[09:54] <Geoff-G8DHE> I listen for them occasionally now
[09:56] <PE2BZ> The company FAAM seems to be flying the MET1 today between 08 Z and 13 Z and the flightplan states that there will be sonde drops between surface and FL350

[12:47] <arjunnaha> How can you attach the GoPro to the payload box?
[12:47] <adamgreig> friction is a popular choice
[12:47] <adamgreig> duct tape and cable ties perhaps second place
[12:49] <arjunnaha> And then use the app or something to start it?
[12:49] <arjunnaha> Considering the short battery life
[12:49] <adamgreig> sure, yea
[12:49] <adamgreig> sometimes I just press the button
[12:49] Nick change: fl_0 -> fl_0|afk
[12:50] <arjunnaha> good choice
[12:50] <craag> I'd suggest avoiding using hte wifi
[12:50] <craag> it adds to battery drain, and is IMO the most buggy bit
[12:50] <adamgreig> it is good for checking your view though
[12:50] <craag> yep
[12:50] <craag> then turn it off :)
[12:51] <arjunnaha> Do you use external batteries for flights? I somehwere read that you should prepare for 3-4 hours...
[12:54] <SpeedEvil> Do actually have a checklist.
[12:54] <SpeedEvil> There are suggestions on the wiki.
[12:54] <SpeedEvil> 'press the button and check it's actually recording' should be on there

[12:54] <SpeedEvil> As people forgetting has happened
[12:55] <gonzo_> and that the SD cards are fresh and plenty of space
[12:55] <adamgreig> and the batteries
[12:55] <SpeedEvil> And tying the balloon to the payload
[12:56] <mattbrejza> and not tying the parachute upside down
[12:56] <mattbrejza> and remembering to attach the backup tracker
[12:56] <gonzo_> but the most common failute is, not making sure yoiu have GPS lock and telemetry decode at a reasonable distance from the payload, before launch
[12:57] <gonzo_> I assumes chutes would be self righting!
[12:57] <adamgreig> not if you tie them upside down!
[12:58] <adamgreig> most HAB chutes have connection points at top and bottom
[12:58] <adamgreig> bottom goes to payload, top to balloon
[12:58] <adamgreig> if you get that wrong...
[12:58] <gonzo_> ah, ok, centre connected at the top
[12:58] <LunarWork> be back later
[12:58] <adamgreig> if you only attach at the bottom of the chute it's less of an issue
[12:58] <adamgreig> (it's not an issue at all in fact)
[12:59] <gonzo_> I've only ever had the chute on a separate line, hanging free
[12:59] <adamgreig> that works, but you get more drag on the way up

[13:00] <arjunnaha> SpeedEvil: I do, I'm just asking if the stock camera time for a GoPro (Hero+ Black) is enough...
[13:01] <mattbrejza> i think the answer is generally dont count on it
[13:02] <SpeedEvil> You can get less flight time by simply winding up the amount of helium
[13:02] <SpeedEvil> It goes up faster, bursts faster, and does not go as far
[13:02] arko (~Arko@vanderse.xxx) joined #highaltitude.
[13:02] <arjunnaha> nah, I want to get decent pics
[13:02] <SpeedEvil> Your pics may not differ appreciably with the length of flight
[13:03] <mattbrejza> well for starters what is the stated battery life and what is the expected flight time
[13:03] <SpeedEvil> You just have 16000 (or whatever) not 8000
[13:03] <mattbrejza> and then remember that battery life reduces with temperture (although if anything the heat of the camera will keep it pretty warm)
[13:04] <SpeedEvil> Of course, the longer the flight, the further it goes, and the more chance you won't recover it
[13:05] <arjunnaha> What height should I be aiming for, for good pics and (relatively) easy recovery
[13:05] <adamgreig> 24km
[13:05] <adamgreig> good pics, cheap balloon, easy recovery
[13:06] <mattbrejza> well depending on the winds going another 10km might not end up with the balloon travelling futher
[13:06] <adamgreig> true but will require a more expensive balloon
[13:06] <adamgreig> admittedly depending on the winds going higher might make recovery easiest but I'd say mostly not
[13:06] <mattbrejza> we got to 30km with a 300g balloon iirc
[13:07] <adamgreig> lol
[13:07] <adamgreig> with a gopro?
[13:07] <mattbrejza> 808 + canon
[13:08] <adamgreig> nice
[13:08] <gonzo_> also winds and launch site and proximity to the sea may be a factor
[13:09] <mattbrejza> oh 500g not 300g, still was the small cylinder of He

