[05:47] <SamSilver> The visual rate is usually about 15 per hour, but the radio burst rate could be many times higher depending on the sensitivity of your receiving equipment.
[05:48] <SamSilver> The peak of this shower will occur on the morning of April 22, and the Earth will exit the Lyrids meteor stream on April 25.

[06:17] <jcoxon> atlas2 still running :-)
[06:18] <SamSilver> well done james
[06:18] <SamSilver> spot?
[06:18] <jcoxon> SamSilver, its just in the garden :-)
[06:18] <jcoxon> yeah
[06:18] <jcoxon> about 4 messages an hour
[06:19] <SamSilver> I had a look see at the live feed back from atlas2
[06:19] <jcoxon> see anything? in night mode txing is a lot more sparse
[06:20] <SamSilver> it was yesterday morning, I did not keep the url
[06:20] <griffonbot> @jamescoxon: atlas2 still running after 24hrs, SPoT getting approximately 4/6 messages an hour through, coming up to the SPoT refresh #atlasballoon [http://twitter.com/jamescoxon/status/60588614081445888]
[06:20] <jcoxon> http://bit.ly/hqdun5
[06:21] <SamSilver> this is great work
[06:22] <SamSilver> shame - maybe take it for a walk around the garden, must be bored with same lat long
[06:22] <jcoxon> the only thing that isn't being tested is the crystal heater
[06:22] <jcoxon> which i fear will draw quite a bit of current
[06:23] <SamSilver> home made oven?
[06:23] <Darkside> jcoxon: at some point i need to talk about the remote dl-fldigi stuff you have going there
[06:23] <Darkside> it'd be very useful for the remote RX station juxta is setting up
[06:23] <jcoxon> SamSilver, its a resistor heater with a temp sensor over the radio crystal with a PID controller
[06:24] <jcoxon> Darkside, yeah its quite simple - the key changes have actually been made to dl-fldigi
[06:24] <Darkside> cool
[06:24] <jcoxon> need to update the rig control as I now use hamlib
[06:24] <SamSilver> I have been looking at a few designs myself
[06:24] <Darkside> it'd be better than what we were planning to do, which was to use VNC
[06:24] <fsphil> you've added ft790 support to hamlib? haha
[06:24] <jcoxon> fsphil, ft817
[06:24] <fsphil> aah
[06:24] <Darkside> woo FT817
[06:24] <fsphil> I thought you where still using the 790 :)
[06:24] <Darkside> we're gonna be using a funcube dongle :P
[06:25] <jcoxon> Darkside, have you seen that the waterfall is clickable? :-p
[06:25] <fsphil> ooh Darkside, that's supported in hamlib now too. seems to work but the frequency is offset
[06:25] <Darkside> didnt see that
[06:25] <Darkside> but awesome
[06:25] <Darkside> fsphil: yeah
[06:25] <Darkside> you cant set the freq correction
[06:25] <Darkside> but it can be hardcoded in
[06:25] <jcoxon> Darkside, when i get a moment i'll package it all up and stick it on GIT
[06:26] <Darkside> in my case -21 works well
[06:26] <jcoxon> github*
[06:26] <Darkside> cooool
[06:26] <jcoxon> as i think it needs to be 'developed'
[06:26] <jcoxon> its a pretty dirty hack
[06:26] <jcoxon> fsphil, http://share.findmespot.com/shared/faces/viewspots.jsp?glId=02vhBoDslO1BaEqCUR9sUikleajn0x2u4
[06:28] <fsphil> getting crowded there!
[06:28] <fsphil> the coordinates making sense?
[06:28] <jcoxon> yeah, they fit
[06:29] <jcoxon> the variation is the slight altitude changes
[06:29] <jcoxon> its going to make interesting patterns
[06:30] <eroomde> morning
[06:30] <jcoxon> hey eroomde
[06:32] <jcoxon> fsphil, so we are now getting to the end of 24hrs with the spot in tracking mode - it should stop tracking after 7.34
[06:32] <jcoxon> then the spot arduino will detect that it hasn't requested GPS data in 15mins and restart the tracking mode
[06:32] <jcoxon> fingers crossed
