[00:24] <Randomskk> wow
[00:24] <Randomskk> way to miss the point?
[00:24] <Randomskk> the fact that it has a transmitter/generator is like this tiny addendum
[00:24] <Randomskk> the whole glorious thing about this is that it can generate signals too!
[00:25] <SpeedEvil> :-)
[00:28] <craag> fsphil: Just wanted to say thank you for your help today, we eventually ditched the camera as we couldn't get a raw image out of it even.
[00:28] <fsphil> aah shame
[00:28] <fsphil> what was it?
[00:30] <craag> It was a chinese clone of an OV7670 with a FIFO. They were lying around at the Uni, hence us trying to use them.
[00:30] <mattbrejza> are those the ones they used for D4?
[00:32] <craag> yes.....
[00:33] <craag> :P
[00:33] <mattbrejza> i heard noone actually got them working
[00:33] <craag> One person has, as part of his 3YP, and lent us his.
[00:33] <craag> But we couldn't get the mbed to talk to it properly.
[00:33] <mattbrejza> ah at least sometnig to start from
[00:34] <mattbrejza> was this a mbed sponsored competition?
[00:34] <craag> Plus we were under strict instructions not to lose it... so wouldn't have been able to fly it anyway!
[00:34] <craag> Erm, I think so.
[00:34] <fsphil> if it's anything like the c328 then it's very fussy about baud rates and timings
[00:34] <mattbrejza> there must have been spares around

[00:35] <mattbrejza> ah, noone is around on sundays also
[00:35] <mattbrejza> or lunchtimes
[00:35] <mattbrejza> or mornings
[00:35] <fsphil> mornings.. nasty things
[00:36] <mattbrejza> actually some people are sharp in the morning due to getting their parking spot
[00:36] <mattbrejza> however theyre never the ones you want to talk to
[00:37] <mattbrejza> i was thinking of working 8-6 next week and taking firday off
[00:38] <mattbrejza> not sure how long that will last
[00:38] <Randomskk> would anything stop you working 9-5 and also taking friday off?
[00:38] <fsphil> yea I was reading about those kind of hours
[00:38] <Randomskk> bbc had an article recently I think?
[00:38] <fsphil> yea
[00:39] <mattbrejza> i might have got the idea from thta article
[00:39] <mattbrejza> and no i could "work from home" the entire week
[00:39] <fsphil> we do 8-5, and get half day friday. which is nice
[00:39] <Randomskk> when I was a research student (heady days) there was a week when all my supervisors were on holiday and I interacted with zero other people all day
[00:39] <mattbrejza> being chinese new year soon the lab is gonna be empty
[00:39] <Randomskk> working hours became kinda entertaining
[00:39] <Randomskk> like 11-3 or something, with a generous lunch break
[00:40] <Randomskk> didn't really help though. just worked on my stuff once I got home. hate having interesting work.
[00:40] <fsphil> I wish I had interesting work
[00:40] <griffonbot> Received email: Philip Crump "[UKHAS] Pico Launch Announcement: VERTIGO"
[00:40] <Randomskk> hehe
[00:41] <Randomskk> yea I don't hate it really ;)
[00:43] <mattbrejza> i hope craag isnt intending to drive ^
[00:44] <craag> I'm sleeping now. Payload just needs to be re-programmed and put in the box. I do have someone on standby if I don't feel up to it.
[00:45] <Randomskk> hehe
[00:45] <craag> *About to sleep now.
[00:45] <Randomskk> power through! it's only 0045!
[00:45] <MrCraig> Mountain Dew helps o.O
[00:45] <Randomskk> I've had a couple of morning hab launches that didn't see any sleep a good while beforehand :P
[00:46] <fsphil> that's most of mine too
[00:46] Action: mfa298 wonders if thats the shortest notice announcment yet
[00:46] <fsphil> I announced one after I launched?
[00:47] <mfa298> i think you win then
[00:47] <fsphil> I wasn't sure if it was going up, so I thought I'd leave it until later
[00:47] <fsphil> only got time to do it on the way home after launch
[00:47] <fsphil> and then the transmitter failed after I announced it
[00:49] Action: mfa298 makes a note to pack redbull/coffee I have a feeling craag might need caffiene.
[00:51] <mattbrejza> btw craag any reason for launching by winchester? could just launch from campus, 6.30 being before the airport is open
[00:52] <mfa298> I think its mostly down to predictions.
[00:52] <mattbrejza> also thers stuff in the way potentionally i suppose
[00:53] <mfa298> launch from soton would be a wet landing
[00:53] <fsphil> is this a foil balloon or latex?
[00:53] <mfa298> pretty sure its foil

