[10:48] <hyde00001> Houston we have a problem...
[10:50] <jonny_eal> if it did reboot then it may just need to get a GPS lock again?
[10:51] <nmcc> Thats a reboot - the counter on 3 is a giveaway
[10:54] <daveake> It is a reboot. And not just the Pi (this is a PITS ?) - the GPS has lost power also otherwise it would have a position
[10:54] <nmcc> And yes, it will then take a short while to get a lock. Sadly I cant hear it so far up North as my directable Yagi is blocked by a hill.
[10:55] <daveake> If it was just the processor rebooting then it'd have a GPS position by the 2nd sentence

[11:27] <Darkside> ah, raspberry pi + limesdr
[11:27] <Darkside> i hope they have some heatsinking
[11:27] <Darkside> and an external radiator
[11:28] <Darkside> the problem isnt going to be when its in flight (probably..) the problem is when it lands and sits on the ground for an hour before recovery..
[11:28] <fsphil> wish we could do that here
[11:32] <Phil_M0DNY> http://predict.habhub.org/#!/uuid=6a1dcfb14967eb100e089b03db67c6a1c37e1888
[11:32] <Phil_M0DNY> very little wind
[11:33] <Ian_> I have a Raspberry Pi 3B+ sitting here and the ambient is popping it's little gates at the moment, with the temperature soaring as if I watch any YouTube. That's in a dark man cave aka the living room, not in direct sun, so I know what Darkside refers to as regards the heatsinking. My science is often sedate spectator stuff. :)
[11:33] <Ian_> UK not such a hot summer day.
[11:34] <fsphil> The Pi 4 gets toasty just sitting a terminal prompt
[11:34] <Kryczek> Ian_: anything using the CPU a lot in `top` ?
[11:37] <Ian_> I will have a squint, but not a lot - xorg, chromium-browser and lxterminal are the main suspects.
[11:38] <SpacenearUS> New vehicle on the map: 03OZ1SKY_chase - 12https://tracker.habhub.org/#!qm=All&q=OZ1SKY_chase
[11:40] <Ian_> I saw a YouTube heatsink bit re the RPi 4B yesterday and the fact that there has been a software patch to mitigate the USB circuitry heat output. It's only a matter of time before one gets immersed in light mineral oil - BigClive.com lava lamp HAB data project perhaps :)
[11:41] <Kryczek> :D
[11:41] <Kryczek> +1 for a bigclivedotcom project
[11:41] <Kryczek> and it needs to be pink
[11:41] <Ian_> He could throw in a few chips for a slow cook perhaps.
[11:41] <nmcc> Will need a big balloon to fly it
[11:42] <Ian_> I can't see the RPi 4B making it into airborne tracker/system use any time soon due to it's weight of course, but the heat issue would be a serious nut to crack.
[11:43] <Darkside> hell, even the new pi model A is bad
[11:43] <Darkside> i was going to fly one of those, then reconsidered after i had it running in a box for 20 minutes on the bench
[11:43] <Darkside> im glad i did, as it ended up being a 35 degree day when we launched it, and it was sitting on the ground for a good 30 min before recovery
[11:44] <Darkside> australia is very dry. I worry about my payloads catching fire
[11:44] <Ian_> I think that I have a model A, but it hasn't seen the light of day yet.
[11:44] <fsphil> don't think heat will damage them, they'll just throttle down the clock
[11:44] <Ian_> I worry about the land around your payloads catching fire Mark :)
[11:44] <Darkside> exactly
[11:44] <Darkside> i do not want to be responsible for starting a bushfire
[11:46] <Ian_> What with the Zeusbot and tracker audit trail withholding plausible deniability when plod says, gday, gday, what goes on here?

