[00:00] <aadamson> I based it on some other flights from LeoBodnar and Upu at similar weights
[00:00] <arko> cool
[00:00] <aadamson> but those little (huge water collectors) solar panels aren't helping the moisture issue
[00:01] <aadamson> it needs to be about 5-7 grams lighter and then it might have a chance to be above the fray
[00:01] <aadamson> but there is some really bad (tornados etc) storms that way this afternoon/evening
[00:02] <aadamson> plus it's cooling down due to the sun going down.
[00:02] <aadamson> ah, in fact it's below zero or at it
[00:02] <aadamson> the temp keeps hovering around 0 (a software bug I realized after the fact)
[00:03] <Laurenceb_> interesting altitude keeps levelling off
[00:03] <Laurenceb_> you need a Leo style custom envelope and ~10gram payload
[00:03] <Laurenceb_> then you can fly at 12km
[00:04] <Laurenceb_> interestingly B-54 is about a Km lower than normal
[00:04] <DL7AD> its the humidity
[00:05] <SpeedEvil> The solar panels are pretty irrelevant compared to the massive balloon
[00:05] <aadamson> Laurenceb_, yeah mostly I need need about -7 less grams :)
[00:05] <DL7AD> Laurenceb_: HYSPLIT predicted up to 50% humidity
[00:05] <arko> aadamson: what was your mass?
[00:05] <aadamson> SpeedEvil, that is true... btw, has anyone tried any of the window fluids that repel water
[00:06] <aadamson> arko, 23grams was payload
[00:06] <SpeedEvil> Interesting point
[00:06] <arko> oh wow, pretty heavy
[00:06] <aadamson> I don't know if they would attack the material is all
[00:06] <Laurenceb_> interesting idea
[00:06] <aadamson> arko, yeah about 5 of that was my first build
[00:06] <aadamson> I could drop 5 easily
[00:06] <Laurenceb_> do they just cause the water to form a thin film?
[00:06] <aadamson> for next take
[00:06] <aadamson> I saw a really interesting one today... let me find the link
[00:07] <aadamson> http://www.hydrobead.com/
[00:07] <aadamson> or rainx or something like that
[00:07] <DL7AD> Laurenceb_: theres coming rain from the south: http://puu.sh/9bamp/9deb90c2c0.png
[00:07] <aadamson> course I don't know what they might weigh
[00:07] <aadamson> also probably just some wax would do the same thing
[00:08] <SpeedEvil> aadamson: Well - product volume divided by thickness
[00:08] <Laurenceb_> im not sure how they work
[00:08] <Laurenceb_> and if it will help
[00:08] <SpeedEvil> Patents!
[00:08] <aadamson> problem probably is the *nooks and crannies* that hold the droplets
[00:08] <SpeedEvil> Presumably
[00:08] <Laurenceb_> if it causes the water to form a thin film it might help
[00:08] <Laurenceb_> i dunno if they actually stop the water
[00:08] <Laurenceb_> or just stop the mist
[00:09] <Laurenceb_> http://en.wikipedia.org/wiki/Anti-fog
[00:09] <aadamson> I might sacrifice a balloon to rainx and see... here is the msds for it - http://www.co.vermilion.il.us/MSDS/EMA/88-Sopus%20Products_Rainex_Deicer.pdf
[00:09] <Laurenceb_> minimizing surface tension, resulting in a non-scattering film of water instead of single droplets
[00:09] <Laurenceb_> might not help then
[00:10] <aadamson> most cause the water to stay together instead of disperse and then *stream off*
[00:10] <aadamson> as you say... for a thin film
[00:10] <aadamson> form
[00:10] <SpeedEvil> Or if the surface film average thickness is smaller than the droplet
[00:11] <Laurenceb_> yes
[00:11] <Laurenceb_> but if you have condensation its going to get thickrr
[00:11] <aadamson> unfortunately w7qo-6 is being rained on rather hard right now I think
[00:12] <aadamson> this is even worse than last night it managed to stay on the fringe and either iced up or rained up (and down)

