[00:01] <juxta> hey rjharrison
[00:02] <juxta> how's it going?
[00:02] <rjharrison> Cool i'v been sending icarus around in circles http://robertharrison.org/tracker/
[00:02] <rjharrison> Having a huge over haul of the code at the moment!
[00:03] <juxta> hehe
[00:03] <juxta> July 30 is launch day?
[00:03] <rjharrison> Yep
[00:03] <rjharrison> ATM but subject to WX
[00:04] <rjharrison> bit too early to declare atm
[00:05] <juxta> yeah
[00:05] <juxta> I hope it goes really well
[00:05] <rjharrison> Cheers
[00:05] <rjharrison> It's getting to the witching hour here

[06:42] <mattltm> Mornin all :)
[06:42] <jcoxon> morning mattltm
[06:43] <mattltm> Hows it going?
[06:43] <jcoxon> mattltm, so i'm moving to kent in a week and a bit...
[06:43] <mattltm> Very cool, whee abouts?
[06:43] <jcoxon> canterbury
[06:43] <jcoxon> near the hospital
[06:43] <mattltm> Nice.
[06:44] <mattltm> You could come and join our hackspace :)
[06:44] <jcoxon> might well do
[06:44] <mattltm> the bargin price of £5 per month :)
[06:44] <jcoxon> the canterbury attempts seem to have failed...
[06:45] <mattltm> Yes, and its a shame. I was talking to a few people (with me official hat on) about trying to fine them some free space but no one wants to give them any :(
[06:47] <jcoxon> its not easy to organise
[06:47] <mattltm> lol. Tell me about it!
[06:47] <mattltm> Getting our one off the ground has been, and still is, very hard.
[06:48] <jcoxon> you having weekly meetings then?
[06:48] <mattltm> We was having them but it was getting out of hand. The idea was to set up a group to run the space but all they ended up doing is arguing and not actualy using the space.
[06:49] <jcoxon> oh
[06:50] <mattltm> So I steped in and asserted my authority (again, with my official hat on).
[06:51] <mattltm> So I make the rules, guided by a stearing group of members that I picked.
[06:51] <jcoxon> haha sounds like a benevolent dictator
[06:51] <mattltm> Until such time that the group is big enough to form its own board and look after itself.
[06:51] <mattltm> Yes. I am.
[06:51] <mattltm> :)
[06:52] <jcoxon> perhaps you need a hackspace project
[06:52] <jcoxon> to pull everyone together
[06:52] <mattltm> But, having said that, It is my profesional ass on the line if it dosen't work. :(
[06:53] <mattltm> I had to beg to be allowed to "gift" a £6K room and £3K worth of equipment to a group that didn't exist!
[06:53] <jcoxon> well then the group needs to get using it
[06:53] <mattltm> Since I pulled the reigns in, we now have 6 colabrative projects going on :)
[06:53] <jcoxon> oh cool
[06:54] <jcoxon> website?
[06:54] <mattltm> www.icmp.org.uk
[06:54] <jcoxon> so when should i be coming to visit?
[06:54] <mattltm> The space has 8 members so far. We need to spread the word :)
[06:54] <jcoxon> why don't you invite the canterbury guys
[06:54] <mattltm> Got a dilivery of toys comming next week...
[06:55] <mattltm> Yes, we will :)
[06:55] <jcoxon> cool well sign me up
[06:55] <mattltm> Yay! another normal person! :)
[06:55] <mattltm> Not
[06:55] <mattltm> lol
[06:55] <mattltm> Thats not what I ment to say!
[06:55] <jcoxon> i hold down a normal job
[06:55] <jcoxon> i reckon i'm nearly normal :-p
[06:56] <mattltm> Should have said, Not that most of our guys arn't normal.
[06:56] <mattltm> Hit the enter key!
[06:57] <mattltm> Well, feel free to sign up to the website/forums and say hello :0
[06:58] <mattltm> also #icmp
[06:59] <jcoxon> okeydokey
[06:59] <jcoxon> so is there a 'meeting' day?
[07:00] <mattltm> Let me know when you plan to come up for the first time and i'll treat you to lunch at the Airport cafe and introduce you to the airport manager :)
[07:01] <mattltm> Thursday nights seems to be the main evening.
[07:01] <jcoxon> :-)
[07:01] <jcoxon> okay cool
[07:01] <jcoxon> well the next 3 days i'm going to be back and forth
[07:01] <jcoxon> mon/tues/weds
[07:01] <mattltm> I will put an open night once per month and an open Saturday too once per month on the website.
[07:02] <jcoxon> that sounds good
[07:02] <mattltm> Feel free to pop in anytime during the day and say hello. Im there most of the time :)
[07:02] <mattltm> And once you have handed me £5, I will hand you a key :)
[07:02] <jcoxon> :-p
[07:03] <mattltm> so you can enjoy 24/7 access :)
[07:03] <jcoxon> hooray
[07:03] <jcoxon> though as its a bit of a trek i don't suspect i'll be there that often!
[07:04] <mattltm> we should be getting an osiliscope, function generator, freqancy counter and a few other nice things this week :)
[07:04] <jcoxon> oh wow
[07:05] <jcoxon> got any helium :-)
[07:05] <jcoxon> ?
[07:05] <mattltm> Notyet :)
[07:06] <jcoxon> was thinking of launching picoatlasIII in the next few days
[07:06] <jcoxon> but i'm just not happy with the hardware
[07:06] <mattltm> whats up with it?
[07:06] <jcoxon> its just messy
[07:07] <mattltm> Wrap it in duck tape. It will be fine :)
[07:07] <jcoxon> nah i'll wait a bit - best do the move first
[07:08] <mattltm> Good plan.
[07:08] <mattltm> hows your buoy comming?
[07:09] <jcoxon> yeah thats okay - need to convert it to stripboard
[07:09] <jcoxon> then i think i'll be ready to roll
[07:09] <mattltm> cool.
[07:09] <jcoxon> won't take too long
