[00:02] <KT5TK> N2NXZ: Nice payload!
[00:02] <KT5TK> Do you transmit WSPR?
[00:03] <kc2pit> I've become totally spoiled by soldering under a stereo microscope.
[00:03] <N2NXZ> No,have not messed with WSPR,a bunch of guys I know are involved with those new QRSS kits
[00:05] <N2NXZ> I just run a 10m beacon at the campsite,it runs on soalr.
[00:05] <N2NXZ> solar
[00:05] bertrik (~quassel@rockbox/developer/bertrik) left irc: Remote host closed the connection
[00:06] <N2NXZ> This AD9850 will prbably be too weak without a PA stage,but too much battery as it is.
[00:06] <KT5TK> So what do you generate with the DDS?
[00:06] <arko> KT5TK: nice flight so far :)
[00:06] <N2NXZ> RTY beacon
[00:06] <N2NXZ> RTTY
[00:06] <arko> was hoping it could come by my place, but i guess not http://ready.arl.noaa.gov/hypubout/117371_trj001.gif
[00:07] <KT5TK> AH OK, I tried PSK on 20m and 40 m on a balloon
[00:07] <KT5TK> Worked great
[00:07] <N2NXZ> I wanted psk31
[00:08] <N2NXZ> It should be fun anyway it goes.All in fun,as long as it leaves the launch pad...
[00:08] <KT5TK> Hi Arko, So far BLT40.1 didn't follow the prediction at all
[00:09] <arko> looks like it may have hit a few storms
[00:09] <KT5TK> Very slow winds (actually none)
[00:09] <arko> got rained on maybe?
[00:09] <arko> yeah
[00:09] <arko> crazy
[00:09] <arko> going to ukhas conf this year?
[00:09] <KT5TK> No, I have to prepare to move back to Germany.
[00:10] <KT5TK> But maybe next year again
[00:10] <arko> aww
[00:10] <arko> cool
[00:10] <arko> i'll be in germany for like 3 days in 3 weeks
[00:10] <arko> excited :)
[00:11] <KT5TK> I'll not be there that soon.
[00:11] <arko> hehe
[00:11] <arko> cool cool
[00:11] <KT5TK> But if you are in Berlin, contact DL7AD
[00:11] <arko> i wont be in Berlin unfortunatly, just Stuttgart :/
[00:11] <KT5TK> He'll come to the conference also
[00:11] <arko> yeah!
[00:12] <arko> but anyway, nice flight
[00:12] <KT5TK> Let's see how long the batteries last
[00:12] <KT5TK> 2 x AAA
[00:12] <arko> whats onboard?
[00:12] <arko> oh
[00:12] <arko> depends how power efficient you are
[00:13] <arko> probably 5-6days or so if you are very conservative
[00:13] <KT5TK> That's what I try to find out.
[00:13] <arko> does it power down the gps & radio?
[00:14] <KT5TK> I switch everything off: GPS, VCXO, tx and the micro itself
[00:14] <arko> oh wow
[00:14] <KT5TK> at a 10 minute cycle
[00:14] <arko> do you have the battery line connected to keep the empheris data?
[00:15] <KT5TK> yes
[00:15] <arko> nice
[00:15] <arko> should be interesting to see what happens
[00:15] <arko> hope you don't hit too many storms
[00:15] <arko> thats what brought down my last floater :/
[00:15] <KT5TK> at this altitude it would be fatal
[00:16] <arko> heh yeah
[00:16] <arko> 5000m is pretty closse to the ground
[00:16] <KT5TK> the two AAA are heavy.
[00:16] <arko> oh yeah
[00:16] <arko> 7-9g each right?
[00:16] <arko> i forget
[00:16] <KT5TK> But I thought that the efficiency of the buck reg was better at 3 V
[00:17] <KT5TK> sorry boost & buck reg
[00:17] <arko> not sure, depends which one you used
[00:18] <KT5TK> TPS61201
[00:20] <arko> are the batteries parallel or series?
[00:20] <KT5TK> series
[00:20] <arko> ah ok
[00:20] <arko> its probably around 90%
[00:21] madist (madist@unaffiliated/madist) joined #highaltitude.
[00:21] <arko> assuming you are buck/boosting the 3V to around 3 to 3.3v
[00:21] <KT5TK> yes, 3.3V out
[00:21] <arko> ah cool
[00:21] <arko> nice
[00:24] <KT5TK> At 1.5 V (which I used before) the efficiency is just at 60%

