[09:51] <Buli> hello
[09:53] <Buli> What is the frequency transmitter habe1 baloon ?
[09:55] <Buli> and altitude 77 meters is final heigh ?
[09:56] <Buli> is anyone here?
[09:58] <fsphil> I think most people are in bed or out atm :)
[09:58] <fsphil> I don't think habe1 is in the air, it's probably just test data. You're seeing it on the tracker yea?
[10:00] <jonsowman> oh whoops I was meant to do an XML for G4TNX wasn't I
[10:00] <jonsowman> better do that
[10:01] <Buli> yes I see it on the tracker
[10:05] <jonsowman> Buli: it's just test data
[10:06] <Buli> ok
[10:12] <eroomde> jonsowman: maplin beehive have this in stock: http://www.maplin.co.uk/700w-x-power-atx-sli-psu-97107
[10:13] <eroomde> seems to fit the bill
[10:13] <jonsowman> can't say I've heard of x-power
[10:13] <jonsowman> but yes, that seems fine
[10:13] <jonsowman> does your motherboard have the additional 2x2 or 2x4 power sockets?
[10:14] <eroomde> no
[10:14] <eroomde> just the 24 pin and the 12v cpu 8-pin job
[10:14] <jonsowman> cool, and the graphics card has 1 or 2 2x3 power sockets?
[10:14] <eroomde> 2
[10:15] <jonsowman> that PSU seems fine then
[10:15] <eroomde> yep
[10:15] <jonsowman> those things are the usual sticking points
[10:15] <eroomde> seems to exactly match the last one
[10:15] <eroomde> might not have pretty sheathed cable bundles but then the fractal itself takes care of hiding ugly cables
[10:15] <jonsowman> very well in fact
[10:15] <eroomde> cool
[10:15] <eroomde> well, worth a try
[10:16] <jonsowman> 700W is more than enough

[10:17] <jonsowman> that's a weird SMA connector
[10:17] <jonsowman> doesn't allow a very thick RF trace between its ground pins
[10:17] <Darkside> i just have large pads on it
[10:18] <Darkside> i could just shrink the page, but tbh the RF trace won't matter so much at that short a distance

[12:22] <m1x10> I don't understand something with the geiger muller tubes
[12:23] <m1x10> they have to work at extremely high voltages
[12:23] <m1x10> how can we fly a tube like this when we run only on 5v or 3v3/
[12:23] <m1x10> ?
[12:25] <BrainDamage> there are circuits that can increase voltage
[12:26] <BrainDamage> what is conserved is power
[12:26] <BrainDamage> so increasing voltage means that you'll be limited in max current you can provide
[12:26] <BrainDamage> which is fine for stuff like geiger tubes which got really tiny consumption
[12:28] <m1x10> but we have few batteries on the payloads

[14:24] <Futurity> hi
[14:30] <Futurity> while i wait for my NTX2 and gps module, i thought i'd get cracking by generating the audio tones and feeding from the Arduino Uno and feed these tones straight into dl-fldigi
[14:31] <Futurity> i take it that the protocol simply changes between these two tones, or is there a silent state and a combined state as well?
[14:32] AndChat| (~nigel@89.192.109.165) joined #highaltitude.
[14:33] <fsphil> normally there are no tones from the avr - just two voltage levels, which causes the ntx2 to generate two frequencies
[14:33] <fsphil> the receiver in USB mode shifts these down into the audio range, making the tones

[14:36] <Futurity> sorry should have said that i'm using the two output pins to control two 555 oscillators
[14:37] <Futurity> with a filter to try and make them approx sinewaves
[14:37] <fsphil> aaah nifty trick
[14:37] NigelMoby (~nigel@cpc5-cdif13-2-0-cust232.5-1.cable.virginmedia.com) joined #highaltitude.
[14:37] <Futurity> i was wondering if the two output pins are ever both high at the same time, or simply alternate with only one being high at once?
[14:37] <fsphil> in that case yes, just two states
[14:37] <fsphil> nope
[14:38] <fsphil> one or the other
[14:38] <Futurity> fantasic :)
[14:38] <Futurity> i'm also trying to get dl-fldigi working on my MAC (had it working on PC before)
[14:38] <Futurity> is it not as simple as just double clicking on the binary?
[14:39] <fsphil> that I can't say, I've not used it on a mac
[14:39] <Futurity> no problem

