[00:00] <W6YRA> well, more footprint than range
[00:00] <W6YRA> but we stopped listening over an hour ago
[00:00] <jcoxon> oh well - this ballooning stuff ain't easy - take it from me
[00:00] <W6YRA> oh i know
[00:00] <W6YRA> I haven't flown one since 2007, but i know
[00:01] <W6YRA> honestly these new tools are great for web plots, path burst and landing predicts
[00:01] <W6YRA> the RTTY is great too, I was using APRS
[00:01] <jcoxon> yes we've made lots of progress
[00:01] <jcoxon> it has its charms - we find it more involving
[00:01] <jcoxon> as you can probably see by the number of stations in europe

[02:45] <W6YRA> arko: any idea what happened? were you able to find it?
[02:45] <arko> unable to sadly
[02:46] <arko> we drove to victorville
[02:46] <arko> with yagi's
[02:46] <arko> i was starting to run out of battery so i had to get the car going
[02:46] <arko> by then i couldnt hear it anymore for some reason
[02:46] <arko> so blakange1 and I drove out there to see if we could hear it
[02:46] <arko> but we got nasa
[02:47] <arko> nada*
[02:47] <arko> heh nasa too
[02:49] <arko> im cleaning up the data
[02:49] <W6YRA> did you lose it the same time I did or were you able to capture more?
[02:49] <arko> and coverting the register values into proper units
[02:49] <arko> lost it before you
[02:51] <W6YRA> hrm, ok. the signal was strong, and them bam nothing
[02:51] <W6YRA> is that a pcb you made yourself?
[02:51] <arko> yes
[02:51] <arko> was it RTTYing the whole way?
[02:52] <arko> or did it ever become just a carrier?
[02:52] <W6YRA> it went carrier, though after we verified our station and spun the dial looking i can't guarantee we ended up on the same carrier
[02:53] <W6YRA> but when we playback the wave you can see a faint carrier when the rtty stopped
[02:53] <W6YRA> i think there was some voltage instability which caused some impulsive shifts
[02:54] <W6YRA> but that's minor in comparison
[02:54] <W6YRA> first flight?
[02:56] <W6YRA> i'm wondering if you have another one & are going to try again
[02:58] Ben_L_ (~Jill@75.111.213.192) left irc: Ping timeout: 272 seconds
[03:00] <blakange1> yeah ithink he has more boards already
[03:00] <blakange1> but there are some components that are unavailable now that will have to be sourced
[03:04] <W6YRA> ok, let me know if you need the wave file or anything. I'll have to trim and encode it first
[03:06] <blakange1> yea arko might like that but i think he can get all the decoded packets that were sent to the tracker
[03:06] <blakange1> he said all the data he's gotten looks great already
[03:07] <arko> W6YRA: 4th flight new radio board
[03:07] <arko> W6YRA: i plan to launch more of these in the coming months
[03:07] <W6YRA> ok, so 1st flight of this board
[03:07] <arko> smaller balloons/payloads
[03:07] <arko> correct
[03:07] <arko> it also had a pesky sensor
[03:08] <arko> needed it for my lab
[03:08] <arko> at cal poly pomona

[03:20] <arko> interesting how the gps glitched up
[03:27] <arko> W6YRA: im fairly certain the burst damaged the payload or something
[03:28] <arko> seems it gave a last blip right after burst
[03:28] <arko> perhaps ground antennas got damaged
[03:28] <arko> gonna use piano wire like Upu said next time
[03:28] <W6YRA> early burst, 8km below predict.
[03:28] <arko> ah
[03:29] <arko> that was an incorrect estimate
[03:29] <arko> 24601m was the actual estimated
[03:29] <arko> we were about ~400m off
[03:29] <arko> so a good fill thankfully
[03:29] <W6YRA> is that little ceramic antenna the uhf rtty?
[03:30] <arko> that's the gps antenna
[03:30] <arko> http://www.flickr.com/photos/arkorobotics/10957480156/
[03:30] <arko> this is what actually flew today
[03:30] <arko> its a bit fatter because it required a sensor
[03:30] <arko> the white pcb you see is the smaller version of this without the sensor
[03:31] <arko> the thing is, if the radio was still working, it would have been in line of sight to both of us
[03:33] <W6YRA> yeah, either it failed or something upstream did
[03:37] <arko> if you drink beer, i'll likely be in the ucla area sometime soon, I owe you one :)
[03:38] <W6YRA> sure do! stop by and I can show you the shack
[03:38] <arko> hell yea
[03:39] <arko> i have a few friends at ucla (mostly ee)
[03:39] <arko> great ee program
[03:40] <W6YRA> indeed
[03:41] <W6YRA> i'm going to take off now, keep me posted
[03:41] <arko> will do!
[03:41] <arko> i'll have a write up

