[00:15] <NigeyS> i'm good now, caught up on my sleep i lost over the weekend !
[00:19] <natrium42> excellent :)

[00:21] <NigeyS> wee
[00:21] <NigeyS> another step closer to completion
[00:22] <natrium42> what sensors are you gonna fly?
[00:23] <NigeyS> for ats-1 i just have 2 temp sensors, first play is more of a "get some experience" flight
[00:24] <NigeyS> play? .. duh .. flight*
[00:24] <natrium42> sensible
[00:24] <natrium42> hehe
[00:24] <NigeyS> it's been a hard slog for a total n00b to even get this far, guys in here have been a god send
[00:25] <NigeyS> and no its not flying on a breadboard .. stripboard FTW !
[00:25] <natrium42> :D
[00:26] <NigeyS> thinking how to grab the gps lat & long to send the sms data
[00:26] <NigeyS> my limited lack of C says create some kind of buffer and send it from there rather than have 2 nss objects open for any length of time

[08:00] <eroomde> morning all
[08:01] <eroomde> jgrahamc: I enjoyed your write-up -- thank you for the nod!
[08:01] <jgrahamc> You deserve eroomde!
[08:01] <jgrahamc> Whoops missed the it
[08:01] <jgrahamc> You deserved it eroomde! :-)
[08:02] <eroomde> I don't need much encouragement to spend a sunny sunday morning ballooning
[08:11] <griffonbot> @apexhab: Footage from Apex II's second launch now available to view! http://j.mp/hGV1XV #apexhab #ukhas [http://twitter.com/apexhab/status/57717443606495232]
[08:11] <priyesh> Hi all! Footage from Apex's launch the other day now ready: http://vimeo.com/22262445
[08:12] <eroomde> too slow
[08:12] <eroomde> griffonbot is the sharpest shooter in the west
[08:12] <jonsowman> haha
[08:12] <jonsowman> morning eroomde
[08:13] <eroomde> good morning
[08:15] <eroomde> jgrahamc: I like the aerial shot of the dome
[08:16] <jgrahamc> I hadn't spotted the dome. Nice. Also, I'm pretty sure that on the right in that photo there's a large horizontal straight area which must be LHR.
[08:17] <jgrahamc> BTW eroomde The people we were going to meet after we left you were Henry Hurst and his family. He told me that the Master of Churchill thinks the world of CUSF
[08:19] <eroomde> oh right!
[08:20] <eroomde> Yes since we did the Teddies in Space project he's always shown a lot of enthusiasm
[08:20] <jonsowman> excellent writeup jgrahamc :)
[08:20] <jgrahamc> Hurst wanted me to do a GAGA-2 and ensure that it landed in his back garden (to be fair he has 16 acres of land)
[08:20] <eroomde> and a personal interest - which is I think sometimes unusual for masters of colleges
[08:20] <jgrahamc> Thanks jonsowman
[08:21] <jgrahamc> The Principal of my college on Oxford told me that he would only ever invite one mathematician at a time for dinner in his lodgings.
[08:21] <eroomde> :)
[08:22] <jgrahamc> What do you guys think about the temperatures I saw. The minimum external was -20C (roughly in the tropopause). Then it rose a lot. I'm wondering if the top mounted sensor simply heated up in the sun.
[08:23] <jgrahamc> At the peak of the flight I was measuring 9C externally.
[08:24] <eroomde> 9 degrees is certainly quite warm for ambient temperature - I suspect you're right that it was radiatively heated
[08:24] <eroomde> ha, just found this on a dark corner of our site: http://www.srcf.ucam.org/~cuspaceflight/images/stripped_down_cam.jpg
[08:24] <eroomde> this was the A540 I got down from 210g to 62g
[08:24] <jgrahamc> Whoa!
[08:25] <eroomde> it still worked, but it was quite hairy surgery
[08:26] <eroomde> I think we used it in a micro payload but I gorget which. We should have documented our early days a little more thoroughly