[15:05] <Futurity> i doesn't matter which one i click on, it tries to open it, but then nothing happens
[15:05] <jcoxon> Then run the applescript binary
[15:05] <Futurity> for some reason if I open terminal, and type the names, they aren't found
[15:06] <Futurity> ok they are in the application folder
[15:06] <Futurity> the icons when in the applications folder has a no entry sign in white over the icon
[15:06] <Futurity> all other icons for working apps work

[15:24] <jonsowman> fsphil: do you mean semicolon?
[15:24] <fsphil> bla:bla:bla
[15:25] <fsphil> bla;bla;bla would work too though :)
[15:26] <ejcweb> So I should have something like $$NEXUS,39,16:22:59,0.000000,0.000000,0,mycustomdata;more;more*202F ?
[15:27] <MNSP> ah are we talking about telemetry string?

[15:27] <MNSP> good oh :)
[15:27] <fsphil> indeedy
[15:28] <MNSP> kinda got mine working

[15:28] <ejcweb> And if I only have one bit of custom data, I don't have to worry about semicolons at all I presume.
[15:28] <MNSP> but checksum seems wrong
[15:29] <MNSP> I think it should be 0728 not 2190 :(
[15:29] <hibby> hola
[15:29] <MNSP> hiya hibby :)
[15:30] <fsphil> ejcweb, yea
[15:31] <Darkside> fsphil: http://rfhead.net/data/MiniHorus_3D_Flip.jpg
[15:31] <Darkside> latest update :D
[15:33] <fsphil> sweet
[15:34] <fsphil> that's gonna be tiny - and fun to solder :)
[15:34] <Darkside> yeah...
[15:34] <Darkside> will be very light tho
[15:34] <fsphil> I bet you could squeeze a few components under the ntx2
[15:34] <Darkside> it might just scrape in under the 50g limit :P
[15:34] <Darkside> i wouldn't want to thought
[15:34] <Darkside> though*
[15:35] <MNSP> Question: How do I get fldigi to show my lat, lonf etc in the little boxes at top?

[15:36] <jonsowman> Darkside: really I would suggest making the rf trace both thicker, and without corners
[15:36] <fsphil> MNSP, do you have a payload xml file setup on the server?
[15:36] <Darkside> jonsowman: yeah
[15:36] <Darkside> thats on my todo list
[15:36] <jonsowman> make it curvy :)
[15:36] <MNSP> no fsphil
[15:37] <fsphil> MNSP, you'll have to fill in the fields manually in the payload conf bit
[15:37] <MNSP> right, I'll go look now, thanks :)
[15:39] <Darkside> jonsowman: how thick should the track be?

[15:45] <Futurity> i think i may have asked this a few months ago, but is it possible to hear the received signal within dl-fldigi?
[15:46] <jonsowman> Futurity: on a mac?
[15:46] <Futurity> on a pc
[15:46] <Futurity> can't get mac version working today so have reverted back to the dark side
[15:46] <jonsowman> yes, you need to use the mixer settings/volume control
[15:46] <MNSP> I do that with the microphone setting, depenmds which os
[15:46] <Futurity> thats an idea
[15:47] <Futurity> do it in the audio prefencies
[15:47] <MNSP> lol, jonsowman beat me
[15:47] <jonsowman> Futurity: dl-fldigi itself can't do it
[15:48] <eroomde> Futurity: no idea on windows but on mac there's a program called LineIn that'll handle that for you
[15:48] <Futurity> jonsowman: thanks that works :)
[15:49] <Futurity> a 1kHz constant tone isn't pleasant after a while
[15:50] <MNSP> sorry to sound dim, but where am I supposed to look for the paylod fields to configure?
[15:50] <MNSP> for the tracker I mean
[15:52] <fsphil> MNSP, DL Client -> Configure -> DL Client -> Payload
[15:53] <fsphil> it won't save it, so if you reload it'll be empty again. to have it setup automatically you need an xml file setup on the server. jonsowman's your man there
[15:53] <MNSP> D'oh and there was me looking on the tracker site as you mentioned servers
[15:54] <MNSP> thanks fsphil
[15:54] <fsphil> wouldn't be massively difficult to setup some kind of xml editor online
[15:55] <jonsowman> fsphil: feel free ;)
[15:55] <MNSP> damn, my fldigi wont start now

