[04:19] <arko> it's actually difficult
[04:19] <nigelvh> I tried it a while ago, but it was still REALLY beta and sorta barely worked.
[04:20] <arko> yeah
[04:20] <arko> it has it's ups and downs
[04:20] <arko> but it's very much improved
[04:20] <arko> ah it looks like there is an eroomde_ in the room though

[04:26] <nigelvh> I actually tend to listen to Country as I'm not orginally from Seattle, but I appreciate the sentiment.
[04:27] <arko> :P
[04:30] <arko> joking aside, how you doing up there?
[04:32] <nigelvh> Doing pretty well. A number of the hams up here are playing with Mesh Networking, so I'm playing with that this evening. Interesting stuff.
[04:32] <eroomde_> arko: no doug
[04:33] <arko> no doug?
[04:33] <eroomde_> has to fly to the uk at the weekend for the week

[04:37] <arko> :)
[04:37] <arko> dont like this internet? make your own internet!
[04:37] <arko> i dig it
[04:38] <nigelvh> Mostly more like "If disaster happens, internet breaks, we have alternate digital communications"
[04:38] <arko> heh
[04:38] <arko> sup irc as a proof of concept
[04:39] <nigelvh> That's something I plan on
[04:39] <nigelvh> also the Asterisk VoIP system is something I'll work on too.

[04:44] <arko_> how cool am i now!?
[04:44] <arko> i totally believe it
[04:45] <arko> hey remember that time we did that thing?
[04:45] <totally_arko> 1/n cools
[04:45] <arko_> of course
[04:45] <arko_> that was awesome
[04:45] <arko> word
[04:45] <totally_arko> Except for the stuff at the place
[04:45] <arko_> oh we dont talk about that
[04:45] <arko> oh right of course
[04:45] <arko_> it's cool, just dont let it happen again
[04:45] <totally_arko> Still can't believe we did that... Not a cool move
[04:45] <arko> np
[04:46] <arko> yeah that was a bad idea
[04:46] <arko_> at least we got that copper tubing and that zebra back
[04:46] <arko> oh yeah, thank heavens
[04:46] <totally_arko> Only to be arrested for riding the zebra through town later.
[04:46] <arko_> wouldn't have done it any other way
[04:47] <arko> wise words
[04:47] <eroomde> i shall typeset that up in latex
[04:47] <eroomde> and frame it
[04:47] Nick change: totally_arko -> nigelvh
[04:48] <arko_> hang it next to your "home sweet home" frame
[04:48] <nigelvh> Good plan. Learn from arko's mistakes
[04:48] <arko_> haha
[04:48] <arko_> eroomde: cool, i get off around around 5:30 or so, i'll pick my gf then you and we can hit the "pub"
[04:49] <arko> hey i haven't died yet
[04:49] <arko_> shut up arko
[04:49] <arko_> the grown ups are talking
[04:49] <nigelvh> Shut up the both of you. Do I need to pull this internet over?!
[04:50] <arko_> hmm
[04:50] <arko_> interesting
[04:50] <arko_> i didnt get the "<nigelvh> [20:49:53] Shut up the both of you. Do I need to pull this internet over?!" in this box
[04:51] <nigelvh> That sounds like your problem.
[04:51] <arko_> yeah
[04:51] <arko_> meh
[04:51] <nigelvh> Perhaps you shouldn't break your internet.
[04:52] <arko_> i really shouldnt
[04:52] <arko_> i should get back to my lab
[04:52] <arko_> eroomde: shoot me details, we can figure out what to do, you tell me what you want to do, I'll drive

[04:53] <arko> ahh
[04:53] <arko> found a cat6 cable
[04:54] <arko> perhaps it's my wifi since my bouncer isn't the one actually dropping
[04:54] <nigelvh> Wifi tends to be less than enterprise grade.
[04:55] <arko_> hmm
[04:55] <arko_> still happening
[04:55] <arko_> must be the bouncer
[04:55] <arko_> i didnt think it would be the internet here
[04:55] <arko_> it's business internet
[04:55] <arko_> and a Ruckus wifi router
[04:55] <arko_> which is fairly enterprise grade :P
[04:56] <nigelvh> Doesn't matter, it's wireless.
[04:56] <arko_> yeah
[04:56] <arko_> not shiny cat6
[04:56] <nigelvh> It's not a replacement for a cable
[04:56] <arko_> right
[04:56] <nigelvh> As for your irc, that's another issue.
[04:56] <arko_> i really should be doing my lab anyway

[10:19] <Cadair> What is the output in?

