[03:16] <W0OTM> howdy
[03:17] <nv1k> howdy
[03:17] <nv1k> making progress towards next iHab?
[03:17] <W0OTM> yeah
[03:17] <W0OTM> launch this weekend
[03:18] <W0OTM> did our first payload systems test today
[03:18] <W0OTM> had a small glitch in the CW keyer, but glad we found it now and got it fixed
[03:20] <nv1k> thats good
[03:20] <nv1k> we are hoping for a launch this weekend as well but not sure if it will work or not
[03:21] <nv1k> myself an another senior team member are busy administering an amateur radio exam saturday morning
[03:25] <W0OTM> ahhh, well good luck
[03:25] <W0OTM> iHAB-2 is sponsored by QRP ARCI,
[03:25] <W0OTM> looking forward to alot of signal reports from the 20m beacon
[03:26] <W0OTM> 1.6w from a 9V battery
[03:26] <W0OTM> runs 6hrs
[03:26] <W0OTM> im really excited to see it
[03:26] <W0OTM> im going to webcast the launch
[03:27] <nv1k> nice
[03:27] <nv1k> just cw on the 20m?
[03:27] <W0OTM> yeah, and the usual APRS
[03:27] <nv1k> cool
[03:27] <W0OTM> on 144.34
[03:28] <nv1k> i finished up a 20m bidirectional CW tranceisver this weekend for our upcoming long duration flight
[03:28] <nv1k> looking into perhaps rtty or psk or domino now
[03:28] <W0OTM> nice
[03:29] <nv1k> i wish i had more time to focus on HAB
[03:29] <W0OTM> I think this winter I want to put a 2.4GHZ wifi AP in, and see what signal strengths are
[03:30] <nv1k> i have a bunch of updates almost ready for our prediction/tracking software but homework and other lab projects keep getting in the way
[03:30] <W0OTM> LOL, understandable! I sold my software company so I could spend more time playing with HAB/Ham Radio
[03:31] <W0OTM> it has become an addiction for me
[03:31] <nv1k> heh
[03:31] <nv1k> the actual launching is so much the addiction for me as the technical challenges behind it
[03:33] <nv1k> developing the best possible electronics, predictions algorithm, etc
[03:41] <W0OTM> well, off to bed. spent enough time in the shack tonight.....ttul

