[02:49] <natrium42> fergusnoble, ooh, cool
[02:49] <fergusnoble> yeah, erm i still havnt finished the grib downloading script but ill just bodge some gribs that will work for testing
[02:53] <fergusnoble> ok, there are some gribs loaded now
[02:54] <fergusnoble> if you run ./pred -igribs/ lat lng alt drag_coeff burst_alt ascent_rate
[02:54] <fergusnoble> it will putput the path in csv to stdout
[02:55] <fergusnoble> do ./pred -h to see what other options there are
[02:58] <natrium42> awesome
[02:59] <natrium42> i will take a look a bit later as i still need to finish taxes :S
[02:59] <fergusnoble> yup sure
[03:05] rhjharrison (n=rharriso@gateway.hgf.com) joined #highaltitude.
[03:05] <fergusnoble> one other possibly confusing thing is that when the balloon bursts and you are going down you need to specify the -d option
[03:06] <fergusnoble> so it knows not to carry on up to burst and then go down again

[11:52] <hallam> hi jcoxon
[11:52] <hallam> going fine as far as I'm aware
[11:52] <jcoxon> hey Henry
[11:52] <hallam> I think they're waiting for ITV to show
[11:52] <hallam> I'm in the Engineering dept, have set up a mission control thing
[11:52] <jcoxon> is the server working okay?
[11:53] <hallam> Hope so. Fergus thinks so. Can't really test from my end at the moment
[11:53] <jcoxon> haven't seen any data come through
[11:53] <jcoxon> being filmed?
[11:53] <hallam> I won't be able to hear it until it goes up
[11:53] <hallam> apparently
[11:54] <hallam> Fergus has 3G on the mobile station so you should get some data when they do the final test
[11:54] <jcoxon> well I'll be on my laptop after 1 just in case
[11:54] <hallam> great
[11:54] <jcoxon> running dl-fldigi?
[11:54] <hallam> yeah
[11:54] <hallam> as M0HMH
[11:54] <jcoxon> oh I see your callsign
[11:55] <jcoxon> have you selected badger?
[11:55] <jcoxon> and turned on ex extraction?
[11:55] <jcoxon> rx*
[11:55] <SpeedEvil> Wow - you have proper mission control station! /me passes hallam the '54321!' clip from Thunderbirds.
[11:56] <hallam> :)
[11:56] <hallam> Yes, have done those things
[11:56] <jcoxon> cool, need to make them preset in the future
[11:57] <hallam> it did crash a while ago

[12:16] <fergus_eee> hallam, seen jcoxon or rjharrison
[12:16] <fergus_eee> ?
[12:16] <hallam> saw jcoxon, he'll be back at 1
[12:16] <hallam> when should we expect something to show up on the tracker?
[12:17] <fergus_eee> erm, not started filling yet
[12:17] <fergus_eee> but the tracker is on if you want to try to tune in from where you are
[12:17] <hallam> but your radio check should do it, right?
[12:17] <fergus_eee> i doubt you'll get it though
[12:17] <fergus_eee> yeah

[12:19] <hallam> fergus_eee: the BNC-whatever adapter is in the correct jack on the radio, right? "ant 2"
[12:19] <rjharrison_work> how's it going
[12:19] <rjharrison_work> fergus_eee: are we due a launch?
[12:19] <fergus_eee> hallam, yes
[12:19] <hallam> rjharrison_work: we're just getting set up. I've got a telemetry station going in the Engineering dept, Fergus and the rest of the gang are about to fill at churchill
[12:19] <fergus_eee> rjharrison_work, very close, maybe 15 mins to launch tops
[12:20] <rjharrison_work> Ok i'll clear the tracker's down
[12:20] <fergus_eee> rjharrison_work, is the tracker setup for the badger strings?
[12:20] <rjharrison_work> Yep should be
[12:20] <fergus_eee> $$Badger,378,11:19:52,0,0,0,2;0;8;0;0;0;0*0E
[12:21] <rjharrison_work> I'll test it now
[12:21] <fergus_eee> ok awesome
[12:21] <fergus_eee> ive got dl-fldigit running here, not sure how to check if its working
[12:21] <fergus_eee> should it be sending the strings even though there is no gps lock?

[12:28] <rjharrison_work> YOU MUST CHANGE THE PAYLOAD TO ICARUS AND BACK TO BADGER ON THE CLIENT
[12:28] <rjharrison_work> IT SHOULD SAY 7 FIELDS NOT 11
[12:28] <rjharrison_work> Sorry about shouting
[12:28] <rjharrison_work> data will start to come through to the server then
[12:29] <rjharrison_work> ping hallam

[12:31] <hallam> ok
[12:31] <hallam> will do
[12:31] <rjharrison_work> Ok if you do the above data will flow
[12:32] <fergus_eee> ok its saying 7 fields
[12:33] <hallam> ok set to 7
[12:34] <fergus_eee> ok one string should have come through but its a bit wrong
[12:34] <hallam> how's the fill?
[12:34] <fergus_eee> anything come up your end?
[12:34] <fergus_eee> just starting
[12:35] <djellison> Nice way to get through the tedium of an afternoon at work :) Good luck boys.
[12:37] <hallam> thanks :)
[12:40] <fergus_eee> ok, bit of a hitch
[12:40] <fergus_eee> just making some minor alterations to the badger code
[12:40] <hallam> ..
[12:40] <rjharrison_work> hehe
[12:40] <rjharrison_work> Ok
[12:40] <fergus_eee> should be ok, just a small change
[12:40] <fergus_eee> will be quick
[12:40] <rjharrison_work> Don't fire a pyro by accident
[12:40] <hallam> what happened?
[12:40] <rjharrison_work> Logging to the map now
[12:41] <rjharrison_work> humm
[12:41] <rjharrison_work> many not
[12:41] <rjharrison_work> maybe not
[12:41] <rjharrison_work> one sec
[12:41] <hallam> rjharrison_work: what's the URL to see the map? (not spacenear.us, right?)
[12:45] <djellison> Badger just appeared on Spacenear
[12:45] <rjharrison_work> both

