[04:19] <nickolai> hi fergusnoble
[04:19] <nickolai> i'm ok on code, but it's hardware interface I'm having trouble with
[04:19] <nickolai> i bought the ribbon cable but it seems to be too big to fit on the pins (correct spacing and all, it's just wider than the hole on the lassen)
[04:19] <fergusnoble> ok, there are eagle schematics for that board on the svn
[04:20] <nickolai> i was wondering if anyone else bought the ribbon cable and if they had a similar issue
[04:20] <nickolai> i don't want to make a pcb, i'd prefer to use the ribbon just for simplicity
[04:21] <nickolai> i think i can just chop off the sides and stick it in, but i'd first like to know what others have done
[04:21] <nickolai> i take it you made a pcb?
[04:21] <fergusnoble> oh we made a pcb with the smt connector
[04:21] <fergusnoble> yeah
[04:21] <fergusnoble> the ribbon is from sparkfun?
[04:22] <nickolai> no, it's from a company called avnet
[04:23] <fergusnoble> ok, got a link with a picture of it?
[04:23] <nickolai> lemme see...
[04:24] <nickolai> lassen iq book page 22
[04:24] <nickolai> http://gpsd.berlios.de/vendor-docs/trimble/trimble-lassen-iq.pdf
[04:25] <fergusnoble> ok, I see it
[04:26] <fergusnoble> the black plastic part is too wide to fit thought the hole in the can?
[04:26] <nickolai> yea... tho looking at their picture it's odd that it sticks out a bit
[04:26] <fergusnoble> hmm
[04:27] <fergusnoble> sometimes the top cover of the connector is held on by clips on the side so you would have to be careful not to cut those off
[04:27] <fergusnoble> but it should be ok
[04:27] <nickolai> i got like 4 cable in anticipation something would go wrong so i have some room to experiment :)
[04:28] <nickolai> i would just prefer to keep that experimentation to a minimum, since 4 is a very finite number....
[04:28] <nickolai> and the lead time on the cable is like a week
[04:29] <nickolai> how did you make the pcb, did you order one or use a toner transfer method?
[04:35] <fergusnoble> it was ordered from olimex I believe

[04:50] <nickolai> i just went and clipped off the edges. it seems to fit but on of the connectors is now partially exposed. It looks like it'll work but I'm dissappointed that i had to do it like that. I was hoping for plug-n-play
[04:51] <nickolai> i haven't found a gps w/o altitude restrictions that i can implement without a pcb. any suggestions? I've tried garmin gps 18x lvc, but that one actually needs an inverter to work so, no cigar...
[04:53] <fergusnoble> hmm& I think any uBlox chipset based module will work
[04:53] <fergusnoble> depends on how much kludging you are willing to accept
[04:56] <nickolai> meh.... not too much...
[04:56] <nickolai> i keep hearing about ublox, i'll have to investigate them
[04:57] <nickolai> i now see on this project they had a similar issue to the one i'm facing - and they decided to bend the board instead of clipping the connector: http://alienproject.wordpress.com/2009/04/15/workshop-15-picture-post/3-gps-processor-bottom/
[04:57] <nickolai> er, bend the can
[04:58] zachjacobs (~zachjacob@74-137-89-16.dhcp.insightbb.com) left irc: Remote host closed the connection
[05:00] <fergusnoble> maybe thats neater
[05:00] <fergusnoble> I dont know
[05:00] <fergusnoble> yeah uBlox is a really nice chipset
[05:00] <fergusnoble> worth looking at
[05:00] <fergusnoble> but the lassen always worked great for me for HAB though
[05:05] <nickolai> yea, this is my 3rd gps, after inventek and garmin
[05:05] <nickolai> inventek worked well for a while, but i just made a toner transfer pcb, and it worked poorly
[05:07] <nickolai> anyway, nice chatting with ouy fergusnoble, i'm off to bed - it's past 1am here in indiana :)
[05:08] <nickolai> have a good day/night