[15:59] <jonsowman> http://robertharrison.org/listen/apex.xml
[16:00] <jonsowman> replace apex with any other payload name from dl-fldigi to get others :)
[16:01] <fsphil> could put a time-to-live on them too, so the old ones are cleared automatically
[16:01] <jonsowman> could do. that would require a cronjob or something, and I don't have root access to the server

[17:42] <cuddykid> would a motorola v220 (very very cheap flip phone with usb) be easily hackable? Just found one lying about the house from a few years back? (would use it in future flights)
[17:42] <MNSP> only the fields after the checksum are showing in the little boxes on the top, any ideas?
[17:43] <cuddykid> hmm, the checksum should go at the end of the string?
[17:43] <MNSP> yep and it is
[17:43] <cuddykid> so like: $$habe1,1624,blah,blah,blah,56*A2
[17:43] <MNSP> yeah
[17:44] <cuddykid> so which are the fields after the checksum?
[17:44] <MNSP> bearing and distance, neither of which I am transmitting
[17:45] <jcoxon> MNSP, they are calculated
[17:45] <cuddykid> oh right, hmm, I'm not too sure
[17:45] <fsphil> [OT but cool} http://www.youtube.com/watch?v=-bvmEYxEYiA
[17:45] <MNSP> ah ok, thanks jcoxon
[17:45] <MNSP> but why would the other fields not show up? Or do thety just not show?
[17:46] <jcoxon> well the system needs to know what your fields you are transmitting
[17:46] <jcoxon> this info is taken off the xml file on the server
[17:46] <jcoxon> if there isn't an xml file then it just uses 0 probably
[17:47] <Dan-K2VOL> fsphil holy crap that's a lot of power
[17:47] <cuddykid> fsphil, thats cool
[17:47] <MNSP> ah, right, that makes sense
[17:47] <Dan-K2VOL> sounds like a good balloon experiment, anyone want to go trigger lightning with a balooon?
[17:47] <fsphil> oooooh
[17:47] <cuddykid> lol
[17:47] <fsphil> we don't get enough here lol
[17:47] <fsphil> 28-days notice + thunderstorm just ain't gonna happen :)

[17:48] <MNSP> Jeez, did you see that flash at about 1.02
[17:48] <cuddykid> imagine David Miller responding at that rate... we can only dream..
[17:48] <jcoxon> fsphil, you need to talk to eroomde
[17:48] <jcoxon> stormHAB has been discussed
[17:49] <fsphil> aah yes I remember him talking about that
[17:49] <Dan-K2VOL> huh
[17:49] <cuddykid> oh wow, that sounds good!
[17:49] <jcoxon> we were thinking an upside down dorothy
[17:49] <fsphil> lots of little payloads?
[17:49] <russss> I wonder where you get a 9000fps camera.
[17:49] <jcoxon> fsphil, uhuh
[17:49] <russss> it has pretty good exposure too
[17:50] <MNSP> the chdk boys have a few scripts for capturing single images of lightning
[17:52] <fsphil> there'd probably be enough lift in a thunderstorm to use a smaller than normal balloon
[17:52] <Dan-K2VOL> or a kite ;-)
[17:53] <Dan-K2VOL> heck you could probably get a parachute up to 40,000 ft if you got it into the updraft of a cumulonimbus
[17:54] <cuddykid> I guess W0OTM sees a fair few huge storms!
[17:55] <MNSP> LOL, I am soooo slow today, I only just got what you meant fsphil about the 28 days notice
[17:55] <fsphil> hah
[17:56] <fsphil> We had a nice storm today, why I've been watching all the vids. No ground strikes, but plenty of flashes and noise
[17:56] <MNSP> looks like we may get them here soon, clouds have darkened a lot
[17:57] <MNSP> was nice and sunny up til about 45 mins ago

[18:46] <Randomskk> if this is your new computer you really should be able to
[18:46] <jonsowman> oh that's true