[07:18] <craag> It'
[07:18] <craag> its an mbed
[07:19] <craag> 868 has gone, don't know why.
[07:20] <arko> hmm
[07:20] <arko> i've never had an mcu that noisy
[07:20] <arko> where it knocks out gps
[07:20] <craag> well it couldn't get a lock in the middle of an open field
[07:21] <craag> we moved it and it works
[07:25] <x-f> good luck with the flight
[07:25] <arko> wow crazy

[07:34] <G8KNN-Jon> OK, thanks, 8n1?
[07:34] <craag> Telemetry will be very intermittent, 868 is switched off for some reason, but the mcu thinks its on, so just position every 40 seconds or so on 434

[07:58] <mrShrimp> in the amateur community that is.
[08:05] <RocketBoy> made one once http://imagebin.org/245308
[08:06] <mrShrimp> How did it go? It looks like a sound construction.
[08:09] <RocketBoy> got a clip of the launch somewhere - struggling to find it
[08:10] <arko> the climb looks really really slow
[08:11] <craag> what's the current ascent rate?
[08:11] <mrShrimp> 0.3 m/s
[08:11] <craag> ouch
[08:11] <craag> :(
[08:11] <mrShrimp> This is VERTIGO, yes?

[08:13] Nick change: craag -> craag_M0DNY
[08:13] <mfa298> the lack of updates might be down to wifi and tracking pc being in different cars

[08:20] <cm13g09> need somebody Crawley way to try and pick it up
[08:20] <cm13g09> or Guildford at the moment
[08:20] <craag_M0DNY> carrier has disappeared here.
[08:20] <cm13g09> Graeme and I would chase.... but he's asleep
[08:21] <cm13g09> and I have no car rig
[08:24] <cm13g09> it appears to be heading down

[08:24] <arko> 0.0 climb
[08:24] <cm13g09> was -0.2
[08:24] <arko> hopefully it lands so you can recover

[09:05] <Upu> be some interesting pictures if it was taking any
[09:06] <Upu> underfilled as well I think
[09:07] <RocketBoy> yeah thats what got me thinking with such a low ascent rate
[09:08] <RocketBoy> trouble is the cloud will drift along with it

[09:44] <cm13g09> depending on the route it took....
[09:44] <cm13g09> it may have turned up somewhere where I know the people there

[09:51] <jcoxon> for once my antenna is well placed
[09:52] <Upu> 434.248 shift 450
[09:52] <Upu> WAS LAST

[09:53] <mfa298> might be worth tuning +/- 10khz as I had it around .257 before launch
[09:53] <mfa298> but had real problems recieving it on the 817 :S
[09:54] <GMT> the only person who seems to have received it is M0DNY

[09:55] <craag> Yep, with a funcube pro plus
[09:55] <GMT> my SDR wayetfall is showing 433.5 to 435.5, and it's not visible in that range
[09:55] <GMT> wayetfall! = waterfall
[09:55] <craag> mfa298 didn't manage to receive it at the launch site with an ft-817 or handheld.
[09:55] <mfa298> something weird was happening with the with recieving it on the 817 i could hear it but there was something making it come and go at around 1Hz
[09:55] <jcoxon> nah nothing for me
[09:56] <jcoxon> mfa298, sometimes the GPS can do that
[09:57] <mfa298> i did find the gps on my laptop was adding noise later on but I'm not sure if it was enough to affect it. Had the same when I moved the 817 away from everything else.
[09:57] <GMT> there's a regular pulsing type sig on 434.2375, but nothing like a decodable signal

