[00:00] <cambazz> where are you in england btw
[00:00] <craag> southampton
[00:01] <cambazz> :) i just love trains of england
[00:01] <craag> We got a batch from the US a few months ago, didn't see any from china on there at the time.
[00:02] <craag> hehe, I'm not much of a train fan myself. I know a fair few people that are though!

[05:53] <Maxell> LeoBodnar: you are flying with the WIDE2-2 path right? Might be intresting to try WIDE1-1,WIDE2-1
[05:53] <Maxell> That would allow for small/indoor/temporary digis to digipeat the balloon.
[05:53] <LeoBodnar> WIDE2-1 only
[05:54] <Maxell> How so?
[05:54] <LeoBodnar> anything wider/deeper is sneered upon
[05:54] <Maxell> Oh, WIDE2-1 would digipeat once.
[05:54] <LeoBodnar> yeah
[05:55] <Maxell> Why not WIDE1-1? :)
[05:55] <Maxell> That would also digipeat.
[05:55] <Maxell> Once.
[05:55] <LeoBodnar> beacuse you miss all the WIDE2 ones
[05:55] <LeoBodnar> which are good ones on top of mountains
[05:55] <Maxell> WIDE2-2 repeaters also repeat WIDE1-1 iirc.
[05:55] <LeoBodnar> really?
[05:55] <Maxell> Let me check here in The Hague.
[05:56] <Maxell> This is me shooting a WIDE1-1,WIDE2-1. Digipeated and then igated: PI1RWK,WIDE1*,WIDE2-1,qAR,PD2ATG-2
[05:56] <Maxell> PI1RWK is high up.
[05:57] <Maxell> And still gets igated: WIDE1-1,WIDE2-1,qAR,PD0HNI-10
[05:57] <LeoBodnar> I thought separation between WIDE2 and WIDE1 is quite explicit
[05:57] <Maxell> Another direct igate: WIDE1-1,WIDE2-1,qAR,PA3EKI-10
[05:57] <Maxell> And delft repeater direct igateing (also huge repeater) WIDE1-1,WIDE2-1,qAR,PI1DFT
[05:58] <LeoBodnar> oh well, of course igates will catch direct ones
[05:58] <Maxell> LeoBodnar: well, we have some smaller WIDE1-1 repeaters in the Hague, for portable use.
[05:58] DL7AD (~quassel@193.175.213.20) joined #highaltitude.
[05:58] <Maxell> They only repeat WIDE1-1.
[05:58] <LeoBodnar> WIDE1-1 is usually co-located with igate anyway?
[05:58] <Maxell> Yeah, run from home setup
[05:59] <Maxell> Or in a moving car.
[05:59] <LeoBodnar> it's to get around really local geography, is this right?
[05:59] <LeoBodnar> like a black spot behind a supermarket, etc
[06:00] <Maxell> Yep. PE4CE here runs a WIDE1-1 digipeater and igate for portable 2 meter in the city.
[06:00] <Maxell> Since portable antennas suck
[06:00] <Maxell> However, he has a good view to digipeat towards PI1DFT
[06:01] <Maxell> PE4CE*,WIDE2-1,qAR,PI1DFT hmm
[06:01] <Maxell> And yes, that is a valid .nl callsign :)
[06:02] <LeoBodnar> hehe
[06:02] <Maxell> And I might consider running aprs-is to rf for the sake of moar RF :)
[06:03] <LeoBodnar> XD

[06:03] <Maxell> hey - we have a uhf aprs freq mostly just announcing PI1RWK and the PD2ATG igate ....
[06:04] <Maxell> LeoBodnar: that would be nice
[06:05] <LeoBodnar> i am very curious
[06:05] <Maxell> Still have to figure out how to set some filters in xastir since I do not want to internet->rf all of the aprs-is

[06:06] <LeoBodnar> haha

[06:09] <Maxell> Here too.
[06:09] <Maxell> On a car. Without SmartBeaconing.
[06:10] <Maxell> Quite dangarous to send your car's position with such large path.
[06:10] <Maxell> iirc the PI1DFT has a sane filter that limits it to WIDE3-2 as soon as it digipeated.

[06:56] <Guest61455> Hi, looking for some help getting a school HAB project up and running. We want to launch a raspberry pi based project from our school in mid July, We have some programming experience and some limited electronic experience. Is Mid July too optimistic?

