[00:01] <W0OTM> its either still up there, or the cold killed the battery
[00:04] <NigeyS> yups, fingers crossed its just out of range, id like to see it come back down.. somewhere
[00:06] <W0OTM> has anyone used a 1/4 watt 10ohm resistor to a 9V batt as a cutdown device?
[00:07] <W0OTM> ITS BACK!
[00:07] <W0OTM> just east of the mississippi
[00:08] <NigeyS> yey
[00:08] <SpeedEvil> :)
[00:09] <SpeedEvil> W0OTM: I've got some resistors specced to 350C surface temp.

[00:09] <W0OTM> TashBag is FALLING
[00:09] <W0OTM> east of the mississippi
[00:09] <SpeedEvil> W0OTM: I have a design using one of those - within ratings as a cutdown.
[00:09] <W0OTM> Time 2011-03-06 18:08:08 : Altitude 4713 ft : Speed 15 mph : Heading 35 °
[00:09] <SpeedEvil> It does take a minute.
[00:13] <griffonbot> @LVL1WhiteStar: Payload in the park: Sat got short reports to mission control, no bulk msgs thru, weretoo cold to wait for em! #arhab http://t.co/JXGkny8 [http://twitter.com/LVL1WhiteStar/status/44551226054021121]
[00:14] <NigeyS> W0OTM, think ya battery has died
[00:15] <W0OTM> dunno, maybe crappy cell coverge
[00:15] <NigeyS> SpeedEvil, how does that work? tie the resistor to the cord ?
[00:15] <SpeedEvil> NigeyS: /o\ - sortof though not so steep
[00:16] <SpeedEvil> the resistor is arranged to lightly press against the cord
[00:16] <NigeyS> ahh i see
[00:17] <NigeyS> meh 2 hours and this lassen still hasnt got a lock
[00:18] <W0OTM> I just tried to call the cellphone, and its out of range
[00:18] <W0OTM> went straight to VM
[00:18] <NigeyS> dam
[00:18] <W0OTM> LOL, Voicemail on a trashballoon
[00:19] <NigeyS> lmao
[00:19] <NigeyS> where did you launch from ?
[00:19] <W0OTM> Ottumwa, IA
[00:19] <NigeyS> its gone pretty far then
[00:21] <Lunar_Lander> ^damn
[00:21] <Lunar_Lander> I forgot the Lassen IQ GPS
[00:22] <NigeyS> get a decent antenna, the patch antenna is absolute rubbish!
[00:22] <Lunar_Lander> yeah but I forgot to order it

[00:23] <NigeyS> lol
[00:23] <Lunar_Lander> do you think that I can dismount the antenna from the Vaisala RS80 and somehow solder it to a wire and connect that to the Lassen?
[00:24] <NigeyS> unlikely
[00:24] <NigeyS> and if ure getting a lassen i hope you can solder smd

[01:57] <natrium42> wb WB8ELK
[01:57] <WB8ELK> Hi all
[01:57] <natrium42> how are you, bill?
[01:58] <WB8ELK> Time for me to get on the high altitude chat room
[01:58] <WB8ELK> I ended up in the #high chatroom for awhile though
[01:58] <natrium42> :)
[01:58] <WB8ELK> probably a drug chatroom I would guess LOL
[01:59] <natrium42> haha, oops
[01:59] <WB8ELK> I'm hooked up remotely to the LVL workspace for the White Star group at the moment
[01:59] <WB8ELK> they are doing some system testing
[01:59] <Dan-K2VOL> we rolled our payload out to the city park
[01:59] <Dan-K2VOL> And let it soak up some satellites
[02:00] <Dan-K2VOL> Got about a dozen position reports through orbcomm :-)
[02:00] <WB8ELK> Hello to W0OTM...boy you sure put in some long miles yesterday on your chase
[02:00] <natrium42> and he launched a trash bag balloon today
[02:01] <WB8ELK> He did...I wasn't aware of it

