[09:03] <Darkside> 1.2d normally
[09:03] <Darkside> in the hakko range
[09:08] <gonzo_> I have a 5mm chilse tip that gets used for everything, no matter how fine. Certainly gets the heat to the job. (Weller therma-lock iron, electromic version of the magnastat)

[09:18] <fsphil> I've a cheapy maplin iron, but I like it
[09:18] <fsphil> trying out using an oven and solder paste atm
[09:23] <gonzo_> seen interesting reflow oven bade from there little bedsit sized ovens, with improced temp ctrl
[09:24] <gonzo_> made
[09:26] <fsphil> this is similar, just a toaster oven from argos
[09:27] <fsphil> still not quite got the hang of getting the proper amount of paste onto the pad
[09:28] DoNcK (jverdonc@leonard.irisa.fr) left #highaltitude.
[09:34] <gonzo_> think paste masks are usually only a couple of thou thick
[09:34] <fsphil> they are
[09:35] <fsphil> I try to smear a bit of paste onto the pad, rather than a blob
[09:35] <zyp> I wouldn't do paste without a stencil
[09:35] <fsphil> I think my problem last time was I'd not let the paste warm up after taking it out of the fridge
[09:35] <gonzo_> ah, a worm the
[09:35] <zyp> it's hard enough to get right with a stencil :p
[09:35] <gonzo_> then
[09:36] <jonsowman> zyp: it's not difficult for 0603 and up
[09:36] <jonsowman> even 0402 is fine
[09:36] <jonsowman> stereo microscope is a great help
[09:36] <fsphil> I'd use a stencil if I was making more than a couple :)
[09:36] <jonsowman> it's certainly more time consuming
[09:36] <fsphil> but for now the syringe is fine
[09:36] <zyp> I'm mostly doing 0603 and down :p
[09:36] <gonzo_> I've tinned the pads with an iron and stuck the device on top before now
[09:37] <zyp> what's the complexity of the boards?
[09:37] <gonzo_> just out a smear of flux on. That was with an IR reflow, for localised repairs
[09:37] <fsphil> I'm still at the practicing on scrap board stage :)
[09:37] <zyp> ah
[09:38] <fsphil> gonna try at atmega tonight
[09:38] <gonzo_> i was reworking 132qfp devices
[09:38] <zyp> http://bin.jvnv.net/f/g17eb.JPG <- this is the last board I did, the passives are mostly 0603
[09:39] <zyp> I wouldn't want to do QFN without a stencil
[09:39] <fsphil> good looking board
[09:40] <gonzo_> also found that when the solder melts, the surface tension tended to pull the devices into alignment on the pads
[09:40] <UpuWork> uff that looks like an antenova ...
[09:40] <fsphil> yea I've seen that too gonzo_
[09:41] <zyp> UpuWork, yep
[09:41] <fsphil> I intentionally placed a resistor on at an angle, and it corrected itself
[09:41] <zyp> http://bin.jvnv.net/f/sTW8U.JPG <- assembled pic
[09:41] <gonzo_> shame we onlyb have a hot air rework stn here
[09:41] <gonzo_> I miss having the facility of IR
[09:41] <UpuWork> got a nice oven ?
[09:42] <zyp> gonzo_, I've found that for 0402 parts, the two sides may melt at a slightly different time, and the side that melts first will raise the resistor/cap up on one edge
[09:42] <zyp> it's called tombstoning
[09:43] <UpuWork> nice board though
[09:43] <fsphil> yea
[09:43] <fsphil> 0402 is a scary thought
[09:43] <griffonbot> @vk5gr: #ProjectHorus now starting to compile the footage from Horus 26 & 27 flights last weekend - oh my there is a lot to edit here! [http://twitter.com/vk5gr/status/208493948828790784]
[09:43] <zyp> the main reason I did 0603 rather than 0402 on this board is that I got tired of reworking tombstones
[09:43] <gonzo_> yes had seen that too. Though I was usually doing big arsed chip's for the work's jobs
[09:44] <zyp> 0402 is not much harder than 0603 to work with, reworking is just so tedious
[09:44] <zyp> :p
[09:44] <gonzo_> I an usually heavy on the flux which tends to puddle the parts to the board!
[09:44] <zyp> UpuWork, you don't like antenova?
[09:44] <fsphil> I find the components stick to the tweezers a lot
[09:45] <zyp> fsphil, clean your tweezers regularly
[09:45] <fsphil> will do
[09:45] <fsphil> though they looked fairly clean, I guess there could be some paste on there or something else
[09:45] <daveake> Probably doesn't need much
[09:46] <UpuWork> never used it but they look hard to hand solder and melt if you point a hot air so I stick to MAX6
[09:46] <zyp> just have a bit of paper and cloth available and pull a bit on it with the tweezers when components start sticking
[09:46] <fsphil> managed to lose 4 0603 resistors last night
[09:46] <zyp> paper or cloth*
[09:46] <UpuWork> the chip antenna + MAX6 weighs the same 1.5g on a PCB
[09:46] <gonzo_> zyp, any idea why the smaller devices tended to heat irregularly?
[09:47] <zyp> less mass so less force needed to raise them
[09:47] <fsphil> weird to think that an 0603 has any weight at all :)
[09:47] <UpuWork> it does :)
[09:47] <gonzo_> gravity is a bugger.
[09:48] <zyp> it's also 50% longer
[09:49] <zyp> UpuWork, and yes, I bought a cheap chinese reflow oven
[09:49] <zyp> http://bin.jvnv.net/f/lNfIS.JPG
[09:49] <UpuWork> yeah considering one of those
[09:49] <UpuWork> oh that exact one
[09:50] <zyp> I'm not mass producing anything, so it's working okay for me