[10:40] <m1x10> I got a stupid question
[10:40] <m1x10> my transmitter's antenna
[10:40] <m1x10> is sending APRS...ok
[10:41] <m1x10> but its tuned on 50cm 1/4»
[10:42] <m1x10> so that antenna can also receive at 50cm. Right?
[10:42] <m1x10> What happens to the received signal?
[10:43] <m1x10> the radiometrix HX1 only transmits. The received radio from the ant isnt it flowing to the HX1's TX pin?
[10:43] <m1x10> and what does the HX1 to this received radio?
[10:45] <juxta> yes, the antenna will be capable of receiving too: http://en.wikipedia.org/wiki/Antenna_%28radio%29#Transmission_and_reception
[10:46] <juxta> as for an incoming transmission, nothing will happen. even if there was a very powerful transmission on the same frequency, the voltage at the TX pin on your module would only be millivolts
[10:47] <juxta> the same thing applies with headphone/speakers - you can use a set of earbuds as a microphone, but if you shout into them while they're playing music, nothing much will happen
[10:47] <Darkside> juxta: my advanced exam will probably be on the 9th
[10:48] <Darkside> the day before horus 8 :P
[10:48] <juxta> Darkside, awesome :)
[10:48] <juxta> yeah, PH emailed me to say hehe
[10:48] <Darkside> heh
[10:48] <Darkside> i'll probably stick with RTTY300 for the telemetry
[10:48] <Darkside> or maybe drop down the baud rate a it
[10:48] <Darkside> juxta: is there any change you can rig up a dipole antenna or something?
[10:48] <Darkside> like, at home
[10:50] <m1x10> juxta in simple words you say that the received radio will become some few millivolts to the TX pin.
[10:50] <Darkside> probably less than millivolts
[10:50] <m1x10> that mV is so little to cause something to the pin
[10:50] <Darkside> microvolts maybe
[10:50] <m1x10> yeah
[10:51] <m1x10> but if that happend at the period that im transmitting?
[10:51] <juxta> nothing will happen
[10:51] <Darkside> lol
[10:51] <m1x10> :p
[10:51] <juxta> to your transmitter anyway
[10:51] <Darkside> m1x10: there will be some kind of induced noise at teh antenna at all times
[10:51] <Darkside> thermal noise, for instance
[10:51] <juxta> if there's another transmission at the same time as yours, then you will have a collision and it might not be valid data at a receiving station
[10:52] <juxta> but APRS deals with this
[10:52] <Darkside> i like how the glider FLARM systems deals with this
[10:52] <m1x10> my transmit signal wont get any interference from the received signal?
[10:52] <Darkside> it transmits every 2 seconds + a random time between 0 and 1.5 seconds
[10:53] <Darkside> m1x10: no, there will be no problems
[10:53] <m1x10> why?
[10:53] <Darkside> :/
[10:53] <m1x10> cause the received is so little?
[10:53] <Darkside> because there won't be? :P
[10:53] <Darkside> mm
[10:53] <m1x10> aaa
[10:54] <m1x10> any expert explanation ? :p
[10:55] <m1x10> Im asking cause im thinking of adding a receiver radio on the board
[10:55] <m1x10> to send commands :P
[10:56] <m1x10> i have plenty of room to my new pcb
[10:56] <m1x10> so im adding things
[10:56] <m1x10> that would possible need
[10:57] <juxta> if you're going to do RX on the same frequency you'll need to leave gaps in your transmission where you power down your transmitter
[10:57] <juxta> then when you have a gap you can uplink in to the balloon
[10:57] Laurenceb_ (80f3fd6c@gateway/web/freenode/ip.128.243.253.108) joined #highaltitude.
[10:57] <m1x10> juxta the only thing i can control on the HX1 is the PTT
[10:58] <m1x10> im doing like ptt_on(), tx(), ptt_off()
[10:59] <juxta> sure, so you would key down, leave a few seconds
[10:59] <juxta> and in that time your ground station could transmit in
[11:00] <m1x10> yeah
[11:00] <m1x10> im thinking exactly the same
[11:00] <m1x10> i will know the time the balloon is not Txing
[11:00] <m1x10> so i can send that period
[11:01] <m1x10> juxta want to see my super-duper-noober pcb ?
[11:01] <juxta> sure
[11:01] <m1x10> :0
[11:01] <m1x10> :)
[11:01] <m1x10> wait
[11:01] <juxta> Darkside, yeah I can probably string a dipole up
[11:01] <m1x10> its the best i can do..
[11:01] <juxta> but my only HF radio is my 706
[11:02] <juxta> which lives in the car when I'm chasing balloons ;p
[11:02] <Laurenceb_> http://arduino.cc/blog/2010/09/24/dinner-is-ready/
[11:02] <Laurenceb_> im actually impressed
[11:03] <Laurenceb_> the ethernbet and usb support sounds very nicely put together
[11:03] <m1x10> http://imagebin.org/116082
[11:04] <m1x10> I can hear your comments plz :)
[11:05] <juxta> yeah I saw that too Laurenceb, I like the idea of having the USB without the FTDI chip
[11:07] <juxta> looks good m1x10, is that to sit on an arduino?
[11:08] <m1x10> yeah
[11:08] <m1x10> with atmega644
[11:15] <Darkside> i need to do something like that with an ad9835
[11:15] <Darkside> like, a hf transmission shield
[11:15] <Darkside> attach antenna + 12v and go
[11:16] <Darkside> if 40mw proves to be powerful enough, i might go ahead and do it....
[11:17] <juxta> if you only need 40mW, just inbclude a step up
[11:18] <Darkside> nah, the amp draws 50mA at 12v :/
[11:19] <Darkside> its massively inefficient
[11:19] <Darkside> 600mw in for 40mw out
[11:20] <Darkside> i need to design a better preamp... but doing a wideband preamp is difficult
[11:20] <Darkside> the op-amp amplifier i'm using will work up to about 100mhz
[11:20] <juxta> hmm that is a little inefficient, hehe
[11:21] <Darkside> yep
[11:21] <Darkside> gotta reduce my boards current consumption
[11:21] <Darkside> its drawing 200ma at 12v atm
[11:21] <m1x10> Can I use the same antenna for both RADIOS ?
[11:22] <Darkside> i was thinking of using a 11.1v lipo to run it -@that would give me about 35mW rf still
[11:22] <Darkside> then it will just slowly lower output power as the battery discharges
[11:23] <Darkside> and im broadcasting batt voltage, so ill be able to monitor it from the ground
[11:23] <Darkside> if batt voltage drops to a certain point, switch telemetry to domino

[14:18] <Laurenceb_> so does LUFA
[14:19] <Laurenceb_> will probably stick with ft232r for the dongle im designing atm
[14:19] <Laurenceb_> with a micro in there you could do dgps with an attached receiver... but its not really worth the effort

[15:28] <Lunar_Lander> is it running on C?
[15:28] <Lunar_Lander> because I'm just learning C++
[15:29] <Randomskk> the predictor is C but already supports float I think

