[00:00] <g0pai_ian> LazyLeopard: Mostly it seems that it's the telephone. Even after goodness knows how many years, they still can't get to grips with the fact that a club might choose to change it's name and regularly change their licence holder.
[00:00] <g0pai_ian> Certainly the software doesn't allow it.
[00:04] <WillTablet> Something in my room is bleeping at 03 past and 33 past the hour
[00:04] <LazyLeopard> Yeah, lots of systems like that out there...
[00:05] <g0pai_ian> Thanks for the chat folks, I have a few things to be doing for the morning. Good luck to those lofting balloons and all the trackers. Remember not to write systems like that LazyLeopard . . . it's a forgotten project of yours WillTablet. Gnite and I'll be reding the logs.
[00:05] <g0pai_ian> s/reding/reading/
[00:06] <craag> Good night Ian
[00:07] <g0pai_ian> What's the expression " I 'sed' that? . . . Good night Phil
[00:07] <fsphil> I totally grep what you mean
[00:08] <g0pai_ian> well don't AWK it around
[00:08] <WillTablet> craag: ATV looks really cool
[00:08] <WillTablet> But really really complex
[00:08] <SpeedEvil> g0pai_ian: On the other hand - a hell of a lot of 'normal' jobs are going to go away as automation kicks in in thenext 2-3 decades, and I can't see that being pretty
[00:09] <WillTablet> One question, where do you get the 6mhz bandwidth and how the hell do you avoid interference on such a high range?
[00:09] Action: LazyLeopard will keep an eye out for perls of wisdom...
[00:09] <fsphil> ghz
[00:09] <g0pai_ian> All my successes were systems that actually took other jobs away and replaced them with just a few. Then I became the victim . . .
[00:09] <fsphil> lots of bandwidth in the ghz bands
[00:10] <SpeedEvil> g0pai_ian: When driving, warehouse, retail jobs die - ...
[00:10] <WillTablet> Ah, I see
[00:10] <amell> Willtablet: Something in my study beeps every night at 21.46. Its been doing it for months. nobody can work out where its coming from. Suspected extraterrestrial interference.
[00:10] <WillTablet> I think it might have been my phone
[00:10] <SpeedEvil> amell: Set an alarm for 21:45

[00:11] <amell> Speedevil: we have been doing that. its so faint its difficult to locate.
[00:11] <amell> there was a suspicion it was coming through the ceiling, we went up into the loft at 21.45 and it wasnt up there.
[00:12] <WillTablet> fsphil: did you publish your code for that TV ntx2 experiment?
[00:12] <fsphil> not yet WillTablet
[00:12] <SpeedEvil> amell: B) it's someone being funny, and moving it daily
[00:12] Action: WillTablet is acting as if he'd understand it
[00:12] <amell> it is really strange.
[00:13] <SpeedEvil> That would be an amusing item.
[00:13] <fsphil> WillTablet: the transmitter bit is very simple
[00:13] <SpeedEvil> Sets of three items. You sync them, and then every day afterwards, one of them at random beeps.
[00:13] <SpeedEvil> never the same one twice