[10:20] <Cadair> ^What format is the output in?
[10:21] <Darkside> hold on
[10:21] <Darkside> https://github.com/darksidelemm/hf-channel-tools/blob/master/fldigi_quality_plot.py
[10:22] <Darkside> note: that script will peg your cpu
[10:22] <Darkside> as it just graphs as fast as it can
[10:23] <Darkside> so if you load up fldigi and get it demodulating something, that code will show th signal quality in a scrolling plot
[10:23] <Cadair> eek.
[10:23] <Darkside> what i need to do next is work out a way to make it collect data at a regular rate
[10:24] <Darkside> i guess it should really be a separate thread or something
[10:24] <Darkside> but it was a quick hack to see some data over time
[10:28] <Cadair> I can't actually test this as I dont have fldigi
[10:29] <Cadair> https://github.com/Cadair/hf-channel-tools/blob/master/fldigi_quality_plot.py
[10:29] <Darkside> k
[10:29] <Darkside> will tst
[10:30] <Darkside> yeah, that oesnt update
[10:30] <Darkside> doesn't
[10:30] <Cadair> I removed the whole axis redraw so it should be faster. hmmm
[10:31] <Cadair> hang on
[10:32] <Cadair> Your text editor appears to be putting in a tab for indent instead of 4 spaces
[10:32] <Darkside> um
[10:32] <Darkside> yes
[10:32] <Cadair> this just confused me lol
[10:32] <Darkside> whoops
[10:33] <Darkside> convert it to spaces
[10:33] <Darkside> now to figure out what the hell my editor is doing
[10:34] <Cadair> Do you get a figure at all when you run this?!
[10:35] <Darkside> yeah
[10:35] <Cadair> i don't!!
[10:36] <fsphil> interesting, I prefer a tab to spaces
[10:36] <zyp> tabs vs spaces is one of those holy wars
[10:36] <Cadair> PEP8 says spaces.... all hail PEP 8 :S
[10:36] <fsphil> lol

[10:37] <Cadair> I get a static plot if I take out the while loop
[10:37] <Cadair> I have an idea
[10:37] <Cadair> wait for it...
[10:37] <Darkside> start up fldigi?
[10:37] <Darkside> and let it plot zeroes?

[10:38] <Cadair> What size array is current_quality normally?
[10:38] <zyp> Cadair, but PEP 8 is the style guide for the code in the python standard library, not something you have to follow for your own projects
[10:38] <Darkside> Cadair: current_quality is an integer
[10:39] <Darkside> you could test it bu just making current_quality increment on each while loop
[10:39] <Darkside> that way you don't need fldigi
[10:40] <Darkside> what i haven't tested is how long the xmlrpc call takes to execute

[10:52] <Cadair> Using the new matplotlib animation toolkit
[10:53] <Darkside> ooh
[10:53] <Cadair> It will sample the data at whatever rate you set interval=200 to, (in ms)
[10:53] <Darkside> awwwww man
[10:54] <Darkside> AWESOME
[10:54] <Darkside> :-)
[10:54] <Darkside> just be aware that i did fix the axes for a reason
[10:54] <Cadair> I spend a lot of my time using python.
[10:55] <Cadair> Oh yeah, I set it like that because I was using random numbers between 0 and 1000
[10:55] <Cadair> as my data
[10:55] <Cadair> you can just fix it, if you are going to fix them. move it outside the function
[10:55] <Cadair> so do it at the begging
[10:57] <Darkside> k
[10:57] <Cadair> well that was a fun was to burn 40 mins!!
[10:57] <Darkside> :D
[10:57] <Darkside> thanks :D
[10:57] <Cadair> np
[10:57] <Cadair> i have a weakness for python coding problems...
[10:58] <Cadair> zyp, That is true. But i like all my code to be the same. Makes it easier to read.
[10:59] <Cadair> Darkside, What is this for anyway?
[11:00] <Darkside> testing some hf channel simulation software
[11:00] <fsphil> one of the people I work with uses random indentation, if any at all
[11:00] <fsphil> it's horrible
[11:00] <Cadair> fsphil, Punishable by death imo :p
[11:00] <Darkside> i want to look at the SNR over time
[11:00] <Darkside> and the quality output is effectively a filtered and normalised SNR value
[11:00] <Cadair> Fair enough.
[11:01] <Darkside> i wanted this so i could get an idea of whats going on
[11:01] <Cadair> Radio is something I know little about.
[11:01] <Cadair> The animation toolkit is pretty good
[11:01] <Darkside> i'll dump the recorded data to a file too, so i can do plots over time
[11:01] <Darkside> yeah, it looks good
[11:01] <Darkside> i'll be using it in the future
[11:01] <Darkside> the simulator is quite a bit of fun actually
[11:01] <Darkside> i've been writing it for my PhD
[11:01] <Darkside> all in matlab and simulink tho >_>
[11:02] <Cadair> If you ever want to do really fancy things, like update on a new data ping, you can subclass Animation and add a new event_source
[11:02] <Darkside> my next step is to run some data modems through it, so i'm starting to write stuff to automate fldigi
[11:02] <Darkside> the same automation will be useful for some experiments i'm getting set up too - propagation monitoring
[11:03] <Cadair> cool.
[11:03] <Cadair> I was looking a SDR eariler, with a DVB tuner. Think it would be fun to code my own SDR in python... :p
[11:03] <Darkside> go look up quisk

