[00:37] <fsphil> nothing wrong with taking thigns slowly
[00:38] <fsphil> unless there's a fire and you're calling the fire brigade
[00:38] <m0psi> y, need to get this right
[00:39] <m0psi> next step is to merge this tx_string constructor with live gps data, and then push out some electrons in rtty formation
[00:39] <m0psi> both of the latter have already been tested individually
[00:39] <m0psi> so, getting close to a tracker!!
[00:40] <m0psi> quite exciting actually

[00:40] <fsphil> yea I enjoyed this bit
[00:42] <Lunar_Lander> hi there
[00:43] <m0psi> hey
[00:43] <fsphil> hmm.. not sure this is correct, http://i.imgur.com/v3FOS.png
[00:43] <m0psi> :-)
[00:43] <m0psi> you playing with an emulator?
[00:43] <fsphil> made one
[00:44] <m0psi> or making one?
[00:44] <m0psi> nice
[00:44] <m0psi> you bored? :-)
[00:44] <fsphil> well, 6510 only.
[00:44] <fsphil> it's too hot outside :)
[00:44] <m0psi> i bought a dragon32 when new
[00:45] <m0psi> they ran out of zxspectrums
[00:45] <m0psi> so, got a dragon instead
[00:45] <fsphil> never seen the dragons
[00:45] <m0psi> crap computer
[00:45] <m0psi> made by matel
[00:45] <fsphil> everyone here had c64's and spectrums
[00:45] <m0psi> look it up
[00:45] <fsphil> and the odd atari
[00:45] <m0psi> right,
[00:45] <m0psi> so, got rid of the dragon, and got a beeb
[00:45] <m0psi> best thing i ever did
[00:45] <m0psi> loved it
[00:46] <Lunar_Lander> fsphil, was that how a C64 looked like when you switched it on?
[00:46] <m0psi> pretty much
[00:46] <fsphil> the real 64 had a blue screen
[00:46] <m0psi> then you got the:
[00:46] <Lunar_Lander> ah
[00:46] <m0psi> >
[00:46] <m0psi> well, the beeb did
[00:46] <Lunar_Lander> I am just reading "Thrust" by Richard Noble
[00:46] <fsphil> http://www.c64-wiki.com/images/c/c9/Einschaltmeldung_C64.jpg
[00:46] <Lunar_Lander> and I got forward to TrustSSC
[00:47] <Lunar_Lander> *ThrustSSC
[00:47] <Lunar_Lander> and there is a photo of testing in 1995 and they have a very old looking grey laptop there
[00:47] <m0psi> then of course, you typed: 10 print "hello", 20 goto 10
[00:47] <fsphil> yay infinite loops
[00:47] <m0psi> could watch it for hours!
[00:47] <m0psi> then got bored
[00:48] <Lunar_Lander> yea
[00:48] <fsphil> C64's basic was really crude
[00:48] <m0psi> when i got my zx81, i actually tried to write a bot
[00:48] <m0psi> crazy!
[00:48] <m0psi> 1k
[00:48] <m0psi> not a clever one, just a load of if/then
[00:49] <fsphil> it only had 1k ram?
[00:49] <m0psi> but ok for a 12 year old
[00:49] <m0psi> yep
[00:49] <m0psi> some guys had the 16k "Mega Pack"
[00:49] <m0psi> check them out!

