[05:54] <KT5TK> Oh, good! On the Pecan board I have the A1 and A2 already on pins. I need to talk to the Arduino to debug the ADF7012 dividers.
[05:54] <UpuHome> I tend to break out A0-A5 as they can be used for anything
[05:55] SelfishMan (~SelfishMa@office.rabidmonkey.org) joined #highaltitude.
[05:55] <UpuHome> do test it though
[05:56] <KT5TK> BTW Upu: The ADF7012 eagle lib that I've stolen from you has the pin 1 dot on the wrong side.
[05:56] <UpuHome> hmm
[05:56] <UpuHome> do you want me to correct it ?
[05:56] <UpuHome> so it should be on the left side by the ADF text ?
[05:57] <KT5TK> If you have a chance. Just thought that this may have caused your desperateness with that chip
[05:57] daveake (~daveake@daveake.plus.com) joined #highaltitude.
[05:57] <UpuHome> no my cause of the desperateness was the pile of external stuff needed to get it working :)
[05:58] <UpuHome> is your solar powered payload still up ?
[05:58] <KT5TK> No it landed and was ewcovered
[05:58] <KT5TK> recovered
[05:59] <KT5TK> The long wire antenna got entangled and wripped off
[05:59] <UpuHome> oh ok its on spacenear.us
[05:59] <UpuHome> as still in the air
[05:59] <UpuHome> I guess I'm ok to delete it ?
[05:59] <KT5TK> therefore it looks like it's hanging nearr 100kft
[05:59] <UpuHome> ah ok
[05:59] <KT5TK> yes sure. Tnks
[05:59] <UpuHome> got a launch in the UK today
[06:01] <KT5TK> Good luck!
[06:01] <KT5TK> what payload?
[06:01] <UpuHome> Its not mine, XABEN
[06:02] <KT5TK> Ah, I see
[06:02] <UpuHome> I updated the library