[01:18] <KT5TK> aadamson: Thanks. Did you notice that I do need WIDE2-1?
[01:19] <aadamson> I didn't even look, let me look
[01:20] <aadamson> you know it's impossible to know whether an Igate heard you because of the dedupping that happens at the IS servers
[01:20] <aadamson> if the wide2-1 relayed you first, then it won, etc
[01:20] <aadamson> only real way to know it go NO-PATH - which I just did
[01:21] <aadamson> worked great until I got 50miles off shore :(
[01:21] <aadamson> but also the infrastructure in the jacksonville, fl area - SUCKS! :)
[01:23] <aadamson> I was being heard by an igate 220mile northeast of me, but nothing south of savannah and the balloon was only 50miles off shore...
[01:23] <aadamson> but bottom line, this Wide1-2 vs. NOPath thing.... I'm kinda disenchanted with the NOPATH thing due to recent experience
[01:24] <KT5TK> agreed.
[01:25] <aadamson> oh, looks like you are taking the path of arko's hysplit
[01:25] <aadamson> making a turn back to the east
[01:25] <KT5TK> For a balloon launch in a metro area no path is fine, but when you get to rural areas you need every digi that you can get
[01:25] <aadamson> btw, how low will the batt go before the smps will stop working
[01:26] <aadamson> yep, I'm pretty much there, just had to prove it to myself and I just did that (and fed the fishes) :)
[01:26] <KT5TK> In my experience about 0.8 V
[01:26] <aadamson> is there a buck and boost?
[01:26] <aadamson> same controller or separate?
[01:26] <KT5TK> Then the GPS freaks out and kills the battery fast
[01:27] <KT5TK> Yes, TPS61201
[01:27] <KT5TK> only one
[01:27] <KT5TK> I managed to get the uBlox to sleep through serial
[01:29] <aadamson> ah, yeh, I was looking at some of that last night actually
[01:29] <aadamson> I use PSM through serial, but noticed that you can also put it in standby
[01:29] <aadamson> and then bring it back with a 0xff on the serial port
[01:29] <KT5TK> Yes, that's how I do it
[01:30] <aadamson> awesome...
[01:32] <KT5TK> Here are all the tricks: http://ukhas.org.uk/guides:ublox_psm
[01:33] <aadamson> ah, excellent reference

[01:35] <aadamson> are you running the Q?

[01:36] <aadamson> thats great... when I do my 3v3 board, I'll use the 7Q
[01:37] <aadamson> I figured out the other day that I can use the exact same design as my 2.0v version just drop in an STM32F303 in place of the STM32L151
[01:37] <aadamson> got from 32mhz to 72/84 and get dsp and hardware floating point - all at the cost of more mA's
[01:38] <KT5TK> Great! that's how it should be
[01:38] <aadamson> but that isn't really a low current platform on the 303
[01:38] <aadamson> I don't even have to change any pins

[01:40] <KT5TK> but still power saving
[01:40] <aadamson> ya spi to the camera or something *fast* :)

[01:46] <KT5TK> That gives me about 5 days which was more than enough so far
[01:46] <aadamson> ah
[01:46] <aadamson> I run a version of PLAN13 that I found online and then I hacked it up
[01:47] <aadamson> it calculates every second, the lat/lon/elevation/rx dop/tx dop of the ISS
[01:47] <KT5TK> I tried that too, but they used too many variables so that the atmega ran out of RAM
[01:47] <aadamson> based upon the current gps position
[01:47] <aadamson> yah, I have 16k, but am only using about 6K
[01:48] <KT5TK> So after a day or two I gave up and just did the pre-calculation
[01:48] <aadamson> hehe
[01:48] <aadamson> Well, so far it's been for not... at 2.0v, the 4463 will only do 35mW at max power anyway
[01:49] <aadamson> and I forget are you on 2 AAA's?
[01:50] <aadamson> probably as AA's are too heavy
[01:50] <KT5TK> Yes at 3.3V I get closer to 60 mW
[01:50] <aadamson> what did you payload weigh?
[01:50] <KT5TK> 2x AAA
[01:50] <KT5TK> 19g
[01:50] <aadamson> you know that's funny... on my original design where I just did it on a pro-mini plug in board
[01:50] <aadamson> I got 100mW consistently
[01:51] <aadamson> I've never checked my current layout (it's your LPF) to see what it would do on 3v3
[01:51] <KT5TK> I wanted to try the 3 V because that's where my power reg is more efficient
[01:52] <KT5TK> 2 x AAA in series
[01:53] <aadamson> ah yeah, that makes sense on my original design it was on a 250ma 3v3 LDO
[01:54] <aadamson> so is germany home?
[01:54] <KT5TK> Yes, Berlin
[01:54] <aadamson> are you moving back home - for the foreseeable future?
[01:54] <aadamson> ah very nice!
[01:54] <aadamson> how long have you been in the US?
[01:54] <KT5TK> Yes, I need to sell my house here in Houston
[01:55] <KT5TK> 8 years
[01:55] <aadamson> ah, single, married?

