[08:40] <daveake> iirc they tried/failed to get the flight doc approved last week but failed as 1 payload doc of 2 hadn't been tested

[08:40] <daveake> they then was tested and he reminded him 2 days ago to get the flight doc approved
[08:40] <daveake> that ^
[08:41] <mfa298> have they been taking lessons from SiS?
[08:41] <fsphil> yeah they're in the water unless it's bursting early

[08:45] <edmoore> well they might land on a sand bank if they're lucky

[08:49] <mfa298> maybe if they're lucky it could make norfolk, but that probably means earlier burst and getting the parachute just right
[08:49] <Vaizki> why did they launch with that kind of prediction? :O
[08:50] <fsphil> they might not have checked
[08:50] <fsphil> or have a boat on standby

[08:59] <swaledale> so RTTY has a good following but the only LoRa is in the chase car I guess
[09:00] <fsphil> they're chasing?
[09:01] <daveake> Going for fish & chips by the sea
[09:01] <Vaizki> yea they're going to the beach
[09:01] <Vaizki> why not
[09:01] <daveake> I've "landed" a payload about where that's going
[09:01] <Vaizki> recover a few seashells
[09:01] <mfa298> that feels like an odd direction to have gone for chasing, but then I
[09:01] <mfa298> dont know oop norf at all
[09:02] <Upu> that chase car is going to have to be that Lotus from james Bond
[09:02] <swaledale> daveake - it's a repeat of where we (alto) landed at skycademy!
[09:02] <Vaizki> I think they are chasing just to get the LoRa images down
[09:02] <Vaizki> not to try and recover
[09:03] <daveake> Yeah, next time (if there is one) I'm going round all the balloons with fish scales to check :)
[09:03] <swaledale> i could have sworn i created a lessons learned powerpoint :/
[09:03] <AndyEsser> Are SkyPi 1 and 2 the same balloon with 2 payloads, or two balloons launched simulataneously?
[09:03] <daveake> Upu That must have been the only Lotus in history not to leak water
[09:03] <Vaizki> AndyEsser, one balloon, 2 radios / payloads
[09:03] <swaledale> andyesser same balloon
[09:03] <AndyEsser> cheers
[09:04] <daveake> Possibly apocryphal story - someone complained to Lotus that he got wet in his Lotus anytime it rained; Colin Chapman sent him a sponge.
[09:05] <mfa298> daveake: pretty sure there is a bit of a leak through the roof showing in the film
[09:05] <daveake> istr that too :)
[09:07] <swaledale> last i saw the car is sat in the bond museum in the lake district. the chap bought pretty much all memorabilia and shoved it all in a few units round the back of the pencil museum!

[09:54] <daveake> Normally one can assume the flight will land short of the prediction, as the predictor assumes sea level. Not this time ...
[09:55] <fsphil> hopefully the lower level winds are a bit slower than it expects
[09:55] <fsphil> it's getting closer to land

[09:58] <Vaizki> ludicrous speed
[09:59] <daveake> 2 minutes storage at full speed
[09:59] <Vaizki> so it's less than 2 minutes of recording at full.. right
[09:59] <Vaizki> dammit
[09:59] <daveake> hah
[09:59] <edmoore> so my new camera does 8fps
[09:59] <edmoore> and each raw file is about 50Mb
[09:59] <Upu> lol
[10:00] <Vaizki> 50MB? :O
[10:00] <daveake> hmmm have we had ssdv from a floating (in the sea) payload yet ?

[10:00] <edmoore> yes they're big-ol files
[10:00] <Upu> you're that problem end user edmoore
[10:00] <Upu> "why has my server run out of space"
[10:01] <swaledale> "why has my cloud run out of space"
[10:01] <edmoore> that's why i put a 1TB ssd in my macbook
[10:01] <edmoore> and even then...
[10:01] <Vaizki> damn.. my 5D3 only does 30-35MB raws I think :O
[10:01] <edmoore> but the files are nice
[10:01] <AndyEsser> we have 100GB proposal files here, that we need to keep all the way back to the start of the universe, I have a constant battle with storage here
[10:02] <edmoore> on the day i got it i just went for a walk with it and the dog at work and even just some shots at a fairly high iso handheld on an overcast day weren't bad - this is just a jpeg out of the camera: http://edmoore.io/images/enke.jpg
[10:02] <edmoore> when it's loaded (it's a big file sorry) look at her eyes on native resolution
[10:02] <edmoore> it's not half bad
[10:03] <AndyEsser> this is like being back in the 90's with limewire waiting for images to downlaod
[10:03] <AndyEsser> :P
[10:03] <AndyEsser> edmoore: good lord that's a fair amount of detail in her eyes
[10:03] <AndyEsser> CSI style "Zoom, Enhance, I can see the murderer"
[10:04] <edmoore> it's not bad is it
[10:04] <AndyEsser> You could do worse
[10:04] <edmoore> on a tripod with a sharp aperture shooting raw, i'm expecting some fun things