[07:09] <mattltm> Where are you going to launch it?
[07:09] <jcoxon> well i was going for worthing pier
[07:09] <jcoxon> but thats not going to happen
[07:10] <mattltm> I could probbly get it dropped out at sea in Broadstairs if you like.
[07:10] <mattltm> My brother drives the safety boat for the local sailing club.
[07:11] <jcoxon> might be an idea
[07:11] <mattltm> He could take it x hundred meters out for you.
[07:11] <jcoxon> yeah it would have to be quite close
[07:11] <jcoxon> or we could map some of the waterways around medway
[07:11] <jcoxon> somewhere comms are going to keep connected
[07:12] <mattltm> That sounds interesting. I have access to an open canoe here :)
[07:12] <mattltm> My one is going to be moored in the medway to start with.
[07:12] <mattltm> Just working on borrowing a fixed mooring :)
[07:12] <jcoxon> haha
[07:12] <jcoxon> i had a look at your wiki
[07:12] <jcoxon> looks good
[07:13] <mattltm> that statbuoy one?
[07:13] <jcoxon> yup
[07:13] <mattltm> lol. Yes, I now have minions working on it too :)
[07:13] <jcoxon> haha
[07:13] <jcoxon> these buoys are going to be fun
[07:14] <mattltm> V1 is going to be using a gsm phone to text data.
[07:14] <jcoxon> you going to put a load of batteries in there?
[07:14] <mattltm> V2 will read salinity and test solar charging
[07:14] <jcoxon> sounds good
[07:14] <mattltm> V3 will use a sat modem to send data
[07:14] <jcoxon> not tempted by aprs?
[07:14] <mattltm> and V4 will be set free into the wild :)
[07:15] <jcoxon> perhaps i'm releasing mine too early!
[07:15] <mattltm> I did think about playing with APRS but thats not going to be much use in the middle of the atlantic!
[07:15] <jcoxon> true
[07:15] <jcoxon> spot would do the job
[07:15] <jcoxon> short messages
[07:15] <jcoxon> and we can customise them...
[07:15] <mattltm> Thats what I was thinking :)
[07:16] <mattltm> Yes. I think V1 will be ready to test by the 1st September :)
[07:16] <jcoxon> great
[07:17] <jcoxon> look forward to it
[07:17] <mattltm> After that, the other versions should be quicker :)
[07:17] <mattltm> The bouy is significantly bigger that yours or fsphil's though!
[07:17] <jcoxon> well thats okay
[07:17] <jcoxon> there is a lot of sea
[07:17] <mattltm> lol
[07:18] <mattltm> ok, question...
[07:19] <mattltm> Cheepest hardware that has ethernet and a full serial port that can run linux?
[07:19] <jcoxon> well...
[07:19] <jcoxon> a linksys router is an option
[07:19] <jcoxon> running open-wrt
[07:19] <mattltm> Does it have full serial?
[07:19] <jcoxon> with cts etc?
[07:19] <jcoxon> or just rx/tx/gnd
[07:20] <mattltm> with DCD
[07:20] <jcoxon> and ttl or rs232?
[07:20] <mattltm> rs232
[07:20] <jcoxon> nah they won't have that
[07:20] <mattltm> I want to build a stratum 1 ntp server
[07:20] <jcoxon> well you might be better off findin a ethernet/usb linux board and then add a usb-serial convertor
[07:21] <mattltm> No good. The timing issues with usb mess up the pps signal from the gps.
[07:21] <mattltm> Has to be propper serial :(
[07:22] <jcoxon> hmmm most linux boards will be ttl voltages
[07:22] <mattltm> May work on ttl
[07:22] <mattltm> In fact, I cant se why it shouldnt
[07:22] <jcoxon> http://wiki.openwrt.org/toh/start
[07:24] <mattltm> the basic idea is to connect the gps via serial and use the nema message to get year, month, day and time then connect the Pulse Per Seccond signal from the gps to the DCD pin on serial to get the exact start of the second. You end up with a clock acurate to nanoseconds :)
[07:24] <jcoxon> surely a micro would be good in this case
[07:24] <mattltm> So long as it had serial :)
[07:25] <mattltm> http://www.ubnt.com/airrouter
[07:25] <jcoxon> how about interrupts
[07:25] <mattltm> I can pick those up for sub £40
[07:25] <mattltm> Has serial, so I her.
[07:25] <mattltm> *hear
[07:26] <mattltm> Maybe I could use a GPIO pin for the PPS?
[07:26] <jcoxon> yeah
[07:26] <jcoxon> http://wiki.openwrt.org/toh/linksys/wrt54g
[07:26] <jcoxon> these are good
[07:26] <jcoxon> 2 serial ports
[07:26] <jcoxon> ethernet
[07:26] <mattltm> Got a few in the cupboard :)
[07:26] Jasperw (~jasperw@62-2-134-218.static.cablecom.ch) left irc: Ping timeout: 276 seconds
[07:27] <jcoxon> i build a payload with one before
[07:27] <mattltm> 2 serial ports?
[07:27] <jcoxon> built*
[07:27] <jcoxon> WRT54G/S/L has 2 internal serial ports
[07:28] <mattltm> ohh..
[07:28] <mattltm> that could work.
[07:29] <mattltm> I think I may go the micro route for the first one though :)
[07:29] <jcoxon> the only thing is that you'd need to use a kernel driver for the gpio
[07:29] <jcoxon> as it wouldn't be quick enough
[07:29] <mattltm> true.
[07:29] <jcoxon> yeah i think an avr would be far more efficient
[07:29] <mattltm> Ok, so good micro with etherned and full serial
[07:30] <jcoxon> well you don't need full serial
[07:30] <jcoxon> you could have a normal i/o pin as an interrupt
[07:30] <jcoxon> would act like DCD
[07:30] <jcoxon> right time to get ready for work - another 12hr shift to face
[07:30] <mattltm> yup.
[07:30] <mattltm> Oh. Ouch.
[07:31] <jcoxon> third day in a row
[07:31] <jcoxon> its beginning to hurt
[07:31] <mattltm> Well good luck. And thanks :)

