[09:22] <edmoore> morning jcoxon
[09:30] <jcoxon> hey edmoore
[09:30] <edmoore> yo
[09:30] <jcoxon> hows tricks?
[09:35] <edmoore> not bad
[09:36] <edmoore> going to do my ham practicals today
[09:37] <jcoxon> oh cool
[09:38] <jcoxon> get to make some contacts then
[09:38] <jcoxon> who is the course with?
[09:39] <edmoore> cu wireless
[09:39] <edmoore> they're semi-loaning their traking head to us aswell
[09:39] <edmoore> which will be awesome
[09:39] Action: jcoxon is jealous :-)
[09:39] <edmoore> it will be on the web for all to play with :)
[09:40] <jcoxon> edmoore, i reckon you'll really like HF
[09:41] <edmoore> me too
[09:41] <jcoxon> hehe i still haven't made a contact on 70cm - its such a dead band
[09:41] <jcoxon> i can hear 3 repeaters but can't do CTCSS so can't transmit to them
[09:43] <edmoore> that's why I like 70cm. never heard a thing on it other than us when HABbing
[09:44] <jcoxon> one day i'll get a 2m rig
[09:44] <jcoxon> i can't do HF, just don't have the antenna space
[09:44] <edmoore> i'm just waiting for when I can get the ic-7000
[09:44] <jcoxon> hehe
[09:44] <jcoxon> woohoo, got packet radio working really nicely
[09:45] <edmoore> oh grand
[09:45] <edmoore> i am looking forward to this beastie going up
[09:45] <jcoxon> actually its not packet
[09:45] <jcoxon> its rrt
[09:45] <jcoxon> rtty*
[09:46] <jcoxon> genius code from rocketboy - rtty/packet/fm/ssb/different baud/callsigns/ etc
[09:46] <jcoxon> all in one binary
[09:47] <edmoore> awesome :)
[09:48] <jcoxon> now to sort the sstv bit and then i'm done

[10:07] <rjharrison> At the ball park with the kids
[10:08] <rjharrison> Being a good parent taking the asus with me ;)
[10:09] Action: rjharrison testing
[10:10] <jcoxon> haha
[10:12] <rjharrison> I was the first person here. In fact we still are the only family here
[10:13] <jcoxon> sounds fun!
[10:13] Action: jcoxon is doing research for an essay
[10:14] <rjharrison> What is the essay on
[10:14] <jcoxon> Photo dynamic therapy
[10:14] <rjharrison> Is that the one for your prof.
[10:15] <jcoxon> what do you mean?
[10:17] <jcoxon> its for a professor
[10:17] <jcoxon> i was meant to have started it weeks ago
[10:17] <jcoxon> oh well :-)
[10:21] <rjharrison> I remember you saying on here that he asked you to write one
[10:21] <rjharrison> I can't remember what it was about now
[10:21] <rjharrison> breast cancer tretmnet?