[10:03] <eroomde> am super super tempted (through work obviously)
[10:04] <eroomde> it looks a bit 1980s electronics project, but the specs are fantastic, and it's absolutely just the jazz for calibrating instrumentation and data loggers
[10:05] <eroomde> you can fake any bridge type sensor by accurately going up in mV or nV scales, you can look like a fake PT100 temperature sensor by very accurately looking like a certain resistence, and you can fake 4-20mA sensors by very accurately producing those currents
[10:05] <eroomde> it's the bomb, and portable(battery) so you can take it out to the test rig and go around all the sensors one by one on the rocket

[10:20] <eroomde> so jcoxabizzle, you got a scope?
[10:21] <jcoxon> eroomde, i don't and sadly don't have the spare cash to get one
[10:22] <jcoxon> i've used the hackspace one instead
[10:23] <eroomde> you're a doctorator
[10:23] <eroomde> you can afford a scopatron
[10:24] <jcoxon> maybe after christmas

[10:24] <jcoxon> thanks fsphil
[10:25] <Darkside> lawl
[10:25] <eroomde> howsabout a decent soldering iron then?
[10:25] <fsphil> jcoxon: the best kind of nerd
[10:25] Action: jcoxon resists going on a shopping spree
[10:26] <DL1SGP> are there laser beam soldering erm not irons let's call it "equipments" ?
[10:26] <fsphil> I've not bought anything silly in a while
[10:26] <fsphil> but I reallllly need a good psu
[10:26] <eroomde> good soldering irons make electronics fun
[10:26] <eroomde> fsphil: the agilents!
[10:26] <fsphil> too big eroomde
[10:26] <eroomde> well actually i'd get them as a second psu
[10:26] <eroomde> yeah
[10:26] <eroomde> hmm
[10:27] <fsphil> I'd need a shelf or rack for it
[10:27] <DL1SGP> when I get silly I order heavy or large stuff and have it shipped via DHL to home address, cause I do not like the postman and he always gets so annoyed
[10:27] <fsphil> shame too as it's lovely
[10:27] <eroomde> stupid bot
[10:28] <fsphil> hmm odd, they made one that looks like a little house: http://www.ebay.co.uk/itm/Farnell-Advance-Power-Supply-250V-2-5A-in-2x12V-out-/250415748861

[10:28] <eroomde> these old farnell ones are *excellent*
[10:29] <eroomde> however, that's a fair old price for a second hand one
[10:29] <eroomde> though they are much better than similarly priced dodgy chinese stuff

[10:29] <fsphil> aah an analogue one
[10:29] <eroomde> don't let that put youoff
[10:29] <eroomde> they're stabilised and very good
[10:30] <eroomde> they're the sort you use with a decent multimeter if you want to know the actual voltage or current going into your circuit
[10:30] <eroomde> but they're nice and quiet and great for setting 'about 6V'
[10:31] <eroomde> also i like dials for 'seeing' current usage
[10:31] <eroomde> especially with things like micros that have sleep periods
[10:31] <eroomde> they do however make a digital successor to that model
[10:31] <eroomde> we have that at work, it's good
[10:32] <eroomde> if you find one of them on ebay for £100, it's a steal
[10:32] <fsphil> a current usage dial would be nice
[10:32] <fsphil> oh it does

