[11:07] <Geoff-G8DHE> Did the payload report the speed? If so its what was specified in the payload document
[11:08] <garymortimer> you can see the position changing, is it not showing because the min num of sats is not achieved?

[11:09] <michemto> Well... unit is km/h i guess

[11:09] <garymortimer> so do folks now log the positions and do things handraulically
[11:09] <garymortimer> yeah i see that craag, I guess thats an altitude issue as well

[11:09] <craag> Yep surprising it's still reporting a changing position with that few satellites
[11:10] <craag> Altitude usually helps gps
[11:10] <craag> your horizon gets a lot lower :)
[11:10] <craag> hmm maybe a payload bug
[11:10] <craag> maybe it's reporting 12 satellites, but is cutting the '1' off
[11:11] <garymortimer> Its current position is in the region of Gamblingay
[11:13] <craag> garymortimer: Is the altitude still changing? (that's usually a sign of good 3d lock)
[11:14] <garymortimer> No it snot, I have a hunch its turned so perhaps descending could be utterly wrong
[11:15] <craag> It's a navspark gps
[11:15] <craag> According to the payload doc
[11:15] <craag> And filter for valid fix when gps_satellites > 3
[11:16] <craag> So might well be an altitude problem tbh

[11:48] <daveake> Nothing uploaded at all during flight
[11:49] <AdamDynamic_> Which suggests it went wrong on the ground?

[12:52] <Babs____> Yes infaddict - it's running all of the software for my active stabilisation tracker but is lighter on the hardware - can test it a lot easier that way because I can launch in London

[12:53] <Geoff-G8DHE-M> I am
[12:53] <infaddict> Looks great Babs____, nice and light too. A pico is next on my list to design I think
[12:54] <Babs____> Hey geoff - your pano software - it couldnt take the bearing being output and put a line out from the payload on the graphic could it? The bearing should be to the eiffel tower all being well
[12:54] <Babs____> Thanks infaddict
[12:54] <Babs____> I shamelessy stole the look of it from leo and anthony
[12:55] <infaddict> efficient shape i think
[12:55] <Geoff-G8DHE-M> Not quite sure what you mean Babs cn you expand a bit ?
[12:55] <infaddict> like draw a line from payload to the ground at a given bearing of say 247 deg
[12:55] <infaddict> ?
[12:56] <Geoff-G8DHE-M> On th fly or after the event ?
[12:56] <Geoff-G8DHE-M> its onloy done using KML files in GE
[12:56] <infaddict> mmm and how long to make the line (or the angle of descent required)... guessing you would know the lat/long of the target so some maths could get that.
[12:58] <Babs____> Ahhh ok then not - Geoff-G8DHE
[12:58] <infaddict> you can draw lines in kml pretty easy tho
[12:58] <Babs____> Would be cool to see the bearing line being tracked on the tracker somehow
[12:59] <Babs____> Infaaddict - all of the distance etc is in there with a bit of trigonometry
[12:59] <Babs____> Bearing is bearing to the Eiffel Tower, pitch is angle from horziontal
[12:59] <infaddict> ok, kml supports drawing lines either flat, or also with altitude
[12:59] <Geoff-G8DHE-M> let me have a play, I'm trying to work out what/why you want to achieve this.
[12:59] <infaddict> some examples: http://dagik.org/kml_intro/E/line.html
[13:00] <PE2G> !dial lardy-pico

[13:00] <infaddict> so Babs____ if your tracker was say 30,000m would you want the line to point down to the Eiffel tower on the ground, or just horizontal from the tracker altitude?
[13:00] <Geoff-G8DHE-M> yes drawing the line isn't the problem doing it on the fly is another matter as its being fed from habhub.
[13:01] <Babs____> Point to it
[13:01] <infaddict> mmm so can any sentence variable be used Geoff-G8DHE-M?
[13:01] <infaddict> i.e. Babs____ passes habhub the data in the sentence
[13:01] <Babs____> Eventually the bearing and pitch number will swivel and tilt a camera to look at a point on the ground
[13:01] <Geoff-G8DHE-M> No there isn't any variables as such it would need to be processed after arrival
[13:02] <Babs____> In this case the Eiffel Tower
[13:02] <Babs____> Quite cool that it should go near it
[13:02] <infaddict> right, so thats the problem to solve i think, getting the data to Geoff-G8DHE-M
[13:02] <Geoff-G8DHE-M> Well that data is already availabe using craggs rotator program
[13:02] mclane_ (~quassel@p5498C10D.dip0.t-ipconnect.de) left irc: Remote host closed the connection
[13:02] <Geoff-G8DHE-M> my aerials move and point at the payload as it flys
[13:03] <Babs____> We should see the haversine bearing change quite rapidly at that point
[13:03] <infaddict> thats very cool Geoff-G8DHE-M
[13:04] <Geoff-G8DHE-M> Its also available in spacenear.us when you load your location the bearing elevation and distance are given in the top left corner
[13:05] <infaddict> so if you setup a listener at the lat/long of the eiffel tower, you'd get it
[13:05] <Geoff-G8DHE-M> yes
[13:05] <infaddict> interesting
[13:06] <Geoff-G8DHE-M> that's why I wanted to understand it better as it already exsists!

