[07:52] <x-f> morning
[07:53] <eroomde> yoyo
[07:54] <natrium42> eroomde: so, i tested the pixel qi screen and give my thumbs up for approval
[07:57] <eroomde> oh awesome
[07:58] <natrium42> first thing i did was wipe windows 7 and install ubuntu
[07:58] daveake (~daveake@daveake.plus.com) joined #highaltitude.
[07:58] <eroomde> it was easier from there right
[07:58] <natrium42> :D
[07:58] <natrium42> but it's so awesome to see the screen with sun shining directly onto it
[07:59] <natrium42> <3
[07:59] <eroomde> can it be retrofitted into something like a thinkpad cf-19?
[08:00] <eroomde> cos then something awesome might be born
[08:00] <natrium42> it has to use the same connector
[08:00] <natrium42> thats the fasyest netbook i found that could fit it
[08:01] <natrium42> tracker works very well
[08:01] <natrium42> in firefox
[08:02] <eroomde> vv interesting
[08:02] <eroomde> it sounds perfect
[08:04] <daveake> Morning
[08:06] <daveake> Pic of my mast up yesterday - http://i.imgur.com/uIhTi.jpg
[08:07] <cuddykid> lovely
[08:07] <cuddykid> all in the name of HAB
[08:07] <daveake> indeed
[08:07] <eroomde> smart!
[08:07] <daveake> That's a very wide-angle lens to get it all in :)
[08:09] <daveake> That side of the house faces east which is handy for when I just put the yagi in the office window (top-right)
[08:11] <daveake> Busy day yesterday!
[08:11] <daveake> navrac's flight somewhat exceeded expectations :)
[08:18] <number10> se you put the radials on this time
[08:18] <daveake> Well spotted :
[08:18] <daveake> :)
[08:19] <number10> does it require two people to setup- takedown
[08:20] <daveake> Probably would if the wind was strong, but no I've done them myself so far
[08:22] <NigelMoby> needs translating but I think Ozzie was picked up at 7am @ 304m 8kph
[08:23] <daveake> The tricky bit is getting the guy ropes tied up so the thing is vertical, and a second person is handy for that, but not essential
[08:24] <number10> I was wondring that - I think Mrs10 doesnt have the same enthusiasm for HAB -
[08:25] <daveake> number10 I think you mentioned that before :D
[08:25] <daveake> NigelMoby Wow, if so then the batteries have lasted rather beyond expectations!
[08:25] <NigelMoby> seems so, prolly got a boost from the morning sun
[08:25] <natrium42> NigelMoby: url?
[08:25] <number10> I dont think she would have been happy having to help take the mast down in the evening yesterday
[08:26] <NigelMoby> he said it in here I can't copy paste, 2 secs...
[08:26] <natrium42> aah
[08:26] <daveake> The last reading on spacenear shows the battery at 1.7V. So that's 0.85V each cell, which is on the very steep part of the discharge curve

[08:27] gonzo_ (~gonzo@109.104.96.45) joined #highaltitude.
[08:27] <NigelMoby> that was at 7am
[08:29] <daveake> number10 taking the mast down is easy on your own
[08:30] Action: daveake tries not to say that you only need your wife's help for the erection part ....
[08:30] <NigelMoby> lol
[08:30] <daveake> and fails

[08:36] <number10> lol , I was going to phrase the question in such a way daveake
[08:39] <fsphil> no more reports then. was still hoping it would keep tracking :)
[08:41] <daveake> If you want to do it single-handed, something like these would help - http://tinyurl.com/725ez3y
[08:42] <SamSilver_> i will say nothing about "dingle-handed"
[08:42] <number10> cheers daveake, I think I need to earn a few brownie points at home
[08:42] <SamSilver_> single handed as well
[08:43] <daveake> :)
[08:43] <daveake> I took care with the phrasing on that :)
[08:43] <number10> :)
[08:43] <daveake> Seriously though, those would make it a lot easier. Getting the mast vertical is the tricky part without help.
[08:44] <daveake> At the mo I have to loosen each knot, tension then re-tie
[08:45] <number10> I can see some hab spend this morning
[08:45] <fsphil> got those brownie points already?
[08:46] <number10> secret hab spend fsphil
[08:46] <daveake> fsphil Yeah, last confirmed position late last night. Incredible flight though.
[08:46] <fsphil> what's mostly annoying is that it may well still be up there, just silent
[08:46] <daveake> Yep
[08:47] <daveake> I think it very likely is
[08:47] <fsphil> your super caps idea is looking a lot more interesting
[08:47] <daveake> fsphil Mast during yesterday's tracking of Ozzie - http://i.imgur.com/uIhTi.jpg
[08:47] <number10> fsphil: which yaesu did say you had
[08:48] <fsphil> number10, 817 857 and 790
[08:48] <fsphil> ah man, I've too many
[08:48] <daveake> greedy :)

[08:48] Action: fsphil runs away
[08:48] <daveake> Got the beard yet?
[08:48] <number10> lol, the Mrs10 would mad if I spent that
[08:48] <UpuWork> morning
[08:49] <fsphil> ah there is no mrs.fsphil :)

[08:49] <daveake> Yeah, I get away with a constant stream of average spends, but I think she'd give me some earasche if I spent £500 on a radio
[08:49] <UpuWork> haha
[08:49] <UpuWork> thats what I do daveake
[08:49] <fsphil> mornin Mr.Work
[08:49] <number10> I think some of those are > 500
[08:49] <daveake> fsphil I suspect there'd be no Mrs Dave either if I did :D
[08:49] <UpuWork> same amount over a long period :)
[08:49] <fsphil> lol
[08:51] <daveake> UpuWork exactly :-).
[08:51] <daveake> Te <cough> work-related <cough> items are easier to slip through
[08:51] Action: daveake pats DSO
[08:52] <number10> at the moment I dont think she realized the reason I was able to track two balloons simultanously
[08:56] <x-f> :)
[08:57] <daveake> :)
[08:57] <gonzo_> one friend use to have huge amounts of 'my' expensive kit on loan, when we were younger. At least that's what he told his mother. The situation hasn't changed since, apart from the excuses are nowgiven to a wife
[08:58] <daveake> lol
[08:58] <daveake> I have a defence against "hmm, that aerial's a bit big isn't it?". I just show her Upu's latest
[08:58] <gonzo_> also used to badge up kit as belonging to the local radio club
[08:58] <UpuWork> lol
[08:58] <UpuWork> fsphil sorry I left your board at home so it won't be posted till tommorrow
[08:59] <fsphil> no worried UpuWork, I won't be able to start building till the weekend anyway
[08:59] <gonzo_> hehe, when asked 'why do you need to put up an aerial that big', reply: ~it doesn't need to be that big, it needs to be much bigger. That's a comprpmise'
[08:59] <daveake> :D
[08:59] <number10> lol
[09:00] <UpuWork> haha
[09:00] <number10> at least with the telescopic its a temporary thing
[09:00] <daveake> Indeed
[09:00] <daveake> I didn't get any grief, just "Oh that's bigger than I thought"
[09:00] <number10> thats the first time you heared that
[09:00] Action: daveake looks round the room waiting for a rude comment
[09:01] <daveake> and there we are :)