[00:21] pnephos (~casa@191.Red-79-153-11.dynamicIP.rima-tde.net) left irc: Ping timeout: 240 seconds
[00:27] <amell> wondering if dl-fldigi works without an internet connection
[00:29] <fsphil> it'll still decode
[00:29] <fsphil> it doesn't cache the data so it won't get uploaded after you regain internet
[00:29] <amell> can it catch up with telemetry uploads
[00:29] <amell> ah. bugger
[00:29] <amell> shame
[00:30] <SpeedEvil> It won't automatically setup the payload either of course
[00:30] <fsphil> there was talk of that
[00:30] <amell> i dont have a dongle or tethering for my laptop
[00:31] <fsphil> if you're handy with programming you could probably build a little caching app
[00:33] <Maxell> isn't catching-up useless on the current databse-setup?
[00:34] Lunar_Lander (~kevin@p54889424.dip0.t-ipconnect.de) left irc: Quit: Verlassend
[00:34] <fsphil> it would fill in some of the early gaps, but mostly yea
[00:40] <Maxell> hmm
[00:40] <Maxell> might be worth it
[00:40] <Maxell> might also be worth to brute-force an telemtry string
[00:41] <Maxell> like, flip each char once, and recalculate checksum
[00:41] <Maxell> or allow manual FEC
[00:42] <aadamson> wow, what happened to all the flights for tomorrow... spacenear isn't showing hardly anything at the moment ...
[00:43] <craag> aadamson: Those were jsut testing, at home, so the map has been cleared to prep for tomorrow.
[00:43] <craag> Otherwise you'd see a line drawn from people's homes to the launch sites.. :)
[00:43] <aadamson> oh, I thought once they were approved, they showed up *pending flight* :)
[00:44] <craag> No, they only show up when telemetry is uploaded.
[00:44] <Maxell> aadamson: flights also up even if they are not flying :P
[00:44] <aadamson> in the info on the right side of the screen
[00:44] <craag> That is linked to the balloons shown on the map
[00:45] Hoogvlieger (~Hoogvlieg@ip41-37-211-87.adsl2.static.versatel.nl) left irc: Quit: Leaving
[00:45] <aadamson> ah, so they will re-appear once they are in prep tomorrow... that makes sense
[00:45] <craag> Yep, as soon as they're switched on at the launch sites
[00:46] <craag> It'll make a lot more sense then :)
[00:47] <amell> if i had a 3G router, Id upload telemetry from elsworth
[00:47] <craag> They're very useful for HAB stuff
[00:48] <aadamson> cradlepoints are your friend... I have 2 of them and fobs on most of the carriers :)
[00:49] <craag> My 'room' router will drop back to 3G on the usb port if it doesn't have the WAN connected.
[00:49] <craag> So i just unplug it, carry it out to the car, stick the modem in it and plug it in.
[00:49] <craag> Then I've got a 3G magmount which improves things in spotty areas
[00:50] <amell> i have a 3G dongle but it doesnt work on 10.9, driver issues.
[00:50] <amell> I need to get a new one.
[00:50] <amell> aadamson: you taking the mick? have you seen the price on cradlepoints...
[00:51] <craag> I've got an E353 that works well on '3'
[00:52] <craag> Wow that is expensive
[00:52] <amell> mine is a tmobile 530 stick
[00:52] <craag> I've got a tplink mr3420, cost me 25 quid.
[00:54] <amell> What would be ideal if I could find a wifi router that can do NAT and connect to wifi and 3G.
[00:54] <craag> connect to wifi?
[00:54] <craag> As a repeater you mean?
[00:55] <amell> yes, to allow me to connect multiple devices to hotspots that only allow one device.
[00:55] <craag> Ah I see!
[00:55] <craag> Well anything with openwrt would do that I think :)
[00:55] <amell> good point
[00:56] <craag> Oh and the tplink runs an irc server too ;)
[00:56] <craag> We used it for inter-tent (cross-field) comms on VHF field day
[01:01] <aadamson> I have one of the MIFI's and they are *junk*, having a full class C routable address scheme with firewall, full speed access, flexiblity for wired or wireless and a full power AP, it worth the cost, because its really no different than a Linksys or Cisco personal router
[01:01] <aadamson> but it's a heck of a lot smaller, I think mine are 450's
[01:02] <aadamson> which appear to ahve been replaced, wonder what with?
[01:25] <qyx_> amell: rb750 or rb951, it has usb and costs around 25e
[01:25] <qyx_> if you want it to work out-of-box
[01:26] <qyx_> and don't want to dig into openwrt
[01:27] <qyx_> also works with most orange and t-mobile 3G sticks sold here in slovakia
[01:28] <amell> routerboard looks good.
[01:28] <qyx_> or you can buy rb411u/uahr (55e), nic alu box or waterproof abs box and some sierra wireless 3G minipci modem for another ~15e from ebay
[01:29] <qyx_> if you want to be more pro
[01:29] <amell> its a router, it doesnt need to be pro
[01:29] <amell> :)
[01:30] <Laurenceb> amell: routerboard stx5 looks epic
[01:30] <qyx_> once i had such router with 3G and internal lipo pack for outdoor apps
[01:30] <Laurenceb> im not convinced that its suitable for outside permanent use without a lot more waterproofing
[01:30] <qyx_> it is
[01:30] <Laurenceb> i notice conspicuous absence of IP ratings in the datasheet
[01:31] <qyx_> heh
[01:31] <Laurenceb> horizontal rain could get in through the cable covers, straight onto the main PCB
[01:31] <qyx_> they look that they will die in the first rain
[01:31] <amell> why would i be using it in the rain?!?
[01:31] <Laurenceb> no way it'd survive on a mast the way they indicate
[01:32] <Laurenceb> amell: the brochure shows it bolted to a phone tower
[01:32] <qyx_> amell: most of the routerboards (except soho boxes) are meant to be outside
[01:32] <Laurenceb> meant to be...
[01:32] <amell> maybe its potted&
[01:32] <qyx_> it isn't
[01:32] <Laurenceb> dunno if anyone has ever done in in the real world
[01:32] <qyx_> yep
[01:32] <Laurenceb> just PCB in basic case
[01:32] <qyx_> also with ubnt boxes
[01:32] <qyx_> they are the same
[01:32] <qyx_> water can get inside from the bottom
[01:33] <Laurenceb> but it could probably be modified to be waterproof
[01:33] <Laurenceb> water _will_ get into things if its possibly can
[01:33] <Laurenceb> its a rule of nature :P
[01:33] <qyx_> i know people (local isp's) who use it without further isolation
[01:33] <qyx_> but i tend to use bare pcbs in SCAME IP56 boxes
[01:33] <Laurenceb> interesting
[01:33] <Laurenceb> yeah
[01:34] <Laurenceb> i was thinking of getting some stx5 units for a semi permanent phased array hab receiver
[01:34] <SpeedEvil> As a general point - sealing properly permenantly powered equipment can be a failure
[01:34] <Laurenceb> yeah
[01:34] <SpeedEvil> Over having them vented and somewhat warmer than the environment
[01:34] <SpeedEvil> But yes - actual rain being able to get in isn't generally a good plan
[01:35] <Laurenceb> 6Mbps should be enough to shift raw SDR baseband
[01:35] <SpeedEvil> Plenty
[01:35] <Laurenceb> and range is like 100Km plus at the low rate
[01:35] <Laurenceb> crazy
[01:35] <qyx_> uh
[01:35] <qyx_> maybe you want to comply with etsi :X
[01:35] <SpeedEvil> 'semi permenant' -where are you thinking of placing this ?
[01:35] <SpeedEvil> Do you have a nearby site?
[01:36] <SpeedEvil> 'nearby'
[01:36] <Laurenceb> its somewhere with a big desert....
[01:36] <qyx_> phased array?
[01:36] <SpeedEvil> Oh - not very semi-permenant
[01:36] <SpeedEvil> right - nvm
[01:36] <Laurenceb> well, it could be done in UK as well for HAB
[01:37] <Laurenceb> it would be fun to try
[01:37] <Laurenceb> but getting line of sight would be tricky
[01:37] <qyx_> i was thinking o 3G enabled sdr
[01:37] <Laurenceb> 5Ghz 100Km is only with a good line of sight
[01:37] <Laurenceb> qyx_: yeah in UK/not a desert you could do it that way
[01:37] <Laurenceb> much easier
[01:38] <Laurenceb> clock sync via the 5Ghz would be interesting, but probably too much jitter for phased array tricks
[01:38] <Laurenceb> its really needs independent GPS sync
[01:39] <Laurenceb> but yeah this stuff isnt very useful for HAB is somewhere like UK with good 3G
[01:40] <Laurenceb> http://www.balticnetworks.com/media/catalog/product/cache/1/image/512x512/855cb094a20e32212f6a2c6ce54078fa/s/t/stx_5.png
[01:40] <Laurenceb> i think it can run a 3G dongle in there
[01:40] <Laurenceb> but theres no way that would survive in really bad weather
[01:41] <Laurenceb> it can run off POE too :D
[01:42] <Laurenceb> https://www.msdist.co.uk/product_MikroTik-RouterBOARD-SXT-Lite5.php
[01:44] <Laurenceb> supported by openwrt too, can't ask for more :-D