[12:20] <aadamson> Upu, UpuWork - I've done some work on your geofence code if you want it back. I used a ray tracing alorithm to determine the point in a polygon and because everything should be x,y (lon,lat) I changed the order of the const arrays... still have a little more work to do, but I can give it back to you if interested.?
[12:20] <aadamson> Also I added the US, CA, and AK areas that you had kml files for
[12:22] <Upu> stick it on github somewhere so its availble for all
[12:22] GW8RAK (~chatzilla@87.112.154.62) left irc: Ping timeout: 240 seconds
[12:23] <aadamson> ok, will do and will let you know. the check logic became really small once you do the above - e.g here is the ray trace pnp - http://bcas.tv/paste/results/ph8i7g47.html
[12:24] GW8RAK (~chatzilla@87.112.154.62) joined #highaltitude.
[12:24] <aadamson> it's a pretty standard function do to exactly what you were doing, it also doesn't need the closing point because it can look back (or forward which ever you prefer) to find the closing point as its the same as the starting one. :)

[12:29] GW8RAK (~chatzilla@87.112.154.62) left irc: Ping timeout: 264 seconds
[12:29] <fsphil> it was based on this code iirc: http://ukhas.org.uk/code:uk_polygon
[12:30] <fsphil> which is essentially the same as what you linked above, just on more lines
[12:30] <aadamson> Ah, the one I started from wasn't

[12:31] marshall_law (~marshall_@97-93-250-127.dhcp.ftwo.tx.charter.com) left irc: Remote host closed the connection
[12:33] <aadamson> actually it was similar to what you linked, but slightly different and while things were labeled x/y, it was lat/lon which is actually y/x so I juggled things around to be x/y and I used a smaller pnp routine
[12:34] <aadamson> but code I started from had code for the nth element being the same as the 0th which wasn't needed and made the array 3 int32_t's smaller each

[15:55] <NickB_> good to know
[15:56] <Upu_M0UPU> I'll be back in 30
[15:57] <WB8ELK> Here's the answer from the BalloonTime folks who make the tank I used: Medical helium is over 99% pure. Balloon grade helium is approximately 94% - 96% pure. Our helium has been tested to be at least 98% pure, with most readings over 99% pure.
[15:57] <WB8ELK> so that is pretty good quality.
[15:58] <NickB_> ah thanks for the info
[15:59] <NickB_> can just order them by mail

[16:14] <aadamson> sheesh, note to self, don't try to outsmart the smarts... configuring an LED pin as an analog input just to save power.... well all it does is allow the pin to float (there was no external pullup/down) and the LED thinks it's getting PWM and glows dimly... (AND USES POWER... DUH)
[16:16] <mattbrejza> sentient LED
[16:16] <aadamson> yeah exactly!

[16:19] <mattbrejza> and led cant just decide what it wants and glow because it feels like it. if one end isnt connected to anything it isnt going to light up
[16:20] <adamgreig> sounds like you probably enabled an internal pullup and that's driving the LED
[16:20] <mfa298> simple solution, attack it with soldering iron/scalpel and remove the led

