[01:19] <SpeedEvil> This is actually a more-or-less comparable price to 'normal' stainless steel hot water cylinders.
[01:19] <SpeedEvil> It's a little cheaper.
[01:20] <NigeyS> thats crazy stuff!
[01:21] <SpeedEvil> It's fortunately in the range I can't quite justify as an impulse purchase.
[01:21] <NigeyS> lol your bank balance thanks you !
[01:22] <SpeedEvil> It would actually pay back in a 'reasonable' time.
[01:23] <SpeedEvil> ~10 years, compared to a very well insulated conventional tank.

[09:04] <Darkside> hey fsphil-laptop
[09:04] <Darkside> going through your hadie code atm..
[09:04] <Darkside> trying to work out how i can get this workign with the arduino ide, and working on my board :P
[09:10] <fsphil-laptop> oooh
[09:10] <fsphil-laptop> how's it so far?
[09:29] <Darkside> pff
[09:29] <Darkside> havent gotten far
[09:29] <Darkside> just working out what i'm going to need to replace
[09:29] <Darkside> thankfully the way you've structured the code makes it not so hard
[09:30] <Darkside> also i notice you're using single pin RTTY stuff
[09:30] <fsphil-laptop> aye
[09:31] <Darkside> if i remove the gps stuff, i could probably drop this directly onto one of the boards i have here
[09:32] <Darkside> actually not quite
[09:32] <fsphil-laptop> there's probably some stuff in the init() bits specific to the 644p
[09:33] <Darkside> yup
[09:33] <Darkside> also i'd be handling the timers differently
[09:34] <Darkside> gotta remember how i was doing the 600 baud stuff
[09:35] <Darkside> aha, found it
[09:35] <Darkside> Timer1.initialize(1666); // 600 Baud
[09:35] <fsphil-laptop> lol
[09:35] <Darkside> and Timer1.attachInterrupt(rtty_tx_interrupt);
[09:35] <Darkside> :P
[09:36] <Darkside> but yeah - timer1, not timer0
[09:36] <Darkside> since arduino uses timer0 for its internal stuff
[09:36] <fsphil-laptop> ah
[09:36] <Darkside> anyway, i think i can start playing with this
[09:36] <Darkside> i think i'll get your rtty library compiling within the arduino framework first
[09:36] <Darkside> then move on from there
[09:36] <Darkside> since your rtty framework is nice
[09:37] <number10> not being familiar with this arduino - do you use a debugger with it
[09:37] <Darkside> ack
[09:37] <Darkside> while(txlen > 0) while(txlen > 0);
[09:37] <Darkside> what the hell
[09:37] <Darkside> fsphil-laptop: ^
[09:37] <fsphil-laptop> er, yea
[09:38] <Darkside> >_>
[09:38] <Darkside> timing hax?
[09:38] <fsphil-laptop> interrupt hax -- txlen is changed from an interrupt
[09:38] <Darkside> oh yeah
[09:38] <Darkside> so you check it twice
[09:39] <Darkside> concurrency issues
[09:39] <fsphil-laptop> that's a hacky way to make sure it's not been changed in the middle of it being compared
[09:39] <Darkside> makes sense
[09:39] <fsphil-laptop> forgot about that actually
[09:39] <fsphil-laptop> I should probably add a better comment there
[09:40] <DanielRichman> if you have a look at avr libc (I assume it's AVR?) then they provide a way to atomically test something with interrupts disabled, then sleep with interrupts enabled for changes, repeat
[09:41] <DanielRichman> * look at the avr libc sleep.h docs
[09:41] <fsphil-laptop> I didn't want to disable or block the interrupt while it's doing the rtty
[09:41] <Darkside> fsphil-laptop: what shift were you doing the 600 baud rtty at?
[09:42] <Darkside> my boards are locked to 425Hz shift atm..
[09:42] <DanielRichman> you just disable the interrupt to test your global variable
[09:42] <fsphil-laptop> I used 350hz for 300 baud .. double that for 600. Tim is using 600 Hz for 600 bau
[09:42] <Darkside> i might be able to futz with the deviation and fix it up
[09:42] <fsphil-laptop> baud
[09:42] <Darkside> ok
[09:42] <DanielRichman> then enable them again to either act what you tested or go back to sleep
[09:42] <fsphil-laptop> I think anything >=600 hz is fine
[09:42] <Darkside> ok will see if i can make this higher
[09:44] <fsphil-laptop> it would probably work at 425 too but with a bit less range
[09:48] <Darkside> i just tuned my module up to 600 hz
[09:48] <Darkside> just matter of fiddling with the knobs
[09:49] <fsphil-laptop> all good radios have 'em
[09:50] <fsphil-laptop> nigel and I tuned one that way, ended up at 434.670 or something silly like that, but a perfect shift
[09:50] <Darkside> yeah this is slightly off frequency
[09:50] <Darkside> but thats ok