[02:02] <natrium42> http://www.instamapper.com/ext?key=13662000794391923371
[02:02] <natrium42> some guy found the paylo0ad and called
[02:02] <WB8ELK> how far did it go?
[02:02] <natrium42> he's getting it back tomorrow
[02:04] <WB8ELK> Did the Boost Mobile phone come back alive during yesterday's flight to the Chicago area? I forget to check....it dropped out at 5500 feet on the way up
[02:04] <natrium42> nice improvised launch
[02:04] <WB8ELK> we had 30 knot winds here so a trash bag balloon wouldn't have worked well
[02:05] <natrium42> aah
[02:05] <natrium42> no idea about the phone
[02:05] <WB8ELK> I didn't fly anything this weekend....4 inches of rain and gale force winds all weekend here in Alabama
[02:05] <natrium42> eek, i am visiting cali right now
[02:05] <natrium42> it's much warmer
[02:06] <WB8ELK> The one I flew on 20 meters a week ago was heard in California for an hour or more after landing....he also had some nice Hellscreiber screenshots as well
[02:06] <WB8ELK> I was on 14.102 MHz running DominoEX16 RTTY Hellscreiber and CW
[02:07] <WB8ELK> but the best path from here was to CA....it was hanging in a tree in eastern Georgia at the time
[02:10] <natrium42> oh, wow
[02:11] <Darkside> WB8ELK: how much power?
[02:11] <WB8ELK> a half watt
[02:11] <Darkside> bah :P
[02:11] <Darkside> i guess its still QRP to
[02:12] <Darkside> tho*
[02:12] <WB8ELK> the two I flew in January on 40 meters was heard all over the midwest and CO during flight and both were heard right at landing and well afterwards
[02:12] <WB8ELK> yes QRP for sure
[02:13] <WB8ELK> It's just as good as running a FindMeSpot as long as you have enough ground stations scattered around linked into SpaceNear
[02:13] <WB8ELK> I think I prefer 40 meters ( I was on 7.102 MHz) during the nighttime and 20 meters during the daytime
[02:13] <WB8ELK> but the antenna wire is 66 feet long on 7 MHz
[02:14] <WB8ELK> I used #22 gauge hookup wire so it was only about 4 ounces for the antenna
[02:15] <WB8ELK> when the batteries started to go on the one that landed in the tree in GA on 40 meters...I could hear it via the Colorado GlobalTuners internet radio even when I was sending out about 200 milliwatts

[10:07] <Darkside> morning!
[10:07] <NigeyS> hey Darkside
[10:08] <NigeyS> how much do i hate my isp today ...... LOTS! :@
[10:08] <Darkside> avr programmer?
[10:08] <Darkside> or piccity pic
[10:08] <NigeyS> net provider
[10:08] <Darkside> oh
[10:08] <Darkside> :P
[10:09] <NigeyS> virginmedia have decided they need to dig up the cable running all through the street, and lay new ducting, which means no cable modem from this morning until at least friday! :(
[10:09] <SpeedEvil> Oh noes!
[10:10] Action: SpeedEvil has backup internets.
[10:10] <NigeyS> muppets, some advanced warning would have been nice, only warning i got was the JCB chisseling at the tarmac at 8am! lol
[10:11] <earthshine> I have a Vodafone PAYG dongle for such emergencies
[10:12] <NigeyS> i got this orange dongle.. which is err.. not to good tbh
[10:12] <NigeyS> very rarely get a 3g signal
[10:12] <SpeedEvil> I have a vodaphone dongle.
[10:12] <SpeedEvil> On a 6m pole.
[10:12] <NigeyS> haha seriously ?!
[10:13] <SpeedEvil> Well - I did - '3' SIM gets signal in the house.
[10:13] <SpeedEvil> I just now need to finish sanding down my new ipad SIM, and see if it works properly.
[10:13] <NigeyS> sanding?!
[10:13] <SpeedEvil> (cut SIM out of carrier card with chisel, to match the shape of a normal SIM.
[10:14] <SpeedEvil> Sand to exact shape and size.
[10:14] <NigeyS> oo thats nifty!
[10:14] <SpeedEvil> The ipad contract is 10 gig or so for 15 quid. Much better value than their other offerings.
[10:15] <SpeedEvil> Question is of course will it work outside an ipad.
[10:15] <NigeyS> hmm good question
[10:15] <SpeedEvil> Also - the excess data rates are comedic.
[10:15] <SpeedEvil> Another gig over your allowance is something like 50 quid.
[10:15] <NigeyS> haha same as orange then, in fact extortionate would be the better word!
[10:16] <NigeyS> bloody hell!!!!
[10:21] <fsphil> O2 data sim, you pay £2.50 for a day/200mb -- go over and it just stops
[10:22] <NigeyS> dam, o2 signla here is worse than orange :(
[10:22] <NigeyS> signal*
[10:22] <SpeedEvil> For small volume - get t-mobile PAYG
[10:22] <SpeedEvil> Pay for the 6 month internet booster - which is 20 quid
[10:23] <SpeedEvil> this gets you 500M/mo
[10:23] <SpeedEvil> It used to be 1G/mo - which was great value.
[10:23] <NigeyS> ahhh, i'll try and grab 1 in town while im out
[10:23] <SpeedEvil> It's great for backup connectivity, while being lots better than PAYG rates.
[10:23] <SpeedEvil> Plus - even without it, your data is capped at a quid a day
[10:24] <NigeyS> ah brill that should do nicely