[12:47] <hallam> cool
[12:47] <fergus_eee> ok, code change done

[12:47] <rjharrison_work> Cool
[12:47] <rjharrison_work> Logging to maps now
[12:47] <fergus_eee> stopped it trying to write to the non existent sd card
[12:47] <hallam> good call
[12:47] <fergus_eee> think it was mucking up the gps code
[12:48] <hallam> is the balloon filled?
[12:48] <rjharrison_work> hallam: you need to set your payload up who is using the call sign M0NBL
[12:48] <rjharrison_work> M0NBL/M is working fine
[12:48] <fergus_eee> balloon being filled
[12:48] <fergus_eee> rjharrison_work, sweet

[12:50] <hallam> though fldigi just crashed again, gimme a sec
[12:50] <rjharrison_work> ok hallam you need to set the payload to icarus and then back to badger
[12:50] <rjharrison_work> If you restart you may be ok
[12:50] <rjharrison_work> check using http://www.robertharrison.org/listen/view.php
[12:50] <rjharrison_work> look at the bottom
[12:50] <hallam> already did that
[12:50] <hallam> I just restarted

[12:58] <fergus_eee> RocketBoy, yup
[12:59] <RocketBoy> ah - so from the log I have it seems that logging started at about 17km on the way down?
[12:59] <RocketBoy> or am I missing a log?

[13:09] <RocketBoy> shift baud bits parity stops?
[13:09] <rjharrison_work> Should all be set for you
[13:09] <RocketBoy> wow
[13:09] <rjharrison_work> If you have the latest client (last few days)
[13:09] <RocketBoy> yep
[13:09] <rjharrison_work> should be set to 8 bit
[13:09] <rjharrison_work> :)
[13:10] <RocketBoy> tis
[13:10] <hallam> RocketBoy: there are two beacons on board
[13:10] <hallam> one is badger, 50 baud 425Hz 7-N-1

[13:12] <rjharrison_work> hi jcoxon

[13:13] <jcoxon> hey all
[13:13] <hallam> rjharrison_work: are you getting packets from M0HMH?

[13:14] <hallam> ok thanks
[13:15] <jcoxon> rjharrison_work, did you turn the checksum back on after yesterday?
[13:15] <rjharrison_work> yep
[13:15] <jcoxon> okay cool
[13:15] <rjharrison_work> and i have remove prob checking for checksum valid sentances
[13:15] <jcoxon> great
[13:16] <jcoxon> mmmmm nice data
[13:16] <rjharrison_work> Yep very nice
[13:16] <jcoxon> rjharrison_work, henry has been having some crashes
[13:17] <hallam> only occasional
[13:17] <hallam> once an hour or so
[13:17] <jcoxon> something we need to get to the bottom of at some point
[13:17] <rjharrison_work> hehe hallam you can't change beacons atm
[13:18] <rjharrison_work> jcoxon: we need to remove the callsign replace in the client
[13:18] <jcoxon> okay
[13:18] <jcoxon> thats no problem
[13:19] <jcoxon> but
[13:19] <jcoxon> corruption of the callsign will result in multiple payload tracks being spawned
[13:21] <hallam> rjharrison_work: where does the "rate" come from in the window on the tracker website?
[13:21] <hallam> I hope it's not accurate (and I don't think it is)
[13:21] <rjharrison_work> good question ask natrium42
[13:22] <djellison> Hi JC
[13:22] <jcoxon> djellison, hey
[13:22] <rjharrison_work> wow weird track
[13:22] <rjharrison_work> and that data is correct
[13:22] <jcoxon> nah just a little spiral
[13:23] <djellison> Looks like it was trying to follow the off ramp of the M11 ;)
[13:23] <jcoxon> not much wind at that alt
[13:23] <hallam> the asc rate is pants then
[13:24] <hallam> good job I put the range trigger in for the cutdown
[13:24] <hallam> we needed 5m/s ascent
[13:25] <jcoxon> hallam, is it just you at your mission control?
[13:25] <hallam> yes atm
[13:25] <hallam> rest of team supposed to be decamping here with the school students
[13:25] <jcoxon> right
[13:26] <jcoxon> having a base station to receive data really helps with the tracking
[13:26] <jcoxon> djellison, how is UMSF these days?
[13:30] <rjharrison_work> Very nice and clean data
[13:30] <djellison> A stead 4 m/sec now - that's not too far off 5.
[13:30] <rjharrison_work> no sign of fergus_eee lgging
[13:30] <rjharrison_work> loggin
[13:30] <hallam> yeah that's better
[13:31] <hallam> rjharrison_work: they're just getting set up in the car, I think
[13:31] <hallam> I wonder why the ascent rate was so low to start with and went up so much
[13:31] <hallam> there's some fairly intense convective activity around here atm
[13:31] <hallam> thunderstorms
[13:31] <djellison> What do the predicts say for today?
[13:31] <hallam> maybe that explains it
[13:33] <hallam> rjharrison_work / jcoxon: could you delete the chase car track from natrium's tracker?