[06:37] <eroomde> what's the plan jcoxon ?
[06:42] <fsphil> aah to spot automatically stops after 24 hours
[06:45] <jcoxon> fsphil, its meant to yes
[06:45] <jcoxon> eroomde, so i've been running atlas2 outside now for 24hrs
[06:45] <jcoxon> spot sends a lat/lon/alt encoded in lat/lon
[06:45] <jcoxon> and we get about 4 messages an hour from my garden
[06:47] <eroomde> ok
[06:47] <jcoxon> i'm thinking in the air that might rise up to 5 out of 6
[06:48] <jcoxon> should be enough for us to keep tabs on it when it falls out of radio range
[06:48] <eroomde> yup
[06:48] <jcoxon> and then the 434 tx'er has a similar schedule to the picoatlas flight
[06:49] <jcoxon> so first 500 strings continous
[06:49] <jcoxon> then in the day it there are small gaps when the radio is shutdown but gps is kept on
[06:49] <jcoxon> then at night gps gets shutdown for 10mins then restarted , 10 tx strings and repeat
[06:50] <eroomde> let's hope though it doesn't freeze up this time!
[06:50] <jcoxon> indeed
[06:50] <jcoxon> will have better insulation :-p
[06:50] earthshine (~mike@cpc2-orpi1-0-0-cust69.2-3.cable.virginmedia.com) left irc: Ping timeout: 252 seconds
[06:51] <jcoxon> also its a better ublox - i wonder if the new models would cope better with drift etc
[06:51] earthshine (~mike@cpc2-orpi1-0-0-cust69.2-3.cable.virginmedia.com) joined #highaltitude.
[06:52] <eroomde> is it an integrated module and antenna unit?
[06:52] <jcoxon> its a gpsbee with external antenna
[06:52] <eroomde> ah cool
[06:52] <jcoxon> going to place it all inside the box though
[06:53] <jcoxon> works fine through the insulation
[06:53] <eroomde> so you can keep the mudule toasty inside the box
[06:53] <jcoxon> also for this payload the box will have no holes at the bottom
[06:53] <jcoxon> the only hole will be for the radio antenna to come out which will loop out the top
[06:54] <jcoxon> so it'll float for a while
[06:54] <jcoxon> (the spot will allow us to potentially track it
[06:54] <jcoxon> )
[06:57] <eroomde> is this for a launch whilst n-trizzle is here?
[06:57] <jcoxon> i'm off the week before he gets here
[06:57] <jcoxon> so i was thinking of doing a normal flight first to test the payload
[06:57] <eroomde> for the duration of his stay?
[06:57] <jcoxon> as we haven't flown spot in this configuration before
[06:57] <eroomde> ah ok
[06:57] <eroomde> yeah fair enough
[06:57] <eroomde> so what week would that be?
[06:58] <jcoxon> then depending on the weather perhaps do a floater when he is here
[06:58] <eroomde> i'm back in the 30th
[06:58] <eroomde> away from friday
[06:58] <jcoxon> so i'm off the week starting 2 may
[06:58] <jcoxon> oh wait
[06:58] <jcoxon> no i'm not
[06:58] <jcoxon> week 9 May
[06:59] <jcoxon> so normal flight between 9-12 may
[06:59] <jcoxon> natrium is here 14/15/16 May
[06:59] <jcoxon> perhaps pinhole floater then
[06:59] <eroomde> ok cool
[06:59] <jcoxon> work for you?
[07:00] <eroomde> yup should do
[07:00] <jcoxon> now just need the weather to play ball
[07:01] <eroomde> though potentiually could be quite busy with work from the 9th to the 12th
[07:01] <eroomde> depends on the weather too
[07:01] <eroomde> if the winds are low we might be flying the blimp those three days
[07:01] <jcoxon> i'm sure i can recruit jonsowman and Randomskk
[07:01] <jcoxon> just be a simple launch, up down, recover
[07:02] <eroomde> they might have tripos!
[07:02] <eroomde> leroy won't like it if they take a break
[07:02] <jcoxon> fine! i'll get steve :-p
[07:07] <jcoxon> hmm perhaps it does keep tracking after 24hrs
[07:19] <Randomskk> our exams start 6th june :P
[07:20] <jcoxon> loads of time
[07:20] <eroomde> gosh that's latre