[14:26] domlin (57707863@gateway/web/freenode/ip. joined #highaltitude.
[14:27] <fsphil> better grounding
[14:27] <Hix> ah ok
[14:30] <Hix> asume it just connects the top and bottom ground planes in addition to the used vias?
[14:33] <Randomskk> "just"
[14:33] <Randomskk> but yes
[14:33] <fsphil> yea. I'm not sure of the physics, but I assume it reduces the resistance between the two planes
[14:33] <Randomskk> those vias are essentially all to make sure ground is low-impedance everywhere
[14:33] <Randomskk> basically it acts as many more wires in parallel to connect the two grounds
[14:33] <Randomskk> which reduces the resistance to the main grounding point from any given location on the board
[14:33] <Randomskk> which means the voltage drop caused by current flowing to ground is smaller
[14:34] <Randomskk> which means the ground is closer to the same voltage everywhere
[14:34] <Randomskk> which reduces noise, improves range, reduces emi, other good things
[14:34] gb73d (gb73d@88-110-51-131.dynamic.dsl.as9105.com) joined #highaltitude.
[14:34] <Hix> cleared that up nicely then :)
[14:34] <fsphil> does it buy me a puppy?
[14:35] <Randomskk> only if you use enough vias
[14:35] <fsphil> I had awful problems with grounding on one of my old nestboxes -- three cameras, lights and microphones
[14:35] <fsphil> the lights caused all sorts of noise to the cameras, and two of the cameras would interfere with eachother
[14:35] <fsphil> I believe all that was because of bad grounding
[14:36] <Randomskk> yea grounding is both very important and also a bit obscure at first
[14:36] Action: Hix adds vias
[14:36] <Randomskk> because on your schematic it's just "ground"
[14:36] <Randomskk> real life is more annoying
[14:37] <fsphil> also didn't help that this system was at the end of a 10m cat5 cable
[14:37] <Randomskk> if you start modelling every piece of copper as a resistor and bear in mind the currents going through them it gets better
[14:37] <Randomskk> but you also have to consider the fact that the currents are not DC
[14:37] <Randomskk> as in, they will start, and stop, and change depending on what stuff's doing
[14:37] <Randomskk> and that means they have some frequency component, which means impedance becomes an issue
[14:38] <Randomskk> which means on a PCB with a ground plane that has a hole in it, the current has to go around the hole, deviating from the lowest impedance route
[14:38] <Randomskk> which causes emi issues and stuff
[14:39] <fsphil> could an oscillator be constructed from bare copper on a pcb? since tracks are both inductors, capacitors and resistors in some measure
[14:39] <fsphil> -both
[14:40] <Randomskk> I suppose so, yes
[14:40] <Randomskk> but it'd have such a low Q
[14:40] <Randomskk> trace inductors are relatively common things
[14:40] <Randomskk> but capacitors are somewhat rarer. except power planes.
[14:40] <Randomskk> the area you need for effective capacitance is somewhat limiting
[14:41] <mattbrejza> use s 16 layer boards with alternate layering
[14:41] <fsphil> my pondering was about having a transmitter and an antenna all in bare copper on a pcb
[14:41] <fsphil> since you could make a yagi on a pcb quite easily
[14:41] <Randomskk> 4 layer boards will typically have a ground plane and a power plane and so the two of them make the whole PCB a capacitor
[14:41] <mattbrejza> might get a decent(ish) capacitance then :P
[14:41] <Randomskk> but that's huge compared to the inductor
[14:41] domlin (57707863@gateway/web/freenode/ip. left irc: Ping timeout: 245 seconds
[14:41] <Randomskk> and much better to just stick a capacitor on
[14:41] <Randomskk> yagi on pcb is possible and common for some wifi applications
[14:41] <Randomskk> harder for 434MHz :P
[14:41] <fsphil> well yes
[14:42] <Randomskk> it'd be cool
[14:42] <Randomskk> probably not super practical :P
[14:42] <Randomskk> right I'd better run. bbl.
[14:42] Action: Hix thinks Randomskk is just guessing at all this ;p
[14:43] <Randomskk> haha radio is all just black magic and guesswork
[14:43] <mattbrejza> ive seen inductor on pcb
[14:43] <mattbrejza> and ive read the nF/m^2 figure for pcb
[14:43] <Randomskk> but fwiw I have done modules in rf engineering as part of my masters course >_>

