[06:59] <daveake> I'm not!
[06:59] <Upu> bit of a headache tbh )
[06:59] <Upu> :)
[06:59] <Upu> didn't drink enough yeterday
[06:59] <daveake> true
[07:00] <Upu> I don't think 2 sips of hot tea are enough to sustain an adult for 6 hours
[07:00] <Upu> might be wrong
[07:00] <daveake> I suspect you're right
[07:00] <daveake> We had drinks in our car :)
[07:01] <Upu> so good planning :)
[07:02] <Upu> mind if I use one of the Buzz pictures for the QSL cards ?
[07:02] <daveake> np
[07:02] <Upu> cheers
[07:02] <Upu> will have a look at that today
[07:02] <daveake> Send me your stuff sometime
[07:02] <Upu> good job it didn't float ...
[07:03] <daveake> Copy to one of those cards before you send them back :)
[07:03] <Upu> trying to work out how we got that prediction wrong
[07:03] <Upu> it was coming away from London later on
[07:03] <Upu> thats gone straight towards it
[07:03] <daveake> Yeah, I don't have the predictions up on my PC now but reality <> those
[07:04] <Upu> I wouldn't have launched if that was the predicition
[07:04] <daveake> It didn't go much higher and went up faster than the ones I ran
[07:04] <daveake> nope
[07:05] <Upu> look where Buzz went an hour and half ealier before it went off line

[07:26] <daveake> The chase cars didn't quite get photographed by the payload on the way down
[07:26] <number10> not far off I bet, looking at spacenear
[07:26] <daveake> We were within 300m when it landed
[07:27] <daveake> And we watched it come in just before
[07:27] <number10> great. did Upu turn on the streaming at the recovery site
[07:27] <daveake> He did
[07:28] <number10> ah thought as much - I must have been just to late when I looked it it as all I saw was Upu http://imgur.com/HLxUm
[07:29] <daveake> Note power lines behind him :p
[07:29] <number10> yes, I spoted them on google maps when you landed, just south of the tree
[07:29] <daveake> Yep. Saved by the trees :)
[07:29] <number10> close shave
[07:30] <number10> yes, I bet you would never have thoght you'd say that

[07:30] <daveake> lol
[07:30] <daveake> Going thru the log from the launch is always a special time :)

[07:41] <number10> I put a second antenna up to track bot - I put some radials on magmount didnt work too good
[07:42] <number10> and the netbook kept disconnecting from wireless lan so lots of frames didnt upload :(
[07:42] <Upu> thats one of (the many) amazing things that happened yesterday the 3G signal didn't disconnect once
[07:45] <number10> sentences upload from mee - Buzz 268, AVA 283, Cloud 85 and blunt162
[07:45] <number10> -e
[07:45] <Upu> lol
[07:45] <daveake> lol

[07:48] <daveake> haha :)
[07:48] <number10> :)
[07:49] <Upu> well there is a bit of disparity given Ava was 6 meters further up the wire than Cloud :)
[07:49] <daveake> Well it's either because the sentences aren't synced, or just the usual GPS noise
[07:50] <Upu> I suspect you got the last sentence before it popped

[08:02] <Morseman> Any launches planed for today?
[08:04] <Upu> not sure been out of the loop for 24 hours :)
[08:04] <Upu> Dave did you get the time lapse video done ?
[08:04] <Upu> and/or looked at it ?
[08:04] <daveake> Not yet. Stopped before the launch, but should be interesting
[08:05] <Upu> be interested in that
[08:05] <daveake> Didn't put fresh batteries in that one :p
[08:05] <Upu> ah :)
[08:05] <daveake> Just copying everything from my netbook then I'll start putting stuff online

[08:08] <Morseman> balsa wood?

