[00:00] <nats`> that's not true anymore
[00:00] <nats`> I did some years ago
[00:01] <nats`> but I gave up about 8 month ago
[00:01] <oh2kku> you just don't have new enough asic machines
[00:01] <nats`> :D
[00:01] <oh2kku> but then again maybe the miners are just dumb and do it to lose money
[00:02] <nats`> a big part of them yes
[00:02] <nats`> that's a little too late to rush into that
[00:03] <oh2kku> the hash rate graph has an impressive slope nowadays
[00:04] <oh2kku> (never mined/owned/used any btc)
[00:05] <nats`> the thing I would love to do is to grab all the bruteforcing power
[00:05] <nats`> :D
[00:08] <SpeedEvil> asics are useless for other things
[00:09] <nats`> so much square centimeter of silicon lost :|

[00:17] <SpeedEvil> it would have a density of about 10*air
[00:17] <SpeedEvil> I want to use it to line a tiny rapid heating oven.
[00:17] <heathkid> use more and lighter helium!

[00:17] <nats`> you need a rocket to fly that :p
[00:17] <nats`> a oven to do what ?
[00:18] <arko> use a vacuum, it's lighter than air
[00:18] <SpeedEvil> I want a proper multimode oven.
[00:18] <nats`> multimode ?
[00:18] <nats`> for reflow ?
[00:18] <SpeedEvil> steam, IR, convection, and the ability to come to heat in 30s.
[00:18] <SpeedEvil> food too.

[00:50] <WillTablet> Though I do disagree with strike action

[04:32] <DL7AD> lol okay.
[04:32] <enkidu> C++ is okay, especially with Qt
[04:32] <DL7AD> if you know a programming language every other language is easy to learn
[04:33] <DL7AD> never worked with c++ ^^ and now i do
[04:34] <enkidu> I switched to C++ from PHP
[04:35] <enkidu> now I even write some CGI apps with C++, as it is more powerful

[06:19] <Mik_WD8MNV> if people are using what is actually a tranceiver chip for their trackers... has anyone thought about building a receiver around that same module?
[06:20] <la3eq> quess it is cheaper to just buy a $20 RTL stick and use that as a receiver.
[06:21] <Mik_WD8MNV> for portable use instead of say an ft817

[07:46] <G0TDJ_Steve> Hey Felix :-)
[07:48] <G0TDJ_Steve> I see SP3OSJ is up
[07:48] <DL1SGP> yeap, taking to float :D
[07:48] <G0TDJ_Steve> Yeah, I see some interesting predictions on the map
[07:49] <DL1SGP> you mean heading towards UK :D
[07:49] <G0TDJ_Steve> Yep :-)
[07:49] <G0TDJ_Steve> He was going for a float as I recall. Perhaps trying to do a 'Leo' :D

[07:51] <DL1SGP> indeed, and floaters like Denmark at present
[07:51] <DL1SGP> I fear it will be a bit too far north of me but we gonna see
[07:51] <DL1SGP> also weather is quite a challenge for the flight
[07:51] <DL1SGP> this morning radio greeted me "If you are from northern Germany you might be wondering why it still is as dark, do not worry, that is just the weather"
[07:52] <G0TDJ_Steve> LOL.. Cripes. We're supposedly getting rain here and I've woken up to a bright sunny morning?
[07:52] <DL1SGP> yes well I hope he has more luck with floating this time, in the past the goddess of the mythical floats was not with him too much, but I guess after a few trackers having been sacrificed she will be willing to let it float now

[07:53] <DL1SGP> indeed
[07:53] <G0TDJ_Steve> I just noticed the solar input too.. Cool.
[07:54] <Mik_WD8MNV> and if it somehow goes sour, let it be over land
[07:54] <G0TDJ_Steve> We can hope Mik
[07:55] <DL1SGP> if it should come close equipment is ready, as usual
[07:55] <G0TDJ_Steve> What area are you in Felix?
[07:55] <DL1SGP> Hannover
[07:56] <DL1SGP> or if you know a bit about British Forces in Germany Celle/Bergen Area :D
[07:56] <DL1SGP> though... they are almost all gone now :(
[07:56] <G0TDJ_Steve> Sadly, my goegraphy is really bad, second only to my math LOL :D

[08:04] <DL1SGP> checking on tropo conditions
[08:05] <G0TDJ_Steve> Got you now :-)
[08:07] <DL1SGP> tropo not really useful in the north, quite good in south italy!
[08:07] <G0TDJ_Steve> It's going up really slowly
[08:08] <DL1SGP> better slow ascent than fast descent
[08:09] <G0TDJ_Steve> True

[08:13] <Mik_WD8MNV> any estimates as to what alt it will float at?

