[00:02] <Vaizki> DT isn't so bad when you are setting out on a purpose built device project and you actually design it before you boot linux..
[00:02] <Laurenceb> haha true
[00:03] <Vaizki> but for a generic use play around and try stuff out type of mucking about it's a bit painful yes
[00:03] <Laurenceb> I was trying it on beaglebone
[00:03] <Laurenceb> " purpose built device" " actually design it"
[00:04] <Vaizki> not sure about the state of BBB linux distros today but they really should have a default DT with all the pins used for peripherals so you get I2C, SPI, PWM, GPIO etc out of the box
[00:05] <Vaizki> then if you need to change the pinmux, ok you have to start mucking about with DT

[00:05] <Laurenceb> lol no
[00:05] <Laurenceb> GPIO and PWM work.. some of the time
[00:05] <Vaizki> https://dl.dropboxusercontent.com/u/367935/ouman-pi-tuning.png
[00:06] <Laurenceb> BBB: making rpi look well designed
[00:06] <Vaizki> ack wrong paste / channeö
[00:07] <Vaizki> both have their issues, I like a lot of stuff on the BBB but there's some weird stuff also
[00:08] <Laurenceb> like no functional PMIC
[00:08] <Laurenceb> and a bunch of vregs that start drawing 50mA when the thing says its turned off
[00:09] <Vaizki> yea that pmic/sleep/lipo-use etc power side is a mess
[00:09] <Laurenceb> my BBB looks like enamled wire spaghetti now its finally all fixed
[00:10] <Laurenceb> it is possible to make everything work correctly, but a ton of PMIC traces need cutting and rerouting
[00:10] <Vaizki> but it had a decent ethernet on it, fast emmc and loads of I/O pins
[00:10] <Laurenceb> yes, its so stupid
[00:10] <Laurenceb> what could have been a really pro board wrecked by n00b mistakes
[00:11] <Vaizki> what I don't get is why they didn't fix it
[00:11] <Laurenceb> yeah
[00:11] <Vaizki> I mean they made several revisions.. and it's "open source" so someone could have fixed it for them..
[00:12] <Laurenceb> one thing I didnt fix the the RTC
[00:12] <Laurenceb> wasnt going to compile a new kernel
[00:12] <Vaizki> well that's the easy part of things..
[00:12] <Laurenceb> I stuck it a boot script to configure the PMIC correctly over i2c
[00:12] <Vaizki> takes a while but.. :)
[00:12] <Laurenceb> well I'd also have needed a driver for it...
[00:12] <Vaizki> yea me too
[00:12] <Laurenceb> ah cool
[00:13] <Laurenceb> I was going to write some documentation on how to fix BBB, sounds like you got there by yourself :D
[00:13] <Vaizki> naah I didn't fix the PMIC wiring, just the registers over i2c
[00:14] <Vaizki> but I have to sleep.. badly..
[00:14] <Laurenceb> ok I should write it up then... if I can remeber what i did
[00:14] <Laurenceb> cya
[00:14] <Vaizki> still can't decide on a freq counter though :(
[00:14] <Vaizki> maybe it will come to me in a dream

