[00:03] <eroomde> gloria in excelsior
[00:03] <eroomde> the hesitence to avoid putting things on the bottom side is notvalid for solder jumpers
[00:04] <Randomskk> yes, solder jumpers very happily sit on the bottom
[00:04] <eroomde> shifting them to the bottom buys me acres
[00:07] <eroomde> this adc has all sorts of wiredness config pins
[00:07] <eroomde> an internal digital FIR filter that seems to have been designed by someone who never quite got nyquist
[00:07] <Randomskk> :(
[00:07] juxta (~rootkit@ppp203-122-193-94.static.internode.on.net) joined #highaltitude.
[00:08] <eroomde> the cutoff frequency is half the sample rate, constrained, it seems to be
[00:08] <eroomde> which is fine in theory but not really in practice
[00:08] <eroomde> you want it like <=1/5 the sample rate
[00:08] <Randomskk> does depend a bit on your reconstruction filter n stuff
[00:08] <Randomskk> 1/5 seems overly conservative
[00:09] <Randomskk> this is just to stop aliasing?
[00:09] <eroomde> this is going on the shape of the FIR they give
[00:09] <eroomde> it's not that good
[00:09] <eroomde> yes, for antialiasing
[00:09] <eroomde> it was only like 20dB down at the sample rate freqeuncy
[00:09] <Randomskk> oh lol
[00:10] <eroomde> which is not stellar
[00:10] <Randomskk> yea that's pretty poor
[00:10] <eroomde> so we've put a nice 4 pole bessel in analog which has flat group delay
[00:11] <Randomskk> adc has other appealing features?
[00:11] <Randomskk> (active bessel with those opamps?)
[00:12] <eroomde> natch
[00:12] <eroomde> yeah it's nice in other respects
[00:13] <eroomde> the simultaneous sampling is nice, as customers always ask
[00:13] <Randomskk> I can imagine
[00:13] <eroomde> even though the sigproc person in me says it doesn't matter
[00:13] <Randomskk> you know what they say about customers :P
[00:13] <eroomde> and the noise performance is very good
[00:14] <eroomde> the interface is a bit cooky
[00:14] <eroomde> i think designed for DSPs that have quite configurable interfaces
[00:14] <eroomde> but you can basically just do SPI with it
[00:14] <eroomde> there's an 8 bit parallel interface too
[00:15] <eroomde> there's a random pin that pulses every time you read out 8 channels and wrap back
[00:15] <eroomde> so you can see it's designed with fpga's in mind
[00:15] <eroomde> but yeah, it's quite nice
[00:15] <eroomde> differential inputs
[00:15] <eroomde> hmm
[00:16] <eroomde> that's about it really
[00:16] <Randomskk> yea does sound like an fpga thing. still, fe
[00:16] <eroomde> decent onboard ref tho i'm using an external as we're shotting for 0.1% accurate b4 calibration
[00:16] <eroomde> i.e., don't need to bother with calibration for most instrumentation purposes
[00:16] <Randomskk> yup
[00:16] <Randomskk> how good is the internal one?
[00:18] <eroomde> not far off but not quite as good
[00:18] <eroomde> can't remember, tis in my logbook somewhere
[00:18] <eroomde> noise was a bit more
[00:19] <eroomde> accuracy was slightly looser
[00:19] <Randomskk> easy enough to stick an external reference on there I guess
[00:19] <Randomskk> right, bedtime
[00:19] <Randomskk> good luck with the rest of those airwires
[00:19] <eroomde> so it is
[00:19] <eroomde> ta
[00:19] <eroomde> i might give up tbh
[00:20] <eroomde> unsurprisingly
[00:20] <Randomskk> are you still at work?
[00:20] <eroomde> gotta put in a whole long day tomorrow
[00:20] <eroomde> yes
[00:20] <Randomskk> :|
[00:20] <Randomskk> yea it's a bit late and all
[00:20] <eroomde> it's because i love it so
[00:20] <Randomskk> I can totally see that happening to me
[00:20] <Randomskk> wombat kept me up til 6am or so
[00:21] <Randomskk> but when I started there was no pcb and when I finished it was all routed and parts sourced and ordered and PCB ordered and stencil ordered
[00:21] <eroomde> sadly i have another board to do tomorrow
[00:21] <eroomde> 2 infact
[00:21] <Randomskk> ouch
[00:21] <eroomde> happily they're both much simpler
[00:21] <eroomde> this is the one that counts
[00:21] <Randomskk> that's some consolation
[00:21] <eroomde> it has an exciting future :)
[00:21] <Randomskk> how fast is the SPI bus running to get that much data through?
[00:22] <Randomskk> 32ch and 16bps and 200ks/s is a lot
[00:22] <eroomde> not really
[00:22] <eroomde> oh sorry misread
[00:22] <eroomde> yes it is at 200
[00:22] <eroomde> but that's totally not necessary for getting the data i need
[00:22] <eroomde> 10kHz is more than enough
[00:22] <eroomde> and that's like 1MBit
[00:22] <Randomskk> ah okay, that's pretty fine then
[00:22] <Randomskk> yea
[00:22] <eroomde> which is squeezy peasy
[00:23] <Randomskk> well, have fun :P
[00:23] <Randomskk> not that I need to tell you
[00:23] <Randomskk> zzz