[11:47] <Ian_> It's not the prison food that I would necessarily worry about either . . .
[11:48] <Kryczek> doesn't Australian Police reply with "Good call!" if you bribe them with a can of Foster's?
[11:49] <Darkside> fosters?!
[11:49] <Darkside> f**k off.
[11:49] <Ian_> I often used to wonder about military radio equipment working in a Land Rover sitting in the sun in what used to be Aden, South Yemen, Yemen . . . serious burns from the metal dash from the ambient sunlight soaked metal, before the pixies start working their magic under the hood.
[11:49] <Ian_> XXX
[11:49] <Darkside> first off, fosters doesnt exist here
[11:49] <Darkside> its export only
[11:49] <Kryczek> Darkside: here in the UK it's marketed as Australian beer but I see on Wikipedia it says that it's not popular in Australia :D

[11:49] <Darkside> queensland*
[11:51] <fsphil> didn't know they had beer in queensland. wouldn't it just evaporate instantly?
[11:51] <Ian_> Yeah, I believe, then they sell it here in the UK as beer . . . we used to have so many sketchy beers back in the sixties and seventies, but these days your average drunk is a bit more discerning on his night out.
[11:51] <daveake> I think it only exists so that Australians can be triggered by its very mention
[11:51] <fsphil> lol
[11:52] <Ian_> Would any of you actually give house room to one of those party 7 creations these days?
[11:53] <Ian_> As long as it's ice cold and chugs like a train, then it has to be good :)
[11:53] <Darkside> daveake: lol
[11:53] <Darkside> daveake: i saw an ad for it in when in the UK 'Fosters: Australian for beer'
[11:53] <Kryczek> :D
[11:53] <daveake> See
[11:54] <Ian_> Yeah, and advertisers, marketing departments and politicians are known for telling the truth
[11:55] <daveake> It's like Oz having adverts saying "Carling: British for Beer"
[11:56] <Kryczek> there seems to be some kind of Jedi mind trick going on in the UK... As a Frenchman here I do not understand people revelling like "Mmmmm, French wine!" in what is clearly export-only neverheadofit bottom shelf grape juice concentrate mixed with ethanol
[11:56] <Ian_> The really good micro brewery beers don't get advertised, because they get drunk too fast for that to be useful. Word of mouth . . . burp :)
[11:59] <nmcc> Darkside: did you ever have a brand of clear sticky tape called Durex or is that a Jasper Carrot (comedian) myth?
[12:00] <Darkside> lol
[12:00] <Darkside> Durex is a brand of condom
[12:00] <nmcc> Yeah, but the joke was pretty funny at the time (early 80s)
[12:00] <nmcc> Aus tourist goes in to stationers and asks for a roll of Durex
[12:01] <Ian_> Kryczek it used to be really bad back in the late 50's, with rail tankers of wine being openly watered down with a hosepipe for the UK market . . . then there was the enterprising German who fortified his wine with glycol to give it sweetness and others all over Europe got caught using his wines to 'improve' their own by fortification. That would b
[12:01] <Ian_> e around 1976 - 1978 time. Great scandal.
[12:02] <Kryczek> Ian_: I didn't know about that, explains quite a bit :) Thanks!
[12:05] <Ian_> The Brits in the late 50's and early 60's were largely a fairly naive set when it came to drinking wine in the general populace and if an extra twenty gallons of water in the tanker wasn't likely to be noticed, then hey it's a great boost for the bottom line for the price of a hosepipe.
[12:05] <Ian_> The problem was that everyone wanted to add an extra 20 gallons.
[12:07] <daveake> And now they sell water for more than the cost of wine
[12:07] <daveake> probably