[00:27] <N2NXZ> I knew the email was familiar...lol.
[00:27] <arko> haha
[00:28] <N2NXZ> Just sent you a message,email

[00:28] <arko> who do we contact?
[00:28] <arko> i dont see an option to change the callsign in my settings
[00:29] <N2NXZ> Was that you who posted the launch info?Or did someone use your info?
[00:29] <arko> i did, but i gave my callsign N6ARA
[00:29] <arko> no clue how they got your call
[00:29] <N2NXZ> No big deal...not hurting anyone
[00:29] <N2NXZ> It was just mysterious...lol
[00:29] <arko> heh yah, i'll kick them an email anyway
[00:29] <arko> haha
[00:30] <N2NXZ> The guy who posts the schedules is pretty cool...he prbably still remembers my call when he messed my posting up last year
[00:30] <arko> haha
[00:30] <arko> yeah
[00:31] <N2NXZ> No harm no foul...as long as it was not someone using our information,had to check to be sure.
[00:31] <N2NXZ> I rememebr your screen name...so came here to check with you

[00:47] <aadamson> it's on 4 minute beacons now and missed the last 2... so it's out of digi range anyway it seems... I was hoping that it might get lucky and stay in coverage
[00:48] <aadamson> it's between indy and dayton, luckily it missed Interstate 70 (just south of it)

[00:58] <aadamson> got look for w7qo-6
[00:58] <aadamson> left atlanta yesterday, got rained on and went to the ground for 2 hours, took off again, went to 24k, then tonight it got rained on again
[00:58] <aadamson> only has 1.5 free lift so it doesn't take much moisture
[01:00] <N2NXZ> Watching it now...cool stuff

[01:04] <N2NXZ> Major storm system it looks
[01:04] <aadamson> lz1dev, yep... and that's what brought it down... last night it just stayed on the edge of the storm but today it got overtaken by this one.
[01:04] <aadamson> it does seem to be dissapating however which is good
[01:04] <aadamson> I checked no tornados and only slight lightning in the area
[01:04] <N2NXZ> If it heads this way...will get the RX going
[01:04] <aadamson> nothing severe
[01:05] <aadamson> for my whopping big 10mW :)
[01:05] <N2NXZ> lol..good enough\
[01:05] <aadamson> yeah, didn't know what to expect from battery/solar performance so planned qrp
[01:05] <aadamson> could have turned it up with no problem

[01:07] <N2NXZ> Now that looks cool as heck...:)
[01:08] <aadamson> ah LeoBodnar has been doing those for over a year so its nothing really
[01:09] <aadamson> N2NXZ, go have fun looking here - http://www.leobodnar.com/balloons/ - B54 is up currently on spacenear.us
[01:09] <N2NXZ> How is the data being copied...from what ground station?
[01:09] <aadamson> on mine, it's all aprs
[01:10] <N2NXZ> Oh...I was looking on this http://spacenear.us/tracker/
[01:10] <aadamson> on this flight... on LeoBodnar it's a combination of aprs and a SSB mode with active ground based hams/interested parties receiving and pushing the telemetry to a server
[01:10] <N2NXZ> Ok,let me organise my windows
[01:11] <aadamson> if B-54 says receiver:APRS, it's being pulled from aprs and sent to that server.... if it says other things, those are people who are actively listening and relaying via dl-fldig
[01:11] <aadamson> http://ukhas.org.uk/projects:dl-fldigi
[01:11] <aadamson> it's a very cool system they use in EU with this... they do that because some *most* countries don't allow airborne aprs
[01:12] <aadamson> so they use a free unlicensed ISM band in the 432mhz range
[01:12] <aadamson> or where LeoBodnar can do APRS from air he does
[01:12] <aadamson> also info here - http://ukhas.org.uk/guides:tracking_guide
[01:13] <N2NXZ> Already have dl-fldigi setup here.Used for last years trans atlantic attempt.
[01:14] <aadamson> ah, well there you go is what they use in EU for most things
[01:14] <N2NXZ> Someone piped in APRS for us. http://aprs.fi/info/a/HB-N2NXZ1
[01:15] <aadamson> yeah, they can do that, it's how you see w7qo-6 on spacenear
[01:15] <N2NXZ> Got it..