[09:10] <futurity> Morning. Is the launch already in progress?
[09:13] <mattltm> You mean the Ava launch?
[09:14] <futurity> The one in Yorkshire I think?
[09:15] <mattltm> If its AVA, Upu's launch then it was called off yesterday.
[09:15] <Darkside> and nigey's launch was called off too
[09:15] <Darkside> as he couldn't get gas
[09:15] <mattltm> I think thats the one :(
[09:15] <Darkside> also FFS, i cant top-up my sim card
[09:15] <Darkside> it needs a UK postcode
[09:15] <Darkside> this is bullshit
[09:16] <Darkside> i cant use my credit card
[09:16] <Upu> called off sorry
[09:18] <futurity> Thanks for the update. I'll hopefully track the next time :)
[09:19] <number10> morning chaps - was looking for NTX 434.075 - farnell only do the 434.650 and radiometrix dont seem to have it online shop - I suppose I could phone them - anyone know where to buy online in UK (google not showing anything)
[09:19] <mattltm> Call radiometrix.
[09:19] <mattltm> They are very nice :)
[09:20] <number10> ok will do - I bought some Bim2 years ago for a project - so I know they are not scary ;-)
[09:20] <mattltm> Well, the woman who answers the phone (Rose?) can get a bit frisky :p
[09:21] <number10> lol...is there a reason why you all use the .075?
[09:21] <mattltm> less interferance
[09:21] <number10> ahh... cheers
[09:21] <mattltm> There are also some ham 70cm repeater outputs on .650
[09:22] <number10> I have a lot to learn - but no rush
[09:23] <mattltm> is this working for anyone? >>> http://www.mattltm.co.uk/chicken-cam/
[09:24] <number10> yep
[09:24] <mattltm> ta ;)
[09:25] <number10> i can see a cheap multimeter ;)
[09:25] <mattltm> Yay!
[09:25] <mattltm> and a .075 ntx2 :)
[09:25] <number10> and that ntx2 u were going to send me
[09:26] <mattltm> lol.
[09:26] <number10> i'll grab it
[09:26] <mattltm> Saying that. I may have a spare....
[09:26] <mattltm> Yup.
[09:26] <number10> lol ... how could u do that to me!
[09:27] <mattltm> you want it?
[09:28] <number10> Its OK, thats kind of you to offer but I'll give radiometrix an call to start - I dont whant to start scrounging bits this early in the game
[09:28] <mattltm> lol.