[06:35] <jcoxon> hey Darkside
[06:35] <jcoxon> realised that my fsa03-lp actually has ublox 6 onboard
[06:36] <Darkside> yeah i heard the -lp has the new ones
[06:36] <jcoxon> though it looks like they've discontinued the product
[06:36] <Darkside> heh
[06:36] <Darkside> so no more fsa03s?
[06:36] <jcoxon> i've got 2
[06:37] <Darkside> i mean aren't they selling them anymore
[06:37] <jcoxon> seems like that
[06:37] <Darkside> damn
[06:39] <fsphil> I need to find my box, see if they're 5 or 6s
[06:39] <jcoxon> i'm glad they are 6 - the powersaving is much better

[06:48] <UpuWork> Morning
[06:48] <UpuWork> I'm going to order some of those uBlox 6 chips
[06:48] <UpuWork> if anyones interested
[06:49] <gm> what features are better than ublox5?
[06:49] <UpuWork> when are you shipping the break out boards Darkside ?
[06:49] <UpuWork> Err you can get uBlox 6 :)
[06:49] <UpuWork> uBlox 5 is going EoL early next year according to the supplier
[06:49] <jcoxon> gm, well they are about the same for gettign a fix etc
[06:49] <UpuWork> but power consumption I think is lower
[06:49] <jcoxon> but their power saving is much better
[06:50] <jcoxon> they have more options
[06:50] <UpuWork> wanting any jcoxon ?
[06:50] <jcoxon> in theory once its got a lock it can go into a tracking mode with an average current of 10mA
[06:50] <jcoxon> and still give you position updates
[06:50] <jcoxon> UpuWork, how much?
[06:51] <UpuWork> £18.63 each ex VAT
[06:51] <UpuWork> I'll bring them to the conference so no delivery
[06:51] <jcoxon> what model?
[06:51] <UpuWork> NEO-6Q-O
[06:51] <UpuWork> See mail I just sent
[06:52] <jcoxon> 3v?
[06:53] <UpuWork> 2.7 - 3.6
[06:53] <UpuWork> Which means I need to redesign
[06:54] <UpuWork> as I'm on 5v atm
[06:54] <jcoxon> yeah i'll take 3
[06:54] <UpuWork> ok
[06:54] <jcoxon> they'll need a regulator
[06:54] <UpuWork> I'll fire a mail round see if anyone else wants some
[06:56] <costyn> UpuWork: sounds interesting yes
[06:56] <Darkside> hmm
[06:56] <Darkside> UpuWork: hey
[06:56] <Darkside> i'm waiting on the antennas
[06:56] <Darkside> but they should be in soon
[06:56] <jcoxon> UpuWork, make it very clear that they are pure chips
[06:56] <Darkside> oh god
[06:56] <Darkside> are they just teh chips?
[06:56] <Darkside> not the modules?
[06:56] <jcoxon> oh i mean modules
[06:56] <Darkside> no wait
[06:56] <jcoxon> that they will need a breakout
[06:56] <jcoxon> don't want people being disappointed
[06:56] <Darkside> and i've fgot the breakouts
[06:57] <Darkside> :-)
[06:57] <Darkside> hell, i'll just release my design
[06:57] <Darkside> and you'll all just have to get hold of the right antennas
[06:57] <UpuWork> can I put that in the mail ?
[06:57] <UpuWork> yeah was going to ask what is the antenna model number and where did you get them ?
[06:57] <Darkside> SL1202RH from Richardson Electronics
[06:57] <UpuWork> thanks
[06:58] <Darkside> the boards are meant to have a little notch in them, but i didn't trust seeedstudio to do it correctly so i didn't put it on the board
[06:58] <Darkside> the antenna fits onto the 0.8mm FR4 nicelt anyway
[06:58] <jcoxon> Darkside, oh they do the notch
[06:58] <jcoxon> i got it for my fsa03 breakouts
[06:59] <Darkside> ooh
[06:59] <Darkside> ill do that on the next lot i order then
[06:59] <Darkside> do you just put it on the silkscreen overlay?
[06:59] <Darkside> or what layer did you put it on?
[06:59] <jcoxon> Darkside, i don't remember
[06:59] <Darkside> ok
[06:59] <jcoxon> i was using eagle
[06:59] <Darkside> my antennas are in hong kong
[06:59] <Darkside> and i have 20 antennas on the way
[07:00] <griffonbot> Received email: Anthony Stirk "[UKHAS] uBlox NEO-6Q"
[07:00] <UpuWork> where did you get them from ?
[07:00] <UpuWork> you have to release break out design now Darkside as I just put it in a mail :)

