[00:56] <juxta_> hi all
[00:56] <natrium42> hey
[00:56] <juxta_> we're in the field getting ready atm
[00:56] <natrium42> cool
[00:58] <juxta_> natrium42: can you clear the tracker for me?
[00:58] <juxta_> i cant access it
[00:58] <juxta_> internet is too slow
[00:58] <natrium42> ok, all of it?
[00:58] <juxta_> yeah
[00:59] <natrium42> done
[00:59] <juxta_> you should start getting packets in from chase-juxta and chase-vk5zsn too
[00:59] <natrium42> yep, they're there
[00:59] <juxta_> excellent :)

[01:55] <natrium42> yeah
[01:56] <natrium42> chase-juxta dropped of for a while, but is back now
[01:57] <juxta_> yeah
[01:57] <juxta_> my net dropped
[01:57] <juxta_> we're progressing slowly :)
[01:57] <natrium42> kk
[01:57] <juxta_> can you keep an eye on spot.projecthorus.org for me and let me know when we show up?
[01:57] <natrium42> ok
[01:58] <juxta_> cheers
[01:58] <natrium42> i could redirect it to the tracker, if you want
[01:58] <natrium42> got a script to do it
[01:59] <natrium42> might be too confusing though as updates will be rare
[01:59] <juxta_> from spot to the tracker?
[01:59] <natrium42> yeah
[02:00] <juxta_> yeah
[02:00] <juxta_> praps leaqve it unless things go wrong
[02:00] <natrium42> k
[02:00] <natrium42> so everything else is progressing well?
[02:00] <juxta_> brb, i need to to disconnect my net to get a usb port

[02:34] <juxta_> we're in the field now drift
[02:34] <Drift> haha
[02:34] <Drift> excellent
[02:34] <juxta_> just filling the balloon :)
[02:35] <Drift> i would be tracking it but ive only got fm uhf radio :(
[02:37] <natrium42> juxta_, btw, got spot locations

[02:38] <juxta_> sweet
[02:38] <juxta_> cheers natrium
[02:43] <juxta_> natrium42, can you do me a fav?
[02:43] <natrium42> sup?
[02:43] <juxta_> can you use burst1a.xls and calc the free lift in grams we need with a 1500 balloon, 1500g payload for 5m/s lift?
[02:43] <natrium42> sure, one sec
[02:44] <natrium42> ooh, there is an online version now

[02:45] <juxta_> too slow here, haha
[02:45] <juxta_> http seems to be a no go :P
[02:47] <juxta_> any luck natrium42?

[02:48] <natrium42> kg
[02:48] <natrium42> free lift
[02:49] <SpeedEvil> Shouldn't that end number be a 4?
[02:49] <natrium42> sure :P
[02:51] <natrium42> ooh, another spot update 5 mins ago
[02:54] <natrium42> juxta_, you're using helium, right?

[03:28] <SpeedEvil> Damn things in walls keeping me awake :/
[03:28] <natrium42> SpeedEvil, get a cat?
[03:28] <SpeedEvil> in walls.
[03:29] <natrium42> meh
[03:29] <Drift> kitten that can fit in walls
[03:29] <SpeedEvil> Or a tiger that can knock them down
[03:35] <juxta_> ok
[03:35] <juxta_> gpot fixc
[03:36] <SpeedEvil> Good luck!
[03:36] <natrium42> altitude is 0?
[03:36] <SpeedEvil> I am not going to see the outcome - well unless it bursts in the next moments - but hope you get it back in one. Are there cameras?
[03:37] <natrium42> oh, it's up
[03:38] <Drift> weeeee
[03:39] Action: natrium42 clears initial locations
[03:42] <Drift> i'm only seeing chase-vk5zsn on the tracker
[03:44] <natrium42> i cleared it, but there were no updates since then
[03:44] <Drift> odd
[03:46] <juxta_> natrium42
[03:46] <juxta_> you'll see me in a sec
[03:46] <natrium42> ok, did you stop listening to the radios?
[03:46] <juxta_> nah, payload lost lock while we're sealing it up

[04:05] <Drift> :)
[04:06] <juxta_> hmm
[04:06] <juxta_> alt is not coming in
[04:06] <juxta_> its stuck at 418m
[04:06] <natrium42> needs more sats
[04:07] <juxta_> hmm
[04:07] <juxta_> maybe
[04:08] <natrium42> 85C nice :P
[04:12] <Drift> nice signal from the radio
[04:13] <Drift> S9 on FM, not that it means much. if only i had SSB
[04:14] <N900evil> you sholuld in princip.le be able to decvode. can you heafr a buzz/clicking
[04:15] <Drift> yeah
[04:15] <N900evil> I howecer don't tgink anyone has written a decoder
[04:16] <Drift> oh well
[04:16] <N900evil> it's lots less sensitive - but ...
[04:18] <natrium42> nearing 8km
[04:19] <natrium42> looks good
[04:19] <Drift> zing
[04:19] <natrium42> ascent a little faster than 5m/s

[05:26] <natrium42> coming down now
[05:27] <natrium42> max alt i see was 29509m

[05:31] <natrium42> about 70km/h now
[05:31] <Drift> when does parachute deploy?

