[08:24] <Rebounder> wtf
[08:25] <Rebounder> was to dl7.. mm
[08:25] <DutchMillbt> DL7AD running @aprs ;-)
[08:25] <DL1SGP> 35min Rebounder
[08:25] <DL1SGP> at least that would be 1100 local then hehe
[08:25] <DL1SGP> and 0900 UTC
[08:25] <DL1SGP> but add the hab-ish part :D
[08:26] <PE2G> Moin DL1SGP. What is the launch location?
[08:29] <DL1SGP> errrr
[08:29] <DL1SGP> heel goedenmorgen PE2G
[08:29] <DL1SGP> Launch pad is Obersgörsdorf, Germany
[08:30] <DL1SGP> a place that does not exist :D
[08:30] <PE2G> Thanks. That's somewhere south of Berlin?
[08:31] <DL1SGP> should be the case I assume DL7AD is beaconing his current location via APRS
[08:32] <PE2G> OK, will check that
[08:32] <DutchMillbt> Good morning DL1SGP . PE2G the aprs beacon is on the map
[08:32] <DL1SGP> but that location of the beacon is Wildau, the place of his University where he assembeled the stuff
[08:33] <DL1SGP> so he might move a bit for the launch
[08:33] <PE2G> Roger
[08:33] <DutchMillbt> oke
[08:33] <DL1SGP> as Wildau based launch has been changed to Oberswhateverplace
[08:37] <DL1SGP> launch location should be this place https://maps.google.dk/maps?q=G%C3%B6rsdorf+b.+Storkow,+Deutschland&hl=de&ie=UTF8&ll=52.261013,13.800888&spn=0.193745,0.507088&sll=52.250032,13.846292&sspn=0.048448,0.126772&oq=G%C3%B6rsdorf+b.+Storkow&t=h&gl=dk&hnear=G%C3%B6rsdorf+b.+Storkow,+Deutschland&z=12

[08:40] <DL1SGP> yea
[08:41] <DL1SGP> his APRS is not updating any more
[08:42] <PE2G> Difficult reception angle for me. I have a blind spot there, will try nevertheless.

[08:45] <en4rab> What power are people using for APRS from a balloon?
[08:47] <DL1SGP> en4rab: depends on the technology used but not much
[08:52] <LeoBodnar> from 10 to 100mW en4rab
[08:52] <LeoBodnar> 5W if you are in the U.S.A.
[08:53] <DL1SGP> morning LeoBodnar :D
[08:53] <LeoBodnar> morgen!
[08:53] <en4rab> thankyou, I have been trying to get my head round if you could use a supercapacitor and solar cells instaed of a battery for a tracker
[08:53] <LeoBodnar> of course you can
[08:54] <en4rab> I particularly liked your solar cells on the ground plane wires LeoBodnar

[08:56] <en4rab> looks fragile though, have you seen the flexible powerfilm cells
[08:56] <LeoBodnar> are you doing launch controller DL1SGP XD
[08:56] <LeoBodnar> the *ARE* fragile
[08:57] <LeoBodnar> these? http://leobodnar.com/balloons/B-5/Pages/9.html
[08:58] <en4rab> yes indeed
[08:58] <DL1SGP> LeoBodnar: other option would be continuing to construct blends for my mother's window :D
[08:58] <LeoBodnar> when you are doing countdown voice you are not allowed to sound excited

[08:59] <LeoBodnar> i see what you did there
[09:00] <DL1SGP> there is the mobile radio station of Sven's local HAM radio club on site at university, would have been sweet to know if they had HF or Echolink to establish a link hehe
[09:00] <LeoBodnar> are we haveing a hold at T plus 1?
[09:00] <DL1SGP> D-3 is now entering the ISH window

[09:25] <Maxell> DL1SGP: he's on 144.655MHz
[09:26] <DL1SGP> distance a bit too high when using omnidirectional only :)
[09:26] <DL1SGP> I gonna try echolink in a bit they have their mobile radio station there so possibly there is a rig running for echolinki
[09:26] <DL1SGP> it is quite something nice to get to show people how a contact is run :D
[09:28] <Maxell> yeah those rigs automaticly beacon your qrv frequency
[09:28] <Maxell> not that nice if you start freebanding or going on pmr with >500mW :)
[09:28] <DL1SGP> lol
[09:29] <DL1SGP> DL7AD is beaconing again
[09:30] <DL1SGP> they might be using that 2m qrg for their local intercomm

[10:58] <craag> ouch
[11:00] <mfa298> from what he was saying last night I think he's got jpeg quality at 50 and was wanting to fix the shutter speed
[11:00] <craag> jpeg quality isn't bad
[11:00] <craag> but the exposure is way off and the lego man is far too close

