[00:00] <wb8elk> what voltage are you running Leo?
[00:00] <LeoBodnar_> Cool! I guess it is enough if just one person is connected via globaltuners? Otherwise it is essentially the same signal being distributed?
[00:00] <chrisg7ogx> tks wb8elk
[00:00] <wb8elk> multiple people can tune in via Globaltuners.
[00:00] <LeoBodnar_> Vdd is 2.0V that's the minimum PIC will work at
[00:01] <wb8elk> There are also WebSDR radios..there are several of those out there but not many can tune 434 MHz.

[00:02] <ike> this is 434 radio http://87.248.27.155:8901/
[00:02] <ike> but is soooo sooo far away
[00:04] <LeoBodnar_> wb8elk: I will have a good look at your website tomorrow morning. Are you Bill Brown?
[00:06] <wb8elk> Yes indeed
[00:06] <wb8elk> Leo....I hear it again...it just sent 6 continuous DominoEX transmissions in a row

[00:07] <LeoBodnar_> This is a flight log sampled at 2 hour intervals
[00:07] <wb8elk> I'm afraid I haven't kept my website up to date with the latest payloads...I may have to do that on our holiday tomorrow
[00:07] <ike> LeoBodnar_ type: 434500.00 in frequency abr
[00:07] <ike> bar
[00:07] <wb8elk> It was too weak to copy completely but I did get a lot of partials of that flight log
[00:08] <ike> not callsign
[00:08] <ike> frequency
[00:08] <ike> only noise
[00:08] <ike> and some hum
[00:09] <chrisg7ogx> got B11
[00:09] <ike> This is a WebSDR receiver, located in Skarnes, Norway.
[00:09] <ike> tooo far away
[00:09] <wb8elk> ike...Norway would be way too far away
[00:09] <ike> :)
[00:09] <LeoBodnar_> Cheers ike, how did you find it?
[00:10] <wb8elk> I'm on the Rouen France globaltuners radio
[00:10] <ike> maybe I can get some EME bounce ;)
[00:10] <ike> chrisg7ogx: where are you?
[00:10] <wb8elk> he'd probably have to change the output power from 10 milliwatts to 10 megawatts
[00:11] <ike> LeoBodnar_: Cheers ike, how did you find it? - http://www.websdr.org/
[00:11] <chrisg7ogx> south coast of england NOT Norway!!
[00:11] <LeoBodnar_> wb8elk: here are my humble efforts. B-11 is essentially B-10 relaunched with repaired solar panels and new balloon.
[00:11] <LeoBodnar_> wb8elk: http://leobodnar.com/balloons/
[00:11] <LeoBodnar_> lol chrisg7ogx
[00:11] <wb8elk> Nice Leo....I have some 36" foil balloons that I'm planning to fly soon....very nice super lightweight construction Leo
[00:12] <chrisg7ogx> have to zzz now will leave equipment on o/n GL Leobodnar and tks for excitement
[00:12] <wb8elk> What processor are you using?
[00:13] <ike> It looks like space satelite
[00:13] <LeoBodnar_> It's PIC24FJ
[00:14] <ike> 80MHz no wait states
[00:14] <LeoBodnar_> No, it's not ARM, 16MIPS, 16bit
[00:14] <ike> .... you can bitbang 27MHz
[00:15] <LeoBodnar_> But I write everything in assembly
[00:15] <ike> ARMs have waitstates above 30MHz
[00:15] <ike> or was it 20MHz

[07:26] <ike> what happend to B11?
[07:26] <ike> is it still in the air?
[07:29] <UpuWork> not sure
[07:30] <UpuWork> no RX since early this morning
[07:31] <UpuWork> maybe the French stations may pick it up this morning
[07:33] <ike> F1JSU and F5CT ?

[07:35] <LeoBodnar> Bonjour!
[07:36] <ike> hi leo
[07:36] <ike> so I was thinking
[07:37] <ike> you had a plenty of battery left
[07:37] <keydash> can I attach the communal rooftop antenna to my dongle to receive sdr?
[07:37] <ike> can't your payload malfunction - lets say once every 30 minutes
[07:37] <ike> spitting at 20dbm ;)
[07:38] <keydash> ?
[07:39] <ike> or even drifft somehow to 429.976 - 432.024 MHz so it can be picked buy webSDR at Turin Italy
[07:39] <ike> keydash you can attach everything to your dongle
[07:40] <ike> but to get best results, you need yagi, balun, SDR dongle, long USB cabble, your computer
[07:42] <LeoBodnar> Well I guess unintended malfunction is possible
[07:43] <LeoBodnar> But it's a very shaky ground. I am working on getting a full UK license then it becomes legal to transmit on ham bands over most EU countries.
[07:43] <LeoBodnar> Does Italy allow HAM operation from aircrafdt or balloon?
[07:43] <ike> I have no idea
[07:47] <UpuWork> err
[07:47] <UpuWork> hang on
[07:48] <UpuWork> http://ukhas.org.uk/general:aprs_legislation?s[]=aprs
[07:48] <UpuWork> unknown
[07:48] <UpuWork> http://alerte-radiosondes.blogspot.co.uk/
[07:49] <LeoBodnar> I am planning to have a better look at local legislations later this year. APRS.fi is a good start as you can see whether people installed APRS equipment on their arcraft

[07:52] <LeoBodnar> ike increasing the power seems to help very little because as you lose direct line of sight signal drops very very quickly.
[07:52] charolastra (~quassel@178-190-195-146.adsl.highway.telekom.at) left irc: Ping timeout: 246 seconds

[08:00] <ike> good 434.500MHz yagi antenna
[08:00] <keydash> no :D
[08:00] <ike> you have SDR dongle, right?
[08:00] <ike> do you have laptop?
[08:00] <keydash> not yet
[08:00] <keydash> I bought it last friday
[08:00] <keydash> yeah I have a laptop
[08:01] <keydash> and when i got it i'll track all i can
[08:01] <ike> my dongle is on route too
[08:01] <ike> I ebay it 10 days ago
[08:01] <keydash> with the communal antena can I track those things?
[08:01] <keydash> mine in ebay too
[08:02] <LazyLeopard> Even without the glitches B-11s altitude profile is quite interesting...