[08:40] <jcoxon> we don't use it for tracking habs as the transponders are large and heavy
[08:40] <jcoxon> its also a big sky so collision is a very small risk
[08:40] <jcoxon> so you don't need to check before you launch
[08:41] <cipherzero> I know its small but still there
[08:41] <jcoxon> yeah but you'll find that you'll pass through the zone of aircraft very quickly
[08:41] <cipherzero> Yeah, I know
[08:41] <jcoxon> so launch we get permission

[08:41] <jcoxon> so you can't get permission near airports etc
[08:42] <cipherzero> right
[08:42] <jcoxon> there is also the fact of what can you do
[08:42] <jcoxon> the balloon is a free once launched
[08:42] <Maxell> Chetic: flightradars.eu??? Why not just flightradar24.com?
[08:42] <Chetic> youwhatnow
[08:44] <cipherzero> Also a question about methane and hydrogen
[08:45] <gonzo__> they are both fun, what more is there to know?
[08:45] <malgar> the long waiting for the B-6* return
[08:46] <cipherzero> So this is what happened two years ago http://www.smh.com.au/world/balloon-blasts-injure-140-in-armenia-20120505-1y5aj.html
[08:46] <malgar> will they appear over england? :) or over morocco? or will they die?
[08:47] <gonzo__> yes
[08:49] <cipherzero> so uh, if filling a weather balloon with hydrogen, if there's no fire nearby, what can cause the ignition?
[08:50] <gonzo__> h2 and the public are not a great mix. I'll bet that the ignitions was someone trying to pop a balloon with a lighter for fun
[08:51] <cipherzero> I think it was actually methane in that video, dont know why the press said hydrogen
[08:51] <cipherzero> but anyway, not launching in a public place
[08:51] <gonzo__> filling your own balloon, you take the basic precautions. keep people away and don't apply a lighter
[08:52] <gonzo__> is methane that bouyant?
[08:52] <cipherzero> methane is like 4 times less than helium I think but still floats, yeah
[08:52] <gonzo__> we used to launch bin bags filled from the gas stove as kids, but it bearly had any free lift
[08:53] <gonzo__> prob not the lightest bags either
[08:53] <cipherzero> I dont remember if Ive asked this before, can static electricity happen when filling a balloon with hydrogen
[08:53] <gonzo__> (and a bit of burnming bog roll hanging below
[08:53] <Darkside> cipherzero: sure it can
[08:53] <gonzo__> (We were kids!)
[08:53] <Darkside> which is why you take precautions
[08:53] <Darkside> though it will only ignite if there's a combustible mix
[08:54] <cipherzero> sorry what?
[08:54] <gonzo__> the video did look a bit yellow. Cant all be burning latex?
[08:55] <cipherzero> I mean if the balloon rubs against itself when filling, is that enough?
[08:56] <Darkside> probably not
[08:57] <gonzo__> youi nmean static? If the balloon only has h2 in, it's pretty inert. If you filled with a mix, or the balloon bursts and mixes with air, then you have a risk
[08:57] <gonzo__> but if there is just a burst, the H2 tends to go away all by itself.
[08:58] <Trieste> on a related note, how dangerous is it really? is it still just a huge bang at HAB volumes, or something more dangerous?
[08:58] <cipherzero> No, I mean when you have pure h2, no cigarette, fire or electronics near it and are filling the balloon, can your hands/the balloon itself, the filler head cause something
[08:59] <cipherzero> *"nozzle", i think its called in english
[09:00] simium (c33533bb@gateway/web/freenode/ip. joined #highaltitude.
[09:02] <gonzo__> A little waterbomb/balloon (size of a fist) with just H2 just goes pop. A party balloon with a good H2/O2 mix will go off like a shotgun
[09:02] <gonzo__> I expect a wx balloon will go woof, but it's the burning latex that is the bigger hazard
[09:03] <cipherzero> Or is the only thing I should worry about then if the balloon will rub against the tank wall?
[09:03] <gonzo__> cipherzero, I expect that as long as you don't have any leaks, so no H2/air mix, you are pretty safe. Ant static spark inside the balloon shoudl not be able to cause ignition, as it is pure H2
[09:04] <gonzo__> outside the balloon, there should be no H2
[09:04] <craag> static electricity is only going to cause a problem if it's inside the balloon AND there's oxygen inside the balloon.
[09:04] <daveake> The video I saw, of a wx balloon filled with H2 and ignited by a flame, did indeed go "whoomf" and flew off with the wind dripping burning latex as it went. The h2 was soon gone. Main risk is the latex.
[09:04] chrisstubbsw (~webchat@host86-177-144-32.range86-177.btcentralplus.com) joined #highaltitude.