[09:20] <Darkside> unlikely to be us

[10:21] <Darkside> i'm probably goign to send my cutdown pcb off for manufacture tomorrow
[10:22] <UpuWork> what happened to that diplexor ?
[10:22] <Darkside> i have the pcbs
[10:22] <Darkside> still waiting on some high-Q components

[11:08] <cuddykid> UpuWork: wow! - :O
[11:09] <cuddykid> how do they work those taxes out?! - maximum should be 20% of say £9 something?
[11:09] <UpuWork> tax was only £3
[11:09] <cuddykid> and £11 to collect?!?!?
[11:09] <UpuWork> but they charge £11 admin
[11:09] <cuddykid> that is ridiculous - I'd be complaining :P
[11:12] <Colin-G8TMV> it's worse than thet, they then charge VAT on the admin fee
[11:14] <cuddykid> UPS have gone down hugely in my estimations
[11:14] <cuddykid> sodding delivery companies!
[11:14] <Darkside> i keep on reading UPS as UPU
[11:14] <UpuWork> not their fault
[11:14] <UpuWork> blame the government
[11:14] <cuddykid> oh yes
[11:15] <cuddykid> don't get me started on the government
[11:15] <cuddykid> I could rant on all day about them
[11:18] <cuddykid> I still don't understand why delivery companies don't implement some sort of notification feature (either push notification, text or email) - for example, when the van is within 5 miles of you and your next (or 2nd) for delivery - send a notification
[11:19] <fsphil> they'd need to spend money
[11:20] <cuddykid> hmm, might not need to - I'm sure every van is equipped with GPS - then it's just a matter of coding, it's not a huge coding job
[11:20] <zyp> they'd save that on not having to do as much second deliveries
[11:20] <fsphil> true
[11:20] <fsphil> one of the carrier companies we deal with showed us their live gps map
[11:21] <fsphil> half the vehicles where out of contact
[11:21] <cuddykid> lol
[11:21] <fsphil> still impressive though
[11:21] <cuddykid> indeed
[11:22] <fsphil> so yea they do have that info
[11:22] <fsphil> most of the time
[11:22] <cuddykid> would be very helpful
[11:22] <cuddykid> almost all vans would be equipped with GPS I would think

[11:30] <cuddykid> UpuWork: what's the one on the right?
[11:30] <navrac> I've got my own that i did upu - without the connector to save weight and laid out to match the antenna

[11:36] <navrac> upu - if you put chokes on the signal lines I would be very interested - and a gnd pad or bit of unmasked gnd about 20mm away from the centre of the ant pin :-)
[11:36] <Darkside> navrac: that was a problem for you?
[11:36] <UpuWork> can do whatever have a chat with me this evening
[11:36] <Darkside> i've for power supply decoupling on my cutdown board, but thats it
[11:38] The-Compiler (compiler@ubuntuusers/supporter/the-compiler) left #highaltitude ("WeeChat 0.3.8-dev").
[11:38] <navrac> yes - the noise floor was the limiting comms factor. It should do -118dBm but on the bench I was getting -110dBm sadly when I assembled ozzie I put the tx right by the arduino and the noise floor fell to about 100dBm
[11:38] <Darkside> hrmm
[11:39] <Darkside> i'm not too fussed if the noise floor is around -100dBm...
[11:39] <Darkside> as we'll be amplifying the uplink
[11:39] <navrac> alright for you with a license....
[11:39] <Darkside> heh
[11:39] <Darkside> i still think 100mW into a 5 element yagi would work well though
[11:40] MoALTz_ (~no@host-92-2-132-147.as43234.net) joined #highaltitude.
[11:40] <navrac> well 50mW into a homebrew 4 ele yagi worked - but that was from ground level pointed largely at random.....
[11:40] <Darkside> heh
[11:41] <Darkside> yeah, i'm thinking 100mW into a decent yagi (which we have with us in our chase cars anyway) would work
[11:41] <navrac> the yagi was a bit bent at that stage as it had ben up and down the mast 3 times, dropped from 20 feet and was made with 2mm brass rods which were all over the place.
[11:42] <navrac> yes it certainly think it would - a nicely matched yagi with the rfm in the connector housing would be ideal
[11:43] <Darkside> mm
[11:43] <Darkside> that means the SPI lines would be long though
[11:43] MoALTz__ (~no@host-92-2-125-141.as43234.net) left irc: Ping timeout: 252 seconds
[11:43] <Darkside> but yeah, i was considering making a 'cutdown boz'
[11:43] <Darkside> box*
[11:43] <navrac> no, I just put a min arduino pro with it so the spi lines were about 25mm
[11:43] <Darkside> mm ok
[11:44] <Darkside> i've got my RFM22B on the opposite side of a PCB to the atmega
[11:44] <navrac> usb doesnt need to be so thick
[11:44] <navrac> good move
[11:44] <navrac> lots of decoup i hope
[11:44] <Darkside> theres a reasonably ground plane between them, but there are traces under the rfm22b
[11:44] <Darkside> well theres only one power supply pin lol
[11:44] <Darkside> and i've got that decoupled
[11:45] <navrac> that should be ok as the bottom of the rfm is largely a groundplane anyway
[11:45] <Darkside> yeah
[11:46] <navrac> I also cut out a bit of copper that went from the chip to the xtal, and put thermal paste between the copper and the bits, then put silicon rubber over the copper and surrounding area. It transferred the heat from the chuip to the xtal quite nicely and lowerd the temperature sensitivity
[11:47] <Darkside> might try that
[11:47] <Darkside> depending on what board configuration i go with, theres either going to be a LDO next to the RFM22B or a switchmode supply
[11:48] <navrac> well i reasoned that especially as it comes down when you want it to be stable, you dont want the higher pressure cold air rushing in - so by sealing it with silicon so theres no air - theres no reason for it to go to it and the silicon acts a agood insulator
[11:48] <Darkside> i'm thinking i might need to use the LDO instead of the switchmode supply, if noise floor issues are a problem
[11:49] MoALTz__ (~no@host-92-2-118-163.as43234.net) joined #highaltitude.
[11:49] <navrac> I think a switchmode should be ok - I got pretty good results when powering the rfm22b off the end of the usb supply which isnt famous for being sqeaky clean
[11:50] <Darkside> ok
[11:50] <navrac> and ozzies boost reg wasnt exactly quiet
[11:50] <Darkside> oh yeah you use a boost reg too
[11:50] <Darkside> shoudl be fine then
[11:50] <Darkside> i wanted to run mine off 2xAAs
[11:50] <Darkside> the same AAs running the cutdown wire too
[11:50] <navrac> that should give you a good days worth then
[11:51] <Darkside> heh
[11:51] <navrac> i only designed for 5 hours.