[11:01] <craag> I found it was actually better the let the camera decide about exposure
[11:01] <craag> and matrix metering ftw (cheers dave!)
[11:01] <daveake> fixing shutter speed needs ... care. Best way would be to check the shutter speed on some properly exposed photos using the same model camera on a previous flight
[11:02] <daveake> yeah matrix is the key
[11:02] <daveake> My first pi cam flight defaulted to spot, which didn't go well
[11:02] <mfa298> I'd suspect the pi camera isn't be best for that sort of shot, unless you fiddle with it I think the best minimum focus is around 1m and they're not all the same out the box
[11:02] <daveake> yeah they're not good close up

[13:43] <mfa298> I think I've had to power cycle the 14.04 desktop at work more times in the last couple of weeks than I've had to do for windows 8 in over a year.
[13:43] <mfa298> craag: there seem to be lots of graphics drivers bugs with nvidia cards.
[13:45] <craag> I'm using the 3.14 FOSS drivers with an AMD Tahiti-XT card and am very impressed. VLC worked out-of-the-box with video decoding acceleration, which takes a good bit of fiddling with fglrx.
[13:46] <mfa298> although since updating to win 8.1 on the laptop I've had some graphics driver issues with the intel card, but that just goes blank for a split second then everything's back to normal. the only reason I know about it is MS puts up a bubble saying the driver had crashed and restarted

[13:48] <craag> Graphics drivers are still a sore point with linux. AMD has got a lot better recently though, and I believe Wayland should make the API for the driver authors a lot easier.
[13:51] <mattbrejza> i would probably be using linux if it wasnt for the graphics drivers issue
[13:53] <mfa298> I had fewer issues on 13.10. I think half the issue I'm seeing is that it looks like Ubuntu set a release date well in advance and stick to that date whether the software is actually ready or not.
[13:54] <craag> The proprietary graphics drivers always trail the ubuntu releases
[13:54] <craag> To be fair - the nvidia proprietary drivers are not ubuntu's software.
[13:54] <mfa298> so 14.04 should probably only really be considered alpha/beta
[13:55] <mfa298> most of the crashing I had was with the noveau drivers. It's less crashy with the propietry ones.
[13:55] <craag> Oh ok, so it's kernel bugs.
[13:57] <mfa298> I think one of the issues was with the various webapp widgits (gmail etc.) and noveau in unity.
[13:57] <craag> heh unity
[13:57] <craag> Yeah can't speak for that tbh, don't use it.

[13:58] <mfa298> although all of OpenCL seems to be broken with nvidia drivers as well
[13:58] <craag> Xubuntu ftw!
[13:58] <craag> Yep that's well known, doesn't nvidia have their own rival tech?
[13:58] <craag> cuda
[13:59] <craag> OpenCL was AMD
[13:59] <mfa298> it worked fine in 13.10 just not 14.04
[13:59] <craag> Hmm
[13:59] <craag> You really are breaking down my defense of ubuntu here :P
[14:00] <mfa298> CUDA is nvidia specific, OpenCL is supported across nvidia, AMD, CPU (and possibly into other things as well)
[14:00] <mfa298> at least Ubuntu supports OpenCL. It's not supported in fedora natively yet.
[14:01] <craag> Hmm I thought OpenCL was AMD, turns out it's not and actually Nvidia has closer ties.
[14:02] <mfa298> although I'm looking forward to what happens in the next couple of fedora releases. OpenCL is in the pipeline and there's a move to make python3 the default
[14:02] <craag> Yeah python3 is becoming the default in the next ubuntu iirc
[14:02] <craag> They jsut didn't want to do it for the LTS
[14:02] Action: craag should probably start coding in py3
[14:03] <mfa298> nvidia have supported both for a while (although I think cuda could give slightly more performance - although that could have changed now)
[14:03] <craag> Yeah from what I've seen, OpenCL on amd cards trumps nvidia
[14:03] <craag> (but that's mainly bit/litecoin mining)
[14:04] <mfa298> I think it depends on what you're doing.
[14:05] <mfa298> I know of one thing where an older nvidia chipset was prefered due to performance.
[14:05] <mfa298> whilst overal performance in newer chipsets was better, the part being used by that software actually got worse
[14:06] <craag> OpenCL coding sounds fun - I just need to find an application that suits it
[14:08] <mfa298> I've only used software that uses GPU's so far, not written any myself. I've also had to get suitable GPU's for various things So this is about as far as my knowledge goes.

