[19:06] <jcoxon> evening all
[19:06] <jcoxon> internet finally back on
[19:06] <rocketboy> hiya
[19:07] <rocketboy> I had a problem with mine 2
[19:07] <jcoxon> oh the internet - was worried that was the payload you were talking about
[19:07] <jcoxon> everything set for tomorrow?
[19:08] <rocketboy> still got a few things to do
[19:08] <rocketboy> we will need a 54" chute for 1.7Kg - so I'll have to adapt my one
[19:08] <rocketboy> I may leave it until tomorrrow
[19:08] <jcoxon> okay
[19:09] <jcoxon> i've got a 36" and also a bottle top
[19:09] <jcoxon> i've also emailed the cambridge wireless soc about borrowing a receiver
[19:09] <rocketboy> yeah - well we could use that but it will be a fast descent
[19:10] <jcoxon> okay
[19:10] <jcoxon> your one is fine
[19:10] <jcoxon> i haven't made a radar reflector
[19:11] <jcoxon> got dragged away today so haven't been around
[19:12] <rocketboy> no probs
[19:12] <jcoxon> stream looks good
[19:12] <jcoxon> right i'm returning officer for our jcr elections
[19:12] <rocketboy> yeah
[19:13] <jcoxon> so i'm in the middle of the count
[19:13] <jcoxon> so will be back and forth
[19:13] <rocketboy> do you know how big henry has made the cut-down radius
[19:13] <rocketboy> ?
[19:22] <jcoxon> nope
[19:22] <jcoxon> oh wait yes
[19:23] <jcoxon> 50km distance
[19:23] <jcoxon> 3 hours
[19:23] <jcoxon> 31km alt
[19:23] <rocketboy> ok - will check against mu cutdown square
[19:23] <rocketboy> my
[19:25] <rocketboy> humm according to my burst predictor the balloon will burdt 1st
[19:25] <rocketboy> burst
[19:26] <rocketboy> mind you its not 100% accurate
[19:26] <jcoxon> hmm he's on msn
[19:27] <jcoxon> i'll se
[19:27] <jcoxon> speak to him
[19:27] <jcoxon> actually i'll get him on here
[19:27] <rocketboy> he may have a better estimate

[19:32] <hmh33> evening
[19:33] <rocketboy> hi henry
[19:33] <hmh33> how's it going?
[19:34] <rocketboy> no bad - just finishing up here and there
[19:34] <rocketboy> re burst altitude - I did a calcualtion on burst and made it 30,200m
[19:34] <hmh33> hm
[19:34] <rocketboy> based on carrying 1.7Kg
[19:35] <hmh33> perhaps we should cut down early then
[19:35] <hmh33> one sec
[19:35] <rocketboy> and 320m/min acsent rate (1.3Kg exccess lift)
[19:35] <hmh33> ok
[19:35] <hmh33> well
[19:36] <hmh33> my new fancy GPS quotes 18km as the max altitude for COCOM
[19:36] <hmh33> so anything above that should be fine to test what its behaviour is
[19:36] <rocketboy> I don't mind either way - but if you want to tst your cutdown
[19:36] <hmh33> shall we make it 25km?
[19:36] <rocketboy> yeah that should be fine
[19:36] <hmh33> ok, will do
[19:37] <rocketboy> have you set the cutdown radius to 50Km?
[19:38] <hmh33> yep
[19:38] <hmh33> easy to change though
[19:38] <rocketboy> ok -I'll adjust my cutdown accordingly
[19:38] <hmh33> 50km distance, 25km altitude, 3 hours
[19:39] <rocketboy> ta
[19:48] <rocketboy> have you got a radio -audio lead (I cant find mine)
[19:49] <rocketboy> bb shortly
[20:04] <phatmonkey> jcoxon, went down with a fluey cold thing last night, right bummer
[20:05] <phatmonkey> i probably won't be there tomorrow, but if you could PM me your mobile, i'll ring you tomorrow morning if i'm feeling any better
[20:05] <phatmonkey> i'll bring my 60" chute too
[20:10] <rocketboy> have found my audio lead in the car boot - so no probs
[20:12] <jcoxon> phatmonkey, okay doing it now
[20:34] <hmh33> rocketboy, your GSM is working, right?
