[07:01] <jonsowman> yep
[07:01] <jonsowman> plus a gsm tracker
[07:02] <jonsowman> so we should have a decent amount of redundant tracking hardware

[07:28] <daveake> UpuWork Does your house lean over as you rotate that monster?
[07:33] <number10> he's been asked not to rotate it towards cambridge before the launch just incase the baloon hits it on the way up
[07:34] <daveake> lol
[07:35] <daveake> Usually we only need to call ATC to launch, but he needs to call them just to aim that thing?

[08:12] <daveake> damn
[08:13] <eroomde> i did some sums last night
[08:13] <eroomde> i can match upu's yagi with a 1.8m dish
[08:13] <eroomde> I don;t have a 1.8m dish
[08:13] <waner> Hello! I'm having troubles in using the ntx 2 and an arduino uno.... dl-fligi should write "RTTY TEST BEACON RTTY TEST BEACON", but I get " |YQb9|YTtd,IL2@EEb9|YTtd|YQb9|YTtd,IL@Eb9|YTtd|YQb9xYTtd,IL2@Eb9|YTtd|YQb9|YTtd,IL2@Eb9|YTtd|IQb9|YTtd,IL2Eb9|YTtd|YQb9|YTtd,IL2@Eb9|YTtd|YQb9|YTtd,IL2@Eb9|YTtd6|9|YTtd,IL2@Eb9xYTtd|YQb9|YTtd,If2@Eb.T|YTtd|" which seems quite hard to read.....any idea? Thank you for your help!
[08:13] <daveake> for small values of "can" then
[08:14] <eroomde> well, dave the electronics surplus man has a 2m dish in his nuclear bunker
[08:14] <eroomde> which he wants to get rid of
[08:14] <daveake> :)
[08:14] <daveake> waner: Try the Rv button in fldigi
[08:15] <daveake> And of course check baud rates/parity/etc
[08:15] <eroomde> if this works you'll be worshipped as a shaman daveake
[08:15] <eroomde> 'try Rv'
[08:15] <eroomde> OMG IT WORKS U GENIUS!!!!
[08:15] <daveake> lol
[08:15] <eroomde> best tech support call in hab
[08:16] <waner> It works with the Rv button! Wow! Thank you!
[08:16] <eroomde> :P
[08:16] <daveake> <can't tell if serious>
[08:17] <waner> than THE best tech support I've ever seen! Thank you again!
[08:17] <daveake> <still can't tell> :)
[08:21] <eroomde> but yeah, i don;t think i'd need planning permission to put a dish up on the test stands
[08:22] <eroomde> it seems like anything goes there
[08:22] <eroomde> and the gain at 5GHz is 38dB which is serious!
[08:22] <UpuWork> Actually
[08:22] <eroomde> we can fly 25mW on 5GHz according to IR2030
[08:23] <UpuWork> which example are you using waner ? I changed the code so its one wire
[08:23] <eroomde> which is what first made me think about a dish
[08:23] <UpuWork> thats alot of gain
[08:23] <eroomde> indeed
[08:23] <eroomde> the free space path loss obviously kicks in
[08:23] <eroomde> but it's still quite a bit up 10mW 434mhz even when you factor that in
[08:24] <craag> it is a lot up I think.
[08:24] <UpuWork> live video!
[08:24] <eroomde> 17dB i think i calculated
[08:24] <eroomde> well, it might not be bonkers an idea o try
[08:24] <eroomde> especially as no badnwidth limit (pragmatically speaking) at 5ghz
[08:25] <daveake> waner Try tuning down in frequency just a little on the receiver. The received audio should go up in frequency when you do. If it goes down, you're tuned wrong, in which case keep tuning down till the audio disappears then comes back again. At that point you'll be tuned in correctly and you can switch Rv off.
[08:25] <UpuWork> Have you got the radio on LSB or USB ?
[08:26] <waner> Upuwork: I use the code on the guide webpage http://ukhas.org.uk/guides:linkingarduinotontx2
[08:27] <UpuWork> yeah just trying to work out why you have to press RV
[08:27] <UpuWork> Are you using the old 2 wire example
[08:27] <UpuWork> or the new one I wrote 2 days ago with 1 wire ?

[08:36] <waner> UpuWork: I'm using a Cinergy TstickRC HD, with SDR# set on DSB and dl-digi set on USB, maybe it's the key of the answer ...
[08:36] <eroomde> waner: you've done the thing we highly discourage (don;t worry tho it's not too late!) which is copy and paste without understanding
[08:36] <UpuWork> I wonder if you're not listening to the actual signal and a copy of it
[08:36] <Darkside> waner: youw ant SDR# set to USB
[08:36] <Darkside> not DSB
[08:37] <UpuWork> what Darkside says as well
[08:37] <Darkside> you're likelty receiving a mirrored version of the signal
[08:37] <Darkside> set SDR# to USB and you should be fine
[08:37] <UpuWork> the one wire example should need RV setting
[08:38] <daveake> shouldn't shirley?
[08:38] <UpuWork> btw I changed the instructions on the linking an Arduino to NTX2 to use only one wire
[08:38] <UpuWork> shouldn't yes
[08:38] <UpuWork> I'm going to update that post with eroomde's first law of not pissing off UKHAS later
[08:38] <daveake> 1-wire is good - one less thing to get wrong
[08:38] <UpuWork> thou shalt not copy n paste code for it will end in suffering
[08:39] <daveake> thou shalt not copy n paste comments for it will end in suffering
[08:39] <UpuWork> :)
[08:42] <waner> Darkside: So it's working in setting SDR# on USB and taking off the Rv option ;)
[08:42] <UpuWork> yeah that makes more sense
[08:44] <daveake> Excellent. Rv is for when something else is wrong, but it's always best to fix the root cause