[08:54] <jonsowman> recommendations on chutes?
[08:56] <griffonbot> Received email: andrewallan "[UKHAS] Thanks for listening."
[09:01] <eroomde> jonsowman: design or seller?
[09:01] <jonsowman> both really. the Apex II chute is just not good enough, looking for a replacement
[09:02] <eroomde> cruciforms are stable and good
[09:02] <eroomde> disk-gap-band or ring-slot are also stable
[09:02] <eroomde> whatever you do don't use flat sheets
[09:02] <eroomde> they're just a bunch of crap
[09:03] <eroomde> aeroconn systems is good for random small parachutes
[09:03] <eroomde> spherchutes make hemispherical parachutes - not the most stable but better than sheets and they are well constructed
[09:03] <eroomde> our organe ones are really stable but heavy for the drag
[09:03] <eroomde> orange*
[09:03] <jonsowman> yeah I was looking at spherachutes
[09:04] <eroomde> I personally like them a lot
[09:04] <eroomde> the orange ones, that is
[09:04] <jonsowman> there's a really nice one in the CUSF lab, ~4ft diameter, white, no markings
[09:04] smea (~smealum@82.243.132.64) joined #highaltitude.
[09:05] <eroomde> yes we've flown that a few times
[09:05] <eroomde> that's a hemi
[09:05] X-Scale (email@2001:470:1f14:135b::2) joined #highaltitude.
[09:05] <jonsowman> spherachute? or just a random hemi?
[09:05] <eroomde> I think Nova 9 (teddies) to nova 12 flew with that
[09:05] <eroomde> this one I beleive http://aeroconsystems.com/cart/products/60_inch_white_parachute-68-65.html
[09:06] <NigelMoby> Morning all
[09:06] <jonsowman> yeah ~1.5m is required, that looks good
[09:06] <eroomde> but as I say, these ones get my money: http://aeroconsystems.com/cart/products/72_inch_orange_parachute-70-65.html
[09:06] <eroomde> just beutiful
[09:06] <eroomde> and bright as anything in a field
[09:07] <NigelMoby> Try a X-form chute Jon?
[09:07] <jonsowman> that is nice
[09:07] <eroomde> we saw it come down on Nova 17 - it stuck out like a sore thumb in the sky
[09:07] <jonsowman> a lot of the Apex kids really want to see one come down
[09:07] <eroomde> http://aeroconsystems.com/cart/images/products/secondary/12.jpg
[09:07] <eroomde> yummy !
[09:07] <jonsowman> bright orange chute = good in that sense
[09:08] <eroomde> it weighs about 1.5kg though, that's the only thing
[09:08] <eroomde> however high mass and lots of helium seems to be an apex trademark :p
[09:08] <jonsowman> gosh
[09:08] <jonsowman> haha, yes indeed
[09:08] <eroomde> and the 1.5kg is not 'dangerous' weight - it's a soft parachute
[09:08] <jonsowman> pretty complex payload
[09:09] <fsphil> I like the bright payload -- I'm thinking my silver box might not be the most visible on the ground,
[09:09] <eroomde> yeah, go for really lurid day-glow paints
[09:09] <jonsowman> our main issue is that the school has to plan things way in advance, and we often end up overfilling to get around less-than-ideal flight paths
[09:10] <eroomde> silvery shiny things help too
[09:10] <eroomde> especially ticker-tape type stuff which flutters in the breeze
[09:11] SpikeUK (d0331fa2@pdpc/supporter/monthlybyte/spikeuk) left irc: Quit: Page closed
[09:11] <eroomde> i am also going to replace the line to the parachute with a ~15cm wide ribbon of bright orange parachute nylon (with edges re-infoced with kevlar or something) as when payloads land in crop field they often sink below the 'canopy' of the crops, so you can't see them. 10m or so of this ribbon should hopefully rest on the top
[09:12] <jonsowman> that's a good idea