[07:18] <griffonbot> Received email: MikeB "Re: [UKHAS] RE: Solar Panels"
[07:23] <eroomde> lets invent a non-existant problem and armchair about solving it
[07:28] <fsphil> my tee-shirt has complex patterns and I feel cool wearing it
[07:29] <fsphil> my little PV cell has a largly plastic enclosure, but it's not going be up there long
[07:32] <griffonbot> Received email: Ed Moore "Re: [UKHAS] RE: Solar Panels"
[07:33] <MrScienceMan> my coffee has too much sugar in it
[07:33] <MrScienceMan> if only there were a device to remove the sugar
[07:33] <fsphil> thermal issues only appear if you're silly enough to fly a raspberry pi :)
[07:35] <eroomde> 'lots of internal power to dissipate'
[07:35] <jgrahamc> How power hungry is the pi?
[07:35] <eroomde> coupla watts iirc but daveake is the man to ask
[07:36] <fsphil> it melted some of the polystyrene
[07:36] <eroomde> i think it's the thermal flux out of the usb/ethernet chip that is the issue
[07:36] <MrScienceMan> time to invent a tiny nuclear reactor for HABing
[07:36] <fsphil> yea
[07:36] <fsphil> the RPI model A will lack that chip
[07:36] <fsphil> so will be much better suited
[07:37] <griffonbot> Received email: Ed Moore "Re: [UKHAS] RE: Solar Panels"
[07:37] <eroomde> realised i'd worded it badly
[07:38] <UpuWork> its about 500mA jgrahamc
[07:38] <jgrahamc> Thanks UpuWork
[07:38] <UpuWork> and it smelt of burnt electronics when we opened it up
[07:38] <UpuWork> got very hot
[07:38] <eroomde> @5V = 2.5W
[07:39] <jgrahamc> Interesting. I haven't plugged mine in yet. Although I wasn't planning to use it for a HAB since it has an ugly non-R/T multi-tasking massive operating system in it.
[07:39] <UpuWork> I think the next time will have some more efficient switch mode power supplies on it and use a Model A
[07:39] <UpuWork> ping daveake
[07:39] <eroomde> jgrahamc: no you're confused
[07:39] <eroomde> linux is easier
[07:40] <eroomde> especially when you distrust 'lots of c code'
[07:40] <eroomde> it's much easier to use linux
[07:40] <eroomde> and then have a load of picaxe chips hanging off serial ports
[07:40] <eroomde> you're doing it all wrong
[07:40] <costyn> eroomde: lol
[07:40] Nick change: eroomde -> oliver_de_PhD
[07:40] <UpuWork> PC104
[07:40] <UpuWork> lol
[07:40] <jgrahamc> Ha ha ha oliver_de_PhD
[07:41] <oliver_de_PhD> yes the linux has to be on pc104
[07:41] <oliver_de_PhD> that's also much easier
[07:41] <fsphil> noob electronic question: if I have a capacitor rated at 5V, is it safe to connect it to a 10V source while only letting it charge half way? does that even make sense?
[07:41] <UpuWork> eroomde your "wording it badly" is like me on a really good English day
[07:41] <UpuWork> no fsphil
[07:41] <UpuWork> use a 16v one
[07:41] <UpuWork> or something
[07:41] <MrScienceMan> better us something then
[07:42] Nick change: oliver_de_PhD -> eroomde
[07:42] <jgrahamc> fsphil: my general rule is 'don't fuck with capacitors'
[07:43] <fsphil> hehe, sounds like words of experience?
[07:43] <UpuWork> that rating is how much voltage the dielectric can withstand before allowing DC to pass between the plates
[07:43] <jgrahamc> Wot UpuWork Said ^
[07:43] <UpuWork> you might be able to surge over this for short periods but I would heed jgrahamc's advice
[07:43] radim_OM2AMR (~radimmuti@195.28.91.150) left irc: Ping timeout: 245 seconds
[07:44] <fsphil> ah right, so the initial potential will fry it
[07:44] <jgrahamc> The second rule is: "If you must fuck with capacitors, at least don't do it with electrolytics"
[07:44] <jgrahamc> Electrolytics tend to fight back
[07:44] <eroomde> although they can be an amusing way to try and shoot down a bee that has mistakenly entered the electronics lab
[07:45] <UpuWork> lol
[07:45] <jgrahamc> Also, if you plug in your BBC Micro having left it in a box for years be prepared for the capacitors in the power supply to smoke: http://blog.jgc.org/2011/11/back-from-dead-with-power-supply-repair.html
[07:46] <fsphil> eroomde: or as they call it, the House of the Undying
[07:46] <UpuWork> we see loads of failed caps on motherboards "furry caps" as my engineers like to call them
[07:47] <eroomde> sounds like a mushroom
[07:47] <fsphil> I've had two a-bit motherboards with cap problems
[07:48] <eroomde> there was a big thing a couple of years ago iirc where many tens of thousands of motherboards were affected by a dodgy batch of electrolytic caps
[07:48] <UpuWork> yeah the fake ones
[07:48] <fsphil> yea this was one of them
[07:49] <eroomde> fsphil: if you want longer life or more robust caps, tantalum caps might be worth considering
[07:50] <eroomde> they are also surface mount usually which means one less soldering operation (i.e. done in the oven cycle rather than the post-oven individual pth cycle)
[07:50] <eroomde> which makes me happy
[07:50] <eroomde> they also have some really low internal resistances
[07:51] <fsphil> this is for the solar beacon, so low internal resistance is good++
[07:51] <eroomde> they have good temp ranges too
[07:52] <eroomde> i use sanyo's poscap range a lot
[07:52] <eroomde> for things like switch mode power supplies
[07:52] <fsphil> I've used them on my flights so far for the temperature range
[07:53] <eroomde> they're a bit spendy though atm as someone realised tantalum is a conflict mineral and everyone is having to comply with new laws to source ethically
[07:53] <eroomde> i must pop out for a jog or today will never happen
[07:54] <eroomde> bbl

