[00:00] <daveake> I liked Voyager
[00:00] <nigelvh> I liked enterprise with picard and voyager.
[00:00] <nigelvh> daveake knows where it's at.
[00:00] <fsphil> voyager had moments
[00:00] <Lunar_Lander> Archer was interesting too
[00:00] <daveake> Best intro sequence
[00:00] <fsphil> but apart from the Doc and 7of9, I didn't really like the crew
[00:01] <daveake> I figured that all my fave characters were artificial
[00:01] <daveake> Doc ... Data
[00:01] <nigelvh> Yes, those were my favorite chars, but I do feel like janeway was an interesting character as captain.
[00:01] <daveake> Mind you .... Seven ...
[00:02] <fsphil> pretty much all the characters in DS9 where really interesting
[00:03] <fsphil> some of the best acting too
[00:04] <nigelvh> I liked in picard's series that picard and riker were really the two halves of captain kirk. riker had the "sleep with alien women" and "act on impulse" parts, and picard had the "good captain" and "best for the crew/ship decision making"
[00:05] <fsphil> hah, interesting idea

[00:06] <nigelvh> So, for me the eternal question about who the better captain one is always picard. He was designed to be THE CAPTAIN. Kirk was a dude who was also good at being a captain.
[00:07] <daveake> Every time Picard said "Shoot at will" I wanted the cast to get out their phasers and zap Riker
[00:07] <fsphil> or Wesley
[00:07] <daveake> Esp Wesley
[00:08] <nigelvh> Hahaha!
[00:08] <daveake> But his name wasn't Will

[00:09] <arko> picard is better looking and more relatable, thus he wins.
[00:10] <fsphil> the actor was called Wil, close enough
[00:10] <daveake> Ah yes
[00:10] <arko> he's a very nice guy irl btw
[00:11] <arko> met him at a resturant a few weeks ago
[00:11] <fsphil> he is that
[00:11] <daveake> Was on Big Bang Theory once
[00:11] <nigelvh> Yes Wil Wheaton
[00:11] <arko> yeah, oddly he actually lives around the area
[00:11] <nigelvh> He is internet famous
[00:11] <arko> not sure if pasadena exactly
[00:11] <nigelvh> Also was in Dr. Horrible's Sing Along Blog which was fantabulous

[00:12] <fsphil> that was great
[00:12] <OZ1SKY_Brian> SKYHAB RTTY TEST BEACON*BCF2 :-)
[00:12] <Lunar_Lander> cool!
[00:12] <fsphil> I miss Firefly :)
[00:12] <Lunar_Lander> well done
[00:13] <OZ1SKY_Brian> pressing on
[00:13] <arko> fsphil: please, it hurts to remember
[00:13] <arko> died so young
[00:13] <nigelvh> The movie was good too though
[00:14] <arko> yeah
[00:14] <fsphil> it was a foxing shame, those foxing foxers at fox

[00:14] <nigelvh> Futurama makes an excellent joke about fox. "Everyone knows that any show that's remotely good gets cancelled. Sometimes two or three times."
[00:15] <chrisstubbs> Im off guys! cheers for the help Lunar
[00:15] <fsphil> have Fox ever taken a show to a natural conclusion?
[00:16] <nigelvh> That's an excellent question...
[00:16] <fsphil> the Simpsons probably has no end
[00:16] <fsphil> and it's looking like Family Guy doesn't either
[00:16] <fsphil> but I can't think of any shows they've made that properly ended
[00:16] <fsphil> maybe Fringe

[00:17] <fsphil> oh the x-files was fox
[00:21] <Laurenceb_> that was definitely not taken to any conclusion :P
[00:21] <fsphil> haha
[00:21] <Laurenceb_> still it made more sense than lost
[00:22] <Laurenceb_> i think the lost writers just took more and more drugs as time went on
[00:22] <fsphil> I enjoyed the first series of that, when they hadn't revealed that much
[00:23] <fsphil> after that it was clear they had no idea

[00:24] <fsphil> Charlie Jade did that a bit too ... fantastic concept for a show, but the story just got weirder and less interesting towards the end

[00:59] <Lunar_Lander> they said you can get good boxes at pharmacies
[00:59] <Lunar_Lander> so I went to ours and they looked like ??

[08:11] <arko> waiting for my static ips
[08:11] <oh7lzb> Could even title it APRS packet decoder
[08:11] <arko> damn isp taking forever
[08:11] <arko> yeah
[08:11] <arko> oh7lzb :)
[08:11] <oh7lzb> since it parses all formats.
[08:11] <arko> yeah
[08:11] <arko> did you write HAM::APRS::FAP?
[08:12] <oh7lzb> OH2KKU wrote it, I added wx parsing, some other formats, granular error reporting in the api, and act as the release engineer :)
[08:12] <oh7lzb> After the discussion we had previously I was thinking of maybe doing exactly what you did and putting it on aprs.fi
[08:13] <arko> oh7lzb you guys totally should
[08:13] <arko> also cool :)
[08:13] <oh7lzb> but got other stuff to do first :)
[08:14] <arko> hehe, you guys have done a fantastic job with aprs.fi
[08:14] <oh7lzb> like, some painting of walls here.
[08:14] <arko> btw
[08:14] <oh7lzb> Thanks.

