[06:20] <SP9UOB-Tom> on the map
[06:21] <daveake> Sorry no access :(
[06:21] <SP9UOB-Tom> ah, ok
[06:21] <daveake> Upu will be up soon and he can do it
[06:21] <Upu> o7
[06:21] <SP9UOB-Tom> sure, thanks

[06:28] <daveake> Upu question: Since my flight is in habitat as 1 flight 2 payloads, and the payloads will fall independently, will both get live landing predictions?
[06:29] <Upu> yeah landing predictor isn't linked to Habitat afaik
[06:29] <daveake> ah cool
[06:29] <daveake> didn't think so wssn't sure
[06:30] <Upu> will sort that later

[06:48] <ibanezmatt13> Good Morning :)
[06:49] <ibanezmatt13> Zenith recovered?
[06:51] <jcoxon> morning
[06:51] <Martin__> I was chatting to the crew yesterday and afaik the payload is lost
[06:51] <ibanezmatt13> PI payload wasn't it?
[06:52] <Martin__> Yes, with Pi Cam
[06:52] <ibanezmatt13> ah that's a shame
[06:52] <Martin__> Yes, they're a tad fed up :(
[06:52] <ibanezmatt13> Did they have a backup tracker?
[06:52] <Martin__> Don't think so, but wouldn't swear to it
[06:53] <ibanezmatt13> I've been wondering what we're supposed to do when it gets below a certain altitude. We don't have Yagi antennas or anything you see..
[06:53] shenki (~joel@182-239-249-205.ip.adam.com.au) joined #highaltitude.
[06:54] <Martin__> Ask for advice on this forum (don't ask me I'm new at this!) :)
[06:54] <ibanezmatt13> In our case, we would have to rely on the last position somebody with a good setup and hope the GSM backup worked. Not a great plan really
[06:55] <Martin__> Will you have a chase team in the proximity?
[06:55] <ibanezmatt13> we will be chasing it ourselves :\
[06:55] <jcoxon> most of the time the payload will continue transmitting on the ground
[06:55] <ibanezmatt13> Just as we launch, we're driving to follow it so we have the best chance
[06:55] <jcoxon> and if you get within a mile or 2 of it
[06:56] <jcoxon> you'll decode a final string and easily find it
[06:56] <ibanezmatt13> How long will 6 Lithium AA's last with a Pi and Pi Cam roughly?
[06:56] <ibanezmatt13> That's what we're using
[06:56] <jcoxon> sometimes the yagi is a disadvantage
[06:56] <jcoxon> as the signal is too strong to direction find it
[06:56] <jcoxon> ibanezmatt13, no idea - you must test it before you launch
[06:57] <ibanezmatt13> We've got a vertical magmount for the car roof :)
[06:57] <ibanezmatt13> will do
[06:57] <jcoxon> yeah thats good (magmount that is)
[06:57] <jcoxon> for a fun project you could make a completely independent radio beacon
[06:57] <jcoxon> they've saved peoples payloads before
[06:57] <Martin__> In theory, an aerial with a nicely defined null, like an HB9CV is good for DF - you point the null at the source not the main lobe (or so I seem to remember from ham radio df hunts)
[06:58] <jcoxon> just have it tone on and off
[06:58] <jcoxon> attach it seperately to flight string
[06:58] <ibanezmatt13> Flight string?
[06:58] <Martin__> Anyone know how to change nickname in HexChat?
[06:58] <ibanezmatt13> is it not just /NICK
[06:58] <jcoxon> as in the main line from the balloon down to the payload
[06:59] <ibanezmatt13> ah right, so what about the coax cable?
[06:59] Nick change: Martin__ -> Martin_G4FUI
[06:59] <Martin_G4FUI> Ta :)
[06:59] <ibanezmatt13> :
[06:59] Last message repeated 1 time(s).
[06:59] <ibanezmatt13> :)
[06:59] <ibanezmatt13> damn keyboard
[07:00] <ibanezmatt13> That's what I was meaning to ask. Is the piece of RG58 coax cable going to be a good enough aerial for our payliad?
[07:01] <ibanezmatt13> payload*
[07:01] <jcoxon> ibanezmatt13, i assume at the end of the coax you'll construct an antenna
[07:01] <Martin_G4FUI> I suppose one can get TOO much advice - you might get to the point where you just say "WTF" and "JDI" and be prepared to learn the hard way
[07:02] <jcoxon> for a backup beacon this is what i did: http://www.flickr.com/photos/jcoxon77/4201006391/in/set-72157623226106480
[07:02] <jcoxon> and it saved the payload which had landed in the netherlands
[07:02] <ibanezmatt13> Does that involve the peeling back of the insulation to 16.4cm, creating 4 radials out of the braided wire etc... ? I've done that :)
[07:02] <jcoxon> ibanezmatt13, yeah
[07:02] <Martin_G4FUI> Zenith had a quarter wave monopole with 8 radials glued to the payload, I believe - it seemed to get out very well
[07:03] <ibanezmatt13> jcoxon, Is that your tracker?
[07:03] <jcoxon> that was an old backup beacon
[07:03] <Martin_G4FUI> Stratodean used drinking straws for mechanical stability (coax peeled back method)
[07:03] <ibanezmatt13> that's a good idea jcoxon
[07:03] <jcoxon> ibanezmatt13, it was an avr and a radio
[07:03] <jcoxon> just did a bit of morse
[07:03] <jcoxon> and would last for 4 days or so
[07:04] <ibanezmatt13> Wahat freq?
[07:04] <jcoxon> that ntx2 is .650
[07:04] <ibanezmatt13> different to the other NTX2 I guess?
[07:04] <jcoxon> yeah there are 2 models
[07:04] <ibanezmatt13> thought so
[07:04] <jcoxon> .075 and .650
[07:04] <jcoxon> and it landed here: http://www.flickr.com/photos/jcoxon77/4383328360/in/set-72157623226106480
[07:04] <ibanezmatt13> I've always wanted to be able to program those little ATMEGA chips, that's the only reason I'm learning C!
[07:05] <jcoxon> get an arduino uno and you are off
[07:05] <ibanezmatt13> woa, that's close
[07:05] <ibanezmatt13> yes I will :)
[07:05] <ibanezmatt13> In a tree or something?
[07:05] <jcoxon> when is your launch?
[07:05] <ibanezmatt13> August 17th approximately
[07:06] <jcoxon> what freq are you on with your payload?
[07:06] <ibanezmatt13> 0.75
[07:06] <jcoxon> i'll have a look to see what old ntx2 i've got
[07:06] <jcoxon> if iv'e got a 650 i'll made you a back up beacon if you want
[07:07] <jcoxon> i'll stick some hellschreiber on as that'll make people nostalgic and happy
[07:07] <ibanezmatt13> That would be absolutely amazing! Thank you very very much! :)
[07:07] <ibanezmatt13> I think for the first one, having that would be an excellent backup. Then for the second one I could make my own :) Thanks jcoxon
[07:10] <jcoxon> maybe if it all works you can pass it onto someone else afterwards
[07:10] <jcoxon> see how many flights it can be on
[07:10] <ibanezmatt13> of course :)

[07:31] <mfa298> ibanezmatt13: for range testing if you can get it relativly high in a tall tree that camn work as well
[07:31] <ibanezmatt13> Yeah I could do that
[07:32] <ibanezmatt13> I think the ultimate test it to try and pick up a HAB flight not too far away, but I still keep trying and failing
[07:32] <mfa298> daveake's new guide is also worth a read.
[07:32] <ibanezmatt13> new guide?

[07:34] <daveake> ^^ read this
[07:34] <ibanezmatt13> Thank you daveake, morning :)
[07:34] <daveake> morning :)
[07:35] <ibanezmatt13> Test that it reports the altitude correctly above 32,768 metres and below zero metres. ?
[07:36] <daveake> Yes
[07:36] <ibanezmatt13> How?
[07:36] <daveake> By faking the GPS data
[07:37] <ibanezmatt13> How do I do that?
[07:38] <mfa298> the flight i was thinking of is from birmingham tomorrow morning, Horizon 2
[07:38] <daveake> If you use a 16-bit signed in to store the altitude, it will go negative about 32768 (largest number you can hold in that type of variable)
[07:38] GW8RAK (~chatzilla@host-78-147-42-42.as13285.net) joined #highaltitude.
[07:38] <ibanezmatt13> need to change that then
[07:38] <daveake> And if it's an unsigned integer, an altitude of less than zero (OK that's unlikely in the UK) will produce a surprising result
[07:39] <ibanezmatt13> I think it's a float in my case, that ok?