[09:13] <eroomde> aeroconn systems really is a sweetie shop for aerospace hobbyists
[09:14] <jonsowman> yeah I'm looking through it at the moment
[09:14] <jonsowman> lots of nice stuff
[09:14] <NigelMoby> Fluorescent pink paint you need Phil :p
[09:15] <eroomde> he's right y'know ^
[09:16] <jgrahamc> Fluorescent paint saved us a lot of messing around on Sunday.
[09:19] <NigelMoby> I bet
[09:29] <jonsowman> eroomde: those aeroconn chutes have attachment points on their apex don't they?
[09:32] <NigelMoby> Jgrahamc, http://www.youtube.com/watch?v=DNBVF4A28-E&feature=youtube_gdata_player
[09:33] <jgrahamc> That's the ticket
[09:33] <NigelMoby> Odd url .. hmm
[09:37] <eroomde> jonsowman: whoch ones - the orange oens?
[09:37] <jonsowman> yep
[09:37] <eroomde> yes they do
[09:37] <jonsowman> cool thought so, bit hard to see in the pictures
[09:37] <jonsowman> ta
[09:38] <eroomde> if anyone finds a source of *locking* mini aluminium caribinas please say so too
[09:38] <eroomde> I want to buy a bunch
[09:40] <jonsowman> eroomde: how small do you wnat?
[09:41] <jonsowman> I got a few off amazon a while back
[09:42] <eroomde> like 5g
[09:42] <jonsowman> oh okay, they're not that small
[09:43] <eroomde> it'd be for the balloon neck flight computer
[09:43] <eroomde> to attach whatever people want to dange underneath
[09:43] <NigelMoby> I might have some
[09:43] <jonsowman> oh yes, how's that flight computer going?
[09:44] <eroomde> totally stagnant
[09:44] <eroomde> but now that the airship stuff is out the way...
[09:44] <NigelMoby> If not there some 6g ones on amazon ed
[09:44] <jonsowman> :)
[09:45] <eroomde> NigelMoby: could you link me up?

[09:46] <eroomde> thanks
[09:46] <NigelMoby> :)
[09:46] <eroomde> hmm, they look like more than 6g!
[09:47] <NigelMoby> hey lazyleopard
[09:48] <NigelMoby> They do look mums chunk for 6g yeah

[09:51] <NigelMoby> Lol .. successful though?
[09:51] <fsphil> doesn't seem to have been activated yet
[09:52] <LazyLeopard> No. Missed the best chance pass.
[09:52] <LazyLeopard> The whole point of it being kept inside ISS was to make sure it would be active today. Ho hum...

[10:45] <hibby> Never posted to it, such is life. Just replying to the insurance from our point of viwew as a uni.
[10:46] <NigelMoby> Ahh, I've noticed a lot of the insurance q's are from unis
[10:47] <hibby> we, ehm, chose to ignore it...
[10:47] <hibby> as far as the uni knows, we've not done anything like this
[10:48] <NigelMoby> Well... its not mandatory is it?
[10:48] <SpeedEvil> AIUI no.
[10:48] <SpeedEvil> But you could in principle be liable for very big damages.
[10:49] <NigelMoby> Fair point
[10:49] <fsphil> with a NOTAM being issued, would you still be liable for an aircraft impact?
[10:49] <fsphil> if the pilot choose to ignore the notam for example
[10:49] <NigelMoby> Hope not
[10:50] <fsphil> there was a plane flying about quite low after hadie:2 launched
[10:50] <NigelMoby> :o
[10:50] <SpeedEvil> fsphil: I was meaning if it hit a car, and distracted the driver so they drove into a train, which sank an ocean liner.
[10:51] <fsphil> well you could do that without a hab payload
[11:01] <eroomde> one of those would be insured I guess
[11:01] <eroomde> we find insurance a very sticky issue too
[11:01] <eroomde> no one is interested in insuring such an un-lucrative activity
[11:02] <SpeedEvil> Indeed.
[11:02] <SpeedEvil> I currently want insurance for my car.
[11:02] <eroomde> but we have procurred it in the past for certain things
[11:02] <SpeedEvil> Which is a very ordinary car, parked on a very ordinary path.
[11:02] <SpeedEvil> The key is I don;'t want road cover, as I'm not using it.
[11:02] <SpeedEvil> Can't get it. (other than at stupid prices aimed at classic cars)
[11:03] <eroomde> household?
[11:04] <SpeedEvil> I've not found a household insurance that will cover cars.
[11:04] <SpeedEvil> 'Oh - you want out car insurance for that'
[11:13] <Laurenceb_> why do you need to insure the car?