[11:06] <Cadair> whaaaaat do you mean it is 32bit only
[11:07] <Cadair> is this on GH?
[11:07] <Darkside> dont think so
[11:08] <Cadair> :(
[11:08] <Darkside> its a bit shit anyway
[11:08] <Cadair> the world should be on GH lol
[11:08] <Darkside> but yeah, you could do stuff with gnuradio
[11:08] <Cadair> looks like it could be a good starting point
[11:08] <Darkside> mm
[11:08] <Cadair> I quite like the challenge of SDR. In python it would be a fun optimisation problem
[11:08] <Darkside> well, to talk to the RTLSDR stuff you'll need to use gnuradio
[11:09] <Cadair> Is there any specific RTL2832U dongle that is good to get do you know?
[11:11] <Darkside> well, Upu sells them :P
[11:11] <Darkside> i dunno what range they do though
[11:11] <UpuWork> http://ava.upuaut.net/store/index.php?route=product/product&path=71_63&product_id=70
[11:11] <UpuWork> 50Mhz to 1.8Ghz I think
[11:12] <Darkside> i'm sure the FC0013's don't go that high
[11:12] <UpuWork> we had this discussion before they do
[11:12] <UpuWork> Tuner 50MHz to 1700MHz
[11:12] <UpuWork> ok not quite 1.8
[11:12] <Darkside> hmm ok
[11:12] <UpuWork> FC0012 is 1Ghz
[11:12] <Darkside> ahh
[11:13] <UpuWork> R820T is 24-1850
[11:14] <Cadair> 24MHZ?!
[11:14] <Cadair> I need to get me one of these
[11:14] <Darkside> heh
[11:14] <Darkside> they go down quite a way, thts for sure
[11:14] <Cadair> I could do my radio meteor detection project all in software :)
[11:15] <UpuWork> http://www.kickstarter.com/projects/1085541682/bladerf-usb-30-software-defined-radio
[11:15] <Cadair> I like software, I know about it :p
[11:15] <UpuWork> with a down convertor
[11:15] <UpuWork> any SDR can go that down with a down convertor
[11:16] <Cadair> I guess a down converter is something that up-shifts the frequency detected into the receiver?
[11:17] <UpuWork> something like that yeah
[11:18] <Cadair> It makes me sad that kickstarter is $400 to actually get one.
[11:18] <Cadair> but it looks very cool
[11:18] <UpuWork> for what it is its very cheap
[11:18] <Cadair> yes
[11:18] <UpuWork> what are you trying to recieve
[11:18] <UpuWork> ?
[11:19] <Cadair> both a potential future HAB and meteor forward scatter
[11:19] <UpuWork> what frequency is meteor scatter on ?
[11:19] <Cadair> erm I think I was planning on using 50MHz
[11:19] <UpuWork> http://www.funcubedongle.com/?page_id=1073
[11:19] <UpuWork> FUNcube Dongle Pro+
[11:19] <UpuWork> The receiver range is now 150kHz to 240MHz and 420MHz to 1.9GHz.
[11:20] <Cadair> the Ham fixed station thingys (man it is a long time since I have looked into this)
[11:20] <Darkside> only has 192khz receive bandwidthbandwidth
[11:20] <Darkside> but has way better filtering than any RTLSDR
[11:20] <UpuWork> "only"
[11:20] <Darkside> and has much better dynamic range