[07:39] <daveake> What do you think?
[07:40] ghoti (~paul@scratch.it.ca) joined #highaltitude.
[07:40] <ibanezmatt13> err, ok I think
[07:40] <daveake> Then you'd be right
[07:40] <ibanezmatt13> Hone your tracking skills by tracking other people's flights. Don't make your own flight the first one you track yourself!
[07:40] <ibanezmatt13> I've still not achieved that
[07:41] <daveake> Keep trying
[07:41] <daveake> Might be your receiver is a bit deaf and you don't want to find that out on your own flight
[07:41] <ibanezmatt13> Possibly
[07:41] <ibanezmatt13> jcoxon said he may be able to contruct an AVR with a .650 NTX2 which I could attach to the bottom of the flight string.
[07:41] <mfa298> have you tried finding and talking to your local radio club.
[07:41] <ibanezmatt13> not yet
[07:42] <daveake> Yeah I saw that, which is what prompted me to mention it
[07:42] <ibanezmatt13> mfa298, probably a good idea, really need someone to check that it's ok
[07:42] <daveake> yup
[07:42] <mfa298> might be worth doing as you might be able to do some tests with someone and work out how good the reciever and antenna are
[07:43] <mfa298> you might even find someone who wants to help out or that can lend you a reciever
[07:43] <daveake> Or, put your tracker on upstairs then walk a mile down the road. If you still hear the signal clearly it's probably fine
[07:43] <ibanezmatt13> I thought it needed line of sighT?
[07:44] <daveake> Well it'll go through a building or two but so long as there's no hill in the way it'll work
[07:44] <ibanezmatt13> A mile? That's quite far but worth a try
[07:44] <daveake> 15 mins walk what's the problem?
[07:44] <daveake> Or get on your bike :)
[07:44] <ibanezmatt13> no problem, well worth it :)
[07:45] <daveake> Indeed
[07:45] <ibanezmatt13> bike sounds better
[07:45] <daveake> It also shows that your payload aerial is working
[07:45] ghoti (~paul@scratch.it.ca) left irc: Ping timeout: 256 seconds
[07:45] <mfa298> try recieving it as you move away from it but when it disappears try moving around that area a bit as you might find it comes back
[07:45] <ibanezmatt13> well, not built that yet but I'm gonna go to Maplin today and ask if they can crimp the connector I need onto some RG58
[07:46] ghoti (~paul@scratch.it.ca) joined #highaltitude.
[07:46] <ibanezmatt13> sounds like a plan mfa298
[07:46] <ibanezmatt13> will maplin sell male SMA connectors
[07:46] <ibanezmatt13> ?
[07:46] <ibanezmatt13> I assume not
[07:47] <daveake> If they have them they'll sell them
[07:47] <daveake> Didn't someone give you their part number?

[07:47] <daveake> No need to ask the same question more than once :)
[07:47] <ibanezmatt13> I wrote a number down yesterday, I'll check it out
[07:48] <daveake> http://www.maplin.co.uk/sma-crimp-plugs-26627
[07:48] <daveake> Just make sure you get the one for the cable you've got
[07:49] lz1dev (~rgp@46.47.80.192) joined #highaltitude.
[07:49] <ibanezmatt13> Would that fit the female SMA I got from Upu? I've got RG58
[07:49] <daveake> Yes
[07:49] <ibanezmatt13> Yeah it definitely fits the RG58
[07:49] <beingaware> http://au.element14.com/aurel/tx-mid-3v/rf-mod-tx-am-ook-3v-433-92mhz/dp/1699470
[07:49] <daveake> SMA is SMA (well aside from those damn reverse ones)
[07:49] <beingaware> yay or nay? ^
[07:50] <daveake> Just make sure you get the RG58 one if that's the cable you've got
[07:50] <ibanezmatt13> I'll ask Maplin to attach it to the cable for me (I don't have a crimp tool)
[07:50] <ibanezmatt13> They do things like that in the back I believe
[07:51] <daveake> Yeah just ask I'm sure they'll help
[07:51] <ibanezmatt13> good stuff, saves me a job
[07:51] <daveake> Also, ask at the radio club someone may have a spare crimp tool
[07:52] <ibanezmatt13> To be honest, my granddad thought he had one and didn't, so I'm sure he's gonna get himself one (I do all soldering, contruction work at his house.) I cut the foam using a proper tool ;)
[07:52] <ibanezmatt13> The panel saw
[07:53] <daveake> He sounds like a great help to you
[07:53] <ibanezmatt13> He certainly is
[07:53] <ibanezmatt13> He bought me some stuff for the project too, and he's coming chasing it for us :)
[07:53] <number10> ibanezmatt13: what connector do you require at the other end of your cable?
[07:54] <ibanezmatt13> I guess a male SMA

