[08:51] <AndyEsser> Airspy and Pi Zero arrived yesterday :)
[08:51] <AndyEsser> time to get them working together in a little box that I bolt to the outside of the house
[08:53] <SpacenearUS> New vehicle on the map: 03ALMA-3 - 12https://tracker.habhub.org/#!qm=All&q=ALMA-3
[08:55] <PE2BZ> AndyEsser and label it Airspi Zero ;-)
[08:55] <PE2BZ> Do they have to join one antenna ?
[08:56] <AndyEsser> I only have one antenna
[08:58] <Vaizki> I don't think pi zero has the oomph to work with 6Msps i/q streams?
[08:59] <PE2BZ> I assumed the Pi Zero to be completed with a lora tracker ;-)
[08:59] <PE2BZ> And the Airspy with an USB cable.
[09:00] <AndyEsser> Airspy USB into Pi
[09:00] <AndyEsser> Vaizki: have to wait and see :P
[09:00] <AndyEsser> apparently it can manage the full 20 Msps according to an article I just saw
[09:02] <Vaizki> Raspi 2 and Airspy Mini were not working out for me, libairspy was saturating one core completely and losing data
[09:03] <Vaizki> raspi3 works ok.. I guess with a raw stream the raspi2 would have managed but I needed I/Q
[09:03] <AndyEsser> Will just have to see :)
[09:05] <AndyEsser> Worst case scenario the Airspy goes into my PC at home and I use the Pi for something else
[09:09] <daveake> I'd go Pi3 for something like that - built in LAN/WLAN, and more CPU power in case you need it.

[09:09] <daveake> With the Zero you need a USB hub just to get a net connection + airspy
[09:11] <gonzo_> there is the bananna pi, that has a direct eth and sata if on board, not via the usb
[09:11] <gonzo_> pjm has been using those, may be able to advise

[09:14] <fsphil> congrats
[09:15] <daveake> Do you have pear ?
[09:15] <daveake> a
[09:17] <PE2BZ> lets jam ;-)
[09:17] <PE2BZ> Or make a nice Pi
[09:19] <gonzo_> though that having the separate ETH would free up usb bandwidth for the airspy
[09:21] <AndyEsser> daveake: o weird.... thought the Pi Zero had built in wlan
[09:22] <AndyEsser> time to order a Pi 3 :P
[09:22] <fsphil> it would be nice if it did
[09:24] <AndyEsser> note to self... when tethering laptop to phone... don't get confused when laptop loses connection when I pop to the loo...
[09:26] <gonzo_> it's when you allow a group of people to tether, then you walk off. Just as you are about to get out of sight you hear them all wow and throw their hands up
[09:26] <AndyEsser> haha
[09:27] <gonzo_> has happened at the radio club, where there are a bunch of old men too tight to have a phone on contract
[09:33] <pjm> the banana pi is excellent it have gig-e built in and is quick

[10:52] <torntrousers> Hello, me again with more questions :)
[10:53] <torntrousers> I wonder about the tracker payload message format for LORA transmissions.
[10:53] <torntrousers> I understood its good to keep the LORA packet small and so send just a few fields in a binary format.
[10:53] <torntrousers> But Habitat requires an ascii string like $$test1,203,11:32:32,51.586685,-0.102161,21*25
[10:53] <torntrousers> So if the payload transmission is in binary then something like the receiving gateway has to convert that to the ascii sentence.
[10:53] <torntrousers> So does the gateway just have to have hardcoded what the payload binary format is so it knows how to do that conversion to ascii, or is there somewhere to register the binary format so the gateway can look it up to find what fields it contains?
[10:54] <rharrison> torntrousers, you need to decode it to text
[10:54] <torntrousers> "you" who?
[10:54] <rharrison> You can send what ever you like and provided you know how to decode it then a small change to the gateway can be made to unwrap the binary format
[10:55] <rharrison> torntrousers, there is no binary to text conversion
[10:56] <torntrousers> so its only my lora receiving gateway that knows the binary format and is going to be able understand the transmisson?
[10:56] <rharrison> Correct
[10:56] <torntrousers> i see
[10:57] <rharrison> Though you could write an interface for binary to text conversion and get dave to include it in the gateway code :-)
[10:57] <rharrison> Then everyone could read this from either habitat or somewhere else for your payload
[10:57] <torntrousers> i'm trying to write my own gateway code that runs on an esp8266
[10:58] <rharrison> Cool jcoxon play with those too
[10:58] <rharrison> plays
[10:58] <torntrousers> i hoped someone might have already done it so i could use that, but not been able to find anything
[10:58] <rharrison> Such is life :-(
[11:00] <Geoff-G8DHE-M> Well all the code is on github for daveake PITS and the gateway so its not much of a problem https://github.com/PiInTheSky