[08:47] <eroomde> no problem! it might be worth re-writing it from scratch once you've digested it
[08:47] <eroomde> that way you can really know
[08:47] <eroomde> it's alwats the details that get you, off-by-one errors and stuff. that's the difference between roughly knowing and actually knwing
[08:48] <MrScienceMan> waner: RTL dongles are no longer supported by SDR#
[08:48] <MrScienceMan> if you are running the latest versino
[08:48] <craag> You can add the plugin and edit the config manually to add it back in though.
[08:48] <MrScienceMan> yeh
[08:49] <MrScienceMan> it crashes everytime i move the center frequency

[08:49] <craag> I've just been using an old version to be honest, new enough to have 250ksps.
[08:50] <Adam_> "50 baud 8N2" - what does that mean? how does the baud rate convert? is that the number of GPS co-ordinates sent per minute?
[08:51] <UpuWork> it means the data rate is 50 baud sent 8 bits at a time with no parity bit and 2 stop bits
[08:52] <UpuWork> it has nothing to do with the GPS
[08:52] <UpuWork> just the rate you're transmitting whatever data your transmitting at
[08:52] <Adam_> ah ok, but still has a CRC?
[08:53] <Adam_> or would that just add delay to each packet?

[08:54] <Adam_> you're right :)
[08:54] <UpuWork> when you transmit data whatever it is (ignore the GPS)
[08:54] <Adam_> i'm still learning
[08:54] <UpuWork> you can check sum the data
[08:55] <UpuWork> that just means when it gets to where its going they can ascertain if they have recieved it correctly
[08:55] <Adam_> yes, like odd / even parity bit
[08:55] <UpuWork> in short it works like this
[08:56] <UpuWork> you have a microcontroller
[08:56] <UpuWork> it reads some data in from the GPS, from whatever sensors you've decided to fly
[08:56] <UpuWork> it puts all the information into a string
[08:56] <UpuWork> and then it transmits this via the radio or via GSM if you are using that
[08:57] <UpuWork> so lets break that down
[08:57] <UpuWork> ignore the GPS and the sensors
[08:57] <UpuWork> get the Arduino talking to the radio first

[08:58] <UpuWork> is the important bit
[08:59] <Adam_> ok
[08:59] <UpuWork> if you understand how that works you'll be in better stead to work on connecting the GPS to the Arduino and then finally link to the two together
[08:59] <Adam_> yes, i've got that setup at the moment
[09:00] <UpuWork> ok go break it
[09:00] <Adam_> but i'm waiting for my TV receiver to arrive today or tomorrow to listen to the transmissin

[09:10] <daveake> It'll only get to 5-6km up so tracking is harder if you're a long way away
[09:10] <Adam_> it'll launch with just a small balloon then?
[09:10] <Adam_> ah ok
[09:11] <daveake> Yes, a large party balloon, basically
[09:11] <daveake> foil one. They don't stretch.
[09:11] <Adam_> i don't have a radio, only a TV receiver haha
[09:11] <kokey> the wind going to take it up north on sunday?
[09:11] <daveake> Not done a prediction for a 3 days, but then it said up north past Leeds
[09:11] <daveake> Trying to fly past Upu :)
[09:11] <kokey> I needed a kettle chord plug for a PC last night
[09:12] <kokey> in a hurry
[09:12] <kokey> went to PC world
[09:12] <kokey> paid £13.90 for one!
[09:12] <Adam_> WOW.
[09:12] <daveake> Oh wow
[09:12] <Adam_> I got one off ebay ages ago for like £2 inc postage :)
[09:12] <fsphil> !!
[09:12] <Adam_> that's crazy margins
[09:12] <kokey> I knew they rob you on those little exras, but that is a new level of bad
[09:13] <daveake> It's annoying when that happens. I was at a customer site once and needed one, and had to go to the local PC Weld. I have loads at home but they weren't with me :(
[09:13] <kokey> I'm sure maplin would have been much cheaper
[09:13] <kokey> yeah that's the shame, like when I was working for rackspace we got one with each PC but we used different plugs in our racks, so we used to throw away boxes of the stuff

[09:35] <upix> I'm planning on adding a BNC on ezcap dongle and I have two choices in mind: 1) Leave TV aerial and solder short coax with BNC in parallel 2) Solder TV aerial out and replace it with BNC dirrectly. I would prefer the first, but I don't if that would't weaken the signal. What can you recommend?
[09:35] <Darkside> it probably won't make much difference either way
[09:36] <Darkside> though i'd probably go with #2
[09:38] <griffonbot> Received email: Adam Cudworth "Re: [UKHAS] Launch Announcement (11th August) MONDO"
[09:39] <upix> I want to do #1 because it's nice to have both connections just in case and the to fix in the BNC connector I would have to cut a small peace of pcb (doesnt have any traces)

[09:40] <kokey> I wonder if soldering in a socket, that you can put a TV or BNC on when needed, is going to degrade performance much
[09:41] <kokey> actually, soldering in a BNC, and then making a BNC->TV female socket will probably work nicely

