[00:00] <jcoxon> i've sent out quite a few emails so hopefully someone will volunteer to help out further south
[00:01] <G8DSU> I emailed a mate in France but he hasn't responded. Outside chance that he has appropriate kit. Also wondered whether to camp in my 10th floor office in Woking but probably not much of an advantage...
[00:01] <jcoxon> natrium42, okay i've worked out how we can make an online radio for you
[00:01] <jcoxon> G8DSU, great on the email, i'd stay comfortable at home :-)
[00:02] <N900evil> broadly speaking. range improves only when altitudes are similar with tolwers added
[00:02] <N900evil> if one is at 10km - well - altitude on the lolw end isn't imporant..
[00:03] <G8DSU> N900evil - yes, and even at that height I'd not see over the Downs a few miles to the south.
[00:04] <N900evil> google earth can wolrk
[00:04] <G8DSU> Bed calls. Talk soon.
[00:04] <jcoxon> if the worsed case occurs i'll drive down to the south coast and track from there
[00:04] <jcoxon> night G8DSU
[00:04] <N900evil> add a poi at your site
[00:05] <N900evil> see what height you can see it from with cam
[00:05] <N900evil> without terrain getting in way
[00:05] <jcoxon> right bed time for me too
[00:05] <jcoxon> night all

[01:37] <juxta> hi all
[01:42] <juxta> rjharrison: are you about?
[01:42] <natrium42> yo juxta
[01:42] <juxta> hey natrium42
[01:42] <juxta> how's things?
[01:42] <natrium42> good, coding some camera stuff
[01:42] <natrium42> you?
[01:43] <juxta> not too bad, trying to design a board
[01:43] <juxta> this is my first crack at using eagle :)
[01:44] <natrium42> ah, let me know if you have any problems
[01:44] <natrium42> i use it quite a lot
[01:45] <juxta> had a hassle where I couldnt see my components before - but I got that sorted, colours etc were not ideally set :)
[01:46] <juxta> natrium42: next launch I'd like to have data logged more frequently - I'm thinking 1hz for GPS, temps, pressure etc - I'm thinking of offloading the RTTY to another uC
[01:47] <natrium42> good idea, i always log as quick as the data comes in (assuming that lat/lon/alt changed)
[01:47] <juxta> yea
[01:47] <juxta> I would do it on the same controller, but then it throws the timing for the RTTY out
[01:48] <natrium42> avr isn't great for multitasking
[01:49] <natrium42> second controller is probably a good idea
[01:49] <juxta> i'll just link them with a serial line, should make things easy
[01:49] <juxta> I need to get an AVR programmer, I'm using chips with the arduino bootloader pre-loaded at the moment
[01:50] <Endeavour> Natrium42.
[01:51] <Endeavour> Greetings.
[01:51] <natrium42> hey Endeavour
[01:51] <natrium42> any news?
[01:51] <Endeavour> Nope.
[01:51] <Endeavour> Just waiting on my 3D Printer.
[01:51] <natrium42> i want one too :S
[01:51] <natrium42> juxta, the best one there is would be avr jtagice mkii
[01:52] <natrium42> i got a cheap clone, not the original one
[01:52] <Endeavour> Got my team to all order some Arduinos and start to learn programming.
[01:52] <natrium42> it's quite expensive if you get it from atmel
[01:52] <juxta> natrium42: where did you get your clone?
[01:52] <natrium42> hm, let me check
[01:52] <juxta> cheers :)
[01:52] <Endeavour> Debating whether or not to do the balloon or not though
[01:53] <juxta> I was looking at the AVR-ISP MKII or the usbtiny one from ladyada
[01:55] <natrium42> hm, can't find it anymore
[01:55] <natrium42> http://cgi.ebay.com/NEW-Emulator-AVR-JTAG-ICE-MKII-USB-mega-w-ISP_W0QQitemZ220551172971QQcmdZViewItemQQptZLH_DefaultDomain_0?hash=item3359dfd36b
[01:55] <natrium42> there's ebay...
[01:58] <juxta> heh, I was hoping to get away under $50 ;p
[01:58] <juxta> natrium42: have you used the lassen IQ?
[01:58] <natrium42> yes, but not on flights
[01:59] <natrium42> it might be a good idea to add a back up battery to it
[01:59] <natrium42> a lithium coin cell
[02:00] <juxta> I'm just looking at Rob's schematic for the Icarus II board - do you know why both GPS RX lines are held high?
[02:00] <natrium42> then it will get lock much faster when you start the payload
[02:00] <SpeedEvil> juxta: is it i2c?
[02:00] <juxta> natrium42: yeah, I had backup battery on it this time, still took its time to get lock :(
[02:00] <natrium42> ah
[02:00] <juxta> SpeedEvil: no, just async serial
[02:00] <natrium42> juxta, the datasheet says to add some resistors
[02:01] <natrium42> not sure on which lines though
[02:01] <juxta> will double check it, cheers natrium42
[02:01] <natrium42> it's quite scary the way they word it
[02:01] <natrium42> something like the module might break if you don't add them...
[02:01] <juxta> haha
[02:06] <juxta> ok, found it natrium42
[02:07] <natrium42> are you still on for this weekend?
[02:10] <juxta> nah, no launch this weekend unfortunatley
[02:11] <juxta> too busy with other things :(
[02:12] <natrium42> kk
[02:13] <juxta> natrium42: do fuse values need to be changed on AVR's to vary the voltage they run at?
[02:45] <natrium42> only for the brown-out detector
[03:08] <juxta> natrium42: that's what I suspected - should be OK I think
[03:08] <juxta> also, running 2 AVR's on the same crystal/caps should be OK, shouldnt it?
[03:09] <N900evil> together?
[03:09] <natrium42> no
[03:09] <N900evil> no, that won't work simply
[03:09] <natrium42> hmm, do avrs have clock output?
[03:10] <natrium42> you can use clock output if you can configure it
[03:10] <N900evil> I mean
[03:10] <SpeedEvil> The crystal oscillator part of the avr has two pins
[03:11] <SpeedEvil> (doh)
[03:11] <SpeedEvil> these are input and output pins
[03:11] <SpeedEvil> you can connect the output pin of one to the input pin of the other.
[03:11] <SpeedEvil> With the crystal connected to the first
[03:11] <SpeedEvil> you probably would need to omit the cap on the pin connected to the other AVR
[03:11] <SpeedEvil> as that will do for that

