[02:04] <SpeedEvil> The licence fee goes towards the BBC, basically.

[04:46] <grayhatpython> Hi i i am doing a balloon project with a group of friends. I came to know about dual balloon Atlas project but i didn't find the images of the attachment of two balloons but i have seen that text graph. Can you please explain me how it works?

[04:47] <grayhatpython> i mean i want the design
[04:49] <grayhatpython> my friends say dual balloons will be imbalance when they reach high altitude. anyone there?
[05:07] <Pavix> Hmm, I heard the same thing
[05:07] <Pavix> I was also told that they won't gain you any additional altitude
[05:12] <grayhatpython> thanks for the reply
[05:13] <Pavix> No problem, it can get quiet in here off and on
[05:13] <Dan-K2VOL1> hello grayhatpython
[05:13] <Dan-K2VOL1> and pavix
[05:13] <grayhatpython> can anyone show me the pics about the atlas project. i want to see how they attached the two balloons to the payload?
[05:13] <Pavix> Howdy
[05:13] <grayhatpython> Hi dan
[05:14] <Pavix> http://ukhas.org.uk/projects:atlas
[05:15] <Pavix> There's a diagram
[05:15] <grayhatpython> yes i have seen the diagram but i want the real pics
[05:15] <Dan-K2VOL1> I'm not sure about how they did that, but here's the picoatlas! http://www.youtube.com/watch?v=VjpzSRefPeQ
[05:16] <Dan-K2VOL1> grayhatpython I've flown dual balloons before, I can guess that they just tied two equal length strings both to the ropes that crosses the parachute center hole
[05:17] <grayhatpython> how it's different from single big balloon?
[05:18] <grayhatpython> the video has three balloons right?
[05:20] <Dan-K2VOL1> yes
[05:20] <Dan-K2VOL1> there are a lot of differences, most of them resulting in worse flight performance and lower burst altitude
[05:21] <Dan-K2VOL1> oh neat, I never realized the atlas was inspired by SNOX
[05:22] <Dan-K2VOL1> anyway, the silver balloons used in picoatlas were attempts to acheive a superpressure float, which requires a non-elastic balloon
[05:23] <grayhatpython> ok now tell which one we have to choose? single or dual?
[05:26] <Dan-K2VOL1> my advice is to avoid single, avoid dual except for special flights after you're comfortable with single. I've done one flight with two, and it wasn't worth the hassle
[05:26] <Dan-K2VOL1> and done 35 with single
[05:28] <grayhatpython> so i want to choose dual balloon but the diagram of atlas shows it has two balloons aligned in different heights
[05:29] <grayhatpython> i am checking snox but they seem to be single balloon
[05:29] <grayhatpython> can you link me to any good dual balloon project?
[05:30] <Dan-K2VOL1> why do you want to do a dual balloon?
[05:32] <Dan-K2VOL1> I don't know any offhand that are accessible, there was UX-3 by UTARC, but I don't think the info is online anymore. if you want to do dual balloon, my advice would be to make the strings the same length
[05:33] <Dan-K2VOL1> otherwise the rope will rub against the lower balloon and pop it prematurely
[05:34] <grayhatpython> but the atlas diagram shows they are in different height right? i mean the rope itself.
[05:35] <Dan-K2VOL1> if it was, it was poorly chosen, in my opinion
[05:37] <aetaric> Dan-K2VOL1: what time will you be at the space?
[05:41] <Dan-K2VOL1> I'm here now, and will be here tomorrow from 10 am till 5, then 8 till late!
[05:41] <aetaric> ok, i'll be heading up there around 12

[08:06] <earthshine> Morning
[08:06] <Dan-K2VOL> delorme doesn't seem to release the iridium 9602 modems after the contract expires
[08:06] <natrium42> so you can't reuse it?
[08:06] <Dan-K2VOL> not with another provider
[08:07] <natrium42> does it have a sim card?
[08:07] <Dan-K2VOL> I haven't checked to see if you can before you activate it with delorme
[08:07] <Dan-K2VOL> no
[08:07] <Dan-K2VOL> just an IMEI
[08:07] <Dan-K2VOL> number
[08:07] <natrium42> maybe it's soldered in?
[08:07] <natrium42> i had same problem with my iridium phone
[08:07] <natrium42> contract expired
[08:07] <natrium42> then i wanted to renew it and they told me to get a new SIM
[08:08] <Dan-K2VOL> Delorme is allowed to deactivate it with iridium, they just aren't doing so automatically.
[08:08] <Dan-K2VOL> I called them today and asked them to. They said they'd call me back
[08:08] <natrium42> ah, well let me know how it goes!
[08:09] <natrium42> i might do a latex launch in a few weeks
[08:09] <jcoxon> natrium42, floater!
[08:09] <natrium42> for promotional purposes
[08:09] <jcoxon> not a floater!
[08:09] <Dan-K2VOL> oh? promotional?
[08:10] <natrium42> no time for that, have tight deadlines for startup thingy
[08:10] <Dan-K2VOL> heh there's some trans-atlantic competition these days
[08:10] <natrium42> but we could use it to test camera stabilization

[08:22] <Dan-K2VOL> on the digi-key part
[08:22] <eroomde> confusingly
[08:23] <eroomde> i do want to move to the states
[08:23] <Dan-K2VOL> extremely. I resoldered that about 5 times
[08:23] <eroomde> digikey is very good
[08:23] <eroomde> and ebay has a lot more old test equipment on it
[08:23] <Dan-K2VOL> hmm that's interesting, I hadn't thought about not having digi-key if I move to europe
[08:23] <eroomde> well actually it's ok
[08:24] <eroomde> you have farnell, RS, Mouser etc
[08:24] <Dan-K2VOL> oh good
[08:24] <eroomde> and actually they're all very good
[08:24] <UpuWork> if a tad expensive
[08:24] <eroomde> yes indeed
[08:24] <eroomde> but similar to digikey really
[08:24] <UpuWork> We have ChinaRF too :)
[08:24] <UpuWork> as does anyone in the world tbh
[08:24] <cuddykid> :D
[08:24] <eroomde> it's the price you pay for the convenience of single digit quantities
[08:24] <Dan-K2VOL> heh
[08:24] <daveake> Digikey ship here and have UK prices
[08:25] <UpuWork> yeah watch this space...

[08:25] <daveake> Plus there's UpuShop
[08:25] <UpuWork> GPS modules should be here today eroomde
[08:25] <eroomde> a day designing, one big RS order list which has everything - components, case, wiring, etc, build it the next day and write some documentation
[08:25] <eroomde> ah super!
[08:25] <eroomde> i need to get the pcb fnished
[08:25] <daveake> what's that last bit?
[08:25] <eroomde> yesterday was a bit of a fail
[08:25] <daveake> docu-something :p
[08:25] <eroomde> daveake: yeah annoying huh
[08:26] <eroomde> have learnt that they quite like it
[08:26] <daveake> yep :)
[08:26] <daveake> indeed
[08:26] <eroomde> just a schematic or something
[08:26] <eroomde> never too unreasonable
[08:26] <daveake> good
[08:26] <eroomde> but they have lots of techs at culham who like being able to fix things themselves
[08:26] <eroomde> rather than order the subcontractor back in
[08:26] <eroomde> quite right (tm) really
[08:27] <daveake> yep
[08:28] <Dan-K2VOL> :-) night friends, I'm going to bed, tomorrow the new iridium modem arrives, sat comm controller integration begins!
[08:28] <daveake> One of my German customers is quite good at that, but had a difficult problem that he wasn't solving even with my help. He sent me a video of das blinkenlightun, bless him, and I diagnosed a dodgy PSU from the fact that I could see my board resetting
[08:28] <eroomde> happy fun time
[08:28] <eroomde> cool!
[08:28] <Dan-K2VOL> nice daveake
[08:28] <daveake> That saved a trip