[08:21] <arko> i'm getting a static ip soon and will probably have a different domain in a couple days, but i will have this one forward to the new
[08:21] <oh7lzb> A little idea: Could put a <pre> block around the raw decoded output to make it more readable
[08:21] <arko> oh good idea
[08:21] <oh7lzb> for the newlines and indentations that Data::Dumper produces
[08:21] <oh7lzb> => gone now

[08:24] <arko> it's become an unhealthy obession with projects
[08:24] <nigelvh> Also think you did a real pretty design of the site as well
[08:24] <arko> haha, thanks
[08:24] <arko> blended two themes and some photoshop
[08:25] <nigelvh> My site is just a basic wordpress with a clean theme that I stuff my projects into.
[08:26] <arko> nice
[08:26] <arko> link?
[08:26] <nigelvh> digitalnigel.com
[08:27] <arko> reloading!
[08:27] <nigelvh> really, the "Projects" sidebar bit is horribly out of date.
[08:27] <arko> oh man, that is some of the most calming stuff
[08:27] <nigelvh> Everything's just in the post.
[08:27] <nigelvh> posts*
[08:27] <arko> oh you're the Iris folks?
[08:27] <nigelvh> Iris folks? I just designed a transmitter and called it iris.
[08:28] <arko> hmm
[08:28] <arko> i thought there was a hab that had something with the name iris in it
[08:28] <nigelvh> Entirely possible
[08:28] Action: arko has seen too many hab names after staring at data
[08:29] <nigelvh> Yeah, I don't really bother to keep track of the balloon names
[08:29] <arko> so many
[08:29] <nigelvh> Generally we do two launches a year, so it's 2012 A and B.

[08:30] simrun (~simrun@gateway/shell/freebnc/x-lirfhbumknkdmrfa) joined #highaltitude.
[08:31] <nigelvh> Anyway, the transmitter has been my big project of late. It's working pretty good. Hopefully in the spring I'll throw it on a pico flight.
[08:31] <arko> what freq is it?
[08:32] <arko> oh 144
[08:32] <arko> and down
[08:32] <nigelvh> I designed it to be pretty agile. If I change out the filters, it can do the 2m/1.25m/70cm/33cm amateur bands.
[08:32] <arko> oh nice
[08:32] <nigelvh> Though, so far I've only tested on the 2m band.
[08:33] <nigelvh> In fact, I should get a bit more power output at the higher bands.
[08:33] <arko> hmm
[08:33] <arko> whats your synth?
[08:33] <arko> rf synth
[08:33] <nigelvh> ADF7012
[08:33] <arko> no
[08:33] <arko> freakin
[08:33] <arko> way
[08:33] <arko> i wrote drivers for that at my old job
[08:33] <arko> that things does everything!
[08:33] <arko> so many settings
[08:34] <nigelvh> Yeah, it's pretty flexible
[08:34] <Upu> morning
[08:34] <nigelvh> Morning upu

[08:34] <arko> Upu: http://mice.habexproject.org
[08:34] <arko> if you want to test it out
[08:34] <nigelvh> Though, I mostly under-utilize it. I set a frequency, and then modulate the FM with a VCXO
[08:34] <Upu> yeah saw that arko looks good
[08:35] <arko> nigelvh neat
[08:35] <arko> clean design too
[08:35] <Upu> oh clicks you're N6ARA :)
[08:36] <nigelvh> Yeah, I think this revision came out pretty well.
[08:36] <arko> Upu :)
[08:37] <arko> nigelvh: looked like an ardupilot from far away :P
[08:37] <arko> i dig the purple pcb
[08:37] <nigelvh> oshpark.com
[08:37] <nigelvh> cheap PCBs if you're willing to wait
[08:37] <arko> holy purple batman
[08:37] <arko> nice
[08:38] <arko> thats pretty damn good
[08:38] <nigelvh> Also in small quantities. You get to very many and it makes more sense to go with a normal fab house.
[08:38] <arko> right
[08:38] <arko> great from prototyping
[08:38] <nigelvh> Yes, but brings to light my love/hate relationship with digikey.
[08:38] <arko> fortunate to have a pcb mill here at our hackerspace
[08:39] <arko> and throughhole platter
[08:39] <nigelvh> Complete a design and send the boards off, order the parts from digikey, parts arrive two days later and boards wait another week or two.
[08:39] <Upu> Mitch is cheaper
[08:39] <Upu> but doesn't do purple
[08:39] <arko> that's really nice for good price
[08:40] <arko> wish i knew about this before :/
[08:40] <Upu> Arko try Mitch he's $18 for 10 x 50mmx50mm
[08:41] <arko> snap
[08:41] <arko> turn around time?
[08:41] <nigelvh> I've got a setup here at home to do single sided etching that works pretty well, but anything double sided or small pitch I send off.