[11:41] <Darkside> i see all teh S_stuff declared as an enum within the ssdv struct
[11:41] <fsphil-laptop> aah C++ difference likely
[11:41] <fsphil-laptop> namespace stuffs
[11:41] <Darkside> prolly
[11:41] <fsphil-laptop> I don't refer to the enums by name
[11:41] <Darkside> so how do i fix this..
[11:42] <fsphil-laptop> looking now
[11:45] <Darkside> bring the enum outside the struct?
[11:45] <fsphil-laptop> worth a try -- the docs suggest enums are more or less the same in C and C++
[11:46] <Darkside> moving the enum outside of the struct removed a lot of errors
[11:46] <Darkside> now i need to define the enum within teh struct
[11:48] <fsphil-laptop> try s.S_HUFF .. etc
[11:48] <fsphil-laptop> oh you've moved it
[11:48] <fsphil-laptop> you'll have to name the enum
[11:48] <Darkside> ill put it back in
[11:48] <Darkside> eh?
[11:48] <Darkside> ok... how
[11:48] <Darkside> this is C stuff i've never used before..
[11:48] <fsphil-laptop> enum enumsname { values };
[11:49] <Darkside> err
[11:49] <Darkside> ffff
[11:49] <fsphil-laptop> enum states_t maybe
[11:49] <Darkside> nah, what i mean is if i have the enum outside the struct
[11:49] <fsphil-laptop> then you can just declare a: state_t state;
[11:49] <fsphil-laptop> in the struct
[11:49] <Darkside> hrmm

[12:11] <fsphil-laptop> try 9600
[12:11] <Darkside> it only auto detects >14400
[12:11] <Darkside> or so the datasheet says

[12:27] <fsphil-laptop> lol
[12:28] <Darkside> pony!
[12:29] <fsphil-laptop> naturally :)
[12:29] <fsphil-laptop> 600 baud is nice
[12:30] <Darkside> yeah
[12:30] <Darkside> we're gonna get a lot of images
[12:30] <Darkside> whats going to happen if the image counter overflows
[12:30] <Darkside> will it handle it?
[12:30] <fsphil-laptop> yea.. it will consider an image done after 5 minutes of no new data
[12:31] <Darkside> ok
[12:31] <fsphil-laptop> so only a problem if you transmit more than 255 images in 5 minutes
[12:31] <fsphil-laptop> which I'd love to be a problem
[12:34] <Darkside> about 3 minutes per image
[12:34] <Darkside> well i'm surprised at how easy this was to get working
[12:34] <fsphil-laptop> me too lol
[12:35] <Darkside> ill have to dump the arduino sketch somewhere so you can see
[12:35] <fsphil-laptop> I'll make the struct/enum change here too
[12:36] <Darkside> hmm 120 degree lens
[12:37] <fsphil-laptop> wider than I thought it was
[12:37] <fsphil-laptop> btw the last packet is missing from each image
[12:38] <Darkside> hmm
[12:38] <Darkside> i wonder why
[12:39] <fsphil-laptop> not sure, it should always transmit a packet unless the encoder or camera returned an error
[12:40] <fsphil-laptop> or possibly you're writing over the image packet as it's sending
[12:43] <fsphil-laptop> if you're sending packets continuously with no break you might need a double buffer
[12:44] <Darkside> ahh ok
[12:44] <fsphil-laptop> I suppose you could verify that by sending a bit of text between packets
[12:44] <fsphil-laptop> or calling rtx_wait()
[12:45] <Darkside> ill have it wait
[12:45] parishde (~yaaic@178.108.65.72) joined #highaltitude.
[12:47] <Darkside> well i think we'll fly this as a dedicated imagery payload
[12:47] <Darkside> its going into a 100mW 2m transmitter