[10:36] chris_99 (~chris_99@unaffiliated/chris-99/x-3062929) joined #highaltitude.
[10:36] <eroomde> which are so so much more psu for the money
[10:36] <eroomde> just, they're big
[10:36] <fsphil> is there a smaller agilent for not much more £ ?
[10:37] <eroomde> there are definitely smaller agilents
[10:37] <eroomde> price is a function of ebay luck
[10:38] <fsphil> mm
[10:38] <eroomde> the classic ones are things like the E364x
[10:38] <eroomde> new they're >£1000
[10:38] <eroomde> might get lucky on ebay though
[10:39] <eroomde> those are dual/triple supplies, which are very useful for analog often
[10:39] <eroomde> (where you want, say +/- 15V for opamps, and 5V for digital)
[10:40] <eroomde> Power Designs stuff (analog) is also super excellent, though not much of it in the UK, lots more in the staes
[10:40] <eroomde> states*
[10:40] <fsphil> ebay's search seem to be getting worse
[10:42] <fsphil> http://www.ebay.co.uk/itm/HP-AGILENT-E3614A-DC-POWER-SUPPLY-0-8V-0-6A-/380778970572
[10:42] <fsphil> little pricy
[10:42] <fsphil> but a good size
[10:42] <fsphil> oh 8V max
[10:44] <craag> I picked up a dual-side Weir 413 a couple of weeks ago. Multi-range 2x30W. Needs calibrating though, the front meters are a couple of V off.
[10:45] <craag> Each side is +(V/2), 0V -(V/2) too. So pretty much a triple for analog stuff!
[10:47] <eroomde> fsphil: they come in loads of flavours
[10:47] <eroomde> usually constant power, tradoff is in max voltage vs max current
[10:47] <eroomde> if you can do +/- 20V, 2A, say, than that should cover you 99% of the time

[11:27] <fsphil> or even 15v to be honest
[11:28] Nick change: KipK -> KipK_away
[11:29] <eroomde> it's useful to have overhead for 15V
[11:29] <eroomde> in as much as for analog stuff you oftn want a nice smooth clean +/-15V rail
[11:29] <eroomde> so you want your PSU to do +/- 20V from which you can have smoothing and linear regs on the circuit down to +/- 15V

[12:09] <gonzo__> navrac_work, I did listed over a few days. Didn't hear anything
[12:10] <gonzo__> thou the keps that gacve didn't seem to be valid, so just too the unisat5 keps and listeded around that time on the omni
[12:10] <daveake> ha https://fbcdn-sphotos-e-a.akamaihd.net/hphotos-ak-prn2/964316_10153553055285088_84234033_o.jpg
[12:11] <navrac_work> I've heard it - but only the slow morse - I couldnt track it because of the doppler except by using sdr-radio - where the keps are out and so its auto doppler tracking was well out using the uosat-5 settings
[12:12] <gonzo__> nowt new under the sun
[12:12] <navrac_work> well the sun used to provoke conversation - well page 3 did
[12:12] <gonzo__> have you reported that? As they would prob like the info
[12:13] <navrac_work> trouble is I didnt make a note of the time....

[12:30] <navrac_work> trouble is as it gets overhead where the doppler is lowest, it falls into the antenna null
[12:31] <navrac_work> but i heard the pips followed by rtty at the right seperation - just couldnt tune fast enough to get more thatn,,3

[20:38] <SpeedEvil> Laurenceb_: I'm wondering about vacuum guages - thermistor ones - what were the smallest thermistors you found?
[20:38] <Reb-SM3ULC> DL7AD_: correct ;)
[20:39] DL1SGP (~DL1SGP@dhcp38.signon1.uk.beevpn.com) left irc: Ping timeout: 252 seconds
[20:40] <Laurenceb_> SpeedEvil: i think 0201
[20:40] <Laurenceb_> but they need cables
[20:40] <Laurenceb_> 0201 was smaller than the smallest leaded stuff
[20:41] <SpeedEvil> yeah - that was about the smallest I found on a quick search
[20:41] <Laurenceb_> Honeywell "TrueStability" differential sensors make the whole thermal idea kind of silly for UAV
[20:42] <Laurenceb_> for blood flow monitoring on the other hand...
[20:42] <Laurenceb_> thats what my PhD is on
[20:43] <Laurenceb_> blood flow has a "flushout" term that is unlike conductivity and heat capacity
[20:45] <Laurenceb_> SpeedEvil: planning to build a FEEP thruster? :P
[20:45] <SpeedEvil> Differential thermal conductivity as a proxy for diffusion?
[20:45] <SpeedEvil> Laurenceb_: Alas, no.
[20:46] <Laurenceb_> vacuum insulation?
[20:46] <SpeedEvil> Laurenceb_: Looking at the hundred quid price of refrigeration guages, and going 'how F*** much'

