[07:24] <M0DTS> Morning..I just woke up! will go and look for live video shortly..Rob
[07:24] <Upu> morning
[07:24] <fsphil> not long up my self lol
[07:24] <fsphil> I've got a 1m 2.4ghz dish but it's in the attic
[07:24] <fsphil> at this distance it would be impossible anyway
[07:25] <fsphil> morning Upu
[07:25] <Upu> oo launch
[07:25] <Upu> RTTY 50 /350 on 434.650 ?
[07:25] Nick change: junderwood -> junderwood_M0JCU
[07:26] <junderwood_M0JCU> I think I have the signal. Still a long way off a decode
[07:26] Nick change: Upu -> Upu_2E0UPU
[07:26] <Upu_2E0UPU> I can hear that clear as day
[07:28] <Upu_2E0UPU> I should be able to decode that
[07:28] <Upu_2E0UPU> can someone check the settings for me ?
[07:28] <Upu_2E0UPU> 50 baud
[07:28] <junderwood_M0JCU> Same here. Good SNR but no decode
[07:28] <Upu_2E0UPU> 350 shift looks right
[07:28] <fsphil> try reversing?
[07:29] <junderwood_M0JCU> Reverse!
[07:29] <fsphil> it could be tx'ing backwards
[07:29] <Upu_2E0UPU> RV no checked
[07:29] <junderwood_M0JCU> Tones are switched
[07:29] <Upu_2E0UPU> got it

[07:31] <eroomde> where's the predicted landing spot?
[07:31] <Upu_2E0UPU> fsphil next time launch Hadie from Grimsby :)
[07:31] <eroomde> seems to be charging our way!
[07:31] <fsphil> lol
[07:31] <fsphil> I might launch from the dales, just to balance things out
[07:32] <g4tnx> Had a window of about 2 hrs before predictor puts it in the North Sea
[07:32] <Upu_2E0UPU> well loud and clear from here g4tnx
[07:32] <eroomde> g4tnx: is it due to land in east anglia?

[07:37] <junderwood_M0JCU> jcoxon, while you're at it, could you remove the point from last night in Grimsby!

[07:38] <junderwood_M0JCU> :-)
[07:38] <Upu_2E0UPU> well I'm quite relieved after last week I thought my kit was broken but this is clear as a bell
[07:39] <fsphil> sounds like you're in the shadow of the lake district from here
[07:39] <Upu_2E0UPU> yeah must be
[07:40] <fsphil> had this launch been a bit further north the reverse would happen
[07:40] <junderwood_M0JCU> Have to head out for an hour. I'll leave the radio on. Hopefully it will still be up there when I get back!
[07:40] <junderwood_M0JCU> 15 dB SNR. Wow
[07:40] <Upu_2E0UPU> 7.7m/s :)
[07:41] <Upu_2E0UPU> 8 dB here
[07:41] <Upu_2E0UPU> is that good ?
[07:41] <fsphil> 0 dB here :)
[07:41] <junderwood_M0JCU> It's 14.5 dB better than last week for me

[07:48] <fsphil> though we'll be leaving shortly for that, better get some breakfast
[07:48] <Upu_2E0UPU> is that spinning ?

[07:58] <jcoxon> yeah
[07:59] <Upu_2E0UPU> cut away ?
[07:59] <g4tnx> Nope
[07:59] <Upu_2E0UPU> it was spinning alot something gone wrong ?

[08:09] <M0JCU> that didn't last long! What was the burst alt?
[08:09] <fsphil> 13619m

[08:09] <M0JCU> :(
[08:10] <fsphil> never really got much above my horizon
[08:10] <RocketBoy> jcoxon: no problem - i was more worried that the payment had been swallowed by the bank
[08:11] <Colin-G8TMV> can see it in the waterfall still but can't hear it anymore - and never did get any decodes
[08:11] <RocketBoy> g4tnx: what range are you getting the video over and whats the dish size?

