[10:51] <daveake> Well ... a 24V PSU in a control cabinet died.
[10:52] <daveake> Not sure if that went first and took the over-voltaage protection diode, or vice versa
[10:52] <daveake> Either way, when they replaced the PSU the diode let out all its magic smoke

[11:42] navrac_bed (545c0e05@gateway/web/freenode/ip. joined #highaltitude.
[11:42] <fsphil> how is it sending them?
[11:43] <DrLuke> via radio
[11:43] <DrLuke> :)
[11:48] <fsphil> the images don't look too different from those by a c328, although much better colour
[11:52] <kokey> gfsk
[11:53] <kokey> on 48x.xxx mhz
[11:53] <fsphil> actually their field of view matches the C328-6016IR almost exactly
[11:53] <fsphil> and the IR filter would help the colour
[11:53] <fsphil> I bet that's what it is
[11:53] <kokey> nice quality then from a c328
[11:54] <kokey> I'm having a look at arduino PTP libs, wondering if I could pull images off a canon camera
[11:54] <kokey> I've heard some people can do it on some models only
[11:55] <fsphil> that would be very useful
[11:55] <fsphil> if it can be done on an avr anyway
[11:55] <fsphil> Tim had images being grabbed of a canon using gphoto
[11:55] <kokey> seems like many of the functions are in the ptp library for arduino, except image transfer
[11:56] <kokey> ptp supports transfers of only jpgs, but that's fine I guess
[11:57] <fsphil> tis
[11:59] <kokey> those cheap usb webcams, do they just blast a big image back over usb?
[11:59] <fsphil> usually raw or jpeg
[11:59] <fsphil> some of the fancier ones use h.264
[11:59] <fsphil> but there's usually ways to control it
[12:00] <kokey> so it doesn't store it so you can fetch data a bit at a time?
[12:00] <fsphil> I suspect not
[12:00] <fsphil> but don't really know
[12:00] <kokey> oh well, I'll have a play with it, but I'm sure others would have tried to make better cameras work already
[12:01] <kokey> the PTP stuff seems the most promising really because then you can have a pretty decent camera connected
[12:01] <fsphil> yea the canons can be got quite cheap now
[12:01] <fsphil> and vastly outperform the c328's or linksprites
[12:02] <fsphil> but in my case, if sending images at 320x240 the quality isn't a huge factor :)
[12:03] <kokey> yeah though canons are good at adapting to brightness, and the bigger lenses and ccds are good with low light too

[18:56] <Upu> whats the 381 ?
[18:56] <G7PMO_Kev_Hotel> is the "time" string in the sentance used by anything? And does the format matter? The examles seems to be one set of numbers?
[18:56] <G7PMO_Kev_Hotel> mV's
[18:56] <Upu> 381mV ?
[18:56] <Upu> time is good for the logs
[18:57] <G7PMO_Kev_Hotel> err, actually, good point, mv is 10-3 isnt it :)
[18:58] <G7PMO_Kev_Hotel> it is a new SI unit for volts that doesnt require me to split a number and put a decimal point in :)
[18:58] <Upu> you can correct with filters on the payload document
[19:01] <G7PMO_Kev_Hotel> Good to know, or I can just do s.vinmv = s.vin / 0.155 and print the extra char?
[19:01] <Upu> yeah
[19:01] <Upu> you can just return the full mv like 4500 ?
[19:02] <G7PMO_Kev_Hotel> s.vin and s.vinmv are Ints, but the non-integer constant 1.55 or 0.155 seem to work ok in the code?