[09:49] <fsphil> 2.54mm isn't it?
[09:50] <fsphil> or 0.1 inches
[09:51] <NigelMoby> Oki, and socket spacing is .3"?
[09:54] <fsphil> probably, but the datasheet will say
[09:55] <NigelMoby> Yup, now let's see if maplins are useful
[10:01] <NigelMoby> Omg
[10:01] <NigelMoby> They have 1

[11:46] <Laurenceb_> anyone here come across evostick spray adhesive?
[11:47] <Laurenceb_> im worried its a spray version of their contact adhesive, thats rather thick visous stuff you never want near a pcb
[11:47] <GW8RAK> I've come across it as a glue for promotional photos etc.
[11:47] <Laurenceb_> ever used it?
[11:48] <GW8RAK> i.e not meant for heavy duty usage and non marking.
[11:48] <GW8RAK> Did use it many years ago. Did the job.
[11:48] <Laurenceb_> hmm if thats so its probably ok
[11:49] <Laurenceb_> ive used evostick contact adhesive for repairing worktops - its not something you want near a pcb
[11:49] <GW8RAK> IIRC, it's a stronger version of post-its glue

[12:10] <hibby> Please, come and join us on the KDE side of things :)
[12:10] <hibby> 4.6 is incredibly usable
[12:11] <Laurenceb_> hard to see how it could be improved apart- at least if you avoid really widescreens
[12:11] <Laurenceb_> then they just completely wreck it
[12:12] <fsphil> I may try XFCE
[12:12] <Laurenceb_> me too
[12:12] <Laurenceb_> i used to run it before ubuntu
[12:13] <hibby> xfce 4.8 is also lovely... As is LXDE.
[12:13] <hibby> Anyone tried xmonad?

[12:33] <hibby> say what you want about gnome 3... It's quite pretty
[12:33] <fsphil> never tried LXDE yet, but I'm downloading the live image
[12:33] <hibby> it's not instantly intuitive, though
[12:33] <hibby> but I'm a KDE4 kinda guy.
[12:33] <fsphil> it's very pretty -- and works better on the multiple monitors than previous fedora releases
[12:34] <fsphil> but it's quite restrictive. you can't change anything but the background
[12:34] <hibby> Indeed. Fedora KDE4 has, since 12 at least, supported my dual head setup in the office here

[12:36] <Randomskk> I used kde for ages, then a few months into kde4 installed vanilla ubuntu and have been on gnome since
[12:36] <Randomskk> it kind of just worked fine for what I needed better I guess, though I miss all the options I don't miss some of the arcane weird things?
[12:36] Action: Randomskk is really tempted by xmonad or awesome
[12:39] <hibby> i just don't feel the need for that much data on screen at once
[12:39] <Randomskk> yea
[12:40] <Randomskk> with my netbook maybe that would have been more important but my new macbook air is sticking with os x for now and that's fine; my desktop is a dual 1900x1200 setup so loads of space anyway
[12:40] <Randomskk> plus I generally just fullscreen a terminal running vim and then have a few others for git/testing/whatever on the second screen
[12:41] smea (~smealum@85-170-62-251.rev.numericable.fr) left irc: Ping timeout: 276 seconds
[12:41] <hibby> ooh, jealous of the air
[12:41] <hibby> I really could do with another monitor at home
[12:41] <Randomskk> the air's so nice, I put myself back into overdraft getting it but it's worth it :P
[12:42] <Randomskk> beats the crap out of my previous tiny netbook in that the keyboard's big enough to actually work on
[12:42] <Randomskk> but it's also stupid thin and light so I'm happy taking it anywhere
[12:42] <fsphil> I love my thinkpad's keyboard
[12:42] <Randomskk> I was torn between the macbook air and the ultraportable thinkpads
[12:42] <fsphil> and the built-in LED light above the screen
[12:42] <hibby> Aye. I'm tempted for an ipad, or similar, for my american trip... I suspect that my HP TC1100 may be a bit heavy for the whole thing
[12:43] <Randomskk> fsphil: probably one of their X series or something, they do have amazing keyboards
[12:44] <Randomskk> plus were generally more powerful
[12:44] <Randomskk> but at the end of the day much bigger and heavier
[12:44] <fsphil> (I once carried a Toshiba Toughbook around London -- I would have been *happy* for someone to nick it, it was that heavy)
[12:44] <Randomskk> my main selection criteria was portability so the air kind of beat everything else right from the start
[12:45] <Randomskk> where I guess portability is a strong function of thickness, a fairly strong function of width, and also a reasonable function of weight?
[12:45] <hibby> aye.
[12:46] <fsphil> does it have those glossy screens apple seem so fond of?
[12:46] <Randomskk> yes :/

[13:24] <eroomde> it was before I knew haskell though so I found making custom configurations a bit tricky
[13:24] <eroomde> it's nice, but i'm not sure that 100% screen utilisation is actually something i'm particularly bothered about

[13:26] <Laurenceb_> yes
[13:27] <Randomskk> didn't know you typically stuck them down, everything I've seen done (admittedly all hobbyist) uses clamps or hands
[13:27] <eroomde> poster spray
[13:27] <eroomde> that 3M stuff
[13:27] <Laurenceb_> ah thats what ive ordered

[13:31] <Laurenceb_> yeah
[13:32] <Laurenceb_> i have a very nice one with low flow, ive put a 25mm nozzle on and its perfect
[13:32] <Laurenceb_> big enough to reflow the lsm303dlh, itg3200 and bmp085 at one go