[16:43] <NormanOK> hello everyone, I am having some problems with my payload. I would appreciate any help to figure out what is wrong with my setup.
[16:43] <mbales__> go on
[16:43] <NormanOK> here is some pictures and and a wav file: https://drive.google.com/folderview?id=0B5ydh6oJTtw5flh3ZXlWczYxeUx3M3ZDOW44dElxMHN3a3JOQTFWOTdjbFNFYWk3Z2lIWms&usp=drive_web
[16:43] <Geoff-G8DHE-M> can you post a screengrab of dl-fdigi and anyother software sdr# etc ?
[16:44] <NormanOK> yes, there are a couple of screenshots and a wav file in that link.
[16:44] <Geoff-G8DHE-M> You have Squelch turned on - needs tirunging off
[16:45] <mattbrejza> well on payload.jpg you seen to have several wires loose
[16:45] <mbales__> that is certainly a unique payload
[16:45] <NormanOK> yes, I was trying to power it from another source.
[16:45] <mattbrejza> baudrate 56?
[16:45] <NormanOK> before everything was powered over arduino's regulator.
[16:46] <mattbrejza> also any reason for the gps antenna not being straight?
[16:46] <NormanOK> no 50. I don't why the setup window shows that, but at the bottom you can see that it is set to 50
[16:46] <Geoff-G8DHE-M> seems to have a lot of drift and chirp on the signal as well
[16:46] <mattbrejza> werid
[16:47] <NormanOK> straight did not work very well, then I read that the gps is signal is polarized, so I tried to make a helix :)
[16:47] <daveake> That drift is the transmitter heating up ... how much power is it set to ?
[16:47] sumie-dh (~sumie-dh@nat.brmlab.cz) joined #highaltitude.
[16:47] <NormanOK> some of it is my rtl-sdr, just warming up. but yes there is still some drift.
[16:49] <NormanOK> for the rtty to work, is it enough for each part of signal to be within those horizontal red lines?
[16:49] <Geoff-G8DHE-M> yes its not critical on the width with such a strong signal but the spacing is a a trifle more sensitive
[16:50] <Geoff-G8DHE-M> but nothing seems awry there
[16:50] <Geoff-G8DHE-M> do you have any other filters/noise blankers or signal conditioning turned on in gqrx ?
[16:50] <NormanOK> I think I tried it without squelch, did not seem to make a big difference. I can't try it again now, because I am at work but I'll try it later. Is the first bit usually missed with squelch?
[16:51] <NormanOK> bu then at least the rest of the bits should be detected properly, no?
[16:51] <Geoff-G8DHE-M> no it will either work or not with squelch just acase of minimisning problems!
[16:51] Strykar (~wakka@ joined #highaltitude.
[16:52] <Geoff-G8DHE-M> wasn't there are problem with themore recent copies of fldigi and RTTY ? Have you tried the dl-fldigi version ?