[08:47] <Lunar_LanderU> yea

[08:47] <Lunar_LanderU> the HIH-4030 I used before was analogue
[08:48] <Lunar_LanderU> and that oscillated like nothing
[08:48] <Lunar_LanderU> and we couldn't find out why
[08:48] <Lunar_LanderU> one reason might be that standard arduinos have no decoupling on the ADC power supply
[08:48] <LeoBodnar> Does tropospheric ducting happen on 70cm or is it only 2m thing?
[08:48] <Geoff-G8DHE-M> LeoBodnar, following on thought you had last night about plateau regions at the start of each descent the same palteau

[08:50] <LeoBodnar> There must be some energy accumulation/release happening when transitioning through 0ºC level. Until all ice has melted/thawed temperature stays at around 0C. [Maybe]
[08:51] <Geoff-G8DHE-M> Or maybe only WHEN ice forms on the surface ?
[08:51] <LeoBodnar> mattbrejza: what is your station name on the map?

[08:55] <Geoff-G8DHE-M> LeoBodnar, energy only changes when the Ice forms no matter what temperature, if the balloon hits a cloud and below zero then it forms then laurencb suggested cloud last night thats my bet or high area of humidity.
[08:55] Action: LazyLeopard usually nick-shifts to LazyL_M0LEP while tracking, but forgot last night...
[08:56] <Geoff-G8DHE-M> LeoBodnar, Did you catch the Dan Bowen video about ice forming - no solution ?

[09:04] <Geoff-G8DHE-M> but if the air is supersaturated then it wuld plateau when the ice formed rather than at zero ?
[09:05] <LeoBodnar> It looks like 5000m is a sort of an equilibrium level it wanted to stay at. Coincidentally temperature at 5000m was close to 0C

[09:25] <ike> mfa298 can't R pi decode and post data? what about beagle bone black $45+$10 for srd
[09:26] <gonzo__> does it need to decode, or just be a remote sdr

[10:29] <Babs> "Big Ben again kids"
[10:30] <HixWork> He hasn't factored in actual travel times over here though
[10:30] <mattbrejza> 'The Tokyo Electric Power Company (Tepco) had originally said the radiation emitted by the leaking water was around 100 millisieverts an hour.
[10:30] <mattbrejza> However, the company said the equipment used to make that recording could only read measurements of up to 100 millisieverts.'
[10:30] <HixWork> i.e my house to McLaren ~50 miles ~2.5hours
[10:30] <mattbrejza> also 'The new recording, using a more sensitive device, showed a level of 1,800 millisieverts an hour.' more sensitive?
[10:31] <mattbrejza> HixWork: isnt arko used to driving in LA?
[10:31] <Babs> Do you often drive to McLaren?
[10:31] <mattbrejza> which is one massive traffic jam?
[10:31] <mfa298> HixWork: that sounds like a good speed, you're averaging over 10mph

[10:34] <mfa298> sounds a bit like driving around southampton at times

[10:35] <HixWork> I've not been to LA so can't comment on the traffic there - Brussel however is one big jam
[10:35] <HixWork> *Brussels
[10:35] <mfa298> I've heard it said we have the highest ratio of trafficlights per person in europe, and they're all linked together
[10:35] <mfa298> so they can cause you the biggest delay possible
[10:35] <HixWork> linked - nothing is linked in this damnned infrastructure
[10:36] <mfa298> mattbrejza: I think I managed to miss most of the works at redbridge.
[10:36] <HixWork> where are you based mfa298 ?
[10:36] <mattbrejza> if you actualy know soton youll know is quicker to go down the avenue
[10:36] <Babs> Fastest I've ever done is 25 mph for 10km through central London once (well, the Embankment)
[10:36] <mattbrejza> but not if everyone does :P

[10:37] <mattbrejza> everyone going onto the motorway after football can be lolsome (for those going in the opposite direction)

[10:37] <HixWork> "that protesting dude who is now dead" heh
[10:38] <mfa298> redbridge southampton is one of the main motorway routes into southampton and they recently did a lot of work around there, causing chaos.
[10:38] <mattbrejza> it was bad enough without the works

[11:56] <UpuWork> you can solder that

[12:06] <ibanezmatt13> oh good. I'll solder it up then :)
[12:06] <LeoBodnar> If you are measuring altitude then yes

[13:11] <mattbrejza> er
[13:11] <Geoff-G8DHE-M> What populated for you do you mean ?
[13:12] <Lunar_LanderU> no, why I can't do the through-hole version
[13:12] <mattbrejza> well theres no thru hole gps for a start

[13:14] <Lunar_LanderU> yea

[13:15] <Lunar_LanderU> it was suggested to me
[13:15] <Lunar_LanderU> brb
[13:17] <Lunar_LanderU> back
[13:19] <mattbrejza> it probably wont take that long to convert to smd
[13:19] <mattbrejza> the circuit is the same after all
[13:19] <mattbrejza> placement probably wont change that much
[13:20] <mattbrejza> also you can put stuff like the sd card and gps directly onto the board