[12:41] <daveake> gonzo_ That's what I was going to use (I have a tube of them looking for a job :) )
[12:41] <gonzo_> I had a few antenna rotator controlers haging about (g6lvb design) so used one of them as a dev board
[12:42] <gonzo_> can send you the code if you want dave
[12:42] <Darkside> vk5gr: did you notice the typo in the SGV video?
[12:42] <vk5gr> no didnt watch that closely
[12:42] <Laurenceb> dont think the gerbers are online, but thatd make an arduino alternative

[12:43] <Darkside> vk5gr: yeah
[12:44] <Darkside> its not going to go on the horus site until the official release
[12:44] <vk5gr> suspect IGST jumped the gun a little
[12:44] <vk5gr> nor should it
[12:44] <Morseman> Laurenceb a few times
[12:44] <vk5gr> I think I spotted 2 possibly 3 of my shots in there - so looks like my film was helpful to them

[12:46] <vk5gr> good plan - im back at Matts tomorrow night to finish off a few little things
[12:46] <Darkside> ok
[12:46] <vk5gr> now dont you go writing any new code for us to install on Matts truck - we will flatly refuse :-)
[12:46] <Darkside> haha
[12:46] <Darkside> i think we're ok :P
[12:46] <Darkside> he does have to reprogram his test flight computer
[12:46] <Darkside> since i changed the flight computer code around horus 19
[12:46] <vk5gr> we got it working and tracking fine today - just a couple of antennas to add (the window mount) and we are good to go.
[12:47] <vk5gr> the preds are still looking a bit squirrily too - should still be ok - a slightly slower assent rate would help (4ms instead of 5).
[12:47] <Darkside> yeah me and terry discussed that
[12:47] <vk5gr> pretty sure at this stage we will stay out of the lakes -
[12:47] <Darkside> also a larger parachute
[12:47] <Darkside> will drag the flight time out to over 3 hours though
[12:47] <vk5gr> how heavy is the "animal"?
[12:48] <Darkside> terry things we'll be flying under 1kg
[12:48] <Darkside> i'm thinking more like 1.5kg
[12:48] <vk5gr> at least it is between meningie and coonalpyn now instead of all the way down to Keith
[12:48] <vk5gr> really? we are only flying the RTTY payload plus the GoPro/plushy rig wont we?
[12:48] <Darkside> and aprs
[12:48] <vk5gr> (and the radar reflector of course)

[12:49] <vk5gr> i dont think matt was planning opn aprs
[12:49] <Darkside> oh ok
[12:49] <Darkside> it'd be nice :P
[12:49] <Darkside> if its operational
[12:49] <vk5gr> sure - but if weight is an issue then not a great idea, We dont have Matts truck setup to read it at this stage anyway
[12:49] <vk5gr> (other than on the D710)
[12:49] <Darkside> well more weight means slower ascent
[12:49] <Darkside> :P
[12:50] <vk5gr> leave it to matt and terry to decide
[12:51] <Darkside> mm
[12:51] <vk5gr> 15 minutes to go - 300mb source file this time - 5 minutes of film in 1080/25p - giving the PC a headache rendering it down from 24Mbit/s - and on top of that running twixtor in some of the sequences as well (frame estimation plugin for slow motion work)
[12:51] <Darkside> hehe
[12:52] <vk5gr> definitely love twixtor - going to get some great shots out of it on our burst footage methinks
[12:52] <Darkside> cool
[12:52] <vk5gr> fairly easily takes 25fps footage and converts it to say 300fps
[12:53] <vk5gr> can do way higher than that but it depends on the quality of the footage
[12:53] <vk5gr> easier when it is shot in 50p as well
[12:53] <fsphil> 50 fps is nice
[12:54] <vk5gr> thinking about the SGV video - might contact them and see if they are cool with me taking the YouTube copy and uploading to to Vimeo so we can add it to the Project Horus channel there as well after it has been released
[12:54] <fsphil> I saw some 100 fps footage on a 100 fps screen once, pretty amazing
[12:54] <vk5gr> the new gopro hero 2 can do 125fps WVGA in I think 640x480 - feed that through twixtor would produce some very cool slow motion methinks
[12:55] <Darkside> yup
[12:55] <Darkside> i think its 960xsomething
[12:55] <fsphil> oh now that would be brilliant
[12:55] <vk5gr> might be - cant remember the specs now - ive seen one guy on Vimeo play with the 125fps mode and slow it back to 25fps native and it looked pretty awesome.
[12:56] <vk5gr> add twixtor over the top - and with that much source footage it's motion estimation would love it
[12:56] <vk5gr> 8 mins to go - ho hum
[12:59] <vk5gr> here is the HD Hero slomo test http://vimeo.com/31922088
[12:59] <vk5gr> the camera is 848x480
[12:59] <Darkside> ahh
[13:00] <vk5gr> dont know how quick it fills up the card at that frame rate however
[13:00] <Darkside> well hts 1/4 the resolution of 1080p
[13:01] <Darkside> and 4x the frame rate
[13:01] <Darkside> so i'd assime it's be about the same
[13:01] <vk5gr> might not be too bad actually
[13:01] <griffonbot> Received email: navrac "[UKHAS] Re: Brief flight report for Ozzie."

