[11:38] <fsphil> Bencls: this can be used to find out the fill amount: http://habhub.org/calc/
[11:38] <Vaizki> Bencls, calculate roughly then measure the lift at launch
[11:38] <fsphil> parachute, if you're uncertain then just use a commercial ones
[11:39] <daey> fsphil: would an "until it generates enough lift" work out?
[11:39] <fsphil> um?
[11:39] <daey> i mean fill it until it is roughly in an equilibrium lift==weight. then add a bit more
[11:40] <fsphil> not if you want a decent ascent rate
[11:41] <daey> y it wouldnt be precise, i was just wondering if it would be sufficient.
[11:41] <daey> apparently not
[11:41] <fsphil> well underfill could risk floating / losing the payload
[11:41] <fsphil> overfill will reduce altitude and be a waste of helium
[11:42] nsh- (~lol@wikipedia/nsh) joined #highaltitude.
[11:42] <fsphil> I've done the equilibirum + a bit thing when I'm intending it to float
[11:43] <daey> i still dnont get how floating is even possible with non zero pressure balloons
[11:43] <fsphil> the latex becomes a zero pressure balloon
[11:43] <fsphil> er
[11:43] <fsphil> super pressure
[11:43] <daveake> Try breaking an elastic band
[11:43] <fsphil> you could do zero pressure with a latex too, but it would have to be a big balloon
[11:44] <daey> i just thought that this would lead to more expansion > more lift > balloon rises > pressure drops > more expansion circle
[11:44] <daveake> It's elastic till it's fully extended, then you need to apply a lot more force to break it
[11:44] <Bencls> I need to know how much to order too
[11:44] <daey> i see
[11:45] <fsphil> Bencls: that calculator will give you a rough idea of the amount too, but I'd suggest always getting more
[11:45] <Bencls> Burst Altitude:32273 mAscent Rate:5.00 m/sTime to Burst:108 minNeck Lift:1156 gVolume:1.91 m31906 L67.3 ft3 <-- Which number?
[11:45] <SIbot2> In real units: 3 ft = 0.91 m
[11:46] <daey> a zero pressure balloon doesnt have an advantage if you are going for max height?
[11:46] <fsphil> volume, iirc. been a while
[11:46] <daey> wondering because the last record was iirc. done with a latex balloon
[11:46] <fsphil> the last record wasn't a floater
[11:47] <daey> not saying it was
[11:48] <fsphil> I'm not sure what matters most for max altitude
[11:48] <daey> i just expected that it would be necessary to dump helium on the way up. which the zero pressure balloon can easily do
[11:49] <fsphil> don't think dumping helium would help with altitude
[11:49] <mfa298> except as you dump gas you lose lift so you don't want to dump too much gas.
[11:49] number10 (569e9f74@gateway/web/freenode/ip. joined #highaltitude.
[11:49] <fsphil> unless it's overfilled at launch
[11:49] <fsphil> there's probably a sweet spot for the amount of helium
[11:50] <daey> the airpressure doesnt drop linear, so i assumed you might need more on the bottom than you would at the top. maybe its even the other way around in which case it wouldnt make sense to dump anything
[11:51] <mfa298> my gut instinct is that a ZP probably isn't any better than a normal latex for altitude unless you maybe go for something very big
[11:52] <fsphil> yeah
[11:52] <fsphil> latex is probably not the best material too
[11:53] <mfa298> altitude records seem to be a balance of material weight vs material tension vs volume it can hold.