[10:21] <rjharrison> treatment
[10:22] <jcoxon> oh its the same one
[10:22] <rjharrison> Oh i c above
[10:22] <rjharrison> opps
[10:23] <rjharrison> I'm going to write up the launch tonight. When the kids are down. It will take a couple of hours
[10:24] <jcoxon> sounds good
[10:28] <jcoxon> i'm also sorting out sstv
[10:28] <jcoxon> nearly done
[10:28] <rjharrison> I may suggest that we populate a table on the wiki for launches as it would be a good reference when trying to compare stats
[10:28] <rjharrison> I'm impressed jc can you do two things at once
[10:29] <rjharrison> I'v had my suspicions for a while
[10:29] <jcoxon> ummm, the wiki idea is great
[10:29] <jcoxon> i'm not sure how much data is around/if people have time to go over their old data
[10:29] <jcoxon> but certainly start a table and we can add to it
[10:30] <jcoxon> there is alread the list of launches data table
[10:30] <rjharrison> well I can make a start and see how it goes
[10:30] <jcoxon> i can semi do 2 things at once
[10:30] <jcoxon> i set things off to run and then carry on working
[10:30] <rjharrison> :) parallel architecture
[10:31] <jcoxon> it helps that they aren't related
[10:31] <jcoxon> so its easy to seperate them
[10:33] <rjharrison> My distraction is not work it's three lovely noisy demanding children
[10:34] <jcoxon> bless :-)
[10:34] <rjharrison> 8 5 and 1 Faye Charlie and Jack respectivly
[10:35] <rjharrison> I'm reasearching payload cutdown
[10:35] <rjharrison> Funny how important that becomes after your first near drop in the sea
[10:37] <jcoxon> its a tough one to get right
[10:43] <rjharrison> Obv. There are going to be some boundries set up and I need to consider either explosive or hotwire cutter type
[10:43] <jcoxon> yup
[10:43] <jcoxon> in the US they use hotwire
[10:44] <jcoxon> here we've used explosive
[10:44] <rjharrison> I'm thinking using a loop of thin kite string placing it around a hot wire in a cardboard tube
[10:48] <rjharrison> To prevent any damage to chute. Then initially i plan to drop out using the gps at a fixed alt of 32k or a drop of 100m
[10:48] <jcoxon> yeah that sound sensible
[10:59] <jcoxon> right, got that all working
[10:59] <rjharrison> I'll look at the accelerometer stuff after i have some success with the cutdown. I'm thinking that this tech would be better but will require alot more testing
[10:59] <jcoxon> 40 cycles of rtty at 300baud then transmits the sstv image
[10:59] <jcoxon> repeat...
[11:00] <rjharrison> woof 300 baud. I want that bandwidth
[11:01] <jcoxon> i can vary it if i want
[11:01] <rjharrison> I'm going to move to rtty for the next launch I'm sure i can make the circuit
[11:01] <jcoxon> but we haven't really noticed any difference between 50 and 300

[13:25] <Hiena> Hi all!
[13:25] <Hiena> I have a research idea.
[13:26] <Hiena> But for this one need the double balloon launch.

[13:38] Nick change: Polir -> Hiena
[13:55] <EI5GTB__> Hiena, whats that?
[13:56] <Hiena> HA sound speed measurement.
[13:56] <Hiena> One balloon has emitter, the another one has a receiver.
[13:58] <Hiena> Both balloon has a synced onboard clock, and gps. Every few seconds one balloon "ping" the other one.
[13:59] <SpeedEvil> Acetylene+oxygen balloons'd work well for that.
[13:59] <SpeedEvil> To quote Sean Connery - One ping only.
[14:00] <SpeedEvil> It would also be an alternate cut-down mechanism.
[14:00] <Hiena> Yeah, but such experiment highly illegal here.
[14:00] <SpeedEvil> Meh.
[14:01] <SpeedEvil> They won't let us do anything fun :(
[14:01] <SpeedEvil> I had the best idea for fireworks, using small nuclear explosions, with doped fireballs, so they go into pretty colours.

[14:27] <rjharrison> Ok I want to make a hot wire cut down using a 9v battery can I uase a large cap to make the wire white hot?
[14:30] <Hiena> Nope.
[14:30] <Hiena> Not enough capacity.
[14:31] <Hiena> Use some pyro and a small wire.
[14:32] <Hiena> Or boost the output voltage level for the capacitor.
[14:33] <rjharrison> Ok thanks for that. Desktop tests show 9v too low
[14:34] SpikeUK (n=chatzill@host86-136-203-59.range86-136.btcentralplus.com) joined #highaltitude.
[14:35] <Hiena> For a hindsight 1F=1 Coulomb = 1 A*s => The rough max power of the charge (U/2)*C
[14:36] <Hiena> You could measure the the needed power on the desktop test.
[14:37] <Hiena> And from this test you could estimate the needed voltage and capacity.
[14:37] <jnd> 1/2*U*U*C is the power of capacitor
[14:38] <Hiena> Keep in mind, at low temperature need more energy for the cutoff.
[14:39] <rjharrison> I think it will have to be pyro and ideas for ignition
[14:39] <rjharrison> SpeedEvil usually has a few ideas on these
[14:40] <Hiena> Hopes not nuclear powered. ;)
[14:42] <jnd> no, nucular power :p
[14:45] <SpikeUK> rjharrison - how about model rocket fuses?
