[00:14] <fsphil> Lunar_Lander, they got the altitude record - above 41km
[00:18] <Lunar_Lander> cool!
[00:20] <Zuph> We're about to begin another mission control simulation, if anyone wants to play voyeur.

[00:27] <Lunar_Lander> NigeyS
[00:27] <Lunar_Lander> our altitude line is set
[00:27] <Lunar_Lander> 42 km :)
[00:27] <NigeyS> oh yey
[00:28] <Lunar_Lander> commerical balloons made it to 52
[00:28] <Lunar_Lander> so we can do it too :)
[00:28] <Lunar_Lander> *commercial
[00:31] <Lunar_Lander> we need to find out about their balloon
[00:35] <Zuph> 147000 cubic feet.
[00:35] <Zuph> ZP
[00:35] <Lunar_Lander> how did they get their payload back?
[00:35] <Lunar_Lander> cutdown?
[00:35] <Zuph> Did they? I haven't heard.
[00:35] <Lunar_Lander> oh
[00:35] <Zuph> I know they had a double-redundant HF and VHF cutdown.
[00:36] <Lunar_Lander> but no word about a recovery?
[00:37] <Zuph> Not that we've heart
[00:38] <Zuph> By the way, mission control audio is routing through our ustream now.
[00:38] <Lunar_Lander> do you think we can reach 50?

[02:52] <juxta|console> they're good modules though
[02:52] <juxta|console> so long as you don't manhandle them ;p
[02:56] <fsphil> I just took this one out of the box :p
[02:56] <fsphil> oddly, it has a different default baud rate to the last one
[02:56] <fsphil> 9600 vs 38400
[03:00] <juxta|console> yeah i found they varied too
[03:00] <fsphil> the antenna seems fine too
[03:00] <fsphil> oh it just got a lock
[03:00] <fsphil> that took an hour

[04:24] <juxta|console> what's up?
[04:25] <Zuph> juxta|console: In case you don't know, we're cloning spacenear.us for track.whitestarballoon.com
[04:25] <Zuph> We clone your database into our master database, which gets pushed into our public servers.
[04:25] <Zuph> James has written a script which takes data from our orbcomm telemetry, and puts it into spacenear.
[04:26] <juxta|console> ah right - I'll be setting up a local clone soon too, hehe
[04:26] <Zuph> We're trying to run a simulation, and get that data pushed into spacenear. I deleted wb8elk2 from spacenear earlier today, and I'm wondering whhat I need to do to get new telemetry going.
[04:26] <Zuph> Our fake HF telemetry is working fine, but our fake Orbcomm telemetry is not.
[04:26] <juxta|console> you can submit data as a GET request
[04:27] <juxta|console> assuming you want to post to the tracker directly
[04:27] <Zuph> No, no no, James had a script working which would automatically shove data, and I'm wondering where that is, and how to get that working.
[04:27] <juxta|console> ah right
[04:27] <juxta|console> that I'm not too sure on
[04:27] <Zuph> heh
[04:28] <juxta|console> I can have a look around when I get home, but I'm out at the moment
[04:29] <Zuph> Alright. I'm happy to poke around myself, or if anyone else is awake, I'm happy to poke at them.
[04:30] <NigeyS> with a big stick?

[08:30] <GW8RAK> Bad luck fsphil.
[08:30] <GW8RAK> What a bummer
[08:30] <fsphil> tis
[08:30] <GW8RAK> Any ideas what's wrong?
[08:30] <fsphil> the usual fault with these things is the antenna becoming disconnected
[08:31] <fsphil> or the antenna shield
[08:31] <GW8RAK> Cable come out of the plug/socket?
[08:31] <fsphil> http://www.falcom.de/products/gps-modules/fsa03/
[08:32] <fsphil> nothing so simple unfortunately
[08:32] <GW8RAK> Those modules look very nice, but if they are a bit fragile...........
[08:33] <SpeedEvil> fsphil: yay! (that it failed before the flight)
[08:33] <fsphil> SpeedEvil, good point!
[08:33] <GW8RAK> That is a good point.
[08:34] <GW8RAK> Does the aerial become unsoldered from the pcb?
[08:34] MoALTz_ (~no@92.18.84.154) joined #highaltitude.
[08:35] <fsphil> I think part of the antenna breaks of the solder
[08:35] <fsphil> the solder to the board looks fine
[08:36] <fsphil> I'll try and take a close-up, see if anything is visible
[08:36] <GW8RAK> Sounds like it would be an idea to araldite the antenna to the board on arrival. Albeit a drastic action

[08:46] <jcoxon> got a gpsbee?
[08:47] <fsphil> I do, but not enough time
[08:47] <jcoxon> oh well
[08:47] <fsphil> how far did you get with your faulty fsa03? I remember you took one apart
[08:49] <jcoxon> yeah
[08:49] <jcoxon> it was a bit too tiny to be reliable