[08:30] <daveake> Though I'm not looking forward to soldering on 1200 of the buggers
[08:30] <daveake> :)
[08:30] <eroomde> yeah what is this for?
[08:30] <eroomde> it sounds masochistic
[08:31] <daveake> Control card for ink dispensers ... think of the kind of thing you might see in any large DIY store for mixing paints to match the colour you want, but bigger. Used in package printing mainly but also for dyehouses and other applications
[08:31] <fsphil> sweet
[08:31] <daveake> So it opens and closes valves, switches pumps on and off, measures weights via scales, etc
[08:32] <daveake> It's kept me off the straights for a while (20 years in business on my own next month)

[08:32] <fsphil> congratulations
[08:33] <daveake> I shall be doing a launch to celebrate, hopefully
[08:33] <eroomde> ah nice
[08:33] <eroomde> congrats
[08:33] <fsphil> I wouldn't even know where to start with running my own business
[08:34] <daveake> Well I was lucky in that my old emplyers (in the same business, unsurprisingly) gave me work at the start - they never replaced me
[08:34] <daveake> As that tailed off other stuff picked up
[08:34] <daveake> You need luck in business.
[08:35] <eroomde> yeah - a good starting project seems to be key
[08:35] <eroomde> and takes a lot of effort to find
[08:36] <daveake> Yep. At the start I'd take on anything, just to keep the money coming in but also, more importantly, to start building up more contacts
[08:37] <daveake> It's a video, and you might not want to watch much of it, but this machine has some of my software in it, and also these cards I'm building - http://www.microblendtechnologies.com/mb/index.php?c=118
[08:39] <daveake> The software you see on that one isn't mine - my bit just does the actual dispensing not the UI
[08:39] <eroomde> the fun bit
[08:40] <daveake> Indeed. For my other stuff I do both, but in this case the manufacturer had there own - they just couldn't do the weight-based (gravimetric) dispensing. So rather than learn they got me to do it.

[10:14] <CovBalloon> the blue balloon
[10:15] <daveake> loves to get blown in the wind
[10:17] <CovBalloon> has anyone used two balloons for a more rapid assent and higher altitude/
[10:17] <fsphil> afaik it won't get any higher
[10:18] chris_99 (~chris_99@unaffiliated/chris-99/x-3062929) joined #highaltitude.
[10:18] <fsphil> not much anyway
[10:18] <fsphil> unless you've a really heavy payload
[10:18] <fsphil> also, they get really really big - you'd have to separate them
[10:20] <Randomskk> CovBalloon: the only reason we've used multiple balloons is heavy payloads
[10:20] <Randomskk> though you could definitely use them to get very rapid ascents
[10:21] <fsphil> yea
[10:21] <Randomskk> expensive though
[10:21] <eroomde> i have tried both
[10:21] <eroomde> i.e. for speed and scent
[10:21] <eroomde> 1) you don't have to separate - they will do it anyway
[10:22] <eroomde> 2) the configuration we've tried 2 or 3 times now was as follows:
[10:22] <fsphil> ah, so having them in contact is harmless?
[10:22] <eroomde> 1 x small balloon, highly filled, lots of lift and fairly low burst
[10:23] <eroomde> 1 x much bigger balloon, which on its own would give a very slow (eg 2m/s) ascent rate to the payload
[10:23] <eroomde> you attach them, and the small viscious one does most of the hauling up to say 20-25km altitude
[10:23] <eroomde> at which point you release it - you're above the jet stream and other crap by this point
[10:23] <eroomde> and then you continue ascending slowly to a high altitude under the big balloon
[10:24] <fsphil> two stage balloon launch. neat
[10:24] <eroomde> indeed
[10:24] <eroomde> the small one is sort of analogour to a tugboat getting a big ship out of harbour
[10:25] <eroomde> it gets you out of the zone of atmospheric crappiness, out into the clear and stiller air above the jet stream
[10:26] <CovBalloon> is anyone up for a balloon launch in the near future with multiple payloads?
[10:27] <CovBalloon> and what would be the downside to doing that/
[10:27] <Darkside> you mean you want to put your payload on someone elses launch
[10:27] <Darkside> :P
[10:27] <eroomde> folks are often quite amenable to the idea yep
[10:27] <eroomde> obviously depends on the payload :)
[10:27] <Darkside> we almost always fly multiple payloads
[10:27] <UpuWork> I launched 2 at once
[10:27] <Darkside> kind of a waste of a launch otherwise
[10:28] <CovBalloon> I am happy to organise it but I just think if we collaborated we could do more launches
[10:28] <UpuWork> unless people are going for records it makes sense
[10:28] <daveake> CovBalloon what sort of weight?
[10:28] <CovBalloon> to be determined right now but would imagine less that 500g
[10:29] <CovBalloon> it depends onhow many tracking devices etc we want to carry
[10:30] <eroomde> two is almost always better than 1
[10:30] <eroomde> but 3 being better than 2 is quite questionable
[10:30] <daveake> ok. I've applied for 24th March, and some backup dates. I've asked for permission to have 2 launches on the same day. I've not decided yet exactly what to fly but one will be a small/light payload, for altitude or float, but the other will be a photographic payload. You could go on that second one.
[10:32] <daveake> It'll be a 1600g hwoyee and my payload will probably be 250g, so plenty of capacity left
[10:32] mikewintermute (~mikewinte@188-223-213-21.zone14.bethere.co.uk) joined #highaltitude.
[10:33] <daveake> We'd need to sort out frequencies, but my small payload has an rfm22b so that can be set in software. Currently the 250g payload is at 434.650 but that could be changed.
[10:36] <CovBalloon> OK, very interested Dave, can we chat onthe phone
[10:36] <daveake> sure
[10:37] <MLow> morning some of you
[10:40] <Darkside> 9pm here :-)
[10:41] <fsphil> lol
[10:41] <MLow> darkside you hear the good news?