[09:04] <cipherzero> well OK. But there's always a little bit of air in any balloon before you dill it, right?
[09:04] <cipherzero> *fill
[09:05] <daveake> Hardly any
[09:05] <daveake> The flammable mixture lasts for just a moment as you start to fill
[09:05] <gonzo__> there is a YT video of a huge h2/O2 mix foil balloon being intentionally (and quite stupidly) lit
[09:05] <cipherzero> so you think its negligible to cause a reaction?
[09:05] <daveake> gonzo__ Yes that one went *bang*
[09:05] <craag> With good precautions, no-one here has had any incident (afaik)
[09:05] <gonzo__> it was impressive
[09:06] <daveake> cipherzero Keep flames away and it'll be fine
[09:06] <craag> Also any H2 leak will go upwards and disperse very quickly
[09:06] <daveake> yup
[09:06] <gonzo__> another one from the same place I think, they were filling party balloons with mix and some fuse. Floating thom out ofte the sports field
[09:06] <cipherzero> Anyone here used hydrogen themselves? Ive heard helium is a lot cheaper in US/Europe, albeit still expensive
[09:06] <gonzo__> with a main road at the end!
[09:06] <daveake> Oh yes, don't inflate indoors
[09:06] <daveake> that would be really stupid
[09:06] <daveake> Yes I use H2 all the time
[09:06] <cipherzero> OK then
[09:07] <cipherzero> And why would you fill a weather balloon indoors? it will hardly pass the doors
[09:07] <daveake> I did get a cylinder of He recently for a public event, which in the end never happened, and I wouldn't use H2 for a foil balloon, but otherwise it's H2 all the way
[09:08] <gonzo__> The net office have a hut out in a field for filling (so they can fill out of the wind) They will often use a fire hood, just in case. But that is all health and safety legistaltuion (overreaction)
[09:08] <daveake> indoors in an industrial building with large shutter doors for example
[09:08] <cipherzero> Oh
[09:08] <cipherzero> And one more thing I just remembered
[09:08] Nick change: jaymzx -> jaymzx_away
[09:08] <cipherzero> If its a very hot sunny day, is that a problem?
[09:09] <cipherzero> by that I mean 38C
[09:09] <cipherzero> and open sky sun
[09:09] <chrisstubbsw> daveake: do you collect you H2 from BOC usually or get it delivered?
[09:09] <daveake> Beyond our experience :p
[09:09] <daveake> chrisstubbsw I collect, 'cos they charge a lot to deliver
[09:10] <chrisstubbsw> Yeah they do! When I enquired about collecting they told me my car wasn't suitable
[09:10] <cipherzero> daveake, was your reply to me?
[09:10] <daveake> Never heard that
[09:11] <daveake> cipherzero, Yes, never gets that hot here! Anycase, not an issue
[09:11] <gonzo__> I just drive with the windows open in case of a leak
[09:11] <cipherzero> UK? :P
[09:11] <chrisstubbsw> Recent ford fiesta, plenty of room. They said it was no problem if my dad picked it up in his kia though... Not much difference in size or anything... Logic...
[09:12] <daveake> There's BOC advice to carry cylinders in an open vehicle, but it's just advice not "must"
[09:12] <daveake> Never had an issue when I roll up in the Shogun
[09:12] <craag> Chatting to one of the BOC guys - there's a lot of advice, and very little is mandatory.
[09:12] <chrisstubbsw> They said a 4x4 was more "appropriate"
[09:12] <daveake> Yep
[09:13] <daveake> :)
[09:13] <cipherzero> The reason I asked was if the strong sunlight would burn the latex
[09:13] <chrisstubbsw> Oh well, will take it back in my car and demonstrate there is no problem
[09:13] <craag> He drove around without compressed gas labels on, got pulled over a lot, but wasn't in the wrong.
[09:13] <chrisstubbsw> *breaks back*
[09:13] <gonzo__> the only real precaution worth noting with H2... Don't 'snift' the bottle. That means, to open the valve without the regulator fitted, to clear and dirt from it. Just brush the valve and threads instead
[09:13] <daveake> If it's the big H2 cylinder, you *really* need a flat loading area
[09:13] <daveake> So if the back of the car has a lip it's probably not going int
[09:13] <daveake> in
[09:14] <daveake> 70kg remember
[09:14] <cipherzero> Yeah...
[09:14] <gonzo__> the balloon will be in FAR stronger sunlight when it gets into the upper atmosphere, than it will ever get on the ground
[09:14] <daveake> Ideal: a 4x4 with a big lump of metal for a bumper :)
[09:14] <gonzo__> and theywill still hold up for a day
[09:15] <cipherzero> I'll see if I can source h2 cylinders from the university. I have a balloon guy who has been filling balloons for decades but hes only used helium and methane

