[03:24] <Darkside> as if
[03:25] <eroomde> today sure
[03:27] <eroomde> canni see anyone else in this history since midnight
[03:28] <eroomde> ergo, my flag, my country
[03:39] <Darkside> pff
[03:46] <nigelvh> It's not midnight yet.
[03:46] <nigelvh> (Not here anyway)
[03:47] <eroomde> i was going on gmt, it's the natural unit of timezones right?
[03:47] <eroomde> as al murray's pub landlord says, get a globe and look at britain. it's at the top, in the middle. damn right!
[03:48] <eroomde> (this is a comedy persona about a slightly xenophobic, slightly racist pub landlord who insults everyone)
[03:48] <nigelvh> Sounds like the stereotypical american. UHMEHRIKUH! Fuck yeah.
[03:49] <eroomde> occassionally he'll pick on an audience member in one of his stage shows
[03:49] <eroomde> 'where ya from sir?' and they'll say birmingham or something and he'll make the usual jokes
[03:49] <eroomde> but if some answers 'france' then you should see his face
[03:50] <eroomde> the whole audience knows what's coming
[03:50] <eroomde> back in 30 mins
[03:51] <nigelvh> Have fun!

[04:43] <eroomde> gave up coding about 3 hours ago to just watch stuff
[04:43] <Dan-K2VOL> :-)
[04:43] <Dan-K2VOL> that https://eyes.nasa.gov is very impressive for java
[04:44] <daveake> so sleeeepy
[04:44] <Upu> morning Mars fans
[04:44] <DrLuke> morning
[04:44] <Upu> yep that on one monitor Dan-K2VOL :)
[04:44] <x-f> morning
[04:44] <Dan-K2VOL> morning
[04:46] <Upu> sometimes engineering can be boring, other times we send a nuclear powered tank armed with frikken space lasers to another planet
[04:46] <fsphil> when did the word popular get replaced with "viral"?
[04:47] <fsphil> elvis!
[04:47] <Upu> "marketting"
[04:47] <Upu> one t
[04:48] <DrLuke> fsphil: years ago
[04:50] <Dan-K2VOL> here's a more technical feed without the commentators http://www.nasa.gov/multimedia/nasatv/media_flash.html
[04:51] <DrLuke> I'm watching the NasaJPL feed
[04:51] <Upu> I like the way they are just running Eyes on the Solar system too
[04:51] <fsphil> spotted that
[04:51] <fsphil> wish it worked here
[04:51] <DrLuke> haha yeah
[04:52] <Dan-K2VOL> ah Java, "it just works everywhere" :-P
[04:52] <DrLuke> oh god the stream froze
[04:52] <fsphil> hah
[04:53] <fsphil> java was a good idea, until they made it
[04:53] <Dan-K2VOL> lol
[04:54] Nick change: stilldavid_ -> stilldavid
[04:56] <fsphil> someone broke their headphone
[04:57] <fsphil> that hair can be used as a weapon
[04:58] <DrLuke> what the hell, why did they change to some random dude
[04:58] <Dan-K2VOL> lol
[04:59] <DrLuke> lol, someone WILL choke on those peanuts and the mission will fail
[04:59] <DrLuke> would be quite some twist
[04:59] <Dan-K2VOL> this is where we separate the men from the men who have peanut allergies
[05:00] <DrLuke> Haha did she just say penis instead of peanuts
[05:00] <Upu> Either that or the greasy fingers will slip and hit self destruct
[05:00] <Upu> bummer if you have a peanut allergy
[05:00] <DrLuke> yep
[05:01] <Dan-K2VOL> you know, I wonder what reference frame that speed refers to
[05:01] <daveake> Did he just say "In the nut too distant future"?
[05:01] <Upu> too early dave
[05:01] <Dan-K2VOL> oh that's lame
[05:01] <Dan-K2VOL> :-P

[05:05] <Upu> all these people and not a thing they can do to affect this
[05:05] <fsphil> was thinking that

[05:06] <fsphil> this guy is sensible

[05:07] <eroomde> this wise knowledge and all of this
[05:07] <eroomde> jesus
[05:07] <Upu> eroomde you need to watch a different stream :)
[05:07] <eroomde> no i like beign angry
[05:07] <Dan-K2VOL> haha
[05:07] <eroomde> i'm hope she'll shut up

[05:09] <Upu> haha
[05:09] <fsphil> adam is watching himself on that monitor
[05:10] <DrLuke> I wonder whether eyes shows realtime or adds the 14 minutes delay
[05:10] <eroomde> hey guys, i finally understand recurssion! ignorance has left the building!

[05:12] <fsphil> pyro!
[05:13] <eroomde> pyro separation makes me very nervous
[05:14] <eroomde> 'at this time' seems to be a traditional suffix on all announcements when landing on mars at nasa
[05:14] <Upu> well should have separated
[05:15] <Dan-K2VOL> it certainly did in the sim
[05:15] <fsphil> did
[05:15] <Upu> oh stop clapping :)
[05:15] <Dan-K2VOL> mmm I could use a cruise donut
[05:15] <daveake> Looks like a UFO now
[05:15] <daveake> Flying Saucer I mean
[05:15] <DrLuke> haha
[05:16] <daveake> Now it just needs to land near a red-planet redneck
[05:16] <DrLuke> in real time curiosity is about to land
[05:16] <DrLuke> or even already landed
[05:16] <Upu> 7 mins away DrLuke
[05:16] <DrLuke> oh
[05:17] <Upu> its just hitting the top of the atmosphere
[05:17] <DrLuke> oh right
[05:17] <DrLuke> light speed sucks
[05:18] <Upu> do we know if the MRO managed to rotate correctly ?
[05:19] <fsphil> odyssey did
[05:20] <Upu> sorry that one
[05:20] <Upu> eroomde
[05:20] <Dan-K2VOL> those martian satellites are really handy
[05:20] <fsphil> that's really going fast
[05:20] <Upu> want a rage ?

[05:20] <Upu> What an absolute waste of money and time. There is no life anywhere else. God created the universe and earth is the only planet which has life. It was created for our convenience. This money should have been spent on helping children in need.
[05:20] <Upu> top comment on the BBC news Article
[05:21] <fsphil> fsrage!
[05:21] <x-f> i hope Curiosity has actually landed by now
[05:21] <Dan-K2VOL> quite
[05:21] <DrLuke> it's still landing
[05:21] <Upu> its in the atmosphere
[05:21] <Upu> delay is about 7 mins
[05:22] <eroomde> at this time
[05:22] <Upu> lol
[05:22] <eroomde> i'm getting clues for my conference talk here
[05:22] <eroomde> do my hair slicky back with a quiff with lard
[05:22] <Dan-K2VOL> haha
[05:22] <fsphil> adam hasn't been on tv in a while, he's probably getting sad
[05:22] <eroomde> say 'at this time' a lot
[05:22] <daveake> :D
[05:22] <Dan-K2VOL> bring peanuts
[05:22] <eroomde> oh yes that too
[05:22] <Upu> Every time you do I'm going to hold a picture of Adam up
[05:23] <Dan-K2VOL> mars is getting really big in the sim
[05:23] <nigelvh> 90 seconds from entry
[05:23] <Dan-K2VOL> landing site has come into view
[05:23] <eroomde> he's all shook up
[05:23] <nigelvh> God damn this shit is awesome.
[05:24] <DrLuke> it's actually on the surface now (or not)
[05:24] <Upu> yup
[05:24] <DrLuke> well I guess either way it's on the surface
[05:24] <Dan-K2VOL> ooh pretty animatino

[05:25] <nigelvh> Yep
[05:25] <Dan-K2VOL> bet it's getting hot
[05:25] <nigelvh> Guided entry started.
[05:26] <Dan-K2VOL> so the sim is supposed to update live based on the tone transmissions
[05:26] <nigelvh> That's my understanding.

[05:40] <nigelvh> NERD PARTY!
[05:40] <costyn> will they visit the skycrane see how it landed? (dunno how far away it is?)
[05:40] <fsphil> that would be cool

[05:48] <Darkside> well that was very very cool
[05:48] <eroomde> yes

[05:49] <eroomde> ignores*
[05:49] <Dan-K2VOL> well on mars maybe, but venera, huygens?