[10:45] <Darkside> frick
[10:45] <Darkside> dlat and dlong do not help unless you know the absolute latitude
[10:45] <eroomde> correctos
[10:46] <Darkside> ok...
[10:46] <eroomde> you need the wikipedia page, my son
[10:46] <Darkside> i need to write out all the arrays in my code
[10:46] <Darkside> so i get this right
[10:46] <eroomde> or look at the predictor source
[10:46] <Darkside> eroomde: heh
[10:46] <Darkside> eroomde: i'm trying to do a path integral over an ionospheric raytrace
[10:47] <Darkside> i have the latitude, longitude and altitude coordinate for every point in the ray
[10:47] <Darkside> i'm very certainly going to have to account for a spherical earch

[10:48] <Darkside> lol
[10:48] <MLow> hahaha
[10:48] <Darkside> hmm
[10:48] <MLow> im not much for names
[10:48] <Darkside> i wonder if i'd do best to convert to a polar coordinate system
[10:48] <Darkside> and work in that space
[10:48] <Darkside> oh wait
[10:48] <eroomde> heh, work in space.
[10:48] <eroomde> lol.
[10:48] <Darkside> i already am in a polar coordinate system
[10:48] <Darkside> derp
[10:49] <Darkside> spherical*
[10:49] <eroomde> something about cartesian bears
[10:50] <Darkside> latitude is theta, longitude is phi, altitude is r + earth radius
[10:50] <Darkside> r - earth radius
[10:50] <Darkside> but the earth isnt spherica
[10:50] <Darkside> GAAAAARGH
[10:51] <eroomde> go forth and multiply
[10:51] <Darkside> yeah i'm not implementing that
[10:51] <Darkside> ff
[10:52] <eroomde> nah it's not too bad
[10:52] <eroomde> it has a datam surface which you can use
[10:52] <eroomde> which is just an oblate spheroid
[10:52] <eroomde> you can ignore the rest
[10:52] <Hibby> o/
[10:52] <Darkside> tbh all i want is the straight distance between 2 lat/long/alt coordinates
[10:52] <Darkside> well, the absolute distance between them
[10:52] <eroomde> it'll give you goo enough estimates of actual radius from the cnetre of the earth if you use that and then add height above sea level
[10:52] <Darkside> that is ALL i need
[10:53] <eroomde> ok
[10:53] <eroomde> well i'd just convert to cartesian
[10:53] <eroomde> and be done with it
[10:53] <Darkside> but i cant use the standard conversions
[10:53] <Darkside> hmm
[10:53] <Darkside> no, i dont think it will be good enough over such a small area
[10:53] <Darkside> ack. brain melt
[10:53] <eroomde> it's 9pm
[10:54] <eroomde> go and have a whisky
[10:54] <eroomde> and smoke a pipe
[10:54] <Darkside> the mean distance between each point is about 20km or so
[10:54] <Darkside> heh
[10:55] <eroomde> i've started trying to aquire the taste for whisky
[10:55] <eroomde> always struggled
[10:55] <eroomde> but a good friend is now really into it and has 14 bottles and can give a 10 minute speech about each one
[10:55] <eroomde> which is entirely lost on me
[10:56] <eroomde> but, i am going to give it a whirl as there must be something in it
[10:56] <eroomde> however, i've noticed i've been having the most wild dreams since i started having one before bed
[10:56] <gonzo_> does the 10 mins become 20mins of sluring by bottle 11?
[10:57] <number10> it has a tendancy to do that
[10:57] <eroomde> he seems to hold it quite well
[10:57] <eroomde> what throws him is when i give my input
[10:57] <number10> it also seems to make some people aggressive
[10:57] <cuddykid> has anyone had a a really dodgy cyberduck before? In other words - it never uploads anything and connection constantly drops/fails
[10:57] <eroomde> eg 'mmm yes, i imagine this would be really nice with coke'
[10:57] <cuddykid> net2ftp works fine
[10:58] <number10> I think that may have anoyed him
[10:58] <eroomde> but i'm taking it seriously now
[10:58] <eroomde> he recommended a goos starter bottle and i must say i'm getting into it
[10:58] <eroomde> good*
[10:59] <daveake> Always nice after goose
[10:59] <eroomde> that's a good question
[10:59] <eroomde> what foods go with whisky
[10:59] <eroomde> i mean it's not really a with-a-meal drink
[10:59] <eroomde> but still
[10:59] <cuddykid> lol eroomde
[10:59] Action: LazyLeopard was in a green room at an Eastercon a few years back. For some reason, one of the programme items was a whisky tasting. Most programme participants ordered a single drink through the green room. That item's participants ordered about two or three jugs of water each...
[10:59] <number10> well one thing for certain its not much good as a cooking ingredient
[11:00] <LazyLeopard> I think a certain I. A. Banks might have been involved...
[11:00] <daveake> :-). Brandy is good though, in a flambe
[11:00] <eroomde> always fun
[11:00] <eroomde> i made some red wine catch light yuesterday
[11:00] <daveake> Julie usually worries wehen I dosh it in, but the flames have never taken the house down yet
[11:01] <daveake> red wine? Didn't think that wiould be alcoholic enough
[11:01] <number10> must have super heated it in a pressure cooker
[11:02] <cuddykid> daveake: make a flambé when doing your first hydrogen launch :P
[11:02] <eroomde> i was using it to deglaze an incredibly hot skillet that i'd been browing off some meat in
[11:02] <eroomde> so the alcohol almost instantly vapourised out when it hit the metal
[11:02] <eroomde> satisfying flash of flame
[11:03] <daveake> cuddykid ... er, no :p

[11:07] <daveake> optional
[11:07] <fsphil> phew
[11:08] <eroomde> i love onions
[11:08] <number10> I can just visualise it now - daveake has a bit of a static mishap with his first hydrogen balloon, and eroomde is heard to say "it was a satisfying flash of flame"
[11:08] <daveake> lol
[11:09] <cuddykid> hahaa
[11:09] <cuddykid> eroomde: thanks for that
[11:10] <cuddykid> today on the #highaltitude channel, eroomde declared his love for onions haha
[11:10] <Hibby> news at ten!
[11:10] <cuddykid> I have to say, I like onions too :P
[11:11] <MLow> i feel like a weight has been lifted
[11:11] <eroomde> srsly
[11:11] <MLow> srsly
[11:11] <eroomde> i love chopping them
[11:11] <eroomde> and i love recipes where you can just quarter them and throw them in to roast
[11:11] <eroomde> and i love shallots that you can jsut throw in whole
[11:11] <Hibby> I'm not an onion fan - don't like the texture
[11:11] <eroomde> in a big slow cooking pot of red wine and beef
[11:11] <MLow> im about to make a soup this weekend, lots of onion
[11:12] <eroomde> i love caramalised onions that you leave on almost no heat for an hour, prodding occassionally
[11:12] <Hibby> however, potatoes... phwooooar.
[11:12] <eroomde> did you know that onions don't actually taste sour in the wild?
[11:12] <eroomde> it's because sulphur is added to the soil deliberately
[11:12] <eroomde> it's just a consumer expectation thing

[11:14] <cuddykid> I don't suppose anyone on here has made a bike tracker? I might use my new found noob pcb skills and create a teeny one for under the saddle after my loss yesterday
[11:14] <cuddykid> gps, gsm, and chip, could get quite small indeed
[11:14] <CovBalloon> dynamo to power it
[11:14] <cuddykid> yep, or tiny watch style battery
[11:14] <MLow> i was going to go with fart powered but whatever
[11:14] <CovBalloon> wshen was the last time you saw a dynamo on a bike
[11:15] <cuddykid> just have it wake up and get lock when required
[11:15] <cuddykid> very very low power consumption
[11:15] <cuddykid> there are tiny batteries that would power it for a long time
[11:15] <eroomde> you can get much better dynamos for bikes nowadays
[11:15] <cuddykid> also - could have an on/off button to save more
[11:15] <eroomde> that are built into the hubs
[11:15] <eroomde> rather than those nasty wheels that press against the rim

[11:16] <cuddykid> I might have a go at making one, would be an interesting project
[11:17] <CovBalloon> is it in upu's shop yet?
[11:17] <MLow> wouldnt u think tho it would be pretty obvious some valuable electronics are under the seat