[08:24] <daveake> pong UpuWork
[08:26] <daveake> Ah, re the Pi ... yeah, a model B plus webcam runs at 500mA idle and a bit more when the webcam is in use. model A will allegedly be <=200mA
[08:27] <daveake> PIE1 had a linear off-board reg with 6AAs, so total power was 4-5W depending on battery voltage
[08:28] <daveake> On the Pi, most fof the heat comes from the USB/ETH chip and the next most is the 3V3 regulator.
[08:28] <jgrahamc> Thanks
[08:29] <daveake> I'm currently running my model B from 2 switching regulators, one for the 5V (which is basically just the webcam) and one for the 3V3
[08:29] <costyn> daveake: speaking of regulators, what reg would you recommed for a 3.3v pro mini?
[08:30] <daveake> And with those regs, the whole thing is running at around 2W
[08:30] <daveake> And the model A will halve that, roughly
[08:30] <griffonbot> Received email: Mike Bessant "Re: [UKHAS] RE: Solar Panels"
[08:30] <daveake> The 3V3 mini pro has its own reg, and a very good one it is too
[08:30] <costyn> ok good
[08:30] <costyn> thx
[08:31] <daveake> It has a very low dropout voltage - something like 0.2V at 100mA IIRC
[08:32] <daveake> I've had an entire tracker running down to about 3.1V going in to the reg before it stops
[08:32] <costyn> nice
[08:32] <fsphil> hmm.. the big caps I have are only 2.5v, and the panel is 5v. plan B :)
[08:33] <daveake> So I'm quite happy running one from 3 cells. I get about 15 hours from AAAs, in the freezer, on a tracker with mini pro / rfm22b / ublox
[08:33] <costyn> daveake: very nice
[08:34] <costyn> going to try my hand at my own 3.3v tracker with those components
[08:35] <costyn> should be a nice challenge
[08:37] <daveake> One I did - http://www.daveakerman.com/?p=277

[10:07] <daveake> I see my maths is wrong; need caffeine :D
[10:07] <eroomde> I just need caffeine
[10:07] <eroomde> not had any yet today
[10:08] <eroomde> makes me grouchy

[10:08] <eroomde> no not poor josh
[10:08] <costyn> daveake: whats wrong with the maths?
[10:08] <eroomde> i can have the clarity of solomon and still conclude that he's a cize prunt

[10:09] <daveake> But I was in a rush to finish typing that as the phone was ringing
[10:10] <costyn> didn't realise it was so easy to measure voltage with an analog port
[10:10] <daveake> He does need a bit of a reality check
[10:11] <eroomde> as jgrahamc pointed out, some people are inherently impervious for reality checks
[10:11] <daveake> Seems to think that making a box with ink in it is an achievement.

[10:12] <daveake> that's very true
[10:12] <jgrahamc> Thanks daveake
[10:14] <jgrahamc> Actually josh's first flight was "quite possibly be the best and most exciting weather balloon flight EVER to have taken place"
[10:15] <jgrahamc> Great comment on my blog about my Mars rover post:
[10:15] <daveake> riiiiiiiiiiiiiiiiiiiiiight
[10:15] <jgrahamc> "John, when a single geek does what you propose on a shoestring budget with much higher image quality and even bandwidth despite not having access to a satellite network like nasa could have done, will you then wake up and realize how pathetic nasa is? what Curiosity is doing would not be out of place in 1970. it is that pathetic. indeed it could be outdone with live video in 1970"
[10:15] <daveake> jeez