[09:37] <arko> heh, i should.. but x-files..
[09:38] <jcoxon> ping fsphil
[09:41] <jcoxon> question - on aprs packets how is the comment section delimited?
[09:41] <jcoxon> is it ':'
[09:44] <arko> i think it's between the } and the first |
[09:46] <arko> at least for mic-e
[09:46] <G0MJW-PC> Did you look at the APRS 101 from G3NRW?
[09:47] <jcoxon> i'm reading the specs currently
[09:48] <G0MJW-PC> 128 pages!
[09:48] <jcoxon> hehe
[09:48] <jcoxon> its really an issue of identifying the comment in the raw data
[09:48] <jcoxon> some of it seems to be ascii-7 and some ascii-8
[09:49] <G0MJW-PC> Appendix 1 APRS data formats
[09:50] <G0MJW-PC> Is it delimited at all?
[09:51] <oh7lzb> Nope, there is the comment section after the base data section, and then you have to go and try identify additional data extensions from the comment field
[09:52] <oh7lzb> some in beginning, some in the end, and one (mic-e type codes) has some chars both in beginning and end of packet
[09:52] <oh7lzb> what is left after removing all the extensions (PHG, base91 telemetry, altitude...) is the comment
[09:53] <oh7lzb> if your parser doesn't understand some extensions, they are left in the comment for the user to see
[09:53] <oh7lzb> It's a really crappy scheme.
[09:53] <jcoxon> oh7lzb, so i'm getting the decoding the raw data, only the comment is readable
[09:53] <G0MJW-PC> Looking at it (for the first time) I would agree with oh7lzb. But the group bulletin (sic) might be suitable
[09:54] <oh7lzb> There is a status packet too
[09:55] <oh7lzb> >blaablaabla as the minimum form
[09:55] <oh7lzb> can have a timestamp, too
[09:55] <jcoxon> oh7lzb, i'm hacking together an aprs to ukhas standard airborne repeater
[09:55] <jcoxon> which could fly tomorrow
[09:55] <oh7lzb> oh, ok
[09:55] <jcoxon> people send aprs packets and it decodes them and extracts out some data
[09:55] <jcoxon> and downlinks it to spacenear.us etc
[09:55] <G0MJW-PC> Suggest you just echo the entire packet?
[09:56] <jcoxon> G0MJW-PC, my reading of the rules don't allow that
[09:56] <G0MJW-PC> Or just the call and location
[09:56] <jcoxon> actually i don't want the call either
[09:56] <jcoxon> basically the paylod is listening to a ground aprs network :-)
[09:56] <Upu> whats the deal with the -1 on the end of the calls sign
[09:56] <Upu> i.e should I be M0UPU-1 -2 ?
[09:57] <G0MJW-PC> Well you are already testing the rules in the first place. Another minor misdemenour will not add much to your sentence
[09:57] <jcoxon> G0MJW-PC, its not involved
[09:57] <griffonbot> Received email: "Re : Re: [UKHAS] Flight Announcement XABEN-41"
[09:57] <G0MJW-PC> (Might be a good idea to strip the call come to think of it (:
[09:58] <jcoxon> we could put our irc nicks in teh comment
[09:58] <jcoxon> to distinguish who it was
[09:58] <G0MJW-PC> Betterchange mine...
[09:58] <Upu> why is pretty much any page relating to setting up APRS 404 :/
[09:58] <jcoxon> hehe
[09:58] <Upu> Anyone know what the numbers after your call sign relate too ? i.e M3GDW-7 ?
[09:59] <jcoxon> yeah i do
[09:59] <Upu> got a link ?
[09:59] <jcoxon> its to do with what sort of thing you are
[09:59] <jcoxon> e.g. -11 is balloon
[09:59] <G0MJW-PC> This is getting very innovatiove. Are you going to allow in flight firmware updates

[10:01] <Upu> I'm not documenting it
[10:01] <Darkside> whats tomorrow?
[10:01] <Upu> its just a mess that seems to work
[10:01] <Upu> James is launching an APRS repeater of sorts
[10:01] <Darkside> APRS flight romorrow?
[10:01] <Darkside> oh?
[10:01] <Upu> on 70cms
[10:01] <jcoxon> sort of
[10:01] <jcoxon> its a made idea Darkside
[10:01] <jcoxon> mad*
[10:01] <Darkside> hows he getting away with that?
[10:02] <jcoxon> we are going to move aprs network on to 434.075
[10:02] <Darkside> APRS/AX25 is meant to be for amateur use only
[10:02] <Darkside> with 25mW?
[10:02] <jcoxon> and the balloon will listen in
[10:02] <Darkside> 10mW*
[10:02] <Darkside> oh?
[10:02] <jcoxon> and only relay the comments from teh data down on 10mW rtty
[10:02] <Darkside> how are you doing the demodulation ?
[10:02] <jcoxon> nrx2 and a tnc
[10:02] <jcoxon> it won't really work
[10:02] <jcoxon> but its a bit of fun
[10:02] <Darkside> what tnc?
[10:02] <jcoxon> software based
[10:02] <Darkside> arduTNC stuff?
[10:03] <jcoxon> yeah
[10:03] <Darkside> heh
[10:03] <jcoxon> painful i know
[10:03] <Darkside> i dunno how well those work
[10:03] <Darkside> but you can do it with an external data slicer apparently
[10:03] <Darkside> i think you only need zero crossings to decode it
[10:04] <G0MJW-PC> I want to make a proper arduino TNC
[10:05] <Darkside> hehe
[10:05] <Darkside> you could make an opentracker
[10:05] <Darkside> the source for that is open
[10:05] <Darkside> as is the design
[10:05] <G0MJW-PC> I wonder if you can still get those modem chips like a Baycom
[10:05] <Darkside> hard to get hold of
[10:05] <Darkside> really hrd
[10:06] <Darkside> but they do still exist
[10:06] <G0MJW-PC> I have one here - a baycom modem that is

