[12:01] <juxta> do you live a long way from where you launch rjharrison?
[12:02] <rjharrison> Yep
[12:02] <rjharrison> About 2.5 hr drive
[12:03] <rjharrison> Each way
[12:03] <rjharrison> so 5 hrs
[12:08] <Laurenceb> thats fast
[12:08] <Laurenceb> for leeds/cambridge
[12:09] <juxta> ah, that is a bit of a drive
[12:13] <juxta> I'm just macking around with yagi designs at the moment - I built a couple over the weekend using some yagi design apps, I'm a little confused about impedence though
[12:22] <rjharrison> juxta arn't we all
[12:22] <rjharrison> Rocketboy is your man for this
[12:24] <juxta> hehe
[12:24] <juxta> I made up nice 1.3m yagi rjharrison
[12:25] <juxta> seems to work well - but I also made up a really quick and dirty one using some old coathangers and wood, and it's brilliant considering the effort I put in
[12:25] <SpeedEvil> :)
[12:37] Action: Laurenceb seems to have doppler shift fitting working
[12:37] <Laurenceb> got the error down to about 8m/s
[12:38] <Laurenceb> interestingly most of it is due to the drag
[12:38] <SpeedEvil> Solved the error with multiple bins for cross-track error?
[12:38] <Laurenceb> yes
[12:38] <Laurenceb> and correlating the position error with the velocity error
[12:38] <Laurenceb> - in the bin design
[12:39] <SpeedEvil> you don't get false positives?
[12:39] <Laurenceb> also made some tweaks to the constants used for tuning the noise in the random walk
[12:39] <Laurenceb> yeah its hard to avoid false positives
[12:39] <Laurenceb> to speed it up it chucks out stuff that doesnt converge
[12:39] <SpeedEvil> I suppose a lot will depend if your noise model isn't accurate?
[12:39] <Laurenceb> but sometimes it starts to converge in other bins
[12:40] <Laurenceb> probably best to take just the best converging bin
[12:40] <SpeedEvil> Oh - did you see the cheaper gyros that are out?
[12:40] <Laurenceb> where?
[12:41] <SpeedEvil> http://search.digikey.com/scripts/DkSearch/dksus.dll?Detail&name=497-8960-1-ND - other rates are available
[12:41] <Laurenceb> - theres about 4m/s error due to residual drag above 80km, 2m/s due to noise on the frequency tracking (I added this to the sim) and the remainder due to it not converging well
[12:42] <Laurenceb> thats actually affording
[12:42] <Laurenceb> bandwidth and operating voltage is nice
[12:43] Action: Laurenceb has been learning to use gEDA
[12:44] <Laurenceb> the help files are very good
[12:45] <SpeedEvil> yeah - it's also at the 'knee' price - where it becomes possibly cheap enough for phone makers to integrate it in large numbers.
[12:45] <SpeedEvil> Which drives up the colume, and drops the price for the rest of us.
[12:45] <SpeedEvil> Whcih is nice.
[12:47] <Laurenceb> yeah
[12:47] <Laurenceb> twice the noise denisty of the mlx90609
[12:47] <SpeedEvil> Are you looking at the comparable rate parts though?
[12:47] <Laurenceb> and temperature stability is about half as good
[12:47] <Laurenceb> yes
[12:48] <Laurenceb> but mlx90609 is 75Hz bandwidth and way more expensive
[12:48] <SpeedEvil> And bugger. (bank charges)
[12:49] <Laurenceb> but it has inbuilt adc, temp sensor, spi controlled self testing and debug ect
[12:51] <Laurenceb> but most micros have ADC so its of limited value
[12:51] <SpeedEvil> And some even temp sensors
[12:53] <Laurenceb> how open is the iphone?
[12:53] <Laurenceb> I mean if you jailbreak it
[12:53] <Laurenceb> so you can run your own code... I'm wondering about the accels and magno
[12:54] <SpeedEvil> It's quite open AIUI.
[12:54] <SpeedEvil> I wish the n900 had I2C breakout.
[12:54] <SpeedEvil> And a spare 1cc or so in the case
[12:55] <Laurenceb> yeah I dont know the first thing about it from a sw point of view
[12:55] <Laurenceb> - how low level you can get with the device access
[12:55] <Laurenceb> but if they added gyros it would be a useful platform if its sufficiently hackable
[12:56] <SpeedEvil> I've not looked at it from the POV of not really being interested in hardware that needs to be jailbroken
[12:56] junderwood (n=chatzill@adsl.jcu.me.uk) joined #highaltitude.
[12:56] <SpeedEvil> magno+accel is quite adequate though
[12:56] <SpeedEvil> for 'normal' uses
[12:57] <Laurenceb> yeah - unless they want to get into crazy high performance indoor GPS/IMU stuff
[12:57] <SpeedEvil> Gyro would be very interesting - with pedometer from the accels.
[12:58] <SpeedEvil> Could almost do indoor nav sanely
[12:58] <Laurenceb> but as far as I can tell that arent trying anything like that
[12:59] <SpeedEvil> yes.
[13:00] <Laurenceb> *they
[13:01] <Laurenceb> they do have the capability to combine IMU/GPS and network data
[13:02] <Laurenceb> AIUI atm they just do standard assisted gps
[13:02] <Laurenceb> rather than some really neat "data fusion" navigation techniques
[13:30] <Laurenceb> http://www.examiner.com/x-25061-Climate-Change-Examiner~y2009m11d20-ClimateGate--Climate-centers-server-hacked-revealing-documents-and-emails
[13:30] <Laurenceb> ^ interesting
[13:43] <SpeedEvil> Yes.
[13:43] <SpeedEvil> I come at it from a slightly different angle.
[13:43] <SpeedEvil> Namely that for balance of trade reasons - especially as china rises - we _have_ to go for a massive nuclear program, and energy efficiency program now - or fuel poverty will cripple the nation in the coming decades.
[13:44] <SpeedEvil> This has the side-effect of reducing CO2 of course
[14:00] <Laurenceb> yeah
[14:00] <Laurenceb> Im not a global warming sceptic but theres no doubt they were screwing about with the data
[14:02] <SpeedEvil> I'm unsure how much that's been cherry picked.
[14:02] <SpeedEvil> If for example they are boosting the temps for good reasons.
[14:02] <Laurenceb> yeah
[14:03] <Laurenceb> I know the climate modelling guys at oxford and they have a much better attitude
[14:04] <SpeedEvil> Problem is that if a small portion of the data - and a segment you believe to be insignificant but will be spun as 'proof' is you believe in error...
[14:05] <Laurenceb> well its the attitude of the team as much as anything - the guys at oxford were more interested in general modelling, not global warming
[14:06] <Laurenceb> and tried to steer clear of global warming controversy
[14:07] <Laurenceb> whilst at the same time the work was useful for modelling global warming, but they werent working to prove/disprove warming
[14:08] <Laurenceb> sounds like CRU got too drawn into politics
[14:09] <SpeedEvil> hell of a hard not to if that's where your funding is coming from.
[14:10] <Laurenceb> yeah
[14:13] <SpeedEvil> http://ledgrow.eu/ - interesting.
[14:13] <SpeedEvil> (from a general plant POV)
[14:15] <Laurenceb> lol
[14:15] <Laurenceb> "Amount of dry herb"
[14:15] Action: SpeedEvil doesn't indulge in the herb.
[14:15] <Laurenceb> herb yeah sure just some "herb"
[14:16] <Laurenceb> man I'm so high right now I'm going to... buy more leds
[14:16] <Laurenceb> wait that doesnt work
[14:16] <SpeedEvil> Less fattening than smarties.
[14:16] <SpeedEvil> Plus, the pretty colours may be especially attractive.
[14:17] <Laurenceb> my neightbours were growing it all through the house
[14:18] <Laurenceb> they got busted when they sold it to undercover police
[14:18] <SpeedEvil> oops.
[14:19] <Laurenceb> they managed to claim it wasnt them
[14:19] <Laurenceb> as it was a friend who was organising the operation and actually went to do the sale
[14:19] <Laurenceb> or something like that
[14:20] <SpeedEvil> I see.
[14:20] <SpeedEvil> hence a cheap GPS guided thing capable of delivering a few ounces as a throwaway. :)
[14:20] <Laurenceb> the first thing I knew there were police everywhere and plants being thrown out of the windows, it was pretty weird

