[08:48] <samme> Hey, I was unable to find connection for Lithium battery to Arduino board... found this https://www.sparkfun.com/products/10255 which can be connected to Vin or barrel jack. Any other suggestions?
[08:49] gtfhercules (~gtfhercul@c-24-5-194-136.hsd1.ca.comcast.net) left irc: Read error: Connection reset by peer
[08:54] <daveake> That's for LiPo - you want to use Lithium primary cells
[08:55] <daveake> You just connect a few of those (Lithium Energizer) in series and then to the Vin on the Arduino; how many depends on the Arduino
[08:56] Vaizki (vaizki@arkki.vaizki.fi) left irc: Quit: ZNC - http://znc.in

[08:57] Vaizki (vaizki@arkki.vaizki.fi) joined #highaltitude.
[08:58] <samme> current handling is good with lithium ion and recharging capability.
[08:59] <daveake> Temperature
[08:59] <daveake> You don't need high current handling, and the ability to recharge isn't important unless you're planning on a long-term flight (which seems unlikely if you're using an Arduino)
[09:00] <samme> oppppsy, -20 for lithium ion
[09:00] <samme> got your point (Y)
[09:00] <daveake> They're probably fine if you have a camera in there (and most cameras use them anyway)
[09:00] <Vaizki> primary lithiums behave really really well in the cold if not taxed with high current
[09:01] RocketBoy (~steverand@ joined #highaltitude.
[09:02] <mfa298> the other benefit of usign the lithium engergizers, is if you use new ones straight otu the pack you can be very confident they'll have the claimed capacity, rechargable cells you have to hope you remembeded to charge them the last night, and you've not used it so much the capacity hasn't dropped off too much
[09:02] <samme> if I am not mistaken, someone over here told me Energizer cells are better than Duracell?
[09:07] <samme> AA or AAA makes difference?
[09:07] <samme> besides size
[09:07] <craag> samme: "Energizer Ultimate Lithium" are the most available brand of the primary lithium cells
[09:07] <mfa298> AA will have more capacity
[09:07] <craag> either AA/AAA is fine, choose the capacity you want
[09:07] RocketBoy (steverand@ left #highaltitude.

[09:10] <adamgreig> Just to dissent a but, lipos work fine in most hab applications too, even as they get cold (charging in cold is a bigger problem than discharging in cold)
[09:10] <adamgreig> bit*
[09:11] <adamgreig> lithium primaries are great, sure, but expensive and single use and probably overkill for a simple hab flight in an insulated payload box
[09:13] <fsphil> post-flight lithium primaries are great for all the remote controls around the house
[09:13] <samme> understood
[09:15] <fsphil> has anyone flown a single lipo more than a few times?
[09:15] <craag> I've got one in my wireless mouse - feels light and weird :)
[09:15] <fsphil> hah

[09:23] <Geoff-G8DHE_> Hummmmm....Facebook is suddenly shoing me adverts for lithium batteries ??
[09:24] <mfa298> I'd argue for the occasional flier lithium primaries are probably the best bet, low risk and not that expensive in the scheme of things, for regular fliers lipo might be better, but then you probably have enoguh batteries and way of testing to be confident they're still good for a flight