[09:03] <G6SUQ_Graham> none of todays flights are coming near me in London, so I wont be chasing today
[09:04] <ibanezmatt13> You should get something when we're high up no?
[09:05] <G6SUQ_Graham> for an elsworth launch it should take abt 20 mins for the blue-line to reach me

[10:36] <chrisstubbs> having a hard time soldering to this battery :(
[10:37] <eroomde> clean the surface thoroughly with IPA
[10:37] <eroomde> then rough it slightly with wet/dry paper
[10:37] <eroomde> FLUX
[10:37] <eroomde> and powerful iron with good thermal response and a big fat tip, say 80W

[10:37] <eroomde> move fast
[10:37] <chrisstubbs> I keyed it with a file, will try some IPA
[10:37] <eroomde> a powerful iron is probably the important bit
[10:38] <eroomde> as the metalwork on the battery can just wick away the heat otherwise and you'll have no joy - you'll just slowly boild the electrolites within
[10:38] <eroomde> boil*
[10:38] <G6SUQ_Graham> IPA? ... you mean beer?

[10:39] <eroomde> i find actually (not so much for batteries) that printer paper is great for cleaning up contacts before soliding
[10:40] <eroomde> it's slightly abrasive, and slighty acidic

[10:40] <G6SUQ_Graham> any rough-ish paper sould be okay
[10:40] <eroomde> so it's great for cutting rid of oxide and grime layers before soldering
[10:40] <eroomde> sure, i say printer specifically cos it's usually got a bit of acid in

[13:08] <mfa298> serial can be useful but only so that dl-fldigi can correct frequency if the transmitter drifts to far.
[13:08] <M1DLG> I'd still like to use FLdigi for data in general, and yes I'd like to push auto configure and let the rig tune

[13:10] <M1DLG> neil, I wouldn't worry about it. I was just wondering, your so close :)
[13:10] <mfa298> most data modes work by sending the audio from the radio to the decoder program - even if the radio has some decoding built in you may find the computer software does a better job as it will be updated more often.
[13:10] <aadamson> took me a bit to figure out the chart, but I think I've got it now... for a given payload weight, there will be a mas free lift to avoid burst and a float altitude
[13:11] <aadamson> mas = max
[13:11] <M1DLG> perhaps we may bump into each other at a rally or something
[13:11] <WillTablet> Neil_M0CJM: coverage patchy here
[13:11] <M1DLG> I kind of like teh idea of tracking a balloon or 2 at the Newbury rally, perhaps having a launch from there.
[13:12] <WillTablet> ibanezmatt13: bron?
[13:12] <fsphil> $$LNOxyx%.7?,q -- still weak :)
[13:12] <ibanezmatt13> yeah Willdude123
[13:12] <amell> bron was not as strong as norb2, thought it would be ok though :(
[13:12] <WillTablet> Lemme see where that is
[13:13] <ibanezmatt13> it's an rfm so it probably drifted but I can't see it
[13:13] <Neil_M0CJM> Iwill try for sure later but would hope so
[13:14] <fsphil> or reset
[13:14] <LeoBodnar> chrisstubbs: it would in the night but during the day it stretches up a bit so if it does not burst it can go higher - towards 6000. It's a bit difficult to calculate because of the nonelastic and nonlinear stretching process
[13:14] Action: chrisstubbs crosses fingers
[13:15] <mfa298> M1DLG: there was some talk of trying to do a launch from the Bournemouth rally although various things got in the way of that.
[13:15] <chrisstubbs> looks like its levelling off, vertical rate is dropping off
[13:15] <aadamson> hehe *was* dropping off ;)
[13:15] Joel_re (~jr@103.224.4.151) left irc: Ping timeout: 264 seconds
[13:15] <LeoBodnar> yeah, it is fully inflated now and the stretching process started
[13:16] <LeoBodnar> with your details full inflation should be at about 4500m
[13:16] Action: mfa298 wonders if some of the ideas we had for Bournemouth could be done at Newbury
[13:16] Action: mfa298 looks at craag
[13:16] <chrisstubbs> thanks LeoBodnar
[13:18] <craag> mfa298: ?
[13:18] <M1DLG> Not enough time for anything to happen this year, but next year perhaps.
[13:18] <craag> mfa298: When's newbury?
[13:19] <mfa298> there was a comment about doing a launch at the newbury rally. So I wondered if the "bus trip" idea could work for that.
[13:20] <ibanezmatt13> The NTX2B is superb. From 21 deg C to -2 deg C, no change at all