[04:58] <wotzup> There were two chat screens last time I looked - is there only one now?
[05:02] <wotzup> On a flight in Croatia recently I had a long nylon cord between the balloon and a number of payloads that needed to be separated due the experiments intertferening with each other. The cord got wet with a passing shower..
[05:03] <wotzup> All went well until the balloon burst abd the payload passed inot the stratosphere. The Spot 3 and the APRS units started to go further and further off track and the APRS altitude went wild too.
[05:06] <wotzup> After 15 minutes, both units normalised and "snapped" back on the true track. The cutdown unit also stopped communicating (RTTY) at that moment and went dead. The rest of the decent was okay - except it landded up a tree on a ridge with a mass of blackberries and rain
[05:07] <wotzup> I was thoinking some sort of static charge may have built up. I have never experienced such an anomily and on 2 separate tracking systems. Any thoughts.
[05:09] <wotzup> The units went off track in different directions. One to the Byonics MT-400 wandered to the west and the Spot3 indicated it was further south. Actually it started just before it exited the stratosphere
[05:11] <Darkside> probably no-one here atm wotzup

[08:09] <malgar> G8APZ: how much do you think the battieries will last?
[08:10] <malgar> there are a group of listeners in italy awaiting for you
[08:10] <malgar> *there is
[08:11] <G8APZ> G-04 reporting 2.8v at the moment, but telemetry on G-05 last night suggested it was around that level, so I would expect the battery on that to be getting critical soon!
[08:11] GW8RAK (~chatzilla@ joined #highaltitude.
[08:12] alain (5133bef0@gateway/web/freenode/ip. joined #highaltitude.
[08:12] <G8APZ> Low wind speed means slow progress towards Italy!
[08:13] <Upu> whats the batteries does anyone know ?
[08:13] mikestir-work (~mike@ joined #highaltitude.
[08:14] <G8APZ> Upu both now running from a single AA cell according to Graham's email
[08:14] <G8APZ> not sure how the battery volts stacks up with that statement!
[08:14] <G8APZ> unless he's using step up
[08:14] <G8APZ> buck
[08:15] <Upu> yup thats what was confusing me
[08:18] <G8APZ> given the start volts I'd have thought 3 cells, but that's a bit of extra weight for a pico
[08:19] <G8APZ> B-54 doing well.... crossed into N Africa and headed east
[08:20] <G8APZ> Morocco then Algeria
[08:20] LZ1NY (~LZ1NY@mail.daxy.com) joined #highaltitude.
[08:21] <G8APZ> B-54 heading somewhere between Sicily/Sardinia
[08:27] <G8APZ> Upu no updates for Grahams flights for a while. I wonder if that means no trackers or batt failure?
[08:27] gonzo_m2 (~gonzo@ joined #highaltitude.
[08:28] <Upu> not sure
[08:28] <Upu> possibly battery
[08:29] <G8APZ> Upu Leo's solar solution seems to be a great advance in battery life
[08:30] <fsphil> it'll be a while before the sun's output drops
[08:30] <Upu> well solar has always been the way forward
[08:30] <Upu> though I still think there is more life in primaries
[08:31] <Upu> I can get 75 hours from my tracker
[08:31] gonzo_m (~gonzo@ left irc: Ping timeout: 245 seconds
[08:31] <Upu> and I think there is still more to come with extreme power saving code
[08:31] <Upu> from a single AA
[08:31] <Upu> i.e turning the GPS off
[08:31] <Upu> I think 100 hours is theoretically possible
[08:32] <fsphil> or more, if you accept fewer updates
[08:32] <Upu> yep
[08:32] <Upu> but solar is the way forward for long duration
[08:33] <Upu> G-04 updated
[08:33] <G8APZ> Leo does save battery as well as solar charge by restricting the telemetry to every so many minutes
[08:34] <G8APZ> Oh good - map in UTC time.. was forgetting that
[08:35] <Upu> yup
[08:36] <G8APZ> Upu assuming just a simple beacon message with call, time, packet id, and blips in between, do you think GPS off for 30 mins at a time is enough?
[08:37] <Upu> I'd say 10 mins
[08:37] <Upu> I need to do some work on that
[08:37] <Upu> there are issues with shutting down the GPS
[08:37] <Upu> see the track from W7QO-6 as an example
[08:38] <G8APZ> OK - on Graham's current flights the location doesn't move much in 10 mins! On a windy day that may be totally different!
[08:38] <fsphil> you'd only want faster updates on ascent/descent
[08:38] <G8APZ> that's true, assuming recovery is planned
[08:39] <Upu> yeah I suggested to Leo he amend the code so if its descending increase updates
[08:39] simrun (~simrun@2a02:2658:1011:1::2:2178) left irc: Ping timeout: 245 seconds
[08:39] <Upu> always nice to know where it lands
[08:40] <fsphil> exactly
[08:40] <fsphil> there was an old idea of using a pressure sensor to detect changes in altitude
[08:40] simrun (~simrun@2a02:2658:1011:1::2:2178) joined #highaltitude.
[08:40] <fsphil> they're very low power devices
[08:41] <Upu> yeah I was going to do that and report the altitude via pressure with the GPS off
[08:42] <fsphil> pressure would be a useful measurement for foils anyway
[08:42] <Upu> right off to wash the car
[08:42] <G8APZ> Still lots of work possible on efficiency!
[08:43] <G8APZ> G-05 just updated!

