[14:12] <m1x10> i took a vid of her dying but later i deleted it. I couldnt watch it
[14:12] <fsphil> understandable
[14:12] <fsphil> are there many snakes there?

[14:18] <fsphil> there are no snakes here at all, thankfully

[16:02] <NigeyS> yikes
[16:02] <SpeedEvil> There is a new method of soldering - that's gentler and more organic. I keep meaning to try it.
[16:02] <SpeedEvil> It's known as 'cod heat'.
[16:03] <Lunar_Lander> yes?
[16:03] <Lunar_Lander> NigeyS then I tried the light sensor

[16:06] mazzanet (~mazzanet@hpavc/mazzanet) left irc: Ping timeout: 260 seconds
[16:06] <Lunar_Lander> so I hope that this one works
[16:07] <Lunar_Lander> I think that this cheap soldering iron is too weak
[16:07] mazzanet (~mazzanet@hpavc/mazzanet) joined #highaltitude.
[16:07] <Lunar_Lander> after swiping I held the solder to it to solder the tip
[16:07] <Lunar_Lander> and it didn't melt the solder until after about half a minute
[16:08] <SpeedEvil> Is the soldering iron tip bright?
[16:08] <Lunar_Lander> it looks matt
[16:08] <BrainDamage> it shouldn't glow though :p
[16:08] <Lunar_Lander> yea
[16:08] <SpeedEvil> Shiny, I mean.
[16:08] <Lunar_Lander> no, it looks dull
[16:08] <Lunar_Lander> that describes it I think
[16:09] <BrainDamage> it should have a thin layer of solder on it
[16:09] <Lunar_Lander> yeah I did that on the light sensor
[16:09] <BrainDamage> no, the soldering iron
[16:09] <Laurenceb> can anyone suggest how i could create a simlink to a text file
[16:09] <BrainDamage> it will protect the tip, conduct the heat better, and help getting the solder molten
[16:10] <Laurenceb> and get a program running under wine to chuck data to the file?
[16:10] <SpeedEvil> umm - ln -s?
[16:10] <Laurenceb> atm its not connecting
[16:10] <Lunar_Lander> I meant I applied solder to the iron on the light sensor attempt BrainDamage
[16:10] <Laurenceb> it only connects to a real serial port
[16:10] <Laurenceb> i dont see why
[16:10] <SpeedEvil> Lunar_Lander: the problem is that the soldering iron is not tinned - so it has sucky connectivity.
[16:10] <NigeyS> Researchers have set a new record for the rate of data transfer using a single laser: 26 terabits per second.
[16:10] <Lunar_Lander> yea
[16:10] <NigeyS> bloody nora
[16:10] <Lunar_Lander> and I think it is too weak too?
[16:11] <Lunar_Lander> because it took loads of time to melt the solder for tinning
[16:11] <BrainDamage> how much power?
[16:11] <SpeedEvil> Lunar_Lander: The soldering iron tinning is what conducts the heat properly.
[16:11] <Lunar_Lander> yea
[16:11] <SpeedEvil> Without it, it's _way_ less.
[16:11] <Lunar_Lander> and thus it took so long for the solder to melt and so on?
[16:11] <SpeedEvil> Get some old denim, or similar, wet it, and try rubbing the iron on it while hot, then immediately tinning.
[16:12] <Lunar_Lander> ah
[16:12] <Lunar_Lander> if that doesn't work, I could ask my father if I could use his old Weller iron
[16:12] <SpeedEvil> If this doesn't help - let it cool down, and scrub at the black bit with a kitchen scoury sponge until it's at least got bits of metal in.
[16:12] <Lunar_Lander> ok
[16:12] <SpeedEvil> Then repeat the damp denim/... and tinning.
[16:12] <Lunar_Lander> yea
[16:13] <SpeedEvil> you can also get little 'tinning blocks'
[16:13] <Lunar_Lander> denim is like jeans stuff right?
