[11:18] <fsphil> that is bad daveake
[11:21] <Upu> afternoon all
[11:21] <Upu> hi en4rab
[11:21] <en4rab> have you all seen the hack to turn a £15 realtek 2832U based USB DVB stick into a software defined radio, i thought it might be of interest to you as a cheap radio for tracking
[11:21] <Upu> Yup it think a number of people are working with them now
[11:22] <Upu> don't worry we didn't miss it :)
[11:22] <en4rab> i tried tracking a flight a week or so ago but i dont have a decent antenna
[11:22] <Darkside> oh thats a point, i need to get the preamp boards sent off
[11:22] <Upu> yeah
[11:22] <Darkside> fff
[11:22] <Darkside> ok
[11:22] <Darkside> will do it tonight
[11:22] Action: Upu poke
[11:23] <Upu> not that we care we're all on holiday over here Darkside
[11:23] <Darkside> ahh crap the guy isnt online
[11:23] <Darkside> heh
[11:26] <fsphil> yay holidays
[11:27] <en4rab> If any of you are messing with the dvb dongles this software is a promising alternative to HDSDR http://sdrsharp.com/ the Dev (continuous integration) builds have builtin support for the RTL dongles

[11:58] <fsphil> ah sweet, gqrx works
[11:58] <jonsowman> fsphil: cool :D
[11:59] <fsphil> and it doesn't suck!
[11:59] <jonsowman> haha
[11:59] <jonsowman> its beena while since i've tried it
[11:59] <jonsowman> don't know how much has changed
[12:01] <fsphil> it's much nicer than spectravue
[12:02] <Darkside> theres a fork that works with the RTL dongles
[12:02] <Darkside> Upu: i've requested a quote for the filter/preamp pcbs
[12:04] <joph> http://sprut.de/electronic/pic/projekte/adsb/adsb_en.html <<< nice
[12:06] <Darkside> haha i've actually built one of those
[12:06] <Darkside> well, the miniadsb part of it
[12:06] <Darkside> a friend of mine is doing the pic side of it
[12:07] <joph> the miniadsb is very expensive
[12:07] <joph> 10 parts and then 50¬?
[12:07] <joph> may an antenna with a RTL dongle will also work
[12:08] <fsphil> I can't tune the fcd from within gqrx, have to use qthid
[12:08] <Darkside> joph: this doesn't require a pc though
[12:08] <Darkside> it can all be done in a micro
[12:08] <joph> that's true
[12:08] <Darkside> but yes, its quite expensive
[12:08] <Darkside> probably because of the PCB
[12:08] <joph> i think so
[12:09] <joph> cause it looks like homemade pcb and no commercial dealer for the pcb
[12:09] <Darkside> its not homemade
[12:09] <joph> the PCB just costs 6¬
[12:09] <Darkside> its properly manufactured
[12:10] <joph> 6¬ is okay, may i'll order one
[12:10] <Darkside> hopefully you can find the other components
[12:10] <Darkside> the ADS-B SAW filter is probably the hardest to find i think
[12:10] <joph> 5¬ shipping, he could send it in a letter...
[12:11] <joph> wow, no TA1090EC on ebay
[12:12] <Darkside> well its the standard saw filter footprint

[12:12] <Darkside> but i wouldn't expet them to be that easy to get hold of
[12:12] <joph> even nothing on alibaba
[12:13] <Darkside> yeah i think this is the problem
[12:14] <Darkside> that saw filter is likely the expensive component
[12:15] gonzo_mob (~gonzo_mob@213.205.232.223) left irc: Ping timeout: 240 seconds
[12:15] <Darkside> oh wow ok it has 2 saw filers on it
[12:15] <Darkside> yeah ok, thats where the cost comes from
[12:15] <joph> may he orderd 100pcs from the manufactor ;)
[12:15] <Darkside> i bet those aren't cheap

[12:17] <en4rab> in theory at least the realtek dvb sticks could do ads-b, but they are a bit iffy getting them to tune to 1090Mhz
[12:18] <Darkside> they won't be very sensitive either
[12:18] <Darkside> putting a SAW filter + LNA in front would help again
[12:19] <r2x0t> for proper ADS-B decoding you need to oversample little bit, so you can decode overlapping bursts
[12:19] <r2x0t> RTL dongle will for non-overlapping bursts that are very strong
[12:19] <joph> it's also possible to use an receiver circuit from a sat receiver
[12:19] <r2x0t> probably comparable with this ADS-B PIC project if you add filter and preamplifier
[12:19] <joph> i'll try this
[12:20] <fsphil> was there an fcd firmware update? I updated qthid and now it won't detect the dongle
[12:20] <Darkside> i'm on something j
[12:20] <r2x0t> there's FPGA based ADS-B receiver board that's much better
[12:21] <joph> nice
[12:21] <en4rab> if you want to throw fpga's at it then ettus research is the place to start looking