[14:50] rouslan (n=rouslan@pool-64-222-183-17.man.east.verizon.net) joined #highaltitude.
[14:53] <SpikeUK> I used to use Jetex rocket motors as a kid and often wondered if the fuse wire could be triggered electrically
[14:53] <SpeedEvil> rjharrison: inexpensive resistors rated to 350C are available.
[14:53] <SpeedEvil> rjharrison: you can use those to cut tape.
[14:56] <SpeedEvil> http://uk.farnell.com/1462369/passives/product.us0?sku=ohmite-ox473ke forex
[14:56] <SpeedEvil> (though that is 220C only)
[14:56] <SpeedEvil> whch will work just fine for most stuff.
[15:19] <rjharrison> SpeedEvil what kind of voltage do I need?
[15:19] <rjharrison> 9v ok
[15:19] <rjharrison> pp3
[15:28] <SpeedEvil> It depends.
[15:28] <SpeedEvil> I don't know what current you can reliably get out of a half-dead battery at -40C
[15:29] <SpeedEvil> PE tape will basically melt at 130C

[17:28] <Laurenceb> easy to build and you can test them as much as you want

[18:39] <rjharrison> Laurenceb: I'm very interested in your resistor cutter
[18:39] <rjharrison> Would that work from a 9v supply
[18:39] <Laurenceb> I'm not sure if theres any photos on the wiki
[18:39] <Laurenceb> maybe I should make a page for it
[18:39] <rjharrison> Thinking PP3 battery here
[18:39] <rjharrison> :)
[18:39] <Laurenceb> that wouldnt work very well
[18:40] <Laurenceb> 9V is too high
[18:40] <Laurenceb> it would incinerate the resistor
[18:40] <rjharrison> How much voltage would it need. Thinking balloon here
[18:40] <rjharrison> Good
[18:40] <rjharrison> Less then
[18:40] <Laurenceb> and 9V cells have high impedance
[18:40] <SpeedEvil> you can use any voltage
[18:40] <Laurenceb> I use about 5V
[18:40] <SpeedEvil> wattage is the important thing.
[18:40] <Laurenceb> yeah
[18:40] <SpeedEvil> You just adjust the resistor value to be appropriate.
[18:40] <rjharrison> True true
[18:40] <Laurenceb> its a matter of getting it right
[18:41] <SpeedEvil> I ahve some doubts that half-drained 9V at -40C is gonna supply useful power.
[18:41] <Laurenceb> I'm using 10ohm resistors at 8volts
[18:41] <Laurenceb> for the mini rogallo
[18:41] <Laurenceb> 0.125 watt ones
[18:42] <rjharrison> How hot do them buggers get?
[18:42] <rjharrison> approx
[18:42] <Laurenceb> ~350C
[18:43] <Laurenceb> you could try with a pp3, but I dont think you could make it work
[18:43] <Laurenceb> I'd try the same setup with 4xAAA or AA
[18:44] <rjharrison> That is eminantly doable
[18:44] <Laurenceb> you need to get the resistor above about 200C to be sure its going to work at altitude
[18:44] <SpeedEvil> Look at the derating curves, and you can infer the case temp.
[18:44] <Laurenceb> but if you go much above 350 or so they burn out very fast
[18:45] <Laurenceb> power dissapation = V^2/R
[18:45] <Laurenceb> so it goes up very fast with V
[18:45] <rjharrison> Im thinking hotmelt glue in a tube with resistor heating it and releasing line
[18:46] <SpeedEvil> rjharrison: some insulation, and that cna use very low power
[18:46] <Laurenceb> you dont have much power output
[18:46] <rjharrison> Ok Laurenceb: thanks for that and SpeedEvil for input
[18:46] <Laurenceb> so you need to heat something small
[18:46] <SpeedEvil> 5mm or so wide tape round a resistor works well
[18:46] <Laurenceb> I loop tape round the resistor
[18:46] <SpeedEvil> bury it in a scrap of fibreglass insulation
[18:46] <Laurenceb> yeah
[18:47] <Laurenceb> I tried with 1206 smd ones but it melts the solder
[18:47] <rjharrison> what tape do you use?