[07:17] <jcoxon> morning natrium42
[07:17] <jcoxon> i think my emails might finally have got to people

[07:25] <natrium_> jcoxon, i updated the tracker, does it look right?
[07:25] <jcoxon> yeah it looks great
[07:26] Action: natrium_ needs to update the graphics...
[07:27] <natrium_> i want to try drawing a balloon instead of those google markers
[07:27] <natrium_> and the distance between it and its shadow would signify altitude
[07:27] <natrium_> then it would switch to a parachute once descent is detected :P
[07:28] <jcoxon> hehe
[07:29] <juxta> that would be nifty natrium_ :D
[07:32] <jcoxon> could we have a car for car chasers
[07:32] <natrium_> yes
[07:32] <jcoxon> :-p
[07:32] <natrium_> with track that is off by default :P
[07:32] <jcoxon> also perhaps put the listeners on as well
[07:32] <jcoxon> again off by default
[07:33] <natrium_> so, ferrari or lambo?

[07:34] <juxta> trabant's are awesome
[07:34] <natrium_> you have heard of trabant in australia?
[07:34] <juxta> I dont think there's a single one in Australia though somehow
[07:35] <juxta> a friend of mine in Germany has one
[07:35] <natrium_> hehe
[07:35] <natrium_> it's plastic with one powered wheel..
[07:35] <juxta> not plastic as such, it's cotton fibre mixed with a resin, isnt it?
[07:36] <natrium_> the pride of german democratic republic's engineers
[07:38] <natrium_> "The Trabant was a steel monocoque design with roof, bootlid/trunklid, bonnet/hood, bumpers/fenders and doors in Duroplast, a form of plastic containing resin strengthened by wool or cotton. This helped the GDR to avoid expensive steel import"
[07:38] <juxta> ahh, close enough :P
[07:38] <juxta> cotton car
[07:40] <jcoxon> hmmmmm if i get my filling calcs wrong on sat we could be flying over london
[07:40] <juxta> what happens if you fly over london jcoxon?
[07:41] <juxta> is there a way to put components on both sides of a board in the light version of EAGLE?
[07:41] <jcoxon> juxta, nothing much though really try and avoid it
[07:42] <jcoxon> my concern is that we are quite low altitude at this point
[07:42] <jcoxon> however we'll only over fly london (heathrow) if we have a high ascentrate