[09:25] <HixWork> oh, with the 34000 prediction, I may even pick that up in the office

[09:25] <number10> where is office HixWork ?
[09:27] <HixWork> Thames Effluent, just outside Basildon [Bas Vegas]
[09:27] <number10> nice
[09:28] <HixWork> mmm yeah :)
[09:28] <HixWork> Still i should have my crimp tool and pins today, shiny shiny tidy cabling
[09:30] <gonzo_> when you have a certain bulk of cable. It's impossible for it to be tidy, nomatter how shiney it is!
[09:31] <gonzo_> the undersade of my desk shocks even the most cluttered hams
[09:31] <fsphil> hide it under something
[09:32] <gonzo_> I do, the desk!
[09:33] <HixWork> deska and floors are not subject to tidy rules in my book. I was referring to my payload and general electronics tests.
[09:33] <gonzo_> have to post a photo. Even I am astounded by it all
[09:34] <HixWork> Ribbon cable and 0.1" terminals should keep things relatively neat whilst trying things out
[09:34] <mfa298> tidy cabling is usually s sign of some other problem
[09:35] <gonzo_> ah, yep. My actual kit is neatly built. It's the interconnectes that are taking over the world
[09:35] <number10> I would be careful of connectors on payload - especially if they are not locking
[09:36] <HixWork> just for testing, for flight, things will be glued/nailed/rivetted/atomically bonded etc etc
[09:36] <number10> on my first flight I knocked the gps connector just before launch - fortunately someone who was looking at spacenear mentioned that the position was not varying
[09:36] <HixWork> got smd led to indicate lock on pcb
[09:37] <number10> thats useful
[09:37] <HixWork> I'm not aiming for floats so batt life not critical
[09:40] <HixWork> aren't you out eastr Number10?
[09:40] <HixWork> east even

[09:59] <jlgaddis> hey guys, question that i'm sure will be difficult to answer... if a few of us (friends and i) decided we wanted to do one of these balloon launches, what would be a rough ballpark figure of the costs involved (assume we have nothing starting out). $200-$300? $1000?
[10:00] <NigelMoby> well in the u.k around £250 for the first launch
[10:00] <NigelMoby> as we have to buy ssb capable receivers
[10:00] <NigelMoby> but ure in the u.s?
[10:01] <jlgaddis> yes
[10:02] <jlgaddis> i've been reading a *lot* lately about several launches that have been done and have a good idea of what all is needed, i just haven't began to start pricing anything out.
[10:02] <NigelMoby> you get to use Aprs which is generally cheaper as is the helium
[10:02] <jlgaddis> i assume, too, that some of the stuff can be used over and over again, so that'd reduce the costs of subsequent launches
[10:03] <jlgaddis> like, i see guys reusing cameras, gps receivers, etc.
[10:03] <NigelMoby> yup, probably safe to say $200 or there abouts.
[10:04] <HixWork> SDR shaves a big chunk out of the cost receiver wise
[10:04] <NigelMoby> true hix
[10:05] <HixWork> wish i'd known that before purchasing a badly hacked AR8000 :/
[10:05] <jlgaddis> i've read several articles that say to avoid hydrogen and use helium (at least at first), but not *why*. i'm sure there's a good reason, but i can't really figure out what it is.
[10:05] <Cie> Here we go, payload is on the map.
[10:05] <NigelMoby> h2 is volatile and explosive
[10:05] <daveake> Does anyone dare remove Oernen-II from the map? :)_
[10:06] <NigelMoby> helium is inert
[10:06] <jlgaddis> ahhh, that makes sense, thanks.
[10:06] <NigelMoby> lol do it dave

[10:08] <HixWork> heh
[10:08] <NigelMoby> hixwork what was badly done?
[10:08] <NigelMoby> to the ar8000...
[10:09] <HixWork> it had been pulled apart and sockets added and badly put back togehter, the 0.1" pins that connect the two boards had been bent
[10:09] <NigelMoby> oh eck
[10:09] <HixWork> it was just messily done.
[10:09] <HixWork> but I knew far less back then
[10:09] <HixWork> grrrr
[10:09] <NigelMoby> heh
[10:10] <HixWork> but I have 2 dongles now so it's all good

[11:02] <LazyLeopard> .077 is wiped out by noise from something here this morning.
[11:02] <LazyLeopard> VORTEX4 at 434.325.4 is a bit wobbly here, but not swamped by noise.
[11:03] <M0JCU> All payloads up
[11:03] <M0JCU> (but you worked that out anyway)