[07:54] <ibanezmatt13> http://ava.upuaut.net/store/index.php?route=product/product&path=71_66&product_id=74
[07:54] <ibanezmatt13> That's already soldered onto the stripboard
[07:54] <ibanezmatt13> That's what I'm connecting to
[07:55] <number10> is that for your antenna on the payload?
[07:55] <ibanezmatt13> That what I just linked you to is on the NTX2
[07:55] <ibanezmatt13> I need a connector to go into that from the coax cable
[07:56] <ibanezmatt13> http://www.maplin.co.uk/sma-crimp-plugs-26627
[07:56] <daveake> ibanezmatt13 Ask at Maplin today but if you get stuck let me know I'll make you a cable
[07:56] <number10> well there is a nice offr ibanezmatt13
[07:56] <ibanezmatt13> I'm sure they'll be able to put the connector one. But on the piece of RG58 I practised on I think I messed it up. Not as easy as I thought. I'll have a go first
[07:56] <ibanezmatt13> Thanks for that daveake
[07:56] <daveake> It'll probably be RG174 as I don't think I have any RG58 SMA plugs, but for the short distance it'll be just ifine (it's what I use all the time)
[07:57] <ibanezmatt13> sounds good :)
[07:57] <daveake> And yes radio plugs can be a PITA to crimp or solder
[07:57] <costyn> morning all
[07:57] <daveake> gm
[07:57] <costyn> daveake: I don't think I've ever seen so many changes and updates to a launch announcement :P
[07:58] <daveake> lol
[07:58] <daveake> I think I'll give up and just do a "vague" announcement like Steve :p
[07:58] <costyn> well whatever it takes for a succesfull launch of course
[07:58] <costyn> hahah yea
[07:58] <daveake> "might be launching somethine sometime soon"
[07:59] <daveake> somewhere
[07:59] <costyn> nice writeup on the wiki about recovery
[07:59] <daveake> cheers been meaning to do that for a while
[07:59] <daveake> well, since the last lost payload
[07:59] <costyn> might worry some newcomers who think they have to have all of it though :)
[07:59] mikestir (~quassel@cpc10-brmb8-2-0-cust107.1-3.cable.virginmedia.com) joined #highaltitude.
[07:59] <costyn> since the list is quite comprehensive
[07:59] <daveake> ha
[07:59] <daveake> well
[07:59] <daveake> the more you do the better your chances
[08:00] <costyn> indeed
[08:00] <eroomde> well, i was a bit surprised recently that people chase without a radio and laptop
[08:00] <eroomde> or just wait for it to land before heading out
[08:00] <number10> if you are making up an antenna, and dont want a connector on the antenna end you could buy something like one these and cut the unwanted connector off http://www.ebay.co.uk/itm/6M-Antenna-RP-SMA-Extension-Cable-WiFi-Wi-Fi-Router-/260741842445?pt=UK_Computing_Boosters_Extenders_Antennas&hash=item3cb56cc60d
[08:00] <eroomde> i.e. not chasing
[08:00] <number10> then you have a length of spare cable to practice making the antenna
[08:01] <costyn> well if you have only 30km to go, and the flight is going to take 2.5 hours, there's a case for not heading out immediately
[08:01] <ibanezmatt13> love that write up on the Wiki daveake
[08:01] <eroomde> if you just say 'PRETEND YOU'RE ON YOUR OWN' that covers most of it
[08:01] <daveake> But many are essential really, and on so many first-time flights some (like coming on IRC) people just don't do
[08:01] <number10> I heard that on a recent launch the chase team headed off to the pub --- terrible
[08:01] <daveake> terrible
[08:01] <Upu> lol
[08:02] <costyn> I've linked Stirks to the glossary for people who aren't familiar with the term yet :)
[08:03] <daveake> Ah cheers
[08:03] <Upu> :/
[08:03] <daveake> It took long enough to type that lot up I was too tired/lazy to do the links :)
[08:03] <costyn> I can imagine :)
[08:03] <ibanezmatt13> daveake, on the wiki you talk about having a Yagi. But I heard that at close range they're pretty useless. Is it definitely worth me getting one?
[08:04] jijdaar (9117fea1@gateway/web/freenode/ip.145.23.254.161) joined #highaltitude.
[08:04] <daveake> If you're "too close" you don't need it :)
[08:04] <eroomde> you use 'definitely' too much for engineering
[08:05] <ibanezmatt13> Yeah, ok :)
[08:05] <eroomde> if you want definite you should do maths :)
[08:05] <daveake> Saved me on my first flight
[08:05] <ibanezmatt13> Am doing :)
[08:05] <ibanezmatt13> I guess if I get one it doesn't have to be expensive
[08:05] <daveake> Ask at the radio club someone may have a spare one
[08:05] <daveake> Or you could make one
[08:06] <Martin_G4FUI> Engineers used to use slide rules, AKA "Guessing Sticks"
[08:06] <ibanezmatt13> make a yagi?
[08:06] <daveake> Personally I CBA so I bought one
[08:06] <ibanezmatt13> Depends how much they are. I don't know what sort I need
[08:06] <daveake> A ham will be along any moment now to say "No need to buy one you can make one from bits of wire for thrupence"
[08:07] <costyn> haha
[08:07] <ibanezmatt13> I think I'll go for getting one :)
[08:07] <daveake> A small yagi will do fine. You don't want something large as it will be difficult to handle
[08:07] <eroomde> make sure it fits on the parcel shelf
[08:07] <ibanezmatt13> Do they come under certain names. I heard elements being mentioned a liot
[08:07] <ibanezmatt13> lot*
[08:07] <eroomde> that's basically my metric for a car-yagi
[08:07] <daveake> If when chasing all you can get is a weak signal, a Yagi will get a decode for you
[08:08] <eroomde> yes, elemtns are the number of cross-bits
[08:08] <eroomde> and the more the number, the longer the yagi
[08:08] <costyn> ibanezmatt13: http://www.ebay.nl/itm/70cm-7-ELEMENT-SPECIAL-YAGI-ANTENNA-430-440MHz-/121109985978?pt=UK_Mobile_Phones_Communication_Radio_Antennas&hash=item1c32b7baba#ht_500wt_885
[08:08] <eroomde> maybe look for a 3/4/5 el
[08:08] <daveake> Yup and as eroomde says get one that fits on the parcel shelf :)
[08:08] <costyn> ibanezmatt13: the moonraker zl special antenna is nice and sturdy and not too expensive
[08:08] <ibanezmatt13> costyn, thanks, but I think I'll get one less than 7 :)
[08:09] <costyn> ibanezmatt13: there are very few with less
[08:09] <mfa298> too some extend you can't take too much kit and a yagi is a good part on that kit, just accept that you might not need it this time (but the time you don't have it is when you'll need it)
[08:09] <GW8RAK> Costyn, aren't they difficult to tune. Someone on here had problems.
[08:09] <Martin_G4FUI> This one looks nice for those with deep pockets :- http://www.arrowantennas.com/arrowii/440-5ii.html
[08:10] <Martin_G4FUI> Nice concept tho
[08:10] <eroomde> http://uk.farnell.com/lprs/yagi-434a/antenna-yagi-7-element-434mhz/dp/2096215?Ntt=434+yagi
[08:10] <eroomde> 1m long
[08:10] <daveake> Oh yeah there's loads of kit in my chase car that comes back unused. But it all gets used sooner or later!
[08:10] <ibanezmatt13> eroomde, that looks a good option
[08:11] <GW8RAK> I've heard good reports about this homebrew one http://www.g6lvb.com/homebrewarrow.htm
[08:11] <GW8RAK> Just leave off the 2m bits
[08:11] <ibanezmatt13> I don't really want to loose this payload so I'm gonna see what I can get
[08:12] <daveake> Also ibanezmatt13 I don't know if anyone else up there could come out chasing with you, but if so then you don't need to buy kit they already have
[08:12] <Martin_G4FUI> "Image is for illustrative purposes only" That always gets me going ...
[08:12] <ibanezmatt13> I was thinking of coming down to Cambridge in the hope that some people could help me :\
[08:12] <Martin_G4FUI> Like "This Page Intentionally Left Blank"
[08:12] <daveake> Ah in that case you're sure to have help
[08:13] <ibanezmatt13> So I don't need one then. That's saved me a bit
[08:13] <daveake> heck might even come over myself
[08:13] <ibanezmatt13> I'll get one at some point though
[08:13] <ibanezmatt13> That would be simply excellent
[08:14] <ibanezmatt13> My Dad said that he doesn't feel that we'll be able to string it all up ourselves :)
[08:14] <daveake> Hah yes you could :)
[08:14] <daveake> But yeah if you launch from one of the Cambs sites then there'll be experienced people there to help
[08:14] <ibanezmatt13> Could, but it would probably datech from the balloon after 2 mins of flight
[08:15] <number10> we can even put a second small tracker on it for you if you want ibanezmatt13
[08:15] <ibanezmatt13> I think jcoxon may be making me a backup AVR
[08:15] <number10> ok thats cool
[08:15] <ibanezmatt13> He said to just pass it on to people who are flying when I'm done, which is great :)
[08:17] <daveake> Well that's great, but for an extra 100g someone here could add a small tracker
[08:17] <ibanezmatt13> That would be nice too, but I'm really pushing weight a bit
[08:17] <ibanezmatt13> Already on 780g
[08:18] <daveake> 100g won't make much difference
[08:18] <ibanezmatt13> Saying that, I'm making my box smaller
[08:18] <number10> whats in it so far
[08:18] <ibanezmatt13> NTX2, Ublox, two regulators, Pi, Pi Cam, battery back (for 6 AAs)
[08:18] <daveake> Well mine today is 900g - 2 trackers, box, lion, GoPro
[08:18] <Upu> ibanezmatt13 you can have a pava in a ball for backup
[08:19] <ibanezmatt13> I've seen those, they look good

[08:19] <Upu> I found out you can get launch permission up North
[08:19] <Upu> you just have to be careful where and there are stipulations on the NOTAM
[08:19] <Upu> like it can only go north
[08:19] <ibanezmatt13> that's good, but there's not many people up here to be fair and the transatlantic flight path comes very near
[08:20] <number10> whats you location ibanezmatt13
[08:20] <number10> +r
[08:20] <ibanezmatt13> Wigan near Manchester.
[08:20] <ibanezmatt13> Prepared to travel though
[08:20] <eroomde> that's north isn't it
[08:21] <ibanezmatt13> My Dad says he wouldn't mind going to Cambridge, he just wants us to go to the place we're likely to get good help and recover it
[08:21] <ibanezmatt13> Yes North
[08:21] <Upu> Cambridge is probably the best place to launch from
[08:21] <number10> well cambridge is a good place
[08:21] <ibanezmatt13> Cambridge it is
[08:21] <Upu> great coverage, no major airports and lots of farmland
[08:21] <daveake> And you get photos of the sea
[08:22] <daveake> Soetimes from close up and personal
[08:22] <number10> and fish and chips
[08:22] <ibanezmatt13> daveake, do you launch in your back garden?
[08:22] <daveake> almost lol
[08:22] <ibanezmatt13> Lucky :) Always wondered that from videos

[08:39] <ibanezmatt13> He didn't know what an SMA connector was
[08:39] <eroomde> the rs website is so terrible

[08:39] <eroomde> 60mA > 6A according to their parametric search
[08:39] <ibanezmatt13> What a pile of crap
[08:39] <eroomde> don't bother with the people there
[08:40] <eroomde> just buy the parts
[08:40] <ibanezmatt13> Well, I'm not sure about doing it myself anyway
[08:40] <ibanezmatt13> It's the one thing that needs to be right otherwise tracking it won't be very easy

