[00:06] <DanielRichman> jonsowman: that script; maybe a CFLAGS="-O2 -march"
[00:07] <jonsowman> oh?
[00:07] <DanielRichman> you can prepend it to the ./configure
[00:07] <DanielRichman> CFLAGS="-O2 -march" ./configure
[00:07] <DanielRichman> it compiles with -O2 by default
[00:07] <DanielRichman> however just specifying CFLAGS="-march" overrides this default
[00:08] <jonsowman> what does -march do?
[00:08] <DanielRichman> whoops; meant to be -march=native
[00:08] <DanielRichman> enables everything the local processor can support. I don't know if it has any effect :P
[00:09] <jonsowman> oo okay
[00:09] <DanielRichman> perhaps I should benchmark this thing
[00:09] <jonsowman> will do that :)
[00:09] <DanielRichman> jonsowman: I'll compile a with/without
[00:09] <jonsowman> thanks :)
[00:09] <jonsowman> i threw that script together quite quickly when i was switching all my servers to cherokee
[00:09] <jonsowman> just to save myself time
[00:09] <DanielRichman> hehe

[00:14] <jonsowman> right, better be off
[00:14] <DanielRichman> bye
[00:14] <jonsowman> catch you later DanielRichman :)
[00:14] <DanielRichman> probably quite a bit later, I'm not planning on waking up early
[00:15] <Randomskk> ugh my parents are trying to get me to get up early and take this boy out more tomorrow a.n.
[00:15] <Randomskk> a.m., all I want to do is stay home and hack on stuff
[00:15] <Randomskk> I have so much stuff to hack on
[00:15] <Randomskk> jonsowman: gone yet?
[00:15] <Randomskk> apparently, oh well
[00:16] <fsphil|t60> is there a standard way of storing fixed point numbers as integers?
[00:16] <fsphil|t60> before I go re-inventing the wheel
[00:16] <Randomskk> what?
[00:16] <DanielRichman> jonsowman: lines 27 and 40 are dangerous in that script
[00:17] <DanielRichman> 27 if you have spaces in pwd
[00:17] <Randomskk> oh, sorry, in my sleep dep state I read fixed as floating
[00:17] <Randomskk> lol they are rather
[00:17] <Randomskk> well. does it escape them
[00:17] <Randomskk> no. excellent.
[00:18] <DanielRichman> I mean they're fine for someone who's read the script, first
[00:18] <Randomskk> well not really
[00:18] <Randomskk> it's subtle
[00:18] <Randomskk> I mean, subtle that it is dangerous
[00:18] <Randomskk> but with a space in pwd it will potentially delete a directory higher up and totally unrelated
[00:19] <DanielRichman> hmm well only if you had two directories
[00:19] <DanielRichman> ie pwd is /home/daniel/reallyimportantstuff\ notactually
[00:19] <DanielRichman> and another folder /home/daneil/reallyimportantstuff
[00:19] <Randomskk> yea

[00:25] <Randomskk> DanielRichman: fair enough

[08:53] <juxta> hi all
[08:55] Hiena (~Hiena@81.93.195.181.datatrans.hu) joined #highaltitude.
[08:56] <m1x10> juxta have you ever used HardwareSerial in arduino ?
[08:56] <juxta> m1x10, yep
[08:57] <m1x10> can you show me a reference
[08:57] <m1x10> ?
[08:57] <m1x10> googling it does not give me something
[08:57] <m1x10> strange though
[09:00] <juxta> m1x10, how do you mean?
[09:00] <m1x10> a ref of how to use it
[09:01] <m1x10> i was looking for it late at night and didnt find some usage
[09:04] <m1x10> hardware serial is the usual "Serial.print" we do ?
[09:04] <juxta> you're right, I dont see it documented on the arduino language reference
[09:05] <juxta> bbut yes, Serial.read(), .write() etc
[09:05] <m1x10> but can read/write work the same time with print?
[09:06] <m1x10> when i upload the program is uses tx/rx.. so if I use the same wouldnt that cause a problem?
[09:06] <m1x10> im confused
[09:07] <juxta> probably, yes
[09:07] <m1x10> I started using NewSoftSerial without a reason. Just because I sew it in forums.
[09:07] <juxta> it's tricky if you want to use the UART (hardware serial) for uploading the program too
[09:08] <m1x10> you have to take the wires out of the pins i think
[09:08] <juxta> yes
[09:08] <juxta> you would need to remove the gps while uploading
[09:08] <m1x10> bah !
[09:08] <m1x10> dilemma
[09:08] <juxta> you could use an ICSP programmer and not worry about that though
[09:09] <m1x10> uart would have much more capabilities than SoftSerial
[09:09] <m1x10> how to use the ICSP programmer?
[09:09] <m1x10> with a programmer board?
[09:11] <m1x10> ok, I look for it myself. thx for the solution.
[09:13] <juxta> yeah, with a programmer m1x10
[09:16] <fsphil> yikes, it's August already
[09:17] <fsphil> and the noaa server is still not wokring
[09:17] <fsphil> +r
[09:18] <m1x10> :(
[09:22] <juxta> fsphil, are you familiar with tinygps at all?
[09:22] <fsphil> I looked over the source once, but I haven't used it
[09:23] <juxta> hmm
[09:23] <juxta> I've modified it to parse GPVTG sentences but it's not working for some reason
[09:24] <fsphil> is the source up somewhere?
[09:24] <fsphil> I might be able to spot something
[09:25] <juxta> let me chuck it up, 2 secs
[09:28] <juxta> have popped them up here: http://pastebin.com/0AAjgy0H, http://pastebin.com/NLu11Hu5
[09:28] <fsphil> how far does it get?
[09:29] <juxta> the code runs fine, but it doesnt return true when i encode a GPVTG string
[09:30] <juxta> & if I query the object it doesnt return the speed (which is all I want from the string)
[09:32] <fsphil> does the GPVTG line have a checksum?
[09:34] <juxta> yeah
[09:35] <juxta> this is a sample line: $GPVTG,224.03,T,,M,0.874,N,1.619,K,A*3E
[09:41] <fsphil> the strings are passed in with ::encode() ?
[09:42] <juxta> fsphil, yeah, 1 char at a time
[09:47] <fsphil> nothing obvious yet, I'm trying to compile it
[09:52] SpeedEvil (~user@tor/regular/SpeedEvil) left irc: Ping timeout: 276 seconds
[09:54] <juxta> hmm
[09:54] <juxta> fsphil, here's another mod I just came across
[09:54] <juxta> to enable GSA sentences
[09:54] <juxta> http://www.roguerobotics.com/wikidocs/code/arduino_tinygps_satellite_count_mod
[09:54] <juxta> very similar to what I did, can't see where I went wrong
[09:56] <fsphil> ah ha
[09:56] <fsphil> _sentence_id = byte ... 300 is too big
[09:57] <juxta> ahh
[09:57] <juxta> there it is ;)
[09:57] <juxta> thanks a bunch fsphil
[10:01] <fsphil> was that it?
[10:02] <juxta> let me just test it out
[10:02] <juxta> 2 secs
[10:03] <m1x10> juxta, I think you can get the num of active sats from GGA's 7th field
[10:03] <juxta> i'm trying to get speed m1x10 :)
[10:04] <juxta> fsphil, hm, no. still doesnt work.
[10:04] <juxta> come to think of it that wouldnt stop encode() from returning true
[10:04] <m1x10> ah lol. ok
[10:07] SpeedEvil (~user@tor/regular/SpeedEvil) joined #highaltitude.
[10:16] <fsphil> it's reading the speed ok

