[02:56] <manderson21> haha, BK @CAA:89?
[03:00] <natrium42> nickolai: da, konechno :P
[03:01] <nickolai> da, ya rodilsya v rossiye, no i davno uzhe v CShA
[03:01] <natrium42> where in usa?
[03:01] <nickolai> NJ
[03:01] <nickolai> you?
[03:01] <nickolai> o wait
[03:01] <nickolai> ur in canada right?
[03:01] <natrium42> i am in the bay area right now
[03:01] <nickolai> o nice
[03:02] <natrium42> interviewing, but yes, originally from ontario
[03:02] <nickolai> i've seen your website, it was one of the first few i found actually
[03:02] <natrium42> cool :)
[03:02] <manderson21> natrium is the one who told me to come here
[03:02] <manderson21> crazy Russians
[03:02] <nickolai> heh heh
[03:03] <nickolai> this is really a great spot
[03:03] <natrium42> nickolai: so you're planning to do your own launch?
[03:03] <nickolai> Dan-K2VOL directed me to hackerspaces and my life basically hasn't been the same since :)
[03:03] <natrium42> you got the bug :)
[03:03] <nickolai> actually yes, i;ve made a lot of progress and i'm targetting tuesday for launch
[03:04] <natrium42> ah, awesome
[03:04] <natrium42> what's on board?
[03:04] <nickolai> not much, chipkit board for the main computer, inventek GPS and ntx2 transmitter. A still cam and a flipcam for imagery
[03:04] <natrium42> manderson21: you should drop your UAV from a balloon
[03:04] <nickolai> if i can find some temp sensors at the hackerspace i'll throw those on
[03:05] <natrium42> cool
[03:05] <manderson21> from a balloon?
[03:05] <nickolai> i'm actually on because i was wondering about antennas for the payload
[03:05] <natrium42> non-aprs launches are more exciting imo :)
[03:05] <nickolai> what did you use natrium42?
[03:05] <manderson21> what's aprs?
[03:06] <natrium42> automatic packet reporting system
[03:06] <natrium42> nickolai: i haven't flown an ntx2 yet
[03:06] <manderson21> i.e. no GPS?
[03:06] <natrium42> people just use a 1/4 wave with ground radials
[03:06] <manderson21> I do have a telit GSM/GPS module sitting next to me :-)
[03:07] <natrium42> nono, APRS is a network of radios so that you can uplink your position from gps
[03:07] <nickolai> that's kind of what i was wondering, why a 1/4 wave?
[03:07] <nickolai> so u don't need to buy your own receiver for aprs?
[03:07] <natrium42> it's shorter than 1/2 wave i guess, and good enough :)
[03:08] <natrium42> no, for aprs you can just use the network
[03:08] <natrium42> but you need to be licensed
[03:08] <natrium42> as your payload would be a transmitteron ham frequencies
[03:08] <nickolai> ah, damn
[03:09] <natrium42> but you are using a ntx2, so you're fine
[03:09] <natrium42> do you have a radio to pick it up?
[03:09] <nickolai> yea someone at the hackerspace happens to have one they're lending to me
[03:09] <nickolai> but the thing is like 600 bucks
[03:10] <nickolai> i want to find a data solution that's cheaper, and doesn't require a license
[03:10] <natrium42> could use the xtend modules
[03:10] <manderson21> natrium42, I don't think I would be able to communicate with my quadcopter from a balloon drop
[03:10] <natrium42> 1/4 on the payload and yagi on the ground
[03:11] <manderson21> natrium42, unless it's supposed to navigate via GPS
[03:11] <nickolai> do u have any links on the xtend stuff?
[03:11] <nickolai> manderson21: what do you mean?
[03:11] Dan-K2VOL (~Dan-K2VOL@ left irc: Quit: Leaving.
[03:12] <natrium42> i believe wb8elk has flown one sucessfully
[03:12] <natrium42> he sometimes comes to this channel, or you could email him
[03:12] <natrium42> i have flown xtend too, but with an omni on the ground, so it went out of range
[03:12] <natrium42> the thing is that they are not that cheap
[03:13] <natrium42> the best option in north america is to get a ham license
[03:13] <natrium42> and some used radio from ebay
[03:15] <natrium42> nickolai: you could try searching ebay for Yaesu FT-790R or Yaesu FT-817(ND)
[03:15] <natrium42> they are nice radios to use with ntx2
[03:15] <nickolai> i have, they're expensive
[03:16] <nickolai> i'm looking at putting together a kit for the average joe to be able to buy and go launch a balloon, and so i can't really tell people to go find their receiver on ebay
[03:16] <natrium42> ah
[03:16] <nickolai> i also think asking them to get a ham radio license is a bit much
[03:16] <manderson21> nickolai, I mean travel through waypoints
[03:16] <natrium42> well, another option is SPOT or a cellphone
[03:17] <natrium42> spot is pretty cheap and reliable
[03:17] <nickolai> manderson21: so what issues would the antennas have? or were you talking about xtend?
[03:17] <natrium42> manderson21: http://www.hicam.com/pro_x2.htm
[03:18] <manderson21> I was referring to natrium42 telling me I should do a balloon drop with my quadcopter, but I don't know how I would control/communicate with it
[03:18] <natrium42> manderson21: xtend would work really well for this
[03:18] <natrium42> you get 9600 baud both ways
[03:19] <manderson21> how far?
[03:20] <natrium42> 40 miles
[03:20] <natrium42> http://www.digi.com/products/wireless-wired-embedded-solutions/zigbee-rf-modules/point-multipoint-rfmodules/xtend-module#overview
[03:20] <nickolai> natrium42: yea a cell phone is an option, but i figure it should have a radio as well
[03:20] <manderson21> sweet jesus
[03:21] <nickolai> since that part of the fun is chasing it, isn't it?
[03:21] <natrium42> yeah
[03:21] <manderson21> $229 for one
[03:22] <natrium42> manderson21: you can borrow mine :P
[03:22] <natrium42> but of course, you might lose them
[03:22] <manderson21> dude, the batteries won't last that long
[03:23] <manderson21> that reminds me, I was about to buy some cheapo $20 chopper on amazon :p
[03:23] <natrium42> manderson21: this canadian dude has dropped a guided glider from a balloon years ago http://members.shaw.ca/sonde/
[03:23] <manderson21> $179 for industrial grade
[03:23] <natrium42> induastrial grade is batter
[03:23] <nickolai> that's not too bad
[03:24] <natrium42> as it's rated for low temp
[03:24] <nickolai> what receivers are good for this one?
[03:24] <manderson21> natrium42, a glider isn't a quadcopter
[03:24] <natrium42> nickolai: you just use two xtend modules
[03:24] <natrium42> the one on balloon with a 1/4 wave, and the ground oone with a 900MHz yagi
[03:25] <nickolai> it looks like it's cheaper to buy a 900mhz receiver
[03:25] <nickolai> remember, this is for a kit so cost is critical
[03:25] <nickolai> it should be as cheap as possible
[03:25] <nickolai> without losing too many features....
[03:25] <manderson21> natrium42, are you suggesting I build a plane instead of a helicopter?
[03:26] <natrium42> nickolai: wb8elk also tested zigbee and had some success
[03:26] <nickolai> manderson21: what sort of project are you working on? do you have any description of it somewhere?
[03:26] <natrium42> but it went out of range
[03:26] <nickolai> i'll take a look at that
[03:26] <manderson21> nickolai, no description, I just want to build a quadcopter :p
[03:26] <nickolai> and work with it at high altitudes?
[03:26] <natrium42> i have been thinking of dropping a gyrocopter
[03:27] <manderson21> at first, I wanted it to carry my dslr for video/pictures, but there's no way that'll happen without spending a lot of money on batteries and the motors to carry the load
[03:27] <manderson21> now, I'm thinking of doing something with a video stream
[03:29] <nickolai> that would be cool
[03:29] <manderson21> yeah, so it's something that would be pretty short range
[03:29] niftylettuce (u2733@gateway/web/irccloud.com/x-hydwkhfgxonevomk) left irc: Quit: Connection closed for inactivity
[03:29] <manderson21> like 100 ft radius
[03:31] <manderson21> long flight time would be awesome, but I'm not sure how much those batteries would cost
[03:31] <manderson21> natrium42, what's the link for your balloon?
[03:32] <natrium42> http://natrium42.com/halo
[03:32] <manderson21> nevermind, found it: http://www.natrium42.com/halo/flight2/
[03:33] <manderson21> natrium42, did it upload pictures while flying or did you grab them afterward?
[03:34] <natrium42> flight1 downlinked pictures in-flight via the xtend
[03:34] <natrium42> flight2 didn't
[03:35] <natrium42> http://ukhas.org.uk/projects:halo_flight1
[03:35] <nickolai> how long did it take for a picture to get through?
[03:35] <natrium42> a couple of seconds
[03:35] <natrium42> they were only thumbnails
[03:36] <manderson21> how did you get flight 2 to take video?
[03:37] <natrium42> oh, i just wired to the camera buttons and switched it between picture and video modes
[03:37] <natrium42> nowadays it's better to use a gopro hd camera
[03:38] <nickolai> i'm going to have a kodak zi8 on my flight
[03:38] <nickolai> it only lasts 1h30min on full charge tho, so i want to break into it and be able to turn it on after, say, 30 mins
[03:40] <natrium42> ah, cool
[03:47] <manderson21> natrium42, what would you have done if it had landed in the water? :(
[03:48] <natrium42> maybe it would have floated up eventually
[03:48] <natrium42> there's always plan b
[03:48] <manderson21> XD
[03:48] <nickolai> was it watertight?
[03:48] <natrium42> actually, juxta had his land in the ocean
[03:48] <nickolai> oh really?
[03:49] <natrium42> so he had to swim to retrieve it
[03:49] <nickolai> seriously?
[03:49] <natrium42> one sec, i will link you to pix
[03:49] <manderson21> O_O
[03:50] <manderson21> I would put a note inside with some money and say "please ship to this address"
[03:50] <manderson21> then again, I'm fairly lazy
[03:50] <natrium42> manderson21: http://projecthorus.org/?page_id=1497
[03:57] <manderson21> I'd be too afraid of making one and it landing in an amish farm, then asking them to let me retrieve it
[03:58] <manderson21> plus, I'm a rather shy person
[04:01] <natrium42> manderson21: "finders - keepers"
[04:01] <natrium42> "losers - weepers"
[04:02] <manderson21> :'(
[04:09] <nickolai> what's wrong with the thing landing in an amish farm?
[04:10] <natrium42> you have to ask for permission to retrieve it, any time it lands on private property
[04:11] <manderson21> nickolai, they might think I'm the devil (joking)
[04:11] <natrium42> or who knows, you might get shot in yankeeland
[04:11] <manderson21> I'm too shy
[04:12] <nickolai> i mean obviously with the asking and the private property, but are amish known to be hostile to us electronics-toting, balloon-flying outsiders?
[04:16] <manderson21> I see them in cars all the time around here
[04:16] <manderson21> I'm sure it's fine
[04:16] <nickolai> really?
[04:16] <nickolai> (to the cars thing)
[04:18] <manderson21> yeah, I used to see this doctor (he was pretty much a chiropractor), and he had lots of amish patients
[04:19] <nickolai> hm
[04:19] <manderson21> he also smelled like weed every time I saw him
[04:20] <manderson21> and prescribed sugar pills
[04:23] <nickolai> haha

