[00:05] <SpeedEvil> I question the word stolen.
[00:13] <Ian_> I am unsure if the man was charged, but hadn't apparently made any attempt to actually contact the owner.
[00:14] <Ian_> Removed from the scene is perhaps a more diplomatic interpretation subject to confirmation.
[00:14] <Ian_> Theft by finding perhaps?
[00:15] <SpeedEvil> I misremembered the law. nvm.
[00:16] <Ian_> If my memory serves me well, a caution was issued and the property restored to it's legal owner.
[00:17] <SpeedEvil> yes, in the circumstances above, theft applies
[00:18] <SpeedEvil> I was entirely wrong
[00:20] <Ian_> Not a problem, a discussion item. I'm not likely to get phases by another opinion and I'm sure you won't get too excited either. :)
[00:20] <SpeedEvil> If there wasn't a label on it, then the distinction is very unclear
[00:21] <SpeedEvil> and it's quite arguably reasonable to hand it into the police and get it back after several weeks
[00:21] <SpeedEvil> s/arguably//
[00:23] <Ian_> Worth putting a uniqe web page URL on the label though as access indicates that the label has been read. I believe there was the URL and a telephone number. the state of the package when interviewed would likely establish if there was any intention of returning the camera and electronics
[00:24] <SpeedEvil> yeah
[00:24] <Ian_> Camera secreted among own posessions, away from the package.
[00:26] <Ian_> You would normally have to give the benefit of the doubt of course, but I think around a week had passed. I must check during the day to see who's package it was. One of the regulars IIRC

[10:16] <x-f> hey, michemto, just saw your launch announcement, i will pass it on to our trackers and will try to help with the tracking
[10:19] <michemto> Hey, thats nice!
[10:19] <michemto> Thanks - please inform your contacts in Latvia (am I correct?) too :)
[10:20] <x-f> you are correct :)
[10:21] <x-f> given the fairly long flight path i would suggest you start chasing immediatelly after launch, or even better would be to deploy a recovery team near the predicted burst area
[10:22] <michemto> Yeah, we already have 3 chase-cars and one will start following right away... with a scanner on its board, so we will try to get data on our own too :)
[10:22] <michemto> This prediction is getting every day closer to the lake :D
[10:22] <x-f> you can overfill the balloon a bit if that helps
[10:23] <Vaizki> where are you launching?
[10:23] <Vaizki> estonian lake dive again?
[10:24] <x-f> i hope not this time, and that was Russian lake back then..
[10:25] <Vaizki> they stole our lake too :(
[10:27] <x-f> michemto, please, let us know if you decide to shift the launch time to an earlier hour
[10:27] <x-f> good luck with the launch and have fun!
[10:28] <SA6BSS-Mike> when i this launch?
[10:28] <day> michemto: what kind of data are you trying to collect_
[10:29] <michemto> Vaizki, where are you from? http://puu.sh/hV8Wv/4d26e89070.png
[10:29] <michemto> Oh yes... I was involved with that earlier "Ilmapall" flight too... but we couldn't postpone the launch because it was opening event for meteo station.
[10:30] <michemto> x-f, I will!
[10:30] <michemto> SA6BSS-Mike, 23.05.2015 09:00UTC hopefully...
[10:31] <michemto> From Estonia. Flight will appear in calendar soon - will have to turn on the Pi because we did last changes in payload doc before entering flight.
[10:31] <SA6BSS-Mike> ok, I´m at work the, else I shoud hve driven to a hill with a ygi havin a listen
[10:31] <SA6BSS-Mike> Vaizki is located in suth Finland
[10:33] <michemto> Damn... We definitely need guys in Finland because payload will go somewhere in the North-Estonia...

[13:41] simium (2e181462@gateway/web/freenode/ip.46.24.20.98) joined #highaltitude.
[13:41] <simium> hi all
[13:43] <craag> afternoon
[13:43] <simium> what's the experience on sending up payloads without insulation? You know, bare electronics, even if they are industrial grade (down to -40ºC)
[13:44] <craag> If you're doing it in sunlight, they're unlikely to get near -40.