[10:21] <juxta> ahh
[10:23] <juxta> that fixed it - you're the man fsphil! :)
[10:24] <fsphil> aah I love the smell of bug fixing in the morning
[10:25] <juxta> hehe
[10:26] <juxta> thanks a bunch for that!

[11:01] <m1x10> oh
[11:01] <timbobel> although i am afraid its going to land in the sea..
[11:01] <m1x10> what did u changed?
[11:01] <m1x10> show me link
[11:03] <timbobel> i forgot the charger for the yaesu
[11:03] <timbobel> im in the car
[11:03] <timbobel> how long will it last, fully loaded
[11:04] <m1x10> :)
[11:04] <m1x10> u r chasing now?
[11:04] <sbasuita> timbobel: we ddidn't have a charger for our 817 and it lasted
[11:04] <sbasuita> even did some repeater work
[11:04] <Randomskk> should last the whole flight if it's just receiving and was fully charged
[11:04] <Randomskk> there you go then
[11:04] <m1x10> so, we got a flight right now!?!? m1x10 wake up !

[12:22] <juxta> ah right
[12:23] <juxta> I hope it clears the water!
[12:23] <fsphil> if the decent rate keeps slowing, it *might*
[12:24] <juxta> yeah, looks a bit hairy
[12:24] <timbobel> currently the tyco sirfIII hasnt got a lock
[12:24] <timbobel> its going on the falcom
[12:24] <timbobel> F is falcom
[12:24] <timbobel> T is tyco=vicotech
[12:24] <juxta> timbobel, where abouts are you?
[12:26] <juxta> eek, still falling pretty fast, is the altitude accurate?
[12:28] <fsphil> loss of signal?
[12:31] <juxta> i think it's in the drink
[12:32] <juxta> good thing timbobel has a 'red rubber boat' :P
[12:32] <fsphil> a water recovery would be awesome!
[12:33] <juxta> certainly would be
[12:33] <timbobel> i received an SMS with the coordinates
[12:33] <timbobel> i have the rubber boat, really
[12:33] <timbobel> with pump and paddles
[12:33] <timbobel> not joking
[12:33] <fsphil> :D
[12:34] <timbobel> now going to a small harbor to see if someone wants to earn some cash
[12:34] <jonsowman> haha that is excellent timbobel
[12:34] <juxta> awesome, haha
[12:34] <timbobel> keep u posted
[12:34] <jonsowman> :D
[12:34] <timbobel> i received sms
[12:34] <timbobel> SAID
[12:34] <jonsowman> good work
[12:34] <juxta> how far out in the water do you expect it is timbobel?

[12:35] <jonsowman> someone knock a tracker up for the boat
[12:35] <jonsowman> chase boat can be real this time
[12:35] <jonsowman> :D