[20:47] <Laurenceb_> interesting
[20:48] <Laurenceb_> for flow - use a two component heating pad
[20:48] <Laurenceb_> inner disk, ~5mm radius, and outer ring, 5 to 8mm radius
[20:48] <Laurenceb_> heat them to constant temperature offset on skin and look at the ration of power inputs
[20:49] <SpeedEvil> the outer is a 'guard band' ?
[20:49] f5apq (5a014ad3@gateway/web/freenode/ip.90.1.74.211) left irc: Ping timeout: 250 seconds
[20:49] <Laurenceb_> kind of: - after appropriate extended kalman filtering you can isolate the flushout term
[20:50] <SpeedEvil> Laurenceb_: needs moar LAZORS! Massive x/y scanning laser, thermal IR scanner - and now you have a whole-body scanner. Downside - if scanner stalls may melt face off.
[20:50] <Laurenceb_> ive tried that already
[20:50] <SpeedEvil> Oh
[20:50] <Laurenceb_> with high power IR LED and fibre bundle
[20:50] <Laurenceb_> and TMP006
[20:51] <Laurenceb_> works very well, but massive overkill
[20:51] <Laurenceb_> compared to stick on flexi pcb with thermistors
[20:51] <SpeedEvil> :)
[20:51] <SpeedEvil> I was imagining a walk-in box that could do whole body
[20:52] <Laurenceb_> there is another approach
[20:52] <Laurenceb_> flexible thermal flux sensor on the skin
[20:52] vladimirek (~vladimire@95.105.250.72) left irc: Remote host closed the connection
[20:52] <Laurenceb_> then more kalman filtering to find the flow
[20:52] <Laurenceb_> as in periphery (hands etc) at rest, majority of the thermal flux is from the blood
[20:53] <SpeedEvil> hmm.
[20:53] <jcoxon> next stop Gatwick
[20:53] <SpeedEvil> Neat.
[20:54] <Laurenceb_> i prefer the active approach as theres less to interfere
[20:54] <Geoff-G8DHE> Ha Leo put details up on his site in advance ! http://leobodnar.com/balloons/B-32/index.html
[20:56] <Laurenceb_> SpeedEvil: annoyingly these people seem to have a ton of patents
[20:56] <Laurenceb_> http://hemedex.com/products/qflow-500-probe/
[20:56] <SpeedEvil> :/
[20:57] <SpeedEvil> You should never ever be able to get a patent for having a problem.
[20:57] <Laurenceb_> their "probe" is rubbish
[20:57] <SpeedEvil> Only if the solution to that problem requires true genius to solve in a week.
[20:57] <Laurenceb_> heh
[20:57] <SpeedEvil> If an average engineer can come up with the solution in a week, in a well equipped shop - you should be fined for trying to apply for the patent.
[20:58] <jcoxon> I think B32 should float relatively high - doesn't appear to have APRS onboard
[20:58] <Laurenceb_> http://www.faqs.org/patents/inventor/bowman-ma-3/
[20:59] <SpeedEvil> Are these 'obvious' patents?
[20:59] <SpeedEvil> http://www.orionairsales.co.uk/efoy-fuel-cell-212-c.asp - was someone here looking for fuel cells
[21:01] <Laurenceb_> actually the recent ones aren't

[21:18] <Geoff-G8DHE> In essence yes
[21:18] <Laurenceb_> how does it relate to contestia?
[21:19] <Geoff-G8DHE> Only in that Contesia is one of the taged mades

[21:20] <Geoff-G8DHE> indeed, thats what made me think as Leo hadn't changed the mode on th apayload document, and yet it switched atomatically