[16:26] <aadamson> no, if you enable the pin as an analog input (which is the lowest power way to configure, there is nothing to stop it from floating, it it floats high, it turns on the led, if it float low it turns if off, the internal pullup/down was also disabled...
[16:26] <aadamson> The the pin was oscillation and hence the LED was dimly lit
[16:27] clopez (~tau@neutrino.es) left irc: Ping timeout: 245 seconds
[16:27] <aadamson> once did away with the define which was removing the specific configuration for the pin, and set it to low, obviously the led went dark
[16:27] GW8RAK (~chatzilla@227.204.189.80.dyn.plus.net) left irc: Remote host closed the connection
[16:28] <aadamson> it was one of those last minute, oh, let me try this, and I didn't look check it very well :)... but all fixed now.
[16:28] clopez (~tau@neutrino.es) joined #highaltitude.
[16:29] <adamgreig> aadamson: that sounds... unlikely
[16:29] <adamgreig> did you actually put a scope probe on the pin output? with and without the LED there?
[16:30] <adamgreig> (what microcontroller is this?)
[16:31] <mfa298> if it's acting as a current source when set as an input that sounds somewhat like a broken design.
[16:35] <aadamson> ah, found the issue, it wasn't configured as input because it's shared with one of the jtag pins and the configasanalog skipped when when they were active... but the internal pull/up down was not enabled in this one specific configuration and was allowing the pin to float
[16:35] <aadamson> I configure everything as an input as the first thing, then those that get used later override that.
[16:35] <adamgreig> are you still sure? the JTAG pins have pull up resistors enabled by default until you turn them off
[16:37] <aadamson> I can only tell you what I see... it's a 0603 green led with a 330ohm resistor between it and the pin, and the LED is to ground on the other side and when I didn't specificially init the pin, the led was dimly lit
[16:37] <aadamson> when I do it isn't... and yes I look at it on a scope and it was floating
[16:37] <mattbrejza> your scope has float detect?
[16:37] <aadamson> I'm not sure that's true on the jtag pins on the L1, but I'm not 100% sure
[16:38] <aadamson> mattbrejza, my scope can watch the pin oscillate high and low when it was doing that
[16:39] <mattbrejza> right...
[16:39] <aadamson> why it was moving high and low, I'm not 100% sure of yet.
[16:40] <aadamson> but that's kinda low on the priority list at the moment. the *design* problem and yes there is one

[16:40] mikestir-work (~mike@62.8.120.10) left irc: Ping timeout: 252 seconds
[16:41] <adamgreig> aadamson: all STM32s have built in pull up and pull down (as appropriate) pins on the JTAG pins, which are enabled by default
[16:41] <aadamson> is that finding led's that work at 2.0v correctly is kinda hard and so I'm using one that should be biased with higher voltage so it could be related to that... as well... They work and really are only for debugging
[16:41] <aadamson> adamgreig, good to know... I don't usually use them dual purpose but did in this one case as I'm only using SWO and trace
[16:41] <adamgreig> so it really sounds like your jtag pin had the default pullup resistor left enabled, which was supplying Vcc to your LED through some large resistance
[16:42] <adamgreig> hence the dim glow
[16:42] <adamgreig> you wouldn't expect an actually floating pin to ever drive an LED high or low, since it's not connected to a current supply
[16:42] <aadamson> yep, could very well be adamgreig and I never saw it because normally I had the pin configured, but last night made a change and removed that

[16:42] <adamgreig> unless you have mad noise pickup. then you have other problems
[16:42] <aadamson> adamgreig, yeah, that what was the puzzling part, I knew it was *well, I thought I did* configured as analog - which as it turns out it wasn't
[16:42] <mattbrejza> well i dont see any other sensible suggestion as to why an LED would be dimly on
[16:43] <adamgreig> a pullup seems the first obvious culprit really
[16:43] <aadamson> I need to check too some of the jtag pins have IRQ's enabled on them
[16:44] <aadamson> and this may be one of those... had that problem on an F1 design where when I wasn't using jtag, the usb wouldn't init, because of a run away irq :)
[16:44] <aadamson> had to disable the extra jtag functions to make usb work reliably

