[00:00] <fuzzylugnuts> Edwardo
[00:00] <rharrison1971> edmoore: You in a fit state?
[00:01] <edmoore> I think I will be awake for just a few seconds longer
[00:02] <rharrison1971> edmoore: Can you get those switching t/f's in a normal dip pinout?
[00:02] <edmoore> I have not seen any...
[00:02] <rharrison1971> Ok cool
[00:02] <edmoore> but have not looked extensively
[00:03] <rharrison1971> I'll bend the bugger into the board
[00:03] <edmoore> i would be interested in them too if they existed
[00:03] <edmoore> :)
[00:03] <fuzzylugnuts> oh, ed... the atmospheric disturbance/diffusion guys are going to help me a bit
[00:04] <edmoore> oh cool - for modelling?
[00:04] <rharrison1971> I'm going to power it with 9v as I needs it to kick out 5.0v and Vin 1.1V>Vout
[00:05] <fuzzylugnuts> edmoore: I just need to get data from them, like... temperatures and jet stream elevation, etc... I don't know what I could model
[00:05] <rharrison1971> Either 5aaa's or 1PP3
[00:05] <edmoore> rharrison1971: ok, stands to reason
[00:05] <edmoore> see how long she runs on a pp3
[00:06] <rharrison1971> Should be plenty long enough though proof is in the pudding
[00:06] <edmoore> fuzzylugnuts: well, if you know that, you can do all the prediction you want :)
[00:06] <rharrison1971> nights all
[00:06] <fuzzylugnuts> edmoore: win!
[00:06] <fuzzylugnuts> 'night
[00:06] <edmoore> g'bnight rharrison1971
[00:06] <edmoore> me too, infact

[00:20] <Laurenceb_> hello
[00:20] <fuzzylugnuts> Hey
[00:21] <jcoxon> evening Laurenceb_
[00:21] Action: Laurenceb_ finally has a winch servo drum
[00:21] <Laurenceb_> I'vwe got all the parts to finish off my mini rogallo now
[00:26] <fuzzylugnuts> yay?
[00:26] <Laurenceb_> well its still got to be assembled
[00:26] <fuzzylugnuts> ah
[00:26] <Laurenceb_> in hindsight its an annoying design
[00:26] <Laurenceb_> everything is encased in a block of blue foam
[00:26] <Laurenceb_> which is good in all respects apart from ease of construction
[00:26] <Laurenceb_> I'm having to use a thin blade to cut out for the various parts
[00:27] <Laurenceb_> basically I started with a 34mm thick sheet, sliced off one side 6mm thick
[00:28] <Laurenceb_> then started "milling" out in the remaining 25mm or so for the boards, batteries, servo ect
[00:28] <Laurenceb_> which is easier said than done
[00:28] <fuzzylugnuts> got pictures?
[00:29] <Laurenceb_> fraid not
[00:29] <Laurenceb_> hopefully it will look pretty in a day or so :P
[00:30] <fuzzylugnuts> Ok
[00:30] <Laurenceb_> oh the radio and flight computer boards are on the wiki - http://wiki.ukhas.org.uk/_media/projects:imgp0103.jpg?cache=cache
[00:31] <Laurenceb_> I've replaced the 4xAA with lipo and a smps
[00:32] <Laurenceb_> and the servo is now a digital futaba with winch drum
[00:35] <fuzzylugnuts> that radio transmitter is so cute.
[00:36] <Laurenceb_> yeah, pity about my piss poor soldering
[00:36] <fuzzylugnuts> do you have a convection oven?
[00:36] <Laurenceb_> no, cant you tell :P
[00:36] <fuzzylugnuts> it was a subtle way to suggest
[00:37] <Laurenceb_> oh yes... I need to rewrite the firmware for the radio module
[00:37] <Laurenceb_> so many jobs to do :-/
[00:38] <fuzzylugnuts> yeah, its hard doing everything yourself
[00:39] <Laurenceb_> actually I was looking at writing a reciver to run on an arduino
[00:40] <Laurenceb_> I find RTTY a bit annoying
[00:40] <fuzzylugnuts> to decode?
[00:40] <Laurenceb_> yes
[00:41] <Laurenceb_> impleneting a FLL and DLL running from ADC interrupts perhaps...