[18:53] <DanielRichman> ok. I'm looking at writing the uplink for ALIEN2. Uplink will probably be in rtty, and the receiver comes with a "data slicer", which, as I understand it, maintains a moving average of the signal and outputs a high 1 or a low 0 (binary data) on a pin depending on whether the frqeuency currently received is above or below that value
[18:53] <DanielRichman> that's connected to a digital IO
[18:53] <DanielRichman> I've also connected the analogue counterpart (i.e., where the frequency received is proportional to the voltage output) to an ADC
[18:54] <DanielRichman> either way I'll have to write a software usart, but would it be worth it using the adc to sample the incoming data, and work out where the rtty is myself?
[18:54] <DanielRichman> or should I just go for a digital usart.
[18:55] <fsphil> digital would probably be fine
[18:56] <Laurenceb> interesting
[18:56] <Laurenceb> so whats the hardware?
[18:56] <DanielRichman> the downside of digital is that in order to make it work, the datasheet specifies that I should probably use some manchester encoding to keep the average-bit in the middle
[18:56] <DanielRichman> hardware is atmel xmega (internal 12 bit adc) with radiometrix NiM2 txrx module
[18:56] <Laurenceb> you are using a radiometrix rx module?
[18:56] <Laurenceb> aha
[18:57] <Laurenceb> how much power on the ground?
[18:57] <DanielRichman> as much as I can get my hands on
[18:57] <Laurenceb> heh

[18:57] <DanielRichman> but the better it performs, the better
[18:57] <Laurenceb> id do the snr calculations then
[18:57] <DanielRichman> it would be awesome if I could do a 33k uplink with 10 watts, but I doubt that
[18:57] <Laurenceb> but software is going to massively outperform ntx2 + hardware
[18:58] <Laurenceb> especially if you can do sdr
[18:58] <fsphil> the way I'd though about doing it, is having an RC filter create an average, and use the digital comparator with the original and averaged signals to produce the binary
[18:58] <Laurenceb> but an xmega might struggle... im not asure
[18:58] <Laurenceb> ive done this in matlab using logged data
[18:58] <fsphil> as long as the uplinked data isn't all zeros or ones, you won't need manchester encoding