[12:10] <hyde00001> Thinking about EALMOON rather than booze for a moment (I know how dull..) its been a while since i've looked at PITS voltages so I can't remember if this is normal: in the ~40 mins of telemetry I got the internal voltage steadily drops from 4.7 to 4.0. I have two lines of tracker data at 4.0 then it dies. I received four more lines a few minutes later, the first two with zero volts the last two wit
[12:10] <hyde00001> h 3.7. Is this indicative of under voltage on the batteries (aka bus b...)
[12:12] <Ian_> https://www.thewinestalker.net/2015/04/austria.html I think that the trend began in the 1970's; and it was apparently Austrian and not German in origin. The vineyard in question was rumbled because of excess greed. They claimed the ethanol glycol on their tax return as a legitimate business expense and piqued the curiosity of a tax inspector who wo
[12:12] <Ian_> ndered why a wine producer would require that much anti-freeze [summer coolant with a dash of tonic :) ]
[12:13] <Ian_> The trend seems to have reoccurred every few years around the world ever since.
[12:15] <daveake> hyde00001: Normally the voltage should be pretty flat, though of course it drops with usage and with temperature
[12:15] <daveake> That's a lot of drop
[12:15] <Ian_> I wonder if EALMOON was using genuine fresh Ultimate Lithium batteries or something else?
[12:17] <daveake> The actual voltage might be different because (unfortunately ....) one batch of PITS had different divider values so I had to add a multiplier setting to pisky.txt, which nobody ever bothers to set
[12:17] <daveake> But the percentage drop you mentioned is large
[12:18] <daveake> Bus B undervolt indeed
[12:18] <daveake> Except it's bus A and there is no bus B ....
[12:19] <hyde00001> except there are no really good bus A Apollo references that I'm aware of...
[12:20] <daveake> :)
[12:20] <hyde00001> Sounds a good analysis - voltage drop seemed large to me...
[12:21] <daveake> The lithium AAs start at 1.8V but drop to 1.7 almost immediately. It's pretty flat from (IIRC) 1.5 to 1.2 then drops like a stone
[12:22] <daveake> http://data.energizer.com/pdfs/l91.pdf
[12:25] <daveake> So if you look at the "digital audio" application test on 2nd page to the right, that's fairly close to PITS usage profile, 1.5V --> 1.2V takes most of the life of the battery.
[12:25] <hyde00001> so just wondering out loud if they had x3 AAAs rather than x4 AAs (as I an many others fly) and then didn't change batteries from their aborted launch last week...
[12:25] <daveake> Well, it does look like the end of the curve to me
[12:26] <daveake> It's hard to give a run time as it depends on so much e.g. which Pi, but a set of 4 AAs should be enough for 3-4 flights
[12:26] <daveake> That said, I always open a fresh packet
[12:27] <Darkside> jeez i wouldn't dare re-use batteries
[12:27] <daveake> And yes I do have a stockpile of used cells for fitting to anything that isn't a tracker :)
[12:27] <nmcc> I make a ritual out of opening the sealed packet of in-date Energizers at the launch - think Holy Hand Grenade of Antioch - and if its with students, checking the voltage because once, one of them put a battery in the wrong way round so we only had two x V at first.
[12:27] <daveake> yup
[12:27] <Darkside> daveake: same with the massive pile of used cells
[12:27] <daveake> I do check the voltage to
[12:27] <Darkside> good for remote controls :P
[12:27] <daveake> 1.8V+ or it ain't flying
[12:28] <nmcc> Me too, this summer Im making a Lego Battery Tester to sort through the box of around 300 - I do robots a lot as well.
[12:28] <daveake> Yeah, and meece, and putting in trackers for testing
[12:28] <jonny_eal32> We used 4 x AAs
[12:28] <hyde00001> From a RTTY/LoRA PiA+ PITS flight that got stuck up a tree I got almost exactly 21 hours of pictures and telemetry
[12:29] <daveake> Yup
[12:29] <jonny_eal32> That was using a USB battery pack
[12:29] <jonny_eal32> this flight we used alkaline AAs
[12:29] <daveake> There you go then
[12:29] <PE2BZ> ALKALINE ?
[12:29] <daveake> Alkalines are shite for HAB
[12:30] <daveake> Heavy and awful for high current demand
[12:30] <Darkside> and they freeze
[12:30] <daveake> Not with a Pi, probably :D
[12:30] <Darkside> true
[12:30] <daveake> But yes, they don't like the cold
[12:30] <jonny_eal32> We had a hand warmer on them
[12:31] <daveake> They don't work either
[12:31] <daveake> Just use Energizer Lithiums
[12:31] <jonny_eal32> We ran out
[12:31] <Darkside> buy more?
[12:32] <daveake> See https://ukhas.org.uk/guides:how_to_lose_your_flight
[12:33] <nmcc> BakTrak ran for 36 hours on 5 x AA, AVR, LoRa, GPS and sending me a text message every 10 minutes once it had landed - the powers there.
[12:33] <hyde00001> Shame - unlucky. Unhelpful comment now, but If you need stuff last minute on another occasion give me a shout I'm in east Oxford so not far away...
[12:33] <nmcc> Always have spares. Why buy one packet when you can buy three. Yes, three x £9 is £27, but thats less than one lost PITS