[18:53] <craag> chrisstubbs: 3x AAA, should last a while surely?
[18:53] <chrisstubbs> it may still be alive
[18:53] <chrisstubbs> Let me grab another board and see what the current draw is
[18:54] <craag> That's 2Ah, even at 100mA that's 20 hours
[18:54] <craag> If you're using power-saving on the gps - will be a lot less
[18:55] <amell> I have to go collect the caravan, so could combine that with trying to claim a free hab.
[18:55] <craag> amell: Might as well give it a go
[18:55] <amell> if it will be alive at 9am tomorrow morning, its worth a shot
[18:55] <craag> Might even be somewhere obviously visible
[18:56] <malgar> b52 is crossing a lot of cities :)
[18:56] <amell> is the snus prediction reasonably accurate?
[18:56] <craag> amell: It assumes local ground level is 0m ASL
[18:56] <amell> b52 is about to bomb istanbul
[18:57] <craag> amell: Account for that, and it tends to be very accurate
[18:57] <amell> so do you think its short or long on the track?
[18:57] <craag> Should be short, one mo
[18:57] <amell> this area is the fens, it is practically sea level
[18:58] <LZ1NY_> Now B-52's frequency is 3.5 kHz
[18:58] <LZ1NY_> lower
[18:59] <craag> amell: Elevation of 2m :P
[18:59] <craag> So prediction should be spot on
[18:59] <LZ1NY_> I am still monitoring on waterfall but last decodes failed
[18:59] <craag> amell: Perhaps slightly to the east if you extrapolate the curve of the last 2 data points
[19:00] <amell> chrisstubbs: can you describe cheapo, white polystyrene? any chute attached?
[19:00] <craag> Oh nice open field :D
[19:00] <amell> depends if the field is full of rape seed&
[19:00] <craag> mm true
[19:00] <chrisstubbs> ~60ma so yeah about 20 hours from 1.2ah
[19:01] <chrisstubbs> you may be in luck :)
[19:01] <amell> what was the freq and decode again?
[19:01] <chrisstubbs> just below 434.300 7n2 rtty 450hz shift
[19:02] <amell> well if the field is full of rape, I will listen for it, if nothing heard i will just scoot off.
[19:02] <LeoBodnar> it's below -50C LZ1NY_ so frequency drifts
[19:03] <LZ1NY_> Amasing to hear it from 300 km :-)
[19:03] <LeoBodnar> hehe
[19:04] <chrisstubbs> amell, it will look something like https://farm6.staticflickr.com/5520/9575572979_7d206977ff_b.jpg, possibly with different colour tape. No chute and very little balloon still attached I expect
[19:07] <amell> ok. I will look for a fat spider
[19:07] <amell> and can someone Upu? not delete cheapo off snus until at least 11am tomorow?
[19:07] <LZ1NY_> May be it is time to say "Good bye, B-52 and have a nice flight!" from Sofia, Bulgaria :-)

[19:45] <chrisstubbs> are you connected at the right speed? should say 9600 in the corner of serial monitor

[19:55] <Silver_IV7> i can send data with the transmitter and the gps works perfectly in 4,5 it's just 0,1
[19:55] <Silver_IV7> the only thing i can think is when the gps is in 4,5 it runs a 4800 baud so maybe it's stuck at that and won't change to 9600?

[20:11] <mikestir> aadamson: LeoBodnar: Upu: have any of you used the xtal oscillator in the 4060 or have you only used it with an external clock?
[20:11] <Upu> only external for me
[20:12] <mikestir> it seems to be oscillating very low, like it has loads of stray capacitance even with XO_TUNE set to 0
[20:12] <LeoBodnar> i had XO on Rev.A
[20:12] <LeoBodnar> corrected against GPS clock
[20:12] SP9UOB-Tom (~verox@matrix.verox.pl) left irc: Quit: night
[20:13] <aadamson> only external for me
[20:13] <mikestir> LeoBodnar: how much pin capacitance did you reckon there was? did you spend any time tuning it to that extent?
[20:14] <LeoBodnar> 2-3pF
[20:14] <mikestir> hmm maybe need to take the load caps down a bit further then
[20:14] <LeoBodnar> load caps?
[20:14] <LeoBodnar> you use external load caps?
[20:15] <aadamson> yeah, isn't there built in caps in the si part that you can select?
[20:15] <aadamson> with a vcxo, I have to turn those off
[20:16] <mikestir> you can only add about 9pF with the tuning caps, so it needs a bit more
[20:18] <mikestir> it's about 60ppm out with XO_TUNE=0 though, so I'll need to take the loading down some more
[20:20] <LeoBodnar> not sure you need external loading
[20:20] <LeoBodnar> what is your XO load capacitance?
[20:20] <LeoBodnar> from DS
[20:22] <mikestir> crystal is 10pF
[20:22] <LeoBodnar> you don't need any external caps
[20:23] <LeoBodnar> parasitic load is 2-3pF and Si4060 can go up to 11pF internally
[20:23] <mikestir> yeah I've just done digging in the datasheet and come across the 11pF value for XO_TUNE=127
[20:23] <LeoBodnar> i have never seen Si4060 design with external loading caps
[20:23] <mikestir> ok, well that's easy to test anyway.
[20:24] OH7HJ-1 (~Juha@dsl-jnsbrasgw2-50dfa7-205.dhcp.inet.fi) joined #highaltitude.