[17:02] <NormanOK> haha yes kind of, although I've been working on it for a while now, but I am still pretty excited.
[17:02] <mbales__> very cool
[17:02] <mbales__> ill show you my current project: tracksoar.com
[17:03] <mbales__> its almost a year in the works now
[17:04] <NormanOK> looks great. I'm hoping to design my own circuit too. learning how to use eagle now. but that's gonna take some time I guess.
[17:05] <mbales__> yeah its a little up hill, but very doable
[17:06] <NormanOK> what do you use as transmitter?
[17:06] Nick change: fl_0|afk -> fl_0
[17:06] <mbales__> radiometrix hx1
[17:06] <mbales__> but there are pin compatible versions for a lot of frequencies
[17:08] <NormanOK> I see. I'm hoping to put everything together on a single pcb with si4464 doing the rf work.
[17:09] <NormanOK> I have more questions :)
[17:11] <mbales__> go right ahead
[17:11] <NormanOK> my radio is supposed to go up to 20 dbm, but doesn't work above 11 dbm. it just transmits couple of bits and stops. I was thinking it was a current issue and tried it again with a different power supply but that did not work either. is it possible that I need more than a simple piece of wire as my antenna?
[17:12] <mbales__> is your wire trimmed roughly to the correct legnth for a harmonic of the wavelength?
[17:13] <NormanOK> quarter wavelength and no ground plate. well I guess there is the ground plate of the gps receiver which probably acts as a ground plate for the radio too.
[17:14] <NormanOK> which is confusing if that's right :)
[17:14] <mbales__> hmmm
[17:14] <mbales__> do you have a way to see the current being drawn?
[17:14] polymorf_ (~polymorf@ left irc: Remote host closed the connection
[17:16] <NormanOK> yes I checked the current, it was about 35 mA for 11 dbm and goes up with higher tx power settings or at least initially, then stops transmitting or transmits at a much lower power.

[17:19] <NormanOK> yes I checked the current, it was about 35 mA for 11 dbm and goes up with higher tx power settings or at least initially, then stops transmitting or transmits at a much lower power.
[17:19] <NormanOK> I guess i replied before your irc client crashed.
[17:29] <mbales_> ah ok
[17:30] <mbales_> and which module are you using again?
[17:30] <NormanOK> I also have some questions on balloons. I did some back of the envelope calculation and estimated the floating altitude in terms of r = (payload weight) / (maximum balloon lift). so for r = 0.5 I got, 4-6 km and r = 0.1, 11-15 km. would you agree with those numbers?
[17:31] <NormanOK> it's a cheap module based on si4432. here is the ebay link: http://www.ebay.com/itm/SI4432-470MHz-1000m-Wireless-Communication-Module-470M-433mhz-/181351297487?pt=LH_DefaultDomain_0&hash=item2a396131cf
[17:37] <mbales_> for predicting just about everyhting i really like this site: http://astra-planner.soton.ac.uk/

[17:40] <NormanOK> thank you very much!
[17:41] <mbales_> what voltage are you running everything on?
[17:41] <NormanOK> 3.3V
[17:43] <mbales_> that ll looks good, what are you using to power it?
[17:45] <NormanOK> I was using arduino pro mini's regulator and a 200 mAh lipo battery.
[17:46] <NormanOK> I don't use gps and radio simultaneously, so I think 150 mA supplied by that regulator should be enough to power everything.
[17:47] <mbales_> i wonder if there is a quick pulse when it starts transmitting and that puts it into a reset state
[17:48] <mbales_> do you have access to an oscope to check that?
[17:48] <NormanOK> hmm maybe, but I also tried to power it directly from two AA batteries and that did not seem to make a difference.
[17:49] <mbales_> maybe try that with a decoupling cap and see if that helps, maybe theres a decent sized ripple
[17:49] <NormanOK> no oscilloscope unfortunately :(
[17:49] <mbales_> sad face indeed
[17:51] <NormanOK> OK, good idea, I'll try that in the evening. one last question! could you try to see if you can decode my rtty recording?
[17:51] <mbales_> can you send the link again?

[17:52] <mbales_> what modulation are you using?
[17:52] <mbales_> sorry ignore that
[17:53] <NormanOK> it is supposed to be 50 baud, 290 hz, ascii-7, two stop bits no parity bit.

[17:58] <mbales_> oh wait, let me try with my phone
[17:59] <NormanOK> ok, maybe another time. I'll see if I can catch you online later today. thank you for all the help!
[17:59] <NormanOK> oh ok :)
[18:00] <NormanOK> which app do you use?