[13:44] <gonzo_> lots of people do. (I thibnk all Leo's ones were uninsulated)
[13:44] <craag> Also there's no conduction of heat, so any heat they generate themselves will warm them up
[13:44] <simium> as per my research, everybody assumes you need insulation to protect the electronics from the cold temperatures, but afaik sensors usually measure -40 ºC or more, so we'd be just pushing the limits of the electronics, but not too much...
[13:45] <eroomde> everyone is wrong
[13:45] <simium> aha
[13:46] <eroomde> those sensors are often measuring their own temperature rather than air temperature
[13:46] <eroomde> and as you say, that's often above air temperature
[13:46] <simium> I see
[13:48] <simium> let's assume we fly some industrial grade hardware
[13:48] <eroomde> industrial grade hardware == hardware whose temperature rating is 'industrial'?
[13:48] <simium> will it be damaged by the cold temperatures? will it just reset until temperature is better then it will fix itself?
[13:49] <simium> eroomde exactly, yeah
[13:49] <eroomde> depends on what the hardware is
[13:49] <simium> (I'm sorry, English is not my mother tongue)
[13:49] <eroomde> the physical limits on temperature are usually not to do with mechanical damage
[13:49] <eroomde> silicon stops semiconducting beneath about -55
[13:49] <simium> assume a basic arduino+rf module
[13:50] <eroomde> it should be fine. things to worry about are, for example, crystals on the rf module that are not temperature-compensated
[13:50] <eroomde> meaning your transmission frequency drifts about with temperature
[13:50] <simium> ok
[13:51] <gonzo_> packaging the electronics close the the batteries, with a small amount of insulation should help. As the batteries will give some thermal mass.
[13:51] <simium> is it safe to assume a "cold dark zone" where everything is too cold but then we are back to safe hot weather and everything starts wortking again?
[13:52] <eroomde> no
[13:52] <eroomde> no one is saying the electronics will stop working in the cold
[13:52] <eroomde> we are all saying that they'll probably carry on working
[13:52] <gonzo_> And seal it to stop air movement from heating/cooling components
[13:52] <simium> oh, ok
[13:53] <gonzo_> how many times have we actually seen a payload fail/malfunction, due to cold?
[13:53] <simium> I've flown a balloon once, in september, it worked like a charm, but it had a 3-cm wall box of extruded foam around
[13:53] <SpacenearUS> New vehicle on the map: 03HL1 - 12http://tracker.habhub.org/#!qm=All&q=HL1
[13:54] <simium> I was thinking about making something more cubesat-like
[13:54] <simium> bare electronics and to infinity and beyond (only to crash again)
[13:54] <eroomde> gonzo_: once but i think that was due to the micro's internal osc drifting too far from the gps's such that the nmea strings stopped decoding
[13:54] <eroomde> also crap battery chemistries but that's easily avoidable by using the right batteries
[13:54] <gonzo_> the main failure for payloads seems to be software bugs and gps failure (not in flight mode, or wrong choice of GPS module)
[13:55] DL7AD (~quassel@p4FD43563.dip0.t-ipconnect.de) left irc: Read error: Connection reset by peer
[13:55] <gonzo_> Oh, and releasing a payload without checking it's actually working 100%
[13:56] <simium> my flight only failure (ahem) was the GPS stopped updating altitude after 200m or so
[13:56] <eroomde> ouch
[13:56] <simium> I was using adafruits GPS, it should have worked flawlessly but I don't know why the issue with altitude
[13:57] <craag> I've also seen that on an adafruit gps
[13:57] <simium> (couldn't find anything about "setting it to flight mode")
[13:57] <craag> it seemed to revert to a 2d lock
[13:57] <craag> Use ublox next time ;)
[13:57] <simium> Oh I see
[13:57] <simium> I've heard a lot of good things about the venus modules
[14:00] <eroomde> they're alright
[14:00] <eroomde> dynamic performance isn't great
[14:00] <eroomde> but alright for ballooning

[21:42] <michemto> From PITS?
[21:42] EwanP (~yaaic@cm-84.210.25.93.getinternet.no) joined #highaltitude.
