[06:50] <eroomde> Upu: that new curiosity lsnding video is really good isnt it
[06:50] <UpuWork> yes very
[06:50] <UpuWork> movie levels of excitement
[06:50] <eroomde> just watched it again over toast now that the crazy first half of the week (60 hrs work so far...) is over
[06:50] <UpuWork> we need to get up early don't we
[06:51] <UpuWork> link it again pls I want to watch it :)
[06:51] <UpuWork> http://upload.wikimedia.org/wikipedia/commons/4/46/New_Horizons_1.jpg
[06:51] <UpuWork> just looking at that :)
[06:51] <eroomde> yes ill be staing up
[06:51] <eroomde> i want to go and see tom rivellini in sept but i might not ask before i knoe the outcome :)
[06:52] <eroomde> http://www.theregister.co.uk/2012/06/27/nasa_curiosity_countdown/
[06:52] <eroomde> has video embedded

[06:52] <eroomde> yeah its just so nervracking but awesome doing mechatronicy things
[06:52] <UpuWork> bit of Immediate Music score in the background
[06:52] <eroomde> i like have to use electronics to sequence macheanical things at really accurate times
[06:53] <UpuWork> the whole thing is just concentrated awesome
[06:53] <eroomde> i like the complex ballet of interacting subsystems
[06:53] <UpuWork> I really hope it works
[06:53] <eroomde> yeah... its gonna be a tough time if it does
[06:53] <eroomde> t
[06:53] <UpuWork> I love the little rockets keeping it pointing right as it comes in to the upper atmosphere
[06:53] <eroomde> i just like adam seltzingers bit at the beginning
[06:54] <eroomde> sdmiting the whole things just looks bonkers
[06:54] <UpuWork> lol
[06:54] <UpuWork> 200 mph under a parachute
[06:54] <eroomde> yeah its cool, theyre trying to do lift to drag on the entry on this one
[06:54] <eroomde> so surfing it on its own shockwave
[06:54] <eroomde> to steer it a bit to a tighter landing spot
[06:55] <UpuWork> I hope it works or those Martins are going to be pissed as we irradiate a small section of their surface
[06:56] <eroomde> at least it helps with the biological contaminents
[06:56] <UpuWork> yep
[06:56] <eroomde> but yeah, as you say, seriously concentrated awesome
[06:56] <eroomde> or 'boss as fuck' as your hydrogen poster says
[06:56] <eroomde> thats become a bit overused at work now since that
[06:57] <eroomde> so we had all sorts of shit yesterday
[06:57] <eroomde> getting the same engine to light vertically
[06:57] <eroomde> theres an old saying that it's one thing to fire a rocket, quite another to light it
[06:57] <eroomde> and its true, blimey
[06:58] <daveake> That's an incredible landing sequence
[06:58] <daveake> Amazing if they pull it off
[06:59] <fsphil> the only flaw is nobody is there to see it
[06:59] <eroomde> oh god dont
[06:59] <fsphil> great video, just watched it for the first time
[06:59] <eroomde> try persuading scinetists of the value of 300g spent on an upwarding facing camera on the rover to film edl
[06:59] <eroomde> just for the engineering data
[07:00] <eroomde> it's a lost cause
[07:01] <UpuWork> back sorry just been showing our sales guy the landing
[07:01] <UpuWork> he just laughed
[07:01] <UpuWork> "and they seem like such clever people as well"
[07:02] <UpuWork> that camera will be the best 300g anyone ever spent
[07:02] <eroomde> i would say so
[07:02] <eroomde> but last time i said this you pointed out that i was obsessed
[07:03] <eroomde> but yeah i mean thats why i was so keen to do the testing at our scale. we just have so little data sbout how the chutes perform
[07:03] <eroomde> the accelerometer data from phonix looks like its chute wasnt working properly
[07:03] <eroomde> so does that unbeleivable stunning photo
[07:03] <eroomde> looks like the chute isnt work
[07:04] <eroomde> oh did you see the photo of phoenix descending which was caught by a sat in mars orbit?
[07:04] <eroomde> its just breathtaking
[07:04] <UpuWork> no ?
[07:04] <UpuWork> linky
[07:04] <fsphil> is my fav image
[07:04] <fsphil> from space ever
[07:04] <daveake> oh yeah, saw that
[07:05] <fsphil> http://www.nasa.gov/mission_pages/phoenix/images/press/PSP_008579_9020_descent.html
[07:05] <UpuWork> wow
[07:06] <eroomde> but look, chute doesnt look properly deployed