[13:50] <Lunar_LanderU> UpuWork: in the ava library, which is the chip antenna, is it the JTI?
[13:51] <UpuWork> yes it is Lunar
[13:51] <Lunar_LanderU> ok
[13:52] <fsphil> was there a long-term prediction for B-11 done?
[13:53] <x-f> there was one in the launch announcement - http://ready.arl.noaa.gov/hypubout/15224_trj001.gif
[13:54] <Lunar_LanderU> and how is it connected?
[13:54] <Lunar_LanderU> the one end to the ublox and the other one?
[13:54] <Lunar_LanderU> just ground?
[13:55] <mattbrejza> nc
[13:55] <Lunar_LanderU> ok
[13:57] <fsphil> ah, it's coming back around
[13:57] <fsphil> anyone listening out?
[13:58] <Lunar_LanderU> just being hopeful now
[13:58] <Lunar_LanderU> maybe the board is done by 2015 or so
[13:59] <Lunar_LanderU> (pessimistic, I know)
[14:01] <mattbrejza> fsphil: ill hear it if it comes back
[14:01] <x-f> looks like HASP might launch today (a 11M cu. ft. ZP balloon), they are on the "launch pad" - http://laspace.lsu.edu/hasp/video.php
[14:01] <mattbrejza> but not until tomorrow it seems
[14:02] <WillTablet> The library had a copy of Spivak's Calculus in storage. I couldn't let it go unread.
[14:03] <WillTablet> Man it's gonna be really embarrassing picking up a calculus book from the library.
[14:03] <Lunar_LanderU> two more questions: which grid size for SMD? which track size for SMD?
[14:03] <mattbrejza> why? its not as if there will be anyone else in there to see you
[14:03] <Lunar_LanderU> is 0.254 mm good?
[14:03] <mattbrejza> Lunar_LanderU: you can go finer
[14:04] <mattbrejza> i use multiples of 5mil, whatever that is in mm
[14:04] <mattbrejza> but doesnt matter so much
[14:04] <Lunar_LanderU> OK
[14:04] <Lunar_LanderU> when I get hackvana right, the smallest tracks he can do in normal mode is 6 mil
[14:04] <Lunar_LanderU> so 10 mil probably?
[14:05] <mattbrejza> i tend to do 10 mil and drop down for a few places where i need to
[14:05] <Lunar_LanderU> yea
[14:05] <Lunar_LanderU> 10 mil = 0.254 mm
[14:05] <Lunar_LanderU> ;)
[14:06] <mattbrejza> i find it easier to work in mil
[14:06] <mattbrejza> after all 10mil is a nice number
[14:06] <mattbrejza> 0.254mm is eww
[14:06] <Lunar_LanderU> zea
[14:07] <mattbrejza> after all, the numbers are a bit meaningless outside your board
[14:07] <Lunar_LanderU> yeah
[14:07] <Lunar_LanderU> still hurts my heart somewhat to leave my design
[14:07] <Lunar_LanderU> but well
[14:07] <Lunar_LanderU> probably for the better
[14:07] <mattbrejza> well i assume youre starting from the same schematic?
[14:08] <mattbrejza> eagle can swtich out parts rather than having to start from scratch
[14:08] <mattbrejza> oh youre not eagle
[14:08] <mattbrejza> but i think that program is easier anyyway

[14:58] <ibanezmatt13> and*
[14:58] <chrisstubbs> Yeah you really want a fine tip
[14:58] <ibanezmatt13> chisel?
[14:58] <ibanezmatt13> or the fine needle like ones?
[14:59] <Geoff-G8DHE> I prefer the needle ones
[14:59] <ibanezmatt13> see I have a fine needle tip one but the problem is, the solder doesn't stick onto it easily
[14:59] <ibanezmatt13> So I generally use the chisel
[14:59] <chrisstubbs> ibanezmatt13, is it leaded solder?
[14:59] <ibanezmatt13> yep
[14:59] <chrisstubbs> good
[15:00] <chrisstubbs> might just be monkey metal tip
[15:00] <chrisstubbs> shitanium
[15:00] <ibanezmatt13> no it's a good tip, I just find it tricky to use
[15:00] <x-f> not that's a stable flight
[15:00] <Geoff-G8DHE> iT IS TEMP CONTROLLED ?
[15:00] <x-f> now*
[15:00] <ibanezmatt13> not temp controlled

[15:00] <ibanezmatt13> basic maplin crappy plug in piece of crap
[15:01] <ibanezmatt13> as is the chisel
[15:01] <Geoff-G8DHE> Its probably getting to hot in that case hence the blobby affects
[15:01] <ibanezmatt13> Though I think Im going to invest in some good soldering kit
[15:01] <ibanezmatt13> Can anyone recomend some sort of soldering kit. Temp controlled, nice interface kind of thing?

[15:02] <chrisstubbs> http://www.pcb-soldering.co.uk/ is where i got my kit from, reccomended by hix
[15:02] <ibanezmatt13> thanks, I'LL take a look
[15:03] <Babs> Geoff-G8DHE - i had the same blobby thing with my temperature controlled station. the guide said ramp it up to 450 degrees, i thought it was too hot but the solder blobbing could be solved by taking the temp down.