[00:50] <fsphil> I wrote a pong game, that was about the only intresting thing I did on the c64
[00:50] <m0psi> i actually had a go writing a flightsim for tie fighters on the dragon 32
[00:50] <m0psi> realised the futility very quick
[00:50] <fsphil> nice
[00:51] <m0psi> ah well. moving back to arduino ....
[00:51] <fsphil> a more powerful machine
[00:51] <m0psi> indeed
[00:51] <fsphil> although much less RAM which is annoying
[00:52] <m0psi> 328k == 328 x more than 1k
[00:52] <fsphil> arduino only has about 1k
[00:53] <m0psi> ?!
[00:53] <fsphil> 1024 bytes of sram :)
[00:53] <m0psi> so, what is 328k?
[00:53] <fsphil> the AVR model
[00:54] <fsphil> sorry, the atmega328 has 2k sram
[00:54] <m0psi> still not following
[00:54] <m0psi> i thought 328 is 328k
[00:54] <m0psi> right?
[00:54] <Lunar_Lander> here is the laptop from ThrustSSC http://s.gullipics.com/image/7/m/0/5yvmef-jg2cxd-llen/IMG6248.jpeg
[00:54] <fsphil> nope, just the model of the AVR chip
[00:54] <m0psi> oh
[00:55] <fsphil> no AVR has more than 8k iirc
[00:55] <m0psi> i see
[00:55] <m0psi> so, confused now
[00:56] <m0psi> the compiler says sketch size 7,180 bytes of 32,256 max
[00:56] <m0psi> what is that about then?
[00:56] RG_LZ1DE1 (~lz1dev@ left irc: Ping timeout: 244 seconds
[00:56] <fsphil> program size
[00:56] <m0psi> but that has to live in ram, right?
[00:56] <fsphil> it has 32kb of space for program
[00:57] <fsphil> nope, that lives on flrash
[00:57] <fsphil> flash
[00:57] <m0psi> ah
[00:57] <m0psi> so, flash + ram
[00:57] <fsphil> exactly
[00:57] <fsphil> there's also eeprom, 1k in the 328
[00:57] <m0psi> ok, so, 328 is related to flash?
[00:57] <fsphil> 328 is simply the model number
[00:57] <m0psi> ok
[00:58] <m0psi> so, how can i know the flash size?
[00:58] <fsphil> it'll be in the specs for your board
[00:58] <fsphil> that and it says 32,256 max above :)
[00:58] <m0psi> ok, so what's the story with eeprom?
[00:58] <m0psi> (got that bit :-) )
[00:59] <fsphil> eeprom is memory that retains its contents without power
[00:59] <fsphil> like flash, but writeable
[00:59] <fsphil> you'd use it to store settings for example
[00:59] <m0psi> but i thought that once you upload a program, it is stored forever
[01:00] <fsphil> yes, but you can't normally write to flash from your program
[01:00] <fsphil> only the bootloader or external programmer can do that
[01:00] <m0psi> oh
[01:00] <m0psi> so, eeprom can write to flash
[01:00] <m0psi> and you run from flash
[01:00] <m0psi> using ram, as the execution place
[01:01] <fsphil> the program can only ever be stored and executed from flash
[01:01] <fsphil> the cpu reads it from flash directly
[01:02] <m0psi> ok, so the flash write to eeprom, to store stuff, as a sketchpad
[01:02] <fsphil> your program can write to eeprom
[01:02] <m0psi> as a nonvolitile mem
[01:02] <fsphil> yep
[01:02] <m0psi> ok, like a permanent logging place
[01:02] <m0psi> that can tolerate power losss
[01:02] <fsphil> the cpu can't execute anything from sram or eeprom, they're only used for data
[01:03] <m0psi> ok, i get the picture
[01:03] <m0psi> so, if i stored my gps data in eeprom, and recovered the tracker afterpower loss, i can then power it up, to read its log
[01:04] <fsphil> in theory yep
[01:04] <m0psi> interesting
[01:04] <m0psi> clever these japanese aren't they
[01:04] <m0psi> well, italians :-)
[01:04] <fsphil> I'm considering doing that with a backup tracker
[01:05] <arko> anyone here know a low cost method to simulating hab conditions (-60c/1mbar)
[01:05] <fsphil> atmel make the avr, bot actually sure where they're based
[01:05] <m0psi> y, you can leave it in the corner just quietly logging stuff
[01:05] <fsphil> an, american
[01:05] <m0psi> liq N2 ?
[01:05] <fsphil> seems if you need more memory, the arm chips are the way to go
[01:06] <m0psi> is at 77K
[01:06] <m0psi> arm chip itself has the mem? or the infrastructure around it?
[01:06] <fsphil> I saw someone using a fire extinguisher and a sock to cool a payload down
[01:06] <fsphil> I think that might have been steve?
[01:07] <m0psi> fire ext is CO2 i think
[01:07] <fsphil> some have memory, some don't
[01:07] <fsphil> it's the rapid decompression that cools it
[01:07] <fsphil> then they put it in dry ice
[01:07] <m0psi> i was aksing the same question a few days ago, and asked for dry ice
[01:07] <fsphil> in an insulated box
[01:08] <m0psi> dry ice is cheap from lab supplies
[01:08] <m0psi> liq N2 is complicated to store and handle, unless you have a good dewer
[01:08] <m0psi> in fact, some chemicals get delivered in a polystrn box, in dry ice
[01:08] <fsphil> doing the atmospheric pressure would be a lot trickier
[01:09] <fsphil> to be honest the simplest way of testing is to launch it :)
[01:09] <m0psi> y, some kind of plunger
[01:09] <fsphil> unless you happen to have a vaccume chamber
[01:09] <m0psi> there are plenty of low cost vac pumps for that kind of pressure
[01:09] <fsphil> -e
[01:10] <fsphil> temperature seems to be the big thing, the low pressure actually helps keep things a bit warmer
[01:10] <m0psi> i used to use vac pumps that really are looking to get the last few atoms out
[01:10] <m0psi> takes forever!
[01:10] <m0psi> why?
[01:10] <m0psi> why does low P keep things warm?
[01:10] <fsphil> less air to transfer heat away from components
[01:11] <m0psi> instulator?
[01:11] <m0psi> right
[01:11] <m0psi> well, i better get on with this code, it is not self writing yet!

