL> favorite avnue for attacking secure programas.
[17:10] <PC1PCL> so, if the datastring buffer is large enough, strcat would be adding the checksum to the end, and a \n for a newline (actually a linefeed, so it might end up like a staircase if you print those strings to something that expect a carriage return too)

[17:16] <DL1SGP> Guten Abend Kevin
[17:16] <Lunar_Lander> hallo
[17:16] <Lunar_Lander> and hello
[17:16] <Lunar_Lander> and cogratulations LeoBodnar
[17:16] <maxmed_> PC1PCL here is the complete code :https://github.com/Max-Med/tracking_code_8/commit/ff1f3183b5741786033f25085436a9b53595bff1, I'm afraid i dont understand much of what you asked/said. how do i change the size of teh buffer and what is strchar
[17:17] <Lunar_Lander> protip: Buffer size is the number in the brackets like buffer[size]
[17:18] <PC1PCL> your datastring buffer is therefore 80 characters long, giving you 79 characters of useful string length and 1 character for the 'null' at the end

[17:20] <maxmed_> so should i change it to char datastring[82]; ?
[17:21] <PC1PCL> depends on how much data you need to store in it; if it's critical just add a bit more so you won't overrun regardless..
[17:22] <maxmed_> so there is no disadvantage to say making it datastring[100]
[17:23] astrobiologist (~astrobiol@213.205.241.235) left irc: Read error: Connection reset by peer
[17:23] <PC1PCL> you'd lose 20 bytes of memory somewhere, but that is probably not a concern
[17:24] <Lunar_Lander> (I once had datastring[500])
[17:24] <Lunar_Lander> :P
[17:24] <daveake> I remember that well :/
[17:25] <maxmed_> ok, I'll change that. But that won't solve the mysterious change of callsign from MAX to GPS?
[17:25] <daveake> [500] means "I haven't a clue how much I need". [512] means "I'm a programmer and I still have no clue how much I need"
[17:26] <PC1PCL> probably not, for that I'd suggest putting some debug output in so you can see what is happening and if what you're expecting to be printed to the buffer is really printed there at every step
[17:26] <zyp> what does [0x200] mean then? :)
[17:26] <bertrik> [0x200] means you're an embedded programmer :)
[17:26] <zyp> heh

[17:28] <PC1PCL> looks like the program is uses mySerial.println() to dump informational stuff out; you could use that to print the datastring buffer after every snprintf to see what it looks like.

[19:38] <Reb-SM0ULC> hello
[19:39] <SP9UOB-Tom> evening All
[19:42] <LeoBodnar> lol thanks Tom
[19:42] <LeoBodnar> evening
[19:42] <adamgreig> hey LeoBodnar, do you use i2c to connect to the ublox, rather than serial?
[19:42] <LeoBodnar> yes
[19:42] <LeoBodnar> i2c
[19:43] <adamgreig> works fine I guess? any reason for that over serial?
[19:43] <adamgreig> if I can swap from serial to i2c then I get to use this serial port for something else useful so am considering it atm
[19:43] <LeoBodnar> just thinking why i did this...
[19:44] <amell> weight?
[19:44] <amell> :)
[19:44] <adamgreig> clocked interfaces are nice and i like spi, but i2c has that annoying ability to stall if its state machine gets sad
[19:44] <LeoBodnar> mostly because serial lacks packet synchronisation
[19:44] ak4rp (~hp@254C2F7A.nat.pool.telekom.hu) joined #highaltitude.
[19:44] <adamgreig> aah, that's nice. hadn't considered that but yes, makes life neater
[19:44] <LeoBodnar> if (stall) reboot;
[19:44] <adamgreig> well indeed
[19:45] <adamgreig> certainly a manageable event :P
[19:45] <adamgreig> cool, I will make the swap I think, thanks
[19:45] <LeoBodnar> i have a timeout in all i2c blocking routines and if they lock up i reboot
[19:45] <LeoBodnar> i think it only happened on a few dodgy MAX-7 modules
[19:45] <adamgreig> this is gonna be running an RTOS so the i2c stuff will be in its own thread anyway, plus a watchdog for good measure I think
[19:46] <LeoBodnar> yeah
[19:46] <LeoBodnar> so reboot will cleanly intialises i2c hardware and start again
[19:46] <adamgreig> can you reboot the max7 though? or just reboot the pic?
[19:46] <LeoBodnar> (sp)
[19:46] <adamgreig> I note it has a RESET line that perhaps I should hook to an IO
[19:47] <LeoBodnar> i reboot the pic and also give hardware watchdog reset command to MAX
[19:47] <LeoBodnar> in reverse order that is
[19:47] <adamgreig> how do you send the reset command to the MAX if i2c has stalled?
[19:47] <LeoBodnar> if you can assign RESET line it's better
[19:47] <LeoBodnar> i have run out of spare pins a long time ago
[19:47] <adamgreig> heh
[19:48] <adamgreig> still got a few spare. amazing how quickly they get used up though
[19:48] <LeoBodnar> just note pulling reset does not make MAX consume less current
[19:48] <LeoBodnar> the opposite even