[10:02] <Upu> seems not
[10:02] <Upu> which is a shame
[10:02] <Bob_G8NSV> just about to say that!
[10:02] <Upu> just have to polish the antennas
[10:02] <daveake> If I had a foil balloon I'd go fly that just to keep y'all busy :)

[10:04] <Bob_G8NSV> never mind, I have my rainy day plan in hand. Got all the bits for my payload now, second rfm 22b so I dont have to break down my breadboard version
[10:04] <Bob_G8NSV> and got more antenna work to do
[10:04] <UpuWork> yup
[10:05] <kokey> how has the rfm22's been performing?
[10:05] <daveake> So how does that work, UpuWork? "Sorry luv, I can help with the housework, I've got to go polish my antenna"?
[10:05] <daveake> can't*
[10:06] <Bob_G8NSV> had no probs with mine, used Navracs code as the basis and altered it for my gps module and removed the uplink which I'm not using
[10:06] <kokey> he said antennas
[10:07] <kokey> Navrac's code?
[10:07] <Bob_G8NSV> yeah its a combination of lots of peoples stuff really, J Sowman and a loty of others
[10:07] <Bob_G8NSV> for the arduino
[10:08] <Bob_G8NSV> uses the rfm libraries and tiny gps
[10:08] <kokey> ah ok
[10:08] <zyp> UpuWork, some people like them, some people dislike them, I only care about it being a cheap four-layer pcb :p
[10:09] <kokey> my car is fully functional now, so I think it's time I order parts
[10:09] <kokey> was thinking of going the MSP430 route but I might just go arduino
[10:10] <Bob_G8NSV> I found a very cheap chinese mini pro duino
[10:11] <kokey> I was thinking of just making a stripduino
[10:11] <kokey> but yeah, maybe a chinese one would safe effort
[10:12] <kokey> or rather, debugging the computer itself

[10:12] <Bob_G8NSV> sorry about the stupid long url!!
[10:13] <Bob_G8NSV> cheap and I have been told that you should be able to run it on 3.3v probably at full speed. If not it should certainly run at 8MHz and you just alter the timing accordingly
[10:15] <kokey> that's cheap
[10:15] <Bob_G8NSV> dont think you could build anything for that
[10:15] <kokey> heh, i first thought the holes are not holes
[10:16] <Bob_G8NSV> very light as well
[10:16] <Bob_G8NSV> 3g
[10:16] <kokey> the ublox and rfm run at 3v too?
[10:16] <Bob_G8NSV> rfm does sure that ublox does
[10:17] <Bob_G8NSV> navrac used a boost converter and 3 aaa's thats my route
[10:17] <Bob_G8NSV> aaa's in parallel
[10:18] <kokey> why aaa's?
[10:18] <kokey> ublox, 3v, cool
[10:19] <kokey> I guess AAA's last more than long enough and are cheap
[10:19] <Bob_G8NSV> it was a pico payload, mine will be a solar pico so need to keep the weight right down on both
[10:19] <Bob_G8NSV> for a non pico use bigger lithiums if you want
[10:20] <Bob_G8NSV> but must be lithium they work at freezing temps

[10:21] <Bob_G8NSV> again bynavrac
[10:22] <Bob_G8NSV> others as well im sure
[10:22] <daveake> Bob_G8NSV: Do you really mean "3 AAAs in parallel"?
[10:22] BrainDamage (~BrainDama@dynamic-adsl-78-12-241-11.clienti.tiscali.it) joined #highaltitude.
[10:23] <Bob_G8NSV> I believe so?
[10:23] jcoxon (~jcoxon@84.3.113.87.dyn.plus.net) left irc: Quit: Leaving
[10:23] <Bob_G8NSV> sure it was 3?
[10:23] <daveake> Series would make more sense
[10:23] <daveake> 3 AAAs in parallel gives you the same capacity as an AA, but heavier
[10:24] <daveake> Also converters aren't efficient (if they even work) at the 1V you'll be getting when the batteries are cold
[10:24] <Bob_G8NSV> sure I read parallel into a boost converter to give the regulated 3.3v
[10:24] <daveake> AA: 3Ah 15g. AAA: 1Ah 7.5g.
[10:24] <Bob_G8NSV> but I could be wrong !!!
[10:25] <kokey> I think I'd rather scout around for batteries made for what were the most commonly used Nokia phones in developing countries
[10:26] <Bob_G8NSV> check their performance at low temps
[10:26] <kokey> they're mostly lithium from what I can see
[10:26] <Bob_G8NSV> a lot of technologies die below freezing and give no voltage, thats why people use lithium
[10:27] <Bob_G8NSV> those shouls work fine then
[10:27] <SpeedEvil> It depends to a degree what load you're drawing.
[10:27] <SpeedEvil> Much stuff will sort-of-work.
[10:27] <daveake> There are many different types of Lithium
[10:28] <SpeedEvil> Plus, if it's got a camera, even if fairly minimally insulated, a couple of watts from the camera tensd to keep the payload over 0Cish
[10:28] <SpeedEvil> ofthn
[10:28] <daveake> Lithium bells that is
[10:28] <daveake> Indeed
[10:28] <daveake> I've not seen below zero on any of my photo payloads
[10:28] <daveake> cells*
[10:28] <kokey> the canon ixus cameras have temp sensors
[10:29] <kokey> actually would have been handy if IO to a canon was straightforward
[10:29] <kokey> the camera could just be the flight computer