[14:40] <number10> ;)
[14:41] <number10> which one is the typo
[14:41] <navrac> olivier58 was the gentleman who tried to install fldigi as he was the last person with ozzie in range he could hear it but not decode
[14:42] <daveake> Shame, good try though
[14:42] <navrac> just needed one more packet to make 11 hours - 23 secs short...
[14:43] <Colin-G8TMV> navrac: does the payload have contact info on it?
[14:43] <daveake> I wouldn't worry about that - an incredible flight
[14:44] <olivier58> yes i install DL- fldidi
[14:44] <navrac> no it was anonymous in case it crashed into someones greenhouse - actually to be honest there were so many problems during the launch it never got the label put on!
[14:46] <Colin-G8TMV> Oh, so lost then
[14:46] <daveake> Sounds like a stressful launch. On my first one a wire fell off the tracker, and I couldn't get dl-fldigi to decode
[14:47] <fsphil> first launches usually are
[14:47] <fsphil> I was still writing software up until a few minutes before launch
[14:47] <daveake> :D
[14:48] <daveake> I made some mods 2 days before, and that didn't work out well ...
[14:48] <Colin-G8TMV> I'm actually worried about the number of launch problems you guys have - I used to fly free-flight model aeroplanes and we always took things slowly before a launch to make sure nothing was forgotton
[14:48] <Colin-G8TMV> daveake: Golden rule - if it works don't mess with it! ;)
[14:49] <fsphil> subsequent launches usually run a bit smoother Colin-G8TMV
[14:50] <daveake> I think that first launch there are so many things to think about that you haven't done before, you've got a very high chance that something won't go to plan despite the planning and testing
[14:50] <Randomskk> I think some of it can be down to having to launch in a particular narrow window that's organised weeks/months in advance
[14:50] <Colin-G8TMV> fsphil: lets hope so
[14:50] <Randomskk> and yea, there are plenty of moving pieces involved :P
[14:50] <Colin-G8TMV> Randomskk: it's better not to launch than to launch in a hurry
[14:50] <Randomskk> oh, I agree
[14:50] <Randomskk> but that doesn't stop it being a factor
[14:51] chris_99 (~chris_99@unaffiliated/chris-99/x-3062929) left irc: Ping timeout: 240 seconds
[14:51] <Randomskk> you make your judgement calls as the situation requires
[14:51] <olivier58> the signal this ballon is on mode FM or USB ?
[14:51] <daveake> USB
[14:52] <Colin-G8TMV> I'm always surprised at how much "payload building" happens at the launch site. Why? surely things should be assembeled and tested well before that
[14:53] <Randomskk> a lot of things can't be finalised until the last minute
[14:53] <Randomskk> mostly involving rigging
[14:54] <Colin-G8TMV> Randomskk: why?
[14:54] <Randomskk> well, I say "can't"
[14:54] <Randomskk> mostly they're just much easier and more convenient to do then
[14:54] <Randomskk> and it's not a massive issue
[14:54] <Randomskk> but for instance you may find you suddenly don't get GPS lock, your on/off switch might be inside a box that is sealed shut before launch, your batteries are embedded inside but need charging the day before, etc
[14:54] <Colin-G8TMV> you could turn up with a built payload and then line and parachute wrapped around a piece of cardboard to stop it tangling
[14:54] <Randomskk> unexpected things go wrong and require fixing
[14:55] <Randomskk> you could, but then you've had to get all that set up and it's not usually a thing that goes wrong
[14:55] <Randomskk> there's not really any reason to set up rigging before hand, assuming you don't have to really rush the launch
[14:55] <Colin-G8TMV> If you don't get GPS lock then something is wrong and you should not launch
[14:55] <Randomskk> I disagree -- it might be something as simple as you forgot to plug a GPS antenna in, or another payload launching on the same day is causing interference
[14:56] <Randomskk> it could be a problem you can quickly and easily fix in the field, is what I'm saying
[14:56] nigelvh (45a4a77e@gateway/web/freenode/ip.69.164.167.126) joined #highaltitude.
[14:56] <daveake> What I do with my camera payloads, is turn up with the box, with short lines around going to a metal ring. From there to the chute and balloon gets done at the launch site.
[14:56] <Colin-G8TMV> That's my whole point "unexpected" things should (a) not happen or (b) should cause the launch to be canceled
[14:56] <Randomskk> obviously the situation context comes into play -- if we were building nuclear reactors then risk tolerance is much lower
[14:56] <daveake> Doesn't take long at all.
[14:56] <Randomskk> but there's no reason to cancel a launch if you can identiy and fix a problem
[14:56] <daveake> Lid goes on once the thing has lock and the cameras are started.
[14:56] <daveake> Lif + gaffer tape takes very little time
[14:56] <daveake> d
[14:57] <Randomskk> daveake: and then you rig it to the parachute, right?
[14:57] <Randomskk> and then the parachute to the balloon?
[14:57] <Randomskk> there's limits to how much is worthwhile preparing in advance
[14:57] <daveake> Yes, think I said that :-). Rig to chute and balloon at the launch site
[14:57] <Colin-G8TMV> daveake: if that is designed as part of the procedure then it's ok - it's when it happens because something got forgotten that it's a problem
[14:58] <Randomskk> Colin-G8TMV: I think it really depends on the situational risks involved
[14:58] <Randomskk> in many cases I'd argue it's better to have lots of launches that don't all go quite perfectly than only have ever made one launch
[14:58] <Randomskk> you can gain a lot of experience either way
[14:58] <fsphil> my only technical problem so far was the faulty antenna, and there was no way to tell that it was broke before launch
[14:58] <daveake> Well really there's very little in it between having the full line made up and run round cardboard tubes to stop it knotting (because it will otherwise), and just measuring the line and tying off on site
[14:58] <Randomskk> if you can only afford to launch once, then yes, spend a lot of time putting a lot of work into reliabiltiy and test the hell out of it
[14:59] <Randomskk> afford in the financial/time/risk sense
[14:59] <Colin-G8TMV> fsphil: how can you not tell your antenna was broken? Don't you do a signal strength test before launch?
[15:00] <Randomskk> Colin-G8TMV: the difference in range between a box on your desk and a box miles in the sky is usually a pretty important factor
[15:00] <Randomskk> wombat was S9+60dB on the ground
[15:00] <Randomskk> but once we launched it, it got maybe one or two decodes
[15:00] <fsphil> Colin-G8TMV, decoded perfectly until it got to about 20km away
[15:00] <fsphil> I actually think it broke after launch
[15:00] <Colin-G8TMV> fsphil: and what was wrong with it - have you found out?
[15:00] <fsphil> never recovered
[15:01] <fsphil> still in a yorkshire field :)
[15:01] <Colin-G8TMV> Ah, sorry I meant wombat
[15:01] <Colin-G8TMV> fsphil: Ah, the one on the army range?
[15:01] <Randomskk> not yet, I was 36 hours without sleep by the time we got back yesterday ;) it's in the lab for a post-mortem later today or tomorrow
[15:01] <fsphil> Colin-G8TMV, possibly - depends on which side of the road it landed on
[15:02] <Randomskk> I suspect the VCO in the ADF wasn't being kept very well in tune by the pll, so it was putting out signal all over the place and masking the actual rtty
[15:02] <fsphil> we only know to within a few km of where it landed
[15:02] <Randomskk> but we'll see
[15:02] <Colin-G8TMV> Randomskk: thats another pretty important experimenting rule "never pull an allnighter just to get it ready"
