[06:02] <x-f> it should, if your dl-fldigi is online and you have filled at least the "callsign" field in its configuration

[07:49] <SA6BSS-Mike> just startded the radio, been listening on 144,390 so the radio was on that freq at startup and just 15sek after I heard a trnsmission
[07:54] <craag> This is why I reckon sdrs should have 2d navigation on the waterfall
[07:55] <craag> so when you see that momentary signal, you can click below it as it scrolls down the waterfall and decode the IQ as if it was realtime
[07:55] <craag> I don't really understand why no-one's done this yet
[07:56] <fsphil> or grab the waterfall and push it back up
[07:56] <craag> iq data -> ring buffer mapped to waterfall height

[09:13] <sp__> hi all, is anyone around to offer some advice on communicating with a ublox breakout module via an arduino?
[09:13] <sp__> have both a ublox6 and a ublox7 module (both from habsupplies). i followed the habsupplies tutorial (software serial) on both an arduino uno and a nano. in all cases I get stuck with "Reading ACK response: (FAILED!)"
[09:13] <sp__> both GPS modules have worked before, but they've been stored for a few months
[09:14] <UpuWork> hi sp__
[09:14] <UpuWork> are you using software serial to communicate with the module ?
[09:15] iamdanw (uid459@gateway/web/irccloud.com/x-pllhxivzcoziybsk) left irc: Quit: Connection closed for inactivity
[09:17] <sp__> yes, i am following the first part of the tutorial here: http://ava.upuaut.net/store/wiki/doku.php?id=frontpage:levelconvertor
[09:17] <sp__> using software serial on digital pins 4 and 5
[09:17] <UpuWork> Yeah I may remove that its very old code
[09:17] <UpuWork> and not ideal
[09:18] <UpuWork> it doesn't get the expected response back which is why its failing
[09:18] <UpuWork> however try swap RX and TX
[09:18] <UpuWork> also try the first part of this : https://dl.dropboxusercontent.com/u/63720513/PDFS/BO-M6ALC%20Instructions.pdf
[09:18] <UpuWork> which takes software serial out of the equation
[09:19] <UpuWork> The answer I suspect if you're using software serial is to switch to 4800 baud, switch the NMEA messages off, set your settings then turn NMEA back on
[09:19] <UpuWork> back in 15 sorry phone
[09:20] <sp__> yeah, i tried switching tx/rx'
[09:20] <sp__> will look through the pdf, thanks
[09:22] <sp__> are there any LEDs that should light up on the GPD breakout boards? if so, none are!