[07:00] <Darkside> ack
[07:00] <Darkside> sure, i'll upload the ALTIUM DESIGNER Files now
[07:00] <Darkside> that none of you will be able to read :P
[07:00] <UpuWork> you'll need to do an Eagle version
[07:00] <Darkside> bahahahah
[07:00] <UpuWork> lolol

[07:01] <UpuWork> nah just product overview 752kb
[07:01] <Darkside> ugh
[07:01] <UpuWork> lovely number10
[07:02] <costyn> Darkside: are you going to be doing the other GPS's inlc breakouts that you made the document for?
[07:02] <Darkside> number10: UpuWork cheaper at richardson
[07:02] <Darkside> richardson charge $6.50 per antenna
[07:02] <Darkside> oh wait
[07:02] <Darkside> with 15 it might be comparable
[07:03] <UpuWork> http://www.rell.com/pages/Product-Details.aspx?productId=932896
[07:03] <number10> the richardson site dont show tha case for some reason http://www.rell.com/pages/Product-Details.aspx?productId=922313
[07:03] <Darkside> nope, still cheaper from richardson
[07:03] <Darkside> ack rells site isnt loading for me
[07:03] <UpuWork> £4.47
[07:03] <UpuWork> ex delivery from Richardson
[07:03] <Darkside> stupid australian internet
[07:04] <Darkside> yeah
[07:04] <UpuWork> ok cool
[07:04] <Darkside> they charged me about AUD$35 for fast DHL delivery
[07:04] <UpuWork> I'll take a break out pls DanielRichman :)
[07:04] <UpuWork> err
[07:04] <UpuWork> Darkside
[07:04] <Darkside> fuuuu
[07:04] <Darkside> i have 9 PCBs here
[07:04] <UpuWork> chop chop then I have a payload to build, broke the last one :)
[07:04] <Darkside> why don't i just put the gerbers online and you can order some from seeedstudio :P
[07:04] <Darkside> oh wait
[07:04] <Darkside> you need to put the order number on the PCB somewhere
[07:05] <UpuWork> well yours are prebuilt and tested which is always a bonus
[07:05] <Darkside> uuuuurgh
[07:06] <Darkside> well, when i get these antennas i'll make them up..
[07:06] <Darkside> should be tomorrow or the day after
[07:06] <UpuWork> lovely
[07:06] <UpuWork> cheers for that
[07:06] <UpuWork> now we just need to work out how to get the break out into Eagle
[07:06] <Darkside> haha
[07:06] <Darkside> not happening
[07:06] <UpuWork> and I need to design the Eagle package
[07:06] <Darkside> i don'tknow of a way to import altium sruffs into eagle
[07:06] <Darkside> stuffs*
[07:07] <Darkside> or vice versa
[07:07] <Darkside> just download altium designer :P
[07:07] <Darkside> its not hard to find
[07:07] <UpuWork> will people accept designs done in hooky copies ?
[07:08] <UpuWork> I know Eagle you can't
[07:08] <Darkside> well seeedstudio just wants the gerbers
[07:08] <Darkside> and those are CAD software independent
[07:09] <UpuWork> I'll see how I get on with Eagle
[07:09] <Darkside> also pcbtrain didn't notive that i was sending them altium files made with a bodgy copy of altium :P
[07:09] <UpuWork> lol
[07:09] <Darkside> and this was the TOPCAT PCB mind you
[07:09] <Darkside> >_>
[07:11] <Darkside> ahhhhhh, i put the cutout into the mechanical 1 layer
[07:11] <fsphil> UpuWork, stick me down for 3 too
[07:11] <Darkside> it needs to be in the silkscreen layer for seeedstudio to cut it out
[07:12] <Darkside> y;know, i could do a seeedstudio order and just get it shipped to one of you guys
[07:13] <UpuWork> ok fsphil
[07:13] <jcoxon> as there isn't really a commercial ublox 6 module avaliable this could be a small business oppurtunity