[15:02] <Randomskk> well
[15:02] <fsphil> that's my rule #1 -- so far I've always broken it
[15:02] <Randomskk> Colin-G8TMV: again I think that's really situationally dependent
[15:02] <LazyLeopard> Heh!
[15:03] <Randomskk> we've had projects that must work -- sending up high risk/high value items
[15:03] <daveake> Actually, I get worried when I'm ready days before. I wonder what I missed :)
[15:03] <Randomskk> and yes, in those cases we have a /lot/ of testing, redundant systems, lots of checks, small-scale launches before the main thing, etc
[15:03] <Randomskk> but in other cases -- this one -- there were four separate systems to track the payload, and it malfunctioning introduced no new risk
[15:03] <Randomskk> but we had it transmitting a signal and wanted to see how it performed
[15:03] <LazyLeopard> Any more news from the Brum lot who forgot to plug their GPS in?
[15:03] <Randomskk> I really don't think we should have not put wombat in the box, or aborted the whole launch
[15:04] <Randomskk> but I mean, it's a point I'm happy to talk about, because I don't think it's a black and white issue
[15:05] <fsphil> the willingness for people to experiment a bit is what makes all this interesting. when I started people where still using big bulky flight computers, now they're teeny tiny things
[15:05] <Colin-G8TMV> I learned never to rush things when I was flying light aircraft - it's really important to get it right when it's your own neck on the line
[15:05] <daveake> Indeed Randomskk. My last flight I had a test tracker which I only started building a week before launch, but it was attached to a known working well-tested tracker so not great problem if it didn't work. Which it did anyway :)
[15:05] <Randomskk> Colin-G8TMV: to be sure! they're fast and high risk
[15:05] <Randomskk> and if you mess up you can cut people open
[15:05] <Randomskk> HABs are relatively slow, low risk and if I mess up I might lose the box
[15:05] <Randomskk> (with a constant risk every launch of landing on something/somehwere bad -- but the best payload won't help that)
[15:06] <Randomskk> (we do have stringent regulations on when and how we do the launch -- our actual launch procedures are good)
[15:06] <Colin-G8TMV> Randomskk: well... unless you wrap the payload in a duvet
[15:06] <Randomskk> (but when it comes to what payload we put in, we can afford to experiment)
[15:06] <daveake> LaztLeopard - Don't think so. Ping cuddykid as he was in SMS conversation with them
[15:06] <Randomskk> Colin-G8TMV: it's a lightweight foam box, with a foamy antenna made of flexible wire, under a sufficiently large parachute, with a predicted landing trajectory that avoids airports, flight paths and cities
[15:07] <Randomskk> like I said, we have procedures for launch to keep that constant risk safe, and it has nothing to do with the payload systems
[15:07] <Randomskk> beyond basics like "is this still a legal transmitter", which in any case it was
[15:07] <Colin-G8TMV> actually thinking of Antennas, the Ozzie1 antenna looked like rigid wire - I hope it didn't stab anything when it came down
[15:08] <Colin-G8TMV> Randomskk: from a tracking point of view I think the main imporvement in payloads would be frequency stability
[15:08] chris_99 (~chris_99@unaffiliated/chris-99/x-3062929) joined #highaltitude.
[15:08] <Randomskk> ironically a thing I was trying to work on here ;)
[15:08] <Randomskk> though not with this launch...
[15:09] <fsphil> stability would be brilliant
[15:09] <Colin-G8TMV> Apex moved several KHz yesterday
[15:09] <Randomskk> had wombat worked okay, it can change its transmit frequency really readily, which means it can temperature compensate itself
[15:09] <Randomskk> apex's radio couldn't be easily retuned
[15:09] <fsphil> Brum's was the worst I ever saw
[15:09] <daveake> Yep
[15:09] <daveake> Even worse than Buzz1
[15:09] <Randomskk> wombat in theory could have been dead precise by compensating itself for temperature drift over a huge range
[15:09] <Colin-G8TMV> Never heard the Brum one
[15:09] <fsphil> they must have had no insulation on the radio
[15:09] <Randomskk> Colin-G8TMV: again it's one of the things we're experimenting with
[15:09] <daveake> Buzz1 was a bit leaky
[15:10] <Colin-G8TMV> Also - I remember someone talking about dl-fldigi being able to re-tune the Rx to counteract drift - did that ever happen?
[15:10] <Randomskk> though to be honest I think frequency stability is only one of a number of things that could be improved for trackers
[15:10] <Randomskk> Colin-G8TMV: it's been able to for a while
[15:10] <Randomskk> so long as your radio is controllable by dl-fldigi to start with
[15:10] <fsphil> yea
[15:11] <fsphil> there was a bug in a previous version that meant it stopped tracking after a while, but the newer versions all work fine
[15:11] <Colin-G8TMV> Randomskk: oh, I must have missed that and I do have cat control for my 817
[15:11] <fsphil> I was able to setup my home radio to receive it, and leave it unattended
[15:11] <navrac> colin-G8TMV: the aerial looks rigid in the pictures but actually it was very thin wire - it would definatly bend rather than stab some one - which is why in the pics it isnt very straight - it actually deforms under its own weight
[15:11] Action: Colin-G8TMV wonders if he is using a new enough version
[15:12] <fsphil> check in the configuration dialog, there's an option for it
[15:12] <fsphil> it's not enabled by default
[15:12] <Colin-G8TMV> will do when I get home this evening
[15:13] <Colin-G8TMV> Yesterday was the first time I did any tracking since moving house - it was really nice to have a real antenna on a real outside mast
[15:13] <fsphil> it is :)
[15:14] <Colin-G8TMV> house is amout 20m asl and tri-band colinear on a sCAM-12
[15:15] <Colin-G8TMV> unfortunately the ground rises to the south of the house, but takeoff in other directions is good
[15:15] <navrac> ,y house is 70mASL - trouble is the hill in front of it is a lot lot more
[15:15] <navrac> so i habve a blindspot to the SE. Which is exactly where the payload went
[15:16] <Colin-G8TMV> when I get some Round Tuits I'll get the beams on the mast - I've got a really old 21 Ele Tonna for 70cms
[15:16] <gonzo_> I'm in a hole in the ground, 60ft mast req just to be level with the surrounding land. But no probs for satellite or balloon tracking
[15:17] <fsphil> olivier58, what time did the balloon signal stop?
[15:17] <navrac> the local amateur who helped keep an eye on the tx levels whilst i was launching offered me a 60 foot mast - i said it wouldnt get passed planning - he said well i got permission - and i explained that the first step of the planning is persuading the wife
[15:18] <daveake> lol
[15:18] <navrac> i did show her - but the gain from the extra height was less than the cable loss from the 300m feeded which was as close as she will accept to the house
[15:19] <Colin-G8TMV> navrac: planning is one of the reasons I have the SCAM-12 - it's a "tempory" structure and doesn't need any permissions. It also is very quick to raise and lower
[15:19] <SpeedEvil> navrac: hardline, or a LNA on the mast.
[15:19] <SpeedEvil> navrac: Or indeed a remote radio.
[15:19] <Colin-G8TMV> navrac: or a shack 300m from the house
[15:20] <navrac> i did think of that - but i have to say the only suitable spot for it would be an eyesore for our neighbours. So we've agreed to move instead
[15:20] <Laurenceb> or just do a fritzl
[15:21] <cuddykid> still no post here - I think all my HAB packages have annoyed the postie