[11:34] <NigeyS> hi Shuffty
[11:35] <hibby> I'm not the biggest android fan, overall
[11:35] <NigeyS> it does what it needs to do on my phone .. thats about as far as i've got with it
[11:36] <hibby> I had the issue that it really wouldn't do what I wanted.
[11:36] <hibby> I had a desire that regularly told me it didn't have enough RAM to make a phone call... bit of a fatal flaw.
[11:37] <hibby> I wanted to love it, too. Windows Phone 7 is, in my eyes, anyway, much more fun.
[11:37] <NigeyS> lol yup, that kinda qualifies as fatal
[11:37] <hibby> it's running beautifully.
[11:37] <NigeyS> mines been acting weird since 2.2.1 ..
[11:37] <NigeyS> it wont tell me if ive had missed calls or msgs until i try to make an outgoing call ..
[11:38] <NigeyS> so every morning i have to remember to make a call.. normally to voicemail to get any sms etc i may have recieved overnight
[11:38] <NigeyS> its as if the "phone" section of the os goes to sleep and doesnt wake up
[11:39] <Shuffty> Hey nigeys

[11:40] <Shuffty> How long have you got :-)
[11:40] <NigeyS> well im about to watch the last ever episode of waking the dead, so about 5 minutes..lol

[11:41] <Shuffty> Got my t68 talking the other day!
[11:41] <NigeyS> ach the asbo generation...lol
[11:42] <NigeyS> oo i did more work on my t68 last night
[11:42] <Shuffty> So now have the ntx2, t68 and gps talking - just got to get them all working together!
[11:42] <NigeyS> ive just to grab the gps data now and its all set :D
[11:42] <Shuffty> :-) when are you planning on launching and where from?
[11:43] <NigeyS> it was end of april , bbut thats in doubt, as i'm hoping to go up to cambridge and launch with the guidance of jonsowman it depends when he's available .. may sometime i guess
[11:43] <Shuffty> cool..
[11:44] <NigeyS> what avr are you using Shuffty, atmega on its own or an arduino uno / mega ?

[11:45] <Shuffty> Was going to use the uno, but am looking into the atmega on its own..
[11:46] <NigeyS> oki, word of warning if you go that route, you will get problems with the gps and t68 if you use newsoftserial and an atmega328 / 168 with only 1 hardware uart
[11:46] <Shuffty> Quite like this too.. http://www.timzaman.nl/?p=523&lang=en
[11:47] <Shuffty> So the uno route is better?
[11:47] <NigeyS> ah yes, tims done a good job, i have the ntx2 pcb from pictura here, very neat
[11:48] <Shuffty> got to dash - time for work.. :-(
[11:48] <Shuffty> :-)
[11:49] <NigeyS> Shuffty, possibly, if it has more than 1 hardware uart, its only if you throw software serial into the mix it plays up with the lassen, but ive spent 3 days with alot of help from people here getting a fix, so you will be ok either way, just dont be to surprised if you go the avr route and you get non-decodeable rtty
[11:49] <SpeedEvil> I wonder if anyoness bothered to write a n-ary uart.
[11:50] <SpeedEvil> That is - you tell it the baud rate(s), the pins, and it does it all in parallel.
[11:50] <SpeedEvil> On one timer interrupt.
[11:50] <NigeyS> pass, i was bloody close to getting a hammer to the gps module mind, talk about frustrating!
[11:50] <SpeedEvil> It's a bit more complex - but it's not _hugely_ so.

[12:53] <fsphil> though that one has it landing on a mountain
[12:53] <jonsowman> thats not too bad
[12:54] <fsphil> nah, there's a road not far from it .. though a climb up 400m may take me a while :)
[12:54] <jonsowman> yeah
[12:54] <fsphil> actually the road is just under 300m, so only a 100m climb
[12:54] <jonsowman> you could probably manage :P
[12:56] <fsphil> I'd better get the antenna finished tonight, plenty of time for testing so no gps surprises next time

[13:02] <fsphil> says they're going to activate it today sometime
[13:02] <Darkside> hopefully when i'm listening

[15:14] <Zupht0r> Yeah. US law is ambiguous as to the definition of 50 lbs or 50 lbs-f. ICAO law, however, gives a value in newtons which converts almost precisely to 50 lbs-f