[18:58] <Laurenceb> using a frequency locked loop and delay locked loop
[18:58] <DanielRichman> hmm. so, using the adc and sampling each bit many times, and averaging, might perform better?
[18:59] <Laurenceb> and a correlator to find packet headers
[18:59] <Laurenceb> basically yes, thats a delay locked loop
[18:59] <DanielRichman> there's a received-signal-strength-indicator, so I should be able to know when there's a transmission or not
[18:59] <Laurenceb> you might be able to sample the 500khz radiometrix baseband
[19:00] <Laurenceb> xmega has dma so that helps you a lot
[19:00] <fsphil> make sure you have a good sized checksum on the uplinked data
[19:00] <DanielRichman> oh, yes :P
[19:00] <Laurenceb> the bandwidth of the baseband is <<500khz
[19:00] <DanielRichman> Laurenceb: I'm not familiar with anything signal-engineering.
[19:00] <fsphil> I imagine you can do this with 1 watt
[19:00] <Laurenceb> so provided you can get low jitter on the adc sampling you may be able to sample slower
[19:00] <fsphil> unless the nim2 is totally deaf?
[19:00] <Laurenceb> DanielRichman: id be able to help :P
[19:01] <Laurenceb> the noise figure is quite poor
[19:01] <Laurenceb> but theres nothing to stop you sticking an lna on
[19:01] <Laurenceb> of course you could just use a cc1020
[19:01] <DanielRichman> I see
[19:02] <DanielRichman> I believe - just trying to remember somethign I saw on a wiki - when cusf tried an uplink they needed a significant amount of power (?)
[19:02] <Laurenceb> cc1020 AGC responds to 86KHz bandwidth tho
[19:02] <Laurenceb> yes
[19:02] <Laurenceb> i think youll see a lot of stuff on the ground
[19:02] <Laurenceb> so cc1020 might start to suffer from RFI more than radiometrix + lna
[19:03] <Laurenceb> theres probably software hacks to make the cc1020 perform a bit better to out of band rfi - ive only used the recommended settings from the app note
[19:03] <DanielRichman> in a little while I'll have the radiometrix + adc (rssi & rxd) hooked up over usb so should be able to dump some test data
[19:03] <Laurenceb> personally id go with LNA -> radiometrix Rx -> hacked baseband output -> xmega
[19:04] <Laurenceb> for good RFI rejection and low noise performance
[19:04] <DanielRichman> ok. thank you for the tips ;) I'm not sure I'll be able to do all of that due to hardware limitations but iwll try to get close ish
[19:05] <Laurenceb> but i dont have experience of how the radiometrix responds to out of band RFI
[19:05] <fsphil> are you uplinking the data FM modulated, or just RTTY over USB?
[19:05] <Laurenceb> if you have some nice ham hardware on the gnd (like a ssb transmitter) you could use psk
[19:06] <Laurenceb> which would be nice
[19:06] <Laurenceb> pity ssb transmitters for ham dont go very wide
[19:06] <DanielRichman> rtty over usb will probably be the simplest fsphil
[19:07] <fsphil> DanielRichman, was thinking that
[19:07] <Laurenceb> the ultimate for performance would probably be some sort of wideband CDMA type spread spectum
[19:07] <DanielRichman> :O
[19:07] <Laurenceb> but yes, hard to do with fldigi and ham hardware :p
[19:07] <fsphil> yep, but if the simple approach works then why bother? ;-)
[19:08] <Laurenceb> personally id try psk-31 or whatever from fl-digi
[19:08] <Laurenceb> doing psk detection really isnt that hard
[19:09] SpikeUK (56a3eb73@pdpc/supporter/monthlybyte/spikeuk) joined #highaltitude.
[19:09] <Laurenceb> much easier than rtty to do it properly imo
[19:09] <DanielRichman> doing psk would require hacking out an internal signal from the radiometrix (?)
[19:09] <Laurenceb> yes
[19:09] <Laurenceb> its just a test pad
[19:09] <Laurenceb> you can solder to it
[19:10] <DanielRichman> oh, cool
[19:11] <Laurenceb> set the adc up to use dma and sample at... i dont know maybe 200khz
[19:11] <Laurenceb> no, lets say 215khz
[19:12] <DanielRichman> dmaing the results straight into a buffer in ram?
[19:12] <Laurenceb> 500-(2*230)=40khz
[19:13] <Laurenceb> your new carrier baseband is downconverted
[19:13] <Laurenceb> then you grab data from ram and use a costas loop followed by a dll bit slicer
[19:15] <Laurenceb> wikipedia it
[19:15] <dehuman> haha sweet 'costas loop and ddl bit slicer'
[19:15] <dehuman> i think i will google those
[19:16] <DanielRichman> okey :-)

[19:21] <MrCraig> hi jonsowman - hi all
[19:21] <MrCraig> jonsowman: you mentioned that you guys are launching on the 9th too?
[19:21] <Dan-K2VOL> hi
[19:21] <jonsowman> you pinged me the other day and I never got back to you, sorry
[19:21] <jonsowman> MrCraig: yes, probably
[19:22] <MrCraig> no worries :) I was just curious about the filling mechanism for the balloon - I have none as yet, so wondered if it's something you might have already?
[19:22] <jonsowman> yep we have all the filling kit required
[19:24] <MrCraig> great, so I'll just order a cylinder this week and should be all set. I have just about all the payload components, a few minors still to do. The only sticking point now is the software for the flight computer, which I'm working on. Ultimately I have the less than ideal option but I'm working out bugs for a better solution.
[19:25] <jonsowman> fine :)
[19:25] <jonsowman> sounds good

[19:28] <MrCraig> Ordered the camera the other day - it's not the greatest but fits requirement. I wanted an incredibly cheap camera because being my first go at this the risk is higher of loss, and I wanted the highest resolution possible. I've ordered a 12mp for only £30 with the added bonus of a party mode that'll shot every x seconds. The only down side really is that it's a wide angle but that might be a good thing.