[21:43] <hiflyer_> no, just using an ntx2 - works fine using digital pins but I've heard you can use the uart which is much simpler
[21:45] <daveake> yes you can
[21:45] <Upu> Assume you're using a mega
[21:45] <hiflyer_> yep
[21:45] <Upu> which is 5V logic
[21:45] <Upu> the NTX2B max input is 3V
[21:46] <Upu> on TXD
[21:46] <hiflyer_> ah, any ideas?
[21:47] <Upu> use the resistor network method you can pull the voltage down to an acceptable level and then just toggle high and low
[21:47] <Upu> or use a level convertor
[21:48] <daveake> There's absolutely no electrical difference between using the uart and doing it in software with an output pin
[21:49] <hiflyer_> thanks, is the code just Serial1.begin (50,SERIAL_7N2); and Serial1.print("RTTY TEST"); ?
[21:51] <daveake> yes ofc
[21:52] <hiflyer_> for some reason it isn't working - no discernable rtty coming out
[21:54] <daveake> check your wiring then
[21:54] <Geoff-G8DHE> Are you checking the serial port or the Radio output ?
[21:55] <hiflyer_> radio output, ive just got tx1 going to the ntx2 tx pin
[21:55] <Geoff-G8DHE> Has it worked before ?
[21:55] <hiflyer_> ive never used the serial on the ntx2 but it works perfectly using the output pins
[21:57] <Geoff-G8DHE> Are you able to check the serial output with a scope or connect it to another serial port on another computer ?
[21:58] <Ian_> If you are breadboarding, use a small resistor/sounder to check the output sounds convincing if you haven't got a scope or just for a first look. Always good to have a suitable resistor/LED combo for checking things too.
[22:00] <daveake> yeah an led/R will quickly show if it's sending out of the serial port
[22:00] <hiflyer_> ive tried all the serial tx pins on my mega and its not working on any of them
[22:01] <hiflyer_> just seems a bit odd
[22:02] <daveake> OK, appears 50 baud not aupported
[22:02] <daveake> See http://www.arduino.cc/en/Serial/Begin
[22:02] <daveake> cancel that

[22:03] <daveake> Says "You can, however, specify other rates"
[22:03] <Geoff-G8DHE> but it doesn't specify what is valid :-(
[22:04] <hiflyer_> let me try 300 baud
[22:04] <Ian_> Seems to start at 300 Baud, surely why it had been bit banged in the past at 50 Baud
[22:04] <daveake> yeah 50 might be to low for the baud rate dividers
[22:04] <hiflyer_> yep
[22:04] <hiflyer_> works lol
[22:05] <daveake> Ian_ The bitbanging is because the UART is used for a GPS
[22:05] <Geoff-G8DHE> "You can send at lower or higher rates (the range is 300 to 115,200), but make sure both sides use the same speed"
[22:05] <Ian_> Good point daveake
[22:05] <Geoff-G8DHE> https://www.safaribooksonline.com/library/view/arduino-cookbook-2nd/9781449321185/ch04.html
[22:05] <daveake> Next step then is to check the h/w ref manual
[22:06] <hiflyer_> is this a problem - are higher baud rates less reliablr?
[22:08] <Geoff-G8DHE> Yes bandwidth/noise trade off
[22:08] <hiflyer_> would you say 300 is ok for hab?
[22:09] <Geoff-G8DHE> Without FEC as used with SSDV you will be pushing limits
[22:09] EwanP (~yaaic@cm-84.210.25.93.getinternet.no) left irc: Ping timeout: 256 seconds
[22:09] <SpeedEvil> 300bps is just fine
[22:09] <SpeedEvil> fsphil did several flights IIRC
[22:10] <daveake> Remember you get 6 x the number of packets, so the odd loss doesn't matter
[22:10] <Ian_> It has to be OK as the PISKY uses it, but the range and reliability is likely to be a limiting factor. Mileage will vary of course
[22:10] <hiflyer_> for safety i think i may just revert to 50 baud on the output pins
[22:12] <hiflyer_> still can't find anything about the lowest baud rate on the serial interface
[22:12] <michal_f> does PITS send telemetry and images with he same baud ?