[13:30] <vincentsan> hello there
[13:33] <vincentsan> I've worked a lot on a first HAB board design and wanted to have your advice.
[13:33] <fsphil> fire away
[13:34] <vincentsan> http://www.up-in-the-air.com/#up2
[13:34] <vincentsan> hello fsphil
[13:44] <mattbrejza> you need to connect aref and agnd to vcc/gnd respectively
[13:45] <mattbrejza> and add a couple caps to the avr's power pins
[13:46] <craag> vincentsan: :)
[13:46] <vincentsan> mattbrejza, ok thanks.
[13:46] <LeoBodnar> If Atmel were to connect them together internally they would have saved billions of lives
[13:46] <vincentsan> craag: your files helped a lot as you can see :)
[13:46] <craag> please don't use autorouter :(
[13:47] <vincentsan> craag, why not ?
[13:47] <mattbrejza> the autorouter has no concept of pretty
[13:47] <craag> you 0.1uF capacitors need to be next to the components
[13:47] <vincentsan> I tried to put them close too. Which one is not ?
[13:47] <craag> oh they mostly are
[13:48] <craag> just autorouter mess confused me :P
[13:48] <vincentsan> Took me 2 days with autorouter so I can't imagine without it...
[13:48] <nats`> something is under the gps antenna
[13:48] <nats`> not a good idea
[13:48] <nats`> remove the trace and the plane running under
[13:49] <craag> vincentsan: Check the ublox datasheet, but I think you should leave V_BCKUP disconnected unless you have a battery there
[13:49] <vincentsan> nats, ok no plane or gnd plane ?
[13:49] <craag> or maybe even connected to grond
[13:49] <craag> vincentsan: Check the gps antenna datasheet
[13:50] <craag> for how you should place the ground planes around it
[13:50] <mattbrejza> your programming header and the other three pin one might be too close
[13:50] <craag> Also I think you might struggle to connect an ICSP device with another header that close
[13:50] <mattbrejza> heh
[13:50] <craag> argh too slow
[13:51] <vincentsan> I was afraid so
[13:51] <vincentsan> so my board will need to be bigger
[13:51] <vincentsan> craag, V_BCKP seems to be connected to 3V3 in CRAAG2
[13:52] <craag> vincentsan: Yep, I think I may have been wrong - you should check!
[13:52] <vincentsan> ok, I will
[13:52] <nats`> vincentsan where is the rfm antenna output ?
[13:52] <nats`> and to be honnest the autorouter didn't screw this board too much !
[13:53] <vincentsan> nats', on the bottom plane bottom right
[13:53] <craag> Yeah to be fair it's the best autorouted board I've ever seen
[13:53] <vincentsan> nats', I run the Autorouter thousand times before getting to this...
[13:53] <nats`> yep but where is it ?
[13:53] <nats`> I don't see the ouput
[13:53] <nats`> because antenna needs to be "free"
[13:54] <nats`> no plane too close or on the upper layer
[13:54] <vincentsan> my plan was to solder a guitar wire on the SMD pad as RFM antenna
[13:54] <fsphil> LeoBodnar: they are connected internally in some of them iirc
[13:55] <nats`> vincentsan the problem is all the pad are surrounded by gnd plane
[13:56] <nats`> on the pad for antenna remove the gnd plane going to the border
[13:56] <nats`> :)
[13:57] <vincentsan> nats', if you look at the picture with no ground plane you can see that the antenna pad is directly to the border (even after added GND plane). Or I did not understand your point

[13:58] <mattbrejza> you dont need the pullup resistor on reset on the avr btw

[13:59] <vincentsan> mattbrejza, even if connected to the PGR SPI ?
[13:59] <craag> fsphil: james even wires Vcc *through* the avr to the rfm22 on his stripboard ukhasnet nodes :P
[14:00] <craag> vincentsan: Yep, not needed.
[14:00] <craag> AVR has one internally
[14:00] <vincentsan> GREAT !!! One place won
[14:01] <vincentsan> What about the 0.1uF mattbrejza said I was missing on the AVR. Most boards do not seem to have them
[14:01] <craag> btw DO put a pullup on the NSS line
[14:01] <craag> it'll switch off the RFM while you're using the ICSP

