[04:13] <nigelvh> Anyone on presently who's used any of the SI44XX chips?
[04:17] <arko> yes
[04:17] <arko> Si446x
[04:17] <arko> and Si406x
[04:18] <arko> wassup nigelvh
[04:18] <nigelvh> I've got my new board with the 4464. Seems to work ok, except every so often it seems to just hang and stops responding to commands.
[04:18] <nigelvh> I end up resetting it and it works ok, but does it again a bit later.
[04:18] <arko> ...
[04:18] <arko> weird
[04:18] <nigelvh> Have you seen that behavior?
[04:18] <arko> hmm
[04:18] <arko> can't say i've seen that
[04:19] <arko> driving it via a gpio?
[04:19] <nigelvh> Driving what via a GPIO?
[04:19] <arko> the fsk
[04:19] <nigelvh> No modulation presently.
[04:19] <arko> oh
[04:20] <arko> just keying up?
[04:20] <nigelvh> Current code just enables a carrier for about five seconds, then turns it off for about five seconds. Repeat.
[04:20] <arko> ah
[04:20] <nigelvh> Every say 4th-7th cycle it seems to hang and requires a reset. Sometimes shorter, sometimes longer.
[04:21] <arko> btw, the serial bus on these things is very slow
[04:21] <arko> no idea why
[04:21] <arko> but i leave plenty of time between commands
[04:21] <nigelvh> Yeah, I've divided the SPI clock by /128.
[04:21] <nigelvh> Should slow down the atmega talking to it a bit.
[04:21] <arko> probably a good idea
[04:22] <nigelvh> And I wait until it bring the IRQ pin up indicating it's ready for new commands.
[04:22] <arko> im running it at 1mH
[04:22] <arko> err
[04:22] <arko> 1MHz
[04:22] <arko> works fine
[04:23] <nigelvh> Hmm
[04:25] <nigelvh> Interesting. Like I said, it comes on fine and generates RF. Just seems to hang randomly.
[04:25] <arko> hmm
[04:26] <arko> vOv
[04:26] <arko> no idea
[04:26] <arko> haha
[04:26] <arko> sorry
[04:26] <nigelvh> Hmm. I'll have to keep fiddling.
[04:27] <nigelvh> I had a test board with a 4464 on it, and though I wasn't doing RF, I was communicating TONS enabling and disabling the GPIOs, and it worked fine.
[04:27] <nigelvh> Perhaps that should be my next test, not enable RF.
[04:28] <nigelvh> Just fiddle GPIOs a ton.
[04:28] <nigelvh> See if it still freezes.
[04:31] <nigelvh> Alright, code updated to blink leds a lot.
[04:33] <nigelvh> Hmm, lots of blinks and it would have frozen by now.
[04:35] <nigelvh> One by one re-enabling the tx commands.
[04:44] <nigelvh> Interesting, so setting the output divider, modulation type, pa power level, the frequency, and tuning the tx doesn't freeze it, but actually switching to the TX state does.
[04:47] <nigelvh> And if I don't actually send the TX command, but do send the return to ready state command it doesn't freeze either.
[04:47] <nigelvh> Just the enter TX state command.

[05:11] <KT5TK> Maybe the RF radiates into your data lines?
[05:12] <nigelvh> Maybe...
[05:12] <KT5TK> Try to block it with a 18 pF cap to ground
[05:13] <nigelvh> I assume you're suggesting on the MOSI pin?
[05:13] <KT5TK> yes, but possibly also clock
[05:13] <KT5TK> Try one at a time
[05:14] <nigelvh> K. I'll try those tomorrow. Time to head towards bed presently.
[05:14] <nigelvh> Thanks for the input.
[05:14] <KT5TK> close as possible to the Si4464
[05:14] <nigelvh> Yeah
[05:15] <nigelvh> Anyway, I'll let you know where I end up tomorrow.
[05:15] <nigelvh> Have a good evening.
[05:16] <KT5TK> NP good luck!

[07:59] <Lunar_LanderU> first question of the day, concerning Upu's shop, he writes "Eagle schematic is in the default Eagle Libraries. The part is under con-coax.lbr and is called BU-SMA-A " for the SMA connector, I can only find BU-SMA-G, -V and -H
[07:59] <Lunar_LanderU> what of those is a 90° connector?

[08:42] <ibanezmatt13> Hey UpuWork, I had a go at the TPS61201 in Eagle last night. I understood how you did it and I see now how it relates to the example layout in the schematic. However, I couldn't get the polygon tool to work properly. When I was hitting ratsnest, the polygon was just a blob in between where I wanted it connected.
[08:42] <UpuWork> right click -> properties -> uncheck thermals
[08:42] <ibanezmatt13> I did that too
[08:42] <KiwiDean1> Upu, that's what shots from down under will look like :-)

[08:48] <KiwiDean1> The North Island (don't you love our creative names!) has the Desert Road running through the middle, but it's not really a desert, just a relatively unpopulated barren area that's pretty cold and bleak in winter.

[09:05] <KiwiDean1> Lunar, like the pic :-) Yep, Christchurch, middle of the South Island. New to HAB, looking at doing my first launch in a few months time.
[09:06] <HixWork> I'm gutted that my plan to spend a few days cycle camping on Uist got scuppered by unplanned work changes. I'm guessing that with the weather as it was, there was little on earth to rival the place. Not such a great location for HAB though :)
[09:07] <ibanezmatt13> UpuWork: I'm attempting those polygons again. So I do the polygons on the top layer I think. What shall I set the width to?