[13:34] <hallam> it's making it so that when the schools etc visit the website, they only see the stationary chase car instead of the balloon track
[13:34] <rjharrison_work> ok
[13:34] <hallam> thanks
[13:34] <hallam> wow
[13:35] <hallam> ascent rate has increased from 2.5m/s to 6
[13:35] <rjharrison_work> right hallam they might need to refresh browser
[13:36] <rjharrison_work> If you click on the payload the map gets centered around the last point
[13:36] <rjharrison_work> not many people know that
[13:37] <djellison> If there's Cu-Nim activity around, you'll get big asc rate jumps. From a gliding point of view - quite a boomy sort of day
[13:38] <hallam> apparently the release was pretty wild
[13:38] <hallam> they decided to do it during the 5 minutes when the storm was directly overhead, lol
[13:38] <djellison> Genius :)

[13:42] <rjharrison_work> djellison: Thanks
[13:42] <rjharrison_work> Just good to get feedback
[13:42] <hallam> I *think* the 8.9.. is the GPS-derived ascent rate

[13:42] <hallam> 0;0;0 is cutdown status
[13:43] <hallam> 10 is probably satellites or something
[13:43] <djellison> How big's the box for cutdown?
[13:44] <hallam> it will cut if it isn't above 18km altitude by the time it reaches 64km downrange
[13:44] <hallam> weird condition due to weird upper winds today
[13:44] <hallam> after a certain point it's better to keep going up because the winds blow inland

[13:44] <hallam> hi Laurenceb
[13:44] <Laurenceb> hi hallam
[13:44] <Laurenceb> long time no see
[13:44] <Laurenceb> hows it going?
[13:44] <hallam> alright
[13:45] <fergus_eee> andwere off
[13:45] <hallam> operating Nova 13 mission control atm
[13:45] <hallam> hey fergus_eee
[13:45] <Laurenceb> nice
[13:45] <jcoxon> Hi mib_w1khix06 mib_g7gxdxjz - welcome to #highaltitude
[13:45] <Laurenceb> tracking page?
[13:45] <jcoxon> spacenear
[13:45] <hallam> spacenear.us/tracking
[13:45] <hallam> fergus_eee: question when you get a chance - could you check what the altitude cutdown condition was?
[13:46] <fergus_eee> no, have to wail till iain gets to you with my lappy
[13:46] <Laurenceb> whats flying on NOVA13?
[13:46] <fergus_eee> could you tell us where to head?
[13:46] <fergus_eee> Laurenceb, its not nova13
[13:46] <Laurenceb> 13
[13:46] <jcoxon> fergus_eee, defintiely towards thetford
[13:46] Action: Laurenceb summons the devil
[13:46] <Laurenceb> 666
[13:46] <jcoxon> along A11
[13:46] <SpeedEvil> ?
[13:46] <hallam> fergus_eee: it's following the predicted path so far. Norwich.
[13:47] <hallam> Is there a nice way to get a prediction from the received data?
[13:47] <rjharrison_work> hallam: not yet
[13:47] <hallam> also looking forward to getting chase car on the tracker
[13:47] <hallam> ok I will do a manual one
[13:47] <Laurenceb> oh, space challenge 09 ? fairdoos
[13:48] <Laurenceb> www.penisinspace.com/
[13:48] <rjharrison_work> fergus_eee is working on integration of prediction from the data
[13:48] <rjharrison_work> fergus_eee: You are not logging any data
[13:49] <rjharrison_work> Hoo
[13:49] <rjharrison_work> Ooh
[13:49] <rjharrison_work> I lie you are now
[13:49] <jcoxon> Laurenceb, !
[13:49] <hallam> ah crap I was wrong, the ascent rate *is* way too low
[13:50] <rjharrison_work> fergus_eee: Do you have the gps connected to the eee
[13:50] <djellison> Yeah -ground speed is storming right now
[13:50] <rjharrison_work> Thinking chase_car
[13:51] <hallam> OK fergus_eee: Expect landing due to range cutdown, near Ludham (far side of Norwich)
[13:54] <djellison> VEry rough - that ground speed is about 108 km/h over the last 10 mins
[13:54] <jcoxon> wow
[13:54] <djellison> 18km covered in 10 mins.
[13:54] <djellison> If Google Earth is being honest about it.
[13:54] <djellison> So that's 30m/sec compared to a climb of 3-4