[05:34] <natrium42> you can also watch it in google earth --> http://spacenear.us/tracker/track.kml
[05:35] <natrium42> whoops, buggy location there
[05:35] Action: natrium42 deletes
[05:35] <Drift> i tried earlier but my GE went kaboom
[05:35] <natrium42> ah, weird
[05:35] <Drift> its oldddd
[05:35] <natrium42> get a new one :P
[05:35] <Drift> one day :P
[05:35] <natrium42> XD
[05:36] <natrium42> 50km/h now
[05:40] <natrium42> 40km/h
[05:45] <natrium42> hah, it's near some small airport/fly-in community
[05:46] <Drift> haha oops
[05:46] <natrium42> maybe airport for crop dusters
[05:47] <natrium42> 30km/h
[05:47] <natrium42> chute is working well
[05:48] <Drift> Murray Bridge Airport (ICAO: YMBD) is 5 nautical miles (9 kilometres) northwest of Murray Bridge in South Australia. It is situated on the Palmer Road and is also known as Pallamana Aerodrome[1] or Pallamanna Airfield[2].
[05:48] <Drift> theres a flying school there too
[05:48] <natrium42> ah
[05:50] <natrium42> it's making a nice figure 8
[05:50] <natrium42> or ampersand
[05:51] <natrium42> dunno how they'll recover it, the roads don't seem that nice :P
[05:51] <natrium42> hrm, descent rate is higher :S
[05:52] <natrium42> Pressure (hPa): 666
[05:52] <natrium42> omg
[05:53] <Endeavour> OMG!
[05:53] <Drift> zomggggg
[05:53] <Endeavour> IT BE A NATRIUM42!
[05:53] <natrium42> huhuhu
[05:53] <natrium42> hrm, many trees there
[05:54] <natrium42> it better not land on one
[05:54] <Endeavour> natrium42: I might not make the weather balloon.
[05:54] <Drift> still plenty of time
[05:54] <Endeavour> I'll probably design everything for it.
[05:54] <natrium42> why not?
[05:54] <Endeavour> But I don't really wish to lose that much in electronics.
[05:55] <natrium42> no risk, no gain
[05:55] <Endeavour> Sure.
[05:55] <natrium42> 927m
[05:55] <Endeavour> But ultimately pretty pictures aren't worth the dough. ;)
[05:55] <natrium42> at least it will land near a road
[05:55] <Endeavour> I may build a rocket instead.
[05:55] <Endeavour> Same sensors, no camera.
[05:55] <natrium42> Endeavour, just add a SPOT
[05:55] <Endeavour> What's a SPOT?
[05:55] <natrium42> that thing is pretty safe
[05:55] <natrium42> satellite messenger
[05:56] <natrium42> findmespot.com
[05:56] <natrium42> ok, it landed it seems
[05:56] <natrium42> now we can watch the recovery live :D
[05:57] <Endeavour> Whats going on?
[05:57] <natrium42> topic?
[05:57] <natrium42> http://spacenear.us/tracker
[05:57] <natrium42> a payload just landed
[05:57] <Endeavour> Ah
[05:57] <Endeavour> Cool
[05:58] <natrium42> hehe, it's warming up
[05:58] <Endeavour> In Canadia?
[05:58] <natrium42> temperatures rising
[05:58] <natrium42> aussie land
[05:59] <Endeavour> Ah, yes, indeed.
[05:59] <Endeavour> Just zoomed out.
[05:59] <natrium42> :)
[06:00] <natrium42> i am glad it completed a figure 8
[06:00] <natrium42> just barely
[06:00] <Drift> lol
[06:00] <natrium42> hehe, they stopped at the farmer's house
[06:01] <natrium42> ask for permission etc i guess
[06:01] <Drift> git off my lawn!
[06:01] <natrium42> "finders keepers, losers weepers!"
[06:02] <natrium42> better not
[06:02] <natrium42> here in canada, you can feel pretty safe entering private property
[06:02] <natrium42> in the US, you can get shot...
[06:02] <Drift> not usually too bad in aus i dont think
[06:03] <Drift> having said that i dont usually go venturing onto private property :P
[06:03] <natrium42> yeah, i always ask too
[06:04] <natrium42> ok, they're en route again
[06:05] <Drift> how often do people launch high altitude ballons?
[06:05] <Drift> *balloons
[06:05] <natrium42> there's a launch announcement site --> http://www.arhab.org/ARHABlaunchannouncements.html
[06:05] <natrium42> but it's mostly US launches
[06:06] <Drift> nifty
[06:06] <natrium42> weather services launch them every day :P
[06:06] <Drift> :P
[06:06] <Drift> a balloon fell in my backyard once, stinky latex thing
[06:07] <natrium42> cool
[06:09] <natrium42> now, are they going to drive to it or walk? :P
[06:09] <natrium42> drive, wtf
[06:09] <natrium42> lazy australians!
[06:11] <Drift> :)
[06:12] <natrium42> still no SPOT updates

[06:27] <natrium42> hey jcoxon
[06:27] <natrium42> judging from the tracks, payload has been recovered and they are en route home
[06:28] <jcoxon> morning
[06:28] <jcoxon> the tracker is confusing!
[06:28] <natrium42> yeah
[06:28] <natrium42> maybe the markers need to fade out with time
[06:28] <jcoxon> need to have some thought about chase cars :-p
[06:28] <natrium42> actually i have been playing with removing markers alltogether in the new version
[06:29] <natrium42> only when you near the track with the cursor, will little squares become visible
[06:29] <jcoxon> oh i see, yeah
[06:30] <jcoxon> max altitude?
[06:30] <natrium42> 29509m
[06:30] <jcoxon> maybe you should be able to turn tracks on and off
[06:30] <natrium42> that too
[06:30] <jcoxon> e.g. i'd really like to just see the horus track alone
[06:30] <natrium42> and the polyline should fade out with time
[06:31] <jcoxon> for the payload?
[06:32] <jcoxon> looks like it was a great flight

[06:45] <Drift> lol, just by chance
[06:45] <natrium42> i half-assed it quickly...
[06:45] <Darkside> does anyoe know the times/set frequenies for the BOM balloons?
[06:45] <Darkside> or is the frequency kind of set randomly between 400 and 403
[06:46] <jcoxon> natrium42, hehe good work - i reckon rjharrison and you should merge tracker code
[06:46] <natrium42> :)
[06:46] <natrium42> payload still transmitting XD
[06:46] <jcoxon> wow internal temp stayed nice and toasty

[06:47] <Darkside> also thanks for putting the code online :)
[06:47] <Darkside> it helped with a rtty transmitter i was working on
[06:47] <Drift> darky, are you building a high-alt balloon?
[06:47] <natrium42> so edmoore, what canon you got? :P
[06:48] <edmoore> couple of 540s lying around?
[06:48] <natrium42> cool, spot started working again -- took a while for it to recover
[06:48] <Darkside> Drift: no
[06:48] <Drift> well, do it!
[06:48] <Darkside> its for a uni project
[06:48] <Darkside> lol
[06:48] <natrium42> edmoore, hmm
[06:48] <Darkside> my uni project operates on HF :P
[06:49] <Drift> cool. what exactly is said project?
[06:49] <Darkside> i was gonna test thr transmitter with a tethered balloon vertical
[06:49] <natrium42> edmoore, powershot 540 has no remote capture

[06:49] <Darkside> as i don't havthe horizontal space in my backyard for a 40M dipole, i was gonna set up a vertical, using a balloon :)
[06:50] <Drift> pschulz01, hey, it went well
[06:50] <pschulz01> Is there an altitude plot somewhere?
[06:50] <natrium42> yes, click the google earth link
[06:50] <natrium42> on the tracker
[06:50] <Darkside> does anyone have any info on the BOM balloons?
[06:51] <Darkside> launch times, frequencies, etc?