[14:26] <DanielRichman> ;-) well there's a 5v schematic on there somewhere. Whatever you do you definitely wanna play on a breadboard or use potentiometers
[14:28] <DanielRichman> there's a 3v3 schematic floating around somewhere. I'll see if I can find it
[14:28] <WillDuckworth_> yeah - definitely, anything's good. cheers

[15:58] <SpeedEvil> Really?
[15:58] <SpeedEvil> Should have seen if you could talk him into throwing your payload down.
[16:00] <fsphil> that's a plan .. put nuts on the payload cord
[16:00] <mattltm> lol.
[16:01] Hiena (~boreger@81.93.195.181.datatrans.hu) left irc: Remote host closed the connection
[16:01] <mattltm> Ok.. So I have a 12v PC fan that draws 220mA and I want to run it at 6V but using a 13.8V supply
[16:02] <mattltm> so 13.8/0.22 = 66.72 Ohm
[16:03] <mattltm> and 6V * 0.22 = 1.32W
[16:03] <mattltm> so I need a 1.32W 66.72 Ohm resister correct?
[16:04] <SpeedEvil> no
[16:04] <mattltm> Oh :(
[16:04] <SpeedEvil> It will draw less current
[16:04] <mattltm> about 1/2as much.
[16:04] <mattltm> ?
[16:04] <Darkside> http://pipe2.darklomax.org/pics/2011-06-10_Mt_Gambier_Foxhunting_Comp/
[16:04] <SpeedEvil> The simple way is to get a bag of 10 ohm resistors, and screw around.
[16:05] <SpeedEvil> However - you may run into problems starting - especially as the fan ages
[16:05] <mattltm> I have 2 x 100Ohm 0.75W that work fine but tey get a bit warm :)
[16:05] <SpeedEvil> you might consider for example using a 7805, with a couple of diodes on the 'common' pin to lift the voltage up a volt and a bit
[16:05] <SpeedEvil> Do you have 8 of the same resistor?
[16:06] <mattltm> Yup.
[16:06] <mattltm> A 7806 will give 6V @ 1A
[16:06] <SpeedEvil> That too.
[16:07] <mattltm> Was trying to do it with odd bits from the junk box.
[16:07] <SpeedEvil> If you're using 2 in parallel, you can instead use 2 sets of 2*2 resistors
[16:07] <fsphil> last photos here: http://www.flickr.com/photos/fsphil/sets/72157626013096240/
[16:07] <SpeedEvil> 2 resistors in parallel/series make up the same resistance as the original resistor, but can cope with 4* the power
[16:08] <mattltm> Oh, good plan..
[16:08] <SpeedEvil> That is quite tall!

[16:09] <fsphil> thin and breakable
[16:09] <jcoxon> i'd get lines up there
[16:09] <fsphil> I just need a better way to attach the knife
[16:10] <fsphil> climb up?
[16:10] <jcoxon> no throw lines up and over
[16:10] <jcoxon> then you'd be able to 'pull' it down

[16:30] <fsphil> very clear
[16:30] <Upu> so whats the next plan fsphil ?
[16:31] <g4tnx> Will get the video tomorrow night and do something with that, should have recorded the whole flight
[16:31] <fsphil> jcoxon suggested looping a cord around it, and using that to drag it out of the tree
[16:31] <fsphil> did you capture any of the 2.4ghz video g4tnx?
[16:32] <fsphil> so I'll try combine that with mattltm's idea of a catapult
[16:32] Nick change: g4tnx -> g4tnx-lee
[16:33] <fsphil> I can report that it's stopped transmitting :)
[16:33] <g4tnx-lee> 2.4ghz is on tape so has to be converted
[16:33] <fsphil> oooh retr
[16:33] <fsphil> retro
[16:34] <g4tnx-lee> seems video recorders are better at dealing with weak signals than solid state
[16:34] <g4tnx-lee> so the experts tess us
[16:34] <fsphil> possibly, lossy codecs don't like static
[16:36] <g4tnx-lee> have used a pc capture card in the past when we put the camera on a kite & model plane but it didnt perform as well
[16:38] <fsphil> a lossless codec like huffyuv might do the job, but the file sizes will be enormous