[08:51] <jcoxon> well it was an massive balloon
[08:51] <jcoxon> 131000 cubic ft i think
[08:52] <fsphil> they are pushing it my calling it amateur I think, but still very impressive
[08:53] <jcoxon> yes a balloon that size is not actually avaliable to us
[08:53] <jcoxon> the company won't sell it
[08:54] <fsphil> odd.. you'd think they'd be happy to sell
[08:57] <fsphil> robotshop have the gpsbee, ¬49.50 .. not including antenna
[08:57] <jcoxon> i've got 2 spare still

[12:12] <MrCraig> Hi all
[12:13] <MrCraig> I'm about to run out and will be passing both RS and Maplins, so I'd like to buy a couple of components. I need an antenna for the NTX2 and probably for the LasseniQ, I might also pick up a yagi. Can anyone offer tips or point out possible gotchas ?
[12:18] <MrCraig> kk - guess no one is here or has any suggestions .. will cross my fingers and purchase what seems best :)

[12:36] <fsphil> LazyLeopard, ya - it's a no go. the gps module just isn't reliable enough
[12:37] <fsphil> and the predictions for next weekend have it landing in Scotland
[12:37] <LazyLeopard> Rats. No point in launching something you can't find afterwards, though.
[12:37] <fsphil> exactly
[12:37] <LazyLeopard> Hmmm...
[12:37] <fsphil> though I'm tempted to make up a small payload, something I don't mind loosing
[12:48] <groupo> hey guys, wonder if you give a bit of advise?
[12:49] <groupo> im using a fsa-03 for GOS and i hear there is a bit of an issue with it drawing the power it needs from the mega 2560 3.3v pin
[12:49] <groupo> any ideas of something I could use to overcome the issue?
[12:52] <Randomskk> get a normal 3v3 voltage regulator and connect its input to your batteries
[12:53] <Randomskk> if you're in the UK, maybe http://www.rapidonline.com/Electronic-Components/Integrated-Circuits/Voltage-Regulators-LDO/800mA-Low-drop-out-voltage-regulators-LD1117/34991 would work
[12:54] <groupo> Randomskk: cheers man, I am
[12:54] <Randomskk> check that 800mA is enough, but I imagine it would be.
[12:54] <groupo> i will have a look - i have no understading of that pesky thing called electricity
[12:54] <Randomskk> then you'd need to get a 10µF capacitor and connect it to the output, and a 100nF capacitor and connect it to the input
[12:54] <Randomskk> http://www.rapidonline.com/netalogue/specs/82-3064e.pdf is the datasheet for that part - the bottom of page 2 (3rd page of the PDF) has a schematic diagram
[12:55] <Randomskk> Vin goes to your batteries, Vout to the FSA03's 3v3 supply. make sure to connect ground to the batteries, too.
[12:55] <W0OTM> iHAB-3 Launch today at 10AM CST (Preflight/Webcast begins at 9AM) http://www.ihabproject.com/iHAB-3/
[12:55] Gnea (~gnea@unaffiliated/gnea) left irc: Ping timeout: 276 seconds
[12:57] <groupo> I take it there is no way to ensure that the 3.3v is constant coming from the arduino?
[12:57] <Randomskk> what do you mean?
[12:58] <groupo> wll, when you connect the FSA to the arduino 3.3v Vout, it apparently doesnt draw a constant 3.3v
[12:58] <groupo> i was wondering if you could apply an intermediate component to ensure that it does
[12:58] <Randomskk> I don't think it works exactly like that
[12:58] <Randomskk> the arduino supplies 3v3
[12:58] <Randomskk> you can't draw a different voltage
[12:59] <Randomskk> (though very high current consumption will cause the voltage to drop due to internal resistance)
[12:59] <Randomskk> I think the issue is that the FSA03 may draw more current than the 3v3 supply can provide
[12:59] <groupo> hmmm
[13:00] <groupo> that may be it, i think it draws up to 100mA
[13:00] <groupo> and the board only 50mA
[13:00] <groupo> i think
[13:00] <Randomskk> sounds believable
[13:00] <Randomskk> in which case that voltage regulator I linked would work - it provides a separate 3v3 supply of up to 800mA.
[13:00] MoALTz_ (~no@92.18.84.154) joined #highaltitude.
[13:01] <groupo> ok, but i guess u need to connect that to the battery pack separately?
[13:01] <Randomskk> you can use the same battery as is powering the arduino
[13:01] <Randomskk> but you will need to make another connection to it for the regulator, yes
[13:02] <Randomskk> well - the arduino Vin pin connects to the battery, so you could use that if it was a big deal.
[13:02] <earthshine> just give it an external 3v3 supply - batteries via a LM3940 will do it
[13:02] <groupo> ok kl
[13:02] <earthshine> and use an L7805 to drop to 5v
[13:03] <Randomskk> earthshine: he already has a 5v supply from the arduino's onboard regulator
[13:03] <Randomskk> no point chaining a 5v and a 3v3 reg
[13:04] <earthshine> I meant if he was going to use batteries not the arduino supply
[13:04] <earthshine> In which case the LM3940 will be fine
[13:04] MoALTz (~no@92.18.84.154) left irc: Ping timeout: 276 seconds
[13:04] <Randomskk> presumably he's already using batteries to power the arduino
[13:04] <groupo> yeh that was the plan
[13:04] <earthshine> depends if the Arduino output gives enough current
[13:05] <groupo> using some AA's in series and then using the arduinos onboard regulator
[13:05] <Randomskk> well its 3v3 doesn't for the fsa03, which is the issue
[13:05] <Randomskk> hence using a 3v3 regulator also connected to the batteries
[13:05] <fsphil> groupo, be careful when handling the fsa03 - they're fragile beasties :)
[13:05] <groupo> fsphil: i have heard much about this :S
[13:05] <groupo> fingers crossed
[13:05] <fsphil> yea - otherwise they're fantastic little modules