[15:01] <mfa298> I tend to use CentOS for most of my VM's although that's partly as that's what I'm used to and for my stuff at home I use NIS+NFS which seems to be a pain getting it working doing it the ubuntu way (i.e. no root use and everything with sudo) which I think is similar to debian as well
[15:01] <mikestir> it's easy enough to set up in debian/ubuntu
[15:02] <mfa298> not as easy as Centos. although I've got that all setup with kickstart which makes life really easy
[15:03] <mfa298> ubuntu doesn't make it that easy. So far I've ignored parts of the installer (creating the local user) and then rescue mode to do the base nis/nfs/automount setup.
[15:03] <mfa298> just fixing idmapd.conf at the moment then it might all work
[15:04] <mikestir> this machine I'm on now uses remote accounts via LDAP. I create a single "local admin" account then the rest is pretty much a case of installing the LDAP pam module and typing in the server details

[16:39] <RalphW0RPK> I have been riding along vicariously and am surprised that B-52 telemetry stopped an hour ago. Just short of a another new duration record if no new data appears.
[16:40] <craag> RalphW0RPK: There's an issue with the GPS, so it drops out when it gets cold. It's recovered each time so far though!
[16:40] <craag> Might have to wait til tomorrow morning
[16:47] <RalphW0RPK> I am quickly looking at the telemetry data set and don't see a similar drop out yesterday or the day before at the same time-of-day.
[16:51] <RalphW0RPK> Sunset at payload coordinates is still ~40min away, an hour and ~40min at the time of the last telemetry frame.

[16:56] <craag> myself: If you can make one that weighs less than 2g...
[16:56] <RalphW0RPK> It is interesting that B-11 duration was 187hr, B-45 was 188hr and B-47 was 190hr. Now Leo has B-52 with ~190hr. Is this a tread worth investigating(?)
[16:57] <craag> RalphW0RPK: He's using hand-made balloons - and probably getting better with the heat sealer :)
[16:59] <craag> So radio silence until B-52 reaches poland most likely
[16:59] <RalphW0RPK> Given Leo's talents with balloons and payloads I am worthy only of kibitzing from the sidelines.

[20:46] <Upu> the resistors its in the datasheet
[20:47] <AndChat|716289> I can not find 4.2
[20:47] <Upu> its been ages since I looked at it
[20:47] <AndChat|716289> VOut must be 5v?

[20:56] <AndChat|716289> VOut value must be set to 5v?
[20:57] <craag> AndChat|716289: The voltage is set by the resistor divider.
[20:57] <MightyMik_> the only antenna i have for this is horizonta; polarization
[20:58] <craag> When the center tap of the resistor divider is equal to Vref, that gives you the output voltage.

[21:07] <aadamson> ah, ok, I'd have confirm my recent changes, but to get to a vmax of 4.2v I think it's a 430k/180k VD network
[21:07] <aadamson> but be advised, if you are going to take your ADC input off that point as well, you'll need to adjust that for impedence changes or the spv1040 won't work
[21:08] <craag> sounds right
[21:09] <craag> Erm why would you want to measure vcrtl?
[21:09] <aadamson> yeah I just looked it's 430k/180k which was a recent change
[21:09] <aadamson> I don't, but I know that LeoBodnar and Upu both pull the ADC input off that point for measuring the vout
[21:09] <MightyMik_> still no signal here : (
[21:09] <craag> Ah for measuring battery voltage
[21:10] <craag> rather than duplicating another divider for that
[21:10] <aadamson> and I talked to LeoBodnar about that and he mentioned that he had to play with resistor values to make the impedance work
[21:10] <aadamson> yes
[21:10] <aadamson> I just use another VD
[21:10] <mikestir> that sounds a bit hairy to me - the input impedance of a SAR ADC is not constant during the conversion
[21:10] <MightyMik_> has cubex popped?
[21:10] <craag> Hmm I'd probably put another one in, so you can smooth it.
[21:11] <craag> Don't really want to mess with a vreg feedback loop - they can be a bit picky
[21:12] <aadamson> in my design, the adc pin impedance is 50k, so I just didn't want to mess everything up, so I used a 430k/180k for the vctrl set and another I think it's 53k/48.7k (or something close) to give me my adc tap point
[21:12] <aadamson> and better match the 50k impedance on the adc pin
[21:12] <aadamson> my vref is 2.07v
[21:13] <DL1SGP> looking at the cubex images I am wondering if humidity in the camera system could create a microscope effect
[21:13] <AndChat|716289> For a 4.2v battery?
[21:13] <aadamson> AndChat|716289: all the above is for a 1S lipo (3.0-4.2v) yes, the output of the spv1040, can't go above 5.x volts anyway
[21:14] <aadamson> there is a complete reference design online
[21:14] <aadamson> http://www.st.com/st-web-ui/static/active/en/resource/technical/document/application_note/CD00292052.pdf
[21:15] <aadamson> that's a complete reference design for a 1S battery charger with up to 5v of PV cell(s)
[21:15] <aadamson> it also explains all the components and why you pick what you pick
[21:15] <aadamson> for what component and what value
[21:16] <AndChat|716289> Are you using page 3 schematic with r1 and r2 values of 430k and 180k?