[12:48] <jcoxon> char aprsbuffer[40]; //APRS buffer
[12:48] <fsphil> that looks fine, although I'd check if y >= 40 too
[12:48] <fsphil> and terminate with a null character
[12:50] <fsphil> something like http://pastebin.com/Sar6i6Fr
[12:51] <jcoxon> surely in that example the terminating char will be put every other place in the array
[12:51] <jcoxon> as the while loops
[12:51] <fsphil> y only gets increased once per loop
[12:52] <fsphil> the null gets overwritten by the next char each loop
[12:52] <jcoxon> oh i see
[12:52] <fsphil> although you could just as easily do it after the loop
[12:52] <fsphil> aprsbuffer[y] = '\0';
[12:53] <fsphil> yea that'd be better
[12:53] <fsphil> as it would also work if there was no data
[12:54] <fsphil> http://pastebin.com/bQUzG7QC
[12:54] <jcoxon> i think i'll limit it to 20 rather than 40
[12:54] <fsphil> aprs packets can be fairly long
[12:54] <fsphil> does aprs.read() return the entire packet?
[12:54] <jcoxon> we've already stripped most of the data out
[12:54] <jcoxon> nah the tnc chip isn't passing all teh data on
[12:55] <oh7lzb> aprs packets can technically contain nulls
[12:55] <fsphil> ah then that might be fine

[12:55] <oh7lzb> agwtracker for one transmits utf-16 (or something) 2-bytes-per-char encoded unicode
[12:56] <fsphil> euu
[12:56] <jcoxon> as this is going to be a bit custom i'm not to worried about that
[12:56] <oh7lzb> every other byte being null when transmitting english :)
[12:56] <jcoxon> basically in the comment section you need somethign to be repeated
[12:56] <fsphil> this is why I prefer utf-8 :)
[12:56] <oh7lzb> fsphil: agreed :)
[12:56] <jcoxon> so the tnc is pulling out anything between # and #
[12:56] <jcoxon> e.g. #hi fsphil#
[12:56] <oh7lzb> I pushed Bob to publish a standard saying APRS messages are UTF-8
[12:57] <fsphil> ah so it's official now?
[12:57] <fsphil> in as official as it can be I suppose
[12:58] <oh7lzb> yes
[12:58] <oh7lzb> http://www.aprs.org/aprs12/utf-8.txt
[12:58] <fsphil> I'm not sure I'll be around tomorrow for this launch annoyingly
[12:59] <oh7lzb> but he didn't quite understand how utf-8 works so he put in some questions and ambiquous stuff in the spec...
[12:59] <oh7lzb> as usual, didn't get the difference between unicode and it's encodings
[12:59] <oh7lzb> and bytes vs chars
[13:00] <fsphil> yea the variable length character gets a lot of people
[13:01] <oh7lzb> Btw, I run an UTF-8 APRS message responder for testing utf-8 compatibility, send an APRS message UTF-8 and it'll reply with UTF-8 encoded testing material
[13:02] <fsphil> UTF-8 has a mode to print right-to-left
[13:05] <jcoxon> fsphil, its working
[13:05] <oh7lzb> I'm waiting for someone to translate aprs.fi to some RTL language, then I'll get to the fun of doing a mirrored layout to match :)
[13:06] <fsphil> nice one jcoxon
[13:09] <jcoxon> so
[13:09] <jcoxon> what we are going to do is send aprs packet on 434.075
[13:09] <jcoxon> in the comments section put a message between two #s
[13:09] <jcoxon> if the balloon hears a packet it'll decode it
[13:09] <jcoxon> and extract that message
[13:09] <fsphil> will it accept any kind of message?
[13:09] <jcoxon> and it'll appear on the downlink
[13:10] <fsphil> fldigi can send messages, but I'm not sure what kind of packet format it is
[13:10] <jcoxon> nah its going to need to be fm packet
[13:10] <fsphil> yea, the upstream version from git supports packet
[13:10] <jcoxon> oh right
[13:11] <fsphil> but I've no idea how it actually constructs the packet from the text entered
[13:11] <jcoxon> so ive been testing with xastir
[13:11] <jcoxon> just adjusting the comment section

