[00:00] <Lunar_Lander> NigeyS I just checked the datasheet for my DS1821 temp sensor
[00:00] <Lunar_Lander> it has three legs

[00:00] Dan-K2VOL (~Adium@69.64.6.70) joined #highaltitude.
[00:00] <Lunar_Lander> GND, VCC and DQ
[00:00] <Lunar_Lander> so I think, DQ goes into any data port?
[00:01] <jcoxon> Dan-K2VOL, you going for simulation this evening?

[00:03] <Lunar_Lander> hm
[00:03] <Lunar_Lander> 1-Wire
[00:03] <Lunar_Lander> writing 1 and writing 0
[00:03] <Lunar_Lander> that's digital, right?
[00:06] Dan-K2VOL (~Adium@69.64.6.70) left irc: Quit: Leaving.
[00:09] <Lunar_Lander> ?
[00:10] <Lunar_Lander> well it is called "Programmable Digital Thermostat and Thermometer"
[00:11] <SpeedEvil> you need a port that can do input and output
[00:11] <SpeedEvil> but, yes.
[00:11] <Lunar_Lander> ah
[00:16] <Lunar_Lander> hm
[00:16] <Lunar_Lander> you can operate it with data and ground
[00:16] <Lunar_Lander> or data, ground and supply voltage
[00:16] <jcoxon> i recommend with supply voltage
[00:16] <jcoxon> its more reliable
[00:16] <Lunar_Lander> yeah I would have thought so
[00:16] <Lunar_Lander> so, that one goes to the 5V
[00:16] <Lunar_Lander> or wait
[00:17] <Lunar_Lander> datasheet says "0.7 to 5.5V"
[00:17] <jcoxon> there is a nice diagram in the datasheet iirc
[00:18] <Lunar_Lander> ah I think I found it
[00:18] WhiteStarMC-173_ (~WhiteStar@69.64.6.69) left irc: Ping timeout: 240 seconds
[00:18] <Lunar_Lander> the DQ goes to the RX of the ┬ÁC
[00:19] <jcoxon> so on the arduino the 1-wire library is software based
[00:19] <Lunar_Lander> ah
[00:19] <jcoxon> so you can set it up to work on any of the output pins
[00:20] <Lunar_Lander> http://milesburton.com/index.php?title=Dallas_Temperature_Control_Library
[00:20] <Lunar_Lander> like that library?
[00:20] <jcoxon> imrcly, ping
[00:21] <jcoxon> Lunar_Lander, http://www.arduino.cc/playground/Learning/OneWire
[00:21] <Lunar_Lander> I have just found that one also
[00:23] <Lunar_Lander> btw
[00:23] <Lunar_Lander> I got the DS1821 and also two DS1821S
[00:23] <Lunar_Lander> according to the datasheet, the pins on the DS1821S are the same, VDD, DQ and GND
[00:23] <Lunar_Lander> and the other five pins are NC

[00:37] <dehuman> 4.7k
[00:37] <Lunar_Lander> yeah I saw it on the sheet
[00:38] <dehuman> i love those little sensors, i have a bunch of ds10s20 or whichever one is 12 bit
[00:38] <dehuman> crazy resolution

[00:43] Nick change: grummund_ -> grummund
[00:44] <Zuph> So he is!
[00:44] <natrium42> it's late in UK
[00:44] <natrium42> :)
[00:44] <Zuph> Yes, and evidently, I'm keeping him up :)
[00:44] <Lunar_Lander> and later in germany
[00:44] <Lunar_Lander> xD
[00:44] <natrium42> yeah, but you're a nightowl
[00:45] <Lunar_Lander> me?
[00:45] <natrium42> no?
[00:45] <Lunar_Lander> xD you are absolutely right
[00:45] <Lunar_Lander> :)
[00:45] <NigeyS> i've never fully readjusted from working nights :/
[00:46] <Lunar_Lander> is this good? http://cgi.ebay.de/Profi-Lotstation-Lotkolben-58-Watt-450-Spitzen-Set-/350201558537?pt=DE_Haus_Garten_Heimwerker_Elektrowerkzeuge&hash=item5189a3b609
[00:46] <Zuph> This balloon project is killing me. I'm ordinarily a morning person
[00:46] <NigeyS> lol Zuph .. when its over you can sleep for a week!
[00:46] <Zuph> Here's hoping!
[00:46] <Zuph> Lunar_Lander: We have a bunch of those at the hackerspace
[00:46] <Lunar_Lander> ah
[00:46] <Zuph> Albeit with more English
[00:46] <Zuph> They don't suck, but they aren't great.
[00:47] <Lunar_Lander> yeah :D
[00:47] <Zuph> For 20 eur, they're very decent.
[00:47] <Lunar_Lander> this: http://cgi.ebay.de/Digitale-Lotstation-150-450-C-Lotkolben-48W-d2958-/130479236176?pt=DE_Haus_Garten_Heimwerker_Elektrowerkzeuge&hash=item1e612b2450 ?
[00:47] <Zuph> For 50-75 eur you can get something much better, though.
[00:48] <Lunar_Lander> yea