[20:35] <hmh33> I'm thinking of not flying a phone with Tracker 4 because of weight and having dropped the only decent phone we have into the sea, it's proving a right pain to get the other one working
[20:50] <jcoxon> henry - i've got a nokia 5110
[20:51] <jcoxon> just sitting on my desk

[20:59] <laurenceb> Hi all
[21:00] <laurenceb> I'll be catching the train into Cambridge for 9.02
[21:00] <laurenceb> tomorrow morning
[21:01] <rocketboy> I don't 100% trust my phone -its been working recently - but its had periods when its stopped
[21:01] <laurenceb> I could walk from the station to Catz or somewhere but it'd take a while
[21:01] <laurenceb> could anyone pick me up?
[21:02] <laurenceb> rocketboy- are you using mbus?
[21:03] <rocketboy> na Fbus
[21:03] <laurenceb> I always turn the phone on after the flight computer, micros can spit out some junk as they turn on
[21:03] <rocketboy> I think the problem is power sequencing
[21:03] <laurenceb> or AVRs can probably a dodgy power switch
[21:03] <rocketboy> yeah - I was just about to say that
[21:04] <rocketboy> U can have a lift BTW
[21:04] <laurenceb> with serial at commands at least it can crash the phone
[21:04] <rocketboy> where from? and when?
[21:04] <laurenceb> ok thanx
[21:05] <laurenceb> cambridge station at 9.02 to whereever we're meeting
[21:05] <laurenceb> the train I'm catching is from london
[21:06] <rocketboy> sure - no probs U know my mob no. ?
[21:06] <laurenceb> erm think so but havnt got my phone on me, seem to remember you emailed it to me before
[21:07] <laurenceb> hmm yes I'm sure you did
[21:07] <laurenceb> I didn't realise we could get so high, 31km would be awsome
[21:08] <rocketboy> OK - text if things change
[21:08] <laurenceb> sure thanx
[21:08] <laurenceb> I'm worried my camera wont make it to full altitude tho
[21:09] <laurenceb> earlier I did some experiments, and it looks like at 31km I will have used 1.13Ah
[21:09] <laurenceb> batteries are 1.25Ah
[21:09] <laurenceb> but they will get cold
[21:10] <laurenceb> altho the smps on the camera can "suck" everything out of the batteries, and the payload uses 3 watts
[21:11] <laurenceb> just have to see what happens, I was even worried it could overheat, the processor could reach 90C according to some rough estimates
[21:13] <laurenceb> Was thinking of making a double glazed cling film window for the camera, but I've forgotten to get any, will look around...
[21:32] <laurenceb> Okay I'd better be of cya all tomorrow
[21:42] <hmh33> nice Laurence, see you soon
[21:42] <hmh33> night*
[21:44] <laurenceb> miaw purrrrrr....
[21:45] <laurenceb> ok I really am off now cya

[23:12] <jcoxon> right i'm back for good now
[23:15] <jcoxon> actually looking rather good for tomorrow
[23:16] <jcoxon> right got an email back from CU wireless soc
[23:16] <jcoxon> they forwarded my email
[23:16] <jcoxon> basically it seems that none of them are around
[23:16] <jcoxon> but if we gave them a bit of warning then they would be more then happy to hlep
[23:16] <jcoxon> help*
[23:22] <jcoxon> rocketboy, what time are you planning to arrive?
[23:22] <rocketboy> about 9 to pick up laurence
[23:23] <jcoxon> okay cool
[23:23] <jcoxon> about the scanners - none seem to have SSB (as you said)
[23:23] <jcoxon> would they work at all?
[23:24] <jcoxon> e.g. with CW
[23:25] <rocketboy> no you normally need ssb for cw or ssb
[23:25] <jcoxon> right okay
[23:26] <jcoxon> we'll just have to make do
[23:28] <rikstah> ahh SHIT man
[23:28] <rikstah> i forgot to patch one of my cacti installations, and someone has sploited my box
[23:28] <jcoxon> rikstah, rubbish
[23:28] <rikstah> found some random binaries here
[23:29] <rikstah> and some backdoor perl script that spawns a shell
[23:29] <rikstah> jcoxon ?
