[09:04] <cm13g09> fsphil: I insist on a planned power shutdown every 3 months to test power outage procedures ;)
[09:05] <fsphil> yea we've started doing similar here
[09:05] <cm13g09> You can guarantee if you don't do them, you'll have a problem
[09:06] <cm13g09> we do ours very carefully, by taking out power to the UPS only (and leaving the rest of the network up) so we can monitor the shutdown

[09:07] <fsphil> pro tip: make sure the ethernet switch your network enabled UPS is connected to, is powered by said UPS :)
[09:08] <cm13g09> fsphil: well, in most cases I've dealt with "Ensure network switch that allows communication between the servers with the management agent on it and the server directly connected to the UPS is on the UPS"
[09:08] <fsphil> whoever setup ours didn't
[09:08] <cm13g09> also "Ensure shutdown sequence is sane so that the server connected to the UPS is the last one out"
[09:09] <fsphil> the UPS powering the switches would fail before the UPS powering the servers
[09:09] <cm13g09> whoops!
[09:09] <fsphil> but the servers would never get the message to shut down
[09:09] <fsphil> was a right mess

[09:44] <ibanezmatt13> Can't believe that I got several green decodes of BALYOLO last night. I might get myself a proper radio rig set up, it felt awesome :)
[09:44] <Joel_re> whats a green decode?
[09:44] <ibanezmatt13> Where you decode each character of the datastring in dl-fldigi correctly
[09:45] <Geoff-G8DHE> The background goes GREEN to show success as opposed ro RED
[09:46] <eroomde> Joel_re: dl-fldigi has a red/green system for fail/pass of the string with the checksum
[09:46] <Joel_re> oh
[09:46] <Joel_re> I havent played with that
[09:46] <ibanezmatt13> Do you reckon a 5 element Yagi would perform better than my magmount on a window ledge?
[09:47] <Geoff-G8DHE> When the balloon is down the lne of the aerial yes!
[09:48] <ibanezmatt13> Right, I'll try that next time
[09:48] <fsphil> it'll be more work keeping the yagi aimed
[09:48] <ibanezmatt13> That's what I was thinking
[09:48] <Joel_re> can someone look at this crc code and tell me if it looks fine http://bpaste.net/show/188352/
[09:49] <Joel_re> is there anyway I can test it
[09:49] <Joel_re> I mean to verify
[09:49] <fsphil> I like to test against this: http://www.lammertbies.nl/comm/info/crc-calculation.html
[09:49] <fsphil> CRC-CCITT (0xFFFF) is the one we use
[09:51] <Joel_re> ok
[09:52] <fsphil> uint8_t crc_new = (unsigned char)(crc >> 8) | (crc << 8);
[09:52] <fsphil> I'm pretty sure this will always result in 0
[09:53] <fsphil> uint8_t crc = 0xffff;
[09:53] <fsphil> no chance :)
[09:53] <fsphil> 0xffff is a 16-bit value
[09:53] <Joel_re> hrm, right

[10:12] <gonzo_> ibanezmatt13, unless the balloon is close to you, then you will probably not need to change the aim of the yagi through most of the flight. And a 5lele will have quite a wide beamwidth anyway. So you will probably be able to point it once and leave it there
[10:13] <gonzo_> even with my 17ele beam, at a few 100's opf km away, I hardly need to adjust it for the whole flight

[10:32] <UpuWork> been sat with them for 3 weeks
[10:32] <navrac_work> really? I guess they cant work out what classification to put it under.
[10:33] <UpuWork> taken them 3 weeks to decided paid it yesterday should turn up today
[10:35] <navrac_work> now all you need is a 1.8m satellite dish a vacuum pump and you could sell ready made foil baloons to us all
[10:35] <Geoff-G8DHE> Hu Hu Several years ago, sent Amateur TV Tx to French station, customs thought drugs under board, not removable, so hacksaw down thru middle of box/board then sent it on!

[10:37] <Geoff-G8DHE> we sent it less connectors attached and he soldered them on at the other end!