[10:53] <kokey> I suppose they added some NASA red tape, made it 100 times more expensive, and now it's a lander designed by committee
[10:53] <kokey> it probably has a carbon footprint meter on board, and carries printed out legal disclaimers

[13:59] <Laurenceb> three of those and some propane at 90C
[14:00] <Laurenceb> - so its supercritical and gives you ~80seconds

[15:20] <jgrahamc> Afternoon folks.
[15:20] <UpuWork> hi there
[15:21] <eroomde> afternoon jgrahamc
[15:21] <jgrahamc> I haven't been in here for a while, but I'm trying to spend time on HAB stuff.
[15:21] <eroomde> i don't think much has changed
[15:21] <jgrahamc> Had a slightly technical question: has anyone flown those tiny '808' cameras?
[15:21] <UpuWork> yes
[15:21] <UpuWork> and they jam the GPS
[15:22] <jgrahamc> That's good to know.
[15:22] <jgrahamc> Have people tried workarounds (like a faraday wrapping around the cameras)?
[15:23] <Gadget-Mac> UpuWork: What your toys URL again pls ?
[15:23] <upix> Why does a camera jam GPS?
[15:24] <UpuWork> https://www.dropbox.com/s/d00o64lm9n7fj0v/2012-08-10%2007.21.16.jpg
[15:24] <Gadget-Mac> Cos its got noisy electronics
[15:24] <eroomde> upix: for example, the image encoding chip will produce some frequencies that are the same as the gps frequency
[15:24] <nigelvh> YAY RF!
[15:24] <eroomde> most of these things are quite poorly made and seem to circumvent emi rules
[15:25] <LazyLeopard> WOMBAT today was a good example... GPS apparently fin until the cameras were turned on.
[15:25] <eroomde> jgrahamc: we wrapped one in foil and increased the physical distance from the gps antenna, aswell as having it completle electronically isolated
[15:25] <Gadget-Mac> There's CE and then there's CE
[15:25] <LazyLeopard> Cool, Upu!
[15:25] <nigelvh> Yeah, nice setup there Upu.
[15:25] <daveake> China Export
[15:26] <UpuWork> cheers it seems to work :)
[15:26] <upix> Is that a yagi?
[15:26] <daveake> I used an 808 and it didn't interfere. Upu's was a something-80?
[15:26] <nigelvh> What's the red
[15:26] <nigelvh> "peak" brick?
[15:26] <UpuWork> MDS90 ?
[15:26] <cuddykid> almost a road landing I see - lucky :D
[15:26] <jgrahamc> Thanks eroomde. I am playing around with two and will see if I experience any problems. I was planning on use the uC to control so will look at optoisolation.
[15:26] <UpuWork> house alarm
[15:26] <LazyLeopard> Looks like an alarm box.
[15:27] <UpuWork> but between you and me its empty
[15:27] <nigelvh> Ah
[15:27] <nigelvh> Good to know next time I'm over there.
[15:27] <UpuWork> I used this : http://www.aee.com/en/productshow.asp?sendid=40
[15:27] <daveake> cuddykid When you said "it seems to vary between around 850Hz and just over 1000Hz" is that wit temperature or random or something else??
[15:27] <UpuWork> "anything to declare ?" "just a 19 element yagi"
[15:27] <eroomde> jgrahamc: ferrite beads might help too
[15:27] <LazyLeopard> What rotator and what co-linear are those?
[15:28] <UpuWork> yaesu G-5500
[15:28] <cuddykid> daveake: completely random when I turned it on once it was 850Hz exactly - most of the time it's 1000Hz
[15:28] <daveake> UpuWork I'm surprised the alarm isn't simply wired up to the antenna
[15:28] <UpuWork> and the colinear is the existing Watson W-50
[15:28] <LazyLeopard> Thanks
[15:28] <UpuWork> Yagi is a Tonna
[15:28] <daveake> So when we're tracking it might just jump?
[15:28] <UpuWork> cuddykid that is very concerning
[15:29] <daveake> Try whacking it see if that makes it jump
[15:29] <cuddykid> lol, will do
[15:29] <nigelvh> You got the computer controlling the az/el rotators?
[15:29] <eroomde> yes it's very very odd cuddykid
[15:29] <eroomde> what is your circuit diagram?
[15:29] <daveake> I'd want to get that sorted before launch TBH
[15:30] <jgrahamc> Thanks eroomde.
[15:30] <Gadget-Mac> daveake: Glad someone got it
[15:30] <upix> what is this thing with cuddykid? I've must've missed something
[15:31] <eroomde> cuddykid: ping
[15:32] <eroomde> so i don;t know what your circuit diagram is, depending on the setup i wonder if some other arduino funtion is changing the port that the pin is on from being pulled high or low internally or just letting it tri-state

[15:50] <UpuWork> sharing the video when you get back ?
[15:50] <UpuWork> did it wake all the construction workers up ? :)

[15:51] <UpuWork> would love to see that if you can share it

[16:04] <jgrahamc> Really Lunar_Lander? Not sure why.
[16:04] <Lunar_Lander> I think you once gave advice to the government or so?
[16:05] <jgrahamc> Was it to do with climate change?
[16:05] <Lunar_Lander> I think so
[16:05] <jgrahamc> Perhaps because of my paper in Nature.
[16:05] <Lunar_Lander> or wait
[16:05] <Lunar_Lander> was it something with Alan Turing