[13:15] <fsphil> ah, so it should work with any packet type
[13:15] <Darkside> bit of a hack
[13:15] <jcoxon> the whole thing is a hack!
[13:16] <Darkside> :P
[13:16] <fsphil> what compiler does arduino use? I don't seem to have an avr-g++
[13:16] <Darkside> jcoxon: at least you're not listening on the main APRS freq
[13:16] <Darkside> that would be bad
[13:16] <jcoxon> indeed
[13:20] <jcoxon> hehe this should be fun
[13:20] <jcoxon> even if it doesnt work
[13:21] <Darkside> so when is this launching?
[13:21] <jcoxon> tomorrow
[13:21] <jcoxon> :-p
[13:21] <Darkside> cool
[13:21] <fsphil> you're nearly as bad as me jcoxon
[13:21] <jcoxon> well i've got backup though
[13:21] <jcoxon> as xaben is on the train as well
[13:22] <jcoxon> so i can do the crazy stuff
[13:22] <griffonbot> Received email: Geoff Mather "[UKHAS] Re: external battery for Canon PowerShot"
[13:22] <fsphil> that's what I loved about my first launch -- I wasn't the only one, could be a bit nuts and do silly things like 300 baud :)
[13:22] <Darkside> 300 baud silly?
[13:22] <Darkside> :P
[13:23] <jcoxon> so for my antennas
[13:23] <fsphil> at the time :)
[13:23] <jcoxon> best to keep them more then a wavelenght apart
[13:23] <Darkside> uh oh
[13:23] <Darkside> you're downlinking on 70cm too aren't you
[13:23] <Darkside> continuously
[13:23] <jcoxon> yup
[13:23] <Darkside> thats going to wipe out the uplink
[13:23] <Darkside> it won't work
[13:23] <fsphil> you'll need a gap
[13:23] <Darkside> you'll need more than a cap
[13:23] <Darkside> gap
[13:23] <Darkside> we needed about 5m
[13:23] <fsphil> minutes?
[13:24] <Darkside> metres
[13:24] <fsphil> ah, I'm thinking time gap
[13:24] <Darkside> else the downlink would desense the uplink
[13:24] <Darkside> oh wait
[13:24] <Darkside> not full duplex
[13:24] <Darkside> or is it?
[13:24] <Darkside> because if its downlinking continuously, you're going to have trouble receiving
[13:24] <Darkside> this is why all our repeaters are crossband
[13:24] <Darkside> you can't get enough isolation if they're both on the same band
[13:24] <jcoxon> so we can go for a gap
[13:25] <jcoxon> in time that is

[13:25] <Darkside> yep
[13:25] <Darkside> thats how i handle my uplink payload too
[13:26] <jcoxon> if so how far do i need to place the antennas?
[13:26] <Darkside> oh
[13:26] <Darkside> uhm
[13:26] <jcoxon> as they aren't operating together
[13:26] <Darkside> a wavelength apart sounds about right i guess
[13:26] <Darkside> dunno how you'll do that
[13:26] <Darkside> maybe make a small j-pole for the uplink antenna
[13:26] <jcoxon> so i could leave the rx running all the time
[13:26] <Darkside> or slim jim
[13:27] <jcoxon> but leave a tx gap to allow packets to get through
[13:27] <Darkside> for downlink use the standard 1/4 wave, uplink use a 70cm slim jim above the payload on the line
[13:27] <Darkside> you can make them out of ribbon cable easily
[13:29] <jcoxon> i initially thought about having them slight extended out the sides of the payload
[13:29] <jcoxon> but i guess teh rotation would be weird
[13:29] <Darkside> yeah probably dont do that
[13:30] <Darkside> one above the other
[13:30] <fsphil> yea we had one at the bottom and another on the top once

[13:46] <fsphil> You'd think with the time it takes me to get a notam, I'd be ready months early :)
[13:46] <jcoxon> still need to construct antennas
[13:48] <fsphil> I'm not sure what I did differently with my last antenna, but the signal was great

[16:15] <domlin> and im not sure, chris showed it to me, i believe a russian man made it?
[16:15] <Upu> I need to make one
[16:15] <Upu> I've broken my Diamond
[16:15] <eroomde> the huge one?
[16:16] <domlin> ohh they're expensive arent they?
[16:16] <Upu> no just the small one I used to use for DFing payloads
[16:16] <eroomde> ah
[16:16] <Upu> I wired it up a pole and it fell over and took the reflector with it
[16:16] <domlin> oop
[16:16] <eroomde> yeah for DFing you can make one that's optimised for things better for DF-ing
[16:16] <Upu> its sort of taped up with gaffer at the moment
[16:16] <eroomde> i.e. front to back ratio rather than absolute gain
[16:17] <eroomde> which can be a blessing
[16:18] <domlin> btw guys finally decided to get a laptop that can handle sdrsharp and dlfldigi running at the same time with no issues :P
[16:18] <eroomde> nice
[16:18] <eroomde> what are you going for?
[16:18] <domlin> ah i got one already...
[16:18] <DrLuke> I just bought a yagi, I figured it was cheaper and better than anything I could ever make: http://i47.tinypic.com/2yux5iq.jpg
[16:18] <domlin> unfortunately it's a HP
[16:18] <fsphil> at least it's not an apple
[16:18] <eroomde> my friend who works for a fancy startup in the US came to visit 2 days ago. they'd given him a completely top of the line macbook pro retina
[16:18] <eroomde> with 2GB graphics at 768GB SSD and all sort
[16:19] <DrLuke> nice
[16:19] <eroomde> but it was v delicious to use
[16:19] <domlin> ohh jealous :(
[16:19] <eroomde> i wouldn't mind that, but whern i specced it up it was about £2500
[16:19] <DrLuke> they actually maked SSDs that big?
[16:19] <eroomde> on the macbooks its just flash chips soldered to the logic board
[16:19] <DrLuke> half of that price probably was the SSD alone, lol
[16:19] <fsphil> yea, but most of that £2500 is probably the SSD
[16:19] <eroomde> not upgradeable
[16:19] <domlin> probably just loads of microsd's in a project enclosure...
[16:19] <fsphil> that kinda sucks
[16:20] <fsphil> so you can't change the battery, or the ssd?
[16:20] <eroomde> the screen is lovely though. it has two thunderbolt ports so you could plug in a pair of 2560x1440 monitors and daisy chain a raid array
[16:20] <eroomde> which would be a wet dream for photo editing
[16:20] <eroomde> fsphil: correct
[16:20] <fsphil> shame
[16:20] <Randomskk> almost don't need the raid array with that much ssd
[16:20] <fsphil> I do want a monitor with decent resolution
[16:20] <fsphil> my new monitor has lower vertical resolution than my old one :(
[16:21] <Randomskk> eroomde: and what do they use it for, textmate and chrome? :P
[16:21] <eroomde> Randomskk: it's Henry!
[16:21] <eroomde> tronics
[16:21] <Randomskk> ooh, is he still doing the microsatellite radio stuff?
[16:21] <eroomde> yep
[16:21] <Randomskk> cool
[16:21] <domlin> YAGI appears to be working... going to go waste some petrol to try it out :)
[16:22] <Randomskk> all the devs at my old job had fancy macbooks (or sometimes mba) and very much just needed vim and a web browser >.>
[16:22] <Randomskk> though to be fair
[16:22] <Randomskk> rails
[16:22] <Randomskk> so just running the test suite is cause for a cup of coffee
[16:22] <eroomde> i think the horsepower would be useful with a pair of big monitors
[16:23] <eroomde> but yeah, not so important for embedded software of electronics design
[16:23] <eroomde> though again, just using eagle on a laptop screen that nice was a pleasant thing
[16:23] <Randomskk> I bet