[07:13] <fsphil> I gotta start on this SMD fun sometime :)
[07:15] <UpuWork> well sure its just a small step to link one of our trackers to a GSM/GPRS modem
[07:15] <UpuWork> and you have a vehicle tracker
[07:15] <fsphil> it's nearly cheaper to buy a separate unit. there are no cheap gsm-modules
[07:15] <UpuWork> Anyway mail me your orders, I really need to do some real work today :)
[07:16] <Darkside> oh yeah guys
[07:16] <Darkside> the ublox module is the HARDEST thing onthe micronut board to solder
[07:16] <Darkside> dead serious
[07:16] <Darkside> its a pain in the ass
[07:16] <UpuWork> Darkside make a video :)
[07:16] <Darkside> FUUUUU
[07:16] <Darkside> i guess i could
[07:16] <Darkside> >_>
[07:16] <fsphil> define hard
[07:16] <fsphil> as in, *aaaaah solder you ****'ing thing* hard?
[07:17] <UpuWork> I have a Blackjack solderwerks rework station with a very very small bit, also has a hot air jobbie on it
[07:17] <fsphil> or *ah crap I just broke it* hard?
[07:17] <Darkside> getting the head into the little crooves
[07:17] <Darkside> grooves
[07:17] <Darkside> do not use hot air on the ublox modules
[07:17] <UpuWork> do you glue the comp to the board dirst ?
[07:17] <Darkside> nah
[07:17] <UpuWork> first
[07:17] Wil5on (~Wil5on@ joined #highaltitude.
[07:17] <Darkside> i tack down one pad
[07:17] <Darkside> i'll do up a video
[07:17] <UpuWork> please that would really help
[07:17] <fsphil> no hot air?
[07:17] <Darkside> nope
[07:17] <Darkside> again, i'll video
[07:17] <Darkside> ok, i've added the notch to the pcb
[07:18] <Darkside> oh hang on
[07:18] <Darkside> this isnt the latest version
[07:18] <Darkside> fuuuuu
[07:18] <Darkside> i really need to stick all my pcb designs into a version control repository
[07:18] <Darkside> i moved all the holes so that they lined up with 0.1" spacing
[07:19] <Darkside> so you can bolt them down onto a veroboard easily
[07:19] <fsphil> sneaky
[07:20] <jcoxon> this payload is becoming increasingly complicated
[07:20] <jcoxon> hmmm
[07:20] <Darkside> is everyone fine with just a normal pitch header on the PCB?
[07:20] <jcoxon> always sensible
[07:20] <Darkside> i was considering trying to fit one of those SMD connecotrs like on some of the other modules on there too
[07:21] <jcoxon> nah 0.1 is the key
[07:21] <Darkside> ok
[07:21] <jcoxon> breadboard able for testing
[07:21] <Darkside> and i've set it up so you can use either 4 or 6 pins
[07:21] <jcoxon> easy to make connectors
[07:21] <daveake> +1
[07:21] <Darkside> GND, TX, RX, 3V3, VBATT, 1PPS
[07:21] <Darkside> the last 2 pins are optional
[07:21] <Darkside> but if you don't use VBATT, you need to short 2 pads on the pcb
[07:22] <Darkside> as the ublox module doesnt like having the vbatt pin floating
[07:22] RocketBoy (~steverand@5acfd4f7.bb.sky.com) left irc: Quit: RocketBoy
[07:24] <fsphil> I left the batt pin floating on the fsa03, though it may be doing something else on the board before it gets to the chip
[07:24] <fsphil> can vbatt simply be grounded?
[07:24] <Darkside> yes
[07:24] <Darkside> its what the ublox 6 hardware integration manual says to do
[07:25] <Darkside> i went through that manual extensively to work out what i had to do
[07:31] <fsphil> hah, it's going to cost more to get to london from cardiff than from here
[07:32] <Darkside> haha my blog got 600 visits from hackaday