[00:50] <NigeyS> cat nap?
[00:50] <jcoxon> left it on so that dan could contact me
[00:51] <natrium42> aah
[00:51] <jcoxon> Dan-K2VOL, you need to flush your old data before i can run the script for the sat data
[00:51] <Lunar_Lander> Zuph did you see my 2nd link?
[00:51] Action: natrium42 uses irssi on a server
[00:51] <Zuph> jcoxon: I'm on it
[00:52] <Zuph> jcoxon: actually, how do i do that? :-p
[00:53] <Zuph> Lunar_Lander: Yeah, that one looks nicer, but they don't have enough pics to judge real well
[00:54] <Lunar_Lander> ah
[00:54] <Zuph> jcoxon: Oh, for our satellite data
[00:54] <Zuph> jcoxon: gotcha, working on it.
[00:55] <jcoxon> oh year i mean you database
[00:55] <jcoxon> yeah*
[00:57] <natrium42> jcoxon: what's the callsign for whitestar?
[00:57] <jcoxon> wb8elk2
[00:57] <natrium42> satellite too?
[00:58] <jcoxon> yup
[00:58] <natrium42> ok, adding special case :)
[00:58] <jcoxon> to spacenear.us it won't see a difference
[00:58] <jcoxon> apart from the custom field being larger for the sat data
[01:01] <jcoxon> Zuph, any success?

[01:02] <jcoxon> hehe sorry
[01:03] <Dan-K2VOL> Daatabase guy is just now telling us how to accomplish that
[01:03] <Dan-K2VOL> Np
[01:03] <jcoxon> will stop pestering
[01:03] <Dan-K2VOL> I know it's getting late there
[01:03] <Zuph> jcoxon: No, pester us. We have short attention spans.
[01:04] <Josh__> hiya guys, does anyone know of a good manual or step by step guide at how to set up a gps + microcontroller + narrowband fm transmitter to work on my weather balloon project? i'm a person with electricity knowledge that exceeds at wiring a plug so a 'for dummies' guide would be perfect :D
[01:04] <Josh__> i guess i pestered at the right time ^^ :S