[10:06] <Vaizki> the chase car should get a move on if they want to catch the landing position..
[10:06] <pb0ahx> team SKyPi tnx for time was a good flight for me for testing new antenne system here

[10:10] <AndyEsser> edmoore: NSFW watching one of the talks from that playlist I linked yesterday - called "Deeply Embedded C++"
[10:10] <AndyEsser> he's talking about Template Metaprogramming and stuff...
[10:10] <AndyEsser> *shudder*
[10:10] <edmoore> templates are about the only nice computer science idea in c++
[10:10] <edmoore> executed stinkily of course
[10:11] <swaledale> slowing up a little horizontally
[10:11] <AndyEsser> Templates can be powerful and useful - but they're over-used in many places and littered around some codebases I've seen that makes it very difficult to read
[10:11] <Vaizki> landing 400m out to sea is really an insult from lady luck
[10:12] <daveake> Pro tip: if it's 400m or o out to sea, land at low tide with an incoming wind
[10:12] <fsphil> she's not a fan of hashtags
[10:12] <swaledale> many gulls around there? a bird strike could be useful
[10:13] <Rebounder> how annoying if they land 200m offshore..
[10:14] <fsphil> no stations nearby. we may never know
[10:14] <swaledale> this time hiring a boat may actually work!
[10:14] <fsphil> you could swim that
[10:14] <fsphil> well, someone could. I couldn't
[10:15] <Vaizki> oh!
[10:15] <Andrew_M0NRD> losing signal now.. big hill in the way
[10:15] <swaledale> gota be outta range now almost
[10:15] <Vaizki> it's curving up NE
[10:15] <Rebounder> pi-2 running lora or something?
[10:15] <Vaizki> lora and rtty
[10:15] <daveake> a+
[10:15] <Vaizki> let's see how long I get it...
[10:15] <swaledale> needs to step on it and get close
[10:16] <daveake> well it may still tx in water
[10:16] <daveake> depends on how floaty their payload is and where the electronics are
[10:17] <daveake> I feel duty bound to link to my 2nd flight which also had a watery ending :) http://www.daveakerman.com/?p=220
[10:17] <russss> rx in sweden? (!)
[10:17] <edmoore> on the basis that things often swing to the left in the bounday layer, that might slightly bring them ever so slightly inlandier
[10:17] <AndyEsser> daveake: rite of passage isn't it?
[10:17] <Vaizki> I will lose it soon
[10:18] <Rebounder> I like some of the the rtty-receivers are faaaar away :)
[10:18] <Upu> holy crap lol
[10:18] <daveake> yeah, I underfilled as I didn't realise how much the wind affected neck lift measurements
[10:18] <Vaizki> Rebounder, well I'm in Helsinki but using Cleethorpes web sdr :D
[10:19] <Rebounder> Vaizki: i know :)
[10:19] <Vaizki> it will be within 50m of shore at this rate
[10:19] <Andrew_M0NRD> SA6BSS was the last receiver of Eggsplorer1 ;-)
[10:20] <daveake> so close
[10:20] <Vaizki> wow still getting it
[10:20] <russss> land's flat round there
[10:20] <swaledale> not many hills along the coastline :)

[10:23] <Vaizki> SA6BSS-Mike|2, where did that come from?
[10:23] <pb0ahx> congrats guys good flight and a lot of lucky
[10:23] <gonzo_> it's going to be a coin toss. But if not wet, it should be an easy recovery
[10:23] <swaledale> right on the beach i reckon
[10:23] <daveake> First update (if any) may well be on the lora ssdv
[10:24] <Vaizki> Mike's last position puts it 200m inland
[10:25] Nick change: Rebounder -> SM0ULC-Reb
[10:25] <daveake> Yes, but at 237m alt, and with horizontal speed > vertical peed
[10:25] <Vaizki> yup
[10:26] <Vaizki> no mike's is 172m altitude
[10:26] <daveake> ok. very close then
[10:26] <Vaizki> on low tide it might have been dry...
[10:26] <Geoff-G8DHE-Lap> They must have launched before the bacon butties - disgusting!
[10:27] <SM0ULC-Reb> at 172 m height there was 200 to waterline
[10:27] <daveake> yes, but high tide was about 1 hour ago
[10:27] <swaledale> payload is standard polystyrene cube with gaffer around the seam