[19:46] <SpeedEvil> Highest res is really questionable.
[19:47] <SpeedEvil> The only point really is if you point is trstraight down, and want pics at relatively low altitude.
[19:47] <SpeedEvil> Well - at least in the UK.
[19:47] <SpeedEvil> The air never gets clear enough for more than 320*240 to be usable.
[19:47] <SpeedEvil> Well - maybe a little more. :)
[19:48] <SpeedEvil> But look at some of the pictures - 12MP is essentially never useful at altitude.
[19:48] <SpeedEvil> (pointed sideways at least)
[19:49] <Dan-K2VOL> SpeedEvil - you're saying the air never gets clear enough at what altiude
[19:49] <MrCraig> hmm - perhaps aiming for 12MP was excessive, but I just figured to aim for the highest I could get. Because it spits them to jpeg there's plenty of memory for as much as one every 15 seconds.
[19:50] <MrCraig> higher resolution can mean more grainy at low altitude I'm sure, but at higher altitudes I don't think that'll be such a limitation.
[19:50] <SpeedEvil> Dan-K2VOL: at near the top
[19:51] <W0OTM> Mission Recap:
[19:51] <W0OTM> First, we are thankful for everyone who participated in the iHAB-3 launch. What a GREAT way to spend a chilly winter day!
[19:51] <W0OTM> iHAB-3 was a floater, staying aloft for 6 Hours - 26min, reaching a burst altitide of 79,102ft and traveling 234 miles down range. We received signal reports of the 20 beacon from accross the United States and Canada. Many operators from Iowa, Illinois and Wisconsin had the opportuinity to make contacts via the VHF simplex repeater.
[19:51] <SpeedEvil> It basically completelyblurs out.
[19:51] <W0OTM> Both misson goals were completed, and post flight analysis continues in preparation for iHAB-4 before Spring 2011.
[19:51] <SpeedEvil> W00!

[19:55] <Dan-K2VOL> SpeedEvil - that's interesting, we never had more than about 3MP so I'm not sure, but it seemed to be clearer the higher we went on the UTARC UX flights
[19:56] <Dan-K2VOL> you'd get to see detailed cloud formations anyway
[19:56] <MrCraig> SpeedEvil: would you agree though, that for the purposes of printing the images, a higher resolution will allow for larger prints?
[19:56] <Dan-K2VOL> would be interesting to do a stabilized night flight cam
[19:56] <SpeedEvil> Well - not really - if ther is no data there, then you don't lose any by upsampling.
[19:57] <SpeedEvil> Also - I've seen some startlingly clear images from other parts of the world.
[19:57] <MrCraig> :-/ oh well, no harm
[19:57] <SpeedEvil> And pointing down will get lots more data

[20:12] <SpeedEvil> Was there a fag on the end?
[20:12] <SpeedEvil> flag
[20:12] <Dan-K2VOL> no
[20:12] <Dan-K2VOL> it just takes advantage of the angular momentum of the pole's mass
[20:13] <Dan-K2VOL> it has to rotate slower when mass is extended farther from the center of rotation
[20:13] <SpeedEvil> yeah
[20:13] Action: SpeedEvil is familiar with angular momentum.
[20:13] Action: SpeedEvil wants to make a fapping craft using it.
[20:13] <SpeedEvil> flapping
[20:14] <SpeedEvil> Using accellerating or decellerating a rotating mass connected to a wing to tilt it.
[20:14] Action: fsphil donates an L key to SpeedEvil
[20:15] <SpeedEvil> I need to hoover my keyboard.
[20:15] <Dan-K2VOL> haha SpeedEvil, I do believe you need to be careful about your misspellings
[20:16] <Dan-K2VOL> Flags and Flaps without Ls over here aren't the cleanest words :-P
[20:16] <SpeedEvil> I tend to type under the blankets, as it's cold in here, and not look at what I'm typing. This can cause issues.
[20:18] <SpeedEvil> Basic idea of the above is simple. -----|----- = a wing, with a weighted stick mounted in the middle, and rotating with its axis along the wing.
[20:19] <SpeedEvil> The centre of mass of the system stays stationary, but the wing is oscillated up and down due to the varying distance between it and the centre of mass.
[20:20] <SpeedEvil> In addition,if you slow and speed up the weighted stick, then you can tilt the wing.
[20:20] <SpeedEvil> = flapping
[20:20] <SpeedEvil> With a rigid wing
[20:20] <SpeedEvil> And one moving part.