[11:08] <SpacenearUS> New position from 03IV3SRD-11 after 0310 hours silence - 12https://tracker.habhub.org/#!qm=All&q=IV3SRD-11
[11:08] <daveake> Binary -> ASCII in the gateway is a pain as it'd be payload-specific. There's been talk of habitat handling binary packets.
[11:10] <torntrousers> Is it better then to have the payload packect just contain the ascii text and not use binary?
[11:11] <Geoff-G8DHE-M> what's not binary about ASCII ?
[11:11] Mack (~Mack@unaffiliated/mack) left irc: Ping timeout: 272 seconds
[11:11] <Geoff-G8DHE-M> Its not compressed if that's what you mean ?
[11:12] <gonzo_> the only good reason for having ascii at all is that it is human readaable
[11:12] <torntrousers> maybe 'binary packet' isn't the right name? i'm new here and don't know all the terms. I mean have the payload send something like:
[11:12] <AndyEsser> some humans
[11:13] <torntrousers> struct TBinaryPacket { uint8_t id; // uint16_t t; uint16_t counter; float latitude; float longitude; int32_t alt; }
[11:13] <fsphil> please don't use float :)
[11:13] <gonzo_> but there seems to be huge amounts of ascii in the computer world. Which I can only see as, being easy for developers, but too lazy to swap out for binary afterwards
[11:14] <AndyEsser> not on an AVR
[11:14] <AndyEsser> O hell 3kb soft-float library!
[11:14] <AndyEsser> hello*
[11:14] <fsphil> O hell works too :)
[11:14] <gonzo_> I wonder how much you could shrink (or speed up) the internet infrastructure if you were to get rid of readable text for M2M comms
[11:14] <AndyEsser> well HTTP 2 has a binary mode
[11:14] <AndyEsser> which should help
[11:14] <fsphil> probably not that much
[11:15] <AndyEsser> since each HTTP request has so much nonsense verbose ascii
[11:15] <fsphil> given that most of the data is probably mpeg, jpeg or gzipped
[11:15] <AndyEsser> fsphil: payloads are gzipped
[11:15] <AndyEsser> not headers
[11:15] <fsphil> that's only a tiny part of the data
[11:16] <AndyEsser> our headers are 17kb here at work atm
[11:16] <AndyEsser> *cries*
[11:16] <fsphil> ok, that's usually only a tiny part of the data :)
[11:16] <fsphil> are you sending images in the headers?
[11:16] <AndyEsser> True, but imagine how many request/responses there are on modern webpages
[11:16] <AndyEsser> where the response payload is maybe a couple hundred bytes
[11:16] <AndyEsser> fsphil: no, authorisation tokens that contain more information than they should
[11:16] <fsphil> yikes
[11:17] <AndyEsser> entire trees that link entities and things
[11:17] <fsphil> sounds like something that would be better being stored server side
[11:17] <AndyEsser> fully agree
[11:17] <AndyEsser> but the FE needs access to it as well
[11:17] <AndyEsser> so my suggestion was each 'screeen' makes a single call to the BE to get that data
[11:17] <fsphil> I worked on a .net website once (just once). it send the entire state to the client each time
[11:17] <AndyEsser> not pass it around in a header
[11:17] <AndyEsser> where we can easily have dozens of requests per screen

[11:20] <AndyEsser> tbh my pi came with a wifi dongle
[11:20] <AndyEsser> but obviously means no airspy
[11:21] <torntrousers> Isn't the thing with LORA that its slow so if the payload can send its location in 15 bytes instead of 50 bytes than its send much faster and so it can send its location more often in the duty cycle restrictions?
[11:21] <fsphil> does the pi have enough usb bandwidth to stream airspy data over wifi?
[11:22] <AndyEsser> guess we'll find out :P
[11:23] <russss> fsphil: hmm, is the Pi3's wifi on the USB bus?

