[00:02] <nigelvh> Also, looks like you had a good flight. Went down sometime yesterday evening?
[00:02] <KT5TK_QRL> Yes, it was fun. Likely a slight loss of He
[00:03] <KT5TK_QRL> It came down when the sun went down
[00:03] <nigelvh> Yeah, didn't look like it was dropping all too quickly.
[00:03] <nigelvh> Was that with just the 100mW out?
[00:03] <KT5TK_QRL> Yes. No additional amplifier

[09:11] <craag> Oh, no GPS power saving?
[09:12] <gonzo_> measures about 65ma gps unlocked, so guess 50MA with it locked. And conservative mAh on the batts, down to 1.1V/cell. About 24hr
[09:12] <gonzo_> no power saving
[09:12] <gonzo_> that can be on the next itteration of the tracker. As the pic I use is getting obsolete

[10:31] <craag> G0TDJ_Steve: I had another go with the camera on Dave's evening flight https://www.thecraag.com/photos/index.php?album=buzz-zurg-hab-photography/
[10:31] <craag> This time the sun was behind me and setting, as opposed to up behind the balloon on the LOHAN flight.
[10:33] <G0TDJ_Steve> craag: Roger, saw those. You must have posted the link before. Well done spoting the balloon so high up
[10:33] <craag> hehe, I had a protractor and hung a ruler vertically down to get the elevation.
[10:34] <G0TDJ_Steve> Wow Neat
[10:34] <craag> Then we had a very indecisive compass, so I ended up scanning in swathes through the viewfinder til I found it!
[10:34] <daveake> nice :)
[10:35] <craag> Very visible when the last photo was taken though. Bright orange fireball in the dark sky.
[10:35] <G0TDJ_Steve> It worked though
[10:35] <craag> It did. The main issue was tripod vibration.
[10:36] <craag> I took 407 photos for Dave's flight, and those were the only good ones.
[10:36] <craag> The light was low, and any higher ISO produced noise that was rather large with respect to the balloon!
[10:37] <G0TDJ_Steve> You did well Philip
[10:37] <craag> :)
[10:37] <mfa298> just before burst of the 2nd flight the ballon even showed up on a phone camera although you wouldn't spot it unless you knew it was there and very visible to the naked eye!
[10:38] <craag> My brother said they looked 'reasonable considering' which is the best compliment I've ever got for a photo from him!
[10:38] <G0TDJ_Steve> LOL Typical photographer ;-)
[10:39] <mfa298> I wonder if next time (if there is a next time) whether having an external screen and much lower tripod would help.
[10:39] <mfa298> and ideally remote shutter control.
[10:39] <G0TDJ_Steve> Stabilising lens...
[10:39] <craag> Yeah, I'll make up a remote shutter cable if I do it again.
[10:40] <craag> Although actually I got good results by holding the camera tight to reduce the vibration.
[10:40] <craag> THere was just too much give in the tripod mount.
[10:40] <craag> G0TDJ_Steve: Stabilising 500mm lens... not sure I can afford that!
[10:40] <bertrik> craag: nice photos, did you have some kind of automatic tracker to keep it in view?
[10:40] <G0TDJ_Steve> LOL :D
[10:41] <craag> bertrik: No, a home-made sextant and a compass :)
[10:43] <craag> G0TDJ_Steve: I was discussing with someone the other day, wondering if at that range the atmospheric scattering was now the limit on how sharp the photo could be?
[10:43] <gonzo_> bonzo7 just waiting for gps lock
[10:43] <G0TDJ_Steve> Cheers gonzo_
[10:43] <G0TDJ_Steve> Yeah, Philip, that could well be an issue
[10:43] <craag> I took many photos moving slowly through manual focus range, and none came out any sharper.
[10:44] <G0TDJ_Steve> At that range, you might as well be focused at infinity
[10:44] <craag> Inifinity on that lens wasn't optimal..
[10:44] <G0TDJ_Steve> gonzo_: Not on Tracker yet?
[10:44] <G0TDJ_Steve> Oh, OK
[10:44] <charolastra_> where will bonzo7 launch?
[10:44] <craag> That's a mistake I made the first time, hence why there's only a few good photos, only realised towards the end!
[10:44] <gonzo_> time locked

[11:01] <gonzo_> it's proven code

[11:04] <gonzo_> just staked the payload down with a brick. give it a more stable view of sky to get lock