[11:09] <pa3weg> fsPhil: Have you been asked to speak as well?
[11:09] <fsPhil> yeah, will be taking briefly about ssdv
[11:09] Nick change: fsPhil -> fsphil
[11:09] Nick change: pa3weg -> PA3WEG
[11:10] <PA3WEG> OK, I knew we were talking to you about that with the FUNcube team
[11:10] <PA3WEG> (my suggestion together with graham G3VZV)
[11:10] <PA3WEG> but a talk is also really appreciated
[11:11] <PA3WEG> excellent!
[11:11] <fsphil> I've never been to an event like it, should be interesting
[11:12] <PA3WEG> well, you´ll find Phil Crump in the back and myself, for the BATC, and Jules
[11:12] <PA3WEG> dont know if there will be more HABbers
[11:13] <PA3WEG> right...back to documenting modulation schemes...AFK
[11:14] <gonzo_> are you over for the week phil?
[11:15] <fsphil> just the weekend
[11:15] <fsphil> then back again for emf
[11:15] <gonzo_> that's a lot of flights
[11:15] <fsphil> yeah. don't mind though
[11:15] <edmoore> they're not long flights at least
[11:16] <fsphil> yeah
[11:16] <PA3WEG> craag: You will be doing the video?
[11:16] <fsphil> I'd looked at getting a bus but it's an overnight trip and not much difference in price
[11:17] <craag> PA3WEG: I think I've wrestled responsiblity of the audio on this one :)
[11:18] <fsphil> I can bring an 869mhz mic if you want :)
[11:18] <PA3WEG> sure, I will do video then, or we will relay resonsibilities (see PM)
[11:18] <PA3WEG> *responsibilities
[11:19] <gonzo_> and trun off your lora in the handbaggage
[11:21] <craag> fsphil: I've got a couple of proper sennheiser units booked out from our student's union :)
[11:21] <PA3WEG> excellent. I will also be bringing my RODE wireless lavlink
[11:22] <PA3WEG> and maybe my camera, will check with Noel about that
[11:22] <fsphil> nice
[11:22] <PA3WEG> got the proper SDI converter now as well, just need to know the framerate and resolution
[11:22] <craag> Not stretching to the digital desk this time though :(
[11:22] <PA3WEG> the ATEM does not do sample rate conversion
[11:23] <craag> yeah we run it at 1080i <something>
[11:23] <craag> </veryhelpful>
[11:23] <craag> talk to frank/noel
[11:23] <PA3WEG> will do
[11:23] <PA3WEG> only have Noel on skype, I´m sure we can figure it out
[11:23] <PA3WEG> it has to fit in the plane as well ;)
[11:24] <edmoore> in nice and expensive looking peli cases?
[11:25] <edmoore> craag: do you know if one can fit a ds1054 in a 1510 peli?
[11:26] <craag> I do not know, yet
[11:27] <PA3WEG> got the camera in explorer case, peli too big ;)
[11:28] <PA3WEG> I found the perfect size explorer for that, and peli does not have a deep but small model.
[11:30] <PA3WEG> right....I was going back to work
[11:30] <PA3WEG> the trouble with working from home days is distractions
[11:30] <gonzo_> yep, work gets in the way

[13:58] <daveake> Glad it works :)
[13:59] <daveake> I think either the calling channel, or just using a wider bandwidth, is the best for telemetry
[13:59] <daveake> This 5kHz variation is a pita otherwise
[13:59] <Geoff-G8DHE_> I like the calling channel ide as I leave the Pi running on that now so it just starts working!
[13:59] <daveake> sure
[14:00] <swaledale> has the calling channel not got much of a following then? I thought that would have become more popular now. The idea is great.

[14:03] <swaledale> I offered to lend a hand if wanted 'free' assistance but didnt get a reply
[14:03] <daveake> However, not sure it's a good use .. 5 flights all trying to get receiver's attention :)
[14:04] <daveake> OK I'll remind him
[14:04] <daveake> 30 attendees this year so help would be good
[14:04] <edmoore> jakeio: many chips and modules have multiple gnd pins usually
[14:05] <swaledale> yeah thats a good number. I can obviously pass on my 'sea landing' experience of last year :)
[14:05] <edmoore> it's normal and important for a good low impedance, low inductance path to ground for high speed signals
[14:05] YO9GJX (~YO9GJX@ joined #highaltitude.
[14:05] <jakeio> So, edmoore, should I be connecting up all 3 when linking to the pi?
[14:06] <gonzo_> I suspect at leas one is nex to the ant pin
[14:06] <edmoore> yes
[14:06] <gonzo_> for low impeadnece for thr RF
[14:06] <Geoff-G8DHE_> Yes but very few times when multipile flights take place!
[14:06] <jakeio> OK, many thanks.
[14:07] <swaledale> i think using it for when there are multiple flights, e.g. skycademy, its use isnt appropriate, but when everyone spreads their wings as it were, it could be useful
[14:07] <edmoore> with a lot of electronics you might get away with not doing it
[14:07] <edmoore> but usually it's worth doing it right unless there's a good reason to not
[14:07] RocketBoy (~steverand@ joined #highaltitude.
[14:08] <daveake> agreed swaledale
[14:09] <daveake> Also, for skycademy, I want to discuss having everyone on the same frequency, time-sharing.
[14:09] <PA3WEG> I hear the RTTY on 350, but there is massive QRM around
[14:10] <edmoore> with gps-loss clock failover :)
[14:10] <PA3WEG> 405 is next to unusable
[14:10] <daveake> yes
[14:10] <swaledale> right, guess that could increase the number of people able to track multiple payloads
[14:10] <daveake> also useful on startup when you're waiting for a lock
[14:11] <pjm> daveake, i will shortly move my dual band LoRA box up to a super site which should cover most of south UK
[14:11] <daveake> yes plus the teams can help each other
[14:12] <edmoore> does the pi have an rtc?
[14:12] <G3WDI> lora what MODE ?
[14:12] <pjm> edmoore, no but to add is pence
[14:12] <swaledale> also allows more to go chasing rather than lots of 'short straw' for who stays behind, as less would be needed in that tracking team at base