[21:17] <craag> AndChat|716289: Look at the link aadamson just posted.
[21:17] <craag> Explains in far more detail
[21:17] <aadamson> don't take my work for it however, please follow the examples and calculate it yourself, it's the only way you'll learn
[21:18] <craag> agreed
[21:18] <aadamson> specificially look at page 12/25 and those following for the discussion including how you'd calculate the R values for the vctrl divider
[21:18] <w6yra_satTrack> arko: Are we sure burst has occured? It looks like we're still getting some 32k altitudes,
[21:19] <aadamson> There are 3 primary areas that are critical to any buck/boost controller a) the filter caps, b) the reference voltage divider and c) the inductor
[21:19] <AndChat|716289> Page 7,yes
[21:19] <arko> i dont think it burst
[21:19] <arko> now that im looking at the data history
[21:19] <aadamson> those aren't page, those are sections, the page numbers are in the bottom right/left of each page
[21:22] <rcaron> CARRIER
[21:22] <arko> me too!
[21:22] <arko> w6yra_satTrack: rcaron: i think the balloon popped
[21:22] <rcaron> you know, some balloons keep transmitting after burst
[21:23] <rcaron> :)
[21:23] <arko> haha
[21:23] <arko> yeah
[21:23] <arko> ...
[21:24] <AndChat|716289> How can i test it?
[21:25] <aadamson> how can you test what?
[21:25] <aadamson> do you have it built already
[21:25] <AndChat|716289> I will create a board
[21:25] <fsphil> does it sound bursty?
[21:25] <aadamson> and I hope you have some experience with lithium batteries and charging them?
[21:26] <rcaron> what happened to APRS?
[21:26] <arko> not sure
[21:26] <arko> rcaron: we've had to drop azimuth on our yagi
[21:26] <arko> did you guys as well?
[21:26] <AndChat|716289> If vref is 2.07 it is ok?
[21:26] <aadamson> you can use a AAA battery in place of the PV panel to determine if the spv1040 is functioning, but if you have a high rate of charge going to the lipo, you need to understand that&. LIPO fires are really nasty and will burn in water
[21:26] <rcaron> we still have strong carrier
[21:27] <arko> same
[21:27] <rcaron> bringing the el down anyway
[21:27] <arko> not sure what happen
[21:27] <aadamson> AndChat|716289: you are asking all the wrong questions&
[21:27] <aadamson> vref has nothing to do with the solar controller
[21:27] <rcaron> 434.453.850 or so right now
[21:27] <aadamson> it's the voltage that my controller uses for for it's ADC functions
[21:27] <MightyMik_> is it still transmitting data?
[21:27] <w6yra_satTrack> MightyMik_: No
[21:28] <w6yra_satTrack> MightyMik_: if you were talking about arko's balloon
[21:28] <aadamson> in order for me to read a voltage that is higher than 2.07v I have to build *the right* voltage divider circuit to scale the higher voltage down so a) I can read it and b) it doesn't burn out the pin on my controller
[21:28] <aadamson> every controller will be different depending on what you are using.
[21:29] <aadamson> I'm using an STM32L1 and my voltage in is the same as my vref and I'm running my stm32 on 2.07v
[21:29] <aadamson> the spv1040 doesn't care what the the processor vref is
[21:29] <aadamson> that 430k/180k divider is what sets the max output voltage on the spv1040 to 4.2v
[21:30] <aadamson> if you don't calculate that right, you'll either never charge your lipo battery to max value or you'll overcharge it (which is really bad)
[21:30] <rcaron> still a great carrier

[21:32] <aadamson> *if* you are using a 1S battery, the max voltage that you can charge one to is 4.2v
[21:32] <aadamson> if you are using some other form of battery, then that voltage will be different
[21:32] <aadamson> you really need to work through what it is you are trying to do and how to do it.
[21:32] <LeoBodnar> LiPo chemistry is more complex than that
[21:33] <aadamson> LeoBodnar: yes I know, but I don't *even* want to go there