[12:49] <fsphil-laptop> ah there we go
[12:49] <Darkside> i think it got the last packet then
[12:49] <Darkside> it sends a callsign ebtween every packet
[12:49] <fsphil-laptop> that would be perfect
[12:50] <fsphil-laptop> you doing something to cause that dropped packet?
[12:50] <Darkside> i think VK5ZM did
[12:51] <fsphil-laptop> ah, that's not you receiving
[12:51] <Darkside> yeah its a guy 7km away :P
[12:51] <fsphil-laptop> you people with your 100mw ;)
[12:51] <Darkside> so did you have the lens covered? :P
[12:51] <Darkside> i mean
[12:51] <Darkside> plastic cover or something to seal the payload
[12:51] <Darkside> or was it open to the elements
[12:52] <fsphil-laptop> it was naked
[12:52] <Darkside> ok
[12:52] <fsphil-laptop> yea that image was complete from the looks of it
[12:52] <Darkside> cool
[12:52] <fsphil-laptop> I only noticed a problem > 30km when the ground was becoming over exposed
[12:52] <Darkside> OH CRAP
[12:53] <Darkside> I'M ON THE INTERNETS

[12:54] <fsphil-laptop> what's the light level like in the room?
[12:54] <Darkside> not too bright
[12:55] <fsphil-laptop> that's not bad. there's always a bit of graininess even in bright light
[12:56] <fsphil-laptop> that's a big image

[13:09] <fsphil-laptop> images at night would be pretty dull :)
[13:09] <Darkside> yeah
[13:09] <Darkside> at least they'd send fast
[13:10] <Darkside> oh yeah
[13:10] <Darkside> did you ever get it writing images to a sd card?
[13:10] <Darkside> because i do have that option on this board
[13:10] <fsphil-laptop> Not yet, I couldn't squeeze in an sd card on the last one
[13:10] <Darkside> i'm using one of my old mininut boards for this
[13:11] <fsphil-laptop> I thought about writing the packets directly to a card, without a file system
[13:12] <Darkside> then parsing it out of a disk image
[13:13] <fsphil-laptop> it's easy to spot a packet so reading it from the raw image would be trivial

[14:57] <costyn> ghello
[14:59] <costyn> I finally went up on my roof and got down the old discone that was left there by some previous tennant. The label says it's an Icom AH-7000, when I disassembled it, underneath the exterior is still looks pristine
[15:02] <fsphil-laptop> icom usually make good stuffs
[15:03] <fsphil-laptop> ooh, it can be used to transmit from on certain frequencies too
[15:04] <costyn> yea pretty interesting, although I won't be doing any sending until I get my license
[15:04] <Darkside> well a discone is meant to be a good match at anything in its rated rx rante
[15:04] <Darkside> range*
[15:04] <Darkside> no gain tho
[15:04] <fsphil-laptop> it's seems to be getting generally good reviews that model
[15:05] <fsphil-laptop> you need some good rg213 cable and n plugs now costyn :)
[15:05] <costyn> fsphil-laptop: thanks, just the kind of info I need... the 817 has a BNC connector though right?
[15:06] <fsphil-laptop> bnc and the old so-259-or-something
[15:06] <fsphil-laptop> I'd stick N on both ends of the cable, then get an adaptor
[15:06] <costyn> ok
[15:07] <costyn> can I connect those N connectors myself to the coax? is that hard/tricky to get right?
[15:07] <fsphil-laptop> it's not too bad
[15:07] <fsphil-laptop> but I'd practice on something first if you've not done it before
[15:08] <fsphil-laptop> needs a crimper of the proper size, and ideally a soldering iron
[15:09] <costyn> ok
[15:09] <costyn> the crimper is a special tool? or can I use a generic stripper/crimper tool?
[15:10] <Darkside> depends on the connector
[15:10] <Darkside> some n connectors can be soldered, others have to be crimped
[15:10] <Darkside> i prefer the solder ones as i don't have a proper crimping tool
[15:10] <Darkside> and yeah, you want a proper crimping tool if you're going to use the crimp connectors
[15:10] <fsphil-laptop> yea
[15:11] <fsphil-laptop> I crimp mine, but always put a bit of solder on the centre pin anyway
[15:11] <costyn> ok
[15:12] <fsphil-laptop> then wrap the plug and socket in self amalgamating tape to keep the weather out
[15:12] <costyn> the previous user liberally applied silicone kit in various places. seems to have worked nicely
[15:12] <fsphil-laptop> that too
[15:13] <fsphil-laptop> wonder why they didn't take it with them
[15:13] <fsphil-laptop> might be worth testing it before buying any long lengths of cable
[15:14] <costyn> ok... how would I go about testing it... attach it to a radio (i have a 2m handheld) and see if it recieves anything?
[15:14] <NigelMoby> Soldering n connectors is oh so much fun.
[15:15] <Laurenceb_> anyone here very familiar with gdb?