[12:14] <Boelle_DK> if you want it down and not a sec. trip arround
[12:14] <Boelle_DK> in fact i'm just currious about the APRS system, i have seen it can work both ways but cant quite figure how it would be done
[12:15] <Boelle_DK> there are these kits that give you a small display and a ps2 connector for keyboard
[12:15] <mattbrejza> high power laser cutdown ftw

[12:18] <mattbrejza> the balloon can listen to aprs just like anything else

[12:19] <Boelle_DK> not a leo spec.... just a genral Q...
[12:19] <Boelle_DK> i might need it to get a permit for launch, if at all the danish auth will issue one

[12:36] <mfa298> If it's related to a permit you may be better off with something like a timed cutdown or geofence cutdown.

[15:27] <eroomde> yes
[15:27] <YO9ICT> Yes
[15:28] <N2NXZ> What is best for soalr?
[15:29] <N2NXZ> solar
[15:29] <mightymik> I have a meter that needs a new set of betteries ...
[15:30] <eroomde> N2NXZ, do you mean that you wan't something rechargeable to make a combined solar/battery power unit?
[15:30] <N2NXZ> Yes
[15:31] <N2NXZ> I have Li-ions and made a pack to test,it lasted 19.5 hours with no assistance...then again,ground temps too.
[15:32] <eroomde> I think most people use lithium-polymer, those who've done it probably have opinins about brands, in general rechargeable batteries don't have the low-temperature performance of lithium prime cells so you need to think about thermal management a bit more
[15:32] <N2NXZ> Yes...but also have lasting power for at least 3-4 days

[15:33] <N2NXZ> I like indefinate
[15:34] <N2NXZ> 19.5 hours should give soalr time to work during daylight I assume?
[15:34] <N2NXZ> solar...wow

[18:16] <mfa298> sounds like it could be some dodgy mtu settings for the ipv6 (interface needs to be small enough to be encapsulated in the IPv4 packets (which may not be the standard 1500 either)

[18:21] <cm13g09> go figure!
[18:21] <craag> wut
[18:22] <maxmed> My code now seems to pretty much work! It transmits the gps data and saves it to the sd card. It still seems to have problems getting the altitude (says it is 9999999m which means its not yet been determined) but gets there eventually. The other problem is when it loses the gps lock the message it keeps transmitting is doggy and missing lots of the information rather than the last "good" data. Any suggestions how to fix this?

[19:30] <nigelvh> Then again, the HE tunnel server I'm using is here in the city, so I'm not far from it.
[19:31] <fsphil> my isp does native ipv6 and have a tunnel service for people without compatible routers
[19:32] <cm13g09> lots of ISPeople here ;)
[19:32] <nigelvh> I have Comcast, and they've been working on native IPv6. I was using it for a while, but it started acting really shitty and, for example, just stop routing properly. So I went back to HE.
[19:33] <mfa298> last time I tried asking my ISP about IPv6 they told me not to worry as they had plenty of IPv6. Although this was just after the IPv6 launch day and I mentioned the rate IPv6 addresses were declining.
[19:33] <mfa298> (They do also give me a /29 to use)
[19:34] <fsphil> I've more ipv4 addresses than I need atm, but don't tell them :)

