[10:36] <dannyg> Hi, I was planning on using this GPS (http://ava.upuaut.net/store/index.php?route=product/product&product_id=51)
[10:37] <Upu> I would
[10:37] <dannyg> it says it isn't suitable for Arudino though
[10:37] <Upu> no its not
[10:37] <Upu> not a 5V one anyway
[10:37] <dannyg> But it doesn't state why not
[10:37] <Upu> you could use it with a level convertor
[10:37] <Upu> because it runs at 3.3V
[10:37] <dannyg> my arduino uno has a 3.3 supply
[10:37] <Upu> and most of the Arduinos run at 5V
[10:37] <dannyg> is that the only reason
[10:37] <Upu> yes but its logic is 5V
[10:37] <Upu> so could damage it
[10:38] <dannyg> ahhhh ok
[10:38] <Upu> as long as you put a level convertor on the 3.3V supply is probably ok these days (though we never recommended it as on the older boards it was limited to 50mA)
[10:38] <Upu> newer Uno's its more than that
[10:39] <jokke_> well it's perfectly fine to use with arduino with about £1.50 logic level converter ;)
[10:39] <Upu> yep
[10:40] <jokke_> but yeah as Upu said, might be smart to put your own 3v3 power rails for that and not trusting the arduino supplied one
[10:40] <Upu> on the new Uno's it actually comes from a regulator so should be ok
[10:40] <Upu> the older ones got it from the FTDI chip
[10:41] number10 (d42c14ce@gateway/web/freenode/ip.212.44.20.206) left irc: Quit: Page closed
[10:41] <dannyg> I have tested the gps with the 5v logic. Would it be ok to use for a flight or have I just been really lucky so far
[10:44] <Upu> well it could damage the gps module
[10:44] <Upu> absolute maximum is 3.6V
[10:44] <Upu> right afk
[10:45] <dannyg> I was going to launch this weekend. Might not have time to get a level converter :S
[10:46] <edmoore> don't launch then
[10:46] <edmoore> nice and simple
[10:47] <dannyg> also, would I have already damaged it without knowing? or would it stop working completely
[10:47] <edmoore> possibly
[10:48] <edmoore> you have damaged it without knowing
[10:48] <edmoore> you might have been dumping lots of current through an io protection diode, which would be a bad thing
[10:49] <dannyg> If it obtains a lock it should be fine though, right?
[10:50] <edmoore> no
[10:50] <edmoore> if you want someone on this channel to say it's fine for you to use your 3.3V gps at 5V, then you're wasting your time and everyone else's
[10:50] <edmoore> you won't get that here
[10:51] <dannyg> i just want to know if i need to buy a new one if it gets a lock when I put a level convert on it
[10:51] <dannyg> converter
[10:51] <edmoore> oh *if* you get a level converter
[10:51] <edmoore> you might be ok then still
[10:52] <edmoore> so the issue with driving the io pins at 5V is that you might cause the protection diodes to overheat as they dissipate too much current
[10:52] <edmoore> you might get away with this for a few ms here and there but in general it's A Bad Thing
[10:52] <edmoore> from life-limited to life-ending for the chip
[10:55] <dannyg> I can just a level converter for $5 from the shops in the morning. So I wouldn't risk my GPS
[10:56] <dannyg> I was just scared I'd have already damaged it
[10:56] <edmoore> test it thoroughly before flying
[10:57] <edmoore> before doing a flight you will have gone through a set or two of batteries completely with the assembled payload sitting out in the garden and you receiving it from the house/car or whatever, anyway
[10:57] <edmoore> so if the gps holds up after a few hours of that then that's probably as much as you can easily do to have some confidence it'll fly ok