[12:34] <daveake> The nominal capacity of Duracells isn't an issue; it's that if it's cold and/or the drain is high, the capacity drops like a stone
[12:35] <jonny_eal32> we are still hoping for a reboot when it starts descending
[12:35] <nmcc> Sorry if we are being harsh, but Ive (mostly) learnt - Im a regular customer on the Uputronics website due to making and allowing other to make stupid decisions about launches.
[12:36] <nmcc> Somone got a string from Apollo - you may be in luck
[12:36] <daveake> It will get warmer and you might get lucky
[12:36] <PE2BZ> I guess that´s a complete different Apollo ?
[12:36] <nmcc> Dang
[12:37] <nmcc> Id go to the predicted (by the predictor, not by the tracker) landing site and see if you can hear anything
[12:37] <daveake> One of my Pi floaters rebooted when it tried to cutdown, then tried again, and again, till eventually it got past the longitude window for the cutdown, then it was happy :)
[12:37] <daveake> Yeah do that
[12:37] <daveake> The MTX2 might be whistling even if the Pi isn't running
[12:38] <daveake> I say might, as the transmitter enable line might not be high enough
[12:38] <jonny_eal32> APOLLO is in Devon
[12:39] <jonny_eal32> Is that a different APOLLO
[12:39] <nmcc> Wouldnt the prediction indicate that it should have landed by now - if so, line of sight will be poor but if you are within a couple of kms you should be OK
[12:39] <nmcc> Must be, just not flight approved.
[12:40] <daveake> Yeah, drive round the area with a radio tuned to the RTTY frequency. Though if the MTX2 hasn't been set to the frequency by the Pi it'll still be on default whatever that is
[12:40] <hyde00001> Earlier today, someone was testing a different payload name at the same location in Devon only it was parsing as they didn't have a payload document. I guess they just changed their tracker name...
[12:40] <daveake> Upu: What's the default frequency for PITS MTX2 ?
[12:41] <hyde00001> wasn't parsing...
[12:41] <daveake> Shame there's no payload ID ownership
[12:41] <daveake> Though that one was always going to get reused
[12:42] <nmcc> At a later date I have suggestions for various additions to the telemetry string to help or a non-parsed string transmitted occasionally - like PITS version, OS, owner etc
[12:45] <hyde00001> more efficient to lock it on the habitat side I think as that keeps the sentence shorter which means more decodes
[12:47] <nmcc> Something should be emitted from the payload so we know what reality is - like the RISH flight where the LoRa freq wasnt known until someone found it. Doesnt have to be often and lora_gateway doesnt have to pass it on to habitat
[12:47] <hyde00001> In other news, looks like the database/map can keep up now after all the recent database maintenance. Thank you to all the people who maintain..
[12:48] <hyde00001> Calling mode...
[12:49] <Darkside> i think compact is still running
[12:50] <Darkside> nope we are definitely lagging at the moment