[08:11] <daveake> That was a 2-year-old 1600 Hwoyee. The "other Buzz" burst much much lower, and that had a recent one.
[08:11] <Upu> wish we'd used the old one for the pico
[08:11] <Upu> I spoke to Steve on the way home btw
[08:12] <daveake> oh....?
[08:12] <Upu> just explained what had happened
[08:12] <Upu> no real conclusions it is a little odd
[08:13] <daveake> it is
[08:13] <daveake> But that is 3 in a row that have done that
[08:13] <Darkside> navrac: about?
[08:13] <Upu> reminds me I'll do the data
[08:14] <Upu> Buzz payload weight ?
[08:14] <Upu> 65g ?
[08:14] <daveake> Including chute, yes
[08:14] <Upu> neck lift ?
[08:14] <daveake> 1.2kg IIRC
[08:15] <daveake> Yes 1.2 I'm pretty sure
[08:15] <Upu> ava cloud 1.5kg neck lift was? 3.2 ?

[12:44] <r2x0t> then it's diode and filter for 30MHz harmonic
[12:44] <Darkside> or see if the Si4432 can run off 10MHz anyway
[12:45] <r2x0t> I think it always needs 30MHz, then it can output some other clocks

[12:53] <navrac> what confuses me is that the crystal is thermally seperate from the si4432 - so the drifting must be happening in the chip
[12:53] <navrac> and not the xtal
[12:53] <navrac> so it can only be the internal programmable chip capacitance that can be drifting

[13:42] <Matt_soton> TCXOs arnt that cheap mind you
[13:42] <Matt_soton> well not from farnell
[13:42] <Laurenceb_> shrug
[13:43] <Laurenceb_> ~£3 or so ive got them for
[13:43] <jonsowman> i was looking for a 13.58M tcxo
[13:43] <Laurenceb_> try RS
[13:43] <Matt_soton> jonsowman: you cant find a 13.58 XO let alone TCXO
[13:43] <jonsowman> indeed
[13:43] <jonsowman> :(
[13:43] <Matt_soton> unless you get a fancy integrated PLL thing
[13:43] <Matt_soton> that is TC

[13:44] <Matt_soton> although i cant help but think youre trying to create a simple low cost thing, and using a fancy pll wont help
[13:45] <jonsowman> exactly
[13:45] <jonsowman> i think getting a 13.58M xo and then manually temperature compensating it is the way to do
[13:45] <Matt_soton> tahts what i intend to do
[13:46] <Laurenceb_> cant it take a 30m TCXO?
[13:46] <Laurenceb_> 30MHz
[13:46] <Matt_soton> also use a 10ppm XL

[13:49] <Upu> err didn't pay for it :)
[13:49] <Laurenceb_> ah, nice and simple
[13:49] <jonsowman> okay, was just wondering how much they are
[13:49] <Matt_soton> jonsowman: you should have fed the 13.56MHz crystal into the AVR
[13:49] <jonsowman> Laurenceb_: that's the idea
[13:49] <Matt_soton> saved yourself a crystal
[13:50] <Laurenceb_> rather like on board radiometrix
[13:50] <jonsowman> Laurenceb_: exactly that
[13:50] <Laurenceb_> can it do rx?
[13:50] <jonsowman> Matt_soton: then timing on the avr would have been a pain

[13:52] <jonsowman> i suppose
[13:52] <Matt_soton> do we really need uplink?
[13:52] <Matt_soton> i was looking at the max7032
[13:52] <jonsowman> well depends what you want
[13:52] <jonsowman> joey was designed as a super simple tracker really

[13:55] <Laurenceb_> Matt_soton: nice find
[13:55] <Matt_soton> surely farnell must do 10.7MHz ceramic filters though ://
[13:58] <Laurenceb_> Matt_soton: hmm im thinking grab the IF with an stm32
[13:58] <Matt_soton> mind you uplink is easy, you dont tend to need a high bandwidth and you can blast it with alot of power
[13:59] <Matt_soton> so i would just use its ASK demod
[14:01] <Laurenceb_> hmm you cant lower th eif much
[14:01] <Laurenceb_> *the IF
[14:01] <Laurenceb_> or it suffers from poor image reject
[14:01] <Laurenceb_> thats a pity
[14:01] <Matt_soton> oh
[14:02] <Matt_soton> just use its demod tbh
[14:02] <Laurenceb_> 48dB @ 10mhz
[14:02] <Laurenceb_> i was thinking lower the if and grab with stm32
[14:03] <Matt_soton> this still for balloon uplink or a general reciever?
[14:03] <Laurenceb_> both
[14:03] <Matt_soton> makes more sense to try to sample the IF for a general reciever, but then might as well try to get some elonics parts
[14:03] <Laurenceb_> cc1020 still looks best for that