[19:48] <adamgreig> luckily not too worried about power for this, only need a few hours runtime per pack
[19:48] <adamgreig> and the gps usage will be the least of my worries compared to near continuous irdium
[19:48] <LeoBodnar> then use RESET of course
[19:48] <SP9UOB-Tom> you can also kil the power to the gps module

[19:49] <adamgreig> now for the next decision, whether to keep the LNA+SAW or just connect the antenna right to the ublox
[19:49] <LeoBodnar> but power up usually creates a dip on system power bus

[19:50] <adamgreig> haha yes perfect
[19:50] <SP9UOB-Tom> Yeah !
[19:50] <adamgreig> just jettison the ublox if it hangs

[20:34] <maxmed> Can you use 2 AA batteries as an unregulated power supply for Ublox max 7 GPS?
[20:35] <SP9UOB-Tom> maxmed: sure
[20:35] <SP9UOB-Tom> just add few blocking capacitors
[20:36] <maxmed> Is that just a capacitor put across the battery terminals or one in series with the battery?
[20:37] <Upu> 7C Maxell
[20:37] <SP9UOB-Tom> maxmed: in parralel to module supply pins, as close as possible
[20:37] <Upu> but I would recommend you use a regulator
[20:38] <maxmed> So I just put a capacitor going from the ground to VCC on the on the GPS module. What size capacitor would you recomend?
[20:39] <SP9UOB-Tom> 100n and 100p in parallel
[20:39] <SP9UOB-Tom> but these values are not critical
[20:41] <mikestir> maxmed: did you get the software sorted?
[20:43] <maxmed> mikestir - hard to say, I still haven't managed to change the call sign, I may have fixed the new line issue but can't get a gps lock so can't see if it works.
[20:43] <mikestir> have you got it near a window (or preferably outside)?
[20:44] Nick change: BitEvil -> SpeedEvil
[20:45] <maxmed> Yes been putting it outside, it's odd today it has generally been really fast getting a lock in a few minutes but left it outside for half an hour in the same spot as before and it didn't get a lock. It could be because I added the SD card writer which is using up the available current
[20:46] <mikestir> the gps constellation changes throughout the day, so it can take longer to lock at certain times of day than at others
[20:46] <mikestir> that's especially true if you have an obscured view of the horizon, like trees, buildings, etc

[20:49] <mikestir> the arduino pro mini schematic doesn't show the regulator they used (amateurs) so you'll just have to guess how much current is available and assume not enough
[20:50] <maxmed_> Yeh i cou
[20:51] <maxmed_> ...ldn't find the current of the supply anywhere. Thats why i thought about using a pair of AA batteries as a separate supply for the gps
[20:51] <mikestir> spark fun says 150mA
[20:51] <mikestir> I would have thought that would be ok, but SD cards can draw a bit of current when writing
[20:52] <mikestir> get it working without the sd card first
[20:52] <maxmed_> is 150mah enough for gps, radiometrix and sd card writer?
[20:52] <NigeyS> err..
[20:54] <maxmed_> ok, I'll remove the sd card writer from the circuit and give it a try tommorow. Hasn't helped that its been raining here all day so been hard to get to a very open area for testing.