[07:06] <eroomde> suspect it might be jellyfishing
[07:06] <daveake> Nearly as good as AVA from CLOUD :)
[07:06] <eroomde> they were also surprised by mer chutes
[07:07] <eroomde> they just had plenty of margin in the retrorockets to absorb chute performance errors
[07:07] <eroomde> but its still not cool
[07:07] <UpuWork> the Phoenix one worked ok though didn't it
[07:07] <UpuWork> that was the small Sorjourner rover ?
[07:07] <eroomde> no, that was pathfinder
[07:07] <eroomde> with the small rover
[07:07] <UpuWork> Which one was the Phoenix one ?
[07:07] <eroomde> they certainly sisnt have the tech to take that photo in 1997
[07:08] <eroomde> phoenix was a stantionary lander at the poles
[07:08] <UpuWork> ah ok
[07:08] <UpuWork> and Spirit and Opportunity are the larger rovers that they are sending Curiosity to dig out
[07:08] <eroomde> correct
[07:08] <eroomde> some of the most successful things ever
[07:08] <UpuWork> http://www.nasa.gov/images/content/230838main_PSP_008579_9020_descent.jpg where is the high high resolution of that
[07:09] <eroomde> UpuWork: so on youtube
[07:09] <eroomde> theres a talk on the computer history museaum channel
[07:09] <eroomde> by pete theiseinger (sp?) the mer pm
[07:10] <eroomde> which is purest techy talk about developing spirit and opportunity, for about 2hrs
[07:10] <eroomde> its a fantastic talk
[07:10] <eroomde> lots more detail about the challenges of landing
[07:10] <UpuWork> http://phoenix.lpl.arizona.edu/05_25_10_pr.php its broken
[07:10] <number10> daveake: cuddykid is not launching this weekend - he mentioned it yesterday but you were no on the chan
[07:10] <UpuWork> I'll try find that eroomde
[07:10] <daveake> Ah, thanks #10kV
[07:10] <UpuWork> heh
[07:11] <number10> zzzt :(
[07:11] <number10> but he was asking if you were around in the week daveake
[07:11] <UpuWork> if anyones interested fsphil and I got DominoEX out of an NTX2 last night using a single PWM Line
[07:12] <number10> thats nice UpuWork
[07:12] <UpuWork> in fact it easily got 1200 baud RTTY using PWM with no resistors
[07:12] <number10> would be good to have some variation in HAB transmissions
[07:14] <UpuWork> its very sensitive to shift
[07:14] <UpuWork> 18 tones over 355hz
[07:14] <eroomde> yeah u need temp comp or some kind of comp with domino ex
[07:14] <UpuWork> Bill Browns managed it
[07:14] <UpuWork> not sure how
[07:15] G8KNN-Jon (~Jon@cpc1-cmbg10-0-0-cust144.5-4.cable.virginmedia.com) joined #highaltitude.
[07:15] <daveake> UpuWork I tried 1200 with 425 shift from the pi, and it was OK but not 100%. Presoomably a wider shift is the trick?
[07:15] <UpuWork> I think I pushed the shift up a little but nothing massive
[07:15] <UpuWork> it was fine
[07:15] <daveake> ok
[07:15] <eroomde> we did dominoex on the badger1 flight computer. the dac resolution was a bit low tho for it to be reliable
[07:16] <UpuWork> no DAC on this eroomde
[07:16] <eroomde> yes i read
[07:16] <UpuWork> just PWM with about 350k Resistor in line
[07:16] <eroomde> tho it is a dac of course :p
[07:16] <UpuWork> well yes I suppose so
[07:16] <daveake> D in A out. Sounds like a DAC to me :p
[07:24] <eroomde> well itll be cool to see if fly
[07:25] <eroomde> did you do the fec version?
[07:25] <UpuWork> not yet
[07:25] <UpuWork> just playing last night
[07:25] <UpuWork> https://dl.dropbox.com/u/63720513/Images/HAB/pwmrtty.png
[07:26] <UpuWork> software adjustable shift
[07:28] <eroomde> stick an rc filter inline and see if it makes a difference to the size of the lobes
[07:28] <fsphil> I believe all of the MFSK modes are going to be seriously sensitive to the variable shift
[07:28] <UpuWork> yeah I'll need to do some maths
[07:29] <UpuWork> I like big lobes and I cannot lie, my other brothers do not lie..
[07:29] <gonzo_> the doppler/G shift is going to be the killer there
[07:30] <UpuWork> baby got bandwidth
[07:30] <fsphil> it's suprisingly tolerent of drift
[07:30] <UpuWork> yeah it drifted out and still decoded
[07:30] <fsphil> needs manual tuning though
[07:30] <UpuWork> what resistor value did you end up with ?
[07:31] <fsphil> I'm not sure actually, there's two in there
[07:31] <eroomde> yeah dominoex's killer feature is that data is incoding in the jumps between symbol frequencies
[07:31] <fsphil> will check when I get home
[07:31] <eroomde> not the absolute symbol frequencies themselves
[07:31] <fsphil> I think we need a mode with 4 tones rather than 18
[07:31] <gonzo_> afc could probably follow mfsk, but if you get qsb then the afc could get confused what to lock to
[07:32] <UpuWork> custom mode fsphil ? :)
[07:32] <UpuWork> something with a shift that the RFM22B could do
[07:33] <fsphil> or something with variable shift like rtty
[07:33] <fsphil> not an mfsk mode
[07:33] <fsphil> but fsk at least
[07:34] <fsphil> and no start/stop bits
[07:36] <fsphil> and convolution coding
[07:36] <fsphil> and a pony
[07:36] <eroomde> just some fec would make the world of difference to rtty
[07:36] <eroomde> its such low hanging fruit
[07:45] <fsphil> mixing fec and rtty isn't ideal
[07:45] <fsphil> but yea, better than nothing

[09:23] <SpeedEvil> ssh -D
[09:23] <eroomde> could someone quickly google for me what the arguement for xargs is that puts c-string escape characters into the output?
[09:23] <SpeedEvil> and then tell ...
[09:23] <SpeedEvil> ah
[09:23] <SpeedEvil> c-string?

[09:23] <SpeedEvil> you mean null?