[18:53] <Matt_soton> do you have flux?
[18:53] <navrac_> qhaes the issue?
[18:53] <navrac_> what is
[18:59] <navrac_> on small parts if i havent got a fine iron i pre tin the pads, then clean the iron and then use the heat the pad and pin at the same time - needs plenty of flux tho
[19:00] <Matt_soton> i tend to put a bit of solder on the edge of the iron (even large irons have some sort of edge) and then touch that on the point
[19:00] <Matt_soton> needs flux on the joint mind you
[19:01] <Matt_soton> the other method is to make a mess and use solder braid afterwards
[19:01] <cuddykid> I've made a complete mess and solder braid isn't really helping :/

[19:50] <Elmar_PD3EM> OZ1SKY_Brian: good luck
[19:50] <Morseman> fsphil-laptop just bluetooth between the radio and the phone...
[19:50] <OZ1SKY_Brian> i hope to collect alot of easteregs, lol
[19:50] <fsphil-laptop> that would indeed be quite neat
[19:51] <fsphil-laptop> it would be trivial for a manufacturer to put a small arm processor in a radio these days
[19:51] <Elmar_PD3EM> Upu, do you have pressure data from the Buzz flight with GPS altitude?
[19:51] <fsphil-laptop> even the older ones would be powerful enough
[19:52] <Randomskk> I'm hoping icom/yaesu will up the ante a bit with the next gen mobile radios
[19:52] <Upu> Good question Elmar, daveake should have the answer
[19:52] <Randomskk> there's no reason they shouldn't have really decent screens and processors and tbh good SDR
[19:52] <Upu> but the raw data is here : http://www.robertharrison.org/listen/view.php
[19:52] <fsphil-laptop> Randomskk, yea. or someone else could come in and steal their market :)
[19:52] <Randomskk> fsphil-laptop: wouldn't surprise me if they don't do something about it
[19:53] <Elmar_PD3EM> I'll try to parse that for Buzz data ;-)
[19:53] <fsphil-laptop> they've no reason to Randomskk
[19:53] <Randomskk> Upu: that link only shows data from people with old versions of dl-fldigi, by the way
[19:53] <fsphil-laptop> people are still buying their radios
[19:53] <Randomskk> Elmar_PD3EM: hang on a second
[19:53] <fsphil-laptop> I wonder how difficult it would be to put together an open source rig
[19:53] <Elmar_PD3EM> I'll wait Randomskk ;-)
[19:53] <fsphil-laptop> powered by an SDR
[19:53] <Upu> what is considered latest ?
[19:53] <Randomskk> Elmar_PD3EM: all the buzz data, parsed: http://habitat.habhub.org/habitat/_design/habitat/_view/payload_telemetry?startkey=[%22BUZZ%22,0]&endkey=[%22BUZZ%22,%22end%22]&include_docs=true
[19:53] <Randomskk> in JSON format
[19:53] <Randomskk> you should be able to grab that in python or php or perl or ruby or whatever you like using
[19:53] <fsphil-laptop> the latest proper release is still the old version
[19:53] <Elmar_PD3EM> Randomskk: thanks!
[19:54] <Randomskk> fsphil-laptop: true
[19:54] <fsphil-laptop> but the new one is working well
[19:54] <fsphil-laptop> I think it could be released anytime now
[19:54] <Randomskk> well
[19:54] <Randomskk> yea
[19:54] <Randomskk> soon
[19:54] <fsphil-laptop> although I'd like to test it for memory leaks
[19:54] <fsphil-laptop> Morseman sees it slowing and crashing eventually
[19:54] <Upu> fine send it on I'll test it
[19:54] <Randomskk> we plan to be transitioning the database structure to one suitable for release and well documented
[19:54] <fsphil-laptop> ah
[19:54] <Randomskk> so that'l be a few hours where we shut it all down to swap over
[19:54] <Upu> I'm running Dl-Fldigi-3.21.13
[19:55] <Randomskk> and once swapped, we can release a dl-fldigi
[19:55] <Randomskk> and the rest
[19:55] <Upu> ok
[19:55] <fsphil-laptop> can we get rid of the \n dependency :)
[19:55] <Randomskk> yea that's an issue we'll sort out