[07:52] <costyn> what/where is EARS?
[07:52] <jcoxon> costyn, cambridgeshire, uk
[07:53] <costyn> is it like a special location that I see it come by often?
[07:53] <costyn> (and what is it an abbreviation for?)
[07:53] <jcoxon> its a field where there are regular rocket launches
[07:53] <UpuWork> EARS = East Anglia Rocket Society but Steve wants to call it Elsworth now
[07:53] <costyn> aaah ok
[07:53] <jcoxon> UpuWork, fair point really
[07:53] <UpuWork> its a location near Cambridge with a permanent NOTAM for launches
[07:53] <costyn> aah makes sense :)

[11:56] <SpeedEvil> In principle I guess the current architecture could cope with 3 or 4 balloons in teh same spectrum
[11:57] <SpeedEvil> If fldigi could understand multiples coming throuhg the same audio.
[12:01] <daveake> Multiple sound cards and separate copies of dl-fldigi?
[12:02] <daveake> Sorry ... one card and multiple copies
[12:02] <daveake> Brain still not working today
[12:03] <SpeedEvil> I meant one soundcard, one reciever, with multiple payloads in-band
[12:04] <SpeedEvil> And teach fldigi how to decode several streams at once
[12:04] <SpeedEvil> Which sounds like it'd be challenging.
[12:05] <W0OTM> morning
[12:05] <W0OTM> (or eve depending on where you are)
[12:05] <GW8RAK> My £8.50 Canon camera has arrived today :) . Unfortunately no SD card. Do I need a fast one for video recording under CHDK or will any type do?
[12:06] <W0OTM> For those who havnt seen it. iHAB-7 Launch Highlight Video [HD] - http://www.youtube.com/watch?v=lvdi8QoJNoc
[12:06] <daveake> SpeedEvil - Yes, understood now :-). But if 1 copy can't do it, several copies running simultaneously should still work.
[12:06] <SpeedEvil> GW8RAK: More or less any
[12:06] <griffonbot> Received email: Oliver De Peyer "Re: [UKHAS] How may balloons could be tracked simultaneously?"
[12:06] <SpeedEvil> daveake: In principle yes, if the soundcard can be opened multiple times. It would rely on the transmitters being stable to +-100hz or so.
[12:06] <daveake> GW8RAK: Just check what max size the camera can handle.
[12:07] <GW8RAK> Currently RTFM'ing
[12:07] <daveake> SpeedEvil: Yep
[12:08] <SpeedEvil> And of course, doing it that way will desensitise the receiver if the balloons are at noticably different ranges
[12:09] <SpeedEvil> I don't know how much it takes to degrade teh signal - will a +20dB signal have much effect?
[12:09] <GW8RAK> Nothing in the manual on max card size. Will try a few I've got at home
[12:09] <SpeedEvil> How old is it?
[12:09] <SpeedEvil> If it's old enough that 2G may seem big, it might have problems with SDHC cards
[12:09] <daveake> IIRC that one does take SDHC, so he's probably OK
[12:13] <GW8RAK> 2GB has been tested and worked okay apparently. It's about 4 years old I believe
[12:13] <GW8RAK> A460
[12:14] <fsphil> if fldigi could handle more than 4khz bandwidth, using the funcube dongle you could receive many payloads. fldigi can receive multiple rtty streams at a time now
[12:15] <SpeedEvil> Indeed.
[12:15] <fsphil> psk31 would be even better
[12:15] <SpeedEvil> Laurenceb had a poke at it a while back, and IIRC it seemed a mess, and diddn't seem particularly trivial to get to work
[12:15] <SpeedEvil> But psk can't be easily done with the existing modules
[12:15] <fsphil> fldigi seems to work at different sample rates depending on the mode used
[12:16] <fsphil> indeed. I wonder why, is it easier to make an FM module?
[12:16] <SpeedEvil> It's an interesting question on if it can be done at all, which depends on the phase performance of the modules, I guess
[12:16] <SpeedEvil> You can do PSK with FM, quite simply
[12:16] <SpeedEvil> You just FM the carrier for a total time enough at a different frequecy to shift the phase.
[12:18] <SpeedEvil> If it goes +-10KHz, then you have +-3.6 degrees/iusecond tuning, so you need a 50us or so pulse of max or min tune to shift the phase 180 degrees
[12:18] <SpeedEvil> Or something like that
[12:18] <fsphil> have you tried it?
[12:19] <SpeedEvil> This is an argument in principle.
[12:19] <SpeedEvil> The exact performance depends on stuff.
[12:20] <SpeedEvil> For example - how well will the reciever cope if you're 5 degrees off.
[12:20] <SpeedEvil> Plus - PSK31 has no advantage if you can't keep the transmitter stable enough to not bang into others.