[13:55] <djellison> dieeed.
[13:55] <hallam> wb
[13:55] <hallam> yeah massive underfill I think
[13:56] <hallam> fergus_eee: is the GPS asc rate the last thing before the checksum?
[13:56] <fergus__eee> thats the doppler rate yeah
[13:57] <fergus__eee> not very well tested but should be working
[13:57] <Laurenceb> are you loggin git?
[13:57] <Laurenceb> I'd be interested to compare with position
[13:58] <hallam> Laurenceb: http://www.robertharrison.org/listen/view.php
[13:58] <Laurenceb> doh
[13:58] <Laurenceb> CRAPPI YAGI lol
[13:59] <djellison> in 13 mins, 23.7km ground covered ( 109 kph ) - and a gain of only 2500 m
[13:59] <jcoxon> djellison, we should soon escape the winds
[13:59] <jcoxon> and slow down
[13:59] <jcoxon> i think the predictor is good still
[14:00] <hallam> um.
[14:00] <djellison> Need the badger to stream-punch
[14:00] <hallam> fergus_eee: new landing site for you
[14:00] <hallam> it's, er
[14:00] <hallam> slightly in the middle of Norwich
[14:00] <fergus__eee> oh ok
[14:00] <fergus__eee> oops
[14:01] <fergus__eee> erm, am i now coming through on the tracker again?
[14:01] <hallam> things may change..
[14:01] <hallam> yeah, data a bit garbled
[14:01] <fergus__eee> should be better now
[14:03] <rjharrison_work> fergus__eee: much better
[14:03] <Laurenceb> maybe it'll get into the stratosphere soon
[14:03] <rjharrison_work> Clean data now
[14:03] <hallam> the martlet beacon is shifting down into the badger
[14:03] <Laurenceb> 46.2028 <- whats that?
[14:03] <hallam> might collide soon
[14:04] <hallam> that's distance from launch site
[14:04] <Laurenceb> ah
[14:04] <hallam> if that is >64 while altitude is <18000 it will cut down
[14:04] <fergus__eee> here comes the backup tracker to interfere
[14:04] <hallam> yeah
[14:04] <Laurenceb> hmm maybe I should move my rogallo to use the tracker format...
[14:04] <hallam> I wonder why they have such a different shift
[14:04] <hallam> is the backup tracker outside the box?
[14:05] <hallam> I have this lovely mission control set up and they've only just left churchill :( they're going to miss it
[14:05] <hallam> fergus_eee: any idea if I can get the eee (or the icom) to echo sound out the speakers while also feeding to fldigi?
[14:05] <jcoxon> Laurenceb, in theory the tracker format is adaptable
[14:05] <Laurenceb> yeah
[14:06] <Laurenceb> its just I dont need many of the fields...
[14:06] <jcoxon> hehe
[14:06] <jcoxon> we define each flight in an xml
[14:06] fergus_eee (n=fergus@212.183.134.65) left irc: Read error: 110 (Connection timed out)
[14:06] <jcoxon> so you have your own xml for the rogallo
[14:06] <Laurenceb> but its really come on now - maybe natrium could use pcharts to add some graphs of extra data
[14:07] <hallam> ok about to lose tracking data temporarily due to inter-beacon interference
[14:07] <hallam> nothing to do about it really I'm afraid
[14:08] <jcoxon> had this issue last flight
[14:08] <Laurenceb> guess it needs the "packet count" to distinguish different packets from one another?
[14:09] mib_w1khix06 (i=52985ab9@gateway/web/ajax/mibbit.com/x-ff2f7c83303d7855) left irc: "http://www.mibbit.com ajax IRC Client"
[14:09] <djellison> Ground speed has dropped to about 45kph
[14:09] <Laurenceb> probably leasving the troposphere
[14:09] <hallam> jcoxon: I retuned the backup one to keep it further apart
[14:10] <hallam> but to no avail
[14:10] <hallam> it might be outside the warm box
[14:10] <fergus__eee> whats the ascent rate btw?
[14:10] <hallam> about 3
[14:11] <djellison> About 9 k till the 65k limit I guess.
[14:12] <hallam> fergus__eee: which parachute got used? any guesses at the desc rate?
[14:12] <hallam> prediction is still norwich city centre if it's 5m/s desc
[14:13] <djellison> We need 5km up in the next 5km out.
[14:13] <Laurenceb> exciting at least
[14:13] <hallam> I'll be v. surprised if it doesn't cut
[14:13] <djellison> Yeah - the stream would have to stop very quick
[14:13] <hallam> at least, if it doesn't *try* to cut....
[14:14] <fergus__eee> btw, whats the latest forecast out?
[14:14] <fergus__eee> the 6am?
[14:14] <djellison> Looking at the KML from the side, it's BEGINNING to turn up, not much though
[14:15] <Laurenceb> probably in the stratosphere now - wind speed should decrease
[14:15] <hallam> fergus__eee: yeah
[14:16] <Laurenceb> we need a HALO chute
[14:16] <hallam> fergus__eee: any progress getting the chase car on the tracker? would look v. cool for the kids
[14:17] <Laurenceb> cuts at 64Km?
[14:17] <rjharrison_work> http://www.robertharrison.org/mobile.php
[14:17] <djellison> I've put a pin out at 65km / 16km on Google Earth. It'll have to get out of the stream like, now.
[14:17] <rjharrison_work> This has distance from launch
[14:18] <rjharrison_work> 64.708
[14:18] <rjharrison_work> comming down
[14:18] <rjharrison_work> ohh no
[14:19] <Laurenceb> hasnt cut
[14:19] <hallam> oh dear
[14:19] <rjharrison_work> 66.349
[14:19] <hallam> the 0;1;0 means it's tried to fire
[14:20] <rjharrison_work> is there a backup?
[14:20] <Laurenceb> :-S
[14:20] <hallam> no.
[14:20] <hallam> might be getting wet
[14:21] <Laurenceb> 13Km
[14:21] <djellison> Ahh - so it's attempted to fire.
[14:21] <rjharrison_work> might go a long ay
[14:21] <rjharrison_work> way
[14:21] <djellison> Can anyone swim?
[14:21] <Laurenceb> many years ago
[14:21] <rjharrison_work> I think the neatherlands
[14:22] <Laurenceb> ffs use resistor cutdowns
[14:22] <djellison> That cutdown flag switched right on time - so at least the code worked.
[14:24] <hallam> rjharrison_work: my predictions show it splashing about 5-10 km offshore
[14:24] <djellison> Well - a fast run back down the hill with tangled chute and envelope....might just make it.
[14:24] <hallam> heh, we can hope
[14:25] <Laurenceb> bow and arrow
[14:25] <Laurenceb> with a lo9ng line of string
[14:25] <rjharrison_work> what on board?
[14:25] <rjharrison_work> what's
[14:25] <hallam> schoolkids' experiments :/
[14:26] <rjharrison_work> camera?
[14:26] <hallam> one Canon and one Premier
[14:26] <rjharrison_work> Arse
[14:26] <hallam> we can replace those
[14:26] <fergus__eee> ok the chase car should be up on spacenear
[14:26] <rjharrison_work> Cool
[14:26] <hallam> awesome thanks fergus__eee
[14:27] <Laurenceb> is it using checksums or CRC ?
[14:27] <fergus__eee> its using the rjharrison_work checksum
[14:27] <fergus__eee> xoring bytes together
[14:27] <rjharrison_work> NMEA checksum
[14:27] <Laurenceb> I'm sure I saw one or two dodgy sentences get through
[14:28] <rjharrison_work> Laurenceb: http://wiki.ukhas.org.uk/projects:dlistener not the O for optional tooo
[14:28] <Laurenceb> I see
[14:28] <Laurenceb> yeah thats the standard way to do it
[14:28] <fergus__eee> hallam, can you work out how low we have to burst to fluke it
[14:29] <Laurenceb> I'd stick it in the send routine
[14:29] <Laurenceb> then attatch it to printf
[14:29] <Laurenceb> - stdout
[14:30] <djellison> About 60 kph ground speed still
[14:30] <Laurenceb> so you have some global u08 checksum that you set to zero, then printf the data, then send the checksum
[14:30] <djellison> About 46 km to the coast
[14:30] <Laurenceb> how fast is CRC16?
[14:34] <fergus__eee> for some reason the chase car gps is being dodgy
[14:35] <djellison> Of course, a nice track should help the Norwich Constabulary with their inquiries for speeding ;)
[14:37] <fergus__eee> maybe its getting wet
[14:37] <fergus__eee> will try to fix it when we slow down
[14:37] <fergus__eee> the dynamic prediction seems to indicate things are improving marginally
[14:37] <hallam> fingers crossed for a failed parachute
[14:38] <Laurenceb> lol
[14:38] <hallam> but I'm really not optimistic about this one
[14:38] <fergus__eee> yup
[14:38] <fergus__eee> heading to waxham
[14:38] <hallam> I can't find a prediction scenario where it doesn't splash
[14:38] <hallam> fergus__eee: got a car lat/long I can manually plot?
[14:39] <fergus__eee> nope, gps hardware is being screwy
[14:39] <djellison> Turning north - beginning of the end of the jet perhaps
[14:39] <fergus__eee> the uploading software is working a treat (thanks rob)