[11:25] <Geoff-G8DHE-M> torntrousers, Have you done the arithmetic for 50Baud RTTY with a 50Byte telemetry message, against LoRa at its slowest ?
[11:26] <craag> pi3 wifi is on the sdio
[11:26] <craag> they've still got the same 4-port usb + ethernet chip hanging off the single soc usb port
[11:27] <AndyEsser> I might just butcher an old netbook I have
[11:27] <AndyEsser> take the mobo out and mount that in a waterproof case
[11:27] <torntrousers> No. Are you suggesting I should just send plain text and not use binary?
[11:29] <daveake> You might want to try the lora calculator to see what speeds you can get
[11:30] <daveake> You'll easily get better speed than rtty for the same range
[11:30] <Vaizki> 17kB of headers? that's... awful. I'm doing a web service and stressed out about our 200-300 bytes .. :D
[11:30] <torntrousers> "the lora calculator"?
[11:31] <daveake> the lora calculator
[11:31] <daveake> It's on the semtech web site
[11:31] <daveake> Amongst other things it gives you the data rate for different bandwidths and modes
[11:32] <fsphil> I've never actually checked the size of the headers from my web serivce
[11:32] <fsphil> bet it's awful...
[11:32] <AndyEsser> just loading tracker.habhug.org takes 130 requests and 1.2MB
[11:32] <Vaizki> 95+% of this service's responses fit in a single tcp frame with MTU 1500 ..
[11:33] <Vaizki> that's the way I like it ;)
[11:33] <fsphil> nice!
[11:33] <AndyEsser> err habhub* even
[11:33] <Vaizki> well there's also up to 50 000 tps hitting it
[11:34] <Vaizki> so it's not just for style
[11:34] <gonzo_> I had some gasps from people use to internet packet sizes, when talking HAB downlinks. They just assumed that when I said 50db, I must have meant 50k bd. And seemed to refuse to be corrected
[11:34] <AndyEsser> lol
[11:35] <torntrousers> @daveake - isn't there a usual or common approach to this? I'm just trying to work it out from code I can find on the Internet, like your FlexTrack code which sends a binary payload right? https://github.com/daveake/FlexTrack/blob/master/FlexTrack.ino#L164
[11:35] <daveake> It's an option in the code
[11:35] <daveake> I've not needed to use it
[11:35] <daveake> Even for the repeater flight (3 balloons chatting to each other) I had a 20-second update period
[11:36] <torntrousers> Oh! I see. So I can just send plain text? That would be so much easier
[11:36] <daveake> That used ASCII but was still (just) within the 10% max duty cycle allowed for the band/bandwidth
[11:36] <daveake> for a single flight, same parameters, you could do 7-second updates within the 10% rule
[11:37] <torntrousers> what would be a normal spreading factor and bandwidth to use?
[11:38] <daveake> Most flights use 20.8kHz because that sites within a 25kHz channel, allowing continuous transmission.
[11:38] <daveake> 88888888888888888

[11:40] <AndyEsser> gonzo_: 85%....
[11:40] <AndyEsser> think porn might hvae slightly more than 15%
[11:40] <gonzo_> yes a well proven figure, qualified by my making it up
[11:41] <fsphil> I worry about the overlap
[11:41] <gonzo_> there may be a cat-pron in there too
[11:41] <gonzo_> heheh snap
[11:41] <gonzo_> if it helps, you think of cats watching porn.
[11:42] <torntrousers> Is thats from page 19 of IR2030? https://www.ofcom.org.uk/__data/assets/pdf_file/0028/84970/ir_2030-june2014.pdf
[11:42] Action: PE2BZ thinks about cats and Latex
[11:43] <torntrousers> I was trying to understand what the different rows meant.
[11:43] <torntrousers> Does that third row mean you can transmit continuously if you use less that 25k bandwidth?
[11:43] <daveake> If there's no duty cycle limit then you can tx 100%
[11:44] <torntrousers> so the first row which says duty cycle limit 10% is only if you#re using > 25k bandwidth?
[11:45] <daveake> Yeah you just need to comlpy with 1 row
[11:45] <torntrousers> i see. thanks