[16:13] <griffonbot> Received email: Dan Bowen "Re: [UKHAS] UK Balloon Flight Guidelines"
[16:13] <BrainDamage> the fast you'll tin, the better will be, because you'll be racing with oxide formation
[16:13] <SpeedEvil> which are lightly abrasive mixtures of flux and solder.
[16:13] <SpeedEvil> yes.
[16:13] Action: Laurenceb nickserve identify compost
[16:13] <Lunar_Lander> yeah
[16:13] <Laurenceb> shit
[16:13] <Lunar_Lander> and as I said
[16:13] <Lunar_Lander> when I swiped the iron and then tried to tin it
[16:13] <BrainDamage> there's also salt ammoniac ( amonium chloride ) tip refreshners, which are a mixture of tin and that
[16:13] <griffonbot> Received email: Martin 100 "[UKHAS] Re: UK Balloon Flight Guidelines"
[16:13] <Lunar_Lander> it took quite long for the solder to melt on the tip
[16:13] <SpeedEvil> Every time you put down the iron - wipe the tip, and tin it a little bit.
[16:13] <Lunar_Lander> yeah
[16:13] <BrainDamage> they are rather powerful though
[16:14] <Lunar_Lander> thanks for the info!
[16:14] <Lunar_Lander> :)
[16:14] <Lunar_Lander> SpeedEvil also when I got several headers or so, swipe and tin for every header or just when I put the iron away?
[16:15] <BrainDamage> tip the tip before and after every usage, once it's tinned properly, a simple wet sponge to clean should suffice
[16:15] <BrainDamage> tin the tip*
[16:16] <Lunar_Lander> ok
[16:16] <Dan-K2VOL> Also brass coil sponge will make your tip last longer than the wet sponge
[16:16] <BrainDamage> it should be unnecessary for every single component
[16:16] <BrainDamage> careful with the brass shavings because they tend to fling molten solder
[16:16] <SpeedEvil> yeah you only need to refresh it if it's been sitting for a minute or more hot.
[16:17] <Dan-K2VOL> As it does not cool the metal as much, and doesn't introduce water, which accelerates oxidation of the tip
[16:17] <Lunar_Lander> yea
[16:17] <Dan-K2VOL> braindamage it does less of that if you insert the tip straight in and out, and don't drag it along the top
[16:18] <BrainDamage> Dan-K2VOL: I know how to use it, but he won't the firt time he does, so better warn him beforehand :p
[16:18] <Dan-K2VOL> oh yes good plan

[16:25] <NigeyS> soo... all in favour of self regulation say aye :|
[16:27] <Dan-K2VOL> wellllll I think that govt regulation needs to be changed, as has been demonstrated on this chat room that there are certain maverick personalities that will refuse to abide by gentleman's agreements
[16:28] <Dan-K2VOL> meaning rules made by advisory clubs/groups/organizations
[16:29] <Dan-K2VOL> I'm going to make the effort to change the US rules
[16:29] <russss> what changes do you want, Dan-K2VOL?
[16:29] <Dan-K2VOL> I have no idea if I have the money and time to accomplish it, but hopefully I'll pick up help along the way
[16:29] <russss> better rules for long-duration flights?
[16:29] <Dan-K2VOL> Yes
[16:29] <Dan-K2VOL> Precisely
[16:30] <NigeyS> i quite agree with the pint already made .. this has been looked at by the CAA and if they thought these launches were a severe risk, then the rules would be enforced, and or set in place
[16:30] <NigeyS> point*
[16:30] <Dan-K2VOL> Here we could launch 11.9 lb white star speedball payloads every hour for a year and not have to notify the FAA
[16:30] <russss> yeah, I think lobbying the government for *more* regulation is a bad thing :)
[16:31] <russss> I don't think we've really seen people doing stupid stuff in the UK, have we?
[16:31] <NigeyS> not that i know of
[16:31] m1x10 (m1x10@ppp091138213226.dsl.hol.gr) joined #highaltitude.