[16:12] <eroomde> upix: some people do commercial flights to help fund things
[16:12] <eroomde> i think rocketboy does a number of commercial flights
[16:13] <eroomde> i have proposed and carried out with cusf a test program for parachutes for esa done with hab
[16:13] <Lunar_Lander> yeah
[16:14] <Lunar_Lander> research!
[16:14] <upix> eroomde: so you work in research?
[16:14] <eroomde> thanks Lunar_Lander
[16:14] <eroomde> upix: well, this was still when i was an undergrad
[16:15] <eroomde> so i was in research at the time
[16:15] <eroomde> i suppose
[16:16] <eroomde> now i work in the space industry and a lot of what we do is research
[16:16] <eroomde> but as part of commercial (or agency funded) contracts

[16:17] <upix> I'm 3rd year undergrad and I'm thinking where should I do masters. The main two areas atm are space and robotics. THough not so sure where should I study, cuz there aint any good programs in my country.
[16:18] <eroomde> what is your country?
[16:18] <eroomde> which*
[16:18] <upix> lithuania
[16:18] <eroomde> ah
[16:18] <eroomde> cannot help you much then
[16:20] <eroomde> i don't know of that many specifically 'space' masters, a lot of the poeple i've come across in industry just have a masters in a more normal area which they can apply to space problems
[16:20] <eroomde> but in the UK, i know that Surrey has a good program
[16:20] <eroomde> The US is very unfriendly about space things if you're not american
[16:20] <nigelvh> Over here at the University of Washington we have an Earth and Space Sciences department where you can get a degree in various space-related stuffs.
[16:20] <jgrahamc> Not an actual qualification, but MIT has put a lot of their aero/astro courses on line: http://ocw.mit.edu/courses/aeronautics-and-astronautics/

[16:25] <upix> eroomde: what kind of normal masters are you talking about?
[16:26] <eroomde> upix: in general i've found that you can learn 'stuff' on the job, but knowing the fundamental maths is a big advantage. so I'd pick a program that focusses less on industry specific 'stuff' and more of giving you a solid theoretical underpinning for whatever you might end up doing.

[16:26] <eroomde> my masters was in control theory and signal processing
[16:27] <upix> i wish i knew what i might end up doing
[16:27] <daveake> I wish I knew what I was doing
[16:27] <eroomde> which has been quite useful, though my current job requires knowing lots of thermodynamics (rocket engines), but maths being maths, and control theory having a lot of it, picking up the thermo has been not quite as hard as it might be

[16:28] <eroomde> likewise most of the signal processing I did was bayesian stuff (I guess you'd call it machine learning really) but a general understanding of inference is very useful for all sorts of things, especially anything that involves interpretting data at a non-trivial level
[16:29] <eroomde> so none of it had 'space!' written on it, but it's all been very useful
[16:32] <eroomde> also, one thing common to a lot of the best engineers i've met is that they can program

[17:18] <nosebleedkt> Because I followed that picture to build my stack
[17:18] <nosebleedkt> :p
[17:18] <jgrahamc> Yes, I did make that picture.

[17:18] <nosebleedkt> I do the mosaic with a software that Upu , told me. Microsoft ICE

[17:26] <nosebleedkt> and good (the opposite) while descending

[17:26] <eroomde> might be unstable while descending, if that's important to you
[17:26] <nosebleedkt> eroomde, yeah
[17:29] <cuddykid> how do people do the knots when the payload box is suspended from 4 points and they come together at a point (key ring)?
[17:30] <jgrahamc> On GAGA-1 I had two loops of cord going through the case. they were tied on the top using Zeppelin bends so they were separate loops. My thinking was that one could fail completely and the other loop could support the capsule.
[17:31] <cuddykid> good idea
[17:31] <jgrahamc> I believe I attached the main cord going to the parachute by typing a bowline and the two loops went through the bowline loop. It may actually have been a double bowline.
[17:31] <jgrahamc> I also then set all the knots and taped them up.
[17:33] <eroomde> i use figure-8s a lot
[17:34] <eroomde> learn how to tie one around an existing loop - ie not just tying a normal know with doubled up string
[17:34] <eroomde> that's very useful for lots of things, it also is among the strongest of knots
[17:34] <nigelvh> Figure eights and bowlines are great knots. Good enough for climbing, good enough to hold a payload.
[17:35] <eroomde> normal knot*
[17:36] <jgrahamc> According to my own blog post :-) I used a double bowline with a stopper and tape.

[17:36] <eroomde> i finish of figure-8's with a single fisherman on the dangling end
[17:37] <eroomde> UpuWork will hopefully attest to the strength of these knots
[17:37] <jgrahamc> Good idea.
[17:37] <nigelvh> A single fisherman is good, but in reality, the figure eight is good enough I just tend to use a granny to keep the loose end from flopping about.
[17:38] <eroomde> for anything proper-like, like rigging for parachutes that will get deployed, chinese fingers only
[17:38] <Lunar_Lander> jgrahamc, Zeppelin bends like with count Zeppelin?
[17:38] <jgrahamc> Yes.
[17:38] <jgrahamc> They were apparently used to tie down Zeppelins so I figured they were appropriate.
[17:38] <Lunar_Lander> ah
[17:38] <jgrahamc> I wanted some sort of bend.