[15:43] <rjharrison> Hy RocketBoy
[15:43] <rjharrison> Goo point on the height of the poles
[15:43] <rjharrison> I'm assurred that they can be operarated vertically by one person using a counter weight
[15:43] <RocketBoy> It would be good to ask them
[15:44] <rjharrison> Had a long chat and I have placed the order
[15:44] <RocketBoy> Ah - Ok well as long as they have it covered
[15:44] <rjharrison> Hopefully will give them some use
[15:44] <rjharrison> Sort of catch 22
[15:44] <RocketBoy> I like the counter weight system
[15:44] <rjharrison> Would quite like not to have to use them
[15:45] <rjharrison> Yep that is a good idea
[15:45] <RocketBoy> yeah - you won't really know until its been used for real
[15:45] <RocketBoy> well I thinks its likly that we will
[15:45] <RocketBoy> we have had 3 land in trees to my knowledge
[15:46] <RocketBoy> maybe more
[15:47] <RocketBoy> circa 1 in 20 me thinks
[15:48] <RocketBoy> (one of the 3 was laurenceb's rogello thing
[15:48] <RocketBoy> - so if it was flying horizontally then it stood more chance of hitting a tree)
[15:48] <Laurenceb> that was flying close to horizontal, so more likely to hit trees
[15:48] <Laurenceb> yeah
[15:49] <Laurenceb> it was coming down in a radius 100m or so spiral at an angle of about 15 degrees to horizontal
[15:51] <SpeedEvil> Tree finding algorithm.
[15:51] <RocketBoy> anyone good with ubuntu?
[15:51] <Randomskk> a little, what's up?
[15:52] <RocketBoy> my VDU is 1280 x 768 - but the highest res on this ubuntu is 1152 x 768 - so its fuzzy
[15:52] <Laurenceb> SpeeEvil: possible with a optical mouse sensor
[15:52] <Randomskk> so system/preferences/display doesn't list the resolution it should have?
[15:53] <Randomskk> ubuntu 9.10?
[15:53] <RocketBoy> the graphics card is capable of 1280 x 768 as it was working ok under windows
[15:53] <RocketBoy> yeah 9.10
[15:53] <RocketBoy> yeah - 1152 x 768 is the highest in the list
[15:53] <Randomskk> https://wiki.ubuntu.com/X/Config/Resolution#Adding%20undetected%20resolutions can explain it better than me
[15:54] <SpeedEvil> Laurenceb: yeah - I wish some of the nicer sensors were avaialble.
[15:54] <RocketBoy> ok ta
[15:54] <SpeedEvil> The ones that can report centroids of brightest lights forex
[15:55] <Randomskk> RocketBoy: scroll down as well, someone else reports a similar issue and has another potential fix
[15:55] <Laurenceb> you can get a lot of info by looking at the position output and data quality outputs most sensors give
[15:55] <Laurenceb> problem is you then have to steer
[15:56] <SpeedEvil> yeah
[15:56] <Laurenceb> better to have a releasable chute
[15:56] <Laurenceb> have a cutdown that fires after landing
[15:56] <SpeedEvil> you mean for a rollago?
[15:57] <Laurenceb> no for unguided
[15:57] <SpeedEvil> ah
[15:57] <SpeedEvil> I can imagine something with a ping-pong ball on the bootom, that when struck released the chute
[15:58] <Laurenceb> jst release the chute no matter what
[15:58] <Laurenceb> when you have 8 consecutive seconds of ~0 vertical velocity or something
[15:58] <Laurenceb> - thats how my landing detection on the rogallo works