[20:03] <MrCraig> (if I miss spelt that name, please allocate points for the effort)
[20:04] <MrCraig> what's round three then fsphil? Longer pole?
[20:04] <fsphil> throw rope over the payload with pole, use that to drag it down
[20:06] <MrCraig> are there many branches between you and the payload ?
[20:06] <fsphil> few yea
[20:07] <MrCraig> :-/ I was thinking it might pay off to try to get a rope over the chute ties and bring it back to ground, that way you could latch loop the rope, as you pulled it'd tie off around the chute ties giving a good grip.
[20:08] <MrCraig> next one gonna be illuminous paint and a towing eye I reccon :)
[20:10] <fsphil> good idea lol
[20:10] <fsphil> it'll definitely be florescent
[20:10] <fsphil> loop on the bottom is a good idea too
[20:13] <MrCraig> I should get into gear and prep artemis for another flight. Kinda bummed that my pc died though, I have no genuine serial or parallel ports available to me now.
[20:14] <MrCraig> I wanted to debug the circuit because of the fault that occurred on flight 1 - and I probably should 16-bit the checksum.
[20:15] <fsphil> I've been using those usb <> serial dongles
[20:15] <MrCraig> I have one usb<>serial cable - and I know it works for some higher baud rates but fails on lower rates (found that out the hard way) and it does drive my micro programmer.
[20:15] <fsphil> odd
[20:16] <MrCraig> It's unfortunate though that unless I get my hands on another one I'll have to keep swapping the cable onto the max232 etc
[20:16] <fsphil> though I've never used this one below 4800
[20:17] <MrCraig> Yup - while I was developing the board - I swapped the cables for the programmer and the max232 debug circuit prior to lowering the baud rate (as per your advice, ty), I struggled for a while and then just happened to try it on the other port - all worked.
[20:17] <MrCraig> That was the day I rewrote the timing loop about 6 times trying to get it working.