[09:12] <HixWork> ok
[09:12] <eroomde> and even if i was i don't know
[09:12] <eroomde> depends on other stuff
[09:13] <HixWork> I'm guessing if there is high enough activity, it's got to be a pretty awesome Auroura spotting location too. as a night-time bonus
[09:13] <eroomde> i'd be inclined to go further north
[09:13] <eroomde> get inside the arctic circle
[09:14] <HixWork> that would make my cycle-camping plan a little more of an expedition though :)

[09:25] <daveake> Yes the non space one
[09:25] <Babs> as in it didn't have any engines
[09:25] <KiwiDean1> Thanks Lunar, apart from the usual met service weathersonds, there's been at least two other launches blogged about on the web. One was local and the guy started from scratch without much help from outside sources like UKHAS or HABHub going by his write up, the other looked a lot more professional.
[09:25] <eroomde> i did like the engine
[09:25] <daveake> Yup - a glider

[09:25] <eroomde> morning jcoxon
[09:26] <Babs> I had a nice chat with a very knowledgeable lady there (super knowledgeable actually) on the engine gimbals

[09:39] <ibanezmatt13> UpuWork: I'm seem to be having an issue with the polygon that connects one side of the inductor to the L pin on the step up. Even though I've unchecked thermals and the polygon is clearly there, hitting ratsnest leaves a gap between the step up and the inductor. Is it something to do with naming the polygon or something? I have polygon width set to 0.
[09:41] <eroomde> Ugi, THANKS V MUCH
[09:41] <eroomde> whoops
[09:41] <eroomde> c-stoff kicking in
[09:42] <eroomde> pleased they clarified about virgin
[09:42] <Babs> eroomde - all of this talk of "aircraft like" reusability and turnaround
[09:42] <eroomde> i'm fed up with 'oh so is this richard branson!?' when i explain what i do to people
[09:43] <eroomde> his stuff is a fairground ride
[09:43] <Babs> is that the press jumping to conclusions or is it something you guys push
[09:43] <Babs> or is this not for this page?
[09:43] <eroomde> no, that's the whole point of it
[09:43] <eroomde> fast turnaround
[09:43] <Babs> i can see that, but doesn't it create a bunch of pressure
[09:44] <eroomde> well, i suspect the intial market probably won't require 48-hour turnarounds
[09:44] <Babs> for you guys
[09:44] <Babs> I think the person who will be most annoyed by the Branson reference is Bert Rutan
[09:44] <eroomde> it doesn't really create pressure, any more than the requirement creates pressure for boeing
[09:44] <HixWork> just wait 'till Michael O'Leary gets involved
[09:45] <eroomde> it is just going to be designed to not have to be dissassembled and inspected between flights, much like an airliner

[09:54] <eroomde> i can recommend places and things and guides

[09:54] <eroomde> but basically, go in jan/feb, it's the solar maximum and the weather is better than nov/dec
[09:54] <eroomde> jcoxon, we could do a trans-a to hix
[09:55] <HixWork> trans-a?

[10:06] <Babs> they discontinued the direct flight (did my engagement thing last year, saw naff all Northern Lights"

[10:07] <Babs> or at least that was what it was like last December
[10:07] <eroomde> yeah, change in oslo presumably
[10:07] <eroomde> no huge biggie

[11:54] <HixWork> Steve_2E0VET this seems to be a cheaper option though http://goo.gl/lG53xc
[11:54] <Steve_2E0VET> Am I correct in thinking I can upload and run sketches while I have my GPS connected to 0 and 1
[11:55] <HixWork> if using ICSP yes, otherwise no
[11:55] <Steve_2E0VET> What's iCal oh and the actual500 is £15 on ebay
[11:55] <HixWork> I also found this on friday, http://www.bitsbox.co.uk/data/modules/USBasp1.pdf its £5.75 so could be useful. Not sure on it though

[12:01] <Steve_2E0VET> Miso and mosi is that a reference to the arduino I have only ever seen those on the sdcard
[12:02] <Steve_2E0VET> Argh the 6 pins at the back of the arduino by any chance
[12:02] <Darkside> its a standard ISP connector
[12:03] <HixWork> master input slave output master output slave input

[12:51] <ibanezmatt13> thanks, and that TPS61201 has given me an unbelievable amount of clearance errors
[12:51] <HixWork> ibanezmatt13 http://goo.gl/PKixw5
[12:51] <ibanezmatt13> Got it HixWork :)
[12:51] <HixWork> saw -too slow :)
[12:52] <Upu> I'll stick it up on github at some point
[12:52] <ibanezmatt13> that would be good

[12:55] <ibanezmatt13> If anybody's got a mo, I'm wondering how to correct the many many clearance issues around the TPS61201. I've only attached the .sch and .brd because I don't think a pic will be of any use :/ https://www.dropbox.com/sh/d6ttarxd7y0q3z4/MuJXp8NMyh