[15:24] <cuddykid> lol
[15:24] <W0OTM> The idea being, a landing site is pre-determined, and the point is to launch your balloon from wherever each team decides is the best location to land closest to the Landing Zone
[15:24] <jonsowman> UpuWork: that was a fantastic top gear episode
[15:25] <W0OTM> cuddykid: Yes, we have launches planned this summer to continue BallooMerang progress

[15:25] <cuddykid> W0TOM: brilliant, I look forward to seeing the results. My glider is being made currently (delta wing design) - and APM2 should be arriving any day
[15:26] <W0OTM> APM = failure

[15:26] <cuddykid> oh no

[18:11] <W0OTM> So I want to fly a crossband repeater in my next payload. I have APRS 144.39. Would it be best to use 2M (147.500) as the uplink or downlink on the repeater?
[18:11] <nobby_noGPS> Is there anybody about who could give me some pointers re gps & arduino?
[18:11] <W0OTM> When the APRS beacons its going to interfere, but it is less likey to effect performance if I use the 2M as the downlink
[18:12] <W0OTM> UHF for uplink
[18:18] <Hibby> nobby_noGPS: potentially.

[18:24] <jonsowman> is it connected to the hardware uart on the arduino?

[18:29] <jonsowman> nigelvh: 3V3 signalling
[18:29] Action: Hibby faintly remembers ublox with newsoftserial
[18:29] <nigelvh> jonsowman, not voltages. Rather, whether a high means a binary 1 or 0, TTL and RS232 have them swapped.
[18:30] <eroomde> true dat
[18:30] <jonsowman> oh i see
[18:31] <nigelvh> Like I said, I don't know anything about the ublox, but there are a good number of GPS modules that do TTL voltages, but RS232 levels.
[18:31] <jonsowman> i've not come across one, but then i've only ever used 3 GPSes really
[18:32] <jonsowman> i wonder if tinygps has any scope for dealing with that
[18:32] <nigelvh> The Garmin 15-L is one that I've used. The High altitude GPS from Argent also has a set of lines for RS232 levels (in addition to a TTL set of lines)
[18:32] <jonsowman> how odd
[18:32] <nigelvh> I'm not sure the hardware uart on the atmels can do inverted signaling.
[18:32] <nigelvh> I haven't found it in the datasheet.
[18:32] <jonsowman> no but tinygps uses software serial
[18:33] <nigelvh> I have either used a hex inverter, or software serial, which CAN do inverted signalling
[18:33] <nigelvh> Tinygps doesn't care. Tinygps can use any serial source you like
[18:33] <nigelvh> It is COMMONLY paired with software serial.
[18:33] <jonsowman> it's been forever since i've used it
[18:34] <jonsowman> been forever since i've used an arduino for that matter
[18:35] <nigelvh> What I do most the time is etch my own boards, then stick an arduino compatible chip on there, mostly because I like the arduino bootloader.
[18:35] <jonsowman> I prefer raw AVRs really
[18:36] <nigelvh> I may move that direction. But for a long time I didn't have an ICSP programmer
[18:36] <nigelvh> Now I do, and I may move that direction.
[18:36] <jonsowman> well you can use an Arduino as an ICSP programmer if you really want
[18:36] <jonsowman> but a 'real' one is kind of nicer
[18:37] <nigelvh> I etched a board and put an 328p on it and attached a 6pin ICSP cable to it, USB on the other side. works pretty good.
[18:37] <W0OTM> nigelvh: the downlink wont interfere too badly with the APRS transmissions?
[18:38] <nigelvh> Shouldn't
[18:38] <W0OTM> ok
[18:38] <nigelvh> Obviously test it, but two xmitters in proximity should be fine.
[18:38] <W0OTM> ok, great
[18:38] <W0OTM> so uplink on 445.000 and dwn on 147.500 and APRS 144.39
[18:39] <nigelvh> On our balloons, we have a 434 data downlink, and a 427 video downlink and they work great.
[18:39] <W0OTM> excelent
[18:39] <W0OTM> thanks
[18:41] <nigelvh> Do test it a good bit though. I tried a cross band repeater once, (2m uplink) and it was kinda a last minute addition so it wasn't really tested, and lots of RF got into the cables connecting the reciever and xmitter, and so nothing actually got through the repeater.

[19:14] <navrac_> good evening - how are you doing
[19:15] <jcoxon> good thanks
[19:16] <navrac_> I'm busy looking at power saving techniques!
[19:16] <jcoxon> haha
[19:17] <nigelvh> Power switch off. Uses an amazingly low 0nA
[19:17] <navrac_> and better power sources - but I'm struggling to find anything with a better density/temp performance
[19:17] <jcoxon> navrac_, its a difficult balance
[19:18] <jcoxon> as people get annoyed when there are gaps in the signal
[19:18] <jcoxon> makes tracking much harder
[19:18] <jcoxon> i've done extensive tests
[19:18] <Bob_G8NSV> hi navrac
[19:18] <fsphil> shame we can't control power to the ntx2
[19:18] <navrac_> I think the only saving is to have a battery backup on the gps and shut it down
[19:18] <navrac_> hi
[19:18] <fsphil> have it transmit a low power carrier
[19:18] <jcoxon> power saving is inversely proportional to tracker happiness
[19:18] <NigeyS> lol
[19:18] <navrac_> yes, sadly

[19:19] <Bob_G8NSV> I have spent today thinking about power supplies
[19:19] <fsphil> or just transmit a message
[19:19] <navrac_> or change it to 'moved a bit but not much'
[19:19] <navrac_> any good thoughts?
[19:20] <jcoxon> well gaps between tx's
[19:20] <jcoxon> hellschrieber uses less power
[19:20] <jcoxon> as its duty is low
[19:20] <jcoxon> compared to rtty which is 100%
[19:20] <Bob_G8NSV> lightweight solar panels? might not power the whole thing but take some of the strain off the batteries?
[19:20] <navrac_> well yes thats true
[19:20] <navrac_> OOK
[19:20] <Bob_G8NSV> I thought of only keying the tx in bursts like packet?
[19:21] <Bob_G8NSV> but maybe stability is an issue?
[19:21] <jcoxon> yes that is a big issue
[19:21] <jcoxon> it drifts between setups
[19:22] <Bob_G8NSV> that seems a major problem with anything other than custom hardware then?
[19:22] <G0DJA> Would a mode like OLIVIA be better than RTTY on power use?
[19:22] <SpeedEvil> It's largely irrelevant.
[19:23] <G0DJA> Or would that be more complicated than a few resistors on 2 pins?
[19:23] <Bob_G8NSV> It may with a proper SSB TX but prob no difference with a constant carrier
[19:23] <SpeedEvil> The RF module uses ~20mW - shrinking this to ~10mW isn't going to help much
[19:23] <SpeedEvil> And it's way more complex.
[19:24] <Bob_G8NSV> It seems better temp control so the carrier can be dropped between transmissions
[19:27] <Bob_G8NSV> there are some thin film PV materials manufactured, dont know about cost, wonder what the cheap things they use in phone chargers weigh if you strip all the case and protective glass off the front?
[19:27] <Bob_G8NSV> I think some of those give 5 or 6V at around half a watt, more than enough?
[19:28] <MrCraig> off topic: has anyone here ever had the problem that 'some' ctrl+key combinations stop working? (ubuntu but same under xp) if so please let me know how you fixed that.

[19:33] <Bob_G8NSV> I got some glass backed ones a few years ago, too heavy tho
[19:33] <SpeedEvil> A boost converter to go from 0.5->4 or so is trivial - especially if you already have a few microamps at 4V available
[19:33] <Bob_G8NSV> no need you series the cells up till you get 4 or 5V
[19:34] <SpeedEvil> That's an alternative.
[19:34] <nigelvh> The issue comes down to space and weight. If you add full cells, they'll be too large, small chunks of cells won't put out much power.
[19:35] Action: SpeedEvil looks at his 2kWp of cells.
[19:35] <SpeedEvil> One dangling cell that you accept will get destroyed on landing isn't a bad balance.