[12:43] <fsphil> yay it's in a library
[12:43] <jonsowman> it could be the call to that library
[12:43] <jonsowman> i.e. gqrx is calling that method when it shouldn't be
[12:43] <jonsowman> but that method is doing something which then segfaults
[12:44] <fsphil> libusb_submit_transfer(dev->transfer);
[12:44] <fsphil> I think there's a race condition going on
[12:44] <Lunar_Lander_> does anyone of you use Twitter too?

[13:21] <Lunar_Lander_> what do you mean?
[13:21] <fsphil> a heisenbug is a bug or crash that disappears as soon as you start looking for the cause
[13:22] <Lunar_Lander_> ah
[13:23] <fsphil> I've added fprintf's to watch the order things are called, but now it doesn't crash
[13:23] <Lunar_Lander_> ah
[13:23] <Lunar_Lander_> what's fprintf exactly?
[13:24] <fsphil> prints a message to the console
[13:24] <Lunar_Lander_> ah you write it in the terminal?
[13:24] <fsphil> exactly
[13:25] <Lunar_Lander_> and what happens if you do that command?
[13:26] <fsphil> just prints a message
[13:27] <r2x0t> fprintf outputs formatted string to file handle, printf is equal to fprintf(stdout,something_here...)
[13:27] <Lunar_Lander_> ah
[13:28] <r2x0t> stdout and stderr are pseudohandles you can use
[13:28] <r2x0t> or open output files using FILE *f = fopen("blah.txt","wt"); fprintf(f,"doh!"); fclose(f);

[13:44] <Lunar_Lander_> hey Upu
[13:45] <Lunar_Lander_> Upu, your GPS with sarantel antenna is amazing
[13:45] <Lunar_Lander_> I thought I told you how I got lock in 20 seconds and in the styrofoam box it took about 30 seconds
[13:47] <Upu> thats quite quick
[13:47] <Upu> thin roof ? :)
[13:47] <Lunar_Lander_> XD yea the box had a thin lid
[13:48] <Lunar_Lander_> on the first try I had the breadboard placed on some metal grid chair that they have in front of the physics dept.
[13:48] <Upu> glad its working anyway
[13:48] <Lunar_Lander_> so clear sky view
[13:48] <Lunar_Lander_> yeah
[13:48] <Upu> when you launchign ?
[13:48] <Lunar_Lander_> this summer hopefully, I'm currently on the GPS code, later I'll try if I can read the GPS via the arduino
[13:49] <Lunar_Lander_> and I got a canon A490 as suggested by daveake
[13:49] <Upu> Just finishing a Wiki page on connecting GPS to Arduino
[13:49] <Upu> http://ava.upuaut.net/store/wiki/doku.php?id=levelconvertor
[13:49] <Upu> might help
[13:49] <Upu> its meant for a new board I have for the shop
[13:51] <Lunar_Lander_> ah
[13:51] <Lunar_Lander_> voltage div?
[13:51] <Upu> and a regulator

[13:52] <Upu> http://ava.upuaut.net/store/index.php?route=product/product&path=59_60&product_id=68
[13:52] <Lunar_Lander_> voltage div does not really apply as I got the 3.3V arduino
[13:52] <Upu> oh in that case you don't need this one
[13:53] <Lunar_Lander_> yeah
[13:53] <Lunar_Lander_> oh and I got a mega, so I try my luck connecting it to UART 1
[13:53] <Lunar_Lander_> as I learned that UART 0 is occupied when code is uploaded