[06:54] <daveake_> Morning :)
[06:57] <Elwell> so, who nicked HTV-2 then?
[07:00] <number10> I think they had problems receiving the telemetry from the NTX2 at those velocities
[07:01] <Elwell> someone should have told em the frequency drifts depending on temperature
[07:01] <SamSilver> Range assets have lost telemetry with HTV2.
[07:02] <Elwell> 'tea lady tripped over the antenna cable'
[07:02] <daveake_> Maybe an XML error in their tracker
[07:03] <Elwell> probably string v float errors in the 'duino code
[07:03] <fsphil> haha
[07:04] <number10> I saw some of the code and noticed a misplaced semicolon while(1);
[07:04] <fsphil> did they ever find it?
[07:05] <Elwell> fsphil: dunno, but I bet the chinese are sending people to help look right now :-)
[07:06] <fsphil> aah, that's nice of them ;)
[07:08] <daveake_> Is there a map showing their chase boats?
[07:09] <Elwell> spacenear.us "Consultancy services" could be onto a winner here
[07:10] <daveake_> Need some new icons. Boats; burning HTV-2 ...
[07:10] <fsphil> I tried drawing a boat icon once, turns out I'm not an artist! ;)

[07:12] <fsphil> oh very nice

[07:23] <eroomde> Darkside: what time are you starting tomorrow?
[07:23] <Darkside> 7pm is when the talk is scheduled
[07:24] <Upu> hey daveake
[07:24] <Darkside> i'm going to be in the space a while before that though
[07:24] <Upu> Your payload is Cloud1 ?
[07:24] <daveake_> Yes ....
[07:24] <eroomde> Darkside: i mean LSM
[07:25] <Darkside> lsm?
[07:25] <daveake_> .... are you culling payloads? ;)
[07:25] <Darkside> ohhhh
[07:25] <Upu> daveake still considered active ?
[07:25] <Upu> yes I am the slayer of payloads
[07:25] <Upu> phear me
[07:25] <Darkside> eroomde: well i'm supposedlt arriving into london atound 9:14
[07:25] <daveake_> lol
[07:25] <eroomde> Darkside: wow early start
[07:25] <Darkside> and the museum doesn't open until 10am
[07:25] <eroomde> i'm out tonight
[07:25] <eroomde> so that might be a push for me
[07:25] <eroomde> but cool, i might come along midmorning too
[07:25] <eroomde> and meet up
[07:26] <Darkside> yeah i won't get getting into the museum until 10am
[07:26] <Upu> I put you back
[07:26] <daveake_> cloud1 is retired, but maybe you could rename it to be cloud2?
[07:26] <fsphil> or just cloud?
[07:26] <Darkside> i'll probably grab breakfast at the paddington train station, then learn how to use the tube system and get to the museum
[07:26] <daveake_> I don't mind :-)
[07:26] <Upu> done
[07:26] <fsphil> don't let numbers hold you back :)
[07:26] <Darkside> eroomde: can you use IRC mobile
[07:26] <daveake_> TVM
[07:26] <daveake_> lol
[07:26] <eroomde> Darkside: i can
[07:26] <Darkside> cool
[07:27] <eroomde> but there is also an old technology called phoning
[07:27] <Darkside> i'll be sure to check IRC throughout the morning
[07:27] <Darkside> haha
[07:27] <Darkside> but, but.. IRC!
[07:27] <eroomde> that some people use to coordinate meetspace interaction
[07:27] <daveake_> Actually I'm not sure if the next one will be cloud2 (fixed version of cloud1) or buzz1 (pico payload)
[07:27] <eroomde> (sarky in mornings - not had first coffee yet)
[07:27] <Upu> well let us know and we can set up the approriate xml
[07:27] <Upu> spelling
[07:27] <Upu> I need coffee too
[07:28] <daveake_> Will do
[07:28] <Darkside> ok ok... my number is +447709595872
[07:28] <daveake_> :)
[07:28] <daveake_> Ordered some balloons last night
[07:28] <fsphil> prank call time
[07:28] <daveake_> lol
[07:28] <Darkside> whee
[07:29] <Darkside> i'm waiting fsphil ...
[07:29] <number10> using those 36" ones that nige used for your buzz1 daveake?
[07:29] <fsphil> it'll happen when you least expect it Darkside. muhahaa
[07:29] <Darkside> aww
[07:29] <daveake_> No, a latex balloon to see how high it'll go without much weight
[07:29] <eroomde> Darkside: can you pm me your phone no?
[07:30] <Darkside> my number is +447709595872
[07:30] <daveake_> Part of the payload will be a model Buzz Lightyear. At 7g he'll be about 7% of the total!
[07:30] <daveake_> The payload will be shaped like a UFO, for a laugh
[07:30] <Upu> haha
[07:30] <number10> any pics?
[07:31] <daveake_> Not till I start building it!
[07:31] <number10> are you putting one of those 808 cameras ion board
[07:31] <fsphil> oooh flashy coloured LEDs?
[07:31] <eroomde> Darkside: ta
[07:32] <daveake_> Little camera - yes
[07:32] <eroomde> erm, i don't want to put 'darkside' in my phone
[07:32] <daveake_> LED - maybe :)
[07:32] <eroomde> cos i'm not in diehard 4
[07:32] <daveake_> Buzz after his maiden flight in cloud1 - http://www.daveakerman.com/wp-content/uploads/2011/07/P1020997-768x1024.jpg
[07:32] <fsphil> we should make a payload shaped like the HTV-2
[07:32] <Darkside> eroomde: Mark Jessop
[07:32] <eroomde> ta
[07:33] <daveake_> I really wanted to do an Apollo capsule for cloud1, but didn't have the time
[07:33] <eroomde> Darkside: texted you to check
[07:34] <number10> is that cider you have Buzz drinking?
[07:34] <Darkside> eroomde: got it
[07:34] <daveake_> Champagne for the helpers :)
[07:35] <daveake_> Those "glasses" are small ... Buzz is only about 3cm tall
[07:36] <fsphil> I hope the guys helping me next time are not here... they might be expecting Champagne!
[07:37] <eroomde> we have an emergency bottle of champagne in the boot during chases
[07:37] <eroomde> tactical landowner placation
[07:37] <fsphil> sheesh, this should be in the to-do list :)
[07:37] <eroomde> usually don't need to deploy it but occassionally it helps
[07:37] <Darkside> hahah
[07:37] <Darkside> we've never required it
[07:37] <eroomde> we did once
[07:37] <number10> good idea eroomde
[07:37] <eroomde> ukhas 1 launch for whoever remembers that
[07:38] <number10> can you land the next one in my garden please
[07:38] <eroomde> :)
[07:38] <Darkside> targeted landings would be good fun
[07:38] <daveake_> 3 essentials for after the payload is recovered - 1-champagne, 2-glasses, 3-bag to hold the stinking remains of the latex balloon
[07:39] <Darkside> drop the balloon when the predicted landing site falls within a certain area
[07:39] <eroomde> daveake_: number 3 is often overlloked and a good point