[08:17] <fsphil> multi-balloon foil? I'm betting it won't float
[08:17] <G0TDJ_Steve> Hows that Phil?
[08:17] <ibanezmatt13> I have an error when I compile my program saying "conversion from double to float could result in possible loss of data," and that makes it fail. How can I get around that?! https://gist.github.com/ibanezmatt13/6919236
[08:18] <fsphil> that won't make it fail ibanezmatt13

[08:19] <ibanezmatt13> wait
[08:19] <fsphil> G0TDJ_Steve: there's always one balloon slightly more filled than the others, and it tends to burst. the dead weight of it will bring it slowly down
[08:19] <ibanezmatt13> nah, sorry it's something else. Just realised another error

[08:19] <G0TDJ_Steve> Cheers fsphil
[08:19] <daveake> Something else ...
[08:20] <fsphil> G0TDJ_Steve: or maybe I'm not being optimisic enough :)
[08:20] <G0TDJ_Steve> :-)
[08:20] <daveake> ... time from some GPS units will have fractions of a second
[08:20] <fsphil> my predictions for pico balloons have been mostly wrong before
[08:20] <daveake> Your code refuses to accept a time like 12:34:56.78 for example
[08:20] <daveake> Which I've seen (though I don't remember which gps)
[08:21] <ibanezmatt13> err, should be fine for Ublox I believe
[08:21] <daveake> yes
[08:21] <fsphil> seen it too, also don't remember
[08:21] <daveake> just saying that it might not always work
[08:21] <fsphil> was my old usb gps module I think
[08:21] <ibanezmatt13> daveake, apparently the error is that the setLatitude identifier is not found. But I really can't see how that is so
[08:22] <daveake> ublox /should/ do it too if set for >1 reading per second
[08:22] <fsphil> ibanezmatt13: C reads from the top to the bottom
[08:22] <daveake> So it's worth fixing now rather than having a bug later if you need faster updates
[08:22] <ibanezmatt13> oh
[08:23] <ibanezmatt13> so the function needs to be declared before it gets to the call bit, aaah
[08:25] <mikestir> or you can add a forward declaration
[08:25] <mikestir> instead of the whole function
[08:25] <daveake> In some languages that's not needed, in which case the compiler has to pass through the code twice (at least) so it picks up the declaration at the bottom before the usage above it
[08:27] <ibanezmatt13> right, I've put all the parsing code into its own function and I've put the main() at the bottom that calls it. But the parsing function and the latitude function reference each other, so I'm not sure how I can get around that: https://gist.github.com/ibanezmatt13/6919236
[08:28] <ibanezmatt13> so the parse_NMEA() calls set latitude, and setLatitude() calls parse_NMEA :/
[08:28] <fsphil> dangerous
[08:28] <ibanezmatt13> dangerous...
[08:29] <daveake> dangerous
[08:29] <ibanezmatt13> cool
[08:29] <ibanezmatt13> :/
[08:29] <daveake> this isn't a "how do I get it to compile" question
[08:29] <daveake> (easy answer to that - forward declaration)
[08:30] <daveake> Generally, if A calls B calls A, you've got it wrong
[08:30] <ibanezmatt13> oh right
[08:31] <ibanezmatt13> well, A calls B to get the latitude sorted, and if the latitude cannot be sorted, B calls A again to retry
[08:31] bertrik (~quassel@rockbox/developer/bertrik) joined #highaltitude.
[08:31] <ibanezmatt13> Which from a Python mind makes logical sense, but...
[08:31] <daveake> not really
[08:31] <daveake> this isn't a language thing
[08:31] <daveake> this is a "program gets stuck A calling B calling A ad infinitum" thing
[08:32] <number10> you can have A call A but I dont think we should go there
[08:32] <ibanezmatt13> that happens too :/
[08:32] <daveake> ibanezmatt13 There are some valid reasons for doing "A calls A" or "A calls B calls A", but they're rare
[08:33] <mikestir> you need to really know what you are doing if you are going to do any kind of recursive function calling in C