[10:36] <Bob_G8NSV> one day the first smart phones with gps and cameras will be obsolete and worth nothing. Stripped out of the cases to lighten them they would make great flight computers, just write code for them, sure you could interface a radio to the usb port
[10:37] <fsphil> our the audio out
[10:37] <Bob_G8NSV> exactly!
[10:37] <fsphil> esp. if you can remove dc filter
[10:37] <fsphil> just make it a straight dac
[10:38] <kokey> yeah smart phones yes
[10:38] <Bob_G8NSV> a bit of micro surgery with a steady hand! there were mods like this to soundcards
[10:38] <Bob_G8NSV> to use them as adc's
[10:38] <kokey> but not feature phones unfortunately, they're hard to hack in any way
[10:38] <Bob_G8NSV> android would be the one I guess
[10:39] <kokey> yeah I guess cheapie android models
[10:39] <kokey> handed around for next to free
[10:39] <Bob_G8NSV> as long as teyhave gps
[10:40] <SpeedEvil> They already are quite inexpensive!
[10:40] <fsphil> though an arm SoC could be an option -- entire flight computer on a chip
[10:40] <Bob_G8NSV> in a few years there will be millions of them floating around cheap
[10:40] <Bob_G8NSV> or free!
[10:40] <kokey> HTC G1 and G2 still goes in the £100 range
[10:40] <SpeedEvil> GPIO is a bitch
[10:41] <kokey> I should have kept my GP2X
[10:41] <Bob_G8NSV> still not as much fun as building your own, even from pre built modules!!

[10:42] <joph> nice but to expensive
[10:42] <kokey> actually, my GP2X, would eat big brand alkaline batteries up in 30 minutes of use
[10:42] <kokey> the best rechargable ones from Maplin, would last 2 hours
[10:42] <kokey> and Ansmann AA rechargeables would go for over 4 hours
[10:42] <fsphil> not all these phones like being in sub zero temperatures too
[10:43] <fsphil> slower microcontrollers seem to be the winner there
[10:43] <kokey> funny I would have thought cold is good
[10:43] <fsphil> yea
[10:43] <kokey> but I guess bad heat distribution could damage chips
[10:43] <fsphil> it's timing issues I think
[10:44] <kokey> ah
[10:44] <kokey> I guess slow ones are slowed down on purpose
[10:44] <SpeedEvil> kokey: PLLs in chips generally need recalibration when temperatures vary.
[10:44] <SpeedEvil> For obvious reasons, most phones are not designed to recal when their temp hits -20C
[10:44] <SpeedEvil> so they crash
[10:44] <kokey> screw liquid cooling your overclocking setup, attach it to a balloon
[10:44] <SpeedEvil> same as gumstix for example
[10:45] <fsphil> and beagleboards
[10:45] <fsphil> as Tim found out
[10:45] <fsphil> twice
[10:45] <kokey> sounds like anything 'beagle' is doomed to fail
[10:45] <daveake> Raspberry Pi next?
[10:45] <fsphil> hah
[10:46] Action: SpeedEvil looks at his Pi.
[10:46] Action: fsphil hides his
[10:46] <daveake> I've looked at mine too
[10:46] <fsphil> it's my precious!
[10:46] <fsphil> at least, until they're available easily then I'll send one up :)
[10:46] <WillDuckworth> gonna send it up fsphil?
[10:46] <fsphil> not this one
[10:46] <fsphil> maybe the next one
[10:47] <daveake> I don't mind sending one up
[10:47] <fsphil> wanna do some narrow band tv
[10:47] <WillDuckworth> go on... you know you want to
[10:47] <fsphil> oh I so want to :)
[10:47] <WillDuckworth> what could possibly go wrong?
[10:47] <fsphil> exactly!
[10:47] <daveake> If I send one up, it on't be alone!
[10:47] <daveake> w
[10:47] <fsphil> I'd like to test the nbtv stuff first though
[10:48] <fsphil> just transmit a test signal from an avr
[10:48] <WillDuckworth> oohh that'd be cool
[10:48] <fsphil> see if anyone can receive it
[10:48] <fsphil> although the software to decode it is windows-only atm
[10:48] <fsphil> that can be fixed
[10:48] <WillDuckworth> what transmitter do you think?
[10:49] <fsphil> ntx2
[10:49] <fsphil> it's an analogue signal, will be received in FM on the ground so will need a good antenna
[10:49] <fsphil> although I'd love to make it work in ssb
[10:51] <Bob_G8NSV> with ssb in the air we could use decent modulation modes like psk
[10:52] <Bob_G8NSV> already in fldigi
[10:52] <fsphil> psk would be nice
[10:52] <Bob_G8NSV> real low level signal stuff
[10:52] <fsphil> we need radiometrix to make an I/Q modulator :)
[10:53] <fsphil> there are ICs out there that do that though
[10:53] <Laurenceb> anyone here used parcelfarce?
[10:53] <fsphil> was some stuff about it in radcom recently
[10:53] <Laurenceb> their tracker just says "forwarded for export"
[10:53] <Laurenceb> is that normal?
[10:54] <Bob_G8NSV> from what i recall yes
[10:54] <Bob_G8NSV> doesent even show movement between depots in the uk