[09:24] <russss> eroomde: ^
[09:24] <SpeedEvil> what do you want the output to look like?
[09:24] <SpeedEvil> and -0 splits the input to xargs on 0's
[09:24] <russss> actually, -0 accepts null-terminated *inputs*
[09:24] <SpeedEvil> not newlines

[09:47] <eroomde> not sure it was particularly to do with atmospherics but tey do often make a difference
[09:57] <kokey> my girlfriend, when she was still living in spain, lived in an apartment that had the bills included, and the boiler's release valve was leaking
[09:58] <kokey> so it kept on letting hot water out on the overflow at the back, and it kept boiling
[09:58] <kokey> the flat was so hot and humid, nothing could burn in it
[09:58] <eroomde> mmm
[09:58] <eroomde> i think that probably didn;t help us
[09:58] <kokey> it had split unit aircon, which I really could have used, but she told me that she didn't want to use it because of the cost
[09:59] <kokey> but she didn't tell me that the bills were included
[09:59] <eroomde> but i think mainly the problem was that in vertical mode, the simple igniter we were using for horizontal (quickmatch etc) falls to the bottom on the chamber which is graphite
[09:59] <kokey> I was quite annoyed when I worked that out only a few months later
[09:59] <eroomde> but when horizontal it falls to the side of the chamber wall which is a phenolic liner
[09:59] <eroomde> and liner chars a bit and you get a hybrid-type decomoposition and byrning when we let the n2o in
[10:00] <eroomde> which cna get get the n20 and ipa going properly when you let some ipa into the chamber and thorrle up
[10:00] <eroomde> in this case the ignitor products fall back towards the throat and just get blown out (kept happening) when the n20 pressure build in the chmaber
[10:00] <eroomde> with a pop
[10:00] <eroomde> we need quite a serious rethink
[10:00] <kokey> I wonder how often that happens with rocket development
[10:01] <kokey> since burn tests are usually sideways
[10:01] <eroomde> there is a saying that firing a rocket is one thing, lighting it is quite another
[10:01] <eroomde> it's not wrong
[10:01] <eroomde> well for the 'proper' rockets we do we have a nice hydrogen oxygen preburner jet
[10:01] <eroomde> that Just Works (tm)
[10:02] <eroomde> but this is a much smaller rocket and is going to fly and is an internal after-hours project for us
[10:02] <eroomde> just to see if we can do the hoving lunar-lander style rockets
[10:02] <eroomde> hovering*
[10:02] <kokey> would be nice if there was a simple cheap solution for that
[10:02] <kokey> oh, nice, small lunar landers
[10:02] <eroomde> and integrating 2 new gases (hydrogen and oxygen) and a complete pre-burner in what is already a very crowded injector plate on a small motor is going to be a trick
[10:02] <SpeedEvil> http://en.wikipedia.org/wiki/NanoFoil
[10:03] <SpeedEvil> looks like an excellent ignitor for solids
[10:03] <eroomde> mmm
[10:04] <eroomde> well if we didn;t mind liquid-phase igniters we'd just use thermite
[10:04] <SpeedEvil> http://buy.solder.com/NanoFoil-Bundle-Kit-40-Microns-x-5-Inch-Squares/P1069_1019/
[10:04] <eroomde> that'd dump enough thermal energy into the chamber to get the party going
[10:04] <eroomde> we used thermite for our big 2-stage scotland rocket in may
[10:04] <SpeedEvil> It'd be nice if it was a bit cheaper though
[10:04] <eroomde> but for this we're thinking we might aswell solve the problem with a relightable
[10:05] <eroomde> mid-flight relights would prove a point
[10:05] <SpeedEvil> That is handy, if you can do it
[10:05] <eroomde> it just elps for testing too
[10:05] <SpeedEvil> I was pondering a trinary injector
[10:05] <eroomde> makes the turnaround time faster between tests
[10:05] <SpeedEvil> for my experimental thingy
[10:05] <SpeedEvil> H2O2/kerosene
[10:06] <SpeedEvil> with a little injector that fills the last bit of the kerosene line with a permanganate rich solution of some form
[10:06] <eroomde> for example the next thing for it will be to close the loop on the throttle valves by putting injector pressors into the control system
[10:06] <eroomde> currently we just log them and do open-loop on the servos
[10:06] <eroomde> but the servo valves are pretty slow which is a big pole in a nasty place
[10:07] <eroomde> so it will take quite a lot of testing and analysis to design it and tune it
[10:07] <SpeedEvil> Large injectors for diesel engines have been used IIRC
[10:07] <eroomde> yeah that's quite a common thing to do
[10:07] <eroomde> some third thing to kick it off
[10:07] <eroomde> usualy called a 'hypergolic slug' though i guess it's not quite in this case
[10:08] <eroomde> but again that's big faff to reset between tests
[10:08] <SpeedEvil> Indeed.
[10:08] <eroomde> it's actually very non-trivial to clean down the injectors then load a specific amount of a third substance into a portion of one of the injectors
[10:09] G8KNN-Jon (~Jon@cpc1-cmbg10-0-0-cust144.5-4.cable.virginmedia.com) left irc: Ping timeout: 246 seconds
[10:09] <SpeedEvil> I know - I was basically relying on a sryinge to pump a known quantity into the pipework, with teh valves off
[10:09] <SpeedEvil> - at least on paper
[10:09] <eroomde> it's always ground handling and human interface issues that people ignore in the design 'because this is aerospace' and infact it's about the most important thing, i think
[10:10] <SpeedEvil> If you are deeply throttling the engines in this sort of app, you really, really want to be able to relight them 'properly' though.
[10:10] <eroomde> indeed
[10:10] <eroomde> we've got 5:1 throttling on this engine too
[10:10] <eroomde> on the horizontal tests
[10:10] <eroomde> which is v deep
[10:10] <SpeedEvil> And actually turning them off for periods may be considerably more efficient in some cases.
[10:10] <SpeedEvil> Nice!
[10:10] <eroomde> so yeah, we do need to find a way
[10:11] <SpeedEvil> Air lighting is of course handy for reuse in multistage :)
[10:12] <eroomde> here you go: http://i.imgur.com/diIUF.png
[10:12] <eroomde> so that's thrust vs the commanded position to the n20 and ipa servos
[10:12] <cuddykid> and the thunder starts again!
[10:12] <eroomde> so you can see the engine is reasonably controllable and behaves quite nicely
[10:12] <eroomde> for something made of leftovers and hobby servos anyway :)
[10:13] <SpeedEvil> Are uyou suffering from the propellant tanks depressurising too?
[10:13] <eroomde> but you can also obviously see the effect of tank pressure reducing
[10:13] <SpeedEvil> :)
[10:13] <eroomde> yes indeed - good spot :)
[10:13] <eroomde> hence the desire to close the loop on the throttle servos by putting injector pressures into the controller
[10:14] <SpeedEvil> How much are you ablating?
[10:14] <SpeedEvil> - what life
[10:14] <eroomde> about 90s
[10:14] <eroomde> we estimate
[10:14] <eroomde> at full throttle
[10:14] <SpeedEvil> Not bad at all
[10:14] <eroomde> but the next version of this engine is regen anyway
[10:14] <cuddykid> daveake: are you free any time in the latter part of next week? - I've asked David to see if he can get me permission as winds look better (even though way off)
[10:14] <SpeedEvil> About what you want for a first stage to take you out of the thick atmosphere, and get supersonic for teeny rockets
[10:14] <eroomde> just trying to play whack-a-mole interate on the entire system
[10:14] <eroomde> iterate*
[10:15] <eroomde> SpeedEvil: yes indeed
[10:15] <SpeedEvil> iterate-iterate-boom
[10:15] <eroomde> of indeed for decent microgravity experiments
[10:15] <SpeedEvil> yep
[10:15] <eroomde> there's often an acceleration constraint on the experiments
[10:16] <eroomde> so thse big 30G sounding rockets are no good, even though you'll get a few mins of 0G after burnout
[10:16] <SpeedEvil> A couple of 90s capable stages with the first throttleable can get you quite high indeed.
[10:16] <SpeedEvil> even for teeny rockets.
[10:16] <eroomde> so we're thinking just keep a steady 2G say, all the way out of the atmosphere, with active
[10:17] <SpeedEvil> For small (sub 5 ton GLOW) transonic drag is painful.
[10:17] <SpeedEvil> At least according to modeling I did ages ago.
[10:18] <SpeedEvil> Accellerating hard to mach 0.8, then sustaining till you hit ~20-30km, before accellerating again saves fuel.
[10:18] <SpeedEvil> Even with the added gravity loss.
[10:18] <fsphil> why not launch from a high altitude aircraft. is it a weight thing?
[10:20] <eroomde> SpeedEvil: sounds v sensible
[10:21] <SpeedEvil> You can - almost get down to orbital capable being something you can carry - if you don't try to fight the drag too much. Certainly unfueled.
[10:22] <eroomde> just more faff
[10:22] <SpeedEvil> yeah
[10:22] <SpeedEvil> It's a hell of a lot simpler if your rocket weighs over a thousand tons. :)
[10:22] <eroomde> or if your rocket is also an aircraft :)