[08:33] <daveake> And I can guarantee that this isn't one of them :)
[08:33] <mikestir> absolutely
[08:34] <ibanezmatt13> I can't think how else to do it if I'm honest
[08:34] <mikestir> B returns value to indicate success or failure, and A takes appropriate action
[08:35] <mfa298> the usual method would be to always return something but have something that indicates an error occured
[08:35] <ibanezmatt13> ah I see
[08:35] <ibanezmatt13> So I have a boolean like: latitude_ok = check_latitude(latitude);
[08:36] <ibanezmatt13> then in the same function, if latitude_ok = true { do all the stuff }
[08:36] DL1SGP (~DL1SGP@dhcp38.signon1.uk.beevpn.com) joined #highaltitude.
[08:37] <mfa298> one of the standard solutions might be to return -1 for an error, but that won't be a good solution here for (hopefully) obvious reasons
[08:38] <ibanezmatt13> erm, I can't see why not :/
[08:39] <mfa298> what happens if the payload goes to the southern hemisphere ?
[08:39] <ibanezmatt13> couldn't it still return -1 for an error?

[08:44] <ibanezmatt13> lol
[08:45] <mfa298> you could decide that it's highly unlikely that it will ever cross the equator and treat -1 as an error but make sure you make a note (or several) in the code otherwise you'll forget (or someone else will try using it and make an assumption it's safe)
[08:46] <ibanezmatt13> can't I just return true or false/
[08:46] <mfa298> you could also use an impossible value to indicate an error (but again document it)

[14:10] <qyx_> ah, i am blind
[14:10] <qyx_> yep
[14:10] <ibanezmatt13> :)
[14:11] <qyx_> also you are sprintf-ing to a char array of undefined length
[14:11] <ibanezmatt13> I'll try it with length 100
[14:12] <qyx_> char datastring[] = "";
[14:12] <ibanezmatt13> woo success! Thanks qyx_
[14:12] <qyx_> means you are allocating pointer to char pointing to empty null terminated string
[14:12] <ibanezmatt13> ah I see
[14:12] <qyx_> you were probably overwriting some other variables
[14:13] <ibanezmatt13> makes sense
[14:13] <ibanezmatt13> I must say, working so much with strings in C (basically pointers) has really helped me to understand what's going on with pointers. They make so much sense for some things.
[14:13] <ibanezmatt13> eroomde, ^
[14:14] <DL1SGP1> so looks like today the Polish based launch station strike back on the Float-Mageddon
[14:14] <ibanezmatt13> learning a language like C really helps with one's understanding of computers in general
[14:14] <mfa298> they make sense for quite a few things.
[14:15] <mfa298> using pointers is probably the best way to solve the issues you were having earlier with the latitude conversion function call
[14:15] <ibanezmatt13> They definitely make sense for strings. I've not seen any other area where they are useful yet but I think I'd rather wait for a bit until I get to that point. :)
[14:15] <OZ1SKY_Brian> SP3OSJ good thing the cold war ended, or else it would never have gone that far :-)

[14:15] <eroomde> oh right
[14:15] <eroomde> i just read it

[14:16] <eroomde> cool
[14:16] <eroomde> yes
[14:16] <eroomde> so pointers are a thing that basicallt explain all of C
[14:16] <ibanezmatt13> I am starting to realise that, yes
[14:16] <eroomde> and once you get pointers, most of C falls into place
[14:16] <ibanezmatt13> yep, little steps
[14:16] <eroomde> i wish the same was true of patterning features in solidworks
[14:17] <ibanezmatt13> no idea what that is :P
[14:17] <SP3OSJ> OZ1SKY: Like the Cold War, it was not me I was flying in the balloon
[14:18] <ibanezmatt13> mfa298, I believe I am ready now for sorting out a function to sort out the latitude/longitude. That is next on my list. I tried to make my own adaption of the function I looked at of yours but after what happened this morning, I ended up ditching it
[14:19] ejcspii (~hp@c-71-228-250-95.hsd1.tn.comcast.net) left irc: Quit: ejcspii
[14:19] <mfa298> in terms of how to deal with it failing or not possibly the best trick is to just have the function return something like true/false.
[14:20] <mfa298> if you're doing that then you need to get the converted value back somehow and that's where pointers can be useful.
[14:20] <ibanezmatt13> So have a function that simply *checks* lat and lon
[14:20] <OZ1SKY_Brian> SP3OSJ 220dB s/n, good copy
[14:20] <mfa298> you end up doing something like sscanf does.
[14:20] <OZ1SKY_Brian> 22 sri