[07:46] <juxta> ah, that's quite slow
[07:46] <jcoxon> it went quite high :-p
[07:47] <jcoxon> well we need it to float once sunset hits
[07:47] <juxta> I ended up with about 8m/s on my launch the other day, somewhat overfilled my balloon :)

[07:55] Guest2093 (~john@adsl.jcu.me.uk) got netsplit.
[07:55] <juxta> Farnell Australia had it, but it was pretty pricey, around $150
[07:56] <natrium_> wow
[07:56] <natrium_> i think it cost me less than $20
[07:56] <juxta> :O
[07:56] <natrium_> digikey.com
[07:56] <juxta> I'll check it out
[07:56] <juxta> digikey were being assholes about shipping when I wanted something from them
[07:57] <juxta> I wanted a single 12mm coin cell battery holder, they wanted about 30 or 40 dollars for shipping on a 20c item
[07:57] <natrium_> they use express probably
[07:57] <juxta> and they refused to send it in anything besides a big padded box
[07:58] <juxta> you found the sensor pretty accurate, didnt you natrium_?
[08:01] <natrium_> yes, but it started to deviate above a certain altitude
[08:01] <natrium_> just need a profile with the gps data

[09:10] <jcoxon> have been searching for radio listeners

[09:18] <jcoxon> view.php shows that a guernsey amateur radio operator has fired up dl-fldigi
[09:18] <jcoxon> and also wb8elk
[09:18] <russss> heh
[09:20] <MikeMc68> there are two guys I know that might be listening this weekend too
[09:20] <MikeMc68> they live in same area as me in Kent
[09:20] <MikeMc68> One has an AOR-8200 scanner
[09:20] <MikeMc68> no idea what the other guy has
[09:21] <jcoxon> MikeMc68, the more the better
[09:21] <MikeMc68> yeah
[09:23] <ei7ig_laptop> dumb question before I start the build.
[09:23] <ei7ig_laptop> is it using the gui as well? I'm building remotely.
[09:24] <ei7ig_laptop> ah it is..
[09:24] <ei7ig_laptop> I see it in the guide.
[09:24] <ei7ig_laptop> dumb question!
[09:25] <ei7ig_laptop> dumb question no 2... is it going to overwrite my existing fldigi settings or will it just 'use' them?
[09:25] <jcoxon> ei7ig_laptop, now that is a good question
[09:25] <jcoxon> we;ve added a number of fldigi settings
[09:25] <jcoxon> would be worth backuping up your .fldigi
[09:25] <ei7ig_laptop> FYI.. I've an FT-847, Watson 2000 vertical, pre-amp. and I'm far enough away, that I should get it fairly well off the omni

[09:50] <jcoxon> its pretty easy to setup
[09:50] <MikeMc68> guys
[09:50] <edmoore> yo
[09:51] <MikeMc68> someone has built the fl-digi from source code onto his iMac - it is working, but he is trying out the example .wav file and says the stock settings won't work
[09:51] <MikeMc68> can anyone tell me what the settings should be for him to decode it successfully please ?
[09:51] <edmoore> what is the wav file that he has?
[09:51] <MikeMc68> it's an older non-intel iMac btw
[09:53] <juxta> hmm, anyone familiar with the MPX5100 pressure senors? the MPX5100A is an absolute pressure sensor, with a range from 15-115kPa, the MPX5100D is a differential pressure sensor, with a range of 0-100kPa
[09:53] <MikeMc68> edmoore: not sure, let me find out
[09:53] <jcoxon> yeah it really depends on the wav file, and an imac will be challenged by decoding rtty
[09:54] <jcoxon> if its <700mhz it'll drop down to a different method
[09:54] <juxta> the MPX5100D is available with a single 'input' as such, would it have some sort of internal vacuum reference?
[09:55] <MikeMc68> I think he might be using one of these - http://spacenear.us/wiki/doku.php?id=dlistening:client
[09:57] <jcoxon> MikeMc68, the wavs at teh bottom?
[09:57] <jcoxon> those are MFSK
[09:57] <jcoxon> not RTTY
[09:58] <MikeMc68> maybe not then
[09:58] <MikeMc68> i'll find out what he is using
[09:58] <jcoxon> check out http://tenbus.co.uk/icaruscapture_30secs.wav
[09:58] <jcoxon> thats 30seconds of icarus
[09:59] <MikeMc68> thanks i'll let him know
[09:59] <jcoxon> ei7ig_laptop, dl-fldigi is working for you: http://www.robertharrison.org/listen/view.php if you add lat and lon it'll plot you on our listeners map