[16:16] <NigeyS> ah that sucks :(
[16:17] <NigeyS> i could send you my funky lassen ?
[16:17] <fsphil> it might work better :p
[16:18] <NigeyS> or you might be there for 6 hours without a lock but hey ... lol
[16:18] <fsphil> the worse part is, it *is* locking fine now
[16:19] <NigeyS> ahh but its being a bit random ?
[16:19] <fsphil> indeed
[16:19] <LazyLeopard> Was satellite geometry funky this morning?
[16:19] <fsphil> I might glue down the antenna now while it's working
[16:19] <fsphil> and send it on a kamikaze flight next weekend
[16:20] <NigeyS> LazyLeopard, unlikely, phils module is having a female weekend lol
[16:20] <fsphil> lol
[16:20] <NigeyS> goes something like this .. "who are you to tell me what to do ........"

[16:20] <NigeyS> ello MrCraig
[16:21] <fsphil> I'm going to request more time for the next notam
[16:21] <MrCraig> heya :)
[16:21] <NigeyS> if you still want to launch phil i do have the locosys gps that ill prolly never use, but its 18k limited
[16:22] <fsphil> you never know when you'll need a gps module
[16:22] <NigeyS> might strap it and a ntx2 to the cat .. lol
[16:23] <NigeyS> see where he buggers off to at 3am!
[16:23] <fsphil> catsnear.us
[16:23] <MrCraig> I bought an antenna for transmission today, said 25-2000Mhz 70cm TX on the packet - I figure that's about right? I'm not sure about the RX though, could I buy something like a high gain tx antenna for that?
[16:23] <MrCraig> tv* not tx
[16:24] <fsphil> sounds like a scanner antenna
[16:24] <NigeyS> lol phil
[16:25] <MrCraig> is that a good thing or a bad thing? lol I'm not up on the antenna tech - I just figured it looked right given the ntx2 spec
[16:26] <fsphil> your best bet is to make one
[16:26] <fsphil> at 70cm antennas are quite small
[16:27] <fsphil> despite the name of the band, the antennas are about 16cm :)
[16:27] <MrCraig> oh so the payload should carry a larger antenna?
[16:27] <gb73d> not bad im having trouble seeting up the rig to rec
[16:27] <gb73d> nothing hrd yet
[16:27] <fsphil> MrCraig, this is what I'm using: http://www.flickr.com/photos/fsphil/5431825038/
[16:28] <MrCraig> I also bought the 18 element tv antenna because it's manual assembly, so I figured if it's unsuitable I can replace the elements
[16:28] <fsphil> that'll work, but not as well as a dedicated 70cm yagi
[16:29] <fsphil> what receiver do you have?
[16:29] <MrCraig> oh, ok, you've just removed the shielding on some coax for the tx
[16:29] <MrCraig> the yaesu ft750
[16:29] <gb73d> winradio g303e
[16:29] <LazyLeopard> MrCraig: where abouts are you, geographically speaking?
[16:29] <fsphil> MrCraig, basically yep. all an antenna is is the properly sized length of conductor
[16:30] <MrCraig> I live just outside london, but launching from cambridge and will be following it in a tracking car
[16:30] <fsphil> ooh, a little mag-mount antenna would be perfect
[16:30] <MrCraig> Launch is only 5/6 weeks away, and still having trouble with the on board software :-( but getting closer
[16:30] <fsphil> stick it on the top of the car
[16:30] <MrCraig> I have a mag mount 4 whip
[16:30] <earthshine> anyone here use the Arduino TinyGPS library?
[16:31] <MrCraig> and a computer installed in the dash of the car
[16:31] <MrCraig> but I don't think the whips will be suitable
[16:31] <fsphil> you'd be surprised -- unless your directly underneath it
[16:31] <LazyLeopard> There are a variety of ham radio shops that should be within striking distance, and they're more likely to have exactly what you need rather than something that might work sort-of...
[16:32] <SpeedEvil> http://www.tesco.com/groceries/Product/Details/?id=270129164 :)
[16:32] <MrCraig> well I hope they'll work because it'll save me pulling over all the time and scanning the sky with a tv antenna! :)
[16:32] <SpeedEvil> I'm half tempted to order it, to see what turns up.
[16:32] <NigeyS> what is it SpeedEvil ? asks me to login :/
[16:33] <fsphil> if your mag-mount antenna is designed for 70cm, it'll probably outperform the tv aerial ;)
[16:33] <MrCraig> http://craigchapman.me.uk/ballooncam/2011/02/the-carputer-and-the-flight-computer/ <- no need to read the blurb, just some pretty pictures
[16:33] Action: SpeedEvil screenshots
[16:33] <fsphil> Love the keyboard!