[22:05] <Geoff-G8DHE-m> Leo, Is there any more log file to be returned covering the Russian bit?
[22:06] <LeoBodnar> unfortunately it's being replaced now but perhaps we'll get a few missing points tomorrow
[22:07] <arko> arent there parts you wont get back?
[22:07] <LeoBodnar> but not for the section from Novosibirsk to first loopy point
[22:07] <LeoBodnar> it won't change significantly, no
[22:07] <amell> will you be now extending your log buffer to 10 days?
[22:08] <amell> this calls for B-67 you know.
[22:08] <Geoff-G8DHE-m> OK guessed that was the position! I have it all as kml so far will play later ...

[22:12] Htbrdd (~Htbrdd1@irc.privateirc.com) joined #highaltitude.
[22:12] <amell> interesting that AIS can be received by satellites. What about transmitting AIS from a HAB?
[22:13] <amell> http://www.bbc.co.uk/news/science-environment-28372461
[22:14] <amell> oh. AIS position report is defined as 12.5W of power.
[22:14] <astrobiologist> *https://pbs.twimg.com/media/BtGaTiJIYAEkkAd.jpg:large
[22:14] <mfa298> AIS is marine band and I think you'de struggle to get a marine license for a device that's flying in the air

[22:17] <astrobiologist> chickened out of connecting it up until now
[22:17] <astrobiologist> then I found some old connector blocks and some resistors and went wild... too damn hot to sleep
[22:17] <amell> did it work?
[22:18] <astrobiologist> It is transmitting packet bursts from PocketPacket and the handheld is transmitting them using vox, yes
[22:19] <astrobiologist> and I recorded audio from the handheld onto the iPad, suggesting it is working in that direction too
[22:19] <astrobiologist> but so few aprs stations in London... and fewer still doing it "properly" on 144.8Mhz...
[22:20] <astrobiologist> everybody just using their Internet connection so more like find-a-friend for iOS or Google latitude really...
[22:20] <astrobiologist> will leave it running for a bit just in case someone picks up one of my packets...
[22:21] <astrobiologist> and maybe set it up with fl-digi the next time there is a balloon near London
[22:22] <Lunar_Lander> sounds good
[22:22] <astrobiologist> I think Mattbrejza did the circuit diagram but if it was someone else then sorry for misattributing :-)
[22:24] <Lunar_Lander> astrobiologist, how is your experiment coming along?
[22:25] <amell> i have listened for ages, on 144.8 here. and cant hear anything.
[22:26] <amell> in contrast, the soton websdr appears to have plenty of 144.8 activity
[22:26] <Laurenceb> LeoBodnar: sweeet
[22:26] <Laurenceb> thats epic
[22:28] <astrobiologist> where are you based amell?
[22:28] <Laurenceb> approaching 2 weeks
[22:28] <amell> elsworth
[22:29] <amell> b-63 puts sp3osj firmly into its place.
[22:29] <astrobiologist> Lunar_Lander: In the latest RSGB magazine there was a v interesting article about highly amplified OPTICAL circuits
[22:29] <astrobiologist> or "468 terahertz band DXing" as they put it ;-)
[22:30] <amell> Geoff-G8DHE-m: have you found a way to convert snus KML into a path ?
[22:30] <astrobiologist> can detect optical 1W signals scattered off dust in atmosphere over hundreds of miles in ideal conditions :-)
[22:30] <Lunar_Lander> cool
[22:30] <astrobiologist> surely a detector that sensitive should make a good spectrophotometer...
[22:30] <Lunar_Lander> yea
[22:31] <astrobiologist> so I could reuse for my experiment :-) fairly simple two, just 4 transistors
[22:31] <astrobiologist> then "all" I need to do is find a way of sterilising the balloon in flight
[22:31] <Lunar_Lander> yes
[22:31] <Lunar_Lander> can it like know what it sees so to speak?
[22:32] <astrobiologist> I have some ideas (like in-flight spraying) which even if they won't work will be cool flights
[22:32] <Lunar_Lander> yea
[22:32] <astrobiologist> (for instance the spraying would be like suddenly dumping ballast at altitude)
[22:33] <astrobiologist> so still some way off reflying but feeling more optimistic
[22:33] <Lunar_Lander> that is true
[22:33] <astrobiologist> and working towards my full UK radio license for the day we can do aprs over here airborne!
[22:33] <Lunar_Lander> sounds good
[22:33] <Lunar_Lander> hope your experiment will work
[22:34] <Lunar_Lander> I recall that you have been working on it a long time