[10:08] <edmoore> websdr is so cool
[10:09] <jcoxon> oh just made rx extract on by default and also making it report teh version number onto view.php
[10:09] <edmoore> give me a shout when it's available and i'll upgrade and test
[10:10] <jcoxon> edmoore, to tell the truth its probably more hassle
[10:10] <jcoxon> your version is just fine
[10:10] <edmoore> ok, will stick with
[10:10] <jcoxon> thats teh on i'm using
[10:10] <jcoxon> one*
[10:17] <jcoxon> okay ,just emailed the Isle of Wight Radio Soc
[10:19] <jcoxon> rjharrison ping
[10:24] <edmoore> it has just been posted to amsat-bb
[10:25] <jcoxon> yay
[10:25] <jcoxon> hehe
[10:25] <edmoore> so thats a few thousand hams with UHF kit
[10:26] <jcoxon> right just got G8BKE on view.php
[10:26] <jcoxon> who is based near bournemouth
[10:26] <edmoore> perfect
[10:26] <russss> cool
[10:27] <edmoore> the winds are serios for saturday
[10:27] <edmoore> it's heading south like a rocket
[10:27] <jcoxon> yeah
[10:28] <jcoxon> might be an issue once in france
[10:28] <russss> maybe we need some more jambons francais.
[10:30] <jcoxon> edmoore, yeah G3VZV who posted on amsat got in contact last night
[10:30] <edmoore> cool
[10:30] <jcoxon> he is based near milton keynes with az/el antenna
[10:30] <edmoore> do you know if he went to the colloqium?
[10:30] <edmoore> his call vaguely rings a bell
[10:30] <jcoxon> i don't
[10:30] <jcoxon> know
[10:31] <jcoxon> edmoore, oh did i say we've got a france notam as well
[10:31] <edmoore> awesome
[10:32] <jcoxon> now the challenge will be getting the slow ascent rate :-)
[10:33] <rjharrison_> jcoxon pong
[10:33] <jcoxon> we need to think about using UTC for the listener
[10:34] <jcoxon> as dl-fldigi gets local time i think
[10:34] <jcoxon> which might mess things up with people in different time zones
[10:34] <rjharrison_> OK np!
[10:34] <jcoxon> e.g. if you look on view.php WB8ELK is in a diff timezone so doesn't display on the map
[10:34] <rjharrison_> But dl-fldigi doesn't send time!
[10:35] <rjharrison_> Just the payload string?
[10:35] <jcoxon> really?
[10:35] <jcoxon> on the ZZ string?
[10:35] <rjharrison_> Oh that
[10:35] <rjharrison_> I forgot about that
[10:35] <rjharrison_> I'll just ignore and use the server time
[10:37] <jcoxon> pah we can change dl-fldigi as well
[10:37] <jcoxon> timeinfo = localtime ( &rawtime );
[10:37] <jcoxon> strftime(date_time,80,"%Y-%m-%d %H:%M:%S",timeinfo);
[10:37] <jcoxon> localtime to gmtime
[10:40] <rjharrison_> OK but there is sense in taking the time from the server as it prevents inconsistancies and local locks being wrong etc...
[10:40] <rjharrison_> clocks
[10:40] <jcoxon> true
[10:40] <rjharrison_> we could just abandon the date stamp in the ZZ
[10:41] <rjharrison_> and I could start by ignoring it
[10:41] <jcoxon> hmmm i think its still useful
[10:47] <ei7ig_laptop> fldigi seems to be working ok.. btw.. I'm using GPS time on the machine.
[10:48] <jcoxon> the time isn't really important :-)
[10:48] <ei7ig_laptop> ok.
[10:48] <jcoxon> just on our listeners map its used to decided when you were last logging data etc
[10:50] <jcoxon> seems like the flight just got posted on the hyperfr mailing list
[10:50] <jcoxon> which is the french vhf etc one i think
[10:50] <jcoxon> ping edmoore
[10:50] <jcoxon> can you try new version of osx dl-fldigi
[10:50] <jcoxon> http://code.google.com/p/dl-fldigi/downloads/list
[10:51] <edmoore> ta
[11:04] <jcoxon> this is getting exciting :-)
[11:05] <edmoore> you guys should come for brunch at 11 in churchill before heading out into the cold. a heartly churchill brunch used to be the de-facto requirement for hab launches :)
[11:06] <jcoxon> brunch will be full of very hungover people