[08:55] <malgar> G8APZ: he should be on.. but keep in mind that there are mountains 4000 m high to cross and the signal could be shadowed by them
[08:58] <G8APZ> malgar yes that's a factor with the zero degrees horizon blue ring
[08:58] <in3aqk> Hello G04 and G05 are note present on mi dl-fldigi why?
[08:59] <G8APZ> malgar - it depends on whether the mountains affect his view of the horizon.... it is surprising how soon they become insignificant

[09:01] <[1]Geoff-G8DHE-M> Ah I have the same problem :-( Some one has put in a document in unicode I wonder if it has affetected the D/B
[09:02] <in3aqk> Yes same unicode problema
[09:02] <in3aqk> problem
[09:03] <G8APZ> Both flights are 300baud 7n2, discontinuous Tx, Tx is on 434.125 and 434.510 (USB). The transmissions are time synchronised from the GPS clock to avoid Tx clashes.

[09:03] <[1]Geoff-G8DHE-M> It may also be that the Flight Document didn't specify more than a day

[09:05] <lz1dev> G-0x time windows has expired
[09:05] <G8APZ> You can find G-04 and G-05 in the ALL PAYLOADS tab
[09:06] <G8APZ> Configure/All payloads (testing)
[09:08] <in3aqk> yes, tried and found g05 but flight is not activable
[09:09] <G8APZ> Have to use Custom setting then
[09:09] <G8APZ> Op Mode / Rtty/ Custom 470 shift 300 baud 7 bits no parity 2 stop bits
[09:10] <in3aqk> ok thanks, now seems to works....
[09:10] <G8APZ> then save and close
[09:11] <G8APZ> oh, and in that same custom panel, change Receive filter bandwidth to about 300, and save
[09:11] <in3aqk> works, but not sure that will upload data as the flight is not really selected
[09:11] <in3aqk> so I'm only able to decode
[09:12] <G8APZ> don't use AFC and don't use Squelch on these flights... they both transmit on two frequencies and are about 1kHz apart

[13:56] <SpeedEvil> I guess 'descent >5m/s for 1000m' might work.