[12:39] <fsphil> jonsowman, not a peep
[12:39] <jonsowman> ah shame
[12:39] <juxta> that would be pretty impressive if you did
[12:39] <DUTCH-MILL> Hi @all
[12:39] <jonsowman> that would've been cool
[12:40] <jonsowman> that thing went down pretty quick didn't it
[12:40] <jonsowman> 14m/s
[12:40] <fsphil> would have been - I think I'd need to have been up the mountain here to have any hope
[12:40] <fsphil> thanks for tracking today DUTCH-MILL
[12:40] <jonsowman> mm yeh it's a pretty long way
[12:40] <sbasuita> DUTCH-MILL: timbobel was wondering who you are ;)
[12:40] <fsphil> I wonder if the parachute got tangled, even a small chute should have slowed it down more
[12:40] <jonsowman> definitely
[12:40] <juxta> yeah that was quite fast
[12:40] <DUTCH-MILL> No problem lost signal @6000m
[12:40] <sbasuita> jonsowman: i think it was about 30m/s at one point
[12:41] <juxta> hopefully it floats for a good while
[12:41] <DUTCH-MILL> My name is Klaas Dolman
[12:41] <juxta> and doesnt drift too much
[12:41] <jonsowman> sbasuita: whoa
[12:41] <jonsowman> juxta: i think he said he was designing the payload packaging for a water landing
[12:42] <juxta> oh hi Klaas, good to see you got involved and helped timbobel out - I think I passed your details on to him a while ago :)
[12:42] <jonsowman> so hopefully it'll be fine
[12:42] <juxta> oh great
[12:42] <jonsowman> sucks that the noaa server is down
[12:42] <jonsowman> it's been terrible the last few days
[12:42] <juxta> still?! :O
[12:42] <jonsowman> it came back up for about 12 hours
[12:42] <juxta> ah right
[12:42] <jonsowman> currently down, since yday 9am ish
[12:42] <juxta> no official word?
[12:42] <jonsowman> nope I trawled through their server status pages
[12:43] <jonsowman> sent an email as well
[12:43] <jonsowman> nothing as yet...
[12:43] <SpeedEvil> Just logged in.
[12:43] <SpeedEvil> That looks likely to be damp.
[12:43] <SpeedEvil> Good luck with recovery.
[12:43] <jonsowman> their idea of high availability is interesting
[12:43] <DUTCH-MILL> Lets hope the payload floats...
[12:44] <jonsowman> is this a 404 for anyone else?
[12:44] <jonsowman> http://nomads.ncep.noaa.gov/
[12:44] <juxta> taking a long time to connect here jonsowman
[12:44] <jonsowman> oh dear
[12:44] <juxta> timeout
[12:44] <jonsowman> someone has broken something major
[12:44] <jonsowman> D:
[12:44] <SpeedEvil> I note that google wasn't working a few minutes ago from plusnet
[12:45] <SpeedEvil> along with many other sites
[12:45] <SpeedEvil> In fact only plus.com
[12:45] <jonsowman> broken internets
[12:45] <jonsowman> nah everything else is fine from here
[12:45] <juxta> i imagine they'll be having a busy day then SpeedEvil
[12:47] <SpeedEvil> ?
[12:48] <juxta> their staff
[12:48] <fsphil> DUTCH-MILL, the polystyrene should help keep it floating I hope
[12:48] <SpeedEvil> maybe it was just me
[12:49] <SpeedEvil> Floating - but is the payload that well sealed. Saltwater is bad.
[12:50] <jonsowman> interesting
[12:51] <jonsowman> http://nomad3.ncep.noaa.gov/
[12:51] <jonsowman> seems that all the servers behind the high availability gateway are OK
[12:51] <DanielRichman> am I seeing that page correctly?
[12:52] <DanielRichman> the font gets biggerandbiggerandbiggerandbigger
[12:52] <jonsowman> hehe
[12:52] <jonsowman> it does look like it was made in MS word by a 4 year old
[12:53] <DanielRichman> I think it's caused by the way my browser handles unclosed <h2> tags
[12:53] Action: SpeedEvil tries to remember the tags he learned in 1994 to make a page look just that bad.
[12:54] <m1x10> hah
[12:54] <DanielRichman> making pages look bad only requires one tag: <img>
[12:54] <m1x10> where's timbomel? I fell asleep.
[12:54] <SpeedEvil> http://www.mauve.demon.co.uk/
[12:54] <SpeedEvil> Oooh - wacky.
[12:55] <jonsowman> m1x10: in a boat finding his payload
[12:55] <SpeedEvil> It's still up - despite the fact I have not paid them in >8 years.
[12:55] <jonsowman> afaik
[12:55] <m1x10> jonsowman? you joking ?
[12:55] <m1x10> oh.. now i see the tracker.. LOL !
[12:56] <jonsowman> no I believe he was genuinely planning to get a dinghy and go get it
[12:56] <jonsowman> haha
[12:56] <m1x10> Superb! awesome! Hope only payload is floating and electronics are ok.
[12:56] <m1x10> did falcom gps helped him with high altitude?
[12:56] <DanielRichman> in a dinghy!?
[12:57] <DanielRichman> yeah the falcom seemed to work
[12:57] <m1x10> cool. he had bad dreams with it.
[12:57] <m1x10> :p
[12:57] <DanielRichman> I think it worked better than theotherone
[12:57] <juxta> everyong seems to be hating on the falcom of late - it's been a good module for me!
[12:57] <DanielRichman> which didn't regain a lock (?)
[12:58] <m1x10> maybe the other gps has the ususal limit
[12:58] <juxta> yeah, it was a SIRFIII
[12:58] <m1x10> ooh bad
[12:59] <jonsowman> 12:44 was the last heard from the sirf afaik
[12:59] <m1x10> I will put my SirfIII with sms stuff
[13:01] <m1x10> tracker is not refreshing
[13:01] <fsphil> no new data m1x10
[13:01] <juxta> that's because the payload is busy having a swim m1x10
[13:02] <m1x10> hahahaha
[13:02] <m1x10> why there are two balloons?
[13:02] <m1x10> from 2 gps?
[13:02] <SpeedEvil> 2 payloads, 1 balloon
[13:02] <m1x10> a
[13:02] <m1x10> why 2 payloads?
[13:03] <juxta> 1 payload with 2x GPS I think
[13:04] <m1x10> I hope he found it.
[13:11] <jonsowman> horrible hacky fix to predictor to bypass the HA gateway server
[13:11] <jonsowman> it should now work
[13:11] <jonsowman> but *not* for GFS HD
[13:12] <DanielRichman> what format is GFS? ascii?
[13:13] <jonsowman> think so
[13:14] <jonsowman> http://www.hexoc.com/hab/predict/predict/#!/uuid=bfc298fb8eaeeb17ab7abc3f74856d0d1a61973b
[13:14] <DanielRichman> could we perhaps speed up predictions by parsing and doing the atoi in advance?
[13:14] <jonsowman> that worked
[13:14] <jonsowman> the predictor itself takes no time at all
[13:14] <jonsowman> <1sec
[13:14] <DanielRichman> really? ok
[13:14] <jonsowman> it's getting data from the noaa server that takes time
[13:14] <DanielRichman> no need then
[13:15] <fsphil> do they compress it at all?
[13:15] <DanielRichman> hopefully they atleast gzip it
[13:15] <jonsowman> the python script rewrites the gfs data to a more useful format for the predictor anyway
[13:15] <jonsowman> i'm not sure entirely what it does
[13:15] <jonsowman> have a look through predict.py in the git repo
[13:15] <jonsowman> i'm not a python person (yet)
[13:16] <jonsowman> Randomskk is the person to ask wrt that