[14:40] <djellison> Still doing 45kph though
[14:41] <fergus__eee> hallam, have the others arrived?
[14:42] <rjharrison_work> fergus__eee: jcoxon and I
[14:43] <hallam> fergus__eee: yes, just
[14:44] <fergus__eee> cool
[14:45] <Laurenceb> whats burst altitude?
[14:45] <fergus__eee> estimated 29
[14:45] <fergus__eee> the spreadsheet isnt very accurate for such heavy payloads though
[14:46] <rjharrison_work> How heavy?
[14:46] <fergus__eee> 3.1kg
[14:46] <Laurenceb> wow
[14:46] <rjharrison_work> Ohh
[14:46] <rjharrison_work> very heavy
[14:46] <fergus__eee> yeah, for a 1.5kg balloon
[14:47] <SpeedEvil> That's your mistake - you hooked the eeepc to the balloon.
[14:47] <djellison> And a whole class of children
[14:47] <fergus__eee> hehe
[14:48] <fergus__eee> so, seeing as the balloon is still attached there are increased chances of a chute tangle
[14:48] <fergus__eee> which would be good
[14:49] <rjharrison_work> Yep if not a little hopefull
[14:49] <fergus__eee> yeah
[14:50] <rjharrison_work> Will keep my fingers crossed for you
[14:50] <fergus__eee> i think the rule is that the chute always does what you dont want it to do
[14:50] <rjharrison_work> Data is very clean
[14:50] <djellison> Middle of Norwich was a good call. Is pissing down looking at webcams.
[14:51] <fergus__eee> yeah it was a dramatic launch in all the wind and rain
[14:51] <fergus__eee> is steve tracking?
[14:51] <rjharrison_work> Straight through the centre of Norwich
[14:51] <fergus__eee> its getting close to his area
[14:51] <Laurenceb> 18Km :P
[14:52] <rjharrison_work> No he's out
[14:52] <djellison> I heard the sound of one hand clapping is it went through 16km. Or was that just me.
[14:53] <djellison> Well - nothing like the North Sea to teach kids about the reality of the scientific process.
[14:53] <Laurenceb> sudden direction change
[14:53] <djellison> Yeah - it's out
[14:53] <rjharrison_work> wow
[14:53] <djellison> Does Norwich have a congestion charge or something
[14:53] <rjharrison_work> It's teasing you
[14:53] <rjharrison_work> lol
[14:53] <Laurenceb> talk about wind shear
[14:55] <rjharrison_work> wow it's motoring now
[14:55] <SpeedEvil> Extrapolating the current trends - I vote for denmark.
[14:56] <Laurenceb> its the norwich forcefield
[14:56] <djellison> It's like it's drawing a new inner ring road
[14:56] <Laurenceb> or the aerial ring road
[14:59] <hallam> fergus__eee: how's it going?
[15:00] <fergus__eee> still on the a11
[15:01] <fergus__eee> going to keep going
[15:01] <SpeedEvil> Does this oone have cutdown?
[15:01] <Laurenceb> it didnt work
[15:02] <SpeedEvil> :/
[15:02] <SpeedEvil> Was it one of the nice acrylic tube pyros?
[15:02] <SpeedEvil> or something simpler?
[15:02] <fergus__eee> no, it was a non-pyro design
[15:02] <SpeedEvil> We should really have a wiki page with failed devices on
[15:03] <fergus__eee> resistor melting through a nylon tie
[15:03] <SpeedEvil> ah
[15:03] <Laurenceb> oh
[15:03] <Laurenceb> hmm
[15:03] <fergus__eee> SpeedEvil, we have had them work before
[15:03] <SpeedEvil> nylon is quite high melting point
[15:03] <Laurenceb> I dont use nylon
[15:03] <fergus__eee> but the weather here is pretty nasty
[15:03] <SpeedEvil> what's the resistor?
[15:03] <fergus__eee> could have frozen on the way up
[15:03] <Laurenceb> I tried several different materials and decided nylon was too high
[15:03] <fergus__eee> 3.9R iirc
[15:03] <SpeedEvil> fergus__eee: not rated for the pulse power?
[15:04] <Laurenceb> usuallty use insulation off solid core wire
[15:04] Action: SpeedEvil was planning on using a polythene strip, and a resistor rated to 350C.
[15:04] <Laurenceb> but for something that heavy...
[15:05] <SpeedEvil> Cutdown takes about a watt-minute - but it's pretty robust.
[15:05] <Laurenceb> ooh boubling back on itself
[15:05] <fergus__eee> SpeedEvil, no
[15:05] <fergus__eee> they never are in this design
[15:05] <fergus__eee> to be rated for the power they wouldnt get so hot
[15:05] <fergus__eee> as they would have to have better dissipation
[15:06] <hallam> fergus__eee: there are resistors meant to run hot
[15:06] Action: Laurenceb uses 10 ohm 0.125watt
[15:06] <SpeedEvil> fergus__eee: you get resistors specced to get to 350C operating temp
[15:06] <SpeedEvil> fergus__eee: at 1W
[15:06] <Laurenceb> wrap them in kapton tape
[15:06] <Laurenceb> thats what I do
[15:06] <SpeedEvil> fergus__eee: ceramic ones - though they'll only get to 300C or so at -55C ambient
[15:06] <fergus__eee> anyway, i doubt it was the resistor that failed first
[15:07] <fergus__eee> SpeedEvil, yeah true you can get higher temp ones, but its still very borderline within the ratings
[15:08] <fergus__eee> hallam, how are things going over with you?
[15:08] <Laurenceb> in my experience the coating can delaminate
[15:08] <fergus__eee> are people staying to watch?
[15:08] <Laurenceb> but kapton tape helps it stay together
[15:08] Action: Laurenceb is watching
[15:08] <hallam> FernFerret: yes we're all here
[15:08] <hallam> er, fergus__eee
[15:08] <SpeedEvil> fergus__eee: how? You get ones that are actually rated for continuous service at 350C case temp.
[15:08] <hallam> I think we'll watch until we lose telemetry
[15:09] <Laurenceb> fernferret? lol
[15:09] <hallam> what are you guys going to do
[15:09] <hallam> ?
[15:09] <fergus__eee> hallam, follow it to the coast
[15:09] <Laurenceb> swim
[15:09] <fergus__eee> say our goodbyes
[15:09] <hallam> where are you now?
[15:09] <Laurenceb> hijack a boat
[15:09] <fergus__eee> coming up to the norwich ring road i think
[15:09] <djellison> Preferably a Norway ferry
[15:10] <SpeedEvil> http://uk.farnell.com/vishay-dale/cw0014r000je70/wirewound-resistor/dp/1155042 for example.
[15:10] <SpeedEvil> :/
[15:10] <djellison> At last... I think it's in nearly still air
[15:10] <fergus__eee> SpeedEvil, now is not the time for me to be chacking farnell :)
[15:11] <fergus__eee> will talk it over when we're back
[15:11] <SpeedEvil> sorry. not thinking clearly ATM.
[15:11] <Laurenceb> are you driving ?!
[15:11] <fergus__eee> yeah
[15:11] <SpeedEvil> Been doing unusual amounts of manual labour.
[15:11] <hallam> fergus__eee: I think Cromer would be the best bet for a coastal site
[15:12] <djellison> The new iPhone 3GS allows you to drive and browse electronics components at the same time.
[15:12] <fergus__eee> ok, was heading to waxham but i think its moved now
[15:12] <fergus__eee> im not actually driving,
[15:12] <fergus__eee> rob is
[15:12] jcoxon (n=jcoxon@217.39.5.38) left irc: Read error: 60 (Operation timed out)
[15:12] <SpeedEvil> Hmm - hadn't been looking at the prediction - it probably is getting wet :(
[15:13] <hallam> fergus__eee: Walcott is closer, but Cromer is a bit more substantial of a town
[15:13] <fergus__eee> in terms of commandeering a boat?
[15:14] <hallam> yeah, but also getting some food in you
[15:14] <djellison> I'd go to Aylsham and wait - then see which direction it's heading on the way down
[15:14] <hallam> route to Cromer is on better roads too
[15:15] <djellison> You can go to Cromer, or then via Walsham to other coast places
[15:16] jcoxon (n=jcoxon@217.39.5.38) joined #highaltitude.
[15:16] <djellison> It's put its foot down again
[15:17] <djellison> 25k burst predict?
[15:17] <rjharrison_work> 33k
[15:18] <hallam> 32.5
[15:18] <rjharrison_work> humm heavy actually 29
[15:18] <rjharrison_work> it's a guess
[15:18] <djellison> The middle of a very wide bell curve
[15:18] <SpeedEvil> That's what - an hourish till brst?
[15:19] <SpeedEvil> well - half an hour to 90 mins probably
[15:20] <hallam> I'd say 30~50 mins
[15:22] <djellison> If I didn't know better, with these loops it's doing, I'd have thought it was a competition gliding gps trace
[15:22] <hallam> yeah it's clearly spiralling for altitude
[15:23] <djellison> I've been scrolling along the coast...apart from Cromer there is bugger all in terms of ports / boats / marinas etc. Just millions of caravans
[15:23] <hallam> fergus__eee: latest predictions are bringing it closer to shore. I still don't think the chances are good, but I wouldn't completely lose hope