[10:56] <Bob_G8NSV> well im off out to do some shopping before the supermarkets go crazy!!
[10:56] <gonzo_> you could get NBTV (assuming SSTV) ton work in SSB if you fed the NTX2 with the offest as a voltage rather than feeding it audio0 tones
[10:56] <Laurenceb> so basically i just have to wait for it to turn up now?
[10:57] <gonzo_> you could make an NTX2 do PSK.
[10:57] <gonzo_> feed the o.p to a dbm, then a gain stage as a PA
[10:57] <gonzo_> use the dbm as a phase modulator
[10:58] <gonzo_> so just using the NTX2 as an oscillator
[10:58] <fsphil> the nbtv formats dont' work in ssb atm
[10:58] <Laurenceb> you mean a balun?
[10:58] <Laurenceb> yeah
[10:58] <fsphil> they're more similar to regular TV than sstv
[10:58] <gonzo_> or do the same with an rfm2
[10:58] <Laurenceb> and an rf switch?
[10:59] <fsphil> what I'm considering now is just a speeded up sstv I guess
[10:59] <gonzo_> you mean the 30line tv phil?
[10:59] <SpeedEvil> It would be interesting to try to calibrate it to do PSK
[10:59] <fsphil> something like that yea, like the really old mechanical tvs
[10:59] <gonzo_> I was thinking a double balanced modulator/,ixer
[10:59] <SpeedEvil> based on integration
[10:59] <fsphil> gives about 15fps low resolution video
[10:59] <gonzo_> we have a guy at the club been playing with that
[11:00] <fsphil> quite a step down from a gopro, but still neat :)
[11:00] <gonzo_> the NBTV club use 32line as a standard
[11:00] <gonzo_> and you can have a mechanical televisor on the ground for rx
[11:00] <fsphil> hah, that'd be cool
[11:01] <SpeedEvil> With a large wheel spinning at close to mach 1.
[11:01] <fsphil> not terribly portable though :)
[11:01] <fsphil> I'll stick to software decoding for now
[11:01] <gonzo_> just send the level and synxc to the ntx2, and have a pll on the rx to recover the level
[11:01] <SpeedEvil> Boooring.
[11:01] <gonzo_> big but fun
[11:02] <fsphil> won't be colour either, although I see people have done that
[11:02] <gonzo_> some prople have played with mirror drum scanners for cameras. But recon they would be more fun as a projector
[11:02] <gonzo_> frame sequential
[11:02] <gonzo_> why not!
[11:04] <gonzo_> (I can feel a whole raft of new projects coming on here, that I really don't have time for)
[11:04] <fsphil> lol

[15:36] <Lunar_LanderU> Upu: lock was achieved like after 10 seconds or so outdoor
[15:37] <UpuWork> yeah that will do
[15:37] <Lunar_LanderU> next problem then was
[15:37] <Lunar_LanderU> I connected the RX and TX to the UART 1 of my Mega 3.3V
[15:37] <Lunar_LanderU> and also the power pins (VCC and GND) and then I used that example program on arduino.cc that was used yesterday here
[15:37] <Lunar_LanderU> wait
[15:38] <Lunar_LanderU> http://arduino.cc/en/Serial/read
[15:38] <Lunar_LanderU> I used that program, only changed to Serial1, but left the Serial.begin(9600); as I thought that is needed for the connection to the PC
[15:38] <daveake> didn't know there was a 3v3 mega
[15:38] <daveake> useful
[15:39] <Lunar_LanderU> now the serial monitor races and shows lines like "I received: 41"
[15:39] <Lunar_LanderU> any ideas on that?
[15:40] <UpuWork> If I'm being honest I'm not really sure what you're about about
[15:40] <UpuWork> your trying to echo the GPS to the Software serial ?
[15:41] <Lunar_LanderU> ok, the setup is as follows
[15:42] <Lunar_LanderU> I have the 3.3V to VCC on the GPS, GND to GND, GPS TX and RX to Arduino UART 1
[15:42] <Lunar_LanderU> and I would like to be able to see the NMEA in the Serial Monitor
[15:42] <Lunar_LanderU> can it be that the current from the 3.3V pin is not sufficient?

[15:43] <Lunar_LanderU> I also got my 2.7V 6 Ah lipoly but that could be too little voltage?
[15:43] <daveake> Also, this "I received 41". Is that hex/decimal/what?
[15:43] <Lunar_LanderU> I have no idea
[15:43] <daveake> yes
[15:43] <Lunar_LanderU> the number changes all the time
[15:43] <daveake> Well that sounds positive
[15:44] <Lunar_LanderU> ah
[15:44] <daveake> what's the code to print it?