[15:22] <ibanezmatt13> Geoff-G8DHE: Yea I looked at some videos, they look really handy
[15:22] <UpuWork> nah there is one on dx.com that is meant to be very good
[15:22] <UpuWork> just trying to remember the name
[15:23] <UpuWork> http://dx.com/p/hanko-fx-888-70w-soldering-station-ac-220v-126505
[15:23] <UpuWork> probaly going to have to fit it with a UK plug
[15:23] <UpuWork> but I believe those are good
[15:24] <ibanezmatt13> maybe worth a try
[15:24] <Geoff-G8DHE> Hehe "1 x Chinese user manual"
[15:24] <UpuWork> £71 delivered
[15:24] <ibanezmatt13> I'll look into it
[15:25] <HixWork> I'm not sure Pistorious is allowd to run at all at the moment :)
[15:25] <Willdude123> Man I really need to brush up on my VOR to VOR flying
[15:26] <eroomde> slow down
[15:26] <eroomde> that is described as hanko
[15:26] <eroomde> description claims to be hakko
[15:26] <eroomde> be careful
[15:27] <ibanezmatt13> I'll search for the same thing elsewhere
[15:27] <ibanezmatt13> I'd rather pay a bit more knowing it's the genuine thing
[15:27] <Willdude123> ILS, IFR and VOR seem complicated.
[15:27] <eroomde> we've all been recommending the hakko 888 already upu. just am inclined to be wary with risking money on Tools
[15:27] <eroomde> Tools are important
[15:27] <UpuWork> yup
[15:27] <ibanezmatt13> Willdude123: Take your time, all of it is super easy
[15:27] <eroomde> either you buy it knowing it's a fixie uppie or you buy it knowing you can send it back, is my rule
[15:27] <Willdude123> This is odd, my internet's down.
[15:27] <Willdude123> But I'm still talking to you.
[15:27] <UpuWork> That is very cheap for a nice iron
[15:28] <ibanezmatt13> brb, brother's ball gone over the fence
[15:28] <chrisstubbs> the video for that usb iron is so bad

[15:29] Action: chrisstubbs closes page
[15:29] <eroomde> yeah
[15:29] <eroomde> and why i'm trying to build a lab up slowly with stuff i know is a good investment
[15:29] <eroomde> 2nd hand agilent and marconi and so on
[15:29] <mattbrejza> however when i can go downstairs to use one, ill probably buy sometime later
[15:30] <eroomde> it does make it a slower process that way though
[15:30] <mattbrejza> yae
[15:32] <eroomde> but i have a decent lab at work so am in no hurry
[15:32] <ibanezmatt13> Ok, i'm settled on that Hakko eroomde. Just searching for the best deal on a legitimate product

[15:34] <ibanezmatt13> Generally the pilot will have charts and maps for the area they're flying in which has them all so if they need to fly to one, they have the freqs

[15:37] <Willdude123> Thanks for the support. I think I sound like a plonker anyway.
[15:38] <Willdude123> But it doesn't sound right unless I slightly formalize my voice. And then I end up sounding like a plonker.
[15:38] <Willdude123> Probably because I am.
[15:38] <ibanezmatt13> Willdude123: ALL pilots on ATC sound like plonkers
[15:38] <ibanezmatt13> hence why I've never recorded myself :)
[15:38] <Willdude123> That was just practice :)
[15:39] <ibanezmatt13> eroomde: I'm beginning to think that the Hakko looks a bit basic. True?
[15:39] <Willdude123> I always end up pressing PTT, breathing in, and not saying anything.

[15:40] <Babs> eroomde - its not arko on his way over is it? it would be a good entrance to HALO from HASP when it gets over to Greenwich
[15:40] <ibanezmatt13> and generally you don't need to Willdude123
[15:41] <ibanezmatt13> VFR you generally find yourself looking down at VRPs insetad of VORs

[15:41] <Willdude123> Yeah
[15:41] <eroomde> http://198.120.3.140/Maps/ConvGps643N.htm
[15:41] <eroomde> my friend's project is going up with csbf in december
[15:41] <ibanezmatt13> IFR, you'll find ATC tell you to fly direct to certain VORs and if you're in a decent plane, you don't need to know the FREQs
[15:41] <eroomde> in the antarctic
[15:41] <eroomde> of which i am jealous
[15:42] <HixWork> me too
[15:43] <Babs> I met a photographer once. he had spent 30 years in Africa photographing wildlife, went to Antarctica for a visit and decided he had wasted his life as Antarctica was so much more spectacular

[16:16] <mattbrejza> do you actually want a hot air gun? or are you just drawn to a fancy looking thing?

[16:16] <ibanezmatt13> a bit less ideally
[16:17] <Willdude123> ibanezmatt13, do I need to record the VOR headings too?
[16:18] <Willdude123> Wouldn't that be pointless though, as then it's just a list of headings.
[16:18] <ibanezmatt13> what are you trying to do? ILS?
[16:18] <Willdude123> I'm just trying to fly between VORs. Can autopilot pick up the heading of the vor from the radio?
[16:18] <ibanezmatt13> VORs don;t have a set heading
[16:19] <Willdude123> In the flight plan.
[16:19] <Willdude123> They do.
[16:19] <ibanezmatt13> VOR = very high freq omnidirectional radial
[16:19] <Willdude123> But as in the VORs heading to another one.
[16:19] <ibanezmatt13> well
[16:19] <ibanezmatt13> flying from VOR a to VOR b
[16:19] <Willdude123> There was a tutorial that said tune in to each VOR, and set each one's heading as you go.
[16:19] <ibanezmatt13> yes
[16:19] <Willdude123> But that seems pointless to even tune into it.
[16:20] <ibanezmatt13> If you're flying from one to the other, there will be a bearing you need to fly to get from one to the other, yes
[16:20] <ibanezmatt13> So, using the map, find a bearing
[16:20] <Willdude123> Ah I kinda get it. So what's the point in the vor?
[16:20] <Willdude123> Is it just useful as a waypoint?
[16:20] <ibanezmatt13> otherwise your vor indicator would have no idea where it was
[16:20] <Willdude123> Ah OK
[16:21] <Willdude123> Is it not simpler to use GPS?
[16:21] <ibanezmatt13> probably, but you won't be allowed to do that on your PPL checkride
[16:21] <ibanezmatt13> This is why I'd buy a plane for FSX instead of the crap that comes with it

