[00:00] <lz1dev> not really
[00:00] <Randomskk> what other things did c.b. say jon?
[00:00] <Randomskk> things about linux and building android kernels and stuff
[00:00] <mattbrejza> 'WiFi downlink'
[00:00] <Randomskk> and makefiles?
[00:00] <gonzo_> not sure if this one has amsat involvememnt. But we have been involved with a nukber of student sats, because they usually hit a reef when it comes to the comms subsystems
[00:00] <mattbrejza> error correction?
[00:00] <jonsowman> the wind affecting speed over ground floored me
[00:00] <mattbrejza> Randomskk: checksum
[00:00] <Randomskk> oh my god the wind affecting speed over ground
[00:00] <fsphil> !?
[00:00] <Randomskk> or getting the unix epoch wrong
[00:00] <jonsowman> I was asking if the flight computer could write the speed over ground to the telem database
[00:00] <Randomskk> then defending yourself by saying it depends on what UTC you're using
[00:01] <jonsowman> so that some of the apps could put the speed on their photos or whatever
[00:01] <jonsowman> and they were like "well no because that's affected by the wind isn't it? and we won't know about the wind when we're in space"
[00:01] <jonsowman> :|
[00:01] <lz1dev> thats kinda true
[00:01] <jonsowman> is it?
[00:02] <Randomskk> it's not true
[00:02] <lz1dev> the second part that is :D
[00:02] <mattbrejza> we won't know about the wind when we're in space"
[00:02] <Randomskk> oh well
[00:02] <jonsowman> oh, yes, that bit is true
[00:02] <Randomskk> oh their entire radio downlink system
[00:02] <jonsowman> but like
[00:02] <jonsowman> wtf
[00:02] <Randomskk> was monstrous
[00:02] <Randomskk> also isn't it all x.25
[00:02] <Randomskk> after the udp-over-i2c bit
[00:02] <jonsowman> HDLC I think
[00:02] <Randomskk> or his totally custom and stripped down android kernel
[00:02] <Randomskk> with memory triplication
[00:02] <jonsowman> oh yes
[00:03] <jonsowman> pretty sure that's optimal
[00:03] <jonsowman> I won't mention names but apart from being monumentally stupid, this person is extremely hard to argue with due to his inherent confidence in his own non existent knowledge
[00:04] <lz1dev> i'd love to checkout the feasibility study
[00:04] <jonsowman> it'd just make you cry
[00:04] <jonsowman> also they tweeted themselves earlier
[00:05] <jonsowman> https://twitter.com/SurreyNanosats/status/299612933552480257
[00:05] <jonsowman> D:
[00:05] <craag> So.. they found the phone won't work below -5. So they are using 'processor intensive routines' to keep it warm :/
[00:06] mfa298 (~mfa298@gateway.yapd.net) left irc: Ping timeout: 248 seconds
[00:06] <jonsowman> that's kind of stupid, but everything's relative
[00:06] <jonsowman> and relatively, that's genius
[00:06] <fsphil> and.... this is actually flying?
[00:06] <fsphil> into space?
[00:07] <jonsowman> unfortunately

[00:07] <mattbrejza> dw, itll burn up in a few months
[00:07] <lz1dev> is there a prime95 app for anrdoid?
[00:08] <jonsowman> it'll probably find a Mersenne prime but we'll never know because the downlink will be broken
[00:08] <Randomskk> haha
[00:08] <craag> lol