[16:19] Action: Laurenceb is looking for heatsinks for that 100W led
[16:19] <Randomskk> 100W!
[16:20] <russss> 100W?!
[16:21] <SpeedEvil> 100W LEDs are generally not brighter than 20W of the best LEDs
[16:22] <SpeedEvil> Carefully evaluate power consumption and initial price in both cases.
[16:22] <Laurenceb> http://cgi.ebay.co.uk/HIGH-POWER-100W-WARM-WHITE-LED-7000LM-110Deg-32-36V_W0QQitemZ320442425146QQcmdZViewItemQQptZLH_DefaultDomain_0?hash=item4a9bdb5f3a
[16:22] <Laurenceb> about 92% of the performance of CFL
[16:23] <SpeedEvil> that's not too bad.
[16:23] <SpeedEvil> ~50% of the best.
[16:23] <SpeedEvil> the best linear tubes are ~100lm/W
[16:23] <Laurenceb> so 65 Watt
[16:23] <Laurenceb> as opposed to 115Watt for that
[16:24] <Laurenceb> 57% or 92% of CFL
[16:24] <SpeedEvil> It beats CFLs - which hit 60lm/W typically
[16:25] <Laurenceb> not the descent CFLs
[16:25] <SpeedEvil> possibly.
[16:25] <Laurenceb> I was looking at some of the Osram specs
[16:25] <SpeedEvil> I've been buying them at 49p/6 recently :)
[16:25] <Laurenceb> getting a 100W heatsink is hard
[16:25] <Laurenceb> nice
[16:25] <SpeedEvil> Not really.
[16:25] <SpeedEvil> CPU
[16:25] <Laurenceb> are they subsidised?
[16:25] <Laurenceb> yeah but fanless
[16:25] <SpeedEvil> I would assume so at 8p each.
[16:25] <Laurenceb> ok
[16:26] <Laurenceb> they had stopped subsidising them
[16:26] <Laurenceb> maybe different in scotland
[16:26] <SpeedEvil> My garage has sprouted a ridiculous number as lighting.
[16:26] <SpeedEvil> ~40
[16:26] <Laurenceb> heh
[16:26] <SpeedEvil> Solder them onto a length of 3A cable.
[16:26] Action: Laurenceb has a 1Kw halogen spotlight
[16:27] <Laurenceb> fitted with a UV bulb....
[16:27] <SpeedEvil> yeah - the above is nice as it's an overall light,
[16:27] <SpeedEvil> And painting the ceiling white in addition has really helped
[16:27] <SpeedEvil> limewash++
[16:27] <Laurenceb> it makes a huge difference
[16:28] <Laurenceb> the problem with cpu heatsinks is lack of specs
[16:28] <Laurenceb> http://www.coolinnovations.com/?gclid=COWh29_Ipp4CFYmY2AodsUiblA
[16:30] <Laurenceb> need <0.5C/Watt convective
[16:30] <Laurenceb> and small enough to fit into my ceiling
[16:31] <Laurenceb> http://imagebin.org/72946 has to fit between the beams
[16:34] <SpeedEvil> That's a moderately large light.
[16:34] <SpeedEvil> Why one, not several?
[16:35] <SpeedEvil> A while back when I was looking at sweet spots for price/performance, I came out to ~3W or so multiple spots.
[16:35] <SpeedEvil> I don't think it's moved much from that.
[16:35] <Laurenceb> its already wired for just a few
[16:36] <SpeedEvil> 3W isn't too bad to dissipate with a small passive sink, and it's a usefull amount of light - ~300lm - 20W or so halogen equiv.
[16:36] <SpeedEvil> ah
[16:36] <Laurenceb> actually I'll leave the bayonet fittings in that room
[16:36] <Laurenceb> and stick it in the bining room
[16:36] <Laurenceb> using three or so 50W
[16:36] <Laurenceb> problem is theres not much vertical clearance there
[16:36] <Laurenceb> maybe 80mm
[16:39] <Laurenceb> its a pain to run cables to too many points in the ceiling as you have to drill through the beams
[16:39] <Laurenceb> and that weakens them