[11:22] <Cadair> Yeah, I think (at least initally) I will stick to a really really cheap RTLSDR lol
[11:22] <Darkside> it's a good entry point
[11:22] <Cadair> yeah because I am effing broke lol
[11:22] <Darkside> same here
[11:23] <Cadair> SO this: http://ava.upuaut.net/store/index.php?route=product/product&product_id=73
[11:23] <Cadair> is good for HAB monitoring with a RTLSDR?
[11:24] <UpuWork> it works
[11:24] <Darkside> yes
[11:24] <Darkside> it does
[11:24] <Darkside> Cadair: I am VK5QI >_>
[11:24] <UpuWork> though one of Darkside's HABAmps helps
[11:24] <UpuWork> as always depends on your antenna and locations as well
[11:25] <Cadair> Darkside, nice!
[11:26] <Cadair> Is it good enough to be the main receiver?
[11:26] <Cadair> Bearing in mind we have no cash...
[11:26] <Darkside> yeah
[11:26] <Darkside> it uses more CPU though
[11:26] <Darkside> lots more processing
[11:26] <Cadair> Yeah but at receiver we will not be short on some CPU. I will bring my friends whole desktop PC if needed lol
[11:27] <Cadair> I am sure I can run 200W off my car :p
[11:28] <Cadair> Is a standard TV antenna good enough?!
[11:28] <Darkside> no
[11:28] <Cadair> ah damn it
[11:28] <Cadair> but they are so cheap :p
[11:29] <Darkside> for use in the car, make a 1/4 wave monopole magbase
[11:29] <Darkside> you shoul dbe able to get cheap little 70cm magbases on ebay
[11:30] <Cadair> You got a link on how to make one of those by chance?!
[11:30] <Darkside> well
[11:30] <Darkside> not a magbase
[11:30] <Cadair> yeah, I mean the antenna :)
[11:30] <Darkside> its a 1/4 wavelength of wire >_>
[11:30] <Cadair> >.<
[11:30] <Darkside> 16.2cm long
[11:30] <Darkside> or thereabouts
[11:31] <Cadair> cant find a mag mount
[11:31] G8KNN-Jon (~Jon@cpc1-cmbg10-0-0-cust144.5-4.cable.virginmedia.com) left irc: Ping timeout: 248 seconds
[11:32] <Cadair> What freq is it? 435MHz?
[11:32] <Babs> Nice calculation sheet diagram here for antenna length here http://www.w7tck.org/_misc/so-239_ant.html
[11:33] <Darkside> it's going to be 0.235 times the wavelength
[11:33] <Darkside> so not exactly 1/4 wavelength, but close
[11:33] <Darkside> the small difference takes into account the antenna not being infinitely thin
[11:33] <Cadair> Darkside, did you mean something like this? (well the mount part) http://www.ebay.co.uk/itm/VHF-UHF-Taxi-Radio-PMR-Mag-Mount-Antenna-4m-Cable-BNC-138-470Mhz-High-Band-/221179462133?pt=UK_Mobile_Phones_Communication_Radio_Antennas&hash=item337f52c1f5
[11:34] <Darkside> yes
[11:34] <Darkside> you could get that and cut it down
[11:34] <Darkside> maplins sell those
[11:34] <Cadair> yeah
[11:34] <Darkside> in fact, thats exactly what i did when i was in the UK
[11:34] <Darkside> i just went to maplins, got one of those, and cut the whip down
[11:34] <Cadair> Is that going to be good enough?! Seems a bit mad that that will work XD
[11:35] <Darkside> it'll work fine if you're chasing the balloon
[11:36] <Darkside> you may have troubles when you're directly underneath, as the nulls of both transmit and receive antenna radiation patterns will match
[11:36] <Cadair> What's the best kind of antenna rig for a base station?
[11:36] <Darkside> giving less signal
[11:36] <Darkside> depends
[11:36] <Darkside> when its up high, a 1/4 wave would probably work
[11:36] <Darkside> when its at a lowe elevation, you might need a yagi
[11:37] Action: Cadair thinks ..Now based on alt and GPS position, could I make a yagi auto track...
[11:37] <Darkside> yep
[11:38] <Darkside> this has been done
[11:38] <Cadair> I am sure it has
[11:38] <Cadair> use signal strength as a fine tune...
[11:38] <Darkside> i wouldn't bother
[11:38] <Cadair> Now I need a yagi as well
[11:39] <Cadair> But one thing at a time, we need to order the sensors and play with the raspberry pi first.
[11:39] <Darkside> wait
[11:39] <Darkside> rpi >_>
[11:39] <Darkside> you're going to fly a rpi?
[11:39] <Darkside> noooo
[11:39] <Cadair> why?
[11:39] <Darkside> just because daveake did it doesn't mean it's a good idea
[11:40] <Cadair> it's a fantastic idea :p
[11:40] <Darkside> complexity, high power requirements, and not being able to do real-time modulation
[11:40] <Darkside> use an arduino
[11:40] <Darkside> srsly
[11:40] <Cadair> bah
[11:40] <Darkside> srsly
[11:40] <Cadair> I wanted to use my old phone
[11:40] <Darkside> gsm/3g is also bad
[11:41] <Cadair> not for Tx but for sensors
[11:41] <Darkside> the rpi really isn't well suited as a tracker
[11:41] <Darkside> the only way you can get well-timed data out for modulation is to use the UART, which only gos down to 300 baud
[11:41] <Darkside> and with 10mW TX power that isn't always reliably
[11:41] <Darkside> we recommend 50 baud
[11:42] <Darkside> and you can't bitbang that with good enough reliability from within linux
[11:42] <Cadair> but it is well suited to being a cpu for sensors andwebcams
[11:42] <Darkside> yes, it is fine to look at webcams
[11:42] <Darkside> depending on the sensors you can do it on the avr just fine
[11:42] <Darkside> but is it not good as a primary tracker
[11:43] <Darkside> everyone here uses some kind of microcontroller
[11:43] <Darkside> and for good reason
[11:43] <Cadair> could use a gertboard
[11:43] <Cadair> think that has a arduino on it
[11:44] <Cadair> ok so we should think of something better to to the TX
[11:44] <Darkside> yes.
[11:44] <Darkside> use an arduino
[11:44] <Darkside> srsly
[11:44] <Darkside> or something arduino-like
[11:44] <Darkside> how were you planning on attaching the gps?
[11:45] <Cadair> http://www.adafruit.com/products/746
[11:45] <Cadair> and a breadboard or sthg, we haven't got that far
[11:45] <Darkside> i think that gps is ok up to 27km
[11:45] <Darkside> dunno about higher than that

[11:46] <Darkside> hell no
[11:46] <Darkside> the current HAB record is 44.3km
[11:46] <Darkside> my personal best is 40.5km
[11:47] <Cadair> What are the main things that determine the height?
[11:47] <Darkside> balloon size and how much gas is in it
[11:47] <jonsowman> day of the week
[11:47] <Darkside> and payload weight