[13:24] <eroomde> i was amused at the prtests of some rsgb thing when the conf is planned
[13:24] <eroomde> protests*
[13:25] <Laurenceb> yo eroomde: I was going to ask you something
[13:25] <eroomde> there always seems to be some raynet something or pile-up something else taht someone (except hab flyers, usually) will get het-up about
[13:25] <Laurenceb> so I've got this groovy kalman filter based linear actuator thing
[13:25] <eroomde> yuhu
[13:26] <Laurenceb> but it sometimes goes mad
[13:26] <gonzo_> there is a knitting meet that day too!
[13:26] <eroomde> unstable mad?
[13:26] <Laurenceb> due to tiny movements being absorbed within the actuator, so when its trying to estimate the movement to change an applied pressure it get it badl wrong
[13:26] <LeoBodnar> is knitting a new habbing?
[13:27] <Laurenceb> if its been stable and not changing pressure or moving much for a while
[13:27] <eroomde> is it modelling the applied pressure?
[13:27] <G6SUQ_Graham> I believe that Dave Ake's next flight will be with a knitted balloon
[13:27] <Laurenceb> is there some sort of "filter" type technique i can use to inhibit the kalman filter during these processed?
[13:28] <MatB> wow, just realised how little bandwidth i'm getting in over the sound card and need to tune the rx better. duh. getting nlrb through loud and clear now on 434.5530
[13:28] <Laurenceb> yes, it models the elastic properties of the material its in contact with
[13:28] <eroomde> hmm, well the usually go unstable when 1)
[13:28] <Laurenceb> most of the time it works very nicely - it has a model of viscoelasticity, thixotropy and nonlinearity
[13:29] <eroomde> something you're not modelling but usually gets absorbed by process noise gets actually too big
[13:29] <eroomde> 2) linear assumptions break down
[13:29] <eroomde> i don't know of any heuristicy 'ignore this' things
[13:30] <malgar> what does "flightmode" mean in NORB2 telemetry?
[13:30] <Laurenceb> ive tried some really n00b beadband type stuff
[13:30] <Laurenceb> but only for the motion control - it seems a help a little
[13:31] <Laurenceb> maybe i should try to get my head around some kind of deadband pre processor for the kalman inputs

[14:56] <chrisstubbs> looks like he just got a position
[14:56] <StudentDeNayer> Hi i got a question about the cpu i should use : i had a avr atmega 328p but i need to replace this one with a pic but got not clue wich one to take and to find code for this with rfm22b and a neo 7 (gps )
[14:57] <daveake> Why do you *need* to use a pic?
[14:57] <daveake> Most people use whatever they're familiar with
[14:58] <StudentDeNayer> cause the avr can't be delivered in time
[14:58] <StudentDeNayer> and my promoter is "forcing" me to use it
[14:58] <chrisstubbs> forcing anyone to use PIC must be against human rights
[14:59] <LeoBodnar> what do you mean "find the code"?
[14:59] <SP3OSJ> ok
[14:59] <LeoBodnar> can't you write it yourself?
[14:59] <daveake> I bet you can get an AVR in less time than it takes to port your code from avr to pic
[14:59] <daveake> or indeed write from scratch
[15:00] <LeoBodnar> you can simulate AVR on FPGA
[15:00] <Upu> ibanezmatt13_ is walking down the track
[15:00] <daveake> UsefulAnswersRUs ?

[15:00] <Upu> I'm afk a few
[15:01] <chrisstubbs> StudentDeNayer, what country are you from? someone may know a supplier
[15:01] <StudentDeNayer> Belgium
[15:01] <mfa298> there's enough places that sell the various ATMegas you should be able to get something pretty quickly unless you're living in Timbuctoo.
[15:01] <StudentDeNayer> Ye i think he's using it as the excuse to let me use pic i have to order trough him
[15:01] <daveake> Do you need a chip for a pcb you're designing, or do you want something on a board?
[15:02] <mfa298> If you can't get an ATMega328p it may be better to look for an alternative ATMega rather than changing to PIC (assuming you've got some code already working for the ATMega)
[15:02] <daveake> 'cos I bet you can order an Arduino for delivery Monday or Tuesday
[15:02] <StudentDeNayer> Both but i've made the pcb aleady so i can use the chip
[15:02] <chrisstubbs> what package? DIP or TQFP?