[14:18] <Randomskk> hey guys
[14:18] <DUTCH-MILL> Hi
[14:18] <Randomskk> if I was putting an antenna on the roof with the tv and stuff
[14:18] <Randomskk> any suggestions on what kind?
[14:18] <Randomskk> rotator seems out of the question, so a yagi is probably a bad idea
[14:19] <DanielRichman> a balloon tracking antenna?
[14:19] <Randomskk> maybe
[14:19] <Randomskk> well, probably, why not
[14:19] <DanielRichman> or just any antenna?
[14:19] <DanielRichman> what do you want to do with it?
[14:19] <SpeedEvil> I suggest a 50m dish. It's a good multipurpose antenna.
[14:19] <m1x10> 50m ?
[14:20] <Randomskk> it's mostly that I don't generally have roof access, but builders are doing building work and will be up there anyway so can fit whatever
[14:20] <SpeedEvil> Suitable for everything from wifi, to moonbounce, to DXing voyager.
[14:20] <juxta> Randomskk, maybe a discone then
[14:20] <Randomskk> I don't know if a vertical would be great for habbing or not, given as I do have a yagi but nowhere good to put it
[14:20] <Randomskk> if a good vertical would work well for habbing then that'd be a good thing to have
[14:20] <Randomskk> SpeedEvil: DXing voyager would be fun
[14:20] <SpeedEvil> It depends.
[14:21] <fsphil> I use a vertical, and I'm able to decode the cambridge launches - this one:
[14:21] <SpeedEvil> What range are you looking for.
[14:21] <m1x10> SpeedEvil what means DX-ing>
[14:21] <m1x10> ?
[14:21] <SpeedEvil> For - say - 600km - you probably need a yagi
[14:21] <fsphil> Diamond X-50
[14:21] <SpeedEvil> for 200km - a vertical should work just fin.
[14:21] <SpeedEvil> m1x10: Picking up stations at a distance.
[14:22] <m1x10> whats the D stand for?
[14:23] <SpeedEvil> Distance
[14:23] <SpeedEvil> I suppose
[14:23] <Randomskk> x-50 looks good
[14:23] <m1x10> :)
[14:24] <fsphil> doesn't do 6m, if that's a band you think you might want
[14:24] <Randomskk> probably not
[14:24] <Randomskk> tempted to get some form of HF antenna as well though
[14:24] <fsphil> yea
[14:25] <fsphil> hf verticals are *huge* :)
[14:25] <Randomskk> HF antennas generally are quite big
[14:26] <fsphil> sadly
[14:26] <fsphil> I've been considering the vertical for it's small ground area
[14:26] <Randomskk> and expensive
[14:26] <fsphil> that too
[14:26] <fsphil> well, the verticals are expensive but a simple wire out the window can do too
[14:27] <fsphil> the cheapest vertical seems to require manual tuning for each band
[14:29] <Randomskk> not a fan of anything that requires access to the antenna really
[14:29] <fsphil> agreed
[14:31] <Randomskk> still, you reckon the X50 for a 2m/70cm vertical?
[14:32] <fsphil> mine seems to work well

[14:36] <timbobel> there was A SPEEDBOAT
[14:36] <m1x10> timbobel no water inside?
[14:36] <timbobel> that we pulled over
[14:36] <timbobel> no water inside
[14:36] <timbobel> at all
[14:36] <timbobel> one cam with the lens submerged!
[14:36] <timbobel> still m aking pictures
[14:36] <timbobel> first i was like
[14:37] <timbobel> SHIT green pictures only... it were under-water-pics!
[14:37] <timbobel> lenzes were perfect!
[14:37] <m1x10> hahhaa
[14:37] <timbobel> so we retrieved it with the speedboat
[14:37] <timbobel> 4km from the nearest shore
[14:37] <m1x10> falcom worked ok ?
[14:37] <timbobel> we pulled over a speedboat, gave them some cash if we retireved it
[14:37] <timbobel> and we did
[14:37] <timbobel> falcom worked better than the tyco..
[14:37] <m1x10> cool
[14:38] <timbobel> the tyco didnt turn on again below the 23.5km, maybe erronous code.
[14:38] <timbobel> but
[14:38] <m1x10> i want the underwater pics
[14:38] <m1x10> !

[14:38] <DUTCH-MILL> Nice job Tim ----> op naar de volgende
[14:38] <m1x10> i will just shit on the pc to wait for your results timbobel.