[10:18] <eroomde> oh oh oh

[10:19] <jgrahamc> No, eroomde, you should reply to this one:
[10:19] <jgrahamc> "My approach would be different: build and launch an entire horde of small, inexpensive robots which can fix each other, scavenge on each other for parts, and collaborate on various tasks. Sort of deploying a mobile cloud, instead of a single powerful server, in terms of software. It would be a real challenge for the software developers, but not really that much of a challenge for the hardware developers, IMO. Comming to t
[10:19] <eroomde> anything packaged slightly pompously had better be totally water-tight
[10:19] <jgrahamc> lus a lego mindstorm make a good prototyping platform for prototyping ..."
[10:19] <eroomde> haha that's amazing
[10:19] <eroomde> when all you have is a hammer...
[10:20] <hitman_> hi guys , has anyone had problem when using the same power source for the Ublox 6 and the NTX2 ? The signal looses strength when they are powered together for me
[10:21] <daveake> What's your power source? i.e. what regulator?
[10:21] <hitman_> im powering it using my computer at the moment because im still prototyping
[10:22] <hitman_> computer to cable to arduino uno
[10:22] <eroomde> hitman_: that is quite plausible.
[10:23] <daveake> So running from the 3v3 reg on the Uno?
[10:23] <eroomde> I would say that it's not *inherently* a common power source that is the problem
[10:23] <daveake> The one that is 50mA max?
[10:23] <eroomde> but given they are on the same circuit, if there are grounding issues and emi issues, the gps will be affected
[10:23] <hitman_> no 5v ?
[10:23] <daveake> Whena ublox uses 50-120mA?
[10:24] <eroomde> oh yes i see where daveake is going and that's plausible too. i have no idea what the 3v3 reg on an arduino can do
[10:24] <hitman_> ublox uses 65mA
[10:24] <jonsowman> if it's the FTDI chip supplying the 3V3 then it's a few mA max
[10:24] <eroomde> but in general hitman, don't have the gps and the radio ground plans / ground tracks right next to each other.
[10:24] <hitman_> ok
[10:25] <jgrahamc> You can only have 50mA from the 3.3V pin on Arduino Uno
[10:25] <eroomde> but go with daveake's line of enquiry first because mine is more handwavy general principles and i suspect daveake as specific experience doing this with 3v3 arduin pro minis
[10:26] <daveake> hitman It's not as simple as "ublox uses 65mA" ... it depends on the lock for a start and it uses lots more before it gets a lock. Even then the power usage is quite spiky.
[10:26] <jonsowman> even if it were 65mA that's still >50mA

[10:26] <daveake> it is :)
[10:26] <daveake> and the NTX2 uses another 20 I think
[10:27] <hitman_> yes . hw would u suggest i power it up ? NTX2 is 20mA
[10:27] <jonsowman> dedicated 3V3 reg
[10:27] <daveake> Add a regulator for the ublox
[10:27] <hitman_> ok
[10:27] <fsphil> jgrahamc: wow, someone actually took time out to write that?
[10:27] <jonsowman> the LM1111117 is fairly popular and easy to use
[10:28] <daveake> The NTX2 has its own regulator so that can be powered from a higher voltage if you like
[10:28] <eroomde> haha ok jgrahamc

[12:06] <Upu_M0UPU> tbh Captain_Beefhear I have an AZ/El and its currently pointing towards Cambridge way and the payload is out of its 15' "beam width" but is still decoding right

[12:15] <daveake> spacenear is lagging behind
[12:15] <Laurenceb> altitude seems broken
[12:15] <Laurenceb> something seems screwed with the map
[12:15] <daveake> Yep
[12:16] <daveake> Last update on the map is 5 mins ago
[12:16] <Upu_M0UPU> max altitude is updating though
[12:16] <Laurenceb> xaben1 off
[12:16] <daveake> Yes
[12:17] <Laurenceb> map not updating
[12:17] <Laurenceb> somethings broken
[12:17] <daveake> logtail seems happy
[12:17] <daveake> I have a local map here which runs off logtail, and that's updating just fine

[12:21] <Adam__> whats the frequency for xaben?
[12:21] <Upu_M0UPU> Looks like XABEN restarted hence the issue DanielRichman is fixing now
[12:21] <daveake> Ah, I thought the sentence count looked a bit low
[12:23] <Adam__> Xaben uploading again
[12:23] <DanielRichman> yup sentence count reset from 200 to 1 at 11:41:40 utc
[12:23] <DanielRichman> have added 400 to it
[12:23] <DanielRichman> should do the trick for now
[12:23] <Adam__> how can i try and get my sdr dongle to try and tune in to it?
[12:23] <Adam__> whats the current freq?