[12:57] Nick change: KipK_aw -> Kipkool
[12:58] <Babs> Has anyone here used the Easytransfer library by any chance?. I imagine the likelihood is no, but potentially worth asking on the off chance. Thanks.
[13:03] <Lunar_LanderU> Randomskk: as far as I know, you have to do three steps in kicad instead of two in EAGLE, 1.) schematic, 2.) footprints, 3.) routing, right?
[13:03] <Randomskk> ?
[13:03] <Randomskk> well I guess
[13:03] <Randomskk> you do those in eagle too really
[13:04] <Randomskk> kicad has more separated schematic symbols and pcb footprints
[13:04] <Randomskk> so yea, you do have to tell it what footprints each part should have
[13:04] <Randomskk> and you do that after the schematic if you like
[13:04] <Randomskk> but that's not really any different from picking them in eagle right at the start
[13:04] <Randomskk> I kinda prefer it
[13:04] <Randomskk> you can design a schematic quickly and without worrying about footprints
[13:04] <Randomskk> then only when it's time to make the pcb do you move on to thinking about footprints
[13:05] <eroomde> i don't like having to specify the actual physical part just to do the schematic, i must say
[13:05] <Randomskk> exactly
[13:05] <eroomde> and you often don't know
[13:05] <eroomde> first time round
[13:05] <Randomskk> I also like that kicad schematic symbols and pcb footprints are described by text files
[13:05] <Randomskk> so you can script stuff and edit things surprisingly easily
[13:05] <Randomskk> (though of course they have graphical editors)
[13:06] <Randomskk> I also like kicad's pcb routing stuff more than eagles I think
[13:06] <HixWork> ibanezmatt13 do you know you have VBATT going straight to the 328?
[13:06] <Randomskk> for one thing it (by default) simply won't let you violate DRC
[13:06] <Randomskk> you don't get to place a track that violates it
[13:06] <Randomskk> which is nice. and it shows outlines for all the DRC zones so you know what spacings to stick to.
[13:06] Joel_re_ (~jr@106.214.172.188) left irc: Ping timeout: 264 seconds
[13:06] <Randomskk> and it sticks little labels on all the traces so you know what's what
[13:06] <HixWork> is that for voltage monitoring?
[13:07] <ibanezmatt13> ok I'm back
[13:08] Joel_re (~jr@27.0.52.58) joined #highaltitude.
[13:08] <ibanezmatt13> HixWork: Yeah, I'm using a step up and the max VBATT voltage is 1.5v. So I'm going into an analog input
[13:08] <eroomde> i might give kicad a whirl
[13:09] <Randomskk> since you're so busy and all ;)
[13:09] <Randomskk> it being completely free/open source and with a text based file format appeals to me too
[13:09] <Randomskk> no limits on anything for free, and if you're making open hardware, anybody else can also actually use your stuff
[13:09] <HixWork> ibanezmatt13 why have you used polygons so much in that area?
[13:10] <Randomskk> it always bugged me when people released "open" hardware where all the design files are in proprietory formats that need expensive software to do anything with
[13:10] <Lunar_LanderU> Randomskk: we (my friends on the balloon team and I) want to go ahead and work with KiCAD, trying to understand it and all
[13:10] <Randomskk> there is a bit less in the way of tutorials online but there's enough to figure your way out
[13:10] <ibanezmatt13> The polygons for that part of things are better than tracks I believe HixWork. Means I can have wider connections. If I did it all with tracks the tracks wouldn't be very thick
[13:10] <Randomskk> there are a few good websites for parts libraries, but I pretty much exclusively make my own footprints for everything
[13:11] <Randomskk> been burned too many times by pre made footprints
[13:11] <Randomskk> spend as much time checking they are correct as making your own
[13:11] <eroomde> this is what i hear
[13:11] <Randomskk> mostly that burning happened in eagle
[13:11] <eroomde> the library ecosystem, footprints especially, is a pile of w*nk in comparison to eagle
[13:11] <Randomskk> haha really
[13:11] <Randomskk> idk
[13:11] <Randomskk> eagle is a bit better but I'd still mostly make my own
[13:11] <Randomskk> some sources are really good and some bad and it varies. kicad certainly ships with a lot less.
[13:12] <Randomskk> but like..
[13:12] <Randomskk> for anything really standard, whatever, it's fine
[13:12] <Randomskk> DIP and standard size SMT passives, no problem
[13:12] <Randomskk> for pretty much anything else it's likely niche enough that I want to make my own anyway
[13:12] <Randomskk> the only thing I really miss is sparkfun's eagle library
[13:13] <Randomskk> which was actually a) really good b) corresponded 1:1 with sparkfun parts and part numbers
[13:13] <ibanezmatt13> HixWork: Is it possible to correct those clearance and width errors without causing too much bother
[13:13] <eroomde> if the package editor is good, i'd be not too bothered about such a thing anyway
[13:13] <Randomskk> yea it's nice
[13:13] <Randomskk> special love for its very very easy relative positioning
[13:13] <Randomskk> hitting space sets the reference point
[13:13] <eroomde> that would be nice
[13:13] <Randomskk> so you always have absolute position, but next to them it shows the distance (in cartesian or polar) to the reference
[13:13] <Randomskk> which means dimensioned drawings are easy: hit space at one side, get to the right relative distance
[13:13] <HixWork> ibanezmatt13 i dont really see what the VBATT plygon is doing lower right, its just creating a pour that doesn't really add to anything
[13:14] <Randomskk> I believe eagle can do that but it's more faffy
[13:14] <ibanezmatt13> HixWork: Page 17: http://www.ti.com/lit/ds/symlink/tps61200.pdf
[13:16] <Lunar_LanderU> yea for example, on element14 are a lot of EAGLE libraries for each manufacturer
[13:16] <eroomde> although some of the symbols are shit
[13:16] <Lunar_LanderU> and in KiCAD you have to edit your own footprints and so on?
[13:16] <Randomskk> yea farnell buying eagle did lead to a lot of parts
[13:17] <eroomde> like, stand up against the wall to be shot, you awful designer, shit
[13:17] <Randomskk> Lunar_LanderU: yea, for non-standard things
[13:17] <Randomskk> eroomde: in what, farnell?
[13:17] <eroomde> yes
[13:17] <Randomskk> huh. I'd have thought they could have tried a bit.
[13:17] <eroomde> totally totally wank
[13:17] <Lunar_LanderU> ok, but I think stuff like atmegas, resonators, MOSFETs should be in
[13:17] <eroomde> a 4 channel op amp package, say
[13:17] <Randomskk> never used any of them though, swapped to kicad before farnell bought eagle
[13:17] <Lunar_LanderU> I think many things have generic footprints anyway
[13:17] <Randomskk> Lunar_LanderU: many of those will, but mosfets come in literally hundreds of different packages, it's not gonna have them all
[13:17] <eroomde> instead of the symbol being 4 triangles, like it should be, it'll be one big recantagle
[13:17] <eroomde> with
[13:17] <Lunar_LanderU> yeah
[13:17] <Randomskk> TO220? sure, it's got that
[13:17] <Lunar_LanderU> that's the one
[13:17] <Lunar_LanderU> :)
[13:18] <Randomskk> eroomde: haha wtf
[13:18] <eroomde> in1,out1,in2,out2,in3,out3,in4,out4 on one side
[13:18] <Randomskk> oh christ
[13:18] <eroomde> or whatever
[13:18] <eroomde> just shit
[13:18] <Randomskk> that's pathetic
[13:18] <eroomde> yes i know
[13:18] <Lunar_LanderU> on which program is that?
[13:18] <eroomde> i nearly vomited
[13:18] <eroomde> eagle
[13:18] <Lunar_LanderU> oh
[13:18] <Randomskk> it should be four separate triangles in four parts that belong to one package with the whole magic power supply pins taken care of too >_>
[13:18] <Lunar_LanderU> I remember that there are OpAmps where you place the triangles
[13:18] <eroomde> yes exactly
[13:18] <Lunar_LanderU> and you get IC1A, 1B...
[13:18] <Randomskk> yes
[13:18] <eroomde> yes exactly lunar
[13:18] <Randomskk> that's how it should be Lunar_LanderU
[13:18] <eroomde> that's whow it should be
[13:19] <Lunar_LanderU> I did that
[13:19] <Randomskk> apparently someone was being lazy or didn't know any better
[13:19] <Lunar_LanderU> I think it's a national instruments OpAmp that is in
[13:19] <Lunar_LanderU> LMC6042
[13:21] <eroomde> http://i.imgur.com/sjP1X7b.png
[13:21] <eroomde> from one of my designs
[13:21] <eroomde> charitably, he didn;t know better
[13:21] <eroomde> but it's basically worthless
[13:21] <eroomde> you end up having to redo it yourself anyway, having wasted time looking at their stuff
[13:21] <Randomskk> yea.
[13:22] <Randomskk> the only thing I find annying about making your own symbols is that I never get sizes consistent with other library parts or something
[13:22] <Randomskk> end up with weirdly small resistors or overly large diode bridges or something
[13:22] <Randomskk> e.g. https://randomskk.net/u/headamp.pdf
[13:22] <Randomskk> that diode bridge D1 is a library part
[13:22] <Randomskk> and wtf it's huge
[13:22] <Randomskk> SW1 is a library part: also huge
[13:22] <Randomskk> J1 and J2 in the bottom right are my own parts: probably smaller than they should be
[13:23] <Lunar_LanderU> XD the diodes
[13:23] <eroomde> yes
[13:23] <eroomde> odd
[13:23] <Randomskk> I mean compare the size of the diodes to the transformer next to them
[13:23] <Lunar_LanderU> xD the voltage warning
[13:23] <Lunar_LanderU> yea
[13:23] <Randomskk> clearly you're going to have that diode bridge next to that transformer in like 80% of circuits that use both
[13:24] <Randomskk> so why make them such a stupid size
[13:24] <Randomskk> answer: no reference when making symbols
[13:24] <Randomskk> you zoom in and out and the grid adjusts and who knows how big a thing is