[14:43] <Randomskk> "expert candidate" maybe :P

[14:45] <mattbrejza> that would have been a couple of modules this year

[14:45] <Randomskk> we did do PCB inductors and antennas though

[15:53] <chrisstubbs> got my sound card working with dlfldigi on the pi now, but i see what was menat about it not quite being fast enough to show the waterfall and decode...
[15:54] <chrisstubbs> can i disable the waterfall completley, or am i going to have to overclock the pi to 1.2ghz?
[15:54] <fsphil> my evil plan (which may never get done) was to port fldigi to work on the framebuffer or console
[15:55] <fsphil> weirdly even disabling the waterfall doesn't help
[15:55] <chrisstubbs> hm
[15:55] <fsphil> well it can be paused
[15:55] <chrisstubbs> yeah using the framebuffer should help
[15:55] NickSF (~NickSF@ left irc: Ping timeout: 252 seconds
[15:56] <fsphil> would be interesting to run it through a profiler, see where it's spending all its cycles

[15:56] <chrisstubbs> got it all running in front of me
[15:59] <fsphil> what distro are you using out of curiosity?
[15:59] <chrisstubbs> raspbian
[15:59] <mfa298> one of my many plans is to learn about coding on a gpu to see what might be possible on the pi
[16:00] <fsphil> would be awsome if you could offload all the maths
[16:00] <mfa298> one of these days I might get around to it.
[16:00] <chrisstubbs> wish i was a little more into linux for things like this, yea it would speed things up a lot!
[16:00] <mfa298> I'm thinking it could be interesting both for fldigi and for the rtl-sdr
[16:01] <chrisstubbs> do you think it would be powerful enough to run both? using the GPU?
[16:02] <mfa298> I'm not sure yet. might be nice if it can although that might be asking a bit much
[16:02] NickSF (~NickSF@ joined #highaltitude.
[16:02] <chrisstubbs> maybe, but if it did it would be a fantastic acheivment
[16:03] <fsphil> it might be simpler to write a new program than get fldigi working with the pi gpu :)
[16:04] <chrisstubbs> might be easier to just carry on using my netbook sitting on top of my radio for fldigi haha
[16:04] <mfa298> that might be true.
[16:05] <fsphil> yea but that's not Pi
[16:05] <fsphil> you must have Raspberry involved or it's not cool

[16:28] <Hix> wonder what the range is with a 2.4GHz downlink is in clear air from alt
[16:28] Action: Hix hatches a stupid plan
[16:32] <mfa298> I think someone did some calcs on losses for 2.4Ghz a while back. I think the result might have been theoretically possible although 2-way comms might get interesting.

[16:34] <mattbrejza> those 2.4GHz things are only 10dBm?
[16:35] <mfa298> I've got a feeling non wifi 2.4Ghz was fairly low power.
[16:35] <mfa298> you might be able to fly wifi but then you need 2 way comms which could be fun.

[16:45] <Lunar_Lander> hello
[16:45] <daveake> Reading that CAP722 document linked to at the bottom. It says ... "An approved method of aerial collision avoidance is required and, therefore, UAS
[16:45] <daveake> operations will not be permitted in the United Kingdom in non-segregated airspace,
[16:45] <daveake> outside the direct unaided visual line-of-sight of the pilot, without an acceptable

[16:46] <daveake> So that would be the line-of-sight thing I read somewhere else
[16:46] <daveake> And Hix, sorry but it then says "The use of 'First Person View R/C' equipment (see CAP 658) is not
[16:46] <daveake> considered to be acceptable for use as a Detect and Avoid solution"

[16:50] <Hix> so it could be possible in "segregated airspace"
[16:52] <gonzo_> how about a HAB beacon on the plane and watching ASD-B, than making sure the two stay apart?
[16:53] <gonzo_> if 2ndry radar is considered 'approved' method
[16:55] <mfa298> reading ir2030 wireless cameras are limited to 10mW on 2.4Ghz (airborne and ground)
[16:56] <mfa298> so those 1W units probably wouldn't even be allowed on the ground
[17:00] <Lunar_Lander> what's the talk btw?