[11:47] <jonsowman> oh yes

[11:47] <Darkside> cthulu worship
[11:47] <Darkside> etc
[11:48] <jonsowman> I should be at 50km by now if that's the case
[11:48] <Cadair> Darkside, that module will work with a rpi right?!
[11:48] <Darkside> Cadair: which one
[11:48] <Cadair> http://ava.upuaut.net/store/index.php?route=product/product&path=59_60&product_id=52
[11:48] <Darkside> the problem you're goign to face is the rpi only has one UART
[11:48] <Cadair> what's a UART?
[11:49] <Darkside> hardware serial port
[11:49] <Darkside> i.e. what you have to use to send the data to be transmitted, if you want any kind of accurate timing on it at all
[11:49] <Darkside> so...
[11:49] <Darkside> you have to do hacks to 'share' the single UART
[11:49] <Darkside> or you put the GPS on a usb port
[11:49] <Darkside> which means you have a heap more power draw
[11:49] <Darkside> use. a. microcontroller.
[11:49] <Darkside> srsly.
[11:50] <Darkside> we've been doing this for a loooong time now
[11:51] <jonsowman> agreed
[11:51] <UpuWork> +1 that
[11:51] <Cadair> But i wasts to use rpi
[11:51] <Cadair> for the funz
[11:52] <Darkside> then sure, still fly it
[11:52] <Darkside> have it record webcams and stuffs
[11:52] <UpuWork> would you perform surgery with an axe ?
[11:52] <Cadair> I don't know about the problems with it though
[11:52] <Darkside> but use an avr or something as your primary tracker
[11:52] <UpuWork> sure it will probably work but a scalpel will be better
[11:52] <Cadair> avr?

[11:54] <daveake> I have been beckoned to correct the errors of your ways :)
[11:55] <Darkside> hehe
[11:55] <daveake> Well, let's put it this way .... I only fly the Pi in conjunction with a separate, completely independent, reliable tracker
[11:55] <Cadair> make sense
[11:56] <Cadair> tbh, the tracker is the thing we haven't given a lot of thought to yet, we are still in the very early stages of planning this
[11:56] <daveake> TBH All 3 Pi flights, the Pi has worked 100%, if you discount me not tightening up the GPS plug on one of them :p
[11:56] <Darkside> tbh the tracker is the most important part
[11:56] <Cadair> so what did you do
[11:57] <Cadair> Darkside, I get that. But it is not as easy as rigging up some temp/pressure sensors and playing around with some electronics that none of us have any real experience in
[11:57] <daveake> However, if what you want is a simple reliable tracker, then get an Arduino or some other basic micro board. Not one with an operating system. Not one with an SD card. Not one with 10 times the power requirement of a simple tracker. Not one with a non-real-time OS
[11:58] <jonsowman> or any OS
[11:58] <daveake> An Arduino is no more difficult to program than a Pi. And it doesn't need any tricks of port sharing. And lots more people can help you on it.
[11:58] <daveake> Agree jonsowman :)
[11:58] <daveake> +d
[11:58] <Cadair> what can you code arduino in?
[11:58] <daveake> C
[11:58] <Daviey> daveake: Are you kidding?

[11:59] <daveake> Daviey I doubt it
[11:59] <Cadair> C is not python though
[11:59] <Cadair> :p
[11:59] <jonsowman> undeniable
[11:59] <Daviey> daveake: a full-blown OS is naturally easier to programme than a single-language Ardunio
[11:59] <daveake> Rubbish
[11:59] <UpuWork> not true
[11:59] <UpuWork> go ask project sharp about programming multitasking O/s's
[11:59] <jonsowman> for this application (HABs), that's not true
[12:00] <jonsowman> in general, perhaps it is
[12:00] <UpuWork> that said Dave's is the only payload with a GPU temperature readout
[12:00] <jonsowman> the application specific requirements make using a microcontroller significantly easier than trying to wrestle with an OS in order to coerce it into doing what you want

[12:00] <Cadair> UpuWork, yeah baby!
[12:00] <daveake> The stuff you need to do in a tracker is almost identical regardless of whether you have an OS underneath, as you talking to serial ports and waggling bits around.