[18:59] <chimpusmaximus> I'm currently working on a controlable trigger for both focus and shutter on a sony RX100 MkII. I have found that its possible to get an aftermarket cable that outputs the shutter and focus to a 2.5mm stereo male pin.
[19:00] <chimpusmaximus> If i then ground each of the connections i can control the shutter and focus. I was thinking to use two Optocouplers to allow me to pull a pin high on say an arduino and then control the focus and shutter timeings.
[19:00] <chimpusmaximus> Does this sound sensible?
[19:01] <ike> how do you controll focus with only one pin?
[19:02] <chimpusmaximus> It just forces auto focus to kick in.
[19:03] <ike> then can you hold it to GND all the time?
[19:07] <chimpusmaximus> for focus i dont think it liked it when i tried. Been a while sinc ei tested but i think i had to pull focus high for about 1.5 seconds and then trigger the shutter.
[19:07] <chimpusmaximus> As far as shutter i wanted some control over how often and at what altitude it took photos.
[19:08] <chimpusmaximus> A 9g servo was another option.

[19:14] <NormanOK> dbrooke: OK, thank you very much! I've been using a sample code I found online. it runs delayMicroseconds(10000); delayMicroseconds(10150); for 50 baud. I am not sure why it does more than 20 ms delay, but I was assuming that it's a well tested code. Or maybe there is some other things causing a timing error.
[19:30] <dbrooke> I'd have expected that a delay would need to be less than 20ms, to allow for the execution time of the code between the calls to delay, whereas that seems to delay for longer.

[19:47] <NormanOK> dbrooke: great idea, I guess I can also fine tune the timing that way.
[19:51] <dbrooke> hopefully, dl-fldigi is not very tolerant to timing error so you're probably not too far off anyway
[19:53] <day> Oddstr13: is it possible to increase the resolution of the waterfall so far that i can look into the packages?
[19:53] <Ian_> NormanOK no one seems yet to have commented about fldig3.png but here are my observations and recommendations:
[19:54] <Oddstr13> day: probably not
[19:54] <day> because those 3data blobs. 3x the same
[19:54] <Oddstr13> can I have an AM recording of a burst of three?
[19:54] <day> the raw one sounds much cleaner
[19:55] <day> but yeah sure
[19:56] <Ian_> Why baud rate of 56 Baud and not 50? Parity even, should be parity NONE. which might be very significant. Normally 8 bit ASCII and 1 stop bit or 7 bit ASCII and 2 stop bit..
[19:56] chimpusmaximus (~Chris@host217-46-69-167.range217-46.btcentralplus.com) left irc: Quit: Leaving
[19:57] <Ian_> The difference in length and stop bits is probably mute. You might need 8 bit if using ssdv but normally straight telemetery needs only 7 bits.
[19:57] stucky_ (~stucky@ip2504bc3c.dynamic.kabel-deutschland.de) joined #highaltitude.
[19:58] <Ian_> Shaped TX probably is of no concern and Unshift On Space is a Baudot type TTY feature of some US Mokrum or Teletype Corp Machines. not used in the UK at all (historical note)
[19:58] <NormanOK> Ian_: I don't know why fldigi was showing those settings but below it says 50 baud for example. sometimes when I try to go back and change the settings it shows me the default ones.
[19:59] <Ian_> Hope some of tha might help
[20:00] <NormanOK> ok I see, I didn't know what those were, I was playing around to see if any one them would help.

[20:00] <Ian_> I can only make the observations NormanOK. I'm surprised that no one picked up on the parity issue, particularly when you were getting some apparent correct characters but not others - parity issue.
[20:00] <day> Oddstr13: how do you figure out which protocol is being used? i guess each protocol has a distinctive sound?
[20:01] <Oddstr13> day: my AV actually blocked that download for some reason
[20:01] <Ian_> I think that parity was a rarely used TTY feature and certainly a PITA when companies implemented it to talk to their particular devices.
[20:01] <day> its a wav file o0
[20:02] <day> Oddstr13: want me to upload it somewhere else?
[20:03] <Oddstr13> dropbox usually works fine
[20:03] <Ian_> What protocol How to detect? 50 Baud sounds like 50 Baud. 7 Bit the Rx is ready to go after bit 7 (the tx supplies the async stop bits to allow the rx to be ready for the next character if there are minor timing probs due to propagation, line delay etc).