[10:30] <eroomde> is this for conf?
[10:30] <jcoxon> yeah
[10:30] <eroomde> hmm
[10:31] <eroomde> this is the nearest we got to lighting the rocket yesterday (sparks are just from igniter building up the chamber pressure)
[10:31] <eroomde> http://i.imgur.com/o7QGK.jpg
[10:34] <SpeedEvil> Is that a gimbal, or a big linear bearing for a strain guage?
[10:34] <SpeedEvil> On the side
[10:34] <eroomde> on the right hand side is a linear actuator
[10:35] <eroomde> the black carbon fibre tube thingamie
[10:35] <SpeedEvil> For any particular reason, or just because it's nice to test multiple things with one rig?
[10:36] <eroomde> yes we're testing gimballing
[10:36] <eroomde> the engine was going to be gimabllling around if it lit
[10:36] <eroomde> that was part of the potted test sequence
[10:36] <eroomde> http://www.flickr.com/photos/69676024@N07/7432603668/in/photostream/
[10:36] <eroomde> they are them ^
[10:36] <eroomde> homemade
[10:36] <SpeedEvil> I assume t:w is bad, as not much weight reduction has been done?
[10:37] <eroomde> oh totally uninterested in t:w for this
[10:37] <eroomde> it's a lunar lander
[10:37] <SpeedEvil> Ah.
[10:37] <SpeedEvil> I see.
[10:37] <eroomde> it just need to be able to go up
[10:37] <eroomde> so it's like 1.3:1 at full thorrtle
[10:37] <eroomde> throttle*
[10:37] <SpeedEvil> :)
[10:38] <eroomde> then regen engine will be quite a lot more powerful though