[06:51] <jcoxon> Darkside, unfortunately not - most people on here are based in the UK or Canada
[06:51] <Darkside> heh
[06:51] <jcoxon> juxta would be the one who knew
[06:52] <Darkside> i thought there wul dbe a few adelaideians, for the horus launch
[06:52] <jcoxon> they are out in the field!
[06:52] <pschulz01> The landing ground looked nice and open.
[06:52] <Darkside> hahaha
[06:52] <natrium42> Drift is an aussie
[06:52] <pschulz01> Still out in the field?
[06:52] <Darkside> natrium42: i know :)
[06:52] <natrium42> pschulz01, you can still track the chase cars
[06:52] <jcoxon> pschulz01, collecting the payload
[06:52] <natrium42> :P
[06:53] <natrium42> actually, you can also track the payload as it sits in the chase car
[06:53] <pschulz01> Excellent :-) Well done..
[06:53] <natrium42> they didn't seem to have turned it off
[06:55] <jcoxon> right some more sleep

[09:17] <MikeMc68> hi
[09:17] <MikeMc68> the launch is off?
[09:19] <adhoc> MikeMc68: which launch
[09:20] <jcoxon> horus was launched
[09:20] <jcoxon> bh4 is postponed for a week
[09:20] <adhoc> ah
[09:20] <adhoc> i watched the tracking on the web page =)
[09:21] <jcoxon> haven't heard back if they recovered pics yet :)
[09:21] <MikeMc68> bh4
[09:22] <MikeMc68> juxta has launched? Cool
[09:23] rjharrison (~rharrison@gateway.hgf.com) joined #highaltitude.
[09:23] <adhoc> ok, i haven't seen anything since horus and the chase cars stopped tracking near town of Murray Bridge
[09:23] <rjharrison> Cool
[09:23] <jcoxon> morning rjharrison
[09:23] <rjharrison> adhoc I assume you're in oz
[09:23] <rjharrison> Hi jcoxon
[09:23] <rjharrison> Success I see
[09:23] <jcoxon> thanks for the voicemail
[09:23] m0tek (~81a90a38@gateway/web/freenode/x-evkbcyhqplbkeldn) joined #highaltitude.
[09:23] <jcoxon> apologies for not picking up
[09:23] <m0tek> hi all
[09:23] <rjharrison> I had a very long chat with terry yesterday
[09:23] <m0tek> what's t'latest?
[09:23] <rjharrison> jcoxon np
[09:23] <adhoc> rjharrison: yes, horus was launched near my house
[09:24] <rjharrison> adhoc cool
[09:24] <rjharrison> So we're waiting for an update and if the pics have come out
[09:24] <m0tek> I think UKHAS is now really just HAS
[09:24] <rjharrison> lol
[09:24] <m0tek> or GHAS (global)
[09:24] <rjharrison> Tis true UKHAS is a bit regional these days
[09:25] <jcoxon> thats very true
[09:25] <jcoxon> not sure what the solution is
[09:25] <m0tek> commonwealth HAS
[09:25] <jcoxon> don't really know how we'd extract teh UK bit to make it GHAS :-D
[09:26] <rjharrison> Yep
[09:26] <jcoxon> thats very true
[09:26] <rjharrison> Perhaps a new domain with a redirect from ukhas
[09:26] <MikeMc68> juxta's tracker is confusing
[09:26] <MikeMc68> everything is the same colour
[09:26] <adhoc> MikeMc68: the trails themselve are/were different colours
[09:26] <jcoxon> MikeMc68, i agree, i'm thinking perhaps we should not have 'track's for chase cars, just a single placemarker
[09:27] <rjharrison> jcoxon that would be good
[09:27] <jcoxon> it doesn't help that the flight path goes back on itself, usually its more obvious
[09:27] <rjharrison> Plus there way natrium has encoded he the balloons they are limited
[09:27] <jcoxon> i think rjharrison and natrium need to combine their code to make a super tracker :-p
[09:27] <rjharrison> A gradient would be good to indicate hight :)
[09:28] <m0tek> or checkboxes on the right to be able to perhaps just see current, all, or nothing
[09:28] <rjharrison> Yep
[09:29] <rjharrison> Talkig of which I have updated last pos
[09:29] <MikeMc68> that's a good idea
[09:29] <rjharrison> lastpos.php
[09:30] <m0tek> cool
[09:30] <rjharrison> http://ukhas.org.uk/projects:dlistener
[09:30] <m0tek> rjharrison: thanks for mentioning that. will update the trackatron software now before I forget
[09:30] <rjharrison> At the bottom
[09:31] <MikeMc68> so I take it juxta balloon is now on the ground?
[09:31] <rjharrison> I have remove the last comma too
[09:31] <rjharrison> MikeMc68, yep and has been for a few hours
[09:31] <MikeMc68> what altitude did it get to?
[09:31] <rjharrison> 100,000 ft
[09:31] <adhoc> 27000
[09:31] <adhoc> 27000 meters
[09:32] <MikeMc68> cool
[09:32] <jcoxon> rjharrison, is it possible to add the custom field to lastpos
[09:32] <adhoc> hit -17c at 21,000 m
[09:32] <jcoxon> as i was planning to make some graphs etc
[09:33] <rjharrison> Yep
[09:33] <rjharrison> Sure
[09:33] <jcoxon> as i've now got an extra week
[09:33] <rjharrison> Infact do you want to be able to specify how many lines come back?
[09:33] <jcoxon> juxta kept his payload toasty - i'm going to rethink my payload insulation
[09:33] <rjharrison> How warm?
[09:33] <rjharrison> Heater?
[09:33] <jcoxon> don't think so
[09:34] <jcoxon> i don't think it went below 15
[09:34] <rjharrison> He had 2 cams in there with always help
[09:34] <rjharrison> which
[09:34] <jcoxon> yeah that is true
[09:34] <jcoxon> and a lot of foam
[09:35] <rjharrison> Yep, Basically you're going to have to heat if you want to match that as the cameras are in effect heaters in the payload
[09:36] <MikeMc68> was -17 the external or internal temp?
[09:36] <rjharrison> I think 25mm is fine
[09:36] <jcoxon> i'm not going to add cameras but I will add some foam over my electronics bay
[09:36] <jcoxon> just to contain it a bit more
[09:37] <russss> sodium acetate handwarmers
[09:37] <russss> you know you want to
[09:37] <jcoxon> i've actually got some
[09:37] <jcoxon> :-)
[09:38] <rjharrison> VK5ZSN : ORUS,588,15:54:59,-35.0858,139.0900,29526,78,5;21;1;117;3*69
[09:38] <rjharrison> Checksum invalid
[09:38] <jcoxon> oh the french balloon guys are planning a launch in may in northern france
[09:38] <rjharrison> so 29526 is the max alt
[09:38] <rjharrison> in meters
[09:38] <jcoxon> and they get to use 2m so we might be able to listen in
[09:38] <rjharrison> Cool
[09:38] <jcoxon> rjharrison, if you add the H does the checksum then work?
[09:38] <rjharrison> 29 526 metres = 96 870.0787 feet
[09:38] <rjharrison> Yeo
[09:39] <rjharrison> Yep
[09:39] <m0tek> jcoxon: have you given them the bug?
[09:39] <rjharrison> Well I think so
[09:39] <jcoxon> m0tek, oh this will be their 4th flight
[09:39] <m0tek> oh ok
[09:39] <jcoxon> seems they do 1 a year - i google translated their website
[09:39] <rjharrison> I really think we should consider moving away from the UK part of HAS
[09:40] <MikeMc68> yeah - just HAS