[16:31] <Dan-K2VOL> russss the problem is that it's going to change, as these get more popular (and they clearly are, fast) someone will realize that the rules are not what the safety-fearing media would want
[16:31] <russss> the other thing is that if UKHAS has a system of voluntary regulation then perhaps it might be easier to get insurance
[16:31] <jonsowman> well I think there have been some issues with UK flights
[16:31] <Dan-K2VOL> I'd rather change them now to something that's reasonable
[16:31] <jonsowman> including passing through existing NOTAMs
[16:31] <NigeyS> i thin if we start asking for some official rules, we end up with a scenario where those rules can be changed and altered and extended to such a point launches become impossible.
[16:31] <Dan-K2VOL> Than have them banned altogether by a soccer-mom led mob
[16:32] <Dan-K2VOL> NigeyS, I can't speak on the subject of lawmaking in the UK, I'm sadly unfamiliar with the parliamentary process there.
[16:33] <jonsowman> I think the idea is to come up with a collective set of rules that if we abide by and can prove work, then when/if the time comes where the CAA decides more regulation is required, they will use our rules since they've been proven and people are using them anyway
[16:33] <jonsowman> it depends largely on why the CAA chose to increase regulation
[16:33] <russss> well, the rules are not defined by parliament
[16:33] <jonsowman> if that ever happens
[16:33] <Dan-K2VOL> But here, you don't want to go asking for more rules. You get a congressman to go the agency with a proposed change to the rules, all neatly typed up
[16:33] <Dan-K2VOL> So they just have to put it up for comment and a yes/no vote
[16:33] <russss> they are basically tertiary legislation defined by the CAA
[16:34] <jonsowman> I guess the "ruleset" would be implemented as terms in the notice of variation for the launch from the CAA
[16:34] <russss> yeah
[16:34] <Dan-K2VOL> I think that a voluntary ruleset would be a great start
[16:34] <Dan-K2VOL> And fly for a few years proving they allow safe operations
[16:35] <jonsowman> I think that's the main idea
[16:35] <Dan-K2VOL> Then you could suggest those as the template for rules to be adopted
[16:35] <jonsowman> indeed
[16:35] <Dan-K2VOL> If you wanted to
[16:35] <jonsowman> I think it's a good idea to have a set of guidelines to give new hobbyists somewhere to start
[16:35] <Dan-K2VOL> That's how the US ARRL and US AOPA (Aircraft owners and pilot's association) have made changes happen several times
[16:36] <jonsowman> it would only require a couple of people to do stupid things before the CAA have to get involved
[16:36] <jonsowman> I've known at least two launches in the UK done without NOTAMs
[16:36] <Dan-K2VOL> The model rocketry hobby has this well done I think
[16:36] <jonsowman> I think it's a step in the right direction for both those reasons
[16:37] <Dan-K2VOL> Yeah
[16:38] <NigeyS> dont we then run the risk of a scenario where, for instance, a habber follows our "voluntary" rules, something goes wrong, and ukhas then gets the blame?
[16:38] <Dan-K2VOL> Btw NOTAMs seem to be much less binding in the US, they're simply advisory notices to airmen that we can opt to generate, or not. Most US flights do not take the trouble to call in and generate one
[16:38] <jonsowman> NigeyS: we need to make it clear that they are only guidelines
[16:38] <jonsowman> and that they provide no legal protection
[16:39] <jonsowman> however just because they're "best practise" rather than law, it doesn't make them worthless
[16:39] <Dan-K2VOL> I think lawyers would need to review it to make sure of that sort of thing
[16:39] <russss> you americans and your lawyers
[16:39] <NigeyS> agreed, as i think if not, 1 major incident, would tarnish the entire ukhas group / name etc and things then get very messy indeed
[16:39] <russss> :P
[16:39] <russss> 1 major incident would tarnish the whole hobby
[16:40] <russss> the fact of the matter is that a major incident is extremely unlikely
[16:40] <NigeyS> that aswell, but if someone in their defence says "oh but i followed the ukhas guidelines" ..
[16:41] <russss> well, that's also why it might be useful to build on the ICAO rules.