[11:06] <LazyLeopard> Not hearing VORTEX3 and VORTEX might be there but is drowned by noise. VORTEX4 still wobbly
[11:07] <costyn> NigelMoby: ok, no worries. thx
[11:07] <M0JCU> Helioss is solid here.
[11:08] <M0JCU> The signal from Vortex 3 disappeared as we launched. I hope we didn't catch the switch :)
[11:09] <navrac_work> can hear vortex4 - but nothing else atm
[11:09] <gonzo_> you can check on recovery
[11:09] <gonzo_> good helios sigs
[11:10] <M0JCU> navrac_work, Vortex 4 is good :)
[11:10] <vortex_chase> should have a stronger VORTEX signal now
[11:10] <daveake> Helios and Vortex4 both great here; others not a sign
[11:12] <M0JCU> Vortex is on 434.077 but very faint
[11:12] <gonzo_> not getting solid decode on helips though, even with decent sigs
[11:13] <daveake> Actually vortex4 is fading in and out so not getting many decodes
[11:13] <Heloiss_chase> We're still getting partials off Helioss
[11:13] <M0JCU> have you checled the filter bandwidth?
[11:13] <daveake> Helios best for me
[11:13] <gonzo_> yep, was at 400hz, just wound iit out a bit more
[11:15] <M0JCU> daveake, please could you stick with Vortex4?
[11:15] <M0JCU> HelioSS is well covered
[11:17] <daveake> I have 2 recivers on Vortex4!
[11:17] <navrac_work> helios is strongest here - vortex4 fades a bit - no sign of vortex or vortex3 here
[11:17] <M0JCU> Thanks!
[11:17] <daveake> and on different aerials
[11:18] <M0JCU> I think Vortex must have a broken antenna. We'll find out about Vortex 3 later
[11:18] <gonzo_> all on the one balloon?
[11:19] <M0JCU> vortex_chase, Heloiss_chase prections at time of launch are still good.
[11:19] <M0JCU> Ascent rate is spot on prediction

[11:32] <sjohn> hello, what should the max weight be for the payload?
[11:32] <LazyLeopard> Argh! Where's the setting that lets fldigi folly RTTY in fequency gone...
[11:33] <navrac_work> vortex4 is very fadey - good partials but deep fades so missing odd bits
[11:33] <fsphil> LazyLeopard: "Dl Client"
[11:33] <LazyLeopard> No, it was the AFC button got unclicked somehow...
[11:33] <fsphil> ah
[11:33] <M0JCU> vortex4 should improve significantly after separation. The antenna is packed with the parachute at the moment
[11:34] <M0JCU> Vortex has no excuse for poor signal

[11:36] <M0JCU> vortex_chase, no luck with Vortex. I think the antenna is bust
[11:36] <M0JCU> Vortex 4 is OK. I suggest you switch

[11:50] <fsphil> heavy antenna? all you need is a strip of coax

[11:53] <daveake> sjohn No you don't need special permission
[11:54] <daveake> sjohn However, the antenna need only be a few grams what's special about this one?
[11:54] <HixWork> just a big chute :)
[11:54] <gonzo_> are isotropic the ones in the roof space withwater and special lights?
[11:54] <sjohn> the antenna is 600grams
[11:54] <costyn> wat
[11:54] <daveake> What type? Why so heavy?
[11:54] <x-f> a small, stearable dish?
[11:54] <costyn> lol

[11:55] <griffonbot> @adamcudworth: Vortex4 flight being tracked using HABHUB iOS app - light grey line is live prediction #ukhas http://t.co/GGKleWpAl5 [http://twitter.com/adamcudworth/status/309633369761779712]
[11:55] <HixWork> sjohn http://goo.gl/hyaBB
[11:56] <daveake> sjohn a few grams of coax/wire work just fine you don't need anything else and I *seriously* advise against adding something that heavy without a very good reason
[11:56] <gonzo_> but make it from flexi wire, for weight saving and mor important, saftey
[11:57] <gonzo_> (and that design was for 144MHz, a 434MHz one will be smaller
[11:58] <daveake> From ze wiki: "We strive to construct as light a payload as possible - this both makes it safer in flight and on landing but also allows us to optimise our flights as we require less helium and can achieve even higher altitudes."
[11:59] <M0JCU> vortex_chase, change of destination
[11:59] <vortex_chase> JCU-does Vortex_chase need to update googlemaps?
[12:00] <M0JCU> yes
[12:00] <Elwell> didn't someone fly a slim jim recently?
[12:00] <costyn> balloons are also applicable to Lotus' Chapman's oft-stated philosophy of automotive design: "Simplify, then add lightness."
[12:00] <Heloiss_chase> In traffic
[12:00] <M0JCU> on M25? There's a surprise
[12:01] <M0JCU> 3 minutes to cut-down
[12:02] <Darkside> hrm
[12:02] <sjohn> its for antenna testing reasons, but altogether i am expecting 1.5kg, i was asking if it was legal?
[12:05] <sjohn> if it goes over i am certainly going to use the dipole strip of wire
[12:05] <M0JCU> going down
[12:05] <M0JCU> Cutdown worked
[12:05] <vortex_chase> good news
[12:06] <PE2G> At dx 512 km VORTEX4 difficult due to fading, HELIOSS undecodable due to local QRM
[12:06] <daveake> sjohn First test I would make is "is it too heavy for HAB?" Answer: Yes. End of testing.
[12:06] <mfa298> sjohn: I can't comment on legality but you might want to consider what happens to anything it comes down on especially if it's a bit fater than expected and lands on a person (think worst case scenarios)
[12:07] <S_Mark> vortex4 fast decent!
[12:07] <daveake> Vortex4 much better after cutdown :)
[12:07] <Elwell> yeah. Always put someone elses phone no on the patload (j/k)
[12:07] <daveake> S_Mark That speed is normal at that altitude
[12:07] <M0JCU> vortex_chase, sorry - back to original destination
[12:08] <vortex_chase> is that Wellingborough?
[12:08] <LazyLeopard> Wowo! Two green lines in succession! ;)
[12:08] <Heloiss_chase> good signal on helioss
[12:08] <Heloiss_chase> still same route?
[12:09] <S_Mark> daveake when does the thicker air take hold of the chute usually?
[12:09] <Jess--> might not be too popular dropping vortex 4 on cranfield, it's pretty busy as a training airfield
[12:09] <S_Mark> 20k?