[09:41] <jcoxon> well there is ARHAB already - what makes us different is that we don't use amateur radio - in someways UKHAS is non-ARHAB
[09:41] <rjharrison> Can you put some thought into that james I'm happy to orgainse the technicals
[09:41] <jcoxon> of course - though i'm not the boss!
[09:41] <rjharrison> Yep but UKHSA is a friendly face to HAB
[09:41] <jcoxon> :-p
[09:42] <m0tek> TFFOHAB
[09:42] <jcoxon> yes very much so - perhaps we can use #highaltitude as thats a neutral centre point
[09:42] <rjharrison> jcoxon well you sort of are. Grandfathered in so to speak :P
[09:42] <jcoxon> hehe
[09:42] <rjharrison> HighAltitude.org would work
[09:44] <rjharrison> hum bloody name baggers
[09:44] <MikeMc68> has anyone measured air pressure on a flight?
[09:44] <m0tek> yep
[09:45] <rjharrison> juxta just did
[09:45] <MikeMc68> ok i'll have to check what instrument he used

[09:47] <m0tek> puns n that
[09:47] <rjharrison> lol
[09:47] <rjharrison> That's quite good ed
[09:48] <rjharrison> jcoxon sorry to hear about the posponement
[09:48] <rjharrison> like you say will give you a bit longer to get the graphing sorted
[09:48] <rjharrison> m0tek, I;m going to add the custom filed for james
[09:49] <rjharrison> Actually that is not quite so easy
[09:49] <jcoxon> rjharrison, yeah, well i'm not sure how legal it is to cross multiple international borders
[09:49] <rjharrison> Perhaps I'll leave the lastpos as is
[09:49] <jcoxon> even though it would be a lot more fun
[09:49] <rjharrison> jcoxon, I had thought that already
[09:50] <rjharrison> I thought you had the bug after the last launch
[09:51] <jcoxon> launch this weekend if we did a BH2 we could make over a 1000km
[09:52] <jcoxon> rjharrison, to tell the truth - i just want the tanks to work (might slightly sick of them as i've been working on/off on them for 9months or so)
[09:52] <jcoxon> and ideally over the UK in a nice figure of 8 like juxtas flight :-p
[09:53] <rjharrison> Yep
[09:53] <rjharrison> The fig 8's are cool

[10:03] <Laurenceb> great stuff, recovered?
[10:03] <adhoc> i think so
[10:04] <adhoc> well haven't heard yet, but the tracking probably shows that
[10:17] <rjharrison> adhoc, Have you a mobile number for juxta
[10:18] <rjharrison> Time to get an update the anticipation is killing me :)
[10:18] <rjharrison> Well it'S an excuse not to be getting on with my work :)