[11:15] <infaddict> lol think you got the point across edmoore
[11:15] <edmoore> well he was asking questions that didn't inspire much confidence
[11:15] <edmoore> so i hope he makes sure the thing works end-to-end before letting go
[11:19] <Upu> lol
[11:19] <Upu> I predict .. failure
[11:20] <Upu> unless he was just joking
[11:20] <Upu> there is always hope
[11:20] <edmoore> hope comes with accepting that you can't really take shortcuts
[11:20] <edmoore> i hope he realises this
[11:21] <edmoore> have known so many projects fail because people say 'i'm a maker!' and spend ages tweeting about it and not just quietly getting on with testing
[11:21] <edmoore> and also thinking about how to make a robust design
[11:21] <Upu> all this
[11:22] <Upu> I suspect he'll realise when he gets it working and then gets to the parsing part of the tracker
[11:22] <edmoore> well hence my point about being able to receive it whilse he's testing
[11:23] <edmoore> he at least has a fighting chance if valid strings are appearing in fldigi still 5+ hours after he turned the payload on
[11:23] <mfa298> fun one with that one is he might have burnt out the rx part of the gps, so it's still able to send nmea messages but he won't be able to set flightmode.
[11:23] <Upu> they are quite resiliant
[11:23] <edmoore> good point
[11:30] <infaddict> do we know his flight name?

[12:57] <ibanezmatt13> has there been much talk about having a separate predictor model for long duration pico flights?
[12:58] <ibanezmatt13> or is it unnecessary
[12:58] <Laurenceb> i dunno how you could improve on hysplit
[12:58] <Laurenceb> i guess look at humiditiy/dewpoint
[12:58] <adamgreig> UI :P
[12:58] <Laurenceb> i meant the hysplit integration
[12:58] <Laurenceb> on habitat
[12:59] <adamgreig> hysplit integration's on the mobile tracker, nothing to do with habitat - you can't use it for prediction before launching, say
[12:59] <Laurenceb> ok
[12:59] <Laurenceb> i see
[12:59] <ibanezmatt13> I'm keen to have a look at the physics behind achieving a long stable altitude, so how the sun affects it etc
[12:59] <Laurenceb> it seems to be a solved problem
[12:59] <Laurenceb> but I'm very suprised how well PS-46 has faired
[13:00] <Laurenceb> i guess its a fluke
[13:00] <Laurenceb> seems to have hit cloud today
[13:01] <Laurenceb> but: fly above ~11km, use H2, pre-stress the envelope, remove all Alu from envelope, and aim for 5% free lift
[13:01] <Laurenceb> seems to be the recipe for success
[13:01] <adamgreig> pre-stress?
[13:01] <ibanezmatt13> has anybody written anything that talks about what actually goes on though, like why you need to do all that?
[13:02] <Laurenceb> hmm no
[13:02] <Laurenceb> thatd make a good conference talk
[13:02] <ibanezmatt13> it really would
[13:02] <Laurenceb> adamgreig: inflate to ~3psi and leave it for ~4 hours
[13:02] <Laurenceb> at ~30C
[13:03] <Laurenceb> Leo spent months and hundreds of prototypes perfecting it
[13:03] <ibanezmatt13> Yeah I've been reading through his write-ups
[13:04] <Laurenceb> yeah he never did a full write up detailing the complete procedure
[13:04] <SpeedEvil> Specific film used is likely to affect the results
[13:04] <Laurenceb> he did a ton of ground tests too
[13:04] <Laurenceb> yes
[13:05] <ibanezmatt13> and the envelope (which I'm guessing is the balloon itself) can be made yourself?
[13:05] <Laurenceb> hack blood pressure meters are very useful
[13:05] <Laurenceb> *hacked, with custom firmware
[13:05] <Laurenceb> yes, sealed ~95cm wide film
[13:06] <Laurenceb> it was PE-EVOH-Nylon6-Alu-Protective coating iirc
[13:06] <Laurenceb> Alu stripped using hot conc NaOH
[13:06] <ibanezmatt13> sounds interesting
[13:06] <Laurenceb> then heat sealed at ~165C iirc, with PTFE tools
[13:07] <ibanezmatt13> craag mentioned yesterday that the buoyancy force is roughly constant, but I was a bit short for time. I thought initially you could find the float altitude from when buoyancy = weight
[13:08] <SpeedEvil> Boyancy is constant for elastic balloons
[13:08] <craag> that was with latex
[13:08] <SpeedEvil> Till they reach their non-elastic range shortly before burst
[13:08] <ibanezmatt13> ah, is that because the volume increases to account for the decrease in density or whatever
[13:08] <SpeedEvil> yes
[13:08] <Laurenceb> after stripping the Alu, Leos film was ~22.5µm iirc
[13:09] <Laurenceb> but then after pre-stretch, prob ~18µm
[13:09] <Laurenceb> I'd be interesting in massively pre stretching a qualatex
[13:09] <ibanezmatt13> the aluminium is removed so it doesn't conduct direct heat from the sun to the gas?
[13:09] <Laurenceb> using a hair dryer to heat a cardboard box
[13:09] <SpeedEvil> The amount of mass of hydrogem they enclose is constant, so given a constant composition of atmosphere, temperature, and shape, the mass of external air interacted with is a constant, so the speeed is a constant
[13:09] <Laurenceb> to ~90C, then stretch the envelope inside
[13:10] <Laurenceb> <ibanezmatt13> the Alu is removed as it doesnt hold up at altitude
[13:10] <SpeedEvil> (for an elastic balloon, where the variation in overpressure with altitude can be neglected)
[13:10] <Laurenceb> within a few days you end up with a mess of corroded and flaking alu
[13:10] <ibanezmatt13> ah right
[13:10] <Laurenceb> that heats the envelope massively
[13:10] <Laurenceb> and it pops in many cases
[13:10] <SpeedEvil> I wonder if that's true if you get up to ~20km
[13:11] <SpeedEvil> (but practically, the Al does nothing useful
[13:11] <ibanezmatt13> ok so the heat sealant is used for that then, to try and keep the gas from changing temp too much?
[13:11] <SpeedEvil> Heat sealing is used to melt the film into a balloon
[13:12] <SpeedEvil> that is - to make a flat film into a balloom by joining edges
[13:12] <ibanezmatt13> ah, totally different
[13:13] <SpeedEvil> the 'cardboard box' mentioned above was to gently expand the ballon into a spherical shape at high temperature, so the wrinkles created when it goes from flat to spherical are allowed to expand and remove stress.
[13:14] <SpeedEvil> This does not happen if it's stressed at ~0C or so. It just rips eventually due to the stress concentration
[13:14] <ibanezmatt13> right yeah
[13:14] Lemml (~andreas@p4FEEA8CF.dip0.t-ipconnect.de) left irc: Read error: Connection reset by peer
[13:14] <SpeedEvil> In principle, you can also fix this by using >>>2 segments for yoru balloon
[13:15] <ibanezmatt13> final q I think, do changes in the ambient temp (and so changes in pressure) have a significant effect on the lift of the balloon, compared to the effect of say icing or direct sunlight?
[13:20] <Laurenceb> ambient doesnt no
[13:21] <Laurenceb> ambient changes the thickness