[09:20] <fl_0> what prevents dl-fldigi from showing distance and bearing for my payload?
[09:20] <fl_0> it worked yesterday when I had it running under "CHANGEME"
[09:20] <fl_0> now I set a callsign but this cannot be the reason for not working, does it?
[09:20] <fsphil> it needs a valid payload document
[09:21] <fsphil> setup a document, describe each field. it should appear in the "testing" list in dl-fldigi
[09:21] <fl_0> it does
[09:21] <fl_0> and I selected it
[09:21] <fsphil> select it and hit autoconfigure
[09:21] <fsphil> that *should* get the lat/lng parsing working
[09:21] <fl_0> do each of the fileds have to be present?
[09:22] <fsphil> yeah it has to match
[09:22] <fl_0> i just disabled the pressure sensor ...
[09:22] <fl_0> ok
[09:22] <fl_0> then it was valid for "CHANGEME" by chance then ....
[09:22] <fl_0> :D
[09:24] <fl_0> can old paylopad docs be deleted by myself?
[09:25] <daveake> no
[09:25] <fl_0> :)
[09:25] <fl_0> hi daveake
[09:25] <fsphil> information can't be destroyed
[09:25] <AndyEsser> only transferred from one form to another
[09:26] <daveake> Well, you could try calling your payload $$RM-RF_*
[09:26] <daveake> $$DROP_TABLE_PAYLOADS
[09:26] <fl_0> :)
[09:26] <AndyEsser> :)
[09:26] <AndyEsser> Aww, little bobby tables
[09:26] <daveake> :)
[09:26] <craag> though of course that old fashioned sql nonsense won't work on habitat ;)
[09:27] <AndyEsser> It's couchdb?
[09:27] <craag> aye
[09:27] <AndyEsser> fine
[09:27] <daveake> now you're being sensible and accurate
[09:27] <AndyEsser> HTTP 1.1
[09:27] <AndyEsser> DELETE /
[09:27] <AndyEsser> :P
[09:27] <craag> noooooo
[09:27] <craag> all those typoed payload docs..
[09:27] <craag> how could you??!??!
[09:27] <AndyEsser> A presume you have a valid backup.... yes?
[09:27] <AndyEsser> :P
[09:28] <craag> backups are for the weak
[09:28] <SpacenearUS> New vehicle on the map: 03DL0CRE-11 - 12http://tracker.habhub.org/#!qm=All&q=DL0CRE-11
[09:28] <AndyEsser> you mean, "backups are for the week"
[09:28] <AndyEsser> ie weekly?
[09:28] <AndyEsser> :P
[09:28] <fl_0> ahhhwww
[09:28] <fl_0> found it
[09:28] <fl_0> :)
[09:28] <craag> no, the week when it was being written.
[09:28] <craag> haven't run them since :P
[09:29] <AndyEsser> o good lord
[09:29] Action: AndyEsser runs over with floppy disks
[09:29] Action: craag surrounds the server box with magnets
[09:30] <daveake> I remember one customer who dutifully made backups on floppies
[09:30] <daveake> However he'd bought hard-sectored ones
[09:30] <daveake> i.e. hole every sector not once per revolution
[09:30] <craag> (fyi im nothing to do with writing or running habitat)
[09:30] <daveake> So yes he had a backup, but the sectors were scattered around
[09:31] <fsphil> hole?
[09:31] <daveake> hole so it could sync with the start of the track
[09:31] <fsphil> don't think I've ever seen that
[09:32] <daveake> https://en.wikipedia.org/wiki/Hard_sectoring
[09:32] <daveake> Was rare
[09:32] <gonzo_> usual thing is to do backups and never test them. (been there)
[09:33] <fsphil> I've a box of 5.14 discs, must take a look
[09:33] <chris_99> interesting, never heard of that before
[09:33] <gonzo_> these days the only usable backup media for a HD is another HD
[09:34] <craag> are tapes out of fashion now?
[09:34] <AndyEsser> craag: depends
[09:34] <gonzo_> still seem to use them at work
[09:34] <AndyEsser> You still can't really beat tapes for Storage/Cost
[09:34] <gonzo_> there is a safe full of them
[09:34] <chris_99> i got this fluid with iron powder in to try to image a floppy disk, but it wasn't fine enough alas - https://www.anfractuosity.com/wp-content/uploads/2015/08/2015-08-05-195008.jpg
[09:34] <AndyEsser> even with the plummeting cost of HDDs
[09:34] <fsphil> tapes are annoying when they get tangled up in the machine. doesn't happen too often thankfully
[09:34] <AndyEsser> fsphil: thankfully never had that happen :)
[09:35] <AndyEsser> the annoying bit with tapes is the read speed
[09:35] <AndyEsser> but thankfully, restoring from backup is a rare task
[09:35] <AndyEsser> unless you have muppet users, or frequent natural disasters
[09:35] <AndyEsser> :)
[09:35] <daveake> For important stuff (source code etc) I have dropbox on several machines, and git for versioning
[09:35] <AndyEsser> daveake: o god
[09:35] <gonzo_> you used to be able to get an little ampule with a ferro liquid, you could use it to look at mag stripes on cards
[09:35] <AndyEsser> *shudders* at dropbox
[09:35] <daveake> Bulk stuff (mp3s, videos) they're on a raid nas with USB HD backup
[09:35] <fsphil> just had it happen once AndyEsser. took a few hours to clear it out
[09:36] <fsphil> we've moved to external SATA discs now
[09:36] <AndyEsser> sounds fun for you :)
[09:36] <chris_99> gonzo_, https://www.anfractuosity.com/projects/optical-magnetic-stripe-reading/ i wrote a little proggy to decode cards via that
[09:36] <gonzo_> I have nightly rsync between lots of machines
[09:36] Action: craag -> nas -> s3 glacier
[09:36] <AndyEsser> my mission critical stuff (source code, server configs, etc) is all in git, which is on Amazon, and the disks are backed up to S3 and Glacier
[09:36] <AndyEsser> and then my DB's are backed up nightly to S3 and glacier as well
[09:36] <daveake> Also automated source backups each night to another raid nas + usb hds
[09:37] <gonzo_> for mp3's etc, the rsync runs to a friends house. A few of us have a common library of music. It saves all that 'have you heard/did I give you a copy of....'
[09:37] <AndyEsser> ha
[09:37] <AndyEsser> nice
[09:37] <daveake> and AJC to backup on-the-fly
[09:38] Action: AndyEsser ponders having payload backup all data direct to Amazon on launches....
[09:39] <fsphil> put wifi on it. if it gets stuck in a tree, just rsync and leave it there
[09:39] <daveake> I had one ftp-ing photos after landing
[09:39] <AndyEsser> haha
[09:40] <AndyEsser> fsphil: I'm so going to lose my first payload
[09:40] <daveake> except it rebooted on landing and thought it hadn't launched yet ...
[09:40] <AndyEsser> and will just end roaming EA looking for this box
[09:40] <AndyEsser> daveake: ooo
[09:40] <AndyEsser> lose connection?
[09:40] <AndyEsser> or something it a reset switch?
[09:40] <AndyEsser> loose*
[09:40] <AndyEsser> hit*
[09:40] <daveake> battery holder and not enough gaffer tape
[09:40] <AndyEsser> my god.... bad typing today
[09:40] <AndyEsser> haha
[09:41] <fsphil> landing tests all your connections
[09:41] <daveake> But it did reconnect to 3G and stream the video of its own recovery
[09:41] <fsphil> it's one of the few good things about trees. they soften the landing
[09:41] <AndyEsser> fsphil: I planned on doing the highly scientific method of throwing my payload out of my upstairs windows...
[09:41] <daveake> :)
[09:41] <fsphil> excellent
[09:41] <AndyEsser> I think it was daveake's blog that mentioned that if it can't handle falling down stairs, it can't handle the landing
[09:42] <AndyEsser> so started coming up with test ideas :P
[09:42] <craag> aka. the ed moore test
[09:42] <daveake> That's the Ed Test
[09:42] <AndyEsser> haha
[09:42] <daveake> Often executed mentally rather than physically
[09:42] <fsphil> you don't have to actually do it :)
[09:42] <AndyEsser> ah "Do I think this will work ok if I were to throw it down the stairs"?
[09:42] <fsphil> my second payload failed the ed test. the antenna was too pansy
[09:43] <AndyEsser> speaking of which
[09:43] fab4space (~fab4space@ left irc: Ping timeout: 240 seconds
[09:43] <fsphil> and then failed to be tracked after launch
[09:43] <daveake> ouch
[09:43] <AndyEsser> I presume people don't use proper commercial grade antenna on their payloads, but more likely just cable?
[09:43] <daveake> Hand-made 1/4-wave performs better than anything you might buy
[09:44] fab4space (~fab4space@ joined #highaltitude.
[09:44] <gonzo_> one of my projects got thrown off the fire escape onto the factory floor, by the boss, to test it's drop resistance. Then had to tell him it was the only prototype
[09:44] <craag> and is a heck of a lot lighter / less lethal
[09:44] <AndyEsser> craag: yea...
[09:44] <AndyEsser> gonzo_: I was talking to my MD yesterday about this HAB stuff, he seemed fascinated by it
[09:44] <AndyEsser> I'm hoping he'll let me borrow his Land Rover for recovery ;)
[09:44] <fsphil> spikes falling at speed from 30km is bad
[09:45] <craag> "ernie ball custom guage 13" is fantastic antenna element material
[09:45] <craag> tin-plated steel guitar wire
[09:45] <gonzo_> I use bits of cat5 for my hab ants. Just rememner to straighten them out before release
[09:45] <daveake> I have quite a few commercial ones here, all tested, and all outperformed by a 1/4 wave
[09:45] <AndyEsser> that's just crazy
[09:45] <daveake> Open up a commercial one and see what you find
[09:45] <fsphil> wouldn't recommend cat5 gonzo_. it's quite fragile
[09:46] <AndyEsser> Really need to get started on actually building things and testing :(
[09:47] <gonzo_> the pure copper stuff is ok
[09:47] <fsphil> they kept breaking on me
[09:47] <fsphil> might've just been poor cable I had
[09:47] <gonzo_> the ali clad stuff is poor
[09:48] <AndyEsser> use Cat5
[09:48] <AndyEsser> but not as an atenna
[09:48] <AndyEsser> as an actual link :P
[09:48] <AndyEsser> reallllllly long coil of it beside you as you launch :P
[09:48] <daveake> I've seen that seriously suggested
[09:48] <AndyEsser> (we'll ignore the 100m max range of cat5 for the sake of argument)
[09:48] <daveake> By idiots
[09:48] <fsphil> gigabit download speeds. from 30m altitude
[09:48] <gonzo_> think you would reach max alt quite quick withj a box of cat5
[09:48] <gonzo_> hehe yep, max-30mtrs
[09:48] <daveake> Not at all
[09:48] <AndyEsser> hehe
[09:49] <daveake> Judjing by recent events
[09:49] <daveake> Extra weight = mega altitude
[09:49] <gonzo_> at least it would be notem exempt
[09:49] <AndyEsser> ha
[09:50] <fsphil> think the best bet for really high data rate is 2.4ghz and a huge antenna on the ground with auto tracking
[09:50] <gonzo_> but cat5 strands would be fine as a gorundplane. Nice and light. And would probably be taped to the payload so not flexing
[09:50] <fsphil> yeah they'd have to be secured
[09:50] <gonzo_> and a bit of 16/0.2 for the element if you prefer
[09:52] <gonzo_> but mine have all been just free space gp elemens soldered to the ntx2 case and the radiating soldered to the ntx2 pcb. All cat5 solid copper. Then wrapped in bubble wrap with the elenmts poking out
[09:52] <gonzo_> performed fine and even whenb flexed about a bit have showed no sign opf prob
[09:54] <gonzo_> these are all pico flights where there is no possability of the payload bouncing along the groung at release
[09:54] <fl_0> is there a way to see a little more of the telemtry?
[09:54] <gonzo_> (ok, that's prob on daves list)
[09:54] <fl_0> i have too much sensors :)
[09:54] <daveake> see more where?
[09:54] <fl_0> i have the tracker opened
[09:55] <daveake> yes you can edit the source code
[09:55] <fl_0> with the telemetry grpah at the bottom
[09:55] <daveake> it trims the lines to stop line-wrap