[15:16] <Dan-K2VOL> and actually to cross the channel I think you guys need to abide by that one too
[15:16] <mattberryman> Hi all, I'd like to introduce myself. After spending a lot of time reading about HAB recently, I've managed to convince a friend to work with me to launch our balloon for some high altitude photography. We're modelling our payload on the GAGA / Icarus projects and will be hoping to launch from Cambridge in mid-May.
[15:17] <NigeyS> Dan-K2VOL, good point, worth checking up on
[15:17] <Zupht0r> We have a promising development involving a piece of aluminum stock with a groove inserted into an aluminum pipe with a ball bearing in the groove. Adjusting a tension nut adjusts the force at which the device releases.
[15:17] <Zupht0r> Or something like that.
[15:17] <eroomde> mattberryman: welcome
[15:17] <mattberryman> I expect that I'll be leaning on this group for the next few weeks for a bit of advice / support.
[15:17] <NigeyS> welcome mattberryman :_

[15:17] <eroomde> i look after the cambridge launch site, give me a shout nearer the time
[15:18] <mattberryman> Hi all, I've got a load of questions about the logistics of the launch; how to fill the balloon, how much helium to use etc - will you be able to offer some advice one that.
[15:19] <eroomde> yes
[15:19] <mattberryman> Thanks eroomde. I'll drop you a line when we've firmed up our launch dates.

[15:21] <eroomde> mattberryman: a lot of people find it profitable to come to a launch of someone else before theirs to get an idea of how it works

[15:26] <Nige|S> DanielRichman, on the subject of NSS ... is that object we specified yesterday tied to the 1 instance of nss? so if i call another instance for the t68, just doing bla.end wont effect it as its tied to the other instance ?
[15:27] <DanielRichman> Nige|S: you want to have multiple NSS objects for the same tx & rx pins?
[15:27] <Nige|S> no theyre on diff pins

[15:28] <Nige|S> but i do need 2 instances .. its working fine for the static msg i setup this morning, i wont know if it garbles rtty while its grabbing the gps for the sms until i finish that part of the code
[15:28] <DanielRichman> Sure you can have more than 2 nss objects
[15:28] <DanielRichman> you just can't have both of them active at once
[15:29] <Nige|S> oki, that's fine, i think i can work with that

[17:06] <TangoAlpha> is there an defined API to spacenear.us for uploading data without using dl-fldigi?
[17:08] <eroomde> yes
[17:09] <TangoAlpha> good
[17:09] <eroomde> but I can't remember where it is
[17:09] <TangoAlpha> lol
[17:10] <eroomde> it does exist though :) ask jcoxon if he pops on
[17:10] <TangoAlpha> i've looked through the dl-fldigi source and found a few things but nothing i do seems to work :-(
[17:10] <jonsowman> TangoAlpha: what are you trying to submit?
[17:11] <TangoAlpha> "data" strings just like dl-fldigi would do, but i'm not using dl-fldigi
[17:13] <jonsowman> in UKHAS format?
[17:13] <TangoAlpha> yes
[17:13] <jonsowman> you need to format an HTTP POST request to http://robertharrison.org/listen/listen.php
[17:14] <TangoAlpha> i already have my balloon comms in digital form so can't feed it through dl-fldigi

[17:14] <TangoAlpha> i tried that but it said something about expecting 0 fileds and i sent 1 field
[17:14] <jonsowman> required fields are "string" containing the telemetry, without $$ but including checksum
[17:14] <jonsowman> and "identity", containing the listener's callsign
[17:14] <TangoAlpha> that's what i was attempting to send
[17:15] <jcoxon> evening all
[17:15] <jonsowman> TangoAlpha: there needs to be an XML document for your payload on the dl server to tell it how to parse the data
[17:15] <jonsowman> evening jcoxon
[17:15] <TangoAlpha> ah
[17:16] <TangoAlpha> is there a method for posting that?
[17:16] <jonsowman> no, someone will need to set one up for you
[17:16] <jonsowman> have you got a couple of example telemetry packets?