[01:40] <juxta> hey natrium42, have you played with VIA mini itx boards?
[01:40] <natrium42> some years ago
[01:42] <juxta> I have one to setup as a remote recieve site at the moment, but i've noticed they're pretty cheap on ebay & was thinking of getting one to tinker with some more
[01:42] <juxta> what were your thoughts on them?
[01:42] <natrium42> just the mobo?
[01:42] <natrium42> mine had some nasty bug with pci bus or something
[01:43] <natrium42> it couldn't use network card and hard drive at the same time
[01:43] <natrium42> and system was very unstable
[01:43] <natrium42> juxta: have you seen the asus thin clients?
[01:43] <natrium42> i'd get one of those
[01:44] <natrium42> it's like a netbook but without screen
[01:45] <RedWagon_> juxta: I've used a couple VIA mini itx boards
[01:45] <RedWagon_> one is running pfSense for my router and the other has been running for a couple years at the photo studio I used to work at as a file server
[01:46] <natrium42> http://en.wikipedia.org/wiki/ASUS_EeeBox_PC
[01:46] <RedWagon_> they're not as fast as the Atom and I wouldn't recommend it for a desktop, but for specialized dedicated servers they're perfect
[01:47] <RedWagon_> the Eee box is also nice, we use them as the cafe computers at work. Just make sure to get the dual core nVidia Ion model
[01:48] <natrium42> RedWagon_: then again, netbook would be probably just a bit more expensive
[01:48] <natrium42> and you get the lcd
[01:49] <RedWagon_> what is this for?
[01:49] <SpeedEvil> https://www.genesi-usa.com/store/details/11
[01:49] Action: RedWagon_ didn't read back very far
[01:49] <SpeedEvil> for routery stuff
[01:49] <RedWagon_> ah, then go VIA, much cheaper
[01:50] <SpeedEvil> Though arm.
[01:50] <natrium42> http://www.plugcomputer.org/
[01:50] <natrium42> :D
[01:50] <natrium42> linux computer in a power adapter size
[01:50] <natrium42> though it's arm
[01:51] <natrium42> $99
[01:52] <RedWagon_> arm? what model are you looking at?
[01:52] <SpeedEvil> yeah - the other thing has builtin wifi, and hdmi
[01:52] GeekShadow (~Antoine@reactos/tester/GeekShadow) left irc: Quit: The cake is a lie !
[01:52] <RedWagon_> hdmi for routery stuff?
[01:53] <SpeedEvil> well - router/thin client/...
[01:53] <natrium42> RedWagon_: PlugComputer
[01:54] <RedWagon_> SpeedEvil: ah. If you're running an X server the Eee box might be worth it, the VIAs are pretty weak
[01:56] shipit (~sumeet@adsl-63-200-129-20.dsl.snfc21.pacbell.net) left irc: Remote host closed the connection
[01:56] <RedWagon_> with the VIA you won't have much of a GPU so most of the work will be done by the CPU and with a single core 1.5Ghz processor you can't afford to loose much.
[01:58] <gartt> Is there a UAV channel?
[01:58] <gartt> This is mostly balloons, isn't it?
[01:58] <SpeedEvil> I don't thin there is a special UAV channel.
[01:58] <SpeedEvil> Id ont't hink anyone here would object to UAV talk.
[01:59] <gartt> Just curious

[07:15] <jcoxon> yay my code seems to be working still
[07:16] <natrium42> yo jcoxon
[07:16] <natrium42> i added the thing
[07:16] <natrium42> but i found a bug mentally
[07:17] <natrium42> gonna fix :)
[07:17] <jcoxon> oh
[07:17] <jcoxon> whats the bug?
[07:17] <natrium42> i don't check for callsign in predictions for the special case
[07:17] <natrium42> and there is a racing condition
[07:18] <natrium42> oh, nvm, first thing is false
[07:18] <natrium42> so racing condition...
[07:19] <jcoxon> hmmm
[07:19] <jcoxon> racing condition only affecting this flight or all flights?
[07:19] <natrium42> just for the special case
[07:19] <natrium42> wait, what's the callsign for satellite?
[07:19] <natrium42> i can fix it easily
[07:19] <jcoxon> wb8elk2
[07:19] <jcoxon> the same as HF
[07:19] <natrium42> i mean, callsign for receiver
[07:19] <jcoxon> Orbcomm currently
[07:20] <natrium42> are you going to leave that?
[07:20] <jcoxon> its hard coded into the script
[07:20] <jcoxon> yeah don't see why not
[07:20] <natrium42> ok, then i can use it :)
[07:20] <natrium42> it's a hack anyway
[07:20] <jcoxon> hehe
[07:20] <jcoxon> eek - sounds complicated
[07:20] <natrium42> nope
[07:20] <natrium42> it's just a f ew lines
[07:21] <jcoxon> so now we should get a 'seamless' merging of the sat + HF data

[07:23] <natrium42> gets the latest complete line from DB and overwrites the one from HF
[07:23] <jcoxon> i see

[09:58] <fsphil> it asks for date(s) of flight(s) .. or something similar. so you could do a request for multiple launches over a range of days

[10:00] <fsphil> excellent - are you aiming for a spring launch?

[10:01] <GW8RAK> If all goes according to plan, I'm hoping for end April. It's been going on a long time and although I'd like a mobile phone as a backup, if I can't get it to work, I'll launch without.
[10:03] <GW8RAK> Most recoveries are okay without and I have a little homebrewed VHF beacon which I could activate when on the ground as a homing beacon. It's about 500mW out and detectable at some range.
[10:03] <GW8RAK> Hopefully we'll have some information about insurance this week.
[10:03] <fsphil> good idea
[10:04] Darkside (~Darkside@hpavc/darkside) left irc: Ping timeout: 240 seconds
[10:04] <GW8RAK> If we can get insurance, then we can launch as an official Air Cadet activity.
[10:04] <GW8RAK> Otherwise, it'll just be an informal group of people.