[09:55] <fl_0> http://tracker.habhub.org/#!mt=roadmap&mz=9&qm=1_day&mc=51.56897,8.2566&f=DL0CRE-11
[09:56] <daveake> so what "more" do you want to see ?
[09:56] <fl_0> the current values for the external temperature is not shown in the list
[09:57] <daveake> it is
[09:57] <daveake> You have 3 temperatures
[09:57] <fl_0> jepp
[09:57] <AndyEsser> fl_0: I can see Temperature, Temp External and Temp Internal
[09:57] <daveake> PITS internal, DS18B20 external, BMP180 external
[09:58] <daveake> So you have all 3
[09:58] <fl_0> just a second
[09:58] <fl_0> will make a lilte pic
[10:00] <fl_0> http://picpaste.de/5967f3fb92964540ce03a29e39dc904d.png
[10:00] <fl_0> see here
[10:00] <fl_0> the list is somewhat trunkated
[10:00] <fl_0> and i thought there may be a separate page where we could see more details
[10:02] <daveake> I don't understand
[10:03] <daveake> All your live data is on that habhub page
[10:03] <fl_0> hmm
[10:03] <fl_0> I miss the graph for "external temp"
[10:04] <daveake> no idea
[10:05] <daveake> ping lz1dev
[10:05] <daveake> ask him ^ :)
[10:06] <fl_0> kk
[10:06] <fl_0> will wait for him :)
[10:06] <fl_0> until then APRS wants to be debugged ...
[10:06] <fl_0> again thanks for the support guys
[10:06] <fl_0> it is much appreciated
[10:07] <daveake> Anyone have the link to x-f's live/graphing page ?
[10:07] <Geoff-G8-> http://x-f.lv/dev/habitat-graphs/payload/DL0CRE-11
[10:07] <daveake> Cheers :)
[10:07] Nick change: Geoff-G8- -> Geoff-G8DHE-Lap
[10:08] <Geoff-G8DHE-Lap> The data is there
[10:08] <fl_0> woohaa
[10:08] <fl_0> that looks excellent
[10:08] <fl_0> thank you
[10:08] <fl_0> that is what i was looking for =)
[10:08] <AndyEsser> Very cool :)
[10:09] <AndyEsser> So as long as I pump all my telemetry to dl-fldigi - I can use all sorts of funky tools people have made/
[10:09] <AndyEsser> ?*
[10:09] <daveake> Yeah there's lots of stuff
[10:09] <AndyEsser> That's so cool
[10:09] <AndyEsser> :)
[10:09] <daveake> You can also export from habitat into (spit) Excel or whatever
[10:09] <AndyEsser> The massive nerd and trekkie in me is loving all this stuff
[10:09] <AndyEsser> haha
[10:10] <AndyEsser> Can't wait to get properly stuck in - crosses so many disciplines that I have interest/knowledge in
[10:10] <AndyEsser> roll on xmas break from work :)
[10:10] <daveake> Yeah that's what got me hooked ...
[10:10] <daveake> ... coding, electronics, radio, photography, sniffing glue ...
[10:10] <daveake> er ...
[10:10] <AndyEsser> haha
[10:11] <AndyEsser> so, when I recently got back into electronics, I've been doing it all at my dining room table
[10:11] <AndyEsser> bought myself a soldering iron on the weekend
[10:11] <daveake> Actually the craft side - making nice payloads - is also fun
[10:11] <AndyEsser> to do some of the fiddly bits
[10:11] <AndyEsser> looked up... smoke detector directly above table
[10:11] <AndyEsser> whoops :P

[10:31] <fsphil> we don't even see the typos anymore

[10:32] <chris_99> hehe
[10:33] <AndyEsser> So this morning we've had a Little Bobby Tables and a Matrix reference
[10:33] <AndyEsser> I have found my people :)
[10:33] <daveake> People come for the HAB but stay for the nerdism
[10:34] <AndyEsser> So quote tastic :)
[10:34] <AndyEsser> Another channel I'm in, one of the bots has a quote system built in
[10:34] <AndyEsser> I'd have used it about 3 times this morning already :)