[18:14] <costyn> quick question: if a power reg no longer provides the specified voltage, giving either too high or too low, I've probably fried it during soldering right?
[18:14] <Randomskk> yes. assuming it's fixed output not variable
[18:14] PaulCDR (5ad45091@gateway/web/freenode/ip. joined #highaltitude.
[18:14] <Randomskk> also assuming it's not being shorted
[18:14] <costyn> Randomskk: fixed yes
[18:14] <Randomskk> or the supply is the wrong voltage
[18:14] <costyn> Randomskk: haven't checkd it... supply voltage is ok
[18:15] <Randomskk> if it's a 1A regulator and you're trying to draw like 3A, the voltage will drop and stuff
[18:15] <costyn> hadn't checked for shorting, but a 3940 that was supposed to give 3.3v now gives 4.8
[18:15] <Randomskk> if the input voltage is too low it'l not work
[18:15] <Randomskk> huh
[18:15] <Randomskk> it might also be because you didn't give it sufficient output capacitance
[18:15] <Randomskk> did you put capacitors on the output pin, with values suggested by the datasheet?
[18:15] <costyn> Randomskk: ah... good to konw, I acutally didn't give it any output caps
[18:15] <Randomskk> aha
[18:15] <Randomskk> fix that
[18:16] <Randomskk> linear regulators always need output capacitors
[18:16] <costyn> ok :)
[18:16] <Randomskk> otherwise they can go unstable
[18:16] <Randomskk> which may be what's happenign here
[18:16] <Randomskk> do you have an oscilloscope?
[18:16] <costyn> I thought that was necesssary only if your input is unstable
[18:16] <Randomskk> (sometimes you can get away without caps when breadboarding because breadboard pins have so much capacitance anyway)
[18:16] <Randomskk> no
[18:16] <Randomskk> the regulator is an active component with feedback loops n stuff
[18:16] <costyn> well thanks for the advice... gonna fix that

[18:38] <mrShrimp> Does someone have time to help me troubleshoot my flight computer?
[18:38] <mrShrimp> Everything except the NTX2 seems to be functioning properly
[18:38] <Hix> is it doing anything?
[18:39] <mrShrimp> It transmits what looks like a carrier wave with a bunch of lesser interference waves spaced out from it.
[18:39] <mrShrimp> and the carrier is tilted to the left, so it is moving to lower and lower frequencies.
[18:40] <Hix> voltage stable?
[18:40] <mrShrimp> I'm running it off of 5.1 volts or so from a variable voltage regulator
[18:41] <Hix> with cpsa on it?
[18:41] <Hix> caps
[18:41] <Hix> sorry bad typing as per usual
[18:42] <mrShrimp> It was working fine on the breadboard, maybe there is something wrong with how I wired it...
[18:42] mclane (~uli@p4FCF5FFC.dip.t-dialin.net) joined #highaltitude.
[18:42] <mrShrimp> What do you mean by caps?
[18:42] <Hix> i had problems with resistor values, worth checking
[18:43] <mrShrimp> I'll do that.
[18:43] <Hix> from what I've learned, voltage regs need capacitors to stabilise the voltage, shoould have values on the spec sheet
[18:43] <Hix> otherwise they fluctuate
[18:43] <mrShrimp> right
[18:43] <mrShrimp> but it was working fine without them on the breadboard
[18:43] <Hix> though others on here will be able to fill you in in greater detail.
[18:44] <mrShrimp> hm
[18:44] <Hix> you followed the guide on the wiki?
[18:44] <mrShrimp> Mostly, yes
[18:45] <mrShrimp> For the ntx2 part, I used that code.
[18:45] <Hix> worth double checking the connections, voltage and resistors
[18:45] <Hix> you should be able to checkk the voltage from the divider to see that it's correct with a DMM
[18:46] <Hix> mmmm food bbl
[18:46] <mrShrimp> ok, thanks for your help!
[18:52] <mrShrimp> Is it possible that the NTX2 was damaged by the heat of the soldering iron?
[18:54] <Hix> wouldn't have thought so, i soldered some header pins onto mine as the originals were a bit fragiel, i spent a lot of time trying to get the old ones off and it's all fine.

[19:15] <Hix> and you then use the basics from the NTX2 test sketch but you change the string to be the values you wish from the gps parsing
[19:15] <Hix> sprintf is the thing you need to work out.