[15:45] <m1x10> I have an old document (2003)
[15:45] <m1x10> saying
[15:45] <m1x10> Region 1 has SSTV(FM/AFSK) at 433.400
[15:45] <m1x10> is that correct?
[15:45] <m1x10> I mean is there any change to this until today

[16:13] <Lunar_Lander> how are you?
[16:15] <natrium42> great, what about you?
[16:16] <Lunar_Lander> I'm quite ok
[16:16] <Lunar_Lander> only my project is stagnating
[16:30] <Lunar_Lander> yea
[16:30] <Lunar_Lander> natrium42 ? any suggestions what I can do to get my balloon started?
[16:32] <natrium42> keep it simple for first launch
[16:32] <natrium42> enough things that can go wrong already :)
[16:36] <Lunar_Lander> yeah
[16:36] <Lunar_Lander> what shall I do first?
[16:36] <Lunar_Lander> get styrofoam?
[16:37] <natrium42> do you have the electronics?
[16:37] <Lunar_Lander> not yet
[16:37] <Lunar_Lander> I wanted to do it with someone who does it as a job
[16:37] <Lunar_Lander> but he is busy at the moment, and actually it is angering me
[16:42] <Lunar_Lander> University has a electronics workshop

[17:20] <m1x10> lol
[17:20] <Zephyr_Vortex> I decided to call the payload box of my balloon that way
[17:20] <Zephyr_Vortex> as we have West wind in Europe (=Zephyr)
[17:20] <m1x10> die bot die, bring me back the Lunar_manic
[17:20] <Zephyr_Vortex> and Vortices
[17:20] <Zephyr_Vortex> xD
[17:20] <m1x10> :p
[17:21] <Zephyr_Vortex> :)
[17:21] <Zephyr_Vortex> I went to the pharmacy to ask for these rescue blankets
[17:21] <Dan-K2VOL> hi
[17:21] <Zephyr_Vortex> these golden-silver foils
[17:21] <Zephyr_Vortex> they asked me to come back this week
[17:22] <m1x10> u dont need to go there
[17:22] <m1x10> go to camping stuff
[17:22] <m1x10> i bought it at 1euro
[17:22] <Dan-K2VOL> what are you using them for, payload insulation?
[17:22] <Zephyr_Vortex> yeah
[17:23] <Dan-K2VOL> LDB or a latex?
[17:23] <Zephyr_Vortex> styrofoam
[17:23] <Zephyr_Vortex> and wrap it with that foil
[17:23] <Dan-K2VOL> I mean is it a latex balloon flight?
[17:23] <Zephyr_Vortex> oh sorry
[17:23] <Zephyr_Vortex> yeah latex
[17:24] <Dan-K2VOL> honestly in my experience if you're doing it in the daylight you might get quite a bit of heat just by painting it flat black.
[17:24] <Zephyr_Vortex> yeah that is true
[17:25] <Dan-K2VOL> when we flew the long duration ones over the atlantic, the ones we painted black stayed around 30C inside in the daytime, floating in -40C air
[17:25] <Zephyr_Vortex> wait a minute
[17:25] <Zephyr_Vortex> are you one of the Tennessee team`?
[17:26] <Dan-K2VOL> yeah, I was the the leader
[17:26] <Zephyr_Vortex> cool!
[17:26] <Zephyr_Vortex> congrats for flight IV
[17:26] <Dan-K2VOL> :-) thanks
[17:26] <Zephyr_Vortex> that was the almost successful one right?
[17:26] <Zephyr_Vortex> you're welcome :)
[17:26] <Dan-K2VOL> yes, only a few hundred KM from Ireland
[17:26] <Zephyr_Vortex> yeah
[17:26] <Dan-K2VOL> actually, I'm leading a new group to do it again this winter
[17:26] <Zephyr_Vortex> cool
[17:27] <Dan-K2VOL> wiki.whitestarballoon.com
[17:27] <Zephyr_Vortex> do you only have radios or do you do research on it too?
[17:27] <Zephyr_Vortex> ah ok
[17:27] <Dan-K2VOL> We're trying to do research on them, but have no separate science experiements. Our main goal is to better publicly document how to build and utilize small ZP balloons
[17:27] <Zephyr_Vortex> just found the experiments page :)
[17:27] <Zephyr_Vortex> yeah
[17:28] <Zephyr_Vortex> that is a great idea
[17:28] <Dan-K2VOL> what's that
[17:29] <Zephyr_Vortex> ?
[17:29] <Zephyr_Vortex> your idea is great
[17:29] <Dan-K2VOL> We've almost firmed up a satellite radio to augment the HF telemetry
[17:30] <Dan-K2VOL> found a two-way sat data modem for $140US, with service about $15US/month
[17:30] <Zephyr_Vortex> that is cool
[17:30] <Dan-K2VOL> quite - it means we have reliable uplink commanding, and with that, we can use HF to replay missing telemetry data from propagation dropouts
[17:31] <Zephyr_Vortex> yeah
[17:31] <Dan-K2VOL> can't afford to downlink much telemetry via sat
[17:31] <chris_99> what modem / Sat company is that with Dan-K2VOL, that sounds really cheap
[17:31] <Zephyr_Vortex> do you have a termination device onboard?
[17:32] <russss> Dan-K2VOL: have you seen this? http://natrium42.com/projects/spot/
[17:32] <Dan-K2VOL> yes, we will. We're looking at doing an envelope-tip-over
[17:32] <Zephyr_Vortex> !?
[17:32] <Zephyr_Vortex> what's that
[17:33] <Zephyr_Vortex> I only know that cannon that cuts the payload line and rips open the envelope
[17:34] <Dan-K2VOL> we're going to mount the payload right at the bottom of the envelope, and put a standard rope-melter cutdown at the payload. The payload will also be attached via long rope to the TOP of the balloon.
[17:34] <Zephyr_Vortex> ah
[17:35] <Dan-K2VOL> If you cut the bottom rope, the payload pulls the top over upside down
[17:35] <Dan-K2VOL> and all the helium dumps out the vent
[17:35] <Zephyr_Vortex> yeah
[17:37] <Zephyr_Vortex> that's a cool idea
[17:37] <Zephyr_Vortex> how much is a ZP balloon envelope?
[17:38] <Dan-K2VOL> $300 from Global Western
[17:39] <Dan-K2VOL> not cheap :(
[17:41] <Zephyr_Vortex> yea
[17:41] <Zephyr_Vortex> how much He do you need for oneß
[17:42] <Dan-K2VOL> ~1000 cu ft / 26.6 m3
[17:42] <Zephyr_Vortex> oh ok
[17:42] <Dan-K2VOL> one large T-sized tank
[17:42] <Zephyr_Vortex> and it carries?
[17:42] <Dan-K2VOL> 12lb/ 5.6kg
[17:42] <Zephyr_Vortex> ah
[17:42] <Dan-K2VOL> I think that kg is right
[17:42] <Zephyr_Vortex> that is good
[17:42] <Zephyr_Vortex> yeah
[17:44] <m1x10> Zephyr_Vortex plz change to Luna
[17:44] Nick change: Zephyr_Vortex -> Lunar_Lander
[17:44] <m1x10> ^^
[17:46] <Lunar_Lander> yeah Dan-K2VOL as I said I plan to do latex flights
[17:46] <Lunar_Lander> got a chute from Spherachutes
[17:46] <Lunar_Lander> and one balloon from an english retailer