[16:41] <jonsowman> providing advice doesn't mean someone can fall back on it legally I don't think
[16:41] <jonsowman> not when provided as "here's what we think you should do, but it's your choice"
[16:41] <russss> also, there's clear evidence of good faith there,.
[16:41] <russss> (also, UKHAS *already* provides advice)
[16:41] <jonsowman> indeed
[16:41] <NigeyS> true, either way i'm glad james has opened this up for discussion
[16:41] <russss> that's the whole point!
[16:42] <BrainDamage> also, even following your guidelines doesn't mean you should consider every single common sense mishap
[16:42] <BrainDamage> like "do not stop the chainsaw with your genitals"
[16:42] <LazyLeopard> ...then at least the court is going to go and read said guidelines, to see whether the culprit did in fact do so.
[16:42] <jonsowman> I think overall we're reducing the risks here, which can only be a good thing
[16:42] <LazyLeopard> Yep.
[16:42] <russss> yeah, you can always argue that without the UKHAS guidelines it could well have been worse.

[16:44] <jonsowman> NigeyS: do you mean 14th?
[16:44] <NigeyS> it'll be a fully inflated 4 x 36" launch to get some burst / pressure data for Steve
[16:44] <russss> UKRA would be the obvious thing to look at as an example, of course. In general rockets are a lot more dangerous than balloons
[16:44] <jonsowman> oh, this isn't the cambridge one?
[16:44] <NigeyS> no the 4th .. this is the foil launch not the ats-1 latex launch hehe
[16:44] <jonsowman> phew

[18:27] GeekShadow (~Antoine@reactos/tester/GeekShadow) left irc: Ping timeout: 276 seconds
[18:27] <BrainDamage> yeah, the tip stores temp ( heat capacity ), when touching something you draw it away in heat form
[18:27] <BrainDamage> the resistive element tries to replenish
[18:28] <BrainDamage> but having a large reservoir helps
[18:28] <BrainDamage> as well as having a temp controlled iron, but that's not necessary
[18:29] <Dan-K2VOL> a temp controlled iron simply allows you to use it on a wider range of sized joints, replenishing heat on demand, as opposed to continuous heat
[18:30] <BrainDamage> yes, also allows higher power without having higher temp
[18:31] <BrainDamage> mm, I guess I should phrase it as, what you said is the conseguence of my previous sentence >_>
[18:31] RocketBoy (~steverand@ left irc: Quit: RocketBoy
[18:33] <Dan-K2VOL> Heh
[18:34] <Dan-K2VOL> Yeah, nice, but not necessary
[18:35] <Dan-K2VOL> One irritating situation I've found with soldering is when a pad is connected to a ground plane without thermal gaps around it. That takes an extraordinary amount of heat to solder
[18:36] <Dan-K2VOL> A hot air gun preheating the ground plane helps there

[18:52] <fsphil> had a very quick scan through that pdf, may have missed it, but what modulation style does ADS-B use? (FSK, AFSK?)
[18:52] <BrainDamage> what does afsk stand for?
[18:52] <fsphil> audio frequency shift keying
[18:53] <Elwell> http://adsb.tc.faa.gov/WG5_Meetings/Changes/UAT-App_C.pdf
[18:53] <Dan-K2VOL> Fsphil I'm not sure
[18:54] <fsphil> just wondering if something like the NTX2 could do it
[18:54] <fsphil> if it's just AFSK it would be very simple
[18:54] <mattltm> what about freq drift?
[18:54] <fsphil> not so bad for a plain FM signal
[18:55] <fsphil> receiver should still lock onto it
[18:55] <Dan-K2VOL> Elwell, nice doc find on the encoding protocol
[18:56] <fsphil> ooh nice
[18:56] <Elwell> dan google 'ads-b encoding' about 1/2 way down 1st page
[18:56] <Dan-K2VOL> you guys in the UK are in the prime spot to pioneer this stuff, we have really lagged behind in implementing ADS-B
[18:56] <SpeedEvil> ads-b?/
[18:56] <Elwell> SpeedEvil: http://en.wikipedia.org/wiki/Automatic_dependent_surveillance-broadcast
[18:56] <Dan-K2VOL> well, any of you guys in Europe are in a good spot for ADS-B ground station implementation
[18:56] <SpeedEvil> ah
[18:57] Action: Elwell should have a play seeing as he's not far off the approach line for GVA
[18:58] <fsphil> it's up in the ghz frequencies isn't it?