[11:23] <rjharrison_> jcoxon, yep that old chestnut
[11:23] <juxta> oh nice rjharrison :)
[11:24] <rjharrison_> Icarus III payload is inconstruction but not suitalbe for alt attempt
[11:24] <juxta> has anybody used this module before?

[11:25] <jcoxon> juxta, i've seen the module but hte breakout looks great
[11:26] <jcoxon> thats a really good module now
[11:26] <juxta> yeah - it's so cheap, and is supposed to be very sensitive etc too
[11:26] <rjharrison_> juxta looks great to me
[11:26] <juxta> and there's an eagle lib available for the module tiself
[11:26] <rjharrison_> jcoxon loves his ublox
[11:27] <jcoxon> yeah i miss them - stupid lassen
[11:27] <juxta> why did you switch the lassen jcoxon/
[11:27] <juxta> ?
[11:27] <edmoore> ublox are the best, fo sho
[11:27] <jcoxon> juxta, there aren't many cheap gps modules
[11:27] <jcoxon> and as most ballasthalos end up ditching :-p
[11:28] <juxta> ah
[11:28] <juxta> hehe
[11:28] <jcoxon> also there weren't many standalone ubloxes
[11:28] <juxta> where do you get your lassen's from jcoxon?
[11:28] <jcoxon> but increasingly there are
[11:28] <jcoxon> diamondpoint
[11:29] <jcoxon> they are only 29GBP
[11:29] <juxta> I think I'll order that ublox one - it's the same price as the lassen IQ from sparkfun essentially
[11:29] <juxta> ah that's quite cheap jcoxon
[11:30] <juxta> I have shipping on anything I buy too of course :)
[11:30] <jcoxon> oh yeah, that ublox is massively superior
[11:30] <jcoxon> 50channels verses 12!
[11:31] <juxta> jcoxon: I never understood why 50 channels would be useful - are there even 50 GPS sats orbiting?
[11:31] <jcoxon> no there aren't :-)
[11:32] <juxta> didnt think so ;p
[11:32] <jcoxon> but it allows for more monitoring of signals
[11:33] <juxta> fair enough
[11:33] <russss> I don't even understand what a "channel" comprises in GPS, don't they all transmit on the same frequency?
[11:33] <juxta> yeah they do russss, but they use TDMA
[11:35] <russss> GPS is deep magic

[11:52] <edmoore> junderwood: it's CDMA, not TDMA

[11:55] <edmoore> oh sorry, my autocompletion failed
[11:55] <edmoore> too many ju*s

[11:56] <edmoore> russss: in our amsat talk, the basics of gps are explained
[11:56] <edmoore> the video is online somewhere
[11:57] <MikeMc68> here is what this guy says about his version of fl-digi with the sample wav.....
[11:57] <MikeMc68> 1) The selected spectrum window on the waterfall. I can't get mine to cover the tramlines properly. Best I can do is stretch it over about two thirds of the required width, which means it probably either sees the ones or the zeros but not both. There must be a setting to change the window width, but I've not found it yet.
[11:57] <MikeMc68> 2) Actually decoding the data. Now, sorting the first may magically sort this, but I'm guessing that somewhere the software needs to be told how many bits per character and what parity, data rate, and so on to expect. Again, not convinced I've found the correct setting.
[11:58] <edmoore> 1) Op Mode > RTTY > custom > Carrier shift
[11:59] <edmoore> 2) Op Mode > RTTY > custom > all of the other settings that define each of what you listed
[12:01] <MikeMc68> are the settings listed anywhere?
[12:02] <edmoore> well infact, configure > operator > DL Client (tab) then selecting icarus should set it all automagically