[20:01] <G7PMO_Kev_Hotel> Hey Mick, Can't help, sorry, never used that radio, but I hear the Q :)
[20:01] <MickMondo> Cheers
[20:01] <Lunar_Lander_> hi MickMondo
[20:01] <Lunar_Lander_> you used the balloon from India?
[20:02] <MickMondo> Hi ya, yes
[20:02] <Lunar_Lander_> how was its performance?
[20:02] <Lunar_Lander_> in your opinion
[20:02] <MickMondo> 2000 gram
[20:03] <MickMondo> Mmmm, I was speaking to the guy from PAWAN today,,
[20:03] <Lunar_Lander_> and where did you buy it?
[20:03] <MickMondo> Yes, I guess it performed really well,
[20:05] <MickMondo> Not the same as the Hyowee for altitude but more predictable, I did file it quite a bit so I reackon a bit less gas and it would get over 40,000
[20:05] <Upu> evening Mick
[20:05] <MickMondo> soory that should be Fill
[20:05] <MickMondo> god my spelling sorry ha ha
[20:05] <Upu> its ok
[20:05] <eroomde> filing makes the altitude more predicatble too though
[20:05] <eroomde> usually around 0m agl
[20:05] <fsphil> it's ok, you're among good company :)
[20:06] <Upu> yeah good typing and accurate spelling aren't a trademark of this channel
[20:06] <MickMondo> thats good then
[20:06] <eroomde> i dunt know wat yor talkign abowt
[20:06] <Upu> hey stop taking the mick out of my accent
[20:06] <eroomde> i never have ever
[20:06] <eroomde> ever
[20:06] <eroomde> not ever once
[20:07] <Upu> still struggling with the RFM22B Mick ?
[20:07] <MickMondo> Oh, got the Balloon from India, his a really nice bloke to deal with, great service
[20:07] <MickMondo> God yes
[20:08] <MickMondo> I'm ready to hang myself...lol
[20:08] <Upu> I thought all the examples on Hope's site were done for Pic ?
[20:08] <MickMondo> Yeah but nothing what we do though
[20:09] <Upu> can you not convert the AVR libraries ?
[20:10] <MickMondo> Looking a james code it looks quite simple, just an unmodulated frequency witch is shifted up and down
[20:10] <Upu> yep
[20:10] <Lunar_Lander_> MickMondo, where did you buy it?
[20:10] <eroomde> i'm watching 'gordon ramsay's ultimate cookery course'
[20:10] <Lunar_Lander_> ah
[20:10] <Lunar_Lander_> any contact info?
[20:10] <MickMondo> From India, direct from PAWAN
[20:10] <Lunar_Lander_> ah
[20:11] <eroomde> compared to his F-Word videos with the rock music bakground and dubbed over barked commands like POACH and SEASON, it's like he's stoned
[20:11] <MickMondo> sorry did message you back
[20:11] <eroomde> he is just talking at a normal pace
[20:11] <eroomde> but it seems so sloooooow
[20:11] <Darkside> MickMondo: my only suggestion is to go through james's code
[20:11] <Darkside> and do exactly what he does
[20:12] <Darkside> his code is the bare essentials for setting it up
[20:12] <MickMondo> Yeah tried that,
[20:12] <MickMondo> Just a noise out of it would be enough
[20:12] <Upu> habe you tried another RFM22B ?
[20:12] <Upu> have
[20:12] <Darkside> bite the bullet and use an arduino?
[20:12] <Darkside> :P
[20:13] <Upu> in fairness they are a bit shit sometimes
[20:13] <MickMondo> yeah and another picaxe
[20:13] <Upu> yeah ok use an Arduino :)
[20:13] <Lunar_Lander_> MickMondo, ah they have paypal?
[20:13] <Upu> or ask Steve for his code :)
[20:14] <MickMondo> Mmm, dont think Steve would do that..