[13:24] <Lunar_LanderU> oh
[13:24] <Lunar_LanderU> also what I am thinking of all the imte
[13:24] <Lunar_LanderU> time
[13:24] <Lunar_LanderU> why is the EAGLE grid set to inch by default?
[13:24] <Randomskk> I think it'd be cool if you could draw schematic symbols _inside your schematic_
[13:24] <Randomskk> then you'd be sorted
[13:24] <Randomskk> Lunar_LanderU: because it's american
[13:25] <Randomskk> and also because the electronics industry is still mostly imperial
[13:25] <Randomskk> (maybe eagle is german?)
[13:25] <Randomskk> (yea it is)
[13:25] <mattbrejza> and because spacings of .1"
[13:25] <Lunar_LanderU> ah
[13:26] zamabe (zamabe@unaffiliated/zamabe) joined #highaltitude.
[13:26] <mattbrejza> components are still called 0603,0805 etc which is imperial measurements
[13:26] <Randomskk> you can actually get metric smt
[13:26] <mattbrejza> but i guess its moving on, with QFN being 0.5mm
[13:26] <Randomskk> who thought that was a good idea
[13:26] <mattbrejza> 0.65mm etc
[13:26] <mattbrejza> yea farnell give metric dimensions
[13:26] <mattbrejza> in brackets
[13:26] <Lunar_LanderU> yea
[13:27] <Randomskk> no I mean hard metric sizes
[13:27] <Randomskk> oh huh
[13:27] <Randomskk> I see what you mean
[13:27] <Randomskk> I think that's newish?
[13:27] <Randomskk> 0603 in metric is 0201 in imperial >__>
[13:27] <eroomde> yes it's confusing
[13:27] <eroomde> i have printed the diagram on the wikipedia smd page
[13:28] <mattbrejza> bearing in mind '0603' is now more of a name rather than a guide of how big it is, would be silly to change
[13:28] <eroomde> http://upload.wikimedia.org/wikipedia/commons/3/34/SMT_sizes%2C_based_on_original_by_Zureks.svg
[13:28] <Randomskk> good diagram
[13:28] <mattbrejza> i tend to route in mil as 25mil is just a nicer number than whatever the metric is
[13:28] <eroomde> sometimes i consider the amount of charge required and say 'i think that needs to be about 2010 size'
[13:29] <eroomde> and design around that
[13:29] <Randomskk> all my PCBs are in metric now I think
[13:29] <Randomskk> .5mm grid is ok
[13:29] <Randomskk> or .25mm
[13:29] <Randomskk> and you can use like .2 and .3mm wide tracks
[13:29] <Randomskk> but tbh mil is still a more helpful way of doing things at this size scale
[13:29] <eroomde> i wish parts would switch to metrix
[13:30] <mattbrejza> the numbers are pretty meaningless at this scale so mil will do fine for me
[13:30] <Randomskk> I have a better intuition about spacings and clearance and current capacity in mil than mm
[13:30] <Randomskk> like 6mil is a very thin trace, but 0.2mm? I'd pretty much have to convert to mil first
[13:31] <Randomskk> still I like the theory of metric so I mostly use that
[13:31] <Randomskk> kicad makes it fairly easy
[13:32] <mattbrejza> shame theres no eagle -> kicad lib conversion (or is there...?)
[13:32] <Randomskk> yea I believe there is
[13:32] <Randomskk> never tried it though
[13:32] <mattbrejza> hmm
[13:36] <mattbrejza> Randomskk: is editting the schematic after starting the pcb annoying in kicad?
[13:36] <Randomskk> depends what you mean by annoying
[13:36] <Randomskk> gonna say "no"
[13:37] <mattbrejza> reading http://dangerousprototypes.com/2012/09/14/dangerous-prototypes-kicad-eda-experience/
[13:37] <Randomskk> so the way it works is you make your schematic, you export a netlist, then you read that in the pcb editor
[13:37] <Randomskk> the editor can keep components based on reference or swap them etc so you can decide what it does
[13:37] <Randomskk> editing connections is no problem, editing parts generally works out fine
[13:37] <Randomskk> it doesn't do the weird eagle thing where back annotation gets horribly broken
[13:38] <Randomskk> but I don't think I've ever used back annotation in kicad (it does have it)
[13:38] <mattbrejza> well i guess teh eagle thing works better until it breaks?
[13:38] <Randomskk> not sure about better. it's been a while since I've used it. it's more immediate/quicker I guess
[13:38] <HixWork> ibanezmatt13 the ground pour was overlapping the polygons, changing the route for the ground pour results in this http://i.imgur.com/4CJkcfW.png don't know if thats any help?
[13:39] <Randomskk> "Minor adjustments to a schematic after starting the board are a nightmare. You have to create a new netlist, loading it into the PCB editor, and update the PCB connections."
[13:39] <Randomskk> this seems an exaggeration
[13:39] <Randomskk> it takes like 3 seconds
[13:39] <mattbrejza> :P
[13:39] <Randomskk> two clicks in the sch editor, then swap to the pcb editor and another two clicks
[13:39] <mattbrejza> i guess i could give it a go
[13:39] <mattbrejza> its not as if i have anything better to do atm...
[13:39] <Randomskk> "Placing vias on polygons/planes is too complicated, such as vias to join ground planes. You have to trace each via to an already existing trace or pad and connect to it."
[13:39] <Randomskk> this is my only annoyance
[13:39] <mattbrejza> actually might go downstairs for a spot of soldering
[13:39] <ibanezmatt13> HixWork: That looks a lot better. What did you do to the ground plane? Did you only make it on the bottom or something
[13:40] <Randomskk> vias dont have nets explicitly, only by what traces they are on
[13:40] <Randomskk> so you have to basically start on a ground pad and wire, laying vias as you go
[13:40] <mattbrejza> is it still in active development?
[13:40] <Randomskk> the good news is that laying vias is super easy
[13:40] <mattbrejza> will these things get sorted
[13:40] <Randomskk> yes it is
[13:40] <Randomskk> I imagine they will
[13:40] <Randomskk> well the via thing
[13:40] <Randomskk> but it's not a huge deal tbh
[13:40] <HixWork> ibanezmatt13 you had the whole board top layer surrounded, just cut out the section where you ewanted other sruff
[13:40] <Randomskk> just a bit silly
[13:40] <mattbrejza> ok
[13:40] <mattbrejza> the active drc thing seems good
[13:41] <ibanezmatt13> which section is that HixWork? The entire TPS61201 section?
[13:42] <HixWork> ibanezmatt13 one thing that would prob help even more is if you have the centres of all the caps etc fgor that ic line up with its centre. to quote the spec sheet "the layout is an important step in the design" don't just emulate the image
[13:42] <Randomskk> oh my god the comments
[13:42] <ibanezmatt13> ok, I can do that part
[13:42] <Randomskk> >>>
[13:42] <Randomskk> You sound a bit harsh with EAGLE. Its not that bad :-)
[13:42] <Randomskk> Have you considered trying to scale everything down to work around the EAGLE size limitation? For example instead of making a board 10 inches wide, you make it 10 millimeters wide. This requires scaling all libraries down, and then scaling the output gerber files up. But this can be automated with a few basic scripts.
[13:43] <mattbrejza> haha
[13:43] <mattbrejza> o dear
[13:43] <mattbrejza> might as well just get it from tpb
[13:44] <HixWork> remember ibanezmatt13 there is a whacking great via connecting top to bottom so the top ground pour is connected, instead of the square covering all the top layer, cop the bottom right corner out of it
[13:45] <ibanezmatt13> yeah, see what you mean. Thanks :)
[13:46] <HixWork> ibanezmatt13 incidentally, why the boost converter?
[13:46] <ibanezmatt13> Well, I fancied a change from the usual step down converters. Means I can power the whole thing of a AA, I gain more knowledge, and I learn more Eagle :)
[13:47] <mattbrejza> are you gonna bother with board v1 when it arrives?
[13:48] <ibanezmatt13> of course, I probably won't get v2 made for ages
[13:48] <ibanezmatt13> I'm just making loads of different versions with different things on it to get better at Eagle :)
[13:48] <mattbrejza> ah
[13:48] <HixWork> ibanezmatt13 bottom tracks on R1 and R6 are intersecting
[13:49] <ibanezmatt13> are they? better change that, well spotted
[13:49] <ibanezmatt13> oh no I changed that HixWork
[13:49] <ibanezmatt13> I forgot to upload a new version
[13:49] <HixWork> remember ERC not just DRC
[13:49] <HixWork> it'll highlight things like that if you don't spot em
[13:50] <ibanezmatt13> I've done ERC and it's ok. The warnings I've approved. The DRC is the problem
[13:51] <HixWork> sorry, overlap is in DRC but it does show it
[13:51] <Lunar_LanderU> Randomskk: where are the citations above from?
[13:51] <Randomskk> http://dangerousprototypes.com/2012/09/14/dangerous-prototypes-kicad-eda-experience/
[13:51] <Lunar_LanderU> ah
[13:52] <Lunar_LanderU> yeah just found it
[13:52] <ibanezmatt13> HixWork: I've just changed that top ground plane to bypass the TPS61201. DRC is a lot nicer now
[13:53] <Lunar_LanderU> btw
[13:53] <HixWork> ibanezmatt13 cool cool
[13:53] <Lunar_LanderU> why is EAGLE Light $69 and has the same restrictions than EAGLE free?
[13:53] <ibanezmatt13> Ah, HixWork the DRC shows I still have a few (a lot less than before) clearance, keep out and width errors :(
[13:53] <HixWork> ibanezmatt13 did you line all the caps to the centre cross of the 61201?
[13:53] <ibanezmatt13> Not just yet, will do now
[13:54] <ibanezmatt13> Lunar_LanderU: I've got Light, it was free
[13:54] <Randomskk> no
[13:54] <Randomskk> Light is OK for commercial usage
[13:54] <Randomskk> Free is only for non profit
[13:55] <Randomskk> both have same board size restrictions
[13:55] <ibanezmatt13> HixWork: The caps look pretty inline don't you think?
[13:55] <HixWork> not the centres
[13:56] <ibanezmatt13> the centres of all caps for the tps61201 should be aligned?
[13:56] <ibanezmatt13> on the example layout in the datasheet, it looks like the ground side of the caps are aligned and the other sides are aligned