[12:30] <Adam__> ah my aerial isn't good enough to pick it up :(
[12:30] <Adam__> thought the mag mount might do it..
[12:31] <fsphil> it would, but it's probably not high enough up

[12:33] <fsphil> and see the two lines on the waterfall
[12:33] <Adam__> i'll try and get the aerial higher
[12:34] Action: LazyL_M0LEP han hear both here now. Tracking the second at present...

[12:34] <Adam__> there is a definate peak on 434.075, but when i center it there it's just noise..
[12:34] <Adam__> ok
[12:34] <fsphil> you'll see two signals
[12:34] <LazyL_M0LEP> DrLuke: Gives sytems time to lock oon.
[12:34] <DrLuke> ah
[12:34] <LazyL_M0LEP> Actually, 4 or 5 isn't that many.
[12:35] <Adam__> yes there are two peaks
[12:35] <Adam__> but no beeps when i go onto them

[12:48] <_2e0sql> Hi guys I've downloaded DL-Fldigi but no idea what todo next
[12:48] <Captain_Beefhear> That lift in the middle is DC.
[12:48] <_2e0sql> pretty strong signal on 434.075
[12:48] <fsphil> hiya _2e0sql
[12:49] <fsphil> have you started it in HAB mode?
[12:49] <Adam__> yes
[12:49] <Adam__> and auto configured to XABEN
[12:49] <MickMondo> Yep perfect from southend On Sea
[12:49] <Upu_M0UPU> Adam do you want me to take a look ?
[12:49] <Upu_M0UPU> hey MickMondo :)
[12:49] <MickMondo> Hi ya
[12:49] <Upu_M0UPU> I'm on support atm can use our LogMeInRescue and take a look
[12:49] <Adam__> What do you mean Upu?
[12:49] <_2e0sql> fsphil: no, how does one do that?
[12:49] Action: LazyL_M0LEP is back on XABEN to balance up the number of trackers on each a bit...
[12:49] <Upu_M0UPU> I can remote control your PC and have a look
[12:49] <fsphil> _2e0sql: after installing it you should have two icons in the start menu for dl-fldigi
[12:49] <fsphil> start the one that says HAB mode
[12:50] <Adam__> My internet is laggy, but we could try if you're OK with that?
[12:50] <Upu_M0UPU> sure PM
[12:50] <_2e0sql> fsphil: ok in HAB mode
[12:50] <MickMondo> Valve open .. is that a dump valve ..?
[12:51] <fsphil> _2e0sql: you should see a dropdown list on the top left with a list of active flights
[12:51] <fsphil> select the one you've currently tuned into, and press "Auto-configure"
[12:52] <fsphil> that should set all the rtty parameters (though you might have to adjust the shift manually)
[12:52] <_2e0sql> Yep its doing it
[12:52] <MickMondo> anyone know what the valve open valve closed is .... or is it from some other project
[12:52] <Captain_Beefhear> Adam - you are using a TV dongle. You won't see it in that bandwidth. You need to narrow down.
[12:53] <fsphil> you should see the telemetry decoding on the screen, and if it gets a full string with a valid checksum the bar along the top should turn green
[12:54] <_2e0sql> fsphil: every time Phil
[12:54] <fsphil> I didn't have time to head home and plug the fcd in
[12:55] <_2e0sql> hehe
[12:55] <daveake> MickMondo From another project I'm pretty sure. I've seen that before.
[12:55] <_2e0sql> quickly turned on the IC-910 as there wasnt a satellite pass
[12:55] <_2e0sql> fsphil: i think i've set it to forward data online but 100% sure
[12:55] <fsphil> yea I see you in the list of receivers
[12:56] <MickMondo> Hi Dave .. cheers
[12:57] <_2e0sql> fsphil: its about 57-59 bit of flutter
[12:57] <fsphil> I wonder what RocketBoy is up to, launching two :)
[12:57] <fsphil> what sort of distance from you _2e0sql?
[12:57] <MickMondo> he wants the altitude record back ...lol
[12:57] <fsphil> I imagine you've got a nice setup for doing satellites
[12:57] <daveake> At a guess, 1 commercial one to beat Mick :p
[12:57] <fsphil> lol
[12:57] <_2e0sql> 50miles or so to the north of me
[12:57] <fsphil> I'll have a go at that record one of these days
[12:58] <_2e0sql> fsphil: hah 10el yagi got it at about 30 degrees elevation
[12:58] <fsphil> wow
[12:59] <fsphil> you'd probably have enough gain for decoding 1200 baud telemetry
[12:59] <daveake> Records are only temporary. One of mine lasted 5 mins 40 secs :)
[12:59] <fsphil> that itself was a record
[12:59] <_2e0sql> fsphil: yeah thats easy enough
[12:59] <daveake> Good point :D
[13:00] <fsphil> I'll do a 1200 imaging flight too some day
[13:00] <fsphil> switch to 300 on the way down
[13:00] <Captain_Beefhear> What is the lowest altitude record for a burst - or are we keeping quiet about that?
[13:01] <fsphil> not counting failed launches, good question
[13:02] <fsphil> the lowest altitude on the record table is 3291.84m
[13:02] <fsphil> http://ukhas.org.uk/general:uk_records