[18:58] <Elwell> I'd like to get one of those transponder-reciever boxes, but too dear just now
[18:58] <fsphil> could probably receive it with the funcube dongle
[18:58] <Elwell> that did occour to me :-)
[18:58] <fsphil> aah, 1080 mhz
[18:58] <mattltm> nice reciver.... http://www.lll.lu/~edward/edward/adsb/Very Simple ADSB receiver.html
[18:58] <Elwell> just. think it (fcd) goes to 2.1?
[18:59] <fsphil> it can do 2.something ghz but I don't think it works very well up that high
[18:59] <BrainDamage> actually, that link's name suggested me something else at first, which much be a future thing: using commercial flights as spy planes/ground radars for traffic monitoring, surveillance, etc :p
[19:01] <fsphil> http://www.avionik.pl/pliki/ADS-B-dane-techniczne.pdf
[19:01] <Dan-K2VOL> Looks like it's just On-Off keying!
[19:01] <Lunar_Lander> hey sorry Dan-K2VOL thanks!
[19:02] <Dan-K2VOL> Lunar_lander, np I figured you were away
[19:02] <Lunar_Lander> :)
[19:02] <Lunar_Lander> I'll brb
[19:03] <fsphil> "The modulation used is PPM"
[19:03] <Dan-K2VOL> well, I don't know if it's wise, but it looks very easy to build
[19:03] <Dan-K2VOL> https://trainingzone.eurocontrol.int/ATMTraining/PreCourse/SUR/ADS/Taste%20the%20Course/32501.10.32657.85.28722/Default.html a nice visual of the pulsetrain
[19:03] <fsphil> bandwidth seems very wide, the funcube dongle is not going to receive it
[19:04] <Dan-K2VOL> for simple pulsed carrier wouldn't any bandwidth pick it up? (i'm not that great at RF, so I'm not sure)
[19:05] <fsphil> could hear it, but I don't think it would decode anything meaningful
[19:05] <fsphil> funcube dongle has about 80khz, the documents I've seen talk about mhz
[19:07] <Dan-K2VOL> I'm not sure why it wouldn't decode it, it's like morse code in that it turns the transmitter off for 0s and on for 1s, so if you hear any signal, it should be interpreted as a 1
[19:09] <fsphil> my basic understanding is that the bandwidth is the bitrate * 2
[19:09] <fsphil> so 500bit/s would need 1000hz bandwidth
[19:09] <fsphil> I can't find a bitrate anywhere for this
[19:09] <SpeedEvil> Sort-of.
[19:09] <fsphil> there's always a sort-of :)
[19:09] <Dan-K2VOL> Ah
[19:10] <SpeedEvil> Bandwidth is bitrate*2 only for rs232 and stuff.
[19:10] <SpeedEvil> Ish.
[19:10] <SpeedEvil> If you use multi-level signaling, it can go lots lower.
[19:10] <SpeedEvil> In short - you trade of signal-noise for bandwidth.
[19:10] <SpeedEvil> If you have 256 symbols per period - then you get 8 times the throughput, but a fair bit less noise immunity.
[19:10] <Lunar_Lander> back
[19:11] <fsphil> true
[19:11] <fsphil> for this it seems to be 1-bit per symbol
[19:11] <Lunar_Lander> hi mattltm
[19:11] <mattltm> Hi Lunar_Lander
[19:12] <Lunar_Lander> Dan-K2VOL the best thing was the response at sparkfun
[19:12] <Lunar_Lander> "I haven't soldered since 2002 but I never soldered this bad"
[19:12] <fsphil> lol
[19:13] <Dan-K2VOL> Haha kevin
[19:13] <Dan-K2VOL> Ok according to this: http://www.tech-software.net/adsb_decode1.php
[19:14] <Dan-K2VOL> it looks like the minimum symbol width is 0.5 us
[19:14] <Dan-K2VOL> So that's 2MHz rate
[19:15] <fsphil> impossible for the funcube, but forgetting that it's a really simple modulation so could be done with very simple circuits
[19:15] <Lunar_Lander> btw
[19:15] <Lunar_Lander> someone just said that I could try to remove the pins
[19:15] <Lunar_Lander> how?