[07:39] <daveake_> I was amazed how bad it was. Good job there happened to be a bag in the boot!
[07:39] <Darkside> you get used to the smell
[07:39] <daveake_> hmmmm
[07:40] <fsphil> I solved that by landing in yorkshire
[07:40] <daveake_> lol
[07:40] <eroomde> usually for dawn launches you need a big hot breakfast
[07:40] <eroomde> in a thermos picnic bag
[07:40] <eroomde> everyone is cream crackered after an allnighter of hard work ands launching and chasing
[07:40] <eroomde> for nova 7 we had such an epic chase
[07:41] <eroomde> we just launched at 4am and started chasing and chasing and chasing, i was just going where the radio ops in the back told me
[07:41] <daveake_> Good thinking. We supplied bacon butties before the launch, and various snacks for after the recovery
[07:41] <eroomde> i got out my iphone to see where we were and it was like f*ing manchester
[07:41] <daveake_> lol

[07:41] <eroomde> a long long way from home
[07:41] <fsphil> oops
[07:42] <fsphil> did you get it back?
[07:42] <daveake_> We got lucky on that - 19 miles (25 by road) from home
[07:42] <eroomde> thankfully we had lots of coffee and hot sausages in the boot
[07:42] <eroomde> fsphil: yep
[07:42] <eroomde> the cameras failed
[07:42] <Darkside> eroomde: thats a long chase!
[07:42] <fsphil> ah man
[07:43] <eroomde> fsphil: this is all that came of nova 7

[07:43] <Darkside> almost beats soe of ours :P
[07:43] <Darkside> some*
[07:43] <eroomde> but we tried to get dawn again 2 weeks later
[07:43] <eroomde> http://www.nivnac.co.uk/files/HAPSD_NOVA8/HAPS-D_pan1_quarter.jpg
[07:43] <daveake_> I was thinking of a dawn launch for cloud2
[07:44] <Darkside> eroomde: oooooooooo
[07:44] <Darkside> pretty
[07:44] <daveake_> That's such a good picture
[07:44] <fsphil> I could never do a dawn launch-- I'm so not a morning person
[07:44] <daveake_> I am. Mrs Dave isn't.
[07:44] <fsphil> a 11am launch is tricky enough :)
[07:44] <daveake_> This "36km limit" ... has anyone tried over-filling the balloon and venting gradually at altitude to stop it bursting?
[07:44] <fsphil> an*
[07:45] <eroomde> daveake_: yes
[07:45] <daveake_> and ...?
[07:45] <eroomde> it still went into a float
[07:45] <daveake_> damn
[07:45] <fsphil> I think it'll need something lighter than latex
[07:45] <eroomde> daveake_: i'm putting together a sensor package to go in the balloon neck
[07:45] <Darkside> don't you need an exponentially greater amount of gas to get higher?
[07:45] <eroomde> we're going to get to the bottom of what's causing this

[07:46] <eroomde> Darkside: it's more the instrumentation
[07:46] <daveake_> In theory you just need a big balloon, light payload, and just enough gas to rise, but obviously in practice something else is going on
[07:46] <Darkside> pressure sensor?
[07:46] Nick change: GW8RAK_ -> GW8RAK
[07:46] <eroomde> needs sensitive differential and absolute pressures
[07:46] <Darkside> ahh
[07:46] <daveake_> very sensitive
[07:46] <eroomde> well, i *think* that's what we need to prove or disprove a few of the hypotheses

[07:48] <eroomde> this is how i spend my 3ams
[07:49] <eroomde> in shorts
[07:49] <fsphil> better than the way a lot of people spend 3am
[07:49] <eroomde> because it's fine to touch them
[07:49] <eroomde> also i am holding the fill rig
[07:49] <eroomde> iain is touching the balloon
[07:49] <Darkside> heh
[07:49] <Darkside> doesn't it damage them?
[07:49] <Darkside> and make them burst earlier
[07:50] <eroomde> i think it makes v little difference compared to everything else
[07:50] <eroomde> like manufacturing defects
[07:50] <eroomde> or age
[07:50] <Darkside> ah ok
[07:50] <eroomde> or UV
[07:50] <daveake_> We used latex gloves. The first few gloves broke immediately which just shows how old the box is

[07:52] <daveake_> Didn't even know it was a race till the start gun went off!
[07:52] <fsphil> you thought it was pirates?
[07:52] <daveake_> I thought it was a gentle sail around the harbour!
[07:52] <fsphil> I hope someone else launches in NI soon, I'd like to attend a launch and not be in a panic getting everything ready

[07:53] <daveake_> I want to help track. Only tried once (aside from my own launch) and didn't get even one complete packet
[07:54] <fsphil> I had similar success the first time
[07:54] <number10> is there a lanch from EARS around the 20th
[07:55] <Upu> the two balloons we launched for James May were "fingered"
[07:55] <Upu> James was shouted at for touching them without gloves
[07:55] <number10> hey Upu how come canary was called that and then changed to budgie
[07:55] <fsphil> we don't use gloves, though I try to keep hands away from it. if it's windy it's difficult though
[07:56] WillDuckworth (51ab8387@gateway/web/freenode/ip. left irc: Client Quit
[07:56] <Upu> HI number10, complex but basically the TV company wanted it to be called Budgie
[07:56] <Upu> and Rob had called it Canary
[07:57] <Upu> which resulted in some last minute code hacking to fix as we didn't have the ability to program the payload on site
[07:57] WillDuckworth (c2498332@gateway/web/freenode/ip. joined #highaltitude.
[07:59] <WillDuckworth> just a quick one- think my payload XMLs have disappeared... anyone able to check?
[07:59] <WillDuckworth> wdhab and wdhabmini
[07:59] <Upu> yeah sure
[07:59] <Upu> I'll fix
[08:00] <fsphil> ah, that explains them Upu :)
[08:00] <WillDuckworth> cheers ;)
[08:00] <Upu> fixed WillDuckworth sorry we did some clearning up
[08:00] <WillDuckworth> thought they'd gone walkabout
[08:00] <Upu> well by we I mean I
[08:00] <fsphil> Upu-- would it help to put some <!-- comments --> into the xml to help identify them?
[08:00] <Upu> yeah would be great so we know who owns what
[08:00] <Upu> just refresh payloads WillDuckworth
[08:00] <fsphil> or even a proper xml field
[08:01] <Upu> I'll speak to Randomskk about it this evening
[08:01] <daveake_> good idea
[08:01] <WillDuckworth> excellent - cheers Upu, can you tweak wdhabmini to be 425 shift and the callsign set to WDHABmini - good idea with an <owner> type tag
[08:01] <fsphil> could have a comment or title field, even display the info in dl-fldigi
[08:02] <daveake_> How do chase cars get added?
[08:02] <Upu> done WillDuckworth
[08:03] <Upu> daveake_ http://ukhas.org.uk/general:chase_car_trackers
[08:03] <WillDuckworth> excellent - i'm nearly ready to roll :)
[08:03] <Upu> also dl-fldigi has the ability to do it with a local GPS but I'm not sure how to get that working
[08:03] <fsphil> just select the gps serial device, it should 'just work'
[08:04] <fsphil> though I think there's an issue with certain gps devices that rocketboy found
[08:04] <Upu> haha
[08:04] <daveake_> The latter was what was thinking of - I have a USB GPS for my netbook.
[08:04] <fsphil> worked on mine :)
[08:04] <daveake_> That said, I have an Android so I can try that one too

[08:04] <Upu> something like that ?
[08:04] <WillDuckworth> good stuff daveake_ let me know how you go with it ;)
[08:05] <daveake_> Upu that's the one I have
[08:05] <daveake_> WillDuckworth will do :)
[08:05] <fsphil> ooh snap
[08:05] <Upu> oh let me know if it works
[08:05] <fsphil> I think that'll work fine
[08:05] <fsphil> had it on the dashboard, kept sliding off

[09:26] <edmoore> did you see my email?
[09:26] <rjharrison> oh not yet
[09:26] <rjharrison> Yep
[09:26] <edmoore> i think it would be better if we could just display what is local to a predicted trajectory
[09:26] <rjharrison> edmoore, plan to filter on launch, land and path
[09:26] <edmoore> and at the time of the forecast
[09:27] <edmoore> cool yep
[09:27] <rjharrison> That was just a first step to see if it was possible
[09:27] <rjharrison> The restrictions are usefull too not just the NOTAMS
[09:28] <DanielRichman> that's cool. Is it more compilicated than a daily cronjob to mirror the file?
[09:28] <rjharrison> no its only 167k
[09:30] <rjharrison> I'm hoping to get the DB though as it will make parsing for paths / locations easier for a given launch window
[09:30] <edmoore> we'll need to implement a atmospheric data cache too