[23:29] <jcoxon> lucky you found it
[23:29] <jcoxon> oh sorry by rubbish i mean thats bad
[23:29] <rikstah> yeah, totally
[23:30] <jcoxon> its a little bit of a northern phrase
[23:30] <rikstah> haha im from manchester :)
[23:30] <jcoxon> hehe my friends from doncaster always say "rubbish"
[23:30] <jcoxon> its sort of stuck
[23:31] <rikstah> we say "that's rubbish"
[23:31] <rikstah> but just rubbish would mean like....bullshit
[23:31] <jcoxon> hehe i think "thats" just been dropped
[23:31] <rikstah> yeah
[23:31] <rikstah> any launches soon?
[23:32] <rikstah> al murray is a legend (itv)
[23:34] <jcoxon> rikstah, we're launching tomorrow
[23:34] <rikstah> sweet, what is it?
[23:34] <rikstah> any info on website?
[23:35] <jcoxon> ummm the launch page is:
[23:35] <jcoxon> http://wiki.ukhas.org.uk/ukhas_1
[23:35] #highaltitude: mode change '+o jcoxon' by ChanServ!ChanServ@services.
[23:36] <rikstah> no camera?
[23:36] Topic changed on #highaltitude by jcoxon!n=jcoxon@jac208.caths.cam.ac.uk: Welcome to #highaltitude - discuss anything to do with high altitude projects (balloons, gliders, etc) see http://www.ukhas.org.uk and the wiki: http://wiki.ukhas.org.uk , Launch of UKHAS 1 - Sat 3rd Feb 10.30am, more info http://wiki.ukhas.org.uk/ukhas_1
[23:36] <jcoxon> XABEN1 and MiHAB 3 have cameras
[23:37] <rikstah> exciting
[23:37] <rikstah> i'd come to one but its pretty far
[23:38] <rikstah> cost me 100 quid in petrol
[23:38] <jcoxon> hopefully i might be able to set up internet tomorrow to the site
[23:38] <jcoxon> so will be able to do some online tracking stuff
[23:38] <rikstah> nice
[23:38] <rikstah> how long is the flight
[23:39] <jcoxon> about 2 hours
[23:39] <rikstah> cool, thats a pretty big payload
[23:39] <jcoxon> its a fair size
[23:39] <jcoxon> the weather is excellent
[23:40] <jcoxon> so shouldn't go far
[23:40] <rikstah> wicked
[23:40] <rikstah> i'll get up for it
[23:40] <rikstah> the comms is always what i am impressed with
[23:40] <jcoxon> not promising about hte internet though
[23:41] <jcoxon> we've been trying to find another radio to track with
[23:41] <jcoxon> sadly all avenues have failed
[23:41] <rikstah> yeah, it's tough
[23:43] <rikstah> does it get to like -50 C up there?
[23:43] <jcoxon> really wish we had a second radio - would love to also track it from the launch site
[23:43] <jcoxon> yup
[23:43] <jcoxon> v. cold
[23:43] <jcoxon> not sure if anyone is flying a temp sensor
[23:43] <rikstah> surprised stuff still functions at that temp
[23:44] <rikstah> does that degrade the batteries too?
[23:44] <jcoxon> the batteries certainly suffer
[23:44] <jcoxon> however we use lithiums which are tougher
[23:44] <jcoxon> also the insulation of hte case will certainly help
[23:44] <rikstah> it's pretty impressive
[23:44] <rikstah> any gumstix flying? :)
[23:45] <jcoxon> not tomorrow
[23:45] <jcoxon> trying to be sensible and not rush things
[23:45] <rikstah> i liked that curses based tracking software screenshot i saw
[23:45] <rikstah> dont know what payload it was for
[23:45] <jcoxon> one of ours?
[23:46] <rikstah> i dunno, was a while ago
[23:46] <rikstah> looked cool though
[23:47] <jcoxon> i'm planning to use google earth
[23:48] <rikstah> yeah sure
[23:49] <jcoxon> right i better get some sleep
[23:49] <jcoxon> night all, see some of you tomorrow
[23:49] <rikstah> night