[12:01] <Daviey> I think my head just exploded. I agree, a tightr environment that uses less power is a better fit for HAB.. But i strongly disgaree it's easier to programme.
[12:02] <daveake> Well, Daviey, I programmed both. I ported my Arduino code to the Pi in 2 hours including soldering up the GPS and radio. Going the other way would have taken the same time.
[12:02] <Cadair> ok,
[12:02] <Daviey> jonsowman: wrestle is a little emotive. Setting IO high or Low is just as flexible in python as it is in Ardunio's custom environment :)
[12:02] <Cadair> so daveake you actually used the pi for tracker tx and it worked?
[12:02] <Cadair> (yes yes i know)
[12:03] <Cadair> but actually it is a bit pants?
[12:03] <daveake> Yes, it worked. I had to cheat because of the non-real-time-ed-ness, but it worked
[12:03] <gonzo__> depends on your aproach. If you are from a PC background, where you want someone else to have done all the deviec interfacing, then an OS feels easier to use. If you are from an embedded background, they you will probably prefer having absolute control and access to the hw. So an OS is just an extra comoplication and more to go wrong
[12:03] <Daviey> daveake: so you agree with me? 2 hours to port, included electronic handling.. is pretty reasonable, surely?
[12:03] <daveake> My point is, going EITHER WAY would be the same
[12:04] <Cadair> what about using a arduino to do tx and the pi to do sensor read etc?
[12:04] <daveake> The bulk of the work is independent of if it's a Pi or Arduino
[12:04] <Daviey> right.. the hard part is developing the algorithm.. Which is pretty portable.
[12:04] <daveake> You can. You can split the load between Pi and Arduino however you like.
[12:05] <Cadair> how do you get them to talk to each other?
[12:05] <Cadair> without encountering the same issues as just using the pi?
[12:05] <daveake> Exactly. Decoding GPS (and there's an Arduino library for that); reading sensors (libraries); building Tx string (peasy), Txing (different on Pi and Arduino)
[12:05] <daveake> i2c would make sense. You can make an Arduino an i2c slavea easily
[12:06] <Cadair> ah cool
[12:06] <daveake> You have to ask though, what the Pi is adding
[12:06] <Cadair> Webcams, MOOOR sensors?
[12:06] <daveake> Those are possible answers yes
[12:07] <Cadair> just the fun of flying a pi
[12:07] <daveake> Well that's why I did my first
[12:07] <Cadair> an I have to agree that it is probably easier for me to program
[12:08] <daveake> Just remember, you want the thing back. Make the tracker as reliable as possible. IMO that means making it independent of whether the Pi is working or not.

[12:08] <daveake> A lose SD card can stop your tracker dead, for example
[12:08] <daveake> loose even
[12:08] <Cadair> oh loose sd cards
[12:08] <daveake> Descent can be a bit unfriendly
[12:09] <Cadair> yeah we already have that problem
[12:09] <Cadair> could make the arduino track indepentantly of the pi but you are getting less and less use out of the ting
[12:09] <Cadair> could make the arduino track indepentantly of the pi but you are getting less and less use out of the thing
[12:09] <daveake> Matters not. Reliability matters
[12:10] Hix (~Hix@87.194.200.92) joined #highaltitude.
[12:10] <Cadair> i mean there is less point to it's existance
[12:10] <daveake> Everything in the payload has to have a reason to be there.
[12:12] <Cadair> yeah, but for fun is probably a valid reason? :p
[12:13] <griffonbot> Received email: chris hillcox "Re: [UKHAS] Polystyrene foam thickness survey."
[12:13] <daveake> My Pi flights I do SSDV ("live"-ish images). That's easier, cheaper and seems to produce better quality images than using an AVR and a serial camera. So that in itself justifies the Pi being there. However, like I said, I won't fly one without having a solid tracker there too. So IMO even if you use a Pi, you should build a separate independent reliable tracker too.

[12:14] <daveake> Having a tracker that relies on a Pi *and* Arduino to work together just increases complexity and the likelihood it'll all go pear-shaped.
[12:14] <Cadair> so you have the pi and the avr completely separate like tx separately as well?
[12:15] <Cadair> or you make the avr just carry on if the pi falls over?
[12:15] <daveake> I would, and I do.

[13:08] <Randomskk> I guess all telem and then you can filter based on whether it was in a flight or not