[08:40] <mikestir> trade counter opens sat am i think
[08:41] <ibanezmatt13> could do I guess.
[08:41] <Martin_G4FUI> ISTR you don't need an account with Farnell in order to buy stuff online
[08:42] <ibanezmatt13> I can get the parts but I'm not sure about preparing the aerial myself. It didn't go well the first time
[08:42] <eroomde> indeed but free shipping
[08:43] <number10> ibanezmatt13: that is one thing you need to get roght.. practice and test - make it robust
[08:43] <number10> right
[08:44] <ibanezmatt13> I'll get the parts, practise, and if it goes wrong, I'll just see what I can do
[08:44] <number10> if you can - use the cusf idea of having some pipe insulation protecting the radiator
[08:44] <ibanezmatt13> I got this far http://sdrv.ms/139Soyx
[08:45] <ibanezmatt13> ready to solder 4 wires on for radials
[08:45] <ibanezmatt13> Instead of spliting the braid into 4 sections
[08:45] <mfa298> the other way of finding somewhere that might put the connector on a cable for you is a ham radio shop (if there's one fairly close to you)
[08:45] <number10> soldering on the radials is fine
[08:45] <ibanezmatt13> I could do yes.
[08:46] <ibanezmatt13> Are there any stores that will do it? Like Maplin but not Maplin because they're shockingly terrible
[08:46] <mikestir> can you not get a pre-made lead and cut it in half?
[08:46] <daveake> An amateur radio store but dunno if you have any there
[08:47] <number10> it has been suggested - ebay have made up ones for less than 2 quid
[08:47] <mfa298> the only places that I could think of that are ooop norf (as far as I'm concerned at least) are radioworld (birmingham) and Lam (Barnsley)

[10:24] <Upu> just a point ibanezmatt13 that capacitor by the GPS, it has a decoupling capacitor on the board
[10:25] <Upu> not going to harm anything
[10:25] <daveake> Personally, I like to keep switching regulators a but further away from the GPS antenna
[10:25] <daveake> bit
[10:26] <BenBancroft> I would consider mounting them to the battery case
[10:27] <daveake> BenBancroft Did you get any signal at all when you got to near the landing spot yesterday?
[10:27] <BenBancroft> nope
[10:27] <BenBancroft> but I have a feeling where it landed
[10:27] <daveake> Shame should have been findable if so
[10:27] <daveake> Remind me, model A or B Pi?
[10:28] <BenBancroft> model A
[10:28] <ibanezmatt13> How far is a bit away? Not really much room for maneouvere and having so many wires coming up from the bottom may be an issue
[10:28] <daveake> OK, and what was the power setup?
[10:28] <BenBancroft> 4 AA lithium and two switching regulators same as in picture above
[10:28] <daveake> ibanezmatt13, Move the top one to same distance from the GPS as the bottom one
[10:29] <daveake> OK so removed the Pi reg?
[10:29] <BenBancroft> yes
[10:29] <daveake> OK
[10:29] <daveake> And any 5V devices? i.e. USB?
[10:29] <BenBancroft> the uv sensor was
[10:29] <daveake> Ah OK
[10:30] <daveake> Otherwise you don't need the 5V rail
[10:30] <BenBancroft> yh
[10:30] <BenBancroft> Got some excellent data mind
[10:30] <BenBancroft> very pleased with it
[10:30] <daveake> Next time add an extra AA or 2
[10:30] <BenBancroft> ok
[10:30] <daveake> You probably suffered from the dropout voltage on those regs being too high
[10:31] <BenBancroft> I recon the aerial snapped of when hit tree
[10:31] <daveake> IIRC it's 1.5V which means you need 4.5V from the batteries minimum
[10:31] <daveake> Aerial was what construction?
[10:31] <Lunar_LanderU> Upu: have a moment for a ublox question?
[10:31] <daveake> The "shagi" design won't break
[10:31] <BenBancroft> external 1/4 monopole
[10:31] <BenBancroft> with 8 radials
[10:32] <daveake> OK was the pole bit soldered on?
[10:32] <Upu> Just ask Lunar_LanderU I doubt I'm the only person who knows the answer
[10:32] <BenBancroft> yes
[10:32] <Lunar_LanderU> ok
[10:32] <daveake> I did that once
[10:32] <daveake> Never again
[10:32] <daveake> Fell off during descent
[10:32] <Lunar_LanderU> my code that always worked before now just gives a navmode of 0, no advancing time reading and the error code 8
[10:32] <ibanezmatt13> daveake, worryingly I am keeping the normal reg on my Pi which means I have to power it straight with 5v... With 6AA's I'm starting to doubt my chances
[10:32] <Lunar_LanderU> and I don't know why
[10:32] <BenBancroft> I recon its here
[10:32] <BenBancroft> https://dl.dropboxusercontent.com/u/37357280/landing%20zone.png
[10:33] <Lunar_LanderU> just plugged in the batteries and get that on dl-fldigi
[10:33] <daveake> ib Use 6AAs it'll be fine
[10:33] <BenBancroft> I never checked the area as was too dense
[10:33] <daveake> ibanezmatt13, ^^
[10:33] <ibanezmatt13> at 5v even with 6 AA's

[10:34] <daveake> I'm confused

[10:34] <ibanezmatt13> 3.3v to the NTX2 and UBLOX
[10:34] <daveake> Oh OK
[10:34] <daveake> Well
[10:34] <ibanezmatt13> Because the 3.3v line on Pi is bad

[10:35] <daveake> If you feel up to it
[10:35] <daveake> Chop the legs off the Pi reg and apply 3.3V directly
[10:35] <daveake> If you don't feel up to it don't!
[10:35] <BenBancroft> Btw about partitioning the SD card, I did that on mine
[10:35] <BenBancroft> Mind I never got video back
[10:35] <ibanezmatt13> I want to do that but I'm probably gonna destroy the Pi
[10:35] <daveake> OK
[10:36] <ibanezmatt13> How would I do that?
[10:36] <mfa298> BenBancroft: I think there's a few bits of video footage stuck in the tops of trees
[10:36] <daveake> If you need to ask, don't do it :)
[10:36] <ibanezmatt13> simply very good wire cutters?
[10:36] chrisstubbs (~chrisstub@host86-130-222-249.range86-130.btcentralplus.com) joined #highaltitude.
[10:37] <ibanezmatt13> I think I know what to do but I just want to be sure. I just need to cut using wire cutters the two outer legs on the RG2 near that capacitor?
[10:37] <BenBancroft> If only I could go back and get it, but got no way to get back now
[10:37] <daveake> Yes and solder a wire on to apply 3.3V to the 3.3 and 5V rails
[10:37] <BenBancroft> and them trees were very tall
[10:37] <ibanezmatt13> So I can't power the Pi through the GPIO if I cut those legs?
[10:38] <daveake> Yes you can
[10:38] <mfa298> if it's in the topof a tree it helps to have a few good gps strings from the payload so you can work out which trees to look in.
[10:38] <daveake> Cut the legs and apply power through those pins np
[10:38] <ibanezmatt13> I don't need 5v do I? Just power it through the 3.3v pin? Or do I give 3.3v into the 5v pin
[10:38] <daveake> BenBancroft Even without aerial I reckon you'd have decoded if it was still transmitting
[10:38] <gonzo_> any news from the hf hab at FDH?
[10:39] <BenBancroft> The truth is I never took the laptop down that track, I was two miles away when I used it
[10:39] <BenBancroft> As you couldnt get car down that track due to a metal gate
[10:40] <daveake> Yeah a tablet or netbook is much better for that
[10:40] <daveake> Or take a backpack
[10:40] <ibanezmatt13> Think I got it now. Wire cutters to cut the two outer legs on RG2 on the Pi, then give 3.3v to the Pi's "5v" pin. Not what I would have expected but I guess that's it
[10:41] <mfa298> if it was still transmitting and was in the top of a tree you might have heard it from a couple of miles even if the antenna was damaged
[10:41] <daveake> The Pi senses the 5V line and won't boot unless you put something there. Tie it to the 3.3V line.
[10:41] <Lunar_LanderU> Upu: got it
[10:41] <Lunar_LanderU> GPS GND wire came off the solder point
[10:41] <daveake> With that, you can run the lot from a single regulator
[10:41] <Upu> yes you need those Lunar_Lander
[10:42] <ibanezmatt13> daveake, sorry that confused me a bit. You want me to physically connect the Pi's 3.3v pin to the Pi's 5v pin?
[10:44] <daveake> yes
[10:45] <daveake> and apply 3.3V from the regulator
[10:45] <daveake> not 5V bad things will happen
[10:45] <BenBancroft> You still lauching this weekend daveake?
[10:45] <ibanezmatt13> So on stripboard, I give 3.3v to both 3.3v pin and 5v pin. But I guess I can do that by having a 3.3v line from the reg and connecting both pin 1 and pin 2 to that?
[10:45] <daveake> 4:30pm yes

[12:02] <Lunar_LanderU> that same scanner also thinks arduino 1.0.5 has one
[12:02] <Lunar_LanderU> so I think that is a crap reading
[12:02] <SpeedEvil> Arduino _is_ a trojan.