[18:47] <Laurenceb> black insulating tape
[18:47] <SpeedEvil> rjharrison: any polythene tape is good
[18:48] <SpeedEvil> rjharrison: you just want it to be strong enough, and melt at lowish temps.
[18:48] <SpeedEvil> rjharrison: it's not really critical.
[18:48] <rjharrison> Testing will sort that out. I was wondering if braided kite cord would work
[18:49] <Laurenceb> it has quite a high melting point
[18:49] <Laurenceb> you'll be on the verge of burnig out the resistor
[18:49] <rjharrison> and how do you trun this on and off?
[18:49] <rjharrison> turn
[18:49] <rjharrison> realy
[18:49] <SpeedEvil> FET

[20:20] <natrium42> i didn't find one, sorry
[20:20] <rjharrison> natrium42 uv to keep the box warm
[20:21] <rjharrison> just to seal from the elements
[20:21] <natrium42> makes sense
[20:22] <natrium42> rjharrison, how did you check the lift?
[20:22] <rjharrison> With my arm :)
[20:22] <natrium42> i see that you inflated the balloon directly from nozzle
[20:22] <rjharrison> :D Bit crap rally but it was windy
[20:22] <rjharrison> and i was on my own initially
[20:22] <natrium42> hehe
[20:22] <rjharrison> Got my mum and her husband to come and help
[20:22] <natrium42> do you know what the ascent rate was?
[20:23] <rjharrison> rally = really
[20:23] <natrium42> it's good to have help :)
[20:23] <rjharrison> The stats are here http://www.robertharrison.org/index.php?option=com_content&task=view&id=35&Itemid=78
[20:24] <natrium42> cool, thanks
[20:24] <rjharrison> The tracker has the data loaded check out the google earth to see the mirical landing
[20:24] <rjharrison> URL comming up
[20:25] <natrium42> oh, i think i have it
[20:25] <rjharrison> http://www.robertharrison.org/index.php?option=com_content&task=view&id=35&Itemid=78
[20:25] <rjharrison> opps
[20:25] <natrium42> didn't check gearth yet, though
[20:25] <rjharrison> http://www.robertharrison.org/tracker/
[20:26] <RocketBoy> :-( about N9
[20:26] <RocketBoy> :-) rjharrison
[20:27] <rjharrison> Thanks RocketBoy
[20:27] <RocketBoy> jcoxon: :-) on the SSTV and packet - when do U think U will launch it?
[20:27] <rjharrison> I ended up rushing it on Friday rather than waiting till sat due to the weather
[20:27] <natrium42> so a bit slow accent rate
[20:27] <natrium42> but it resulted in a record, so :)
[20:28] <rjharrison> But so nearly lost it
[20:28] <rjharrison> I would have given anything to have had it burst earlier at one point
[20:28] <natrium42> perhaps it would be a good idea to measure lift the next launch
[20:29] <rjharrison> Obv. quite please with my beginners luck in the end
[20:30] <rjharrison> Payload cut down and getting computer to geep sending the last gps coords even if it can't get new ones are the priority upgrades for ICARUS II
[20:30] <rjharrison> geep = keep
[20:32] <jnd> please replace the nbsp; with Technical Data :)
[20:32] <rjharrison> Intresting thing was is that the GPS locked out on impact and kept tx the same sentances to the flight comp which then tx'ed them out. The usual behavoiur was when the GPS sig was lost it tx'ed just icarus in morse. So another helpful consequence of something going wrong
[20:33] <rjharrison> The stats page is knackered
[20:35] <rjharrison> will sord
[20:35] <rjharrison> sort
[20:35] <RocketBoy> IMG_0435_RJH - is that the wash?
[20:36] <rjharrison> yep with some processing
[20:49] <Laurenceb> IMG_6046 whats the IC ?
[20:51] <jnd> atmega
[20:51] <Laurenceb> ah cool
[20:51] <Laurenceb> I thought you were using mega32?