[13:15] <junderwood> Idea for listener / tracker improvement: How about modifiying the tracker to accept reception frequency from listeners in addition to their position. Then it should be possibly to set up completely autonomous listeners.
[13:16] <junderwood> i.e. grab the current frequency and position, tune and point. No human required to fiddle the tuning dial
[13:35] rjmunro (~chatzilla@ joined #highaltitude.
[13:54] <rjharrison_> That is easier said that done. We have had mixed results in getting the computer to control the rig from fldigi
[13:59] <edmoore> i also wonder about variations between radios being larger than the fidelity required to accurately get the matched-filter cross-hairs on the target
[13:59] <edmoore> i guess it just has to gwet close enough that fldigi can do the rest
[14:10] <junderwood> fldigi seems to control my rig OK using hamlib but I guess others' experiences may differ.
[14:10] <junderwood> Not sure about the variations between radios but I guess they are much smaller than the drift in frequencies during a flight
[14:11] <junderwood> And radio to radio variation can probably be calibrated out.
[14:11] <junderwood> (I guess it's constant within a small frequency range)

[18:23] <jcoxon> hey natrium42
[18:24] <jcoxon> hey LazyLeopard
[18:24] <natrium42> hi james
[18:24] <jcoxon> natrium42, you any good at php?
[18:24] <natrium42> i am ok, what's up?
[18:25] <jcoxon> need to make an interface for the radio
[18:25] <natrium42> ok, do you have some webserver running?
[18:25] <MikeMc68> hi LazyLeopard
[18:25] <jcoxon> will do tomorrow evening
[18:26] <LazyLeopard> Hiya
[18:26] <jcoxon> basically i plan to make an interface for the radio (freq up, down, radio on, off
[18:26] <jcoxon> )
[18:27] <jcoxon> and then using xml-rpc intergrate something with dl-fldigi
[18:27] <jcoxon> so you can shift the decode bars up and down
[18:27] <jcoxon> then have some form of screenshotting of the waterfall for more info
[18:27] <jcoxon> and finally rig streaming of the audio as well
[18:27] <natrium42> ah
[18:28] <natrium42> so you want a php for the "gui"?
[18:29] <natrium42> xml-rpc can be done through javascript
[18:29] <DanielRichman> if the server's running at home, jcoxon, wouldn't it just be more simple to open another port, have whatever piece of C programming you have connected to the radio open a socket... and have dl-fldigi connect to that and send single byte commands?
[18:29] <DanielRichman> stage two: Ethernet for arduino
[18:30] <jcoxon> okay well the radio will be controlled via an arduino
[18:31] <jcoxon> we could open the xml-rpc socket to the world
[18:31] <jcoxon> from dl-fldigi
[18:31] <DanielRichman> no need. If controlled by an arduino... that arduino will be connected via serial to your server pc...
[18:32] <DanielRichman> you just need to connect the arduino's serial connection to the internet; open a port
[18:32] <DanielRichman> a quick C daemon will do the trick (OR... you could write it using netcat and bash?)
[18:32] <DanielRichman> if you want authentication you could do that
[18:32] <DanielRichman> Then fldigi connects to that port, sends byte commands; no xml required
[18:33] <jcoxon> DanielRichman, a php page with a few commands would be pretty easy though
[18:33] <natrium42> could also run a webserver and the scripts (php?) can call the tool to control arduino
[18:33] <DanielRichman> What's the fldigi connection for then?
[18:33] <DanielRichman> Have Fldigi auto-adjust the frequency?
[18:34] <jcoxon> DanielRichman, it has quite a limited afc
[18:34] <DanielRichman> natrium42, yeah, I guess that's how you could connect it anyway since php can open sockets itself
[18:34] <DanielRichman> netcat -l -p 81 > /dev/ttyUSB0
[18:34] <DanielRichman> would do the trick though (to a limited,one-client,proof of concept extent)
[18:34] <natrium42> :D
[18:35] <rjharrison_> wow i'm out of my depth here
[18:35] <rjharrison_> James just way what you want and let them knock somehting up
[18:35] <rjharrison_> just say
[18:36] <jcoxon> okay well i'm going to say that there will be 4 commands available
[18:36] <jcoxon> freq up, freq down, radio on and radio off
[18:36] <rjharrison_> jcoxon how about vnc into your machine
[18:36] <rjharrison_> I'm going to be about
[18:36] <rjharrison_> Rig control?
[18:36] <jcoxon> will have to use dead reckoning
[18:36] <DanielRichman> vnc with a password :X
[18:37] <rjharrison_> Sol long as the I can control your rig I'm sure we have done this before