[19:44] <nigelvh> Yeah, I would guess "bad stuff"(TM)
[19:44] <mattbrejza> actually not sure what vin max is for those
[19:44] <harvy> I looked at the datasheet and it looks like it should be ok
[19:44] <harvy> http://www.radiometrix.com/files/additional/NTX2B.pdf
[19:44] <harvy> page 3
[19:44] <harvy> it claims the max voltage is VCC
[19:44] <mfa298> supply is listed as 2.9 - 15V
[19:45] <mfa298> and enable I think it anything up to the supply voltage
[19:45] <mattbrejza> but if you hadnt connected anything to vcc then vcc will be 0V
[19:45] <nigelvh> Yeah, if EN goes higher than VCC, that would be bad.
[19:45] <harvy> That's what I thought, I'm stumped then.
[19:45] <harvy> I am using the same for both VCC and En.
[19:46] <nigelvh> Did you have a load connected to the output?
[19:46] <harvy> I tried wiring it up to a 12V supply and it just didn't work, so reverted back to 5 and it stopped working.
[19:46] <harvy> @nigelvh what do you mean by output? The transmitter?
[19:46] madist (madist@unaffiliated/madist) left irc: Read error: Connection reset by peer
[19:47] <nigelvh> Yes, on the antenna connection, what was attached?
[19:47] <harvy> No antenna, just breadboard.
[19:47] <nigelvh> That could be it.
[19:47] <nigelvh> NEVER NEVER NEVER NEVER NEVER run a transmitter without an antenna or a dummy load resistor
[19:47] <mfa298> looks like it's an LDO to 3V internally so most of that extra voltage will just be turned into heat.
[19:48] <harvy> It's been running fine without an antenna for a few weeks now.
[19:48] <harvy> Even habwiki, states it can be run without one for testing.
[19:48] <mikestir> it'll be fine - it's only 10mW
[19:48] <craag> nigelvh: The NTX2s are fine without an antenna, they're only 10mW and built like bricks.
[19:48] <craag> bad practice I agree
[19:48] <nigelvh> Eeeeeh. I don't trust that.
[19:48] <mfa298> ntx2 should be fine with no antenna although it's generally not the best design
[19:48] <nigelvh> Especially if you're pushing higher voltages in to begin with.
[19:49] <mikestir> high vswr is only a problem due to excessive dissipation, so it's unlikely to do any harm to a small tx like that
[19:49] <harvy> So what's the chance higher voltages w/o antenna could've fried it?
[19:49] <mfa298> harvy: what voltage range were you feeding into the TXD pin
[19:50] <harvy> TXD pin was from arduino pins, not sure but pretty low.

[19:51] <mfa298> P3 does suggest that high voltage on TXD would also be OK but I don't think the modulation will change once TXD > 3V
[19:51] <mfa298> (high being up to 15v)
[19:52] <harvy> I think it can draw the full arduino load, so 5v on TXD.
[19:53] <harvy> I put the multimeter across some of the pins and I couldn't get any resistance. Is that expected?

[20:14] <harvy> mikestir: I figure that if there is no resistance, something has gone horribly wrong (unless it's a transformer or something).
[20:14] <harvy> Hmmm any ideas on how I can debug this?
[20:14] <mikestir> by no resistance I take it you mean it reads as open circuit (very high resistance)?
[20:14] <N2NXZ> Anthony,I sent to gmail...there are more I need to read and send you still
[20:15] <harvy> mikestir: Yep open circuit.
[20:15] <mikestir> there are plenty of circuits that will read open circuit on a DVM
[20:16] <mfa298> I wouldn't be surprised if both working and dead NTX2's showed open circuit accross various pins
[20:16] <nigelvh> AC coupling will do that.
[20:16] <mfa298> if it was 0 ohms then that could indicate a problem (but even then could be normal)
[20:16] <mikestir> yes reading 0 ohms to ground would be more likely to indicate a problem

[20:46] <lz1dev> they have a tracker that's smaller than a nail
[20:46] <lz1dev> impressive
[20:47] <harvy> mikestir: just using arduino voltage for now
[20:47] <maxmed> is there a way to include extra zeros in the sentance_id/count for my snprintf function so that it is always 6 digits, ie. 000465 rather than 465?
[20:47] <harvy> mikestir: so 5 or 3.3
[20:47] <lz1dev> maxmed: yes
[20:47] <mikestir> harvy: repeat the test on 3.3V and if you don't get the same current then it's probably bust
[20:48] <mikestir> because it has a linear regulator built in, so the current should remain constant
[20:48] <lz1dev> maxmed: %06d is what you need
[20:49] <maxmed> forgot to mention it is a unsigned long if that matters
[20:49] <harvy> mikestir: same current
[20:49] <lz1dev> maxmed: so you are using %f then
[20:50] <mikestir> ok that means the regulator is working then. 30mA is high though. are all other pins (apart from the grounds) unconnected?
[20:50] <maxmed> at the moment I'm using %lu
[20:51] <mikestir> maxmed: %06lu then
[20:51] <mikestir> why do you want 6 digits for sentence id though?
[20:51] <maxmed> ok, thank you, so I'm guessing if you wanted 8 digits it would be %08lu ?
[20:52] <lz1dev> exactly
[20:52] <lz1dev> if you want other char for padding replace 0