[11:05] <LeoBodnar> Brick always helps when it comes to GPS

[11:36] <gonzo_> I holw so. Best yet for me is mt far over 3k for foil
[11:36] <gonzo_> almost!
[11:36] <bertrik> 4500m is probably too low to get the signal at the netherlands

[11:44] <G0TDJ_Steve> Magic
[11:45] <LeoBodnar> gonzo_: your average ascent rate from launch is 0.61m/s - very good
[11:45] <gonzo_> that is excellent. Initially I was worried it was too fast
[11:46] <gonzo_> the scales used were prob not ideal
[11:46] <mfa298> very slight drift up in frequency but hardly noticable - although that could be due to the slow ascent rate

[12:28] <mikestir> afternoon all. I've published my web sdr code if anyone's interested: http://www.mike-stirling.com/webradio/
[12:29] <SpeedEvil> (I would note that for a single pole mast - you want to get C24, not C16 timber - or select the C16 timber to be free of strucutrally important knots.
[12:29] <mikestir> it's buildable and works, but the DSP needs a bit of work still, particularly around the channel filter
[12:29] <SpeedEvil> What does it do?
[12:30] <Rob_m0dts> thanks mikestir
[12:30] Action: SpeedEvil should probably have been reading backlogs.
[12:30] <mikestir> as it stands, am and fm rx on a single channel, but fully web based
[12:30] <mikestir> the server supports multiple rxes already - just need to get it incorporated into the ui
[12:30] <SpeedEvil> Hmm.
[12:30] <craag_M0DNY> Upu: Goodie bag just arrived, thanks for quick delivery!
[12:30] <SpeedEvil> Interesting.
[12:31] <mikestir> and once the filters are fixed it will do sideband, then I'm intending to add digimode decoders into the stack as well

[12:33] <SpeedEvil> Or, indeed the display or camera connectors.
[12:34] <mikestir> suppose it would be theoretically possible to stream rf samples over the mipi interface
[12:34] <Kevin-G7UXW> what freq is STS5-b on ?????
[12:34] <SpeedEvil> Alas deeply annoyingly all of that is quite impossible without lots more openness which seems unlikely.
[12:34] <craag_M0DNY> Kevin-G7UXW: It's landed and been recovered I believe.
[12:35] <G0TDJ_Steve> Kevin-G7UXW: Confirmed
[12:35] <SpeedEvil> MIPI is probably 'cooked' enough in hardware that you'd need an external FPGA or CPLD to talk to it.

[13:26] <bertrik> Wouter-[pa3weg]: it's pretty far away
[13:26] <GMT> and still quite low
[13:26] <GMT> it's floating , but more like bouncing along
[13:27] <Lunar_LanderU> hi radim_OM2AMR_
[13:27] <radim_OM2AMR_> hi Lunar_Lander
[13:27] <Wouter-[pa3weg]> it might float our way...+ the weather is weird, maybe DX possible

[13:27] <gonzo_> the lift was marginal, so quite poss the wx/air movements is affecting it
[13:27] <radim_OM2AMR_> great :-) after todays launch :X
[13:28] <radim_OM2AMR_> :-D
[13:28] <Lunar_LanderU> yea
[13:28] <Lunar_LanderU> what happened?

[13:28] <chrisg7ogx> Bonzo7 comes and goes here raining hard
[13:29] Action: Wouter-[pa3weg] is back to watching some apollo13 footage (from the original event, not the movie)
[13:29] <chrisg7ogx> i liked the movie

[13:30] <chrisg7ogx> nearly 90mm and ghour?
[13:30] <Lunar_LanderU> yea
[13:30] <Lunar_LanderU> it was raining like crazy
[13:31] <Lunar_LanderU> and that was when I decided to leave my umbrella home as it was still quite warm when I left

[13:43] <Rob_m0dts> mikestir hi
[13:43] <mikestir> hi. I replied to your email. should be an easy fix
[13:43] <Rob_m0dts> mikestir thanks for email will give it a go ta.
[13:44] <mikestir> improving the channel filter is next on my list, after which it should become a lot more useful
[13:45] <mikestir> at the moment it's fixed bandwidth and wider than ideal for AM and NFM, too narrow for WFM
[13:45] <mikestir> could to have others testing though
[13:45] <mikestir> good*
[13:47] <mfa298> mikestir: I've tried compiling on my pi but compile fails at present, not gone any further than testing than that so far (could be due to using the packaged http lib rather than compiling that from source)
[13:47] Nick change: GMT -> GMT_afk
[13:47] <Willdude123> Hi everyone.
[13:48] <mfa298> could also be a variable sizing issue on the pi.
[13:50] <Willdude123> Upu did the saleae logic help you a lot with the priblem you were having the other day?
[13:51] <mikestir> mfa298: most of the debian-based distros seem to have an ancient version of the httpd library in their repos