[19:19] <Babs> No, not SLS, printed on an Objet printer
[19:20] <PaulCDR> what about insulation?
[19:20] <Babs> A pain to clean the support material off but works ok i guess
[19:21] <Babs> Thats just the support cage, the whole thing is encased in 5 polystyrene panels. One for each of the three sides, one top and one bottom. In one sense its no different from the conventional all polystyrene construction, its just a bit stronger and allows me to mount a stabilising gimbal above it to try and stop the camera picthing around

[19:24] <Babs> The whole rig will be a little heavy and that will limit altitude, but for this one I'm trying to up the photo quality up there
[19:25] <Hix> sure - dslr much better quality. might want to consider a cutdown just in case. EOS in the drink would hurt
[19:26] <mrShrimp> The voltage that the

[19:26] <mrShrimp> I don't see how that would affect the signal in a noticable way.

[19:35] <Upu> going to be very interested to see how that works
[19:35] <Babs> upu, are you running the cutdown from an arduino?
[19:35] <Hix> I've been looking into gimbal design
[19:35] <Upu> I could do, I never actually did it
[19:35] <Upu> one of my previous boards had a fet in the to allow a cutdown trigger
[19:36] <Upu> I'm using Geofencing to ascertain which country I'm in to adjust my APRS callsign accordingly
[19:36] <Hix> liked your pyro test vids upu
[19:36] <Upu> but its the same deal for what you want, once you go out of a set boundary bang
[19:36] <Upu> Yeah I did a few pyro cut doesn
[19:36] <Upu> downs
[19:36] <Hix> is it using a big array?
[19:37] <Upu> legallly they are dubious
[19:37] <mrShrimp> How do you implement geofencing in a microcontroller?
[19:37] <Upu> I'll tell you exactly :
[19:37] <Upu> 1/ http://www.birdtheme.org/useful/googletool.html make KML
[19:37] <bertrik> mrShrimp: there's a really nice algorithm that is surprisingly simple if you see it as code
[19:37] <Upu> 2/ Convert KML to array i.e :

[19:41] <Hix> and cheers fsphil for the idea
[19:41] <mrShrimp> I might consider testing it on a smaller scale with my launch, since it does not seem to need any more hardware than a GPS.
[19:41] <mattbrejza> i would hve been lazy and checked for a box, but that does seem somewhat better

[19:42] <mrShrimp> There are so many private properties in Washington State that this could be useful in letting me know in what sort of area the payload lands in.
[19:42] <Upu> I'm working through Europe
[19:43] <Babs> Upu do you use tinygps to parse the data through to the cutdown code too?
[19:43] <Upu> no I wrote my own parser but you could use it
[19:43] <Upu> that code I've posted assumes the data coming in is UBX
[19:43] <Upu> i.e 549271420,86132810 = 54.9271420,8.6132810
[19:44] <Upu> I don't think TinyGPS supports that though I could be wrong
[19:44] <mrShrimp> It's more compact than TinyGPS I would imagine?
[19:44] <Upu> I've never checked
[19:44] <Hix> tinygps seems a bit ironic
[19:45] <mrShrimp> true
[19:45] <Hix> my basic sketch is 12kb
[19:45] <mattbrejza> tinygps converts strings to float? then you have to convert them back?
[19:45] <mrShrimp> I thought you could request data as floating point.
[19:45] <Babs> That would be awesome - I haven't coded since BASIC when I was 6 #abitoutofpractice. I understand the various bits of coding, but putting it all together in a package is beyond me
[19:46] <Upu> speak to oz1sky/Brian when he's online Babs

[19:53] <Upu> interesting
[19:54] <Hix> i was thinkiing of using various diameters of pvc piping, cheaper and easier. with mini bearings in to reduce inertia
[19:55] <Hix> friction rather
[19:55] <mattbrejza> eroomde produced an actively stablised platform but it was too heavy to fly i seem to remember
[19:56] <Hix> i suppose it could be dome with an IMU and some ballraced quick servos
[19:56] <Hix> but costly
[19:56] <EspacioCercano> Anyone else having issues with the CUSF landing predictor? I'm getting server errors
[19:56] <Babs> The PVC piping route is well established and there are a few videos up of people who have stablised gopros that way
[19:57] <Lunar_Lander> Upu, how did you notice the city?