[10:44] <rjharrison> Hey
[10:44] <rjharrison> Hows did it go
[10:44] <rjharrison> I think a conf call is needed for later
[10:44] <juxta_> no problems a good success :)
[10:45] <MikeMc68> hi juxta
[10:45] <juxta_> sure, I'm not home just yet, but agreed
[10:45] <juxta_> hey MikeMc68
[10:45] <rjharrison> Here is a graph of the ascent http://www.robertharrison.org/listen/time.png
[10:45] <juxta_> oh wow, thanks rjharrison :D
[10:45] <rjharrison> Did you get some nice pics
[10:46] <juxta_> sadly not really
[10:46] <juxta_> I had lens filters in front of the cameras
[10:46] <juxta_> embedded in the payload
[10:46] <juxta_> and the got iced up :(
[10:46] <juxta_> they*
[10:46] <MikeMc68> oh no !
[10:46] <juxta_> I know :(
[10:47] <russss> hah
[10:47] <juxta_> also it got tangled on the way down
[10:47] <russss> so your nice warm toasty payload came back to bite you
[10:47] <juxta_> so I think impact was probably 60ish km/h
[10:47] <juxta_> yeah it was warm inside I think
[10:47] <juxta_> is there a temp graph rjharrison?
[10:47] <MikeMc68> i wonder why yours iced up and others didn't
[10:48] <juxta_> max alt was 29606 from the NMEA data onboard
[10:49] <rjharrison> Not yet I need to know what the custom fields are
[10:49] <rjharrison> 2;35;28;1014;43
[10:49] <rjharrison> The temp should have been in the xml file my mistake
[10:50] <rjharrison> juxta_ normally the ice goes after a while have you looked at the later pics?
[10:51] <MikeMc68> 97,132 feet
[10:51] <juxta_> rjharrison: nah, its there the whole way :(
[10:51] <rjharrison> Well there is always tomorrow :)
[10:52] <MikeMc68> how strange
[10:52] <juxta_> I think next time no sealed up lens filter
[10:52] <juxta_> rjharrison: custom fields are:
[10:52] <rjharrison> Yep
[10:52] <juxta_> numsats, intemp, ext temp, hpa (pressure), humidity %
[10:52] <rjharrison> The early pics should have been ok?
[10:52] <juxta_> maybe temp is the other way around
[10:52] <juxta_> yeah the early pics are OK
[10:52] <juxta_> but we the a bit too much gas in it, it really rocketted up
[10:54] <MikeMc68> probably why it popped slightly early
[10:54] <juxta_> yeah
[10:55] <MikeMc68> but you got your payload back that's the main thing
[10:55] <juxta_> :D
[10:55] <Darkside> haha
[10:55] <MikeMc68> which means it's survived to fight another day
[10:55] <juxta_> the spot backup tracker worked
[10:55] <Darkside> congrats on the flight juxta_
[10:55] <juxta_> but it wasnt all that useful
[10:55] <juxta_> thanks Darkside
[10:55] <juxta_> :)
[10:55] <Darkside> ahh, i was told you might have this info: BOM balloons
[10:55] <Darkside> times/frequencies
[10:56] <Darkside> always been interested, never had the right info
[10:57] <Darkside> i've heard it's 9AM/9PM, and i know it's between 400-404MHz
[10:57] <Darkside> never been sure tho
[10:58] <juxta_> Darkside: I believe most met offices go for 00:00 UTC/12:00 UTC
[10:58] <juxta_> thats what ours does at least
[10:58] <juxta_> met band is 401-403mhz, most offices use vaisala radiosondes, either WBFM or FM
[10:58] <juxta_> about 2400baud
[10:58] <Darkside> cool
[10:58] <Darkside> hmm so 10:30AM/PM atm
[10:59] <Darkside> might be able to catch tonights one then :)
[10:59] <Drift> 11:00AM UTC currently
[11:00] <Darkside> yeah
[11:00] <Darkside> +10.5
[11:00] Action: Drift tunes in radio
[11:00] <Darkside> also i mean the launches are at 10:30AM/PM CDT
[11:00] <MikeMc68> i never thought about that - could we listen in on Met Office balloons from the UK ?
[11:02] <juxta_> yeah MikeMc68 you can
[11:02] <juxta_> if they use vaisala sondes, checkout sondemonitor
[11:02] <juxta_> :)
[11:02] <Darkside> sondemonitor is the proram i need, right?
[11:02] <juxta_> Darkside: yep
[11:03] <Darkside> coool
[11:03] <Drift> http://www.coaa.co.uk/sondemonitor.htm
[11:03] <Darkside> they're using analog sondes atm aren't then?
[11:03] <Darkside> they*
[11:03] <juxta_> Darkside: are you in Adelaide?
[11:03] <Darkside> yep
[11:03] <Darkside> :)
[11:03] <juxta_> ahh, hehe
[11:03] <Darkside> eastern suburbs :)
[11:03] <juxta_> yeah they are launching analog at the moment
[11:04] <Darkside> awwww
[11:04] <Darkside> and i don't have any dopper equipment
[11:05] <MikeMc68> interesting
[11:06] <juxta_> you can track the analog's with a beam
[11:06] <juxta_> thats what we did last time Darkside
[11:06] <Drift> where abouts are they launched from?
[11:06] <MikeMc68> See that place - coaa - i've been there
[11:07] <MikeMc68> It's in Portugal - spent a week on holiday there
[11:07] <Darkside> juxta_: i don't have a directional enough beam :P
[11:07] <Darkside> only 5 elements, and tuned fo 477MHz :P
[11:07] <Drift> i do :P
[11:07] <Drift> i have 6el for 437mhz
[11:08] <juxta_> MikeMc68: the author of sondemonitor lives in portugal and also here
[11:08] <juxta_> he alternates between the 2
[11:08] <juxta_> he was listening in the launch today :)
[11:08] <Darkside> Drift: that's only gonna be about a 45 degree angle
[11:09] <Drift> eh?
[11:10] <Darkside> i mean, the directionality of it
[11:10] <Darkside> you won't be able to pin down the location accurately
[11:10] <MikeMc68> If it is the guy that runs COAA I know him
[11:10] <Darkside> well, precisely
[11:11] <Drift> doesnt bother meee
[11:11] <Darkside> heh
[11:11] <Drift> i just wanna hear it
[11:11] <Darkside> it will get you a rough fix, and yeah, that will work
[11:12] <Darkside> i'm gonna try my UHF antenna tonight
[11:13] <Darkside> juxta_: they're launched from the airport, right?
[11:13] <juxta_> ok, impact speed was 62km/h
[11:13] <juxta_> yeah they are Darkside
[11:13] <juxta_> but you can hear them anywhere really
[11:13] <Darkside> ok cool
[11:13] <juxta_> just make a wuater wave for 401
[11:13] <juxta_> quater
[11:13] <Darkside> i'm just gonna use my UHF CB antenna tonight
[11:13] <juxta_> so long as your radio supports WFM you'll be OK
[11:13] <Darkside> hmmm, that may be a problem...
[11:13] <juxta_> yeah that'll probably even work
[11:14] <Darkside> i only have a crap scanner at the moment... one of the low end uniden models
[11:14] <Darkside> used to have a UBC396T, but that wen to my dad
[11:14] <Darkside> now i only have a UBCD92XLT
[11:14] <Drift> handheld jigger?
[11:14] <MikeMc68> juxta was it damaged?
[11:15] <Darkside> aaaand i don't think that does wide FM...
[11:15] <Darkside> Drift: yerp
[11:15] <Drift> yer ive got one of them somewhere
[11:15] <Darkside> heh
[11:15] <Darkside> i'm pretty sure it doesn't do WFM on any band
[11:15] <Darkside> i guess NFM won't be enough bandwidth to get the signal, will it
[11:15] <Darkside> well, all of it
[11:16] <juxta_> Darkside: you'll hear noise
[11:16] <juxta_> but nothing that you could decode :(
[11:16] <juxta_> the digi ones dont use WFM
[11:16] <Darkside> ahh
[11:16] <juxta_> MikeMc68: no damage to any of the gear
[11:16] <Darkside> what kind of mode is the analog sondes?
[11:16] <juxta_> the foam took the impact well
[11:16] <juxta_> Darkside: i forgot, sgp92 or somthing
[11:16] <juxta_> forget*
[11:16] <Darkside> so... a digital mode? :P
[11:17] <juxta_> oh
[11:17] <juxta_> sorry
[11:17] <juxta_> misread the question
[11:17] <juxta_> so erm
[11:17] <Darkside> just looking for into on what exactly the analog modes transmit
[11:17] <juxta_> yeah I'm not 100%. I think 2400baud FSK on FM
[11:17] <juxta_> WFM*
[11:18] <Darkside> interesting
[11:18] <Darkside> ahh 2400 baud..
[11:18] <Darkside> hrmmmmmmm
[11:18] <Darkside> need to get a better radio :)
[11:19] <juxta_> the analog ones dont give you much info
[11:19] <juxta_> you can see a temp/pressure curve
[11:19] <Darkside> hrmm
[11:19] <juxta_> but unless you have calibration data it doesnt have real meaning
[11:19] <juxta_> asides from seeing the burst point etc
[11:19] <Darkside> i might take a look at the spectrogram at least, see what i can see
[11:20] <Darkside> 40 minutes..
[11:20] <juxta_> they go up about half an hour earlyu
[11:20] <Darkside> wha
[11:20] <juxta_> to reach apogee at the right time
[11:20] <Darkside> so 10pm?
[11:20] <juxta_> yeah
[11:20] <juxta_> around then
[11:20] <MikeMc68> juxta what did you use to measure pressure?
[11:20] <juxta_> it varies
[11:21] <Darkside> interesting, i guess that means no airplanes flying in or out about then
[11:21] <juxta_> hah, maybe Darkside
[11:21] <Darkside> :s
[11:21] <Darkside> seriously
[11:21] <juxta_> CASA seem pretty erm
[11:21] <Darkside> what if it drifts into the flight path?
[11:21] <juxta_> well, they seem a little confused as to what it is they should do
[11:21] <juxta_> i mean the met guys do it right im sure
[11:22] <juxta_> but casa are a bit off
[11:22] <juxta_> odd*
[11:22] <Darkside> hahaha, ok
[11:22] <juxta_> MikeMc68: an absolute pressure transducer
[11:22] <MikeMc68> where did you get it?
[11:22] <juxta_> I'll go for a beter one next time, this one didnt have enough range
[11:22] <juxta_> it topped out at about 14,000m
[11:22] <juxta_> I bought it on farnell
[11:23] <Drift> Darkside, 401.630mhz
[11:23] <Darkside> Drift: you pickign it up?
[11:23] <Drift> yer
[11:23] <Darkside> now?
[11:23] <Darkside> shit ok
[11:23] <Darkside> getting ot my radio..
[11:23] <Drift> 401.620
[11:24] Action: Drift grooves to the beat
[11:24] <juxta_> haha
[11:24] <Drift> its like something from NES
[11:24] <juxta_> the whiney high pitched squeal
[11:24] <Drift> like in the underground castle thing in super mario when you press pause
[11:24] <Darkside> hahahaha
[11:24] <Darkside> oh yes
[11:24] <Darkside> i hear it
[11:24] <Darkside> even through i'm at 401.61825
[11:24] <Darkside> how the hell do i change the step
[11:24] <Darkside> stupid radio
[11:25] <Drift> lol mash alot of buttons, i hate that radio so much
[11:25] <Darkside> but still
[11:25] Action: Darkside is grooving
[11:25] Action: Drift grooves
[11:25] <Darkside> this woudl make a good techno beat
[11:25] <Darkside> or something
[11:25] <Drift> lol
[11:27] <juxta_> listen to it in SSB
[11:27] <juxta_> it sounds horrible
[11:27] <Drift> i would if i had ssb lol
[11:27] <Darkside> i can't bloody set the step on this thing
[11:28] <Darkside> so i can[t get to 401.620
[11:28] <Darkside> dammittttttt
[11:28] <Drift> ur close enough
[11:28] <Darkside> nah
[11:28] <Darkside> i wonder...
[11:28] <Darkside> can i program my motorola fast enough
[11:28] <Drift> i can hear it 401.615 - 401.635
[11:28] <Darkside> my motorola GM950+ should get down to there
[11:29] <Darkside> hurry uppp..... load you stupid VM..
[11:29] <MikeMc68> member:juxta_ where did you get your pressure sensor please?
[11:30] <juxta_> hey MikeMc68, I got it from Farnell
[11:30] <juxta_> farnell.com.au/.co.uk
[11:30] <MikeMc68> cool
[11:31] <Darkside> ahh crap my moto will only go down to 403
[11:31] <Darkside> shiiiiiiiiiii
[11:31] <juxta_> but the one natrium42 used is better though
[11:31] <Darkside> ok, going out the back with my bean
[11:31] <Darkside> beam*
[11:32] <Drift> its NW somewhere i think
[11:33] <Darkside> stupid radio with no signal strength meter...
[11:33] <Darkside> i'm picking the trtansmission up every way i point the antnena, even with squelch set to max
[11:33] <Darkside> eoah
[11:33] <Darkside> it just stopped
[11:34] <Darkside> no wait, nvm
[11:34] <Darkside> well, this has been fun :) i need to get a better radio :)
[11:36] Action: juxta_ is going home, back soon, will you be in rjharrison?
[11:41] <rjharrison> Yep juxta_
[11:42] <rjharrison> juxta_ just sorting out the graphs
[11:42] <Darkside> rjharrison: thanks for the rtty code :)
[11:42] <rjharrison> Darkside your welcome