[00:12] <fsphil> is this the entire satellite, or just a part of it?
[00:12] <fsphil> be nice to think if that all goes wrong, at least something will work
[00:12] <jonsowman> that's all of it
[00:12] <jonsowman> in that paper
[00:13] <fsphil> you know, it could all work
[00:13] <jonsowman> even if it does
[00:14] <jonsowman> it doesn't stop huge portions of the design and engineering being stupid and ridiculous
[00:14] <Randomskk> and way way way over schedule
[00:14] <fsphil> true
[00:14] <Randomskk> this should have burnt up already
[00:14] <fsphil> and if it does work, it may encourage more stupid
[00:14] <craag> but but but, it has a 1000MHz ARM Processor! That's more than 100x better than Delfi C3!
[00:14] <jonsowman> we should have taken our chance whilst we were there Randomskk
[00:14] <craag> :P
[00:14] <fsphil> haha
[00:14] Action: jonsowman puts a flamethrower on the CUSF expenses
[00:15] <Randomskk> jonsowman: torched the whole place?
[00:15] <Randomskk> I won't say anything more on a public channel ;)
[00:15] <jonsowman> :D
[00:15] <fsphil> remote inspection of a rocket body
[00:15] <fsphil> that'll be tricky
[00:15] Action: Randomskk starts making the playlist
[00:16] <jonsowman> :D
[00:16] <Randomskk> hmmm
[00:16] <Randomskk> I have some french music, I guess that counts
[00:16] <Randomskk> actually I bet it's secretly canadian, better check
[00:17] <jonsowman> close enough
[00:17] <Randomskk> we have enough dricving to do that I guess I can just stick whole albums on
[00:19] <jonsowman> around 8 hours driving
[00:19] <jonsowman> not including tunnel
[00:19] <Randomskk> :|
[00:19] <jonsowman> the longest chunk is 2 hours though
[00:19] <jonsowman> which is nice
[00:20] <Randomskk> right I am terrible at making playlists
[00:20] <fsphil> shame the raspberry pi wasn't out sooner, they could have flown that .....
[00:20] <Lunar_Lander> Daft Punk actually was from France
[00:20] <Lunar_Lander> :P
[00:20] <Lunar_Lander> just an info
[00:20] <fsphil> they're not actually robots either
[00:21] <Lunar_Lander> xD

[00:21] <fsphil> they've a PIC24 controlling the radio
[00:23] <fsphil> could they not have done that directly from the flight computer
[00:23] <jonsowman> of course they could

[00:34] <fsphil> I browsed through it pretty quickly, I didn't see any mention of security. is the I2C bus basically being presented open on the radio?
[00:34] <jonsowman> oh they did say something about that
[00:34] <jonsowman> Randomskk: can you remember?
[00:34] <jonsowman> pretty sure someone asked that question
[00:34] <jonsowman> /dev/sda1 451G 169G 260G 40% /
[00:35] <jonsowman> ignore
[00:35] <mattbrejza> smooth
[00:35] <jonsowman> shush
[00:35] <Randomskk> no
[00:35] <lz1dev> in the end they can send a second phone with the mission to ad-hoc with the first one
[00:35] <Randomskk> the i2c is only internal aiui
[00:35] <lz1dev> and run firmware update
[00:39] <lz1dev> wifi ad-hoc satelite net
[00:39] <lz1dev> hmm
[00:40] <fsphil> right, the I2C is not exposed
[00:41] <fsphil> "In order that such activities can be orchestrated from the ground, the OBC system also relays commands and telemetry between the hardware attached to the I2C bus on the spacecraft, and the ground, effectively making itself transparent in this respect."
[00:41] <fsphil> that's what made me think it was

[09:57] <fsphil> 8 bit always an unusual choice for text-only payloads

[09:58] <mattbrejza> i think
[09:58] <fsphil> yea I think that's right
[09:58] <jonsowman> yeah
[09:59] <costyn> outside of HAB I've never used anything else than 8n1
[09:59] <costyn> console ports on network equipment always uses that too
[10:00] <mattbrejza> 7bit acsii is bad enough, so meh add another bit :P
[10:00] <jonsowman> joey is still 8 bit
[10:00] <jonsowman> I'll change it one day
[10:00] <jonsowman> costyn: yeah, 8N1 is just The Standard usually
[10:00] <zyp> I've both used 9n1 and 8-bit with parity for various stuff
[10:00] <fsphil> newer fldigi has problems with ascii values > 127