[15:44] <Lunar_LanderU> daveake: one sec
[15:45] <daveake> If your code is sending "I received xx" when it sees xx, and your GPS is working, you're going to see gazillions of those lines
[15:45] <UpuWork> lol
[15:45] <UpuWork> yeah
[15:46] <daveake> You're better of just printing the character as ascii
[15:46] <daveake> off
[15:46] <Lunar_LanderU> http://paste.ubuntu.com/1018114/
[15:46] <daveake> If you're printing it in hex or decimal see http://www.asciitable.com/
[15:47] <daveake> int incomingByte = 0; should be char ...
[15:47] <nigelvh> Just change the two lines in the say what you got section to Serial.print((char)incomingByte);
[15:47] <daveake> And you're printing the decimal version (That's what DEC does)
[15:47] <UpuWork> I thought it would be quiet this afternoon, everyone getting off early but its mental here
[15:48] <daveake> 41 is ")" which seems a bit strange for nmea
[15:48] <zyp> 41 hex is B IIRC
[15:48] <daveake> Yeah but his code says DEC
[15:49] <daveake> And you mean A :)
[15:49] <zyp> yes, I didn't recall correctly
[15:49] <Lunar_LanderU> XD
[15:49] <Lunar_LanderU> OK wait

[15:50] <daveake> I think I spent too much time staring at ascii tables :p
[15:50] <nigelvh> No
[15:51] <nigelvh> You'll end up with each char on a new line
[15:51] <daveake> Do what nigelvh said ^^ a few lines
[15:51] <nigelvh> If you want a mirror of what's coming through, just remove both those two lines, and put in Serial.print((char)incomingByte);
[15:51] <zyp> nigelvh, that won't work
[15:52] <nigelvh> Why
[15:52] <zyp> or is print() overloaded to take both strings and individual chars?
[15:52] <nigelvh> It handles either
[15:52] <daveake> Yep. Arduino is special.
[15:52] <zyp> ah, right

[15:56] <nigelvh> Lunar_LanderU, in realtity, you could shorten things up a bit, but that code should serve the function.
[15:56] <daveake> Yep
[15:56] <daveake> 1 - incomingByte might as well be a local
[15:57] <daveake> 2 - you don't need to init incomingByte
[15:57] <nigelvh> might as well not have incomingByte
[15:57] <daveake> that was 3 :)
[15:57] <nigelvh> My good timing then.
[15:57] <Lunar_LanderU> XD
[15:57] <daveake> lol
[15:57] <Lunar_LanderU> btw I got a friend also discussing the code here
[15:57] <Lunar_LanderU> (female)
[15:58] <nigelvh> I would just replace everything in the if statement with this: Serial.print((char)Serial1.read());
[15:58] <nigelvh> But that's just my preference. Your code should work.
[15:59] <Lunar_LanderU> ah ok
[15:59] <Lunar_LanderU> thanks
[16:00] <Lunar_LanderU> and I got a female interested in HAB
[16:00] <Lunar_LanderU> XD
[16:00] <nigelvh> Catch her boy. Don't let her get away
[16:00] <daveake> lol
[16:00] <daveake> Yeah she's a keeper
[16:01] <kokey> gosh more pony payloads
[16:01] <nigelvh> Pony payloads aren't the worst thing I can imagine.
[16:01] <nigelvh> Frankly if it means more girls in the hobby, I'm all for pony payloads
[16:02] <Lunar_LanderU> XD
[16:02] <kokey> just as I thought HABing is a way for me to get away from women
[16:03] <nigelvh> Well, if you tie YOURSELF to the balloon you'd have a chance to get away.
[16:03] <daveake> It's good at parting from your money
[16:03] <kokey> looks cheaper than my other hobbies, especially the ones that involve women
[16:03] <kokey> ok, off to the pub
[16:04] <kokey> the the motorway
[16:04] <nigelvh> Women tend not to be cheap. Especially when you buy them a ring like I was stupid enough to do for mine.

[16:20] <daveake> :D
[16:20] <daveake> Interesting the way the main ones open so slowly
[16:21] <jdtanner> I thought that as well&maybe it is deliberate?
[16:21] <daveake> I think so
[16:22] <jdtanner> Also, I couldn't really see any form of buoyancy like the old Apollo capsules used to have.
[16:23] <daveake> That was to keep it upright, I guess. Not needed for this one as nobody on board.
[16:23] <jdtanner> True&still I guess they had to be pretty sure that I wasn't going to sink on landing if it had been damaged during reentry
[16:23] <daveake> Yep
[16:23] <jdtanner> I think the sea is pretty deep there...