[11:43] <Darkside> this isn't for the balloon :)
[11:43] <Darkside> this is for another project im working on
[11:45] <rjharrison> Darkside cool it's there for the taking what are you making / doing?
[11:45] <Darkside> a HF telemetry system
[11:46] <rjharrison> Cool, project page?
[11:46] <Darkside> i was just experimenting with some data modes on a HF signal generator i've got
[11:46] <Drift> pix or ban :)
[11:46] <Darkside> AD9835 - SPI controlled direct digital synthesis signal gen
[11:46] <Darkside> hah, no pix
[11:46] <Darkside> it's just in prototyping atm
[11:46] <rjharrison> cool
[11:47] <Darkside> could be used on a balloon tho :)
[11:47] <Darkside> HF telemetry would go a heck of a long way..
[11:47] <Drift> what course are you doing at uni again?
[11:47] <Darkside> the final aim of the project is a telemetry system running at 5MHz, for use on data collection points in the antarctic
[11:48] <Darkside> Drift: Elec eng
[11:48] <Drift> ah cool
[11:48] <Drift> i have a few friends doing aerospace and one doing mechatronic
[11:48] <Darkside> nice
[11:49] <Drift> well, one just finished and is working for BAE now
[11:49] <Darkside> wait............
[11:49] <Darkside> i know that person.....
[11:49] <Darkside> name?
[11:49] <Drift> alex
[11:50] <Darkside> hmm not sure
[11:50] <Drift> ziegeler
[11:50] <Darkside> nah, don't know them