[12:21] <fsphil> thinking narrower bandwidth
[12:22] <SpeedEvil> Narrower bandwidth only has a major point if you can use it. If you can put a narrowband filter around it, and avoid co-channel interference that way
[12:22] <SpeedEvil> Or if it greatly reduces the amount of spectrum noise you care about
[12:22] <fsphil> I suppose just using FM and more power would probably still be as good as psk or rtty
[12:22] <SpeedEvil> psk, and rtty are as I understand it more or less similar
[12:23] <SpeedEvil> The only difference is with rtty, you have a little more than twice the bandwidth the signal occupies.
[12:23] <SpeedEvil> (you don't care about the bit in the middle so much)
[12:23] <fsphil> indeed
[12:24] <SpeedEvil> FM works well, but requires a signal margin over anything else in the channel, which PSK and rtty don't
[12:24] <griffonbot> Received email: steamfire@gmail.com "Re: [UKHAS] How may balloons could be tracked simultaneously?"
[12:24] <SpeedEvil> (they only require margin over interfering signals, not just signals in the same passband)
[12:24] <fsphil> why I was thinking of more power. the 500mw modules are bound to have pretty good range
[12:25] <SpeedEvil> Isn't the limit...
[12:25] <SpeedEvil> oh - that's for 433 isn't it
[12:25] <fsphil> 839mhz @ 500mw (10% duty)
[12:25] <fsphil> the frequency will drift but that's not as important for fm
[12:25] <SpeedEvil> Depending also on the backfround noise
[12:25] <SpeedEvil> Where do I remember that number from...
[12:26] <fsphil> true. here at least 869mhz is pretty empty
[12:26] <SpeedEvil> I vaguely recall ~800 is used for RF heating in meatpacking and similar plants
[12:26] <SpeedEvil> Which is the reason for the exempt band.
[12:26] <fsphil> might be worth bringing the fcd up to the hill and see how much noise there is
[12:28] <fsphil> radiometrix claim a range of 5km using their transceiver. wonder how optimistic that is
[12:28] <fsphil> no price either, it may well be more expensive than a gsm tracker