[20:07] <Bob_G8NSV> Its looking viable then if the surgery can be peformed to produce custom arrays
[20:07] <Laurenceb_> or whatever its called
[20:07] <SpeedEvil> Remember, a randomly oriented vertical cell will only put out perhaps a quarter of its sticker wattge on average
[20:08] <Bob_G8NSV> you would have to have a hexagonal type of array like used on the old fashioned satellites
[20:09] <Bob_G8NSV> would be fine with a full sized balloon but real fun to achieve with a pico!
[20:10] <nobby_noGPS> does a gps spew out garbage when no signal or just blank sentences?
[20:10] <SpeedEvil> No, you don't.
[20:10] <SpeedEvil> You just need one panel, and charge when it's facing the sun, in pulses.
[20:11] <Bob_G8NSV> if you could power the payload totally during daylight and run on batteries only at night at the height of summer you may be able to power a floating payload for 24-48 hours (assuming it flaoted this long)
[20:12] <Bob_G8NSV> you could use the pulses to charge a big capacitor maybe, like those backup caps?
[20:13] <Laurenceb_> theres this think called a rechargeable battery
[20:13] <Bob_G8NSV> yes but they are heavy
[20:13] <Laurenceb_> not necessarily
[20:13] <Bob_G8NSV> true but what about low temp? most are not good at that
[20:14] <x-f> nobby_noGPS, it outputs normal NMEA sentences
[20:15] <x-f> depends on the GPS, it may be old information (when it had fix), may be garbage
[20:15] <Bob_G8NSV> I know lipo ones dont work well in the cold nor do nicads and nimh

[20:22] <Upu> softserial ?
[20:23] <nobby_noGPS> Yep - I know that much but don't ask me anything difficuly(!) :) as I a newbie..
[20:23] <Upu> What arduino are you using ?
[20:23] <nobby_noGPS> Mega 2560
[20:23] <Upu> thats got hardware UARTS ?
[20:24] <Upu> lots of them ?
[20:24] <daveake> Plenty
[20:24] <NigeyS> 4
[20:24] <nobby_noGPS> But if I need to I can pinch my 15 year old's Uno
[20:24] <Upu> whats the GPS ? and is it 5V "ok" ?
[20:25] <Upu> Mega should be find as long as you have the GPS plugged into one of the hardware UARTS
[20:25] <nobby_noGPS> It a ublox max 6q via Sparkun frun TTL convertor - Maybe I have no CLUE!
[20:25] <cuddykid> no then - needs 3v3 I think
[20:25] <cuddykid> Upu's board to the rescue
[20:26] <Upu> its a 3.3v module
[20:26] <Upu> how are you powering it ?
[20:26] <nobby_noGPS> Yep power is 3.3 as is logic after TTL convertor
[20:26] <nobby_noGPS> Power - Probably on raw ac - it from the Arduino via a smoothed voltage regulator
[20:26] <Upu> would that be the logic that can supply 50mA and the GPS that can take up to 100mA under acquisition ?
[20:27] <Upu> possible power issue ?
[20:27] <nobby_noGPS> DHow much can the Arduino spit out at 5v - I'll go looking
[20:27] <Upu> more than that
[20:27] <Upu> but the ublox is 3.3v so be careful
[20:28] Action: Hibby had the issue of the arduino not providing enough current to run a ublox gps
[20:28] <Upu> is the MAX on a breakout board of some sort ?
[20:28] <nobby_noGPS> I definately have 3.3v powering and 3.3v logic on the gps side and 5'ish logib on the arduino side
[20:29] <nobby_noGPS> Yup - I think I got it from a rather suspect person...
[20:29] <Upu> oh you have one of mine ?
[20:29] <nobby_noGPS> Yes - but the blame is all mine as I haven't got a clue...
[20:29] <Upu> lol
[20:30] <Upu> ok well try this
[20:30] <Upu> make a 3.3v power
[20:30] <Upu> from something not the Arduino
[20:30] <Upu> connect GND to GND
[20:30] <Upu> on Arduino and GPS
[20:30] <Upu> connect the 3.3v to the breakout
[20:31] <Upu> then connect TX on the GPS ONLY to an RX pin on the Arduino
[20:31] <Upu> and see if you get anything
[20:31] <Upu> do you have any 3.3v regulators lying about ? :)
[20:31] <nobby_noGPS> panic .. I'll give it q go - may be a while... Would a 9v bat be ok via voltage reg to power it
[20:32] <Upu> depends on the regulator
[20:32] <Upu> some have limits on the input voltage
[20:32] <Upu> got a bench PSU ?
[20:32] <Upu> no need to panic you've not knackered it as its giving something out
[20:32] <nobby_noGPS> 30amp 12v - overkill !
[20:32] <Upu> whats your call sign ? :)
[20:32] <Hibby> You can never have too much power.
[20:33] <nobby_noGPS> Arghh to obvios
[20:33] <nobby_noGPS> Phone back shortly
[20:34] <Upu> Don't worry about being a "noob" trust me we've all been there
[20:34] <fsphil-laptop> me, several times
[20:34] <Upu> apart from Laurenceb and Darkside who I'm sure have probably forgotten more than I'll ever know
[20:35] <Upu> I've left my Arduino at work or I'd set something up

[20:39] <Upu> you're Jon :)

[20:39] <Upu> indeed

[20:39] <nobby_noGPS> common as.
[20:39] <Upu> anyway
[20:40] <Upu> Ok so what port on the Arduino Mega is the GPS TX plugged into ?
[20:40] <nobby_noGPS> one - only got one line connected
[20:41] <Upu> port 1 ?
[20:41] <nobby_noGPS> +have an ld33v regulator
[20:42] <Upu> go knock up a PSU on a breadboard
[20:42] <Upu> lets get a stable 3.3v
[20:43] <Upu> btw the GPS TXD should go into pin 0 on the Mega
[20:43] <Upu> thats Digital pin0 RX0
[20:46] <nobby_noGPS> working on it
[20:46] <Upu> no probs
[20:46] <Hibby> comment your code!
[20:46] <Upu> lol
[20:46] Action: Hibby has just discovered the value of it!
[20:46] <Upu> [20:45] * Hibby looks back and thanks past hibby for commenting code.
[20:46] <Upu> [20:45] <Hibby> // PWM period = 125 KHz / 625 = 200 Hz
[20:47] <nobby_noGPS> yup - it's all crap
[20:47] <Hibby> that's the one!
[20:47] <Upu> off to make a brew
[20:47] <nigelvh> I haven't been reading the whole thing, but remember that the 3.3v on arduino boards is provided by the FTDI and can't source much current
[20:47] <nigelvh> Probably not enough to run a GPS.
[20:47] <daveake> Yeah, Upu's covered that one
[20:48] <Hibby> NigeyS: I had that issue. Spent ages bouncing my head off a wall
[20:48] <Hibby> even more depressing, I had an E(M)E degree by that point.
[20:48] <daveake> :D
[20:50] <daveake> Does it help if I tell you that I once needed 12V to run a TV, so I took an unsmoothed DC supply + separate smoothing unit, and instead of setting to about 8.5V (*1.4 = 12V) I set it to 18.5V (12 * 1.4) ?
[20:51] <Hibby> beautiful.
[20:51] <daveake> TV worked fine for a few minutes then some magic smoke escaped
[20:51] <daveake> After cooling down it did actually work again, amazingly. Russian engineering :D
[20:51] <Hibby> ah, that damned black smoke
[20:52] <Upu> "magic smoke" :)
[20:52] <fsphil-laptop> they must have put extra magic smoke into it
[20:52] <fsphil-laptop> for just that case
[20:52] <daveake> Exactly :)
[20:52] <Hibby> lol
[20:52] <daveake> Well the -ve line was a red wire, so I guess they were protecting themselves
[20:53] <daveake> I was at Uni at the time so I did have the excuse of not yet having an Electronics degree
[20:53] <fsphil-laptop> I've cunningly still got that excuse