[10:24] <Dooberry> ahhh, perhaps a little too far to travel from London :p
[10:25] <GW8RAK> But with luck you'll hear it.
[10:34] <Darkside> hey vk5zsn
[10:35] <vk5zsn> hi
[10:35] <vk5zsn> didnt know if you were on
[10:35] <Darkside> my laptop is currently rendering some HD video, so everything is a bit slow
[10:36] <Darkside> so the predictor is putting balloons from adelaide a bit north-east of swan reach, and balloons from buckland park up near blanchetown
[10:39] <vk5zsn> ok have the truck running and a station in the shack also
[10:39] <Darkside> ok
[10:40] <Darkside> i've for my R10 going
[10:40] <Darkside> but my antenna isn't good for this frequency (its a UHF CB 6dBi)
[10:40] <Darkside> the digisondes dropped of pretty quickly for me last night
[10:40] <Darkside> really can't wait until i'm upstairs, will be so much better
[10:41] <vk5zsn> is juxta about?
[10:42] <Darkside> he was, dunno where is his now
[10:42] <Darkside> he was going to be listening out too
[10:42] <Darkside> and was interested in collecting them
[10:42] <Darkside> if theres multiple sondes, we could do one each
[10:50] <fsphil> Dooberry, you're welcome to come but you'll have to find your own way ;-)
[10:50] <Dooberry> haha very kind of you!
[10:51] <Dooberry> I do need to pop along to someone's launch sometime soon

[11:10] <Darkside> cmonn, they should be preparing now
[11:10] <Darkside> my R10
[11:11] <juxta> shenki, if you had a receiver you could likely here them from your house before they actually launched
[11:11] <Darkside> i heard them last night as soon as they launched, couldn't hear it on the ground

[11:12] <fsphil> (b)
[11:13] <Darkside> fsphil: waiting for them to be launched at the moment, should be any minutes now
[11:14] <Darkside> hmm we should set up a way to pull position data out of sondemonitor and put it on spacenear.us, so we can chase easier
[11:14] <vk5zsn> stilla few air craft on approach
[11:14] <Darkside> also we could use the car positions to help work out where everyone is
[11:14] <Darkside> vk5zsn: ahh, they wait for that i guess
[11:14] <Darkside> vk5zsn: got the ADS-B receiver out?
[11:14] <vk5zsn> i thin when the aircrft have landed then they release
[11:15] <shenki> ADS-B?
[11:15] <vk5zsn> no i dont have it on
[11:15] <vk5zsn> SSR receiver
[11:15] <Darkside> shenki: Automatic dependent surveillance-broadcast
[11:15] <vk5zsn> for radar transponder on aircraft

[11:15] <shenki> ah cool
[11:15] <shenki> what freq is that on?
[11:15] <vk5zsn> we used it at the horus launch

[11:21] <Darkside> hmm
[11:21] <Darkside> well the predictions are moving closer throughout the week, aren't they?
[11:21] <Darkside> so we have a better chance of catching one if they do launch digi-sondes
[11:22] <juxta> yeah
[11:22] <Darkside> well, i guess we keep an ear out each night
[11:22] <juxta> ping jonsowman
[11:22] <Darkside> and be ready to head off at a moments notice

[11:23] <Darkside> haha
[11:24] <Darkside> also we're considering doing a video launch next monday

[11:25] <vk5zsn> that sounds easy. I'll be at work of course !
[11:27] <vk5zsn> juxta you'll need to pick up the HAB kit from my place over the nex few days
[11:27] <juxta> yep will do
[11:27] <Upu> Tim got his payload back
[11:27] <juxta> was looking for a coax adapter I had in there
[11:27] <vk5zsn> possibly we may meet up if we go out sonde chasing !
[11:27] <Upu> someone needs to show him how to cut a hole in his payload that doesn't obscure the camera
[11:28] <juxta> haha yeah I noticed that too Upu
[11:28] <Darkside> as soon as this sonde goes over the hills i'm going to loose it..
[11:28] <Darkside> vk5zsn: do you have any working digital sondes?
[11:29] <vk5zsn> Yes I do
[11:29] <Darkside> i might see if we can make a way to push data from sondemonitor into spacenear.us, for if we go out sonde chasing
[11:29] <GroupO> Hibby: ping
[11:29] <Darkside> i think sondemonitor logs data to files, so i can probably read that data and construct a fake sentence to send to spacenear.us
[11:30] <shenki> juxta: did you notice on saturday that the case cars reported altitude and ascent rate
[11:30] <Darkside> i thought it was just speed
[11:30] <Darkside> in m/s
[11:30] <vk5zsn> check the gps output. the sonde fix may be sent out of a serial port. You cound use that
[11:30] <juxta> haha we should probably remove the asc rate for cars