[13:11] <Babs____> What it calculates but is not tx ING is distance to target
[13:11] <infaddict> if target was the listener then those figures are azimuth, elevation & distance to target arent they?

[13:11] <Geoff-G8DHE> Yes not quite sure what Babs means
[13:13] <craag> Babs____: You transmit altitude to the nearest millimetre, but yet only 4 d.p. of lat/lon?
[13:14] <craag> (which is a few meters resolution iirc)
[13:15] <Babs> craag - its more a consequence of how the data comes out of the NAV-PVT string that i poll the ublox with
[13:15] <Vaizki> if I was really anal I would comment on that being dependant on your latitude :)
[13:15] <Geoff-G8DHE> craag would you have time to play with habrotate to output a simple KML file to a port on request, then GE can just callit every few seconds ... job done
[13:16] <Babs> but i agree, it is a little inappropriate (I am an applied maths grad so have no excuse)
[13:16] <craag> Geoff-G8DHE: KML file of what?
[13:16] <craag> The positions?
[13:16] <Geoff-G8DHE> the line between position and target

[13:16] <craag> ?
[13:16] <Geoff-G8DHE> that's it
[13:17] <craag> Only the latest one, no history?
[13:17] <Babs> by eye, that haversine bearing calc looks like quite a good line to paris

[13:18] <Babs> if i hooked up a laser canon i could do what roger moore failed to do and take out Mayday at the top of the tower
[13:18] <craag> As a kml text file that gets updated with each new position?
[13:18] <Geoff-G8DHE> thats it
[13:18] <Geoff-G8DHE> GE can use a network link to request the file and then it displays it.
[13:19] <craag> err network link?

[13:19] <Geoff-G8DHE> what Google Earth calls it a URL called on a timed basis which returns a kml file
[13:19] <craag> Oh you want a URL
[13:20] <craag> I'd build something new for that - would be fatter than habrotate by itself probably
[13:20] <Geoff-G8DHE> No your program makes a KML file avaiable on a port (any) GE then calls the port and requests the file every x seconds
[13:20] <craag> Very easy to code - wouldn't be able to build it for windows today though
[13:20] <Geoff-G8DHE> you program returns the latest file
[13:20] <Geoff-G8DHE> no I appreciate!
[13:20] <craag> You mean a http url right?
[13:20] <Geoff-G8DHE> that's it
[13:20] <craag> not a file..
[13:20] <craag> ok
[13:21] <Geoff-G8DHE> well it returns the file
[13:21] <Geoff-G8DHE> same as this line http://spacenear.us/tracker/datanew.php?format=kml&vehicles=ecc1;cheapo;spark;lardy-pico;ux2;e3spce
[13:22] <Geoff-G8DHE> it returns a KML file with those payloads flight paths in the file
[13:22] <craag> Ok, I take it onl a windows build is useful to you?
[13:22] <craag> *only
[13:23] <Babs> think we have it floating

[13:36] <dbrooke> habrotate says Balloon Azimuth: 349.0 Elevation: 0.0 at 291.4 km. from Eiffel Tower so reciprocal is 169
[13:37] <dbrooke> payload says 168
[13:38] <Babs> i'll take that 0.66% error
[13:38] <dbrooke> should pitch match elevation?
[13:39] <Babs> yes, in theory. so the 4 degrees is a bit confusing. may need to look into it
[13:39] <dbrooke> OK, it'll be interesting to see as it passes nearer
[13:40] <Babs> yes exactly. it was targeting the london eye yesterday so quite a fortuitous target change at 2300hrs last night
[13:40] <Babs> ahhh. now looks to be going nowhere near it
[13:40] <Geoff-G8DHE> Ah I see its the center of the shadow you want to point at ?
[13:41] <dbrooke> can someone set up a hysplit for lardy-pico now it's floating?