[17:20] <keydash> i'm wondering
[17:20] <keydash> to test sdr transmission homemade,
[17:20] <keydash> i need
[17:20] <keydash> arduino uno and ntx2?
[17:20] <ike> quick question did you use LDO for si4432? DS say absolute maximum 3.6v and charged battery have 4.2V voltage
[17:21] <ike> keydash what do you want to test TX or RX mode?
[17:21] <keydash> just simulate a ballon emiting telemtry
[17:22] <keydash> what's the difference between rx and tx?
[17:23] <ike> if you have new SDR dongle you wana test RX ;)
[17:23] <ike> if you have new ntx2 then you wana test TX
[17:23] <keydash> I need to learn lot of things, step by step xD
[17:23] <keydash> well
[17:24] <keydash> sdr to the laptop and ntx2 to the ballon, no?
[17:24] <ike> there is websdr station near you 429.976 - 432.024 MHz
[17:25] <tweetBot> @daveake: #RaspberryPi #UKHAS Blog post on the Babbage flights http://t.co/T2ki4eq5Qo
[17:25] <ike> do you have sdr dongle, ntx2 and arduino?
[17:26] <keydash> right now, no
[17:26] <keydash> i'm harvesting ideas
[17:26] <keydash> i've ordered sdr
[17:26] <ike> http://websdr-rtl.radio.it/
[17:26] <keydash> i have a raspberry pi

[17:28] <keydash> hmm
[17:28] <keydash> so
[17:28] <keydash> I'll need to attach one of those modules to arduino
[17:28] <ike> regular arduino is 5v and those modules are 3.3v
[17:29] <ike> https://www.google.com/search?num=100&q=rfm22b+arduino
[17:30] <keydash> >_<
[17:31] <mfa298> ntx2 will be a lot easier to use than the si chips.
[17:31] Penfold (~mike@iannos.altrion.org) left irc: Read error: Connection reset by peer
[17:31] <mfa298> you can also use the ntx2 with a raspberry pi easily - a couple of resistors and connect to the serial port
[17:31] <keydash> but can I recover GPS data from there?
[17:31] <keydash> with the sdr dongle
[17:32] <keydash> raspberry
[17:32] <mfa298> the sdr dongle is just a radio reciever (you could use it to listen to the local radio station, Ham bands, airband, marine band etc)
[17:32] <keydash> so I can receive the data of the ntx2?

[17:33] <fsphil> less to go wrong on an arduino

[17:34] <keydash> and i wouldn't like to lose it
[17:34] <fsphil> though the Pi's can certainly handle the environment

[17:35] <chrisstubbs> keydash, http://ukhas.org.uk/guides:linkingarduinotontx2 is probably what you are after then
[17:35] <mfa298> my only reason for saying you can use the Pi is you said you had one. Python is probably easier to learn and understand if you've not done programming before
[17:35] <keydash> i read that while ago :D

[17:36] <keydash> xD
[17:36] <keydash> mfa298 good
[17:37] <keydash> so you advice me arduino uno + ntx2?
[17:37] <keydash> and the laptop + sdr dongle?
[17:37] <mfa298> if you've got programming experience you might not find the arduino so bad.
[17:38] <mfa298> for a payload arduino is probably the better choice - you can use the uart for gps and as it's real time you can easily bitbang the rtty on a gpio

[17:39] <keydash> and the cheapest? :D
[17:39] <mfa298> if you want a cheaper option you can look at the SI chips (like ike linked to)
[17:39] <keydash> nice
[17:40] <keydash> when i receive the dongle and test it i'll order those things
[17:40] <mfa298> rfm22b has been popular (which I think uses one of the SI chips) but they've also been known to fail in the cold
[17:41] <ike> that is true, because it have better efficiency than ntx2, thus generating less heat
[17:41] <ike> that is not disadvantige
[17:42] <ike> just make sure that you isolate it better
[17:42] <mikestir> has anyone tried the rfm23b airborne? that uses the si4431 instead of 4432, but it could still achieve +10dBm and doesn't have the complexity of the antenna switch (so less to go wrong)
[17:42] <keydash> just want to try RF telemetry firtsly
[17:42] <keydash> once that works
[17:42] <keydash> i'll prepare a flight

[17:45] <mfa298> if you're just taking pictures at altitude people just use a fairly cheap camera from ebay that can run chdk
[17:45] <ike> and you are ready to experiment
[17:46] <mfa298> if you want to send back live images then you may need to use a pi rather than arduino
[17:46] <keydash> wow really cheap
[17:46] <mikestir> those tx modules are definitely not suitable

[17:49] <ike> this is good to maybe 100-500M
[17:49] <keydash> at 500m i'll lost the signal?
[17:49] <mfa298> I'm not sure i'd say those modules are good for any flights
[17:51] <keydash> xD
[17:51] <keydash> I don't want to lost the equipment on the sea, and the sea is near me so, I'll try to do short ranged flights
[17:51] <keydash> but I'd like to get high
[17:52] <mfa298> for seeing where flights would go there's the predictor which should give a good idea