[13:18] <MickMondo> they both look good
[13:19] <Laurenceb> 30km
[13:19] <Captain_Beefhear> Look like they are heading for a mid air collision. Chase car on the move now. Presumably it contains a boat.
[13:19] <MickMondo> the signal from here is really good
[13:19] <daveake> Looking at the alt plots, I summise that xaben is a full-fat payload and xaben1 a H2 light one
[13:20] <daveake> xaben was doing over 7m/s warlier
[13:20] <Captain_Beefhear> Or it could be the lower weight of the shorter message strings stored there
[13:20] <MickMondo> yeah I was guessing that, 434,300 too
[13:21] <MickMondo> any idea of the weight dave...?

[13:43] <daveake> IIRC Steve's record flight did land in a tree. That was when he and I both had attempts on the same day. His went up quickly and landed in a tree not far from where Number10's flight landed. Mine floated and landed near Nottingham
[13:44] <number10> if, I was a little faster getting payload ready his wouldnt have landed in the tree :(
[13:45] <daveake> So can I blame you for the one that landed a mile off Cromer? :p

[13:46] <daveake> Ah yes, I remember passing near your landing spot on our way to the seaside
[13:46] <daveake> 1 mile out; still transmitting; tide took it further
[13:47] <number10> you can blame yourself for underfilling on that one ;)
[13:47] <daveake> I'll blame Steve's filler then :D

[13:50] <eroomde> i think i or someone in cusf borrowed is red pliers once in 2006, then he couldn't find them
[13:50] <eroomde> it was about 2008 before he stopped bringing up the red pliers

[13:53] <MickMondo> Yes you did dave, sorry
[13:54] <Upu_M0UPU> 27k death zone
[13:55] <MickMondo> yeah past .. ha ha
[13:55] <MickMondo> its looking good
[13:56] <MickMondo> what do you reckon M0UPU
[13:56] <Upu_M0UPU> says Mick nervously
[13:56] <MickMondo> lol
[13:56] <Upu_M0UPU> tell you when it exceeds 42.5km
[13:56] <daveake> :)
[13:56] <daveake> Well once past the 27km anti-woo-woo zone, it should be good for 42km+
[13:57] <MickMondo> its all good fun though
[13:57] <daveake> It is indeed
[13:57] <LazyL_M0LEP> XABEN getting a bit faint here now...
[13:57] <daveake> Roll the dice and see what happens.
[13:58] <MickMondo> signal still amazing here
[13:58] <daveake> Very good here for 3km
[13:59] <Captain_Beefhear> It would be 100% here if it were not for a local data transmission on frequecy
[13:59] <LazyL_M0LEP> Seeing something but not decoding enough to make sense...
[13:59] <MickMondo> still good but fading
[14:00] <Penfold> signal would probably be pretty awesome here, once I get round to having a licence and he appropriate kit :D
[14:00] <fsphil> you can get the kit before the license :)
[14:00] <jgrahamc> Don't need a license to be a listener
[14:00] <Penfold> it's about 10miles from me tops at present
[14:00] <jgrahamc> Owning and receiving on amateur radio equipment is OK without a license.