[20:25] <SpeedEvil> IOr what?
[20:25] <jcoxon> yeah

[21:25] <jcoxon> its unfortunately preset

[21:26] <jcoxon> you'd need to chat to members of CUSF - they prob won't change it though
[21:26] <jcoxon> as we use it to find good days to launch
[21:26] <Lunar_Lander> yeah

[21:30] <Lunar_Lander> and they were like standing there and the balloon came down within sight
[21:32] <MikeMc68> James - I was thinking the other day - of making a simulator for pumping artificial data into the controller board
[21:33] <MikeMc68> like take the current weather and wind conditions and then pump altitude and location data (like a GHPS string) into the microcontroller so you can test kit almost as if it were for real
[21:33] <jcoxon> yeah that would be amazing
[21:33] <jcoxon> we have fake gps generator from kml already
[21:33] <jcoxon> but it would be nice to make a loop
[21:33] <MikeMc68> but I mean real live weather conditions

[23:01] <jcoxon> evening Laurenceb and edmoore
[23:01] <Laurenceb> its true and it rhymes
[23:02] <natrium42> it's true because it rhymes
[23:02] <rjharrison> ping jcoxon
[23:02] <jcoxon> rjharrison, yes
[23:02] <rjharrison> You may like this james http://www.robertharrison.org/listen/view.php?reg=/M6JCX%20:%20ATLAS/
[23:02] <rjharrison> ah well the %20 is a space
[23:03] <SpeedEvil> http://resources.zdnet.co.uk/articles/0,1000001991,40022669,00.htm - chip and pin broken. In cambridge too.
[23:03] <jcoxon> it works
[23:03] <natrium42> rjharrison, is it possible to grab stats on the listeners somehow?
[23:03] <rjharrison> but basically its a reg expression
[23:03] <rjharrison> natrium42 sure what stats do you want
[23:03] <rjharrison> ie who is listenin etc?
[23:03] <natrium42> hmm, actually, is it possible to get which listeners received a position?
[23:04] <natrium42> then i could draw animated wavy lines once a position comes in
[23:04] <natrium42> around the station
[23:04] <natrium42> or stations
[23:05] <rjharrison> Humm, Yep if you know the positions lat,lng and alt then I guess I can give you a list of the loggers callsigns
[23:05] <rjharrison> Shall I do that
[23:05] <rjharrison> How would you like the results
[23:05] <natrium42> is it possible to send a list of receivers with each position?
[23:06] <natrium42> or do you only get it later?
[23:06] blomlet (~quassel@cpc4-dals16-2-0-cust522.hari.cable.virginmedia.com) joined #highaltitude.
[23:06] <rjharrison> Well I post the position to you as soon as I get it. So from the first logger
[23:06] <rjharrison> the other data is posted to you too but you drop identical lat,long,alt
[23:07] <rjharrison> I can add the initial logger to the upload if you like
[23:07] <natrium42> ok, can you post the ID and the receiver then, it's fine if there are duplicate IDs (but different receivers)
[23:08] <rjharrison> Ok whats the current format for that
[23:08] <natrium42> there is none, just add the fields and name them at your discretion :)
[23:09] RocketBoy (~Steve@ left irc: Read error: Connection reset by peer
[23:09] <natrium42> then i will add them in
[23:09] <Laurenceb> SpeedEvil: your suggestion for aluminium as a anemometer fin - its only 16% worse than copper
[23:10] <SpeedEvil> speed of heat?
[23:10] <SpeedEvil> or what metric - I forgot
[23:10] <Laurenceb> so not too bad, but silver is 50% better
[23:10] <Laurenceb> conductivity/heat capacity
[23:11] <SpeedEvil> ah
[23:11] <SpeedEvil> diamond!
[23:11] <natrium42> i will also add "horizon"