[17:58] daveake (~Dave@daveake.plus.com) joined #highaltitude.
[17:58] <ike> http://aprs.fi/#!lat=41.3588&lng=2.1533
[17:58] <mfa298> depends on where you are and your license, I could use 400W RF power on arps if I wanted (at least on the ground)
[17:59] <keydash> as i see on the map
[17:59] <keydash> there's a association on my country (i'm not form the capital)
[17:59] <keydash> *from
[17:59] <keydash> i'll ask if i reach that phase
[17:59] <ike> just get basic ham license
[17:59] <mfa298> with aprs as it's a shared channel you can also only send data every few minutes otherwise you clog the radio channel
[18:00] <keydash> and near to my home
[18:00] <keydash> but i live on the basement on a flat
[18:00] <keydash> xD
[18:00] <mfa298> with the ukhas method you can send any data you want and several updates a second.
[18:00] <keydash> ukhas method is good for my interest
[18:00] <keydash> real time data i want
[18:01] <keydash> the photos can wait or can be separated from RF
[18:01] <keydash> with a spy camera or something like that
[18:01] <mfa298> the easiest way to get photos from altitude is to just send up a suitable camera with the tracker and get the pictures back after it's landed
[18:02] <Upu> ping LeoBodnar launching again ? Want me to kill B11 ?
[18:02] <keydash> but that doesn't give real time data
[18:02] <keydash> and as i know, 3G and those bands are restricted on altitude
[18:03] <mfa298> just becareful with cheap cameras they've been known to jam gps
[18:03] <DutchMillbt> Good Evening Yáll B12 launching ?
[18:03] <Upu> not sure DutchMillbt
[18:03] <Upu> just ascertaining now
[18:04] <mfa298> what other people have done is send up a arduino payload to give telemetry data and then a seperate camera. If you want live images look at ssdv (on the wiki), but for that it's much easier with a pi

[18:37] <ike> I don't know how this work http://spacenear.us/tracker/
[18:37] <ike> but it wold be nice to have some info
[18:37] <Geoff-G8DHE> It shows the track of a balloon, that is being watched
[18:38] <ike> of time past since last packet
[18:38] <Geoff-G8DHE> Click on Follow on B-12, also "Pan to"
[18:38] <bertrik> the large circle around it is the expected radio range
[18:38] <jcoxon> B11 is a bit messy
[18:38] <Geoff-G8DHE> as that is flying now, still very low so not many trackers yet
[18:38] <mfa298> ike it might be worth reading the ukhas wiki there's a lot of information on there
[18:39] <mattbrejza> will be lolz if b11 comes back to life now
[18:39] <Geoff-G8DHE> to make it simpler Click on the Settings Tab and just enter B-12 then it will only show the single balloon
[18:39] <Geoff-G8DHE> B-12 is 500Hz lower than B-11 just in case!

[18:40] <mattbrejza> indeed, however if anytyhing they should be the same
[18:40] <Geoff-G8DHE> The balloon area shows the latest telemetry eceived
[18:40] <mattbrejza> they tdma anyway
[18:40] <Geoff-G8DHE> indeed
[18:41] <Geoff-G8DHE> but the 3 sec blips might cause problems
[18:41] <mikestir> meh there's a big carrier on 434.5 here
[18:41] <ike> so this is right frequency 434499.50
[18:42] <Geoff-G8DHE> Close enougth watch out for the blip every 3 seconds on B-12 and center that in the passband
[18:42] <mattbrejza> i have two fldigis open just incase b11 comes back
[18:42] <jcoxon> mattbrejza, its been a while since b11 tx'd
[18:43] <mattbrejza> yea but if you look at the prediction its supposed to come back over the uk after 2 days
[18:43] <jcoxon> fair enough
[18:43] <mattbrejza> but going by its ups and downs i guess its crashed by now
[18:45] <LeoBodnar> Yeah, it was a bit unstable
[18:45] <LeoBodnar> B-12 might be even worse
[18:45] <LeoBodnar> We'll see.
[18:46] <eroomde_> B12 is the same hardware?
[18:47] <ike> LeoBodnar did you implement stability "issues"?
[18:48] <mattbrejza> i think b12 is a fixed b10
[18:49] <mattbrejza> fixed/repaired
[18:49] <LeoBodnar> Yes, but lighter payload and more free lift.
[18:49] <mattbrejza> so still solar w/ lipo?
[18:49] <ike> aren't b11 a fixed b10?
[18:49] <LeoBodnar> B-11 was fixed B-10, B-12 has been just built (together with B-13)
[18:49] <mattbrejza> oh right
[18:50] <LeoBodnar> Yes, lighter LiPo though

[18:51] <eroomde_> arriving wed
[18:51] <Upu> sub £300
[18:52] <eroomde_> tbh i don;t have that money for that kinda thing atm
[18:52] <eroomde_> but it's a good price
[18:52] <eroomde_> we have a pair of really really nice marconi siggens
[18:52] <eroomde_> at work
[18:52] <eroomde_> Upu: digital and with storage or analogue?
[18:52] <LeoBodnar> Lovlies. I have Marconi that I have repaired so it is a bit wonky.
[18:53] <Upu> in fairness no idea
[18:53] <LeoBodnar> But works well for occasional jamming crap music in the nearby workshop.