[11:59] <Darkside> vk5gr: hey
[11:59] <Darkside> sorry for the delay
[11:59] <vk5gr> hi there!
[11:59] <Darkside> hey
[11:59] <vk5gr> no probs - just wondering if there is any reason still to not put up the horus 21 launch and landing footage? just finished a quick edit and stabilisation of it so it can be referenced int he blogs?
[12:00] <Darkside> i'd put it up
[12:00] <Laurenceb> "We have 2 new 19” TFT Monitors which were ordered and delivered in August 2011. They have your name written on them"
[12:00] <Laurenceb> wtf
[12:00] <vk5gr> (and yes I removed your histerical laughing at the end :-)
[12:00] <Laurenceb> thats got to be an epic spam
[12:00] <Darkside> vk5gr: oh good
[12:00] <vk5gr> no probs - it will be online shortly :-)
[12:01] <Darkside> vk5gr: i'm about to do something dodgy on RSB
[12:01] <Darkside> going to be a LID for a little bit
[12:01] <gonzo_> if it was 'delivered 2009', that could have been from our stores dept
[12:01] <Darkside> since RSB isnt licensed for what i'd like to do
[12:01] <Darkside> which is send OFDM data over it
[12:01] <Darkside> to test codec2 on air
[12:02] <Darkside> its not going to sound very nice
[12:02] <vk5gr> just announce your call in plain FM before and after and no one will care
[12:02] <Darkside> but
[12:02] <Darkside> RSB is licenced for telephony only
[12:02] <vk5gr> back to my earlier comment - for a couple of minutes as an experiment - no one will care
[12:02] <Darkside> screw it
[12:02] <Darkside> ok
[12:03] <Darkside> vk5gr: if you have a handheld, tune it to RSB now
[12:03] <Darkside> we're about to test
[12:03] <vk5gr> not handy im afraid
[12:03] <Darkside> damn
[12:03] <Darkside> ok
[12:05] <Darkside> woot
[12:05] <Darkside> it worked
[12:05] <fsphil> yay
[12:05] <Darkside> shenki has a video recording
[12:05] <vk5gr> RSB's audio was wide enough then
[12:05] <Darkside> yeah
[12:05] <Darkside> its only 2.2KHz wide
[12:05] <vk5gr> good - I knew that Paul had done some tricks with it
[12:05] <Laurenceb> what happened to WB8ELK10?
[12:06] <vk5gr> shenki has a video recording of what?
[12:06] <vk5gr> horus 20?
[12:06] <Darkside> of the test we just did
[12:06] <Darkside> as for horus 20 videos, no damn idea
[12:06] <Darkside> i'm sure they're out there
[12:06] <vk5gr> did you see that we were finally allowed to release the horus 18 flight video as well?
[12:06] <Darkside> i just dont know who has them
[12:06] <Darkside> yep, i saw that
[12:06] <Darkside> good work on it :D
[12:06] <Darkside> who chose the music :P
[12:06] <vk5gr> 24000+ views on YouTube - pretty happy about that
[12:07] <vk5gr> the music was their choice in the end - they had a guy write sxomething to go with the film - a most excellent way of doing it!

[12:11] <vk5gr> thanks - do you want to check the shoirt blurb i wrote here for accuracy: http://vimeo.com/36894457
[12:12] <Darkside> vk5gr: there was also horus 20 on the tuesday
[12:12] <Darkside> are you going to mention that at all?
[12:12] <vk5gr> no - i'll just talk about the flight the video refers to - will leave the full discussion to the blog
[12:13] <Darkside> ok
[12:13] <Darkside> sure
[12:13] <vk5gr> the film is about 10-15 mins away from being ready to watch
[12:13] <Darkside> cool
[12:13] <vk5gr> we really need to get you to hold the camera a little stiller too :-) The stabilisation had a very hard time with this :-)
[12:14] <Darkside> haha
[12:14] <Darkside> well it was hard to do that in a moving car with my phones camera
[12:14] <vk5gr> you need a set of rails, follow focus and a shoulder rig :-)
[12:14] <Darkside> hahaha
[12:14] <vk5gr> is that just phone footage?
[12:15] <vk5gr> which phone?
[12:15] <Darkside> Samsung Galaxy S II
[12:16] <vk5gr> ahhh ok - so thats what the video of the SGII looks like! I am still toying between it and the iPhone4S - cant make up my mind. The Apple does some video app things way better than android at present - but the apps I can get on the SGII for other things make it a tough choice
[12:16] <Darkside> SGSII
[12:16] <Darkside> hands down
[12:16] <vk5gr> may just have to wait for the iPhoine5 and see if it is 1800MHz 4G
[12:16] <Darkside> ot something newer
[12:17] <Darkside> but yeah, the SGSIIs camera is pretty good if you aren't shaking it around a lot
[12:17] <vk5gr> if there was a good android video editing and vimeo interface app, then the SGSII would have won
[12:17] <vk5gr> looks like the SGSII'
[12:17] <vk5gr> s rolling shutter is worst than I have seen with an iPhone though - a bit of a worry
[12:18] <Darkside> i wouldn't edit video on the phone...
[12:18] <Darkside> do that in something better

[13:35] <eroomde> that's true

[14:01] <gonzo_> all smd resistors are thick film aren#t thay?
[14:01] <cuddykid> cheers eroomde
[14:01] <eroomde> so the other types of resistor design are for more specific and niche applications where you might need some specific properly, like a particularly low inductance perhaps
[14:02] <eroomde> which you might need to, say, measure the current (by measuring the voltage drop across the resistor - V=IR - for a high speed switching power supply, where the inductance would otherwise sponge out your high speed signal)
[14:03] <SpeedEvil> gonzo_: no - some are metal film

[14:47] <eroomde> you could strap it to the side of your house fairly innoccuously

[14:49] <eroomde> also a vertical and a purely horizontal yagi might be good
[14:49] <eroomde> with a co-ax relay to switch between them remotely
[14:50] <eroomde> i say this because within about 200-300km a vertical is completely fine for habs, it seems
[14:50] <eroomde> and from 300km away, 30km up, thats arctan(30/300) which is like 5 degrees elevation
[14:50] <eroomde> which isn't much at all
[14:51] <eroomde> so would probably happily fall in the 3db beamwidth of a yagi aimed at the horizon
[14:51] <eroomde> so you would just need az and not el

[15:45] <navrac> upu - can i order now and just wait for delivery till the breakout boards show up or should i wait and place the order once they are in?
[15:45] <UpuWork> entirely your choice navrac I don't have a date but normally boards take 2 weeks
[15:46] <UpuWork> and I've been a week
[15:46] <UpuWork> which ones are you after the ones with the Sarantel ?