[09:29] <number10> does anyone use the highr power mudules for locating once landed?

[09:30] <number10> I thought there were some licsence free 500mw for asset tracking..
[09:30] <mattltm> maybe..
[09:31] <mattltm> http://stakeholders.ofcom.org.uk/binaries/spectrum/spectrum-policy-area/spectrum-management/research-guidelines-tech-info/interface-requirements/IR2030final.pdf
[09:31] <number10> TX3H
[09:32] <mattltm> 869.40 can be used @ 500mw but only with a 10% duty cycle.
[09:33] <mattltm> But the highre freq also means less range compared to 434
[09:35] <number10> the other thing I was thinking about was this http://www.amazon.co.uk/Mini-Global-Tracker-GPRS-connection/dp/B003XDQUQE/ref=sr_1_2?ie=UTF8&qid=1311500081&sr=8-2
[09:35] <number10> for when it lands
[09:35] <mattltm> would loose gprs signal
[09:35] <mattltm> No good for live tracking
[09:36] <number10> Not for that, but to locate it on the ground -
[09:36] <mattltm> Ahh, it would be fine for that so long as you landed in a spot with good coverage.
[09:37] <number10> and that may not always be the case
[09:40] <number10> thanks for the info matt
[09:45] <fsphil> mattltm, at 869mhz the 500mw would make up for the loss of distance due to frequency
[09:46] <fsphil> but considering the range of the 10mw module, I'm not sure it's worth it
[09:47] <fsphil> and on the ground, 869mhz would be affected more by the terrain
[09:47] <mattltm> Yup, its for a recovery beacon.
[09:48] <fsphil> aprs wouldn't be much better, with it using 1200 baud + FM modulation its range would probably be even less
[09:49] <mattltm> Yup.
[09:49] <mattltm> I would go with gprs/gsm for a backup recovery device.
[09:49] <fsphil> agreed
[09:49] <mattltm> I would guess the in most cases the main tx would still be running anyway.
[09:50] <number10> that one on amazon - you make a call to it and it sends you a txt of location
[09:51] <mattltm> That sounds like it would be ok.
[09:51] <mattltm> Didnt a recent launch have somthing like that on?
[09:53] <number10> I dont know - I have only started to get interested in the HAB
[09:58] <fsphil> the scottish launches had a gsm backup
[09:58] <fsphil> which they needed, twice :)
[09:58] <mattltm> and the one where the coords got messed up?