[16:33] <MrCraig> oh cool - I'll give that a try then - I'll still take the directional as a backup
[16:34] <MrCraig> yeah, the keyb is from a playstation
[16:34] <SpeedEvil> http://www.mauve.plus.com/temp/tesco.jpeg
[16:35] <MrCraig> ok - so the whip I bought for the payload probably isn't suitable, but with a combination of my mag whip, the directional, and a 3G internet connection - I should have tracking more or less covered (though I need to setup the onboard software and aquire help from someone projecting the data to google maps:) - so the only panics I have left are selecting a camera, aquiring the gps antenna, and the flight software.
[16:35] <NigeyS> lol SpeedEvil thats insane!
[16:35] <MrCraig> 5/6 weeks, should be fine
[16:35] <SpeedEvil> I'm half tempted to add it to my outstanding order.
[16:36] <NigeyS> lol do it, you might get a plastic letter "i"
[16:36] <fsphil> MrCraig, if you've time I'd highly encourage some range testing - best not to assume the antenna will work
[16:36] <Laurenceb> heh
[16:37] <MrCraig> *nods - well my problem now is time. If I manage to get this software working today / tomorrow then I'm not too concerned, but otherwise it could become a show stopper.
[16:39] <MrCraig> Will I get away with sending data to the ntx direct from the uart at around 4800 baud?
[16:39] <fsphil> such a high baud rate will limit the range quite a bit
[16:40] <SpeedEvil> Isn't the maximum modulation of the ntx2 10khz?
[16:40] <SpeedEvil> Or is it 50
[16:40] <MrCraig> hmm - then perhaps at this late stage I need to find a chip with dual com ports, because I need to use the baud rate generator at 4800 to receive from the lassen
[16:40] <fsphil> 10kbps
[16:40] <NigeyS> lmao @ obama telling the iss crew to have robonaut make the Tea!
[16:41] <fsphil> Most recent flights use 50 baud, a few use 300 baud
[16:41] <MrCraig> wow, ok - I'm a long way over
[16:41] <fsphil> the slower it is, the better your range
[16:41] <fsphil> so unless you need the data in a hurry, better to go slow :)
[16:42] <MrCraig> ok, this complicates things somewhat. I think I need to use two processors. One to read the gps data, and another to transmit.
[16:42] <fsphil> it's slow enough that you can probably do it in software
[16:42] <MrCraig> possibly software on one of the output pins - it's just timing that could be an issue
[16:43] <MrCraig> I've stuck with the internal osc to minimize components

[19:11] <mattltm> Hiena... Im not so sure about the 4 cell, 5AH, 14.8V lip0 sitting on my desk now :(
[19:11] <fsphil> I've a few lipos around the house
[19:12] <Hiena> Yeah, knowing that last time i cleaned around 5 kg rocket propellant from the workshop and knowing how much Li-Po laying around the desk seems there is no change about the safety level.
[19:14] <mattltm> Athough the ones in the vid were on the end of a 10A charge. I'm no expert but that does seem a little high for a 2 cell?
[19:15] <Dan-K2VOL> fsphil, have you got any plans to find an image type that is tolerant of loss?
[19:15] <fsphil> Dan-K2VOL, I was able to make a few modifications to JPEG to do just that
[19:15] <gb73d> http://www.ihabproject.com/iHAB-3/MissionControl.php
[19:16] <Dan-K2VOL> Mods to the JPEG spec?!?
[19:16] <Dan-K2VOL> Lol
[19:16] <gb73d> u can hear the payload audio on there
[19:16] <Hiena> i guess, they was making sure the explosion. Also if you have 2 x 4000mA cell, and you are a 3D nut on the field, the 10A could be quite common for charging.
[19:18] <fsphil> yep :) each JPEG block (16x16 in this case) is pretty much independent apart from the DC values which are relative to the block before - I changed this so that it stores the absolute DC value
[19:19] <fsphil> a few others changes too, but that's the big one
[19:20] <fsphil> it can now display something even if only one packet is received
[19:20] <NigeyS> blimey still under 50,000ft :|
[19:20] <nv1k> ihab might hit chicago :(
[19:20] <fsphil> I wonder if the chase team will to through Chicago or around it
[19:21] <LazyLeopard> ...and heading for Lake Michigan...
[19:21] <NigeyS> nah at this rate its gonna splash down in lake michigan by the looks of it lol
[19:21] <fsphil> I think it'll clear it
[19:21] <NigeyS> Dan-K2VOL, nice jetstream to the canary isles if you go launch now..lol
[19:21] <nv1k> did they underfill or is it just heavy?