[15:07] <Willdude123> Netbook
[15:08] <Willdude123> BBB
[15:08] <mfa298> powering the BBB from a netbooks USB. Power could be your issue there.
[15:08] <mfa298> USB is 500mA tops (from memory) but your netbook might not even provide that.
[15:09] <mfa298> so once the BBB is powered there might not be much power left for the GPS.
[15:10] <mfa298> get the GPS working with the ftdi first. If you can't get that to work there's not much point trying with the BBB
[15:10] <mfa298> back to one of the things dave said yesterday. You currently have a lot of unknowns. You need to rule some of them out.

[16:12] <Willdude123_> Outside with ftdi
[16:12] <Willdude123_> Which means.
[16:12] <Willdude123_> BBB uses too much current
[16:13] <Willdude123_> I could check the supplied current to the Ublox
[16:13] <Willdude123_> From the BBB
[16:13] <Willdude123_> See if it's enough
[16:13] <Willdude123_> Otherwise, I might have to use raw 5v and step it down
[16:13] <mfa298> If you're powering the BBB from USB I think you'll be at the limits of the current available.
[16:14] <Willdude123_> HMm
[16:14] <mfa298> You might be better off getting a suitable adapter so you can run the BBB off a DC supply rather than usb
[16:14] <Willdude123_> I have one,
[16:14] <Willdude123_> But they don't work outside, as there are no mains plugs outside
[16:15] <mfa298> from a quick look at the BBB docs last night you might also want to try VCC_3V3B instead of VCC_3V3A (if that's what you've been using)
[16:16] <Willdude123_> Why, are they different?
[16:16] <mfa298> you mean you've not read the bits about how the BBB supplies power.
[16:17] <mfa298> on this channel you should be the BBB expert!