[17:20] <jcoxon> super accurate altitude :-p
[17:20] <hibby> our latest SUNSET lanch logged most of it and only sent down relevant results, such as accelerometer data etc
[17:20] <TangoAlpha> it's what the gps is giving me
[17:20] <jonsowman> yeah you certainly don't need that accuracy in the altitude field TangoAlpha
[17:20] <Nige|S> now thats what you call a telmetry string
[17:21] <TangoAlpha> i can easily chop decimals places

[17:56] <fsphil> I flew the sparkfun version on the first flight, and the cool components one on the last one
[17:57] <eroomde> link?
[17:57] <fsphil> it has a nice wide angle lens
[17:57] <jonsowman> much between them, quality wise?

[18:03] <W0OTM> who is the traker dev?
[18:04] <jonsowman> W0OTM: why do you want it?
[18:04] <W0OTM> because I have the tracker running on my own server, but cant get into the admin
[18:04] <W0OTM> http://www.ihabproject.com/tracker/admin/
[18:05] <jonsowman> i didn't realise the tracker source was ever given out
[18:05] <jcoxon> that is editable in the config.php file
[18:05] <jonsowman> but if it's on your server, then the password will be in the source
[18:05] <eroomde> W0OTM: as an asside, with respect to http://twitter.com/#!/w0otm, in addition to asking people to retweet you can include a 'hashtag' for exmaple '#arhab' at the end
[18:05] <eroomde> most people who would be interested have searches set up that show them all tweets with #arhab in their contents
[18:06] <jonsowman> also griffonbot will relay it to this channel :)

[18:16] <Dan-K2VOL> that's correct Shuffty
[18:16] <Dan-K2VOL> you only need to do .begin once
[18:16] <Dan-K2VOL> after that just do Serial1.available to make that the active one, then its RX buffer will start filling

[18:18] <Dan-K2VOL> nice! what did you have to do?
[18:19] <Nige|S> DanielRichman and phil figured it out, it was the nss being open as rtty was sending, so had to call the close and begin in specific points

[18:21] <Shuffty> Thanks for that Dan - and thanks to you as well Nigeys...
[18:21] <fsphil> nss is an interrupt hog :)
[18:22] <DanielRichman> nah it's not
[18:22] <DanielRichman> It's just once it interrupts it uses blocking delays
[18:22] <DanielRichman> rather than a timer and more interrupts
[18:22] <DanielRichman> so it interrupts once and throws allt he timing out for an entire byte
[18:22] <DanielRichman> I dunno how you would do it without an interrupt
[18:22] <Nige|S> i vote for more hardware interrupts on atmega328's! lol
[18:23] <fsphil> I don't think you could
[18:23] <Nige|S> err uarts even
[18:23] <fsphil> at least not without blocking the entire program
[18:23] <Nige|S> see ive gone interrupt mad :(
[18:23] <DanielRichman> I reckon it could be done with more interrupts, but no blocking
[18:23] <DanielRichman> would be difficult though

[18:25] <Nige|S> phil, will this work .. send_sms(msg); ? calling the same msg that is sent to rtty, or is it cleared before it can grab it ?
[18:27] <fsphil> no that should be fine
[18:27] <Nige|S> oh cool, hmm its inside the loop though so that'd do it every new line .. have to figure out a timer for every 10 minutes or something

[18:49] <NigeyS> not to bad
[18:50] <NigeyS> even if only 1 message gets through on descent it'll narrow down a search area if the gps and or radio was to fail

[20:23] <DanielRichman> the trick with NSS is to just have it switched off all the time you're not using it.
[20:24] <DanielRichman> Arduino programs are all straight forward do this, then do this, then do this, so it's not too hard to do that

[20:35] <NigeyS> i get mine very well on 651.2
[20:36] <fsphil> and just to really confuse you, you can also receive it quite well on multiples of 434mhz :)
[20:36] <fsphil> at short range anyway
[20:36] <NigeyS> so id pick it up on 868 ?
[20:36] <fsphil> 868 or 869

[20:39] <Dan-K2VOL> yes harmonics are a funny thing. I tested up to the 5th harmonic on a transmitter for work