[19:12] <jdtanner> daveake: brill video :)
[19:12] <daveake> only in Oz :)
[19:15] <jdtanner> I remember seeing a scout leader in the last pour some into a mug, the mug shattered, but was stuck in a vaguely exploded shape in the foam matrix&horrid stuff :0
[19:15] <jdtanner> I love the fact that the use of an extremely toxic chemical is ok to fill holes in the outback :/
[19:24] <G0DJA> Used to use similar stuff to add boyancy to old glass fibre canoes
[19:25] <G0DJA> Horrible stuff and people mixed it inside huts!
[19:35] <jdtanner> No sure if anyone is around&but if I do a Serial.read() on the serial pin to which my UBlox is connected&should the <CR><LF> after the checksum in the NMEA string be read as well, and preserved if I then so a Serial.print() to the arduino serial monitor? I'm having to put in an extra Serial.println("") statement at the end of every NMEA sentence to get it to print on alternate lines.
[19:37] <jonsowman> jdtanner: so it's otherwise just printing all on one line?
[19:37] <jonsowman> with no linebreaks at all?
[19:39] <jdtanner> Yes, exactly
[19:39] <nigelvh> Perhaps try a Serial.write() instead of Serial.print()
[19:40] <jonsowman> yeah it should copy the \n
[19:40] <jonsowman> \r\n actually
[19:40] <jdtanner> It doesn't actually matter really&just wondering why it was missing :)
[19:41] <jonsowman> it might be print doing something clever
[19:41] <jonsowman> or at least what it considers clever
[19:41] <jdtanner> write does the same as print&just one long stream
[19:42] <nigelvh> Then are you sure the characters are being received?
[19:42] <jdtanner> incomingByte = gps.read(); with the variable defined as a char
[19:43] <jonsowman> jdtanner: so you could change print() to println()
[19:43] <jonsowman> but that's not really answering the question
[19:43] <nigelvh> That would put each char on a new line
[19:43] <jdtanner> it also prints each letter on a new line :)
[19:43] <jonsowman> oh i forgot it's sending char by char
[19:43] <jonsowman> ignore me
[19:43] <jdtanner> :)
[19:44] <nigelvh> jdtanner, every time I've done that, the new line chars come through fine. So I would make sure they're being recieved.
[19:44] <jdtanner> nigelvh: not sure what you mean by that
[19:44] <nigelvh> If the arduino isn't getting the chars, it's not going to send them.
[19:45] <jonsowman> jdtanner: if you do print(my_char, DEC)
[19:45] <jonsowman> it will print the decimal values of the character
[19:45] <jonsowman> you can then check if it ends with 13, 10
[19:45] <daveake> yes, try that
[19:45] <jdtanner> cheers
[19:45] <nigelvh> If that's there, then try a different serial terminal. Perhaps the arduino serial console is ignoring those chars.
[19:46] <daveake> Is this "GPS Rx Issues" week? :p
[19:47] <jonsowman> sponsored by Falcom
[19:47] <jdtanner> Pfft&I'm trying to do this when I'm knackered&not a good idea
[19:47] <daveake> Or by Lassen, the NME of rapid locks
[19:54] <jdtanner> Looks like they aren't being sent
[19:54] <nigelvh> That would explain your issue then.
[19:55] <jdtanner> I wonder how far I can throw this gps?
[19:55] <jdtanner> ;)
[19:55] <nigelvh> The GPS could tell you.
[19:56] <jonsowman> hmm
[19:56] <fsphil> unless you throw it too fast
[19:56] <jonsowman> odd
[19:56] <jdtanner> yeah&very odd
[19:56] <jonsowman> nmea should definitely be \r\n terminated
[19:56] <fsphil> yea
[19:56] <fsphil> I've never seen it not
[19:56] <nigelvh> Neither have I
[19:56] <jonsowman> if there's one thing to be said for nmea, it's that it's well defined
[19:56] <fsphil> is the code basically an in->out loop?
[19:56] <jonsowman> mostly
[19:57] <fsphil> in nmea, nobody can hear you newline
[19:57] <jonsowman> it's just a busy wait until a char appears in the uart rx buffer
[19:57] <jonsowman> prints it to terminal
[19:57] <jonsowman> repeat
[19:57] <fsphil> werry odd

[19:59] <fsphil> if the newlines are delayed at all
[19:59] <fsphil> that loop may end before they are sent
[19:59] <nigelvh> Exactly my thought
[19:59] <nigelvh> Or, if they're beyond the length of the buffer before it's read.
[20:00] <nigelvh> I don't recall what the softserial buffer length is...
[20:00] gonzo_mob (~gonzo_mob@31.90.138.227) joined #highaltitude.
[20:00] <jonsowman> does softwareserial use a ring buffer?
[20:01] <fsphil> yea, if the output is the same speed as the input, and you're printing more than one character for each received it will eventually fill
[20:01] <jonsowman> yeah jdtanner, you can happily use 115200 on the arduino-serial link
[20:01] <nigelvh> That shouldn't be the issue though
[20:01] <jonsowman> no
[20:02] <fsphil> try looping until you see the newline character
[20:02] <nick_> Could anyone suggest a good place to buy a (micro) SD card breakout board?
[20:02] <nigelvh> I'd make that loop longer
[20:02] <jdtanner> ok, I'l try lookig for the newline and looking making it longer
[20:02] <fsphil> I got a good full-sized one of sparkfun, but that doesn't help you at all so yea....

[20:05] <nigelvh> I accidentally threw that in there.
[20:05] <daveake> NSS has a 64 byte buffer doesn't it?
[20:06] <nigelvh> That should ensure the loop doesn't end before the string is done being sent.
[20:06] <jdtanner> great, thanks
[20:06] <nigelvh> Assuming it can send the whole data in two seconds, which it should.