[18:37] <Lunar_Lander> what happened?
[18:37] <SpeedEvil> I keep meaning to setup a gimballed 500mW green laser.
[18:37] <SpeedEvil> Point at ISS, and look at the camera feed.
[18:37] <Randomskk> reckon you could track it fast enough?
[18:38] <Randomskk> fast and accurately enough, that is
[18:38] <SpeedEvil> Lunar_Lander: I have an unreliable connection which dies every day. I normally through scripting catch the modem going down, and say 'don't retrain, stay offline' then bring it up an hour later.
[18:39] <Lunar_Lander> oh :S
[18:39] <SpeedEvil> Unfortunately about 5 days ago, it retrained at 700kbps - which has limited my stable rate to 512K - though I've been synced at 2M since
[18:39] <Lunar_Lander> oh
[18:39] <SpeedEvil> It's not _that_ fast moving.
[18:40] <SpeedEvil> yes, you need more than your standard scope drive.

[18:53] <Lunar_Lander> yeah
[18:53] <Lunar_Lander> but I have to say
[18:53] <Lunar_Lander> the mug was made months ago when everything still was in shape
[18:54] <SpeedEvil> ;)
[18:55] <Lunar_Lander> yeah
[18:55] <Lunar_Lander> it is kind of saddening that the people don't answer
[18:55] <Lunar_Lander> and I am not that independent yet in terms of skills
[18:55] <Lunar_Lander> e.g. I don't know that much of Electronics and I start to learn C++ now
[18:56] <SpeedEvil> Other people have probably developed other interests.
[18:56] <SpeedEvil> Alcoholism, for example.
[18:56] <Lunar_Lander> yeah
[18:57] <DagoRed> Alcohol + programming = fun debugging.
[18:57] <Lunar_Lander> thing is that the electrician I talked about was quite keen in doing th eballoon
[18:57] <Lunar_Lander> xD
[18:57] <Lunar_Lander> *the balloon
[18:57] <Dan-K2VOL> it's pretty tough to get enough people to stay together for an entire balloon project - it's a tremendous amount of work
[18:57] <Lunar_Lander> yeah
[18:57] <DagoRed> Dan-K2VOL: Really
[18:57] <DagoRed> ?
[18:57] <Lunar_Lander> like my dream of having "guest experiments" from all over the world
[18:58] <Lunar_Lander> all the people said "we're interested"
[18:58] <Lunar_Lander> I gave more info
[18:58] <Lunar_Lander> and then the replies trickled in sort of
[18:59] <Dan-K2VOL> sure, a huge amount of logistics to get a payload constructed, launch coordinated, listeners organized, recovery attempted
[18:59] <Lunar_Lander> true
[18:59] <Lunar_Lander> actually I begun with this
[18:59] <Lunar_Lander> www.projectvortex.weebly.com
[18:59] <Lunar_Lander> manned, up to like 3-4 km
[19:00] <Lunar_Lander> also never really got off the ground
[19:01] <Lunar_Lander> though it could have its advantage as a city air pollution scanner
[19:01] <Lunar_Lander> of some sort
[19:01] <Dan-K2VOL> isn't that the same height as a normal gas balloon flight?
[19:01] <Lunar_Lander> yes
[19:02] <Lunar_Lander> recently I had the idea to use the stratospheric payload with its microcontroller and recorder and use that as some kind of "Data Core"
[19:02] <Lunar_Lander> and then you'd just plug in external experiments
[19:02] <Lunar_Lander> and it would record the data
[19:06] <Lunar_Lander> what do you think?

[19:42] <Lunar_Lander> yeah, in the big balloon
[19:42] <Lunar_Lander> helium in the strato one
[19:42] <fsphil> g'day m1x10 et all
[19:42] <m1x10> what is the big balloon?
[19:43] <Lunar_Lander> the manned balloon I talked about above
[19:43] <m1x10> fsphil I was examining the SSTV thing today
[19:43] <m1x10> manned?
[19:43] <Lunar_Lander> www.projectvortex.weebly.com
[19:43] <m1x10> lol
[19:43] <fsphil> sstv is cool
[19:43] <m1x10> fsphil I make my pcb to support a TTL UARt JPEG cam
[19:44] <m1x10> so i was examining how the hell to make my arduino do it
[19:44] <m1x10> I found that in order to transmit image i should use the 433.400 freq
[19:45] <m1x10> from the bandplan
[19:45] <fsphil> It's unlikely you'll be able to decode the jpeg with the arduino, does the camera support raw / uncompressed images?