[11:03] <eroomde> SpeedEvil: to answer you q more thoroughly (sorry got distracted) re: http://i.imgur.com/o7QGK.jpg
[11:03] <eroomde> there is a load cell
[11:04] <eroomde> it's the big ali chink with the hole cut out on the left side of the rig, bolted at once end to the steel test stand (pyramidal structure) and at the other to the rocket bulkhead
[11:04] <SpeedEvil> Oh - that was quite obvious
[11:04] <SpeedEvil> should have noticed that :)
[11:04] <eroomde> then all the other cables coming off are from pressure transducers, doing to our datalogger that is out of shot
[11:05] <eroomde> there there are a few gopros dotted around
[11:05] <SpeedEvil> Looks good. (neglecting the lack of actual thrust)
[11:05] <eroomde> including the danger-gopro on the right
[11:05] <eroomde> they were the film crew's
[11:05] <eroomde> they're f-ing awesome though
[11:05] <eroomde> i want
[11:06] <SpeedEvil> :)
[11:06] <eroomde> also the film crew had this little handheld hdmi monitor that they could use to frame the gopros
[11:06] <SpeedEvil> Is that a ruggedised one?
[11:06] <eroomde> it was awesome!
[11:06] <eroomde> i want one of those too
[11:06] <eroomde> it's in its ruggesdised case yeah
[11:07] <eroomde> was this i think http://www.coollcd.com/lilliput-667gl-7-inch-oncamera-hd-lcd-field-monitor-w-hdmi-component-composite_p734.html?zenid=8164d5e9e15f7f370d6dbab25328ff10
[11:12] <fsphil> hdmi monitor would be cool
[11:12] <eroomde> yeah, really helpful for setting things up correctly
[11:12] <fsphil> did everything go well today?
[11:12] <eroomde> and not having to have a laptop to play back the video from a trial position
[11:13] <eroomde> no we stopped at 10pm yesterday
[11:13] <eroomde> we workd 9am monday to 8pm tuesday solidly, thanks to coffee, and 9am yesterday to 10pm yesterday
[11:13] <eroomde> and yesterday showed that we just need a rethink on ignition
[11:14] <eroomde> so we've told the tv crew to come back in like 2 weeks, which works for them too as they've loads of stuff going on atm anyway
[11:14] <eroomde> and then we can figure out the problems with clearer heads and machine up something proper
[11:15] <eroomde> i think we'll just go for some kind of gas torch going into the engine from the injector plate, with a spark of glow-plug to ignite it
[11:15] <eroomde> spark or glow*
[11:15] <eroomde> that technique works really reliably for big stuff
[11:16] <eroomde> infact i put exactly such a box on the test rig for the jet engine that is running skylon tests, because the old rolls royce viper engine ignition system was just poo
[11:16] <eroomde> http://www.bbc.co.uk/news/science-environment-17864782
[11:16] <eroomde> it's the grey box sticking out of helen's back

[12:08] <kokey> casting a vacuum balloon out of lead should be easy
[12:08] <eroomde> i told you how to do that
[12:08] <eroomde> just have 10kg payloads like we do
[12:09] <fsphil> lol
[12:09] <eroomde> they make light work of a few small branches
[12:10] <SpeedEvil> Or go slightly bigger, and take out entire cars.
[12:10] <eroomde> i think a 10kg lump, if sufficienctly point and without chute, would do that

[12:34] <daveake> Wrong question :)
[12:34] <Laurenceb> holy unanswerable question batman
[12:34] <eroomde> 2 farads though is the answer
[12:34] <Lunar_Lander> XD
[12:34] <eroomde> you might want to get onto steve about his stock of 3kg balloons
[12:34] <Laurenceb> between 2pF and 2F
[12:35] Action: UpuWork pokes Laurenceb
[12:35] <Lunar_Lander> 22 pF are too less my professor said
[12:35] <eroomde> Laurenceb: one of the first rules about being a successful design engineer, which hopefully you'll learn when you become as experienced as me one day, is that it doesn't make sence to specifiy things too tightly
[12:35] <Lunar_Lander> hello UpuWork
[12:35] <UpuWork> hi Lunar_Lander
[12:35] <UpuWork> 100nF
[12:35] <Lunar_Lander> thanks
[12:35] <Lunar_Lander> ceramic right?
[12:35] <Laurenceb> lol
[12:36] <eroomde> Laurenceb: yep ceramic is fine
[12:36] <daveake> 100nF ceramic close to the component
[12:36] <UpuWork> yeah put them as close as you can to the power on the component
[12:36] <eroomde> also have sime bigger smoothing caps by the 3.3V source
[12:37] <eroomde> they can be polarised, eg aluminium electrolytic or tantalum
[12:37] <Lunar_Lander> that I got, I got from the regulator datasheet how to put them up
[12:37] <Lunar_Lander> yea
[12:37] <eroomde> cool
[12:37] <Lunar_Lander> one 100 nF and IIRC a 0.1 uF on the other side
[12:37] <Lunar_Lander> and that one is polarized
[12:37] <daveake> So the elect or tant is for long current demands; the ceramics for the short spikes
[12:37] <fsphil> lights are flickering, lightning must be getting closer
[12:38] <eroomde> it doesn;t have to be polarised by definition, it's just that capactiros of that size almost always are polarised
[12:38] <daveake> Stick a 2F on the mains
[12:38] <eroomde> just the way the chemsistry/phsyics works
[12:38] <daveake> That'll fix it
[12:38] <Lunar_Lander> daveake, xD
[12:38] <Lunar_Lander> true eroomde
[12:39] <eroomde> Laurenceb: did you ever look at the sort of data rate throughput you could get with dma on the cortex m4?
[12:39] <Laurenceb> not yet
[12:39] <Lunar_Lander> but is it true that tantalum capacitor can fail rather spectularly?
[12:39] <eroomde> if so, does 30MBit sound reasonable?
[12:39] <Laurenceb> one of my many jobs to complete
[12:39] <Lunar_Lander> *s
[12:39] <eroomde> oh ok not to worry
[12:39] <Laurenceb> Bit?
[12:39] <Laurenceb> yes certainly id say
[12:39] <daveake> Tants make a unique smell when you kill them
[12:39] <eroomde> Laurenceb: cool
[12:39] <Laurenceb> the dma is improved over F1
[12:40] <eroomde> just wondering about running the 200ksps, 16bit 8ch adc at full pelt
[12:40] <eroomde> for some highly dynamic stuff
[12:40] <Laurenceb> much better memory crossbar
[12:40] <daveake> You'll find out if you get the polarity wrong or exceed the max voltage
[12:40] <eroomde> wear goggles ^
[12:40] <Lunar_Lander> xD
[12:41] <daveake> For tants? IME they just smoke. Electrolytics however ....
[12:41] <Lunar_Lander> yea
[12:41] <Lunar_Lander> they may burst, right?