[11:31] <Darkside> could i borrow a digi-sonde for a few days?
[11:31] <juxta> Darkside, yeah as Adrian says it will output to a serial port as plain old NMEA
[11:31] <Darkside> hmm, but if i can get more data i should
[11:31] <Darkside> may as well try and plot pressure, temp, etc on there
[11:32] <Darkside> even if its not properly calibrated
[11:32] <juxta> the digi's seem to be
[11:32] <juxta> calibrated, that is
[11:32] <Darkside> well, if i can get a digi-sonde, i'll make it work
[11:32] <Darkside> because i can see the use of that
[11:32] <Darkside> i think we need to get a local clone of spacenear.us going, so we don't mess with other people when we do this though
[11:33] <vk5zsn> i'll drop one off. also hack into the eeprom
[11:33] <vk5zsn> get ready for a major hacking session
[11:33] <Darkside> heh
[11:33] <Darkside> yeah
[11:34] <Darkside> ok, i think i got the source to spacenear.us from natrium a while back
[11:34] <Darkside> but i don't think i got the databases to run it
[11:34] <juxta> I'll get one running
[11:35] <Darkside> juxta: cool
[11:35] <Darkside> hmm, but we still need to get a clone of rob harrison's site too
[11:35] <juxta> I'll chat to Rob about it
[11:35] <Darkside> since thats where spacenear.us will pull the data from
[11:36] <Darkside> ok
[11:36] <juxta> if he's happy for us to go ahead then I'll do that too
[11:37] <Darkside> ok
[11:37] <Darkside> i just figure it could be a useful way of coordinating between chase cars if we go BOM chasing
[11:37] <Darkside> and if we can get data from digi sondes into it, it would be even more useful
[11:38] <Darkside> im going to get another cup of tea

[12:12] <Lunar_Lander> there has been an interesting air density meter, called betasonde
[12:13] <Lunar_Lander> the idea was that there was an array of geiger counters mounted at a distance from a piece of Promethium
[12:13] <Lunar_Lander> and the count rate could then be converted to air density
[12:14] <fsphil> maybe you could measure sound, from a buzzer. as the pressure decreases, so does the volume
[12:15] <fsphil> though the speaker would probably freeze
[12:16] <Lunar_Lander> yes

[13:28] <juxta> how are you doing?
[13:28] <jonsowman> fine thank you :) how are you?
[13:29] <juxta> going well - I was going to ask you about calling your predictor using something automated :)
[13:30] <jonsowman> okay, what output are you after?
[13:30] <jonsowman> just a landing site? a map? a full flight path?
[13:30] <juxta> is there an easy way to submit a scenario - ie via POSTing it?
[13:31] <juxta> basically the whole flight path
[13:31] <juxta> as the predictor would normally show it
[13:31] <jonsowman> so the form data is POSTed to the server in an AJAX request
[13:32] <juxta> alright
[13:32] <jonsowman> just having a look at the moment to see what could be done
[13:32] <juxta> does the server then return a URL that the client needs to load up?
[13:34] <jonsowman> the server validates the submitted data and tried to begin a prediction run, and returns the uuid of the prediction to the client
[13:34] <juxta> alright
[13:34] GeekShadow (~Antoine@reactos/tester/GeekShadow) joined #highaltitude.
[13:34] <jonsowman> once the client knows a prediction has successfully begun, it uses the uuid it knows to poll for a json file on the server which contains information about the progess
[13:35] <juxta> yeah
[13:35] <jonsowman> then once that progress file says the prediction has finished, the client fires off another ajax request to the server to retrieve the flight path
[13:35] <juxta> basically I'd like to have a link (be it via a caller script or whatnot) that'll lead to a prediction for a given set of parameters
[13:35] <juxta> ie - always point to tomorrow's prediction at 00:00am
[13:36] <jonsowman> ahh I see
[13:36] <jonsowman> right
[13:38] <jonsowman> so when you click it, it runs the prediction and displays the result?
[13:38] <juxta> yup
[13:39] <juxta> i'm about to head to bed now, but I'll have a play in the morning
[13:40] <jonsowman> okay, I shall have a think about it
[13:40] <jonsowman> if it's not directly doable, I'm sure I can add it :)
[13:40] <juxta> drop me a line if you think up any nifty ideas
[13:41] <jonsowman> yep, will do :)
[13:41] <juxta> otherwise I'll hack something shamefully bad together ;p