[20:19] <fsphil> loops are fun
[20:19] <MrCraig> But the true upset is - I abandoned the idea of using the cnc mill for the pcb because I set myself a deadline and the learning curve on the software was quite steep. Since then I've been able to get the cnc mill to pen out a pcb (not my own design, just a basic pattern) and was all set to start developing my own board... but need a parallel port to drive the machine.
[20:19] <fsphil> nooooo
[20:20] <MrCraig> yup, it cuts.
[20:20] <MrCraig> lol
[20:20] Action: SpeedEvil ponders if he should try to sell MrCraig his 386/20 motherboard.
[20:20] <MrCraig> I'll have to continue to make do with strip board.
[20:20] <fsphil> I've a few old PC boards too but I've no idea if they work
[20:20] <fsphil> there are PCI parallel card
[20:20] <fsphil> +s
[20:20] <MrCraig> actually SpeedEvil, I'd quite like that from a nostalgic point of view but the cnc driver requires at least a P95
[20:21] <MrCraig> I'll pick up a reasonably new board soon and stick in a PCI parallel port - I need a replacement PC because this laptop is breathing it's last breath.
[20:22] Action: fsphil notices fsphil-eee after the mention of laptop -- forgot that was still on
[20:22] <MrCraig> I lost a car, a PC and a laptop all inside two months :-( Got the laptop working again but damaged the keyboard strip and I don't know how long it'll last - the cpu overheats, and there's nothing wrong with the fan or sink.
[20:23] <fsphil> grrr cars
[20:23] <MrCraig> yup. I'm a full time pedestrian now but I'll rent a car for flight days. It might make it more expensive as a hobby, but I save a fortune all year round.
[20:24] <fsphil> hehe true- my own car broke a few weeks back, saved a fortune on fuel ;)
[20:24] <MrCraig> That-is, when kind friends don't volunteer to drive <grin>
[20:24] Action: SpeedEvil fucking hates busses.
[20:24] <SpeedEvil> I hate the nonexistant sort most.
[20:25] <SpeedEvil> Having issues getting licence, due to fatigue. I tend to get really tired 3/4 the way through the test, and fail.
[20:25] <MrCraig> luckily I live on the same road I work on - I only used that old motor for trips to see family, and I'd been modifying it specifically for habbing - but a snapped timing belt on the M25 killed it. Repairs worth more than the car.
[20:26] <fsphil> oooh snap MrCraig, timing belt
[20:26] <MrCraig> Yeah, sucks right? lol
[20:26] <fsphil> totally -- needs a new engine
[20:29] <MrCraig> :-( Well I decided better shot of it because the car only cost me £400 a mere 18 months before it died. It'd had a service at which point I was quite flush so I said - full service and check her over for anything that might need doing. Somehow they failed to consider the timing belt as either part of a full service or as something that might need to be changed.
[20:29] <eroomde> i once did an engine rebuild after the timing belt went
[20:29] <Laurenceb_> diesel?
[20:29] <eroomde> when i saw all the bits taken apart in my garage i was terrified
[20:29] <SpeedEvil> Full engine cores for my car seem to turn up on ebay at ~150
[20:29] <SpeedEvil> Which is nice
[20:29] <SpeedEvil> I just need to get it on the road.
[20:29] <eroomde> realised i'd really jumped in at the deep end
[20:30] <SpeedEvil> eroomde: I'd be terrified trying that.
[20:30] <MrCraig> agrees with eroomde having done three roadside head gaskets in my time.
[20:30] <SpeedEvil> http://www.mauve.plus.com/fascia.jpg
[20:31] <SpeedEvil> This was the result of a quick 10 minute job changing a heater control knob
[20:31] Action: SpeedEvil stabs the haynes book of lies.
[20:31] <MrCraig> lol 10 minute job
[20:31] <eroomde> yes, haynes got me through the rebuild
[20:31] <eroomde> but god it can fool you
[20:32] <SpeedEvil> The above was due to a redesign that eliminated a service panel in the fascia.
[20:32] <SpeedEvil> Of course - I only noticed this after I'd pushed the heater panel back into inaccessibility
[20:33] <MrCraig> The most scarey experience I had though was my first -new- car, a ford focus back when those things were new. My brother (mechanic) volunteered to install a sound system. As I approached him working on it, seeing all of the interior stripped out and hearing him utter things like "oh spare part" or "design after thought" (which he did intentionally to freak me) I vowed never to allow myself to see the work being done
[20:33] <SpeedEvil> :)
[20:36] <MrCraig> ok, so - I need habbing assistance at some point when a future flight takes place. Thus far, I've only ever decoded my own transmissions - never a string of anyone elses. Part of it I'm sure is location, I'm in a valley - but I must also be getting something wrong because I certainly should have been able to pick up fsphil's recent flight. So if anyone is willing to do a check-list with me for an upcoming flight, I'd
[20:36] <fsphil> you need to try /P -- somewhere with a clear horizon