[20:42] <fsphil> neat
[20:42] <jcoxon> fsphil, so whats our first step
[20:43] <jcoxon> fsphil, perhaps i should reset it all
[20:43] <jcoxon> and see where we pop up
[20:44] <fsphil> to rule out any problem with what the spot is doing to the coordinates, I'd send a fixed nmea string that we know exactly what it should come through as
[20:44] <fsphil> 3127.6670,N,10153.1830,W should come through as: 31.4611, -101.8864
[20:45] <jcoxon> should we perhaps chose a string at the limits of our system
[20:46] <jcoxon> e.g.longitude 179
[20:47] <fsphil> or something closer to the meridian
[20:48] <fsphil> though if the nmea string isn't formatted right to begin with, any other test is invalid

[21:47] <fsphil> that's a really long string
[21:47] <fsphil> the apex team would be proud :)
[21:47] <TangoAlpha> ran out of things to monitor
[21:48] <TangoAlpha> right, i can leave that soaking overnight
[21:49] <TangoAlpha> time for a cup of tea :-)

[21:56] <jcoxon> hey fsphil
[21:56] <jcoxon> whats the prediction like?
[21:57] <fsphil> pretty neat so far: http://habhub.org/predict/#!/uuid=16f041bce2f18fa3b3ba1e81fd2ca766ced857ec
[21:57] <fsphil> still moving about a lot, but always predicted to land on solid ground
[21:57] <SpeedEvil> :)

[22:10] <fsphil> Looking at my last launch video, I think I had the parachute too low on the cord
[22:10] <fsphil> should I put it 2/3 of the way up?
[22:18] <MNSP_> evening chaps
[22:21] <MNSP_> lasseniq or fsa03? bearing in mind my experience :)
[22:21] <jcoxon> GPSbee
[22:23] <MNSP_> oh right, cam a bit out of left field jcoxon, but will investigate
[22:24] <fsphil> lol
[22:24] <jcoxon> so hte lassen is old and poor sensitivity
[22:24] <fsphil> gpsbee seems to have the best of both worlds
[22:24] <MNSP_> don't know how I missed that on the ukhas site?
[22:24] <jcoxon> lots of standing outside
[22:25] <jcoxon> the fsa03 has a weak antenna joint and has a habit of breaking just before launch
[22:25] Shuffty (Shuffty@188-221-227-102.zone12.bethere.co.uk) left #highaltitude ("Leaving").
[22:25] <jcoxon> the GPSbee is more solid
[22:25] <jcoxon> fsphil, what is mattlm's callsign?
[22:25] <fsphil> hmm.. something close to but not exactly M6MLP
[22:26] <jcoxon> m6mdp
[22:26] <fsphil> that's it
[22:27] <fsphil> one letter out
[22:32] <MNSP_> ok I see it on the seeedstudio site, any one come across a uk supplier at all?
[22:32] <jcoxon> at one point me!
[22:32] <jcoxon> though i went mad in the process
[22:33] <fsphil> indeed, but appreciated :)
[22:33] <MNSP_> well we wouldn't want that
[22:33] <jcoxon> MNSP_, i'd order them direct from them
[22:33] <fsphil> http://www.robotshop.com/eu/seeedstudio-50-channel-u-blox-5-gps-bee-receiver.html
[22:35] <MNSP_> ooo good find fsphil :)
[22:35] <fsphil> actually they're based in France, but close enough :)
[22:36] <MNSP_> now is there any extra bits, connectors and what not that I should get. I see there is a breakout board from skpang
[22:36] <fsphil> you'll also need to buy the antenna
[22:36] <jcoxon> MNSP_, yeah go for the breakout board + headers
[22:36] <jcoxon> it makes it nice and solid
[22:36] <jcoxon> but detachable
[22:36] <fsphil> I still need to get some headers
[22:37] <MNSP_> so gps module, breakout n header and the antenna
[22:37] <MNSP_> right
[22:37] <jcoxon> night all