[15:03] <daveake> So you think you can get a pic and get the pcb laid out and manufactured in less time than it takes to get an AVR?
[15:03] <daveake> 'cos I *highly* doubt that
[15:03] <StudentDeNayer> Thats what i think aswell, and i have no xp with pic
[15:04] <LeoBodnar> it's a good opportunity to get some xp
[15:05] <LeoBodnar> so i suggest use PIC, redo the board and write your own software
[15:05] <daveake> I have nothing against pics (well aside from instruction set and the bank switching and....) but if you already have a board it seems mad to not use it
[15:07] <g8khw_tab|> Your looking at the wrong pic then dave
[15:08] <daveake> Sorry couldn't resist :-)
[15:08] <daveake> I've used some much better pics

[18:41] <Upu> *cough* http://imgur.com/a/edbM1
[18:42] <disruptivetech> Cool, somehow the great google never got that one in my search results
[18:42] <aadamson> ah boo hiss, there is spi on the rPi, where is the si4xxx chip :)...
[18:43] <mfa298> disruptivetech: they've been used but for simple telemetry they're somewhat overpowered and there's several things that can go wrong easily (SD card falling out, system overheating etc.)
[18:43] <sp2ipt> Upu: ROTFL 5 mins in -20 deg of work ;)
[18:43] <Upu> what the Pi ?
[18:44] <Upu> they are way hardier than you think
[18:44] <sp2ipt> don't tell me they're better than uP with custom code :)
[18:44] <Upu> well the camera is way better
[18:44] <sp2ipt> ok, the camera prolly is :)
[18:44] <disruptivetech> The SD thing is the least of my concerns, we have the ability to do shake and thermal tests
[18:45] <sp2ipt> my bad
[18:45] <Upu> with the exception of the SD card which is an easy fix they are pretty robust
[18:45] <eroomde> i just bought a computer vision camera
[18:45] <eroomde> god, you pay a lot
[18:45] <eroomde> just for lossless picture transmission and a bit of control over the exposure and frame rate
[18:46] <disruptivetech> At some point I might switch to a cubie, which has integrated NAND on board
[18:47] <eroomde> they're also mostly firewire which makes embedded a bit harder
[18:47] <mfa298> Wait until you're working with lots of Pi's then say they're robust. I don't think I've had a clean boot of the >80 pi's I'm using yet.

[18:48] <eroomde> without the oblig pc104 jokes, the hardiest embedded thing I've ever used was a core 2 duo board from ADL
[18:48] <eroomde> adl-usa.com
[18:48] <eroomde> their support was also excellent
[18:48] <eroomde> we dumped this thing into a glacial waterfall, crashed it into avelanche fields, and rebooted it many thousands of times in a high-emi environment, with me fiddling with it without static precautions
[18:49] <eroomde> the only time it crashed was because of my crap kernel-space additions
[18:49] <disruptivetech> I have 2 Pi and 2 Cubie's and haven't had any stability issues. Most of the boot or pure stability issues I've seen to this point with the other guys I know that have them are power supply related.

[18:51] <disruptivetech> Yeah, all of my peripherals are always off of a powered hub, with the exception of the WiFi or BT4 adapter in the second USB slot on the board
[18:51] <aadamson> I use them all the time for an internet linking project (digital radio) and of all of them the BBB is by far my favorite and it's much more powerful than the Pi too... it is minus a few glam features and costs more, but for a headless box, it's pretty hard to beat
[18:52] <eroomde> i like the bbb too, though i am nto a huge user of either
[18:52] <disruptivetech> e-link or dstar?
[18:52] <eroomde> but the bbb is much better designed
[18:52] <eroomde> and the cpu is better
[18:52] <disruptivetech> One would hope its a much later design
[18:52] <aadamson> disruptivetech, neither (you will *NEVER* catch me on d-star!)... NXDN, I have 3 repeaters in atlanta all linked via allstar on analog, and NXDN on digital
[18:53] <eroomde> the great promise of pi's - the ecosystem that will let everyone go from logo to kernel-hackers, has yet to materialise much, it seems
[18:53] <aadamson> whoa, if only it were that easy - logo -> kernel hacking :)
[18:53] <mfa298> the Pi makes a good payload if you want to link the PiCam to it but if it's just a basic telemetry / sensors system then a dedicated microcontroller (AVR/Pic) is likely to be much more stable
[18:53] <eroomde> aadamson: there is obviously a small amount of stuff in the gap :)
[18:54] <tweetBot> @NORB_HAB: Another nice pic from the burst, spectacular footage! More to come on Flickr later #ukhas :D http://t.co/yNltmCtgLp
[18:54] <eroomde> there must be a gap for a super-awesome into to computer science and programming for teens
[18:54] <eroomde> which seems like the prime time
[18:54] <eroomde> like SICP but assuming less knowledge of calculus and so on for all the motivating examples
[18:55] <disruptivetech> uuummm, the perspective of that shot seems to be looking down at the parachute as if separated from its line
[18:56] <disruptivetech> But very cool
[18:57] <eroomde> disruptivetech: immediately after burst it's wildley chaotic
[18:57] <aadamson> Upu, capacitance on the 34450a?
[18:57] <aadamson> seems they left if off the 34461a :(
[18:57] <eroomde> oooh what did a miss?
[18:57] <eroomde> debugging measurement problems is my favourite
[18:57] <Upu> capacitance
[18:57] <Upu> but I have an LCR meter anyway
[18:57] <aadamson> eroomde, probably nothing, I'm in the market for a DMM and Upu planted a seed
[18:57] <disruptivetech> Yeah, the video footage from our first two flights was all over the place too
[18:57] <eroomde> oh
[18:58] <aadamson> I want something that I can easily do dataacquisition with as well
[18:58] <eroomde> well i had this chat with upu t'other day
[18:58] <Upu> eroomde remotely spent my money
[18:58] <eroomde> i think any of them will do that, it's probably just a question of precision/resolution
[18:58] <aadamson> hacking and stm32f3 to do it isn't my idea of good use of my time :).. .might have been fun, but not good use
[18:58] <eroomde> the 34461 is great if you want in-unit logging and histograms
[18:58] <aadamson> yeah, but no capacitance measurement :(
[18:59] <eroomde> if you can use a usb cable and python then it's neither here nor that between that and the 34401
[18:59] <eroomde> which is what i have
[18:59] <eroomde> yeah, high end stuff never does capacitance
[18:59] <eroomde> it needs a separate instrument really
[18:59] <aadamson> yeah, compromise, but could be useful once in a while... 34401's seem to be cheap on ebay too
[19:00] <eroomde> well i guess a lot of testing environments might be upgrading to the 34461
[19:00] <eroomde> the thign is, i wouldn't get a 6.5 digit thing that i wasn;t going to buy/get calibrated
[19:00] <eroomde> as at that accuracy it's a bit pointless unless you're going to spend the money keeping it calibrated
[19:00] <aadamson> yeah, understood on that topic.
[19:00] <eroomde> so i'd be suspicious of a 2nd hand one
[19:01] <eroomde> or rather, a 2nd hand one that might not be cheaper once cal is added than a new one
[19:01] <eroomde> i keep it calibrated as we sell things where we need a cal certificated with a traceable instrument used to calibrat it, so it's a no-brainer
[19:01] <eroomde> for home use, i'm not sure if the $300/yr (or whatever it is) i could justify