[11:06] <Hix> oh costyn, found a UK agent for that 8020 componentry I was using for the CAD for the slider
[11:06] <Hix> unfortunately as ususal in the UK $1 translates to £1
[11:06] <costyn> Hix: as always :)
[11:07] <Hix> but reckon I can get a 2m rail and carriage done for ~£65
[11:07] <Hix> plus all the motors and controller stuff
[11:08] <Gadget-Mac> Hix , slider ?
[11:08] <costyn> Hix: cool, tried the stepper motor last night, not much joy... not doing what I expected and my darlington array was getting too hot to touch, probably not good
[11:08] <Hix> Gadget-Mac, a timelapse slider [dolly] http://i.imgur.com/6RUbNww.png designing it at the moment

[11:09] <Gadget-Mac> Hix, I assume you're aware of http://www.makerslideeurope.com/
[11:10] <Hix> yeah, but I'd already started this, and the makerslide seemed a little samll

[11:39] <Hix> no ideas yet costyn
[11:39] <Hix> reading up onm the best ways
[11:40] <Hix> all info useful for me
[11:40] <costyn> Hix: there's dedicated controller boards aplenty, but I thought I'd learn more and it'd be cheaper if I just used darlington or other motor driver ICs
[11:40] <Gadget-Mac> I'd take a look at these for stepper drivers http://proto-pic.co.uk/drv8825-stepper-motor-driver-carrier-high-current/
[11:41] <costyn> Gadget-Mac: that's pretty cheap
[11:42] <Gadget-Mac> Yes, nice thing about those over the previous version, http://proto-pic.co.uk/a4988-stepper-motor-driver-carrier/ is that you get the fault line brought out so can detect stall / overcurrent
[11:42] <Hix> i've got a couple of H293's in the bin [think right pt#]
[11:43] <costyn> L293D
[11:43] <Gadget-Mac> I'm all for understanding how they work, H-Drivers, and stepping sequences, but why have all the hard work when something at that price makes it easy
[11:43] <costyn> Hix: H-bridges
[11:43] <costyn> ?
[11:43] <Hix> but a proper controller for ramping up and down
[11:43] <Hix> yup thats it

[11:46] <Hix> I was looking at pololu stuff, mainly because they can be bothered to include a proper eng dwg with their info online, good when you're designing it in CAD

[11:57] <Hix> http://proto-pic.co.uk/stepper-motor-bipolar-200-steps-rev-35x28mm-10v-500ma/ looks like a decent motor, need to do the calcs for holding torque though
[12:05] <Laurenceb> i used a my3002

[12:05] <Laurenceb> ASTROSYN motor
[12:10] <Hix> Laurenceb, have you built a timelapse dolly then?
[12:11] <Laurenceb> no, a linear actuator for antoher device
[12:11] <Laurenceb> but its very similar kit
[12:11] <Hix> ah ok
[12:12] <Hix> just wondering what you used ofr the linear bearing. rollrs?
[12:12] <Hix> rollers
[12:12] <Laurenceb> well - stm32f4discovery with polulu board, then my3002 motor
[12:12] <Laurenceb> i used custom brass leadscrew
[12:12] <Laurenceb> then a telescopic thingy i made from alu tube
[12:12] <Hix> ahh - bit more accurate than my needs then :)
[12:12] <Laurenceb> lots of lathe work
[12:13] <Laurenceb> yeah about 10micron accuracy
[12:13] <Hix> oh only slightly then ;p
[12:13] <Laurenceb> and ~1m/s max speed, and 30KgF :P
[12:14] <Laurenceb> it can also pull 5G on the end
[12:14] <Laurenceb> but doing stuff like that will kill the motor and driver if you go to more than ~30% duty cycle