[20:14] <Darkside> not BASIC
[20:14] <Upu> What are you writing in Mick ?
[20:14] <MickMondo> Lunar, yeah he has paypal but doesnt like using it due to the charges
[20:15] <Upu> I thought it was PIC ?
[20:15] <MickMondo> basic because Im think lol
[20:15] <Upu> I'm think too which is why I use Arduino
[20:15] <MickMondo> all my code is basic
[20:15] <eroomde> i find it easier to get myself in a pickle with basic than c
[20:16] <eroomde> c enforces a little structure on my thinking and code structure and program flow
[20:16] <eroomde> which my thinking often needs
[20:16] <MickMondo> Im Ok with basic, just not everything works as it should like the Ublox, that was a pain in the Ar## too
[20:16] <Lunar_Lander_> ah
[20:17] <MickMondo> Contact him and ask, say Michael Cain said to contact you.. ( thats me by the way not the actor )
[20:18] <Lunar_Lander_> ok :)
[20:18] <eroomde> i bet that gets old
[20:19] <Darkside> MickMondo: i'd consider getting an arduino wiring up the RFM to it (via level conversion) and check it works
[20:19] <MickMondo> I was hoping someone would just list all the Registers I need to config but looks like Im out of luck, I'll keep trying and see

[20:41] <Upu> http://ukhas.org.uk
[20:41] <MickMondo> as long as its nothing to do with a RFM22
[20:41] <Upu> lots of information there
[20:41] <anerDev> what's the best predict software ? this http://habhub.org/predict/ ? work in italy ?
[20:42] <Darkside> anerDev: it will work anywhere, so long as there is wind data available
[20:42] <MickMondo> yes it works in Italy, I checked
[20:42] <DrLuke> even on the moon?
[20:42] <MickMondo> Im off to Italy soon
[20:43] <anerDev> thank you ? But, from what database this app give the information ?
[20:44] <MickMondo> My other half is Italian .. hence Bello Mondo ( Beautiful World ) ish ..
[20:45] <MickMondo> ..?
[20:46] <anerDev> what ?? O.o
[20:46] <DrLuke> I like Pizza

[20:46] <anerDev> yes
[20:47] <MickMondo> not sure what you mean ..
[20:47] <natrium> how is information formed?
[20:47] <Upu> its from NOAA

[20:58] <MickMondo> cheers that should be
[20:58] <anerDev> thank u man ...
[20:58] <anerDev> another question
[20:59] <anerDev> what's the range of this tx http://ava.upuaut.net/store/index.php?route=product/product&filter_name=ntx2&product_id=62 ? it need an ext antenna ?
[20:59] <Upu> yes it does
[20:59] <Upu> and on the ground about 500 meters line of sight
[21:00] <Upu> in the air we've had 750km+ out of it
[21:00] <anerDev> wooooowww
[21:00] <Upu> try a 1/4 wave : http://ava.upuaut.net/files/2010-09-03%2019-26-16_0003.jpg
[21:00] <DrLuke> upu: what crazy ass antenna did you use for that?
[21:00] <anerDev> loool
[21:00] <Upu> Watson Colinear
[21:00] <Upu> the middle one
[21:00] <anerDev> for calculate the antenna
[21:01] <Upu> nothing special
[21:01] <anerDev> the formula is lamda = C/f
[21:01] <anerDev> ???
[21:01] <Upu> look I made a 1/4 wave this evening
[21:01] <Upu> http://ava.upuaut.net/wp-content/uploads/2012/09/2012-09-25-13.58.46.jpg
[21:01] <Upu> 164mm
[21:01] <Upu> http://imgur.com/a/hfMzq check that out
[21:01] <DrLuke> that wire doesn't look very straight
[21:02] <MickMondo> That code is for the QFM-TX by Quasar
[21:02] <Upu> the radials are in the straws
[21:02] <DrLuke> oh, I didn't see the straw in the background
[21:02] <anerDev> ok here we go ...
[21:02] <MickMondo> but looks like he has built one with RFM22, I'll mail him
[21:02] <DrLuke> and I totally dig that ball shape
[21:03] <anerDev> Lamda = 300.000 m/s : 434,075 MHz
[21:03] <anerDev> the result is
[21:03] <anerDev> (just moment)
[21:03] <Upu> 164mm...
[21:04] <DrLuke> just google c/434075000
[21:04] <anerDev> 0.690646681 m
[21:04] <Upu> its a 1/4 wave
[21:04] <DrLuke> wait that didn't work out
[21:04] <Upu> so /4
[21:04] <BrainDamage> anerDev: your c is a bit small
[21:04] <anerDev> but u use lamda/4 ?
[21:04] <anerDev> or /2 ?
[21:05] <BrainDamage> c 3*10^8 m/s in SI
[21:05] <anerDev> yes
[21:05] <MickMondo> Ah nice Upu, you have an antenna anylizer then ..?