[10:29] <Vaizki> actually yes I got that packer @ 172m too
[10:29] <swaledale> should have fitted an anchor!
[10:29] <fsphil> that is impressivly close
[10:29] <gonzo_> no excuse not to go and have fish and chips and monitor it till the last
[10:30] <Vaizki> and start of one more packet too
[10:30] <daveake> My mother-in-law lived in Sandilands, very close to the splashdown
[10:30] <Vaizki> it's annoying that the packets start with crap like call sign, sequence and timestamp.. :)

[10:32] <daveake> Nearest chip shop is in Sutton on Sea
[10:32] <fsphil> we need gary's pub suggestion
[10:33] <daveake> For once, I can answer - bar at the golf club :)
[10:33] <Vaizki> I also think it was great that they got LoRa tracking from the car down to 593m altitude

[13:32] <AndyEsser> I need to strap one of my GPS trackers to the cat when I get them ordered
[13:32] <AndyEsser> damn thing went for a wander last night, 2 hours later it rocks up like nothing was wrong
[13:33] <SA6BSS-Mike> our cat was gone for 5 days last year, I was hapy
[13:33] <SA6BSS-Mike> but it came back
[13:33] <AndyEsser> well it's my gf's cat, and the cat has only been at mine about a week, so it's not really "home"
[13:33] <AndyEsser> so wasn't sure if she'd find her way back
[13:33] <AndyEsser> and I couldn't face a hysterical gf
[13:34] <lz1dev> cats always come back to food
[13:34] <SA6BSS-Mike> I have had the same idea, but a tracker with a coin battery on her (the cat) could be fun to se where she goes
[13:34] <AndyEsser> I know you can get collars with them in, but the ones I've seen just store the data and then you have to download it afterwards and it plots a map
[13:34] <lz1dev> local pubs ;p
[13:36] <fsphil> the bbc did this a while back
[13:36] <fsphil> stuck some GPS and cameras on cats
[13:36] <SM0ULC-Reb> AndyEsser: just build a pico-tracker for hte cat ? :)
[13:36] <AndyEsser> with a really tall antenna to get LOS :P

[13:38] <SA6BSS-Mike> guess the cat is within a km or so from home so a small antenna shoukld work, have rotatable yagi on the roof
[13:38] <SM0ULC-Reb> add hysplit to wb8elk?
[13:38] <AndyEsser> SA6BSS-Mike: be easier just to buy a smartphone, but the chase car app on it, and have it send that data via 3g :)
[13:39] <SM0ULC-Reb> :)
[13:39] <fsphil> or just put it in a cage. then you'll always know where it's cat

[13:44] <AndyEsser> haha
[13:45] <SM0ULC-Reb> AndyEsser: what do you have against lora?
[13:45] <AndyEsser> proprietary, primarily
[13:45] <fsphil> it should be gnu/lora
[13:45] <fsphil> I do hope we see either lora get opened up, or a free alternative
[13:46] <AndyEsser> what is it that makes lora so good - and why can't we develop a free alternative?
[13:46] <R34lB0rg> like mp3 vs. ogg?
[13:46] <SM0ULC-Reb> AndyEsser: can understand that.
[13:46] <Vaizki> well I'm sure RTTY was riddled with patents also..
[13:46] <Vaizki> GIF is proprietary :)
[13:46] <fsphil> none of us can make ICs :)
[13:47] <fsphil> lora's biggest advantage is cheap hardware
[13:47] <R34lB0rg> I think JT9 JT65 Contestia Olivia are all equal or better than LORA
[13:48] <R34lB0rg> but someone needs to make an easy to use transceiver chip
[13:48] <mattbrejza> fairly sure you could publish a lora sdr reciever if you find a differnt way to do it as described on the patent
[13:48] <mattbrejza> although im unsure how different it would have to be
[13:49] <R34lB0rg> mattbrejza, you can use the reference implementation from the patent like they did with LAME/MP3
[13:49] <fsphil> and be stuck in patent hell for years like lame was/is
[13:49] <mattbrejza> well yea, perhaps having soruce code on github is also fine, but providing it alongside pits perhaps not
[13:50] <R34lB0rg> yeah, that's why I would prefer an open source transceiver for open protocols
[13:50] <fsphil> nobody's going to make that
[13:51] <R34lB0rg> never say never