[20:14] <fsphil-laptop> eos5 -- it was never mentioned in here
[20:14] <fsphil-laptop> guy in ireland who launches occasionally .. doesn't seem to use prediction though
[20:15] <natrium42> ah, and it landed in the north sea?
[20:15] <fsphil-laptop> this one has a spot satellite thingy
[20:15] <fsphil-laptop> the atlantic, between here and scotland
[20:15] <fsphil-laptop> http://share.findmespot.com/shared/faces/viewspots.jsp?glId=02r6VJRvLosafHWrmL6CQZfx6cuphtl94
[20:16] <fsphil-laptop> I'm fairly certain that one is lost
[20:16] <fsphil-laptop> unless the spot can last until it washes up
[20:20] <fsphil-laptop> or the guy owns a boat :)
[20:27] <Lunar_Lander> xD
[20:27] <Lunar_Lander> or he can fly
[20:27] <Lunar_Lander> maybe he is R Kelly?
[20:27] <Lunar_Lander> XD
[20:27] <Lunar_Lander> btw fsphil-laptop isn't "The Kelly Family" from Ireland?
[20:28] <fsphil-laptop> not sure who that is?
[20:28] <Lunar_Lander> ah that was a family who made music in the 90's
[20:28] <fsphil-laptop> ah
[20:29] <fsphil-laptop> not sure
[20:29] <Lunar_Lander> ah no
[20:29] <Lunar_Lander> they are from the US
[20:29] <Lunar_Lander> still xD
[20:29] <Lunar_Lander> here
[20:29] <Lunar_Lander> http://www.youtube.com/watch?v=t7xSj9ixnOg
[20:29] <Lunar_Lander> he makes fun of the chemistry show there
[20:29] <Lunar_Lander> xD
[20:29] <Lunar_Lander> the professor says "This here could be iron. Let us test it with the magnet"
[20:29] <Lunar_Lander> xD just watch it
[20:50] <nosebleedKT> airplanes dont have APRS transmitters?
[20:50] <nosebleedKT> on 144.8mhz ?
[20:51] <Lunar_Lander> not that I know of
[20:53] <fsphil-laptop> they have their own systems
[20:53] <fsphil-laptop> but that's not to say some pilot somewhere doesn't
[20:54] <nosebleedKT> Lunar_Lander: These days I will order a new pcbs for aprs trackers from seeedstudio. Do you want to wait until i get them, so I send you all stuff at once? It whould take 2-3 weeks.
[20:55] <Lunar_Lander> sounds good
[20:55] <Lunar_Lander> send them together when you got them
[20:55] <Lunar_Lander> :)
[20:55] <nosebleedKT> yes thats what im thinking
[20:56] <nosebleedKT> you need NRX1 or RX1 for receiving aprs
[20:56] <nosebleedKT> those are the radios which are compatible with my radioshield
[20:57] <Lunar_Lander> yea
[20:57] <nosebleedKT> new radioshield got an opamp to amplify the audio signal and a potentiometer to adjust manually the amplification level
[20:57] <Lunar_Lander> cool!
[20:58] <Lunar_Lander> and I got the resistors and capacitors for the gamma-photon detector
[20:58] <nosebleedKT> lol
[20:58] <Lunar_Lander> and I did a sample order from maxim for the opamps
[20:58] <Lunar_Lander> btw
[20:58] <Lunar_Lander> I got a 150kOhm resistor
[20:58] <Lunar_Lander> it is huge!
[20:58] <nosebleedKT> i need results from the detector. Might use it if you manage to make it.
[20:58] <Lunar_Lander> and the 1 Megaohm and 10 megaohm are small
[20:58] <Lunar_Lander> yeah
[20:59] <nosebleedKT> did u do anything with the batteries?
[20:59] <Lunar_Lander> not yet
[20:59] <Lunar_Lander> but I told my prof about it
[20:59] <Lunar_Lander> it won't be a problem to use the -80 fridge
[20:59] <nosebleedKT> i think germany will fall down to -20C for sure this winter so you might have a natural way of testing them
[20:59] <Lunar_Lander> xD!
[21:02] <nosebleedKT> in 3hrs i decoded 640 aprs messages without an antenna attached to the tracker
[21:03] <Lunar_Lander> cool!
[21:03] <fsphil-laptop> that's 638 more than I did with a large antenna in 24 hours ;)
[21:04] <Lunar_Lander> xD!
[21:04] <nosebleedKT> :P
[21:04] <nosebleedKT> enjoy the aprs world: http://pastebin.com/RQ48KF1j
[21:05] <fsphil-laptop> hah -- I just realised, I copied a driver to a computer using a 16Gb USB flash drive. The computers own hard drive is 10Gb