[11:12] <G8APZ> BALYOLO - batteries died last night around 10pm
[11:12] <daveake> Don't expect this sort of timekeeping later :)
[11:13] <BALYOLO> Thanks - we think it may be still flying ...
[11:14] <G8APZ> BALYOLO Quite likely given that it seemed to be a float and at a decent altitude - was received over a wide area
[11:14] <BALYOLO> looking back at data we'd only just cleared 1000m when we flew over Milton Keynes - which meant an ascent rate of less than 1 m/s
[11:14] <fsphil> most floaters will burst shortly after sunrise
[11:14] <G8APZ> BALYOLO Hope you have a "roaming" SIM card in the backup tracker

[11:14] <eroomde> yes it's probably floating
[11:14] <eroomde> that's barely any ascent rate at all
[11:15] <BALYOLO> Yep we have a GSM that will kick in once it drops below 1000m

[11:15] <SpeedEvil> BALYOLO: It doesn't always do that - especially if it's coming down rapidly - and landing in a hollow.
[11:15] <BALYOLO> I have reviewed the filling - it appears that Sammy and Ben did not follow procedure

[11:18] <BALYOLO> pity - I'd go with a 0.6 m/s ascent rate and payload of 1.1 kg
[11:19] <BALYOLO> so looks like it went NE for a long time before it hit the jet stream, then started heading SE
[11:19] <eroomde> tongue in cheek of course, but you do want to be aiming for an ascent rate in the rnage of 4-5m/s

[11:19] <BALYOLO> Sammy is one crazy fool
[11:20] <eroomde> well, also the tracker launching without a gps lock - definitely worth checking it's all nominal three times before letting go
[11:20] <BALYOLO> lol - yep about 50% more than we should have I guess
[11:20] <fsphil> where you measuring the neck lift of the balloon while filling it BALYOLO?
[11:20] <eroomde> although i don't know if it was working but then lost lock immediately after launch. as far as i know no-one received any packets from it with a gps lock

[11:23] <UpuWork> BALYOLO sorry about yesterday
[11:24] <UpuWork> are you planning on launching again ?
[11:24] <eroomde> the problem with guestimating is that lift is proportional to the cube of balloon diameter. s if your guess of diameter is off by, say, 15%, your lift will be only just over half what you need
[11:24] <BALYOLO> we'll have another go in the next few weeks; I'm sure they will have learned from it :0
[11:24] <UpuWork> I'll replace the Habduino foc
[11:24] <UpuWork> as the code was my fault
[11:24] <cuddykid> up
[11:24] <UpuWork> however few questions
[11:24] <UpuWork> the GPS antenna where was it in relation to cameras etc ?
[11:24] <BALYOLO> UpuWork - fire away
[11:25] <UpuWork> and what cameras were in the payload ?
[11:25] <BALYOLO> I'll get the launch team to answer - 1 sec
[11:25] <G8APZ> Upu some code "walkthroughs" with others may be in order!!

[11:27] <BALYOLO> The gps reciever was in its own corner away from any electrical equipm
[11:27] <BALYOLO> only polystyrene around it
[11:27] <UpuWork> did the payload spend a significant amount of time in the car or somewhere before it was launched ?
[11:27] <BALYOLO> same as last launch when it worked
[11:28] <UpuWork> you managed to get a bug which I've not seen or been able to reproduce in about a year and a half
[11:28] <BALYOLO> no, turned on and flashing green only 20 mins before launch
[11:28] <UpuWork> but it was always generated when the GPS was jammed by something like a camera
[11:29] <eroomde> did you decode the signal?
[11:32] <fsphil> the chinese ebay cameras are good at blocking gps

[11:35] <navrac_work> habes in my blind spot - a two storey tin roofed huge barn
[11:35] <daveake> I was away (making a payload ...) and dl-fldigi happened to tun itself in :)

[11:35] <fsphil> we'll have dl-fldigi making tea soon
[11:35] <eroomde> BALYOLO: did it have a gps lock on the ground - did you decode the telemetry?
[11:36] <navrac_work> ah still got habe
[11:36] <BALYOLO> It had gps lock (flashing green) but we hadn't decoded
[11:37] <eroomde> you really really must do that
[11:37] <daveake> Never ever launch without decoding (and preferably uploading) on the ground.
[11:37] <eroomde> it's mad to let go of a balloon without checking the telemetry looks sane
[11:37] <eroomde> really mad
[11:38] <UpuWork> As far as we can tell from M0JCU's initial upload it never had a lock
[11:38] <G8APZ> I make the shift nearer 480
[11:38] <G8APZ> 22dB/n in Essex
[11:38] <navrac_work> well lets face it we always make mistakes on our first launch and second.. and third..
[11:38] <gonzo_> traces of telem in poole
[11:39] <eroomde> navrac_work: sure, but people who don't have a working decoding solution at launch almost invariably go wrong
[11:39] <eroomde> there's mistakes and there's silly
[11:40] <daveake> HABE has some gas in it
[11:40] <navrac_work> true, but until you've done one launch you don't realise what is important
[11:40] <G8APZ> HABE sigs not stable... drifting up/down
[11:40] <eroomde> you do if you have people telling you what's important
[11:40] <G8APZ> not decoding here either!
[11:40] <gonzo_> no-one ever learns by other's mistahkes
[11:41] <gonzo_> nice short telem strings though
[11:41] <fsphil> our first launch was done very carefully, following all the guides on ukhas.org.uk
[11:42] <fsphil> and two radio trackers :)
[11:42] <fsphil> both chase cars had receivers