[05:53] <eroomde> that's a first
[05:53] <Darkside> so what was that?
[05:53] <Darkside> was that the landing error?
[05:53] <eroomde> 0.04ish m/s
[05:53] <eroomde> no, landing velocity
[05:53] <Dan-K2VOL> 2km off target center I think
[05:54] <eroomde> horizontal anding velocity
[05:54] <Darkside> Dan-K2VOL: thats what i was after
[05:54] <nigelvh> if 2km is accurate that's amazing.
[05:54] <eroomde> previous landers have had quite a significant horizontal velocity at first contact. the airbag rovers rolled up to 0.5km after being released
[05:54] <Dan-K2VOL> I think it is pretty good considering it was a direct lob from the planet earth
[05:55] <DrLuke> It's like throwing a dart
[05:55] <eroomde> they have a few burns during cruise
[05:55] <eroomde> it's more like par 4 than par 1
[05:55] <Dan-K2VOL> :-) true
[05:55] <eroomde> not to say it's therefore easy of course
[05:55] <Darkside> lol nope, that link doesnt work
[05:55] <Dan-K2VOL> nice analogy
[05:55] <DrLuke> I think they didn't even do their last planned course correction because it was so perfectly on course
[05:56] <eroomde> yeah indeed
[05:56] <nigelvh> I think of it as hitting a target with a gun, from across the ocean, and you get a few lungfulls of blowing to adjust direction.
[05:56] <DrLuke> yep

[05:56] <mattltm> Amazing stuff
[05:57] <fsphil> very
[05:57] <Darkside> all broken images for me
[05:57] <DrLuke> yeah
[05:57] <eroomde> down for me too
[05:57] <DrLuke> that woman just said that all nasa pages are overloaded
[05:57] <Dan-K2VOL> hahah
[05:57] <radim_OM2AMR> server overloaded ?
[05:57] <DrLuke> damn budget cuts
[05:57] <Darkside> not surprised
[05:57] <Dan-K2VOL> yep
[05:58] <russss> the images are giving Amazon S3 access denied errors
[05:58] <fsphil> rtc is toasty hot
[05:58] <fsphil> rtg even
[05:59] <Dan-K2VOL> oh right, I forgot this sucker is nuclear
[05:59] <Dan-K2VOL> (sort of)
[05:59] <nigelvh> nucular?
[05:59] <fsphil> solar? pfft
[05:59] <Upu> well it works for Voyager ...
[05:59] <Dan-K2VOL> thermo-electricity generated by a nuclear plutonium pellet
[05:59] <nigelvh> Sun's not got enough power for us.

[06:00] <nigelvh> And an engineer! Perfect woman.
[06:01] <eroomde> find her number!
[06:01] <fsphil> fly-away was running normally
[06:01] <Dan-K2VOL> the plutonium decay creates heat, and the heat flows through thermoelectric generator modules
[06:01] <Dan-K2VOL> avionics fell asleep after landing :-P
[06:01] <Dan-K2VOL> darkside!
[06:02] <eroomde> it's because they didn't strap the batteries in properly
[06:02] <Darkside> ?
[06:02] <Dan-K2VOL> they're going to use Parkes
[06:02] <Darkside> well its part of the DSN
[06:02] <Darkside> so yeah
[06:02] <eroomde> if you don;t want to throw your rover don;t the stairs, don;t bloody launch it
[06:02] <fsphil> that looks like an ancient unix ui toolkit
[06:02] <Dan-K2VOL> I thought they were going to close that down

[06:03] <Darkside> oh man
[06:03] <Darkside> it was parkes!
[06:03] <Darkside> parkes got the mars landing :D
[06:03] <Dan-K2VOL> bravo down there
[06:04] <daveake> uh oh http://imgur.com/XSYwL
[06:05] <nigelvh> CRAP!
[06:05] <nigelvh> I did wonder how long it would take.
[06:05] <fsphil> could be worse, could be mermaids
[06:05] <craag> lol
[06:07] <DrLuke> Even the german morning news reports on curiosity
[06:07] <DrLuke> amazing
[06:07] <DrLuke> it's like the moon landing of our time
[06:08] <nigelvh> Alright, time for bed. Work tomorrow.
[06:08] <craag> And I frickin overslept..
[06:08] <nigelvh> evening all
[06:08] <nigelvh> Sorry craag
[06:08] <Dan-K2VOL> aw sorry craag
[06:08] <fsphil> nite nigelvh
[06:08] <nigelvh> it *was* awesome
[06:08] <fsphil> it's 7:10am here, might as well get up
[06:08] <fsphil> but it's monday and I'm on holiday so meh
[06:09] <eroomde> 'no earlier' than 11.15
[06:09] <eroomde> 11.15 if we get our shit together but you'll just have to bloody wait
[06:09] <eroomde> it's like they're habbers
[06:09] <craag> I woke up, pulled up nasatv on the tablet and there was some woman crying.. didn't know which way it had gone for a few seconds.
[06:09] <fsphil> hah
[06:10] <Dan-K2VOL> jealous, it's 2:10 am here, and it's time to go to bed, have a great day all :-) We've extended our reach a little farther off the planet!

[06:11] <MrScienceMan> has anyone used a bazooka dipole for a flight?
[06:12] <fsphil> I don't think the nasa budget is that bad yet
[06:13] <fsphil> I used this on my first flight: http://www.iw5edi.com/ham-radio/?the-vertical-bazooka-antenna,18
[06:14] <MrScienceMan> thats the one im asking about
[06:14] <eroomde> i have too
[06:14] <eroomde> usually don;t unless i need to
[06:14] <eroomde> for space constraints or something
[06:14] <fsphil> it's a bit longer than a 1/4 wave
[06:14] <eroomde> prefer 1/4 wave with ground plane
[06:14] <fsphil> and more difficult to keep straight
[06:15] <Darkside> i wonder how long until we get the images from the orbiter
[06:15] <MrScienceMan> few hours
[06:15] <MrScienceMan> probably
[06:15] <Darkside> ok
[06:15] <MrScienceMan> they need to get some higher res
[06:15] <MrScienceMan> wide angle camera and 64x64
[06:16] <MrScienceMan> such a bad combo
[06:16] <fsphil> there is a 256x256 version of the first image
[06:16] <MrScienceMan> fsphil: doesnt it work well, when its coiled up?
[06:16] <fsphil> lost signal before the second one received
[06:16] <MrScienceMan> i was planning to wrap it around my backpack
[06:16] <MrScienceMan> and test the tracker around town
[06:16] <fsphil> MrScienceMan: no antenna would, they work best when straight
[06:17] <fsphil> well unless it's a helical or something
[06:17] <Upu> its helical I think
[06:17] <eroomde> come on audio
[06:17] <eroomde> you can do it
[06:17] <eroomde> just beleive in yourself
[06:17] <Upu> its the thing that looks like an oversized Sarantel near the RTG
[06:18] <Upu> can get a picture back from Mars but can't get audio from USA
[06:18] <Darkside> whatever you do don't look at the ustream chat

[06:36] <DrLuke> that's pretty violent

[06:37] <radim_OM2AMR> Upu, it's not my video, I just received this link ;-)
[06:38] <Upu> that must have been through a big telescope
[06:39] <eroomde> someone got burst from the ground from ears with a consumer video camera. a decent one i think. but you could certainly see it burst. i think it might have beil neil futurity actually
[06:39] <eroomde> been*

[07:40] <Darkside> woo
[07:41] <Darkside> any info on link bandwidth?
[07:41] <eroomde> no
[07:41] <Upu> nope
[07:41] <eroomde> not heard a single number since the 500bps mentioned during edl
[07:41] <gonzo_> probably higher than 50bd rtty!
[07:41] <russss> I heard their UHF relay through Odyssey is about 10k bps
[07:41] <Darkside> hah
[07:42] <russss> best case
[07:42] <eroomde> that's quite meaty
[07:42] <gonzo_> the sizes of the DSN antennas that's prob not a tall order
[07:42] <gonzo_> poss is limited by the mars-orbiter link
[07:43] <fsphil> hehe, sun microsystems

[07:47] <fsphil> they better not lose them
[07:48] <Upu> she just did on the desk
[07:48] <russss> sounds like the link via Odyssey/MRO is still faster than the high gain
[07:48] <fsphil> I keep expecting to see dl-fldigi on a screen
[07:48] <Upu> altitude would be interesting
[07:49] <fsphil> $$MSL,104253,07:49:00,0.0000,0.0000,0,No Lock*AB42
[07:49] <Upu> lol yeah
[07:49] <pjm> from press kit: The rover can transmit to Odyssey at up to about 0.25 megabit
[07:49] <pjm> per second and to the Mars Reconnaissance Orbiter at
[07:49] <pjm> up to about 2 megabits per second.
[07:50] <russss> awesome
[07:50] <fsphil> impressive
[07:50] <russss> the 10k bps number was probably just for EDL then
[07:50] <fsphil> dataz
[07:51] <Upu> stop bloody clapping
[07:51] <russss> I still find it awesome that we have communications satellites on other planets.
[07:51] <pjm> also http://www.jpl.nasa.gov/news/press_kits/MSLLanding.pdf is well worth reading
[07:51] <fsphil> hehe, he has just phoned them to ask for the data
[07:51] <pjm> i want to see that tlm!
[07:52] <russss> where is my interplanetary internet
[07:52] <pjm> odyssey is just too weak to copy, u can see carrier but not sidebands
[07:52] <fsphil> show the pics