[14:17] <Captain_Beefhear> or whatever that diagonal path across the field is.
[14:17] <Laurenceb> seem to have lost chase car
[14:17] <Penfold> from memory it's a footpath
[14:17] <Laurenceb> 35Km
[14:17] <Captain_Beefhear> That would be helpful.
[14:17] <Laurenceb> ?! memory
[14:18] <MickMondo> whats signal like where you are dave
[14:18] <daveake> Nice and clear, if a bit wobbly
[14:19] <Penfold> half-tempted to duck otu early and go take a look
[14:19] <MickMondo> lost it here
[14:19] <Captain_Beefhear> Yes, nice and clear. There is a transmission just above it but not interfering
[14:19] <MickMondo> its back
[14:23] <Captain_Beefhear> I am surprised Dave gets suc a good signal with just a vertical and an FCD.
[14:24] <daveake> And a filtered pre-amp
[14:24] <daveake> To be fair, the FCD is very good
[14:25] <Upu_M0UPU> HABAmp
[14:25] <Upu_M0UPU> I think my colinear is in a null
[14:25] <Upu_M0UPU> ah it's coming back
[14:25] <Captain_Beefhear> Ah -must send my £20.
[14:25] <Upu_M0UPU> yes if you're on the list and want one let me know
[14:25] <daveake> I've got a yagi in the loft, connected to an 817, and that's doing just as well without a HABamp
[14:26] <Captain_Beefhear> But I got loads of QRM with the omni. A beam hels cut it out, a little

[15:09] <DrLuke> actually a parafoil is suboptimal
[15:09] <DrLuke> depending on the wind speed you can only really move in one direction
[15:09] <DrLuke> no matter which way you're heading
[15:11] <costyn> true, if it's a small parafoil with a light load beneath it

[17:40] <Lunar_Lander> well that looks like a serious problem
[17:40] <Lunar_Lander> or hopefully just a temporary GPS error
[17:40] <daveake> eh?
[17:41] <Lunar_Lander> while the latitude is correct, the longitude my GPS measured today is about 20 km eastward
[17:41] <daveake> Oh, on your tracker?
[17:41] <Lunar_Lander> yea
[17:43] <Lunar_Lander> also the navmode jumped around 47 and 54
[17:43] <Lunar_Lander> there must be some error there
[17:45] <Lunar_Lander> daveake, the payload is OK I think
[17:46] <Lunar_Lander> it heated up to 45 °C and then cooled exponentially (I still have to check but I assume that cooling set in when the camera shut down

[17:48] <Lunar_Lander> we want to have airborne mode, indicated by a 6
[17:49] <bertrik> ah ok
[17:51] <bertrik> the other mode could indicate degraded modes, like not enough satellites in view so it does some assumption (e.g. height staying the same)?
[17:51] <Lunar_Lander> the mode it is in by default is called "Pedestrian"