[10:35] <chris_99> mmm heh
[10:35] <AndyEsser> that, along with the whole "Lets outlaw encryption"
[10:35] <fl_0> aprs.wav: No such file or directory
[10:35] <AndyEsser> like seriously... who is advising them
[10:35] <chris_99> goodness knows
[10:35] <fl_0> where shopuld that be generated?
[10:35] <fl_0> in the tracker folder, right?
[10:35] <daveake> yes tracker folder
[10:35] <fl_0> hm k
[10:35] <daveake> tracker program makes it
[10:36] <daveake> send_aprs uses/deletes it
[10:36] <daveake> the end. Checked it just now.
[10:36] <daveake> What APRS callsign have you put in?
[10:36] <fl_0> same as the payload
[10:36] <fl_0> DL0CRE
[10:36] <daveake> wrong
[10:36] <fl_0> and 11 as SSID
[10:36] <daveake> oh not the same then
[10:37] <fl_0> ?
[10:37] <fl_0> DL0CRE-11 is tha payload callsign
[10:37] <daveake> Sometimes people add the -11 to the callsign
[10:37] <fl_0> ah k
[10:37] <fl_0> nope
[10:37] <daveake> which is wrong as that's what the ID line is for
[10:37] <fl_0> APRS_Callsign=DL0CRE
[10:37] <fl_0> APRS_ID=11
[10:37] <fl_0> APRS_Period=1
[10:37] <daveake> fine
[10:37] <fl_0> so that is correct then
[10:42] <fl_0> send_aprs: line 16: echo: write error: Resource temporarily unavailable
[10:42] <fl_0> ah
[10:42] <daveake> SD card
[10:42] <daveake> ?
[10:44] <fl_0> Free SD space = 12281.6MB
[10:44] <AndyEsser> not sure that's enough :)
[10:44] <fl_0> hrhr
[10:44] <fl_0> i guess it is
[10:44] <fl_0> seems like the aprs.wav is not generated
[10:44] <fl_0> i commented out the "rm -rf"
[10:44] <daveake> That line #16 is this:
[10:44] <daveake> echo Sending APRS Packet
[10:44] <fl_0> but still no file in that dir
[10:45] <daveake> Not entiirely sure how that can fail :/
[10:45] <fl_0> mee to
[10:45] <fl_0> me too
[10:45] <fl_0> because its -e aprs.wav before
[10:45] <fl_0> that wouldn't be executed if no file was there ....
[10:45] <daveake> yup
[10:46] <daveake> Any chance you've got 2 copies of that script running?
[10:46] <fl_0> of "tracker"?
[10:47] <daveake> No, send_aprs. tracker is an executable not a script.
[10:47] <fl_0> aaahhh
[10:47] <fl_0> yes
[10:47] <daveake> yes you have?
[10:47] <fl_0> seems like some zombies
[10:47] <fl_0> i have
[10:47] <fl_0> yes
[10:47] <fl_0> will kill them
[10:47] <daveake> well there you go
[10:47] <fl_0> :)
[10:48] <daveake> dunno how you managed it, but hey
[10:48] <daveake> tbh I'd scratch the SD and start again if I were you
[10:49] <daveake> It's quicker than trying to fix whatever's happened since you did it first time
[10:49] <daveake> New SD takes half an hour and I know that you (and I) have spent more time than that on it last night and this morning
[10:50] <AndyEsser> What do people recommend as the MCU/CPU to use for onboard flight recorders?
[10:50] <fl_0> jepp
[10:50] <fl_0> daveake: will definitely do that before lauch
[10:50] <fl_0> *launch
[10:50] <fl_0> but learned a lot
[10:50] <daveake> Whatever a) does the job (anything) and b) you know about
[10:50] <fl_0> at least myself
[10:50] <fl_0> :D
[10:51] <daveake> If you don't want to download live images then almost any AVR or little PIC will do it
[10:51] <AndyEsser> Yea, had looked at a PIC32, but designing the PCB for it was a ballache
[10:51] <AndyEsser> did look at maybe an ARM SOC
[10:51] <AndyEsser> but it's the same form factor, so a pain to design the PCB for
[10:51] <daveake> Even a lowly AVR probably spends 90%+ of its time idling
[10:52] <AndyEsser> http://www.atmel.com/products/microcontrollers/avr/
[10:52] <AndyEsser> these?
[10:52] <daveake> Me, I jsut buy an Arduino, get it to work, then get Upu to make it into a board :)
[10:53] <Vaizki> 328p is the most used (unsurprisingly)
[10:54] <AndyEsser> http://www.atmel.com/devices/atmega328p.aspx
[10:54] <AndyEsser> one of those?
[10:56] <pb0ahx> !flights
[10:56] <SpacenearUS> 03pb0ahx: There are no flights currently :(
[10:57] <daveake> yes one of those
[10:58] <fsphil> avr's are handy. they are so simple
[10:59] <fsphil> that apostrophe doesn't look right
[11:00] <daveake> 'cos it's not :)
[11:00] <Vaizki> AndyEsser, for avr you will find a load of ready libraries and example code including ready made tracker examples etc.. but if I was to do an ambitious clean design from scratch now it'd be a Cortex-M0 probably
[11:01] <Vaizki> you can even get them in DIP packages if you are surface-mount challenged like me :)
[11:01] <daveake> Those Pis about to get docked with the ISS http://www.ustream.tv/nasahdtv
[11:02] <Darkside_> oh what
[11:02] <nick_> If you want low power go for M0+
[11:02] <Darkside_> for use on the ISs?
[11:02] <daveake> for small values of "use", yes
[11:02] <AndyEsser> heh
[11:02] <Darkside_> hah ok
[11:02] <AndyEsser> Vaizki: ready made is bad for me :P
[11:02] <daveake> education/school stuff
[11:04] <AndyEsser> Vaizki: thanks for the headsup about the DIP packages! Big headache solved
[11:04] <fsphil> stm32l0 would be a fun payload cpu
[11:04] <fsphil> very low power
[11:05] <nick_> I've got a coin cell STM32L0 board on my to do list.
[11:05] <fsphil> I've a little board to build for monitoring a solar power thing, seems ideal
[11:05] <nick_> I don't know that it could handle GPS though.
[11:06] <fsphil> gps is just a small string every few seconds. easy peasy
[11:06] <fsphil> a 6502 could do it :)
[11:06] <daveake> Well volunteered :)
[11:06] <AndyEsser> fsphil: is that what most GPS chips output? just a serial string of coords or something?
[11:06] <AndyEsser> Haven't got that far into looking at the datasheets
[11:06] <daveake> By default yes
[11:06] <daveake> NMEA
[11:06] <AndyEsser> sahweet
[11:06] <AndyEsser> Yep, saw the mention of NMEA, again, haven't had a chance to dig into it all yet
[11:06] <fsphil> they also offer brand-specific protocols
[11:06] <AndyEsser> there is a limit to info consumption
[11:06] <AndyEsser> sadly
[11:06] <fsphil> ublox's UBX is quite simple too
[11:07] <daveake> yeah main problem is switching of the NMEA so it doesn't get in the way of the UBX :)
[11:07] <daveake> off
[11:08] <fsphil> the stm chips also have multiple uarts, so rtty could be done entirely in hardware
[11:08] <Vaizki> I think ubx is simpler than NMEA...
[11:08] <fsphil> really the cpu would be asleep 99% of the time
[11:08] <Vaizki> and UBX runs nicely over i2c in polled mode so you will only get data when you need/ask
[11:09] <Vaizki> i.e. just before starting RTTY sentence sending
[11:09] <daveake> yeah I tend to poll every second anyway, so it can be logged, but yes you can just poll shortly before the RTTY sentence is built
[11:10] <AndyEsser> RTTY is the default data-over-radio protocol that people use, correct?
[11:10] <daveake> yes
[11:10] <fsphil> it is the simplest
[11:10] <Vaizki> well that's the default that everyone is ready to receive :)
[11:10] <nick_> fsphil: I mean if the coin cell could provide enough power for the GPS over a flight.
[11:10] <gonzo_> that is 7/8 but ascii rtty. Not to be confused with 5bit batdot
[11:10] <gonzo_> baudot
[11:10] <fsphil> nick_: ah, yes. I misunderstood
[11:11] <daveake> ditto
[11:12] <gonzo_> (I was going to do a baudot flight, just for fun, but I think there was one chr short for the packet framing)
[11:12] <fsphil> it has no *
[11:12] <fsphil> though dl-fldigi is hacked to use something else
[11:12] <fsphil> can't remember what that was now. should be in the source
[11:12] <gonzo_> we did look at the time
[11:12] <Vaizki> noooo don't go into the souuuuurce
[11:13] <daveake> you're ina maze of twisty passages, all alike
[11:13] <AndyEsser> anyone know the difference between the AVR 328 PN and PU?
[11:13] <fsphil> it is inevitabile
[11:13] <gonzo_> a hamming distance of 6?
[11:13] <gonzo_> you are in a room, there are exits N S E. Command:

[11:15] <fsphil> gonzo_: for baudot you can use # in place of *
[11:16] <gonzo_> sure we tried that?? was the problem downstream at habhub?
[11:16] <fsphil> AndyEsser: temperature range
[11:16] <SA6BSS-Mike> AndyEsser: http://forum.arduino.cc/index.php?topic=98956.0
[11:16] <AndyEsser> fsphil: that's basically all I noticed
[11:16] <AndyEsser> thanks
[11:17] <AndyEsser> SA6BSS-Mike: thanks
[11:30] <AndyEsser> at least with a DIP package I can order the IC and use breadboard in the meantime :)
[11:34] <daveake> gah he said breadboard :p
[11:34] <AndyEsser> sorry
[11:34] <AndyEsser> :P
[11:34] <AndyEsser> Ed would confirm that I hated breadboard at school :P
[11:34] <daveake> s'ok, I hate them :)
[11:34] <AndyEsser> I used custom PCB's for EVERYTHING
[11:34] <AndyEsser> must've spent a fortune
[11:34] <AndyEsser> but now the cost lands on me... I'm a bit more careful ;)
[11:35] <daveake> They just add capacitance and inductance, with random disconnects, to what would otherwise be a lovely working circuit :)
[11:35] <daveake> and crosstalk
[11:35] <AndyEsser> Yea, it was the capacitance and inductance that caused me a problem with my GCSE project
[11:35] <AndyEsser> for some reason decided to make a 4-channel video switch...
[11:35] <AndyEsser> ha
[11:36] <daveake> :)
[11:36] <AndyEsser> was thinking about my GCSE electronics the other day
[11:36] <AndyEsser> I remember starting to work on a program for the PIC to understand OpenGL
[11:37] <AndyEsser> I guess... I realised there was a need for OpenGL ES before it was released
[11:37] <AndyEsser> ha
[11:43] <AndyEsser> Do people typically use the altitude reportd from a GPS chip, or a standalone altimeter?
[11:44] <mattbrejza> what altimeter were you thinking of?
[11:45] <mattbrejza> (normally gps though)
[11:45] <AndyEsser> Well presumed you could get IC's that measure altitude (although I guess that might be based on atmospheric pressure - so more like a barometer)
[11:46] <AndyEsser> Again, sorry for _ALL_ the questions :P Just want to avoid any common pitfalls
[11:46] <daveake> sore point lately :/
[11:46] <chris_99> heh, did anyone hear any more about that Italian balloon
[11:46] <AndyEsser> daveake: o?
[11:46] <daveake> No reply on FB (but they did see my question)
[11:46] <daveake> All comments deleted on YT
[11:46] <AndyEsser> Is this the Italian balloon claiming a new record?
[11:46] <daveake> yep
[11:47] <chris_99> daveake, muchos suspect
[11:47] <daveake> They're still claiming 49,500
[11:47] <Vaizki> AndyEsser, pressure is so low up there that you need a high end barometer .. really high end
[11:47] <daveake> I'm assuming they just don't understand
[11:47] <AndyEsser> Vaizki: gotcha
[11:48] <daveake> Also, pressure changes with time even at the same altitude
[11:48] <Vaizki> yea you need a weather model..
[11:48] <AndyEsser> ok ok - I'll stick with GPS :P
[11:48] <daveake> yes :)
[11:48] <fsphil> even gps altitude is a bit inaccurate, but close enough
[11:48] <Vaizki> a gps in flight mode
[11:48] Action: AndyEsser adds a zero to altitude
[11:49] <daveake> yeah, but 10's of metres not 1000's :p
[11:49] <AndyEsser> can anyone recommend an AVR programmer? Or do people tend to do it in-circuit?
[11:50] <daveake> This one https://www.kanda.com/products/Kanda/AVRISP-MKII.html?google=gb&gclid=Cj0KEQiAv5-zBRCAzfWGu-2jo70BEiQAj_F8oJcdFv5K38ws7B7gKISZcdXqRwmg8LTcpVhhnA6TYQYaAhEs8P8HAQ
[11:50] <fsphil> in-circuit is the way to go
[11:50] <daveake> absolutely
[11:50] <AndyEsser> fsphil: in-circuit would be my preferred
[11:51] <AndyEsser> so, it's been a LONG time since I did any programming for microcontrollers, when I was using PIC16's and stuff, in-circuit ended in a serial port, which then went into our PC's
[11:51] <fsphil> I have one of these too, has worked well: https://www.olimex.com/Products/AVR/Programmers/AVR-ISP500/
[11:51] <AndyEsser> is it still basically the same?
[11:51] <AndyEsser> but with a USB->Serial adapter for the PC?
[11:51] Action: AndyEsser loads above page
[11:51] <fsphil> nah they're all USB these days
[11:52] <fl_0> daveake: I found the issue
[11:52] <fl_0> its here:
[11:52] <fl_0> RandomOffset = rand() % Config.APRS_Random;
[11:52] <fsphil> avrdude is the usual bit of software to flash them, it'll work with both those programmers
[11:52] <fl_0> the problem is/was that APRS_Random is undefined (by default)
[11:52] <fl_0> so that operation fails
[11:53] <fl_0> if I set the parameter, all is fine
[11:53] <daveake> ah yes, I forgot that got fixed :/
[11:53] Action: fsphil still wishes there was an stm32dude
[11:53] Action: fsphil should make it
[11:53] Action: fsphil is to lazy
[11:53] <fl_0> It got fixed?
[11:54] <daveake> in next version
[11:54] <fsphil> +o
[11:54] <fl_0> At least not inthe git repo?
[11:54] <fl_0> ah k
[11:54] <fl_0> I just made a pull request ...
[11:54] <fl_0> :)
[11:54] <daveake> ok
[11:56] <AndyEsser> right, might be time to place another order in...
[11:57] <AndyEsser> This stuff is sending me all right back to my childhood (stupid giddy feeling included)

[11:58] <fsphil> that'll go away after an all night session tracking down some obscure bug
[11:58] <AndyEsser> fsphil: Ha
[11:58] <AndyEsser> that's erm... actually what I love :)
[11:58] <fsphil> yeah me too
[11:59] <AndyEsser> You don't get that sort of sense of achievement when you write a python script to display a string to the screen
[11:59] <fsphil> debugging an entire program with a single LED
[11:59] <AndyEsser> but writing assembly, or c, or something, that controls physical hardware, that then drives motors etc :)
[11:59] <AndyEsser> fsphil: ha
[11:59] <AndyEsser> is that the MCU equivalent of a printf() debugging?
[11:59] <daveake> yup
[11:59] <fsphil> definitly
[12:00] <AndyEsser> time to learn morse code? :P
[12:00] <daveake> Even sending debug out of a serial port can mess up what your program is supposed to be doing
[12:00] <daveake> or make it work despite an actual bug

[12:01] <daveake> Hiis cat must be dead by now
[12:01] <AndyEsser> fsphil: damnit, beat me to it

[12:04] <fl_0> Theres just the carrier
[12:04] <daveake> disable device tree, please