[15:47] <cuddykid> oops - http://ava.upuaut.net/store/index.php?route=affiliate/login
[15:47] <navrac> excellent - i think i'll order them now and wait till they arrive - good job - thanks, its much appreciated.
[15:47] <UpuWork> no probs
[15:48] <UpuWork> err ignore that cuddykid
[15:48] <UpuWork> I'll go work out how to turn it off
[15:48] <cuddykid> lol
[15:48] <navrac> i was after a couple of pic ones first as i want to launch as soon as i get back from spain
[15:48] <UpuWork> silly think its disabled ...
[15:48] <UpuWork> thing
[15:50] <cuddykid> still waiting on my APM2
[15:50] <cuddykid> ergh
[15:50] <UpuWork> navrac just be aware I've not tested those yet however if they don't work I'll refund
[15:50] <UpuWork> they should be extremely light as I've put them on 0.8mm PCB too
[15:52] <navrac> excellent - I'm sure they will work - the 0.8mm is appreciated as this pico flight has 2xtx and 2xaerials so I'm pushing it a bit
[15:52] <UpuWork> well the antenna doesn't register on my scales
[15:55] <WillDuckworth> nice work Upu

[15:57] <UpuWork> thanks
[15:57] <WillDuckworth> ready to roll :) going to tweak the payload xml/json whatsit thingy and get some testing going to the tracker
[15:59] <WillDuckworth> Upu... order coming your way ;)
[15:59] <UpuWork> Jolly good thx :)
[16:00] <cuddykid> brilliant WillDuckworth - what GPS are you using? Also - I've now sent off my pcb files to be manufactured for the next flight board :D
[16:00] <cuddykid> I think I get 10 back so you can have one if you want - if they turn out right lol
[16:01] <WillDuckworth> cool - going to try that argent gps unit, then Upu's max6
[16:01] <cuddykid> oh right, I haven't heard anything about the argent - my board is going with the neo-6q
[16:02] <SpeedEvil> http://www.youtube.com/watch?feature=player_embedded&v=-RJCAh7jMFQ - china gets tough on antismoking.
[16:02] <SpeedEvil> (There is minor high altitude content)
[16:03] <nigelvh> I haven't run the argent GPS at altitude yet, but on the ground it links up fast, and seems to be sensitive, so I'm pleased with it.
[16:03] <UpuWork> Hey WillDuckworth did you cancel that order ?
[16:03] <UpuWork> says status cancelled
[16:03] <WillDuckworth> nope - went all the way through - paypal special
[16:03] <UpuWork> ok
[16:04] <WillDuckworth> got confirmation emails from paypal and from hab supplies
[16:04] <WillDuckworth> bugs?
[16:04] <UpuWork> probably
[16:05] <UpuWork> breakout boards not in stock yet I'll get them out to you as soon as they are in

[16:13] <daveake> Says canceled on mine too, put in just now

[16:53] <cuddykid> I've got iOS dev account, not mac os though
[16:53] <nigelvh> Yeah, for now I'm pretty happy with Lion. Also, I'm not sure how I feel about the whole not app store apps won't run without right clicking and choosing to run anyway
[16:53] <nigelvh> I hope they make it so you can "approve" an app so you don't have to do that every time.
[16:55] <cuddykid> it looks like in sys prefs there is an option to allow all apps
[16:55] <nigelvh> That will work. I haven't looked terribly closely at everything. I just read an overview.
[16:57] <fsphil> you have to approve apps?
[16:57] <cuddykid> fsphil: only if you select to approve each one individually
[16:58] <nigelvh> They're putting in a new feature that says apps that aren't from the app store need to be approved before the system will let it run
[16:58] <fsphil> what's the default?
[16:58] <nigelvh> The hope is to reduce malware infections.
[16:58] <fsphil> I like the idea, but not sure I like the direction it's going
[16:58] <fsphil> malware an issue on macs?
[16:59] <nigelvh> Yes, It's going the direction of the iPhone/iPad/iPod, where it's all locked down.
[16:59] <cuddykid> fsphil: http://www.apple.com/macosx/mountain-lion/security.html
[16:59] <nigelvh> I have my iPhone and iPad jailbroken, so I can run what I like, and I'm not sure they'd go all the way on the mac, just because of the various applications and the history involved, but it is certainly leaning that way.
[17:00] <fsphil> don't like that at all
[17:01] <cuddykid> they won't go all the way - if they do, they've lost me and millions of others - they're just trying to make it more "safe/secure" for the average user who doesn't download many other apps and doesn't really have any tech know how

[20:46] <cuddykid> Dan-K2VOL: is the satellite modem a good viable uplink alternative? What was the cost?
[20:46] <Pavix> I think the digi development kit is about $300
[20:46] <cuddykid> oh wow :O
[20:46] <Dan-K2VOL> do not use Orbcomm for balloons
[20:46] <Pavix> But data usage, from what I've heard is sparce
[20:47] <cuddykid> I suppose it's a good idea for long duration ones - if there is a good chance of recovery
[20:47] <Pavix> A friend and I are doing a trans-atlantic solar powered boat, we were going to use that modem to send pics back but then the company rep told us it's best to use small bursts of text, so like gps coords
[20:47] <Dan-K2VOL> I would recommend Iridium currently, for medium to long duration flights, not sure yet about short duration
[20:48] <cuddykid> Pavix: nice
[20:48] <Pavix> afk, work calls :\
[20:48] <Dan-K2VOL> pavix you won't be able to afford sending pics on any service unless you want to spend more than $1000 in data!

[20:48] <Dan-K2VOL> (guessing at that number)
[20:48] <cuddykid> Dan-K2VOL: how much is say a short string of data?
[20:48] <fsphil> or a 16x16 image :)
[20:48] <cuddykid> like UKHAS standard
[20:48] <Dan-K2VOL> yes
[20:49] <fsphil> would binary make more sense there if the number of characters is limited?

[20:49] <fsphil> has anyone seen jonsowman lately? it's like he's been busy with work
[20:49] <Dan-K2VOL> the Iridium 9602 modem will send a max of ~320 bytes from modem, and ~240 bytes TO modem
[20:49] <Dan-K2VOL> yes fsphil
[20:49] <jonsowman> fsphil: it's true :(
[20:49] <Dan-K2VOL> binary is definitely recommended, you pay per byte
[20:50] <Dan-K2VOL> in fact data compression would be better still
[20:50] <cuddykid> Dan-K2VOL: how much per byte?
[20:50] <fsphil> ooch Dan-K2VOL - so it's not even per message like sms?
[20:50] <cuddykid> I guess all that is needed is lat,long,alt
[20:51] <fsphil> lat and lng are fine as 32-bit values
[20:51] <Dan-K2VOL> the iridium providers vary in data costs, but here's a google spreadsheet I made for us to compare a few -

[20:51] <Lunar_Lander> hi jonsowman Dan-K2VOL
[20:51] <jonsowman> hi Lunar_Lander
[20:51] <fsphil> you could get an accurate position and altitude from 11 bytes
[20:52] <Dan-K2VOL> well, this is just one provider, but it shows you a bunch of data options with them, for the cost of one 3 day flight: https://docs.google.com/spreadsheet/ccc?key=0AnfcbUEovLhOdFJib2YxMzhoN3J4S3c3a19ON0M3dkE

[20:56] <fsphil> Pavix, I suppose you could send images over HF radio -- not as reliable but if you've got the power available then essentially free
[20:56] <Dan-K2VOL> heh, well, it's a legitamate risk you're taking, you could have your parachute fall on a motorbike driver's face
[20:56] <cuddykid> not too bad Dan-K2VOL, still quite pricey
[20:57] <Dan-K2VOL> and he could run into a truck on a bridge, which rolls off the bridge, lands on a train track full of people going 200km/h, which piles up and derails into a school full of children
[20:57] <Lunar_Lander> ohhhh!
[20:57] <Dan-K2VOL> ;-) but that's not very likely now, is it
[20:58] <Lunar_Lander> yea
[20:58] <Upu> you missed the part about running over the last remaining unicorn and crashing into the Loch Ness Monster whilst Elvis Prestley lands a UFO on it
[20:59] <Lunar_Lander> xD
[21:01] <daveake> I kinda reduced the odds there with Buzz1, by flying the UFO ...