[11:50] <Darkside> hmm
[11:50] <Darkside> i dunno then..
[11:52] <rjharrison> http://www.robertharrison.org/listen/time.png
[11:52] <rjharrison> this is juxta's graph inc temp and alt
[11:53] <Darkside> 40 degree internal temp?
[11:53] <Darkside> is that normal?
[11:53] <rjharrison> Yep good insulation
[11:53] <Darkside> heh ok
[11:53] <rjharrison> 2 cams and loads of foam bit high for my liking
[11:54] <Darkside> insulation is something i'm gonna have to look at too..
[11:54] <Drift> how high are u gonna go Darkside
[11:54] <Darkside> Drift: its more if my system gets placed in the antarctic
[11:54] <Darkside> it gets damn cold down there
[11:54] <Drift> o yer
[11:54] <Darkside> record minimum -80 degrees C..
[11:54] <Drift> you can digg it
[11:55] <Darkside> i don't know of *any* microcontroller that will work at that temp
[11:55] <Drift> chuck a heater in there
[11:55] <Darkside> power concerns
[11:55] <Drift> solar
[11:55] <Darkside> i'm still not sure what kind of power source i'm gonna get
[11:55] <Darkside> Drift: dark for half the year
[11:55] <Drift> tidal
[11:55] <Darkside> lol @ tidal
[11:55] <Drift> :)
[11:56] <Darkside> i'm still not sure where this is going to be used, still waiting for that info
[11:56] <Drift> still pretty cool imo
[11:56] <Darkside> i aim to do some testing with dry ice tho
[11:56] <Darkside> and i know i'm gonna have to use an oven controlled crystal oscillator to stop frequency drift
[11:58] <Darkside> even then it might not work...
[11:58] <Darkside> i guess i'll have to do lots of testing..
[11:58] <Drift> create a blog or something about it so i can keep track of what ur doin
[11:58] <Darkside> heh
[11:58] <Darkside> maybe
[11:59] <Darkside> i don't normally do blog type stuff, but i might give it a go
[11:59] <Drift> bbs
[12:00] <Darkside> i kind of started something at http://darklomax.org/blog/

[12:29] <rjharrison> Hey juxta
[12:29] <rjharrison> Welcome back
[12:30] <juxta> hey rjharrison
[12:30] <juxta> cheers
[12:30] <rjharrison> http://www.robertharrison.org/listen/time.png
[12:30] <rjharrison> Here is the graph with the temps on it too
[12:30] <juxta> brilliant, thanks!
[12:30] <juxta> looks like you filtered out those 85 deg outlyers
[12:30] <russss> that's quite a warm external temperature
[12:31] <rjharrison> Yep :)
[12:31] <rjharrison> What where those
[12:31] <juxta> which were a result of my lazy code & the sensors
[12:31] <russss> I suppose it's quite warm in australia
[12:31] <SpeedEvil> singlebit errors?
[12:31] <rjharrison> Looked like bad data
[12:31] <rjharrison> Yep
[12:31] <russss> :P
[12:31] <juxta> 85 deg c is the 'default' value for those onewire sensors
[12:31] <rjharrison> I know it's warm out there but not that warm :)
[12:31] <juxta> when they havent actually worked out what the temp is after you request it
[12:32] <rjharrison> Oh you can sense for that
[12:32] <juxta> yeah
[12:32] <juxta> i know
[12:32] <juxta> but I forgot
[12:32] <rjharrison> np
[12:32] <SpeedEvil> You got it back then?
[12:32] <rjharrison> They seemed to be pretty good all said and done
[12:32] <juxta> also I think the ext temp was colder than that, but the sensor was mostly embedded in the foam
[12:32] <juxta> yeah we got it back no troubles at all
[12:32] <juxta> we had 3 chase cars
[12:32] <rjharrison> Yep I'v had that before too
[12:32] <SpeedEvil> Great for a first attempt!
[12:33] <juxta> my internet connection was dicky, vk5zsn had a great connection
[12:33] <juxta> and the other chase car had no internet
[12:33] <rjharrison> You have to upload a few pics and let us have a look
[12:33] <rjharrison> flickr?
[12:33] <rjharrison> you'll
[12:33] <juxta> but we realised it was coming down fast and it was near us, so I got on the radio with the third car and had them get on the top of a small hill with the yagi
[12:33] <juxta> they managed to get it all the way down to touchdown
[12:33] <juxta> and I was about 1km away when it landed, I could still hear it
[12:33] <SpeedEvil> :)
[12:34] <rjharrison> And keep the singal after touchdown?
[12:34] <rjharrison> Cool
[12:34] <juxta> yeah :)
[12:34] <juxta> the payload took the impact quite well
[12:34] <juxta> given how hard it hit
[12:34] <rjharrison> That is nice when it's like that
[12:34] <rjharrison> How deep was the crator?
[12:34] <juxta> haha
[12:34] <rjharrison> :)
[12:34] <juxta> no crater, but the cows were interested
[12:35] <rjharrison> Yep they can be buggers and stamp on the payload
[12:35] <rjharrison> It's always good to have a stick
[12:35] <rjharrison> Did you meet the local farmer
[12:35] <rjharrison> We should skype for 10 mins
[12:35] <juxta> yeah, we asked for permission to go in
[12:35] <rjharrison> Quicker than typing everything
[12:35] <Drift> we wondered if u were askin permission :P
[12:36] <rjharrison> You can see it on the track