[14:20] <ibanezmatt13> mfa298, when you say get the converted value back, I thought it would just return a false or true boolean?
[14:21] <SP3OSJ> I always try to work well
[14:21] PE2G (Miranda@a83-161-208-176.adsl.xs4all.nl) left #highaltitude.
[14:22] <OZ1SKY_Brian> getting close to max elevation
[14:22] <mfa298> well a function can only return one item (like sscanf returns the number of items it processed)
[14:22] <mfa298> but you can get data back in other ways (like you're getting data from sscanf)
[14:23] <mfa298> this is where pointers start becoming useful
[14:23] <ibanezmatt13> I see
[14:23] <ibanezmatt13> Not 100% sure where I would start in doing something like this
[14:24] <mfa298> in the sccanf function do you understand whats the &lock argument is doing
[14:24] <SP3OSJ> OZ1SKY_Brian: I was a soldier. What was the Cold War that Poland had attacked Denmark (World War 3). This is not a joke! Russia would attack Germany
[14:25] SpeedEvil (~quassel@tor/regular/SpeedEvil) joined #highaltitude.
[14:25] <ibanezmatt13> I think so, it's telling sscanf to store the data it got at the address of the variable lock?
[14:25] HeliosFA (~HeliosFA@requiem.soton.gia-lan.co.uk) left irc: Ping timeout: 260 seconds
[14:26] <qyx_> exactly
[14:26] <mfa298> that sounds about right.
[14:27] <mfa298> so you can do something similar with your conversion function.
[14:27] <ibanezmatt13> And how does that link into the parse_latitude function I'm about to create?
[14:27] <OZ1SKY_Brian> SP3OSJ yes i know, nato had some big installations on bornholm island and south east seeland, to look out for poland.
[14:27] HeliosFA (~HeliosFA@requiem.soton.gia-lan.co.uk) joined #highaltitude.
[14:27] <mfa298> you pass it a pointer to the char array, and a pointer of where to store the result
[14:28] <ibanezmatt13> ah and it still returns true or false
[14:28] <OZ1SKY_Brian> SP3OSJ now we just do peacefull invations :-)
[14:28] <ibanezmatt13> if it was true, the converted data is in a specific location?
[14:28] <ibanezmatt13> is that how the poiners come into it?

[14:30] <OZ1SKY_Brian> SP3OSJ does the beebs have any meaning?
[14:31] <ibanezmatt13> So I think I get the way the function will operate and what the pointers will do, but now I just need to figure what to do to get the latitude in the right format
[14:31] <ibanezmatt13> then I can go play :)

[14:32] <SP3OSJ> OZ1SKY This saves energy Ping-Pong
[14:32] <mfa298> inside your function you then have to tell it that it's using a pointer and that's where the * notation comes in. So defining the value as a float *
[14:32] <OZ1SKY_Brian> SP3OSJ yes, was just wondering if they had other meaning

[15:33] <malgar> ahh ok.. you mean too high = too much time between a sample and another, right?
[15:36] <bertrik> no, with too high I mean the sample rate, higher sample rate -> smaller time between samples
[15:37] <bertrik> I think the hardware can do 2.8 Ms/s, but there a good chance, some samples are skipped/dropped somehow and not seen by the software

[17:37] <mfa298> C++ mostly just adds a few things on top of C
[17:38] <ibanezmatt13> So you think I should just do it as an arduino program?
[17:38] <mfa298> you might want to check the format for longitude
[17:38] <ibanezmatt13> Yeah, I thought it was the same as latitude but I'm not sure

[17:41] <ibanezmatt13> malgar, why don't you just do an entirely Pi based payload?
[17:42] <mfa298> malgar: you could do it all on the pi, or have the pi send data to the arduino using something like serial or spi
[17:42] <mfa298> or have a seperate arduino tracker and pi ssdv