[13:53] <M3EAV> really heavy PHT rain falling here now
[13:53] <M3EAV> PHAT RAIN
[13:53] <Lunar_LanderU> LOL
[13:54] <LeoBodnar> It needs to dry a bit and get higher
[13:54] <chrisg7ogx> if Bonzo7 stays healthy it shouldm give the trackers in the UK a good work out!
[13:54] <mfa298> I think this might be a raspberry pi variable size issues (it's a LOG_DEBUG message with %lu and size_t) - just changed the code and it seems to be compiling further
[13:54] <mikestir> oh yeah that's the same thing that Rob_m0dts had
[13:55] <mikestir> it's due to size_t being a different size on 32-bit systems - I have only been building on 64-bit
[13:55] <mfa298> I also found that ./configure didn't notice that lame/lame.h was missing (only found when trying to compile)
[13:55] <mikestir> and I'm probably being optimistic having -Wall -Werror turned on at this stage!
[13:55] <chrisg7ogx> there's a shed load of rain with our name on it over the Carentan peninsula
[13:56] <LeoBodnar> On the positive note this has been quite a productive week for foil balloons
[13:56] <Rob_m0dts> mikestir fix worked, now built..will try it out!
[13:57] <mikestir> great. don't forget to install jquery and jquery ui
[13:57] <mikestir> and use chrome - for some reason mouse events don't work on the tuning display in FF
[13:57] <Rob_m0dts> ta
[13:57] <bertrik> mikestir: try cppcheck too, it's often find easy-overlooked little bugs
[13:58] <mikestir> bertrik: thanks I'll take a look at that. I have run it through valgrind at a few points during development - that's a very useful tool
[13:58] <LeoBodnar> I got FUNCube Pro+ dongle. What is the best package to use with it on Mac OS X?
[13:59] <LeoBodnar> No, it's not Windows or Linux :)
[13:59] <LeoBodnar> But on the second thought...
[14:00] <LeoBodnar> Can one spray foil balloons with water repelling stuff?
[14:00] <mikestir> mfa298: lame isn't using pkgconfig and you're right it doesn't check for the headers, only the library. I'll make a note of that one
[14:01] <LeoBodnar> C'mon BONZO7, you are expected at 7000m, don't get distracted by whatever you do there at 3000
[14:03] <craag_M0DNY> LeoBodnar: Before you came along, no-one had floated foils at anything near 7000.
[14:03] <craag_M0DNY> jcoxons tended to be ~4500m
[14:04] <LeoBodnar> It has been so long ago!
[14:04] <LeoBodnar> Nearly a month ago! XD
[14:04] <craag_M0DNY> :O
[14:04] <craag_M0DNY> Didn't you say you have one filled ready to go?
[14:05] <LeoBodnar> B-2 was my first foil and it was 2nd of July
[14:05] <Herman-PB0AHX> BONZO7 must go up higher for me
[14:06] <craag_M0DNY> I have hwoyee 100gs arriving next week
[14:06] <LeoBodnar> I am deep into chasing GPS timing gremlins atm
[14:06] <LeoBodnar> With stockings?
[14:06] <craag_M0DNY> will fly one as burst to check tracker (probably with natural gas)

[14:37] <Steve_2E0VET> Willdude123, yes
[14:37] <mikestir> Rob_m0dts: you have to tap the digits to tune on a touch-screen, rather than mouse wheel. It's fiddly but works for now. A proper app would be better
[14:37] <mikestir> mfa298: I didn't think it would work. Should be ok with FCD though once that's implemented
[14:37] <Willdude123> Steve_2E0VET: What's the problem?

[14:41] <mikestir> obviously all this will be configurable at run time once I sort out the filter!

[15:03] <mfa298> mikestir: halving the samplerate it still looses data, and other sample rates seem to lead to a segfault. will be interesting to try once it works with an FCD Pro+ - I might have to try a virtual machine and see how well it works like that.

[15:18] <mfa298> Steve_2E0VET: I think you'll find the hardware serial pins are fixed, and for software serial you'll need to define which pins to use (probably the pins 4/5). Although I've never used an arduino so could be wrong!