[17:26] <Laurenceb> also needs a power supply
[17:27] <Laurenceb> kind of expensive :-/
[17:28] <SpeedEvil> what sort of voltage?
[17:30] <Laurenceb> 33V
[17:30] <SpeedEvil> How many of these?
[17:30] <Laurenceb> two
[17:31] <SpeedEvil> 66V - hmm
[17:32] <Laurenceb> no they are in seperate places
[17:32] <Laurenceb> you cant run the whole thing with 66V
[17:32] <SpeedEvil> Sure you can
[17:32] <SpeedEvil> series
[17:32] <SpeedEvil> oh
[17:32] <SpeedEvil> you mean you might not want them both on
[17:35] <Laurenceb> they are on the lighting circuit
[17:36] <Laurenceb> there are beams and whatnot between them so its not exactly easy to do it any other way than two power supplies

[17:42] <Laurenceb> other problem is they down last that long
[17:42] <Laurenceb> 4 years maybe
[17:43] <SpeedEvil> Where are you getting 4 years from?
[17:44] <SpeedEvil> 100W as a point source seems very bright.
[17:44] <Laurenceb> that pdf
[17:44] <SpeedEvil> oh
[17:45] <Laurenceb> they last longer that CFL but not as well as tubes
[17:48] <Laurenceb> I dont think its practical ATM :-/
[17:49] <Laurenceb> if its this much hassle to assemble you want it to be fit and forget
[17:49] <SpeedEvil> Yeah.
[17:49] <SpeedEvil> Hence why I was looking at 3W
[17:49] <SpeedEvil> The heatsinks are a _lot_ simpler.

[19:26] <Laurenceb> depends who you want to sell it to I guess

[19:29] <SpeedEvil> especially if you go the 'easy' route and simply have exteranl mixers
[19:30] <Laurenceb> AD integrated VCO/PLL ICs looked good origionally
[19:30] <Laurenceb> but you cant get very good frequency range
[19:31] <Laurenceb> for HAM use covering the region around 10MHz would be good
[19:32] <Laurenceb> 1.8MHz to 28MHz would be good
[19:34] <Laurenceb> http://www.analog.com/en/rfif-components/pll-synthesizersvcos/adf4360-9/products/product.html provides good frequency range, but only if you use the digital output
[19:34] <Laurenceb> maybe DDC becomes practical at those frequencies

[20:24] <DanielRichman> sbasuita, range test?
[20:24] <sbasuita> DanielRichman, definitely
[20:24] <rjharrison_> Cool
[20:24] <rjharrison_> Get it up high some where on a hill
[20:25] <rjharrison_> and then drive away with the radio tuned
[20:25] <sbasuita> DanielRichman, we'll put it sideways on top of a tall parking lot or something and see how far we can hear it from
[20:25] <DanielRichman> i'll get out an Ordanance survey map sometime this weekend and see where we could test from/to