[13:33] <Laurenceb_> not all no
[13:33] <Laurenceb_> theres about 8 passives still to go on
[13:34] <Laurenceb_> and the vreg and bjt transistor
[13:35] <Laurenceb_> tho ideally i want to solder that first and test the power supply sequencing... slightly annoying

[19:26] <SpeedEvil> I'm idly wondering about solar collectors.
[19:27] <Laurenceb> hmm not crazy prices
[19:27] <Laurenceb> way cheaper than ive seen it
[19:27] <SpeedEvil> yeah, good prices.
[19:27] <SpeedEvil> They will also send samples
[19:27] <SpeedEvil> I got a bag with 4 different sorts to play with - 10*5cm or so
[19:28] <NigeyS> ok put a reset led on there, it def works james, must be the timing thing again

[19:31] <SpeedEvil> Laurenceb: The internet sales model seems to make it possible for very, very small firms to do deliveries of big stuff nationwide - which is doing interesting things.
[19:32] <SpeedEvil> For example, them and seconds both use their own lorries.

[19:48] <hibby> yep
[19:48] <fsphil> sweet
[19:48] <fsphil> I was worried the last 'launch' would have put them off :)

[20:04] <Upu> oh yeah
[20:04] <fsphil> this one is 4800 baud and 2 stop bits

[21:57] <jcoxon> i think if hamlib is polling the ft817 and you try and turn it on it locks
[21:57] <fsphil> that was it
[21:57] <jcoxon> i actually think it might be a 817 bug
[21:57] <Upu> wish I could find a serial port monitor for Windows 7 64 bit so i can work out what process is holding the serial port open
[21:57] <jcoxon> NigeyS, ooo looks good

[22:34] <fsphil> sweet.. funcube dongle + hamlib = frequency tracking in dl-fldigi
[22:36] <NigeyS> schweeeeeeeet
[22:46] <Darkside> fsphil: noice
[22:47] <fsphil> few more bad checksums compared to the 817, but otherwise working well
[22:47] <Darkside> i tried compiling hamlib, bur it sidnt seem to be compiling in funcube support
[22:47] <SpeedEvil> Interesting to compare them on a 'real' launch
[22:48] <Darkside> fcd.c was there, but not showing up in the list
[22:48] <fsphil> on this machine I just took the hamlib source RPM, and replaced the tarball with the new version
[22:48] <fsphil> it's listed as "amsat-uk funcube dongle"
[22:48] <Darkside> mm
[22:48] <fsphil> took me ages to find it, kept looking under F
[22:48] <Darkside> ill try again
[22:49] <fsphil> shame fldigi can't do more than 4khz at a time
[22:49] <fsphil> would be neat to do 9600 baud :)
[22:50] <Darkside> haha
[22:50] <Darkside> 1200 would be good enough
[22:51] <SpeedEvil> Laurenceb_: When you were poking at fldigi - did it seem easy to up the sample-rate? I seem tor ecall you commented it was rather fixed in a number of places
[22:51] <fsphil> 1200 works but I'd be wary of using on a launch just yet
[22:51] <Elwell> ah cool - hamlib's been updated for dongle?
[22:51] <fsphil> Elwell, yups .. new version out last week
[22:51] <Elwell> great
[22:53] <Darkside> awesome
[22:53] <Darkside> i might try compiling it in my postgrad ubductiin
[22:54] <Darkside> induction*
[23:00] <Darkside> fsphil: 1.2.13?
[23:00] <SpeedEvil> What's funcubes IF and samplerate?
[23:00] <fsphil> that's the one
[23:00] <Darkside> hmm
[23:00] <Darkside> SpeedEvil: no if
[23:00] <Darkside> direct conversion afaik
[23:00] <SpeedEvil> I mean sample band width.
[23:01] <Lunar_Lander> btw I talked to the guy who dislikes the arduino
[23:01] <Darkside> 96KHz sample sate
[23:01] <Darkside> I/Q
[23:01] <Lunar_Lander> he criticizes that it can only do 8 bit and can't really calculate
[23:01] <Lunar_Lander> those were his words
[23:01] <Darkside> so ~80KHz BW after
[23:01] <SpeedEvil> Lunar_Lander: Fail.
[23:01] <Lunar_Lander> and he suggested "BeagleBoard"
[23:01] <fsphil> Lunar_Lander, don't listen to him
[23:01] <Darkside> pfffff
[23:01] <Lunar_Lander> but BeagleBoard is 5 times more expensive
[23:01] <Darkside> beagleboard is overpowered for basic telemetrey
[23:01] <SpeedEvil> Lunar_Lander: You can do arbitrary precision or floating point on 8 bit platforms with no problem.
[23:01] <Lunar_Lander> yeah
[23:02] <SpeedEvil> Just slowly.
[23:02] <SpeedEvil> Well - 'slowly'
[23:02] <SpeedEvil> Slowly in computer terms.
[23:02] <Lunar_Lander> yeah
[23:02] <fsphil> my avr's are doing quite a bit of bit crunching
[23:02] <Lunar_Lander> I mean when i saw the beagleboard
[23:02] <SpeedEvil> Maybe a few tens of thousands of floating point divisions a second
[23:02] <Lunar_Lander> I thought "What? 720 MHz CPU?!"
[23:02] <Lunar_Lander> we got a PC from 2000 here
[23:02] <fsphil> my only complaint is the lack of memory :)
[23:02] <Lunar_Lander> it has a 650 MHz Pentium III
[23:02] <Lunar_Lander> so that beagleboard is even faster?
[23:03] <Darkside> beagleboard is ARM
[23:03] <Darkside> different architecture
[23:03] <Lunar_Lander> yea
[23:03] <Lunar_Lander> it sounds like a little PC to me
[23:03] <Lunar_Lander> as it can do HD video and stuff like that
[23:04] <Darkside> mm
[23:04] <Darkside> its a nice board
[23:04] <Darkside> but overpowered for this paplication
[23:04] <Darkside> maybe if you wanted to do some really advanced stuff
[23:04] <Darkside> but not for positioning and temperature
[23:04] <SpeedEvil> http://cgi.ebay.co.uk/Mini-STM32-Board-STM32F103VCT6-3-2-LCD-Touch-Panel-JTAG-/190506664508?pt=LH_DefaultDomain_0&hash=item2c5b15023c