[19:22] <aadamson> anyone done any *landing detection*. Had a thought today that if on aprs, it might be good to move off the *main* frequency, or change the way you beep/boop/etc, when on the ground to make recovery easier. Maybe even *turn up the power* or change the interval.
[19:23] <aadamson> I have some thoughts, with either ascent or descent speed etc, but it needs to ground not flight level

[19:41] <JWP> Hi, i am getting al the pieces together for a first launch at the end of the summer, i wonder if there is any sample python code available for a uBLOX MAX-7Q module, NTX2 and raspberry camera?
[19:47] <mikestir> LeoBodnar: what do you do about rsid being sampled at 11.025 kHz? are you generating it by pulling the ref rather than using the 4060?
[19:51] marshall_law (~marshall_@97-93-250-127.dhcp.ftwo.tx.charter.com) joined #highaltitude.
[19:51] <aadamson> btw, Upu you can remove the import on W7QO-6, if it comes back to life, I'll pick it up on aprs.fi, but somehow I doubt that's going to happen
[19:52] <mfa298> JWP: you may be best off writing something yourself. Both because then you'll understand how it works (important when it stops working just before launch) but also things keep moving on so there are probably better things to do than the last person to launch a Pi with python code.
[19:52] <mfa298> e.g. there's now an excellent python library for taking pictures with the camera.
[19:57] <JWP> I use for a security camera a package called motion on raspbian. Is that suitable? or are there other packages?

[19:58] <daveake> It's trivially easy to write your own script in Python or bash
[20:01] <mfa298> you're probably best off to write something that take images at a fixed timeframe. If you use picamera there's a load of good examples at http://picamera.readthedocs.org/en/release-1.4/recipes1.html#capturing-to-a-file

[20:05] <mfa298> if you're controllign it from python I'd use the picamera library for everything as it can do everything (at least with the PiCam). It can even shoot video and output images at the same time.
[20:06] <mfa298> not something you can do with raspivid/raspistill

[20:07] <JWP> Ok great, i have a picamera here, so it will be picamera then.
[20:09] <JWP> Is there also documentation available on how to compose the telemetry sentence? I found this example, but i want to be sure i'll follow the right documentation: $$PIE,218876,09:58:31,51.51014,-1.38488,00186,0,0,8,24.1,30.0,40.1,994.14,10.05*E775
[20:09] <mfa298> Start off with a bit at a time and it should be a good learning exercise.
[20:10] <mfa298> there's not much format to it. at least 2 $ symbols, callsign, comma seperated list of fields, * checksum
[20:10] <mfa298> that link should give a fuller description
[20:10] <JWP> Yeah it does ;-) thanks
[20:10] Action: mfa298 pats zeusbot. Well done!
[20:13] <mfa298> there's a lot of good stuff on the wiki (if you can find it). Most is biased towards arduino but you use it as a guide for writing your own code in python.
[20:15] <JWP> I see it, maybe i will use a arduino uno, and a raspberry for the pictures :-) but first i will give it a go with python. Thanks!