[20:56] <rjharrison> atmega8
[20:56] <rjharrison> :)
[20:57] <rjharrison> 5v
[20:57] <rjharrison> no occilator
[20:57] <rjharrison> well internal
[20:57] <rjharrison> basic. This was just a test launch
[20:57] <Laurenceb> hmm
[20:57] <Laurenceb> I'd be careful using internal
[20:57] <Laurenceb> still, it seems to have worked
[20:57] <rjharrison> So I gather
[20:58] <rjharrison> Why are they so bad
[20:58] <rjharrison> Are they just for emergency?
[20:58] <Laurenceb> they drift with temperature
[20:58] <rjharrison> Ie get slower?
[20:58] <jnd> I've seen crystal oscillators stop in low temperature
[20:58] <Laurenceb> yeah
[20:59] <rjharrison> I guess I was doing so little processing it didn't matter
[20:59] <Laurenceb> they can, but for a uart you need fairly low drift
[20:59] <rjharrison> I'm guessing that the temp in the box would have been about +10c
[20:59] <jnd> do you use watchdog?
[20:59] <Laurenceb> so we've always used crystals
[20:59] <rjharrison> it was well sealed from the elements
[20:59] <RocketBoy> crystals - depend on how the crystal is "cut" (etched)
[20:59] <rjharrison> Laurenceb: Sorry I can't place you are you CUSF
[21:00] <Laurenceb> no
[21:00] <Laurenceb> I'm the random guy
[21:00] <RocketBoy> the tempreture sensitivity is all depenatant on the orientaion of the rystal lattice
[21:00] <Laurenceb> I'm a phd student at university of surrey atm
[21:00] <RocketBoy> BBL
[21:01] <jnd> what do you study?
[21:01] <Laurenceb> well i'm looking at gnss for atmospheric sounding
[21:02] <rjharrison> Cool
[21:02] <Laurenceb> gnss=global positioning satellite systems
[21:02] <rjharrison> I'm random too well less random these days.
[21:02] <Laurenceb> :P yeah v well done with the flight
[21:02] <Laurenceb> the pictures are amazing
[21:02] <rjharrison> I brought an RC copter last may and thought it would be fun to put a cam on it
[21:02] <Laurenceb> hehe
[21:03] <Laurenceb> I mant to make one autonomous
[21:03] <jnd> do you have video?
[21:03] <jnd> I've seen one very good
[21:03] <rjharrison> Yep loads on http://www.robertharrison.org/files/icarus
[21:03] <rjharrison> Then thought a balloon would be better than a copter
[21:04] <jnd> how do you call that thing with 4 rotors?
[21:04] <rjharrison> tehtered balloon and then wondered what would happen if you cut the teather
[21:04] <Laurenceb> quad rotor
[21:04] <Laurenceb> rjharrison: v neat idea for the ant
[21:04] <rjharrison> I then stumbled on natrium42's website when googleing
[21:04] <Laurenceb> I've been struggling to design the antenna for my mini rogallo
[21:04] <rjharrison> and he pointed me here
[21:05] <rjharrison> helecopter
[21:05] <rjharrison> helicopter jnd
[21:05] <Laurenceb> with 4 rotors its a quad rotor
[21:05] <rjharrison> ahh
[21:05] <Laurenceb> they are a pain to control
[21:05] <jnd> quadcopter maybe
[21:06] <rjharrison> Laurenceb the ground plane antenna?
[21:06] <jnd> mikrokopter is one german version
[21:06] <Laurenceb> your use of a bulkhead connector
[21:06] <Laurenceb> is clever
[21:09] <rjharrison> I think lucky, I tried not to bend the active and ground wires too much as someone said it wasn't good for them
[21:09] <rjharrison> Oh you mean the bit for the gound plane
[21:09] <rjharrison> Yep I thought that was clever too
[21:09] <Laurenceb> yeah
[21:10] <Laurenceb> :D
[21:10] <rjharrison> Made it just as easy as solering on the lenghts of copper wire striped from twin core and earth
[21:11] <rjharrison> Those bulkhead connectors (is that what they are called) what are they for
[21:11] <rjharrison> Seemed perfect design for GP construction
[21:12] <rjharrison> edmoore: You have any thoughts on payload cutdowns
[21:13] SpikeUK (n=chatzill@host86-136-203-59.range86-136.btcentralplus.com) left irc: "ChatZilla 0.9.83 [Firefox 3.0.3/2008092417]"
[21:17] <Laurenceb> it doesnt really solve my problem...
