[07:40] <jcoxon> morning all
[07:40] <jcoxon> wow my backup beacon has now been going for nearly a week
[07:40] <jonsowman> morning jcoxon
[07:40] <jonsowman> nice :D
[07:40] <jonsowman> that's impressive
[07:40] <jonsowman> this is the cw/hell one?
[07:41] <jcoxon> yeah
[07:41] <jcoxon> had a set of lithiums that had been used a little bit so not good for a flight
[07:41] <jcoxon> its good to know how long it lasts for

[08:01] <jcoxon> jonsowman, i think its km/h
[08:02] <jonsowman> i assumed so
[08:02] <jonsowman> thank you :)

[08:10] m1x10 (~mixio@ppp089210100049.dsl.hol.gr) joined #highaltitude.
[08:11] <m1x10> morning mates :)
[08:11] <jonsowman> morning m1x10
[08:18] <m1x10> jonsowman: have you ever used arduino shields?
[08:18] <jonsowman> a couple
[08:18] <jonsowman> why?
[08:19] <m1x10> I have an issue
[08:19] <jonsowman> go on :) if I can't solve it I'm sure someone else can
[08:19] <m1x10> :):)
[08:19] <m1x10> the pinholes of the shields are quite big in comparison with the pin headers
[08:20] <m1x10> so when i stach on shield on arduino
[08:20] <m1x10> stack*
[08:20] <m1x10> so when i stack one shield on arduino
[08:20] <m1x10> some pins cant get the current
[08:21] <m1x10> in fact the pins get the current but they are not touching the shield pinholes so to pass the current to the shield
[08:21] <jcoxon> m1x10, have you added sockets or are you putting the header pins through the holes on the board itself?
[08:22] <m1x10> when you say sockets?
[08:22] <jcoxon> this is what you want
[08:22] <jcoxon> http://www.adafruit.com/index.php?main_page=product_info&cPath=17&products_id=85&zenid=336f9dc03a3ad9b03d41d6d4f0191eda
[08:22] <jcoxon> so you put them through the holes
[08:22] <jcoxon> and they give you a socket on the top
[08:22] <jcoxon> and pins on the bottom
[08:23] <m1x10> jcoxon, those are what the pin headers i have
[08:23] junderwood (~John@adsl.jcu.me.uk) joined #highaltitude.
[08:23] <m1x10> this is what i call pin headers
[08:23] <jonsowman> those should fit nicely into the arduino pin sockets
[08:23] <m1x10> yes the fit ok
[08:23] <m1x10> its not there the problem
[08:23] <jcoxon> and then you solder them into the holes
[08:23] <m1x10> yes, here is my issue
[08:24] <m1x10> i dont want to solder
[08:24] <jonsowman> why is that?
[08:24] <m1x10> cause i dont know !
[08:24] <jonsowman> you'll struggle to get decent continuity without it
[08:24] <jcoxon> they need to be soldered :-s
[08:24] <m1x10> I know its easy but ok...not now .
[08:24] <jonsowman> these would be good things to learn with. they will be pretty easy to solder :)
[08:25] <m1x10> can you show me a picture of a soldered socket?
[08:25] <m1x10> on an arduino shield?
[08:26] <jcoxon> http://farm4.static.flickr.com/3082/3137389446_550ca89aee.jpg
[08:26] <jonsowman> http://www.adafruit.com/adablog/wp-content/uploads/2009/07/diyshieldside-lrg.jpg
[08:26] <jonsowman> beaten to it :(
[08:26] <jcoxon> better b
[08:26] <jcoxon> better pic though
[08:26] <jonsowman> heh
[08:27] <m1x10> hmm, its soldered from below
[08:27] <jonsowman> indeed
[08:27] <jcoxon> so you'd heat the pin and apply a bit of solder
[08:27] <jcoxon> it'll naturally fill the hole
[08:27] <m1x10> i have soldering iron and the "hitter" (dunno its english word)
[08:27] <jcoxon> solder?
[08:28] <m1x10> ah
[08:28] <m1x10> lol
[08:28] <jcoxon> m1x10, best practice on something else first
[08:28] <jcoxon> solder some wires together for example
[08:28] <jonsowman> give it a try with some resistor legs and a bit of stripboard or suchlike
[08:28] <m1x10> so i have the soldering iron and the solder
[08:28] <jcoxon> just need a moist sponge to clean it with
[08:28] <jonsowman> you'll get the hang of it quick enough :)
[08:29] <m1x10> so i touch the solder to the pins they get hot and i touch the iron on the pin
[08:29] <jonsowman> other way round
[08:29] <jonsowman> use the iron to heat the joint for a few seconds
[08:29] <jonsowman> then touch a piece of solder onto the joint
[08:29] <jonsowman> it will melt and flow around
[08:29] <m1x10> joint?
[08:30] <jonsowman> the point where the two things you want to solder meet
[08:30] <m1x10> (sory english words gaps)
[08:30] <m1x10> so the joint is on the shield, right?
[08:30] <jonsowman> the part on the shield, and the pin itself
[08:30] <jcoxon> where the pin goes through the hole
[08:31] <jcoxon> the hole will be lined with metal
[08:31] <jonsowman> the idea is to bring both the pad and the pin to a temperature above solder's melting temperature
[08:31] <m1x10> ok i know that.
[08:31] <jonsowman> heating one of them alone will not work
[08:31] <jonsowman> :)
[08:31] <jonsowman> sorry - preaching to the converted
[08:32] <m1x10> so, i touch the solder to the pinhole
[08:32] <m1x10> then i touch the pinhole with the iron
[08:32] <m1x10> it gets melted and fill the hole
[08:32] <m1x10> right?
[08:33] <m1x10> im going to try !