[19:03] <eroomde> well, there are several fans here of the 6632b psu
[19:03] <eroomde> as there seems to be a seam of them on ebay for super-cheap
[19:03] <eroomde> they're going for about $150 on ebay-uk
[19:03] <eroomde> which is <10% retial price
[19:04] <eroomde> you'll want a decent dmm to keep *those* calibrated though, as they're good to mV settings :)
[19:04] <eroomde> might be worth getting a 2nd hand 34401 and some kind of standard
[19:05] <eroomde> vishay 0.005% resistors are about $50/each
[19:05] <eroomde> and there's a guy on eevblog who often gets recommended for cheap voltage standards
[19:05] <aadamson> good feedback, looks like about $250 (one) to $500 in the US... at a fast past glance on ebay
[19:05] <eroomde> you can hear the fan-noise though
[19:05] <eroomde> on the 6632b
[19:06] <eroomde> so i wouldn't give up my nice old 10-turn pot psu for everyday use, as it's silent
[19:06] <aadamson> ah, only gpib remote controllabe?
[19:06] <eroomde> no, serial works fine
[19:07] <eroomde> scpi or whatever it's called
[19:07] <aadamson> hehe serial... such 80's technology wasn't even thinking of that :)
[19:07] <eroomde> even in 50 years, i hope thigns will still come with a serial debug
[19:07] <aadamson> watch out looks like LeoBodnar gonna go flying again :)
[19:07] <mattbrejza> still decades older than gpib...
[19:08] <eroomde> i do like the look of the 34461
[19:08] <eroomde> but
[19:08] <eroomde> 30s boot time!
[19:08] <eroomde> for a multimeter!?
[19:08] <eroomde> what the hell
[19:08] <Laurenceb> lolz
[19:08] <mattbrejza> hope it doesnt run windows...
[19:08] <eroomde> i'd need to have my fluke to hand at all times for quick measurements, lest i go out of my mind
[19:08] <eroomde> it does
[19:09] <eroomde> windows ce
[19:09] <Laurenceb> heh
[19:09] <mattbrejza> well that explains it
[19:09] <aadamson> eroomde, yea I saw that! talk about 80 tech :)
[19:09] <eroomde> that's whay i like the 34401
[19:09] <eroomde> turn it on, and it's on
[19:10] <aadamson> and there's always those *tubes* :)...
[19:10] <eroomde> i have never gone back as far as valve test equipment
[19:10] <eroomde> but i do like the early stuff
[19:10] <eroomde> i like being able to fix it
[19:11] <eroomde> wouldn't mind one of the old tek 'portrait' valve scopes though
[19:11] <aadamson> sri, I meant the VFD in the 34401 :)
[19:11] <eroomde> like the 545 (i think?)
[19:11] <eroomde> oh that!
[19:11] <eroomde> yes they don't last forveer
[19:11] <eroomde> which is why i like that it turns on quickly
[19:11] <eroomde> so i don't get into the habit of just keeping it on all day
[19:12] <aadamson> hehe... LeoBodnar got a prediction for B-42?
[19:12] <aadamson> coming my way maybe?