[22:57] <arko> except i dont think they ran out of helium
[22:57] <DL1SGP> it switched to APRS I guess, Geoff-G8DHE
[22:57] <Geoff-G8DHE> Could be! Hope so!
[22:57] <DL1SGP> if it does aprs
[22:58] <DL1SGP> :D
[22:58] <DL1SGP> m0xer-11
[22:58] <jcoxon> yup
[22:58] <DL1SGP> 36s ago :)
[22:58] <jcoxon> do we think its completely stopped txing on 434
[22:58] <Geoff-G8DHE> Oh good, they just went from 70cms
[22:59] <jcoxon> ?
[22:59] <Geoff-G8DHE> Not a trace here and it wan't weak or anything still goinf s5+
[23:00] <DL1SGP> so let's hope it kicks back in when ceasing APRS over France
[23:00] <Geoff-G8DHE> Actually I should be able to hear it on 144.8 then .... but don't have any ax25 decode in software
[23:01] <Geoff-G8DHE> certainly plenty of packets about
[23:01] M0NSA (~HeliosFA@requiem.soton.gia-lan.co.uk) left irc: Read error: Connection reset by peer
[23:01] <jcoxon> so i've rigged the aprs data to go into B-32
[23:02] <DL1SGP> before trasmitting a packet it should do some approximated R2D2 sound so we can distinguish it from the rest :)
[23:02] <Geoff-G8DHE> Oh hang on another update on 434.5 @ :01:28
[23:03] <jcoxon> no thats me putting APRS data through
[23:03] <DL1SGP> yay
[23:03] <DL1SGP> lol
[23:03] <jcoxon> it should be a continous path of 434 + 144
[23:03] <jcoxon> rather than confusing 2 paths for hte same balloon
[23:03] <Geoff-G8DHE> Its back
[23:03] <jcoxon> oh right
[23:03] <Geoff-G8DHE> it must be switching between bands
[23:03] <jcoxon> do you want me to turn off APRS?
[23:04] <Geoff-G8DHE> hangon until I hear telemetry
[23:04] <fsphil> should be no harm merging them both anyway
[23:05] <S_Mark> They gunna try this SpaceX launch again?
[23:05] <jcoxon> the only thing is if hte aprs trumps the 434
[23:05] <jcoxon> as its got less data
[23:05] <jcoxon> but comes in after the 434
[23:05] <SpeedEvil> S_Mark: they may launch within the hour
[23:05] <Geoff-G8DHE> humm the update on snus says 23:03:41 ???
[23:05] <SpeedEvil> S_Mark: they are unsure and looking at the data gatehred during the abort
[23:05] <S_Mark> Pretty good that they can have an ignition cuttoff and still launch in the window
[23:06] <S_Mark> or attempt anyway
[23:06] <SpeedEvil> S_Mark: they aborted launch as some od the readings from the engines were out of spec
[23:06] <SpeedEvil> Indeed
[23:06] <S_Mark> ah ok yeah I saw the abort and then missed the reason
[23:07] <Geoff-G8DHE> Hum No more pips since what looked like a couple, so no don't take the APRS off! ah pips as I type
[23:08] <Geoff-G8DHE> yes thats B-32 pips
[23:08] <jcoxon> well the aprs script is running on a screen on my account on kraken
[23:09] <jcoxon> so if needs to be stopped either summon me or get a habhub person to kill it
[23:09] <Geoff-G8DHE> well I will loose it at some point tonight so, ah but of course APRS will stop over France again wont it yup telelmetry

[23:44] <adamgreig> they might still have time for one more go
[23:45] <SpeedEvil> Don't think so.

[23:45] <adamgreig> :(
[23:45] <SpeedEvil> Remember - it recycles back to -13 minutes.
[23:45] <S_Mark> Tomorrow possibly if not tonight
[23:45] <S_Mark> I think he said
[23:45] <adamgreig> they got a +20m extension to window and didn't use all the 65m left anyway
[23:45] <adamgreig> but yea it's not a thing you do in a hurry
[23:45] <SpeedEvil> Elon Musk @elonmusk 5m
[23:45] <SpeedEvil> If launch aborts, we will bring the rocket down for engine inspection, so probably a few days before next attempt
[23:45] <S_Mark> ah
[23:45] <Lunar_Lander> hey
[23:46] <Geoff-G8DHE> didn't get the RSID that time and so missed the frame as it was 16/1000
[23:47] <arko> welp, looks like another day
[23:48] <Lunar_Lander> hi S_Mark
[23:49] <Lunar_Lander> adamgreig, hello to you too, I recently came across your website from the arduino boards :)
[23:49] <Lunar_Lander> and I was like "hey I know him" xD
[23:49] <Lunar_Lander> I mean
[23:49] <tweetBot> @stratodean: Hopefully we won't be aborting this time - new launch attempt with Santa on board this Sunday! #ukhas #SpaceX
[23:49] <Lunar_Lander> in the forums some guy asked about cameras & arduino and someone linked to your robot project
[23:51] <adamgreig> oh cool :)

[23:57] <LeoBodnar> I am using rubbish antennas at the moment
[23:57] <LeoBodnar> have not put much thought into them recently
[23:58] <Geoff-G8DHE> right does seem quite a bit down compared to what I was getting with the earlier flights