[18:54] <ibanezmatt13> So Serial.read() will read one byte from the serial buffer. So, must I have a while loop that continuously reads until it sees ""
[18:54] <ibanezmatt13> I'm just wondering how people generally input the NMEA sentence from the serial port on Arduino
[18:56] <mikestir> have you considered decoding it on the fly using a state machine?
[18:56] <ibanezmatt13> erm, I'm not quite sure what one of those is
[18:57] <mikestir> http://en.wikipedia.org/wiki/Finite-state_machine
[18:57] KD8ATF (~KD8ATF@mobile-166-147-117-219.mycingular.net) left irc: Ping timeout: 272 seconds
[18:58] <mikestir> basically you handle the input differently depending on what state you are in
[18:58] KD8ATF (~KD8ATF@166.137.109.32) joined #highaltitude.
[18:58] <mikestir> and the input you receive in each state can determine what state change occurs
[18:58] <mikestir> you can implement it in C using a switch/case statement called in a loop, where you pop one character from the serial each time round the loop
[18:59] <mikestir> to begin with you would be in "idle" state, and you'd remain there until you received a $, after which you'd start processing the first field
[18:59] <mikestir> and so on
[18:59] <ibanezmatt13> erm, I guess I could try something like that. But I think for now I'd like to stick to just reading it in to a string from the serial port in the simplest way (I'm not that experienced)
[18:59] <mikestir> you can then sift the fields you are interested in directly into the right buffers and ignore the ones you don't care about
[18:59] <ibanezmatt13> isn't that kind of what I'm doing already?
[19:00] daveake (~Dave@daveake.plus.com) joined #highaltitude.
[19:00] <ibanezmatt13> evening
[19:01] <mikestir> haven't seen your code. you could read a whole NMEA string using a simplified state machine that would start on a $ and end on a CR/LF
[19:02] <ibanezmatt13> so I could write a loop that keeps reading bytes in until it sees a $ and then from there it appends each character to the string and then when it sees the cr/lf, it stops reading
[19:02] <mikestir> yes, and calls the processing function
[19:02] <mikestir> and of course you should always check that you haven't overflowed the buffer
[19:03] <ibanezmatt13> how do I check that before it has already been overfilled?
[19:03] chris_99 (~chris_99@unaffiliated/chris-99/x-3062929) joined #highaltitude.
[19:03] <ibanezmatt13> Ah, I check the length of the string at each iteration of the loop?
[19:03] <ibanezmatt13> and if it's less than what I specified for the string, continue reading?
[19:04] <mikestir> unless there is some special arduino string I'm not aware of, you're just filling a character array, yes?
[19:04] <ibanezmatt13> yes
[19:04] <ibanezmatt13> char* lestring
[19:04] <mikestir> in which case you will have a pointer (or offset) that you need to increment
[19:04] <mikestir> you just need to check that the pointer doesn't lie outside of the array bounds after you increment it
[19:05] <mikestir> if it does then (in this case) you'd have to abandon that string and go back to looking for a $
[19:05] <ibanezmatt13> I'm a little lost now :/ What does the pointer do exactly?
[19:05] KD8ATF (~KD8ATF@166.137.109.32) left irc: Ping timeout: 272 seconds
[19:05] <ibanezmatt13> I understand things when they're explained to me as if I'm an idiot. :) Really works
[19:05] <mikestir> you declare a buffer of (say) 16 bytes by doing something like char buffer[16], yes?
[19:05] <ibanezmatt13> yep, got that
[19:05] <mikestir> but you need to keep hold of that original pointer 'buffer', because you'll need to know where the start of the string is
[19:06] <ibanezmatt13> keep hold of it?