[18:37] <Laurenceb> can anyone help me fix windoze ?
[18:38] <DanielRichman> You can't fix windoze
[18:38] <hallam> maybe what's up?
[18:38] <DanielRichman> you can cover up the broken bits and hope for the best
[18:38] <DanielRichman> what's wrong?
[18:38] <Laurenceb> it reboots as soon as it gets to the splash screen
[18:38] <Laurenceb> I think its due to a buggy update in mcafree antivirus
[18:38] <Laurenceb> that leads to some system files getting deleted
[18:38] <DanielRichman> any ideas which ones?
[18:39] <hallam> try system restore first
[18:39] <DanielRichman> if you have the install disk you could do a repair but then you're going to enjoy (noot!) doing all the service packs again
[18:39] <Laurenceb> I dont have the admin password
[18:39] <DanielRichman> ok
[18:39] <DanielRichman> grab a linux boot disk
[18:40] <Laurenceb> I have ubuntu installed on a partition
[18:40] <DanielRichman> Are you comfortable with cracking the password?
[18:40] <DanielRichman> (is it windows XP?)
[18:40] <Laurenceb> I also have an xp pro disk, but the os on the other partition is xp home
[18:40] <DanielRichman> ok
[18:40] <Laurenceb> not familiar with password cracking... sorry
[18:41] <DanielRichman> well
[18:41] <DanielRichman> there's a package on ubuntu called ophcrack that makes it very easy]
[18:41] <Laurenceb> how does that help...?
[18:41] <DanielRichman> but you have to download a ~500mb rainbow table and hope that the password is alphanumeric
[18:41] <DanielRichman> besides, this is presuming that getting the admin password will help you fix it
[18:41] <DanielRichman> which I'm not sure about
[18:42] <DanielRichman> I can give you more info if you want... have the antivirus vendor said anything about a fix for bricked pcs?
[18:42] <DanielRichman> *has
[18:43] <Laurenceb> not that I'm aware of
[18:43] <Laurenceb> I'm not 100% sure its the problem
[18:43] <Laurenceb> but I read about it happening, and the dates match
[18:44] <DanielRichman> I guess repair is your best option then
[18:44] <DanielRichman> I mean, you can *try* and crack the admin password but I expect that it's probably a good password... and then you could hope that you can fix it using that... but the chance of success isn't high.
[18:45] <Laurenceb> right...
[18:45] <DanielRichman> Do you know which system files it deleted?
[18:45] <Laurenceb> I could look into the problem a bit more and see
[18:46] <DanielRichman> sorry
[18:46] <Laurenceb> http://www.theregister.co.uk/2009/06/09/mcafee_update_snafu/
[18:47] <DanielRichman> hmm. Maybe the mcafee forums are the place to go.
[18:47] <Laurenceb> yeah
[18:50] <DanielRichman> When do those euro laws about programmers being accountable for their bad code's damage come into effect... damn, now would be a good time
[18:50] <Laurenceb> cant find anythnig on their forum
[18:50] <Laurenceb> damn I dont have time for this bs
[18:51] <DanielRichman> Does your account have admin priveleges?
[18:52] <Laurenceb> I think so...
[18:52] <DanielRichman> You could try booting into safe mode
[18:52] <Laurenceb> already tried that
[18:52] <Laurenceb> it die after about half a second
[18:52] <DanielRichman> Who set up the laptop?
[18:52] <Laurenceb> *dies
[18:53] <Laurenceb> it came with windows installed
[18:53] <Laurenceb> I stuck ubuntu on anoth partition
[18:53] <DanielRichman> Ok... who forced the install of McAfee?
[18:53] <Laurenceb> and dont use windows very often
[18:53] <Laurenceb> its part of the rules for connecting to the network here