[15:16] <fsphil> back now Upu
[15:16] <Upu> hi fsphil
[15:16] <Upu> its ok I was just wondering if you had any raw NMEA data with time stamps in tact
[15:17] <Upu> but its ok I think I've fixed it
[15:17] <Upu> trying to get the payload to know its true vertical rate based on time
[15:17] <Upu> see if I can detect the following ascent, decent, burst, float and leak
[15:18] <fsphil> aah, good idea
[15:18] <Upu> trouble is my times are crap so the data isn't working
[15:18] <fsphil> nah I just have the fake data, I could get a dump from a real gps device but it wouldn't be moving upwards
[15:19] <Upu> I can fake the alititude
[15:19] <Upu> or at least copy it from a live launch
[15:20] <daveake> I can get you the ascent, burst and descent data from my logs.
[15:20] <daveake> Can't do landing as I lost that bit
[15:20] <Upu> raw NMEA ?

[15:55] <Darkside> made a potentially fatal mistake in component selection

[15:58] <SpeedEvil> What crystal
[15:58] <Darkside> the datasheed doesn't give enough information
[15:58] <SpeedEvil> What size is the crystal?
[15:58] <Darkside> so, i've got the option on the PCB for either the crystal i wanted to use, or a monolithic resonator
[15:58] <Darkside> its an ABM7
[15:58] <SpeedEvil> What size is that
[15:58] <SpeedEvil> I forget

[16:40] <RocketBoy> a tester like that is almost essentual when the code gets complex - I have lots of interacting state machines in my code - to turn video cameras on/off, predict landing spots compare against UK outlines ... - so the tester code generates NMEA from KML files and spits it out to the PC serial port where I plug it in where the GPS would go

[21:22] <kristianpaul> and at night by infrared radiation from Earth. Although small, the lift generated by the greenhouse effect then suffices to stabilize the balloon about 20 km. Capable of carrying up to 50 kg payload, the aerostat has the originality to oscillate continuously at 2 altitudes for 2 to 3 weeks. It is particularly interesting to study the stratosphere.

[22:39] <nickolai> i have the transmitter hooked up to a chipkit uno32 board and at the moment it's just transmitting the sentence "Dayton\n" non-stop
[22:40] <nickolai> i checked the baud rates and sound settings and such, and rewired the breadboard to reduce interference, but can't seem to figure out what's wrong

[22:41] <SpeedEvil> Fo you have a voltage divider on the input of the ntx2
[22:41] <SpeedEvil> Or are you running it direct from the GPIO

[22:55] <nickolai> hm, it still looks funny, but i'll double-check it with an arduino board to see if maybe the uno32 isn't handling the code as expected