[12:50] <nmcc> Or Tx its setup on an agreed, known, universal frequency at random intervals inside 10 minutes
[12:50] <Darkside> my about 5 minutes
[12:50] <daveake> nmcc If it's part of the sentence then it has to go to habhub, because it's habhub that does the parsing
[12:51] <Darkside> huh, 10 seconds to parse a sentence. thats the longest i've ever seen it
[12:51] <daveake> wow
[12:51] <nmcc> Id not have it as part of the sentence otherwise it would increase the size and increase errors.
[12:51] <nmcc> Id just have it send somethign we can read in the logs or on lora_gateway console or similar
[12:52] <daveake> A "meta-data" message periodically sounds plausible
[12:53] <fsphil> possibly the one good feature aprs has
[12:54] <hyde00001> Oooh re parsing. Yeah called that wrong.. I was just thinking about the EAL flight which seemed to go ok... More active uploads in the logtail now than earlier in the day
[12:55] <hyde00001> logtail moving much quicker - i guess now quick enough...
[12:55] <hyde00001> as an aside, how much I am part of the problem by looking at the logtail to see if there is a problem??
[12:56] <Darkside> nah
[12:56] <PE2BZ> Depends on the speed of your braillescreen ;-)
[12:56] <hyde00001> meant to type "- i guess NOT quick enough"
[12:56] <jonny_eal32> Very sad to lose APOLLO but thanks for tracking.
[12:57] <nmcc> Hey, its not over until youve been to the landing zone - travel hopeful
[12:57] <hyde00001> jonny_eal32 - you in the Sandy area having a listen??
[13:06] <jonny_eal32> We are hoping the batteries warm back up and it turns back on
[13:08] <jonny_eal32> Predicted landing location is around northampton
[13:08] <jonny_eal32> but since it's not transmitting we don't think we'll pick anything up even if we go nearby
[13:09] <daveake> Not even a carrier ?
[13:13] <jonny_eal32> wouldn't a carrier be picked up while it was still in the air?
[13:13] <Darkside> yes, but not for long if its on its way down...
[13:15] <SpacenearUS> New position from 03N6CVO-11 after 0312 hours silence - 12https://tracker.habhub.org/#!qm=All&q=N6CVO-11
[13:17] <dg2fs> Maybe you get lucky and someone finds it. Someone found our balloon payload in the dessert in south africa two years after the flight.
[13:17] <dg2fs> A bit of waterproof paper with an e-mail can be a pretty good backup-backup-tracker.
[13:18] <jonny_eal32> we do have a message on it, so we are hoping to get a phone call at some point
[13:20] <fsphil> there's hope, as long as it doesn't land in the yorkshire dales
[13:21] <SM0ULC-David> jonny_eal32: any backuptracdker?
[13:21] <daveake> I'd give it a go. I managed to find a lost but whistling payload that landed 150m from the prediction (last position we had was during ascent with 10km to go)
[13:22] <daveake> All I had to go on was that last known position, burst time and approx landing time, to which I fitted a prediction

[13:39] <jonny_eal32> does anyone know who CAEN_MC1 is because they are the only one who tracked APOLLO in Devon
[13:41] <jonny_eal32> We think it could have been hit by a plane and taken to the airport right next to the last tracked location, it then was taken home and unwrapped, in the process turning the tracker back on and was the tracked by CAEN
[13:44] <Darkside> if it was hit by a plane i suspect it wouldnt not still be transmitting