[19:00] <eroomde_> good deal if anyone is in the market for a decent multimeter
[19:04] <LeoBodnar> I can see you've been rediscovering eBay :)
[19:04] <mfa298> looks to be some nice toys that person is selling. Don't think I can justify the money/space though at present
[19:06] <ike> LeoBodnar your balloon is heading to #47 431.982 - 432.078 MHz WebSDR at Dwingeloo, The Netherlands http://www.websdr.org/ so if your transmitter glich somehow maybe it will send 432 MHz data
[19:06] <LeoBodnar> Well it can't :)
[19:06] <mfa298> Leo's payloads are very good at staying legal.
[19:07] <eroomde_> mfa298: yep tempting isn;t it
[19:07] <LeoBodnar> I think we have a few keen trackers in NL
[19:07] <eroomde_> alas no slush fund lying around for toys atm

[19:10] <adamgreig> oh my god buy that iron
[19:10] <eroomde_> metcals*
[19:10] <Upu> very yes
[19:10] <adamgreig> though with 12 days left it will go above 125
[19:10] <chrisstubbs> Yep!
[19:10] <adamgreig> probably out of your budget
[19:10] <Upu> mine is my favourite thing
[19:10] <eroomde_> buy it now
[19:10] <mfa298> especially if you look at that websdr "Currently, there is no live reception. Instead, we're playing a recording made during ... was made on April 17, 2010, around 19:00 UTC, on 70 cm"
[19:10] <adamgreig> oh
[19:10] <adamgreig> so it is
[19:10] <adamgreig> friggin buy it
[19:10] <adamgreig> easily
[19:10] <Upu> make an offer of £100 :)
[19:10] <adamgreig> if you don't buy it I might well
[19:10] <eroomde_> yep
[19:10] <mattbrejza> how does one calibrate a soldering iron :/
[19:11] <eroomde_> he accepted my offer of 2 PSUs @ 100e a when listed for 120

[19:11] <adamgreig> lol
[19:11] <eroomde_> yeah i'm almost tempted!
[19:11] <adamgreig> one day I will read the whole page before making stupid comments like "it will go up in price" or "if you don't buy it I will"
[19:12] <mattbrejza> after all if youre signing off something to a customer, they need to know it was soldered at exactly the right temperature :/
[19:12] <Upu> its ok Metcals have this effect

[19:13] <Steve_2e0vet> ping chrisstubbs
[19:13] <eroomde_> so you want to make sure you have the right (lead vs lead free) tips

[19:13] <chrisstubbs> Hi Steve_2e0vet
[19:13] <ibanezmatt13> I'd go buy it but I know I won't use it that much. I won't be purchasing this thing just now :)
[19:13] <adamgreig> though now I look, onecall has a metcal for £148
[19:13] <ike> mfa298 you are right, it's a recording :(
[19:14] <adamgreig> not as good though
[19:14] <ike> no live stream
[19:14] <mattbrejza> do those tips have the element as part of them?
[19:14] <Steve_2e0vet> hi chrisstubbs to save me looking through your video again, which resistor did you select
[19:14] <eroomde_> you won't regret the hakko anyway ibanezmatt13
[19:14] <eroomde_> it's a splendid iron
[19:14] <chrisstubbs> 10 for the pullup on reset
[19:14] <adamgreig> http://onecall.farnell.com/oki-metcal/sp200-21/soldering-system/dp/SD01489 is what I want
[19:14] <chrisstubbs> *10k

[19:46] <Upu> well
[19:46] <Lunar_Lander> in EAGLE I'd have them, but would have to redo the schematic
[19:46] <Upu> I suspect it would be quicker to redo the schematic
[19:46] <Upu> than redo the parts
[19:46] <Lunar_Lander> yea
[19:46] <Lunar_Lander> also the SMD board hopefully fits the 100x80 mm limit
[19:47] <LeoBodnar> Iain_G4SGX: I tend to think it is ice accumulation in concert with thermal inertia of the gas inside the balloon.

[20:02] <Willdude123> ibanezmatt13, how do people look around the cockpit in youtube vids?
[20:02] <ibanezmatt13> they have a joystick?
[20:02] <ibanezmatt13> with a thing on the top you move to pan around
[20:03] <Lunar_Lander> does anyone have a good SMD 3.3V regulator that has a decent max. current?
[20:03] <Lunar_Lander> the most on farnell only have something around 100 to 200 mA
[20:03] <Lunar_Lander> and the higher currents are only available as 2500 piece tape
[20:04] <Willdude123> Ah right. Is there some way of doing it with the mouse. Oh BTW did my first vor to vor successful flight.
[20:04] <LeoBodnar> What are Vin and current you need?
[20:05] <ibanezmatt13> Willdude123: I'll be honest, I don't know how you can use FSX and like it with a mouse. Get a joystick!
[20:05] <Willdude123> I have one
[20:05] <Maxell> bertrik: holy shizzle I can see it on the waterfall
[20:05] <Willdude123> It just has buttons on the top

[20:06] <LeoBodnar> Maxell: where are you and what is you name on the map?
[20:06] <Maxell> bertrik: 434.500 MHz in SDR# and 1740 Hz in dl-fldigi.
[20:06] <ibanezmatt13> Willdude123: I may be wrong but in the virtual cockpit if you hold ctrl and move the mouse it may pan around
[20:06] <SpeedEvil> Lunar_Lander: there are linrear regulator controllers that you connect a FET or transistor
[20:06] <Maxell> LeoBodnar: The Hague, as RevSpace.
[20:06] <ibanezmatt13> or spacebar or something Willdude123
[20:06] <Willdude123> ibanezmatt13, actually I've just realized I can't really afford a plane
[20:07] <LeoBodnar> Ooh well done!
[20:07] <Lunar_Lander> do you have an example SpeedEvil ?
[20:07] <ibanezmatt13> :)
[20:07] <LeoBodnar> What plane?
[20:07] <Willdude123> A £20 FSX plane
[20:07] <Maxell> Semi-pre-horizon. lolz $9 USD ezcap
[20:07] <LeoBodnar> Ah, I thought real one.
[20:08] <SpeedEvil> not to hand. Digikey has a separate category for them
[20:08] <Willdude123> Suppose I may as well
[20:09] <LeoBodnar> Lunar_Lander: what is Vin and current?
[20:09] <Lunar_Lander> Vin is about 7-8 V
[20:09] <Lunar_Lander> current is about 150 mA