[19:45] <m1x10> I also found the sstvx program but later I figured out that was for linux !
[19:46] <m1x10> the cam accepts protocol command to change image resolution and compression rate
[19:46] <fsphil> got a datasheet handy?
[19:47] <m1x10> and returns the jpeg bytes as chunks of 512 each
[19:47] <m1x10> wait
[19:47] <fsphil> there isn't enough memory in an avr to decode the jpeg into something you can use for sstv though
[19:48] <m1x10> http://mixio.herobo.com/LinkSpriteJPEGColorCamera.pdf
[19:50] <fsphil> seems to only produce jpeg data -- could be a problem
[19:51] <m1x10> if I downlink directly the outcoming jpeg bytes, is that bad?
[19:51] <m1x10> yeah, what else it should produce?
[19:51] alikins__ (~alikins@nat/redhat/x-nuzdvhllvznkzmxv) left irc: Quit: Leaving
[19:52] <fsphil> for sstv you'd ideally want an uncompressed image, basically each pixel in order, left to right, top to bottom
[19:53] <fsphil> and the speed from the camera must be controlled so that it is *just* faster than the sstv being sent
[19:53] <m1x10> a 0% compression rate command might do that
[19:53] <fsphil> jpeg doesn't store images like that, it converts them to little blocks of frequency
[19:54] <fsphil> each block is 16x16
[19:54] <SpeedEvil> Or 8*8
[19:54] <fsphil> yes
[19:54] <m1x10> can u explain the "little blocks of frequency"
[19:54] <m1x10> ?
[19:54] <fsphil> hmm
[19:55] <m1x10> i can understand pixels, resolution, pixel size
[19:55] <m1x10> dont know many
[19:55] <SpeedEvil> m1x10: http://www.fileformat.info/mirror/egff/ch09_06.htm
[19:55] <fsphil> http://en.wikipedia.org/wiki/File:Dctjpeg.png
[19:55] <SpeedEvil> jpeg is quite coplex
[19:56] <fsphil> you can send the jpeg directly, but if you lose any bits the image will be corrupt - as I learned quite recently :)
[19:56] <m1x10> I think tomorrow ill spend the day studing the jpeg
[19:57] <m1x10> fsphil, if i loose a bit in the middle
[19:57] <m1x10> the rest image is going to die?
[19:57] <fsphil> the rest of the image is gone
[19:57] <fsphil> yea
[19:57] <m1x10> so i will see half image only?
[19:57] <m1x10> thats bad
[19:58] <fsphil> http://www.flickr.com/photos/fsphil/4526373286/in/set-72157623870036944/
[19:58] <fsphil> yep :)
[19:58] <m1x10> yes i know those pics :)
[19:58] <fsphil> those where jpegs sent over rtty
[19:58] <m1x10> Error correction is possible?
[19:59] <fsphil> that's what I'm working on now
[19:59] <m1x10> do u think its possible?
[19:59] <m1x10> i wanna help
[19:59] <m1x10> if i can for sure
[20:00] <m1x10> but if i send the bytes directly? no sstv no rtty, just AFSK and on air..
[20:01] <fsphil> afsk is what aprs uses?
[20:01] <m1x10> yeah
[20:01] <m1x10> audio freq
[20:02] <m1x10> 1200/2200
[20:02] <fsphil> what baud rate?
[20:02] <m1x10> 1200
[20:02] <fsphil> that's pretty good, at 300 baud it takes about 4 minutes to send a small image
[20:02] <m1x10> so 1 min for m
[20:02] <m1x10> e
[20:03] <m1x10> but is it going to work?
[20:03] <fsphil> what are you using to receive it?
[20:03] <m1x10> nothing
[20:03] <m1x10> lol
[20:03] <m1x10> for the aprs i have ordered the radioshield from argentdata
[20:03] <m1x10> which decodes ax25 frames
[20:04] <m1x10> but for the sstv
[20:04] <m1x10> dont know
[20:04] <fsphil> can you can send any data over this?
[20:04] <m1x10> yes
[20:04] <m1x10> its tx/rx
[20:04] <m1x10> but i need it only for receive
[20:05] <m1x10> I think I should mail that guy to make me a custom radioshield which will not return ax25 frames but the raw data coming out of the afsk demodulation
[20:06] <m1x10> is then possible that I recreate the image?
[20:07] <fsphil> I'll get back to you on that bit, will be testing the new jpeg code later this week hopefully
[20:07] <fsphil> you'd still get gaps in the image where a packet is lost, but it should still decode the rest
[20:07] <m1x10> ok.....
[20:08] <m1x10> there is a pink gay UFO on your images