[12:19] <Hix> probably good to get a grasp on how it all works
[12:21] <Hix> the only problem is I can see this all turning into a GOTO mount for the scope

[13:49] <Hix> *Costyn
[13:50] <costyn> Hix: thanks
[14:00] <Hix> what are the limitations of using the L293D with an arduino?
[14:00] <Hix> oh man!!!!
[14:01] <costyn> Hix: none with the arduino, there are some current limits of course
[14:01] <Hix> Just found out SKPang are about 6 miles away
[14:01] <Hix> is the main one the timing limit based on the ATMEga's speed?
[14:02] <costyn> Hix: errr out of my league :) if you want to control speed you can send it PWM, but with a stepper, not sure what you're asking actually
[14:02] <Hix> bugger - they only sell onine - annoying
[14:03] <Hix> thought arduino had paoblems with microsecone timing - if at all it can
[14:03] <costyn> Hix: where do you need that?
[14:03] <fsphil> the avr can do very precise timing if you need it
[14:03] <Hix> I don't yet. havent even got the stepper yet
[14:04] <costyn> Hix: but unless you need your motor to go very fast, do yu need microsecond timings?
[14:04] <Hix> avr as in ATMega328?
[14:04] <costyn> Hix: avr is the atmega 328 architecture
[14:04] <costyn> Hix: so yes
[14:04] <Hix> I was thinking in terms of telescope slewing
[14:04] <Hix> oh ok. thought it was limited. no worries then
[14:05] <fsphil> the arduino's delay commands are not terribly precise
[14:05] <costyn> as seen in rtty bitbanging to get 50 baud :)
[14:06] <fsphil> exactly
[14:06] <fsphil> I examined the timing in one flight (no names) and it was all ove the place :)
[14:06] <Hix> ahh that's where i went wrong then, delay
[14:06] <costyn> i feel so smart that I actually understand that now :)
[14:07] <fsphil> but thankfully fldigi is surprisingly tolerant of timing errors
[14:07] Action: fsphil is guilty of this too
[14:07] <Hix> how would you measure that without a scope or can you not
[14:07] <costyn> Currently, the largest value that will produce an accurate delay is 16383 (with delayMicroseconds)
[14:08] <costyn> This function works very accurately in the range 3 microseconds and up
[14:08] <fsphil> I hacked fldigi a while back to plot the demodulated waveform
[14:08] <costyn> so if you stay between those values, you should be ok
[14:10] <fsphil> that's better than I expected
[14:10] <costyn> hmph
[14:11] <costyn> just see I still have a delayMicroseconds(19500); // 10000 = 100 BAUD ; 20150 = 50
[14:11] <costyn> in my code
[14:11] <costyn> FAIL
[14:13] <fsphil> 51.28 baud :)
[14:14] <costyn> yea I have no idea how that ended up there.
[14:14] <costyn> dlfldigi decodes it ok
[14:14] <costyn> says more about fldigi than my code :)
[14:14] <fsphil> yea. I think my second flight was more like 280 baud than 300
[14:14] <fsphil> still works
[14:14] <fsphil> well, apart from the antenna failing and it landing in the dales
[14:15] <Hix> have you got a launch this weekend fsphil?
[14:15] <fsphil> sadly not Hix, it'll be sometime next month

[14:16] <Hix> oh, you've got launches that have stayed on teh mainland?
[14:16] <fsphil> actually three, storm travelled down the irish sea towards cornwall

[14:16] <fsphil> my success rate is 50%...
[14:16] <Hix> would never have pictured that flightpath
[14:17] <Hix> not bad for your location tbh
[14:17] <fsphil> yep. just have to be careful with the predictions
[14:17] <Hix> i can imagine
[14:18] <Hix> there's a wee bit of water around you
[14:18] <fsphil> the next will be heading towards GB too
[14:18] <Hix> are you aiming to float that one?
[14:18] <fsphil> yea
[14:18] <Hix> thought i saw something like that on here
[14:18] <Hix> into EU?
[14:19] <fsphil> possibly not that far. I'm considering putting a cut-down on it and a geofence to stop it going further than england