[19:23] <fsphil> Possibly .. I don't remember any of the names

[19:24] <NigeyS> they filmed planet of the apes there iirc .. the original, not the new 1
[19:25] <fsphil> oh, I also got to talk to the pilots on the way there - the view out the front of that plane was incredible
[19:25] <mattltm> Mt Teide was the location of my first near death experiance!
[19:26] <fsphil> the cliffs?
[19:26] <gb73d> im analysing the noise background on the audiospectrumm analyser no lines
[19:26] <fsphil> I remember huge drops right next to the road
[19:26] <mattltm> Cliffs and my dad driving on the wrong side of the road most of the way down!
[19:26] <fsphil> !!!
[19:26] <fsphil> yea I had a similar experience lol
[19:26] <fsphil> could have been the same road
[19:27] <mattltm> You would thing you would learn after 4 near head-ons.
[19:27] <mattltm> But no.
[19:27] <fsphil> four? ooch -- just the one here

[20:22] <fsphil> 50p it clears it

[20:25] <jcoxon> NigeyS, ZP yes
[20:25] <fsphil> maybe, the wrong way
[20:25] <jcoxon> oh right
[20:25] <fsphil> via russia?
[20:25] <NigeyS> yeah
[20:26] <jcoxon> in the summer at a very high altitude very slowly
[20:26] <NigeyS> would be pretty cool to do that

[20:26] <fsphil> oooh ye
[20:26] <fsphil> +a
[20:26] <jcoxon> would be incredibly difficult

[20:26] <Lunar_Lander> another thing that is possible
[20:26] <jcoxon> considering how hard TA with the JS is
[20:26] <Lunar_Lander> is going from the Canaries to Brazil
[20:27] <Lunar_Lander> westward
[20:27] <fsphil> I'm up for the launch team! ;)
[20:27] <NigeyS> where's the jetstream go from here ? i mean, if they get a path from kentucky to the U.K where does it carry on to ?
[20:27] <Lunar_Lander> france probably
[20:27] <Lunar_Lander> or Belgium
[20:28] <fsphil> they sort of twist around the entire hemisphere I think
[20:28] <jcoxon> yeah its usually an W-> E