[00:41] <fuzzylugnuts> you coyuld probably swipe the modem code from "gmfsk" or some open source digi project
[00:41] <Laurenceb_> yeah
[00:41] <Laurenceb_> but I really want the low level tracking loops writing from scratch
[00:42] <fuzzylugnuts> *nods*
[00:42] <fuzzylugnuts> yeah, that has an appeal
[00:42] <Laurenceb_> and personally I find the prospect of that sort DSP running on a PC using a sound card unappealing
[00:42] <Laurenceb_> much better to have a uC doing it with its ADC
[00:43] <fuzzylugnuts> well yeah, if thats what you want
[00:43] <Laurenceb_> it could autotune the radio and pump bytes out of the usb
[00:44] <Laurenceb_> but .... I'd need a scanner first :/
[00:44] <jcoxon> Laurenceb_, hehe
[00:44] <Laurenceb_> ah
[00:45] <Laurenceb_> jcoxon: you would be in a perfect position to test the firmware :P
[00:45] <jcoxon> really?
[00:45] <Laurenceb_> you have arduino and scanner?
[00:45] <jcoxon> i have an arduino and i have a ft-790r reciever
[00:46] <Laurenceb_> can you tune the ft-790r using the mic port?
[00:46] <jcoxon> yup
[00:46] <Laurenceb_> I remember you saying something about using a servo?
[00:47] <jcoxon> oh you can do it through the mic port as well
[00:47] <jcoxon> i've got a socket and some optoisolators
[00:47] <jcoxon> just pull pin 7 to ground goes up the freq one step
[00:47] <jcoxon> and pin 6 to ground takes it down one step
[00:48] <Laurenceb_> optoisolated sounds like a good move
[00:48] <jcoxon> for once in my life i'm planning ahead :-p
[00:48] <Laurenceb_> I've been reading some books on DSP, its got me excited
[00:50] <Laurenceb_> so yeah, at some point I'll take a look at getting some code running, but I'm just trying to work out the basics atm
[00:51] <jcoxon> i've got a pretty good setup right now with truetty

[01:04] <fuzzylugnuts> oh man, I am soooo tempted to get some of those flat-pack capacitors
[01:06] <fuzzylugnuts> then I thought.... it doesn't matter if this transmitter is small and cute, because I'm never going to get it back
[01:17] <Laurenceb_> hehe
[01:20] <Laurenceb_> grrr theres nothing about selftest over spi on the latest mlx90609 datasheet
[01:20] <Laurenceb_> I dont get it - it used to support it
[01:20] <Laurenceb_> oh well I'd better get some sleep, cya

[09:25] <edmoore> greetings
[09:26] <rharrison_quiet> Morning sir
[09:26] <rharrison_quiet> Didn't get to bed in the end untill 1:40 am
[09:26] <rharrison_quiet> Got that converter soldered in on the MK1
[09:27] <rharrison_quiet> switching t/f
[09:27] <edmoore> oh cool - she works?
[09:27] <rharrison_quiet> It runs warm with a 9v conversion to 5.00
[09:27] <rharrison_quiet> But absolutly accurate
[09:27] <rharrison_quiet> with a 1% resisiter
[09:27] <rharrison_quiet> resistor
[09:28] <rharrison_quiet> May try 5xAAA
[09:28] <rharrison_quiet> Interesting battery box that one
[09:29] <edmoore> whats the configuration?
[09:29] <rharrison_quiet> I guess the less change in voltage the greather the efficiency
[09:30] <rharrison_quiet> 9v PP3 -> 5.00 v for lassen SKII, ATMega8 & Radiometrix
[09:30] <rharrison_quiet> MKII will be 3.3v for the iQ, ATMega8L, and Radiometrix
[09:31] <edmoore> sounds awesome :)
[09:31] <edmoore> I have the cnc bug
[09:32] <edmoore> after building stuff on a cnc router yesterday, it's just such a wonderful tool to have
[09:33] <rharrison_quiet> They're cool. I don't have one of those in the garage
[09:33] <rharrison_quiet> But would be v usfull
[09:33] <edmoore> no, me neither. of only.
[09:34] <rharrison_quiet> right I'm on with the day job. Looking forward to the 4th Oct
[09:34] <edmoore> we didn't really stretch it, we just picketed out holes fro disk magnets and a steel plate to go across the top of them to make a better magnetic circuit between car and box
[09:34] <edmoore> but it made it all within about 2 minutes
[09:34] <edmoore> ha, ok, will let you work :)

[10:10] <edmoore> morning gordonjcp
[10:16] <jcoxon> whats everyone up to today then?
[10:17] <ShellEvil> Fixing roofs, ponds, and sorting out bits for my houe.