[15:34] <ibanezmatt13> I'm drawing a schematic for an ATMEGA328 to be used with an NTX2 and I'm trying to work out how I should connect the two. I can either use PWM or a resistive divider circuit like on the wiki. If I use PWM, is it just a case of connecting a PWM pin to the NTX2?
[15:35] <mfa298> ibanezmatt13: i believe so.
[15:36] <ibanezmatt13> mfa298: I guess there's not much code out there for using PWM and RTTY? If so I may be better using the resistive divider circuit. Only issue is, I'm not sure what resistor values I should use for 3v3 as the wiki guide is run off 5v
[15:36] <mfa298> also remember the pwm pins can also be used for general io so you could use the same pin but with a resistor divider setup
[15:36] <fsphil> ibanezmatt13: use the normal method with the pwm pin
[15:36] <fsphil> you can configure the pwm to do either
[15:36] <fsphil> which is what mfa298 said :)
[15:36] <ibanezmatt13> fsphil: that's what I'm planning on doing
[15:36] <ibanezmatt13> :)
[15:36] <fsphil> I'm a bit lagged
[15:36] <daveake> No wonder you're warm
[15:36] <ibanezmatt13> I'm just trying to figure out the resistor value for R3. Will it be the same as on my Pi setup?
[15:36] <mfa298> fsphil: I think we said that at the same time (so great minds :D )
[15:37] <cyclops_> test
[15:37] <mfa298> ibanezmatt13: should be as that was all 3v3. You can always change the resistor values later (you should be able to get them on the same footprint)
[15:38] <ibanezmatt13> Yeah, I'll just follow my own for now. Then I can always test it before I do anything more permanent. Should be ok, thanks :)

[15:58] <ibanezmatt13> Upu, for the board I'm making, should I use the TPS76633D LDO?
[15:59] <Upu> I would use a step up
[15:59] <chrisstubbs> ^good advice
[15:59] <ibanezmatt13> Step up?
[15:59] <Upu> harder to solder but you can run it off 1/2 batteries
[15:59] <Upu> yeah LDO reduces the voltage
[15:59] <Upu> step up boosts it up
[15:59] <Upu> so you could stick 1.5V
[15:59] <Upu> and get your 3.3V
[15:59] <Upu> i.e 1 battery
[15:59] <Upu> in theory
[15:59] <ibanezmatt13> Aaah, that's great
[15:59] <Upu> however
[16:00] <Upu> they are more complex and harder to solder
[16:00] <ibanezmatt13> What makes them more complex?
[16:00] <Upu> I would use a TPS61201
[16:00] <Upu> and follow the data sheets suggested layout guide lines
[16:01] <ibanezmatt13> Does that component exist in Eagle already?
[16:01] <chrisstubbs> upu do you solder those by hand or hot air?
[16:01] <Upu> hand
[16:01] <ibanezmatt13> found it. I'll have a read up on it
[16:01] <Upu> unless I screw it up then a blast of hot air fixes it
[16:02] <chrisstubbs> looks like fun to do
[16:02] <chrisstubbs> long lands?
[16:02] <ibanezmatt13> Upu: TPS61201DRCT ?
[16:02] <Upu> yeah
[16:03] <Upu> if you want an example go download Sparkfuns LipPower board
[16:03] <Upu> http://www.sparkfun.com/datasheets/Prototyping/LiPower-v11.zip
[16:03] <jdtanner> Has Bonzo burst?
[16:03] <ibanezmatt13> Thank you
[16:04] <ibanezmatt13> TPS61200 Upu? That the same sort of thing?

[16:04] <Upu> the 61200 is just the variable voltage one
[16:04] <ibanezmatt13> so the 01 version is fixed to step up to 3v3?

[16:15] <ibanezmatt13> For the schematic though...
[16:15] <Upu> its pretty much identical
[16:16] <Upu> just don't have the 2 resistors from FB -> VOUT
[16:16] <Upu> FB is just wired to VOUT
[16:16] <ibanezmatt13> Ah ok. I'll just use the variable one for my schematic then. Hopefully it shouldn't be too difficult to grasp :)
[16:17] <chrisstubbs> Laurenceb, the idea of a bag sealer type thing has been thrown around. Will that not work?