[19:36] <ibanezmatt13> slow*
[19:36] <ibanezmatt13> bit tricky mattbrejza :P
[19:36] <mattbrejza> well depends on the laptop
[19:36] <mattbrejza> generally theyre very easy to get out
[19:36] <enkidu> if you have slow ftp... I had transfers around 120MB/s
[19:37] <Geoff-G8DHE-M> network connection?
[19:37] <ibanezmatt13> hmm
[19:37] <mattbrejza> transfer via fldigi
[19:37] <ibanezmatt13> haha, no thank you, had enough of that for a day! :D
[19:39] <aadamson> ibanezmatt13, did you figure out how come the flightmode didn't change or did it and telem didn't update?
[19:40] <aadamson> and what is the advantage/not of this discussed flightmode change (gps config change?)
[19:40] <ibanezmatt13> not sure what you mean aadamson, flight mode seemed to work perfectly. You mean like bearing's and stuff?
[19:41] <ibanezmatt13> basically, with Ublox at 12KM and above they don't work unless you enable this flight mode
[19:41] <ibanezmatt13> So I was just hoping to god my code would work when it got to that point :)
[19:41] <aadamson> no and maybe I missed it. you had said that FM was suppose to change at 12K... so the FM=1 was a change from FM=0 at launch?
[19:41] <aadamson> I somehow thought that FM=1 at launch too, but maybe I was wrong
[19:42] <aadamson> I was in and out this am watching the activities
[19:42] <ibanezmatt13> Erm, I'm not really sure :) Someone might know
[19:42] <ibanezmatt13> I just know the flight mode was a crucial stage at 12KM, that was all I'm sure
[19:43] <aadamson> ok, sorry, not trying to confuse anyone... in telem, at least all that I saw FM was always equal to 1
[19:43] <Geoff-G8DHE-M> On NORB you have a parameter called Flightmode ?
[19:43] <aadamson> as it shows now
[19:43] <aadamson> you kept talking, this morning about it changing, but I don't think it ever did in telemetry
[19:44] <aadamson> I guess I should go look at the history and see...
[19:44] <ibanezmatt13> yes Geoff-G8DHE-M, I was sending the result of checking flight mode was enabled so I could be sure it wouldn't fail
[19:45] <Geoff-G8DHE-M> Ah right

[19:45] <ibanezmatt13> eroomde: ping
[19:46] <aadamson> yes, ibanezmatt13, the entire flight shows FM=1 so how were you able to tell that it actually switched vs. was on the entire time?
[19:46] <ibanezmatt13> FM=1, where is this?
[19:46] <ibanezmatt13> definitely norb?
[19:47] <aadamson> norb2 right?
[19:47] <aadamson> flightmode=1
[19:47] <ibanezmatt13> yes
[19:47] <ibanezmatt13> ah flight mode
[19:47] <aadamson> go look on spacenear
[19:47] <aadamson> and it was 1 the entire flight
[19:47] <ibanezmatt13> I thought you meant FM as in frequency modulation
[19:47] <aadamson> sorry, shorthand
[19:47] <ibanezmatt13> yeah of course, flight mode = 1 means flight mode is set
[19:47] <aadamson> fm = flight mode
[19:47] <ibanezmatt13> flightmode = 0 is bad
[19:47] <ibanezmatt13> thankfully never happened
[19:47] <aadamson> ok, I guess I'm just confused
[19:48] <aadamson> I saw a post from you when the vehicle was at 11K and you say something to the effect of FM better change at 12K.
[19:48] <aadamson> that made me think that it wasn't prior and yet the telemetry showed 1 the entire flight
[19:48] <aadamson> so was curious why the hope it would change?

[19:50] <ibanezmatt13> haha oops
[19:50] <ibanezmatt13> sorry, in the midst of the confusion I really meant, I hope flightmode works, kinda thing
[19:51] <aadamson> ok, at the time, I purposely watched it go through 12K just to make sure something changed and it never did, hence the query.
[19:51] <aadamson> but no worries, I just wasn't sure
[19:53] <ibanezmatt13> hmm interesting: http://pbrd.co/1h6FHFQ :)
[19:53] <ibanezmatt13> that's quite the curve

[19:56] <malgar> could you suggest me a temperature sensor that could work even at -60 -70 °C? to put outside the payload

[19:57] <SpeedEvil> Combined with an internal ds18b20, an opamp, and an ADC, and you're done.
[19:57] <SpeedEvil> Type K gives about 41uV/C - which is quite a lot
[19:57] <enkidu> diode or PN junction of transistor, but you have to scale it

[20:00] <eroomde> your voltage measurement looks a bit noisy
[20:01] <ibanezmatt13> hey the pictures are absolutely stunning. Yeah it does, I noticed that in testing though. I don't think my analog reading function was very good
[20:01] <eroomde> lots of things you can do about that
[20:01] <eroomde> rc filter, longer adc integration time, turn off nearby clocks, etc
[20:02] <ibanezmatt13> yeah, I'm pleased with the general decreasing voltage, shows it was working to some extent

[20:04] <malgar> and the rifle?
[20:05] <ibanezmatt13> At that point, we just legged it back to the car and took off before he had chance to shoot us, so just missed the rifle :)

[21:31] <mattbrejza> although those might be on the HF side

[22:24] <aadamson> didn't get it yet... borrowed one from kd2eat in NY and I can put that on later... easy enough to pull the solder off from the paste mask and solder down the gps

[22:25] <Upu_M0UPU> yeah they are pretty easy to solder
[22:26] <aadamson> has the jtab 10 pin on the back so hopefully, I'll at least make LED's blink before the night is over... I think one of my LED's is in backwards even tho I checked it a million times, I think it's marked wrong...
[22:26] <Upu_M0UPU> what is the IC next to Y2 ?
[22:26] <aadamson> but I've got tweezers so flipping that around is easy
[22:27] <aadamson> That's the TI cdcel913 - a digital PLL controllable over i2c, works like a VCXO but the frequency is completely programmable
[22:27] <aadamson> an experiment... actually :)
[22:29] <aadamson> and I used some *wicked small* crystals this time... Wow were they tiny... Y8's as they are called... 27mhz for the DPLL and 16 for the processor (couldn't get an 8, but no matter you can use anything for it pretty much
[22:29] <Upu_M0UPU> nice be interested to see how that goes