[19:55] <fsphil-laptop> my solution is a bit hacky
[19:55] <Randomskk> well
[19:55] <Randomskk> it is a bit, but
[19:55] <Randomskk> it's hard to say what's best. ideally people should be consistent with termination
[19:55] <Randomskk> rather than some people using \r\n and some people using just \n
[19:56] <fsphil-laptop> both are valid for rtty though
[19:56] <Randomskk> well "valid"
[19:56] <Randomskk> rtty doesn't say either
[19:56] <Randomskk> both are just data
[19:56] <fsphil-laptop> true
[19:56] <Randomskk> so is using / instead of , to separate fields
[19:56] <fsphil-laptop> valid in that fldigi and the other decoders handle it
[19:56] <Randomskk> but for "UKHAS" telemetry we could say one is valid
[19:56] <Randomskk> and then do what we already do if people transmit invalid telem
[19:56] <Randomskk> use a filter to change the raw data
[19:56] <Randomskk> which would work
[19:56] <Matt_soton> fldigi should take 4 characters after * as End of line
[19:56] nosebleedkt (~nosebleed@79.167.97.61) left irc: Quit: If you run, you only gonna die tired
[19:56] <Randomskk> Matt_soton: some checksums are two digits
[19:57] <eroomde> i would quite like a manual interface to upload strings
[19:57] <eroomde> if poss
[19:57] <eroomde> quite often you'll get a string which you're pretty sure is good but for a missing $
[19:57] <eroomde> or something
[19:57] <Elmar_PD3EM> I was looking at this module: http://www.parallax.com/tabid/768/ProductID/780/Default.aspx (Pressure range of 101200 mbar)
[19:57] <Randomskk> eroomde: that basically already exists iirc, http://habitat.habhub.org/transition/ but needs a bit of work
[19:57] <Matt_soton> Randomskk: well fidigi knows whether it should be 2 or 4
[19:57] <Randomskk> eroomde: but yea, that's also coming fairly soon
[19:57] <Randomskk> Matt_soton: no it doesn't
[19:57] <eroomde> cool
[19:57] <Randomskk> Matt_soton: also some payloads lack checksums
[19:57] <Randomskk> I think having an end of line terminator is reasonable enough
[19:57] <Matt_soton> well it can use both methods :P
[19:57] <fsphil-laptop> we should ignore and shun those without checksums
[19:57] <Randomskk> though there are discussions about not having it be part of the spec
[19:58] Zuph (~Zuph@69.64.6.70) left irc: Ping timeout: 246 seconds
[19:58] <Randomskk> fsphil-laptop: I don't disagree. the point is mostly that we can't rely on checksum length as the end of the sentence
[19:59] <Matt_soton> doesnt fldigi know what type of checksum though?
[19:59] <fsphil-laptop> I still think not requiring the $$ and \n is best -- use them to detect where the string is, but discard them after that
[19:59] <Randomskk> eroomde: but that form is pretty messy. there'l be a better one which also functions as a kind of parser-debug, i.e. it'l show you what the parse errors are / why it's not working
[19:59] <Randomskk> Matt_soton: only if you've autoconfigured for a payload, which is optional
[19:59] <Randomskk> fsphil-laptop: yea that's one option that's on the boards
[19:59] <Matt_soton> does it upload anythinng if you dont then?
[19:59] <Randomskk> Matt_soton: it uploads $$ to \n
[19:59] <Matt_soton> oh ok
[20:00] <Randomskk> from the text output
[20:00] <Randomskk> but autoconf is used to help it parse the data for display in hab mode

[20:37] <Elmar_PD3EM> even down to 1441 (14 hPa) at 27.6 km altitude. Thought it wouldn't go below its specs....
[20:38] <Randomskk> the spec is just what they promise it'l work at and be within specified accuracy at
[20:38] <Randomskk> once you're out of spec there's no promise it's at all accurate or how far it'l go, or that different units will manage the same