[16:17] Dumorimasoddaa (~heliossch@smtp.vorticity-systems.com) left irc: Quit: Dumorimaosddaa away!
[16:18] <Willdude123_> They both should be able to provide 250ma
[16:18] <mfa298> I'm sure you said it could provide 400mA last night.
[16:18] <Willdude123_> Don't think I did
[16:19] <mfa298> from what I read last night it looked like 3V3A was also powering parts on the board
[16:19] <Willdude123_> Hmm
[16:20] <mfa298> ah sorry, my mistake looks like you did say 250mA
[16:20] <mfa298> you might need to check how much power the ublox needs especially if that's an active antenna you've got.
[16:21] <Willdude123_> 3v3a isn't broken out as a pin
[16:21] <Willdude123_> 150ma IIRC
[16:21] <Willdude123_> Anyway, I'm going to retire for the day, to avoid getting too frustrated.
[16:21] <Willdude123_> Wifi is a real pain on the BBB
[16:22] <mfa298> if it's an active antenna it could be a bit more (I don't know if it's passive or active)
[16:22] <Willdude123_> Nor do I
[16:22] <Willdude123_> Right, I will do some more testing tomorrow.
[16:22] <Willdude123_> Actually
[16:22] <Willdude123_> I could check the current supplied
[16:22] <Willdude123_> Using a multimeter
[16:23] <mfa298> you might only see an average current although it should give an idea of whats needed
[16:24] <cde> Willdude123_: see? there _was_ a logical explanation ;)
[16:24] <Willdude123_> Is the current load that I see the same as the max current it will provide? ie if the board uses 100ma, BBB can provide 50ma what would I see
[16:25] <daveake> Willdude123 What is providing the power to the BBB?
[16:25] <Willdude123_> USB on my netbook
[16:25] <Willdude123_> Will it help me understand if it's underpowered?
[16:26] <cde> Willdude123_: I asked about this on #beagle a few days ago. but there was no conclusive answer
[16:26] <Willdude123_> Hmm ok
[16:26] <Willdude123_> Thanks for asking :)
[16:27] <cde> ah well I noticed the guys on #beagle spend more time trolling than helping
[16:28] <Willdude123_> Heh
[16:28] <Willdude123_> How were they trolling you?
[16:28] <cde> oh not me specifically
[16:28] <Willdude123_> Hmm maplin live chat
[16:29] <Willdude123_> To troll or not to troll
[16:31] <daveake> OK, the 3.3V line on the BBB is supplied from the LDO in a TPS2141 and that has a maximum current rating of 250mA-500mA
[16:32] <daveake> As the 3.3V isn't used for much else that /should/ be enough
[16:32] <Willdude123_> But isn't.
[16:32] <daveake> How do you know?
[16:32] <Willdude123_> How much does the NTX2 use.
[16:32] <daveake> 20mA
[16:33] <Willdude123_> Well, I suppose it's just a guess.
[16:33] <Willdude123_> Will check with a multimeter how much current is supplied
[16:33] <daveake> There's a quote in Apollo 13 about guessing
[16:33] <eroomde> we have a new approach to coping with mondays at work

[16:33] <daveake> The BBB has some pins where you can measure the current. It's in their wiki
[16:34] <daveake> Anyway ... if you don't get lock without the BBB, then you might as well ignore the BBB for now
[16:35] <Willdude123_> I did though with the FTDI
[16:36] <daveake> In that case, repeat that, then power up the BBB and put it near the antenna (with the ublox still running from the FTDI)
[16:36] <Willdude123_> OK
[16:37] <Willdude123_> Will do, at some point
[16:37] <Willdude123_> I've retired for the evening

[16:37] <mfa298> That's a good test. And when you get to trying the GPS with the BBB try DC power rather than USB.
[16:37] <x-f> mystery*
[16:38] <Willdude123_> But no DC power anywhere where I can get lock
[16:39] <Willdude123_> eroomde: Don't you have exciting mondays at work?
[16:39] <Willdude123_> You could just go and burn something

[16:40] <eroomde> and i drove straight from clapham to work at 6am this morning
[16:40] <eroomde> today was never going to be exciting
[16:40] <Willdude123_> Hm yes
[16:40] <eroomde> and also going cold turkey on drink after the last few days would probably not be good either
[16:41] <Willdude123_> Is 9v OK?

[16:42] <mfa298> apparently there are these magical devices called extension leads.
[16:42] <daveake> wow cool :)

[17:17] <ibanezmatt13> ^^ yes
[17:17] <Willdude123> Let me rephrase that.
[17:17] <Willdude123> How much does it cost?
[17:17] <Willdude123> Good advice mfa298
[17:18] <mfa298> that's even true when using an old skill - When I'm writing code I write a bit and compile often to check it's working
[17:18] <ibanezmatt13> to give you a rough idea, I'm expecting 10 boards for about £16
[17:18] <Willdude123> Why 10?
[17:18] <ibanezmatt13> 10 for the price of 5 is on at hackvana
[17:18] <ibanezmatt13> 5 is minimum quantity
[17:19] <Willdude123> Does he give quotes or fixed prices?
[17:19] <ibanezmatt13> check hackvana.com
[17:19] <ibanezmatt13> he gives quotes
[17:19] <ibanezmatt13> of course, depending on type of board, size of board, colours of soldermask and silkscreen the prices differ

[18:31] <Steve_2E0VET> does a gps still transmit NMEA strings if it cannot see sats (i.e if its in a room with no windows)
[18:32] <mfa298> you'll likely get some sentences but not all fields will be filled in
[18:32] <Steve_2E0VET> mfa298, I am getting the strings but with nulls in the value, for want of a better word
[18:33] <Steve_2E0VET> just bought one of these hope it works http://www.ebay.co.uk/itm/271172859271?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1439.l2649
[18:33] <Iain_G4SGX> Hi y'all. Does anyone know if the Max6 needs some time to start before I can send it the NMEA-OFF UBX string? Doesn't seem to react and Im sure the string is correct
[18:34] <Steve_2E0VET> mine doesnt have any delays programmed, then again im probably not the best person to ask lol
[18:35] <Iain_G4SGX> ok, wil double check, maybe stick a delay in see what happens
[18:35] <Iain_G4SGX> tnx
[18:36] <Steve_2E0VET> Iain_G4SGX, are you getting anything out of it?
[18:36] <Steve_2E0VET> i wonder what the range is on a 10mw transmitter
[18:36] <Iain_G4SGX> All the NMEA strings are all being sent ok, wanna tuern them off and parse for ACK
[18:37] <Iain_G4SGX> Using UBX
[18:38] <Steve_2E0VET> argh ok, in that case the script i was using did have a 2.5sec delay, but i have gone back to basics and left UBX alone
[18:39] <Iain_G4SGX> I think its sending too soon before the max has setup, 1st thought anyway..
[18:39] mclane (~uli@pD9E2C80E.dip0.t-ipconnect.de) joined #highaltitude.
[18:41] <Lunar_Lander> Steve_2E0VET, as far as I know, GPS automatically output NMEA sentences if powered
[18:41] <Lunar_Lander> and if there is no satellite lock, it is like all 999999 I think
[18:41] <Iain_G4SGX> Easier still, I'll repeatedly send the control bytes see what happens.. Mine send NMEA strings at startup whether or not its locked
[18:41] <Steve_2E0VET> Lunar_Lander, yeah thats what i get
[18:41] <fsphil> coordinates 0,0
[18:42] <fsphil> but it'll always put out nmea strings unless you tell it not to

[18:50] <Steve_2E0VET> just to clarify something, say i'm in the house with no sat reception and take it outside, will it automatically start working or do you need to send it "startup" commands
[18:51] <mfa298> it should start working when it sees some sats
[18:51] <Steve_2E0VET> right
[18:51] <Iain_G4SGX> Yep def a timing issue, without a delay takes about 1.5 secs to react, stop NMEAs and send ACK, I think most of that is MAx starup time and a 1 sec delay is needed..
[18:51] <mfa298> if it's near a window you might see one or two sats at which point you should see time/date but won't get a position
[18:52] <Steve_2E0VET> i bust my antenna when i droped it on the floor, i have got a huge randiosonde antenna on at the mo
[18:52] <Steve_2E0VET> has cyclops uploaded any images yet?