[09:30] <edmoore> it should take 1s really to do a pred
[09:31] <edmoore> it used to back in the day
[09:31] <DanielRichman> the predictor does cache data
[09:31] <DanielRichman> it just doesn't preload it
[09:31] <edmoore> well fine. the effect is the same
[09:31] <edmoore> it takes too long
[09:32] <DanielRichman> we could look through predictions in the past and preload data for common places
[09:32] <edmoore> i think it should just grab all of the uk when the new models come out
[09:32] <edmoore> the 00Z, 06Z, 12Z etc
[09:32] <DanielRichman> haha, fair enough
[09:33] <rjharrison> Given that my coding skills are being superceeded these days shall I take on the job of rolling the NOTAMS into HABHUB pred. With some toggel options?
[09:33] <edmoore> yeah - maybe something that can take a predictor output and construct a notmal kml from it
[09:33] <edmoore> notam*
[09:34] <edmoore> notam/restricted/whatever
[09:34] <rjharrison> Yep the other stuff basically
[09:34] <rjharrison> is pred output kml?
[09:34] <edmoore> maybe a huristic to stop it going 'alert! you are launching from a notam zone!' which of course has to be the case
[09:35] <SpeedEvil> Don't NOTAMS have a floor altitude?
[09:35] <SpeedEvil> Which may not be the ground.
[09:35] <rjharrison> Yep I don't plan to issue wanings just show the notams inforce around launch land and path +- a bi
[09:35] <rjharrison> t

[09:40] <SpeedEvil> I have the UK covered in exclamation marks.
[09:40] <rjharrison> Yep if you zoom right in it's better
[09:40] <fsphil> can probably shrink the icon when zoomed out

[10:46] <fsphil> There's hope for my "Remote control operation lessons" then!
[10:46] <cuddykid> lol
[10:47] <daveake_> How about lessons on "How to set up a Canon to run an intervalometer script, with particular attention to switching off standby mode and not saving as RAW"?
[10:47] <fsphil> man, grammar on the internet is awful. next forum I setup it'll have a mandatory english test for registering
[10:47] Action: fsphil signs up to that course
[10:47] <daveake_> Me too :-)
[10:48] <daveake_> Got it right once, then forgot when it came to doing it for the second time ...
[10:48] <fsphil> the raw thing annoyed me for ages
[10:48] <daveake_> Yep. Wasted some Lithiums on that one
[10:50] <cuddykid> oh, bloody hell& typical, out of office auto reply!
[10:50] <cuddykid> don't think he can afford to have time off!
[10:50] <daveake_> lol
[10:51] <cuddykid> don't think this notam will ever turn up!
[10:51] <daveake_> At least that means I don't have to try to get my application in today ... might as well leave it till next week now.
[10:51] <cuddykid> good job the predictions aren't very good.. and still have a fair amount of work to do on payload
[10:51] <cuddykid> yeah

[10:57] <daveake_> "toodle" ... :)
[10:57] <Laurenceb> interesting
[10:57] <cuddykid> wooo.. radios are working :D
[10:57] <Laurenceb> just reading saturn5 manual - imu runs at 25hz
[10:58] <daveake_> Need to get at least one of the payloads done first. Quite busy at the mo.
[10:58] <daveake_> 25Hz ... is that the cycle time reading all the sensors?
[10:59] <daveake_> Don't tell me it's the clock speed :)
[10:59] <Laurenceb> cycle time
[11:00] <Laurenceb> someone linked the pdf on here a few days ago
[11:00] <Laurenceb> its using a gimbal
[11:00] <Laurenceb> but the core guidance and control was digital
[11:03] <fsphil> cuddykid, don't be silly, the radios are not working. it's all in your head
[11:04] <cuddykid> lol
[11:04] <fsphil> uh-oh, looks like the talk I'm doing is two months earlier than expected
[11:05] <cuddykid> can someone explain the need for this line when storing characters in a string? -> inData[index] = '\0'; // Null terminate the string
[11:05] <fsphil> the null marks the end of the string
[11:06] <fsphil> when you append a character to a string, it over-writes the null - so that line probably adds a new one. difficult to tell without the context
[11:06] <cuddykid> ahh right, I'll leave it then! :)
[11:06] <fsphil> strings that are missing a null can cause "bad things"

[11:20] <cuddykid> basically - what I want to do is.. "if the string received is "hello" then turn led on" !
[11:23] <daveake_> You might want to check what strcmp does, for a start :)

[11:39] <cuddykid> http://pastebin.com/Ph35Xf5D
[11:40] <cuddykid> is there a way to start storing chars in string when the char received is "h" then stop when char received is "o" ?
[11:40] <fsphil> you might be better having some kind of clear character, like $
[11:40] <fsphil> clear the buffer on receipt of an $
[11:40] <fsphil> then send it $hello
[11:41] <cuddykid> good point, will try and implement :)
[11:41] codetiger (~codetiger@ joined #highaltitude.
[11:41] <daveake_> and echo those characters back to make sure your baud rate is right and the software uart is keeping up
[11:41] <fsphil> also solves your other problem of when your buffer fills up, it stops working
[11:41] <daveake_> inded
[11:41] <daveake_> (buffer full in "inded")
[11:42] <cuddykid> however, how would it know when to stop storing data, surely it would just keep looping and clearing every time it received "$"
[11:42] <fsphil> soon as your strcmp works
[11:43] <fsphil> the $ clears it, you send "hello" .. the buffer will only contain "hello" so your strcmp will find a match
[11:44] <cuddykid> fsphil, would the strcmp bit need to be in the while serial.available bit then?
[11:44] <NigelMoby> Eek softserial
[11:44] <cuddykid> lol
[11:44] <NigelMoby> Afternoon BTW :p
[11:44] <fsphil> cuddykid, would do no harm. re-testing the buffer without adding anything to it is harmless but wasteful
[11:45] <cuddykid> will do some messing about, thanks :)