[18:53] <DanielRichman> so isn't everyone having the same problem?
[18:53] <Laurenceb> - yes.. I should have uninstalled it straight away :P
[18:53] <jcoxon> updates?
[18:54] <sbasuita> Surely the university has issued a fix?
[18:54] <Laurenceb> not that I've heard
[18:54] <sbasuita> go and complain
[18:54] <DanielRichman> so every single person in the uni has a bricked laptop
[18:54] <Laurenceb> lol
[18:54] <DanielRichman> If you have a deadline then you just found an excuse
[18:54] <DanielRichman> not that that helps ;)
[18:54] <Laurenceb> hehe
[18:54] <Laurenceb> it may be a matter of timing
[18:55] <DanielRichman> It came with windows installed.... was there a recovery disk or partition?
[18:55] <DanielRichman> where is that now?
[18:55] <Laurenceb> theres some weird "acer erecovery"
[18:55] <sbasuita> you can boot that?
[18:55] <Laurenceb> but it requires a password
[18:55] <Laurenceb> which I dont have
[18:55] <sbasuita> how come you don't have the passwords?
[18:55] <Laurenceb> *shrug*
[18:56] <Laurenceb> probably lost them
[18:56] <sbasuita> btw i would definitely give ophcrack a try for the windows passwords
[18:56] <sbasuita> it works very nicely
[18:56] <DanielRichman> sbasuita, you're painting a shady picture of the pair of us
[18:56] <DanielRichman> Laurenceb, you said you had an XP pro disk
[18:56] <Laurenceb> heh
[18:56] <Laurenceb> yes
[18:56] <DanielRichman> if you need windows _now_ then it only takes about 40 mins
[18:56] <sbasuita> 700mb of rainbow tables
[18:56] <DanielRichman> ok
[18:57] <DanielRichman> I lie.... about an hour and abit
[18:57] <sbasuita> then the crack is minutes
[18:57] <Laurenceb> hmm no I have some apps installed I wouldnt want to lose
[18:57] <DanielRichman> Make a third partition or install virtualbox (ubuntu)
[18:57] <DanielRichman> what do you need windows for?
[18:57] <sbasuita> wut?
[18:57] <sbasuita> oh right
[18:57] <Laurenceb> I already have a third partition