[10:17] <edmoore> family day
[10:17] <edmoore> so no payload work in guildford
[10:17] <edmoore> the cnc router is luring me though
[10:18] <edmoore> you?
[10:18] <jcoxon> tis my day off
[10:18] <jcoxon> :-)
[10:18] Action: ShellEvil has been on a power-tooll spree.
[10:18] <edmoore> jcoxon: do you ever catch any of harry and paul?
[10:18] <edmoore> ShellEvil: there can be nothing more exciting :)
[10:18] <jcoxon> going to freshers fair, tescos and start abit of my super essay
[10:18] <edmoore> sessay
[10:19] <jcoxon> edmoore, yes though i'ts not as good as some of their earlier work

[10:19] <edmoore> jcoxon: I think you should aspire to be a Posh Surgeon
[10:19] <ShellEvil> Sort of a angle grinder, but reciprocating over 3 degrees, not rotating.
[10:19] <jcoxon> hehe
[10:19] <ShellEvil> So it's great for cutting up to edges.
[10:20] <edmoore> ShellEvil: a smart looking bit of kit! might show it to mum who is on a bit of a skirking board mania atm
[10:20] <ShellEvil> They are brilliant for that.
[10:20] <edmoore> skirting*
[10:20] <ShellEvil> Cutting right at a corner.
[10:21] <ShellEvil> And a post-hole digger for my fence. (petrol)
[10:23] <edmoore> suitably noisy?
[10:23] <ShellEvil> I assume so.
[10:23] <edmoore> :)
[10:24] <ShellEvil> I bought a manual one.
[10:24] <ShellEvil> But I then realised I have 40*6" holes to do.
[10:24] <ShellEvil> And that I can buy new and resell for what it costs to do 1 days hire.
[10:25] <edmoore> yeah
[10:26] <jcoxon> edmoore, when you back to cam?
[10:26] <edmoore> sporadically from the 25th, full time from the 2nd
[10:27] <jcoxon> okay, cool
[10:28] <edmoore> will be around for beaconhab, certainly
[10:28] <edmoore> though if the pair of you can really resist not putting a powershot on there, I will be very suprised indeed
[10:28] <jcoxon> hmmm the plan might be changing a little
[10:29] <edmoore> :p
[10:29] <edmoore> oh?
[10:37] <ShellEvil> I'm surprised at how fast full-frame cameras have come down in price.
[10:37] <edmoore> such as what?
[10:38] <ShellEvil> (though the 21MP canon thingy
[10:38] <ShellEvil> 4K or so
[10:39] <edmoore> oh yeah. impressive
[10:39] <edmoore> and the d700
[10:39] <edmoore> 2k
[10:44] <ShellEvil> Oops.
[10:44] <ShellEvil> I may have been meaning dollars.;
[10:47] Action: ShellEvil wonders if there will be such a thing as 'large format' digital emerging in the next few years.
[10:47] <edmoore> that would be in impressive piece of engineering
[10:48] <ShellEvil> I mean >35mm.
[10:48] <ShellEvil> Given that prices of 35mm will drop.
[10:48] <edmoore> yes
[10:48] <ShellEvil> medium format I mean.
[10:48] <edmoore> well there are medium format digital backs
[10:48] <ShellEvil> :)
[10:48] <edmoore> up in the 50+MP range
[10:48] <edmoore> but you pay for them....
[10:48] <ShellEvil> Yeah - they are marketed at nutters though essentially.
[10:48] <jcoxon> hmmmm, aparently there is a car bomb in oxford street
[10:48] <jcoxon> hasn't gone off but they are evacuating
[10:49] <gordonjcp> eep
[10:50] <jcoxon> hasn't yet appeared on any news websites yet though

[21:41] <edmoore> what's been the winner?
[21:41] <edmoore> dragon?
[21:41] <robert1971> I love the dragon it should have a cult following
[21:42] <edmoore> i'd love to have been at their office that day
[21:42] <edmoore> 'so... my new girlfriend makes swirly chinese-like computer art'
[21:42] <robert1971> To be honnest the Olimex was my fav. till last w/e when it wouldn't program the atmega8. I have been using the atmel avrispmk2 mainly cos it has a cover on it
[21:42] <edmoore> 'hey, you know that pcb we're working on...'
[21:43] <robert1971> The new badger?