[12:09] <vortex_chase> ok, thanks JCU

[12:10] <navrac_work> Elwell - yes I've flown slim jims and jpoles before
[12:10] <gonzo_> M0JCU, is the cutdown commanded or gps controled?
[12:10] Action: LazyLeopard was just thinking that the descent was surprisingly gentle... ;)
[12:10] <PE7ER> yeay first decode at frame 1461 on helios!
[12:12] <M0JCU> gonzo_, GPS controlled. 25km + 30 seconds
[12:13] <M0JCU> Heloiss_chase, Current destination is perfect
[12:13] <daveake> S_Mark There's some maths, but basically if you take the rate at 20km and divide by 4, that's your landing speed. Normal landing speed 5m/s so you should see somewhere around 20m/s at 20km

[13:51] <number10> I use it in the car chasing
[13:51] <number10> also if I am recieving the balloon I can do a tracklog
[13:52] <NigeyS> grr ignore microchu forgot microchu started in online mode, can someone wipe it off the tracker pls ?
[13:53] <daveake> done
[13:53] <HixWork> oh, cool, so you can integrate dl-fldigi with memory-map then?

[13:56] <number10> no I take the data from fldigi and create a tracklog file which I can read into memory map HixWork
[13:57] <HixWork> ah ok, got a bit overexcited there :)

[13:57] <number10> it would be good if you could
[13:59] <HixWork> thinking it'd be nice if you could outpur the data fromdl-fldigi to a virtual com port and have that acting as a virtual gps in MM...
[14:00] <gonzo_> interesting that they both did a little jump to the east before landing. Some odd wind shere ?
[14:01] <gonzo_> shear
[14:01] <M0JCU> vortex was going to the west of prediction all the way down
[14:01] <M0JCU> helioss less so but stil there
[14:01] <number10> I was thinking of doing that HixWork but I thought it was more useful to have your car position on the map and then enter the balloon position as a mark

[14:08] <number10> yes, here is a snap of the tracklog for helioss http://i.imgur.com/RmURt1p.jpg
[14:08] <number10> yes daveake has a screen with a pointer to the direction of the balloon

[14:11] <HixWork> so i can have dl-fldigi, SDR# and MM running for chase
[14:11] <number10> have you done a chase yet HixWork ?
[14:11] <HixWork> nope, I'm a HAB virgin
[14:12] <HixWork> the new Lunar if you will [well without the 5 years bit]
[14:12] <daveake> end of an era
[14:12] <HixWork> heh
[14:12] <number10> when you get setup, its a good idea to ask someone if you could chase their ballon if it happens to be landing not far from where you live
[14:13] <HixWork> if only there was an opensource routing system for openstreetmap
[14:13] <HixWork> that'd be great to integrate landing posn with
[14:13] <daveake> Good idea. WHen I did my first launch, I was reasonably well prepared for the launch itself, but not at all for the chase
[14:13] <number10> there is a way to do it withgoogle earth
[14:13] <HixWork> I've thought of it number10, but everything of late has been a distance away
[14:14] <HixWork> google earth relys on 3G though. I was trhinking purely offline
[14:14] <HixWork> as we all know, tech fails when you need it most
[14:14] <HixWork> hence I have a Silva compass on my climbing rucksac - old skool just works come hell or high water :)
[14:15] <number10> ah well _ somehow though google eeath you could locally stor some maps
[14:15] <Geoff-G8DHE_> You can cache a fair number of detailed maps in GE so it continues offline
[14:15] <number10> thought
[14:15] <HixWork> hmm.
[14:15] <HixWork> but the routing part would still need connection to the server i'd have thought
[14:15] <Geoff-G8DHE_> Just turn up the cache size, and then follow the route and the required levels.
[14:16] <Geoff-G8DHE_> I use it for planning phto shoots sunsets down valleys etc.
[14:16] <number10> as long as you are receiving the payload telemetry on fldigi you can extract the location and update a kml file