[19:22] <arko> go!
[19:23] <Lunar_Lander> hello
[19:23] <Lunar_Lander> mclane, will you be at HAM RADIO at Lake Constance in June?
[19:23] <mclane> I am looking for an implementation of the ssdv protocol (encoder / decoder)
[19:23] <lz1dev> https://github.com/fsphil/ssdv
[19:24] <mclane> I have found that - is this the decoder side?
[19:24] <lz1dev> both
[19:25] NickSF (~NickSF@151.225.197.191) joined #highaltitude.
[19:28] <mclane> ok, seems to be non-trivial. Any more detailled description (I have read the wiki article and looking for something more detailled)
[19:28] <mclane> ?
[19:29] <costyn> evening all
[19:29] <mfa298> I think dl-fldigi might have the decode bits in it so you may only need to work on the encode side
[19:30] <mattbrejza> tahts the ATMEGA 644 version i assume too
[19:30] <mclane> Lunar_Lander: no concrete plans
[19:30] <costyn> question about habamp: we should see a difference in signal strength even in a desktop test setup when we apply power and when there's no power right?
[19:30] G8KNN-Jon (~Jon@cpc1-cmbg10-0-0-cust144.5-4.cable.virginmedia.com) joined #highaltitude.
[19:31] <mattbrejza> the habamp needs power
[19:31] <costyn> nothing seems to happen when we gave it 5v
[19:31] <mattbrejza> otherwise its a habatt
[19:31] <SP9UOB_Tom> habatt LOL ;-)
[19:31] <costyn> :)
[19:32] <Lunar_Lander> xD
[19:32] Action: SP9UOB_Tom 's freezer does the job: $$$$$$SP9UOB,114,00:00:00,0,0,0,0,0,0,128,-20*42BB
[19:32] <SP9UOB_Tom> -20 deg C
[19:33] <mattbrejza> when ours was broken it went down to -30
[19:33] <costyn> but we should see some sort of change when applying power?
[19:33] <mattbrejza> well you wont notice much difference between with habamp and without habamp when the signal soruce is right next to you
[19:33] <costyn> say at a point in time + and - were reversed, could this have broken it?
[19:34] <costyn> mattbrejza: ok
[19:34] <mattbrejza> that can have sad results yes
[19:34] <SP9UOB_Tom> could somebody cange the topic to: the habamp needs power otherwise its a habatt
[19:34] <SP9UOB_Tom> ?
[19:34] <SP9UOB_Tom> change ;-)
[19:34] <fsphil> mclane: yea that code is both encoder and decoder
[19:36] <mclane> meanwhile I found your HADIE code, fsphil
[19:36] <mclane> I will try that on an ARM micro next time
[19:36] <Lunar_Lander> fsphil, what was the uC in HADIE?
[19:37] <chrisstubbs> Is the radar reflector a legal requirement on a 300g balloon with approx 350g payload?
[19:38] <fsphil> atmega644p Lunar_Lander
[19:39] <fsphil> mclane: I believe that code uses an early version for the format, I'll check
[19:39] <Lunar_Lander> ah
[19:39] <fsphil> for/of
[19:39] <Lunar_Lander> and you attached that camera module to UART 1 of it?
[19:40] <fsphil> 0 I think Lunar_Lander
[19:40] <Lunar_Lander> ah
[19:40] <mclane> I am working with a lpc1227; this chip has 2 UARTs
[19:40] <Lunar_Lander> why do people succeed in operating camera modules with arduinos?
[19:40] choppyhorse (~K@eyang.me.stevens-tech.edu) joined #highaltitude.
[19:41] <mclane> the task is not that computation-intensive
[19:41] <mclane> if you use a camera whith integrated processor
[19:41] <mclane> where you can read the picture data via UART
[19:42] <fsphil> yea, this is much simpler than processing raw images
[19:42] <Lunar_Lander> well
[19:42] <fsphil> mclane: I've pushed an update
[19:42] <mclane> I have a linksprite camera
[19:42] <fsphil> the crc was changed
[19:42] <Lunar_Lander> that LinkSprite thing that I got from sparkfun seems to do that
[19:42] <Lunar_Lander> if you want to have a look https://www.sparkfun.com/products/10061
[19:43] <fsphil> I've tested images from a linksprite, they seem to work but nobody has flown one
[19:43] <mclane> fsphil: thanks; will use that as a reference
[19:43] <Lunar_Lander> kostas flew one
[19:43] <Lunar_Lander> i.e. nosebleed
[19:43] <fsphil> there is also a volatile variable in there mclane, you probably don't need that
[19:43] <fsphil> it was to work around an avr-gcc bug
[19:43] <fsphil> which might even be fixed by now, might not need it myself
[19:44] <Lunar_Lander> mclane, to what uC would you connect the camera?

[19:46] <fsphil> I suspect it's about 2k
[19:46] <mfa298> mclane: it might be worth talking to craag when he's around as I know he started looking at getting ssdv to work on some form of arm cortex
[19:47] <Lunar_Lander> mclane, ah ok
[19:47] <fsphil> someone else used it on arm
[19:47] <fsphil> I can't remember who now

[19:48] <mfa298> fsphil: are you thinking of craag at the weekend ?
[19:48] <mfa298> or has someone else tried as well ?
[19:48] <fsphil> no, this was last year
[19:48] <mclane> some first results here: www.stratosphaere.net

[20:08] <Lunar_Lander> mclane, how much volts do you give into the camera?
[20:08] <Lunar_Lander> *how many
[20:09] <mclane> 3.3V
[20:09] M0NSA (~HeliosFA@requiem.soton.gia-lan.co.uk) left irc: Read error: Connection reset by peer
[20:09] <fsphil> all the uart cameras seems to be 3.3v only
[20:10] M0NSA (~HeliosFA@requiem.soton.gia-lan.co.uk) joined #highaltitude.
[20:10] <Lunar_Lander> well the linksprite normally runs at 5
[20:10] <fsphil> I think only the rs232 version of the 4d systems camera did 5v
[20:10] <Lunar_Lander> but can run at 3.3V with lower baud rate
[20:11] <fsphil> nice
[20:11] <mclane> I tried the default 38400 baud which works ok
[20:11] <fsphil> that makes it easier for some people
[20:11] <Lunar_Lander> OK
[20:11] <fsphil> I actually ran mine at 9600, cause I'm transmitting at 300 baud there's no point rushing :)
[20:11] <Lunar_Lander> do you think my arduino mega which runs all of the balloon already could also run the linksprite?
[20:12] <Lunar_Lander> I got Serial 0 and 3 vacant but I got that it also runs with software serial
[20:12] <fsphil> if you've the space (RAM + flash), a free uart and the time to program it
[20:12] <mclane> yea agree to fsphil
[20:13] <fsphil> one issue I had with the C328-based cameras was they'd sometimes fall asleep between packets
[20:13] <mclane> I run it with a 32 byte buffer to receive image datachunks
[20:14] <Lunar_Lander> would it be compatible to an openlog?
[20:14] <mclane> and write them immediately to an sd card
[20:14] <fsphil> hopefully the linksprite doesn't mind
[20:15] <fsphil> atmega's just don't have the memory to store an entire image
[20:15] Nick change: choppyhorse -> Bulbasaur
[20:15] Nick change: Bulbasaur -> Oddish
[20:15] <Lunar_Lander> yea
[20:15] Nick change: Oddish -> choppyhorse
[20:15] <mclane> my lpc also has only 8k RAM and a 640x480 picture is some 40k
[20:16] <mclane> so I read it piece by piece and write to sd card
[20:16] <Lunar_Lander> currently the arduino runs the GPS and sensors, assembles the string, transmits at 50 bauds and then actuates the openlog on UART2 to save it
[20:16] <fsphil> if the linksprite doesn't mind pausing then it's not an issue
[20:17] <fsphil> if you've four uarts, why are you using software serial Lunar_Lander?
[20:17] <mclane> I did not try that