[21:06] <MickMondo> your the first person I've seen bend the earth plane up
[21:06] <Upu> these aren't perfect as you are meant to bend the radials back
[21:06] <Upu> oh thats not the radial
[21:06] <MickMondo> my new design is 1.02 swr
[21:06] <Upu> radial sticks down in a straw, thats the feed for the board
[21:07] <MickMondo> Mmm, not the radials then ..?

[21:07] <Upu> straws have radials
[21:07] <Upu> coax sticking out at the bottom is to feed from the board
[21:07] <Upu> (its upside down)
[21:08] <MickMondo> have you bent the radials away from the antenna ..? up

[21:08] <MickMondo> ha ha, yeah got what you ment
[21:08] <anerDev> ok men
[21:09] <DrLuke> actually I've read about how you're supposed to bend them until you get a 50 ohm impedance
[21:09] <Upu> I do try bend them but there isn't much wire in there
[21:09] <anerDev> in the SI this is the mesure
[21:09] <MrScienceMan> i found just the thing for habbing

[21:10] <anerDev> Lamba = C/F = (3*10^8 m/s) / (434,075*10^6) = 0,691124 m
[21:10] <anerDev> is correct ?

[21:10] <Upu> to be totally honest Mick I've never really bothered with much analysis on the antennas as they seem to work , my first two launches only had 2 radials which worked fine
[21:10] <anerDev> for /2 is 345,562 mm and for /4 is 172,78 mm
[21:10] <Upu> however Darkside laid some science down on my ass and now I run 4 radials to ensure optimum radiation pattern
[21:11] <DrLuke> lol
[21:11] <DrLuke> wikipedia says you need a minimum of 3
[21:11] <mattbrejza> its also not exactly 1/4 btw
[21:11] <DrLuke> or else you don't get much of a groundplane
[21:11] <MickMondo> I've got an analyzer now and you'd be amazed how far out these antennas are, thats why I asked you at the conference about tracking one of my payloads and dumping it in the north sea,
[21:12] <Upu> well Icarus only had 2 radials
[21:12] <DrLuke> well, with 2 radials you'll have more of a ground-line
[21:12] <DrLuke> it's some geometric thing
[21:12] <MickMondo> Yeah probably better with two that four
[21:12] <Upu> One day I'm going to design the container to hold the antennas at optimum angle and do it properly