[18:45] <Lunar_Lander> I say that the DS18B20 still fails
[18:45] <number10> - you should see the problem to solve as an interesting challenge
[18:45] <Adam_> upu, what to run as administrator?

[18:45] <Lunar_Lander> yeah number10
[18:46] <Adam_> i've got Zadig to install now, but windows then just re-installs the default driver.. so it's an endless circle..
[18:46] <Lunar_Lander> my professor suggested I put up the oscilloscope we have at the lab to see if a signal is transmitted on the line
[18:46] <Lunar_Lander> I found a BNC cable but no probe
[18:46] <Upu> zadiag
[18:47] <Upu> try on #rtlsdr
[18:48] <Adam_> i have, they linked me to a different version which installed the driver
[18:48] <Adam_> i'll keep trying anyway
[18:48] <Adam_> SDR keeps crashing when I press play, but i guess it's because I haven't installed the driver for the TV stick

[18:52] <craag> Adam_: Have you tried the tv stick in a different usb socket?
[18:52] <cuddykid> about ready for tomorrows launch& i think..
[18:52] <Adam_> I'll try
[18:53] <Adam_> cuddykid - good luck, yours will be the first I watch live :)
[18:53] <cuddykid> Adam_: thanks! :)
[18:53] <number10> unfortunately cant track tomorrow cuddykid - but I think there are plenty of people about

[18:55] <Lunar_Lander> ah
[18:55] <daveake> allegedly
[18:56] <cuddykid> a grotty one IIRC
[18:56] <daveake> yup
[18:56] <cuddykid> should be interesting then if it does land there!
[18:57] <Lunar_Lander> xD
[18:57] <cuddykid> currently wondering whether to take motorway or A-roads - google maps gives journey time about equal

[20:27] <Randomskk> possibly

[20:27] <Randomskk> in the "free things falling from the sky" sense
[20:27] <eroomde> jonsowman that should have been included too
[20:27] <eroomde> lol what did they say?

[20:28] <jonsowman> apart from phones
[20:28] <Randomskk> well when we turned up the site manager was v friendly and just gave it back
[20:28] <Randomskk> we got back to the car
[20:28] <Randomskk> realised the GSM tracker (duct taped to the inside lid) was missing along with the tape
[20:28] <Randomskk> texted it
[20:28] <Randomskk> still on the roof
[20:28] <Randomskk> got a position
[20:28] <Randomskk> went back and asked

[20:28] <Randomskk> all very friendly
[20:28] <Lunar_Lander> https://xkcd.com/26/

[20:30] <jonsowman> which will clearly guarantee that i never see another descent again
[20:30] <Lunar_Lander> didn't we once have a landing in a farm tree and the farmer shot the payload out of the tree?
[20:30] <jonsowman> but never mind
[20:30] <Lunar_Lander> that was a XABEN I think
[20:30] <upix> any news from cusf?
[20:30] <Randomskk> don't really need f/2.8 when taking photos of things int he sky
[20:30] <Randomskk> in the*
[20:30] <eroomde> we had a decent camera for nova [x = oh god who knows anymore but an ese test]
[20:31] <eroomde> what got the dexcent photo

[20:32] <Randomskk> "what's that..."
[20:32] <Randomskk> "gps tracker"
[20:32] <jonsowman> did they not realise we'd be able to find it since it's a... gps tracker...
[20:32] <eroomde> impressive they could figure it all out
[20:32] <jonsowman> apparently not
[20:32] <Randomskk> someone just said "give it here I'll put it in the office"
[20:32] <Randomskk> eroomde: it said "GPS tracker" on it

[20:35] <Randomskk> yea I may as well upload this segment
[20:35] <Randomskk> it is hilarious

[20:35] <Randomskk> sadly I don't have the landing
[20:35] <eroomde> (i'm politicing here)

[20:36] <Randomskk> (except without the subtle)
[20:36] <eroomde> have GBs of the stuff

[20:37] <jonsowman> Randomskk and I have stuff to exchange
[20:37] <Randomskk> sure, sounds good
[20:37] <Randomskk> before EMF would be ideal

[20:41] <Randomskk> agreed but as youtube has the option I'll remove their faces
[20:41] <eroomde> fair enough
[20:41] <jonsowman> how long is said segment?