[12:10] <Lunar_LanderU> yeah :P
[12:11] <fsphil> (smugness may end if one of my machines gets rooted)
[12:14] <Lunar_LanderU> yea
[12:14] <Lunar_LanderU> hopefully not :)
[12:15] <fsphil> well to be fair I haven't had a compromised windows machine in a while either
[12:15] <fsphil> but I don't download much software at work
[12:15] <Lunar_LanderU> yeah
[12:15] <mfa298> windows seems to be a lot better than it used to be in that area
[12:16] <Jess--> no compromised win machines in 3 years (that's out of 6 real machines and 32 virtual ones which are all live on the net)
[12:16] <mfa298> I think most attacks now are from compromised websites or dodgy software
[12:17] <fsphil> I don't use IE which probably helps
[12:17] <mfa298> I think I've had more *nix machines broken into than windows, although that's usually from silly mistakes (test accounts with test passwords)
[12:17] sq3bmw (b2eb5169@gateway/web/freenode/ip.178.235.81.105) left irc: Quit: Page closed
[12:17] <Jess--> I think with windows having had most of the attacks in the past most users are aware of the attack vectors
[12:17] <fsphil> I remember WinXP (pre SP2) could be compromised simply by being online
[12:17] <mfa298> It's always fun watching the attackers when they get a Solaris box instead of linux.
[12:18] <fsphil> I accidently dialed up on a fresh install, and within a minute without me doing anything it was infected
[12:18] <Jess--> actually I lied before, I do have one machine that appears to be compromised (it's a honeypot, anything connecting to it is instantly blocked from anything else on my network)
[12:18] <mfa298> I remember when one of the big viruses was out. doing network builds the machine was compromised before the installer had completed
[12:18] <daveake> Did that once on a Win2000 machine that I had to replace the HD on, in a hotel in Saudi. Dualled up for soemthing 5 mins later virus
[12:19] <fsphil> I think it was the same one mfa298
[12:19] <fsphil> it got in through a message system
[12:19] <Jess--> sounds like the days of nimda or codered daveake
[12:19] <fsphil> where you could send messages between windows machines

[12:19] <mfa298> fsphil: there were a couple like that in the early 2000's
[12:20] <fsphil> I did catch people downloading files from a samba share on an old linux box once, after I'd forgotten to firewall it off from the WAN interface
[12:20] <Lunar_LanderU> btw
[12:20] <Lunar_LanderU> how did the old XP get infected just by being online?
[12:20] <Lunar_LanderU> how could that happen
[12:21] <fsphil> it used to have no firewall
[12:21] <fsphil> all ports where open online
[12:21] <fsphil> well ports with a service running
[12:21] <mfa298> and the file/print sharing was on and listening by default and had lots of bugs in it
[12:21] <daveake> Jess-- Really can't remember was quite a while ago
[12:21] <fsphil> the one I got basically caused the machine to shutdown after a minute
[12:22] <Lunar_LanderU> and then the bad guys just waited in the internet that one of these got connected and sent the malware?
[12:22] <fsphil> they scanned IP addresses for the relevent open port
[12:22] <fsphil> I say they, other infected machines too
[12:22] <mfa298> Lunar_LanderU: with a couple of the viruses a lot of machines were infected and they just scanned network ranges for stuff to infect.
[12:22] <Lunar_LanderU> ah
[12:23] <Lunar_LanderU> yeah we had XP SP1 on our 2003 PC
[12:23] <Jess--> I remember trying to clean nimda from a network of 200 machines while also having to keep the machines connected so that business could continue, impossible to do, ended up having to wait until 5pm and then pull the whole lot offline
[12:23] <Lunar_LanderU> remember that we ordered the SP2 CD from Microsoft when it came out
[12:23] <Jess--> the only machines we managed to keep online were 2 old NT4 servers
[12:24] <mfa298> with the messaging application running on XP it also made it easy to tell people they were infected. I ended up writing various scripts that sent messages to people telling them to contact the service desk.
[12:24] <fsphil> cute
[12:24] <Lunar_LanderU> yea
[12:24] <fsphil> we where naughty kids, wrote a program to send many many messages at once to one machine :)
[12:24] <Lunar_LanderU> XD
[12:25] <Jess--> wouldnt have been the teachers machine by any chance fsphil?
[12:25] <fsphil> actually no. closest we got to that was to randomly open and close the CD-ROM tray of the network admin's machine
[12:25] <mfa298> Jess--: I think we ended up just blocking all of 135/445 etc. on the routers and then put rules in to allow access to a couple of core servers, wasn't a fun virus to clean up, especially when the only sensible rebuild method was pxe.
[12:25] <fsphil> just to freak him out a bit
[12:25] <fsphil> cause franky he wasn't doing his job right if we could do that :)
[12:26] <daveake> I wrote a password collector at Uni
[12:26] <daveake> Made the mistake of telling someone
[12:26] <fsphil> doh!
[12:27] <daveake> Who set me up with my own work
[12:27] <fsphil> we got the network admin's password the same way
[12:27] <daveake> Which at least shows it was convincing :)
[12:27] <fsphil> lol
[12:27] <daveake> Yeah ditto
[12:27] <fsphil> worst we did was the cd-rom thing
[12:28] <fsphil> and removing permission to our home folders for the teachers to see our files
[12:28] <daveake> :)
[12:28] <fsphil> which they did ask us about, but natrually we knew nothing
[12:28] <daveake> hah :)
[12:28] <Jess--> we did scheduled task (every 7 minutes) cupholder.exe
[12:28] <Jess--> all it did was open the cd tray (on every machine)
[12:28] <fsphil> oh sweet
[12:29] <fsphil> the classroom PCs only had floppy drives sadly
[12:29] <Jess--> quite impressive to hear every cd tray in an it suite opening in perfect harmony
[12:29] <mfa298> I remember at college changing changing the win3.11 settings to it treated other extensions as executable so we could hide applications (the teachers just looked for *.exe)
[12:29] <daveake> I once ran an MS-DOS course. Spent 5 mins lecturing people not to accept a diskette from anyone without checking it was clean. 5 mins later I handed them a diskette with something to try. Silly buggers all fell for it.
[12:29] <fsphil> we did do a syncronised degause
[12:29] <fsphil> nice to see the lights in the room blinking at the same time
[12:29] <fsphil> lol
[12:30] <daveake> This one made all the characters on the screen fall to the bottom and pile up
[12:30] <fsphil> degauss even
[12:30] <daveake> So they all rebooted

[12:30] <daveake> and it came back of course
[12:30] <daveake> 1 of 20 figured out to remove it from autoexec before I explained
[12:31] <Jess--> I still remember the trick of booting windows 3.11 with the shift key held down (to prevent startup tasks from running)
[12:32] <mfa298> I think we also customised the win.com file so it had a custom start up screen for win3.11
[12:32] <Jess--> mind you on 95 - xp machines it's always fun to change the shell for something completely different (in win.ini or the registry)
[12:33] <GMT> you youngsters with your viruses! never had them on mainframes
[12:33] <daveake> er

[12:48] <ibanezmatt13> I don't know what to do :(
[12:49] <ibanezmatt13> Upu: Does this mean I'll need another?
[12:49] <Upu> thats not good
[12:50] <Upu> how did that happen ?
[12:51] <ibanezmatt13> I was showing something to my Dad and I noticed that it wasn't aligned with the rest of the board. Perhaps the way it was soldered onto the board was exerting too much pressure. I really don't know
[12:51] <Upu> is it soldered to the board ?
[12:51] <ibanezmatt13> Unfortunately