Dissolve the sodium-bicarbonate in the warm water, add the ammonium nitrate and dissolve it. Add the table sugar and gently boil until it will be a darkbrown goo.

[16:54] <Hiena> The ammonium-nitrate and the sodium-bicarbonate form sodium-nitrate and amonium-carbonate. Over 42 Celsius the ammonium-carbonate decompose to ammonia and carbon-dioxid. The ammonia form ammonia caramell with the sugar, and the others boils away with the water.
[16:58] <Hiena> The whole process could be run around 100 Celsius, and the materials kept in liquid or semi liquid form. So there is no chance for the self ignition.

[17:57] <domlin> why would it only just have started happening for us?

[18:50] <daveake_> R1 seems rather high to me
[18:51] <eroomde> lol yes
[18:51] <daveake_> R2 ditto
[18:51] <eroomde> all everything that needs vcc seem to have a diode preventing them from doing so
[18:51] <daveake_> Also you probably ought to add some caps either side of the regulator
[18:52] <eroomde> also*
[18:52] <Hiena> Ohhh, ST DIscovery looks promising. M4 core, MEMS, magneto sensor and tons of IO.
[18:52] <eroomde> i don't mean vcc i mean 3v3 sorry
[18:52] <Hix> yup, resistors overlooked, now 560Ohm
[18:52] <eroomde> but hix, bigger problem is v-reset and vcc and vcc_io are not connected to 3.3V
[18:52] <Hix> LED polarity wrong way?
[18:53] <eroomde> sure but don;t do it like that anyway
[18:53] <eroomde> connect them directly to 3v3

[21:55] <MrCraig> I'm looking at APRS tracking radios so that I can track a flight in the US (that I'm taking far too long to plan and build). I've found some old kenwood radios on ebay for $65/$70 which is very reasonable, but I was considering the expensive AvMap Geosat 5/6 system and they're tool old to work with it. Does anyone know if there are good cheap APRS tracking options? Can I use one of the older radios wth a laptop like we use dl-fldi
[21:56] <fsphil> any old FM radio will do
[21:56] <fsphil> well any that does the 2m band
[21:56] <fsphil> the baofeng handhelds might do, they're pretty damn cheap