[16:54] <NormanOK> Hello everyone! I have a couple of questions and hope to get some help from the experts here. I am planning to use CW as the transmission mode of my payload. Is that a bad idea? If not, how do I choose CW in the transmission mode in the radio information page on habitat?
[16:55] <adamgreig> it's a bad idea
[16:55] <adamgreig> which is why it's not a ready option really
[16:55] <adamgreig> computers are very bad at decoding CW in general
[16:55] <NormanOK> :) that's what I was thinking.
[16:55] <adamgreig> and the symbols we use aren't in normal morse
[16:55] <adamgreig> like *
[16:55] <adamgreig> mostly people use RTTY with 7 bit ASCII

[16:56] <NormanOK> sorry for my ignorance but FSK and RTTY are the same thing, right?
[16:57] <adamgreig> basically yea
[16:57] <adamgreig> FSK is more general
[16:57] <SpeedEvil> NormanOK: Where ar eyou?
[16:57] <adamgreig> RTTY is a type of FSK
[16:57] <NormanOK> the radio module I will be using actually does FSK, etc.
[16:57] <adamgreig> might be ok - but many radio modules only do FSK with very wide shifts
[16:57] <NormanOK> I am in Oklahoma, US.
[16:57] <adamgreig> like, tens or hundreds of kHz between tones
[16:57] <adamgreig> typically for amateur reception we require less than 1kHz between tones

[17:00] <adamgreig> ublox are onto 8 by now

[17:03] <NormanOK> I would like to eventually put the components together on my custom pcb. I am learning to use eagle now. But I've never launched a balloon yet. So I thought I would do a couple of launches with modules that are already available in the market. Those were the cheapest ones.
[17:03] <adamgreig> sounds fair!
[17:03] <adamgreig> I recommend KiCAD instead of Eagle
[17:03] <adamgreig> but yes, good plan