[14:39] <fsphil> wow, congratulations!
[14:39] <m1x10> first waterlanding ever? '
[14:40] <fsphil> first retrieval I believe
[14:40] <DanielRichman> I think so
[14:40] <m1x10> cooooooool
[14:40] <fsphil> there's been a few landings before :)
[14:40] <m1x10> im jealous !
[14:40] <DanielRichman> occasionally payloads that have gone in the drink wash up and get returned a few months later, but this is defo. a first
[14:40] <fsphil> that's amazing

[15:01] <m1x10> yes but your are in the air
[15:02] <m1x10> hmm curvature yes
[15:02] <m1x10> right
[15:02] <SpeedEvil> juxta: you don't care
[15:02] <m1x10> some angle
[15:02] <juxta> hey that's a point
[15:02] <SpeedEvil> juxta: distances don't change much.
[15:02] <juxta> yeah
[15:02] <Randomskk> juxta: why gga?
[15:02] <juxta> but I wanted to do it 'right' ;p
[15:02] <Randomskk> why not just rmc or whatever it is, gets you lat/lon/speed?
[15:02] <juxta> Randomskk, so i can switch off all other sentences - RMC doesn't give altitude
[15:02] <Randomskk> it doesn't?
[15:03] <m1x10> y
[15:03] <Randomskk> fair enough then
[15:03] <juxta> nah
[15:03] <m1x10> i was saying that yestarday. they should have made a nmea sentence containing all info together
[15:03] <juxta> GGA doesnt give speed, RMC doesnt give alt - there's no perfect sentence!
[15:03] <m1x10> hehe
[15:03] <juxta> it would be handy
[15:04] <m1x10> i use haversine to measure a whole travel
[15:04] <m1x10> calculating distances for all points
[15:04] <m1x10> adding them and get final distance
[15:04] <Randomskk> tempted by the X-300 instead of a X-50
[15:04] <m1x10> and it is very accurate
[15:04] <Randomskk> it's about twice as long, but you get 9dB instead of 7.2dB gain
[15:04] <Randomskk> not much more cash either
[15:05] <juxta> Randomskk, more gain isn't always a good thing - say if a balloon is near you
[15:05] <juxta> you'll have a much bigger dead spot above you

[15:06] <juxta> oh righto, carry on then (excuse my poor knowledge of UK geography!)
[15:06] <Randomskk> it's a valid point though
[15:06] <Randomskk> not sure what kind of circle of dead spot I'd end up with
[15:07] <Randomskk> but again probably the london thing makes it a non issue
[15:07] <SpeedEvil> Gain isn't so much of an issue when it's overhead
[15:07] <juxta> i've found it's really noticeable even with a 1/4 wave when we get under the balloon
[15:07] <SpeedEvil> as when it's overhead it's at most 35km away
[15:07] <Randomskk> SpeedEvil: yea, but if the high gain antenna has a bigger dead spot, you'll get less reception when it is overhead, right?
[15:07] <SpeedEvil> So it's an issue, but 1/r^2 helps compensate
[15:07] <Randomskk> I guess so
[15:08] <SpeedEvil> the node in theory hurts if you're directly overhead, yes.
[15:08] <Randomskk> but it does seem unlikely I'll end up directly overhead
[15:08] <Randomskk> the 300 is 10ft/3m though
[15:08] <Randomskk> 3m is quite tall
[15:08] <Randomskk> vs 1.5m for the 50
[15:08] <SpeedEvil> If you can cant the antenna 10 degrees by some manner, that'd work
[15:13] <juxta> 3m is quite tall
[15:13] <Randomskk> though it is being mounted on the roof for good with the tv and sky dish antennas
[15:13] <Randomskk> so I don't know if it really matters
[15:14] <juxta> that's coming on close to the height of another storey on your house

[15:14] <Randomskk> there's the X-200 at 8ft or 2.5m, 8dB
[15:14] <Randomskk> costs more than the 50 or 300 though
[15:15] <Randomskk> hmm though the v-2000 is only £7 more, sam eheight, gets 8.4dB and covers 6m
[15:15] <Randomskk> HF verticals are friggin expensive
[15:19] <juxta> SpeedEvil, re this distance/speed calculation - any tips for accounting for the variation in distance between longitudinal degrees at different latitudes etc?
[15:22] <juxta> m1x10, still around?
[15:24] <m1x10> yeah, tell me.
[15:25] <juxta> so distance from point to point is going to be a bit hard to work out - as the distance between long degrees varies greatly at different latitudes
[15:26] <Randomskk> I think maybe I'll just get 2m/70cm for now
[15:26] <m1x10> juxta want to see some haversine calculated distances on google map??
[15:26] <juxta> sure
[15:26] <juxta> I think i'll just do haversine

[15:42] <m1x10> so i keep using haversine
[15:43] <juxta> that's quite good :)
[15:43] <m1x10> but you need to have track very frequenctly
[15:43] <m1x10> if you are on road with corners and stuff
[15:44] <m1x10> for ballooning its not so important
[15:44] <m1x10> (i believe)
[15:44] <m1x10> i measured a 130km road distance from home to holiday place
[15:45] <m1x10> and my car showed 135km
[15:45] <m1x10> while haversine 133km
[15:45] <m1x10> the loosing is from corners
[15:46] <m1x10> the car goes like the road
[15:46] <m1x10> but haversine line goes directly point to point