[21:34] <arko> yeah
[21:35] <arko> it has power and the radio is working
[21:35] <aadamson> AndChat|716289: as LeoBodnar mentioned, there are all kinds of things that will effect your end solution, charge rate of the battery, discharge rate, temperature rating, size, etc. Unfortunately, there is a one size fits all, and you really should understand what you are doing when/if you do it
[21:35] <arko> i think the mcu may have frozen out or the routine got stuck
[21:35] <aadamson> there *ISNT* a one size fits all& bad typing

[21:36] <aadamson> LeoBodnar: I think I've sources some 30x20x5mm 1S cold lipos at 250mah
[21:37] <rcaron> that's why you iterate and try again
[21:37] <rcaron> when's the next one?

[21:38] <aadamson> I don't have an actual way of doing that& but they offered to send me samples, so I figured why not.

[21:51] <LeoBodnar> doing *what*?
[21:52] <LeoBodnar> you have never launched anything
[21:52] <LeoBodnar> balloonish
[21:52] <aadamson> did I say I had?
[21:52] <aadamson> I've only been messing with this *stuff* for a few months
[21:52] <LeoBodnar> [22:50] <aadamson> geez, I've only been doing this for a couple of months :)
[21:53] <aadamson> exactly, I've only been messing with this stuff - controllers, pv, balloons for a few months, and never launched anything yet

[21:53] <aadamson> sorry if you did it in days, I'll do it when I'm ready
[21:53] <aadamson> and as I said, the gate right now is balloons..
[21:53] <didier> is good to have healthy hobbies
[21:53] <aadamson> I ordered some, they aren't here yet
[21:54] <MightyMik> that was strange... did cubex reset?
[21:54] <Upu> Mighty 8 Ball says : it appears to be the case
[21:54] <rcaron> MightyMik: yes
[21:55] <MightyMik> k... looks like i got a page crash right at the same time
[21:55] <fsphil> interseting lens artifacts
[21:55] <fsphil> spelling
[21:56] <fsphil> I wonder if some of that is ice
[21:58] <MightyMik> looks like something froze
[21:58] <rcaron> arko: we're gonna lose it soon
[21:58] <rcaron> S0
[21:59] <arko> kk
[21:59] <arko> well done you guys
[21:59] <rcaron> on the radio and 12db on the fldigi
[21:59] <arko> rcaron: w6yra_satTrack: you guys are awesome
[21:59] <arko> well done tracking :)
[21:59] <arko> gonna have to drive out to westwood and buy you guys beers
[21:59] <rcaron> i'm glad i have to eat my words on transmitting after burst
[21:59] <arko> haha
[22:00] <arko> good to know it reset the mcu though
[22:00] <arko> since it started at image 0 again
[22:00] <rcaron> thats good to know. wasnt sure if the website did the counting or not
[22:00] <rcaron> got too cold?
[22:01] <w6yra_satTrack> Back to carrier
[22:01] <fsphil> image ID is sent by the payload to differentiate between images
[22:03] <MightyMik> images, but no altitude data?
[22:03] <rcaron> carrier dim
[22:03] <rcaron> really faint
[22:04] <rcaron> gone
[22:04] <arko> aww
[22:04] <arko> done and done
[22:05] <arko> well done guys
[22:05] <arko> im gonna go eat now
[22:05] <arko> forgot to do that
[22:05] <Lunar_Lander> is there a page to see the images CUBEX took?
[22:05] <MightyMik> was 597 km out from me... needed LOS to horizon and a better antenna and radio
[22:06] <rcaron> MightyMik: are you K6WCC?
[22:06] <MightyMik> nope... WD8MNV CM87VS Oakland
[22:07] <MightyMik> the ssdv habhub page has pix
[22:07] <w6yra_satTrack> Lunar_Lander: http://ssdv.habhub.org/
[22:08] <Upu> hat off for trying MightyMik
[22:08] <Upu> it can be done at that range
[22:08] <Upu> just
[22:09] <MightyMik> better luck next time, maybe a closer launch
[22:09] <Lunar_Lander> thanks
[22:09] <SpeedEvil> 1000km should be quite doable with a small steered yagi at 30km
[22:10] <Upu> if the yagi is at 30km maybe :)
[22:11] <mattbrejza> thats quite mask
[22:11] <mattbrejza> mast
[22:11] <mattbrejza> planning permission people might have something to say about that

[22:34] <Geoff-G8DHE> makes sense
[22:34] <craag> Not sure why it's limited to 7 bit ascii though
[22:34] <craag> the line of code is:
