[00:04] <Oddstr13> Dr_Dan: For that project, I'd use an Arduino instead of RPi
[00:04] <Oddstr13> Arduino with GPS and SD card
[00:05] <Dr_Dan> Can you suggest (send url) to a good quality GPS Shield?
[00:06] <Oddstr13> http://www.instructables.com/id/Arduino-GPS-Datalogger/
[00:06] <Dr_Dan> Ty
[00:06] <Oddstr13> Well, any GPS receiver that outputs serial NMEA data would work
[00:07] <Oddstr13> but, I have the shield from sparkfun lying around here somewhere, I've used that one while wardriving before :)

[00:11] <Dr_Dan> I found a shield from AdaFruit that has SD card, GPS, clock battery. Have you seen it http://www.adafruit.com/products/1272
[00:15] <Oddstr13> Dr_Dan: havn't seen that one before, no, but if i needed a gps logger now, i'd take that one, as it includes the GPS and µSD on the same board
[00:15] <Oddstr13> also, optional external antenna is nice

[00:16] <Dr_Dan> And RTC with clock battery
[00:16] <Oddstr13> RTC isn't that big a concern for me, as you get the time from the GPS anyway
[00:17] <Oddstr13> but, i guess it could be nice if you against all odds are compleetly out of gps coverage
[00:18] <Oddstr13> also, if you're buying an arduino, I would recommend the Uno over the Leonardo
[00:19] <Dr_Dan> I like the little breadboarding area so if you're experimenting with I/O theres a place for that
[00:19] <Oddstr13> I find the Leonardo annoying to work with, due to the resetting serial port
[00:19] <Oddstr13> indeed
[00:20] <Oddstr13> could easily fit stuff like humidity sensor, barometer and temperature on that prototyping area
[00:21] <Dr_Dan> I guess it uses the Adafruit GPS Library for arduinos
[00:22] rwsq1 (~rwsq1@234.11-35-82.static.virginmediabusiness.co.uk) joined #highaltitude.
[00:24] <Oddstr13> just a normal software serial connection
[00:29] <Dr_Dan> NMEA output i see.
[00:33] <craag> For GPS boards for both pi and arduino: http://ava.upuaut.net/store/index.php?route=product/category&path=59_60
[00:35] <craag> Extreme precision timing with gps is easy using the PPS output
[00:36] <craag> 2m positional accuracy might be a bit harder to guarantee
[00:37] <Oddstr13> can't really guarantee that for GPS at all
[00:37] <Oddstr13> unless you're the U.S. millitary or allies
[00:38] <craag> nope, using ublox M8 with gps+glonass and a well-placed active antenna will get you closest you can I think.
[00:38] <Dr_Dan> Lol. Craag did you see my link above to Adafruit's new board with SD and GPS
[00:39] <Dr_Dan> It has a clock battery backup. Im assiming it keeps time when the system is not receiving gps updates
[00:39] <craag> Most of hab supplies gps breakouts have slots for the battery backup too
[00:40] <craag> It allows the gps to remember some of the gps satellite information as well as keeping time, and so gets a repeat lock a lot faster
[00:40] <craag> and more accurately in some cases

[03:48] <Ian_> Check the wiki in the first instance. UK members start showing up here around 0730z
[03:51] <hamiltron> thanks Ian_
[03:52] <hamiltron> i'm in NYC
[03:53] <Ian_> Welcome to the channel. Check out the wiki as there is a lot there. the philosophy seems to be that there is little off the shelf ready to go packages, but plenty of
[03:54] <Ian_> kit and rarer RF components from the likes of habsupplies. There is a lot of example code but the recommendation seems to be to cobble together some of it and.
[03:55] <Ian_> get it working properly, then throw it away and write your own from scratch. I have watched more than a couple of youths programming out loud (painful experience)
[03:56] <Ian_> as they struggle through some of the concepts, but notice how much they grow in just a few weeks as their questions are answered to get them over the programming speed bumps.
[03:57] <Ian_> A lot of newhabs start out with Arduino boards and migrate to the naked Atmega328p chips. Ublox 7 and more recently 8 series GPS are good to go
[03:58] <Ian_> Try not to mention Spot GPS devices or hand warmers as they will both get you laughed into a ditch somewhere. Pi boards have been used more recently but are seen to be power hungry beasts
[04:00] <Ian_> b-64 aka M0XER-4 on APRS launched from Silverstone UK on July 12 is currently on lap 9 of the northern hemisphere
[04:00] <Ian_> !whereis b-64
[04:00] <SpacenearUS> 03Ian_: 03B-64 was over 03South, Iceland 10(64.1198,-19.0706) at 0312451 meters about 03a day ago
[04:02] <Ian_> There you go hamiltron, Zeusbot knows all. I'm off to my bed as it's 4am here at the moment. Good hunting and buy in an Arduino Uno or two and a slack handful of 28pin Atmega328p-pu chips to keep you busy with projects.

[04:10] <Ian_> Around UK and Europe you will see from http://habitat.habhub.org/mobile-tracker/ that there has grown up in the last three or four years a community ground station receiver network.
[04:11] <Ian_> With the advent of the B-1 through B-66 flights in the last eighteen months or so, APRS has been used for that extended reach that 434MHz ISM band doesn't quite have.
[04:13] <Ian_> Now of course the AETH28-x Google Loon balloons are being tracked via APRS too. The map makes it look like B-64 is a demented slug with it's trail of success and the Loon balloons look like waves from invasion of the body snatchers.

[10:24] <MaXimaN> I am using 380
[10:25] <MaXimaN> Self-heating of the radio doesn't seem too bad, the signal is nice and stable from about one second in
[10:26] <zjztgj> short question in between: is APRS for balloons only on 2m band or on 70m as well?
[10:26] <zjztgj> *cm
[10:26] <MaXimaN> zjztgj: APRS is predominantly on 2m
[10:26] <MaXimaN> There are 70cm frequencies but used a lot less.
[10:27] <MaXimaN> I wish the websdr software had a waterfall instead of a waterfly
[10:27] <zjztgj> is there an advantage of 70cm for balloons?
[10:28] <zjztgj> antennas are quite big, essential if directional
[10:28] <craag> MaXimaN: We had a go at modifying the code to do that - but it didn't work too well unfortunately.
[10:28] <amell> still not decoding. seems worse if anything
[10:28] <zjztgj> i meand 2m

[10:29] <craag> You don't want directional antennas on the balloon
[10:29] <craag> And 70cm is the best radio band permissible in the UK - hence why we use it.
[10:29] <edmoore> yeah i use an isotropic antenna
[10:29] <craag> heh
[10:29] <SpeedEvil> sort-of-on-topic http://piximus.net/media/13779/scared-of-heights-44.jpg
[10:29] <SpeedEvil> I use an isotonic antenna.
[10:30] <SpeedEvil> Hydration is important.
[10:30] <MaXimaN> zjztgj: It's also about coverage. In western europe we have 70cm balloon tracking well-covered most of the time, unless it wanders too far south
[10:31] <MaXimaN> zjztgj: And as craag says, we can't broadcast on 2m from the air in the UK, so APRS is no-good for us
[10:32] <zjztgj> sure, but for a very light balloon a 2mm unidirectinal antenna is big as well
[10:32] <zjztgj> sry 2m

[10:33] <SpeedEvil> zjztgj: It's +-0.5mish on the string above and below the payload
[10:33] <MaXimaN> zjztgj: Not by default. We use a custom version of fldigi to decode and upload to habitat and spacenear.us
[10:34] <MaXimaN> For APRS it is uploaded by a script taking data from aprs.fi

[10:34] <craag> The 10mW power limit on 70cm ISM makes the link budget for afsk a little tricky at times
[10:35] <MaXimaN> Still no greens for me on EDUPIC
[10:35] <craag> so use RS232 FSK, aka RTTY

[11:46] <zjztgj> what is the reason that the 868 MHz band not commom for balloon tracking? it allows up to 20dbm
[11:46] talsit_roam (uid30008@gateway/web/irccloud.com/x-nptveasngzppeswn) left irc: Quit: Connection closed for inactivity
[11:47] <craag> We have used 868MHz, however until recently it has been difficult to get SSB receivers for that band
[11:47] <LazyLeopard> zjztgj: Listeners (or rather, lack of them).
[11:47] <craag> 70cm ISM band has the nice touch that it's covered by a lot of Ham Radio rigs, meaning lots of people already have the kit to listen and help track
[11:47] RA9SOA (5c3181bd@gateway/web/freenode/ip. joined #highaltitude.
[11:49] <zjztgj> makes sense, but with cheap sdrs that will change?
[11:50] <craag> The number of potential listeners will still always be less then 70cm
[11:50] RA9SOA (5c3181bd@gateway/web/freenode/ip. left irc: Client Quit
[11:50] <craag> And you can only use 20dBm with 10% DC limit
[11:51] <zjztgj> so its more equal to 25mw, but still
[11:51] <Geoff-G8DHE-m> Also would need to put up new aerials on 868Mhz
[11:51] <craag> zjztgj: how did you work that out?
[11:53] <zjztgj> sry. i ment 50mW avaradge
[11:53] <craag> 20dBm = 100mW
[11:54] <zjztgj> omg
[11:54] <zjztgj> 500 mW seams to be allowd
[11:54] <zjztgj> so equal to 27 dbm
[11:55] <craag> Ah yes it is, my bad. I've only ever used 100mW transmitters on it.
[11:55] <zjztgj> my 20 dbm figure was wrong
[11:55] <zjztgj> i sad 20 dbm some line above...
[11:56] <craag> Yeah, I got confused. So yes people have used it - but stuff like transmitter drift is twice as problematic as at 434 of course.
[11:56] <craag> You also have the additional path loss.

[11:57] <mattbrejza> 6dB more PL and 10dB less due to 10% DC
[11:57] <mattbrejza> so you gain 1dB
[11:57] <mattbrejza> yay
[11:58] <mattbrejza> (assuming were talking maximising bandwidth
[11:58] <craag> There's been a couple of flights using the new Lora mode on 868 as it allows wider bandwidth.
[11:58] <gonzo_> path loss is a confusing concept. I prefer to think of space as lossless and use capture area of antennas
[11:58] <craag> But that's more due to limitations in the module rather than the tiny gain in link budget.
[11:59] <mattbrejza> gonzo_: true
[12:00] <gonzo_> On balance I assume that if you half the wavelength you use an ant that is twice as big, relativly, so the capture area prob stays tha same
[12:01] <zjztgj> so overall the advantages compared to 70 cm are quite limited. No driving potential to go fore 868 MHz..
[12:01] <gonzo_> as people usually use the biggest anty they can
[12:02] <gonzo_> I would say that 434 had the great advantage of an existing user base and commercial kit available
[12:02] <craag> zjztgj: Nothing to stop people playing around with it, but yes that's why most tend to stick with 434.
[12:02] <daveake> Only advantage I can see is the 300kHz-wide 100% DC section but that's only 5mW erp
[12:02] <gonzo_> agreed. I have an ant/lna for 868
[12:02] <mattbrejza> we're not really pushing hte limits of 434 atm ayway
[12:02] <gonzo_> waiting for an excuse to try it
[12:03] <daveake> As has been pointed out :p you can still use wide-ish bandwidths on 70cm albeit at 10% DC
[12:03] <gonzo_> btw, did the idea for a 434LPD aprs network go anywhere?
[12:03] edmoore (~ed@ left irc: Quit: Leaving
[12:03] <daveake> Also, if you want to do an uplink, 70cm is the best bet as you can use plenty of power on the ground
[12:05] <zjztgj> daveake: but the wider band inreases the probability of beeing occupied as well..
[12:06] <daveake> it does
[12:08] <daveake> lora does have some cleverness though - the same data gets spread across the bandwidth so it has a chance of getting through anyway
[12:08] <daveake> also with multiple receivers it would be bad luck if everyone was affected by interference
[12:09] <mattbrejza> when it works ¬.¬

[16:38] <lz1dev> don't tell them, they'll come steal your gps module :(
[16:38] <Upu> haha
[16:39] <MikkMihkel> :D
[16:39] <Myself> yeah, broadcasting your position just invites people to get into their airplanes and go snatch it out of the air!
[16:39] <MikkMihkel> Yeah :D

[16:39] <MikkMihkel> Estonia/Latvia border
[16:39] <Upu> ah ok
[16:40] <Upu> well you will get coverage into Poland I suspect
[16:40] <mfa298> In general APRS has a wide receiver network but needs a suitable radio license (amateur radio) and cant be used in all countries when airborne. There's a license free 434 MHz band (which is what we use in the UK) for which there's a good listener network throught parts of Europe. This band can generally be used airborne (although you should check local laws)
[16:40] <Upu> APRS isn't permitted airborne in Latvia
[16:40] <Upu> No information on Estonia
[16:41] <Upu> I would use 70cms
[16:41] <Upu> you mailed me about the Pi In The Sky board

[19:55] <craag> You mean for video on the ascent?
[19:56] <craag> Most people use a long cord between payload and balloon (>10m), which reduces noticable swing.
[19:56] <Harvy> Yeah mainly for video.
[19:56] <craag> You can also add gyros to really reduce it
[19:56] <Harvy> We had a 10m line from ballon to parachute and 5m from parachute to payload.
[19:57] <jededu> I think EDUPIC9 is going in I need to get higher
[19:57] <craag> A free-rotation joint in the line like you get on fishing kit can cut down on sharp spinning
[19:57] <SA6BSS> jededu: then you need a custom envelope
[19:58] <Upu> I'm having to manually fix each one of these
[19:58] <jededu> I know :)
[19:58] <jededu> Why upu
[19:58] <Harvy> craag, Yeah were thinking that or I've seen in some videos long rods attached to the bottom of the payload.

[20:04] <Harvy> craag, Wow ok that's a bit more crazy. So I'm guessing v2 reacts to the movement?
[20:04] <craag> I did see a video of an old CUSF flight with *massive* pieces of cloth or something hanging down to stabilise it - dunno how well it worked though and not something I'd like to fly :/
[20:05] <Harvy> craag, how about these wooden rods that people use. It seems to move the weight away from the payload. Shoudl that work?
[20:05] <craag> v2 I think will point in a programmed direction, and adjust to any spin, roll or pitch, holding the camera in the same direction.
[20:06] <craag> err people tend to use those to hold something out in front of the camera, not sure they had much stability benefit.
[20:07] <craag> I haven't done much photography yet though - so probably not the best person to speak to.

[21:11] <Lunar_Lander> I imagined
[21:11] <mikestir> it'd be pretty bad if it didn't do that
[21:11] <Lunar_Lander> yea
[21:11] <Lunar_Lander> I kept selecting the track width all the time without thinking too much about it
[21:12] <mikestir> I think they've got stuff like matched length buses and diff pair routing in the latest version of kicad now though

[21:13] <Lunar_Lander> sounds good
[21:13] Action: Myself teaches a coworker about common-mode noise rejection and the folly of driving a differential input with a single-ended signal and one leg grounded. Heh, heh.
[21:13] <Myself> (If that turns out to be the root cause, I'm gonna laugh really, really hard.)
[21:13] <Lunar_Lander> does the bus length matching have to do with latency?
[21:13] <mikestir> yes
[21:13] <Lunar_Lander> ah
[21:13] <Lunar_Lander> :)
[21:13] <mikestir> it's important on DDR interfaces
[21:14] <mikestir> that's why you'll see all those wiggly tracks on a pc motherboard or dimm
[21:14] <Lunar_Lander> yea
[21:15] <Lunar_Lander> mikestir, the tube electronics you posted
[21:15] <Lunar_Lander> nice :)
[21:15] <mikestir> yeah that was just a little joke
[21:15] <Lunar_Lander> I actually saw radiosonde payload papers from the 30s-60s which had those all over the place
[21:15] <Lunar_Lander> and weighed 6-10 kg
[21:16] <pc1pcl> might be more resistant to radiation though..