[15:56] <SpikeUK> Sorry! Been away. timbobel did you get your payload back? Truly?
[15:56] <m1x10> yeah he did
[15:57] <m1x10> all ok
[15:57] <SpikeUK> m1x10 - thanks!
[15:57] <m1x10> I got question. Soldering a typical breadboard wire to my antenna connector is ok? or I need some special 50ohm wire?
[15:58] <m1x10> SpikeUK, he will post the results until the night he said
[15:59] <juxta> m1x10, it's a good idea to use 50ohm coax if you can
[15:59] <m1x10> juxta ok. Do u happen to know how much ohm is those typical wires?
[16:00] <Randomskk> that's not really what it means
[16:00] <juxta> the rating of coax applies to impedence, not to resistance
[16:00] <Randomskk> but are you taking about short wire connections
[16:00] <Randomskk> or long cables
[16:00] <Randomskk> for e.g. connecting the socket to your radio you can use normal wire and it'l be okay
[16:00] <juxta> if it's short you can get probably get away with it
[16:00] <Randomskk> for connecting the antenna to the socket you really should use coax
[16:01] <m1x10> wait one by one !
[16:01] <m1x10> Randomskk I want to do the following.
[16:02] <m1x10> my connector got a 'gold' pin. I want to solder a wire on it. This wire will end on radiomexetrix RF out pin.
[16:02] <Randomskk> long or short though
[16:02] <m1x10> very short
[16:02] <m1x10> 1-3cm
[16:02] <Randomskk> that's fine. normal wire is okay.
[16:03] <m1x10> connector will be very near to radiometrix module
[16:03] <Randomskk> yup.
[16:03] <Randomskk> normal wire's fine.
[16:03] <m1x10> ok thx. thats i want to hear
[16:03] <m1x10> something else
[16:03] <m1x10> if i use a resistor instead of the wire
[16:04] <Randomskk> what
[16:04] <m1x10> a resistor of 0ohm
[16:04] <Randomskk> there shouldn't be any resistors there
[16:04] <Randomskk> oh
[16:04] <Randomskk> that's just a wire
[16:04] <m1x10> y
[16:04] <Randomskk> 0 ohm resistors are just wires
[16:04] <m1x10> i have resistors with just a black line
[16:04] <Randomskk> yes.
[16:04] <Randomskk> they are just wires
[16:04] <m1x10> ok
[16:04] <Randomskk> you may as well use a wire though
[16:04] <m1x10> but in the form of a wire
[16:04] <m1x10> sorry
[16:04] <Randomskk> just use a normal wire to be honest
[16:04] <m1x10> but in the form of a resistor
[16:05] <m1x10> the resistor-like wire
[16:05] <m1x10> fits better and more firmly on the breadboard
[16:05] <Randomskk> okay. go for it
[16:05] <juxta> m1x10, are you soldering your payload together?
[16:06] <m1x10> i finished my aprs/sensor system
[16:06] <m1x10> i just want to attach somehow the connector on it
[16:07] <m1x10> its a compact module
[16:07] <m1x10> consists of arduino protoshield and 2 mini breadboards
[16:07] <m1x10> its very solid
[16:07] <m1x10> i mean things dont get apart
[16:07] <juxta> breadboard means this to me: http://tangentsoft.net/elec/bitmaps/iguana-breadboard.jpg
[16:08] <m1x10> y
[16:08] <juxta> which seems sort of prone to falling apart

[17:05] <juxta> it's a 1PPS output, which I assumed came on with a 3d lock - but it'll keep pulsing even if it loses lock
[17:05] <jcoxon> thats not too much of an issue
[17:05] <juxta> for as long as it thinks it's still got accurate time
[17:05] <jcoxon> but a good point
[17:05] <juxta> no, not really
[17:05] <Randomskk> best to look at the nmea data to see if it has lock I'd have thought

[20:03] <SpikeUK> Tape measure?
[20:03] <Matt_soton> well one of our failed launches (too little heluim) probably beat that...
[20:04] <Lunar_Lander> well it says that the GPS record is used

[20:20] <Randomskk> windows movie maker? :P
[20:20] <Lunar_Lander> :D
[20:21] <timbobel> i extraced the vid with that :)
[20:23] <timbobel> hahahaaaa and yes, i honestly recovered the splashed down module with a 60 miles per hour speedboat
[20:28] <Lunar_Lander> the BallastHalo 5?
[20:29] <timbobel> ;); the HoHoHo I
[20:29] <timbobel> www.hollandshoogte.nl
[20:29] <timbobel> my dutch launch today
[20:33] <Lunar_Lander> cool
[20:33] <Lunar_Lander> and it did end up in the Ijssel?
[20:33] <timbobel> Oh yse.
[20:33] <timbobel> yeah
[20:34] <Lunar_Lander> oh shit
[20:34] <timbobel> i stopped a speedboat
[20:34] <timbobel> in the middle on the dyke we parked
[20:34] <timbobel> i rushed out to get myself that boat
[20:34] <timbobel> and they were willing to go out
[20:34] <timbobel> so yeah
[20:34] <timbobel> that was too cool
[20:34] <Lunar_Lander> yeah
[20:34] <Lunar_Lander> http://hollandshoogte.files.wordpress.com/2010/07/foto1.jpg
[20:35] <Lunar_Lander> your friend?
[20:35] <timbobel> girlfriend yea
[20:35] <Lunar_Lander> dang
[20:35] <Lunar_Lander> didn't read the text
[20:35] <Lunar_Lander> sorry
[20:35] <timbobel> she had the payload on her lap in a sparkfun box
[20:35] <timbobel> i like the little red sparkfun boxes. came in handy today
[20:35] <Lunar_Lander> yea
[20:35] <timbobel> when going on the boat i was noting the coordinates.. no paper.. so i used the box
[20:36] <timbobel> hail to the iphone by the way; i just checked out the GPS on the boat
[20:36] <timbobel> and then related that to the GPS spashdown site
[20:36] <timbobel> and luckily i received an sms at 250m altitude
[20:36] <Lunar_Lander> yeah

[20:40] <SpeedEvil> the stuff to make hydrogen isn't that nasty.
[20:40] <Lunar_Lander> hydrogen in the air is forbidden in Europe
[20:40] <Lunar_Lander> I read that on a website explaining why helium is used
[20:40] <SpeedEvil> umm.
[20:40] <SpeedEvil> I don't recall any regulation as to that effect.
[20:42] <timbobel> realllly??
[20:44] <Lunar_Lander> it was some regulation here in Germany