[14:32] Action: Ben-AstroSoc dives into datasheet
[14:32] <AndyEsser> you've done something wrong :P
[14:33] <Ben-AstroSoc> yeah we're getting ~65ms
[14:33] <Ben-AstroSoc> not 20
[14:33] <Ben-AstroSoc> which would explain why i couldn't decode anything last week
[14:35] <edmoore> yep
[14:38] <fsphil> that's quite a bit out
[14:38] <edmoore> 65ms is 2^16 microseconds
[14:38] <edmoore> by the way
[14:38] <edmoore> which suggests you might just be getting an interrupt on a counter overflow
[14:39] <AndyEsser> Ben-AstroSoc: fancy showing us your code?
[14:47] <Ben-AstroSoc> fixed the timer issue
[14:47] <Ben-AstroSoc> now gotta get it to decode
[14:48] <AndyEsser> what was wrong?
[14:48] <AndyEsser> share with the class
[14:48] <Ben-AstroSoc> well as of last week i wasn't reloading the reload value
[14:48] <Ben-AstroSoc> so i put in the reload set and uploaded the new code and it didnt work
[14:48] <Ben-AstroSoc> then i realised i hadn't built it
[14:48] <Ben-AstroSoc> >_>.
[14:49] <Ben-AstroSoc> input into dl-fldigi is reaaaaaly messy tho
[14:49] <craag> now go sit facing the corner and think about what you've done
[14:49] <craag> :p
[14:49] <AndyEsser> :P
[14:50] <AndyEsser> Ben-AstroSoc: as in setting it up? or the waterfall is messy?
[14:50] <Ben-AstroSoc> the waterfall
[14:50] <AndyEsser> fiddle with SDR#, reduce/increase the gain (volume slider - top), reduce/increase the bandwidth
[14:50] <AndyEsser> and play with the offset/range/etc sliders on the right
[14:51] <AndyEsser> Also, it doesn't have to be crystal clear in dl-fldigi to work - the waterfall is a visual approximation of something that we as humans can't easily make out
[14:52] <craag> a screenshot may be useful to us Ben-AstroSoc
[14:53] <Ben-AstroSoc> https://usercontent.irccloud-cdn.com/file/pu9zZ6a0/Capture.PNG
[14:53] <Ben-AstroSoc> 2KHz bandwidth right now
[14:54] <craag> Heh that's not too bad to be honest
[14:54] <craag> shift value is too high
[14:55] <Ben-AstroSoc> tried to make the two line up
[14:55] <Ben-AstroSoc> looks good on SDR# but dl-fldigi doesn't like it

[15:50] <adamgreig> good thing they're sealed
[15:50] <Upu> Tikki :)
[15:51] <daey> the tracker batteries, are they usually connected directly to the solarpanel? Or is a battery current/voltage limiter necessary?
[15:51] <edmoore> the thing on the left is fun actually
[15:51] <edmoore> it's a water/moistureproof pressure equalisation valve
[15:51] <edmoore> for all your hab needs

[15:52] <AndyEsser> I'll be in my bunk
[15:52] <daey> edmoore: wasnt sure, because the panels are small and cant deliver much power anyways

[15:53] <edmoore> they'll actually use power
[15:53] <edmoore> so the very very simplest thing is probably just a diode
[15:53] <edmoore> between panel and batteries
[15:53] <daey> yeah, i kind of took the diode for granted
[15:54] <daey> i was thinking in "complex battery loading ics" dimensions
[15:54] <edmoore> and the better thing is probably a little maximum-power-point-tracking circuit with charger circuit suitable for the kind of rechargeable battery you have (but that might be guilding a lilly for initial adventures in hab)

[20:37] <fsphil> daveake wins
[20:38] <daveake> hosler: Why do you think you need 2 callsigns?
[20:39] <daveake> Balloons with multiple trackers have a separate callsign for each tracker
[20:39] <daveake> But if there's just one tracker, using one transmitter, then you just need 1 callsign