[21:56] <MrCraig> Hi fsphil :-) One of the features I like with the AvMap is that it has a GPS navigation system that'll automatically update each time it gets a location from the payload. I have no idea what software can be used with the cheaper radios
[21:57] <fsphil> how's TX MrCraig?
[21:57] <fsphil> I'm not great on APRS software for windows
[21:57] <fsphil> but I know there are a few options
[21:57] <MrCraig> I'm loving it here in texas :-) and I met someone out here, so I'm looking at making my stay permanent.
[21:58] <fsphil> sweet!
[21:59] <fsphil> you'll miss the weather :p
[21:59] <MrCraig> I got myself membership to the local hackspace (dallas makerce) and just shipped my electronics gear from the UK. Though my gf does leave me with a little less time for my techie hobbies, I wouldn't trade back. :-) I just got some of the same payload boxes shipped from the UK and my chutes - so I'm getting ready to fly.
[22:00] <MrCraig> The weather is awesome too - it's daylight into the evening hours in oct/nov/early december - and blue skys even when it's cold (which is perhaps 6 weeks of the year lol)
[22:00] <fsphil> meh :p
[22:00] <fsphil> I imagine it's a great place to launch from
[22:00] <fsphil> they've quite a bit of land
[22:00] <MrCraig> I was back in England for Christmas - sooo much rain
[22:01] <MrCraig> yeah, and I've made some friends with some land of their own... though I am quite close to two airports, so I have to take care.
[22:02] <MrCraig> Helium is going to be difficult (though not impossible) because the current administration changed the laws and shut down one of the reserves as an outlet (or so I'm told, still researching)
[22:03] <fsphil> At this point I'm basically going to be using H2
[22:03] <fsphil> I've some helium left from my last launch but it's just too expensive
[22:03] <MrCraig> *nods, with the right precautions H2 is fine.
[22:03] <fsphil> definitly
[22:03] <MrCraig> So long as you don't coat your balloon with thermite I'm sure you'll get away with it.
[22:03] <fsphil> I think the key rule is, "don't be stupid"
[22:04] <SP9UOB_Tom> MrCraig: You Can use APRSIS32
[22:04] <MrCraig> Though I did watch a thunderfoot video once on youtube about the amount of energy in H2 and it's a little scarey.
[22:04] <MrCraig> Googling APRSIS32
[22:05] <SP9UOB_Tom> MrCraig: and - of course my awesome APRR modem ;-))) http://sp9uob.verox.pl/dstnc.html <- use googlr translate
[22:06] <fsphil> unless you're mixing it with oxygen in the balloon, I doubt it would do much
[22:06] <fsphil> the big risk is probably the cylinder
[22:06] <fsphil> but that's no different than for helium
[22:06] <MrCraig> fsphil - take water and electrolize it on site.
[22:06] <KF7FER> MrCraig: As usual, I'm a bit late but I use an old Icom IC2AT connected to a TNC-X w/ Bluetooth module. I think display APRS data on a Nexus 7 running APRSdroid
[22:07] <MrCraig> SP9UOB_Tom: I plan on building the transmitter using a HX1 from radiometrix
[22:07] <KF7FER> think=then sorry
[22:07] <MrCraig> KF7FER - I like the android idea - I'm about to pick up a new phone and a tablet - saves the bulky laptop being in the car.
[22:08] <KF7FER> Yup. Plus I can use the Nexus 7 with my Kenwood D710
[22:08] <SP9UOB_Tom> MrCraig: just like mine ;-) ? =>http://sp9uob.verox.pl/IMG_9935-big.JPG
[22:09] <SP9UOB_Tom> note: here in Europe we have 144.800 for APRS
[22:09] <SP9UOB_Tom> http://sp9uob.verox.pl/IMG_9936-big.JPG
[22:10] <MrCraig> That's a sweet board Tom, very professional job.
[22:10] <SP9UOB_Tom> MrCraig: thank You :-)

[22:13] <MrCraig> it's just a connection to the microphone socket right?
[22:13] <KF7FER> MrCraig: Pretty much any radio should work. Kenwoods are what I've used the most. Just need to make a custom cable to connect to the TNC
[22:13] <KF7FER> pretty much - plus you need to hookup transmit if you want to send packets
[22:13] <MrCraig> *nods, I'm only planning on RX from the payload at this point, but it could be interesting to track the car too from a base station.
[22:14] <KF7FER> is pretty trivial to wire up a cable then
[22:15] <MrCraig> I'm sure Radioshack or mouser will have everything I need for that too, and I've found some kit TNC-X -> USB / Bluetooth devices.
[22:16] <MrCraig> This all became much more straight forwards having talked with you guys :)
[22:18] <KF7FER> MrCraig: This is the unit I used http://www.tnc-x.com/bt.htm - I'm sure you could do something cheaper but I didn't bother. Was fast and easy
[22:19] <MrCraig> KF7FER - that's the very one I just found on google and bookmarked :) I'm on the right track then :)
[22:19] <KF7FER> excellent - you sure are. Great product from a good guy
[22:19] <KF7FER> simple and clean

[22:19] <KF7FER> just works
[22:19] <MrCraig> I have a board that still needs to be assembled which is an arduino / ntx-2 setup, but I think the pin-outs for the ntx2 and the hx-1 are the same, so I'm thinking I can assemble it for aprs.
[22:20] <KF7FER> just be careful about the NTx2 - I just learned today that many designs for the NTX2 tie EN high and you don't want that for the HX1
[22:20] <KF7FER> EN on the HX1 is basically PTT
[22:21] <MrCraig> thanks, I'll watch for that.
[22:21] <KF7FER> well duh - it's the same on the NTX2 but the typical designs seem to always transmit

[22:22] <MrCraig> Yes - I was constantly tx'ing with my last setup too.
[22:23] <MrCraig> It's hard to believe it's been almost 2 years since I did a hab, and that was my first and only flight. Life sometimes gets in the way.
[22:24] <KF7FER> no doubt. Me too.
[22:24] <KF7FER> hopefully I'm going to do another late Spring
[22:25] <MrCraig> I was hoping to get one in months ago, but had many problems getting components together.
[22:25] <MrCraig> I'm now aiming for a.s.a.p
[22:25] <KF7FER> where are you located?
[22:25] <MrCraig> I relocated to Dallas Texas 6 months ago, from the midlands in England.
[22:26] <KF7FER> quite a change then?
[22:26] <KF7FER> I've only been to Austin and I thought it was real... brown. Kinda ugly
[22:27] <MrCraig> yeah, a bit :) I moved for work, which has also been insanely busy. I visited Austin the first few weeks I was here, in July (>100 degree heat) - both Austin and Dallas are brown a lot of the time.
[22:28] <fsphil> it does seem that way from all the pictures I've seen
[22:29] <Lunar_Lander> btw did you hear the space news?
[22:29] <fsphil> you can't hear things in space Lunar_Lander
[22:29] <KF7FER> even if they scream
[22:29] <Lunar_Lander> yea
[22:29] <fsphil> especially if they scream
[22:29] <Lunar_Lander> yea
[22:29] <Lunar_Lander> anyway
[22:29] <Lunar_Lander> Japan will launch the Hayabusa 2 probe in 2014 or 2015
[22:29] <Lunar_Lander> India will launch a Orbiter to Mars
[22:30] <Lunar_Lander> and China will try to land a rover on the moon