[21:43] <edmoore> a dragon would probably beat a badger in a fight
[21:44] <robert1971> BTW My iphone just got activated. I'm going to write an applet to log to the tracker after my first launch of Icarus
[21:44] <edmoore> that sounds very cool, and useful
[21:47] <robert1971> Read this ed http://www.instructables.com/id/Help%3a-An-Absolute-Beginner_s-Guide-to-8-Bit-AVR-Pr/
[21:47] <robert1971> You could do this in your sleep
[21:49] <edmoore> already put the ZIP socket on mine :)
[21:50] <robert1971> I mean to do that when I get some time. I guess you just solder a chip holder onto the pcb and pull out the avr to prog. it
[21:51] <edmoore> yep.
[21:51] <robert1971> Saves messing with the isp stuff
[21:51] <edmoore> i prefer isp...
[21:51] <robert1971> I kept clear of sockets for the ballon incase the temp. upset them
[21:51] <edmoore> though that's mainly because everything i've done recently is smd
[21:51] <robert1971> More connections to go wrong
[21:52] <robert1971> smd's are so much smaller too
[21:52] <edmoore> indeed
[21:52] <robert1971> I'm going to print a beacon board at some point and I'm going to have the smd avr put at the printers
[21:53] <robert1971> put on
[21:53] <edmoore> henry (from cusf) just got these made up. black solder resist is nice... http://www.pericynthion.org/srv1x
[21:53] <edmoore> you can solder smd EEEEEASILY
[21:54] <edmoore> especially the multi pin packages. they're very much faster to do than the passives

[21:55] <edmoore> it's really not that bad - you can solder a row all at once
[21:56] <edmoore> rather than individual pins
[21:56] <edmoore> you just put a smallish blob on the tip of the iron and drag it down a row
[21:56] <edmoore> you need to apply plenty of flux with a pen before, but the soldering is a 3 second operation
[21:57] <robert1971> Any ideas on how to mount a board to the back of another. I want to put the gps skII on the back of the beacon board. Bit of card board between them or is there something better?
[21:57] <edmoore> if you get one or two bridges, just use a bit of solder wick to get rid of them.
[21:57] <robert1971> Plastic, antistatic foam
[21:57] <edmoore> not anti-static
[21:57] <edmoore> that's partially conductive
[21:58] <robert1971> I'll have a play at some point. You have convinced me to give the smd a go
[21:58] <edmoore> should never power stuff when it's on anti-static - it's designed for power off only
[21:58] <robert1971> Plastic sheet?
[21:58] <edmoore> that'd be fine, yeah
[21:58] <robert1971> Im glad I asked
[21:58] <edmoore> maybe some foam
[21:58] <robert1971> Normal foam
[21:59] <robert1971> Springy stuff
[21:59] <edmoore> yeah
[21:59] <edmoore> we use that in the payload boxes
[21:59] <robert1971> I have loads of that
[21:59] <edmoore> and usually wrap everything up in that and then space blanket on top. hey presto, insulated
[21:59] <robert1971> squish it beween the boards and tape them together!
[22:00] <robert1971> Electrical insulation tape :)
[22:00] <edmoore> perfect!
[22:01] <robert1971> The worst bit is the foam is pink
[22:03] <natrium42> lol
[22:03] <edmoore> Fabulous HAB
[22:03] <edmoore> Fab Hab
[22:03] <edmoore> shotgun!
[22:04] <jnd> hey
[22:04] <robert1971> Just the bit between the pcb.
[22:04] <natrium42> robert1971, are you going to add a rainbow sticker?
[22:04] <robert1971> Not the outside. I'm not that mad
[22:04] <jnd> any news about the mission with sstv?
[22:04] <robert1971> :)
[22:10] <natrium42> jnd, jcoxon is the man
[22:10] <natrium42> with the plan
[22:28] <jcoxon> jnd, getting there!
[22:28] <jcoxon> so soon :-D
[22:28] <natrium42> :)
[22:29] <jcoxon> will be pegasus VI - keep an eye on my wiki for announcement
[22:34] <edmoore> shaft on e4!!!
[22:34] <edmoore> the theme tune!
[22:39] Daviey (n=dave@ubuntu/member/daviey) left irc: Read error: 113 (No route to host)
[22:43] <jnd> ok
[22:44] <jnd> do you have trams in britain?
[22:46] <edmoore> not generally, though in isolted cases
[22:54] <jnd> I work in company which makes electronics for tram and trolleybus systems, mainly for the switch control
[22:54] <edmoore> moving to the uk?