[12:48] <AndyEsser> gah... new version of Sutton being released on December 1st, 2016....
[12:48] <AndyEsser> do I wait...
[12:48] <SpeedEvil> http://www.ewp.rpi.edu/hartford/~ernesto/S2013/EP/MaterialsforStudents/Lee/Sutton-Biblarz-Rocket_Propulsion_Elements.pdf
[12:48] <AndyEsser> how much can really change...
[12:48] <SpeedEvil> (old version)
[12:48] <SpeedEvil> $150 to mars.
[12:48] <SpeedEvil> (yes, I know)
[12:49] <AndyEsser> ?
[12:49] <SpeedEvil> SpaceX has alleged that their new carbon-fibre/paper rocket will get $150/kg to mars.
[12:49] <AndyEsser> ah
[12:50] <SpeedEvil> Which would be very awesome, but it's very much a paper rocket - though the engine has been tested some.
[12:50] <edmoore> everyone who claims price/kg costs sans context should be shot in the face twice from now on
[12:50] <edmoore> it's so confused and bullshitty
[12:52] <edmoore> it makes people think that they can build a 1kg, 1U cubesat and have it launched for £10,000 say
[12:52] <craag> I've got 100g, here's 15 bucks, can we do it tomorrow?
[12:52] <edmoore> cos they read some rocket is 10,000/kg
[12:52] <edmoore> when Mr Arianne or mr Nasa has got themselves up from having fallen off the chair laughing at your stupidity they will explain to you that it doesn't work like that
[12:53] <edmoore> i will sell you a tudor brick for £20!
[12:53] <edmoore> all you have to do is buy my tudor house for £1M and it's yours
[12:54] <gonzo_> also all the qualification and documentation that is added on before that 1kg is accepted
[12:54] <gonzo_> and the extra kg's of launch adaptor
[12:55] <AndyEsser> you mean I can't homebrew 1kg to orbit for £10,000?
[12:55] <AndyEsser> :(
[12:55] <craag> no, but I hear you can send up an rfm22 for $50
[12:57] <SpeedEvil> And yes - the figure was in context, but is widely quoted out of it, there were lots of caveats that are usually missed.
[12:57] <SpeedEvil> 10* the launcher cost per kilo doesn't mean it's more expensive.
[12:57] <SpeedEvil> (for a given payload)
[12:57] <edmoore> arianne 5 is cheaper than most of these newspace launchers
[12:57] <edmoore> per kg
[12:57] <edmoore> for example
[12:58] <gonzo_> I forget whjat funcube1 cost? 150k? And that was with the builder company doing lots at cost
[12:58] <edmoore> but that number is not relevent
[13:00] <edmoore> if you manage to get your cubesat up for £10k it's presumably because some space agency is footing the other £100k of overhead
[13:03] <craag> ESA'll do it for unis for only £10k of your finest tree and ink
[13:05] <AndyEsser> sod it, Rocket Propulsion Elements ordered - will potentially replace it in December
[13:08] <AndyEsser> I just remembered the whole: git clone <repo> folder syntax!
[13:08] <AndyEsser> woo
[13:12] <SpeedEvil> :)
[13:14] <edmoore> replace RPE in december?
[13:14] <edmoore> wha?
[13:15] <Laurenceb_> old book suffered bit rot?
[13:16] <Laurenceb_> talking of which, the electron rocket looks interesting
[13:16] <Laurenceb_> hopefully it will be launching quite soon
[13:18] <SpeedEvil> I'm charged up about it.
[13:18] <number10> you are being negative again
[13:19] <SpeedEvil> Well, you have to be negative about the electron rocket when near it or it won't get off the ground
[13:21] Action: Laurenceb_ wonders how much kit they ordered from hobbyking
[13:21] Action: SpeedEvil hopes for lacks of explosions from all of the new entrants.
[13:21] <SpeedEvil> Laurenceb_: I've got the 5000lb engine coming on friday, it was only $130
[13:21] <SIbot> In real units: 5000 lbs = 2268.0 kg
[13:23] <Laurenceb_> car engine?
[13:23] <SpeedEvil> Laurenceb_: I was attempting to imply that hobbyking sold rocket engines.
[13:23] <Laurenceb_> oh
[13:24] <Laurenceb_> no they sell lipos and brushless motors, what electron uses for its pumps
[13:25] <AndyEsser> edmoore: yes, apparently new version out in December
[13:26] <SpeedEvil> Laurenceb_: makes sense with the ridiculous 2 minute power
[13:26] <Laurenceb_> yeah, it looks fairly competitive on paper
[13:26] <Laurenceb_> way better than pressure fed
[13:28] <edmoore> i am pretty sure the new version will contain nothing of any relevence to you if you're serious about designing engines
[13:29] <AndyEsser> edmoore: that's why I decided to get it now and not wait
[13:29] <AndyEsser> how much has really changed... :)