[11:46] <NigelMoby> What country ?
[11:46] <codetiger> India
[11:47] <NigelMoby> Ooo great! Which part you in?
[11:47] <codetiger> @NigelMoby are you going to send me a link showing some Indians already did that... :)
[11:47] <codetiger> Chennai
[11:48] <NigelMoby> Lol nope. I can't think of an Indian launch offhand...
[11:49] <codetiger> I spend almost 30% in shipping cost
[11:49] <edmoore> ouch!
[11:49] <NigelMoby> Blimey
[11:50] <edmoore> 120,000ft would be very impressive
[11:50] <codetiger> And it took me 2 yrs to find the right place to buy these stuff.
[11:50] <codetiger> @edmoore Like everyone, I dream high :)
[11:51] <codetiger> Let me give you a summery: Am planning to keep my payload less than 2.5 kgs
[11:51] <fsphil> you use imperial measurements in India?
[11:51] <codetiger> and my balloon is 1600g from Hwoyee
[11:52] <edmoore> the record for the uk is currently held by cusf at 36206 m (118785 ft)
[11:52] <edmoore> codetiger: if you want to be going >36km, try and keep the payload even lighter
[11:52] <codetiger> @fsphil not always imperial
[11:52] <edmoore> maybe 1.5 total if possible
[11:53] <edmoore> but equally there are some interesting phenomena around 36km that mean that it's too simplistic to say 'if you want to go high as possible, make your payload as light as possible'
[11:53] <codetiger> 1.5 should be possible from what I've planned. But am yet to decide on the battery and Cameras. So will try to keep it to the best possible
[11:54] <edmoore> we (well, I at least) don't really know yet why some balloons go from ascending to floating at around 36km
[11:54] <edmoore> we have ideas, but no data to prove or disprove them yet
[11:55] <codetiger> Meanwhile how much should I fill the balloon. Some ppl say fill it less to let it expand more. And some ppl say they filled it very less and it came back soon.
[11:55] <edmoore> this is a question that we can't really answer yet
[11:55] <edmoore> because the cause of this floating is unknown
[11:55] <edmoore> in general: more gas = fast ascent and lower burst
[11:55] <edmoore> less gas = lower ascent and higher burst
[11:56] <codetiger> :) so does 1600g and 1000g ballons make any difference in height
[11:56] <edmoore> yes
[11:56] <edmoore> because a bigger balloon van get to a larger volume before bursting
[11:56] <edmoore> so, with everything else being equal, the gas inside can get to a lower pressure, which happens the higher you go
[11:58] <edmoore> *however*, we have found that very light payloads with not much gas inside big balloons often seem to stop at about 35/36km, when the calculations say they should carry on to 37 or 38km
[11:58] <edmoore> instead the slow down and start to floart
[11:58] <edmoore> float*
[11:58] <edmoore> this is very interesting and something that we need to investigate more
[11:59] <codetiger> Interesting information
[12:00] Jasperw (~jasperw@thingy.pointless.net) joined #highaltitude.
[12:00] <codetiger> So how do you guys fill. or meassure the balloon filling? You measure pressure?
[12:00] <codetiger> or the volume of the gas?
[12:00] <edmoore> we measure lift
[12:01] <edmoore> so, lets say we calculate that with our 1600g balloon and 1.5kg payload, we need 500g of 'free' lift
[12:01] <codetiger> oh so that makes it easy. Coz I was afraid if I should buy or rent some measuring device.
[12:01] <edmoore> so we need the pull at the neck of the balloon to be 1.5kg + 500g = 2kg
[12:01] <edmoore> so we put 2kg of stuff in a bag and hang it from a filler tube that is filling the balloon
[12:02] <edmoore> once the balloon can only just begin to lift this ballast bag, we know we have enough helium
[12:02] <daveake_> I just filled a cola bottle with water to the calculated weight, then tied that to the balloon neck temporarily and inflated till it was just held off the ground. Take the filler weight into account when you do that.
[12:02] <edmoore> once the balloon is tied, you need to seal it
[12:02] <daveake_> Helps
[12:02] <daveake_> :)
[12:03] <edmoore> here is a very good demonstration of a good way of doing that by RocketBoy: http://ukhas.org.uk/guides:sealing_the_balloon?s[]=balloon
[12:04] <daveake_> That looks pretty much like what I did, except I put the tape on the balloon neck first before any string or cable ties. I was paranoid about damaging the latex.
[12:05] <codetiger> @edmoore Thanks for the link. Good one. What else do I do to make it fly higher.
[12:05] <fsphil> tape might do more damage
[12:05] <edmoore> the necks are usually pretty robust
[12:05] <daveake_> ok
[12:05] <codetiger> 1) I fill it right
[12:06] <fsphil> although I always tape over the cable ties before launching
[12:06] <codetiger> 2) Keep payload at minimal weight
[12:06] <edmoore> codetiger: well, if you want to get above 36km then I can't help you - none of us have figured out what is causing the floating and how to beat it!
[12:06] <edmoore> but if you want to get to about 35, just got for a big balloon and a light payload
[12:06] <edmoore> aim for an ascent rate of about 3-4m/s
[12:06] <cuddykid> hmm.. still not getting anywhere :(
[12:06] <cuddykid> http://pastebin.com/FUpB7pTf
[12:06] <edmoore> that's all there is to it
[12:07] <edmoore> codetiger: there is a burst calculator built into habhub.org/predict
[12:07] <cuddykid> all I'm seeing on serial monitor is string building up then stopping at "$Hello"
[12:08] <fsphil> you'll need to set index to 0 when clearing the buffer
[12:08] <fsphil> you're storing the special characters too
[12:09] <fsphil> the logic should be, if asterisk, or if doller, else store
[12:09] <cuddykid> oh right :), so when if (inChar == '$') { index set to 0..
[12:09] <daveake_> Yes
[12:09] <cuddykid> as well as the memset stuff?
[12:09] <daveake_> And don't store it too!
[12:09] <daveake_> No need for the memset
[12:10] <fsphil> memset stuff is overkill, just set the first byte in the string to '\0'
[12:10] <cuddykid> I see, as it should write over it?
[12:10] <daveake_> Yes. Means you *must* do the '\0' bit and do that *before* the println
[12:11] <codetiger> @edmoore When I use the predicting tool. It shows me 29990m :(
[12:11] <daveake_> That's about right for 1.5kg load and 1.6kg balloon
[12:11] <codetiger> @edmoore what does Lat/Lon Deltas mean>
[12:12] <codetiger> Sorry the burst altitude is preentered
[12:14] <fsphil> deltas sets the area the predictor will download wind data for
[12:15] <fsphil> the default is enough to cover most flights
[12:19] <cuddykid> fsphil, could you have a brief look at new code if poss! sorry! - still not working lol - http://pastebin.com/w1GUjWL8
[12:19] <codetiger> Is the prediction too near to perfect? I mean atleast +/- 5kms ?
[12:19] <fsphil> two things
[12:20] <fsphil> index++; when resetting the buffer isn't needed
[12:20] <fsphil> the '\0' isn't counted
[12:20] <fsphil> and you're still storing the special characters in the buffer
[12:20] <fsphil> so your buffer actually contains $Hello* instead of just Hello
[12:20] <fsphil> the strcmp test will fail
[12:21] <edmoore> Randomskk: p[ing
[12:21] <edmoore> jonsowman: pang
[12:21] <cuddykid> ah right fsphil
[12:21] <cuddykid> thanks, will have another go!
[12:22] <fsphil> ain't C wonderful :D
[12:23] <cuddykid> fsphil, why isn't the '\0' counted? is it because inData[0] not inData[1] ?
[12:23] <cuddykid> lol, quite confusing!
[12:23] <fsphil> it just marks the end of the string
[12:23] <codetiger> @edmoore Is the prediction too accurate? I mean atleast +/- 5kms ?
[12:23] <cuddykid> fsphil, so I can just delete that?
[12:24] <fsphil> you can just remove the index++
[12:24] <cuddykid> got you
[12:24] <fsphil> with that there, the next character gets put after the '\0'
[12:24] <cuddykid> I see :D
[12:24] <fsphil> so you'll always end up with an empty string
[12:24] <cuddykid> yeah
[12:25] <cuddykid> how come the special chars are still being added? I thought by breaking the loop they would be avoided as it would move onto next char
[12:26] <fsphil> you might be right there
[12:26] <cuddykid> right, now on the serial monitor I'm getting mostly "Hello"
[12:26] <fsphil> misread the code
[12:26] <cuddykid> however, led is not coming on lol, I'm guessing it's stuck in the loop
[12:26] <cuddykid> yeah, no special chars being added now
[12:26] <fsphil> inData[index] = '\0' should be above the println
[12:28] <cuddykid> woo, printing out in serial monitor perfectly now&. however&. led still refusing to come on :(
[12:28] <fsphil> try printing something to the console instead of flashing the led
[12:29] <cuddykid> will do
[12:29] <cuddykid> all this debugging lol

[12:54] <Zuph> Just a block away from my University, though
[12:54] <NigeyS> blimey
[12:55] <NigeyS> did i see something about a whitestar launch this w/e ?
[12:55] <Zuph> Oh, not really a White Star launch
[12:55] <NigeyS> ahh just piggybacking ?
[12:55] <Zuph> Spaceport Indiana asked Dan to lead a latex flight. Some WB8ELK payloads, mostly.
[12:56] <edmoore> Randomskk: ok
[12:56] <NigeyS> oh cool
[12:56] <edmoore> sounds like an evening thing then
[12:56] <Zuph> We're going to fly some stuff too. See what happens to a BMP085 above its rated altitude.
[12:57] <NigeyS> Zuph, got ya, what they rated to btw ?

[12:58] <NigeyS> Two men accused of using Facebook to encourage riots, allegedly believed to be in Cardiff and Swansea, were remanded in custody by Cardiff magistrates.
[12:58] <NigeyS> meh
[12:58] <NigeyS> shoot them
[12:59] <Zuph> NigeyS: 300 hPa.
[12:59] <Zuph> We want to use it in the 200 hPa region. Have heard mixed reports of "working," but no one has handed out a data dump.
[13:00] <NigeyS> ah right, i think thats the same sensor darkside is sticking on to ats-1 on the 20th
[13:00] <NigeyS> outside the payload box with no insulation, should be err..fun
[13:00] <Zuph> heh
[13:01] <fsphil> "shoot them" .. and then if they find out they where actually innocent? oops

[13:09] <NigeyS> good point phil
[13:09] <daveake_> Question for any radio guys there .... on my HAB I made a ground plane from 4 bits of wire all the same length as the antenna itself (164mm IIRC). Does it make much/any difference if those ground plane wires are shorter? Is the rule "as large as possible" or is it "same length as antenna"?
[13:09] <Randomskk> "as large as possible"
[13:10] <Randomskk> negligable beyond about antenna length though
[13:10] <daveake_> Thanks, god :)
[13:10] <Elwell> ooooh gopro do a sync cable to get 3d with 2 cameras
[13:11] <Elwell> must... resist ... wallet .. urge
[13:11] <daveake_> Oh, and is a flat piece of ali foil as good as or better than the 4 wires?
[13:11] <NigeyS> Elwell, expensive ?
[13:11] <SamSilver> daveake_: you can affect the impedence by changing the angle
[13:11] <Elwell> 2* gopros and another 99 usd
[13:11] <Elwell> then the 3D tv to view it on I guess :)
[13:11] <NigeyS> eek, thats a good $700 ? ish
[13:11] <Randomskk> daveake_: about as good as. you basically wont' notice a difference.
[13:11] <daveake_> Ta
[13:12] <daveake_> SamSilver - angle them down, you mean?
[13:12] <Elwell> http://gopro.com/hd-hero-accessories/3d-hero-system/
[13:12] <Randomskk> ideally the wires should be at like 45 degrees upwards from the horizontal, so it looks like >- from the side, but in practice meh
[13:12] <daveake_> Ah
[13:12] <daveake_> OK
[13:12] <SamSilver> yes daveake_
[13:13] <fsphil> I had them flat, and people in london received the signal
[13:13] <daveake_> This is for my pico payload. I'm trying to make sure the radio part is OK, whilst wanting to make the whole thing look like a flying saucer :)
[13:13] <BrainDamage> add some led strobe please
[13:14] <daveake_> Ground plane wires coming down at an angle could look like legs, you see :)