[17:42] <hburger> Hey! Anyone there who can help me with some balloon launching questions?
[17:43] <SpeedEvil> Probably.
[17:44] <hburger> Actually first, how do you calculate the descent rate of the balloon?
[17:44] <SpeedEvil> you use the drag formulae, and the parachute drag and the weight
[17:44] <hburger> I'd basically like to make sure the values I've entered into the CUSF are correct
[17:46] <hburger> GFS definition? What do I enter for that?
[17:46] <SpeedEvil> where are you entering these?
[17:47] <hburger> http://habhub.org/predict/
[17:48] <SpeedEvil> you don't need to enter that
[17:48] <SpeedEvil> scroll to where you want to launch.
[17:48] <SpeedEvil> (you will need permission)
[17:48] <hburger> Yup
[17:48] <SpeedEvil> click 'set with map'
[17:49] <hburger> mhm
[17:49] <hburger> (I have permission)
[17:49] <SpeedEvil> Set a time, an ascent and descent rate, a burst alt, and that's it
[17:49] <SpeedEvil> from the CAA?
[17:51] <hburger> Yep
[17:51] <hburger> So, nothing with GFS or Lat/Lon?
[17:53] <SpeedEvil> If you want to enter the lat/lon, you can.
[17:53] <SpeedEvil> Or you can just set it with the map
[17:53] <hburger> (the deltas, I mean)

[19:55] <Lunar_Lander> hi nosebleedKT
[19:55] <nosebleedKT> hi all

[19:56] <nosebleedKT> I was in a hackerspace meeting tonight
[19:56] <costyn> Laurenceb_: http://ubuntuforums.org/showthread.php?t=1497384
[19:56] <nosebleedKT> but electronics were so low experience

[19:57] <nosebleedKT> arduino blinking leds and stuff :(
[19:57] <costyn> Laurenceb_: might be a ACPI problem
[19:58] <costyn> Laurenceb_: where the paste-bin ends your laptop rebooted?
[19:58] <Laurenceb_> no it didnt reboot
[19:58] <Laurenceb_> only logged me out it looks like
[19:58] <Laurenceb_> but killed all my processes
[19:59] <costyn> Laurenceb_: ok, so what was described in my link wasn't what you had
[19:59] <Lunar_Lander> oh nosebleedKT
[19:59] <Laurenceb_> no
[20:00] <costyn> Laurenceb_: try an ls -ltra in /var/log, the last changed logs should be at the bottom. see if you can find anything else which changed around the time you were logged out
[20:01] <costyn> Laurenceb_: daemon.log might have something
[20:02] <costyn> although I'm mostly familiar with servers running ubuntu (and linux in general); there might be userland processes running which could have caused this
[20:02] <Laurenceb_> where is daemon.log?
[20:03] <costyn> Laurenceb_: should also live in /var/log

[20:12] <Laurenceb_> about 4
[20:12] <Upu> move group / copy group 2 simple things that Eagle makes epically hard
[20:13] <GW8RAK> Okay, thanks Upu. Just wondering about the smoothness of the North Sea. Two good videos.
[20:13] <costyn> Laurenceb_: same day or once a day?
[20:13] <Laurenceb_> same day
[20:13] <Upu> yeah it was very very smooth
[20:13] <Upu> pictures later on it was almost bottle glass smooth
[20:13] <costyn> Laurenceb_: was the laptop busy at the time? high load?
[20:13] <Laurenceb_> yeah
[20:14] <Laurenceb_> heavy load when it went down
[20:14] <costyn> Laurenceb_: might be overheating, you could install the package 'sensors' to see your cpu temp and such
[20:14] <Laurenceb_> hmm yeah ok
[20:15] <costyn> Laurenceb_: try searching for 'computertemp' in synaptic
[20:15] <costyn> Laurenceb_: there are several programs available for temp monitoring, check this thread (one of many) http://ubuntuforums.org/showthread.php?t=1494180
[20:15] <costyn> I'm gonna go give the missus some attention... ttyl!
[20:16] <Laurenceb_> ive used sensors before
[20:16] <Laurenceb_> thanks for the help

[20:20] <daveake_> Well, that was fun .... I've written a little DF-ing program for my car PC. It shows a big arrow pointing to where the payload is, based on the direction from car to payload and the direction the car is going in.
[20:20] <daveake_> So I've tested it by driving round the nearby roads. :)
[20:20] <Lunar_Lander> cool
[20:21] <daveake_> It also shows which way the payload is going, so you get an idea of where to go.
[20:22] <Lunar_Lander> yay!