[17:11] <MrScienceMan> hello
[17:12] <jdtanner> I've got a wee Ublox question if anyone is about? I'm looking at existing code to set the airborne mode and the following seems to be being used:
[17:12] <jdtanner> uint8_t setNav[] = {0xB5, 0x62, 0x06, 0x24, 0x24, 0x00, 0xFF, 0xFF, 0x06, 0x03, 0x00, 0x00, 0x00, 0x00, 0x10, 0x27, 0x00, 0x00, 0x05, 0x00, 0xFA, 0x00, 0xFA, 0x00, 0x64, 0x00, 0x2C, 0x01, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x16, 0xDC};
[17:12] <jdtanner> I've tried to get my head around where that has come from (with reference to the Ublox docs) but I think I need a hint& :/
[17:13] <jonsowman> where did that come from?
[17:13] <jonsowman> you don't need to set the entire message
[17:13] <jonsowman> since you can mask off the bits you dont want to change
[17:13] <jdtanner> It has come from quite a few places& but here is one http://ukhas.org.uk/projects:picoatlas:picoatlasi
[17:14] <jonsowman> okay
[17:14] <jonsowman> well it should work
[17:14] <jonsowman> basically you have 2 sync bytes
[17:14] <jonsowman> then 2 command bytes
[17:14] <jonsowman> then 2 length bytes
[17:15] <jonsowman> then variable length message
[17:15] <jonsowman> then 2 checksum bytes
[17:16] <jdtanner> ok
[17:16] <jonsowman> you want the ublox protocol spec sheet
[17:16] <MrScienceMan> http://ukhas.org.uk/guides:falcom_fsa03
[17:16] <jonsowman> which is excellent bedtime reading
[17:16] <MrScienceMan> there are some command on here
[17:17] <jdtanner> Yeah, I'm trying to get my head around the ublox protocol :/
[17:17] <jonsowman> it's actually very simple (the above frame format)
[17:17] <jonsowman> but there are /so many/ different messages
[17:17] <jdtanner> that is the problem I'm having&trying to figure out the message to send
[17:18] <jonsowman> search the spec sheet for the command bytes
[17:18] <jonsowman> 0x06 0x24
[17:19] <jdtanner> yeah, got it&seems like french ;)

[18:40] <fsphil> not sure that you should

[18:41] <Lunar_Lander> a tube radio?
[18:41] <fsphil> aah good old Jack
[18:42] <Astrobiol> Yes, valves seem a bit of a waste for 10mw. But any of advantage for other frequencies? I know some people have been trying HF for instance
[18:42] <fsphil> valves don't have any advantage over transistors
[18:42] <fsphil> (well I hear they're better at handling mismatched loads)
[18:42] <Astrobiol> Strictly just for fun :-)
[18:43] <fsphil> can you even buy valves?
[18:43] <Laurenceb_> http://www.b3tards.com/u/037e58b9e054b3c8dd7b/queenjubilee_01.jpg
[18:44] <Astrobiol> Yes you can, and in fact I know a guy at UCL who stumbled across an ancient storeroom full of them. They're also in demand for high-end amps etc
[18:44] <fsphil> aah audiophiles
[18:44] <daveake> Well they'd keep the payload warm
[18:45] <fsphil> would give the signal a warmer sound
[18:46] <fsphil> I guess an AM transmitter would be easy to make with them
[18:46] <Astrobiol> I just feel that I am at some fundamental useless at microelectronics (PC104 misadventures etc) and so perhaps I should go the other direction for the vintage look?
[18:46] <Lunar_Lander> one sec please
[18:46] <daveake> Yeah audiophiles ... the type of person who buys a $485 wooden knob - http://boingboing.net/2005/11/07/astronomically-overp.html
[18:47] <Lunar_Lander> when you want to reference someone on Twitter do you like write #CUSpaceflight or so?
[18:47] <fsphil> PC104 is pretty vintage itself
[18:48] <daveake> PC104 --> valves. Well one day the random jumps will land on something workable
[18:48] <fsphil> just use an arduino, they work almost all the time :)
[18:48] <Lunar_Lander> fsphil, btw BTTF III reference!
[18:48] <Lunar_Lander> where doc repairs the time circuits with the tubes
[18:48] <Lunar_Lander> xD
[18:49] <Lunar_Lander> that thing on the front hood
[18:49] <fsphil> hah
[18:49] <Astrobiol> Exactly fsphil :-) but still used quite a lot. One of the smallest (pre-Pi?) footprints for a complete computer. Also quite a simple bus - typically just a couple of bytes for each board in the stack. Recently some heavily armoured stacks have been made
[18:50] <fsphil> depends what you're doing I guess, but for almost everthing I'd ever consider flying a simple avr-based system works well. the Pi will probably get flown too :)
[18:51] <fsphil> although I'll wait until they're a bit more available, don't want to loose this one in the ocean just yet
[18:51] <Astrobiol> Gotta go, just roasting my supper on some dusty UCL valves

After that, it listens to dl-fldigi and habitat and it adds any payloads it receives. If those get higher than the ones in the table, then it will show them in their correct positions
[19:28] <daveake> I just need to add "if (Payload <> "XABEN") then ... :p
[19:28] <Lunar_Lander> yeah
[19:28] <Lunar_Lander> cool!