[20:46] <jonsowman> thanks again for your help today number10
[20:46] <jonsowman> hugely appreciated
[20:46] <number10> thats ok, enjoyed it
[20:46] <eroomde> that is scary close to the road isn;t it
[20:46] <Adam_> nice image
[20:46] <Adam_> shows how close it was..
[20:46] <jonsowman> eroomde: i know
[20:46] <Adam_> very lucky
[20:47] <Adam_> sure death if it landed on the road :(
[20:47] <eroomde> the road is still a tiny target by surface area, intellectually not worried
[20:47] <eroomde> but still, blimey
[20:47] <jonsowman> yeah totally
[20:47] <eroomde> probably not sure death
[20:47] <Randomskk> steve reckons 0.1% of UK land surface outside of london is A roads
[20:47] <jonsowman> there's nothing we could have done to avoid it
[20:47] <Randomskk> which is still 1/1000
[20:47] <jonsowman> but i'm very glad it did
[20:47] <eroomde> i mean, people drive into equivalently massed pidgeons all the time
[20:48] <eroomde> i'd be surprised if it's that much jonsowman
[20:48] <Adam_> ok
[20:48] <jonsowman> 0.1% sounds too much to me
[20:48] <Randomskk> I thought so too
[20:48] M0NSA (~HeliosFA@2a01:348:117::666) left irc: Read error: Connection reset by peer
[20:48] <Randomskk> but I checked his numbers and got basically the same thing
[20:48] <eroomde> if it's that much Randomskk
[20:48] <eroomde> sorry
[20:48] <Randomskk> there's stats for length of A road in the UK
[20:48] <eroomde> that is a lot then
[20:48] <eroomde> wow
[20:48] <Randomskk> and UK total land area
[20:49] <Randomskk> and you assume 6m average width, which isn't much
[20:49] <Randomskk> and get 0.1%
[20:49] <Randomskk> and go "what."
[20:49] <Randomskk> :/
[20:49] <jonsowman> mmm
[20:49] <Randomskk> it doesn't hold water
[20:49] <Randomskk> the met office release so often
[20:49] <Randomskk> and don't land on roads
[20:49] <Randomskk> so an assumption is wrong somewher
[20:50] <jonsowman> well, pleased with Joey
[20:50] <jonsowman> was it less QRM-ey today eroomde?
[20:50] <eroomde> so uk a road coverage is about 50,000km according to google
[20:51] <Randomskk> I was a bit sad about wombat
[20:51] <Randomskk> blame gopros
[20:51] <eroomde> assume worst case that's dual carriage way
[20:51] <eroomde> a lane on a dual carriageway is 9ft = 3m
[20:51] <eroomde> so assume roads are 4 x 3 = 12m wide
[20:51] G0DJA (~chatzilla@88-97-37-189.dsl.zen.co.uk) joined #highaltitude.
[20:51] <eroomde> so a road area = 50000*12 = 600000m^2
[20:52] <eroomde> wiki uk area = 243610km^2
[20:52] <eroomde> = 243610000000m^2
[20:53] <Laurenceb__> how do i maths
[20:53] <jonsowman> good call on the building site roof Laurenceb__

[20:54] Nick change: Laurenceb__ -> Laurenceb_
[20:54] <eroomde> 0.0002%
[20:54] <eroomde> ergo, one of us has gone seriously wrong with out maths
[20:54] <eroomde> our*
[20:54] <Laurenceb_> yeah i get the same
[20:55] <Randomskk> eroomde: here
[20:55] <eroomde> jonsowman: i found joey better today, though it was a bit fadey with a time period of about 1 minute
[20:55] <Laurenceb_> erm no
[20:55] <Randomskk> eroomde> so a road area = 50000*12 = 600000m^2
[20:55] <eroomde> but could have been local factors
[20:55] <Randomskk> 50000 km
[20:55] <Randomskk> not m
[20:55] <Laurenceb_> missing 10^3 factor
[20:55] <Randomskk> you're out by 1000
[20:55] <Randomskk> i.e. 0.2%
[20:55] <jonsowman> eroomde: is was swinging a lot
[20:55] <Randomskk> the same figure I got, incidentally
[20:55] <jonsowman> *it
[20:55] <Laurenceb_> yeah
[20:55] <eroomde> Randomskk: thank you
[20:55] <eroomde> there we go :)
[20:55] <Randomskk> but that's one in every five hundred
[20:55] <Randomskk> which is insane - the met office do like 6000 a year?
[20:56] <Laurenceb_> so we'd expect something
[20:56] <jonsowman> i think it's somewhat offset by not launching when predictions are in the middle of towns
[20:56] <eroomde> that's really high
[20:56] <Randomskk> met office launch all the time
[20:56] <eroomde> i am surprised
[20:56] <Randomskk> yes I was really surprised too
[20:56] <Randomskk> it seems too high
[20:56] <Lunar_Lander> Randomskk, yeah 2000 per year roundabout
[20:56] <Randomskk> but I guess there's a lot of A roads or something?
[20:56] <Randomskk> more than that I think.
[20:56] <Randomskk> so anyway I was looking into this more at the time
[20:56] <Randomskk> with russss too and I found this
[20:56] <Randomskk> http://www.telegraph.co.uk/news/uknews/7841724/Met-Office-apologises-after-weather-balloon-crashes-into-conservatory.html
[20:56] <Randomskk> which has like, actual numbers from the met office
[20:57] <Randomskk> namely 3000 launches a year and an incident once every six months
[20:57] <Randomskk> which is typically it landing on a window
[20:57] <Randomskk> with an average payout based on the data in the article of like £300
[20:58] <number10> do the met launch from the same locations every time - or would they say decide to only launch from those locations that would get a sea landing I wonder
[20:58] <Randomskk> 0000Z and 1200Z
[20:58] <Randomskk> every day
[20:58] <Randomskk> from every site
[20:58] <Randomskk> two incidents a year is 0.06% of anything happening
[20:58] <Randomskk> with average payout of £300, i.e. expected cost per launch is about 18 pence or so
[20:58] <Randomskk> so
[20:58] <Randomskk> these two things do not add up.
[20:59] <Randomskk> it can't be 0.2% likely to hit an A road, but 3000 launches a year for years not have done so
[20:59] <eroomde> great british bakeoff is starting again
[20:59] <Randomskk> I'll let you get back to that
[20:59] <eroomde> and you thought olympics coverage was excessive

[21:00] <Randomskk> no major ukhas incidents
[21:00] <Randomskk> well
[21:00] <Randomskk> nothing really
[21:00] <Randomskk> and we're in the hundreds of launches region easily
[21:00] <Randomskk> if I was better at my stats I'd tell you how likely it is that 0.2% of landings are roads given as 300 or so haven't landed on roads
[21:01] <Randomskk> regardless something is amiss.