[20:39] <jcoxon> how?
[20:39] <earthshine> it was just a bad example
[20:39] <earthshine> the code i mean
[20:40] <jcoxon> fair enough - often the ublox modules overfill the buffer
[20:40] <earthshine> it needs a fox before it will work - despite valid strings coming from the module
[20:40] <jcoxon> just need to turn off some strings
[20:40] <earthshine> *fix
[20:40] <earthshine> yeah I have GGA and RMC on only
[20:40] <jcoxon> okay cool
[20:40] <Dan-K2VOL> Heh jcoxon, would gladly launch your payloads if you want to mail them to the middle of the US here
[20:40] <fsphil> I wonder if there'll be an FSA04
[20:40] <jcoxon> Dan-K2VOL, hehe - i might come to GPSL one year
[20:40] <Dan-K2VOL> nice, I've never been able to get off of work for that
[20:41] <jcoxon> yeah i doubt i'd be able to
[20:41] <jcoxon> Dan-K2VOL, how are the sims?
[20:41] <NigeyS> http://habhub.org/predict/#!/uuid=d5759d3a141e7243ab9cc8f6fc1e3bf605782376 ... thats more like it, u.k to germany !
[20:42] <Dan-K2VOL> Its quite a long way from here actually, about 9 hour drive
[20:42] <jcoxon> Dan-K2VOL, it wold be fun though...
[20:42] <Dan-K2VOL> heh yeah it just requires taking time off work, which is tough to do
[20:42] <Dan-K2VOL> Btw did zuph get ahold of you about moving your script to a server?
[20:43] <jcoxon> i emailed him this morning with the script
[20:43] <Dan-K2VOL> Cool, thank you!
[20:43] <jcoxon> i can forward it to you if you want
[20:43] <jcoxon> yeah i'm on call this weekend so its best you guys run it
[20:43] <jcoxon> though i'm happy to 'maintain' it
[20:43] <Dan-K2VOL> No that's alright, I leave the servering to those who do it weel
[20:43] <Dan-K2VOL> Well
[20:43] <NigeyS> on call? :|
[20:44] <Dan-K2VOL> cool, thank you
[20:44] <jcoxon> NigeyS, indeed - oncall
[20:44] <jcoxon> looking after 135 patients
[20:44] <NigeyS> your a doctor ? :o
[20:44] <jcoxon> well i've handed over tonight
[20:44] <jcoxon> indeed
[20:44] <NigeyS> wow didntknow that
[20:45] <jcoxon> allowed me 6 years of uni - hehe
[20:45] <NigeyS> dam thats a long time, did you take a year after sixth form or jump straight in ?
[20:46] <jcoxon> no straight in
[20:46] <NigeyS> blimey, thats like .. 20 straight years of education .. :|
[20:46] <jcoxon> yup
[20:47] <NigeyS> worth it in the end i guess :D
[20:47] <jcoxon> perhaps
[20:47] <jcoxon> the job ain't easy
[20:47] <NigeyS> oh i bet it's not
[20:47] <fsphil> I could definitely not do it
[20:48] <NigeyS> takes special people to do that kinda job
[20:48] <jcoxon> spwecial people :-)
[20:49] <NigeyS> hehe, my mum has looked after disabled children for banardos for 30 years .. plus 4 of her own kids, crazy job !
[20:53] <Lunar_Lander> jcoxon so you are MD or just diploma?
[20:56] <Lunar_Lander> NigeyS btw
[20:56] <NigeyS> ?
[20:56] <Lunar_Lander> I today remembered that Project Strato-Lab did develop a autopilot for ZP balloon
[20:56] <Lunar_Lander> +s
[20:57] <jcoxon> Lunar_Lander, i'm not an MD but I have a MBBS which is the medical degree in the UK
[20:57] <Lunar_Lander> ah I see
[20:57] <jcoxon> MD requires an additional thesis
[20:57] <Lunar_Lander> cool :)
[20:57] <Lunar_Lander> yeah
[20:57] <Lunar_Lander> like a Ph.D. I suppose?
[20:57] <jcoxon> but most Dr in the UK don't have that
[20:57] <jcoxon> yeah
[20:57] <Lunar_Lander> ah
[20:57] <Lunar_Lander> can you maybe help me with a question?
[20:58] <jcoxon> perhaps
[20:58] <Lunar_Lander> I always wondered why a Dr. in science is a Ph.D
[20:58] <Lunar_Lander> and now I saw that there is also D.Sc.
[20:58] <jcoxon> Ph.D is a Doctorate in Philosophy - its a traditional thing
[20:58] <Lunar_Lander> but I think that D.Sc. is given to you when you are Ph.D. and also made some important work
[20:58] <Lunar_Lander> yeah
[20:59] <jcoxon> not sure about D.Sc i've never seen someone with this - i suspect its an indvidual university thing
[20:59] <Lunar_Lander> ah
[20:59] <Lunar_Lander> there is a famous Physicist who is listed on wiki with "Ph.D., D.Sc."
[20:59] <Lunar_Lander> but I forgot who it was
[21:00] SpikeUK (~chatzilla@pdpc/supporter/monthlybyte/spikeuk) left irc: Ping timeout: 240 seconds