[13:22] <fsphil> it's the flat end isn't it?
[13:23] <daveake> Hence the term "flat battery" when both ends are flat
[13:23] <eroomde> i guess there's no potential difference between them if they're both flat
[13:24] <number10> I was trying to work out how much voltage could be induced in a tracker from the magnetic field of a over head transmission line
[13:25] <daveake> You could have measured that last time
[13:25] <SpeedEvil> Essentially zero compared with tangling in it, and being directly connected
[13:25] <number10> lol, wasnt near enough and was only 11kv lines
[13:25] <daveake> I prefer 10kV for the comic opportunities
[13:25] <number10> thanks
[13:25] <SpeedEvil> Magnetic field largely cancels.
[13:27] <number10> people a lot more cleverer than me did some fag packet calculations - assume 1000A at 0.1m worked out 0.6mv for a 10sq cm circuit loop

[15:09] <nigelvh> It seems to be frequently the case in IT. People take care of their home computers, so they automatically think that running a network and a pile of servers is just the same.

[15:13] <nigelvh> Then there's a few of them who know they don't do my job, but manage to stumble into interesting problems. One of them managed to crash our fileserver by creating an infinitely recursive copy script that exceeded the windows path length.
[15:14] <fsphil> in my case I learned that a faster cpu doesn't actually make a better server. the machine I built up was actually slower in the end
[15:14] <nigelvh> Another one of them messed up a different server by filling the drive with a few hundred thousand tiny files. There was space left, but the filesystem couldn't keep track of all the files.
[15:14] <Lunar_LanderU> yea
[15:14] <Lunar_LanderU> nigelvh: what do you think of the scan result?
[15:14] <nigelvh> Yeah, the hardware is only one aspect.
[15:15] <nigelvh> I'd say it's fine. Nothing else picked anything up, and the one that did is using the heuristics rather than a real definition, so they're much more prone to false positives.
[15:16] <Lunar_LanderU> yea

[15:22] <UpuWork> they are ok but HP charge lol money for SSD in servers £1200 per drive in some cases

[15:23] <UpuWork> moved to HP and never looked back
[15:23] <nigelvh> Place I'm at now is pretty much all dells. Mostly in a big blade enclosure and running a ton of VMs on them.
[15:24] <kokey> at rackspace when I worked there, most of the servers were white box clones
[15:24] <kokey> but they built them in numbers to could figure out what parts worked, and what parts didn't
[15:24] <kokey> turned out to be asus motherboards, kingston ram, seagate hard drives, intel nics... but this was back in 2004
[15:25] <UpuWork> Rackspace use Dell now at least they did when I saw them putting 2 racks worth of kit in the data center we use
[15:25] <kokey> dell for servers, unless you only run a few, were a pretty bad idea until recently
[15:25] <UpuWork> 96 1U dells
[15:25] <kokey> fortunately dell now makes ranges that compete with the HP servers, where they keep chips the same inside of generations of models