[08:01] <eroomde> costyn: yes it's massive
[08:01] <costyn> yea... also, large wind tunnel :)
[08:02] <eroomde> difficult to make anything much bigger
[08:03] <fsphil> that hazard camera has great dynamic resolution
[08:04] <russss> all the better to find extremely dark hazards
[08:05] <Upu> all very good
[08:05] <fsphil> yea
[08:06] <gonzo_> at least they didn't get the chute caught up in power lines/trees
[08:06] <Upu> might have been more impressive if they had
[08:12] <costyn> :)
[08:13] <eroomde> you'd have a load of habbers going 'it landed in a fucking tree fucking shit bum arse poo jesus daveake you jinxed it damn blah it's all a horrible failure 2 billion wasted gah"
[08:13] <fsphil> I was wondering why my laptop was getting so hot (started to burn me) --- java was running at 100% cpu since last night
[08:13] <eroomde> and a load of scientists going "There's a fucking tree on mars!!!!!!"
[08:14] <costyn> eroomde: hehehe :)
[08:14] <radim_OM2AMR> ..and f*cking power lines :-D
[08:15] <costyn> man that last bit was so over so quick, once they said the rockets on the crane were firing, it was like 30 seconds later they said 'touchdown confirmed'. I guess I've been spoilt by movies & film where the climax is nicely spread out and detailed :)
[08:16] <costyn> "The rover´s descent camera begins taking a movie of the remaining five-mile flight to the ground." <-- when do we get to see this?!?!
[08:16] <costyn> do want
[08:17] <eroomde> probably during a higher pass of one of the orbiters
[08:17] <fsphil> not for a while
[08:17] <costyn> gonna take a while to upload I guess
[08:18] <fsphil> shame we'll never see a pic of the skycrane working
[08:18] <costyn> yea
[08:18] <pjm> i wonder if the skycrane did a controlled landing
[08:18] <fsphil> the data is more important though
[08:19] <costyn> must've looked quite impressive from the ground, this thing comes roaring in, fires rockets, hovers, and lowers down a recon vehicle. Straight outta scifi if you ask me :)
[08:19] <fsphil> just sci now :)
[08:19] <costyn> pjm: in the animations the skycrane just angles and fires full on, flying off into the distance, so no :) it crashed
[08:19] <fsphil> shame too, it had enough fuel
[08:20] <pjm> yeah will be interesting to find out
[08:20] <fsphil> although there would be no gain to it
[08:20] <pjm> well crashing would cause polution
[08:20] <fsphil> and having it doing manouvours after seperation would be a risk to the rover
[08:21] <costyn> wonder if there was a camera on the crane pointing down showing the rover being lowered
[08:22] <fsphil> dunno, but if there wasn't there should have been :)
[08:22] <costyn> :)
[08:23] <costyn> but I guess there won't be an 'extended' mission on this rover as with the other 2, seeing as the powersuppy is limited right?
[08:25] <Darkside> hmm, how long will the RTG last?
[08:26] <costyn> . The primary
[08:26] <costyn> mission will last one Mars year (98 weeks).
[08:26] <fsphil> bbc is saying decades, but no idea where they got that from
[08:27] <fsphil> I doubt the mechanisms will last that long
[08:27] <costyn> fsphil: well not from the press kit :)
[08:27] <costyn> (that's wher I copy/pasted from)
[08:28] <fsphil> right, time for breakfast
[08:28] <x-f> i heard, that after primary mission RTG will have power output of about 80%, so it definately will be extended
[08:28] <fsphil> cheese on toast, yum
[08:28] <costyn> x-f: ah, nice
[08:29] <fsphil> I'd have a Mars bar but I don't think I could eat chocolate this early
[08:30] <costyn> fsphil: actually it's the other ingredients I couldn't stomach: the massively sweet fudgy stuff inside
[08:30] <fsphil> yea, it's a bit heavy
[08:30] <costyn> ugh... work. So not in the mind-set for work
[08:31] <costyn> seems so banal
[08:31] <fsphil> back to earth
[08:31] <gonzo_> chocky for breakfast?! That';s what women do isn't it?
[08:32] <gonzo_> (real men have reheated pizza, from the previous nights binge)
[08:33] <SamSilver> iwent balls to the wall and had left-over pizza forsuday breakfast - unheated!
[08:33] <SamSilver> smoked chicken and jalapeno
[08:34] <costyn> SamSilver: i love cold pizza
[08:34] <fsphil> my cheese on toast suddenly seems inadequate
[08:34] <gonzo_> hehe, I must be going soft in my old age, was muesli this morn
[08:35] <SamSilver> i find ones with bacon or salami are great cold
[08:35] <costyn> maybe your cheese is just not up to par; ripened dutch cheese on toast is godly
[08:35] <SamSilver> even sausage or mincew
[08:35] <gonzo_> Real mand breakfast must be Hab rolls!
[08:35] <SamSilver> a strong gouda or a cheddar?
[08:35] <eroomde> i had hab rolls this morning
[08:36] <SamSilver> for sat brunch (watching rugby) had a bacon butty with cheese and then sunday at the fleamarket had a bacon butty with egg
[08:37] <SamSilver> prefer just bacon and hp sauce
[08:37] <costyn> SamSilver: Gouda I think. We're not much for cheddar here
[08:38] <SamSilver> if i were king i could easily give up my kingdom for cheese
[08:39] <SamSilver> wathcing this it is great > http://www.youtube.com/watch?v=Y7ZBLklsUys > 1h 49 min 35secs long

[09:01] <MrScienceMan> 1/4 is atleast a meter for 144

[09:01] <fsphil> ah, 2m
[09:02] <fsphil> I've a little magmount antenna that's about 40cm long and works on 2m
[09:03] <fsphil> a 1/4 will actually be about 50cm on 2m
[09:03] <fsphil> a bit less
[09:04] <MrScienceMan> is that the spiral type one?
[09:04] <fsphil> nah, just standard quarter wave
[09:04] <MrScienceMan> but its ready made
[09:04] <MrScienceMan> ?
[09:05] <fsphil> I'm sure you can buy them, but they're easy to make
[09:06] <fsphil> the antenna I mentioned earlier is: http://cpc.farnell.com/watson/wsm-270/wsm-270-mini-mag-antenna/dp/IT44456
[09:07] <fsphil> but it could really do with a ground plane
[09:07] <MrScienceMan> i find making a bazooka
[09:07] <MrScienceMan> much easier and cheaper
[09:07] <fsphil> always worth a try
[09:08] <MrScienceMan> might try the 1/8
[09:08] <MrScienceMan> see how it does, maybe convert it to 1/4 later
[09:08] <MrScienceMan> i had the ground plane on my backpack
[09:09] <MrScienceMan> few people almost lost an eye each
[09:09] <MrScienceMan> :D

[09:09] <fsphil> yea pointy spikes of doom never go down well
[09:10] <MrScienceMan> was in an elevetor with it

[09:15] <gonzo_> a 1/4wave will be about 50cm for 2mtra
[09:15] <SQ9OZD> hi, who knows good CHDK script to get intervals: series of pictures (5s interv.) and then video ?

[09:15] <gonzo_> a 1/8th wave will need special matching as it won't be anything near 50R at the feed
[09:16] <gonzo_> if you want small, put a bnc connector of a bit of plate (or use wires for the groundplane) and put a rubber duck on that]
[09:17] <craag> I'd try a slim-jim/jpole, but then coil the half-wave radiator a bit to make it shorter.
[09:18] <craag> I did plan to build one, but now the local repeaters gone, 2m is pretty much dead unless you can get onto a hill to get the next repeater over.

[09:30] <russss> is the raw hirise imagery somewhere?

[10:20] <Darkside> eroomde: we did 10km
[10:20] <eroomde> that's like 10 times not good enough Darkside
[10:20] <Darkside> if we had better low altitude wind models we could have made that a bit smaller
[10:21] <eroomde> i mean not so much predict the spot (heck we've done 300m odd) but be able to actively be told to go there 3 days before launch
[10:21] <Darkside> ahh
[10:21] <Darkside> yeah thats a bit harder :P
[10:21] <Darkside> this was more ok, if we cut it down now it'll land within a certain radius of us
[10:21] <eroomde> like a planetrary lander
[10:22] <eroomde> yeah when in flight with our esa vehicle the predicted point was about 150m from the actual landing point at the point of commanding separation
[10:22] <eroomde> i was impressed with that
[10:22] <Darkside> oh nice
[10:22] <Darkside> fromw hat altitude?
[10:22] <Darkside> our problem was low altitude winds were very different from the prediction
[10:22] <eroomde> 25ish km i think it was
[10:22] <Darkside> and it got caught in a thermal at about 1km alt

[10:25] <Darkside> parachute dynamics?
[10:26] <eroomde> is that a question?
[10:26] <Darkside> i mean you modelled it
[10:26] <Darkside> nvm
[10:26] <eroomde> yeah we knew the Cd and the srea
[10:26] <eroomde> area*
[10:26] <Darkside> mm ok
[10:26] <Darkside> we've just been using 'pred'
[10:27] <Darkside> lol
[10:27] <eroomde> sure but you have to put in a descent rate to pred
[10:27] <eroomde> and you get that from knowing the cd and the area
[10:27] <Darkside> yeah
[10:27] <Darkside> true
[10:27] <eroomde> it's no different to this
[10:27] <Darkside> though we usually guess >_>
[10:27] <Darkside> 'meh, about 5m/s'
[10:27] <Darkside> usuallt works
[10:27] <eroomde> where hab people do have problems is when they use awful parachutes
[10:27] <eroomde> which have glide rations of like 1:1
[10:27] <eroomde> ratios*
[10:28] <Darkside> heh
[10:28] <Darkside> eroomde: you've seen the horus 25 video, right?