[19:28] <ibanezmatt13> I spent a while trying to sort that TPS61201 but kept getting a load of errors on the DRC; I've given up on it for tonight
[19:29] <Upu> link
[19:29] <ibanezmatt13> https://www.dropbox.com/sh/d6ttarxd7y0q3z4/MuJXp8NMyh
[19:29] <ibanezmatt13> I was pleased with most of the board
[19:30] <ibanezmatt13> I don't really need to design another PCB. I just want to keep learning Eagle so I thought I'd make another PCB for the fun of it :)
[19:30] <ibanezmatt13> Plus I'm interested in the step up boost converters
[19:31] <eroomde> if truely interested in the electronics, www.linear.com/docs/4120
[19:32] <eroomde> this is by one of the legends on analogue design
[19:32] <eroomde> of*
[19:32] <ibanezmatt13> thanks eroomde, I'll have read of that later on
[19:32] <mclane> hi Lunar_Lander
[19:32] <eroomde> it might assume a bit more electronics than you have precisely right now
[19:32] <eroomde> but nothing too advanced
[19:33] <ibanezmatt13> Randomskk explained how the step up worked with the inductor and capacitors and I was really quite interested
[19:33] <ibanezmatt13> Yeah, still worth a little read
[19:33] <Upu> ibanezmatt13 https://join.me/237-993-229
[19:33] <Laurenceb_> ok im very confused now
[19:33] <Laurenceb_> http://www.interpals.net/LaurenceB
[19:33] <Laurenceb_> what the heck
[19:33] <Laurenceb_> someone is trollifying
[19:33] <eroomde> yes, you can probably see how that works from that equation i told you about the other day
[19:34] <eroomde> V = L*(di/dt)
[19:34] <eroomde> so if you have current flwing through an inductor, and you suddenly switch it off (with a transistor say), then all of a sudden there's no current flwing through the inductor
[19:34] <eroomde> so the rate of change of current (di/dt) is very large
[19:34] <eroomde> and L is fixed
[19:35] <Upu> tracks are too thick
[19:35] <eroomde> so that means the voltage shoots right up
[19:35] <eroomde> and you can use a capacitor to absorb that spike of high voltage
[19:35] <eroomde> and provide it more steadily to the right of the circuit
[19:35] <eroomde> et voila, a boost converter
[19:35] <eroomde> i guess adam explained all this
[19:38] <Iain_G4SGX> Very well explain eroomde, you should be a teacher..
[19:38] <eroomde> come to my talk on how to build a gps receiver at the conf!
[19:39] <fsphil> it's a good skill to have. I'm horrible at explaining things
[19:40] <Upu> there you go ibanezmatt13
[19:40] <Upu> I think you've struggled with that part
[19:40] <ibanezmatt13> wow
[19:40] <Iain_G4SGX> Wish I could, got a work commitment, timing is terrible for me. Got tickets anyway so who knows.
[19:40] <Upu> but shouldn't make a differnece
[19:40] <ibanezmatt13> extremely
[19:40] <ibanezmatt13> Can you ignore keep out and width errors?
[19:41] <eroomde> i ignore keep-out errors :)
[19:41] <eroomde> width i try and fix
[19:41] <ibanezmatt13> I have a load of width errors too
[19:41] <eroomde> if it's, for example, track width used to make polygons
[19:41] <Upu> depends
[19:41] <Upu> I would check each one
[19:41] <Upu> see that
[19:41] <Upu> you can ignore that

[19:42] <eroomde> with DRC reports
[19:42] <Upu> you have Silk over the pad
[19:42] <Upu> could cause issues when soldering
[19:42] <Upu> thats ok
[19:42] <ibanezmatt13> Ah ok
[19:43] <Upu> width ones are because you have used 0 width polygons
[19:43] <ibanezmatt13> right, so they can be dismissed?
[19:44] <Upu> yes
[19:44] <ibanezmatt13> thanks Upu, I'll see if I can change it

[20:57] <Willdude123> Will do more testing tomorrow
[20:57] <cde> life on earth. it never gives up!
[20:57] <Willdude123> I'll check if it's getting the required current with a multitester.
[20:57] <Willdude123> And see if bringing it close to the GPS stops it from getting lock.
[20:57] <Steve_2E0VET> Willdude123, TinyGps working first time!!
[20:58] <Upu> out of interest ibanezmatt13 why no GND plane on the top round the regulator ?
[20:58] <Willdude123> Well done Steve_2E0VET
[20:58] <ibanezmatt13> it was causing me issues earlier. Shall I put it back?
[20:58] <Steve_2E0VET> Willdude123, now to implement RTTY
[20:58] <Upu> no reason not to have it
[20:59] <ibanezmatt13> I'll put it back.
[20:59] <Upu> all looks ok
[20:59] <Willdude123> Upu I think you labelled something wrong on the Habduino schematic. TXE_N IIRC
[20:59] <ibanezmatt13> Would it make sense to have the main ground plane of the board continue over it or just a new one?
[21:00] <Steve_2E0VET> Upu, are the ublox designed to run at 9600
[21:00] Nick change: Kipkool -> KipK_aw

[21:00] <Upu> by default

[21:00] Nick change: KipK_aw -> Kipkool
[21:00] <Upu> yep
[21:01] <Willdude123> It was labelled N_TXD, it's N_TXE Upu

[21:16] <Upu> you're using polygons with a rank of 1
[21:17] <ibanezmatt13> why did that cause all the errors around the TPS61201?

[21:55] <Upu> pins 0 & 1 ?
[21:55] <Steve_2E0VET> mines now connected on pins 0/1(tx/rx)
[21:55] <Upu> ah ok thats probably your issue
[21:55] <Steve_2E0VET> Upu, ?
[21:55] <Upu> Arduino uses those to program it
[21:56] <Steve_2E0VET> i use 8/9 to program
[21:56] <Upu> yeah but when you program the arduino it uses 0 and 1
[21:56] <Steve_2E0VET> could use any but thats all i had free
[21:56] <Steve_2E0VET> Upu, i disconnect the gps first
[21:56] <Upu> ok
[21:56] <Steve_2E0VET> it all works ok for me
[21:56] <Upu> you can just stick some 1k resistors on the RX and TX lines
[21:56] <Upu> that should mean you can leave it connected
[21:57] <Steve_2E0VET> i have bought one of those programmers to allow it to be connected at the same time, ok would have been cheaper to get 2 resistors