[12:53] <jcoxon> is SP9RQA actually going to fly?
[12:54] <ibanezmatt13> Everything was soldered onto there, NTX2 and everything. Can't exactly afford to replace them, so I'll have to post them and hope for the best. How shall I post it?
[12:54] <Upu> Pack it up well
[12:54] <Upu> and post preferably recorded to me
[12:55] <Upu> my address is on the back of the packet if you still have it

[13:12] <chrisstubbs> yeah that will be the next thing on my list, can it actually power the tracker ;)
[13:12] <number10> to get 80Ma out of that one you need vin > 1v6

[14:41] <G0TDJ_Steve> Coincedentally, ISS is overhead at about 4:10 BST
[14:42] <fsphil> ATV repeaters are allowed to broadcast
[14:42] <fsphil> but that's an exception to the normal license
[14:42] <chrisg7ogx> no monetary gain
[14:43] <mfa298> it's also generally going to be broadcasting to other amteurs and for the allowed purposes in the license conditions
[14:44] <Willdude123> And also, why not have DTV repeaters?
[14:45] <mfa298> the A in ATV is Amateur, Some of the ATV repeaters are Digital, Some Analogue, some do both
[14:45] <Willdude123> Ah right.
[14:45] <Willdude123> Also, is it possible to broadcast FSTV from a HAB?
[14:46] <fsphil> yes in theory, but not in the UK
[14:46] <mfa298> if you can find a bit of radio spectrum that has enough bandwidth and power you could (but without buying the spectrum I don't think there is any currently)

[14:47] <G0TDJ_Steve> Not sure but it's the right day
[14:47] <mfa298> just have to hope the talks with rsgb and ofcom have some progress and maybe we might get to use some ham allocations airborne...

[14:48] <G0TDJ_Steve> No, just looked on Southgate site. Contact was scheduled for 11:50UTC
[14:50] <GMT> G0TDJ_Steve: okay, missed that one then! I will have a listen on this pass to see if I can hear anything
[14:51] Action: jcoxon still hasn't recevied his new radio to use on his ISS aprs balloon payload
[14:52] <number10> from china jcoxon ?
[14:52] <jcoxon> nope UK
[14:52] <number10> thats unusual
[14:52] <jcoxon> the tracking code says they tried to deliver it
[14:52] <jcoxon> but there is no red card
[14:52] <jcoxon> so i can't go claim it
[14:52] <G0TDJ_Steve> 9I@m just setting up to receive telemetry from Purley
[14:52] <number10> oh - not good
[14:52] <jcoxon> yeah
[14:52] <jcoxon> i've asked for a redelivery
[14:52] <jcoxon> i think
[14:53] <jcoxon> for monday
[14:53] <Willdude123> jcoxon: Ooh, sounds interesting. Would the HAB track the ISS over APRS? Can't you do that from the ground?
[14:53] <jcoxon> nope, the balloon would use the ISS to digipeat its position using APRS packets
[14:54] <jcoxon> so it would go balloon -- > iss --> ground station
[14:54] <fsphil> the ground stations would listen to the ISS rather than the payload
[14:54] <Willdude123> Nice, is that legal in the UK?
[14:54] <jcoxon> nope
[14:54] <Willdude123> So I presume you're doing it elsewhere.
[14:54] <jcoxon> its for long duration flights
[14:54] <Willdude123> Ah right.
[14:54] <jcoxon> so it would be used out to sea
[14:55] <jcoxon> there is no point using it in the UK
[14:55] <jcoxon> as there aren't that many passes
[14:55] <jcoxon> you'd get say 5 packets a day

[16:26] <ibanezmatt13> I see
[16:27] <m3eav> my internet is all on my phone, AYCE on three 15 quid a month PAYG, I use massive data
[16:27] <m3eav> never used a dongle, complete rip[ off
[16:27] <fsphil> I'm a bit annoyed the nexus 7 can't tether
[16:27] <LeoBodnar> Wow, POPs outside temperature below absolute zero
[16:28] <m3eav> it can't fsphil?
[16:28] <Willdude123> Hi.
[16:28] <m3eav> use a hacked ROM
[16:28] <Willdude123> Is there a problem with the launch?
[16:28] <Martin_G4FUI> I hope dave didn't say anything naughty when the string broke!
[16:28] <fsphil> could do m3eav, but not bothered enough yet
[16:28] <ibanezmatt13> Upu_M0UPU: I wrapped it several times in bubblewrap, then made a plywood box out of some small pieces of plywood, masking taped it all together, then put it into an already bubblewrapped bag. Should be ok
[16:28] <fsphil> I can use my htc
[16:28] <m3eav> no tether even on ON usb?
[16:29] <fsphil> don't believe so
[16:29] <Willdude123> When is the launch?
[16:29] <fsphil> the htc does but I've never got it working - use wifi instead
[16:29] <GMT> shortly
[16:29] <mfa298> m3eav: only works if you've got the right package on three (I got the one that's unlimited internet but no tethering) but then they're PAYG12 option isn't bad for occasional use
[16:29] <m3eav> Lol, i got the same but I use massive data;-)
[16:30] <m3eav> they throttle you down between midday and midnight if you get mega greedy
[16:30] <ibanezmatt13> looks like POP1 is trying to make it to Franc
[16:30] <ibanezmatt13> e
[16:30] <fsphil> I will have to try them. O2 is annoying
[16:30] <fsphil> are*
[16:30] <m3eav> but i have used probably several GB a day
[16:31] <fsphil> I'm a very occasional user
[16:31] <fsphil> but when I do use it, I use a lot
[16:31] <m3eav> I have another smart hnoe for CCTV use etc, usually pretty reliable
[16:31] <Willdude123> How long into the flight will it be when it's at oakley?
[16:32] <m3eav> POP? is this on test i presume?
[16:32] <GMT> Willdude123: prob about 1 hour, maybe slightly more
[16:33] <Willdude123> Can only use my wire atm, took the socket off one end of the coax.

[16:34] <m3eav> if pop was going i woudl get a sweet signla from it where i am right now:-)
[16:35] <G0TDJ_Steve> Is POP not launching then?
[16:35] <m3eav> dunno?
[16:35] <mfa298> Willdude123: as long as you have the wire from the centre of the coax going vertically (or close) you would hopefully be able to hear something
[16:36] <craag> POP won't be launching today.
[16:36] <craag> Matt will be testing it for Monday.
[16:36] <G0TDJ_Steve> OK Thanks craag
[16:36] <Willdude123> M0J
[16:36] <Willdude123> Wait
[16:36] <Willdude123> Oops
[16:36] <LeoBodnar> Looking at foil floaters, what causes them to float higher during the daytime? Lift should be the same if air density outside is the same... http://ukhas.org.uk/_media/projects:picoatlas:altitudegraph.png
[16:36] <mattbrejza> in fact if you refresh, its magically disappeared
[16:36] <m3eav> oooh aliens
[16:36] <Willdude123> M0JCM_Neil: Are you ready to track.
[16:36] <mfa298> Willdude123: It might also help if you have some radial wires on it as well (connected to the braid/screen part of the coax)
[16:37] <G4MYS_Andy> POP1 is about a mile from me those are high buildings say were looking at GPS noise seems a strange place to wander about with a ballon sending data possably in the rather nice gardens being Uni just to the east od f the scrub on southampton common so you wont herar it
[16:37] <Willdude123> Does 5:40 count as 4:30 ish?
[16:37] <craag> LeoBodnar: The air heats up inside the balloon.
[16:37] <Willdude123> mfa298: No time to do that atm.

[16:37] <LeoBodnar> Ballon mass stays the same. Balloon volume stays the same. Why more lift?
[16:37] <G4MYS_Andy> but if it wernt for the chase were about to do Id go take a look myself Andy
[16:37] <m3eav> if you zoom right into purley/kingsley you can see a funny path lines, was that him running aroudn with it screaming when it broke? :-)
[16:37] <M0CJM_Neil> Willdude123 Yeah I am ready but going out at 7:20 downto Overton
[16:38] <SpeedEvil> LeoBodnar: something fell off
[16:38] <LeoBodnar> Considering it is superpressured
[16:38] <Willdude123> I'm going out tonight to, hope it comes near.
[16:38] <craag> LeoBodnar: Balloon volume increases, the balloon stretches further, hence why they often burst at sunrise.
[16:38] <M0CJM_Neil> Going to see a funk band in Overtonwith mate andhave a cople of beers!
[16:39] <G4MYS_Andy> go and ejoy self just mind your hearing!!
[16:39] <M0CJM_Neil> Lol, I plan to :-)
[16:39] <daveake> about to launch #2
[16:39] <m3eav> waayyy
[16:39] <m3eav> go for it
[16:39] <M0CJM_Neil> Yay! Best of luck!
[16:39] <chrisg7ogx> well done dave
[16:39] <G0TDJ_Steve> Good Luck Dave!