[10:29] <Darkside> thate the video for cutdown test #2
[10:29] <eroomde> nice
[10:29] <eroomde> will let it buffer for a bit
[10:29] <Darkside> but anyway
[10:29] <Darkside> about 1km from landing, the descent rate went right down
[10:29] <Darkside> to like 0.1m/s
[10:30] <Darkside> we got to watch it for a good 5-10 minutes, just sloooooooooowly floating down in front of us
[10:30] <eroomde> we have not flown anything with an uplink since 2010. I am not sure why.
[10:30] <Darkside> we got to see how the radar reflector and parachute interacted, which was very interesting
[10:30] <Darkside> the radar reflector acted like a rudder
[10:31] <eroomde> i think maybe it didn't quite survive the technology transfer process to the newer cusf bunch
[10:31] <Darkside> mm
[10:31] <Darkside> i'm going to be making the case that everyone switches to RFM22Bs
[10:31] <Darkside> i still need to look at better clocks for them
[10:31] <Darkside> i mean, better crystals
[10:31] <eroomde> is there a case for it?
[10:31] <Darkside> but i think the RFM22b is a btter option for general RTTY telemetry
[10:31] <Darkside> maybe not for experimental modes
[10:32] <eroomde> why?
[10:32] <Darkside> minimum shift is 165Hz
[10:32] <Darkside> probably not suitable for MFSK modes
[10:32] <eroomde> sounds like a reason not to switch to them then

[10:33] cuddykid (~acudworth@host-78-145-193-219.as13285.net) left irc: Quit: cuddykid
[10:33] <Darkside> i mean, half the price of a NTX2
[10:33] <Darkside> though maybe you guys get the NTX2's cheaper
[10:33] <Darkside> but frequency agility + uplink capability + cheap is very nice
[10:33] <Darkside> and tbh, from the launches i've run with them, the frequency drift is *less* than that of the NTX2
[10:34] <Darkside> downsides are: not as simple to interface with, needs regulated 3.3v, output power is a bit questionable
[10:34] <eroomde> but the ntx2's drift can be temp compensated to be even better than an rfm22 surely
[10:34] <Darkside> eroomde: perhaps
[10:35] <Darkside> but the problem with the rfm22b is that its using a crystal with low thermal mass
[10:35] <navrac_work> questionable - but can be varied. Also takes more current than an ntx
[10:35] <Darkside> navrac_work: oh it does?
[10:35] <Darkside> even at 10mW?
[10:35] <navrac_work> yep
[10:35] gonzo__mob (~gonzo_mob@213.205.233.235) left irc: Ping timeout: 246 seconds
[10:35] <Darkside> damn
[10:36] <Darkside> the crystal is pretty easy to replace on it though
[10:36] <eroomde> i think i'll stick with the ntx2. if you don't mind use ham powers to uplik then there are absolutely loads of ways of doing uplinks
[10:36] <Darkside> and theres a pad on there for a HC49 crystal
[10:36] <Darkside> eroomde: its nice to have it all in one
[10:36] <eroomde> and ntx2 gives me the option to do continuously varible things
[10:36] <Darkside> yes
[10:36] <eroomde> Darkside: i dunno
[10:36] <Darkside> ntx2 is good for experimental stuff
[10:36] <eroomde> it's simplex
[10:36] <eroomde> that's not to useful to me
[10:36] <navrac_work> To overcome the drift I put copper over the IC and Xtal coupled by heatsink compound then covered with epoxy

[10:36] <eroomde> i'd rather have a dedicated down freq and a separate up freq that i can use at any time
[10:36] <Darkside> eroomde: i'm focusing more on a reliable cutdown/positioning telemetry payload
[10:37] <Darkside> eroomde: yeah thats a valid point
[10:37] <eroomde> i.e. full duplex
[10:37] <eroomde> sure, i agree it's good for that
[10:37] <Darkside> doing that within 70cm is difficult though
[10:37] <Darkside> we have heaps of trouble with intermode on our voice repeaters
[10:37] <Darkside> intermod*
[10:38] <Darkside> with enough physical separation its ok though
[10:38] <eroomde> but you said that you were going to make the case that 'everyone switches to rfm22'
[10:38] <Darkside> :P
[10:38] <Darkside> yea ok
[10:38] <eroomde> sure but why do both on 70cm then?
[10:38] <eroomde> just upink on 2m or 5ghz or something
[10:38] <Darkside> heh
[10:38] <Darkside> in our case 2m is out
[10:38] <Darkside> for you guys, maybe
[10:39] <Darkside> we can't use 2m as the APRS payload will wipe it out
[10:39] <eroomde> sorry to be pedantic :0
[10:39] <eroomde> :) *
[10:39] <Darkside> yeah yeah
[10:39] <navrac_work> The biggest issue I have with the rfm22 is that if you turn off the carrier to conserve power, the chip then slowly floats on to the right frequency - so you need to keep it powered up and txing all the time
[10:39] <Darkside> navrac_work: i haven't had issues with power tbh
[10:39] <Darkside> well
[10:40] <Darkside> i had a GPS + RFM22B transmittin 25mw for 7 seconds, listening for 3, running for 12 hours off a single AA lithium
[10:40] <eroomde> anyway that vid has buffered so will watch it now
[10:40] <radim_OM2AMR> Very nice reportage Darkside !
[10:40] <Darkside> pff not me
[10:41] <Darkside> thats done by our team filmographer
[10:41] <Darkside> his work has been getting more and more professional lately
[10:41] <radim_OM2AMR> anyway, great professional presentation ;-)
[10:42] <eroomde> i love these horus videos
[10:42] <eroomde> best hab stuff on the net atm
[10:43] <Darkside> heh, thanks

[10:46] Paul2 (~paul@rofl.in) joined #highaltitude.
[10:47] <Darkside> eroomde: so yeah, now we've proved the cutdowns worth, and proved the switchmode boost converter doesn't kill the RX, we're going to be moving to a combined cutdown + telemetry payload
[10:47] <Darkside> all running off 2xAAs.
[10:47] <Darkside> or possibly 2xAAAs for shorter flights, but tbh i'd prefer to have the extra runtime just in case
[10:48] <eroomde> never hurts if you can spare the mass
[10:48] <Darkside> the fun part about the boost converter is that once the battery gets low enough that the system can't completely boot, it still gets far enough that the radio fires up and broadcasts a few tens of ms of carrier
[10:48] <Darkside> and does this in loop for another 2 hours
[10:48] <Darkside> so even after it stops broadcasting gps positions, we still have another 2 hours to DF the thing
[10:49] <eroomde> nice

[10:50] Martian_Lander (~kglinka@cip25.informatik.uni-osnabrueck.de) left irc: Client Quit
[10:50] <Darkside> the other cool thing about the boost converter, is it handles the voltage sag from running the nichrome wire off the same batteries
[10:50] Martian_Lander (~kglinka@cip25.informatik.uni-osnabrueck.de) joined #highaltitude.
[10:50] <Darkside> batteires sag from 3v to about 2v, boost converter just keeps on trucking along..
[10:50] <kokey> oh, reliable cutdowns?
[10:50] <Darkside> what i haven't tested is the ability for it to cutdown after 12 hours or so of flight time
[10:50] <Martian_Lander> NASA and JPL made it!!!
[10:51] <Darkside> if the voltage drops down below 0.8v during firing, it'll reset
[10:51] <Darkside> kokey: we've flown a nichrome wire based cutdown on our last 4 flights, with 100% succss
[10:51] <Darkside> success*
[10:51] SamSilver_ (2985f5c8@gateway/web/freenode/ip.41.133.245.200) left irc: Quit: Page closed
[10:51] <Darkside> i'm pretty happy with it, of course it needs more testing
[10:52] <Darkside> what it also needs is a method for checking that the nichrome wire is still connected
[10:52] <Darkside> there is feedback in the form of battery voltage measurements, during the cutdown
[10:52] <Darkside> lets me know how far the battery drops to
[10:53] <kokey> you just supply voltage to it and it melts?
[10:53] <Darkside> yeah, you need to know the resistance of the nichrome wire though
[10:54] <Darkside> it ends up drawing approx an amp
[10:54] <kokey> I wonder if you could do it with a capacitor
[10:54] <Darkside> yep, that'd probaly help a lot
[10:54] <Darkside> i mean, a large cap in parallel with the batteries would help lower the voltage drop
[10:55] <kokey> yeah that too, but I'm wondering how reliable one would be charged up pre launch
[10:55] <Martian_Lander> (I'm Lunar btw :P)
[10:55] <Darkside> mm not sure
[10:55] <gonzo_> or a super cap on the proc side to keep the cpu gaing during the cut
[10:55] <Darkside> gonzo_: yep another good idea
[10:55] <Darkside> gonzo_: though the boost converter handles that too
[10:55] <Martian_Lander> I think you'd need to exert a great amount of work to charge the supercap
[10:55] <kokey> yeah makes more sense to just use it to handle spikes than to power the cutoff itself
[10:56] <kokey> otherwise you'd have to manage it and recharge it on failure etc.
[10:57] <Darkside> mm
[10:57] <Darkside> i mean, the absolute safest way is to run the nichrome off another set of batteries
[10:57] <Darkside> thats how we've been using the cutdown board so far
[10:57] <gonzo_> yep better idea
[10:57] <Darkside> 4xAAs -> LDO -> mcu + radio
[10:57] <Darkside> and another 2xAAs for the cutdown
[10:57] <Darkside> but it adds weight
[10:57] <kokey> has anyone launched a payload on a sky lantern?
[10:58] <Darkside> now i can lower that to 2xAAs for the mcu +radio, and 2xAAAs for the nichrome
[10:58] <gonzo_> ugh, awful things
[10:58] <Martian_Lander> yea fire hazard
[10:59] <Martian_Lander> for example AFAIK they are banned in all of Germany
[10:59] <gonzo_> quite rightly
[10:59] <gonzo_> I see them near me regulrly
[10:59] <Martian_Lander> yea they are banned in 15 of 16 states
[11:00] <radim_OM2AMR> Martian_Lander - changed identity of Lunar_Lander ? ;-)
[11:00] <Martian_Lander> yeah :)
[11:00] <Martian_Lander> as I said above
[11:00] <Martian_Lander> [12:55] <Martian_Lander> (I'm Lunar btw :P)
[11:00] <gonzo_> I suppose there is no need to fly a tracker on a lantern, just track by listening for the fire engines
[11:00] <Martian_Lander> yea
[11:00] <kokey> just thinking of a simple way to test experiments with parachute designs
[11:00] <Martian_Lander> xD
[11:00] <radim_OM2AMR> Martian_Lander: Yeah :-)
[11:01] <Martian_Lander> gonzo_: yeah they have been totally banned here
[11:01] <Martian_Lander> but one of the states like lifted the ban partially again
[11:01] <costyn> I have let some up on the beach when the wind was out to sea
[11:01] <kokey> perhaps a country where it rains all the time and everything is green and wet even in winter