[14:15] <edmoore> that'd be cool
[14:15] <edmoore> first to lock shares
[14:15] <edmoore> a neat idea
[14:15] <daveake> yeah don't want any arguments - payload 1 syncs to payload 2 which syncs to 1 ...
[14:15] <edmoore> ntp over lora
[14:15] <daveake> ha
[14:15] <swaledale> lol ntp
[14:15] <edmoore> haha only serious?
[14:17] <swaledale> guess it has to stay simple enough for new folk to grasp too for skycademy
[14:17] <daveake> Well they wouldn't be doing the coding
[14:17] <daveake> All they need to do is set a slot for each payload
[14:17] <fsphil> but that's the fun bit
[14:17] <edmoore> but simple to explain is good too
[14:17] <swaledale> yes thats true
[14:17] <edmoore> as it's fo teachin
[14:18] <daveake> could do the repeating thing too
[14:18] <daveake> might make chasing too easy for them, mind :)
[14:18] <swaledale> i quite like the idea, repeating too, just looking back at the google group over the past year's worth of 'its not working' queries :)
[14:19] <edmoore> are they related to repetition or lack of it?
[14:19] <edmoore> what do you mean swaledale ?
[14:19] <daveake> related to not being able to turn dials on radios
[14:20] <swaledale> edmoore: some of the more simple stuff being overlooked, just down to a very broad spread of ability, not a bad thing just an observation
[14:20] <edmoore> i get that bit, i was wondering how the repetion thing came into it
[14:20] <edmoore> but not to worry

[14:22] <daveake> I think the repeating would be a bd idea for this ... the course needs to show what it's like to launch and chase, and when they do that themselves later they won't conveniently have an airborne repeater to locate their payload for them
[14:23] <daveake> Fun as it is (and it was probably my favourite flight when I did it) it's not repreentative
[14:25] <swaledale> is the plan to stick with pi or try out pi zero? guessing the boards arent ready yet
[14:25] <daveake> The fab messed up on the zero so we're waiting on them doing a re-run
[14:25] <fsphil> there's a few missing packets, odd considering the number of receivers
[14:26] samme (8258f052@gateway/web/freenode/ip. joined #highaltitude.
[14:26] <daveake> The fault is easily fixed with a blob of solder and I'll probably fly this blobbed one soon
[14:26] <swaledale> ah thats good that its not too major then
[14:27] <swaledale> i guess using a zero would introduce soldering skills to the course as well! :)
[14:29] <daveake> Given what a couple of customers have done when trying to plug a board onto a regular Pi, I shudder to thing what they'd manage with a soldering iron
[14:29] <daveake> think
[14:30] <swaledale> absolutely!
[14:30] <edmoore> aradilte instead of solder
[14:31] <swaledale> school teachers are more likely to use plasticine!

[19:46] <___BEN___> uputronics sell the uBLOX MAX-M8Q and uBLOX MAX-M8C for ~£20. Are these superior GPS modules in any way from the far cheaper Ublox NEO-6M, which seams to be more than half the price. Has anyone used the cheep ebay GPS modules? Are they any good for High Altitude Ballooning?
[19:47] <___BEN___> Or should I bite the bullet and get the uputronics ones.
[19:48] <___BEN___> 10
[19:49] <Geoff-G8DHE_> I seem to recall someone bought some cheaper ones and they all had the same serial number #000000