[22:37] <astrobiologist> Lumar_Lander: fits and starts, it was when the UKHAS conference offered the radio exams that it really kickstarted things again. I'm really grateful to upu... craag... jcoxon... and anybody else who helped set that up
[22:37] <Lunar_Lander> yea
[22:37] <astrobiologist> amell: yes I considered that - cycloolefins like zeonor" are UVC transparent
[22:38] <Lunar_Lander> I recall that your experiment was something else back them
[22:38] <Lunar_Lander> wasn't it that you flew that experiment on a rocket once but it was destroyed?
[22:38] HixServer (~Hix@97e0125e.skybroadband.com) joined #highaltitude.
[22:38] <astrobiologist> I even bought a UVC LED but it was very fragile and expensive
[22:38] <astrobiologist> so I wouldn't be able to irradiate the balloon much... might try a mercury lamp instead but quite bulky
[22:39] <amell> dont think UV laser diodes are that expensive?
[22:39] <astrobiologist> and solar uvc would probably do the trick! but solar uvc unfiltered is extremely genotoxic so why is anybody seeing any stratobugs then?....
[22:39] <Lunar_Lander> don't know if lasers airborne are OK
[22:39] <astrobiologist> amell need UVC, say 260nm, so quite exotic photonics
[22:40] <amell> https://www.youtube.com/watch?v=qB0F1yR0LIY - i need to buy me a blu-ray :)
[22:40] <astrobiologist> Lunar_Lander it is basically the same experiment... I got greedy and went for both a balloon flight and a rocket flight with the same prototype... luck ran out!
[22:40] <Lunar_Lander> yea
[22:41] <Lunar_Lander> if I recall correctly there were those liquids and when the correct bacteria were there they could be counted
[22:41] <astrobiologist> detector on prototype was a DVD pick-p with preamp, and then an opamp circuit
[22:41] <astrobiologist> but it didn't work!
[22:42] <amell> doesnt the bacteria fluoresce in UV? hence easier to count?
[22:42] <astrobiologist> Lunar_Lander: 1) sample air for bugs. 2) Lyse open bugs. 3) amplify DNA from bugs. 4) add dye that detects amplified DNA. 5) check it in fluorometer
[22:43] <amell> sounds a lot to fly !
[22:43] <Lunar_Lander> yea
[22:43] <Lunar_Lander> complex
[22:43] <Lunar_Lander> like the Viking biolab
[22:43] <astrobiologist> can only detect fairly terrestial bugs with known DNA to amplify

[22:44] <astrobiologist> but seemed a reasonable way to stary
[22:44] <amell> a guy i know was working on a submersible robot, which would autonomously look for life on Europa underwater.
[22:44] <Lunar_Lander> but with amplify you don't mean PCR?
[22:45] <astrobiologist> amell: we did think of adapting it to look for signs of cellular stress etc from the deep horizon spill, that was going on at the same time :-)
[22:46] <astrobiologist> Lunar_Lander isothermal amplification, not PCR. the latest thing!
[22:47] <Lunar_Lander> cool
[22:47] <astrobiologist> http://www.twistdx.co.uk/
[22:47] <jarod> Maxell bertrik ^
[22:48] <Lunar_Lander> cool
[22:49] <Lunar_Lander> hope it works out
[22:49] <Lunar_Lander> the other concepts used traps which were baked out until a certain altitude or so
[22:50] <Lunar_Lander> and then just took in air and there was a filter or so
[22:51] <astrobiologist> microbiologically, I just don't believe the types of bugs being dound
[22:51] <Lunar_Lander> ah
[22:51] <astrobiologist> therefore I think they must be contamination from the trap, balloon, or in the lab
[22:51] <Lunar_Lander> yea I was very interested in your project from the start I must say
[22:51] <Lunar_Lander> yea
[22:52] <astrobiologist> so: need to sample in flight (so no lab contam), and sterilise balloon
[22:52] <Lunar_Lander> yeah

[22:54] <Lunar_Lander> :(

[23:01] <astrobiologist> it's just audio though Lunar_lander
[23:02] <Lunar_Lander> ah
[23:02] <Lunar_Lander> that could work
[23:04] <astrobiologist> if I get something rigged by this year's conference then I'll bring it along and maybe someone else could listen in on 144.8 and see if they can decode the packets?