[21:03] <eroomde> for example, about something interesting
[21:03] <eroomde> or something that matters
[21:04] <Randomskk> god forbid.
[21:04] <Randomskk> DanielRichman: is that right? is half plausible?
[21:04] <Randomskk> the more I learn about stats the more I realise I am always wrong when I use stats
[21:04] <DanielRichman> well yeah I only pretend to know what I'm doing
[21:04] <Randomskk> it's okay, that works for me actually in jobs and stuff too
[21:04] <Randomskk> "the... correlation is high. this is good."
[21:04] <DanielRichman> assuming 0.2% is true, P(300 balloons don't land on roads) = 0.54
[21:05] <Randomskk> oh I guess that's fine actually yes
[21:05] <Randomskk> but at the same time
[21:05] <Randomskk> 50/50 odds...
[21:05] <eroomde> the next one will be even more likely to land in a road then
[21:05] <eroomde> see, i understand stats
[21:05] <Randomskk> obviously
[21:05] <eroomde> i have a masters in it
[21:05] <Randomskk> I'm more interested in how likely it is that the rate is 0.2% given that 300 haven't
[21:06] <jonsowman> some of this aeriel footage of cambridge is really pretty
[21:06] <Randomskk> but I guess hurrah bayes
[21:06] Action: Randomskk guesses at priors, this is how it works right
[21:06] <DanielRichman> well, P(rate is 0.2%) = 0
[21:07] <DanielRichman> I can tell you that
[21:07] <DanielRichman> won't you have to have something like P(actual rate is within x% of 0.2%) ?
[21:08] <Randomskk> depends what you're trying to do
[21:08] <Randomskk> e.g. you could set up a null hypothesis and find the liklihood?
[21:08] <upix> when is the funny video coming up?
[21:09] <Randomskk> nearly done copying it from my laptop to my media tank
[21:09] <Randomskk> then I'll cut it and upload to youtube
[21:09] <Randomskk> not so long.
[21:09] <DanielRichman> Randomskk: i have no idea about that; but the point I was making was, supposing you did that and have a way of working out P(rate = X), X is gonna be some sort of continuous thing
[21:09] <Randomskk> well yea
[21:09] <DanielRichman> P(rate = 0.2) is area between 0.2 and 0.2
[21:10] <Randomskk> this is where the difference between PDFs and CDFs and so forth usually makes me sad, but

[21:14] <eroomde> when i was still at work
[21:14] <upix> oh
[21:15] <eroomde> but wanted to work it this weekend (it's a fast core i7 with lots of ram, my home machine is an 11" macbook air that chokes at what i'm working on atm)
[21:15] <Randomskk> eroomde: haha yea I now just leave my work computer on all the time
[21:15] <Randomskk> in case
[21:15] <eroomde> indeed. i don't know why I didn't
[21:15] <eroomde> i think it's because i did the friday clean-desk thing
[21:16] <eroomde> and turning pc off added to the organised stillness
[21:17] <Randomskk> mm
[21:18] <Upu> evening, love the image jonsowman
[21:20] <upix> eroomde: what exactly are you working on?
[21:20] <upix> just of curiosity
[21:21] <upix> if thats not a secret of course
[21:21] <eroomde> the pc stuff was to do with gps
[21:21] <eroomde> trying to make a software gps receiver
[21:21] <eroomde> that does sensor fusion with inertial sensors like accelerometers and gyroscopes
[21:21] <Randomskk> hmm ugh just remembered that this is the video with the product in
[21:21] <Randomskk> sigh
[21:21] <eroomde> to give good position fixes for really dynamic thing
[21:21] <jonsowman> ta upix
[21:21] <jonsowman> there's some excellent imagery
[21:21] <Randomskk> jonsowman: are you able to cut and upload a part from one of your videos? should have the same stuff
[21:22] <jonsowman> can do
[21:22] <Randomskk> for reference you can cut a time part of the video using mencoder
[21:22] <eroomde> upix: additionally, gps sats send a ping 1000 times a second
[21:22] <eroomde> so in theory you can get 1000hz position updates from gps
[21:23] <Randomskk> mencoder video.mp4 -ss 12:34 -endpos 14:00 -ovc copy -oac pcm -o output.mp4
[21:23] <Randomskk> where 12:34 is start time and 14:00 is end time for instance
[21:24] <jonsowman> okay, will go on desktop in a min
[21:25] <eroomde> mencoder has always amused me as a word
[21:25] <eroomde> i can just imagine the pitch
[21:25] <Randomskk> its stupid command line options usually blind me to the stupid name
[21:25] <Randomskk> could be worse, could be ffmpeg.
[21:25] <eroomde> it's not your mum's video encoder, IT'S FOR MEN
[21:26] <upix> eroomde: doesn't the GPS receiver average and give you more precise position update but at slower rate?
[21:26] <eroomde> Randomskk: yes i must say that on the few occassions ive used mencoder it's been mostly google-found incantations
[21:26] <Laurenceb_> eroomde: openpilot have a nice kalman filter
[21:27] <eroomde> Laurenceb_: kalman doesn;t work
[21:27] <eroomde> upix: if you are standing still, then taking 1000 gps samples and averaging them will give you probably a good estimate of your position
[21:27] <eroomde> but that's it
[21:27] <eroomde> if you're moving, you can do way way better