[20:58] <lz1dev> camera audio
[20:58] <maxmed> mikestir: maybe that would be easier but it is hard to know when the data was last good, it seems the data gets corrupted due to poor signal faster than it can realize the data is bad. I did think about trying to read the sd card and transmit the last couple of values but couldnt figure out how to read the latest 3 lines from the sd card
[20:59] <amell> audio has not arrived yet?
[20:59] <Upu> not yet amell
[21:00] <amell> fsphil: have you got your 1000 element yagi sweeping back and forth for the Bs yet?
[21:00] <harvy> mikestir: Just a pin on the arduino
[21:00] <Upu> probably going to be our Southern Stations that get it first
[21:00] <mikestir> maxmed: after you populate the gps variables from tinygps, check fix age and number of satellites to see if they look valid, then if they are then copy them all into a copy set of variables
[21:00] <mfa298> maxmed: I'd probably do it by having a set of variables to keep the last known good values. Then when you get new data check if it's valid and if it is update the last known good values. Each time you transmit you can use the last known good values
[21:00] <mfa298> mikestir: snap
[21:01] <mikestir> the data isn't being corrupted because of failure to keep up. what you are probably seeing is tinygps getting confused because you stop to transmit your sentence and miss a load of NMEA data from the gps
[21:01] <amell> Im a little surprised it got to Nuuk already
[21:01] <Upu> faster winds
[21:02] <Upu> it was inline with the prediction
[21:02] <lz1dev> if they heard b63
[21:02] <lz1dev> there is hope
[21:02] <amell> there is always hope when there is a B in the air
[21:03] <mikestir> harvy: measure it with tx open circuit
[21:03] <amell> Have we given up on B-66 yet? Im surprised its still on the map.
[21:04] <amell> B-66 has exceeded all reasonable hysplit forecasts.
[21:04] <mikestir> harvy: also measure with the enable pin disconnected
[21:04] <Upu> no reason to take it off just yet
[21:05] <amell> Looks like B-63 should be audible in UK 6am onwards on thursday morning according to that Hysplit.
[21:06] <jcoxon> it'll hit aprs first is suspect
[21:06] <jcoxon> i*
[21:06] <amell> I thought aprs would be turned off before we get it.
[21:06] <Upu> yeah Ireland
[21:06] <Upu> its fine over Ireland
[21:06] <amell> ireland has aprs enabled?
[21:06] <jcoxon> nah it'll be on over the sea and with a good hundreds km range
[21:06] <Upu> No idea but its airborne ok there
[21:06] <Upu> not Northern Ireland
[21:06] <jcoxon> it'll scrap the UK aprs network (well at least its done that as they normall leave
[21:07] <amell> confirmed if geofence enables aprs over ireland?
[21:07] <Upu> I have no idea amell I didn't write the code
[21:07] <amell> Leo must be getting excited.
[21:07] <mikestir> it should be in range even before it makes land - I had some packets from a B on my igate while it was over the north sea
[21:08] <amell> My worry is that if he does succeed, he will stop launching, because mission accomplished.
[21:08] <F1VJQ> off southern France the APRS cut in after just a few km offshore
[21:08] <jcoxon> amell, we'll just challenge him to cross the equator
[21:08] <maxmed> mikestrir/mfa298 : I've written the code using my method so will test it and see how reliably it works, if it proves ineffective I'll create a dublicate set of "good values" but it introduces quite a few extra variables. but saying that my method involes creating a second substring variable which is quite large
[21:08] <amell> jcoxon: id like to see some pico camera payloads :)

[22:13] <mattbrejza> well i was gonna say yes
[22:14] <mattbrejza> didnt think this would turn philosophical

[22:21] <N2NXZ> He did not send the link yet...lol
[22:21] <F1VJQ> Oh bother!!
[22:22] <N2NXZ> I am patiently waiting for the reply and check my emails every 1 minute.
[22:22] <jcoxon> haha
[22:22] <mattbrejza> how sure are we that this is a B-6*?
[22:23] <N2NXZ> I have my audio sttings ready and Igate up and running...actually,has been awhile,all I need is the audio and hope it is good enough to decode
[22:23] <jcoxon> okay

[23:12] <fsphil> so I'm not sure how they know it's a B
[23:13] <fsphil> but more importantly there's a town called Moose Factory in Canada. Which is just a great name.
[23:13] <N2NXZ> I am still working on the audio,using another program or 2 in hope one will work