[20:24] <LeoBodnar> yes

[21:29] <SilverIV7> "I was reading the BBC article about HABing and the issues of finding the payload afterwards. Probably been tried before but just in-case, could the payload be contained in a glider body and using automonous drone tech, on release glide back to the launch area?"

[21:32] <SpeedEvil> Unless it's a gliding parachute
[21:32] <amell> db_g6gzh: yes please. partial decodes would be useful.
[21:32] <amell> I find it I can fly it again? :)
[21:32] <SilverIV7> Is it illegal because it's unmanned and automated then?
[21:33] <SpeedEvil> Or unless it's released within unassisted visual range of the pilot
[21:33] <SpeedEvil> SilverIV7: It's illegal because it's not in one of the exclusions that makes it legal
[21:34] <amell> gb_g6gzh: if you have a decode with an altitude of 2m that would be particularly useful :)
[21:34] <SilverIV7> makes sense
[21:34] <SpeedEvil> A small glider can be a 'small unmanned aircraft' - but those can only do certain things - and fly out of visual range of the operator is not one of them
[21:34] <db_g6gzh> amell: http://paste.debian.net/100881/
[21:35] <mikestir> I think the operator has also to be able to kill the autopilot on remote
[21:35] <SpeedEvil> mikestir: the operator has to be in control at all times.
[21:35] <SilverIV7> Okay, would onboard live feed video cameras get around that or would it still physically need to be within sites range?
[21:35] <SpeedEvil> This doesn't say that you can't have it on autopilot - but it does say that you have to be able to remove the control
[21:35] <SpeedEvil> SilverIV7: unassisted visual range
[21:36] <SpeedEvil> The only way round it is a helicopter with you in.
[21:36] <mikestir> SilverIV7: see james may's toy stories - the one about the glider
[21:36] <SpeedEvil> (which one TV...
[21:36] <mikestir> they had to follow it in a helicopter with the remote

[21:37] <db_g6gzh> amell: sadly not down to 2m - signal went very quickly towards the end of that last one

[21:54] <db_g6gzh> good 8-)

[22:05] <Willdude123> That is one realistic crop circle
[22:08] <chrisstubbs> good luck amell!
[22:08] <chrisstubbs> I imagine it bounced a bit hitting the ground at 13m/s

[22:18] <craag> sub0: There's various guides on many of steps

[23:24] <craag> People in the know: I'm wanting to play around with stm32f0, should I get a discovery board or nucleo board?
[23:24] <craag> Is there any real difference?
[23:28] <arko> discovery board is crap
[23:28] <arko> poorly documented really
[23:28] <arko> never messed with the nucleo though

[23:35] <craag> Hmm ok
[23:37] <Laurenceb> lulwut arko
[23:37] <Laurenceb> to be fair discovery has slightly annoying pin header
[23:37] <Laurenceb> othe rthan that i use it for all my projects

[23:37] <craag> Yeah I'm seeing that the nucleo has more standard headers
[23:37] <craag> in addition to the 'arduino-compatible' headers
[23:37] <Laurenceb> hehe
[23:38] Action: Laurenceb zzz
[23:39] <craag> Meh I'll get a nucleo to try it out, and get the top-end discovery board if I like it.

[23:48] <aadamson> I have mostly discovery boards, with a couple of nucleo's, I much prefer the discoverys
[23:48] <aadamson> craag, but check and see, the f0 discovery if I remember right is pretty limited... (ram/flash), some of the other M0 or M0+ boards have more
[23:49] <aadamson> ah the stm32f0discovery might be ok, it's 64kflash/8kram

[23:52] <craag> Yeah I was looking at the range and like the idea of trying out the onboard USB after I get to grips with the basics of it (hence looking at the 072 DISCO
[23:52] <aadamson> I didn't see an L0 (m0+) discovery so maybe they don't have one
[23:52] <craag> aadamson: Being released this summer I believe :)
[23:53] <aadamson> ah indeed, that is 128k
[23:53] <aadamson> much better

[23:53] <craag> It's to look into replacing AVRs, so really >32k flash and >4k ram is fine!

[23:58] <craag> I've got one application where a lot of RAM would be nice, so an M3 might be suitable, but that might be getting a bit ahead of myself before I've even tried the platform!