[13:41] <Darkside> being able to get predictions for earlier dates would be interesting
[13:41] <Darkside> to see how close the preditcion is to reality
[13:42] <juxta> noaa purge the datasets i believe
[13:42] <juxta> but you can grab predictions you already ran

[15:45] <Laurenceb> are you sure the terminal is setup right?
[15:46] <Hibby> Well, I'm getting the expected string at the expected length, after initialising the module as suggested on the ukhas page. Then go on to turn off the nmea strings as I feel the ublox 00 string is more worth my effort, and after a while with loads of sky I get utc time on both, but no other data

[15:51] <Laurenceb> hmmm
[15:51] <Laurenceb> so its sending data packets?
[15:52] <Hibby> yep, just not getting any location fix at all.
[15:52] <Laurenceb> or just one packet when it gets UTC
[15:52] <Laurenceb> constant blank packets?
[15:53] <Hibby> plenty packets. It polls for a new UBLOX string every 2 seconds (in this example, becuase I don't like waiting), parses it and spews the output formatted as i want to stdout
[15:53] <Laurenceb> ok, thats good so far
[15:53] <Laurenceb> id check the power supply
[15:53] <Laurenceb> also some people have reported damaged atns
[15:54] <Laurenceb> *antenni
[15:54] <Laurenceb> in my experience it does this when there is power supply noise
[15:54] <Hibby> Aye, was suspecting an antenna fault. as for power supply
[15:54] <Hibby> interesting. Power's currently coming from laptop...
[15:55] <Hibby> may be the cause.
[15:55] <Laurenceb> hmm...
[15:55] <Laurenceb> 3.3v regulator?
[15:55] <Hibby> 3.3 out on an arduino mega
[15:55] <Laurenceb> from onboard ldo or the ftdi?
[15:56] <Hibby> ftdi - USB is the only power source here.
[15:57] <Laurenceb> theres no way you'll get a fsa running off an ftdi regulator
[15:57] <Laurenceb> or any ublox for that matter
[15:57] <Hibby> that explains it then
[15:57] <Laurenceb> heh
[15:57] <Hibby> current draw too high for the output of the reg?
[15:58] <Laurenceb> you need a good quality 150ma ldo with some decent decoupling caps
[15:58] <Laurenceb> yes, and its too noisy
[15:58] <Laurenceb> doesnt respond fast enough etc etc
[15:58] <Laurenceb> ublox5 is a bit of a beast to power
[15:58] <Laurenceb> it might use <50ma on average but...
[15:59] <Laurenceb> the digital logic is doing stuff that requires intermittent ~100ma bursts of current
[16:00] <Hibby> Cool. Reckon it can be done via a 9V battery into arduino's internal regulator, or am I going to have to play with regulators before it gets in that far
[16:00] <Laurenceb> and if the voltage does anything bad whilst thats happening the RF hardware starts playing up and it cant get a lock
[16:00] <Laurenceb> id make your own reg circuit, as you need 3.3v
[16:01] <Hibby> aye, cool. Makes sense... brain was still trying to power it from arduino.

[18:37] <fsphil> work
[18:37] <jcoxon> yes
[18:37] <jcoxon> its hysplit as well so its super advanced for floating balloons
[18:37] <jcoxon> fsphil, did you know we've got 139 downloads of dl-fldigi r115.1
[18:38] <fsphil> impressive -- that's not been up long
[18:43] <m1x10> is any facebook group in existance around habing?