[21:03] <SpeedEvil> of the ground?
[21:04] <sbasuita> SpeedEvil: yes
[21:04] <SpeedEvil> yeah.
[21:04] <SpeedEvil> I did the numbers once for a spysat.
[21:04] <sbasuita> timbobel: congrats on the recovery - that is seriously cool going ;)
[21:04] <SpeedEvil> Which is sort-of-similar.
[21:05] <SpeedEvil> IIRC a 30cm mirror will give you a pic in 6-8 mins at 30km, if you can keep it pointed.
[21:05] <SpeedEvil> Adding a laser pointer for illumination _vastly_ speeds it up.
[21:05] <SpeedEvil> Oh
[21:05] <timbobel> thanks sbasuita; a lot of thanks of you and daniel, good blog. daniel helped a lot with the T68i phone
[21:05] <SpeedEvil> that was assuming dark skies, and ~1m pixels I think

[21:12] <Lunar_Lander> what are you trying to photograph?
[21:13] <sbasuita> Lunar_Lander: city lights
[21:13] <sbasuita> at night
[21:14] <Lunar_Lander> ah nice
[21:15] <Lunar_Lander> btw optics
[21:15] <Lunar_Lander> http://www.eoss.org/ansrecap/ar_030/recap04d.htm
[21:15] <Lunar_Lander> they had a little solar telescope
[21:15] <SpeedEvil> http://medusa.as.arizona.edu/lbto/AO/AOpressrelease.htm
[21:15] <SpeedEvil> ah - city lights require no optics at all
[21:15] <Lunar_Lander> might be interesting to photograph earth with it too
[21:15] <Lunar_Lander> ahok
[21:15] <SpeedEvil> as they are quite bright enough
[21:15] <Lunar_Lander> yeah
[21:15] <Lunar_Lander> just wanted to bring in the scope ;)
[21:16] <sbasuita> SpeedEvil: by optics i meant an expensive lens
[21:16] <SpeedEvil> yeah
[21:16] <SpeedEvil> I don't think expensive lenses will actually help much
[21:17] <SpeedEvil> You need a light sensitivity several orders of magnitude higher.
[21:17] <sbasuita> yes and a big ass aperture
[21:17] <SpeedEvil> And you can either get that by using a _much_ bigger sensor, with a similar lens, or longer opening.
[21:17] <sbasuita> the issue is the swaying of the balloon
[21:17] <sbasuita> you're limited to a fast shutter
[21:17] <SpeedEvil> You can't improve it enough by going from F/10 to F0.5
[21:17] <SpeedEvil> And you're not getting better than that
[21:18] <sbasuita> hmm
[21:19] <timbobel> first HoHoHo I pics up

[21:21] <timbobel> yes

[21:21] <timbobel> it did noting
[21:22] <timbobel> nothing at all
[21:22] <timbobel> it crashed at around 80kmpu
[21:22] <Lunar_Lander> it did nothing?!
[21:22] <timbobel> nah didnt help
[21:22] <timbobel> trangled etc
[21:23] <Lunar_Lander> diameter`?
[21:25] <Lunar_Lander> wait
[21:25] <Lunar_Lander> question
[21:26] <Lunar_Lander> http://hollandshoogte.wordpress.com/flights/august-2010/dscn0640/
[21:26] <Lunar_Lander> why did you mount the chute like that?
[21:38] <timbobel> how else
[21:38] <timbobel> 36'
[21:38] <timbobel> i have no chute skills
[21:39] <Randomskk> same mounting style as apex 2
[21:39] <Randomskk> notably apex 2's parachute deployed fine, worked until the last km ish, then got tangled and became ineffective, impact velocity was about 10m/s
[21:40] <Randomskk> as far as a night launch goes, non blurred city lights and I'm happy
[21:41] <timbobel> all the pics are up www.hollandshoogte.nl
[21:41] <timbobel> when is there a nightlaunch
[21:41] <timbobel> 10ms is allright
[21:41] <timbobel> i tripled that
[21:41] <timbobel> by the way, is that a record?
[21:41] <Lunar_Lander> I think the best way is still the stretched chute
[21:42] <Lunar_Lander> records are here: http://www.arhab.org/ARHABrecords.htm
[21:42] <timbobel> wow by the way
[21:42] <timbobel> was there a telemetry record set!?!??!
[21:42] <Lunar_Lander> current record is at some 39140 m
[21:42] <timbobel> who cares about height
[21:42] <timbobel> it's all about impact speed

[21:52] <DanielRichman> the arhab.org records are in miles and are massive
[21:52] <Randomskk> 4,572 miles :P
[21:52] <DanielRichman> HF is cheating
[21:52] <Randomskk> massively
[21:53] <Lunar_Lander> is that from an atlantic attempt?
[21:53] <Lunar_Lander> the 4572