[11:02] <Martian_Lander> oh
[11:03] <Martian_Lander> Austria has banned them too
[11:03] <Martian_Lander> Switzerland allows them here and there
[11:03] <costyn> Martian_Lander: NL too
[11:03] <kokey> I can understand austria, go above a certain altitude at certain times of the year and things are proper dry
[11:03] <costyn> but how do they come down if they're still lit?
[11:04] <kokey> I think only if they fail, or launched badly
[11:04] <kokey> but that probably happens a lot
[11:04] <Martian_Lander> costyn: maybe if they hover low and are still burning and hit something
[11:05] <kokey> I guess I'll just fork out on the helium, could be cheaper than the risk
[11:05] <Martian_Lander> I think I once saw a makeshift model made of a supermarket paper bag
[11:05] <Martian_Lander> i.e. there was an object in the sky that oscillated and you could see a little flame
[11:05] <Martian_Lander> and it wasn't much higer than the trees
[11:06] <kokey> perhaps a reusable mini hot air balloon engineered to be safe
[11:06] <Martian_Lander> that was in the summer of '08
[11:06] <Martian_Lander> when they were still allowed
[11:06] <kokey> I wanted to do parachute experiments when I lived in a flat right underneath the penthouse, on the 13th floor
[11:07] <kokey> in gibraltar tho, right by the marina and the airport, hence why I didn't do it
[11:07] <Martian_Lander> yea
[11:07] <Martian_Lander> Gibraltar still belongs to England right?
[11:07] <kokey> in fact, the height of the apartments were determined by the airport, that's why each tower block was a different height

[11:08] <Martian_Lander> what I always wanted to know
[11:08] <Martian_Lander> I once read a book by a guy who sailed across the atlantic from there and he talked about the lights of Europa Point
[11:08] <Martian_Lander> is there something like that on Gibraltar?
[11:09] <kokey> yeah, the southern end of gibraltar, is called europa point
[11:09] <kokey> there's a lighthouse there
[11:09] <Martian_Lander> ah
[11:09] <Martian_Lander> thanks
[11:10] <kokey> there's not that much else there, so it's almost the darkest end of gibraltar
[11:10] <kokey> but probably the most dangerous
[11:10] <kokey> ships do crash into it
[11:10] <kokey> they underestimate the tide
[11:11] <kokey> and because it's where the atlantic flows into the med, and there's a temperature difference, it's both rough and it causes fog
[11:11] <kokey> normally when people sail from the med to go across the atlantic, they stop in gibraltar
[11:11] <Martian_Lander> ah
[11:11] <kokey> fuel is cheap there etc.
[11:11] <Martian_Lander> col
[11:11] <kokey> next stop is somewhere in morocco usually
[11:12] <Martian_Lander> ah

[12:43] <AlephHaz> hallo. bought my arduino mini pro and an ftdi breakout. i'm a bit of a newbie at prototyping so i was wondering if people could recommend a list of items for assembling a board? i'll be going with right angle male headers for the programming header to plug in the breakout, with female headers for the rest of the arduino's contacts
[12:45] <eroomde> some people find breadboard useful for their experimentation
[12:45] <eroomde> (in which case male headers on the arduino pro mini)
[12:45] <AlephHaz> aha
[12:46] <eroomde> that way you can get the bits you want to use (gps, ntx2 or whatever) and wire them up non-permanently while you get your head around the programming side
[12:46] <AlephHaz> https://s3.amazonaws.com/sfecdn/tutorialimages/ArduinoProMini_Landing/large_MiniBreadboard.jpg
[12:46] <eroomde> and you might be in a better position to know how everything needs to be wired up (and thus what kind of connectors and wires you want) once that coding bit is done and it's working on the bench
[12:47] <AlephHaz> i was wanting something similar to that
[12:47] <eroomde> exactly so
[12:47] <AlephHaz> woop, so just a heck load of male headers then?
[12:47] <AlephHaz> and wires ofc.
[12:47] <AlephHaz> i'll get some LEDs to have a play around with as well
[12:49] <eroomde> yeah indeed
[12:49] <eroomde> so some solic core wire
[12:49] <eroomde> and strippers
[12:49] <eroomde> and then general electronicsy bits like resistors or whatever you think you'll need
[12:50] <eroomde> I must emphasise first tho (i'm sure you realise but just incase) breadboard is not really suitable for flying
[12:50] <eroomde> just bench testing
[12:50] <eroomde> you'll want proper mechanical or soldered connections for flight hardware
[12:50] <AlephHaz> i see
[12:50] <eroomde> but it's great for testing the circuit and writing the code
[12:50] <AlephHaz> can you recommend a board?
[12:51] <Darkside> they're all teh same really
[12:51] <eroomde> oh no, i have no idea
[12:51] <eroomde> there are thousands and millions of broadboards
[12:51] <AlephHaz> that's meant for post-prototyping
[12:51] <AlephHaz> ah
[12:51] <eroomde> they're all basically the same
[12:51] <eroomde> oh for post prototyping, well you have options
[12:51] <AlephHaz> yeah :p
[12:51] <eroomde> some people just solder stuff with wires directly to each component
[12:51] <eroomde> eg daveake's tiny tracker
[12:52] <AlephHaz> have you guys got any pictures of finished projects/prototypes on ukhas?
[12:52] <eroomde> well that failed

[12:59] <Josh_> Hi guys. in the middle of doing some testing when my gopro overheated after an hour of filming inside the payload! anyone else had this trouble? any ideas on ventilation?
[13:01] <kokey> I guess you shouldn't let it keep filming when you're on the ground
[13:01] <eroomde> it will only get hotter at alt

[13:02] <eroomde> Josh_: no
[13:02] <AlephHaz> i don't see myself using that many wires, and it will only be non-permanent
[13:03] <AlephHaz> for now. :P
[13:03] <Josh_> hmmmm i've gone from not needing a hand warmer to possibly needing an ice pack! :D
[13:03] <eroomde> is the gopro being ventilated in any way now?
[13:04] <Josh_> not at the moment, it fits snugly into the bottom of my payload
[13:05] <Josh_> but i was thinking of inserting some straws from either side into the gopro compartment
[13:05] <Josh_> could help?
[13:05] <AlephHaz> doesn't electronics get hot when it gets to less dense altitudes iirc? apparently because the heat doesn't have anyway to dissipate, but i assume that's only if you're working with higher clock rates
[13:05] <AlephHaz> overheat*
[13:05] <eroomde> AlephHaz: correct
[13:05] <AlephHaz> boom :P
[13:05] <eroomde> Josh_: might help
[13:05] <eroomde> whatever gets more air in
[13:05] <Josh_> mm yeah
[13:06] <eroomde> traws might not be enough though

[13:07] <AlephHaz> ooh, one more question. how many li-ion energizer's do you reckon i'll need for a full flight? obviously i'm wanting to minimise weight, and i'll only be powering a ntx2 and a max-6 w/ sarantel antenna
[13:07] <Darkside> AlephHaz: as many as you need to supply enough voltage
[13:07] <Darkside> or more accurately, enough to supply enough voltage to supply whatever regulator you sue
[13:07] <eroomde> usually when I reach a problem in hab that I can't solve, having done over 80 flights, i turn to the exlusive guide
[13:07] <Darkside> work it out

[13:21] <cuddykid> looks like I missed Josh_
[13:22] <AlephHaz> so i should start adding batteries to a pack while measuring the voltage between the two ends, and once it reaches above 3.5V i can then finish it there and start wiring it to the RAW pin?
[13:22] <eroomde> yes yes apologise to him for me at the weekend

[13:23] <costyn> AlephHaz: you should be familiar with what power/voltage regulator you are using. Some of them need more power than that

[13:24] <costyn> AlephHaz: you can use the onboard one or solder your own

[13:31] MrScienceMan (~zo@46.47.80.192) left irc: Ping timeout: 240 seconds
[13:32] <daveake> AlephHaz: You need to know - what voltage your processor runs at (5V or 3.3V); the "dropout" voltage of the regulator (look it up in the datasheet for the regulator); the voltage from each cell when nearly flat (1V - 1.2V for a Energizer Lithium).
[13:33] <daveake> So if say it's a 5V CPU and 1V dropout, you need 6V. Which, depending on how flat the cells are before it all stops, means 4-6 cells.
[13:33] <daveake> Those Lithiums have a near-vertical discharge at the end, so they drop from 1.2V to 1V pretty quickly.
[13:33] <fsphil> no sign of the mars odyssey image yet?
[13:33] <daveake> 5pm
[13:34] <fsphil> awwww