[20:09] <Lunar_Lander> well I got a lesbian friend
[20:09] <m1x10> pink=gay(if there is man inside)
[20:09] <Lunar_Lander> she is fighting against saying gay
[20:09] <Lunar_Lander> kinda
[20:09] <fsphil> pink used to be a boys colour, back in olden times
[20:09] <m1x10> lesbians are ugly
[20:09] <Lunar_Lander> besides, homosexuality was a high honour in Ancient Greece!
[20:09] <fsphil> um
[20:09] <m1x10> HAHAHAHA
[20:10] <fsphil> way off-topic
[20:10] <m1x10> just having some fun fsphil !
[20:10] <m1x10> Lunar_Lander thats what you learn at school about ancient grece?
[20:10] <Lunar_Lander> xD
[20:11] <Lunar_Lander> well we learned about that Alexander guy and how the Hoplites fought him
[20:11] <Lunar_Lander> and the two "worlds" of Athens and Sparta
[20:11] <W0OTM> howdy
[20:11] <m1x10> hmm
[20:11] <m1x10> interesting things
[20:11] <Lunar_Lander> yeah
[20:11] <Lunar_Lander> we actually
[20:11] <Lunar_Lander> wait
[20:11] <Lunar_Lander> let my try to capture that xD
[20:11] <m1x10> classical enemies was athens with sparta
[20:12] <m1x10> but under the persian pressure the allied and helped each other
[20:12] <Lunar_Lander> yeah
[20:12] <m1x10> I dont get that Hoplites things
[20:13] <Lunar_Lander> yeah the soldiers
[20:13] <m1x10> OPLITHS in greek means a soldier
[20:13] <Lunar_Lander> yeah
[20:13] <Lunar_Lander> Hoplon or so
[20:13] <m1x10> what do u mean they fought them ?
[20:13] <Lunar_Lander> http://en.wikipedia.org/wiki/Hoplite
[20:13] <Lunar_Lander> weren't they the army against the persians?
[20:13] <m1x10> yeah
[20:14] <Lunar_Lander> that's what I meant
[20:14] <Lunar_Lander> they fought Alexander
[20:14] <Lunar_Lander> xD
[20:14] <m1x10> greek hoplites fought alexander? why?
[20:14] <m1x10> rape him?