[18:01] <Randomskk> yea
[18:01] <arko> nice work!
[18:01] <Randomskk> not that I see any other 5x2s :P
[18:01] <eroomde> the otherstuff a daughter, sensor specific card will need
[18:01] <arko> too bad you cant rest yet
[18:01] <eroomde> so the main connectors are just differential inputs
[18:01] <eroomde> ch0+, AGND, ch0-, AGND, ch1+... etc
[18:01] <arko> or maybe you can, but i tend to lose sleep worrying i forgot to run something
[18:02] <arko> schematic end really
[18:02] <eroomde> the 5 x 2 header has a low impedenace precision 10V ref, useful for exciting bridges or generating a constant current supply or whatever, based off the same ref the adc uses so it's always ratiomatric
[18:02] <eroomde> there's a +15V, -15V, and GND supply
[18:02] <eroomde> and then there's I2c for configuring random things
[18:02] <eroomde> eg an i2c temp sensor on the pressure sensor board for temp calibration
[18:03] lz1dev (~lz1dev@46.47.80.192) joined #highaltitude.
[18:03] <Randomskk> cool, makes sense
[18:03] <eroomde> but could just as well be used for config, or one wire ident chips that we sometimes put in individual sensors so we know automatically what sensor is plugged into each channel, and then the pc can lookup calibrationd ata for that sensor automatically
[18:03] <eroomde> and label the legends on the graphs appropriately
[18:03] <eroomde> and so on
[18:04] <Randomskk> nice
[18:04] <eroomde> it just passes through the adc card from the back plane
[18:04] <eroomde> completely isolated
[18:04] <eroomde> and the adc part of this card is also galvanically isolated from the backpane
[18:04] <Randomskk> kinda weedy via to ground between those two capacitors on the +-15V going to the 5x2?
[18:04] <arko> what adc card are you using?
[18:04] <eroomde> so it can float with the host object
[18:04] <eroomde> arko: this is the adc card
[18:05] <eroomde> i just designed it
[18:05] <eroomde> Randomskk: top copper pour in that region still to be done
[18:05] <arko> wait what
[18:05] <arko> im confused now
[18:05] <eroomde> this card takes bridge-type sensors in on the left
[18:05] <arko> that chip it all leads to is an mpu or adc?
[18:05] <eroomde> and converts it to digital and interfaces to the backpane on the right
[18:05] <arko> does diff
[18:05] <eroomde> i can stack 4 of these cards vertically
[18:06] <arko> oh derp
[18:06] <arko> i get it
[18:06] <eroomde> and then put a little board with a microcontroller and ethernet bridge on the top to send all the samples back over ethernet
[18:06] <eroomde> yep that chip is just an adc
[18:07] <eroomde> Randomskk: it would work fine from a current point of view because the aux connector ground is connected back to the dc dc coverter brick on the bottom copper side, you can see
[18:07] <arko> ok cool
[18:07] <eroomde> but for emc reasons i want the loop to come back to by the output capacitors
[18:07] Maxell (~Maxell@ipv7.xs4all.nl) left irc: Ping timeout: 264 seconds
[18:07] <arko> how much data is that per second anyway?
[18:07] <eroomde> recall the top copper tracks are +15V and -15V, and GND is the bottom copper pour
[18:08] Maxell (~Maxell@ipv7.xs4all.nl) joined #highaltitude.
[18:08] <eroomde> from each card, 8 (channels) * 16(bits) * sampling freq, which probably wont ever need to go about 10kHz
[18:08] <eroomde> so that would be just over 1MBit
[18:08] <cuddykid> hey Upu
[18:08] <Upu> hi there
[18:09] <Cie> +c
[18:09] <Cie> heh or rather /c
[18:09] <cuddykid> Upu: any luck figuring out what I destroyed?!
[18:09] <Randomskk> also on the +15/-15V taps going to those test points (?) why do you even via the bottom one?
[18:09] <Upu> not yet I've renmoved the rfm but not had chance to go further yet
[18:09] <cuddykid> Upu: no worries - there's no rush :)
[18:09] <Randomskk> breaking up that ground plane :(
[18:10] <eroomde> i have no idea!
[18:10] <eroomde> total brain fart
[18:10] <eroomde> i suspect it made sense once then i moved something
[18:10] <Randomskk> might be worth moving the via on the top one closer to the trace so it runs less on the bottom
[18:10] <eroomde> however, as i say i've still to sort out the exact current path for that section
[18:10] <Randomskk> I really like the bit of ground plane under the i2c/whatever traces from the 5x2
[18:11] <Randomskk> it looks so neat :P
[18:11] <eroomde> as with high speed switching things it's all about the path to the final output cap
[18:11] <Randomskk> mm
[18:11] <eroomde> yes it's convenient that i can run that under the dc/dc
[18:11] <Randomskk> so long as that cap is well grounded, though, otherwise it doesn't really count as the final output cap :P
[18:12] <eroomde> it will be when i get round to the top pour and vias
[18:12] <Randomskk> mm I'm sure
[18:12] <Randomskk> is the SPI from the ADC going through isolators before the main connector there?
[18:12] <eroomde> yep
[18:12] <Randomskk> that's nice
[18:13] <eroomde> got about 15kV isolation between the backpane and the rest of the circuit
[18:13] <Randomskk> pretty happy pcb
[18:13] <eroomde> it's nearly there
[18:13] <eroomde> i don;t have to get the gerbers out tonight anymore
[18:13] <eroomde> which is good
[18:13] <eroomde> can wait till tomorrow as customer has delayed by 4 days
[18:13] <arko> bah
[18:13] <eroomde> buys me some time to sleep on it
[18:13] <arko> great timing to find that out
[18:14] <eroomde> yup!
[18:14] <arko> does it really push much data?
[18:14] <eroomde> i needn't be another late night at work