[22:55] <jnd> no, I don't know if they do anything for the uk
[22:56] <jnd> but its around the world
[22:56] <jnd> we use 434 and 868MHz transmitters in trams and trolleybuses
[22:56] <jcoxon> jnd, there are quite a few trams in teh UK
[22:56] <jcoxon> less then there used to be
[22:56] <jcoxon> but they are bringing them back
[22:57] <jcoxon> http://www.thetrams.co.uk/tramsinuk.php
[22:57] <jnd> the range is set to only few meters
[22:57] <jnd> thats only place where I work with rf :)
[22:58] <jnd> testing and setting new and servicing used
[22:59] <jnd> I saw you use both those freq in your project
[22:59] <soneil> that's something I'd like to see more of .. they seem to work really well in the various places I've found them around europe
[22:59] <jcoxon> 868 never actualy flew in the air, its only allowed on the ground
[23:00] <edmoore> yeah. I was in Montpelier earlier in the year and the tram system they have there is fantastic
[23:00] <jcoxon> but 434 is good
[23:03] <jnd> we have special "oven" for testing the transmitter/receiver strength
[23:04] <edmoore> that sounds like a really useful tool
[23:04] <jnd> atmel '51 on nearly every board including the encoding and decoding of the signal
[23:06] <jnd> the system works for about ten years
[23:06] <jnd> I wonder how long will those '51 be there :)
[23:07] <jnd> its like x86, old architecture but still new versions appear
[23:07] <jcoxon> http://www.google.com/webhp?hl=xx-pirate
[23:07] <jcoxon> yaaarrgggghhhh
[23:10] <jnd> http://www.google.com/webhp?hl=xx-hacker http://www.google.com/webhp?hl=xx-klingon :)
[23:11] <jcoxon> yeah but its talk like a pirate day
[23:11] <jcoxon> :-D
[23:12] <natrium42> jcoxon, OMG
[23:13] <natrium42> i forgot about it!!!
[23:13] <jnd> 0.04 winks heh
[23:15] <jcoxon> hehe
[23:15] <jnd> natrium42: do you know that you have first image in google on high altitude?
[23:16] <natrium42> o'rly?
[23:16] <natrium42> omg, nice
[23:16] <natrium42> :)
[23:22] <jcoxon> natrium42, hows tricks?
[23:37] <jnd> jcoxon: I see you have no more trolleybuses
[23:39] <jnd> we haven't them in my city but I love the sound of the old ones with the analog control :)
[23:40] <jnd> or maybe its those electromotors
[23:45] <jcoxon> nah i didn't see trolley bus till i visited europe
[23:45] <jcoxon> buses*
[23:46] <Shanuson> there are some in usa too
[23:46] <Shanuson> the most are i russia
[23:46] <Shanuson> in
[23:47] <jcoxon> yeah i used them a lot in russia
[23:49] <Shanuson> did you know, around 1910 there were battery busses in london? they drove 20 miles or so, than they changed the batteries.
[23:50] <jcoxon> that i didn't know
[23:51] <edmoore> yeah, there were electric cars back in the day
[23:51] <Shanuson> but that firm broke, because the boss did want them to succede, he stole a lot of money that way
[23:51] <edmoore> but petrol overtook
[23:51] <Shanuson> did not
[23:52] Laurenceb_ (n=Laurence@host86-144-4-181.range86-144.btcentralplus.com) joined #highaltitude.
[23:52] <edmoore> I saw an 1880 electric car in a museum. I forget what it was called
[23:52] <Laurenceb_> hello
[23:52] <jnd> you probably know skoda as car maker, right?
[23:52] <Laurenceb_> haha
[23:53] <edmoore> uhuh
[23:53] <jnd> but other part of the holding makes trams and trolleybuses :)
[23:54] <Laurenceb_> its all happening here - I was in my front room earlier and there was just a roaring sound approaching then what sounded like a huge explosion followed by screaming
[23:54] <jnd> and locomotives too
[23:54] <Laurenceb_> turned out about 5 boy racers had a pile up at 100mph +
[23:55] <Laurenceb_> theres cars all over the place - half of them are upside down
[23:55] <jcoxon> Laurenceb_, doesn't sound good! everyone okay?
[23:55] <Laurenceb_> yeah only firly minor injuries
[23:56] <jnd> they even made tanks :)
[23:56] <Laurenceb_> very lucky
[23:56] <Laurenceb_> dont know what it is - theres a major accident round my house every weekend atm ;-/
[23:57] <Laurenceb_> just luck I wasnt crossing the road at the time I guess
[23:59] <Laurenceb_> edmoore: do you have a copy of the mlx90609 eval board datasheet?