[12:20] <G8APZ> Something I never understood... why do payloads hang on many metres of cord? Is there something relevant with a long bit of cord?
[12:20] <craag> G8APZ: More cord keeps the payload more stable
[12:21] <jonsowman> reduce swing period
[12:21] <craag> Also increases the chance of something not being up the tree that you can pull on
[12:21] <G8APZ> really? seems like a pendulum swinging to me!

[16:19] <PE2BZ> TnX Steve, that improves even more.
[16:20] <M0TVU> both seem very patchy here in Brum
[16:20] <Steve_G0TDJ> Also widened my recieve filter bandwidth to 96
[16:20] <G6WTR> BUZZ seems to go best on 50/505 for me as G4MYS
[16:21] <fsphil> 444.4km away
[16:23] <G6SUQ> Steve_G0TDJ: widening the bandwidth usually helps ... I normally have mine at about 200
[16:23] <Steve_G0TDJ> G6SUQ: Wow, that is wide. I think I get too much QRM for that.
[16:24] <G6SUQ> seems to work okay for me
[16:25] <G6SUQ> if you wanna RX SSDV it needs to be about 600!

[16:29] <es5nhc> I have also heard sporadic E events. Italians and Turks here
[16:30] <es5nhc> The Finnish site which I heard a lot of stuff yesterday is 247 km from me
[16:30] <G6SUQ> es5nhc: yes, Sp-E ... was in July, so it usually happens at that time of year

[16:32] <es5nhc> Yeah... I bought an HT with FM BC tuner in summer 2011... and right in July I was scanning the band and heard an Italian language commercial suddenly
[16:32] Nick change: myself_ -> myself
[16:33] <fsphil> Used to see the same thing on analogue TV. A few summers we'd get the stations from the Border area between scotland and england coming in as strong as the local ones
[16:33] <G6SUQ> the one that I heard was a station carrying a political rally; didn't understand it, but made a note of the station ident and freq, and checked when I got home later
[16:34] <es5nhc> Same here with Finnish analog TV... Seldom I have also caught Finnish digital TV
[16:34] <es5nhc> Not that I have had time to make much effort in last years.
[16:34] <fsphil> I've never even looked for distant dvb stations
[16:35] <es5nhc> I have actually my antenna in the attic aimed to adjacent DVB-T transmitter(Same direction with Koeru, Tallinn and Espoo) rather than local transmitter ca 15 km southeast from me.
[16:35] <G6SUQ> anyway, back to balloonatics ... can anyone foresee and problems with a pico launch at midnight?

[16:51] <G6WTR> ok lets try 8000 and see what SIbot does!
[16:51] <aadamson> didn't it have *parachutes* I thought I saw those in the streamers and what would it's descent rate be if under a small chute

[16:54] <x-f> because it likes SI units :P
[16:54] <PE2BZ> On which end ?
[16:54] <eroomde> yo, what's 30m/s descent at 20km equates to a sea-level landing vertical velocity of 8m/s
[16:54] Action: es5nhc also likes SI units
[16:54] <eroomde> which is kind of high
[16:54] <G6WTR> but not 0.61M?!
[16:54] <G8APZ> it needs a digit then!!
[16:54] <eroomde> that wasn't a question, sorry
[16:54] <es5nhc> 2 ft = 0.6096 m
[16:54] <SIbot1> In real units: 2 ft = 0.61 m
[16:54] <eroomde> what i meant to say way, 30m/s vertical at 20km alt means 8m/s at sea-level

[17:00] <SIbot1> In real units: 1 lbs = 454 g
[17:00] <es5nhc> well, 1 ft equals 30,48 cm... so yeah, 30 ft is 9.14 meters
[17:00] <SIbot1> In real units: 1 ft = 0.30 m
[17:00] <g0pai_ian_> Observation: 434.500,10MHz seemed the more stable frequency over the flight. 434.649,49 drifted high during flight. So interested if tx were both same type?