[21:53] <fsphil-laptop> all spiffy here, you?
[21:54] <TimZaman> \fine..
[21:56] <Lunar_Lander> hello TimZaman
[21:56] <TimZaman> hi
[21:56] <TimZaman> hey phil
[21:56] <TimZaman> potentially a lot of visitors on your live images page
[21:56] <Lunar_Lander> fsphil-laptop: did you see the chemistry video that I posted here btw?
[21:56] <TimZaman> you think your site can cope?
[21:56] <fsphil-laptop> it should do TimZaman
[21:56] <TimZaman> Maybe put a maximum of visible images there?
[21:56] <fsphil-laptop> I'll be watching it
[21:57] <fsphil-laptop> I may do
[21:57] <TimZaman> Are you free then?
[21:57] <fsphil-laptop> yea I'm off that day
[21:57] <TimZaman> Keep a close eye on it
[21:57] <TimZaman> wow thanks that'd be great
[21:58] <fsphil-laptop> if the weather is good I might head out to try and receive it
[21:59] <TimZaman> fsphil-laptop: oops im talking to your other name in pm
[22:00] <fsphil-laptop> lol
[22:00] <fsphil-laptop> yea I better log that out
[22:00] <fsphil-laptop> two machines is confusing
[22:00] <TimZaman> fsphil-laptop: predictions are fairly nice, it will go to south east

[22:08] <jcoxon> nah
[22:08] <jcoxon> look at the flight time
[22:08] <fsphil-laptop> ooh that's not right
[22:08] <jcoxon> yeah thats been happening for a few settings for me
[22:09] <Lunar_Lander> hi Dan-K2VOL
[22:13] <jcoxon> fsphil-laptop, i just programmed that ACK code
[22:14] <jcoxon> the response from the gps doesn't match at all
[22:14] <fsphil-laptop> for the setting of the mode, or querying the mode?
[22:15] <jcoxon> well i'm now doing what juxta did?
[22:15] <jcoxon> so sending the command for airborne and parsing the response
[22:15] <fsphil-laptop> the ack for setting the mode
[22:15] <fsphil-laptop> yea
[22:15] <jcoxon> i added a serial.print of the return in HEX

[22:26] <fsphil-laptop> still alive :)
[22:26] <jcoxon> what happened?
[22:26] <fsphil-laptop> guy in donegal launched a balloon without doing a prediction apparently :)
[22:26] <jcoxon> oh dears!
[22:26] <jcoxon> haha
[22:27] <NigeyS> swim spot swim
[22:27] <jcoxon> fsphil-laptop, any idea why i get such an odd reply?

[22:30] <Lunar_Lander> yay Dan put up his superpressure talk on YT
[22:32] <fsphil-laptop> might be worth waiting for a B5 62
[22:33] <fsphil-laptop> then buffering up the next 6 bytes
[22:37] <jcoxon> ooooo
[22:37] <jcoxon> if i repeat the send
[22:37] <jcoxon> it works

[22:45] <jcoxon> okay
[22:45] <jcoxon> a serial.flush before sending hte command makes things a bit better
[22:45] <jcoxon> i get the correct response
[22:45] <jcoxon> if i repeat the command every say 10 secnds it works for the first 2 attempts and then stops
[22:45] <fsphil-laptop> ah, makes sense
[22:46] <fsphil-laptop> must be the nmea stuff filling it up
[22:46] <fsphil-laptop> odd
[22:47] <fsphil-laptop> even with flushing everything?
[22:47] <jcoxon> yeah

[23:05] <jcoxon> 1800ish
[23:05] <DanielRichman> oh cool, got ages then
[23:06] <Upu> jcoxon are all these questions getting in the way of you fixing the problem ? :)