[14:51] <Lunar_LanderU> the issue had been that I haven't used a level shifter last year to bring the data lines from 5 to 3.3 V
[14:52] <Lunar_LanderU> would you think that you can wire an SD card directly to the SPI pins of a 3.3V AVR?
[14:52] <UpuWork> Never used one

[15:13] <cjdavies> well yes, but if I leave the receiver in exactly the same place, sometimes it will display DGPS within 30 seconds, other times it doesn't get it at all in 30 minutes
[15:13] <Laurenceb> yeah, sound slike you have poor signal
[15:13] <cjdavies> I can literally get DGPS once, then cycle the power to the receiver & it won't get it at all
[15:13] <Laurenceb> hmm
[15:13] <cjdavies> if it is due to poor signal, should the strength of the signal really fluctuate that much over such short time?
[15:14] <Laurenceb> theres probably some hysteresis
[15:14] <cjdavies> even if I cold-start each time, with no backup battery?
[15:15] <Laurenceb> yeah
[15:15] <Laurenceb> nothing that odd in the behaviour
[15:15] <Laurenceb> you need a better signal
[15:15] <Laurenceb> are you inside?
[15:20] <cjdavies> no, I wouldn't even get a 2D fix if I was inside
[15:20] <cjdavies> http://imgur.com/Pa3AVh4
[15:20] <cjdavies> I got DGPS after about 20 minutes in that location, then as soon as I moved 10ft it disappeared
[15:20] <cjdavies> 10ft in the direction you see, into an even clearer view of the sky
[15:20] <Hix> good choice on the laptop - they're excellent aren't they
[15:21] <cjdavies> it was that or a netbook, no brainer ;)
[15:22] <staylo> I just picked one of those up, they're amazing value. Refurb for 100GBP.
[15:22] <Hix> yup - bought an x201 few months back for 260 with 14 months warranty on it. before had x60s for 3 years
[15:22] <staylo> ultradocks are pennies too
[15:22] <Hix> they're pretty much bomb proof with an SSd too
[15:23] <cjdavies> I considered replacing the disk with a SSD, but I use it so infrequently I never got round to it

[19:22] <Upu> no idea if it will work

[19:27] <RocketBoy> The Aerogel looks sorta too dense to be real aerogel - but I'd be interested on how you get on with it
[19:28] <RocketBoy> we could do with a good insulator solution for picos
[19:30] <nigelvh> Sounds like aerogel to me. Wonder if they're just selling scraps so it's cheaper.
[19:32] <RocketBoy> Anyone know how to get google my_location to take an external GPS feed?
[19:32] <mattbrejza> well if you had a tablet, but that probably isnt a useful answer
[19:33] <RocketBoy> thats not a useful answer :-)

[19:35] <RocketBoy> most of the embedd GPSes I'v seen have been crap in comparison with a proper garmin etc.
[19:36] <mfa298> it used to be possible to use a GPS device with google earth
[19:36] <mattbrejza> they are good at getting signal, but thats because they cheat and use wifi
[19:38] <zyp> my phone has the fastest gps lock time of anything that I've used, since it fetches ephemeris online and use cells and wlans for pre-positioning
[19:38] <mattbrejza> i suppose there might be a plugin for chorme to use a usb gps
[19:38] <zyp> which is pretty neat for the role a phone-gps has
[19:39] <mfa298> hmmm, google maps totally fails with my location, looks like it's using location data based on my IPv6 tunnel!

[19:40] <mfa298> I shall have to wait a bit longer to sort them selves out - I submitted a form a while ago telling them it's wrong.
[19:41] <mfa298> Best one I've seen is when I had my phone acting as a portable hotspot when on holiday, Phone had the right location data (cell/gps) but the devices using it's hotspot thought they were at my home location.