[20:07] <r2x0t> it may be better to loop until you don't get any new character for X ms
[20:08] <r2x0t> usually GPS will output everything in ~400ms after second, then send nothing
[20:08] <fsphil> good thinking
[20:08] <fsphil> or loop until nothing, or a newline
[20:09] <r2x0t> just put the "timer = millis() + 200;" inside gpd.avail condition and change it above as well
[20:09] <fsphil> I need to do proper timeout code for swift some of these days
[20:09] <r2x0t> so it waits 200ms after last character

[21:34] <jdtanner> yep&how did you guess?
[21:34] <jdtanner> ;)
[21:34] <fsphil> lol
[21:34] <Upu> out of interest which version of Arduino are you on ?
[21:34] <jdtanner> 1.0
[21:35] <Upu> I couldn't get it working reliably @ 9600 on SS
[21:35] <Upu> http://ava.upuaut.net/store/wiki/doku.php?id=levelconvertor
[21:35] <daveake> [22:33] <jdtanner> just making that change now&I've realised that each line is truncated at 64 characters
[21:35] <daveake> [21:05] <daveake> NSS has a 64 byte buffer doesn't it?
[21:35] <daveake> He shoots he scores :p
[21:35] <Upu> :)
[21:35] <Upu> switch the module to 4800 and its sort of ok
[21:35] <jdtanner> "sort of" love it :D
[21:36] <jonsowman> daveake: you should be emptying the buffer as fast as you fill it though
[21:36] <Upu> being blunt its still sh?t and doesn't work right
[21:36] <Upu> just use hardware
[21:36] <jonsowman> or faster
[21:36] <daveake> jonsowman: Indeed
[21:37] <jonsowman> is it configured as a ring buffer? or fifo?
[21:37] <daveake> Dunno. Don't use it, except for sending to a phone
[21:37] <jdtanner> I've only got one hw serial on the pro mini
[21:37] <Upu> yeah but you can connect the GPS to those
[21:37] <daveake> yup
[21:38] <Upu> and then use SoftwareSerial for the debugging output
[21:38] <Upu> which works fine
[21:38] <jdtanner> Never thought of that :)
[21:38] <jdtanner> I'm a plank&sometimes I wonder how I continue to breathe without assistance
[21:38] <Upu> don't even think you have to disconnect the GPS to program the chip but I may be wrong, daveake ?

[21:38] <jonsowman> without resistors it'd be bad practice
[21:39] <jonsowman> you'd be driving the GPS TX pin which will be in an output state and low impedance
[21:39] <Upu> http://www.billporter.info/how-to-add-multiple-uart-connections/
[21:39] <Upu> I remember now you linked me this jonsowman
[21:39] <jonsowman> Upu: yeah, if you do that, it's fine
[21:39] <jonsowman> :)
[21:39] <Upu> there you go jdtanner :)
[21:40] <jdtanner> brill, thanks all again&time for a beer I think :)
[21:40] <Upu> a good call
[21:40] <jdtanner> Hit my first 5km tonight so I deserve it :D
[21:40] <Upu> running ?
[21:40] <jdtanner> Yep...
[21:40] <Upu> ouch
[21:40] <Upu> I'll stick to walking
[21:41] <jdtanner> I've been doing a thing called C25K
[21:41] <jdtanner> couch to 5km
[21:41] <jdtanner> :)
[21:41] <Upu> well whatever keeps you fit
[21:42] <jdtanner> actually pretty good&free app for the iphone and a good support website :) It means I get out the house&and don't smash gps modules on the kitchen floor when I can't get them to work :p
[21:42] <jonsowman> lol
[21:42] <Upu> Just get a dog :)
[21:42] <daveake> Upu - yes you need to disconnect the GPS to program. There's a resistor trick so you don't have to. I tried that bit it didn't work for me.
[21:42] <jdtanner> I've got one&he is a lazy sod
[21:42] <Upu> I'll just stick to programming via ICSP
[21:42] <jdtanner> :)
[21:43] <daveake> :)
[21:43] <Upu> get him outside :)
[21:43] <jdtanner> He likes outside&just with the missus&not me
[21:44] <jdtanner> fickle little so and so
[21:45] <jdtanner> So, little update&upping the buffer to 128 in SoftwareSerial.h works fine
[21:45] <Upu> interesting I might try that
[21:45] <daveake> Attach tracker to dog; open door; push out dog; close door; watch spacenear. Sorted.
[21:45] <jonsowman> that's like 1/16th of your RAM gone
[21:45] <jonsowman> :P
[21:45] <Upu> lol
[21:45] <jdtanner> https://sites.google.com/site/wayneholder/self-driving-rc-car/navigating-with-gps
[21:45] <jdtanner> Yeah, but it is only for debugging ;)
[21:46] <jdtanner> daveake: good idea ;)
[21:46] <jonsowman> lol i'm kidding, the rest of the software won't use much anyway
[21:46] <jdtanner> You haven't seen my coding
[21:46] <jdtanner> :D
[21:46] <Upu> or mine..
[21:46] <jonsowman> just don't store strings in RAM
[21:46] <jdtanner> I tend to keep them in a bag in a drawer
[21:46] <jonsowman> http://arduino.cc/en/Reference/PROGMEM
[21:46] <jonsowman> use that ^ for fixed strings
[21:47] <jonsowman> such as the format string in printf
[21:47] <jdtanner> ooh, cool, thanks
[21:47] <jonsowman> it keeps them in ROM/flash instead
[21:47] <jonsowman> which is better
[21:47] <jdtanner> bookmarked
[21:48] <jonsowman> anyway yeah don't worry about it for now
[21:50] <jdtanner> I've just used it actually :)
[21:51] <jonsowman> :)