[21:32] <Upu> I'm testing a pico payload yes
[21:32] <DrLuke> it even is foldable
[21:32] <MickMondo> yeah I agree
[21:32] <Upu> 35g probably
[21:33] <Upu> sure the 1600g balloon should be ok lifting it
[21:33] <MickMondo> Mmm, is that the one I see ..?
[21:33] <DrLuke> are you going for a height record? :)
[21:33] <Upu> no
[21:33] <Upu> no one goes for the flight record
[21:33] <MickMondo> lol,
[21:33] <DrLuke> why
[21:33] <MickMondo> I do ha ha
[21:33] <Upu> just tends to be a by product of testing
[21:34] <Upu> well to quote Terry Pratchet going for the flight record is like standing on top of a hill in a thunder storm whilst wearing copper underpants shouting all gods are bastards
[21:34] <MickMondo> The best thing Upu is put the balloon in the washing machine first, and wash it thats the trick ....lol
[21:34] <Upu> oh yeah
[21:34] <DrLuke> lol
[21:34] <Upu> the real thing is more or less lift than last time
[21:35] <Upu> its a decision I've not come too yet
[21:35] <MickMondo> ..?
[21:35] <Upu> how much lift
[21:35] <Upu> neck lift
[21:35] <MickMondo> what was your ascent
[21:35] <DrLuke> shouldn't you get crazy ascend rates with such a light payload?
[21:35] <Upu> no you keep the neck lift down
[21:35] <Upu> well we aimed for 5.5m/s last time
[21:36] <Upu> lower and you risk float which I'm not bothered about really
[21:36] <MickMondo> I'd go for 0.5 M/s it wont go into float honest
[21:36] <Upu> lol
[21:36] <Upu> it won't have enough puff to get high either
[21:36] <DrLuke> :)
[21:36] <MickMondo> 5.5 is good
[21:37] <eroomde> try 4.5. see what happens
[21:37] <Upu> its a real balancing act
[21:37] <eroomde> tbh
[21:37] <eroomde> i sound like a broken record and should do something about it
[21:37] <Upu> I was actually going that way eroomde
[21:37] <MickMondo> it will float thats for sure
[21:37] <eroomde> but we really need to stick an accurate pressure sensor on these flights
[21:37] <Upu> yep it'll float
[21:37] <Upu> I don't want a H2 floating really
[21:38] <MickMondo> No bit dodgy
[21:38] <eroomde> cos it's difficult to know if the balloons are actually getting to a lower pressure
[21:38] <MickMondo> you going helium then
[21:38] <Upu> no H2
[21:38] <eroomde> or if they're all going to the same external pressure but that external pressure happens to be physically higher ASL in meters
[21:38] <eroomde> because of the energy in the atmosphere or whatever
[21:39] <MickMondo> is that with dave
[21:39] <Upu> yes
[21:40] <Upu> alot of it is luck of the draw
[21:40] <MickMondo> I think the reason the ballons are unpredictable is the thickness of the latex, its a bit hit and miss
[21:40] <MickMondo> yeah I know, and washing it
[21:40] <MickMondo> joking
[21:40] <Upu> what was the term Dan Bowen used to describe the point where the balloon stretches past the point where it can return ?
[21:40] <SpeedEvil> absolute pressure measurements in and out of the balloon would be awesome
[21:41] <Upu> sure we could do that
[21:41] <eroomde> the creep point
[21:41] <Upu> thats it thanks
[21:41] <eroomde> so the point beyond which it's elastic
[21:41] <SpeedEvil> elastic limit
[21:41] <eroomde> and will just allow itself to be stretched without fighting back
[21:41] <eroomde> which puts it into positive feedback to ascent and so burst
[21:41] <SpeedEvil> where the pressure inside the balloon stops being a constant figure above external
[21:41] <Upu> thats the point where we need it to be at 44km so when it starts its final climb it can take Micks record :)
[21:42] <MickMondo> I guess that would be the point of pressure drop
[21:42] <MickMondo> NOOOOOOOOOOOOO
[21:42] <Laurenceb_> is there an interesting discussion going on?
[21:42] <SpeedEvil> it's complex
[21:42] <Upu> put a pressure sensor in a kinder egg with a AVR and a battery transmitting data via a zigbee or something to the payload
[21:42] <Laurenceb_> im bored && lazy
[21:42] <SpeedEvil> you need extra gas to go up
[21:43] <Laurenceb_> yeah Dans talk was really good