[13:41] <Babs> hi geoff, so a quick explanation
[13:41] scrapit85 (~scrapit85@248.103.115.87.dyn.plus.net) joined #highaltitude.
[13:42] <Babs> i want to send up a balloon in 2017 and get a camera up there pointing at the shadow of the eclipse
[13:42] <Babs> i use my board to generate the elevation and bearing that i want the camera to be pointing at
[13:42] <Geoff-G8DHE> yup, I'm with what your trying to do now
[13:43] <SpeedEvil> Just trying to roughly point isn't that hard
[13:43] <SpeedEvil> and can be done quite well with stock RC servos, and a simple flag on a stick to stop fast rotation
[13:43] <Geoff-G8DHE> are you aiming to track the shadow, or just a fixed position in time ?
[13:43] <Babs> it is if you want to keep it stable
[13:43] <SpeedEvil> If you're happy with photos, or video that you can correct motion in later, it's easy
[13:44] <Babs> stock RC servos don't move quickly enough to cope with bumping around in wind
[13:44] <SpeedEvil> For video that needs to remain rock steady - it's a lot harder
[13:44] <SpeedEvil> Babs: there is approximately no wind at altitude on a balloon
[13:44] <Babs> so i link it up to one of these https://www.youtube.com/watch?v=QLd5eeHqAY0
[13:45] <Babs> yes, but you also have nothing to provide a fixed point to turn around
[13:45] <SpeedEvil> that is why you have a flag on a stick
[13:45] <SpeedEvil> that keeps you at a constant orientation - pretty much

[14:14] <chrisstubbs> thanks for tracking all
[14:15] <craag> Looks like Babs is truncating the azimuth rather than rounding it
[14:15] <Geoff-G8DHE-M> check with Babs as I get the impression its a one off .....
[14:18] <craag> Also I've consistently got a pitch of -2.7, his telem says '4', I assume meaning -4
[14:18] <Geoff-G8DHE-M> all though I can see a use for it to indicate whether a path is LoS or not if it cuts a hll etc.
[14:18] <Geoff-G8DHE-M> hill
[14:19] <craag> You want me to write a radio path topographic survey application for you Geoff-G8DHE-M ? ;)
[14:19] <Geoff-G8DHE-M> Yup you got it one ;-)
[14:20] <Geoff-G8DHE-M> I actually have that already for my location it plots it out to 400Km radius!
[14:20] <craag> There are plenty of tools already

I have it at home now still running, the camera LED is flashing so may still have captured some images. Its a Pi model A with HDMI disabled, is there anything I can check debugging wise before I power it off?
[14:21] <Geoff-G8DHE-M> not had a need for the web version todate
[14:22] <craag> chrisstubbs: WHat's the battery voltage?

[17:52] <jet_> Okay
[17:52] <jet_> I'll try the antenna that came with the dongle
[17:52] <jet_> Should I be able to pick up commercial radio?
[17:53] <Vaizki> yes you can pick up broadcast fm with your eyebrows if you want..
[17:53] <Vaizki> the signals are usually very very strong
[17:53] <jet_> Well, I tried tuning into 105.400.000 for magic FM and nothing came up on wfm
[17:54] <Vaizki> did you turn up the RF Gain in settings?
[17:54] <Vaizki> the little gear icon in the SDR# toolbar
[17:54] <dbrooke> Vaizki: yes, rather like that 8-)
[17:54] <jet_> No...? Should I?
[17:55] <es5nhc> Unless you live next to a blowtorch transmitter, yes
[17:55] <prog> "Should I" hmm.7
[17:55] <prog> no you shouldn't
[17:55] <jet_> How much should i turn up the rf gain by?
[17:55] <Vaizki> until you hear stuff :)
[17:55] <Vaizki> the spectrogram / waterfall will update in real time
[17:55] <Vaizki> so you don't have to close the dialog when tweaking
[17:56] <chrisstubbs> Could anyone that watched Steve's live stream today please give a quick bit of feedback? (quality of video/audio, dropouts etc)
[17:56] <prog> "but but but they told me SDR is simple, and what you are saying looks too complicated"
[17:56] <Vaizki> prog, behave :)
[17:56] <jet_> Oh my god... I had no idea
[17:56] <jet_> Thanks so much...
[17:56] <Vaizki> newbies are good. I was a newbie in January.
[17:57] <Vaizki> jet_: np, it's usually a small thing ;)
[17:57] <jet_> This is crystal clear radio... what am I listening to now? TFL ad
[17:58] <prog> that's what she said
[17:59] <Vaizki> if you feel like an american president trying to fly a UFO, first turn off the TV and then consider reading up a bit on how superheterodyne receivers work and how SDRs use ADCs and and.. :)
[17:59] <jet_> Now when I plug in/out the antenna, I actually get a signal difference.
[17:59] <jet_> Omg absolute radio lol...
[17:59] <jet_> 49.6db gain..