[08:42] <jonsowman> you could say that

[08:42] <russss> it should be fixed now, my server was fucked
[08:42] <jonsowman> ah right, fair enough
[08:49] <m1x10> i soldered two pins
[08:49] <m1x10> !
[08:50] <jcoxon> \o/
[08:50] <jonsowman> good work
[08:53] <m1x10> 5 done!
[08:53] <jonsowman> excellent
[08:53] <jonsowman> not too hard really is it? :)
[08:54] <m1x10> but some iron touches the next iron
[08:54] <m1x10> no its easy enough
[08:54] <m1x10> :):)
[08:54] <jonsowman> melt it and use the tip of the iron to scrape away the solder that is touching two pins
[09:01] <jcoxon> anyone free to give this a quick skim over:
[09:01] <jcoxon> http://www.pegasushabproject.org.uk/wiki/doku.php/missions:ballasthalo:ballasthalo5
[09:02] <jcoxon> trying to have a single page for people to refer to
[09:02] <jcoxon> to save countless questions etc
[09:03] <juxta> hey jcoxon
[09:05] <jonsowman> right, off to germany
[09:05] <jonsowman> see you :)
[09:05] <jcoxon> jonsowman, have fun
[09:05] <jcoxon> juxta, was just about to ping you
[09:05] <jcoxon> :-)
[09:05] <Randomskk> have fun jonsowman
[09:06] <juxta> jcoxon - are you using the code the way you have it on your wiki? If so I think it will fail!
[09:06] <juxta> Serial.print(MSG[i], BYTE);
[09:06] <juxta> Serial.print(MSG[i], HEX);
[09:07] <jcoxon> got it from you!
[09:07] <juxta> the HEX output is for debug only - if you send it to the same place as the UBX binary, then the GPS won't know what to do with it
[09:07] <jcoxon> oh right
[09:07] <jcoxon> hehe
[09:07] <juxta> yeah - mine is a bit different, one goes to a soft serial, one goes to the hardware
[09:07] <juxta> (debug output)
[09:07] <jcoxon> oops
[09:07] <jcoxon> lucky you picked up on that
[09:07] <juxta> haha
[09:08] <jcoxon> of course would have realised evenutally when the super 'check mode' code is used
[09:08] <juxta> would have been caught by the ACK check though ;)
[09:08] <juxta> indeed, I should write that, hehe
[09:08] <jcoxon> i'll make a deal with you :-p
[09:08] <juxta> I built my payload box today, woo
[09:08] <jcoxon> if you magic up some code i'll build my online radio for you
[09:08] <juxta> haha
[09:08] <jcoxon> so you'll have a base in the UK
[09:08] <juxta> okay :D
[09:09] <jcoxon> even found a servo to turn the radio on and off with
[09:09] <juxta> ooh
[09:09] <juxta> how about reading the current freq? webcam?
[09:09] <jcoxon> yup
[09:09] <jcoxon> got that as well
[09:09] <jcoxon> all going to be running on an old powerbook
[09:10] <juxta> excellent!
[09:10] <juxta> I used that car windscreen thing to cover the payload, it turned out OK
[09:12] <juxta> jcoxon: is that a sparkfun box used structurally in your payload? :D
[09:12] <jcoxon> its just a tray to slide in and out of the polystyrene box
[09:13] <jcoxon> made it easy to put together on the desk
[09:14] <juxta> hehe
[09:14] <jcoxon> i like my sliding tray concept
[09:14] <juxta> yeah
[09:14] <jcoxon> makes it easy to get access to everything
[09:14] <juxta> I agree, that's a good idea
[09:15] <jcoxon> okay time to get working on this radio for you
[09:15] <juxta> i put a couple of compartments inside this payload, to seperate the battery pack and everything else
[09:15] <jcoxon> might call upon you to test some stuff
[09:15] <jcoxon> but won't be for a little while
[09:15] <juxta> sure - I'll be heading out in a little while, but will be back later on tonight
[09:15] <jcoxon> no worries
[09:15] <juxta> then I'll get working on that code & etch a board for my launch on Thursday
[09:16] <jcoxon> great