[23:05] <Lunar_Lander> I mean
[23:05] <Lunar_Lander> the Mega 2560 can do quite a few sensors I assume?
[23:05] <Darkside> of course
[23:05] <Darkside> depending on what tupe of sensor you use, a standard arduino would be fine too
[23:05] <TangoAlpha> mega2560 is what i am using
[23:05] <Darkside> i.e. the DS18B20 temp sensors can all go on one bus
[23:06] <TangoAlpha> i have temp x 2, humidity, pressure, 3d accelerometer, gps
[23:06] <Darkside> noice
[23:06] <Lunar_Lander> yeah
[23:06] <Darkside> accelereometer on a HAB?
[23:06] <Lunar_Lander> I thought of this
[23:07] <Lunar_Lander> GPS->Uno->NTX2
[23:07] <Lunar_Lander> and
[23:07] <Darkside> what sample rate are you using on teh accelerometer?
[23:07] <TangoAlpha> it's also doing the radio and cellular traffic (sms and hopefully http soon too)
[23:07] <Lunar_Lander> Sensors->Mega 2560->OpenLog
[23:07] <SpeedEvil> http://cgi.ebay.co.uk/Mini-STM32-Devlopment-Board-STM32F103VET6-JTAG-/190500913782?pt=LH_DefaultDomain_0&hash=item2c5abd4276 - hmm - interesting - cheap
[23:08] <TangoAlpha> accelerometer sample rate is 0.5hz
[23:08] <Darkside> thats not going to be a huge help
[23:08] <jonsowman> hibby: more than my real name gets used :P
[23:08] <TangoAlpha> it's still a work in progress
[23:08] <Darkside> TangoAlpha: whats your aim with the accelerometer
[23:08] <TangoAlpha> no idea
[23:08] <Darkside> are you trying to look at the motion of the payload?
[23:08] <TangoAlpha> i just happened to have one
[23:09] <Darkside> exactly
[23:09] <Darkside> its not very useful
[23:09] <Darkside> bbl, postgrad bullshit session^W^W induction
[23:09] <TangoAlpha> i'll probably up the sample rate later, at the moment it was just a matter of getting everything to work together
[23:09] <Lunar_Lander> so accellerometer can be removed from the list?
[23:10] <TangoAlpha> i've routed a pcb with all the sensors listed so i plan to have them on board
[23:10] <TangoAlpha> how much use they'll be is something else entirely
[23:11] <TangoAlpha> i do know that the accelerometer can detect free fall so if nothing else i will use it to detect a state change
[23:11] <SpeedEvil> Are they accurate enough to pick up G dropping?
[23:11] <TangoAlpha> it's an adxl345
[23:22] <Lunar_Lander> so you don't need an accelerometer Darkside ?