[20:37] <MrCraig> comes down to the car issue again - I'd get up to the top of the hill if I had one :-/
[20:37] <fsphil> even distance hills can be a problem -- the lake district seemed to cause problems for Upu and others in that area
[20:37] <fsphil> know that feeling
[20:38] <fsphil> where abouts are you?
[20:38] <MrCraig> I know that the day after my first flight, I was picking up a transmission in the midlands from a cambridge launch.
[20:38] <MrCraig> I'm in Kingston Upon Thames, Leatherhead inside of mole valley.
[20:38] Dutch-mill (3e2d7a74@gateway/web/freenode/ip.62.45.122.116) joined #highaltitude.
[20:39] <MrCraig> I'm also in a rented flat, so can't do much about antennae and am surrounded by concrete - but I think I'll have better luck if I relocate to my works office up the road.
[20:39] <fsphil> you should be good for any of the cambridge launches
[20:39] <fsphil> aah
[20:40] <fsphil> buildings can be a problem - I can't receive anything upstairs in the house, or even the attic - only signals I get are from the antenna on the roof
[20:41] Dutch-mill (3e2d7a74@gateway/web/freenode/ip.62.45.122.116) left irc: Client Quit
[20:42] <MrCraig> Well there is an interesting idea that probably won't work but I'm considering trying anyway. In my flat there's both a tv antenna socket and a radio socket. I'm thinking if I patch into the radio one I just might be able to use that antenna which is on the roof... it's probably not ideal for the frequencies but it's a thought. So long as I don't key the transmitter and damage all connected devices in the building I
[20:44] <fsphil> unlikely -- the radio socket is probably filtered to block anything above 200mhz-ish
[20:45] <MrCraig> foiled again
[20:45] <fsphil> though the height may outweigh that
[20:45] <fsphil> worth a try, but make sure there's no power coming out of the socket
[20:45] <MrCraig> multi-meter at the ready
[20:48] <fsphil> have you got access to the roof? :)
[20:48] <MrCraig> In all honesty, I've never been up there to find out.
[20:49] <MrCraig> Tomorrow is sunday - I'll see if it'd be possible to get up there with the radio and a laptop
[20:49] <SpeedEvil> Careful you don't do a Rod Hull.
[20:49] <fsphil> yea, be wary of slopes and heights
[20:50] <SpeedEvil> I cheat.
[20:50] <MrCraig> :-) thankfully it's a mostly flat roof, only the odd solar panel to worry about
[20:50] <SpeedEvil> If I have to work on the slope of the roof, I have a safety rope over the top.
[20:50] <fsphil> ooh PV or water heating?
[20:51] <MrCraig> I'd have to guess water (not knowing what you mean by PV) because it was recently damaged and leaking vast amounts of water right into the drainage.
[20:52] <fsphil> photovoltaic, electric panels
[20:52] slothearn (~euclid@71.173.193.158) left irc: Quit: Lost terminal
[20:52] <SpeedEvil> photovoltaic
[20:52] <SpeedEvil> yeah
[20:52] <MrCraig> ahh, semiconductors basically right?
[20:52] <SpeedEvil> Indeed.
[20:52] <fsphil> every house should have a few
[20:53] <BrainDamage> pv leaks semiconductor glass :p
[20:53] <MrCraig> Well, I'm certain there are electric pumps to boost the water pressure in these blocks (there are pumps for waste water) and so the electricity to supply them is probably all that is generated, and so the recent leak probably did more damage in terms of 'carbon footprints' than the device will ever save.
[20:54] <SpeedEvil> It depends.
[20:54] <MrCraig> photoelectric devices are likely a better bet.
[20:54] <SpeedEvil> Solar-thermal water heaters actually can be worth it.
[20:54] <SpeedEvil> _much_ more so than solar-pv.
[20:54] <fsphil> yea
[20:54] <MrCraig> That's suprising to me
[20:54] <SpeedEvil> A kilowatt of solar-thermal panel will run you around 200 quid.
[20:54] <fsphil> but only if you need hot water
[20:55] <BrainDamage> photovoltaic is very expensive, and needs a lot of energy to be produced
[20:55] <SpeedEvil> A kilowatt of solar-PV - at least a thousand, or more.
[20:55] <MrCraig> could they be entirely convection driven?
[20:55] <BrainDamage> so the break-even point is very high
[20:55] <SpeedEvil> MrCraig: yes - but that is annoying as it means a big bulky tank on the roof.
[20:55] <SpeedEvil> MrCraig: Which is actually illegal under UK regs.
[20:55] <BrainDamage> also carbon footprint is a measure of feet trails from coal miners?
[20:56] <SpeedEvil> (or more accurately, is not excempt as other solar panels are)
[20:56] <MrCraig> ugh, what isn't illegal in the UK - or hideously expensive.
[20:56] Action: fsphil is probably breaking a few laws just by sitting here
[20:56] <MrCraig> lol @ BrainDamage
[20:56] <BrainDamage> MrCraig: if it's sane, meaningful and common sense, you can be sure it's illegal in any "civilized" country, not just uk
[20:57] <MrCraig> lol now I wonder if my usual comparison in such issues would be considered "civilized"
[21:01] <MrCraig> time to run out for some late night bio fuel. Goodnight folks.
[21:01] <fsphil> night MrCraig