[23:11] <natrium42> i.e. circle where there is LOS to the payload
[23:11] <SpeedEvil> SRTM?
[23:11] <edmoore> natrium42: that would be super useful
[23:12] <SpeedEvil> http://www2.jpl.nasa.gov/srtm/
[23:12] <edmoore> geometric horizon and perhaps radio horizon too?
[23:12] <Laurenceb> SpeedEvil: its very easy to get 20Hz or so bandwidth for the sensor
[23:12] <SpeedEvil> though that would be lots more complex
[23:12] <SpeedEvil> Laurenceb: that's surprisingly good
[23:12] <Laurenceb> yeah, as good as the pressure sensors
[23:12] <SpeedEvil> Laurenceb: what sort of noise figure?
[23:12] <natrium42> edmoore, hmm, how do i calculate radio horizon?
[23:12] <Laurenceb> dunno - have to build it
[23:13] <Laurenceb> as long as you have laminar flow...
[23:13] <SpeedEvil> http://en.wikipedia.org/wiki/Fresnel_zone natrium42
[23:13] <Laurenceb> and the currents and voltages involved are sensible, so it should give a clean signal
[23:13] <rjharrison> http://spacenear.us/tracker/track.php?vehicle=atlas&time=231244&lat=51.3920&lon=0.5290&alt=-46&heading=&speed=&data=0.0;0;0;25;26;23;43;500;0&pass=XXXX
[23:13] <Laurenceb> need to order that vishay pt100 sensor from farnell and try it
[23:13] <rjharrison> natrium42 this is what I send at the moment
[23:14] <natrium42> SpeedEvil, formula plz :D
[23:14] <rjharrison> will add &callsign=M6JCX
[23:14] <natrium42> rjharrison, ok, add &id=<id>&receiver=<receiver> or something similar
[23:14] <natrium42> yah, that will do
[23:15] <natrium42> could you send the position ids too?
[23:15] <SpeedEvil> natrium42: Ah - the base formulae is there - but you would need to add the curvature of hte earth
[23:15] <rjharrison> I don't know those do I
[23:15] <rjharrison> They get set when you do the insert
[23:15] <rjharrison> or am I missing something
[23:15] <natrium42> oh, i thought that the radio string contained an ID
[23:16] <rjharrison> Oh the sequence
[23:16] <natrium42> yeah
[23:16] <rjharrison> sure
[23:16] <Laurenceb> id suggest just the visual line of sight
[23:16] <Laurenceb> not that hard to calc from lla of each point
[23:16] <Laurenceb> i.e. istener and balloon
[23:17] <SpeedEvil> yeah
[23:17] <SpeedEvil> true
[23:17] <SpeedEvil> SRTM is probably overkill - but would be nice
[23:22] junderwood_ (~John@adsl.jcu.me.uk) got netsplit.
[23:22] Guest2093 (~john@adsl.jcu.me.uk) got netsplit.
[23:23] <rjharrison> natrium42 hum there is a slight problem I only send updates to spacenear.us if they are new points so duplicate lat lng alt are not sent
[23:24] <rjharrison> If you like i can send you a sentance with the sequence and callsign for every clen packet
[23:24] <natrium42> yeah, but i will add code to handle that
[23:24] <rjharrison> clean
[23:25] <rjharrison> Ok so send every sentance to you even duplicate ones
[23:25] <natrium42> hmm, i would rather have the sentences handled on your side
[23:25] <natrium42> then you can adjust format easily
[23:25] <rjharrison> I just set a unique key on table positions;
[23:25] Guest2093 (~john@adsl.jcu.me.uk) returned to #highaltitude.
[23:26] <rjharrison> natrium42 I post the data as above just for every position and not just new ones

[23:27] <rjharrison> like that
[23:28] <rjharrison> NB the callsigns
[23:29] <rjharrison> I can do this quite simply and you will have to parse the callsigns and not plot both positions, but like a say a unique index will prevent that
[23:29] <jcoxon> haha edmoore
[23:30] <rjharrison> jcoxon did i miss something