[20:16] <Lunar_Lander> yeah actually the one guy drew the German Eagle on his shield
[20:16] <m1x10> lol
[20:17] <Lunar_Lander> xD
[20:17] <m1x10> spartans used to draw animals to
[20:17] <m1x10> too
[20:17] <m1x10> or the Lambda letter
[20:17] <m1x10> which meant Lakedaimonius
[20:18] <Lunar_Lander> yeah
[20:18] <m1x10> which means the deamons who dont speak much
[20:18] <Lunar_Lander> cool
[20:18] <m1x10> bah
[20:18] <m1x10> they were crazy
[20:18] <m1x10> ..
[20:18] <m1x10> but helped greece on very bad days
[20:19] <Lunar_Lander> true
[20:19] <Lunar_Lander> and then that guy ran from Marathon to Olympia
[20:20] <Lunar_Lander> or was it from marathon to Athens
[20:20] <m1x10> im not sure
[20:21] <Lunar_Lander> yea
[20:23] <Lunar_Lander> anyway
[20:23] <Lunar_Lander> predictor runs
[20:23] <Lunar_Lander> September 30 flight from Iraklio, Crete
[20:23] <m1x10> lol
[20:23] <m1x10> who is flying from ther?
[20:24] <Lunar_Lander> I just wanted to see what happens in that case xD
[20:24] <m1x10> oh :p
[20:24] <Lunar_Lander> I thought of a manned flight from there to Athens
[20:24] <Lunar_Lander> yeah right, Sep 30 is not possible
[20:24] <Lunar_Lander> it goes right east xD
[20:24] <m1x10> who is going to be the balloon?
[20:25] <m1x10> you say manned...
[20:25] <m1x10> or im not getting something
[20:25] <m1x10> ?
[20:25] <Lunar_Lander> yea, me and a balloon pilot who lives nearby and maybe another scientist or so
[20:25] <Lunar_Lander> in the balloon's basked
[20:25] <m1x10> wtf?
[20:25] <Lunar_Lander> *basket
[20:25] <m1x10> aaaaaa
[20:25] <m1x10> you mean those big balloons
[20:25] <m1x10> lol
[20:25] <Lunar_Lander> yeah like in the race :D
[20:26] <m1x10> i thought those we do for hab
[20:26] <m1x10> lol
[20:26] <Lunar_Lander> so I put in the data for the HAb in also
[20:26] <Lunar_Lander> it would also go east
[20:26] <fsphil> launches from here are currently going north .. into the atlantic :/
[20:26] <Lunar_Lander> and splash down east of Nisos Karpathos
[20:26] <m1x10> i cant help you with athens or crete, but if you loose your way somewhere inside macedonia I might help you.
[20:27] <Lunar_Lander> yeah )
[20:27] <Lunar_Lander> maybe Greek Army can help with one of these Russian Hovercrafts :)
[20:27] <m1x10> pfff
[20:27] <m1x10> Army
[20:27] <m1x10> dont say that

[20:28] <m1x10> if there is someone u know there
[20:28] <m1x10> can get it
[20:28] <Lunar_Lander> hey actually someone from the suburbs of Belfast wrote me up
[20:28] <fsphil> hehe nah, only people I know are in Edinburgh
[20:29] <Lunar_Lander> he runs a party balloon business
[20:29] <Lunar_Lander> and he asked if I could help him make a HAB
[20:29] <fsphil> oooh
[20:30] <fsphil> what was he hoping to launch?
[20:31] Simon-MPFH (~simon@phantom.mpfh.co.uk) left irc: Quit: Leaving
[20:31] <Lunar_Lander> first he wanted to know if you can predict the course
[20:31] <Lunar_Lander> I showed him the website
[20:31] <Lunar_Lander> then he wanted to make a HAB with some basic instruments
[20:31] <Lunar_Lander> and he wanted to fly a party balloon on it, to see when it pops
[20:32] <Randomskk> the party balloon idea is quite fun
[20:32] <Randomskk> they will probably pop really quite soon though
[20:32] <Lunar_Lander> he said
[20:32] jerry507_mac (~jerry507@jsmac.student.iastate.edu) joined #highaltitude.
[20:32] <Randomskk> if you had a pressure guage or a flow rate meter or something you could test at home, just inflate until it pops
[20:32] <Lunar_Lander> "I would put the balloon in some kind of "cage" to preserve the shreds"
[20:32] <Lunar_Lander> yea
[20:32] <Randomskk> paper mache it :P
[20:32] <fsphil> lol
[20:32] <Lunar_Lander> xD
[20:33] <Lunar_Lander> btw now that I got one of these Hong Kong spycams from the dutch flight
[20:33] <Lunar_Lander> I read that the casings of that were tested to contain 1500+ ppm of lead
[20:35] <m1x10> Lunar_Lander what Hong Kong spycams ?
[20:36] <Randomskk> suggest don't lick them