[18:16] <arko> very nice
[18:17] <eroomde> but i am working on an interface card based on an fpga that will use spacewire
[18:17] <eroomde> ssssshhhhhhh
[18:17] <arko> ha!!
[18:17] <arko> i was just thinking..
[18:17] <arko> feels like an fpga problem
[18:17] <arko> well, a problem that could use one
[18:19] <eroomde> sure, separating the adc cards from the interfacey bits makes it futureproof

[19:01] <Elwell> girl, fashion shopping
[19:01] <dg9bfc> aehem ... just came online ... any news about vortex4?
[19:01] <Upu> recovered
[19:01] <eroomde> ah, well an technical IRC channel is definitely the right place to ask about that
[19:01] <Elwell> so new soldering iron or welder won't go down well
[19:01] <arko> Elwell: cant help there
[19:01] <arko> eroomde lol
[19:02] <dg9bfc> cool ... who found it?
[19:02] <Upu> dg9bfc Vortex4 was recovered I believe
[19:02] <Upu> not sure been afk all day
[19:02] <eroomde> by one of the vorticity staff
[19:02] <dg9bfc> is it ... or you believe that
[19:02] <Upu> no they got it
[19:03] <Upu> right need to afk to cook
[19:04] <dg9bfc> i helped with oernen :-) ... chattet with the team after touchdown (GOTCHA!) ... could copy sd card with all picture :-) yepp that was a nice hunt
[19:04] <eroomde> you met kevin?
[19:04] <eroomde> the man the myth the legend?
[19:04] <dg9bfc> yessssssssss
[19:04] <eroomde> wow

[19:06] <dg9bfc> yepp .. i live cöose to both points (launch and touchdown ... during flight could send data but me and my friend andi thought "hey lets catch it" and so decoding stopped after a while from here
[19:06] <dg9bfc> but we decoded in car with laptop and dvbt stick
[19:06] <dg9bfc> decoded last position in navi ... and gotcha
[19:07] <dg9bfc> predicted point and real point was only 500m difference!!!!!!
[19:07] <dg9bfc> if i had known how precise that prediction was ... i would have been there earlier
[19:07] <dg9bfc> but anyway it was a real fun
[19:08] <dg9bfc> exchanged email adresses
[19:08] <eroomde> nice
[19:08] <dg9bfc> and i got a souvenier :-)
[19:08] <eroomde> the predictor isn't too bad!
[19:08] <dg9bfc> plus a few hunderd pictures
[19:09] <dg9bfc> it was VERY good cause they cut the line nstead of balloon burst
[19:09] <dg9bfc> i did not know that before
[19:09] <eroomde> it's been a huge help to habbing
[19:09] <eroomde> it used to be that you just let go and pray
[19:09] <eroomde> hope it didn;t land in a town
[19:10] <dg9bfc> they sure will do another one ... and i am prepared :-)))))
[19:10] <dg9bfc> waterlanding
[19:10] <eroomde> hehe
[19:10] <dg9bfc> but a captain of a ferry recovered it
[19:10] <eroomde> yes, my group used to launch from cambridge, and the winds generally took it north-east
[19:10] <dg9bfc> and no damage
[19:10] <eroomde> and there's not much between cambridge and water to the northeast
[19:11] <dg9bfc> normally we (a few friends and I) track weather ballons
[19:12] <eroomde> oh cool, so you're pretty experienced with their behaviour
[19:12] <dg9bfc> but a day before lauch i got a notam from one of my hunting friends about the lauch of oernen
[19:12] <dg9bfc> yes i am experienced with weatehr ballon ...
[19:12] <eroomde> random general question - has anyone ever come across DIP chip sockets that have 90 degree legs?
[19:12] <dg9bfc> and .... we have to have a more precise transmitter
[19:13] <eroomde> eg if you have a dip bar of LEDs that you want to mount on a board edge
[19:13] <eroomde> what was wrong with your transmitter?
[19:13] <dg9bfc> it shifted bad in frequency
[19:14] <dg9bfc> so i had to retune every few seconds even with afc on dlfldigi switched on
[19:14] <eroomde> ah yes
[19:14] <eroomde> usually if the transmitters on the balloon are not very well thermally inslated they can drift around
[19:14] <eroomde> by several kHz
[19:14] <dg9bfc> and ... i had to retune shift and bw of filter for any good decode
[19:15] <dg9bfc> yes ... and that is bad when it shifts so much
[19:15] <bertrik> dg9bfc: I can receive a weather balloon every weekday from the national weather service, except it's at a not-so-convenient time (around 00:30 at night)
[19:16] <dg9bfc> i thought i could drive to landing spot and the decoding here at home would work ... but it stopped
[19:16] <bertrik> and there's no open-source software to decode it (as far as I know)
[19:16] <dg9bfc> otherwise complete track would be online
[19:17] <dg9bfc> no ... but why not use sondemonitor??
[19:17] <dg9bfc> bertrik ... email me pls direct
[19:17] <dg9bfc> call at freenet dot de
[19:19] <dg9bfc> i can receive 4 different stations all at good distances and from different directions ... so if wind comes from here or from there .. nearly everyday i have a good chance :-)
[19:19] <dg9bfc> a station in all 4 directions of compass rose :-)
[19:23] <dg9bfc> sadly i did not know about vortex 4 :-(
[19:23] <dg9bfc> otherwise i had been there :-)
[19:23] <x-f> you should join UKHAS mailing list - people announce their flights there