[17:59] <Vaizki> omg bbq flank steak lol and aubergines with ginger & honey
[18:00] <Vaizki> om nom nom dinner
[18:00] <Vaizki> that's a bit of gain that is.
[18:01] <jet_> Well that tip about the gain was hella useful.
[18:01] <Vaizki> I can hear broadcast FM very very well with 4dB of gain
[18:02] <jet_> 32.8 and it still works
[18:02] <prog> use the minimum that works
[18:02] <jet_> What's wong with super high gain?
[18:03] <Vaizki> remember that +3dB is the same as 2x
[18:03] <dbrooke> I don't use SDR# but with gqrx and my RTL-SDR about 30dB LNA gain is where the noise floor starts to rise at UHF
[18:03] <Vaizki> jet_: does your stereo start distorting the sound when you turn it all the way up?
[18:03] <jet_> Jeez this is amazing... believe me if you haven't done this before I was shocked when I picked up absolute radio
[18:04] <jet_> No real distortion until I go super high gain
[18:04] <jet_> But it goes bad again when I turn it down
[18:04] <Vaizki> yea well you don't want your signals to clip either
[18:05] <jet_> I notice after about 10 mins of use the sdr gets a little warm
[18:05] <jet_> Is that normal?
[18:05] <prog> then began a long journey of learning
[18:05] <Vaizki> well it drains power and does not produce light or radiation
[18:05] <Vaizki> so let's agree that it produces heat
[18:06] <jet_> ik, but running hot won't damage it right?
[18:06] <Vaizki> if it doesn't smell or feel uncomfortable to the touch, no
[18:06] <prog> thousands of people use your exact same setup everyday
[18:06] <Vaizki> also smoke is a bad sign
[18:06] <prog> you shouldn't be worried
[18:06] <Vaizki> smoke is very very hard to put back inside such tiny devices
[18:07] <dbrooke> yeah, they get warm, and drift while they're getting there
[18:07] <jet_> So that's why when I started tracking my own payload it drifted for about 10 mins then stayed still...
[18:07] <dbrooke> it's magic smoke

[18:57] <MikkMihkel> Guys... after yesterday's launch when HY1600 bursted prematurely... I would like to purchase new balloon
[18:57] <MikkMihkel> which will carry 2300g payload and would like to achieve maximum altitue
[18:57] <MikkMihkel> What balloon do you recommend?
[18:57] <MikkMihkel> Pawan?
[18:58] <chrisstubbs> Can you reduce the weight? 2300g is pretty hefty!

[22:31] <day> am i seeing this correctly? the nrx2b radiometrix transmitter/receiver has a digital interface? I thought i have to deliver the analog signal that gets modulated onto the carrier freqency. :o
[22:40] Nick change: Crashbone -> Crashbone|Away
[22:42] <day> does that mean the encoding scheme is hard coded into the unit? i simply interact with the unit via a serial bus? I sent 'Hello World' and the transmitter knows how to take care of the RF part?
[22:43] <craag> day: Yep
[22:44] <craag> Feeding in serial directly, without the resistor divider, you'd effectively get *very* wide rtty
[22:45] <craag> Which the NRX2 could then receive and output back as serial
[22:45] <craag> But... at a far shorter range
[22:45] <day> and i thought i have to provide the analog modulation. Take care keying protocols etc o.O
[22:45] <_charlie> Laurenceb: have you seen this paper sent to a bogus publisher? http://www.scs.stanford.edu/~dm/home/papers/remove.pdf
[22:46] <craag> Our uni's paper archive has a lorem-ipsum like tool that generates test papers
[22:47] <craag> Using the msot common words and sentence structure from lots of papers
[22:47] <craag> These have been cited..
[22:51] <_charlie> lol
[22:52] <Laurenceb_> haha
[22:55] <day> craag: i take it the TX2A does not have build in logic? at least i cant see any in the diagrams
[22:55] <craag> day: Not sure what you mean
[22:56] <day> TX2A has an analog input. NRX2B has a digital input with an uC behind it
[22:57] <day> craag: http://imgur.com/kf5zz8K
[22:58] <day> that one looks MUCh harder to use than a module that provides a simple serial interface
[23:00] <day> compared to http://i.imgur.com/jeg6vTD.png
[23:03] <day> hm the tx2a takes digital input levels as well, according to the datasheet. but how on earth can it use them with the shown diagram. Unless the VCO is able to create 2different frequencies depending on the binary input