[21:00] <Lunar_Lander> damn
[21:00] <Lunar_Lander> it wasn't Thomson
[21:01] <fsphil> I got a job :/
[21:01] <NigeyS> so have i .. lol
[21:01] <mattltm> NigeyS: your with me then but I have to do it via Open Uni.
[21:01] <NigeyS> snap
[21:01] <mattltm> only 4 years left!
[21:01] <fsphil> aah, open uni
[21:01] <NigeyS> physical science
[21:01] <Lunar_Lander> btw I made it
[21:01] <mattltm> Technology
[21:01] <Lunar_Lander> :)
[21:01] <Upu> Meh
[21:01] <Lunar_Lander> I study physics
[21:01] <NigeyS> yeah phil, i left school a dunce..lol
[21:02] <Upu> University was 14 years ago for me :)
[21:02] <Lunar_Lander> did a chemistry course
[21:02] <Lunar_Lander> and now I can do a job in Biological Physics
[21:02] <Lunar_Lander> XD
[21:02] <Lunar_Lander> I mean a student job
[21:02] <NigeyS> hey Upu
[21:02] <Upu> hi NigeyS
[21:02] <Lunar_Lander> hi Upu
[21:02] <Upu> evening
[21:03] <fsphil> would you guys recommend the open uni?
[21:03] <Upu> I'd recommend going to actual uni
[21:03] <NigeyS> i would, but if you lack self discipline, dont bother
[21:03] <Upu> life style and all that
[21:03] <fsphil> nuts - I'm not good with the discipline
[21:03] <Lunar_Lander> is Open Uni only available in the UK
[21:04] <Upu> don't remember much discipline tbh
[21:04] <fsphil> hehe
[21:04] <NigeyS> i wasnt at first, but i forced myself to step away from the PC and the tv and it worked
[21:04] <fsphil> I'd need to make a work area or something, with no distractions
[21:04] <NigeyS> Lunar_Lander, they do offer it for foreign students, not sure of the details mind
[21:04] <Laurenceb> fsphil: my mum did some courses with the open uni
[21:05] <fsphil> I keep looking at the courses now and then, some interesting stuff
[21:05] <Laurenceb> the course material is... different
[21:05] <jcoxon> hmm degrees mean very little imo
[21:05] <NigeyS> they seem to mean less nowadays james :(
[21:05] <Laurenceb> i probably avoid the open uni as their course material etc is too weird
[21:05] <jcoxon> i'm about to collect my MA for not doing anything
[21:05] <Laurenceb> heh
[21:06] <NigeyS> laurenceb i do find it somewhat different to some of the actual uni material ive seen from unis like manchester etc
[21:06] <Lunar_Lander> ah ok
[21:06] <Laurenceb> its quite badly organised and seems to have had a lot of 'post editing' by people unfomiliar with the subject matter
[21:06] <mattltm> I love the open uni. It is a great way for me to study and hold down a full time job.
[21:06] <Laurenceb> NigyeS: you are studing something with the open uni?
[21:06] <NigeyS> yeah, physical science
[21:06] <mattltm> In my filed of work, I am as far as I can go without a degree.
[21:06] <Laurenceb> ah interesting
[21:07] <Laurenceb> mattltm: you as well?
[21:07] <Laurenceb> didnt realise it was so popular
[21:07] <mattltm> Afraid so. Im a "mature" student.
[21:07] <Laurenceb> my mum did environmental science a few years ago
[21:07] <NigeyS> i'm gearing my modules towards astronomy and physics .. but your limited to the route you take which can be a pain
[21:08] <Laurenceb> she got pretty mad with the way the material was structured :P
[21:08] <jcoxon> Laurenceb, i think its very variable
[21:08] <Laurenceb> yeah, i could imagine that
[21:08] <mattltm> I think it would fustrate you if you have been to a FTE uni.
[21:09] <mattltm> But for me it's ideal :)
[21:09] <Laurenceb> yeah its certainly convenient
[21:09] <NigeyS> it is, i found the maths modules to be very oddly laid out, compared to the science module at level 1
[21:09] <mattltm> And I get 4 hours a week paid for by my employers to study at work.
[21:09] <Laurenceb> yeah i have some of the maths module textbooks here
[21:10] <NigeyS> was a shock opening a maths level 2 book when i hadnt studied maths for 14 years!
[21:10] <Laurenceb> they are pretty odd, like they were written by english lit grad students reading wikipedia as a reference source
[21:10] <NigeyS> lol
[21:10] <fsphil> I'd be so bad at math now
[21:10] <NigeyS> i still am

[21:14] <Laurenceb> ah, back when my mum did it there was bbc learning zone
[21:14] <NigeyS> my maths tutor is a physics professor
[21:14] <fsphil> I used to watch that

[21:38] <Lunar_Lander> the Strato-Lab autopilot
[21:40] <Lunar_Lander> want to know how it was supposed to work?
[21:41] <NigeyS> yeah im curious about that
[21:44] <Lunar_Lander> one moment
[21:47] <Lunar_Lander> so
[21:47] <Lunar_Lander> the autopilot had a spinning disk
[21:47] <Lunar_Lander> like a vinyl record with a conducting strip shaped like a spiral
[21:47] <NigeyS> hmm
[21:47] <Lunar_Lander> when the balloon was ascending or descending, the disk was rotating
[21:48] <Lunar_Lander> and when the balloon would have been too fast or too slow, the sensing arm would have left the strip
[21:48] <Lunar_Lander> and in turn would have activated the ballast hopper or the valves
[21:48] WhiteStarMC-171 (~WhiteStar@69.64.6.69) joined #highaltitude.
[21:48] <Lunar_Lander> and at the floating altitude there was a timer set for the float time

[22:29] <Lunar_Lander> back to regulations
[22:29] <Lunar_Lander> anybody know of hazard regulations for HAB?
[22:30] <SpeedEvil> carbon pope
[22:30] <SpeedEvil> oops
[22:30] <Lunar_Lander> lol
[22:31] <Randomskk> Lunar_Lander: the probability is tiny, the consequence severe, the former outweighs the latter and it's consequentially low risk
[22:32] <Lunar_Lander> ah OK
[22:33] <Colin-G8TMV> But note that shining a laser at an aeroplane in flight is considered an act of terrorism - and is treated accordingly
[22:34] <NigeyS> yeah especially green lasers
[22:34] <Randomskk> yea, don't shine lasers at planes
[22:34] <Randomskk> that's a massive dick move
[22:35] <NigeyS> something im well up to date with, as alot of amateur astronomers tend to use them on their scopes
[22:35] <Colin-G8TMV> so what it amounts to is - if you can't control where it's pointing then don't do it
[22:35] <SpeedEvil> NigeyS: easy to avoid though in that case.
[22:35] <SpeedEvil> NigeyS: As planes should be lit
[22:36] <NigeyS> yup, that helps
[22:36] <Lunar_Lander> that is why I asked