[13:29] <fsphil> yep, exactly the same style
[13:29] <fsphil> they work very well
[13:29] <jcoxon> its worth it though
[13:29] <jcoxon> untangling the braid
[13:29] <jcoxon> my stronger antennas then soldering on wire

[13:41] <edmoore> edmoore
[13:42] <Darkside> edmoore: how much wil cusf charge for helium
[13:42] <edmoore> we don't give helium to anyone else
[13:42] <edmoore> period
[13:43] <edmoore> liability is bonkers
[13:43] <Darkside> np
[13:44] <Darkside> local boc?
[13:44] <Darkside> how much would they charge
[13:45] <edmoore> non idea
[13:46] <edmoore> our tanks would be £150/ea
[13:46] <Darkside> damn ok
[13:46] <Darkside> mm
[13:46] <Darkside> we'd only need a small amount
[13:46] <Darkside> 600g balloon
[13:46] <NigeyS> 1.8m^3 ish
[13:47] <Darkside> yeah
[13:47] <Darkside> if it ends up only being mininut flying...
[13:47] <Darkside> hell, we could underfull it
[13:47] <Darkside> underfill*
[13:48] <RocketBoy> A boc PT10 will give you 1.8
[13:48] <RocketBoy> or an air products N10
[13:48] <RocketBoy> gives about 2.6
[13:48] <NigeyS> yup, thats what i have here, the n10
[13:48] <Darkside> total cost?
[13:49] <daveake_> I used these guys = http://balloonhelium.co.uk/main/pricing
[13:49] <Darkside> i presume you pay a deposit on the bottle?
[13:49] <Darkside> ok, o you could get a 1.8m^3 bottle
[13:50] <RocketBoy> yeah - but what if you need slightly more on the day
[13:50] <daveake_> They deliver or you can collect from the local Air Products site
[13:50] <Darkside> RocketBoy: then i'd get a 2.6m^3
[13:51] <RocketBoy> probably best
[13:51] <Darkside> ill they refund if you return it part full?
[13:51] <daveake_> My lot didn't
[13:51] <Darkside> hrmm
[13:51] <Darkside> edmoore: know if anyone around cambridge way does that?
[13:51] <RocketBoy> £36 delivery ouch
[13:51] <edmoore> Darkside: honestly don't know
[13:52] <edmoore> infact there's a balloon party shop we have used
[13:52] <edmoore> on the high steet
[13:52] <daveake_> Yeah, I collected. They have a place in Didcot which isn't far from me
[13:52] <RocketBoy> party days its called
[13:53] <RocketBoy> (the one edmoore is talking about)
[13:53] <Randomskk> edmoore: haha jon got the summons and emailed back
[13:53] Action: RocketBoy wistfully thinks of the early days of UK HABing
[13:53] <Randomskk> he regrets that he cannot get on IRC at the moment as he is enjoying his holiday too much
[13:53] <Darkside> hmmmm
[13:53] <Randomskk> but I asked if he's still up for coming to london
[13:53] <Randomskk> will let you know
[13:53] <Darkside> edmoore: so, ultra light payload + 600g balloon
[13:54] <Darkside> whatcha think could be done with it?
[13:54] <edmoore> what sort of payload mass?
[13:54] <Darkside> 68g
[13:54] <Darkside> say 80g with parachute
[13:54] <Darkside> and some kidn of foamish thing around it
[13:55] <edmoore> zigbee range test
[13:55] <Darkside> eh?
[13:56] <edmoore> baby floater
[13:56] <Darkside> hmm
[13:56] <Darkside> well, mininut is 68g with 3 AAA batteries
[13:57] <Darkside> could you underinflate the balloon and go for altitude?
[13:57] <Darkside> what kind of altitude could you get out of a 600g balloon like that?
[13:57] <RocketBoy> depends on the ascent rate
[13:58] <edmoore> oh yes party days
[13:58] <edmoore> Darkside: probably not that much
[13:58] <Randomskk> terribly dangerous but it'd be kinda fun to make a balloon float at about 20m altitude and have it scan for wifi networks, talk over gsm, all that
[13:59] <cuddykid> hmm, do maplin sell those SMA connectors for pcb/breadboards?
[13:59] <Randomskk> did anyone see the UAV droid thign someone showed off at one of the recent security conferences? it had wifi, gsm, gps, loads of scanning, basically wardrones
[13:59] <cuddykid> had a look but can't find any
[13:59] <cuddykid> that sounds v cool Randomskk
[13:59] <Darkside> edmoore: burst calc says you could do 36km with a 2.62m/s ascent rate
[13:59] <Darkside> 0.79m^3 of cas
[13:59] <RocketBoy> cuddykid: try rapid electronocs
[13:59] <edmoore> pfff
[14:00] <edmoore> ok we can try it
[14:00] <cuddykid> cheers RocketBoy
[14:00] <edmoore> for shits
[14:00] <Darkside> edmoore: or 37km with 1.24m/s lol
[14:00] <edmoore> we flew a badgercub in a jiffy bag on a 3kg balloon once
[14:00] <Darkside> highest ever flight of a 600g balloon lol
[14:00] <Darkside> edmoore: wow
[14:00] <edmoore> it died unfortunately
[14:00] <Darkside> eek
[14:00] <edmoore> it had a few hours early been smashed into the ground
[14:01] <Darkside> haha
[14:01] <edmoore> just thought we'd chace it
[14:01] <edmoore> chance*
[14:01] <edmoore> after a day of tethered tests with a 3kg
[14:01] <Darkside> aaaanyway, could be fun to try and hit 36-37km with a tiny payload
[14:01] <edmoore> yeah ok
[14:01] <edmoore> is there pressure onboard?
[14:01] <Darkside> yep
[14:01] <edmoore> oh!
[14:01] <edmoore> oh right
[14:01] <edmoore> now you're talking
[14:01] <edmoore> ok
[14:01] <Darkside> its a BMP085
[14:01] <edmoore> lets try and get it to float
[14:02] <Darkside> dunno how accurate it is at those altitudes then
[14:02] <Darkside> edmoore: >_>
[14:02] <Darkside> i want my payload back
[14:02] <Darkside> grr
[14:02] <edmoore> no way
[14:02] <NigeyS> lols
[14:03] <Darkside> if it floats, i'm not going to get it back am i
[14:03] <edmoore> we gotta float this thing...
[14:03] <edmoore> ok Darkside
[14:03] <edmoore> tell you what we just do as you said
[14:03] <edmoore> aim for 36km with 2ish m/s ascent
[14:03] <Darkside> jeez thats gonna be a SLOW launch
[14:03] <edmoore> pretend i ever said anything about floating
[14:03] <Darkside> time for a bbq in the middle
[14:03] <edmoore> cos i bet it'll just go up and pop
[14:03] Action: edmoore giggles
[14:03] <Darkside> edmoore: >_>
[14:04] <Darkside> so, what would be required to do a floader
[14:04] <Darkside> floater*
[14:04] <edmoore> nothing
[14:04] <edmoore> i think it will float anyway
[14:04] <Darkside> lets make the assumption i don't want teh payload back
[14:04] <Darkside> now what could we do
[14:04] <edmoore> i would go for nominal 37km
[14:04] <Darkside> lets say 100g payload, to allow for bigger batteries
[14:05] <edmoore> and make sure pressure is telemetered
[14:05] <Darkside> i know my mininut boards will run for 21 hours of 4x AA batteries
[14:05] <Darkside> but that'll make it heavier
[14:05] <SpeedEvil> I note that I have some 6*6" solar cells that output 4A@0.5V weighing 6g each
[14:06] <SpeedEvil> They are _very_ fragile though.
[14:06] <cuddykid> typical - go to do a range test and bam lead snaps off switch
[14:06] <cuddykid> the solar cells I have from solarbotics are great - over 8V at about 40mA in sun
[14:06] <Darkside> edmoore: okay
[14:07] <Darkside> i need to do a runtime test off 4x AAAs
[14:07] <Darkside> i'll do that tonight
[14:07] <cuddykid> I'm still using my lithiums that I flew on 1st flight - can't believe the amount of power in them!
[14:07] <fsphil> woo, home
[14:08] <edmoore> Darkside: is this for next sat?