[20:19] <mrShrimp> You could make a function for a smoothed perimeter of country boundaries, then distance each point a certain space apart from each other. That might not work in all circumstances though.
[20:19] <mrShrimp> That might be overcomplicating things though.
[20:20] <mrShrimp> Why do I say "though" so much! -_-
[20:21] <Upu> limited processing power on the microcontrollers
[20:22] <mrShrimp> that would be just to determine the number of points needed to form accurate polygons
[20:23] <Babs> paulcdr yes, there is a bearing in the horizontal plane that it can spin independently around
[20:24] <Babs> only issue is that the cutdown mechanism then can't connect (as it would twist independently of the cage)
[20:25] <Babs> so i've got an arduino nano which I'm going to sit in a small polystyrene cube above the parachute. downside: more weight
[20:30] <PaulCDR> and these are your designs babs, well done
[20:30] <Upu> THis is what I'm basing my geofences on (its a map for all the Romanians who can come to the UK now due to the relaxing of the border controls) http://s2.b3ta.com/host/creative/77938/1359890111/updated.jpg
[20:33] <Babs> Yes, all my CAD designs, although I've used various other projects for inspiration clearly (particularly the gopro gimbal). I taught myself CAD on sketchup. Its pretty good and free. The only downside is then you want to 3d print everything as any other way seems too much of a compromise, but it isn't cheap.
[20:34] <PaulCDR> how much did it cost for the 3d printing?

[21:19] <cuddykid> crashes the "messages" application too if someone sends a message containing "File.." - gets in a crash loop as every time it starts up it sees the dreaded string and crashes
[21:19] <mattbrejza> assuming that works you just need to hack into itunes.apple.com and add your code there

[21:35] <nigelvh> If this doesn't do it, I don't know what will. It uses some javascript to place it in the URL bar, and then should have itunes try and open a url with the string in it.

[22:26] <mrShrimp> Hey, can anyone help me identify why this is happening? http://imgur.com/8BS03EU
[22:27] <KT5TK> Wgat have you been drinking before?
[22:27] <mrShrimp> ?
[22:27] <KT5TK> What
[22:28] <mrShrimp> I am using an NTX2 to transmit.
[22:28] <Randomskk> mrShrimp: probably temperature change causing the frequency to drift
[22:28] <KT5TK> Honestly this looks like a power supply
[22:28] <mrShrimp> I switched the voltage regulator
[22:28] <mrShrimp> and added caps, so now the voltage is stable enough.
[22:28] <mrShrimp> That is supposed to be a RTTY signal
[22:28] <mrShrimp> *an
[22:28] <KT5TK> If it's your NTX, then it's definitely not stable enough
[22:29] <nigelvh> Looks like you're only generating one tone, but you're also drifting.
[22:29] <mrShrimp> I used a variable voltage regulator without capacitors in the breadboard version of the circuit
[22:29] <mrShrimp> and that worked well.
[22:29] Dan-K2VOL (Dan-K2VOL@ left #highaltitude.
[22:30] <mrShrimp> When I soldered the components on veroboard I started getting this from the NTX2
[22:30] <KT5TK> Are you sure that you connected the ground properly?
[22:30] <mrShrimp> with a 4.7k resistor I believe
[22:30] <mrShrimp> I will check.
[22:31] <KT5TK> Take a photo of what you built and send a circuid diagram
[22:31] <KT5TK> circuit
[22:31] <mrShrimp> Are there any good programs form the circuit diagram?
[22:32] <KT5TK> First I need to see the diagram, then I may tell
[22:32] <mrShrimp> You mean a schematic, or just a diagram?
[22:32] <KT5TK> schematic
[22:33] <KT5TK> What regulator are you using?
[22:33] <mrShrimp> 7805
[22:34] <mrShrimp> The rest of the circuit functions properly.
[22:34] <KT5TK> more precisely?

[22:36] <mrShrimp> I am logging GPS data to an SD card via ATMega328
[22:37] <mrShrimp> ATmega*
[22:37] <KT5TK> doesn't mean that the supply is stable.
[22:37] <KT5TK> The freq drift of the transmitter is more sensible
[22:38] <mrShrimp> The NTX2 has it's own regulator and works as long as its power rail does not fluctuate more than "ripple/noise content >100mVpk-pk"
[22:39] <KT5TK> Is that line definitely generated by the transmitter?
[22:39] <nigelvh> That doesn't mean that the supply is putting out enough power to run everything, which can cause all sorts of isues.