[19:06] <mikestir> so you can copy it to a pointer char *ptr = buffer; which you would do whenever you go back to looking for a new string
[19:06] <mikestir> yes - if you were to increment the variable 'buffer' then you'll no longer have a pointer to the start of the string
[19:07] <ibanezmatt13> sorry, I still don't quite get thsi
[19:07] <ibanezmatt13> this
[19:07] <mikestir> how are you appending to the string? do you keep a counter and do something like string[n] = value_read_from_serial?
[19:08] <ibanezmatt13> Well, I've not got to the bit where I append to the string, I just need some hints on how to do it because I'm not sure
[19:08] <ibanezmatt13> all I've got currently is a parsing funciton
[19:08] oh1co (554c8e9f@gateway/web/freenode/ip.85.76.142.159) left irc:
[19:08] <ibanezmatt13> I've not figured a way at all to read the actual sentence into a string which I can pass to the parse function
[19:09] <mikestir> ok, in C your string is just a pointer to a location in memory. it doesn't know anything about length or appending - you have to keep track of that yourself
[19:09] <ibanezmatt13> ok
[19:09] Willdude123 (~Willdude1@unaffiliated/willdude123) left irc: Ping timeout: 240 seconds
[19:09] <mikestir> so when you declare an array to hold a string, like char buffer[16], you are asking for 16 consecutive bytes of RAM, and the variable 'buffer' is a pointer that holds the address of the first of those 16 bytes
[19:10] <ibanezmatt13> ok got that
[19:10] <mikestir> you can access any one of those bytes by doing something like buffer[0] = 1; buffer[1] = 2;
[19:10] <ibanezmatt13> yep
[19:11] schoppenhauer (~quassel@unaffiliated/schoppenhauer) joined #highaltitude.
[19:11] <mikestir> so one way that you could do this is to keep an offset value (as an int), that you reset to 0 when you start searching for a $, then once you find it you keep incrementing it each time around the loop
[19:11] <ibanezmatt13> when do I know when to terminate the loop?
[19:11] <mikestir> so to append the character you'd be doing something like buffer[n++] = new_char_from_serial;
[19:11] <mikestir> you'd terminate the loop in this case when n == 16
[19:11] <mikestir> or if you hit a CR/LF
[19:12] <ibanezmatt13> aaah
[19:12] ejcspii (~hp@c-71-228-250-95.hsd1.tn.comcast.net) joined #highaltitude.
[19:12] <ibanezmatt13> ok so how do I know when I've hit cr/lf?
[19:12] <mikestir> hitting it because n==16 would be an error condition (your buffer is too small or the data was corrupted)
[19:12] <mikestir> if (new_char_from_serial == '\r')
[19:13] <ibanezmatt13> aaah right
[19:13] <ibanezmatt13> that's basically everything I needed to know :)
[19:13] <ibanezmatt13> thank you
[19:13] <mikestir> np
[19:13] <mikestir> you may also see the buffer accessed using a pointer, which is the char *ptr = buffer thing I was talking about
[19:14] <ibanezmatt13> yeah, I'll have a re-read of that bit
[19:14] <ibanezmatt13> yeah I think I get that now
[19:14] <mikestir> you should probably use the array method for now - it will be easier to understand
[19:14] <ibanezmatt13> yes, I'll stick with that for now
[19:15] <ibanezmatt13> I'm gonna write some psuedo code to help me remember that
[19:15] <mikestir> once you get it working you can add some extra states to your FSM that detect the * and check the checksum, then you can ignore any bad NMEA strings
[19:16] <mikestir> switch/case based state machines are very useful, particularly on embedded devices where you don't have an OS
[19:16] <ibanezmatt13> I looked into that but I thought for now to avoid more confusion I'd just read some sort of NMEA sentence in, then just check a couple of fields to see if it's ok
[19:16] <ibanezmatt13> yea
[19:16] <mikestir> sure - it's unlikely to pick up any errors
[19:16] <mikestir> anyway I have a door to paint. biab