[21:06] <Dan-K2VOL> haha
[21:06] <daveake> They usually look like that before launch
[21:06] <Lunar_Lander> ROFL we had several payloads painted pink right?
[21:07] <Lunar_Lander> I just had an idea
[21:07] <Lunar_Lander> a payload covered in that jeans stuff
[21:07] <Lunar_Lander> Denim?

[22:25] <cuddykid> guys and gals: is there any 6pin isp programmer you would recommend?
[22:26] <Randomskk> personally I've used USBtinyISP since forever
[22:26] <Upu> I use the Olimex AVR which is about £25 ?
[22:26] <Randomskk> http://www.adafruit.com/products/46
[22:26] <Randomskk> but I dunno if I'd get that now
[22:26] <Randomskk> it works fine and all
[22:26] <cuddykid> thanks :D
[22:26] <jonsowman> i've got the atmel one, that's also fine
[22:27] <Zuph> AVR Dragon is great
[22:27] <Randomskk> I'd be tempted by the AVR dragon, or the AVRISP2 or something
[22:27] <Zuph> Static sensitive, though.
[22:27] <Randomskk> http://uk.farnell.com/atmel/atavrisp2/programmer-avr-mcu-isp/dp/1135517
[22:27] <Randomskk> http://uk.farnell.com/atmel/atavrdragon/emulator-programmer-for-avr/dp/1455088
[22:27] <jonsowman> yeah the avrispMkII is good
[22:27] <Randomskk> yea we lost a dragon due to static once
[22:27] <Zuph> just gotta be careful
[22:27] <jonsowman> or "bad mojo" as was written on its case
[22:28] <Randomskk> :P
[22:28] <Randomskk> but that adafruit one is a fun and easy kit, cheap, and has worked fine
[22:28] <Zuph> I don't use mine in a lab environment or anything, just don't stick your fingers where they don't belong.
[22:28] <Randomskk> added bonus, the adafruit one comes with 2x3 pin and 2x5 pin cables
[22:28] <Upu> yeah Olimex AVR-ISP500 does too
[22:29] <Randomskk> which is really handy - the 2x5pin is larger but a much firmer connection and easier to route, so I've used it on boards in the past
[22:29] <Randomskk> admittedly these days I tend to just use the 2x3 due to board space
[22:29] <cuddykid> I'm tempted to get a cheap one off ebay from china - is that a bad idea?
[22:29] <Upu> no idea where I bought it
[22:29] <Randomskk> meh
[22:29] <Upu> Get a Olimex AVR-ISP500 they are only £25
[22:29] <Randomskk> it'l "probably" work fine
[22:29] <Upu> no idea where I got it though
[22:29] <Randomskk> but like yea, that olimex, or the one I linked is only $22 so even cheaper
[22:30] <Randomskk> sparkfun sell their own as well
[22:30] <Randomskk> which I hear works
[22:30] <Randomskk> the thing about getting a cheap/dodgy one from ebay is that it's suddenly hard to know if your circuit/PCB/AVR is broken or your prorammer is
[22:30] <Upu> this might help too cuddykid : http://ava.upuaut.net/?p=236
[22:30] <Randomskk> when all you get is "initialisation failed, rc=-1" and you're going "uhm... what..."
[22:30] <cuddykid> thanks Upu
[22:31] <jonsowman> oh i love that error
[22:31] <Randomskk> ikr
[22:31] <Randomskk> so helpful

[22:34] <jonsowman> pick whichever you like
[22:36] <nigelvh> I made one using the arduinoISP sketch and a spare 328p I had laying around.
[22:37] <nigelvh> Though that chip is overkill for the application.
[22:37] <jonsowman> i think the adafruit one uses a 2313

[22:37] <Randomskk> indeed
[22:38] <Randomskk> looks like a near-exact copy of the adafruit one :P probably works just fine, go fo rit
[22:38] <Randomskk> oh but no case
[22:38] <Randomskk> I'd maybe consider getting one with a case
[22:38] <Randomskk> like the adafruit one or the atmel one or the olimex one...
[22:39] <jonsowman> that looks very similar to the internals of the adafruit one
[22:39] <daveake> What do you think this looks like? :p http://www.ebay.co.uk/itm/OLIMEX-AVR-ISP500-TINY-PROGRAMMER-ATMEL-STK500-COMPATIBLE-/260938311779?pt=UK_BOI_Electrical_Components_Supplies_ET&hash=item3cc122a863#ht_500wt_1156

[22:55] <fsphil-laptop> vvvvlf
[22:55] <fsphil-laptop> the new 500khz amateur band should be interesting, and totally impossible for me to use
[22:56] <nigelvh> Yes, that does sound intruiging.
[22:56] <nigelvh> Once things are good, I may have to mod one of my rigs to xmit there.
[22:56] <fsphil-laptop> doubtful the 817 can be modded for that
[22:57] <fsphil-laptop> without hardware hacks anyway
[22:57] <nigelvh> I don't know if the 817 has a mars unlock
[22:57] <nigelvh> Most rigs do.
[22:57] <nigelvh> I know my 950 does.
[22:58] <fsphil-laptop> there are jumpers that can be soldered to change settings
[22:58] <fsphil-laptop> but I'm not brave enough to open it :)
[22:58] <nigelvh> Yeah. I'm sure there's one you can solder to unlock the transmit bands.
[22:59] <nigelvh> The better question is to try listening there, and if there and if it's worthwhile, then consider making the mod.
[22:59] <nigelvh> I figure it would make for some good JT65.
[23:02] <fsphil-laptop> yea, the low power favours slow modes
[23:03] <nigelvh> We will have to see what comes of it all. In the meantime, I'm going to try setting up my station for remote operation. I think that's gonna be pretty cool.

[23:10] <jiffe98> anyone know where I can get a bnc whip antenna tuned to US aprs frequency 144.39? Everything I've looked at is typically tuned higher like in the 150+ range and swr at 144 doesn't look that great
[23:10] <nigelvh> Especially since the cat interface stays active on the 950 even with the rig off, so you can remotely turn the rig on and off. That was my big holdup with my old 706 is that I'd have to leave it on all the time.
[23:11] <jiffe98> I'd tune it myself if I could find a bnc base I could stick a steel rod in
[23:11] <nigelvh> Are you looking for something like a 1/4 wave whip, or something more like a handie talking antenna that's shorter?
[23:12] <jiffe98> 1/4 wave is preferable
[23:13] <nigelvh> I assume you know you'll also need the associated ground plane, in which case, why don't you just use a panel mount bnc jack and solder the wires to it?