[04:46] <mrShrimp> erm, I have question
[04:46] <mrShrimp> The GPS unit I purchased is outputting NMEA packets
[04:46] <mrShrimp> that say that it does not have a fix
[04:46] <mrShrimp> yet when I plug in recorded data to VisualGPS
[04:46] <Darkside> which gps unit?
[04:47] <mrShrimp> Trimble Copernicus II
[04:47] <Darkside> k
[04:47] <mrShrimp> When I plug in data to VisualGPS it outputs exact coordinates
[04:47] <mrShrimp> even though I can't seem to find where it is getting them from
[04:47] <Darkside> no idea
[04:47] <Darkside> i'd truyst the data from the gps diretly
[04:47] <Darkside> it might be reporting a position, but have no fix
[04:48] <mrShrimp> where would it get that position from?
[04:48] <Darkside> dunno
[04:48] <mrShrimp> well
[04:48] <mrShrimp> it does show latitude and longitude
[04:48] <Darkside> maybe it had a fix for a short time
[04:48] <mrShrimp> but it says there is no fix, and it doesn't display altitude
[04:48] <Darkside> and is reporting the last fix position
[04:48] <mrShrimp> maybe
[04:48] <mrShrimp> I'll check
[04:49] <mrShrimp> wth
[04:50] <mrShrimp> when I plug in the data from the text file for the second time, there is no read.
[04:50] <mrShrimp> I think you are right, it got a fix once or twice only
[04:50] <mrShrimp> in a previous test, and it kept the data from that
[04:51] <mrShrimp> I'm going to mess around with the voltage, maybe it needs to be in the upper range.

[14:33] <x-f> not sure what you mean
[14:34] <Broliv> When configuring the reciever using CFG-NAV5, there is a bit assigned to altitude variation. In the sample code i've got it is set to 1m but in the documentation it is not set by default. I'm just trying to figureout what it is for.
[14:35] <Broliv> if that makes sense?
[14:37] <Broliv> I've had a look online but i've not been able to find anything and the doumentation from ublox only mentions it twice in the whole 220 page document
[14:38] <x-f> i don't know, sorry
[14:38] <Broliv> no worries
[14:38] <Upu> mail me the query through Broliv

[19:04] <costyn> evening
[19:04] <costyn> quick question on NTX2. should bot RF gnd's be connected to ant gnd or only GND2?
[19:05] <eroomde> both
[19:05] <costyn> ok... used only gnd2 last time I think
[19:05] <eroomde> i.e. GND - RF_out - GND
[19:05] <costyn> yes
[19:05] <eroomde> it's nice and easy if it's going to an sma connector
[19:05] trn (~trn@adsl-065-007-181-160.sip.bct.bellsouth.net) joined #highaltitude.
[19:05] <eroomde> as you can just run lines out straight from the 3 pins to the 3 pins on the connector
[19:06] <costyn> yea doing that as we speak :)
[19:06] <eroomde> you don't have to connect the rf gnd to the global gnd though
[19:06] <eroomde> as that's done via the chip
[19:06] <costyn> right
[19:06] <eroomde> and it's probably better to keep it separate to keep the emi down
[19:06] <eroomde> something to bear in mind if you're doing a global copper pour, say
[19:06] <costyn> does global gnd tend to get noisy?
[19:07] <costyn> right
[19:07] <eroomde> other way round really
[19:07] <eroomde> in this case
[19:07] <costyn> ah yea
[19:07] <eroomde> i.e the rf gnd might be a bit noisy
[19:07] <eroomde> but in general it's good to split your ground planes up into separate functional bits
[19:07] <Randomskk> someone asked about this once and I drew this https://randomskk.net/u/rfout.png
[19:07] <eroomde> i.e. all the analog stuff with one bit of ground plane
[19:08] <eroomde> all the digital switching stuff like the uC and spi chip[s in another bit
[19:08] <eroomde> rf in another
[19:08] <eroomde> and all just connect them up at one single point
[19:08] <eroomde> ideally by the power supplky
[19:08] <Randomskk> but if you do split your ground planes, you have to be really really careful about return paths
[19:08] <Randomskk> I mean you should be careful anyway
[19:08] <costyn> eroomde: thanks good to know
[19:08] <eroomde> yes indeed, that's more important
[19:08] <eroomde> so
[19:08] <eroomde> well
[19:09] <Randomskk> but especially with split ground planes, any lines running between sections should go over the join and not the split
[19:09] <Randomskk> lines running over the top of the splits in the ground planes is a bad sign
[19:09] <costyn> Randomskk: can you elaborate about the join vs split?