[19:34] <mfa298> you might want to check what Serial.read() returns as a first step
[19:35] <ibanezmatt13> it returns the byte it read from the serial port, or a -1 if it didn't read anything
[19:36] <RocketBoy> buffer is an array - so (buffer == "$") is trying to compare the address of the buffer with the string "S"
[19:36] <ibanezmatt13> oh
[19:36] <mfa298> the key there is that it's a byte (not multiple bytes)
[19:37] <ibanezmatt13> So I need to convert the byte into a string each time I want to store it or compare it with something?
[19:37] <mfa298> or go the other way.
[19:38] <mfa298> all your comparisons are for a single byte
[19:38] <ibanezmatt13> not sure what you mean?
[19:38] <ibanezmatt13> oh
[19:38] <ibanezmatt13> yes
[19:38] <ibanezmatt13> So you mean, keep appending them to a byte array?
[19:38] <ibanezmatt13> and convert to string when done
[19:39] <RocketBoy> so what you want to do is read the serial port until you get a '$' then read it until you don't get a '$' then read that value and all the others until you get a newline or get to the end of the buffer

[19:40] <ibanezmatt13> hmm
[19:41] <ibanezmatt13> I'm still unsure
[19:41] <f5vnf> \nick f5vnf_
[19:42] Nick change: f5vnf -> f5vnf_
[19:43] <mfa298> each read from Serial.read gives a character (byte) so what variable could you use that holds a single character
[19:44] <nats`> is there any map for rtty station in france I would like to some test
[19:44] <RocketBoy> is there a string read like Serial.gets() ?
[19:44] <ibanezmatt13> mfa298, char?
[19:44] KiwiDean (~Thunderbi@100.144.69.111.dynamic.snap.net.nz) left irc: Quit: KiwiDean
[19:44] <RocketBoy> that would make it simpler
[19:44] <DL1SGP1> nats`: standard broadcast rtty like weather services?
[19:44] <ibanezmatt13> RocketBoy, there's a function that gets x number of bytes from serial port
[19:44] <mfa298> ibanezmatt13: char would be good
[19:45] <nats`> any on 430/440 MHz
[19:45] <nats`> I would like to see if my setup is working
[19:45] <ibanezmatt13> ok mfa298, I understand that bit :) nothing else
[19:45] <SP9UOB-Tom> argh. i2c read wasnt good idea...
[19:45] <DL1SGP1> ah hmm... that may be tricky to find, unless you know somebody around you

[19:46] <nats`> that's what I think too
[19:46] <nats`> aprs map exist but not more generalist map
[19:46] <DL1SGP1> what kind of setup are you testing nats`?
[19:47] <nats`> for the moment a FT790-r and a moxon
[19:47] <DL1SGP1> ah so you need a transmitter to test you ant :)
[19:47] <mfa298> there's a similar thing to "$" that's only for single characters (we talked about it earlier)
[19:47] <nats`> yep DL1SGP1 only rx :)
[19:48] <DL1SGP1> where in France are you?
[19:49] <nats`> south of paris :)
[19:49] <DL1SGP1> does it have to be RTTY or do you wanna test the reception quality in general?
[19:49] <nats`> http://www.radioamateur.org/relais/
[19:49] <nats`> maybe I found my happiness
[19:49] M6GTG_Andrew (~kvirc@cpc19-nwrk4-2-0-cust202.12-1.cable.virginmedia.com) joined #highaltitude.
[19:49] <nats`> in general but RTTY or digital mode allow to be sure :)
[19:50] <DL1SGP1> else I would have tried if there was some echolink repeater nearby and have made use of that to get at least sorta kinda a signal out for you
[19:51] <nats`> echolink ?
[19:52] <DL1SGP1> it is an amateur radio network of repeaters connected through the internet, so if I was sitting on mallorca and wanted to dial home I would access an entry repeater on the island of mallorca, use a dtmf code to identify the place I want to go to
[19:52] <DL1SGP1> and then the connection is established via internet
[19:52] <nats`> ohh oky
[19:53] <DL1SGP1> like this I can call through some repeater anywhere in the world. there is even a software so I would not forcefully need to use a radio as long as I got internet
[19:53] <Geoff-G8DHE> think Skype connected to radios ;-)
[19:53] KD8ATF (~KD8ATF@mobile-198-228-234-118.mycingular.net) joined #highaltitude.
[19:53] <nats`> yep but is it really legal
[19:54] <Geoff-G8DHE> If you have a AR license
[19:54] <DL1SGP1> indeed
[19:54] <nats`> so you emit with your ID on a station abroad ?
[19:54] <DL1SGP1> yes
[19:54] <nats`> you are considered as mobile or ?
[19:55] <DL1SGP1> no :)
[19:55] <DL1SGP1> I would be mobile if I did it from my car. portable if I did it while being at the beach but not moving, as long as I do it from my shack I am non of the two
[19:56] <nats`> and so you add the country station prefix ?
[19:56] <nats`> because physically you're on a coutry but emitting from an other
[19:56] <DL1SGP1> no. I just use my standard callsign without adding a prefix, but it is good practice to add "via Echolink" to the call
[19:57] <DL1SGP1> often the repeater even announces you on air like transmitting something as "DL1SGP has connected"
[19:57] <nats`> oky :)
[19:57] <nats`> that's fun
[19:58] <DL1SGP1> It keeps my phone bill low :) permits me to stay in touch with my best friends in USA where-ever I am
[19:59] <nats`> without skype spying on you :D
[20:00] <DL1SGP1> I would not say so
[20:00] <Geoff-G8DHE> No encryption and open path either end so all public ;-)
[20:00] <nats`> yep so no spying :D
[20:00] <nats`> like iof everyone put his facebook profil to full public facebook is dead :D
[20:00] <DL1SGP1> it would be a licence violation if we used encryption on amateur radio to communicate