[20:10] <edusupport> Is it legal to use a transmitter to send a low frequency signal to locate the payload on the ground (i think somone mentioned it last night), and could it be active during the whole flight?
[20:10] <mclane> what is low frequency?
[20:10] <edusupport> 1hz
[20:10] <edusupport> like a pulse
[20:10] <SpeedEvil> hah
[20:11] <SpeedEvil> Where do you plan to get the 300000km long antenna?
[20:11] <mclane> how do you want to detect that?
[20:11] <mclane> yea, large antenna!
[20:12] <edusupport> Ok maybe i am explaining it wrong lol short burst high frequency
[20:13] <mikestir_> you can DF the normal RTTY beacon from a good distance on the ground
[20:13] <mikestir_> even if it's too weak to decode you can still get a bearing

[21:17] <edusupport> Ok 1hz oscillator + NTX2 thats what I meant but can we use it
[21:18] <mikestir_> you mean so you have a 1 hz on/off beep to listen for?
[21:19] <edusupport> Yes i have it running but I just want to know is there any reason why we cant use it as far as HAB goes
[21:19] <fsphil> why not just transmit rtty?
[21:19] <mikestir_> it would be legal, but as fsphil says
[21:19] <edusupport> Its a standby we are using a pi
[21:20] <mikestir_> as a backup beacon, yes it would be fine
[21:20] <mikestir_> you'd have the issue of getting two antennas on the payload without them interfering though
[21:21] <Geoff-G8DHE> A plain carrier is easier to DF then any pulsed signal
[21:21] <Geoff-G8DHE> maybe 30 seconds on 1 minute off to allow you to get to another location for a cross bearing or longer gap id power is concern
[21:22] <edusupport> We have a pi with a few sensors picam etc how far away would they have to be
[21:22] <mikestir_> the problem with a carrier is that it would be hard to identify against possible interferers
[21:22] <mikestir_> just DFing the rtty is almost as good as a dead carrier, but also has the advantage of being positively identifiable
[21:23] <edusupport> Geoff-G8DHE good idea thanks
[21:23] <Geoff-G8DHE> woudn't dispute that give it a tone modulation, but don't pulse it, the brain works on hearing the noise level increase decrase as you rotate aerial
[21:23] <Geoff-G8DHE> pulsing rapidly even 1 second on/off is to fast
[21:24] <SpeedEvil> 20hz is ok
[21:24] <SpeedEvil> much slower than 10 is not
[21:25] <mikestir_> take decent headphones for the receiver. you will probably pick the right bearing on what might seem like gut feeling even before you can hear the tone
[21:26] <mikestir_> we managed about 2 miles, wrong side of a ridge and payload antenna bent up underneath on the ground
[21:28] <mfa298> if you're doing anything more than just a simple on/off (555 timer circuit) then you're probably using an arduino so why not add a gps and have it send lat/long as well as a proper backup transmitter
[21:30] <edusupport> It is a 555 but could use a pro mini :)
[21:34] <tweetBot> @NORB_HAB: NORB 4 stencil is finally complete! Getting nearer to the flight of N-1 ;) #ukhas http://t.co/yhUhOuZQ0N
[21:41] <mfa298> using something like a 555 will give something really simple. but as others said for DFing you want something that's distinct (so you know it's your basic tracker and not some other random device) which might be pushing a single 555 a bit far.

[22:02] <Pascend-Ross> Does anyone ever use microwave for tracking habs?
[22:03] <fsphil> don't believe any one has
[22:03] <fsphil> it would be quite difficult
[22:03] <Lunar_Lander> 2.4 GHz and so on?
[22:03] <SpeedEvil> 470MHz is most way to microwave
[22:03] <Lunar_Lander> only for ATV on the Continent as far as I know
[22:03] <mfa298> Pascend-Ross: it's been talked about (2.4GHz and 5GHz) but I think the thought is that the link budget might be an issue - airborne doesn't allow that much power
[22:04] <fsphil> I'll fly a 2.4ghz module at some point
[22:04] <fsphil> just to see
[22:04] <Lunar_Lander> a professor at the university of applied science in Münster, germany, whom I know, launched a live videolink on his HABs
[22:04] <Lunar_Lander> and he used something in the Gigahertz range
[22:04] <Lunar_Lander> and homemade parabolic antennas on the ground
[22:05] <fsphil> very likely one of the amateur bands
[22:05] <mfa298> If I ever get the bits working I'd like to try the wifi idea to try video streaming even if it's only good for a couple of km
[22:05] <fsphil> 1.3ghz or similar
[22:05] <fsphil> indeed
[22:05] <fsphil> I'll probably set mine up as an access point
[22:05] <Pascend-Ross> I was jist looking at what they did with red bull stratos, seems like they used 2GHz microwave
[22:05] <mfa298> I ought to spend a bit more time getting it working locally then try some range tests
[22:06] <mfa298> Pascend-Ross: we're mostly limited to ISM bands/powers unless you want to pay (and potentially show the technical expertise) to get some experimental permit
[22:07] <daveake> I have a 1.3GHz pair here to have a play with
[22:08] <Pascend-Ross> I mean...streaming at 60 frames full HD....I want! I should probably start with ssdv and work up :D
[22:08] <fsphil> lol
[22:08] <fsphil> my next flight might have "video"
[22:10] <mikestir_> there's some interest at my local AR club in tracking a microwave downlink. They have an az/el rotator on top of a lighthouse
[22:10] <mfa298> Pascend-Ross: unless you have a special license (i.e. experimental permit) you'll struggle with 60fps full frame (although 60fps sounds somewhat american)