[13:56] <kokey> will the 3.3v arduino run ok on a 4.5v input and be a good 3.3v source for other modules?
[13:56] <Randomskk> no
[13:56] <Randomskk> well
[13:56] <Randomskk> which arduino precisely? generally, no
[13:56] <kokey> arduino pro mini
[13:57] <Randomskk> no
[13:57] <Randomskk> it needs a 3v3 source
[13:57] <Randomskk> you could get a 3v3 low-dropout linear voltage regulator and supply that with the 4.5V and it would make a 3v3 source for the arduino and other parts
[13:58] <daveake> The 3.3V mini pro does have a very good (0.2V) LDO on it
[13:59] <kokey> I thought the raw pin on the pro mini goes to a on board voltage regulator
[13:59] <daveake> It does
[13:59] <Randomskk> ...huh, that's what I get for talking without checking
[13:59] <Randomskk> >_> sorry
[13:59] <daveake> I get about 15 hours from 3 AAAs into one of those (with UBlox / rfm22b)
[13:59] <daveake> :D
[13:59] <kokey> ah ok cool
[13:59] <Randomskk> pretty sure my 3v3 arduino doesn't have that. sigh.
[13:59] <daveake> It's the one I use all the time so I know it well :D
[14:00] <costyn> daveake: how many mA can the reg provide?
[14:00] <daveake> Actually everything works down to about 3.1V *into* the regulator
[14:00] <costyn> impressive
[14:00] <daveake> 300mA
[14:00] <daveake> Though it might get warm :D
[14:00] <kokey> I've been doing all my work so far with 2xAA batteries but realised that when they run out of juice it might be better to run off a 4.5v combo
[14:00] <costyn> 300 is more than enough then :)
[14:01] <daveake> yep
[14:01] <Darkside> kokey: for my LDo based payloads i usuall fly with 4 batteries
[14:01] <Darkside> though i was using a LDO with a crap dropout voltage
[14:01] <costyn> daveake: 5v?
[14:01] <daveake> With 4 fresh Lithiums it gets warm enough to tell with a finger, but not warm enough to worry about, when running a normal payload
[14:01] <costyn> sorry
[14:01] <costyn> that was meant for Darkside
[14:01] <Darkside> costyn: 6v
[14:02] <Darkside> depends on the dropout voltage of the regulator
[14:02] <Darkside> i wanted to stay well above it
[14:02] <daveake> Some manufacturers have a different idea of what "Low" in LDO means. 1.5V ain't low IMO
[14:02] <daveake> I think <2V is enough for some of them
[14:02] <costyn> yea daveake provided me with protip of using the LM2940CT-5
[14:03] <daveake> Yeah, I made a list of all the ones I've got here and their dropout voltages @100 and 300mA
[14:03] <Darkside> yeah lol
[14:03] <Darkside> i use one now which has a 150mV dropout voltage
[14:03] <costyn> Darkside: impressive, what is it?
[14:03] <daveake> that's as good as tey get
[14:04] <Darkside> http://www.ti.com/lit/ds/symlink/tps76633.pdf
[14:04] <Darkside> i wouldn't feed it with more than 6v though
[14:04] <Darkside> you'll exceed the power dissipation

[14:07] <WillDuckworth> 1.8v gps?
[14:07] <Darkside> this was using a boost converter
[14:07] <Darkside> up to 3.3v
[14:08] <Darkside> it ran down to 0.85v
[14:08] <Darkside> of course, at that point it was drawing like 1.5A peak current...
[14:09] <daveake> !!
[14:09] <Darkside> yeah
[14:09] <daveake> Saw similar with the 1402
[14:09] <Darkside> yep
[14:09] <Darkside> this is using a TPS61200
[14:09] <daveake> Yeah, same as Upu has on his board?
[14:10] <Darkside> id probably suggest runnign it off 2xAAs :-)
[14:10] <Darkside> yep
[14:10] <Darkside> he got the idea off me >_>
[14:10] Action: UpuWork looks up
[14:10] Action: UpuWork goes back to sleep
[14:10] <daveake> efficiency does bomb a bit on a single cell
[14:10] <Darkside> yep
[14:10] <Darkside> still, 12 hours isn't that bad
[14:10] <daveake> No, it's fine
[14:10] <Darkside> though the cell voltage does drop with cold
[14:10] <Darkside> that may reduce lifetime a bit
[14:10] <daveake> That's the other worry
[14:11] <Darkside> hence using 2 cells
[14:11] <Darkside> unless you're *really* streched for weight, you may as well
[14:11] <UpuWork> 1 AA works
[14:11] <daveake> When I did a freezer test on 3 AAAs it stopped, so I removed from the freezer, then a couple of minutes later it started up again
[14:11] <daveake> Think I got an extra 30 minutes from them at room temp
[14:11] <Darkside> UpuWork: have you flown with 1xAA?
[14:11] <UpuWork> no
[14:11] <UpuWork> tested 1 x AAA though twice
[14:12] <UpuWork> first with no power saving, then with power saving
[14:12] <UpuWork> 4.5hours vs 6.5hours
[14:12] <Darkside> i'm just concerned about what happens to the cell voltage with cold
[14:12] <daveake> Drops
[14:12] <Darkside> lower cell voltage means more current draw, and possibly reduced life
[14:12] <daveake> :D
[14:12] <UpuWork> only one way to test it
[14:12] <UpuWork> daveake
[14:12] <UpuWork> launch it pls

[16:38] <DrLuke> I wonder if they managed to get any pictures of the powered descent
[16:38] <Darkside> not for a few days
[16:38] <Darkside> they need to get the high gain antenna up

[17:00] <Martian_Lander> Gadget-Mac, awesome!
[17:00] <Martian_Lander> even cooler than the photo of Phoenix landing
[17:01] <Martian_Lander> Phoenix was just a white streak or sort of
[17:01] <costyn> is your guys sound becoming softer and louder ?
[17:01] <nigelvh> Yeah, they're messing with the mixing live.
[17:02] <costyn> annoying :)
[17:02] <nigelvh> Yeah
[17:02] <Martian_Lander> earlier I saw a guy reading BILD
[17:02] <Martian_Lander> that is like "The Sun"
[17:03] <Martian_Lander> and there was a article "Why did we send $2.3 billion to Mars?"
[17:03] <nigelvh> Because we kick ass.
[17:03] <nick_> To appease the martians of course.
[17:03] <Martian_Lander> I didn't see it but I assume it was written by that guy who ranted about the investments into LHC weeks before on the Higgs discovery
[17:04] <nick_> "He're 2.3 billion of our earth dollars, go steal someone elses women."
[17:04] <Martian_Lander> xD
[17:04] <SamSilver> enough with the anal probing
[17:06] <Martian_Lander> ROFL
[17:06] <Martian_Lander> np: Jessie J feat BoB - Price Tag
[17:06] <costyn> you can put a rover on mars with a skycrane but can't get their sound to autolevel? :)
[17:06] <radim_OM2AMR> :-D
[17:08] <nigelvh> "Can you sum up how awesome these pictures are?"
[17:08] <nigelvh> My answer: super awesome.
[17:08] <Martian_Lander> XD
[17:09] <Martian_Lander> ohhhh that one woman on the radio morningshow said something like
[17:09] <Martian_Lander> "Mars looks like that structured wallpaper"

[17:16] <eroomde> i cannot wait to build some cool shit
[17:16] <costyn> is inspirational, isn't it
[17:17] <fsphil> I feel like I should write some code worthy of Mars
[17:17] <Martian_Lander> don't say you want to build a Mars Probe
[17:17] <Martian_Lander> XD
[17:17] <fsphil> printf("Hello, Other World!\n");
[17:17] <nigelvh> hahaha
[17:17] <radim_OM2AMR> Martian_Lander should be the first :-)
[17:17] <Martian_Lander> XD
[17:18] <Martian_Lander> yea xD
[17:18] <Martian_Lander> first of all I need to get the balloon probe done
[17:18] <Martian_Lander> and then a river probe maybe
[17:18] <Martian_Lander> but before that I have to pass molecular physics
[17:18] <fsphil> combine the two
[17:18] <Martian_Lander> xD
[17:18] <nigelvh> if($onmars){ $awesomeness++; }else{ $dead = 1 };
[17:19] <Martian_Lander> XD
[17:19] <staylo_> I like how all the news sites are showing images from the lander that are clearly photos of an LCD screen. All they need to do now is lose the originals and it's a real moon landing event :)
[17:19] <Martian_Lander> yea
[17:19] <Martian_Lander> IIRC the original was like that
[17:20] <Martian_Lander> i.e. the video from Apollo 11 on the surface was filmed off a TV screen for some reason
[17:20] <fsphil> different tv formats
[17:20] <Martian_Lander> yeah
[17:20] <Martian_Lander> the feed from the moon didn't match the public TV standards
[17:20] <nigelvh> "they're all digital. There are no 'originals'. It's all a lie!"
[17:20] <fsphil> exactly
[17:21] <Martian_Lander> and then Bean broke it
[17:21] <Martian_Lander> xD
[17:21] <Martian_Lander> you know what I mean?
[17:21] <fsphil> that they had live images from the moon in 1969 was pretty impressive :)
[17:21] <Martian_Lander> yea
[17:21] <Martian_Lander> On Apollo 12, Al Bean panned their colour camera around
[17:22] <Martian_Lander> and then he hit the sun in the viewfield
[17:22] <Martian_Lander> and the camera failed
[17:22] <nigelvh> The moon is much closer. Easier to manage the signal required for live video.
[17:22] <costyn> Martian_Lander: I didn't know that :)
[17:22] <fsphil> I'm not comparing it to mars, I mean just with the TV tech they had in 1969
[17:22] <nigelvh> Yep. Old tube detectors.
[17:22] <radim_OM2AMR> nigel_vh you mean something like that ? :-D http://www.stream.cz/uservideo/554798-jak-to-bylo-s-tim-pristanim-na-mesici