[21:28] <Laurenceb_> extended kalman filter
[21:28] <eroomde> yes, but an ekf is not a kf
[21:29] <Laurenceb_> oh god
[21:29] <eroomde> and regardless, ekf is a horrible bodge
[21:29] <Laurenceb_> pedantry
[21:29] <upix> jonsowman: what imagery?
[21:29] <eroomde> it's what someone who has never heard of particle filters would design
[21:29] <jonsowman> upix: from the cameras today
[21:29] <upix> want to share?
[21:29] <Laurenceb_> heh indeed
[21:29] <jonsowman> we'll get it online soon, it's lots and lots of HD video, most of which is boring
[21:29] <jonsowman> like, about 40GB of it
[21:29] <Laurenceb_> particle filters are nice
[21:29] <eroomde> and regardless*2, when you have all the info offline then there's no need to sequential
[21:29] <eroomde> just general mcmc stuff is better
[21:30] <upix> it's midnight over here and my gf is nagging me go to sleep :D so I'm very impatient
[21:30] <Laurenceb_> "sleep"
[21:30] <jonsowman> upix: it'll be a few days
[21:30] <jonsowman> we couldn't fit it all on one laptop
[21:30] <eroomde> infact the guy who invented the unscented kalman filter named it so because he thought all other kalman filter implementations stink
[21:30] <jonsowman> so it's a bit spread out at the moment
[21:31] <Laurenceb_> someone has unscented working on F4
[21:31] <Laurenceb_> but no code :(
[21:31] <Randomskk> eroomde: at one point I had visions of putting a small media/file server in the cusf lab
[21:31] <eroomde> well F4 has a turing complete instruction set so that's sort of not remarkable
[21:31] <Randomskk> to store all the media
[21:32] <Randomskk> but frankly it'l never happen
[21:32] <eroomde> Randomskk: just spend the monies
[21:32] <Randomskk> so maybe our best bet would be to pay for vimeo as well as flickr, then fill both with all the stuff, private where required
[21:32] <eroomde> get a synology
[21:32] <eroomde> invest no time in setup
[21:32] <Randomskk> plus that way it's all online and backed up.
[21:32] <eroomde> dump stuff onto it
[21:32] <Randomskk> considered that
[21:32] <upix> jonsowman: so I should wait now?
[21:33] <upix> or not
[21:33] <jonsowman> upix: no, nothing interesting today really, apart from potentially the thing that Randomskk is uploading
[21:33] <Randomskk> not uploading
[21:33] <upix> ya I wanna see that

[21:33] <jonsowman> we'll tweet when stuff's online
[21:33] <upix> is that tweet?
[21:33] <jonsowman> yes
[21:34] <jonsowman> we might email a compilation to the ukhas list
[21:34] <Randomskk> eroomde: I guess we could also do both.
[21:34] <Randomskk> maybe a drobo :p
[21:34] <jonsowman> if that's not considered too spammy

[22:19] <LazyLeopard> 120810 22:33:56 271 22:39:07* 334 81 22:44:33* 91
[22:20] <LazyLeopard> date rise-time bearing max-time bearing elevation set time bearing, and * indicates in eclipse.
[22:20] <eroomde> I see
[22:20] <eroomde> might try and catch it then
[22:20] <LazyLeopard> I'm sure heavensabove will give something more informative, though.

[22:24] <stilldavid> thanks natrium42 !
[22:24] <stilldavid> I wish we had better results, that was a pretty slick radio module we took up
[22:25] <stilldavid> but turns out the ground station was listening at 950MHz instead of 915... simple human error :\
[22:25] <Lunar_Lander> hi natrium42
[22:25] <Lunar_Lander> do you mean the thing about Pike's Peak on sparkfun?

[23:02] <r2x0t> habhub predict not working again... good only for 2 days, after that it returns nothing (but downloads GFS data OK)
[23:03] <r2x0t> result looks like http://habhub.org/predict/#!/uuid=b6bdca67b06bcb7a73c5630c56c22e95ed6b8227
[23:07] <natrium42> "Exception: Unhandled exception: ServerError: 'Server error 0: "/gfs/gfs20120810/gfs_18z is not an available dataset""
[23:08] <r2x0t> hm
[23:08] <natrium42> i think it's being fixed
[23:08] <r2x0t> but it said it downloaded something
[23:10] <r2x0t> tried another
[23:10] <r2x0t> http://habhub.org/predict/#!/uuid=c66fc9e320d89fa2e593962b3584eb9a90c12bd0
[23:11] <r2x0t> it downloaded GFS data, 10/25/....85% for about 30 seconds
[23:11] <r2x0t> but result is empty track
[23:11] <r2x0t> click on CSV export
[23:12] <r2x0t> ends at 8590m then LAT is -inf
[23:12] <r2x0t> and LON inf
[23:12] <r2x0t> looks like predictor computation problem to me
[23:13] <Lunar_Lander> good night

[23:30] <Randomskk> thanks for that eroomde
[23:30] <Randomskk> incidentally I get emails
[23:30] <Randomskk> no idea why that's happening