[19:11] <eroomde> it's almost as exciting as doing muffins

[21:57] <oh7lzb> Over radio?
[21:57] <oh7lzb> Not just over APRS-IS?
[21:57] <RG_LZ1DE1> yes
[21:58] <oh7lzb> How many bytes per picture?
[21:58] <RG_LZ1DE1> well depends
[21:58] <RG_LZ1DE1> 4-10k
[21:58] <RG_LZ1DE1> they will be packetized
[21:59] <Nickolai> hey lunar_lander, yes it's been a while!
[22:00] <oh7lzb> So, about 20 to 50 packets per picture, right?
[22:00] <RG_LZ1DE1> something like that
[22:00] <oh7lzb> RTTY to APRS-IS, or through regular AX.25 APRS igates?
[22:01] <RG_LZ1DE1> regular
[22:01] <RG_LZ1DE1> it seems 160bytes is the limit per packet
[22:01] <Nickolai> eroomde i've been fine, trying to get back into ballooning now, was hoping to get some eagle advice from the forum but looks like we've solved the problem we had
[22:01] <RG_LZ1DE1> if you dont want to break devices
[22:02] <Nickolai> i got together with this group of people here in NYC and we're working on a cubesat, starting with balloons to get some experience
[22:02] <oh7lzb> Mmmyeah, there was some device that you could DOS with a large enough packet?

[22:03] <RG_LZ1DE1> this is what i got form one of the igates
[22:03] <oh7lzb> Other than that, 255 bytes minus APRS packet data encoding (user-defined packet type maybe) should be OK
[22:03] <RG_LZ1DE1> XYXY is the test data
[22:04] <Lunar_Lander> Nickolai, hope you are well :)
[22:04] <oh7lzb> You'll have to do some encoding to avoid some bytes which will be eaten:
[22:04] <oh7lzb> - NUL bytes (there are broken igates which use C string functions which terminate string at NUL)
[22:04] <RG_LZ1DE1> oh7lzb: im working on it ;)
[22:05] <oh7lzb> - DEL byte (eaten by some igate, I don't know which)
[22:05] <Nickolai> hey lunar, yea everything's well, just working on some cubesats now :)
[22:05] <oh7lzb> - Low bytes < 0x20 (well, 0 fits there too)

[22:08] <oh7lzb> Thank you.
[22:08] <RG_LZ1DE1> :D
[22:09] <RG_LZ1DE1> wow 43k
[22:11] <oh7lzb> Those don't count packets which have been mangled by an igate, but which were not *first* received by another non-broken igate.
[22:11] <oh7lzb> So it happens more than that.

[22:41] <Lunar_Lander> yea
[22:41] <Lunar_Lander> I can hear it faintly starting at 0:16
[22:42] <Lunar_Lander> it was the same as with Apex Alpha
[22:42] <Lunar_Lander> when it closed in, dl-fldigi got a better SNR and started decoding
[22:46] <fsphil> you where certainly close enough

[22:51] <Lunar_Lander> actually there has been a LEGO mindstorms HAB flight in Nevada
[22:54] <Lunar_Lander> can I actually load a audio file in dl-fldigi so that it can try to read it?
[22:59] <natrium42> interesting launches in US

[23:04] <fsphil> already checked with fldigi Lunar_Lander, I don't see any rtty either
[23:04] <fsphil> there is a steady tone which might sound a bit like rtty
[23:04] <Lunar_Lander> yea
[23:05] <fsphil> it's *very* easy to hear rtty where there is none. I do it all the time
[23:05] <Lunar_Lander> yea
[23:05] <Lunar_Lander> when I feed this now into dl-fldigi there is one faint line
[23:05] <Lunar_Lander> but only one
[23:05] <fsphil> I'm sure the aircon unit here is doing morse code

[23:16] <Lunar_Lander> if they really flew to the USA and India and so on
[23:19] <eroomde> i don't
[23:19] <Lunar_Lander> yea
[23:19] <Lunar_Lander> I mean the SD cards identified them
[23:21] <natrium42> eroomde: you mean it's plausible?!
[23:22] <Randomskk> I think he means he doesn't wonder.
[23:23] <natrium42> :)
[23:23] <natrium42> wasn't steve involved with that launch?
[23:23] <Lunar_Lander> it was in germany
[23:23] <Lunar_Lander> I don't really think so