[22:38] <MNSP_> this one? http://www.robotshop.com/eu/seeedstudio-embedded-gps-antenna-for-gps-bee.html
[22:38] <fsphil> yea
[22:38] <MNSP_> cool.... blimey wallets taking a bit of a hit this moth, lol
[22:39] <fsphil> poor moth
[22:39] <MNSP_> LOL, yeah alright
[22:39] <fsphil> the fsa03 is cheaper but impossible to get these days. also as jcoxon said really fragile
[22:39] <fsphil> and have a habit of breaking at 3am before a 11am launch :)
[22:40] <MNSP_> yeah, thats not on really
[22:40] <fsphil> my dream would be an fsa04 -- with a better attached antenna
[22:40] <fsphil> it'd be prefect
[22:40] <hibby> fsphil: maybe better packaging too?
[22:40] <MNSP_> am quiet happy to take a punt with this, just not really heard of it b4
[22:41] <fsphil> hehe, mine came in bubble-wrap
[22:41] <BrainDamage> dealextreme recently added gps modules
[22:41] <hibby> fsphil: did you launch it in bubblewrap though?
[22:41] <BrainDamage> they don't look too much unweidingly to solder
[22:41] <BrainDamage> you might want to check them
[22:41] <hibby> maybe housing would be a better word
[22:41] <BrainDamage> and they cost ~10¬
[22:41] <MNSP_> although I did have it on the seeed sit in my favourates for some reason
[22:41] <fsphil> hibby, polystyrene
[22:42] Zuph (~bradluyst@69.64.6.69) joined #highaltitude.
[22:42] <fsphil> trouble with dealextreme is it may not arrive this year :)
[22:42] <hibby> BrainDamage: what about the firmware though, will it do 20km+?
[22:42] <MNSP_> thats the clincher hibby!
[22:43] <BrainDamage> hibby: I don't know, just pointing them out, check the datasheet?
[22:43] <hibby> equally, I'm looking for cheap gps for my aprs units.
[22:43] <BrainDamage> I've seen the gps chipset widely used though, so I bet there's plenty of infos available
[22:43] <BrainDamage> http://s.dealextreme.com/search/gps+engine
[22:44] <fsphil> there's an fsa03 sitting in a Yorkshire field going cheap ;-)
[22:44] <BrainDamage> here dx shipping takes ~1 month
[22:44] <SpeedEvil> BrainDamage: not if you pay a little more
[22:44] <BrainDamage> right, but that little actually is not that little
[22:44] <fsphil> I ordered some stuff from dealextreme, some of it arrived within a week but the rest took 4 months
[22:44] <BrainDamage> I tried ems once, and it made package be stopped by customs
[22:44] <BrainDamage> so I got ems bill, and customs bill
[22:44] <fsphil> eek
[22:45] <MNSP_> gosh, I'd be screwing if that happened to me
[22:45] <BrainDamage> while regular mail usually passes customs without extra charges regardless of exceeding min charge trigger
[22:47] <BrainDamage> btw fsphil: where's there? uk?
[22:47] <fsphil> uk here yea
[22:47] <fsphil> got through customs fine though
[22:47] <fsphil> just took ages

[23:10] <Shuffty> Well that was a wasted night... cant get the gps to talk... figured it was a poor visibility thing, but having sat in the attick/ back garden / front garden, I'm thinking it's something else...
[23:11] <NigeyS> shuffty, jhave you hooked the gps up to the serial port to check its getting data when powered ? it should spit out a string of nmea with a load of ,,,, and a few 0's
[23:11] <Shuffty> directly to the pc?
[23:12] <NigeyS> yeah, connect the tx pin of the lassen to the rx0 pin on the arduino, power and gnd from arduino to the lassen, give me a yell when uve done that
[23:14] <fsphil> not directly to the PC though .. the PC's serial voltages are too high
[23:15] <NigeyS> oh yeah soz, lol
[23:15] <NigeyS> i meant via the arduino which i assume hes using via usb
[23:15] <Shuffty> ok - done that nigeys
[23:15] <NigeyS> just dont connect the lassen rx pin Shuffty
[23:15] <NigeyS> tx only
[23:15] <Shuffty> done
[23:15] <NigeyS> save you sending 5v through it and frying the gps module
[23:15] <Shuffty> :-)
[23:16] <NigeyS> ok 2 secs ill send you some code to get a 4800 baud connection to it
[23:27] <fsphil> night all!
[23:27] <Shuffty> night fsphil :-)
[23:28] <Lunar_Lander> night fsphil