[22:31] <aadamson> I missed a couple of stupid things.. a pull up here or there, but it will work as is, with using the internal pull up in the processor... I just may have a couple of things that *float* on reset
[22:31] <Upu_M0UPU> not particularly now
[22:31] <Laurenceb> aadamson: you want tagconnect for that stm32
[22:31] <Upu_M0UPU> DL7AD lift is about 65g but try keep it <20g

[22:32] <Upu_M0UPU> no idea never measured it
[22:32] <aadamson> ah... I know what that is
[22:33] <aadamson> yeah, we'll see... I thought about it, but it mean a footprint with holes and I was trying to not deal with a very complex layout for the v0.1 version (which actually became the v.02 version)

[22:33] <Laurenceb> good choice
[22:34] <aadamson> yeah F0 and L0 were just too restrictive, so it's a 48pin 151CB, looked at the DFN, but really wasn't any board space advantage

[22:35] <Laurenceb> compared to AVR...
[22:35] <aadamson> I actually have most of the code up and running, on the Nucleo/152-discovery boards, so I just need to move some GPIO and it should come up (I hope)
[22:36] <aadamson> Well, I say that, this will be my first 2.0v board, I usually work at 3v3... actually I can power this at 3v3 too... hmm I'll probably do that to bring it up the first time
[22:37] <aadamson> the only part that isn't 3v3 compatible is the cdcel913, it's a 1.8 part (which I was going to run at 2.0v :))... but it's on a separate bus because at the last minute I decided I may want to run the board at 3v3 and use an ldo for 1.8 for the TI part ...

[22:38] <mikestir_2E0MXS> I think I had one green off it
[22:38] <mikestir_2E0MXS> and it's not exactly far from me

[23:40] <amell_> Gah 113 apparently doesn't measure current
[23:40] <malgar> https://www.mapbox.com/blog/processing-landsat-8/ here you can find a post-processing tecnique to remove haze and give brilland colors to the ground
[23:40] <Lunar_Lander> the fluke at work could not measure a 22 pF capacitor
[23:41] <mikestir_2E0MXS> right I'm off
[23:41] <Laurenceb> blood pressure cuff hardware would work fairly well
[23:41] <Laurenceb> maybe 2 hours or so
[23:41] <malgar> is is for satellite images but I think that it could work well on HAB images too
[23:41] <Lunar_Lander> but that is maybe because it is not a dedicated capacitor meter
[23:42] <fsphil> wonder if B-42's descent is final
[23:44] <fsphil> you could use a ruler to measure a 22pf cap. might not give you the answer you want though

[23:48] <amell_> RocketBoy: Did you recover HL1?
[23:49] <RocketBoy> nope - pretty sure it was taken
[23:49] <RocketBoy> I found the balloon remnants
[23:49] <amell_> Dang. Where did it land
[23:49] <RocketBoy> but no tracker or chute
[23:49] <RocketBoy> then later I heard the tracker -
[23:50] <RocketBoy> got some decodes and it was moving along a road
[23:50] <amell_> Grrrr
[23:50] <RocketBoy> this was a couple of hors after landing
[23:50] <RocketBoy> hours
[23:50] <amell_> Phone number on it?
[23:51] <RocketBoy> nope - got sidetracked and forgot to pu one on
[23:51] <RocketBoy> https://www.flickr.com/photos/16828840@N07/13495718155/ <<< balloon remnants\
[23:51] <Upu_M0UPU> shame Matt was 2 miles from it
[23:52] <Upu_M0UPU> but was so excited he missed my subtle hints
[23:52] <Upu_M0UPU> "go find Steve's tracker"
[23:52] <RocketBoy> well I was only about 10 - 15mins behind it
[23:52] <amell_> So passing car saw it, thought it looked interesting and took it
[23:53] <amell_> Is it dog walking area?
[23:53] <Upu_M0UPU> was it just a tracker or some other equipment ?
[23:53] <RocketBoy> just a tracker
[23:53] <MatB> That's a bugger. Is it not obvious it's a tracker and therefore a stupid thing to steal!?
[23:53] <RocketBoy> in a big lump of glued up ploystrene
[23:54] <amell_> Passer by would not know what it is.
[23:54] <RocketBoy> well there was the balloon and chue
[23:54] <MatB> Yeah but they must have thought it interesting enough to take it home
[23:54] <amell_> I saw it, it honestly didn't look that interesting.
[23:54] <RocketBoy> maybe they were driving along and it was in the road
[23:55] <amell_> Yeah and chucked the balloon on the hedge
[23:55] <RocketBoy> but they must have had to cut away the balloon
[23:55] <amell_> Plausible
[23:55] <RocketBoy> and left it

[23:56] <RocketBoy> The balloon remnants were almost exactly where the predicted track would have taken it
[23:56] <Upu_M0UPU> it was very stable
[23:57] <RocketBoy> also - when I decoded the car moving along later the sequence number had been reset
[23:57] <MatB> Just out of interest, what's the rough costs of building and launching one of these HABs?
[23:57] <amell_> How far away was the car track?
[23:57] <RocketBoy> so they must have turned it off and on again
[23:57] <Upu_M0UPU> web log time ? :)
[23:58] <RocketBoy> it was on the same roaad as the balloon - abut I had moved to about a mile away
[23:58] <RocketBoy> nothing on it to reg=ference a web site
[23:58] <RocketBoy> reference
[23:59] <amell_> Shame.
[23:59] <amell_> Anything on the pcb?
[23:59] <RocketBoy> bl**dy PC packed up just as I was about to give chase
[23:59] <RocketBoy> nope - not a pcb