[12:13] <fl_0> audio just comes from the earphone plug on the pi
[12:14] <fl_0> maybe an issue because it set the HAB board onto a Rapsberry Pi 2?
[12:14] <fl_0> due to some different GPIO numbering?!
[12:18] <daveake> Pi 2 doesn't work with that trick, no
[12:18] <fl_0> jepp
[12:18] <fl_0> made
[12:18] <fl_0> it
[12:18] <fl_0> replugged it to an A+
[12:18] <fl_0> and obviously works
[12:19] <daveake> I've not tried it yet, but wiringpi also offers pwm re-mapping function and that probably does work on the Pi 2
[12:19] <daveake> work a try
[12:19] <fl_0> i can try it
[12:19] <daveake> It's something like gpio mode <n> PWM
[12:19] <daveake> Run that then aplay the file
[12:20] <daveake> btw you will still get audio from the jack anyway; only one channel (left/right I forget which) is remapped
[12:21] <fl_0> yeah okay
[12:23] <AndyEsser> the AVR AT328's don't require an external clock do they?
[12:25] <daveake> Internal one might drift far enough to mess up rtty and/or GPS serial connection
[12:27] <gonzo_> that's a long way to drift!
[12:28] <daveake> 5% for an RC clock?
[12:29] <gonzo_> Ah, ok. that is getting interesting
[12:29] <gonzo_> stilldavid, 10% should be the limit for 8bit uart, assuming it was spot on central at the start
[12:30] <gonzo_> how did the david get in there??? must have ctrlC'ed
[12:30] <daveake> lol
[12:33] <AndyEsser> ha
[12:34] <AndyEsser> daveake: thanks, at least I can boot it up and play around with it without an external oscillator and then plan to build one in later
[12:34] <daveake> Just add a xtal
[12:35] <daveake> tbh for playing around, just buy an arduno mini pri
[12:35] <daveake> pro
[12:39] <mfa298> I think in some modes on the avr it's serial timing is already off from what it should be, so rc drift in one direction might improve timing, drift in the other might push it over the limit (from memory 9600baud on 8MHz clock is iffy - that might also be with clkdiv8 set)
[12:40] <AndyEsser> might as well just throw an xtal and required components onto this order then :)
[12:40] <daveake> yes
[12:40] <mfa298> and lots of 100nf caps for decoupling
[12:41] <AndyEsser> daveake: any recommended xtals off your head? or will any (with correct timing) do?
[12:41] <AndyEsser> mfa298: Already have like 600 caps :)
[12:44] <mfa298> You may want to run off 3v3 rather than 5v for the avr in which case you can't run at the full 20MHz (at least according to the datasheet)
[12:44] <AndyEsser> That is unsurprising, was going to just play around with 5v for the time being to simplify things, then shift to 3.3v after I got that hang of the AVR and bits

[14:14] <AndyEsser> Yea, was where my line of thinking was :)
[14:14] <AndyEsser> Hence the question
[14:14] <AndyEsser> ok, so it's fine to file a NOTAM for 7,8,9th June?
[14:14] <AndyEsser> etc
[14:14] <fsphil> it helps to add in your own restrictions. like weekend only, certain hours
[14:15] <fsphil> yeah
[14:15] <adamgreig> asking for a NOTAM for one weekend and then the following weekend is common
[14:15] <AndyEsser> and then clarify it further to say only between 1000 and 1200 or something
[14:15] <fsphil> I got every weekend in a month once, but don't start with that :)
[14:15] <AndyEsser> haha
[14:15] <adamgreig> they'll often ask you to let them know if you were able to launch on the first weekend, so they can cancel the second one
[14:15] <adamgreig> I wouldn't say between 1000 and 1200 on your first launch
[14:15] <AndyEsser> adamgreig: just let CAA know afterwards I guess?
[14:15] <AndyEsser> Well yea
[14:16] <AndyEsser> first launch would be like
[14:16] <adamgreig> just ask for a weekend and the weekend a week after is probably OK
[14:16] <AndyEsser> :)
[14:16] <fsphil> or make a pico and launch whenever you want
[14:16] <AndyEsser> what's the altitude before you have to file a NOTAM?
[14:16] <AndyEsser> fsphil: pico?
[14:17] <SpeedEvil> A balloon and payload which is entirely enclosed by a 2m sphere at all points in flight.
[14:17] <SpeedEvil> This does not require regulation
[14:17] <SpeedEvil> err - approval
[14:18] <chris_99> would that be the majority of balloons?
[14:18] <SpeedEvil> No.
[14:18] <adamgreig> it wouldn't be any latex balloons really
[14:18] <AndyEsser> well most balloons will go far beyond 2m at altitude surely?
[14:18] <SpeedEvil> Not just at launch
[14:18] <adamgreig> (there is some argument about the 100g but you're on shaky grounds..)
[14:18] <AndyEsser> SpeedEvil: so it's not alttude, it's "envelope" size?

[14:18] <AndyEsser> ah cool

[14:21] <daveake> You're in Cheshire?
[14:21] <AndyEsser> daveake: I am
[14:21] <daveake> Near Manc airport ?
[14:21] <SpeedEvil> 2m/s with 100g pawan gets to 16km
[14:21] <AndyEsser> "near" depends on terms
[14:21] <AndyEsser> but yes
[14:21] <SpeedEvil> which is a good test height perhaps
[14:21] <AndyEsser> I don't plan on doing any launches from here
[14:21] <daveake> You might want to move a bit
[14:21] <AndyEsser> haha
[14:21] <SpeedEvil> compared to a 35km/5m/s launch
[14:22] <daveake> I asked once for a launch at Jodrell Bank
[14:22] <daveake> "That would be tricky"
[14:22] <AndyEsser> for the exception of my "Throw out of window" launches, and chase car testing, I'm planning on doing most of my launches in Cambs/Oxford ways

[14:43] <AndyEsser> So... I'm having a moment here
[14:43] <fsphil> depends how close to ukhas2016 it is, if that happens
[14:44] <jonsowman> it'll happen
[14:44] <fsphil> sweet
[14:44] <AndyEsser> desperately trying to find out what frequency xtal I need for this AVR
[14:44] <fsphil> I should do something for it this time
[14:44] <fsphil> AndyEsser: if in doubt, 8mhz
[14:44] <AndyEsser> That's what I've got selected atm on Farnell - I just couldn't find out how Xtal frequency, related to CPU speed
[14:44] <AndyEsser> :(
[14:44] <daveake> But if you want it to run a decent speed, 8MHz
[14:45] <adamgreig> AndyEsser: on an AVR, the CPU speed equals the crystal frequency
[14:45] <adamgreig> on 5V you could use a 16MHz crystal, on 3.3V you should stick with 8MHz (I think 12 is also in-spec?)
[14:45] <fsphil> if you want a precise baud rate, 7.3728 mhz
[14:45] <AndyEsser> so an 8MHz xtal results in a CPU of 8MHz?
[14:45] <adamgreig> yep
[14:46] <adamgreig> (note that on more sophisticated microcontrollers and things that's not the case, they multiply up the crystal frequency to get the CPU speed)
[14:46] <AndyEsser> hm, so the 20 MHz that the AVR 328 says, is if I were to stick a 20 MHz xtal on the board?
[14:46] <adamgreig> yes
[14:46] <AndyEsser> ah ok
[14:46] <AndyEsser> thanks :)
[14:46] <fsphil> the avr has a clock prescaler, so it can be reduced
[14:46] <daveake> but not for 3.3V operation
[14:46] <daveake> (20MHz)
[14:47] <AndyEsser> ok, so 8MHz xtal, with a Vcc of 3.3v should give me 8MHz clock speed
[14:47] <fsphil> I've used both 8 and 7.3728 mhz with hab trackers
[14:47] <fsphil> fast enough to do basic jpeg processing
[14:48] <AndyEsser> fsphil: for those xtals, do you know the cap values to use, or are those fairly standardised regardless of frequency, as well?
[14:48] <fsphil> not counting the DCT, which to be fair is the slowest part of jpeg
[14:49] <fsphil> I just copied another schematic
[14:49] <adamgreig> the cap values depend on the specific crystal you buy, the datasheet for the crystal will tell you
[14:49] <AndyEsser> adamgreig: ah cool -t hanks
[14:49] <AndyEsser> :)
[14:49] <AndyEsser> err...
[14:49] <AndyEsser> thanks*
[14:49] <fsphil> I read some stuff on how to chose a crystal, and just confused myself more
[14:49] <AndyEsser> ha
[14:49] <AndyEsser> http://www.farnell.com/datasheets/314851.pdf
[14:49] <adamgreig> yea the capacitance on the crystal datasheet is often not the value of capacitor you should put on it
[14:49] <AndyEsser> I guess this is a dataSHEET in it's truest sense ;)
[14:50] <fsphil> http://www.st.com/web/en/resource/technical/document/application_note/CD00221665.pdf