[20:33] <Upu> i still have a breakout for it if you want one
[20:33] <Upu> neo6m or 6q ?
[20:34] <chrisstubbs> 6m
[20:34] <Upu> yeah the cheaper one
[20:34] <Upu> doesn't have a TXCO
[20:34] <Upu> still works fine though
[20:34] <chrisstubbs> TXCO?
[20:35] <Upu> Temperature-Compensated Crystal Oscillator
[20:35] <Upu> May just slow lock times down
[20:35] <chrisstubbs> ah fair play
[20:35] <chrisstubbs> Will it work ok with your SMD chip antenna?
[20:36] <Upu> yep
[20:36] <chrisstubbs> Perfect :) You should have an order coming up soon for a few bits for me and domlin if all goes according to plan
[20:37] <chrisstubbs> Would it still be ok to order a handful of SMD bits like crystals, caps and resistors with it too?
[20:37] <Upu> cool thx
[20:37] <Upu> yeah just tell me what you want and I'll work out how much
[20:39] <chrisstubbs> thank you. going to home etch an "el-cheapo tracker" for dom. if it all works ok i will probably get some boards made up from hackvana (at last) :)
[20:39] <Upu> the foot print for the NEO is my Github library for Eagle
[20:39] <chrisstubbs> oh thats what i was meaning to ask. Do you have any SMD 3v3 low dropout regs in stock?
[20:40] <Upu> yeah
[20:40] <chrisstubbs> Yeah i found that thanks, saved a lot of work drawing pads etc :)
[20:40] <Upu> SOT23 ones
[20:40] <Upu> I think I'll have to check
[20:41] <chrisstubbs> Great, could you find me a price and the part number so i can stick it into the design please :)
[20:41] <Upu> sure
[20:41] <Upu> LDO ?
[20:41] <chrisstubbs> yes please
[20:42] <chrisstubbs> out of interest, would the LDO be ok being powered by 2x energiser AAA or would it need 3 to get above the dropout point for long enough to last a flight?
[20:43] <Upu> depends on how low the low in the regulator is
[20:43] <Upu> some are 250mV drop
[20:43] <Upu> you need 3 really
[20:43] <Upu> as energizers go from about 1.7v to 0.9v
[20:44] <chrisstubbs> ok thanks will bear that in mind. I dont suppose those regulators are in your eagle lib are they?
[20:45] <Upu> 1 sec let me check the ones I use

[20:54] <chrisstubbs> good price + suitable features, but farnells £20 minimum order thing puts me off
[20:54] <Randomskk> tried Rapid?
[20:54] <Upu> chrisstubbs samples :)
[20:54] <Randomskk> www.rapidonline.co.uk probably have something suitable
[20:55] <chrisstubbs> upu good plan, i will have a look! Atmel seem to enjoy sending me samples ;)
[20:57] <Lunar_Lander> NigeyS, me too, glad that I finally made it

[21:32] <anerDev> guys, this is a good yagi for receive the signal from ntx2 ?? http://www.ebay.it/itm/250826224761?ssPageName=STRK:MEWAX:IT&_trksid=p3984.m1423.l2649

[21:39] <mfa298> anerDev: likely to be reasonable for direction finding but if you're using it from a base location it will need to be pointed in the payload direction to work.
[21:40] <anerDev> yes yes, this is the priciple of yagi antenna !
[21:40] <mfa298> I get worried when antennas like that have such a big bandwidth value but for the price it's likely to be reasonable.

[21:41] <mfa298> in what situation are you planning on using it ?