[21:51] <jdtanner> In for a penny as they say
[21:51] <jonsowman> yep
[21:51] <jonsowman> you don't want to run short of RAM
[21:51] <jonsowman> it causes weird problems
[21:51] <jdtanner> again&you haven't seen my code :P
[21:52] <jonsowman> hehe
[21:52] <jonsowman> is it open source?
[21:53] <jdtanner> I don't really believe in any other type when it comes to hobby projects like this :)
[21:53] <jonsowman> that's what i like to hear lol
[21:54] <jonsowman> is it hosted anywhere?
[21:54] <jonsowman> github or something
[21:54] <jdtanner> my laptop at the moment&I have a github account&but never really used it
[21:55] <jonsowman> it's worth making it available, people on here will have a glance at it for you
[21:56] <jonsowman> anyway yeah, use version control
[21:56] <jonsowman> :P
[21:56] <jdtanner> As soon as I've got my GPS code in a nice state, I'll get my code up on github&I have the RTTY element of my code pretty much complete :)
[21:56] <jdtanner> Yeah, that is a very good point

[21:58] <jdtanner> I'll have a look at github in a wee while
[21:59] <jonsowman> you'll thank yourself later
[21:59] <jonsowman> when the code gets more complex and something breaks
[22:01] DoNcK (~jverdonc@pat35-3-82-245-143-37.fbx.proxad.net) left irc: Quit: Leaving.
[22:02] <jdtanner> yes, at the moment it is small enough to just rely on comments&he said
[22:02] <jonsowman> haha
[22:03] <jdtanner> I'm amazed that I'm getting a GPS fix in my house&good little gps Upu
[22:03] <jonsowman> they are surprisingly good
[22:04] <jonsowman> sensitivity is astonishing
[22:04] <jdtanner> The walls of my house are 3ft thick at the narrowest!
[22:08] <fsphil> you live in a castle?
[22:09] <jdtanner> haha&I wish :)
[22:09] <jdtanner> I think they built them this way because they haven't got any foundations :D
[22:10] LazyLeopard (~irc-clien@chocky.demon.co.uk) left irc: Quit: Bye
[22:10] <Upu> you have the Sarantel version jdtanner ?

[22:12] <jdtanner> Erm, not sure Upu&whatever you sold me :D
[22:13] <Upu> has it got a black plastic cap ?
[22:13] OZ1SKY_Brian (~Brian@x1-6-20-4e-7f-c8-44-7a.k599.webspeed.dk) left irc: Read error: Connection reset by peer
[22:13] <jdtanner> Yep&lose black cap
[22:13] <daveake> Those do work incredibly well
[22:13] <jonsowman> sarantel SL something
[22:14] <jonsowman> Upu: are they the new ones with the PCB mount instead of th pins now?
[22:14] <Upu> yes appearently but I've yet to have some samples
[22:14] <Upu> they are suppose to be sending me some
[22:14] <jonsowman> me too
[22:14] <Upu> I just keep buying the ones with pins
[22:14] <jonsowman> not heard anything
[22:14] <Upu> I had a quick chat with them 2 weeks ago
[22:14] <Upu> as I needed to order some new PCB's
[22:15] <jonsowman> oh okay, what did they say?
[22:15] <Upu> non committal
[22:15] <jonsowman> heh
[22:15] <Upu> they said they would continue to make the SL-1202 for a "while"
[22:15] <Upu> So I got 50 PCB's made up
[22:15] <jonsowman> fair enough
[22:16] <jonsowman> they're not bad, but the 1252 or whatever should be better
[22:16] <Upu> Though RS took 2 months to deliver the last lot
[22:16] <Upu> I might order another 25 just in case
[22:16] <Upu> Yeah hopefully they will be stronger too
[22:16] <jonsowman> hope so
[22:18] <Upu> and hopefully I won't have to send 3-4 back each order because they are bent badly
[22:18] <jonsowman> that's pretty bad
[22:18] <jonsowman> do they replace them?
[22:18] <Upu> yeah
[22:19] <jonsowman> hmm well OK
[22:19] <jonsowman> by the way
[22:19] <jonsowman> did you get a reply from euroquartz?
[22:19] <Upu> oddly they keep sending some packets with 2 antennas in and one Radome
[22:19] <Upu> but no holder
[22:19] <jonsowman> :\
[22:19] <Upu> no I meant to call them today
[22:19] <Upu> didn't get time it was annoyingly busy
[22:19] <jonsowman> ah okay
[22:19] <Upu> bit odd
[22:19] <jonsowman> yeah they replied very quuickly to me
[22:20] <jonsowman> i got an email today saying the crystals have been manufactured and are now in testing
[22:20] <Upu> "hello I want to give you some money ?"
[22:20] <jonsowman> yeah you would've thought they'd be keen
[22:20] <Upu> I'm very interested to see if we can stabalise the NTX2 and adjust its frequency
[22:21] <jonsowman> me too
[22:22] <Upu> I'll give them a call next week
[22:35] <fsphil> would be a huge gain if we could stabilise it
[22:35] <fsphil> makes a lot of these more exotic modes possible
[22:36] <Upu> I'll let you know