[17:24] <eroomde> live video would be a thing
[17:24] <eroomde> from an orbiter probably easier
[17:24] <eroomde> eg mro video
[17:25] <eroomde> so much engineering data
[17:25] <fsphil> I don't believe the camera is fast enough
[17:25] <eroomde> no ideed, it's just a line of piexels i believe
[17:25] <eroomde> that is skewed across the thing it wants to photo
[17:25] <eroomde> so this wouldn;t work on mro or anything
[17:26] <eroomde> slewed*
[17:26] <nigelvh> I think one of the cameras on the mast can do hi-res video, but it's not up yet.
[17:31] <eroomde> awesomeness
[17:33] <Martian_Lander> hi daveake
[17:34] <daveake> It's a message from Mars
[17:34] <daveake> When's your launch then?
[17:35] <daveake> You realise it only took 8 months to get from Earth to Mars? You could have launched in that time :)
[17:35] <Martian_Lander> xD yea
[17:35] <Martian_Lander> today I checked out my board again
[17:35] <Martian_Lander> first of all it didn't work at all
[17:36] <Martian_Lander> then I noticed the mess of wires
[17:36] <Martian_Lander> I pulled everything out and plugged it together again
[17:36] <Martian_Lander> then it somehow worked but I am not satisfied
[17:36] daveake (Dave@daveake.plus.com) left #highaltitude ("Leaving").
[17:36] <nigelvh> Yes, best to be really sure.
[17:36] daveake (~Dave@daveake.plus.com) joined #highaltitude.
[17:36] <Martian_Lander> yeah cause somehow it didn't show lat and long outside, but it had the correct time
[17:36] <Martian_Lander> inside it suddenly showed crazy coordinates
[17:36] <Martian_Lander> like 17°W
[17:36] <daveake> My first one was a mess. I was lucky it worked.
[17:37] <nick_> Martian_Lander: how long were you outside?
[17:37] <Martian_Lander> how do you mean?
[17:37] <nigelvh> It will grab time first, then position will take a bit longer.
[17:37] <Martian_Lander> ah that
[17:37] <Martian_Lander> yeah more than 10 minutes
[17:37] <nigelvh> Oh, it should have it by then.
[17:37] <Martian_Lander> it had the right UTC time after the fourth string
[17:38] <Martian_Lander> that was about 40 seconds into the run
[17:39] <radim_OM2AMR> I had similar problem with my Venus638FLPx
[17:39] <radim_OM2AMR> then I observed, that active antenna work well only with some grounding :-(
[17:39] <Martian_Lander> grounding?
[17:40] <Martian_Lander> yea but another problem was the navmode
[17:40] <Martian_Lander> it showed 6, as for airborne
[17:40] <Martian_Lander> but it sometimes jumped to 25 or so
[17:40] <radim_OM2AMR> Martian_Lander: see http://www.youtube.com/watch?v=g-JcQiQnvDw&feature=plcp
[17:41] <Martian_Lander> ahh
[17:41] <Martian_Lander> that you mean
[17:41] <Martian_Lander> :)
[17:41] <Martian_Lander> what was the big capacitor for?
[17:42] <radim_OM2AMR> 0.1F capacitor for memory backup
[17:42] <radim_OM2AMR> instead of backup battery
[17:42] <Martian_Lander> ah
[17:43] <radim_OM2AMR> With the capacitor I can achieve warm-start -> quic fix
[17:43] <radim_OM2AMR> of course, when it's not discharged :-)
[17:43] <Martian_Lander> cool :)
[17:44] <radim_OM2AMR> For the upcoming flight we will fly with Venus, but ublox from Upu is on it's way to me ;-)
[17:45] <daveake> How long does the 0.1F keep the memory going for?
[17:45] <nigelvh> I would expect quite a while
[17:45] <daveake> So would I
[17:45] <radim_OM2AMR> daveake I did'nt make such test yet
[17:45] <daveake> ok
[17:45] <radim_OM2AMR> couple of minutes I mean
[17:45] <daveake> Why that rather than a battery?
[17:45] <daveake> The coin ones don't weigh much
[17:46] <nigelvh> Cost or recharge?
[17:46] <nigelvh> rather than replace.
[17:46] <radim_OM2AMR> hmm, good question, daveake.
[17:46] <nigelvh> Though with a coin cell, you'd probably get enough flights to lose it before the cell died.
[17:47] <daveake> I've never checked, but I'd have thought so
[17:47] <daveake> Though with some development times it might not last till the first launch ...
[17:47] <radim_OM2AMR> that capacitor should fix sudden reboots of arduino, if any
[17:48] <daveake> Good for those
[17:48] <radim_OM2AMR> or short power supply fails
[17:48] <nigelvh> If it's on the main rails rather than just the memory support pin on the GPS.
[17:49] <Martian_Lander> radim_OM2AMR, is that the real Slovakian Army suit?

[19:27] <Upu> it has been requested
[19:27] <Merv> Oh I see we should of put the current date in as the start date to allow us to test it
[19:27] <Upu> can do

[19:48] <radim_OM2AMR> Merv, I have some way to simulate GPS data with "balloon" track, you ca see STS-1 in tracker with simulation
[19:48] <jcoxon> Merv, what version of dl-fldigi
[19:48] <jcoxon> the old version did it
[19:48] <jcoxon> but its fixed in the newer versions
[19:48] <Merv> also we entered 450Hz in the payload document but when you autoconfigure the flight HAM-1 it sets the bandwidth to 23Hz ?
[19:49] <jcoxon> again
[19:49] <jcoxon> old version of dl-fldigi
[19:49] <jcoxon> its because 450 is a non-standard shift
[19:50] <Merv> OK i had a feeling that may be the case re the 450Hz.
[19:50] <Merv> Thanks
[19:51] <Merv> also will check the fldigi version. It hammens on my Windows version and also Peter Browne's Mac version

[20:02] <DanielRichman> by "all the beta builds will break" I mean "we'll release the fixed version immediately"
[20:02] <DanielRichman> so you can continue to use the beta build if you want, in the knowledge that that will happen
[20:04] <Merv> OK so it sounds like I should stick with what software I have for the time being and just read off the height from the received gps data in the window
[20:05] <Merv> Thanks Daniel I look forward to the gold plated release with olympic rings attached

[20:16] <Martian_Lander> yea :)
[20:16] <Martian_Lander> it's strange how they had problems on the start
[20:16] <Martian_Lander> like that the one guy had a red pullover and the other had a yellow one
[20:16] <Martian_Lander> the Prague government thought that they wanted to make fun of the tensions between the USSR and China
[20:17] <Martian_Lander> so the production was banned

[21:21] <Randomskk> I'm wondering how much extra battery capacity I can get this thing to lift
[21:21] <Randomskk> and perhaps how much it's worth it given the extra battery weight
[21:21] <Randomskk> they estimate 10 to 15min flight time otherwise which is a bit pants, but it can carry 250g cameras with no ill effect so it seems reasonable that it should be able to heft a reasonable amount of battery

[21:56] <DrLuke> just a quick question, how do I determine how much helium is in a balloon?
[21:57] <DrLuke> could I just use one of those scales with a hook and see how much lift it generates?
[21:57] <SpeedEvil> yes
[21:58] <SpeedEvil> that gives a pretty accurate measure