[18:55] <rjharrison_> Evening all
[18:55] <jcoxon> hey rjharrison_
[18:55] <fsphil> g'day rjharrison_
[18:55] <rjharrison_> hey jcoxon you back in blighty?
[18:55] <jcoxon> yup
[18:55] <rjharrison_> Hi fsphil you set for launch soon
[18:56] <fsphil> this weekend if everything comes together
[18:56] <jcoxon> rjharrison_, i've got a listening server question for you
[18:56] <rjharrison_> jcoxon Talk went well at leeds uni
[18:56] <rjharrison_> fire away
[18:56] <rjharrison_> Upu was there
[18:56] <jcoxon> if spacenear.us was to go down - would the listening server hang?
[18:56] <Zuph> pong jcoxon
[18:56] <rjharrison_> no
[18:56] <jcoxon> Zuph, is the sim over? is everything displayed correctly - looks like there was a jump in data points
[18:56] <Upu> was a good one indeed :)
[18:57] <jcoxon> rjharrison_, excellent
[18:57] <Upu> Evening Rob
[18:57] <rjharrison_> it just curls out the data and it will basically send it to /dev/null
[18:57] <rjharrison_> hi Upu
[18:57] <Zuph> jcoxon: Sim is over for now. Still ironing out minor glitches in parsing software.
[18:57] <Upu> interesting crowd, lots of meterologists I think :)
[18:57] <rjharrison_> jcoxon if we wanted to we could send the data to two servers though atm it goes to the rob... one
[18:57] <Zuph> jcoxon: the issue appears to be that the HF telemetry and sat telemetry are mapped to the same track.
[18:58] <mattltm> I am blaming this on you fsphil. Its blowing a gale (22mph gusts), its cold and I now have a huge beam waiting for me to be brave enough to lift it into the air!
[18:58] <jcoxon> Zuph, oh thats a feature!
[18:58] <rjharrison_> I will upgrate the backup one to the latest version
[18:58] <Zuph> jcoxon: our sat telemetry is simulated GPS, while the HF telemetry is not simulated right now.
[18:58] <fsphil> muhaha !
[18:58] <jcoxon> rjharrison_, yeah that would be great
[18:58] <Zuph> jcoxon: So right now our HF is reading solidly at wb8elk's farmhouse, while the Sat is reading SNOXX IV
[18:58] <rjharrison_> jcoxon I have all the kit to start dev. on the 2 way coms
[18:59] <jcoxon> Zuph, i understand - hence you stopped listening for hte HF
[18:59] <Zuph> yep
[18:59] <jcoxon> rjharrison_, nice
[18:59] <jcoxon> Zuph, not worried that you haven't yet got a gps lock with the hf setup?
[19:00] smea (~smealum@89-156-20-102.rev.numericable.fr) joined #highaltitude.
[19:00] <Zuph> jcoxon: Nope, since it's currently sitting in the bottom floor of a 3 story building in a dense urban area.
[19:00] <rjharrison_> It's going to be similar to the CUSF stuff on the their board as it uses the CC1110 chip
[19:00] <Zuph> I imagine it will light right up as soon as we wheel it outside.
[19:00] <jcoxon> Zuph, i see, you happy with the data being merged
[19:00] <jcoxon> ?
[19:00] <jcoxon> will give a nice flight path i hope
[19:00] <Laurenceb_> rjharrison_: what will you use for CC1110 programming?
[19:01] <Zuph> For flight, absolutely. For testing, it will make the tracks look weird :-p
[19:01] <jcoxon> okay, well i'm pleased with myside
[19:01] <jcoxon> worked without any interference i think
[19:01] <jcoxon> and coped with your dirty data points
[19:02] <rjharrison_> Laurenceb I have a dongle and the kickstart IAR iirc
[19:02] <Laurenceb_> oh neat
[19:02] <Zuph> jcoxon: Sorry about that, those should disappear with real data :)
[19:02] <rjharrison_> Zuph CRC should sort that hopefully
[19:03] <jcoxon> rjharrison_, hehe its not crc - they are purposeful dirty data points
[19:03] <Zuph> rjharrison_: Well, our GPS simulator gives inentionally very weird data with valid checksums to check our fligth algorithms.
[19:03] <jcoxon> Zuph, looks like the predictor is all setup as well
[19:03] <Zuph> jcoxon: so it does. natrium42 and tyler were working on that, iirc
[19:03] <jcoxon> great
[19:04] <rjharrison_> Laurenceb http://uk.farnell.com/jsp/search/productdetail.jsp?SKU=1844962
[19:05] <rjharrison_> I got this when I was at farnels the other day along with some 434 dev boards to go with 868 ones
[19:05] <jcoxon> Zuph, is there anything else you need worked on?
[19:05] <jcoxon> got a couple of free evenings
[19:05] <rjharrison_> jcoxon few more people on here these days
[19:05] <Upu> just a bit :)
[19:06] <Upu> just finished my filler the glue is drying
[19:06] <rjharrison_> Upu cool