[14:01] <mattbrejza> isnt that internally pulled up too?
[14:01] <mattbrejza> oh nss
[14:01] <mattbrejza> ignore me
[14:02] <craag> nope it isn't - I have a couple of missing hours to prove it :)
[14:02] BrainDamage (~BrainDama@dynamic-adsl-94-36-226-146.clienti.tiscali.it) joined #highaltitude.
[14:02] <craag> vincentsan: More 0.1 's the better
[14:02] <mattbrejza> for the avr trackers i did i put a resistor inline with MISO instead
[14:02] <vincentsan> craag, hum ok
[14:03] <craag> vincentsan: Even if you put the footprint, you don't have to populate it
[14:03] <craag> but means if you have issues, you can easily add more
[14:03] <vincentsan> craag, yep my concern it the board size but for a first one I can increase it a little bit :)
[14:04] <craag> I would recommend spacing everything out a bit for a first ever board
[14:04] <craag> gives more room to rework any mistakes
[14:04] <vincentsan> craag, pull up on NSS like you did in https://raw.githubusercontent.com/philcrump/UKHASnet-avr-sensor/master/V2/Schematic%20V2.png ?
[14:04] <craag> although the schematic is looking sound to me, well done!
[14:04] <craag> exactly.
[14:04] <craag> CRAAG2 was my first ever pcb
[14:05] <craag> didn't have much peer review either
[14:05] <vincentsan> ok, sound great. Any missing components apart from the 0.1uF ? So I can order TODAY !
[14:05] <nats`> where do you order ?
[14:05] <craag> did you check about V_BCKUP?
[14:06] <nats`> I just advice that you bought a "book" of capacitor and resistor on ebay
[14:06] <nats`> for the size you love
[14:06] <mattbrejza> china is probably in bed atm so you have a while still to get it ready without delaying it
[14:06] <vincentsan> Not yet, but I will rework the board and check V_BCKUP
[14:06] <vincentsan> exactly
[14:06] <craag> Ok, and move that track away from the gps antenna
[14:06] <craag> try to have jsut ground plane under any antenna track
[14:07] <craag> (not under the antenna itself though!)
[14:07] <vincentsan> nats', digikey ? or mouser (but they don't have JST plug)
[14:07] <vincentsan> craag, yep I'll work on it today. Should have a good version tomorrow. I'll post it here
[14:07] <nats`> I prefere mouser but take time for the resistor and capacitor book on ebay
[14:07] <mattbrejza> clean up the silk before you send it off too
[14:08] <nats`> it'll save you night of fear and pain :D
[14:08] <craag> vincentsan: :) and well done, looking good!
[14:08] <vincentsan> mattbrejza, yes I did not manage to do that apart from renaming the components
[14:08] <mattbrejza> use the smash button so you can move labels around
[14:08] <vincentsan> I have to get used to Eagle
[14:09] <mattbrejza> i find text size of 40 tends to work well
[14:09] <nats`> vincentsan I would advice against that
[14:09] <nats`> since you're not used to any cad take a real one :p
[14:09] <nats`> with dynamic drc for example :p

[14:10] <vincentsan> Also, I plan to do reflow soldering. Is T-962 Reflow Oven OK to start with ?
[14:12] <nats`> nop it's a crap
[14:12] <nats`> I have one and I massively modified it
[14:12] <vincentsan> craag, last question. Can the NSS pull up be 1MOhm ? So I just order 1Ms
[14:12] <vincentsan> nats', so what should I go for ?
[14:12] <mattbrejza> http://www.ebay.co.uk/itm/321125170580 vincentsan
[14:13] <vincentsan> mattbrejza, your two links are blocked by ebay

[14:13] <nats`> yep

[14:15] <mattbrejza> im a tweezer iron guy
[14:15] <nats`> :D
[14:15] <vincentsan> nats', yep would be great !
[14:15] <mattbrejza> i wouldnt bother reflowing something this small, its probably more effort than using a decent iron
[14:16] <nats`> agree mattbrejza
[14:16] <vincentsan> I don't feel soldering the Atmega...
[14:16] <nats`> it's easy :)
[14:17] <nats`> really it's easier than masteering a good reflow :)
[14:17] <nats`> take desolder bread
[14:17] <vincentsan> I see, you'll teach me then !
[14:17] <nats`> you flood the pin
[14:17] <nats`> and you "suck" :D
[14:17] <nats`> yep no problem for that :)
[14:17] <vincentsan> I've seen some tutorial of this sucking technique on sparkfun
[14:17] <mattbrejza> if youre flooding the pins to solder them you probably need a better iron ;)
[14:18] <vincentsan> For now, I have that : http://www.amazon.fr/gp/product/B0018S7G6E/ref=oh_aui_detailpage_o03_s00?ie=UTF8&psc=1
[14:18] <vincentsan> Maybe this is the problem...
[14:19] <mattbrejza> also fine solder
[14:19] <mattbrejza> and flux helps
[14:19] <vincentsan> mattbrejza, flux ?
[14:20] <mattbrejza> it cleans the area and just makes everything go nicely
[14:21] <vincentsan> ok, I'll into all these stuff. Should come back tomorrow with an updated design !
[14:21] <vincentsan> Thanks everybody for your kind advices