[17:06] <LeoBodnar> And it did not even start getting superpressured so no real stress on the envelope. There would be a knee on ascent profile when envelope is fully inflated

[20:02] <Belleas> how is everyone tonight?
[20:03] <LeoBodnar> daveake: Local Waitrose de-energized thanks for heads up!
[20:04] <LeoBodnar> *de-energizered
[20:05] <Belleas> just thought i would throw a question out there. I'm in the final stages of testing my GPS/NXT2 tracker and wondered how others had made the circuit more stable. Ive seen people keep to using breadboards but i am concerned of a connection coming loose on landing. This in mind, i am rubbish at soldering. Anyideas?
[20:05] <daveake> :
[20:05] <daveake> )
[20:05] <daveake> They had 9 packs in Newbury
[20:06] <daveake> Stock -= 8
[20:06] <LeoBodnar> Now waiting for AA to pounce on.
[20:06] <mfa298> I'd hope no one has flown a tracker on breadboard
[20:06] <daveake> ditto :)
[20:06] <mfa298> it's well known at causing issues on the bench
[20:06] <LeoBodnar> stock -= 2*int(stock/2)
[20:07] <daveake> 8 packs I mean not 8 cells :)
[20:07] <LeoBodnar> That's what I mean too :)
[20:07] <daveake> I know you do just checking you knew I did :)
[20:07] <Belleas> maybe the videos i watched were in test phase then. But what options do i have(if any) if soldering isnt my game
[20:08] <daveake> Learn to solder :p
[20:08] <Belleas> i knew someone was going to say that :)
[20:08] <mfa298> Soldering isn't hard and you can get stripboard which is similar in layout to breadboard
[20:08] <daveake> It's that or get someone to do it for you
[20:08] <daveake> It's not hard and it's a useful skill
[20:09] <daveake> But breadboard isn't fit for purpose IMO and is absolutely definitely not anywhere near a sniff of being a good idea in a payload
[20:09] <Belleas> ok, ill ive it another crack. i havent done it inyears and last time i tried... lets just say it was not a success
[20:10] <mfa298> just make sure you've got a reasonable iron, wet sponge to clean the tip, and some decent solder.
[20:11] <mfa298> have a practice with components that don't matter first
[20:11] <Belleas> i think i better break this to the mrs gently
[20:11] <Belleas> yeah, i might get one of those kits from maplins for beginners
[20:11] <Belleas> make your own time machine or something like that
[20:12] <cde> SchmartBoard, also adafruit has breakout pcb
[20:12] <cde> smd is in fact not that hard
[20:12] <cde> (unless you want to have it done perfectly on the first try)
[20:13] <LeoBodnar> Make time machine first and then get soldering kit. They were cheaper in the past.
[20:16] <Belleas> or i could go back to school and learn again :)
[20:16] <Belleas> cheers cde ill look into that

[21:42] <Laurenceb_> about 70N
[21:42] <Laurenceb_> that makes things a lot easier

[21:47] <LeoBodnar> I think the fact that its's a stepper makes controlling it so much easier
[21:48] <Laurenceb_> yeah that was my reason for going with a stepper in the first place

[21:48] <Laurenceb_> it was a nightmare

[21:49] <Laurenceb_> would actually oscillate by itself

[21:50] <LeoBodnar> I would have suggested linear AC motor but they are massive and need a linear encoder to even start moving

[21:50] <SpeedEvil> Indutrack looks funky.
[21:50] <SpeedEvil> Totally passive self-supporting maglev.
[21:51] <Laurenceb_> i was wondering if it could be made thin film
[21:51] <LeoBodnar> Laurenceb needs controlled thrust or position control
[21:51] <Laurenceb_> well i need controlled pressure/time
[21:52] <LeoBodnar> Is Indutrack superconductive?
[21:52] <Laurenceb_> so you can enter in pressure/time profiles and itll do it
[21:52] <Laurenceb_> no
[21:52] <SpeedEvil> LeoBodnar: No - aluminium/copper Litz.

[21:52] <SpeedEvil> LeoBodnar: Think a ladder made from massive amounts of Litz wire.
[21:53] <SpeedEvil> LeoBodnar, With large permenant magnets on top of it. When you push the magnets along over about walking pace, they lift off.
[21:53] <LeoBodnar> Ah, inductive currents?
[21:54] <Laurenceb_> if you could combine skytran with inductrac
[21:54] <Laurenceb_> or maybe they already did
[21:54] Action: Laurenceb_ lt;dr
[21:55] <SpeedEvil> They seem to be saying indutrac without actually saying it.
[21:55] <SpeedEvil> I do kinda wonder what happens if you swap the shiny induction track for bicycle tyres.
[21:55] <SpeedEvil> I mean - no - it's not shiny and sexy anymore.