[20:13] <fsphil> the signal is fading in and out, I wonder if it's reflections from aircraft
[20:13] <fsphil> there's an airport between me and this guy
[20:13] <mattltm> Got that here too
[20:13] <mattltm> Lots of fading tonight.
[20:13] <fsphil> he's getting contacts from all over the place
[20:14] <LazyLeopard> What freqs?
[20:14] <mattltm> Just heard bedfordshire!
[20:15] <fsphil> GI4SNA on 143.8526 I think
[20:16] <LazyLeopard> 144 or 145 I'd hope...
[20:16] <fsphil> lol
[20:16] <fsphil> yea...
[20:16] <Dan-K2VOL> get HF frequency requests for SpeedBall-2 in to Bill Brown, it may be selectable between 2 HF freqs (likely in same band)

[20:30] <jcoxon> middle
[20:30] <jcoxon> or has it just been running all day
[20:30] <jcoxon> ?
[20:31] <Zuph> Huh, I guess Bill got the telemetry parsing working again :)
[20:31] <jcoxon> hehe
[20:31] <jcoxon> check out spacenear.us

[20:55] <LazyLeopard> Dan-K2VOL: Of late it seems to have been all HR607 and Smali pirates... :/
[21:00] <Zuph> jcoxon: The way we had solved this: If the difference between the new point and the previous point is greater than 5 degrees in any direction, ignore it.
[21:00] <jcoxon> yeah that was what i was thinking
[21:01] <jcoxon> however in theory we aren't going to have you dodgey points
[21:01] <Zuph> yeah
[21:01] <jcoxon> i think the bigger risk is dirty points from HF
[21:01] <Zuph> jcoxon: Sat telemetry will be incoming at least every hour, and we'd have to be moving greater than 200 knots to move more than 5 degrees in an hour.
[21:02] <jcoxon> as its only a XOR checksum
[21:03] <Zuph> hmm

[21:52] <mattltm> good job :)
[21:53] <mattltm> yes, miles
[21:53] <fsphil> most of those points are for being low power I think

[22:37] <fsphil> oooh maybe next time I'll have the 2I0 call, might see if I can get more power
[22:37] <mattltm> I wont fit on top of my defender 110!
[22:37] <fsphil> lol
[22:37] <mattltm> Yay. Me and you both maybe.
[22:37] <LazyLeopard> Intermediate exams booked?
[22:37] <mattltm> No, my test is mid April.
[22:38] <fsphil> our exam is on the 11th
[22:38] <LazyLeopard> Good luck.
[22:39] <fsphil> thanks
[22:40] <fsphil> I haven't met the rest of the people taking the course yet, should be fun
[22:40] <mattltm> Cool. Got your eyes on an M0?
[22:40] <fsphil> not for a while I don't think, it's a long course
[22:41] <fsphil> not something I'd fancy studying at home for
[22:43] <LazyLeopard> ...but no required practicals, so home studying is an option.
[22:43] <fsphil> mattltm, you're not first anymore ;)
[22:43] <mattltm> Damn it!
[22:43] <mattltm> Wellthe glory was mine for a while :)
[22:44] <fsphil> and I'm not last yay :D
[22:44] <mattltm> Good job.
[22:45] <mattltm> did you entre last month?
[22:45] <fsphil> "2x15ele CueDee "
[22:45] <fsphil> yikes
[22:45] <fsphil> missed last months, can't remember why now
[22:47] <mattltm> I have to work 100khz away from G8HGN when his beam is pointing at me.

[22:52] <LazyLeopard> Camb Hams seem to have had fun.
[22:57] <fsphil> MI0SMK is on there, wonder why I didn't hear him
[22:57] <fsphil> another operator with a silly tower
[22:58] <mattltm> It's only silly because you don't have one :)
[22:59] <fsphil> so true
[23:00] <fsphil> mmm.. balloon mounted vertical
[23:00] <mattltm> Balloon mounted yagi would be interesting :)
[23:00] <fsphil> aiming it would be fun
[23:01] <mattltm> Hang it from a fast servo?