[21:48] <michal_f> is it possible to make LoRa chips to do RTTY ?
[21:48] <michal_f> I'm thinking of adding LoRa to my tracker and replacing NTX would be best option for me
[21:49] <Vaizki> well the SX1272 does do FSK.. and RTTY is basically 2FSK
[21:49] <pjm> michal_f, there was a dual mode flight today in UK that was tty / lora
[21:49] <michal_f> I was thinking of getting one from upu store...
[21:49] <Vaizki> I have not tried RTTY with them myself
[21:50] <michal_f> pjm: this was from the same chip? or was it LoRa + radiometrix perhaps ?
[21:51] <craag> michal_f: You can do it
[21:51] <craag> there's several ways
[21:51] <craag> (with rfm98)
[21:51] <michal_f> craag, any pointers are very welcome !
[21:51] <pjm> michal_f, as far as i know it was an rfm 434MHz module
[21:51] <craag> easiest is to, as with rfm22, just waggle the programmed frequency when in carrier tx
[21:51] <pjm> tty followed by lora
[21:52] <craag> there is a note about it in the DS
[21:53] <michal_f> so it's possible. this is good news
[21:53] <pjm> https://groups.google.com/forum/#!topic/ukhas/g5sW0GsSgqU this is the launch notification
[21:53] <pjm> u should contact the dude to ask how he did it
[21:53] <pjm> the lora stuff was generally superior compared to the tty
[21:54] <pjm> and was error free even with signals barely visible in fft
[21:54] <Vaizki> hmmh it seems that the built-in FSK modulator does not do slower than 1200baud
[21:54] <Vaizki> so yea I guess just change the carrier freq
[21:54] <gonzo__p> lots of fec
[21:55] <michal_f> Steve Randall == RocketBoy ?
[21:55] <craag> michal_f: See p77 in the datasheet
[21:55] <Vaizki> michal_f: check page 82 of http://www.semtech.com/images/datasheet/sx1272.pdf
[21:55] <craag> the 'Note' in section 5.3.3
[21:56] <craag> " A change in the center frequency will only be taken into account when the
[21:56] <michal_f> looking up now ...
[21:56] <craag> least significant byte FrfLsb in RegFrfLsb is written. This allows the potential for user generation of m-ary FSK at
[21:56] <Vaizki> well same note :)
[21:56] <craag> very low bit rates."
[21:56] <Vaizki> my page number was different
[21:56] <craag> rfm datasheet
[21:56] <Vaizki> ah right
[21:56] <pjm> todays stuff was 75baud / lora
[21:56] <Vaizki> same note is in the semtech chipset ds
[21:56] <craag> half of rfm datasheet is copypasta, so no surprise there :)
[21:57] <SM0ULC-Reb> pjm: unlurking i see :)
[21:59] <Vaizki> the DS also says 20us to hop the carrier between the RTTY frequencies.. that's quite speedy
[22:01] <Vaizki> well time to sleep.. 1am and wakeup at 6am :)
[22:01] <michal_f> that would give 25000 baud theoreticaly ?
[22:02] <Vaizki> hehe

[22:02] <michal_f> g'night Vaizki
[22:02] <Vaizki> well you can stay there as long as you want :)
[22:02] <Vaizki> that's just the transition time between frequencies. it has to be very fast compared to the symbol length
[22:03] <michal_f> ok. I get it...

[22:40] <RocketBoy> michal_f: Im here now
[22:41] <michal_f> hi RocketBoy... others say you launched a payload with both lora and rtty
[22:42] <michal_f> did you do RTTY with LoRa chip or with smth else ?
[22:43] <RocketBoy> both with the sx1276 chip
[22:43] <RocketBoy> itts relativly easy
[22:43] <michal_f> what I try to do is replace NTX2b with RFM98W
[22:44] <michal_f> do you have any tips, code, anything that could help me get started ?
[22:44] <michal_f> (I haven't even ordered the modules yet :)
[22:45] <RocketBoy> the RFM98W is just a SX1278 chip (plus discretes) on a board
[22:46] <RocketBoy> dooing RTTY is easy IIRC
[22:46] <michal_f> did you control it with arduino, rasPI or something else ?
[22:48] <RocketBoy> a PIC chip - well actually Im using a Microchip RN2483 whic is a 18LF46K22 and a SX1276 in a single module
[22:48] <RocketBoy> you can set the SX1276 up to be modulated by a single GPIO pin
[22:49] <RocketBoy> 0 and 1 on the pin just shift the frequency
[22:50] <michal_f> ok, thanks... I'll wait for my boards and return with more specific questions :)
[22:52] <RocketBoy> OK - NP
[22:57] <___BEN___> Upu, Thankyou for the info