[22:44] <cyclops> Just as a backup?
[22:44] <LeoBodnar> Bummer, it looks like Agilent oscilloscopes don't like being dropper on the floor (twice)

[22:50] <craag> Just don't rely on it!
[22:50] <cyclops> and pretty cheap

[22:56] <craag> Kudos to you for putting soo much into a big one!
[22:56] <cyclops> The tracker you use in pico... How expensive is it?
[22:57] <cyclops> And you fly floaters or recover the payload?
[22:57] <craag> Comes out at about 40-45 pounds per tracker.
[22:57] <craag> I have only flown and receovered so far.
[22:58] <craag> might be attempting a float in the coming weeks, but I'm going to make sure it works before I throw the tracker away!
[22:59] <cyclops> Yeha,
[22:59] <cyclops> Im now trying to convince people to follow my payload.
[22:59] <craag> Does mean I can't fly any cameras or anything like that, so I do it more for the technical challenge than anything else.
[23:00] <cyclops> As the dont know much about DL-fldigi and space near.us
[23:00] <cyclops> is being rather complicated
[23:00] <craag> I bet yeah
[23:01] <craag> Best thing is probably to put a guide together.
[23:01] <cyclops> I did
[23:01] <cyclops> Translated the wiki article "Tracking guide" into spanish
[23:02] <craag> If you can, then doing a little workshop where you sit your payload on the table transmitting, and people bring in their radio and laptop and have a go at setting up to receive it.
[23:02] <cyclops> That explains the soft you have to use and how to setup
[23:02] <cyclops> Might be difficult to do it here
[23:02] <SpeedEvil> craag: Especially as you can use bare dongles
[23:02] <craag> Also people can take a look at what you're flying, and potentially get more interested.
[23:02] <craag> (depends on geographic distance of people of course)
[23:03] <craag> SpeedEvil: Yep.
[23:03] <craag> And helping someone set it up is soooo much easier if you're there, rather than over IRC.
[23:04] <cyclops> Yes, but in spain is pretty difficult to do that

[23:26] <cyclops> Currently triying to convince some to put the info there

[23:29] <cyclops> Good idea
[23:30] <mfa298> if you look at the uk contingent on here the majority are licensed hams, around half were licensed before they got into balloons, the other half got licensed because of the ballooning (and the license doesn't currently help with balloons as we're not allowed amateur radio from the air)
[23:31] <cyclops> Yes but as i've been told, in uk its cheaper and easier to get one
[23:32] <cyclops> I tried to get one, but i had to pay about 200¬+20¬ of the exam
[23:32] <cyclops> But in the future, i will

[23:34] <mfa298> and if you appear keen (even if it could be several years before you do the exam) they will hopefully pick up on it.
[23:35] <cyclops> Ill do then
[23:36] <mfa298> it might also be worth finding out if there's a magazine for amateur radio that people get and write a short article for them (although that might be something for after the launch)
[23:36] <cyclops> Yes
[23:36] <cyclops> i plan if everithing goes well, to send the images to the TV and magazines
[23:37] <cyclops> Because I dont tell them before, just in case something goes wrong
[23:37] <cyclops> Its added pressure
[23:38] <LeoBodnar> You are too sensible for a typical balloonist cyclops !
[23:39] <cyclops> LeoBodnar: Well I really think on all the possible consequences
[23:39] <cyclops> And I dont like to sel the bears skin without having killed it
[23:40] <mfa298> I was also thinking there might be a magazine dedicated to amateur radio (we've got Radcom which is done by the rsgb and practical wireless here) which potentially would have been a good way to get more radio people tracking if you'de got something in them earlier
[23:44] <cyclops> Yes
[23:44] <cyclops> But i think im kinda late for that

[23:48] <SpeedEvil> http://www.youtube.com/watch?v=qy1w6rTpC2g - sort-of-on-topic.
[23:48] <SpeedEvil> Levitation.
[23:51] <cyclops> cool
[23:54] <Laurenceb_> untrasonic ?!
[23:54] <Laurenceb_> thats different
[23:56] <SpeedEvil> Indeed.
[23:56] <SpeedEvil> Also it seems a simple lens could vastly improve it
[23:59] <cyclops> *get
[23:59] <cyclops> I have to ger permissions, right?
[23:59] <cyclops> Ah and to put my payload on Spacenear