[22:24] <aadamson> http://www.hobbyking.com/hobbyking/store/__26830__2_4Ghz_4_Channel_AV_Transmitter_500mW_FPV.html - the FPV RC guys use all kinds of these, they are avaible on 900mhz, 1.2, 1.3, 2.4, 5.8, etc
[22:25] <aadamson> various output powers too
[22:25] <Darkside> analog TV is doable
[22:25] <Darkside> though VSB ATV will work better than the FM ATV those moduls will do
[22:26] <aadamson> there are all kinds of options, really small ones/light weight ones as well
[22:26] <aadamson> most just plug in their gopro video using an hdmi adapter
[22:26] <Darkside> they all do FM tv though
[22:26] <mfa298> aadamson: technically not legal to use airborne in the UK (at 500mW I'm not sure it's even legal on the ground)
[22:26] <aadamson> even if in the ism band?
[22:26] <Darkside> yp
[22:26] <Darkside> theres power limits
[22:27] <aadamson> I now the RC guys in the UK do FPV so Im sure there are options
[22:27] <mfa298> from memory 10mW on 2.4GHz airborne (possibly 100mW on the ground)
[22:27] <Darkside> a lot of people do it without regard for the laws...
[22:27] <aadamson> well, the fpv guys all use high power from the air, as it's a downlink primarily to google based RX
[22:27] <mfa298> I think most of the FPV people ignore the power limits (hence the technically not legal)
[22:27] <Darkside> it definitely happens here
[22:27] <aadamson> yeah same here on ham bands
[22:28] <Darkside> anyway, you want to b checking the link budgetrs
[22:29] <Darkside> we did a link budget for 23cm FM ATV once, and even with about 30dBi gain on the ground, plus a preamp, the maximum distance for video was about 40km
[22:29] <mfa298> but in general the HAB people try to adhere to the law. Partly as we would cause issues over a much larger areas - FPV is limited to around 150m (from memory) so isn't going to impact that larger an area.

[22:30] <Darkside> .. which sounds like they're seriously breaching the power limits
[22:30] <aadamson> again, perhaps at risk of the law, but I see reports of that all the time.

[23:08] <edusupport> Diddnt know 459Mhz 100mw was legal for FPV in the uk

[23:13] <Willdude> Why is it the only DIY helicopter control projects are normally infrared? Could someone use something like HackRF to control an RC chopper?
[23:14] <fsphil> isn't that a bit extreme
[23:15] <fsphil> like using an Ettus to change channels on a TV

[23:18] <Willdude> Why extreme? It'd be awesome

[23:21] Action: Willdude wants to hack the doorbell we just got
[23:21] <myself> Because pretty soon someone will find a $10 peripheral that can transmit in some useful range, and they'll write a driver for it, and if the work's already been done in a more-open way, it'll port easily
[23:22] <myself> it'd be like using an oscilloscope to decode serial. If you didn't know what the signal was, you could use the 'scope traces to learn how to build a uart. That seems silly, but now imagine that the uart wasn't invented yet.
[23:23] <mikestir_> Willdude: you can probably use an RFM22B to do that
[23:23] <mikestir_> I can turn my boiler off and on with one
[23:23] <mikestir_> most household radio control gear like that has little to no security
[23:24] <Willdude> It's 315 mhz I think
[23:25] <mikestir_> not if it's uk legal it isn't
[23:25] <g0pai_ian_> If the UART wasn't invented yet, you would use the appropriate signal specs to work out the timings, rather than an oscilloscope

[23:31] <Willdude> I listened on my handy but will check on the SDR