[21:43] <Laurenceb_> is a video online yet?
[21:43] <SpeedEvil> floaters will have lower terminal altitude, I think
[21:43] <eroomde> i wonder if u can detect creep
[21:43] <Laurenceb_> probably
[21:43] <Upu> he described exactly what we saw with Steve's flight
[21:43] <MickMondo> yes I think so
[21:43] <eroomde> i suspect if u can measure differential pressure across the ballon, you probably can
[21:43] <Laurenceb_> i was looking at designing a 1m diameter superpressure
[21:43] <Laurenceb_> and i keep meaning to try silicone psa
[21:43] <Laurenceb_> but as i said im lazy
[21:44] <Laurenceb_> and cannot be bothered
[21:44] <SpeedEvil> Laurenceb: with or without a little steam engine in the middle on a solar mirror
[21:44] <Laurenceb_> but i have _many_ litres of silicone psa
[21:44] <Laurenceb_> hehehe
[21:44] <Laurenceb_> yeah thats my "big idea"
[21:44] <MickMondo> Cant believe the time, gone so fast tonight
[21:44] <Upu> welcome to IRC Mick you should come more often
[21:45] <MickMondo> yeah, Its a bit quite at work tonight so I thought I'd get on here,,, also wanted to ask about the rfm22
[21:45] Nick change: arko_ -> arko
[21:46] <MickMondo> is dave launching too
[21:46] <Upu> Yes I think he is
[21:46] <MickMondo> Altitude ..?
[21:47] <Upu> err I'm not sure tbh don't think so
[21:47] <MickMondo> I'm not worried honest lol
[21:47] <Upu> not unless he's going to try a 1200g
[21:47] <Upu> I suspect your confidence is well placed
[21:47] <Upu> that is a stupidly high altitude
[21:47] <MickMondo> yeah,,
[21:47] <MickMondo> so pleased I got that
[21:48] <MickMondo> It can be beaten though
[21:48] <MickMondo> down to the balloon like you said
[21:49] <MickMondo> I'm supprised the Americans havet tried latetly, its all us UK lot in the top ten
[21:49] <Upu> they seem really conservative
[21:50] <eroomde> are they still using kaymont?
[21:50] <Upu> interestingly I noticed they have a lightest payload chart
[21:50] <Upu> which I suspect we'd have the top 15 if we'd realised
[21:50] <MickMondo> havent looked at that
[21:50] <MickMondo> ahh bummer
[21:50] <Upu> 104g is their lightest
[21:51] <MickMondo> next time, list it with your flight Sunday
[21:51] <Upu> I have already
[21:51] <Upu> 35g
[21:51] <MickMondo> what .. ha ha
[21:51] <Upu> http://www.arhab.org/hab_launch_list.php
[21:51] <MickMondo> 104g
[21:51] <Upu> yeah
[21:51] <MickMondo> 35g is good
[21:51] <Upu> Dave's camera payload wasn't far off that
[21:51] <MickMondo> is that your new one
[21:51] <eroomde> they'd beat us on heaviness
[21:51] <Upu> yes
[21:52] <Upu> I know 22kg
[21:52] <eroomde> well actually, uk might have the #1 spot
[21:52] <Upu> like what are you launching ? Breakfast ?
[21:52] <eroomde> ahem
[21:52] <eroomde> but in general they have space and power anc have no reason to go light, lucky peeps
[21:52] <MickMondo> I'm trying to stay away fromn anything heavy now

[21:55] <MickMondo> I'm trying some new ideas and hoping for a payload of around 20g
[21:56] <MickMondo> perhaps a bit lighter
[21:56] <Laurenceb_> so i have some Dow Corning silicone PSA, and some contacts at Dupont who are very helpful
[21:56] <Upu> If I powered this from solar I think I could get this to 12g
[21:56] <Laurenceb_> should be feasible to put a balloon together
[21:56] <Laurenceb_> ive got some 80micron BiPET film
[21:56] <eroomde> coin cells must be worth attacking too
[21:56] <eroomde> they have the energy density
[21:56] <Laurenceb_> BiPET is interesting stuff
[21:56] <eroomde> just not the power
[21:56] <Upu> well interesting, that powered my badge for 2 days
[21:57] <MickMondo> I've got some solar panels ready for a float
[21:57] <Laurenceb_> i delaminated it with a scalpel
[21:57] <Upu> ok it was only blinking an LED
[21:57] <eroomde> sure
[21:57] <Laurenceb_> and ill shut up as no-one is interested :P
[21:57] <Upu> but for a battery I ripped from a 10 year old PC motherboard it did ok
[21:57] <Upu> I am Laurenceb just not tonight
[21:57] <Upu> going to log shortly