[22:37] <Lunar_Lander> but I won't need a laser anyway

[23:03] <jcoxon> Dan-K2VOL, you running a sim this evening
[23:03] <jcoxon> ?
[23:05] <Dan-K2VOL> Yes jcoxon

[23:11] <Zuph> ping jcoxon
[23:11] <jcoxon> hey Zuph
[23:12] <Zuph> Thanks for sending that script along. If I can get cpan working, we can take care of it from here.
[23:12] <jcoxon> okay
[23:13] <jcoxon> if not it runs just fine on habhub
[23:14] <Zuph> Also, is there any way to easily rejigger it so we can insert those batches properly, when we receive 15 at a time?
[23:15] <jcoxon> should be able to very easily
[23:15] <jcoxon> let me have a play
[23:16] <jcoxon> is it worth adapting a php script to allow me to grab the last 20
[23:17] <Zuph> give me 28 seconds
[23:17] <Zuph> the ?latest will no deliver the most recent 20
[23:18] <Zuph> *now
[23:18] <jcoxon> okay
[23:23] <jcoxon> Zuph, okay got it working
[23:23] <jcoxon> well nearly

[23:27] <Zuph> :)
[23:27] <Zuph> Send me the updated script as soon as you like it.
[23:28] <jcoxon> needs a bit of cleaning
[23:33] Gnea (~gnea@unaffiliated/gnea) left irc: Ping timeout: 252 seconds
[23:37] <jcoxon> Zuph, okay so now it pulls the last 20 lines
[23:37] <jcoxon> splits them and individually runs them all
[23:38] <Zuph> Alright, Will dupes be a problem?
[23:38] <jcoxon> no
[23:38] <jcoxon> oooo maybe
[23:38] <jcoxon> i was initially avoiding dupes using the epoch
[23:39] <jcoxon> assuming epoch will go up
[23:39] <jcoxon> but pulling 20 the epoch will go down
[23:39] <jcoxon> now that doesn't matter as we only want new data

[23:42] <jcoxon> hmmm Zuph the issue is how do we reset the script
[23:42] <jcoxon> without just restarting it
[23:42] <jcoxon> or are you happy to fire it up before launch - assuming epoch will just rise
[23:44] <Zuph> Well, that should be the case unless we mis-decode
[23:44] <jcoxon> so before it looks at epoch it checks that the string is valid
[23:44] <Zuph> As long as that can recover from a restart of the script, that should work.
[23:45] <jcoxon> so checks that lat/lon is sensible and that fix = 0
[23:45] <Zuph> And if you want, using ?epoch=XXXX will just return the samples since epoch XXXX
[23:45] <jcoxon> thinking this few dupes aren't an issue at all
[23:46] <jcoxon> so:
[23:46] <jcoxon> we run the script say for 30mins and get 50 points through onto the map
[23:46] <jcoxon> we then for some reason have to restart the script
[23:46] <jcoxon> it'll pull the last 20 and parse them - forward them
[23:47] <jcoxon> actually my thought experiement has revealed issues
[23:47] <jcoxon> :-p
[23:47] <Zuph> hah
[23:47] <Zuph> good :)
[23:47] <jcoxon> so spacenear.us uses server time to plot the points
[23:48] <jcoxon> it compare the strings - if identical it doesn't matter
[23:48] <jcoxon> now for HF thats fine
[23:48] <jcoxon> but remember we are using parsing time to fill in the 'time' element of the string
[23:48] <jcoxon> so if we restart the script the time will be different
[23:49] cory (d0ba23c2@gateway/web/freenode/ip.208.186.35.194) joined #highaltitude.
[23:49] <jcoxon> one solution would be to line up epoch and UTC time
[23:49] Nick change: cory -> Guest84577
[23:50] <jcoxon> or we could allow 'epoch' to be a cmd argument
[23:50] <jcoxon> and then it sets the epoch at that point - only allowing > startepoch data
[23:51] <jcoxon> or that on start up it gets the data parses it all and only accepts the latest epoch point
[23:51] <jcoxon> then gets on with its job
[23:51] <jcoxon> the 3rd option is the most automatic

[23:57] <Zuph> jcoxon: Probably not until after you want to go to bed.
[23:58] <Zuph> If you send me the updated script, I have access to spacenear to clear our test data. Any other housekeeping that needs done?
[23:59] <jcoxon> nope - may need some on the fly editing
[23:59] <jcoxon> as its hard to test - considering i'm testing code to avoid issues with a restart