[14:50] <fsphil> ooh good
[14:54] <AndyEsser> right, according to that super helpful page
[14:54] <AndyEsser> aiming for something like 50pF
[14:57] <AndyEsser> 47pF gives me a possible 'stray' capacitance of 6.5pF

[15:24] <AndyEsser> You got 99 problems, and the solutions aren't included?
[15:24] <AndyEsser> :P
[15:25] <adamgreig> AoE is quite good to read through and is really well suited to relative beginners i think
[15:25] <adamgreig> not as good a reference volume as i might have hoped
[15:25] <adamgreig> but it introduces everything you might want to know about electronics really
[15:25] <Vaizki> I don't count them, I just roll them in a ball and bitch about life in general
[15:25] <adamgreig> including a fair deal of reasonably serious stuff
[15:25] <chris_99> i was just looking to get the art of electronics but amazon themselves aren't selling it atm apparently
[15:26] <AndyEsser> chris_99: got a bookshop near you?
[15:27] <AndyEsser> Most should allow you to order books if you have the ISBN

[18:09] <AndyEsser> useless woman
[18:10] <AndyEsser> :P
[18:11] <Ian_> . . . you might lose all that expensive equipment . . . NASA might not have got going if discussed with the distaff side prior to making up their minds.
[18:12] <Ian_> When you get it all back, the risks are forgotten and you become hero for the day!
[18:12] <Lunar_LanderC> hello
[18:12] <Ian_> Hello!
[18:12] <AndyEsser> "We'll build this awesome rocket, but we're not atually going to send it up incase it breaks"

[18:14] <Ian_> The rest is history
[18:14] <AndyEsser> haha
[18:14] <AndyEsser> am enjoying the fact I'm not having to explain to anyone why I've bought loads of stuff
[18:14] <Ian_> Hi Lunar_Lander, Good day today? No Ublox disasters
[18:15] <Ian_> I like when the XYL misses the postman. That way my Chinese deliveries seem . . . moderate
[18:20] <Ian_> AndyEsser, following up on an earlier thread, this might be of interest, particularly the AVR Fuse Calculator
[18:20] <Lunar_LanderC> hi
[18:20] <Ian_> Atmega328P-PU in particular.
[18:20] <AndyEsser> I saw the AVR Fuse Calculator linked from another page
[18:20] <AndyEsser> sooo helpful :)
[18:21] <Ian_> Whoops - here is the link . . . drum roll . . . http://www.engbedded.com/fusecalc/
[18:21] <AndyEsser> ha
[18:21] <AndyEsser> Yea, that's the one I stumbled on :)
[18:21] <Lunar_LanderC> yea first of all my variable age changed from 0x19 to 0x1A
[18:21] <AndyEsser> err, happy birthday, I believe?

[18:21] <Lunar_LanderC> thanks :)
[18:22] <Ian_> Ditto, Happy Birthday
[18:23] <Lunar_LanderC> :) thank you
[18:23] <Lunar_LanderC> well the most interesting thing for you I suppose is what happened on the system testing
[18:23] <Ian_> ??? nothing too dramatic? :)
[18:24] <Lunar_LanderC> well the first thing was dumb and happenend yesterday
[18:24] <fsphil> happy age++
[18:24] <Ian_> Was that the PSU connected oversight?
[18:24] <Lunar_LanderC> the fan did not switch off after about 3 hours, there was a simple if statement that would switch off the fan after 2700 telemetry lines
[18:24] <Lunar_LanderC> no another thing
[18:24] <Lunar_LanderC> thanks phil
[18:24] <Lunar_LanderC> the fan still ran, and so the final runtime was about 9 h
[18:25] <Lunar_LanderC> there was no function call for that if statement
[18:25] <Lunar_LanderC> :(
[18:25] <Lunar_LanderC> i.e. I didn't include that function to be called in the program
[18:25] <Ian_> Oh no, not another three hour testing session . . . deadline looms
[18:25] <Lunar_LanderC> yea
[18:25] <Lunar_LanderC> well the thing is, we wanted to see how long the batteries would last if the fan shuts off in the end
[18:26] <Lunar_LanderC> for the actual flight I made a construct that shuts it off just before landing
[18:27] <Lunar_LanderC> here comes the thing however
[18:27] <Lunar_LanderC> I put the SD into the reader and into the PC and it didn't open
[18:27] <Lunar_LanderC> checked fdisk -l, it was there

[18:33] <AndyEsser> Ah ok
[18:33] <AndyEsser> Quick q - how quickly typically does the first batch run out?
[18:33] <russss> I'm under-employed at the moment so I'm trying to get as many tickets sold as possible while that's still the case '_
[18:33] <russss> well, this is the earliest we've ever sold tickets and it's the largest initial batch we've ever sold
[18:33] <russss> so lots of variables have changed
[18:33] <fsphil> oh they're on sale already?
[18:34] <russss> Monday, Monday, Monday

[18:44] <fsphil> though everyone else might have the same idea, and no shop will have any tents for sale
[18:44] <mattbrejza> was fine last time
[18:45] <mattbrejza> we were super keen though and up there friday morning
[18:45] <fsphil> will figure something out
[18:46] <AndyEsser> mattbrejza: as I'm the n00b
[18:46] <AndyEsser> can I request everyone wear nametags? :P
[18:46] <fsphil> hah
[18:46] <AndyEsser> I hate going to events/expos and people are like "O you're Andy? I follow you on TWitter!"
[18:46] <fsphil> we all have name tags at ukhas
[18:46] <AndyEsser> and then trying to figure out who they are (I don't know names, just twitter handles)
[18:46] <mattbrejza> there'll be quite a lot of people non-ukhas in habville i think
[18:47] <AndyEsser> there's non-ukas habbers?
[18:47] <AndyEsser> :O
[18:47] <mattbrejza> well people who dont hang around here
[18:47] <fsphil> if there is a spaceville, should we be near it?