[23:41] <Dan-K2VOL> there's some sort of import command
[23:41] <Dan-K2VOL> it can do it
[23:41] <nickolai> yea fsphil was just able to decode my file but i can't find whatever button you have to press to get it to accept an audio file
[23:41] <Randomskk> under file
[23:42] <Randomskk> audio > playback
[23:42] <nickolai> i tried that, and fldigi crashes
[23:42] <Randomskk> :3
[23:42] <nickolai> are you on linux?
[23:42] <Randomskk> os x right now, but normally yes, and normally it does work
[23:43] <fsphil> I'm on linux, and it has the option to record from the audio output
[23:43] <fsphil> so I just played the ogg in another file
[23:43] <Randomskk> oh, yea, it'l need to be WAV
[23:43] <fsphil> fldigi can read wav files directly (mono, 9000Hz, 16-bits)
[23:43] <nickolai> grr, stupid conversions
[23:43] <fsphil> (also FLAC on certain builds)
[23:44] Action: hibby suggests 24 bit would be better now we're in the "modern age"
[23:44] <hibby> :p
[23:44] <hibby> fldigi build on arm?
[23:44] <fsphil> nah, 32-bit .. it's the only way to be sure
[23:44] <Randomskk> 50 baud RTTY
[23:44] <Randomskk> "modern age"
[23:44] <Randomskk> really
[23:44] <hibby> Randomskk: I think you're missing the 50 baut RTTY FROM SPACE part
[23:45] <hibby> and space==modern age
[23:45] <Randomskk> you could use sodding 1-bit WAV at 100Hz and still not lose any data
[23:45] <hibby> we need cinema sound, or things won't go well...
[23:45] <hibby> :p
[23:45] <Randomskk> pfft, real modern space streams HD video from orbit :P
[23:45] <hibby> hahah
[23:46] <fsphil> yea, lunar orbit
[23:46] <hibby> wait till we eventually get UKube up
[23:46] <Randomskk> haha I love it when I get an email, like three devices make gentle chimes all over my room
[23:46] <fsphil> Ithe last jaxa lunar orbiter had an HD camera)
[23:46] <Randomskk> it's like having wind chimes that get blown by the digital stream of new information
[23:46] <Randomskk> surprisingly in-sync given as one is over my wifi, another on my wired and a third over the cellular network
[23:46] <Randomskk> hurrah for push notification I guess
[23:47] <fsphil> "You've got mail .... it's not spam!"
[23:47] <hibby> what day is it?
[23:47] <fsphil> </futurama>
[23:47] <nickolai> dammit, i can't even decode my own file
[23:47] <fsphil> hibby, holiday! woo-hoo!
[23:47] <nickolai> for some reason the shift is closer to 170 than 425
[23:47] <hibby> fsphil: not in yankland
[23:47] <fsphil> also, monday
[23:47] <fsphil> nickolai, yea the sample isn't 9000hz
[23:48] <nickolai> i had just re-recorder a sample in .wav
[23:48] <fsphil> you need to change the samplerate too
[23:48] <Randomskk> nickolai: listen to the WAV in VLC, vs the OGG
[23:48] <fsphil> fldigi is very stupid
[23:48] <Randomskk> see if they sound different
[23:48] <Randomskk> or to be honest
[23:48] <Randomskk> play the OGG very loud next to your microphone >_>
[23:48] <nickolai> they sound the same
[23:48] <Randomskk> right, sleep time, work tomorrow :3
[23:50] <hibby> y'know what bothers me about engadget editorials? They're so thin on actual opinion and analysis
[23:50] <hibby> it's a bit like "write 800 words, no more!"
[23:50] <nickolai> ok, got it working now. i used the audio cable to connect the computer's audio output to the audio input and played it in vlc :)
[23:51] <nickolai> and pressing rv did the trick
[23:51] <nickolai> now let's see if the radio works
[23:52] <fsphil> sorry, the wav file needs to be 8000hz not 9000hz
[23:52] <fsphil> nickolai, http://sanslogic.co.uk/files/audiosample.wav
[23:54] <nickolai> thanks fsphil, i got it working
[23:54] <nickolai> i think upu's diagram is messed up because it only worked for me when i pressed the rv button
[23:55] <fsphil> is your radio in USB mode?
[23:55] <nickolai> lsb
[23:56] <fsphil> there's your problem :)
[23:56] <nickolai> how so? it was working on lsb
[23:56] <fsphil> LSB inverts the frequencies
[23:57] <fsphil> ideally you want it to work in USB mode without the Rv button being ticked
[23:58] <fsphil> for no technical reason, just seems to be the accepted standard