[22:06] <anerDev> but
[22:07] <anerDev> the best is ground plane or yagi in mobile situation ?
[22:07] <mfa298> anerDev: it really depends on what you want to do.
[22:07] <anerDev> for example ?
[22:07] <x-f> you can't really use yagi while in a car
[22:07] <mfa298> I would use something that's omni directional on the car (not a yagi)
[22:08] <anerDev> in a car the groundplane is best ?
[22:08] <mfa298> but when you're on the ground the directional antenna like a yagi can be useful to work out what direction the signal is in
[22:08] <SpeedEvil> x-f: drill a hole in the roof
[22:09] <mfa298> what you're calling a groundplan antenna is one form of omni directional antenna
[22:09] Nick change: daveake1 -> daveake
[22:09] <x-f> SpeedEvil, yeah, i've seen Darkside's pimped ride :)
[22:10] <anerDev> :/
[22:10] <anerDev> I have a problem
[22:10] <SpeedEvil> x-f: bus drivers get real pissy though.
[22:11] <mfa298> for a car you want something thats omni directional with a vertical polarisation.
[22:11] <anerDev> because where I am there are hills and mountain I mo
[22:11] <mfa298> some sort of magmount antenna is best
[22:11] <anerDev> i move for keep the signal from ntx2
[22:11] <anerDev> for now I'm using a groun plane antenna
[22:12] <anerDev> but my doubt was "the best is ground plane or yagi ?"
[22:12] <mfa298> at 433MHz the signals are mostly line of sight. To get a good fix on where it lands you need to be fairly close.
[22:12] <anerDev> yes yes
[22:12] <mfa298> a good yagi may help with a marginal signal
[22:13] <anerDev> but for receive the signal the best solution is the yagi ? not the ground plane, or no ?
[22:13] <chrisstubbs> I think i have finished the schematic for a basic tracker, if anyone would be willing to take a look and point out any errors they may see with fresh eyes that would be much appreciated :)
[22:13] <chrisstubbs> http://chris-stubbs.co.uk/hab/SMDSCH.jpg
[22:13] <mfa298> however a decent colinear will have similar gain to the yagi you linked to
[22:14] <anerDev> but colinear antenna I can't use in the car !
[22:14] <anerDev> I can build and mount on my house
[22:15] Dan-K2VOL (~Dan-K2VOL@69.64.6.70) joined #highaltitude.
[22:17] <mfa298> for mobile in a car I'd use something like http://www.eham.net/reviews/detail/3129
[22:17] <daveake> Yup
[22:17] Dan-K2VOL1 (~Dan-K2VOL@69.64.6.70) left irc: Ping timeout: 276 seconds
[22:18] <anerDev> I save this in my bookmarks
[22:18] <anerDev> so, my ground plane is this: http://www.aurelwireless.com/wp-content/uploads/shortform/650200313G_sf.pdf
[22:20] <mfa298> that might not be so easy to use on a car as you'd need to fix it somehow. It also give very little info about it (radiation patterns, gain)
[22:21] <mfa298> the one I linked to has a magnetic base so you can put it on almost any car easily
[22:21] <daveake> Yep. Definitely the way to go for a car
[22:22] <anerDev> mfa298 where can I buy your model ?
[22:22] <mfa298> Search google, most ham shops should have something similar
[22:23] <anerDev> ok I'm searching ?
[22:23] <mfa298> Look for a ham 70cms or 2/70 magmount antenna
[22:23] <daveake> Or, a little less gain and a little less directional, http://www.ebay.co.uk/itm/3db-Antenna-aerial-433Mhz-RP-SMA-F-with-Magnetic-base-Ham-radio-/290868517257?pt=UK_Computing_Boosters_Extenders_Antennas&hash=item43b91d5989

[22:25] <daveake> Yes, I have that model. Works well
[22:26] <anerDev> fantastic !
[22:26] <anerDev> but I0m confused
[22:26] <mfa298> anerDev: that looks like a good one

[22:26] <anerDev> where is the best situation for use yagi antenna ?
[22:27] <jonsowman> cheaper ^
[22:27] <daveake> And in stock for a change :)
[22:27] <mfa298> yagi is good if there's a weak signal (a good yagi will have a higher gain than an omni directional antenna)
[22:27] <Upu> http://www.radioworld.co.uk/catalog/tonna_220329_pro-xl_29_elements_antenna_430_to_440_mhz-p-7777.html?osCsid=ef25cfce3064a6b81791b3b5df1819c6
[22:27] <daveake> Yagi is dorectional so it's handy when direction-finding after the payload has landed
[22:27] <jonsowman> 29 elem
[22:28] <jonsowman> wow
[22:28] <Upu> nice and portable
[22:28] <mfa298> yagi is also good if you can't decode so you can workout where it is by direction finding
[22:28] <jonsowman> yes, a mere 5m long
[22:28] <anerDev> the summary is:
[22:28] <daveake> Even the Shogun wouldn't accomodate that thing :)
[22:28] <chrisstubbs> awesome idea: cherry picker chase car
[22:28] <anerDev> yagi antenna: for weak signal
[22:28] <chrisstubbs> antenna on the top ;)
[22:29] <Upu> someone posted something like that chrisstubbs
[22:29] <daveake> and rotator :)
[22:29] <anerDev> groundplane antenna: general purpose (car, house, ..)
[22:29] <chrisstubbs> oh what
[22:29] <chrisstubbs> lmao
[22:29] <anerDev> colinear: for house
[22:29] <anerDev> is correct ?
[22:29] <jonsowman> roughly so
[22:29] <Upu> http://www.ebay.co.uk/itm/Iveco-Van-With-Cherry-Picker-/251236028727?pt=UK_CarsParts_Vehicles_CommercialVehicleParts_SM&hash=item3a7ed59137
[22:29] <daveake> magmount for car; not the gp-radial one you linked to
[22:29] <mfa298> something omni dirctional for house and car (unless you want to spend big bucks)
[22:30] <jonsowman> Upu: you need flossie
[22:30] <Upu> link ?

[22:30] <Upu> the 'f' stands for flipping

[22:31] <jonsowman> not sure why Flossie
[22:31] <jonsowman> daveake: oh it's all retractable
[22:31] <mfa298> That yagi Upu linked to look good, Now I just need the few 100k for a house to put it on :p
[22:31] <Upu> well if you're going to play antenna dick wagging thats going to win :)

[22:32] <anerDev> this is colinar antenne ?
[22:32] <anerDev> antenna ?
[22:32] <jonsowman> I think that's a yagi at the top
[22:33] <jonsowman> might be a dipole
[22:33] <natrium42> hey guys