[20:10] <Lunar_Lander> LeoBodnar, thanks
[20:10] <SpeedEvil> sounds right

[20:10] <LeoBodnar> Up to 18V so you can plug a typical "12V" plug-in power supply.
[20:11] <Lunar_Lander> sounds good
[20:11] <LeoBodnar> Well done again Maxell
[20:11] <LeoBodnar> I can see you on the map
[20:12] <Maxell> Thanks LeoBodnar. I think it's one of the first times seeing DomEX16 so clearly.
[20:12] <LeoBodnar> Oh, good, it's coming your way
[20:12] <Willdude123> ibanezmatt13, Just bought it. :/

[22:37] <WillTablet> mfa298 I found my library actually has one decent textbook.
[22:37] <WillTablet> Calculus by Spivak. Got it reserved.

[22:38] <mfa298> I reckon you're probably a bit mad trying to understand calculus at this point but if it's what you want to do go for it.

[22:39] <mfa298> a textbook being decent probably depends on whether it's written in a way that you can understand
[22:40] <mfa298> I've had some "good" textbooks that I've really struggled with
[22:40] <WillTablet> mfa298, I agree.
[22:40] <WillTablet> Well, it's free-
[22:40] <WillTablet> I'll have a read of my 1089 book.

[22:41] <WillTablet> I agree, I'm in set 2 for maths which is a bit crap too
[22:41] <adamgreig> eh
[22:41] <adamgreig> I was in set four out of five (five was the worst) at GCSE
[22:42] <adamgreig> only person in my set to not take foundation GCSE
[22:42] <adamgreig> I wouldn't worry about it too much

[22:42] <adamgreig> (for maths, to clarify)
[22:42] Nick change: KipK -> KipK_away
[22:43] <mfa298> In year 8 I wasn't that good at maths (not in sets), then I think I was in Set 2 at the start of Year 10 (possibly year 9) and moved up to set 1 later on
[22:43] <adamgreig> I never even got moved up :(
[22:43] <adamgreig> showed them in the end
[22:44] <WillTablet> Maths is so stupid, but maths is amazing, if you get what I'm saying.
[22:44] <adamgreig> uh huh
[22:44] <mfa298> I think part of the problem I had was motivation.
[22:44] <mfa298> WillTablet: I think that's probably a good summary of how maths was for me at school.
[22:45] <mfa298> but becareful not to push yourself too far or you could end up going off maths.
[22:45] <WillTablet> I know I probably shouldn't say this since he probably stalks kids on the internet, but it's difficult, having a sadist, low-life maths teacher
[22:45] <mfa298> and if you're interested in science/engineering stuff maths is very important
[22:46] <WillTablet> Who just throws pointless exercises ( and pens) at people
[22:46] Action: chrisstubbs goes on another guilt trip about giving up maths
[22:46] <mfa298> if the exercises help you remember then they're not pointless.
[22:46] <WillTablet> I just thought oculus rift would be so cool with FSX
[22:46] <WillTablet> They don't
[22:47] <mfa298> and the bits of maths I remember most are the bits I did lots of pointless exercises for.
[22:47] <WillTablet> I remember how difficult and pointless they were.
[22:47] <WillTablet> I don't remember what they were about
[22:47] <mfa298> if you're finding the thing in the exercises difficult then you might need more practice at it.

[22:48] <WillTablet> It would be so cool because you could look out the window and stuff
[22:49] <WillTablet> A 737 sim costs the same to go in as a light aircraft lesson does
[22:49] <mfa298> I can still remember eyebrows and chins from doing secondary school maths, I'd have to look at a text book to remember some of the things I did at Uni

[22:50] <LeoBodnar> See you tomorrow
[22:51] <chrisstubbs> nice and strong here now, its right on my doorstep
[22:51] <KJ4AFL> What is the status of B11 has it stppped updatin?
[22:51] <mikestir> lol. I keep getting english words in legitimate addresses in some code I'm debugging
[22:51] <mikestir> the latest one starts 0xbed
[22:51] <adamgreig> haha
[22:51] <mikestir> I think it's trying to tell me something
[22:52] <adamgreig> definitely a sign
[22:52] <mfa298> you need to see if you can change it to 0xc0ffee
[22:53] <ike> what are those http://spacenear.us/tracker/ mod1 and mod2
[22:54] <KJ4AFL> Again, what is the status of B11?

[22:58] <KJ4AFL> That is what I thought was going on. Thanks for the update mfa298.
[22:58] <ike> so I think that is somewhere in the feelds of france
[22:59] <LeoBodnar> KJ4AFL: no signs of B-11 but there was some signal picked up earlier where in theory B-11 should have been (500Hz above B-12) http://i.imgur.com/pepwszY.jpg
[22:59] <LeoBodnar> It's unexplained so far but assumption is that B-11 has landed somewhere

[23:51] <mfa298> the right way to code is to start up from something simple

[23:53] <Bo_DK> LeoBodnar: B-12 ??
[23:54] <mfa298> get started with using a source code managment system (like git)
[23:55] <mfa298> the point isn't a way to share code. The point is that you continually check your code in as you make changes. That way if you find something broke you can quickly revert back to a previous version

[23:57] <Bo_DK> ie a bit of sleep first
[23:57] <mfa298> and as I think you're new to programming start off small, maybe just start getting data from your gps module