[15:38] <eroomde> this has to go east to west
[15:38] <eroomde> so presumably needs some sort of intelligence to tack
[15:39] <SpeedEvil> Trained dolphin.
[15:39] <eroomde> i reckon a fixed wing sail on a rotating mast, a rudder, and a long ballasted keel that will cause it to self-right
[15:39] <eroomde> then its a software problem
[15:40] <SpeedEvil> yup.
[15:40] <SpeedEvil> Add solar, and _lots_ of sealant, and you're golden.
[15:40] <eroomde> yes indeed
[15:41] <eroomde> ive been wating to play with solar power managemrnt anywa
[15:42] <SpeedEvil> Plus, it's a good cover for other things.
[15:42] <SpeedEvil> 'You mean there was an unauthorised rocket launch, and a new satellite, just after we lost contact with our vehicle?' 'What are the chances of that?'
[15:43] <nick_> I wonder how prototype friendly you could make it.
[15:43] <nick_> Presumably you'd want the ability to do a code update mid transit?
[15:44] <fsphil> that's not allowed (for the microtransat)
[15:44] <fsphil> it's allowed to receive weather data and act on that, but it can't have any remote control at all
[15:44] <jiffe98> so before I do my next launch I'm trying to do distance testing of my rig, I have
[15:45] <nick_> Is that remote control?
[15:45] <jiffe98> a T2-301 transmitter at 5 watts, kenwood tm-d700 receiver and I'm getting about 30 miles line of sight off that but no further
[15:46] <jiffe98> does that sound about right?
[15:46] <jiffe98> 5 watts seems like it should travel farther
[15:46] <eroomde> nick_: i think that would count as remote control
[15:47] <eroomde> but following your prototype logic, instead of entire dinghies and expensive big actuators, i would just try and make it as simple as possible
[15:47] <eroomde> and afford to loose a few and keep trying
[15:47] <eroomde> and wee
[15:47] <nick_> Ah, it's against the rules to transmit software updates :(
[15:47] <eroomde> yes
[15:48] <eroomde> but again, a solid tacking algorithm, good power management and self-righting and i think you might be in with a chance
[15:48] <eroomde> even if its not nearly as fast as the bigger ones
[15:49] <nick_> I wonder if you could outfit a kayak to do it.
[15:49] <nick_> Ah
[15:49] <nick_> The one boat looks pretty small
[15:50] <nick_> 1.4m
[15:51] <nick_> eroomde: there's a boat pond in the park next to where I live.
[15:51] <nick_> They're usually playing with boats that aren't much smaller than that.
[15:51] <eroomde> nice
[15:51] <eroomde> thats the sort of size i was thinking
[15:51] <nick_> (at last for the sailing boats)
[15:51] <eroomde> 1-2m long main hull with outriggers
[15:52] <nick_> I wonder how much route planning information they load it up with.
[15:53] <nigelvh> 10: Follow compas
[15:53] <eroomde> if its unobstructed, just head to a landing spot on the other side
[15:53] <nigelvh> 20: avoid tankers
[15:54] <eroomde> u could do clever things like tell it night to fight tides
[15:54] <eroomde> not
[15:54] <nick_> I don't know if there are better routes across or anything
[15:55] <nigelvh> Well, There are reasonably well mapped surface currents. Finding which ones are useful is another story.
[15:55] <fsphil> the weather data has to come from one of the regular HF weather services, it can't come from yourself
[15:55] <nick_> Or whether you'd do better to hibernate overnight.
[15:56] <eroomde> nah just keep going :)
[15:56] <eroomde> if power budget allows
[15:56] <fsphil> I was going to launch something myself but it turns out I'm rubbish at boat making

[16:01] <fsphil> jonathan (the guy who launched projectcirrus with me a few years ago) suggested a balloon/kite combo
[16:01] <nigelvh> Would you rather lock it during a storm, or let it "float" like a wind vane?
[16:02] <eroomde> locking comes for free if you use worm gears
[16:02] <eroomde> ie you worm can turn the mast pinion but the pinion cannot turn the worm gear
[16:02] <nigelvh> Good point. I like that idea.
[16:02] <fsphil> ahh
[16:03] <eroomde> but it might impact the dynamic response a bit
[16:03] <eroomde> equally, might still be good enou
[16:03] <fsphil> some way to measure the pressure on the sail might be useful
[16:04] <fsphil> and the bit that goes underwater
[16:04] <eroomde> yeah indeed
[16:04] <fsphil> aquasail?
[16:04] <eroomde> keel
[16:04] <fsphil> I've no idea what they're called now that I think about it
[16:04] <fsphil> that's it
[16:04] <eroomde> yeah you could put a strain guage in place
[16:04] <eroomde> turn the sail into the wind if the strain is too high
[16:05] <eroomde> but equally, might just be strong enough to not be an issue
[16:05] <nigelvh> I would go that route.
[16:05] <nick_> I've been thinking of making an autonomous boat for the pond or a canal, not the atlantic though.
[16:05] <nigelvh> Just make it beefy.
[16:05] <eroomde> the issue would be prevening capsize
[16:06] <fsphil> put the batteries into the keel
[16:06] <nigelvh> Or a weight
[16:06] <fsphil> or make the keel and sail interchangable
[16:06] <fsphil> have it work both ways
[16:06] |ezra| (~|ezra|@75-140-3-62.static.rvsd.ca.charter.com) joined #highaltitude.
[16:06] <nigelvh> Easy to test. Put it in upside down, does it right itself?
[16:06] <SamSilver> ooh brainstorming
[16:07] <eroomde> i think both ways would be faff
[16:07] <eroomde> u need an anemometer and wind vane
[16:07] <fsphil> yea
[16:07] <fsphil> not gonna work
[16:07] <eroomde> having a submerged one would be really draggy :)
[16:07] <fsphil> it would just end up flat on the surface
[16:08] <nick_> Don't you need to have some measurement of the wave directionn to avoid capsizing too?
[16:08] <nick_> You want to sail into the waves.
[16:08] <nigelvh> Just build it to be impossible to capsize
[16:08] <eroomde> do you really though?
[16:08] <nick_> Make it a submarine!
[16:08] <nigelvh> Or totally sealed and have a weight off the bottom.
[16:08] <nick_> I'm not sure how submarines can sail though...
[16:08] <fsphil> nick_: wings
[16:09] <eroomde> id just make it passively robust and actively trying to make headway
[16:09] |ezra| (~|ezra|@75-140-3-62.static.rvsd.ca.charter.com) left irc: Client Quit
[16:09] <fsphil> someone made one, it drops and the wings push it forward
[16:09] <fsphil> then it tilts the wings the other way, rises back up and that propells it forward again
[16:09] <fsphil> so it's just constantly rising and diving
[16:09] <fsphil> really cute idea
[16:09] <nick_> OK
[16:10] <SamSilver> fsphil: i am trying to find a link for that
[16:10] <fsphil> can't remember what it's called now
[16:10] <nigelvh> I recall the device you're referencing.
[16:10] <SpeedEvil> density hydroplane?
[16:10] Action: SpeedEvil forgot too
[16:10] <SamSilver> what fsphil was describing crossed a large ocean
[16:10] <eroomde> some ex yahoo millionare was funding it right