[20:17] <Lunar_Lander> yeah I was just thinking
[20:17] <Lunar_Lander> I got a geiger counter as well that can do serial and Pulse
[20:17] <fsphil> I must give it a try
[20:18] <Lunar_Lander> maybe we would use Pulse when we hook it up for flight 2
[20:18] <fsphil> I've got a linksprite somewhere
[20:18] <mclane> furthermore, I am looking to run the whole stuff with a RTOS
[20:19] <mclane> so I can run parallel threads
[20:19] <mattbrejza> interrupts ftw
[20:19] <mclane> 50 baud rtty leaves the cpu in an idle loop most of the time

[20:40] <Lunar_Lander> mclane, I once rebuilt the JPEG Trigger of sparkfun but it didn't work
[20:40] <Lunar_Lander> with that I mean
[20:40] <Lunar_Lander> there was a test program creating a 100 line text file on an SD card
[20:40] <Lunar_Lander> that worked well
[20:40] <Lunar_Lander> in connection with the linksprite, it only got 0 byte files

[20:51] <jonsowman> chrisstubbs: you should totally just come to the cusf site and launch
[20:51] <Lunar_Lander> you power it off a lipoly and attach a Linksprite camer

[20:56] <daveake> The only way is (off the coast of) Essex
[20:56] <jonsowman> assuming we are free, 24 hours
[20:56] <jonsowman> chrisstubbs: ^
[20:56] <chrisstubbs> haha I have had a handful of forecasts landing in kent, which would be perfect!
[20:57] <chrisstubbs> And thanks jonsowman I will keep that in mind :) We wont trouble you for helium equipment or chasing (unless you want to of course!) Just use of the launch site would be much appreciated.
[20:58] <mclane> Lunar_Lander: ah ok. But I preferred to do it myself since I also want to send rthe images to the ground
[20:58] <jonsowman> that's fine

[20:59] <Lunar_Lander> mclane, yeah, as I said I got the parts, save for the stepup that they have and I copied the circuit

[20:59] <Lunar_Lander> and the CPU seems to be able to write to the SD card via the level shifter
[20:59] <Lunar_Lander> but something in controlling the camera seems to be not working
[20:59] <Lunar_Lander> the camera works when I attach it to the PC with a FTDI
[21:00] <fsphil> Lunar_Lander: did you check you have the correct version, and not the trigger for the C328 camera they used to sell
[21:00] <Lunar_Lander> that is the 2.0 version
[21:00] <Lunar_Lander> and the text says it is for the linksprite
[21:01] <Lunar_Lander> the first sentence says

[21:09] <fsphil> nice little camera that was
[21:09] <Lunar_Lander> yea
[21:09] <Lunar_Lander> I mean the JPEG library that sparkfun supplies has a test program

[21:19] <Lunar_Lander> ok
[21:19] <Lunar_Lander> could there be a timing issue?

[21:30] <nigelvh> Did you measure the capacitance? Because often the crystals will run without the capacitors, they're just more stable with them.

[21:48] <gonzo__> yep, remember them well
[21:49] <gonzo__> but there was another chip min the family with some extra peripherals on?
[21:49] <fsphil> they don't have any gpio lines, which is scary. I can just about figure out how to wire up a ROM chip :)

[21:50] <fsphil> it's mostly an educational thing

[21:53] <fsphil> not watched that either sadly
[21:53] <nigelvh> fsphil, a cheap divider would be a serial in parallel out shift register.
[21:54] <fsphil> how would I interface it to the processor though?
[21:54] <fsphil> it basically does everything though the memory bus
[21:55] <nigelvh> Well, crystal goes on the serial in, and your divided clock signal comes out from one of the parallel pins. You choose which one based on what division you want. As for where it goes into the micro, it should go in exactly where a crystal would go in.
[21:55] <fsphil> aah, for the clock
[21:55] <nigelvh> Yes
[21:56] <fsphil> for some reason I'd jumped ahead to uarts
[21:56] <nigelvh> Simple and cheap divider

[22:01] <Lunar_Lander> yea
[22:01] <Lunar_Lander> is the coax for the antenna OK?