[18:37] <DanielRichman> Ohright; you mean stuff you can put on a balloon?
[18:37] <SpeedEvil> Atmospheric measuremenants, cosmic ray measurememnts, solar measurements, telescopes pointing through the clear skyu
[18:37] <SpeedEvil> photometrology of the ground
[18:38] <SpeedEvil> RF studies
[18:39] <Lunar_Lander> yeah
[18:40] <Lunar_Lander> that is what goes into the "Physics" section
[18:41] <Lunar_Lander> Chemistry would be air samples, CO2 analysis, Ozone concentration, trace gases
[18:41] <SpeedEvil> particulates
[18:41] <Lunar_Lander> yes
[18:41] <Lunar_Lander> I only give examples :)
[18:43] <Lunar_Lander> and well, biology category is quite empty for me
[18:43] <DanielRichman> Die Biologie ist nicht fast leer, man kann die Maus an einem Ballon setzten, um zu sehen, was passiert.
[18:44] <Lunar_Lander> hm, but then animal protectors will scream and shout
[18:44] <Lunar_Lander> (good german btw!!! :))
[18:45] <DanielRichman> Lunar_Lander, not exactly constructed in real-time
[18:45] <Lunar_Lander> yeah
[18:47] <Lunar_Lander> only thing I ever heard of was that they took an apparatus which collected bacteria and so on
[18:48] <DanielRichman> Hmm, that sounds like fun. Would be better to somehow preserve the bacteria in its native temperature and air pressure so you can really see what's going on up there before it dies?
[18:49] <Lunar_Lander> yes
[18:49] <Lunar_Lander> that was done also
[18:49] <Lunar_Lander> but the other apparatus sucked in air and took bacteria samples
[18:49] <Lunar_Lander> and when the balloon got back home, they looked what they had captured
[18:52] <Lunar_Lander> you know what I mean?
[18:54] <DanielRichman> yeah
[18:54] <DanielRichman> Lunar_Lander, do you know if they found anything interesting?
[18:55] <Lunar_Lander> well this was done twice
[18:55] <MikeMc68> For my launch I am going to send up a small glass vial with Tardigrades in to see how they survive the UV, etc.
[18:55] <Lunar_Lander> on a manned balloon in 1935, the "Explorer II"
[18:55] <MikeMc68> http://en.wikipedia.org/wiki/Tardigrade
[18:55] <Lunar_Lander> they found five bacteria and five molds between 11 and 22 km
[18:55] <Lunar_Lander> and then on BEXUS 7 in 2008
[18:56] <Lunar_Lander> but they did not completely checked their samples
[18:56] <DanielRichman> ok zeusbot .
[18:56] <Lunar_Lander> they want to do PCR-DNA checks you know?
[18:56] <Lunar_Lander> cool Mike
[18:56] <Lunar_Lander> I only recently heard of them
[18:57] <MikeMc68> they can withstand temperatrues down to close to absolute zero
[18:57] <Lunar_Lander> yeah
[18:57] <MikeMc68> and as high as 151 degrees
[18:57] <Lunar_Lander> Indestructible :P
[18:58] <Lunar_Lander> yeah
[18:58] <Lunar_Lander> alive at vacuum
[18:58] <Lunar_Lander> alive after 10 years without water
[18:58] <MikeMc68> yup
[18:59] <MikeMc68> not sure about high UV though
[18:59] <MikeMc68> but i doubt it will harm them
[18:59] <Lunar_Lander> they resist 5000-6000 Gy!
[18:59] <Lunar_Lander> thousand times of what is deadly for humans
[18:59] <Lunar_Lander> yeah, it will be cool to see that
[18:59] <Lunar_Lander> where can one get them?
[19:02] <Lunar_Lander> oh and MikeMc68, you need quartz glass
[19:02] <Lunar_Lander> but you probably know that already :)

[19:22] <MikeMc68> lead in the glass blocks UV?
[19:25] <Lunar_Lander> no
[19:25] <Lunar_Lander> it's just that the glass has an "optical window"
[19:25] <Lunar_Lander> these are the wavelenghths it will allow to go through
[19:25] <Lunar_Lander> and the lower bound is at about 350 nm
[19:39] <Lunar_Lander> that is why you need quartz MikeMc68

[20:41] <Laurenceb> SpeedEvil: ever dismantled your KADA 852D ?
[20:41] <Laurenceb> mine had the top dented in about 1cm in the box :-/
[20:41] <Laurenceb> wondering if its damaged anything
[20:41] <SpeedEvil> no.
[20:42] <SpeedEvil> there are assembly videos on youtube
[20:43] <Laurenceb> http://www.youtube.com/watch?v=quGs3q9nsA8
[20:43] <Laurenceb> I see
[20:44] <Laurenceb> fun job
[20:47] <Laurenceb> looks like it doesnt mind getting bashed from above - they had removed some of the polystyrene from the top to stick in the spare bits I ordered
[20:47] <Laurenceb> and the handle got banged as a result
[20:49] <Laurenceb> I like their screwdrivers

[20:59] <rjharrison> it was ment to be an 8800 but they put in a 8900 by accident
[20:59] <rjharrison> It's for permanent in car use
[20:59] <rjharrison> on the repeater etc
[21:00] <edmoore> is that what you're telling the wife?
[21:00] <rjharrison> even has a data port and wideband rx

[23:03] <rjharrison> Hows it going
[23:04] <rjharrison> I got a new radio today an ft-8900R
[23:13] junderwood_ (~John@adsl.jcu.me.uk) left irc: Quit: Leaving
[23:16] <RocketBoy> cool - good for local comms
[23:20] <RocketBoy> and 868 rx!
[23:34] <rjharrison> RocketBoy yep
[23:34] <rjharrison> But my tx sounds crap on the 8900 I think that is the way i make the signal
[23:35] <RocketBoy> ? how do u mean
[23:35] <rjharrison> I'm using pwm atm to get the oscillations to make the tx do it's stuff
[23:35] <rjharrison> So it sounds and looks pretty ropey
[23:36] <rjharrison> How do you drive your tx3h?
[23:36] <RocketBoy> PWM A2D is all about the right filtering IMO
[23:37] <RocketBoy> the 300bps modem I used to use when we 1st started HABing was a 4bit linear DAC - which seemed good enough
[23:38] <RocketBoy> but the one I used for HF is a PWM DAC
[23:38] <rjharrison> can you remind me once again how we drive the tx I thought it was with an oscilating signal
[23:39] <RocketBoy> for FM (AFSK?)
[23:39] <rjharrison> Yep thats the one
[23:39] <rjharrison> sorry I should of said that
[23:40] <RocketBoy> So you need to generate the equivalent of two frequency s - sine wave shape
[23:41] <rjharrison> Oh yep that's it
[23:41] <RocketBoy> and sap between them for the two symbols (0 and 1)
[23:41] <RocketBoy> swap
[23:41] <rjharrison> and the smoother the frequencies the better
[23:41] <rjharrison> I think at the moment I just jump from one to another
[23:42] <RocketBoy> ideally in such a way that phase is maintained at the transitions (called coherant phase)
[23:42] <rjharrison> and I think I remember that it was better to jump at a peak or ttough
[23:42] <rjharrison> trough
[23:42] <rjharrison> yep you beat me
[23:43] <rjharrison> PWM DAC is a DAC driven by PWM input ?
[23:43] <RocketBoy> depends - if the two frequencys are related to the bitrate then you can swap at zero (or at any other fixed position)
[23:43] <RocketBoy> but typically the frequencys arn't
[23:44] <SpeedEvil> what frequency is the PWM?
[23:44] <rjharrison> Good question I can't remember one sec
[23:45] <SpeedEvil> it's got to be at least a couple of orders of magnitude over the signal output for easy filtering
[23:47] <RocketBoy> yeah - the PWM frequency and the number of DAC bits you want to achieve and are related (and the LPF order)
[23:47] <RocketBoy> I wrote somthing up for the UKHAS wiki about it
[23:48] <rjharrison> Ooh did you wher is it
[23:48] <rjharrison> I need to calculate the frequency
[23:49] <rjharrison> I think I nees to sllep
[23:49] <rjharrison> sleep
[23:50] <rjharrison> RocketBoy can we chat about this another time