[22:53] <Hix> sorry Upu, wasn't on the ball there. jst a quickie
[22:54] <Upu> nps
[22:54] <Hix> the notch for the sarantel on the pcb. how do you spec that
[22:54] <Upu> just use the part in ava.lbr
[22:54] <Hix> or does mitch take it from the lib outline
[22:54] <daveake_> fsphil indeed
[22:54] <Upu> Seeed and Mitch's fabs put the notch in
[22:54] <Upu> Olimex never did
[22:55] <Hix> ok cool, was arsing around with layers and getting nowhere.
[22:57] <Upu> chuck me the eagle files when you're done I'll have a scan over them
[23:00] <Hix> cool thx, heres a brief outline of whats cooking. Plan is jumpers enabling switching between software and proper serial for dev work. with jumpers from arduino for all eventualities. I'm pleased with my first effort, so far. http://i.imgur.com/vcL9M.png
[23:01] <Upu> don't want to pee on your bonfire but the track from the GPS to the antenna is far too long an convoluted
[23:02] <nigelvh> Yeah, at 1.5GHz that's going to be an issue
[23:02] <Upu> ideally it should be a short straight line
[23:03] <Upu> sorry to be about as subtle as a brick but best you find out now before you've splashed the money on the PCB's
[23:03] <Randomskk> the output from the ntx2 is a bit suspect too
[23:03] cuddykid (~acudworth@92.40.254.10.threembb.co.uk) left irc: Remote host closed the connection
[23:03] <Randomskk> and having the RX output from the NTX2 to so close to the GPS is definitely a bad idea
[23:03] <Hix> no probs, bring the constructive critics
[23:03] cuddykid (~acudworth@92.40.254.10.threembb.co.uk) joined #highaltitude.
[23:04] <Upu> ok what Randomskk said
[23:04] <Upu> use a SMD regulator
[23:04] <Upu> will save heaps of space
[23:04] <Randomskk> try to have the GPS antenna and chip at one end of the shield and the NTX2's output at the other end
[23:04] <Upu> and you don't need 2A
[23:04] <Randomskk> and maybe use an SMA connector for the radio output
[23:04] <Randomskk> rather than a two pin header
[23:04] <Upu> ---------------/\
[23:04] <Upu> that
[23:04] <nigelvh> Definitely
[23:04] <Hix> gonna change that just need lib part
[23:05] <Upu> I'd lay the NTX2 flat as well
[23:05] <Upu> but thats just me
[23:05] <Randomskk> aesthetic thing but avoid non-45-degree tracks too. you mostly have and then you've got this one that isn't
[23:05] <Randomskk> circular vias are a bit nicer than square ones
[23:05] <Hix> but after hours I had a break from CAD after 60 hours of CAD this week at work :p
[23:05] <Hix> yeah, how to change vias?
[23:06] <Upu> right click on them properties
[23:06] <Upu> you can select it under there
[23:06] <Hix> did have a thought rgd ntx2 - wires and remote in insulations to save shift shit
[23:06] <Hix> k cool
[23:07] <Upu> istr the NTX will fix between the pins on a Arduino
[23:07] <Upu> horizontally if you know what I mean
[23:08] <Hix> hmm , got a broken pin so its tricky
[23:08] <Upu> give me 2 mins
[23:09] <Hix> all good feedback, better now than later, unlike work where i design a part and it goes through 2 reviews only to be picked up by someone as its being made [we need to save some weight, cost, face]
[23:11] <Upu> http://i.imgur.com/xcNv0.png
[23:11] <Upu> something like that
[23:11] <nigelvh> Yes, that would be much better for RF.
[23:12] <Upu> if you're making a shield I'd probably use an active antenna for the GPS too
[23:12] <Upu> and you will need level conversion between the GPS 3.3V and the Arduino 5V
[23:13] <Hix> oh, semed to accept it earlier. maybe just luck
[23:14] <Hix> why active?
[23:14] <Upu> you can screw an antenna on to the board via an SMA will be more robust than having that Sarantel sticking out of the edge of the board
[23:14] <Upu> also, its probably not an issue, but that antenna is EoL
[23:15] <Upu> They are still availble though
[23:15] <Hix> using what i have in th ebin
[23:15] <Hix> the bin
[23:15] <Hix> for now, testing only
[23:15] <Upu> yeah I wouldn't worry about it
[23:15] <Hix> k
[23:15] <Upu> I can still get them

[23:16] <Hix> tbh its a bit worse for wear so it'll do 4 now