[09:18] <juxta> jonsowman: still about?
[09:22] <m1x10> finished the whole shield !
[09:22] <m1x10> time to test !
[09:26] <juxta> ping junderwood
[09:26] <junderwood> pong
[09:26] <juxta> hey there - was just going to ask you a quick question about the ublox/helical antenna if you had a sec
[09:27] <junderwood> go on
[09:27] <juxta> ideally I guess the antenna should point upwards - do you think the module will have a hard time keeping lock it it's pointed towards the horizon and it's spinning around a lot?
[09:28] <junderwood> I would certainly point it upward. If it points horizontally and has a ground plane underneath it (or anything radio-opaque) I think you'll have problems
[09:29] <juxta> hmm
[09:29] <junderwood> You would lose anything close to the horizon periodically.
[09:29] <junderwood> Even if the receiver managed to keep lock, it would struggle to get anything accurate.
[09:29] <juxta> drat, I didn't really take that into account when I built my enclosure!
[09:29] <junderwood> Tried exactly the same thing a few months ago
[09:30] <junderwood> Using a FSA03?
[09:30] <juxta> yep
[09:30] <junderwood> soldered directly onto the main pcb?
[09:30] <juxta> I guess I'll just fly my older computer which uses a lassen with a patch
[09:30] <juxta> yeah, soldered straight on
[09:30] <junderwood> Oh
[09:31] <junderwood> I used ribbon cable to connect the FSA to the computer - could then put it wherever I wanted
[09:31] <juxta> that's a good idea
[09:32] <juxta> I think I might be able to make it work though on second thoughts
[09:32] <juxta> will just need to be a bit creative and melt a bit of foam
[09:34] <juxta> hrm, just measured. annoyingly I dont think it'll fit as I'd like
[09:34] <junderwood> is it removable from the PCB?
[09:34] <junderwood> Solder braid, etc
[09:34] <junderwood> or hot air
[09:34] <juxta> yeah, I could do that
[09:41] <junderwood> makes life much easier

[09:44] <juxta> yeah, that is good :)
[09:47] <jcoxon> hmmm first roadblock
[09:47] <jcoxon> not enough usb ports
[09:48] <juxta> jcoxon: looks like I'll be flying my old computer on Thursday, the new one doesnt fit in the box I made
[09:48] <juxta> whoops
[09:49] <jcoxon> hehe
[09:50] <jcoxon> juxta, might have to skip the webcam bit
[09:50] <jcoxon> instead do dead reckoning
[09:50] <juxta> ah well
[09:50] <jcoxon> unless...
[09:50] <juxta> no USB hub on hand?
[09:51] <jcoxon> webcam + usb hub = badness
[09:51] <jcoxon> but will have a browse
[09:51] <jcoxon> could of course just use a jpeg camera
[09:51] <juxta> oh right, true
[09:51] <jcoxon> hehe
[09:51] <jcoxon> i'll have a look around
[09:51] <juxta> my FT90R came today
[09:51] <juxta> this thing is insanely small
[09:52] <jcoxon> ssb?
[09:52] <jcoxon> or just fm?
[09:52] <juxta> just FM
[09:52] <juxta> 2m/70cm
[09:56] <m1x10> ohhhhh
[09:56] <m1x10> Huston I got problem
[09:56] <m1x10> the shield and the gps get power just fine.
[09:56] <m1x10> but
[09:57] <m1x10> the other pins dont do anything
[10:01] <jcoxon> juxta, pah the webcam is too cool to not include
[10:01] <juxta> hurrah, feedback! :D
[10:08] <m1x10> GOD SAVE THE QUEEN !
[10:09] <m1x10> I got fully soldered shield working !
[10:12] <m1x10> THANKS GUYS !
[10:12] <m1x10> I will solder more now !! haha
[10:13] <fsphil> soldering is cool .. and by cool I mean really really hot
[10:16] <fsphil> jcoxon, do you have fake gps data for the scenarios you run
[10:19] <jcoxon> yeah
[10:20] <jcoxon> i use the gps emulator on the wiki to generate files containing nmea
[10:20] <jcoxon> initially based on kml files