[23:18] <nigelvh> DISK FAILURES! MY FAVORITE!
[23:19] <MLow-werk> ssd raid ftw
[23:19] <MLow-werk> too bad i am too poor to have one
[23:19] <fsphil-laptop> don't trust ssd for important data
[23:19] <nigelvh> Exactly
[23:19] <fsphil-laptop> not yet
[23:19] <MLow-werk> not yet?
[23:19] <nigelvh> SSD is good for speed, but the lifetime and reliability are much less unless you buy the expensive SLC enterprise class disks.
[23:20] <MLow-werk> are you kidding, the problems will only get worse with time and die shrinking
[23:20] <MLow-werk> a couple 7000 rps disk drives have lasted me 10 years
[23:20] <MLow-werk> just a parity raid
[23:20] <fsphil-laptop> these disks with the error now are about 6 years old
[23:21] <fsphil-laptop> so not too bad
[23:21] <nigelvh> Not bad at all
[23:21] <MLow-werk> just out of warrantee :P
[23:21] <fsphil-laptop> 1 year out :)
[23:21] <nigelvh> I've had much older and much younger disks die.
[23:21] <fsphil-laptop> the disk in my amiga still works (50mb yay!)
[23:21] <nigelvh> Plus, disks are cheap these days. Get some big new ones.
[23:21] <fsphil-laptop> yea
[23:22] <jonsowman> fsphil-laptop: what's wrong with SSDs for important data?
[23:22] <nigelvh> They die.
[23:22] <jonsowman> what, the entire disk?
[23:23] <MLow-werk> yeah pretty much
[23:23] <MLow-werk> the blocks die
[23:23] <MLow-werk> the controller dies
[23:23] <nigelvh> SSD's (at least the consumer class ones) have issues with dying, as well as write wear outs.
[23:23] <fsphil-laptop> jonsowman, I had one die on me
[23:23] <jonsowman> yes but those blocks are then put out of service
[23:23] <MLow-werk> and the data smushes to smaller clusters of blocks which will then die and lose data
[23:23] <SpeedEvil> jonsowman: In principle, yes
[23:23] <jonsowman> the lifetime of newer SSDs in terms of block write count is a lot
[23:23] <nigelvh> Yes, individual blocks can be put out, but as you gain more blocks out, you're more likely to lose stuff. Also, the controller can die.
[23:23] <SpeedEvil> jonsowman: The problem is you don't know the wear leveling algorithm.
[23:24] <nigelvh> The SLC disks are much more reliable
[23:24] <SpeedEvil> jonsowman: And the controller often does not properly signal wear state to the host
[23:24] <nigelvh> The MLC ones are cheap, but die frequently.
[23:24] <SpeedEvil> (Indeed, in the case of SD, it can't)
[23:24] <jonsowman> whilst that's true i've not seen this ever be a real issue
[23:25] <jonsowman> since the number of write cycles is so high
[23:25] <jonsowman> i guess it depends on what you're using the disk for
[23:25] <Laurenceb_> SpeedEvil: i actually read the arm thumb2 documentation, then redesigned the SDR GPS
[23:25] <jonsowman> but in terms of important data i've certainly never known of an SSD to Just Due
[23:25] <jonsowman> *Die
[23:25] <nigelvh> Yes, some people have good results. But compared to standard hard disks, they aren't as reliable.
[23:25] <SpeedEvil> The number of write cycles can be misleading.
[23:25] <Laurenceb_> thumb2 is weird, as you can have 32bit instructions
[23:25] <Laurenceb_> e.g. add and shift at once
[23:25] <SpeedEvil> hmm
[23:26] <nigelvh> Not to say I wouldn't recommend an SSD, but don't rely on it. (My IT side coming out, "

[23:26] <jonsowman> Laurenceb_: question for you: i'm writing for an stm32, if i declare a variable as 8 bit, is the compiler clever enough to only use 8 bits of a ram word? and leave the rest free for other 8 bit variables, for instance?
[23:26] <SpeedEvil> Woo!
[23:26] <nigelvh> I use an ssd in my pc, but back it up frequently
[23:27] <Laurenceb_> jonsowman: yes
[23:27] <jonsowman> Laurenceb_: thanks :)
[23:27] <fsphil-laptop> I need a better backup habit
[23:27] <SpeedEvil> Laurenceb: 2.048MHz sampling, I assume?
[23:27] <Laurenceb_> cortex has 1byte addressing
[23:27] <Laurenceb_> older arm didnt allow that
[23:27] <jonsowman> Laurenceb_: ah ok, i didn't know that
[23:27] <Laurenceb_> SpeedEvil: yes
[23:27] <jonsowman> thanks
[23:27] <fsphil-laptop> i wish C had a boolean datatype.
[23:27] <nigelvh> My pc backs up the system to a spare disk, and data is backed up to an external drive.
[23:27] <jonsowman> fsphil-laptop: well it sort of does...
[23:28] <SpeedEvil> Laurenceb: I forget - what's F's max clock - 130M?
[23:28] <nigelvh> My mac runs mirrored raid, and then backs up to an external disk.
[23:28] <Laurenceb_> 4.bah Mhz sampling allows 9.8Mhz cpu/channel
[23:28] <Laurenceb_> SpeedEvil: 168Mhz
[23:28] <Laurenceb_> so 16 channels is borderline feasible with 4Msps sampling
[23:28] <SpeedEvil> That's quite a lot of channels
[23:28] <Laurenceb_> yeah, and 4msps is pretty decent
[23:29] <SpeedEvil> Does 4 actually buy you much?
[23:29] <Laurenceb_> yes
[23:29] <SpeedEvil> Jam?
[23:29] <Laurenceb_> it avoids the DLL dithering causing performance hits
[23:29] <SpeedEvil> hmm
[23:29] <Laurenceb_> at 2msps the DLL dithers and misses bit edges
[23:29] <Laurenceb_> so you lose SNR
[23:30] <Laurenceb_> having said that - all the kit SSTL sell uses 1bit 2Msps gps
[23:30] <SpeedEvil> Why does the DLL dither?
[23:30] <SpeedEvil> Is it inherent?
[23:30] <Laurenceb_> because it can never align very well

[23:31] <MLow-werk> nigelvh: you around?

[23:31] <nigelvh> MLow-werk: Yeah
[23:31] <MLow-werk> hows things
[23:32] <nigelvh> Good. Just working and playing with my HF rig recently. Waiting to get my MX145's in so I can try those with packet, see if the tones come out better.
[23:32] <MLow-werk> ah
[23:32] <SpeedEvil> Laurenceb: can't you realign the correlation code on the fly?
[23:32] <MLow-werk> do let me know, even though they are not in stock i might get one when it does
[23:32] <SpeedEvil> Laurenceb: So you're trying to correlate against a 45 degree shiftes version?
[23:32] <Laurenceb_> you can only align any code to the nearest sample
[23:33] <Laurenceb_> so faster sampling allows better alignment
[23:33] <SpeedEvil> MLow-werk: What sort of retail?
[23:33] <nigelvh> MLow-werk: I certainly will. I'll also make sure to put something up on my blog.
[23:33] <Laurenceb_> anyway, zzz
[23:33] <MLow-werk> ?
[23:33] <Laurenceb_> cya
[23:33] <SpeedEvil> Laurenceb: congrats anway!
[23:33] <MLow-werk> coolio will check the blog out
[23:33] <SpeedEvil> Laurenceb: Sounds awesome.
[23:33] <Laurenceb_> heh i only worked out some asm on paper :P
[23:33] <MLow-werk> SpeedEvil: rpc electronics and argent data
[23:33] <Laurenceb_> but yeah i will have to try this on F4 discovery, benchmarking at least
[23:33] <SpeedEvil> Laurenceb: Well - paper is how it starts :)
[23:33] <Laurenceb_> cya