[23:34] <F1VJQ> Timed earlier today but just appeared? Is that back data from N2NXZ?
[23:35] <F1VJQ> B-64 was due there first ...
[23:35] <craag> It was an audio recording emailed to and decoded by Leo
[23:35] <LeoBodnar> i believe it is from OX3XR decoded by DL7AD
[23:35] <craag> ah
[23:36] <craag> Yeah B-64 might have skipped over unheard..
[23:36] <DL7AD> yeah decoded first by me but N2NXZ was in the same conversation
[23:36] <DL7AD> l
[23:36] <LeoBodnar> this is B-64
[23:36] <craag> heh so it is

[23:39] <F1VJQ> B-63 will be in that area about now based on the gap between them losing APRS in Newfoundland
[23:39] <F1VJQ> wonders if there is any APRS in Greenland
[23:40] <LeoBodnar> there should be now
[23:41] <F1VJQ> has OX3XR got igate?
[23:41] <F1VJQ> or maybe others
[23:41] <amell> Holy fuck. Where did that data point come from
[23:42] <amell> Ah. [APRS64 via WIDE2-1,qAR,DL7AD]
[23:42] <F1VJQ> amell an audio recording earlier
[23:42] <amell> thought you couldnt decode the audio
[23:42] <F1VJQ> decoded by DL7AD
[23:43] <amell> 54 degrees west. nice!
[23:44] <LeoBodnar> 2nd video
[23:44] <amell> arko: something wrong with your hysplit? shows a fast descent to 10Km?
[23:44] <arko> yeah i dont understand that
[23:44] <amell> arko: needs to be AMSL too.
[23:44] <LeoBodnar> it's AGL plot
[23:44] <arko> hmm
[23:44] <arko> that weird
[23:44] <arko> i thought i did select AMSL
[23:45] <amell> so theres a 2km high mountain at the bottom of greenland.
[23:45] <F1VJQ> LeoBodnar I wonder what listening stations there are for ships? AIS
[23:45] <LeoBodnar> it's correct arko you just plotted agl
[23:45] <arko> oh!
[23:45] <arko> derp
[23:45] <arko> :)
[23:45] <LeoBodnar> well it's fine
[23:45] <arko> man, greenland is so beautiful to fly over
[23:46] <arko> truely one of the most amazing things i've ever seen
[23:46] <arko> or really northern canada
[23:46] <arko> its like another world
[23:46] <F1VJQ> no green fields full of corn?
[23:46] <F1VJQ> or sunflowers!!
[23:46] <arko> lots of ice :)
[23:47] <arko> get to see it again in 2 weeks :D
[23:47] <F1VJQ> yeah...all that cold would drive me bonkers
[23:47] <adamgreig> really northern canada is crazy
[23:47] <amell> thursday evening- midnight then for B-64
[23:47] <arko> hehe, i bet
[23:47] <adamgreig> the crazy terrain in nunavut and nwt
[23:47] <F1VJQ> soon as that amell?
[23:47] <adamgreig> i was up in dawson city yukon last year and that was cool enough
[23:48] <DL7AD> http://en.wikipedia.org/wiki/Around_the_World_in_Eighty_Days
[23:48] <amell> It makes landfall in france at 0000 1st August according to that last hysplit.
[23:48] <amell> Im guessing it will come into range earlier.
[23:50] <amell> Im also guessing that it wont be an official circumnavigation until it passes the longitude of silverstone.
[23:50] <LeoBodnar> haha "Although a journey by balloon has become one of the images most strongly associated with the story, this iconic symbol was never deployed by Verne  the idea is briefly brought up in chapter 32, but dismissed, it "would have been highly risky and, in any case, impossible."
[23:51] <amell> around the world in 22 days?
[23:51] <LeoBodnar> 18 so far
[23:51] <F1VJQ> amell I'm not using mobile vsn.. have you a link?
[23:51] <amell> F1VJQ: to what?
[23:52] <F1VJQ> the hyslpit

[23:53] <F1VJQ> thanks
[23:53] <amell> F1VJQ: That was an arkoed URL btw.
[23:54] <F1VJQ> a bit further south than thought earlier
[23:54] <LeoBodnar> things might change yet
[23:54] <amell> anybody who can record audio on the east coast of greenland?
[23:55] <LeoBodnar> arko: that datapoint was 1800 UTC
[23:55] <LeoBodnar> not 2300
[23:55] <F1VJQ> if it misses UK it will be a shame, but I may get to hear it over Brittany
[23:55] <arko> hmm
[23:55] <amell> ah. new hysplit required
[23:55] <arko> the graph starts around 23 no?