[18:58] <DanielRichman> Laurenceb, what do you need windows for?
[18:58] <Laurenceb> programming avrs
[18:58] <DanielRichman> what's up with avrdude & gcc?
[18:59] <Laurenceb> I need to update the firmware on my programmer
[18:59] <Laurenceb> and the app for updating it only runs on xp
[19:00] <sbasuita> wine?
[19:00] <sbasuita> I would check appdb
[19:00] <DanielRichman> pretty rare app
[19:00] <Laurenceb> doesnt work properly in wine
[19:00] <DanielRichman> and you don't wanna brick the thing
[19:00] <DanielRichman> well if you need hardware access to a programmer then virtual machine is out of the question
[19:00] <Laurenceb> the usb comms screw up in wine
[19:01] <sbasuita> go and shout at the it department
[19:01] <sbasuita> it's what they're there for
[19:01] <Laurenceb> heh
[19:01] <DanielRichman> so I recommend fourth partition ... or you could find a nearby helpful person with a working PC
[19:01] <Laurenceb> I really need to fix windows
[19:01] <Laurenceb> so I might as well solve both problems at once
[19:01] <DanielRichman> not if you really need windows now
[19:02] <Laurenceb> heh
[19:02] <DanielRichman> because it's gonna take a while

[19:20] <Laurenceb> problem is the goofy pin headers

[19:23] <Laurenceb> sbasuita: I'd prefer ARM7
[19:23] <Laurenceb> or at least something with a bit more hardware
[19:24] <sbasuita> then you can run ubuntu on your attitude sensors!
[19:24] <Laurenceb> couple of I2C units maybe
[19:24] <Laurenceb> ubuntu isnt real time
[19:24] <Laurenceb> but real time linux doesnt look too hard
[19:24] <sbasuita> there is a real time kernel
[19:24] <Laurenceb> porting it to AVR32 would be interesting
[19:25] <Laurenceb> SpeedEvil: their approach is very sub optimal, but it seems to work well enough

[19:29] <DanielRichman> sbasuita, break what
[19:30] <sbasuita> DanielRichman, it
[19:30] <Laurenceb> basically youd setup something to poll the sensors and compute a new attitude solution say every 10ms
[19:30] <DanielRichman> damn, that could be a lot of things
[19:31] <Laurenceb> you cant do that without a real time kernel
[19:31] <DanielRichman> so it's much faster at hardware access but suxx for multitasking?
[19:31] <Laurenceb> well your other tasks run as well
[19:32] <SpeedEvil> sucks is strong
[19:32] <Laurenceb> your kernel just schedules the real time task every 10ms
[19:32] <SpeedEvil> has a marginally higher overhead

[19:36] <sbasuita> DanielRichman, low latency a/v
[19:37] <Hiena> Actually the RT kernel gives much more reliability for the system. Also, it could prevent the stucked process eating up the resources.
[19:37] <sbasuita> yep
[19:40] <DanielRichman> sbasuita, it works. the power light comes on!
[19:40] <Hiena> It's a little but tight to desing, but pays on the several way. For example, possible to keep the other resources low for the processes. Can save a lot of buffer and gives a reliable GUI, which is no slow down, when other porcesses running.
[19:40] <sbasuita> DanielRichman, you've done the whole pcb now?

[20:43] <Laurenceb> can anyone explain how "repair install" is supposed to work?
[20:44] <DanielRichman> basically
[20:44] <DanielRichman> pop in the install disk
[20:44] <DanielRichman> it copies all the files again
[20:44] <DanielRichman> ie. overwrites all system files
[20:44] <DanielRichman> except for the stuff that makes your pc yours
[20:44] <Laurenceb> I dont think its detecting a previous os

[20:44] <Laurenceb> but if I try to install windoze it says theres a previous os on the partition
[20:44] <Laurenceb> yes
[20:45] <DanielRichman> even if you make a new partition with gparted
[20:45] <DanielRichman> and free it some space?
[20:45] <Laurenceb> I want to repair the installation
[20:46] <Laurenceb> boot -> setup windows -> accept license -> select installation -> start repair with r
[20:46] <Laurenceb> those are the instructions I found

[22:34] <jcoxon> while cocoamodem is a lot better (probably the best)
[22:34] <sbasuita> hmm i'll try that sometime
[22:35] <jcoxon> WB8ELK and I tested various programs while tracking PBH-9
[22:36] Laurenceb (n=laurence@dyres221-74.surrey.ac.uk) joined #highaltitude.
[22:36] <Laurenceb> hello
[22:36] <Laurenceb> balloon found?
[22:36] <jcoxon> and he is incredibly good at decoding by ear - managed to nearly match him with cocoamodem
[22:37] <Laurenceb> and developments?
[22:38] <jcoxon> nothing since you were last on
[22:38] <Laurenceb> i see
[22:38] <Laurenceb> still trying to work out how to fix my laptop
[22:38] <Laurenceb> is it possible to copy over the entire system32 folder?
[22:39] <jcoxon> doubt it
[22:39] <sbasuita> why not?
[22:40] <sbasuita> cocoamodem = max os x
[22:41] <jcoxon> sbasuita, indeed it does
[22:43] <Laurenceb> /media/VRMPOEM_EN/i386/system32
[22:43] <Laurenceb> theres only 2 files in there
[22:46] Action: sbasuita installs gmfsk
[22:49] Nick change: KingJ -> kingj

[23:02] <Laurenceb> hmm I cant work out how its all arranged :-/
[23:02] <sbasuita> well... there are only two files to arrange....
[23:03] <Laurenceb> oh
[23:03] <Laurenceb> what, stick them in system32?
[23:03] <sbasuita> yeh
[23:03] <sbasuita> aren't they already there?
[23:03] <Laurenceb> I'll check
[23:03] <sbasuita> ooho
[23:03] Action: sbasuita spots a haribo on his desk
[23:03] <sbasuita> say goodbye
[23:04] <sbasuita> anyway
[23:04] <sbasuita> i'm off for today
[23:04] <sbasuita> Laurenceb, good luck with windows
[23:04] <Laurenceb> thanks
[23:04] <Laurenceb> cya
[23:04] sbasuita (n=sbasuita@unaffiliated/drebellion) left irc: "Leaving"
[23:25] <Laurenceb> this was a stupid idea
[23:29] <SpeedEvil> ?
[23:30] <Laurenceb> trying to copy over the folders
[23:31] <SpeedEvil> ah
[23:32] <Laurenceb> http://gentlenav.googlecode.com/files/DCMDraft2.pdf
[23:34] jcoxon (n=jcoxon@217.39.7.252) left irc: Read error: 110 (Connection timed out)
[23:46] <Laurenceb> its a bit of a fudge
[23:46] <Laurenceb> but probably works quite well
[23:47] <Laurenceb> most of your error is going to be due to gyro bias drift - especially for cheap gyros
[23:48] Action: SpeedEvil is not doing any more thinking today - been digging and landscaping and stuff.
[23:48] <Laurenceb> :P
[23:49] <SpeedEvil> any progress on rocket stuff
[23:50] <Laurenceb> it needs an IMU :P
[23:50] <SpeedEvil> ah
[23:51] <SpeedEvil> magnetometer + sun sensor
[23:51] <Laurenceb> the AD one should work
[23:52] <SpeedEvil> Oh - the ST parts - the dual axis gyros - aren't sampleable. (nor are the one axes)