[22:39] <chrisstubbs> oh
[22:40] <nigelvh> What 7805 are you using?

[22:42] <mrShrimp> No, that's strange
[22:42] <gonzo_> missed the chat, do you have a screen cap of the rx?
[22:43] <mrShrimp> http://imgur.com/8BS03EU
[22:43] <mrShrimp> nigelvh : the voltage regulator looks like this http://2.bp.blogspot.com/_seix_ku9EhI/TT2j182dSaI/AAAAAAAAAS4/58K4KxPY-ws/s1600/7805-pin-gnd-voltage-regulator-5volts-converter.jpg
[22:44] <mrShrimp> but it says CT on it, which should look like the picture you linked to.
[22:44] <nigelvh> Ok, if it's a TO-220 version of a 7805 that should be able to supply plenty of power.
[22:45] <mrShrimp> Upu: I am attempting to transmit
[22:45] <gonzo_> you have the decoupling caps as advised in the datasheet for the 7805 and have them close to the reg?
[22:45] <mrShrimp> but it doesn't seem to be working.
[22:45] <Upu> do you only have one line on the water fall ?
[22:45] <gonzo_> as the 78xx series of regs can break into oscillation of the decoupling caps are not there
[22:45] <mrShrimp> gonzo_: I just used two disc caps I found lying around.
[22:45] <mrShrimp> Upu: yes
[22:46] <Upu> well you're not transmitting
[22:46] <Upu> have you go the hi / lo test working ?
[22:46] <mrShrimp> I got the entire circuit working in breadboard form

[22:47] <Upu> ok well go back to making the radio do a high and a low tone
[22:47] <Hix> is there a bridge somewhere? continuity test will show it on DMM
[22:47] <Upu> check the resitor values
[22:47] <Upu> check the pin driving it is going high and low
[22:47] <Hix> ^ was one of my problems
[22:48] <Hix> duff resistor
[22:48] <Hix> changed - solved
[22:48] <mrShrimp> The resistor values are correct and the resistors work. I know because I used them in the successful test on the breadboard.
[22:49] <Upu> is the pin going high and low properly
[22:49] <Hix> were the caps the right value as indicated on spec sheet
[22:49] <Upu> just use the example blink code with long delays
[22:49] <nigelvh> And check for solder shorts
[22:49] <mrShrimp> Ok, this will take 10 minutes probably.
[22:49] <Upu> I don't want to state the obvious but if it was working before and it isn't now something is wrong :)

[23:05] <mrShrimp> The NTX2 casing is not on the conductive side of the Veroboard though. How would that happen?
[23:05] <Hix> solder seeped through somewhere maybe?

[23:06] <mrShrimp> Here is what I used to plan the circuit
[23:07] <hye> does anyone know the which regulator is on the ntx2?
[23:08] <mrShrimp> There is nothing that could have seeped through onto the casing
[23:09] <Hix> can you desolder it and put it on a breadboard to test?

[23:10] <mrShrimp> That would be so much work!
[23:10] <mrShrimp> I already got it to work on a breadboard.
[23:11] <nigelvh> Well something has to have changed.
[23:14] <Maxell> And if it's a bad solder you'd have to resolder is somehow
[23:14] <Hix> worth a shot
[23:15] <Hix> have you got an arduino or just the chip
[23:15] <mrShrimp> just the chip
[23:15] <Hix> bugger
[23:15] <Hix> only one of em?
[23:15] <mrShrimp> I have another one.
[23:16] <mrShrimp> I didn't solder the chip straight in. I used an IC socket.
[23:16] <Hix> maybe set the breadboard up and just swap NTX2 over?
[23:17] <mrShrimp> What would I test for?
[23:17] <Hix> you said you thought you fried the NTX2 earlier
[23:18] <mrShrimp> I just did a high/low test with it, and it worked.
[23:18] <Hix> ah ok, missed that
[23:18] <Adam012> If you're using stripboard rescore the lines with a little craft knife.
[23:18] <mrShrimp> I'll do that. Flux isn't conductive at all, is it?
[23:18] <nigelvh> If the high/low test worked, then it would seem that the hardware works, so what has changed in your software?