[18:46] <eroomde> i have no windows and a grub-less linux

[18:47] <Randomskk> eroomde: a quick google suggests that os x's diskutil can do it
[18:47] <Randomskk> and dd
[18:47] <Randomskk> I'm not entirely convinced
[18:48] <eroomde> jonsowman: dvd
[18:48] <jonsowman> eroomde: will it boot as a live cd?
[18:48] <eroomde> but that has since died (my dvd writer)
[18:48] <Randomskk> or net boot?
[18:48] <eroomde> yes, but without faffing with mounting random partitions i can't first download the image to use to make the live usb
[18:49] <eroomde> i consider this option more faff than the alternatives
[18:49] <Randomskk> fair enough
[18:49] <Randomskk> did the new psu work out? I saw briefly that nothing happened when you pressed power
[18:49] <jonsowman> i mean, will the mint install disc itself boot?
[18:49] <eroomde> yes
[18:50] <jonsowman> well that's something
[18:50] <eroomde> i could just re-install, but when i apt upgrade i'll have the same problem with grub
[18:50] <eroomde> i will figure something out
[18:51] <jonsowman> well if either the maverick install dvd, or the natty alternative install iso are of any use, you're welcome to them
[18:51] <jonsowman> or if you just want to use my dvd writer

[19:15] <GW8RAK> Hi again NigeyS. Sorry about that. sometimes this keyboard locks up and I have to reboot
[19:15] <NigeyS> eek, give it a good slap, won't help but it'd make you feel better ;)
[19:15] <GW8RAK> Got out for a walk and did a bit of SOTA'ing. Seemed to be a pile up on many channels coming from the Lake District. Very busy.
[19:16] <fsphil> heard a few pile ups today
[19:16] <fsphil> is there a contest going on?
[19:16] <NigeyS> eek @ pileups
[19:17] <LazyLeopard> Pile-ups where? It's been pretty quiet here.
[19:17] <GW8RAK> Was only able to play radio on 2m FM.

[19:17] <NigeyS> 40m was manic earlier
[19:18] <LazyLeopard> Oh. Somehow missed all that. Havn't exactly been scouring the airwaves, though.
[19:19] <GW8RAK> Before saying anything, are we able to post items for sale on here?
[19:19] <GW8RAK> Offer it to the group first before the wider world?
[19:19] <LazyLeopard> Haul for today (and for the week) was one contact on 40 and one on 20.
[19:22] <fsphil> doesn't happen very often GW8RAK, don't think it would be a problem

[21:44] <SpeedEvil> Has aytone played with GPS with just a dipole?
[21:44] <SpeedEvil> How much worse is a dipole, than a helix?
[21:46] <Lunar_Lander> good question
[21:46] <Lunar_Lander> for sure it will be worse
[21:47] <Lunar_Lander> but that is only qualitative
[21:47] <Lunar_Lander> I don't know a quantitative answer
[21:48] <hibby> what the helix has that the dipole doesn't is circular polarization
[21:48] <hibby> given that on GPS satellites the antennas are circularly polarized also, you'll likely get a better signal via a helix because of that
[21:49] <hibby> not to say you can't experiment
[21:50] <griffonbot> @nearsys: Recovered flight #91. Landed in a tree, had limb cut down. Module opened on descent, lost contents. #ARHAB [http://twitter.com/nearsys/status/67345742599168000]
[21:54] <SpeedEvil> Worse - yeah - but it's about an order of magnitude easier to make. :)
[21:56] <hibby> worst case scenario, you get to make your own quadrifiliar helix
[21:57] <SpeedEvil> Naah.
[21:57] <SpeedEvil> Worst case, I wander into the spare room, and pull one off a radiosonde.
[21:58] <hibby> hahah
[21:58] <Lunar_Lander> hi hibby SpeedEvil jcoxon
[21:58] <SpeedEvil> My name is SpeedEvil, and I am an ebay addict.
[21:59] <Lunar_Lander> SpeedEvil I was told that you can't take the RS-80 antenna
[21:59] <SpeedEvil> ?
[21:59] <Lunar_Lander> someone said it isn't possible for some reason
[21:59] <MNSP> lol, sorry was just buyin stuff off ebay
[21:59] <MNSP> otherwise I'd pay more attention ;)
[21:59] <SpeedEvil> It's got a nice amp, I was going to just use that too.