[20:28] <daveake_> It did feel quite neat a I drove around :-)

[20:29] <Lunar_Lander> that sounds good
[20:29] Hiena (~boreger@ left irc: Remote host closed the connection
[20:29] <daveake_> The main arrow's length depends on distance to payload. On the end of that there's a second arrow showing the direction the payload is going, and the length of that arrow shows how far it will have moved before it lands, or the car arrives, whichever comes first.
[20:29] <Lunar_Lander> yeah
[20:29] <daveake_> Can't be very accurate with that last bit, but at least it gives an indication of where to go
[20:31] <Lunar_Lander> yea
[20:35] <Lunar_Lander> was it difficult to program?
[20:35] <Laurenceb_> http://www.youtube.com/watch?v=011WFfB0GSo&feature=related
[20:35] <Laurenceb_> ok so they owned by air drum idea
[20:37] <daveake_> Lunar_Lander - no ... I found some code on the web for calculating direction and distance between a pair of longitude/latitude points. Other than that it's decoding of the RTTY text to get the HAB position etc., and decoding of the NMEA strings from the car's GPS receiver. Finally a bit of graphics.
[20:38] <Lunar_Lander> yea

[21:38] <griffonbot> Received email: Anthony Stirk "Re: [UKHAS] uBlox NEO-6Q"
[21:41] <nickolai> i'm wondering about the lassen iq, if anyone has any input.... in the manual (gpsd.berlios.de/vendor-docs/trimble/trimble-lassen-iq.pdf page 28-29) it says rx ports must be connected to vcc via a pullup, but in this schematic (http://www.pegasushabproject.org.uk/wiki/doku.php/missions:ballasthalo:lassenbreakout#schematic) they seems to imply you don't need to connect the one you're not using...

[21:46] <NigeyS> nickolai, just on the rx / tx you are using is required
[21:47] <fsphil> you only need to pull-up the gps's rx lines that you are not using
[21:48] <fsphil> it's to stop it floating and potentially generating random commands
[21:48] <nickolai> ok, so if i leave the one i'm not using floating it wont matter since i'm not reading from it?
[21:50] <fsphil> the gps is reading from it though :)
[21:51] <nickolai> ok, that makes more sense
[21:52] <nickolai> though the schematic to which i linked (and NigeyS) seem to imply the opposite for some reason...
[21:52] <nickolai> given that the failure mode for leaving pin 3 floating, according to the manual, is it will never produce a position fix, i think i'm confirming that... :-/
[21:54] <fsphil> not sure, I thought it was just to stop random commands being triggered in the gps
[21:55] <nickolai> yea, from reading the first couple google results on pullup resistors that makes sense
[21:55] <zyp> floating inputs amplify noise
[21:56] <nickolai> i'm trying to figure out how to get the thing to output gpgsa sentences so i can see what sort of satellite info its getting
[21:57] <fsphil> you might just be able to connect the gps rx pin to gnd
[21:57] <fsphil> the one that's not used
[21:57] <fsphil> (not expert advice ;-)
[21:58] <nickolai> haha thanks
[21:58] <nickolai> still trying to figure out how to command this thing using the rtcm protocol
[21:58] RocketBoy (steverand@5acfd4f7.bb.sky.com) left #highaltitude.
[21:59] <nickolai> i don't have an antenna for it so it's very possible that it can't produce a fix cuz it doesn't have a good signal
[21:59] <zyp> or vcc, since uart lines are high when inactive
[21:59] <fsphil> gnd is safer :)
[22:00] <zyp> how so?
[22:00] <fsphil> it's an rx line
[22:01] <zyp> so as long as you're within gnd-vcc you're fine
[22:01] <zyp> vcc should never be higher than vcc ;)