[22:00] <m1x10> IM JEALOUS
[22:00] <Lunar_Lander> hi natrium42
[22:01] <m1x10> timbobel did u watch the spycam video?
[22:01] <natrium42> hi
[22:01] <timbobel> oh yes
[22:02] <timbobel> was it a succes
[22:02] <timbobel> oh yes
[22:02] <natrium42> awesome
[22:02] <timbobel> it filled the full 4gb in exactly an hour
[22:02] <natrium42> did iy land in water?
[22:02] <timbobel> so get 8gb, you can film 2 hrs
[22:02] <timbobel> natrium: yes, 4km from shore
[22:02] <m1x10> did u post a scene of it on internet?
[22:02] <timbobel> not yet
[22:02] <Lunar_Lander> did we ever had a splashdown here?
[22:02] <timbobel> im making a small vid
[22:02] <m1x10> can u show me a link to the spycam? I going to buy.
[22:02] <Lunar_Lander> m1x10 I once saw the hovercrafts of the Greek army on TV
[22:03] <timbobel> UKHAS has a lot of unreturned splashes in the northsea
[22:03] <timbobel> but this is the first splash recovery i think
[22:03] <Lunar_Lander> they said that they have them because Greece has so many islands
[22:03] <m1x10> Lunar_Lander, logical.
[22:03] <Lunar_Lander> maybe you can ask the army if you can borrow a hovercraft :)
[22:03] <natrium42> timbobel, how did you recover it?
[22:03] <m1x10> half country is islands and water
[22:03] <timbobel> why does greece have to defend themselves
[22:03] <timbobel> natrium: i pulled someone with a speedboat over
[22:03] <m1x10> my cousin got a speedboat !!
[22:03] <timbobel> and we were skipping over the water about 20km's
[22:04] <timbobel> and then we found it
[22:04] <timbobel> so yes
[22:04] <timbobel> pics are up
[22:04] <natrium42> haha, nice
[22:04] <m1x10> timbobel can u show me a link to the spycam? I going to buy.

[22:04] <m1x10> yes the model i want

[22:05] <natrium42> timbobel, ooh, it landed near that road in the water
[22:05] <natrium42> i have been on it many times
[22:05] <timbobel> natrium: yes
[22:06] <m1x10> timbobel I was for coffee and I was telling my company about your experience.. :)
[22:06] <timbobel> "near" = 4 km, too much for the red rubber boat ( I DID HAVE WITH! )
[22:06] <timbobel> it was super exciting in the car
[22:06] <timbobel> too cool
[22:06] <Lunar_Lander> m1x10 see the ebay link :)?
[22:06] <timbobel> we taped the whole thing im oging to make a nice vid
[22:06] <m1x10> ooooooo yeah
[22:07] <m1x10> thats what i like at most
[22:07] <m1x10> the experience
[22:08] <m1x10> another question
[22:08] <m1x10> when landed your aprs system was still sending data?
[22:08] <timbobel> no
[22:08] <timbobel> last data was on 750 metres
[22:08] <m1x10> why?
[22:09] <timbobel> after that i think the antenna was fckd
[22:09] <timbobel> i did get an SMS at 250 metres
[22:09] <timbobel> the same minute it splashed down, due to my awesome code
[22:09] <m1x10> aah, technical issue then
[22:09] <timbobel> and after the 70km/hour crash
[22:09] <timbobel> IT REBOOTED
[22:09] <timbobel> i have an HOUR of GPS data of the float!!
[22:09] <m1x10> 70km/h?
[22:09] <timbobel> yes
[22:09] <m1x10> no parachute?
[22:09] <timbobel> it hurled down when it came down with 150km/hr
[22:09] <timbobel> yes
[22:09] <timbobel> entangled
[22:10] <m1x10> oh man
[22:10] <m1x10> and if it was going to a head
[22:10] <m1x10> now timbobel behind prison
[22:10] <m1x10> :(
[22:10] <Lunar_Lander> timbobel
[22:11] <Lunar_Lander> did you order your chutes with the balloon modification?
[22:11] <m1x10> there is a solution for entangled parachutes.
[22:11] <m1x10> there is a solution to avoid entangled parachutes.
[22:11] <natrium42> do not use parachutes!
[22:11] <m1x10> haha
[22:11] <m1x10> no natrium42
[22:11] <natrium42> :P
[22:11] <m1x10> dont cause fatalities !
[22:11] <natrium42> bbl, gone fishin
[22:12] <Lunar_Lander> xD
[22:12] <Lunar_Lander> have fun natrium42
[22:12] <m1x10> a practical and easy solution for entangled parachutes is to place a ring
[22:12] <m1x10> then attach any rope of the parachute to the ring
[22:13] <m1x10> when is falls then cannot get mixed up
[22:13] <m1x10> and parachutes open immediately
[22:13] <timbobel> easier said than tested
[22:13] <timbobel> keep-it-simple is important in HABBING
[22:14] <m1x10> agree. but parachute entangling issues may cause severe damage to public.
[22:14] <m1x10> and for safety reasons u must always do something
[22:14] <m1x10> not KISS
[22:15] <m1x10> image your payload being droped in a car window
[22:15] <Lunar_Lander> or a stadium
[22:15] <m1x10> the driver panics and starts hitting pedestrians
[22:15] <Lunar_Lander> or a rail line
[22:15] <m1x10> or even falling to a human
[22:16] <m1x10> 99% can kill
[22:16] <m1x10> you dont KISS for safety reasons
[22:16] <m1x10> thats a rule
[22:16] <m1x10> placing a ring is so easy and simple
[22:17] <m1x10> eventually ur very lucky that the payload was droped in the water
[22:17] <Lunar_Lander> timbobel got my question?

[23:06] <Laurenceb> if it worked why is it shitty?
[23:06] <timbobel> dont get me started
[23:06] <Laurenceb> probably power supply issues, ublox is very particulatr about the power supply in my experience
[23:06] <timbobel> this is the first day it could get a decent lock
[23:07] <timbobel> is that then, my fault, or ublox'es ;) i vote ubloxes.

[23:07] <Laurenceb> well it just requires good practice to be followed with the power supply design
[23:07] <Laurenceb> often with breadboard setups thats far from the case
[23:08] <timbobel> well then
[23:08] <timbobel> its a shitty module for the breadboard
[23:08] <Laurenceb> maybe true, but the performance when its used properly is second to none
[23:08] <timbobel> but today it won points