[18:49] <fsphil> should we arrange a notam for it? any problems with the location
[18:50] <mattbrejza> not sure how our bbq setup will work next time though
[18:50] <fsphil> I'm sure there will be many quads there
[18:50] <fsphil> could get one to video a launch
[18:51] <mattbrejza> i can see guildford being a no for notams
[18:51] <fsphil> urg
[18:51] <Lunar_LanderC> airport?
[18:52] <mattbrejza> its just too close to london
[18:52] <mattbrejza> and there are many planes that fly over there on their way to gatwick/heathrow
[18:54] <AndyEsser> Dunsfold aerodrome isn't too far
[18:54] <Lunar_LanderC> ah
[18:54] <AndyEsser> I believe it's outside the Heathrow/Gatwick low-fly zones though
[18:54] <AndyEsser> might be worth investigating?
[18:55] <russss> dunsfold isn't in regular use as an airport though
[18:55] <AndyEsser> When I've flown from Redhill Aerodrome before, the 1000-ft alttude restriction ran out pretty quickly
[18:55] <AndyEsser> However, depending on winds the balloon would fly over London + Heathrow/Gatwick
[18:55] <AndyEsser> would be better if it could fly SouthWest
[18:55] <AndyEsser> heh
[18:56] <mattbrejza> hmm actually we tried for farnham and that was a no, so guildford will probably be no too
[18:56] <russss> Farnborough and Blackbushe are the nearest operational airports
[18:56] <AndyEsser> Launch some Picos'?
[18:56] <russss> but yeah, if Farnham is a no then Guildford probably will be
[18:56] <AndyEsser> what are the rules about manned balloons?
[18:57] <mattbrejza> unless you want to launch before 5.30
[18:57] <fsphil> no snakes
[18:57] <mattbrejza> the issue with fleet was heathrow's arrival traffic rather than anything more local
[18:57] <fsphil> if that's not a rule it should be
[18:57] <chris_99> thinking of sending yourself up AndyEsser?
[18:58] <AndyEsser> chris_99: ha no, just noticed there's a fair number of hot air balloon places around Guildford
[18:58] <AndyEsser> fsphil: but Snakes On a Hot Air Balloon doesn't have a good ring to it
[18:59] <mattbrejza> (sunrise is at 5.32 so a 5.30 launch would actually be mostly light)
[18:59] <AndyEsser> mattbrejza: I'd be up for that :)
[19:00] <russss> at least you won't have to go far to launch
[19:00] <AndyEsser> There's an unmanned balloon NOTAM filed for Farnham
[19:00] <mattbrejza> makes a change...
[19:00] <AndyEsser> Ah nevermind...
[19:00] <AndyEsser> 428ft max altitude
[19:00] <daveake> Manchester Space Programme?
[19:01] <daveake> (they launched on a hill, into a tree, last time)
[19:01] <AndyEsser> heh
[19:02] <AndyEsser> I imagine my first launch will go even worse
[19:03] <AndyEsser> Was just trying to work out why there was a NOTAM for a railway
[19:03] <AndyEsser> then realised that RWY means runway... not railway...

[20:36] <SpeedEvil> I looked at maplin a couple of years ago, when I found they had one (1) triac.
[20:37] <Ian_> Maplin mail order is OK, but the stores tend to be a little on the lightweight side of things, having changed a lot over the years.

[20:53] <fsphil> never seen anything else do it
[20:54] <chris_99> what modulation do radiosondes use?
[20:54] <fsphil> gfsk for the uk ones
[20:55] <slee> haven't tried to look for one yet, just decided to mess with them, next set won't be released for 2 more hours
[20:55] <fsphil> 2400 baud

[20:56] <slee> chris_99, http://www.ua.nws.noaa.gov/factsheet.htm
[20:57] <slee> as far as 'where' they launch them...i'm guessing each major airport has a weather station..according to this local weather person

[20:59] <fsphil> it does work in wine (fedora user here)
[20:59] <fsphil> it's a bit ugly though
[21:00] <slee> yea, same people wrote planeplotter/shipplotter..i use both
[21:00] <slee> both work good under wine

[21:49] <slee> he's using sdr# though
[21:50] <fsphil> just noticed on the emfcamp faq, "Things prohibited by our contract: balloons, sky lanterns and the like"
[21:51] <chris_99> cheers slee
[21:51] <AndyEsser> fsphil: awww :(
[21:52] <AndyEsser> I presume they mean like... party balloons
[21:52] <fsphil> russss: would that include say a pico launch? ^
[21:52] Action: AndyEsser hopes
[21:54] <russss> oh that wording actually comes from last year (where there was a HAB launch)
[21:54] <russss> I'll remove it when I get home
[21:54] <craag> aww :(
[21:54] <craag> Wasn't there a no balloons rule last year and we got an exception?
[21:54] <AndyEsser> russss: so that means we could do a HAB launch?
[21:55] <craag> (for the latex met balloon release)
[21:55] <craag> we'd totally be up for doing it again this coming year if we could
[21:55] <AndyEsser> ^
[21:56] <AndyEsser> If I stay on schedule, I'll have done at least one launch by then :)
[21:56] <AndyEsser> be good to see how the professionals do it
[21:57] <Vaizki> well nasa has videos up .. :)
[22:00] <daveake> Yeah, this is how NASA do it .... https://www.youtube.com/watch?v=aMwKVPW5iIw

[22:05] <chris_99> has anyone tracked a uk sonde, i'm looking at http://www.metoffice.gov.uk/learning/science/first-steps/making-observations/upper-air it says they're launched at 2315 UTC
[22:09] <slee> an hour to go
[22:09] <chris_99> you in the UK too?
[22:09] <slee> no, US
[22:09] <chris_99> aha
[22:09] <slee> 2315UTC = 1715CT
[22:09] <russss> yes, if you can get a notam for a launch at EMF, we're not stopping you :)
[22:10] <AndyEsser> \o/
[22:10] <AndyEsser> Do you need a separate NOTAM for each payload/balloon - or can just say "Balloons launched on these dates"?
[22:10] <AndyEsser> and have a single POC
[22:11] <russss> I don't think there's anything in our contract which mentions balloons, but if there is I can almost certainly negotiate an exemption
[22:11] <craag> thanks :)
[22:12] <craag> AndyEsser: Easiest to do a notam per release, although a release can be of more than one balloon.
[22:12] zzqa (~A@c-76-27-48-44.hsd1.ut.comcast.net) joined #highaltitude.
[22:13] <craag> But perhaps a notam per day at least
[22:13] <AndyEsser> craag: yea
[22:13] <AndyEsser> was just wondering if it's worth just arranging a NOTAM per day from 5am to whenever
[22:13] <craag> We'll look at it
[22:13] <AndyEsser> and then people there can just go "Great, I've brought my balloon!"
[22:13] <AndyEsser> :)
[22:13] <craag> See if we can get one at all

[23:16] <AndyEsser> if I cross two, it doesn't join them, just leaves them as distinct tracks

[23:18] <Vaizki> the net tool defines connections, pours etc that should share the same "signal"
[23:18] <Vaizki> the wire tool.. well I honestly haven't gotten around to figuring out what it's good for
[23:19] <Vaizki> I never use it
[23:19] <AndyEsser> haha, fair enough
[23:19] <AndyEsser> ok, so net not wire
[23:20] <Vaizki> and if you are drawing schematic, you need to put junctions in at crossings
[23:20] <Vaizki> although it should make them automatically
[23:20] <Vaizki> been a while since I did any pcb layout..
[23:21] <Vaizki> https://learn.sparkfun.com/tutorials/using-eagle-schematic/wiring-up-the-schematic
[23:21] <Vaizki> some helpful tips there

[23:23] <AndyEsser> Ah ok
[23:23] <AndyEsser> rather than routing it all
[23:24] <AndyEsser> just have the labels MISO/MOSI/etc