[13:55] <fsphil> that's what I was wondering. I'd pictured some kind of complicated motor + rubber band trick to turn the knob, but the mic step is much more elegant
[13:55] <jcoxon> that was mkI :-p
[13:55] <jcoxon> did that a few years ago
[13:55] <fsphil> ah way ahead of me
[13:55] <jcoxon> it occasionally slipped though
[13:56] <jcoxon> next step is to find the usb hub so i can plug in my usb soundcard
[13:56] <jcoxon> and then i'll use nicecast to stream the audio
[13:56] <fsphil> there must be a microcontroller in there somewhere then -- I wonder if it could be talked to directly
[13:57] <jcoxon> not without some hassle, these machines are old...
[13:59] <fsphil> yea, I seen the one cusf lent to the cirrus guys - it looks like a 'proper' radio ;-)
[13:59] <jcoxon> they are amazing
[14:00] <fsphil> I check ebay now and then, they don't appear too often
[14:03] <fsphil> you should add an input box to set how many steps Up and Down send, to tune a bit faster
[14:03] <jcoxon> true
[14:08] <jcoxon> guess i should add on a login system as well

[14:55] <m1x10> if you put two GPS receivers in the same payload box, couldn't it get interference ?
[15:05] <fsphil> perhaps, if they're very very close together. best thing to do is try it
[15:06] <m1x10> fsphil: do you have any experience with two GPS in same place?
[15:07] <SpeedEvil> m1x10: You should not - generally
[15:08] <SpeedEvil> Simply for the reason that if they emitted any power at all into the GPS band, they would themselves have problems locking
[15:08] <SpeedEvil> I've tried several differnt (non-modular) recievers on top of each other with no issue
[15:08] <m1x10> SpeedEvil: my plan is two use two GPS systems, one for real time tracking and one for backup.
[15:09] <m1x10> I think someone has done that before

[15:36] <m1x10> ok
[16:02] <jcoxon> eek - went to buy a new 3.5mm jack cable and they were selling them for 15 pounds
[16:06] <SpeedEvil> Was it gold plated?
[16:06] <jcoxon> probably
[16:07] <jcoxon> it was also currys.digital
[16:07] <jcoxon> who aren't cheap
[16:09] <fsphil> even tesco are cheaper, and they're pretty bad for cables
[16:09] <jcoxon> oh they had run out
[16:10] <fsphil> ah typical
[16:10] <jcoxon> checked there first
[16:10] <fsphil> I'd suggest Argos but they're probably £20 there
[16:11] <cuddykid> jcoxon, hey there! Just going through the code you sent me last night, just a quick question, do you know what the pin "En" is?
[16:12] <jcoxon> yeah thats the engage pin on the radio
[16:12] <jcoxon> to turn it on and off
[16:12] <cuddykid> ahh, right, thanks :)
[16:12] <cuddykid> going to test it all out now!
[16:12] <jcoxon> if you turn the radio off you can save quite a bit of power
[16:13] <cuddykid> ok

[17:20] <cuddykid> e.g. what would the number of fields of the following be? $$HABE1,5,16:19:18,52.2789,-2.2415,69*31
[17:20] <jcoxon> yeah its counted

[17:53] <jnd> it's kinda dark
[17:53] <jcoxon> don't think my powerbook can cut it
[17:53] <jcoxon> yeh i haven't got the lighting right
[17:57] <jnd> now I hear something
[17:57] <jcoxon> just going to reset the stream
[17:58] <jnd> you lowered the bitrate, right?
[17:58] <jcoxon> yeah
[17:59] <jcoxon> basically my old powerbook is struggling
[18:00] <jcoxon> jnd, just put it up again
[18:00] <jcoxon> can you listen to the stream again - it might be not able to do two streams
[18:04] <jnd> maybe you could lower it but use better low-bitrate codec than mp3
[18:04] <jcoxon> its the webcam
[18:04] <jcoxon> thats whats messing everything up
[18:08] <DanielRichman> I can hear something but it's very quiet
[18:08] <jcoxon> how about now
[18:09] <DanielRichman> it's just the same
[18:09] <DanielRichman> I think
[18:09] <DanielRichman> sounds a bit... weird
[18:09] <jcoxon> oh its 2 transmitters over each other
[18:10] <DanielRichman> ohright
[18:14] <jcoxon> DanielRichman, now you can turn the volume up and down
[18:14] <DanielRichman> :o
[18:15] <DanielRichman> jcoxon: this is very cool
[18:15] <DanielRichman> it all works too :D
[18:15] <jcoxon> the webcam upsets me
[18:15] <DanielRichman> what's the setup?
[18:16] <DanielRichman> maybe you should have the up and down buttons move it by half the amount that they do currently
[18:16] <DanielRichman> and you need some more internetz
[18:16] <jcoxon> its either these steps or .1 of the steps
[18:16] <DanielRichman> oh the 790?
[18:16] <jcoxon> does it break up for you
[18:17] <DanielRichman> crackles occasionally, slightly
[18:18] <jcoxon> hmmm might have to switch it from my powerbook to my linux box
[18:18] <jcoxon> http://www.flickr.com/photos/jcoxon77/4764071975/
[18:20] <jcoxon> so a servo controls on/off and volume, optoisolators attached to the mic port and step freq up and down
[18:20] <jcoxon> and then a webcam faces the screen
[18:20] <DanielRichman> that's cool
[18:21] <jcoxon> lets try the linux box
[18:26] <m1x10> im going for coffee!! cu later guys.
[18:27] <fsphil> great setup
[18:27] <jcoxon> just needs to be a bit more brisk
[18:27] <jcoxon> also if i use linux then i can use much better camera software

[19:17] <Randomskk> what does testing involve
[19:17] <jcoxon> listening to an audio stream
[19:18] <Randomskk> sounds dangerous
[19:18] <Randomskk> by which I mean, URL?
[19:18] <jcoxon> http://pegasus4.no-ip.org:8000/example1.ogg.m3u
[19:18] <Randomskk> I hear some sort of noise
[19:18] <fsphil> aye
[19:19] <fsphil> standard radio stuffs
[19:19] <fsphil> oooh, rtty
[19:19] <Randomskk> now some sort of squeaking
[19:19] <jcoxon> fsphil, is is better then last time?
[19:19] <jcoxon> any breaks etc
[19:19] <fsphil> I didn't hear anything last time, jcoxon
[19:19] <Randomskk> your rtty is tuned too high, edmoore would say
[19:19] <Randomskk> his ears can detect where you are tuned to within the audio passband of fldigi
[19:20] <jcoxon> hehe
[19:20] <Randomskk> but it sounds decodable
[19:20] <jcoxon> Randomskk, http://www.flickr.com/photos/jcoxon77/4764071975/
[19:20] <jcoxon> so thats teh stream
[19:20] <jcoxon> and the control is here: http://pegasus4.no-ip.org/jcoxon.php
[19:20] <Randomskk> good stuff
[19:20] <Randomskk> what're you using it for?
[19:21] <jcoxon> its my remote station
[19:21] <jcoxon> had it working on my powerbook earlier but it wasn't fast enough
[19:21] <fsphil> hmm, my sound card can't record from mix
[19:21] <jcoxon> so have shifted to something more powerfull
[19:21] <fsphil> volume just dropped a bit
[19:21] <jcoxon> yeah i did that
[19:21] <fsphil> lemme fire up the other pc, see if I can decode the rtty
[19:22] <fsphil> be curious if it survives the vorbis compression
[19:22] <jcoxon> i just turned it off
[19:22] <jcoxon> it'll be back in a bit
[19:28] <jcoxon> okay should be back
[19:29] <jcoxon> on OSX you can use soundflower to pipe it back into dl-fldigi

[19:33] <jcoxon> at least 28days
[19:34] <fsphil> oooh, morse
[19:35] <jcoxon> and hellschreiber now
[19:35] <fsphil> it sounds like there's rtty mixed in with it
[19:35] <jcoxon> yeah i've got both my transmitters running
[19:36] <jcoxon> they'll seperate when the backup gets a bit colder
[19:36] <fsphil> yay, ATLAS/No GPS
[19:36] <cuddykid> ok, thanks

[19:37] <fsphil> which hell mode?