[21:00] <Upu> sure fsphil made one the other day
[21:00] <fsphil-laptop> none of my jokes are bad
[21:00] <Upu> right so question
[21:00] <Upu> http://uk.farnell.com/on-semiconductor/ncp1402sn33t1g/ic-voltage-regulator/dp/1703414
[21:00] <daveake> I thought you meant 4 just by me :p
[21:00] <Upu> why doesn't that regulate when it gets past supply voltage of 3.3
[21:00] <Upu> it boosts up until then
[21:01] <fsphil-laptop> you can't boost down?
[21:01] <Upu> well I understand you boost when the the supply < 3.3 and you regulate when its > 3.3v
[21:01] <Upu> but that just boosts
[21:01] <Upu> and it sure says "regulator" in the description
[21:01] <daveake> Over on the right of that page there's a "Live Tech Support" button :p
[21:01] <Upu> hmm
[21:02] <Upu> you know thats going to be a waste of 10 mins
[21:02] <daveake> yep
[21:02] <fsphil-laptop> there is an IC that works both ways
[21:02] <Upu> linky mclinky of the clan mclink pls
[21:02] <fsphil-laptop> it's for getting 5V from 4x AAs
[21:02] <fsphil-laptop> googling now
[21:02] <Upu> does it boost though ?
[21:02] <fsphil-laptop> yea
[21:03] <fsphil-laptop> maxim make it, that's all I remember
[21:03] <nigelvh> First sentence of the datasheet. The NCP1402 series are monolithic micropower step-up DC to DC converter that are specially designed for powering portable equipment from one or two cell battery packs.
[21:03] <nigelvh> Boost only
[21:04] <Upu> yeah
[21:04] <Upu> thats what I suspected
[21:04] <Upu> the Farnell page is misleading

[21:05] <fsphil-laptop> you'd never need to regulate from a single cell?
[21:05] <Upu> :)
[21:05] <fsphil-laptop> always boost?
[21:06] <Upu> I was trying to make a board that you can run from 1 cell or connect up 4 etc for long duration
[21:06] <Upu> can wire them in parallel I guess ?
[21:07] <daveake> These things are aimed at Li-Ion cells
[21:07] <daveake> So they don't go down as low as we'd like
[21:08] <nigelvh> You could certainly wire them in parallel
[21:08] <daveake> For long duration 2 AAs would be fine
[21:08] <nigelvh> That is in fact what you would want to do to increase operating time.

[21:13] <fsphil-laptop> very likely the ocean
[21:14] <Elmar_PD3EM> probably but the last predictions back to the uk where amazing
[21:14] <fsphil-laptop> yea!
[21:14] <fsphil-laptop> and it was following it perfectly
[21:14] <fsphil-laptop> we could almost do a sample return mission
[21:15] <Elmar_PD3EM> a balloomerang ;-)

[21:19] <Elmar_PD3EM> with the balloon?
[21:19] <navrac_> I just concentrated on keeping the weight to about 30g as it meant that there was enough capacity in the balloon to expand
[21:19] <navrac_> no sadly I didnt - camera was on the side but in the panic i forgot to grab it
[21:20] <Elmar_PD3EM> i can imagine that....

[21:24] <Upu> float time :)
[21:24] <Elmar_PD3EM> haha great Upu!!
[21:24] <navrac_> andsay which one floated - and went for a payload of 1/4 of it as i reckon 1 balloon would work better
[21:25] <Upu> seemed to work
[21:26] <Upu> you cleared me out of Sarantels anyway had to order some more today
[21:26] <Elmar_PD3EM> looking forward to do some testing with the Arduino Uno and pro mini :-)
[21:27] <navrac_> so ozzie2 is a similar principle but with much better power conservation and some extra interesting bits
[21:27] <Elmar_PD3EM> so the sarantels are going fast upu
[21:27] <Upu> when is that going up ?

[21:28] <Upu> ok
[21:28] <Upu> its just a boost isn't it ?
[21:28] <navrac_> yep
[21:28] <Upu> silly Farnell page
[21:28] <navrac_> it did regulate a bit when i gave it 5 volts
[21:29] <Upu> not a major issue but I'll have to redo one of the PCB's
[21:29] <Upu> still all testing
[21:29] <Upu> be fine for the Pico board
[21:29] <daveake> I think I've discovered a new force of nature. It's like gravity, but the smaller the component the more it's attracted to the floor.
[21:29] <navrac_> but only till i noticed it was powered at 5v
[21:29] <navrac_> and acccording to how long the carpet pile is and its similarity to the colour of the carpet
[21:29] <Upu> :)
[21:30] <daveake> navrac_ "It did regulated a bit" ... I tried earlier with a 1400 (baby version of the 1402) and it just gave a schottky diode drop when "stepping down"

[21:32] <andrew_apex> i'm helping troubleshoot a HAB payload with a NiM2 transmitte - we're seeing 5 lines on fldigi - any ideas?
[21:32] <andrew_apex> (equally spaced lines)
[21:32] <andrew_apex> it isn't an issue at lower baud rates
[21:32] <daveake> Well my Sparkfun step-up board survived the change and my fubled soldering
[21:33] <daveake> fumbled
[21:33] <navrac_> could be becaue i was taking too muck load as it was running at 5v
[21:33] <daveake> Yeah, no load you get o/p=i/p above 3.3V
[21:34] <daveake> If you look at the circuit there's a DC path from Vin to Vout with an inductor and schottky diode between
[21:34] <Upu> At 50 baud Andrew ?
[21:34] <navrac_> yerah just looked and saw that
[21:34] <andrew_apex> it's only a real problem at 300 baud
[21:34] <andrew_apex> only slightly there at 50
[21:34] <andrew_apex> the tx line spikes up to 3v3 for 25uS when switching from space to mark and down to 0v for 25uS when going mark to space - is that the issue?
[21:34] <fsphil-laptop> never seen that before
[21:34] <jonsowman> andrew_apex: sounds suspicious
[21:35] <fsphil-laptop> how is it wired up?
[21:35] <jonsowman> why don't you bench power supply on the NiM2 TXD pin and check
[21:35] <daveake> 2 * Lithium = 3.64V initially (and briefly) but that shouldn't give 3.3V logic much to worry about
[21:35] <andrew_apex> can do
[21:35] <andrew_apex> wired as the standard two pins, resistor mixing
[21:35] <jonsowman> andrew_apex: what's driving it?
[21:35] <andrew_apex> gadgeteer...
[21:36] <jonsowman> and it's switching the two pins as close together as possible?
[21:36] <jonsowman> can you get a scope probe on the two lines from the gadgeteer
[21:36] <andrew_apex> seems to be at the same time scoping the pins
[21:36] <jonsowman> hmm ok

[22:19] <fsphil-laptop> they're too bright to be planets
[22:19] <Upu> rest of it was the BBC's
[22:19] <NigeyS> ill check stellarium, theyre on / near the ecliptic, so probably not noise
[22:19] <Upu> look just up to the left of those