[20:24] <aadamson> Hi mike
[20:24] simrun (~simrun@2a02:2658:1011:1::2:2178) joined #highaltitude.
[20:24] <mikestir> evening/afternoon. I have olivia up and running on my tracker board - thought you might be interested
[20:24] <mikestir> it's very impressive
[20:24] <mikestir> it will decode even when it's inaudible in headphones
[20:24] <aadamson> AWESOME!!!
[20:24] <aadamson> excellent news
[20:25] <aadamson> I saw your posts yesterday about sending the wife on a fools errand :)... did you sort that out?
[20:25] <mikestir> yeah she was going out anyway so I threw the tracker in the car and plugged it into my 2/70 antenna
[20:26] <mikestir> dominoex didn't work well at all when the car was moving
[20:26] <fsphil> tried thor?
[20:26] <mikestir> not yet
[20:26] <aadamson> beside aprs, the only other one I have functional is Thor16
[20:27] <aadamson> in theory I can do 8, etc ,but only tested 16
[20:27] <mfa298> it's a long way to get to grenwich for testing, that's where Thor is isn't it ?
[20:27] <fsphil> they made a bit of a mess, hopefully all cleaned up before the conference :)
[20:27] <mikestir> I thought olivia sounded more flexible - it has lots of knobs to turn
[20:27] <mikestir> you can set it up for a mode that's effectively FECed rtty
[20:28] <aadamson> oh joy, just what I *dont* need :)
[20:28] <aadamson> that is very cool however... excellent work/job/fun/hobby/did I cover everything?
[20:28] <aadamson> lol
[20:28] <mikestir> anyway you can change modes on the fly via a cli command</showing off>
[20:28] <aadamson> cli?
[20:28] <lz1dev> LZ1NY_: g8fjg_ron, if i am not mistaken
[20:28] <aadamson> peaked my interest
[20:28] <mikestir> yes there's a cli on the serial
[20:28] <aadamson> I can't make usb work at 2v :(
[20:28] <aadamson> ah...
[20:28] <aadamson> serial
[20:29] <aadamson> my rev2 will bring out another serial for that and to talk to a STX3 :)
[20:29] <LZ1NY_> lz1dev 10x
[20:29] <fsphil> https://www.youtube.com/watch?v=4-PIckHrZ0o
[20:29] <aadamson> so I'm bringing out a full 4 wire serial
[20:29] <mikestir> lol
[20:29] <aadamson> actually I say that, my rev3...
[20:30] <aadamson> rev2 is about to get started so I can lose some weight, and fix a few annoying things that I either missed, need or way over engineered
[20:30] <aadamson> guess in retro that was good however cuz I had flexiblity in bringing up the board
[20:32] <mikestir> the only real concern about my rev 1 is whether it will be stable enough with the 10ppm XO rather than a tcxo
[20:32] <aadamson> *can't wait* to see you find out :)...
[20:32] <mikestir> that and it's annoying that I can't do rsid, but that's rsid's fault

[21:41] <Joekul> Hi there. I live in Zurich, Switzerland, but feel more at ease in English than in German. While I am thinking of attending the UKHAS conf 2014, I am as well thinking of passing the RSGB Foundation Licence exam while there. Would anyone know if as a non-GB resident, whether I may pass that exam and obtain that licence, and whether it would "authorise" me to transmit from home in Switzerland? Thanks!
[21:41] <craag> Hi Joekul
[21:41] <craag> The UK 'Advanced' license is the only one recognised internationally
[21:41] <craag> Which is the 3rd step
[21:42] <craag> 'Foundation' being the 1st
[21:42] <Joekul> Okay, clear answer, making sense too.
[21:42] <craag> By all means you can take the exam!
[21:43] <craag> But it won't be recognised outside the UK
[21:43] <Lunar_Lander> hi Joekul
[21:44] <Joekul> Thanks. Yet, I would only if you would have less than the 6 slots you have avail

[22:09] <mikestir> what is it with consumer electronics advertising their low battery status by persistently blinking lights and beeping, thereby wasting what little power is left

[22:11] <G8APZ> probably to remind you to buy another battery before it stops blinking!
[22:12] <G8APZ> what annoys me is those tiny cells that are vital to keeping the software state in a radio......the only way to change them is to remove the cell and hence lose the memory!
[22:13] <G8APZ> when a simple solution would be to have a spare space for the replacement cell
[22:13] <G8APZ> then remove the dying one
[22:13] <mikestir> change it with the power on?