[12:17] <samme> HI. I was testing how long my battery works, well my lithium batteries are drawning instanteously and I still havent placed them in the freezer. I have used alkaline batteries and they work fine (circuitry seems okay). Why are the lithium ultimate batteries draining so fast?
[12:17] <adamgreig> how fast?
[12:17] <adamgreig> sounds like possibly a fault in your circuit
[12:17] <samme> new cells 6AA 10.77V and within a minute 10:45V
[12:18] <samme> well i used alkaline batteries and they worked for 13 hours
[12:18] <adamgreig> are they in fact still working?
[12:18] <adamgreig> 10.77 to 10.45 is probably just the voltage dropped over the internal resistance
[12:19] <samme> u mean lithium cells?
[12:19] <adamgreig> yes
[12:19] <mfa298> samme: it might be worth finding the datasheet for the batteries as it probably has a discharge curve so you can compare what you see with what it should do
[12:19] <adamgreig> their nominal voltage is 1.5V on the data sheet, so 9V is nominal for a 6x pack
[12:19] <Darkside> the energizer lithiums will drop from 1.8 down to about 1.5-1.6 and stay there for a while
[12:19] <daveake> http://data.energizer.com/PDFs/l91.pdf
[12:19] <daveake> this behaviour (sharp drop then flat) is perfectly normal
[12:20] <samme> phewwww! got me thinking, got it, will test and see how long do they last
[12:20] <mfa298> 0.3v over 6 batteries doesn't sound like that much of a drop either - 0.05v per cell drop on average
[12:23] <adamgreig> yea I'm sure the normal alkaline AAs would drop a loT more
[12:30] <samme> got it. thanks :D

[13:38] <Ian_> arjunnaha the cheapest eps hot wire cutter can be made from a (12V 4A in my case) battery charger and a length of stainless steel wire - such as used by beekeepers to wire frames.
[13:40] <Ian_> To get the right temperature you use a longer length. About 330mm takes around 3A. A car battery can be used.

[13:57] <Bencls> ok, so should I be making it with the assumption that 2/3rds remains (and have that fall at 5m/s) or with the assumption that almost nothing remains?
[13:57] <adamgreig> is 5m/s still ok if my payload is very sharp and quite heavy?
[13:58] <AndyEsser> adamgreig: make the pointy bit go up ;)
[13:58] <adamgreig> alas, you know what they say about things that go up
[13:58] <adamgreig> (must come down)
[13:58] <AndyEsser> if this is for the project I'm thinking
[13:58] <AndyEsser> then you just need a bigger engine to achieve orbit ;)
[13:58] <AndyEsser> and thus, doesn't need to come back down, from our relative frame of reference of "down"

[16:52] <SpeedEvil> batteries recover some voltage when unloaded
[16:52] <samme> but 1V seems alot, doesnt it?
[16:53] <mfa298> are you testing the batteries in the same setup each time. whilst powering the pi, same temperature etc.
[16:53] <SpeedEvil> samme: nope
[16:54] <samme> temperature did defer
[16:54] <samme> and the total duration
[16:54] <mfa298> samme: is this still the 6 batteries you had earlier, if so that's about 0.2V / cell which isn't that unreasonably if your going from pi under load in the freezer to batteries not loaded at room temperature

[17:39] <david5652323> Hi guys
[17:40] <david5652323> I have a question on decoding telemetry with dl-fldigi.
[17:40] LeoBodnar (LeoBodnar@host-2-100-196-160.as13285.net) left #highaltitude.
[17:41] <david5652323> My setup is a Pi-in-the-Sky transmitting from my rooftop, RTTY on 70cm and APRS on 2m.
[17:41] <david5652323> I am decoding with an rtl-sdr dongle, running GQRX into dl-fldigi.
[17:42] <david5652323> I can decode both RTTY and APRS. APRS I cannot verify, but RTTY doesn't decode reliably.
[17:42] <david5652323> Out of 80 packets I've decoded one good one (green).
[17:42] <david5652323> Any pointers on where to look?
[17:45] <edmoore> what antennas are you using at each end david5652323 ?
[17:45] <M0RJX> is htere a simple way to upload a sentance to habitat I'm not using dl-fldigi?
[17:46] <M0RJX> Web frontend perhaps :-) Curl it in ?
[17:46] <david5652323> At the PiTS-side a small groundplane for 70cm and a 2m small mobile whip.
[17:47] <david5652323> At the receive end the little whip antenna that came with the rtl-sdr dongle.
[17:47] <edmoore> and on the receiver side?
[17:47] samme (8258f042@gateway/web/freenode/ip. left irc: Ping timeout: 264 seconds
[17:48] <edmoore> do you know if you have anything inteferingy nearby the dongle?
[17:48] <edmoore> ethernet-over-powerline or anything else similarly obnoxious?
[17:49] <david5652323> Nope, it's plugged into a laptop and there's a transceiver nearby but that's just monitoring 144.800...
[17:49] <david5652323> Don't see much interference in GQRX either.
[17:49] <edmoore> could you post a screenshot of what you are seeing in dl-fldigi during rtty transmission?
[17:51] <david5652323> GQRX: https://s4.postimg.org/yaqlyu6kt/Screenshot_from_2016_08_15_19_48_02.png