[19:46] <eroomde> i can't even imagine it
[19:47] <nick_> Brain Cox doesn't seem to have many fans within physics.
[19:47] <Laurenceb_> hehe
[19:47] <eroomde> Brian*
[19:47] <Laurenceb_> his programs are quite content free
[19:48] <eroomde> they're probably fascinating if you aren;t familiar with the stuff
[19:48] <daveake> Must say I probably had more "aaah"'s in that video that eroomde linked to last week than all of BC's progs together
[19:48] <eroomde> but yeah if you have done some science of know any maths, having stuff described in hyperbolic english, where maths is the much more beautiful language, is damn frustrating
[19:48] <eroomde> which video did i like to last week?
[19:48] <eroomde> show me :)
[19:49] <Lunar_Lander> well I have to say that Stargazing Live and that quantum mechanics lecture wasn't content free
[19:49] <daveake> or maybe not you :)
[19:49] <fsphil> I liked the quantum lecture he did
[19:49] <daveake> Let's see if I can get my memory cells working
[19:49] <nick_> (personally I also think that there's a fair amount of resentment of his position)
[19:49] <fsphil> in particular his description of why electrons have the distance they do from the center of an atom
[19:49] <nick_> Permanent positions are very rare...
[19:50] <daveake> Laurence Krauss
[19:50] <daveake> Maybe I read it elsewhere
[19:50] <Laurenceb_> nick_ his professorship?
[19:50] <nick_> yes
[19:50] <Laurenceb_> where is it?
[19:50] <Laurenceb_> i forgot
[19:50] <nick_> He got a professorship at a young age because of his outreach.
[19:50] <nick_> Manchester I think
[19:50] <nick_> Either there or Liverpool
[19:51] <Laurenceb_> ah
[19:51] <nick_> for a while he did physics and some outreach.
[19:51] <Laurenceb_> well my supervisor got a professorship at about 40, and knows next to nothing
[19:51] <Laurenceb_> but thats EEE
[19:51] <nick_> Then he seemed to just do flying around the world for pointless 10 second clips.
[19:51] <Lunar_Lander> yea Manchester
[19:52] <Lunar_Lander> OH SHIT you mean that he isn't worth it anymore?

[19:53] <Lunar_Lander> Upu, I got the 100 nF ceramic capacitors

[19:54] <Laurenceb_> *leaf
[19:54] <Lunar_Lander> by Cox?
[19:54] <Laurenceb_> no, my supervisor
[19:54] <Lunar_Lander> ah
[19:54] <Laurenceb_> can you see the problem with the idea?
[19:55] <Laurenceb_> hes published a paper on an automated weather dependant lighting conditions detector
[19:55] <Lunar_Lander> yea
[19:55] <Lunar_Lander> that is not high-level research
[19:56] <Laurenceb_> at least the university is good and i know what im doing so i dont care
[19:56] <Lunar_Lander> yea
[19:57] <nick_> (people also don't really like how he got his TV show. And everyone hates D:REAM
[19:57] <nick_> )
[19:57] <fsphil> I quite liked that song :p
[19:57] <Laurenceb_> i was offered a PhD at oxford but i prefer more engineeringy stuff
[20:00] <Laurenceb_> i realise now that but so many places are just doing daft stuff
[20:02] <nick_> It's quite annoying given the current funding cycle phase.
[20:03] <Lunar_Lander> OK
[20:03] <Lunar_Lander> so brian cox is not good after all?
[20:14] <nick_> He seems to be good at what he does.
[20:14] <nick_> But what he does is not what scientists do.

[21:06] <eroomde> and to disguise the train as fog so you can't see it from the air

[21:08] <Lunar_Lander> the crap electric taxi
[21:08] <eroomde> except clive james, being on the news a lot recently as everythone thought he was about to die, has completely ruined it for me

[21:08] <Lunar_Lander> ohhh
[21:09] <Lunar_Lander> the taxi explosion was sooo crappy
[21:09] <eroomde> as i read one of his articles from the 80s where he describes arnold schwarnegger as a brown condom stuffed with walnuts
[21:09] <Lunar_Lander> XD
[21:09] <Upu> http://www.imdb.com/title/tt1386703/

[21:12] <Upu> sadly most cars based on those engines are rubbish
[21:12] <eroomde> 'This is a 24-litre V12 and capable of theoretical 300mph.'
[21:12] <eroomde> lol
[21:13] <Upu> yeah right
[21:13] <eroomde> i'm not sure which theory he subscribes too
[21:13] <Lunar_Lander> OHHHH the Belgium joke!!!
[21:13] <daveake> Though this is the best car engine sound ever. http://www.youtube.com/watch?v=fZMPDCNyQxE
[21:13] <Upu> when you put wings on it
[21:13] <eroomde> theory of don't understand physics i suspect
[21:14] <daveake> 1.5 litre V16. Awesome. While it worked that is.
[21:16] <Upu> right dog walk bbs