[15:03] <NigeyS> oh SpeedEvil ATOS .. uve heard of them right ?
[15:06] <russss> everyone's painting that HTV crash as a failure but they weren't expecting to get it back in one piece

[15:10] <SpeedEvil> NigeyS: yes.
[15:10] <NigeyS> they got me in huge trouble this morning
[15:10] <NigeyS> reckoned i failed to attend
[15:10] <SpeedEvil> NigeyS: I'm currently completing an exciting 50 page form, with the aid of reading lots of underlying legislation.
[15:10] <SpeedEvil> And caselaw.
[15:10] <NigeyS> ouch
[15:11] <SpeedEvil> In the attempt to avoid getting called for a medical. Ow - what happened?
[15:11] <NigeyS> they seem to be awfully powerful for a health service body !
[15:11] <SpeedEvil> Yes.
[15:11] <NigeyS> they made an appointment, gave me wrong date, i got signed off
[15:11] <Laurenceb> whats up with a medical?
[15:11] <SpeedEvil> DWP decisionmakers are too often just rubberstamping the medical reports.
[15:11] <SpeedEvil> NigeyS: You have the actual letter?
[15:11] <SpeedEvil> Giving you the wrong date?
[15:12] <SpeedEvil> Laurenceb: Employment and Support Allowance.
[15:12] <NigeyS> i do, its been faxed to them this morning, i also have a letter they sent out 3 weeks later, giving me an appointment of the time / date they said i missed
[15:12] <SpeedEvil> Ah - they can reschedule.
[15:13] <NigeyS> yup, crafty sods
[15:13] <SpeedEvil> This is ESA?
[15:13] <NigeyS> yeah
[15:14] <SpeedEvil> You don't normally get paid after not attending a medical - you have to show 'good cause'.
[15:14] <NigeyS> well hopefully their own letter with the wrong date is good cause, if not im going to see a solicitor
[15:15] <SpeedEvil> It's one of the things to be hyper-paranoid about, as there are only a few causes spelled out in the legislation.
[15:15] <cuddykid> back from range test
[15:15] <SpeedEvil> http://www.dwp.gov.uk/publications/specialist-guides/decision-makers-guide/#vol8 are the handy docs you want.
[15:15] <NigeyS> SpeedEvil, dam :/
[15:15] <NigeyS> either way, their to powerful for a health service imo
[15:16] <NigeyS> cheers will have a long read !
[15:16] <cuddykid> radios performed as expected really - got about 700m out of them with ok los (few trees in the way) - however, dodgy antennas on both transmitter & received (just a chunk of coax)
[15:17] <SpeedEvil> http://www.dwp.gov.uk/docs/vol08.pdf - page 197
[15:17] <cuddykid> not exactly the 30 odd km I need but with improved antennas and 100% clear los then more range should be achieved hopefully :D
[15:17] <NigeyS> SpeedEvil, tnx, very helpful!!
[15:18] <SpeedEvil> In principle, your case is weak, if you had 7 days written notice of the examination.
[15:18] <cuddykid> NigeyS: with regards to cutdown - will upload photos & vid now
[15:19] <SpeedEvil> NigeyS: You probably want to be trying to reschedule for as soon as possible, to avoid losing payments.
[15:19] <SpeedEvil> NigeyS: rather than at this stage going through the route of complaints - you can do that later.
[15:19] <NigeyS> cuddykid, cheers :D

[15:20] <NigeyS> SpeedEvil, well, i filled in a form asking for reasons that i FTA, and spoke to DWp this morning asking on both occasions to be rescheduled
[15:20] <SpeedEvil> k
[15:20] <NigeyS> its gone back to the decision makers for re-examination apparently
[15:22] <SpeedEvil> But - 'If, ... they had 7 days notice ... the claimant cannot be treated as not having LCW' See 42245 on page 198
[15:22] <SpeedEvil> So a reconsideration is probably doomed to fail - and you need to get a new appointment ASAP.
[15:23] <cuddykid> going to alter the baud rate and shift on these modems - then test again
[15:23] <SpeedEvil> cuddykid: What modems are these?
[15:24] <NigeyS> SpeedEvil, hmm thats harsh, ill ring atos directly
[15:24] <cuddykid> SpeedEvil: easy radio advance ones
[15:24] <SpeedEvil> NigeyS: yes - failure to attend is nasty. Almost any other failure can be appealed and you get paid uering the ppeal.
[15:25] <SpeedEvil> NigeyS: Anway - have a read of the entire section. Gives a nice outline of what they should decide, and any possible escapes.
[15:26] <cuddykid> NigeyS: 3 photos at end of this set http://flic.kr/s/aHsjvtsTpK
[15:26] <NigeyS> tnx SpeedEvil will do :D
[15:26] <fsphil> cuddykid, that's pretty good range
[15:26] <fsphil> you sure it was actual data being transferred?
[15:26] <cuddykid> fsphil, yeah especially with effectively no antenna
[15:26] <cuddykid> yep
[15:27] <fsphil> oooh think what you could do with a bit of error correction too :)
[15:27] <cuddykid> as light went off in the dense area until it opened out for los (or almost)
[15:27] <cuddykid> I think it has error correction built in
[15:27] <fsphil> that's right, it's all handled by the modem
[15:27] <fsphil> excellent
[15:27] <cuddykid> not sure though, I'm just using their stuff - simply input serial then receive it the other end!
[15:28] <fsphil> are you flying this on a proper launch?
[15:28] <cuddykid> going to try it as uplink - just have whatever is received to be sent down via NTX2
[15:28] <cuddykid> yep, next one :)
[15:28] <fsphil> I'd be tempted to get a receiver here, see how far we can communicate with it
[15:28] <cuddykid> not sure if I will get over 10km out of it
[15:29] <cuddykid> going to change baud rate now and test again, see if it makes any noticeable difference
[15:29] <fsphil> got a 10-el yagi and a small mountain :)
[15:29] <fsphil> I wonder if they work 1:1 or can there be multiple receivers
[15:29] <fsphil> or something in an RX-only mode
[15:29] <cuddykid> might do! - however, I won't have receiver on ground for easyradio as I only have a transmitter and transceiver
[15:30] <cuddykid> and transceiver is going in the air
[15:30] <fsphil> aah
[15:30] <fsphil> so it's one-way
[15:30] <cuddykid> mine is yeah, but if successful will get another transceiver :)
[15:31] <fsphil> we could try to relay a message via it
[15:32] <cuddykid> yeah
[15:32] <cuddykid> thought not sure easy radios standard they use
[15:34] <fsphil> it would need to be the same hardware on all sides

[16:06] <fsphil> re
[16:06] <cuddykid> indeed stepping down the baud rate (but also shift) increased the range slightly :)
[16:06] <cuddykid> so will be transmitting at 2400 and 12.5khz shift
[16:06] <cuddykid> compared to 50 and 800mhz on the ntx2 lol
[16:07] <fsphil> 800mhz shift? :)
[16:07] <cuddykid> hz ;)
[16:07] <cuddykid> lol
[16:07] <fsphil> another Tim! :)
[16:07] <fsphil> the shift doesn't actually matter much in rtty
[16:07] <fsphil> at 50 baud you could have it as low as 25hz
[16:07] <cuddykid> oh right
[16:10] <fsphil> actually I think it can go lower, but the signal gets harder to decode
[16:11] <cuddykid> need to get the transmitter hooked up to my yagi at some point, should boost the range a bit :D
[16:11] <fsphil> definitely!
[16:11] <fsphil> so you went walkabout with the transceiver?
[16:11] <cuddykid> yup, well, bike!
[16:12] <fsphil> sweet
[16:12] <cuddykid> will build a 1/4 wave ground plane for transceiver

[16:16] <eroomde> you get twice the capacity, without any error-prone switching logic
[16:16] <SpeedEvil> Though there is extra fun if one develops an internal short
[16:17] <BrainDamage> make sure they have the same voltage before connecting in parallel :p

[20:48] <SpeedEvil> ako is it converted to decimal
[20:49] <SpeedEvil> ak.gif shows a scatter plot of two axes
[20:49] <SpeedEvil> without paying attention to sign.
[20:49] <Laurenceb_> oh nice
[20:49] <SpeedEvil> The resting points are clear.
[20:50] <SpeedEvil> And the errors seem to be quite consistently shaped
[20:50] <SpeedEvil> and fairly large
[20:51] jkominar (~justin@ left irc: Quit: It was a perfectly cromulent thing to do.
[20:51] <Laurenceb_> whats the sample rate?