[20:49] <fsphil> needs more trackers daveake
[20:50] <daveake> 1 per gopro :p
[20:50] <daveake> might not run the 3rd. Not sure yet
[20:50] <Upu> mine is very testy
[20:50] <daveake> indeed
[20:51] <daveake> and I want a backup
[20:51] <daveake> that works
[20:51] <daveake> :)
[20:51] <daveake> #2 is an NTX2 so should be ok
[20:52] <fsphil> I need some kind of splitter so I can track multiple payloads
[20:52] <Upu> don't get much chance to test code so its testing about 6 things in code and seeing how the stub antenna works

[20:54] <fsphil> or I could try the rtl-sdr with this
[20:54] <fsphil> capture all three in one go
[20:56] <Upu> I should split the Yagi actually
[20:56] <fsphil> I suppose a split after the pre-amp might work
[20:57] <Upu> can you just split it or do you need to do something ?
[20:57] <Lunar_Lander> btw I got my yaesu back home

[20:57] <Lunar_Lander> as fsphil said that I should be on station for tracking tomorrow
[20:57] <fsphil> I'd imagine you'd need something to make sure the impedance is ok
[20:57] <daveake> yup
[20:58] Action: fsphil is always on standby for tracking :)
[20:59] <daveake> I might track from the car tomorrow :)
[20:59] <daveake> We'll be on the road for a few hours
[20:59] <fsphil> we need a running commentary

[21:01] <Upu> that looks easy..ish fsphil
[21:01] <fsphil> The Stirk Array
[21:01] <Upu> lol
[21:01] <fsphil> just needs a box the right size
[21:01] <fsphil> and some wire
[21:01] <Upu> that looks like 1 radio to 2 antennas
[21:02] <fsphil> it works both ways I think
[21:11] <Upu> I think I might have a go at making one

[23:19] <fsphil> unless one of the boffins sets up the aprs bridge thingy
[23:20] <kc5trb> Payload will run 300 milliwatts standard aprs on 144.39 MHz. call will be KB9KHO-1 With a 1 minute toggle schedule. every minute will have location, and every other minute will have telemetry added to the location string. Telemetry will be status of the valve as well as temps in and out, volts of batterys as well as the solar panel. This payload can in theroy run forever as long as it gets sunshine.

[23:44] <NSS-52> homebrew system, with one of the radiometrix transmitters.
[23:44] <nigelvh> Using the trackuino code?
[23:45] <NSS-52> Honestly I really do not know. A fellow of the group bult it I offered the ride.
[23:45] <nigelvh> As good an answer as any.
[23:45] <NSS-52> Sorry, maybe the builder will show up soon.
[23:46] <nigelvh> No problem. The only thing I'd recommend is shortening your path. From high up you'll get into a lot of recievers and you've got a fairly wide path.
[23:47] <KT5TK_QRL> He may change the path on the fly
[23:47] <nigelvh> Entirely plausible
[23:47] <KT5TK_QRL> The telemetry packet is a bit unusual though
[23:47] johnboiles (Adium@bastion.sfo1.yelpcorp.com) left #highaltitude.
[23:47] <nigelvh> Yes, I would have thrown it into the comment field of the position packet, but it doesn't matter all too much.
[23:47] <KT5TK_QRL> It won't be displayed in graphs on aprs.fi
[23:48] <NSS-52> true.
[23:49] <nigelvh> Anyway, good luck. I'm looking forward to following your flight.
[23:49] <KT5TK_QRL> It's not a position packet (that would have a :$)
[23:49] <nigelvh> Depends on the packet.
[23:50] <KT5TK_QRL> Hes sends out raw $GPGGA statements
[23:50] <KT5TK_QRL> which is possible in the APRS standard
[23:50] <nigelvh> Yes, I would have made it a non-timestamped position packet and thrown telemetry into the comment field.