[19:29] <daveake> LL That was a joke ... Steve keeps beating my records with his XABEN flights!
[19:30] <Lunar_Lander> xD sorry didn't understand that joke
[19:31] <Lunar_Lander> cause I didn't pay attention to the "I just need to add..."
[19:32] <daveake> if (Payload = XABEN) Altitude-=1000

[19:35] <fsphil> right, I better try break..er, soldering this 644p
[19:39] <Lunar_Lander> xD
[19:39] <Lunar_Lander> ah ok daveake XD
[20:23] <Laurenceb_> anyone here used parcelforce?
[20:23] <Laurenceb_> some weird stuff is happening with my parcel
[20:23] <Laurenceb_> its said "In progress " for a week now
[20:25] <daveake> parcelfarce? Not the best ...
[20:25] <Laurenceb_> now all the trracking details have vanished
[20:25] <Laurenceb_> very odd
[20:25] <daveake> Mind you, I had a TNT parcel end up in the wrong country

[20:30] <Lunar_Lander> fsphil, daveake it is him!
[20:30] <Laurenceb_> service has changed to Express 24
[20:30] <SpeedEvil> Parcelforce recently sent a solar panel from birmingham to Fife via the Isle of wight.
[20:30] <SpeedEvil> For me.
[20:31] <Laurenceb_> maybe its going to be delivered i tuesday
[20:31] <Lunar_Lander> that is like
[20:31] <Laurenceb_> *on
[20:31] <Laurenceb_> some chance
[20:31] <Lunar_Lander> too much extra way?

[21:50] <jonsowman> yeah don't worry about it too much jdtanner
[21:51] <jonsowman> you can grab the commands from ucenter as daveake said
[21:52] <Upu> yeah basically you issue them via u-Center
[21:52] <Upu> and watch the logs
[21:52] <Upu> but kindly jcoxon has listed them all out
[21:52] <jdtanner> I was on a mission to figure this all out from scratch&haha&should have installed u-center :)
[21:52] <Lunar_Lander> XD
[21:52] <Lunar_Lander> oh damn
[21:52] <Upu> oh yeah install u-Center
[21:52] <jdtanner> &if they did a Mac version :/
[21:52] <Lunar_Lander> now it is 7 minutes to midnight
[21:53] <Upu> http://www.u-blox.com/en/evaluation-tools-a-software/u-center/u-center.html
[21:53] <Lunar_Lander> and I still did not test the new code
[21:53] <jonsowman> it's not impossible to do it all from scratch, i had to go through it all for doing the ublox binary protocol
[21:53] <Upu> but you don't need too
[21:53] <Upu> Example codes : http://ukhas.org.uk/guides:ublox6
[21:53] <Upu> http://ukhas.org.uk/guides:falcom_fsa03#common_ubx_commands_decoded_directly_from_u-center

[21:54] <Lunar_Lander> just a question Upu
[21:54] <Lunar_Lander> the new board with regulator can be powered by an arduino?
[21:54] <jdtanner> Yep, been working from those ;) I missed the "&decoded directly from u-center" :D
[21:54] <Upu> yes
[21:54] <Upu> @ Lunar_Lander
[21:55] <Lunar_Lander> but the "old" one doesn't?
[21:55] <jdtanner> thanks all...
[21:55] <Upu> the new one runs from the 5V supply on the Arduino which can do more than 50mA
[21:55] <jdtanner> This beer tally is starting to get quite large
[21:56] <Lunar_Lander> ah
[21:56] <Lunar_Lander> hm
[21:56] <Lunar_Lander> the 3.3V pin is limited to 50 mA, cause there is a second regulator in the arduino I assume?
[21:56] <fsphil> I used the u-center packets as a base, then tweaked the values I needed to
[21:56] <fsphil> ignore the rest
[21:56] <Lunar_Lander> but say
[21:57] <Lunar_Lander> the thing with "set ublox to airborne"

[21:57] <Lunar_Lander> is that OK to use the hex values given there in the examples or is tweaking needed?
[21:57] <fsphil> if the existing data does what you need it to do, then you can use it as is
[21:57] <fsphil> I think the bits i was looking at where for power control

[21:59] <Lunar_Lander> got a question still
[21:59] <Lunar_Lander> when someone uses Twitter and the bot here like posts the tweet, how comes that the tweet comes up several times from different people?
[22:00] <Lunar_Lander> can the twitter be connected to the channel?
[22:00] <fsphil> that's people retweeting it
[22:02] <Lunar_Lander> ah
[22:02] <Lunar_Lander> I think it's not a good idea to connect my twitter to here otherwise you'd be bothered with the posts in german to my TV crictics friends
[22:02] <Lunar_Lander> xD
[22:03] <fsphil> the bot only relays messages with certain hash tags
[22:03] <Lunar_Lander> ah
[22:03] <Lunar_Lander> like #UKHAS?
[22:03] <fsphil> yea