[23:39] <Lunar_Lander> jonsowman: how are you?
[23:40] <jonsowman> good thanks Lunar_Lander, yourself?
[23:40] <Lunar_Lander> me too, thanks
[23:40] <Lunar_Lander> how is Apex III coming along?
[23:40] <jonsowman> oh quite well i think, priyesh and danielsaul are the people to ask
[23:40] <Lunar_Lander> ah
[23:40] <Lunar_Lander> and will there be Apex IV?
[23:40] <Lunar_Lander> :)
[23:40] <jonsowman> i should hope so
[23:41] <Lunar_Lander> yay
[23:41] <jonsowman> apex iii launch is next weekend in fact
[23:41] <jonsowman> given weather etc
[23:41] <Lunar_Lander> awesome!
[23:41] <Lunar_Lander> let's do Apex III with three flights
[23:41] <Lunar_Lander> then we had one Apex I and two Apex II
[23:41] <fsphil-laptop> looking forward for Apex-X
[23:41] <Lunar_Lander> xD
[23:41] <jonsowman> lol
[23:41] <priyesh> i will be so old when apex X happens
[23:41] <fsphil-laptop> lol
[23:42] <Lunar_Lander> XD
[23:42] <Lunar_Lander> hi priyesh
[23:42] <priyesh> if 1 apex is done every year
[23:42] <priyesh> Lunar_Lander: hello
[23:42] <MLow-werk> o/ priyesh
[23:42] <Lunar_Lander> :)
[23:42] <Lunar_Lander> priyesh: so Apex III is nearing completion?
[23:42] <priyesh> then apex X will take place in 2019
[23:42] <Lunar_Lander> xD
[23:43] <priyesh> Lunar_Lander: yeah! have a look at the pictures on the website
[23:43] <priyesh> :D
[23:43] <Lunar_Lander> can you give me the URL please?
[23:43] <priyesh> gallery.apexhab.org
[23:44] <jonsowman> priyesh: timeout
[23:44] <priyesh> the pupils making apex X are only 10 years old atm
[23:44] <priyesh> lol
[23:44] <priyesh> jonsowman: :S - i'll look into it
[23:44] <MLow-werk> url no work
[23:44] <Lunar_Lander> doesn't load for some reason
[23:44] <Lunar_Lander> yea
[23:44] <MLow-werk> wah
[23:45] <MLow-werk> mlowrie.com/blog random plug, going to post pics on my next entry with the hx1 tribulations
[23:45] <Lunar_Lander> priyesh: why doesn't it work?
[23:45] <MLow-werk> there it's loading kinda
[23:45] <priyesh> Lunar_Lander: not sure.. let me look into it
[23:45] <Darkside> fffffffff my bank decided to send me a paypass card
[23:46] <Lunar_Lander> yay now priyesh
[23:46] <Darkside> I dont want a fucking pwnpass card
[23:46] <Darkside> grrg
[23:46] <priyesh> working now
[23:46] <Lunar_Lander> yes
[23:46] <Lunar_Lander> priyesh: may I have some of the promo balloons?
[23:46] <priyesh> if you come meet us at the competition, sure!
[23:46] <priyesh> :P
[23:46] <priyesh> not sure how much postage will cost
[23:47] <Lunar_Lander> :) well daveake sent me a letter, had 68p on it

[23:47] <MLow-werk> whats under the sticker on the "core" picture
[23:47] <danielsaul> My apex balloons. No one having my balloons. All mine.
[23:47] <priyesh> haha
[23:47] <MLow-werk> and is that connector sma?
[23:48] <danielsaul> MLow-werk: Thats the GPS
[23:48] <Lunar_Lander> xD
[23:48] <priyesh> MLow-werk: that's the GPS
[23:48] <priyesh> and yes that's SMA
[23:48] <MLow-werk> im curious how to mount my gps on the pcb
[23:48] <MLow-werk> it's a module but only has a plug
[23:48] <MLow-werk> i guess ill just use double sided tape lol
[23:49] Elwell (~elwell@freenode/staff/elwell) left irc: Remote host closed the connection
[23:51] <Lunar_Lander> cool, priyesh you use a transceiver instead of a normal transmitter?
[23:51] <priyesh> yeah
[23:51] <priyesh> we're planning on uplink
[23:51] <priyesh> all the hardware is there
[23:52] Elwell (~elwell@freenode/staff/elwell) joined #highaltitude.
[23:52] <Lunar_Lander> ah
[23:52] <Lunar_Lander> what does the light module do?
[23:52] <priyesh> just need to write the software for it when we want to use it
[23:52] <Lunar_Lander> yea
[23:52] <priyesh> it measures brightness iirc
[23:52] <Lunar_Lander> oh ok
[23:52] <Lunar_Lander> is the radiation board completed already?
[23:52] fergusnoble (esdentem@repl.esden.net) joined #highaltitude.
[23:52] <priyesh> Lunar_Lander: it's soldered, not sure if it's been tested yet
[23:53] <Lunar_Lander> ah
[23:53] <Lunar_Lander> what photodiode did you put on it?
[23:53] <priyesh> i'll have to look that up for you - one moment
[23:53] <Lunar_Lander> thanks
[23:54] <priyesh> http://www.fairchildsemi.com/ds/QS/QSE773.pdf
[23:54] <Lunar_Lander> ah, thanks
[23:55] <danielsaul> Lunar_Lander: light board is RGB light brightness, so seperate values for red, blue, green and all (same as ApexII)
[23:55] <MLow-werk> i need to hurry up and order my parts and do a pcb
[23:56] <MLow-werk> just being lazy
[23:56] <Lunar_Lander> ah thanks danielsaul
[23:56] fergusnoble (esdentem@repl.esden.net) left irc: Client Quit
[23:56] <Lunar_Lander> does it also output in hex like last time?
[23:56] <MLow-werk> working doubles, sleeping, repeat
[23:57] <priyesh> we havne't decided on the output yet
[23:57] <priyesh> the modules still need a bit of work
[23:57] <priyesh> but the core is pretty much done
[23:57] <priyesh> took it on a test run today
[23:57] <danielsaul> we've hardly decided on anything yet... and we're giving ourselves a week til launch... argh
[23:57] <MLow-werk> is that core hand soldered?
[23:57] <priyesh> MLow-werk: reflowed with a hot air station
[23:57] <MLow-werk> damn you
[23:57] <Lunar_Lander> did it work priyesh?
[23:57] <priyesh> Lunar_Lander: yes :)
[23:57] <MLow-werk> i want to get a skillet and do hot plate reflow :P
[23:58] <danielsaul> (hot air station which I have recently destroyed...)
[23:58] <Lunar_Lander> yay priyesh
[23:58] <MLow-werk> need paste tho
[23:58] <Lunar_Lander> ohh what did you do danielsaul?
[23:58] fergusnoble (esdentem@repl.esden.net) joined #highaltitude.
[23:58] <danielsaul> Blew up the transformer in it
[23:58] <danielsaul> by plugging in the wrong soldering iron to the soldering iron plug on it...
[23:58] <MLow-werk> hard to find good source of paste seeing as they want to ship it refridgerated
[23:58] <danielsaul> Ooopsy
[23:58] <priyesh> MLow-werk: it'll be fine if it's not refridgerated for a while tbh
[23:59] <Lunar_Lander> ohh
[23:59] <MLow-werk> yeah i know
[23:59] <priyesh> although it's a good reason to get a minifridge in our lab :P
[23:59] <MLow-werk> but they refuse to ship it without it
[23:59] <danielsaul> MLow-werk: Ask a company for a syringe as a free sample
[23:59] <Lunar_Lander> priyesh: what functions will it have? we got GPS of course, uplink, RGB light, radiation
[23:59] <Lunar_Lander> what else?
[23:59] <priyesh> cutdown
[23:59] <priyesh> siren
[23:59] <priyesh> gas
[23:59] <priyesh> humidity