[21:07] <daveake> BOC agent in Hereford
[21:07] <MarkIreland> ok
[21:07] <daveake> There's another one south of Ross
[21:08] <daveake> There's an AP place in Hereford too, but they took 30 mins to check my cylinder back in when I used them
[21:08] <daveake> Hopeless. So hopeless they didn't notice I didn't hand back the valve
[21:08] <daveake> Couldn't face another half an hour while they sorted that out
[21:09] <MarkIreland> Ah I'll be sure to avoid them then
[21:09] <daveake> Unless you want an N30 cylinder instead of an N20 (they cocked that up too)

[21:19] <MarkIreland> Mark_B: You thinking more Ross way or the Forest way?
[21:20] <Mark_B> Hi Mark - I'm planning doing a launch which at the moment looks like it'll land in the Brecon Beacons
[21:20] <daveake> EE is very good for 4G here
[21:21] <Mark_B> hurrah, I use an EE Osprey
[21:21] <MarkIreland> Ha I've landed in the Brecon Beacons before
[21:21] <daveake> If you land on a valley over there you probably won't have any signal
[21:21] <MarkIreland> Three was weirdly the best in 2013
[21:21] <Mark_B> was it a good result?
[21:21] <MarkIreland> Yeah it was super hit and miss
[21:21] <Mark_B> stuff of legends
[21:21] <daveake> Yeah 3 generally is good around here
[21:22] <daveake> Don't think they have 4g just yet in Ross
[21:22] <Mark_B> ack
[21:23] <daveake> But 3G is plenty good enough for habbing
[21:23] <Mark_B> thnx fellas, very reassuring
[21:23] <daveake> EE 4G here is about 20/20
[21:23] <Mark_B> wow, that's better than N London 20/10
[21:24] <daveake> Fewer users :-)

[22:39] <MikeUoN> *from
[22:41] <Geoff-G8DHE-Lap> Looks good!
[22:43] <richardeoin> thanks
[22:44] <richardeoin> getting the film is a bit of a pain MikeUoN
[22:44] <richardeoin> it's sold business to business only it seems
[22:44] <MikeUoN> erk, I wonder if I could convince my uni to place an order... Do they have a 'sensible' minimum order size?
[22:46] <richardeoin> They normally deal with things in terms of tonnes or pallets, so the minium orders are pretty big
[22:46] <Lunar_Lander> balloon looks nice :)
[22:47] <MikeUoN> ouch ok O.o
[22:47] <richardeoin> I tried to work out exactly what films would be useful and what wouldn't
[22:48] <richardeoin> and eventually I found a company who told me "er I think we have something like that at the back of the warehouse..."
[22:49] <richardeoin> "we're not sure what it is really, but here you have it"
[22:49] <MikeUoN> oh wow, nice find.

[22:52] <MikeUoN> i think ldpe really doesnt like UV light either... but i guess that's not too big an issue until youre flying for months at a time
[22:53] <MikeUoN> nice website btw
[22:54] <Lunar_Lander> yea :)
[22:54] <Lunar_Lander> and HDPE?
[22:54] <richardeoin> it's jekyll and gh pages goodness MikeUoN :)
[22:54] <Lunar_Lander> sorry just thinking about the first skyhooks being made from PE in the 1940s
[22:54] <MikeUoN> hdpe is bad for permeability too i think
[22:54] <Lunar_Lander> mylar is used today I think
[22:55] <richardeoin> you can watch me make changes if you fancy https://github.com/bristol-seds/bristol-seds.github.io
[22:55] <MikeUoN> Never heard of those richard, I'll admit I'm not very good at the programming kind of things :P
[22:55] <Lunar_Lander> I read the first attempts in the late 1930s used cellophane
[22:55] <Lunar_Lander> and that was really bad in case of UV resistance etc
[22:55] <richardeoin> if it's a big balloon with plenty of gas then ldpe/hdpe is usable
[22:58] <MikeUoN> CAA regs get in the way of the rockoon project?
[22:58] <richardeoin> if you're keen to read up on superpressure ballooning then Dan Bowen's reading list is a good starting point https://docs.google.com/document/pub?id=16vDIgtD8QaEkH2HBYw4JjWhgGNfKUVvYzYoCczVwqzI
[22:59] <richardeoin> The rockoon project was before I joined, so I don't know much about it
[23:00] <richardeoin> the page on it just got migrated from the old google sites thing when we set up the website
[23:00] <MikeUoN> Thanks richard, I'm working on a payload for a final year project - just the payload as I know very little about ballooning aspect :P
[23:00] <MikeUoN> I'll spend a bit of easter on the list
[23:03] <richardeoin> Nice MikeUoN, hope it goes well