[21:30] <Gaz_2> Thanks! No big queries right now - just finding where the knowledge is! We've a team of about 8 people in our company planning a joint launch with an attached charity. None of us done a launch before. I won't embarrass myself with newbie questions til I've read the wiki!!
[21:32] <Upu> yeah have a look round read other peoples blocks
[21:32] <Upu> blogs even
[21:33] <Upu> don't use a GSM Tracker
[21:33] <mfa298> well there are plenty of knowledgeable people around
[21:33] <chrisstubbs> or an 808 camera
[21:33] <Upu> SPOT trackers can also suck
[21:33] <Ramm25> nats` For the construction of peredatchka need an amplifier from the phone SENAO or ready radio BAOFENG
[21:33] <Gaz_2> (Frantically taking notes!!)
[21:33] <nats`> Ramm25 the lna will not be the problem I already did some with dual gate mosfet
[21:33] <mfa298> and if you're close to anyone launching you may be able to go along and find out how some of it works
[21:33] <nats`> I love DGate fet

[21:33] <nats`> more an antenna problem :)
[21:34] <Ramm25> For the construction of transmitter need an amplifier from the phone SENAO or ready radio BAOFENG
[21:34] <nats`> ohh I don't want to do a transmitter
[21:34] <DL1SGP1> nats`: uhfsatcomm site has some nice antenna plans :)
[21:34] <nats`> not sure to be safe in france to do that :)
[21:34] <Gaz_2> I'm in sunny Scotland - not found anyone launching near yet - but perhaps you know better?
[21:35] <nats`> DL1SGP1 I suck at doing antenna I screwed so many yagi :p
[21:35] <Ramm25> nats` dont be afraid)))
[21:35] <nats`> I'm not a good metal worker :D
[21:35] <mfa298> not so many in scotland. I think there was one a few months back
[21:35] <DL1SGP1> well if you screw a jagi you get close to something like a helix :)
[21:36] <DL1SGP1> yagi even
[21:36] <Gaz_2> Scottish weather strikes again! Lol
[21:36] <Upu> there has been a launch or two in Scotland Gaz_2 but not sure who they were
[21:36] <Ramm25> my friend use 5 el yagi for transmitt, it's work
[21:36] <nats`> I see some really narrow band spike sometime in the 255MHz area but don't hear anything
[21:38] <Gaz_2> Good to know - I'll do some more searching

[21:38] <Ramm25> nats`, how you calibrate your RTL?
[21:38] <OH7HJ> What GPS types you use for high alt balloons? I guess standard groung GPS's can not show high altitudes?
[21:39] <mfa298> UBlox
[21:39] <nats`> I don't do calibration
[21:39] <Ramm25> are you use sharsdr?

[21:42] <Upu> Willdude123 because storage costs money
[21:43] <nats`> uhhmm I have the offset in head :)
[21:43] <nats`> I use the AM freq of the airport near me to have it
[21:43] <mfa298> Willdude123: there's not many around. mostly beacause storage is a pain in virtualisation
[21:43] <mfa298> disks are generally slow

[21:44] <Willdude123> But 500gb O.O
[21:44] <nats`> I saw that
[21:44] <mfa298> best place for storage is probably looking at something like the amazon offerings
[21:44] <arko> these n9var guys are flying right over the grand canyon
[21:44] <Willdude123> Oh sold out. :)
[21:44] <arko> i should talk to these guys
[21:45] <Willdude123> mfa298, never looked into amazon cloud stuff

[21:46] <mfa298> then again I probably wouldn't put the words SATA and server together either for preference.