[17:08] <NormanOK> the slowest setting with the RF22 library seems to be FSK_Rb2Fd5. Is this what I should be using?
[17:10] <NormanOK> actually it seems there are other ones, I guess this one is the slowest: FSK_Rb_512Fd2_5
[17:10] <adamgreig> at a total guess that's 512 bits per second and 2.5kHz deviation, which would not be appropriate
[17:11] <adamgreig> mostly for balloons people here use 50 or 300 baud and 300 or 450Hz deviation
[17:11] <adamgreig> but I don't actually know what FSK_Rb_512Fd2_5 means, so..
[17:11] <NormanOK> ok I see, I was going to ask about what those numbers are. :)
[17:13] <NormanOK> if I use any of the available modes, I guess nobody will be able to decode them.
[17:14] <adamgreig> it's possible
[17:14] <adamgreig> I've not used the RF22 library, so it's hard to say
[17:14] <adamgreig> you might find you can override it to set your own shift and rate

[17:15] <amell> Has anyone bought rocketman/spherachute parachutes before?
[17:16] <NormanOK> SA6BSS: cool, thank you very much. Mine looks like a mess, with all the soldering and pretty tick wires I used.
[17:16] <amell> Need to land 3.5kg safely and having trouble working out what size I need
[17:16] <adamgreig> what's in your 3.5kg?
[17:16] <adamgreig> reasonably big chute for that
[17:16] <adamgreig> but you wanna do actual maths at this level, mess it up and someone gets hurt
[17:17] <amell> A car battery or two. Nah, it's actually for a rocket but same principle applies
[17:17] <adamgreig> you're talking a couple metres diameter
[17:17] <amell> I worked out an 8 foot rocketman chute gives me 4.3m/s landing
[17:17] <adamgreig> sounds about right
[17:18] <amell> But is that slow enough given that where it will be landing will have people looking up
[17:18] <adamgreig> if they're looking up, they should be able to spot it and get out of the way ;)
[17:18] <amell> I'm more concerned about snapping fibreglass fins than damage to people
[17:18] <adamgreig> you might also look at Fruity Chutes
[17:19] <adamgreig> I have a nice 14' from them that's quite good for rockets
[17:19] <amell> Do you think g10 2mm fibreglass landing at 4.3 m/s will be slow enough not to break
[17:19] <adamgreig> it really depends
[17:19] <amell> Fruity chutes is mega expensive
[17:19] <adamgreig> if it lands in a soft field? sure, fine
[17:19] <adamgreig> if it lands on concrete? good luck
[17:20] <adamgreig> where are you launching?
[17:20] <adamgreig> is this for EARS or IRW or something?
[17:20] <amell> I couldn't predict the softness of the field. I was landing this thing on a 50" chute and a 30" drogue and nearly flipped when it was about to land on concrete
[17:20] <amell> Fortunately it missed
[17:21] <amell> So I need a better chute. Yes it's for MRC midland sky
[17:21] <adamgreig> ah nice
[17:21] <adamgreig> i was there last year
[17:21] <amell> Level 2 rocket
[17:21] <amell> Come again. It's going to be good. 5 M class flights planned
[17:21] <adamgreig> seems fairly heavy for a dry level 2
[17:21] <adamgreig> yea I might
[17:21] <amell> It's a solidly built rocket.
[17:22] <adamgreig> going to be at irw in scotland end of august
[17:22] <adamgreig> when's midland sky?
[17:22] <amell> Built with 54 motor tube. Will take L motors no problem
[17:22] <adamgreig> ah, later
[17:22] <amell> Hang on let me check
[17:22] <adamgreig> 12-13 sept
[17:22] <adamgreig> might be able to make it, might be helping a school do a hab launch though
[17:22] <adamgreig> would not surprise me if I'm there to test stuff
[17:23] <amell> 12-13 sept yes

[17:25] <adamgreig> well, I certainly feel more motivated to ensure your parachute is big enough!
[17:25] <amell> Problem is Steve doesn't have anything bigger than 8 foot rocketman chute.
[17:26] <adamgreig> 8' seems like it will be OK for that though. odds are pretty good of a soft landning anyway