[21:18] <Laurenceb> I have about 15mm between the sma connector on my radio and the bottom of the payload enclosure
[21:18] <Laurenceb> I'll probably mount an sma adaptor onto the end of some coax
[21:18] <Laurenceb> then solder the shield onto copper foil
[21:18] <Laurenceb> RocketBoy: you about?

[22:13] <jnd> (23:43:58) jcoxon: ping gordonjcp
[22:13] <jnd> 23.5 hrs ago
[22:13] <Laurenceb> hi Rocketboy
[22:13] <RocketBoy> YO
[22:14] <jnd> do you still have summer time?
[22:14] <jnd> or Daylight saving time
[22:15] <RocketBoy> until next weekend
[22:17] <RocketBoy> jnd - so your not on daylight saving time?
[22:18] <jnd> I found its same in most of europe
[22:18] <RocketBoy> and your in the US?
[22:18] <jnd> no
[22:18] <RocketBoy> where?
[22:18] <jnd> czech rep
[22:19] <RocketBoy> its should be alinged europe wided - I thought the US aligned with europe some years ago
[22:19] <RocketBoy> IIRC
[22:19] <jnd> I wasn't sure if its same in the UK
[22:20] <jnd> so I am constantly 1 hour ahead
[22:20] <RocketBoy> yes even the changeover is now syncronised
[22:21] <RocketBoy> about 2/3am here 1/2am in the rest of europe IIRC
[22:22] <jnd> we have 2/3 too
[22:24] <jnd> or wait I'll check
[22:24] <natrium42> rjharrison, sup?
[22:25] <jnd> yes, 2/3
[22:26] <jnd> great, one more hour of sleep which they stole in spring
[22:31] <rjharrison> natrium42 thanks for coming back
[22:31] <jnd> /night
[22:31] <rjharrison> I want to have a go at the panorama can you tell me what the s/w is called
[22:31] <rjharrison> can I add to the one you have already done?
[22:34] <natrium42> sure
[22:34] <natrium42> kolor autopano pro
[22:34] <natrium42> they have a trial which stamps some text onto the render
[22:35] <natrium42> also, i used vdub to get video frames to .png files
[22:35] <rjharrison> Do U have the none trial or did you do something cleaver
[22:35] <rjharrison> humm this isn't going to be a quick operation
[22:36] <rjharrison> You did a great one yesterday. I think I found a couple more images to add
[22:38] <natrium42> yah, i have the full one
[22:39] <natrium42> it's reasonably priced
[22:39] <natrium42> maybe you can get rid of their text via photoshop once you render it...
[22:40] <natrium42> there are also some free tools that people use, but they seemed much harder to use
[22:43] <edmoore> jcoxon:
[22:43] <edmoore> is it daylight saving?
[22:43] <jcoxon> ?
[22:43] <jcoxon> don't think so
[22:44] <edmoore> ok, got confused
[22:45] <Laurenceb> next weekend?
[22:45] <RocketBoy> its daylight saving time now (BST)
[22:46] <Laurenceb> :P
[22:46] <RocketBoy> and BST next saturday GMT next sunday
[22:46] <Laurenceb> I was thinking when the clocks change over
[22:47] <RocketBoy> yeah - next weekend about 2am on the Sunday

[23:33] <Laurenceb> hmm good point
[23:33] <Laurenceb> I havent looked around here yet
[23:33] <gordonjcp> you may need to buy a 100m roll, but it won't be very expensive and it's not like you won't use it
[23:33] <gordonjcp> 100m of RG58 was about 40 quid
[23:33] <Laurenceb> hmmm
[23:34] <jcoxon> night all
[23:34] <Laurenceb> I wont need 100m