[17:52] <edmoore> that looks pretty horrendous in fldigi
[17:53] <edmoore> well, turn off sql for one
[17:53] <edmoore> bottom right
[17:53] <edmoore> and see if that helps
[17:54] <david5652323> Nope, didn't improve much..
[17:54] <david5652323> What do you mean with "looks pretty horrendous in fldigi"?
[17:54] <david5652323> Signal level too low?
[17:55] <edmoore> yeah
[17:55] <edmoore> should be two fairly clean peaks
[17:55] <edmoore> rather than a general yellow smudge
[17:56] <edmoore> i don't use gqrx so don't know enough to know if it's a settings problem with that
[17:56] <david5652323> Where to look for improvements? I guess with the TX up on my roof into a ground plane and with the stock antenna that came with the rtl-sdr dongle it should get enough signal.
[17:56] <david5652323> I am struggling a bit with setting audio levels so maybe it's an issue on the audio side.
[17:57] <david5652323> Looking at the decoding with dl-fldigi page the screenshot looks like a similar smudge http://www.pi-in-the-sky.com/data/uploads/tracking/dl4.jpg
[18:06] <david5652323> I decreased the LNA gain and disabled AFC in GQRX, now it's beginning to decode SSDV packets. I guess it's a GQRX reception issue after all...
[18:08] <david5652323> I am beginning to douobt if I am overdriving my RX setup because my TX is so close...

[19:01] <fsphil> the second decimal point is a bit odd
[19:01] <fsphil> might be better as a comma

[19:02] <M0RJX> the final digit on;y gets change by AFC as far as I can see
[19:02] <daveake> If I get tidy it up in time, I'll run dl-fldigi decoding on the chase-car Pi for Wednesday's flight
[19:03] <M0RJX> ssdv?
[19:03] <daveake> well it can do but I'll probably only tx telem
[19:04] <daveake> If I run all 3, it'll be ssdv on 868 lora, and telem on 868/434 lora + 434 rtty
[19:04] <M0RJX> What do you need to tidy?

[19:24] <fsphil> not loading either
[19:26] <daveake> https://dl.dropboxusercontent.com/u/368443/HAB/LoadYouDamnImage.jpg
[19:26] <craag> works here
[19:26] <craag> hmm double party balloon
[19:26] <daveake> yeah
[19:26] <fsphil> weird. imgur link still broke here but the dropbox one is fine
[19:26] <daveake> ok

[19:33] <daveake> yeah
[19:36] <fsphil> daveake: suggestion, rename the git version of gateway.txt to gateway.txt.example
[19:36] <fsphil> and add gateway.txt to .gitignore
[19:36] <fsphil> so local changes don't get detected/committed/overwritten

[19:39] <fsphil> ah there's already a gateway-sample.txt. just need to remove gateway.txt
[19:42] <daveake> yeah I missed that last bit
[19:42] <daveake> so the file came back
[19:42] <mfa298> I think there's a way to comit a config file with the right name, although I can't remember how off hand, the .sample version tends to be easier

[19:56] <M0RJX> daveake, just a thought your sha for the document id will it be different on every gw or the same
[19:56] <daveake> Yeah needs to be different
[19:56] <M0RJX> Thinking about the lack of decode counts?
[19:56] <daveake> This has been mentioned :-)
[19:56] <M0RJX> Doh too late as ever
[19:56] <daveake> :-)
[19:57] <M0RJX> Was looking at the code earlier and saw how you set the id and thought this might be the problem
[20:04] <daveake> Thanks fsphil. I like this open source thing with others doing my work for me :-p
[20:06] <fsphil> currently doing anything but actual work
[20:09] <daveake> Good plan