[20:03] <vincentsan> mfa298 (/mattbrejza), after checking the avr-hardware-design-considerations-application-note, decoupling 1uF is recommended for all VCC/GND pairs but this is not what I see in most circuits where most decoupling cap are omitted... Will keep with the safer approach for this first board. Thks
[20:05] <craag> vincentsan: You can often get away with less, but it's a good idea to at least put the space on the board in case you do need them.
[20:05] <craag> Also given how cheap they are...
[20:07] <vincentsan> craag, agreed. I just bought 100 for a ¬... About the resistor with the SS pin, can I use a 1M Ohm ?
[20:08] <craag> The stat to check there is how much current the NSS pin on the RFM will draw
[20:08] marshall_law (~marshall_@24-178-212-229.static.ftwo.tx.charter.com) joined #highaltitude.
[20:09] <craag> then you can work out what the voltage will be over the 1M ohm
[20:09] <craag> if it's larger than 1V or so, then no.
[20:09] <mfa298> decoupling is recommended on most digital IC's - modules (gps breakout, ntx2b etc) often have them so may not be required for that but if you were putting the ublox module and some rf chip direct on the pcb they probably want decoupling caps as well. as craag said they're cheap enough and you can always choose not to populate the pads if you dont want to
[20:09] <fsphil> decouple everything
[20:09] <fsphil> all the time
[20:09] <fsphil> learned this lesson a few times
[20:10] <myself> vincentsan: When you see decoupling caps omitted, are those circuits coming from amateurs or pros? Are they hobby circuits, or stuff where reliability is important? I ask because omitting decoupling caps (and having trouble because of it) is the single most common defect I see in hobbyist circuits, which are *all over the net* thanks to arduino, which conveniently omits them in most of their example circuits, too...
[20:11] <vincentsan> Ok, I am now fan of decoupling caps :)
[20:11] <bertrik> the most common fixes on hardware prototypes at the place I work, is usually moar capacitors (and a few wires and lifted pins) :)
[20:12] <vincentsan> craag, thanks for the resistor explanation. I will check this tomorrow with the GPS backup

[20:16] <Lunar_Lander> since I saw them in a circuit
[20:16] <Lunar_Lander> :P
[20:18] <craag> I've started adding 1uf // 100nf pairs
[20:19] <fsphil> I've seen some circuits use two different values
[20:19] <fsphil> any good reason to?
[20:20] <craag> 1uf tend to have more inductance
[20:21] <craag> so 0.1 is better for rf noise
[20:21] <craag> 1uf for sub-rf
[20:21] <craag> then electrolytic for ~audio freq / reservoir
[20:22] <craag> That's my thinking
[20:22] <craag> But it's more that I was always told to put 0.1 everywhere, yet a lot of ldo datasheets ask for 1uf
[20:22] <craag> so both :)

[20:29] <craag> I did once come across a board where too much decoupling had caused a major problem
[20:29] <craag> but that was 1000s of uF of ceramics
[20:29] <craag> per board (x6 in a unit)
[20:29] <fsphil> initial power surge?
[20:29] <myself> regulator stability
[20:30] <craag> nope, they had very carefully studied startup ramps, little more subtle
[20:30] <craag> these boards pulled 20A at 12V each
[20:30] <mfa298> I think I remember seeing a document (probably posted on here) that suggested the differeing values were important for higher speed digital and I think part of the reason given was down to the ESR (although that could be a similar argument to differeing internal inductance)

[20:31] <craag> And there was a button in the remote management software that allowed you to switch off any number of boards, instantly.
[20:31] <myself> a linear regulator is a special case of amplifier, configured for maximum negative feedback. But with enough C to delay the response, it looks like phase-shift, and that feedback becomes positive.. :) http://www.ti.com/lit/an/snva167a/snva167a.pdf