[20:52] SelfishMan (~SelfishMa@ joined #highaltitude.
[20:52] <Laurenceb_> hmm similar to lsm
[20:52] <Laurenceb_> now what does my lsm noise look like...
[20:54] <SpeedEvil> splot [120:160] [150:190] [130:170] "ako" using 1:3:5
[20:55] <SpeedEvil> Round in one dimension, flatter in the third
[20:55] <SpeedEvil> hmm
[20:57] <Laurenceb_> yeah looks very similar noise
[20:58] <Laurenceb_> to lsm303dlh
[20:58] <Laurenceb_> looks roughly equivalent, only lsm has more bits
[20:58] <Laurenceb_> but noise is >> 1lsb at ~100hz so shrug

[21:05] <Laurenceb_> just about 30% more gain on lsm

[21:10] <Laurenceb_> presumably there is some worldmagmodel code in there?
[21:11] <SpeedEvil> I think that's raw
[21:11] <Laurenceb_> yeah i mean on the phone
[21:12] <SpeedEvil> There is a higher level daemon which mentions skipping calibration, so I assume that's where that happens
[21:12] <Laurenceb_> interesting
[21:12] <Laurenceb_> yeah id hope there would be mag model code in there
[21:12] Action: hibby drinks coffee from the bowl
[21:12] <Laurenceb_> ive got noaa worldmagmodel down to ~40KB on stm32
[21:13] <Laurenceb_> so its not like itd take up much space

[21:24] <SpeedEvil> Oh - there is a 'range' tweak - which I haven't looked at
[21:28] <Lunar_Lander> hi SpeedEvil GW8RAK
[21:28] <SpeedEvil> Taking 10 samples _really_ reduces the noise.
[21:28] <SpeedEvil> Averaging, that is
[21:31] <SpeedEvil> Most spots fall into a ball of about 1.5 samples in diameter, not 15
[21:33] <SpeedEvil> I suppose the sane question to ask is how it performs when you look at the accel and magno as one.
[21:33] <SpeedEvil> Which is something I'm not going into tonight.

[21:42] <RocketBoy> yo
[21:44] <Lunar_Lander> how's life?
[21:45] <RocketBoy> yeah fine - just upgrading the software on my flight controller at the moment
[21:46] <SpeedEvil> Laurenceb: Oooh!
[21:47] <SpeedEvil> splot "ak" binary format="%int16%int16%int16%*int16"
[21:48] <Lunar_Lander> that is nice
[21:49] <Lunar_Lander> RocketBoy : I'll probably get the Venus GPS soldered next week
[21:49] <Lunar_Lander> and as I read it, it can be handled though the TinyGPS library of Arduino
[21:50] <RocketBoy> are you going to interface via the SPi bus?
[21:56] <Laurenceb_> just a sec
[21:58] <Laurenceb_> nice - with lines is better
[21:59] <Laurenceb_> looks good and spherical
[22:00] <SpeedEvil> So it does.
[22:00] Action: SpeedEvil should try FFTing the raw data, but my FFTfu is weak.
[22:00] <Laurenceb_> use octave
[22:00] <RocketBoy> nights
[22:01] RocketBoy (steverand@5acfd4f7.bb.sky.com) left #highaltitude.
[22:01] <Laurenceb_> load using binary format... somehow
[22:01] <SpeedEvil> yeah - I need to learn octave.
[22:01] <Laurenceb_> plot(abs(fft(data)))
[22:01] <Laurenceb_> you need to load it first...
[22:05] <Laurenceb_> d=fopen('ak','r');
[22:05] <Laurenceb_> octave:3> a=fread(d,Inf,"int16",0);
[22:06] <Laurenceb_> works, but you need to split up the axes
[22:06] <SpeedEvil> Thanks - will get octave later, and have a play.
[22:06] <Lunar_Lander> http://www.youtube.com/watch?v=o6If6JgNQ-M&feature=related
[22:11] <Laurenceb_> done http://i.imgur.com/aNjsT.png
[22:11] <Laurenceb_> frequency on bottom axis, log amplitude on vertical
[22:11] <Laurenceb_> i picked a stationary region
[22:13] <Laurenceb_> thats in hz, assuming 100hz sampling
[22:17] <SpeedEvil> Oh - right. Delaying download to after midnight - quota reasons. :/
[22:17] <Laurenceb_> b=a(1:4:size(a)(1)); b=[b,a(2:4:size(a)(1))];b=[b,a(3:4:size(a)(1))];
[22:17] <SpeedEvil> So I guess not mains
[22:17] <Laurenceb_> then b is your data array
[22:17] <Laurenceb_> _very_ 1/f
[22:17] <SpeedEvil> Indeed.
[22:18] <Laurenceb_> i little odd
[22:18] <SpeedEvil> Especially given that you can knock out a large slice of that 1/f if you put the accel in.
[22:18] <Laurenceb_> ill check it did that right
[22:19] <Laurenceb_> hmm i think its wrong somewhere

[22:23] <Laurenceb_> http://i.imgur.com/HJr9Q.png
[22:23] <Laurenceb_> needed to transpose it before calling fft, thats much more sane
[22:24] <SpeedEvil> Looks pretty broadband
[22:24] <SpeedEvil> That's of a stationary spot?
[22:26] <Laurenceb_> yes
[22:26] <Laurenceb_> is gain different on different axes?
[22:27] <SpeedEvil> Clearly
[22:27] <SpeedEvil> It's a nice oval ball
[22:27] <hibby> hmm
[22:27] <SpeedEvil> ?hmm
[22:27] <SpeedEvil> It doesn't seem logical that it should be
[22:27] <SpeedEvil> Maybe it's mis-set
[22:27] <hibby> je suis hungry
[22:28] <Laurenceb_> i think this calls for spheroidfit
[22:28] <SpeedEvil> Was that one axis of fft?
[22:28] <Laurenceb_> yes
[22:28] <SpeedEvil> Or were you ffting the magnitude
[22:28] <Laurenceb_> one axis
[22:29] <Lunar_Lander> fft?
[22:29] <Lunar_Lander> fourier transformation?
[22:32] <Laurenceb_> yes
[22:34] <Lunar_Lander> yeah
[22:34] <Lunar_Lander> you need it for spectra and so on
[22:34] fsphil (~phil@2001:8b0:34:1:21f:c6ff:fe44:b25b) joined #highaltitude.
[22:35] <Laurenceb_> hmm cant get a good fit
[22:37] <SpeedEvil> It looks like ~300*300*150 or so enclosing box
[22:37] <Lunar_Lander> can the FFT be made Onboard?
[22:38] <SpeedEvil> So it's _very_ assymetric
[22:38] <SpeedEvil> Lunar_Lander: you can do FFTs, but they tend to really want reasonable speeds of maths.
[22:38] <SpeedEvil> In general it's a more useeful tool for analysis rather than onboard.
[22:39] <Lunar_Lander> yes
[22:39] <Lunar_Lander> so it's better to do that back at base?
[22:39] <BrainDamage> you can do it live, but if you can avoid it, it saves a lot of headaches
[22:41] <BrainDamage> try speclab, or an equivalent program, and ramp up the fft sample size, after 4k points or so, you'll see your pc starting to grind and the display not updating smoothly
[22:41] <Laurenceb_> ok got it
[22:41] <Laurenceb_> had to tweak it a little
[22:41] <Laurenceb_> ~170lsb/earth field
[22:43] <Laurenceb_> 1 micro tesla rms noise
[22:43] <Lunar_Lander> yeah I can imagine BrainDamage

[22:45] <SpeedEvil> Interesting.
[22:45] <SpeedEvil> I can't seem to find a published datasheet.
[22:45] <SpeedEvil> It looks like a clear setup error if one axes is 2* as sensitive as others
[22:46] <Laurenceb_> yeah full datasheet is nda
[22:46] <SpeedEvil> Some devices are insane.
[22:46] <SpeedEvil> The LED controller in my phone is a full CPU
[22:46] <SpeedEvil> Branch, add/sub instructions, ...
[22:47] <SpeedEvil> Just that it's only got 64 bytes or so of program storage
[22:47] <Laurenceb_> i see same range on all axes
[22:47] <SpeedEvil> umm
[22:47] <Laurenceb_> ~+-160
[22:48] <SpeedEvil> oh
[22:49] <SpeedEvil> Doh
[22:49] <SpeedEvil> If I make the gnuplot window square, it works.
[22:49] <NigeyS> wth
[22:49] <NigeyS> my altitude is ........ -49m :|
[22:49] <SpeedEvil> GPS altitude is regrettably bad.

[22:50] <NigeyS> not seen it this bad! i should be sodding scuba diving lol

[22:50] <Laurenceb_> thats gains and biases
[22:50] <Laurenceb_> bias=lsb, gain = normalised to earth field==1
[22:50] <SpeedEvil> I wish now I could recode my breadmaker and add an optointerruptor
[22:51] <SpeedEvil> Mix 20 mins -> wait 12h -> mix 5 min -> wait 12h ->bake
[22:51] <SpeedEvil> That's fairly spherical.
[22:53] <Laurenceb_> http://i.imgur.com/7H9vn.png
[22:54] <Laurenceb_> about 1% nonlinearity+hysterisis etc etc according to the spheroid fitter
[22:55] <Laurenceb_> - thats the corrected output plotted in 3d
[22:55] <SpeedEvil> I'd not believe that too strongly
[22:55] <SpeedEvil> I wasn't making that sure there was no iron nearby
[22:55] <SpeedEvil> So nails/...
[22:55] <Laurenceb_> also magnetic materials in the phone
[22:56] <Laurenceb_> on my dactyl board, there was extra nonlinearity after i populated everything
[22:56] <SpeedEvil> That too, but difffferent sorts of errors of course.

[22:58] <Laurenceb_> when you plot you cant zoom with the cursor
[22:59] <Laurenceb_> think theres some config somewhere it control how it calls gnuplot