[20:42] <jonsowman> just wondering - what do people normally go for wrt number of decimal places for bearing and speed?
[20:42] <jcoxon> 4 decimal places iirc
[20:42] <jonsowman> can the tracker acceept anything?
[20:42] <jcoxon> yeah
[20:42] <jonsowman> is 1dp for each ok?
[20:43] <jonsowman> first time i've written something to be decoded by the tracker - don't know it's intricacies yet
[20:43] <jcoxon> oh right
[20:43] <SpeedEvil> 0 even
[20:43] <jcoxon> oops i thought you meant lat/lon
[20:43] <jcoxon> oops
[20:43] <jcoxon> yeah none or 1
[20:43] <SpeedEvil> for bearing and speed, they are significantly inaccurate anyway
[20:44] <SpeedEvil> The argument could even be made for 1/10th
[20:44] <SpeedEvil> (that is to the nearest 10)

[20:55] <DanielRichman> Oh and is anyone enough of a Co-ax guru to know which is better: RG316 or RG174 for 434MHz?
[20:55] <DanielRichman> off th e top of their heads
[20:55] <jcoxon> i didn't try that
[20:55] <jcoxon> does it require X?
[20:55] <fsphil> nah
[20:55] <jcoxon> should i try it?

[21:03] <fsphil> jcoxon, what version? - GBRG was added a couple of releases ago
[21:03] <jcoxon> version of what?
[21:03] <fsphil> fswebcam
[21:04] <jcoxon> 20091224
[21:04] <DanielRichman> Any particular considerations I should make when buying flux?
[21:04] <fsphil> aye, you need at least 20100401 -- what distro? I'll give them a poke
[21:04] <jcoxon> ubuntu
[21:05] <fsphil> ah
[21:05] <fsphil> strange, debian are up to date
[21:05] <Randomskk> DanielRichman: things to consider include water soluble, no clean, rosin
[21:05] <Randomskk> other things include form, e.g. pen vs jelly
[21:05] <DanielRichman> Randomskk: what's your preferred method of flux application? are "flux pens" ok?
[21:05] <Randomskk> depends on the task
[21:05] <Randomskk> I use flux pens a /lot/
[21:05] <DanielRichman> tqfp44
[21:05] <Randomskk> I use flex jelly rarer, but it's super useful when I use it
[21:05] <Randomskk> it's much stickier so holds awkward things in place
[21:06] <Randomskk> tbh tqfp44 would probably be fine with just the pen
[21:06] <Randomskk> but the jelly would help somewhat
[21:06] <Randomskk> definitely get a pen
[21:06] <Randomskk> they are super duper useful
[21:06] <DanielRichman> cool. I'm not going to use one of these up http://uk.farnell.com/circuitworks/cw8100/dispensing-pen-no-clean-flux/dp/130692 anytime soon?
[21:06] <DanielRichman> ie. I don't need to buy many
[21:06] <Randomskk> I've not bought a second
[21:06] <DanielRichman> excellent :) thank you
[21:07] <fsphil> those flux pens are brilliant
[21:07] <Randomskk> worth bearing in mind that no clean flux is a little different chemcially, but the lack of cleaning required is probably worth it for many cases
[21:07] <Randomskk> I can rarely be bothered cleaning flux off

[21:11] <Randomskk> debian was like once a leap year
[21:11] <fsphil> jcoxon, is the room dark or just bad webcam?
[21:11] <jcoxon> bad webcam
[21:11] <fsphil> yea seen a few of those
[21:11] <jcoxon> also the room varies a bit
[21:12] <fsphil> run fswebcam with --list-controls, see if anything is tweakable. you might be able to ramp up the contrast a bit
[21:15] <jcoxon> how to i tweak the contrast?
[21:15] <fsphil> use --set <name of control>=<what you want it at>
[21:16] <fsphil> the names vary from webcam to webcam
[21:16] <fsphil> use whatever --list-control says
[21:19] <Randomskk> jonsowman: each successive trace gets more and more convoluted
[21:22] <jcoxon> fsphil, hmmm it seems to resize the image automatically
[21:22] <jcoxon> and ignores -r
[21:24] <fsphil> means the camera can't support that resolution
[21:24] <fsphil> what size is it getting?
[21:24] <jcoxon> Adjusting resolution from 384x288 to 176x144.
[21:25] <fsphil> hmm, that's a bit small
[21:26] <jcoxon> a tiny bit :-)
[21:26] <fsphil> ahh, I bet the bigger sizes are compressed -- I haven't added that yet
[21:26] <jcoxon> oh right
[21:28] <jcoxon> fsphil, i reckon i'll need to add a light source and use black card to stop external light
[21:28] <DanielRichman> doesn't the ft790 have a backlight?
[21:28] <jcoxon> yeah it does