[21:26] <Lunar_Lander> thinking about getting a hot-air soldering machine at ebay
[21:26] <Lunar_Lander> read that they are OK for doing small things
[21:26] <edmoore> they're very useful for desoldering
[21:27] <Michemto> well yeah
[21:27] <edmoore> and for doing solderpaste parts without an oven
[21:27] <Michemto> I'd really like to use somekind of basic valve
[21:27] <Lunar_Lander> that sounds good
[21:27] <edmoore> i thoroughly recommend using them in conjection with a pre-heating bed
[21:27] <Michemto> which will allow to flow warmed liquid to the container
[21:27] <edmoore> especially where you have large copper planes
[21:27] <Lunar_Lander> ah ok
[21:27] <Michemto> when altitude is reached
[21:27] <Michemto> if you want to hear specific information, pm, but yeah... valve is needed :D
[21:29] <edmoore> oh a fluid valve
[21:29] <edmoore> i thought people were still talking about thermionic valves
[21:29] <edmoore> why do you want to move fluids around?
[21:30] <Michemto> well... i have to keep fluid warm and steady in container
[21:30] <Michemto> until balloon gets to stratosphere
[21:30] <Michemto> and then this fluid should change it's container
[21:30] <Michemto> kind of a experiment :)
[21:30] <Michemto> just need the valve :D
[21:31] <edmoore> well, plenty of valves are on the market for all sorts of applications
[21:31] <Michemto> or some kind of mechanism which allows me to keep something closed.. and then released (container is upside down..) so this little gravitation will help it to fall down
[21:31] <edmoore> it should just be an off-the-shelf thing
[21:31] <Michemto> Yea.. but i didn't really find anything working with low volts
[21:31] <Michemto> voltage
[21:32] <edmoore> how low is low?
[21:40] pc1pcl-p (525f6ef3@gateway/web/freenode/ip. joined #highaltitude.
[21:42] <Geoff-G8DHE> Make it out of plastic if weight is important for the valve http://www.ictmdeklerk.nl/servo-controlled-valve/
[21:43] <goopypanther> Michemto: does it need to close again later?
[21:43] <Michemto> nope
[21:43] <Michemto> dunno, voltage coming from pi
[21:43] <pc1pcl-p> if it only needs to be a one-shot, things that have been used for cut-down might work?
[21:43] <goopypanther> you could always use nichrome to burn through some plastic
[21:44] <Geoff-G8DHE> design is already available http://www.thingiverse.com/thing:20661
[21:44] <goopypanther> otherwise I'd say use a solenoid to pull out a stopper
[21:45] <Michemto> hmm... nichrome vs servovalve
[21:45] <Michemto> plastic part should be really thin in this case
[21:45] <Laurenceb_> what are you trying to do?
[21:45] <Michemto> but yeah it may be working
[21:46] <Geoff-G8DHE> or http://botbench.com/blog/2011/03/12/mindsensors-pneumatic-valve-servo-kit/
[21:46] <edmoore> i would hope you're not planning on powering a valve directly from some pi i/o
[21:46] <pc1pcl-p> wax stopper in stead of plastic?
[21:48] <pc1pcl-p> spring to store energy,cut/melt retaining line, shoot bolt into container?

[21:50] <Michemto> hehe, bolt into container :D
[21:53] <pc1pcl-p> bolt could be just a needle (maybe from a syringe?)

[21:56] <pc1pcl-p> depends on the exact fluid container etc. if container is a balloon with water probably different than if you have a thermos of hot coffee...

[22:07] <Michemto> :D I think i got a perfect idea... will cover neck with wax stopper and will melt nichrome inside, once power is applied, wax will melt and liquid will flow :)
[22:07] <Michemto> thanks :)
[22:07] <Lunar_Lander> yay