[16:40] <GMT> break a cord, I mean leg
[16:40] <m3eav> lol
[16:40] <M0CJM_Neil> What launches we got on tomorrow?
[16:40] <G4MYS_Andy> I wonder which one? and QRG would of been usefull!
[16:41] <daveake> up
[16:41] <G0TDJ_Steve> YAY!
[16:41] <M0CJM_Neil> YAY!!
[16:41] <GMT> oooo!

[16:41] <daveake> yes this time :)
[16:42] <G0TDJ_Steve> Well done Dave
[16:42] <daveake> I need to find a less stressful hobby :)
[16:42] <LeoBodnar> Start chasing
[16:42] <G0TDJ_Steve> Amazing how quick the footprint extends
[16:42] <LeoBodnar> Are you chasing yet?
[16:42] <mfa298> mattbrejza: I did try a tune around but that might have been after you turned it off
[16:42] <mattbrejza> G4MYS_Andy: i turned on one, its on .075
[16:42] <M6KZT> should our yagi be horizontal or verticle or wont it really matter?
[16:42] <eroomde> michael bay preditions as it waits to get a decent ascent rate figure
[16:42] <eroomde> good for a laugh
[16:42] <mattbrejza> this one also has an antenna on it, unlike the first one
[16:42] <eroomde> M6KZT: vertical
[16:42] <eroomde> wants to be same as the transmitting antenna
[16:43] <eroomde> (which is 99% of the time vertical on habs)
[16:43] <M6KZT> we are picking it up now
[16:43] <G4MYS_Andy> stronger sigs on.649 but g have QRM there
[16:43] <eroomde> grats
[16:43] <number10_M0MDB> launch is a bit stressful with people watching and things going wrong daveake , hope this one goes well

[17:04] <Willdude123> Drift happens because the oscillators in the radio modules don't work very well at lowish temperatures.

[17:39] <G0TDJ_Steve> Can't help thinking that WSPR would be an interesting experiment for this.
[17:39] <fsphil> I believe Bill is doing WSPR in the US soon
[17:39] <G0TDJ_Steve> Excellent
[17:40] <fsphil> we could only use it on the excempt frequencies

[17:46] <steve_____> has kingsley stopped transmitting?
[17:46] <G0TDJ_Steve> No, KINGSLEY still on air
[17:46] <LazyLeopard> Been a while since I put the yagi up outside. Should make a bit of difference.

[19:01] <fsphil> Kingsley was predicted to land at 51.0386, -0.681554
[19:01] <edmoore> Which is dave near?
[19:01] <fsphil> near Highstead Lane
[19:01] <fsphil> dave is going for Purley
[19:02] <fsphil> he was just a few km from it on the last update
[19:02] <G7UXW--Kevin> I've made a few observations here in Godalming at on point at the begining I was the only station then as Purley came closer to me decodes became few and far between ,,I'm guessing that the ballon moved more and more into the null of my aerial and then became stronger as purley lowered on hight untill i'm the only one left
[19:02] <fsphil> Kingsley the payload is near a place called Dial Green
[19:03] <mfa298> hopefully he might be getting decodes from purley

[19:21] <fsphil> dave is close enough to not need a yagi
[19:21] <mfa298> we might see the payload move over the fields soon
[19:21] <ibanezmatt13> So from his proximity, I could get that with a magmount?
[19:22] <fsphil> I suspect so yes
[19:22] <fsphil> if the antenna isn't damaged
[19:22] <ibanezmatt13> cool
[19:22] <fsphil> and there's nothing in the way
[19:22] <ibanezmatt13> trees?
[19:22] <fsphil> trees are not too bad
[19:22] <fsphil> for signal
[19:22] <ibanezmatt13> ah right
[19:23] <LazyLeopard> Not so good at letting go of payloads, though.
[19:23] <fsphil> indeed
[19:23] <fsphil> I was still receiving my third payload after it landed in some trees, from about 5km away
[19:23] <mfa298> I got a payload that was on the gruond from further than that with a magmount, but you're a bit reliant on the local geography
[19:24] <fsphil> yea, the last one I did the signal disappeared completely
[19:24] <fsphil> didn't get it again until we where about 500m away
[19:24] <mfa298> I ended up stopping in a few places to get the frequency, then drive in what I hoped was the right direction and see if the signal gets stronger - to the point you can get a decode
[19:25] <mfa298> interestingly the payload I did that landed about 5 miles to the south of purley
[19:26] <ibanezmatt13> just a quick one, with the components I'm using, what type of box would be good? All on one layer, multiple layers? It's just, my Dad and I have two different ideas and both of which are difficult to design. Was looking for a bit of elightenment

[20:01] <ibanezmatt13> Upu, you know the SMA connector on the end of my stripboard? It's always stopping me from designing my box in certain ways because I have to leave room for the coax cable to connect to it.

[20:02] <ibanezmatt13> I may be mistaken, looks like vertical ones don't exist
[20:03] <qyx_> they do
[20:03] <ibanezmatt13> Ideally, either having the connector going up or so the side is far easier for me than having it coming straight out

[20:18] <eroomde> have been out of the loop
[20:18] <ibanezmatt13> mfa298, http://sdrv.ms/1apMsVi there's the issue. Not enough room really for coax
[20:18] <Lunar_Lander> yeah
[20:18] Nick change: number10_M0MDB -> number10
[20:18] <Lunar_Lander> thanks ibanezmatt13 and qyx_ :)
[20:18] <Lunar_Lander> dual core
[20:18] <Lunar_Lander> xD
[20:18] <fsphil> eroomde: nothing yet
[20:19] <ibanezmatt13> I guess it's impossible to something like that with a Pi Lunar_Lander
[20:19] <Lunar_Lander> yea
[20:19] <ibanezmatt13> thought so :)
[20:19] <Lunar_Lander> but as I heard you can have data recording during Radio transmission with interrupts
[20:19] <Lunar_Lander> so maybe you could do it with one chip
[20:20] <Lunar_Lander> and certainly could be done on a real PCB I guess
[20:20] <mfa298> ibanezmatt13: one of those vertical sma sockets might work but you might just need to make the holes a bit bigger - you'de need to find one with a datasheet to get the pin sizes and spacing.
[20:20] <ibanezmatt13> Well, my next step after Pi is Arduino. Followed by the ATMEGA chips on there own
[20:20] <ibanezmatt13> mfa298, you think that's the best option
[20:20] lz1dev (~rgp@46.47.80.192) left irc: Ping timeout: 240 seconds
[20:21] <ibanezmatt13> is there anything I can do to accomate the coax with my current setup?>
[20:21] <mfa298> ibanezmatt13: I've not looked at any data sheets to find out
[20:22] <ibanezmatt13> I was thinking of just going out from the SMA connector I already have straight down through a hole in the box. On that pic, straight down through a hole pretty much next to it. Would that work or is the connector likely to snap off?
[20:22] <mfa298> depends on how much strain is on the connector and board.
[20:22] <mfa298> you can get right angle sma plugs which could help
[20:23] <ibanezmatt13> which way would that point in my case?
[20:23] <ibanezmatt13> upwards or sideways?
[20:24] <mfa298> using your existing socket as it is with a r/a plug
[20:24] <ibanezmatt13> ah right

[21:58] <Upu> yes both recovered ibanezmatt13
[21:59] <Upu> my understanding is the gas cools
[21:59] <ibanezmatt13> excellent
[21:59] <Upu> reduces in volume but if I'm being honest I'm not the expert on this
[21:59] <Upu> seek out Dan-K2VOL
[21:59] <Upu> but book in a few days
[21:59] <Lunar_Lander> OK my question now is the following
[22:00] <Lunar_Lander> if DrLuke is listening that might be good
[22:00] <ibanezmatt13> Where was Kingsley located in the end?
[22:00] <Upu> see spacenear.us
[22:00] <Lunar_Lander> when I integrate the Interrupt pulse counter he wrote for the Geiger Counter into my code, the communication with the GPS seems to break down
[22:00] <Upu> it was on the ground
[22:00] <Upu> missed a tree
[22:00] <Lunar_Lander> the altitude is 0 and not -17 and navmode is 0 and error is 8
[22:00] <LeoBodnar> Well consider a rigid sphere. It does not matter what is the pressure inside as soon as the mass does not change the floating force does not either.
[22:00] <Upu> Lunar_Lander are you using software serial ?
[22:00] <ibanezmatt13> Ah right, good stuff then
[22:00] <Lunar_Lander> no, hardware
[22:01] <Upu> will be something causing the timing to mess up
[22:01] <Lunar_Lander> I have the atmega644 with two UARTS, GPS is on UART o

[22:01] <Upu> I'm not entirely sure Leo but they do tend to drop a little over night
[22:02] <ibanezmatt13> I just need to ask, regarding stability does it matter so much if the heaviest component is not on the bottom and is on the top?