[22:03] <Randomskk> DrLuke: that's usually the way.
[22:03] <DrLuke> ok thanks
[22:03] <Randomskk> one alternative is to prepare a 'ballast bag' with a pre-measured weight
[22:04] <DrLuke> ah
[22:04] <Randomskk> (based on the calculate - http://cusf.co.uk/calc )
[22:04] <Randomskk> (equal to the "neck lift" on that)
[22:04] <Randomskk> then, attach this bag to your balloon (near the end of filling)
[22:04] <DrLuke> also, is there anything special to watch out when knotting it?
[22:04] <Randomskk> and fill until the balloon is just neutrally bouyant
[22:04] <Randomskk> i.e. floating at the same level
[22:04] <Randomskk> at which point the neck lift is equal to the weight in that bag, and you're set to attach your payload and release
[22:04] <Randomskk> which is the easiest method compared to reading a scale -- hard especially in windy conditions
[22:04] <DrLuke> how do I attach the payload to the neck
[22:05] <Randomskk> string and knots
[22:05] <Randomskk> with knotting the balloon -- don't knot it
[22:05] <DrLuke> uh
[22:05] <Randomskk> typically we would cable tie the neck shut in one or two places, fold the neck over to form a loop, cable tie the loop shut, pass some string through the loop that knots to the loop and to the payload
[22:06] <Randomskk> then duct tape the entire neck up, being especially careful to cover up the sharp ends of the cut cable ties
[22:06] <DrLuke> ah
[22:06] <Randomskk> knotting would probably work, but would be hard, less reliable, and harder to attach a payload to
[22:06] <DrLuke> so basically you create an easy hook to attach the payload to
[22:06] <Randomskk> yea
[22:06] <DrLuke> quite brilliant I must say
[22:07] <Randomskk> I'm sure you'd do much the same by yourself if you found yourself trying to attach a payload to a balloon :P
[22:08] <DrLuke> I would be terrified of accidentally letting go while doing my stuff :P
[22:08] <DrLuke> wait, how do you attach that calibrating weight while filling up?
[22:08] <Randomskk> generally just loop it onto the filling tube
[22:09] <DrLuke> ah
[22:09] <Randomskk> (though you do have to account for the filling tube's weight in the calculations -- or allow that to be your little bit extra)
[22:09] <Randomskk> we/I typically use a filling tube that is L shaped so it's easy to hang stuff off it
[22:09] <DrLuke> do you have a picture of it maybe?
[22:11] <Randomskk> http://www.flickr.com/photos/cuspaceflight/5866515279/in/set-72157626912673027
[22:11] <Randomskk> you can see the PVC pipe
[22:11] <Randomskk> just hidden by someone's hand
[22:11] <Randomskk> and also the hose that's feeding it
[22:11] <DrLuke> ah
[22:11] <Randomskk> and the cable ties and duct tape (temporarily) holding the balloon to the filling tube
[22:12] <DrLuke> you just cable tie the neck to the pipe
[22:12] <DrLuke> nice
[22:12] <Randomskk> to hold it on for filling, yea (also duct tape!)
[22:12] <Randomskk> the duct tape is probably more important
[22:12] <DrLuke> it holds everything together
[22:12] <DrLuke> :P
[22:12] <Randomskk> http://www.flickr.com/photos/cuspaceflight/5867068398/sizes/o/in/set-72157626912673027/ (warning: big image)
[22:12] <Randomskk> if you look at that you can see the plastic pipe filling tube too
[22:12] <Randomskk> and even me, in the background, behind the guy holding the balloon (!)
[22:13] <DrLuke> hehe
[22:13] <DrLuke> how do you attach the hose to the pvc, more duct tape?
[22:14] <Randomskk> you know I can't remember. it probably is duct tape
[22:14] <Randomskk> it's lowish pressure gas, duct tape is fine
[22:14] <DrLuke> ok
[22:15] <DrLuke> I'll use 4 layers just to make sure then

[22:17] <Randomskk> you're just jealous you don't have any real sports nigelvh :P
[22:17] <nigelvh> I've got ping pong. I'm happy with that.
[22:17] <Laurenceb_> that balloon looks a bit rude
[22:17] <Randomskk> DrLuke: hehe, I look forward to hearing how it goes
[22:17] <Randomskk> Laurenceb_: you quickly get over the fact that sounding balloons have a nipple at the top
[22:17] <Laurenceb_> :P
[22:17] <DrLuke> haha
[22:18] <Randomskk> like, at age 12
[22:18] <Randomskk> ....maybe more like 14
[22:18] <nigelvh> And you never get over the fact that women have them.
[22:20] <Randomskk> I don't know about your women
[22:20] <Martian_Lander> may I say ROFL?
[22:20] <gonzo_> men never get over the amusement, they just think that they should pretend they have
[22:20] <Randomskk> but over here nipples at the top are a bit unusual
[22:20] <nigelvh> Well, they're on the top half.
[22:20] <Martian_Lander> ROFL
[22:20] <gonzo_> depends if they are lying down
[22:20] <gonzo_> or pushed up with loads of padding
[22:20] <nigelvh> And what side they're lying on.
[22:21] <gonzo_> hopefully, mine!
[22:21] <nigelvh> Exactly.
[22:21] <nigelvh> In summary balloon nipples, who cares. Woman nipples. Oh yeah.
[22:21] <gonzo_> balloon = giggle
[22:22] <Randomskk> hmm. anyone know if I'm likely to get away with using superglue to bond expanded polystyrene?
[22:23] <nigelvh> Excellent question. Have you tried it?
[22:23] <Randomskk> I'm guessing it'l either work or dissolve the polystyrene
[22:23] <Randomskk> and, no
[22:23] <nigelvh> Sounds like an experiment in potentia.
[22:24] <Randomskk> but I have a thing I would very much enjoy sticking together sooner rather than later and do not much fancy spending a sum of money on the recommended glue
[22:24] <Laurenceb_> no
[22:24] <Randomskk> and superglue is on the list of possible glues.
[22:24] <Laurenceb_> you need special superglue
[22:24] <Laurenceb_> with different solvent or something
[22:24] <Laurenceb_> i forget
[22:24] <Laurenceb_> foam safe CA
[22:24] <Randomskk> :(
[22:24] <nigelvh> You could be the world's premier knowledge source on superglue and polystyrene.
[22:24] <Laurenceb_> epoxy works
[22:24] <Laurenceb_> i am a glue expert
[22:24] <DrLuke> I just remembered: I need a long stick
[22:25] <Randomskk> glues I have available include UHU, a hard plastics glue and superglue
[22:25] <Laurenceb_> not by choice
[22:25] <Laurenceb_> by necessity
[22:25] <Randomskk> I don't think the hard plastics glue will work very well
[22:25] <Laurenceb_> hmm
[22:25] <Randomskk> on account of expanded polystyrene not being a hard plastic
[22:25] <Laurenceb_> normal UHU dissolves superclue
[22:25] <Randomskk> ideal contact cement would be nice
[22:25] <Randomskk> and once I had one
[22:25] <Randomskk> but not any more
[22:25] <Randomskk> not got any epoxy handy either or I'd probably use that
[22:25] <Laurenceb_> yeah its a pita to glue
[22:25] <Randomskk> maybe I should just get some epoxy
[22:25] <Randomskk> apparently the recommended glue works nicely
[22:25] <Laurenceb_> epoxy is the easiest thing to obtain that works
[22:26] <Randomskk> but it's like £16 for a tube that's way bigger than I need and I can only find it on amazon
[22:26] <Randomskk> mm.
[22:26] <Laurenceb_> foam safe CA
[22:26] <Randomskk> if I'm getting foam safe CA it seems epoxy would be easier and just as good?
[22:27] <Randomskk> this is my quadshot incidentally
[22:27] <Randomskk> http://wiki.thequadshot.com/wiki/Assembly_Manual
[22:28] <Laurenceb_> holy shit
[22:28] <Laurenceb_> i hadnt come across that before
[22:28] <Laurenceb_> is it opensource?
[22:28] <Randomskk> yea
[22:28] <Randomskk> paparazzi
[22:28] <Randomskk> only just released
[22:28] <Randomskk> though I backed it on kickstarter about a year ago
[22:28] <Randomskk> and they just shipped
[22:29] <Randomskk> the hardware is I think open source (?) but it's the Lisa/M and varients
[22:29] <Randomskk> the software is paparazzi
[22:29] <Laurenceb_> ah
[22:29] <Randomskk> the flight hardware you can buy as a kit sans electronics if desired
[22:29] <Laurenceb_> looks like a complex control problem
[22:29] <Randomskk> they also have this 'mocha' model which is all pre-assembled and comes with a radio tx
[22:29] <Randomskk> and also was cheaper than the one I got >_>
[22:29] <Laurenceb_> yeah latest paparazzi looks very good
[22:30] <Randomskk> but I get a better microcontroller, with actual connectors for attaching my own stuff
[22:30] <Randomskk> curiously they ship CA in the mocha kit
[22:30] <Randomskk> I mean I'm tempted to use the CA if it'd work just on account of having loads and not having anything else and wanting to assemble it, but
[22:30] <Randomskk> that seems like a foolish decision probably

[22:39] <DrLuke> oh
[22:39] <DrLuke> true
[22:39] <Randomskk> it can be done and all, though, but it's more work than alternatives
[22:39] <Randomskk> harder to interface it to radios and such
[22:39] <DrLuke> not really
[22:39] <DrLuke> just use the UART
[22:40] <Randomskk> go for it
[22:40] <nigelvh> I've never had any heat issues. I use an arduino and inside the box rarely drops below freezing.
[22:40] <Randomskk> nigelvh: the rpi puts out a ton more heat
[22:40] <Randomskk> though the whole thing depends a lot on insulation and the rest of it of course
[22:40] <nigelvh> Exactly
[22:40] <Randomskk> oh, I see what you mean. yes.
[22:40] <nigelvh> Point is DrLuke made it sound like he was worried about not having enough.
[22:40] <DrLuke> well, I can save some weight on the insulation then
[22:41] <DrLuke> then again I need more weight for all the power consumption...
[22:41] <DrLuke> AVR it is!
[22:41] <DrLuke> atleast for the first flight :P
[22:41] <nigelvh> AVR will be simple and you shouldn't have any issues.
[22:42] <DrLuke> yeah
[22:42] <nigelvh> Anyway, home time. Chat with you all later.
[22:42] <DrLuke> I'll just put in a 50W resistor I recently got as an emergency heater
[22:42] <DrLuke> just in case
[22:43] <DrLuke> later