[13:53] <dg2fs> Lost payload always make me thing of "alternative" tracking/recovers
[13:53] <dg2fs> -
[13:54] <fsphil> tracer smoke
[13:54] <dg2fs> .. recovery techniques:
[13:54] <dg2fs> 1) Put on something really radioactive and watch some goverment agency do the work for you
[13:54] <dg2fs> 2) Use pheromones of whatever animal is most common in the area. Then head for the largest herd
[13:54] <fsphil> shouldn't cause too much of a panic
[13:54] <nmcc> So, just use a Pi 4 in a polystyrene box
[13:54] <SIbot> In real units: 4 in = 10.16 cm
[13:54] <daveake> Set fire to surroundings when landing
[13:56] <nmcc> Attach a Guide Dog Puppy and it can walk home
[13:56] <fsphil> call it Laika
[13:56] <fsphil> poor Laika :(
[13:57] <dg2fs> really long thin string
[13:57] <daveake> Launch a homing pigeon
[13:58] <Kryczek> dg2fs: 1a) make it do smoke signals like Indians used to, but with mushroom clouds
[13:58] <fsphil> really though, I'd just fly two radio trackers if it's an important payload
[13:58] <fsphil> * of different types
[13:59] <nmcc> Martian landing style inflatable cushions - so its huge
[13:59] <nmcc> fsphil: worked for me - just need to get it down from the tree now
[13:59] <fsphil> that's a different problem
[13:59] <fsphil> solved by chainsaws
[14:00] <Kryczek> avoid trees: use a bottle as a case, and make sure to drop in the ocean
[14:00] <daveake> Unless it's weight-limited, I always fly a second (and as you say, different type of) tracker
[14:00] <fsphil> Kryczek: that's on my todo list
[14:01] <fsphil> though it's been on my todo list for a few years now
[14:01] <Kryczek> :D
[14:01] <fsphil> stupid short earth day
[14:01] <nmcc> BakTrak is in a SodaStream bottle and should, in theory, float if it finds water
[14:01] <daveake> I still have my payload for a sea landing, with separate SSDV repeater, sat waiting to fly
[14:02] <daveake> It did fly once, but Pawan made it come back down
[14:02] <nmcc> Look at the tides, sleep often and it could be a beach retrieve
[14:02] <daveake> btdt :D
[14:02] <nmcc> Perhaps I should make BakTrak fire proof and then I can burn the tree down &
[14:03] <dbrooke> hmm, ssdv providing more up to date tracking than the map
[14:03] <Kryczek> fsphil: leapfrog fishpi.org, make yours both HAB *and* autonomous ship!
[14:03] <daveake> heh, add telemetry to the overlay :)
[14:03] <daveake> PITS has that built in just insert with imagemagick
[14:04] <nmcc> My first school flight - RAF bombing range at Skegness, washed up and retrieved by small dog the next day
[14:04] <dbrooke> tlm overlay would be good with this downward view
[14:04] <daveake> Now that's a piece of HAB kit that I don't have ....
[14:04] <Kryczek> nmcc: make it attract lightning then it can use the tree as a beacon! :D
[14:05] <fsphil> release an ionised gas on the way down?
[14:05] <daveake> I did once overlay with a country flag
[14:05] <daveake> That was a floater and his had a vector map of Europe to choose the right flag
[14:06] <daveake> That was the one that sent SSDV images of Thunderbird 5 etc at night
[14:07] <nmcc> What is it that we see under XPI?

[14:58] <nmcc> Tie a boy band member to the payload and allow the fanbase to find it/them
[14:58] <daveake> IIRC SITS tried that with a watch on a commercial flight
[14:58] <daveake> AFAIK not found
[14:59] <nmcc> In those days they were using SMS
[14:59] <hyde00001> So why is the parsing/map sooooooo much worse this afternoon than this morning?? 4 payloads being uploaded rather than 2 this morning??
[14:59] <hyde00001> Is that system that sensitive to load??
[15:00] <daveake> It's the parse that's slow, so more sentences to parse = more lag over time
[15:01] <hyde00001> so several of us should stop uploading as others have the Elsworth flight covered...???
[15:01] <fsphil> it shouldn't be slow. wonder what it's doing to make it so
[15:01] <nmcc> I hear there is still a compact running
[15:01] <fsphil> if it's doing a db lookup each time, maybe that could be cached?
[15:01] <daveake> Indeed
[15:02] <daveake> A list of recent payload docs
[15:02] <fsphil> wasn't it was slow before the compacting started?
[15:02] <daveake> Dunno if it's doing a lookup per upload or per unique sentence
[15:02] <nmcc> Yes, because it needed compacting
[15:02] <hyde00001> We have invented HAB time travel.... We can see where payloads were half an hour ago...

[15:36] <nmcc> Very small packets, so it will be the ability of the server to accept connections - unless you have very wet broadband string / satallite or dialup connection.
[15:39] <hyde00001> Never seen such a queue before (up and down but frequently in the teens). Consistent with today lag on the server then...

[15:45] <nmcc> Apart from software moving on that may be updated or optimised, I gather there is newer more powerful kit that it could be migrated to thats going spare.
[15:46] <daveake> Basically, use the pits predictor which my Android app shows on my non-SNUS google map
[15:47] <daveake> The app doesn't currently feed *from* hab.link but I may well add that
[15:47] <daveake> It does have a feed from habhub, but not altogether useful at the mo