[21:37] <cuddykid> Worcester
[21:38] <cuddykid> I was thinking about coming down to cambridge but especially after last weeks trip (which it took 5 hrs to get back!!) I think I'll launch from here
[21:38] <DanielRichman> yeah I was about to say... we're slightly closer to camb though
[21:38] <DanielRichman> 5 hours!?
[21:39] <cuddykid> yes! It was a nightmare journey! Lots of accidents :(
[21:39] <cuddykid> went down to the uni :)
[21:41] <LazyLeopard> Happens. Had something similar last time I went up to Cambridge. Two hours there, Five hours to get home, partly because of an incident which closed the M11, and then because the Blackwall Tunnel was closed just before I got to it...
[21:42] <cuddykid> LazyLeopard, yeah, very similar situation!
[21:42] <cuddykid> anyone know about the notam then?
[21:45] <DanielRichman> rjharrison was working on his own local notam
[21:46] <DanielRichman> but apart from that I don't know :(
[21:46] <DanielRichman> you probably want to phone someone up cuddykid
[21:46] <cuddykid> ok, will give them a ring tomorrow :)
[21:46] <jcoxon> you want to chat with David Miller
[21:47] <cuddykid> too late for launch before hols (29th Jul) so will have to launch sometime after (mid-late Aug)!
[21:48] <Hiena> Bleh, an i thought this day couldn't go worst. At morning had to go for a blood test, spent half day wiring some connector, at evening lay quater qubic meter concrete for the new engine test facility, and just got a news from an airplane accident in Budapest.
[21:49] <jcoxon> not a good day at all

[21:50] <Hiena> Ah, and found out my new meds major component used as drug in the US, for horses...

[21:56] m1x10 (~mixio@62.38.17.59) left irc: Client Quit
[21:56] <Hiena> Btw, i'm almost done the new PIC-o-satellite design. It will be somekind of Sputnik remake. 1W tx power at tne bottom of the 180m band, beeping the local temperature and the voltages on morse.
[21:57] cuddykid (~acudworth@78.150.61.201) left irc: Quit: cuddykid
[21:57] <Hiena> Also, it would powered with 4 solar cell and a single 3V coin cell.

[22:03] <Hiena> Anybody will be interested to hitch it a ride for a high altitude test? That case i'll design some external control.
[22:04] <jcoxon> Hiena, can't fly 180m band in the UK unfotunately
[22:04] <Hiena> 27MHz?
[22:05] <russss> can't fly anything which requires a license
[22:07] Action: russss goes outside to attempt to take some photos of the ISS
[22:07] <Hiena> 27MHz is a CB which not requires any licence in the most country.

[22:08] <russss> ah true
[22:08] <russss> it's probably still not allowed :P
[22:11] Action: LazyLeopard nips out to see whether there's a clear enough sky for ISS spotting
[22:11] <Hiena> Which band you use? 70 cm?
[22:12] <m1x10> jcoxon, is there a datasheet on the web fo rFSA03? That from falcom does not work.

[22:19] <russss> that was a good ISS pass
[22:20] <LazyLeopard> Caught brief glimpses of it through cloud...
[22:20] <LazyLeopard> ...but it's real bright these days. ;)
[22:23] <Hiena> Are they welding something up there? ;)

[22:33] <russss> just coincidence
[22:34] <russss> in a good position for europe at the moment
[22:34] <russss> tomorrow is the last good one for a few months now, at least from London

[22:37] <russss> I bet the astrometry solver can't get those ones.
[22:37] <russss> but I'll give it a try.
[22:39] Action: LazyLeopard must check predictions. There's a high daylight pass tomorrow peaking near zenith about 21:06 BST, which might be near enough to sunset for ISS to be learly visible.
[22:41] <LazyLeopard> Wednesdays at about 19:57 BST will probably be in too much daylight.