[17:29] <adamgreig> so 4m/s is a bit speedy but onto something vaguely soft you'll be fine
[17:29] <amell> 8' rocketman or a 60" irc fruity chute? Which is slower?
[17:29] <adamgreig> I assume you have a drogue too?
[17:29] <amell> I have more drogues than I know what to do with
[17:29] <adamgreig> well assuming at least one of those deploys it'l help too
[17:30] <adamgreig> 8' rocketman probably better. hard to say without testing really, not sure any of their quoted drag coefficients are very.. good
[17:30] <adamgreig> come to the ukhas conference talk about parachutes ;)
[17:31] <amell> Yeah. Rocket chutes do open quite a bit faster though

[17:38] <adamgreig> At this years event we hope to be able to offer higher flights to 8000 feet
[17:38] <theRealSIbot> In real units: 8000 ft = 2438 m
[17:38] <adamgreig> let's just say the 8000ft ceiling would not be appropriate
[17:38] <theRealSIbot> In real units: 8000 ft = 2438 m
[17:38] <amell> Oh that must be new info. Good. I might prep my cirrus dart then.
[17:38] <amell> theRealSIbot: be quiet
[17:39] <adamgreig> the BALLS cap is quite a lot higher
[17:39] <amell> Indeed.
[17:39] <adamgreig> will probably have an M going up at IRW and maybe we'll redo that rocket with something a bit smaller at MRC
[17:40] <amell> I'm sure another M would be welcome
[17:40] <adamgreig> two Ms gets expensive
[17:40] <adamgreig> might put it in as a contingency though
[17:40] <amell> But you need to bring your own blast plate as they are being launched off the grass airstrip
[17:40] <adamgreig> can probably sort something out
[17:41] <amell> There will be two 8mm rail towers
[17:41] <amell> But you will need to talk to Paul in advance if you want to use one
[17:41] <adamgreig> I'm sure

[17:45] <amell> That's new
[17:45] <amell> To me anyway
[17:45] <mattbrejza> press conference in progress
[17:46] <Lunar_Lander> NASA can order new Pu from DoE
[17:46] <amell> Ice?
[17:46] <amell> Lunar_Lander: I thought they only had enough Pu for one more
[17:47] <Lunar_Lander> yes, he just said 17 kg are available, but congress said yes for producing more
[17:47] <amell> Awesome. As long as we don't have any launch accidents
[17:48] <amell> Be a shame if cape canaveral was out of bounds for many years
[17:51] <mattbrejza> they're supposed to be able to survive launch cockups
[17:51] <adamgreig> you'd hope so
[17:52] <dsockwell> impacting a raspberry pi at orbital velocity...
[17:52] <dsockwell> i bet that'd ruin a lot of days

[18:07] <amell> adamgreig: thinking this through what's the deal with using multiple chutes on the string. Can this be calculated as I do have multiple smaller chutes
[18:08] <adamgreig> generally a bad idea
[18:08] <adamgreig> hmm
[18:08] <adamgreig> well, I was just imagining tied at the same point
[18:08] <adamgreig> if they were in a row then I'm not sure
[18:09] <adamgreig> I suspect the aerodynamics do not work out quite as you'd like
[18:11] <amell> Yeah I'm just thinking if I had a chute on the nose end and one on the booster and worked it out so they have similar descent rates then I might get away with smaller chutes
[18:11] <amell> I've seen some people landing rockets horizontally. Not sure how they manage that.

[18:47] <linuxthefish> hi, can i have a methane balloon?
[18:47] <Laurenceb_> i can haz a fart balloon?
[18:49] <DL7AD> linuxthefish: no it doesnt produce any lift
[18:50] <linuxthefish> :(
[18:50] <amell> wouldnt you spend more on beans than helium?
[18:50] <mattbrejza> who said he wanted to produce lift?
[18:50] <mattbrejza> (i thought it did though)
[18:55] <amell> New Horizons will also likely pass the Pioneer probes, but will need many years to do so. It won't overtake Pioneer 11 until ~2082 and will not overtake Pioneer 10 until ~2130. Barring some unforseen gravity assist it will never overtake the Voyagers.
[18:55] <amell> Bit sad really, it will probably outlast the earth.

[19:12] <Lunar_Lander> DL7AD, CH4 is less dense than air
[19:17] <SpeedEvil> About half.
[19:18] <SpeedEvil> It also is way cheaper than hydrogen if you've got a tap in kitchen
[19:18] <SpeedEvil> A pound a kilo of lift