[20:06] <NormanOK> ok I see, maybe I was not able to set all the options right. I'll double check everything. Is there a guide on how to install dl-fldigi on ubuntu? apt-get install dl-fldigi complains that libxmlrpc-c++4 is not installable.

[20:07] <day> oh. its not a hab signal. im just playing around trying to understand how to approach the whole radio thing
[20:07] <Ian_> I would have thought 8N1 or 7N2. Unless needing to tx binary then I would go for 7N2 but then I'm a biased ex-teleg
[20:07] Geoff-G8DHE-Tab (~Geoff-G8D@geoffg8dhe.plus.com) joined #highaltitude.
[20:08] <Ian_> For general use then 8N1 will maybe keep your options open.
[20:08] <Ian_> Can't help you with dl-fldigi I'm afraid.
[20:08] <day> and how do i figure out if its ook/fsk/.....
[20:11] <Ian_> With your ears I guess. Oh in RTTY.wav if you are generating that signal I would start with a short holding mark before actually starting the character transmission. That way the receiver gets a chance to settle and the rx to be ready for the start of a new character,

[20:12] <Ian_> If the rx receives noise and is half way through a character when the tx starts, you tell me how long it might take for the rx to be able to resync correctly with a worst case data pattern and only one stop bit? Hmmmm

[20:14] <day> Ian_: are you using the one i posted previously?
[20:14] <day> because they are the same
[20:16] <Ian_> I was looking at the one supplied by NormanOK but will look at your download-10785885 now
[20:16] <day> ah ok. didnt see that someone else posted a file as well :)
[20:16] <NormanOK> Ian_: how many $'s is often used for that? I was using 3 of them.
[20:17] <day> i would guess mine has roughly a baudrate of 150
[20:17] <day> and i think the freq. is changing :/

[20:19] <Ian_> Normally two are needed, but often there are three or four transmitted with all but the last two having throw away status. checksum parsing software on the tx side should throw away the right number to be able to work OK

[20:21] <Upu> hasn't been heard from in 23 hours fox123
[20:22] <Ian_> day - your signal is obviously OOK from the waveform noise and then quietening with clicks. from data? You would do better to use FSK, but with OOK you will find that an AM mode will give you better reception than trying to get sense with SSB. Something that actually isn't intuitive to me.
[20:24] <day> Ian_: did you look at it in audacity/
[20:24] <Ian_> Yes
[20:24] <day> is each of those spikes just a single bit?
[20:24] <day> because it sounds like many more
[20:24] <Ian_> Pass, each of those bits is a transition from one state to the other
[20:24] <Ian_> I would say
[20:25] <Ian_> did say
[20:25] <Ian_> do say
[20:25] <day> that means there are only 5bits in each package?

[20:32] <Ian_> day - Beyond me to be able to say, but in the apparent quieting there is data. What the blips "possibly" mean is that the data patterns allowed a larger excursion in the perceptual waveform received.
[20:33] <day> Ian_: yeah thats what i think as well. theres a lot of beeping in the quiet areas
[20:33] <Ian_> OOk is probably OK for very local stuff, but pushing it a bit for HAB I suspect.

[20:39] <day> yes. my guess is 150baud
[20:39] <day> but i have no reference
[20:41] <Ian_> Your reference is the txr. What is producing the signal?
[20:44] dl3yc (~yc@ left irc: Ping timeout: 260 seconds
[20:44] <day> just an unknown push button. something i found lying around. could be part of a toy for all i know
[20:45] <Ian_> Ah, the afore said wireless push button - I was thinking that was YOUR application, but obviously now you are listening to the output, which may or may not be ASCII of course. it might be proprietry coding
[20:45] <day> nono
[20:45] <day> looking at the signal im pretty sure its sending 3x the same package
[20:46] <day> each of the packages is fragmented into 6 packages of 35ms seperated by 16ms
[20:46] <Ian_> Should be possible to cut and paste in Audacity and overlay one with the other (almost) to confirm the sameness of the packets. Is there anything in the switch that might suggest /
[20:47] dl3yc (~yc@ joined #highaltitude.
[20:47] <Ian_> that it can be set, factory or otherwise, to a particular identity - jumper blobs etc?