[19:15] <Lunar_Lander> with the desoldering band?
[19:16] <Dan-K2VOL> I haven't seen pics, can you post link
[19:16] <Dan-K2VOL> Lunar_lander
[19:17] <Lunar_Lander> one moment
[19:18] <Dan-K2VOL> Looks like the data rate is 1Mbps, but it's like manchester encoding, so the width of the smallest signal is half that
[19:19] <Lunar_Lander> Dan-K2VOL

[19:21] <Dan-K2VOL> Oh just have someone else help you with needle nose pliers to push the pins individually to their proper depth
[19:21] <Dan-K2VOL> While you have the soldering iron on the joint of that pin
[19:22] <Dan-K2VOL> Brad and I have taken out entire 44 pin connectors pin by pin that way
[19:22] <Dan-K2VOL> But it really takes a second person to not be a royal pain in tha ss
[19:22] <Lunar_Lander> ah
[19:22] <Lunar_Lander> yeah I noticed that
[19:22] <Dan-K2VOL> Heh
[19:22] <Lunar_Lander> also I did the following mistake
[19:22] <Lunar_Lander> I broke off all the pins
[19:22] <Lunar_Lander> I should have broken off a row of six
[19:23] <Dan-K2VOL> oh so you've got 6 indiviudal pins
[19:23] <Lunar_Lander> yes
[19:23] <Dan-K2VOL> That's ok, again, just adjust their depth manually like I described
[19:23] <Lunar_Lander> yea
[19:23] <Dan-K2VOL> and really just pry off all that plastic
[19:23] <Lunar_Lander> ah
[19:23] <Dan-K2VOL> It's only job was to help you hold them steady for soldering
[19:23] <Lunar_Lander> if I can get this one pin down...
[19:23] <Lunar_Lander> I mean I just put the thing into my breadboard
[19:23] <Lunar_Lander> it actually fits in
[19:24] <Lunar_Lander> save for that one pin which doesn't make contact of course
[19:24] <Dan-K2VOL> Well, you could just press down on the table while heating the joint
[19:24] <Lunar_Lander> yea!
[19:24] <Lunar_Lander> thanks :)
[19:24] <Dan-K2VOL> :-) anytime, wish i could actually lend a hand
[19:24] <Lunar_Lander> yeah
[19:24] <Lunar_Lander> a friend of mine actually suggested me working with Skype on
[19:24] <Lunar_Lander> so that one of you could supervise me working
[19:24] <Dan-K2VOL> Looks like arduino has no problem changing pins at 2MHz rates when using optimized digitalWrite
[19:25] <Dan-K2VOL> Oh good idea, i'd be willing to! but the hours would be rough
[19:25] <Lunar_Lander> yea
[19:25] <Lunar_Lander> np :)
[19:25] <Lunar_Lander> btw my dad said that I could borrow his old Weller iron
[19:26] <Dan-K2VOL> That's nice of him
[19:26] <Lunar_Lander> yea
[19:26] <Dan-K2VOL> What iron do you have now
[19:26] <Lunar_Lander> well
[19:26] <Lunar_Lander> there once was that magazine called "Real Robots" and when you subscribed they gave you a little toolbag with two magnetic screwdrivers, pliers, soldering iron and solder pump
[19:27] <Lunar_Lander> and the iron has no brand
[19:27] <Lunar_Lander> and when it heated it actually smoked from the back, so I think that it is not really good
[19:28] <BrainDamage> Lunar_Lander: http://store.curiousinventor.com/guides/How_To_Solder/
[19:28] <BrainDamage> that guide is really well made, check it out