[22:11] <DanielRichman> slightly fsphil- for payload_telemetry I think the only change is the date format is going from unix timestamp to rfc3339
[22:11] <daveake> All I wanted was the same telemetry string, but from habitat, in case I missed it in the car
[22:11] <DanielRichman> daveake: aah, ok
[22:11] <DanielRichman> which language is it written in?
[22:11] <daveake> But then the car app begat a base app and that's still doing the same thing
[22:12] <daveake> Delphi (aka Object Pascal)
[22:12] <Randomskk> daveake: did the recent change to the HTML formatting of logtail mess your thing up?
[22:13] <Randomskk> or do you grab the log direct/
[22:13] <Randomskk> I guess the latter
[22:13] <DanielRichman> the couchdb website doesn't list any couchdb libraries for delphi, which is a bit :-(
[22:13] <DanielRichman> it's just json though so
[22:13] <Randomskk> on the other hand you do just have to hit a URL and parse JSON
[22:13] <daveake> Briefly because my code thought that any "long" line was going to have a timestamp :p
[22:13] <daveake> Fixed that when I saw it
[22:14] <daveake> It's OK I'm quite happy to parse the JSON
[22:14] <Randomskk> daveake: with a json parsing library right? :P
[22:15] <daveake> Of course :p
[22:15] <Randomskk> there's a view you can hit up that makes it all quite nice
[22:16] <fsphil> be great if you could make a 'current activity' view, that includes the current flights from the launch position
[22:16] <Randomskk> from the launch position?
[22:17] <fsphil> yea. spacenear.us caches the data locally
[22:17] <Randomskk> not sure what you mean
[22:17] <fsphil> yea, bad at explaining things
[22:17] <fsphil> when I start habhound, it's blank
[22:18] <fsphil> some way to fetch the current view (like spacenear.us) would be nice
[22:18] <Randomskk> oh, as in fetch all the current telemetry and so forth?
[22:18] <Randomskk> interesting
[22:18] <fsphil> yes
[22:18] <Randomskk> spacenear gets cleared manually
[22:18] <fsphil> aye
[22:18] <Randomskk> I don't know how exactly you'd have your app manage it
[22:18] <Randomskk> but for instance
[22:18] <Randomskk> you could easily fetch all the currently active flights
[22:18] <Randomskk> (there's a view for that)
[22:18] <fsphil> habitat has the data on current flights
[22:18] <Randomskk> and for each flight, fetch all the telemetry for them
[22:19] <Randomskk> wouldn't take much
[22:19] <fsphil> ah ha
[22:19] <fsphil> that would work
[22:20] <fsphil> so I'd query current flights, is there a view to get telemetry for each of those flights then?
[22:20] <daveake> "Current" would be good. In the chase car, I really only want "current at my launch site" but I could easily get "current" and select from that list, then have the program only download data for those
[22:20] <Randomskk> there's a view to get telemetry by flight: http://habitat.readthedocs.org/en/latest/habitat/habitat/habitat/habitat.views.payload_telemetry.html#habitat.views.payload_telemetry.flight_payload_time_map

[22:20] <Randomskk> somewhat stupid URL, sorry
[22:21] <Randomskk> habitat/habitat/habitat/habitat.views... :P
[22:21] <Dan-K2VOL> oh I hear ya
[22:21] <daveake> nice :p
[22:21] <Randomskk> daveake: you could just show the current flights as a list
[22:21] <fsphil> the habitat habit
[22:21] <Randomskk> and then select one
[22:21] <Dan-K2VOL> my IRC client reads the room text aloud, I usually hit mute when I hear http:
[22:21] <Randomskk> daveake: hehe
[22:21] <Randomskk> uh
[22:21] <Randomskk> Dan-K2VOL: hehe :P
[22:21] <fsphil> lol
[22:22] <daveake> Randomskk I think that's what I said (or meant anyway!)
[22:22] <Randomskk> daveake: I mean, it shows the flight list, but doesn't load data for all of them, just waits for you to select one
[22:22] <Randomskk> which may well be what you said :P
[22:22] <daveake> exactly what I meant :D
[22:22] <Randomskk> oh
[22:22] <Randomskk> that is exactly what you said, too, I just failed at reading :P
[22:22] <Randomskk> yea so that'd be easiest I think
[22:22] <daveake> lol
[22:23] <Randomskk> fsphil/daveake: worth bearing in mind that the views documented there are for the very-nearly-almost-ready new database format
[22:23] <Randomskk> the current (unstable) (beta) database format doesn't have documentation for its views really
[22:23] <daveake> ok
[22:24] <Randomskk> the new (stable) one is well documented