[22:02] <Lunar_Lander> I'd say if you stack something, heavy stuff on top
[22:02] <Lunar_Lander> that could be unstable
[22:03] <LeoBodnar> Upu: how long does you tracker run on a single AAA?

[22:06] <LeoBodnar> UNless one wants to start reducing TX duty ratio from continuous
[22:06] <Upu> I think the step up efficients on the LTC is slightly better than the TPS but really not much in it
[22:07] <Lunar_Lander> ibanezmatt13, had that one with Stormdrifter I also
[22:07] Laurence1 (~laurence@vlsi1.eee.nottingham.ac.uk) joined #highaltitude.
[22:07] <Upu> I was 11db constant using power saving
[22:07] <LeoBodnar> Same here
[22:07] <LeoBodnar> Maybe if tracker sees that it is floating it should cut down tx time
[22:08] <mattbrejza> got the ublox into power save mode? not that youll notice in the freezer
[22:08] <Lunar_Lander> ibanezmatt13, http://s.gullipics.com/image/x/o/r/5yvfhn-ksnsa6-3p75/IMG6561.jpeg
[22:08] <ibanezmatt13> impressive
[22:08] <LeoBodnar> 7 sats in the freezer nps
[22:08] <Upu> your freeze is more GPS friendly than mine
[22:09] <Lunar_Lander> yeah it is a mess
[22:09] <LeoBodnar> Modern junk - plastic everywhere
[22:10] <Upu> Steve got about the same power usage out of a PIC + MAX6
[22:10] <Upu> he was using LTC3506
[22:10] <Lunar_Lander> ibanezmatt13, want to see how I mounted the arduino beneath the sensor board?
[22:10] <ibanezmatt13> Headers?
[22:10] <LeoBodnar> What is the collective thinking on low duty ratio TX regime? To save power AND keep trackers interested
[22:10] <Upu> don't :)
[22:11] <eroomde> usually fldigi misses enough on the tune-in to loose the sentence
[22:11] <LeoBodnar> I am using LTC3526 but they are all pretty much the same efficiency-wise
[22:11] <eroomde> and it's not that interesting

[22:11] <LeoBodnar> I have GPS discipline TCXO
[22:12] <LeoBodnar> And with Domino +-200Hz offset is OK
[22:12] <LeoBodnar> *d
[22:12] <Upu> Well I've just knocked up a PCB for the LMT2 with a 16 bit DAC
[22:12] <Upu> which should easily be able to do any of the modes
[22:13] <ibanezmatt13> Lunar_Lander: nice

[22:13] <Lunar_Lander> it held
[22:13] <Lunar_Lander> xD
[22:13] <LeoBodnar> So 10 min each hour? 1min each 5 minutes?
[22:13] <ibanezmatt13> got to go now, thanks for the pics :) Good night

[22:13] <Lunar_Lander> good night ibanezmatt13
[22:13] <ibanezmatt13> night :)

[22:15] <LeoBodnar> Maybe during the night trackers can leave RX on?
[22:15] <Upu> My theory on extreme power saving
[22:15] <Upu> fit a fet and turn the GPS off entirely (link battery to vbackup)
[22:15] <Upu> fit an accelerometer
[22:16] <Upu> dead reckon
[22:16] <Upu> correct every 30 mins
[22:16] <Upu> or whatever with the GPS
[22:16] <LeoBodnar> Yes, they suggest this in the DS. Bizarre to see that suggested. I would have assumed the should have provided SW only way.
[22:16] <craag> +1 for that
[22:16] <fsphil> if the payload has detected it's on the ground, store the position in the EPROM
[22:16] <fsphil> won't need the GPS again
[22:17] <Lunar_Lander> yea
[22:17] <LeoBodnar> What's the point in keeping TX running all this time?
[22:17] <Lunar_Lander> just the voltage for using the EEPROM
[22:17] <fsphil> assuming it's past a few tests, like has it a valid lock
[22:17] <Lunar_Lander> carrier signal can be used for ranging
[22:17] <Upu> so you know its alive :)
[22:17] <craag> Until we have some reliable, wide autotune, you shouldn't switch the TX off.
[22:17] <Upu> but really
[22:17] <craag> That as well.
[22:17] <LeoBodnar> Switch into stationary mode :)
[22:17] <Upu> here is the issue
[22:17] <LeoBodnar> Collect and average samples, then turn GPS off
[22:17] <Upu> you can't keep a balloon up longer than your payload can run for
[22:17] <Upu> try it :)
[22:18] <LeoBodnar> Send CW id every 30 seconds.
[22:18] <craag> And if you find a lighter cell than a Lithium AAA that can provide GPS acquisition current, I'd be very interested!
[22:19] WILLdude (~george1@wikipedia/W-D) left irc: Ping timeout: 248 seconds
[22:19] <Upu> btw Leo I may have to run my new payload at 2.2v
[22:19] <craag> Lithium AAA is the smallest cell around, and it'll do a couple of days with upu's payloads iirc.
[22:19] <Upu> I can't find a 1.8V TCXO
[22:19] <Upu> that isn't £50
[22:20] <Upu> Got one that runs @ 2.2V and is £5 MOQ 5
[22:21] <LeoBodnar> Mine IS 2.2V lol. Forgot to turn Vddcore off. But next one is 2.0V

[22:22] <Upu> 30Mhz small as
[22:22] <Upu> not going to bother with Domino with this board
[22:22] <LeoBodnar> Surely not 2.0x1.4mm? XD
[22:22] <Upu> whatever :)
[22:23] <Upu> maybe a little larger
[22:23] <Upu> no oven :)
[22:23] <Upu> stability to -30
[22:23] <LeoBodnar> Then 3.2x2.5 is probably best

[22:23] <Upu> yeha
[22:24] <LeoBodnar> I'll have a look as well. Are you OK with 26..32MHz range? This is specced range for Si4460s
[22:24] <Upu> yup

[22:27] <LeoBodnar> I'm on it. I have killed whole two days trying to find mine.
[22:27] <Upu> Golledge are usually quite good for crystals and SAW filters
[22:27] <LeoBodnar> These are MOQ parts aren't they?
[22:28] <Upu> yeah but usually single digits
[22:28] <Upu> that one is 5
[22:28] <Upu> 5 @ £5 per 4 week lead
[22:29] <Adam012> Good night all! Early start tomorrow.
[22:29] <Upu> 50 is 1.95
[22:29] <Upu> night Adam012
[22:29] <LeoBodnar> Wait, found something

[22:34] <Upu> hmm how did I miss that
[22:34] <Upu> ah yes US order charge I generally ignore parts with that on
[22:35] <LeoBodnar> I do too but not when I am desperate XD
[22:35] <Upu> how many do you want ?
[22:35] <eroomde> 'in stock' 'exclude extended range'
[22:35] <eroomde> it's a relex to tick those boxes on farnell searches for me
[22:35] <eroomde> reflex*
[22:36] <LeoBodnar> eroomde: yes, automatic
[22:37] <LeoBodnar> I have ordered same TCXO but with funny freq for domino experiments - it's outside DS spec.
[22:37] <Upu> ok
[22:38] <LeoBodnar> They shipped this week. Should have waited for you XD