[20:39] <m1x10> with embedded bat and stoarage
[20:39] <m1x10> for 2 hours it can last
[20:39] <m1x10> i plan to stick it on the cord
[20:39] <m1x10> lokking down the payload
[20:39] <Lunar_Lander> cool!
[20:39] <m1x10> but it might freeze out there :P

[20:48] <m1x10> they have day and night in 1 hour
[20:49] <m1x10> if u wait about an hour you will see daylight again
[20:49] <m1x10> i have it opened all the time
[20:49] <Lunar_Lander> isn't it 45 minutes?
[20:49] <fsphil> it's over the south atlantic now

[20:50] <m1x10> ?
[20:50] <fsphil> http://www.heavens-above.com/#
[20:51] <Lunar_Lander> good question, probably no
[20:51] <fsphil> that's weird, the station is still in daylight
[20:51] <Lunar_Lander> consider the distances between the solar systems
[20:51] <fsphil> but not for long....
[20:51] <Lunar_Lander> yeah because of the altitude
[20:51] <Lunar_Lander> on the way to the moon, you are in constant day xD
[20:52] <Lunar_Lander> DMAN!!!!
[20:52] <m1x10> Lunar_Lander why should they come from the outside?
[20:52] <Lunar_Lander> *DAMN
[20:52] <fsphil> now *that* is a sunset :D

[20:52] <m1x10> it happens fast !
[20:52] <Lunar_Lander> yeah
[20:52] <m1x10> Lunar_Lander why should they come from the outside?
[20:52] <Lunar_Lander> yea I don't know
[20:53] <Lunar_Lander> if they lived here and died, we probably would find fossils or os
[20:53] <Lunar_Lander> *so
[20:53] <m1x10> If earth is about 4.5billion year
[20:53] <m1x10> i think
[20:53] <m1x10> its too much time
[20:53] <m1x10> for may kinds to arrived here
[20:53] <m1x10> many*
[20:54] <m1x10> i cant fit it in may head that humanity was here the last thousands of years

[21:02] <Lunar_Lander> I finally found out what "AVI" is as a country
[21:02] <Lunar_Lander> American Virgin Islands
[21:02] <m1x10> lol
[21:05] <Lunar_Lander> "
[21:05] <Lunar_Lander> So this race would have been most interesting in terms of distances and time had there not been the drama over Belarus.
[21:05] <Lunar_Lander> Three American balloons entered the Belarus territory early in the morning, after having transmitted their position to the Minsk air traffic control.
[21:05] <Lunar_Lander> One of these three was the Virgin Islands team of Alan Fraenkel and John Stuart-Jervis. Alan Fraenkel was an enthusiast balloonist who developed the ‘Windreader’: an instrument allowing to read the direction and speed of the wind on different altitudes very precisely.
[21:05] <Lunar_Lander> Before entering the Belarus territory the Minsk reply was in hardly understandable English; upon entering the territory Minsk first replied in Russian only, later on they did not reply at all.
[21:05] <Lunar_Lander> The teams of Levin & Sullivan and of Wallace & Brielman were forced to land by the military authorities.
[21:05] <Lunar_Lander> A military helicopter approached the ‘D-Caribbean’.
[21:05] <Lunar_Lander> The helicopter tried to contact the ballooning team in Russian, circled around the balloon for nearly half an hour and then opened fire! The balloon and the basket were hit by some 20 bullets. The balloon crashed in a forest and Alan Fraenkel and John Stuart-Jervis were killed.
[21:05] <Lunar_Lander> "
[21:10] <m1x10> thats sad

[21:46] <Lunar_Lander> record is 92

[22:13] <chris_99> ah, thought they where hot air balloons
[22:13] <Lunar_Lander> hot air balloons would burn propane anyway
[22:13] <Lunar_Lander> xD
[22:13] <jcoxon> they either vent helium or drop sand
[22:14] <Lunar_Lander> H2
[22:14] <Lunar_Lander> H2 it is ;)

[22:44] <SpeedEvil> some do
[22:45] <SpeedEvil> The limit is supposed to be cutting out at 60000 feet and 1000 knots.
[22:45] <SpeedEvil> Some do OR
[22:45] <SpeedEvil> And some are just rather broken when you take them above expected heights, as they really don't want to believe they are higher than everest