[21:39] <rjharrison> http://www.robertharrison.org/images/parachute/
[21:39] <rjharrison> Load up A first
[21:40] <Upu> looking
[21:40] <rjharrison> Right notice the payload string denoted by toy gun
[21:40] <rjharrison> This is the main line to the balloon
[21:41] <rjharrison> This goes though the chute and out of the center hole
[21:41] <rjharrison> The parachute should be limp like this to allow it to inflate properly on the way down
[21:42] <Upu> loading...
[21:42] <rjharrison> B is quite useless save to show how limp the chutes confluence point is
[21:43] <Upu> loading.. :)
[21:44] <rjharrison> C- Is blured but shows the main line exiting nad beeing ties on to the centre hole with a slip knot to hold the chute in place
[21:45] <rjharrison> The chute should show good structure when pulled rapidly along hoizontally simulating a fall to ground.
[21:45] <Upu> my browser is playing silly buggers let me just download them and look
[21:45] <rjharrison> Too tight and the parachute wont open properly
[21:45] <rjharrison> Too slack the same thing.
[21:46] <rjharrison> Pulling tight and backing off about 10-15 cms slack should do it.
[21:46] <Upu> I dunno if my HDD is on the way out but my PC keeps freezing up
[21:46] <Upu> does not like your pictures :)
[21:47] <Upu> ok
[21:47] <Upu> trying to work this out in my head
[21:48] <Upu> what happens if a big lump of latex is left on the top ?
[21:48] <Upu> I get there is enough slack to open the chute properly
[21:51] <rjharrison> This is the rule of thirds
[21:51] <rjharrison> Pay out 20m of string
[21:51] <rjharrison> attach chute at 2/3 along line
[21:51] <Upu> yep
[21:51] <rjharrison> then ballon at 3/3
[21:52] <Upu> yep
[21:52] <rjharrison> If balloon remins it will fall to 1/2 way between chute and payload
[21:52] <rjharrison> Ie keeping clear of both
[21:52] <Upu> and partially collapse the chute ?
[21:52] <earthshine> evening
[21:52] <Upu> hi
[21:53] <rjharrison> It does upset chute structure a bit in practive makes no real difference
[21:53] <Upu> so the payload line runs right up the center of the chute and through a hole in the top of it
[21:53] <rjharrison> the most imporant thing is to stop the balloon remains strangling the chute. The rule of thirds accomplishes this
[21:54] <Upu> got you
[21:54] <Upu> neither of my chutes have holes :)
[21:55] <Upu> scissors time
[21:56] <fsphil> I tied the parachute to the cord going between the balloon and payload, left it dangling
[21:56] <Upu> 48" x form or 36" round ?
[21:56] <rjharrison> fsphil, that's cool but it will inflate on the way up
[21:56] <fsphil> 24" round
[21:56] <fsphil> rjharrison, it did a bit yea
[21:57] <Upu> no thats my choice
[21:57] <rjharrison> fsphil, sometimes that causes turbulance and spin
[21:58] <fsphil> I think it did - the payload lost it's antenna shortly after launch
[21:58] <rjharrison> Ahh hence the tracker inof

[22:04] <fsphil> otherwise I'll be flying a small kamikaze payload -- just the basics, and see how far I can get it
[22:04] <Upu> I need to make an antenna on the house so I can pick up without going outside

[22:05] <fsphil> current prediction has it a fair bit north: http://habhub.org/predict/#!/uuid=4c4e18201b86a63048a3624b5fbef2abc2bd0d6a
[22:06] <Upu> still we should be able to pick that up easily
[22:06] jkominar (~justin@64.235.97.218) left irc: Quit: It was a perfectly cromulent thing to do.
[22:06] <Upu> as long as you don't launch in a force 10 gale and smash your antenna up
[22:06] <fsphil> the antenna will be just a bit of coax this time, worst it'll do is bend a bit
[22:07] <fsphil> I don't think the weather's to be that good though
[22:07] <Upu> Rob if you get that NOTAM sorted I'm good to go any weekend
[22:07] <Upu> otherwise I might start speaking to Cambridge :)
[22:08] <fsphil> you can launch here if you can get over this weekend ;-)
[22:09] <rjharrison> Upu, I'll keep you informed
[22:09] <Upu> heh might take you up on that :)
[22:09] <Upu> ok afk dog
[22:09] <rjharrison> RIght time for beddy byes ...

[22:19] <mattltm> Very nice :)
[22:20] <Laurenceb> concrete got annihilated
[22:24] <Laurenceb> thats going to go pretty high to say the least
[22:24] <Laurenceb> i dont get how its going to land without damaging the engine

[22:24] <SpeedEvil> ?
[22:25] <Laurenceb> hmm good point

[22:28] <mattltm> Nope....
[22:28] <mattltm> I'll be doing the first part of my 2e0
[22:28] <fsphil> coolies!
[22:28] <mattltm> so won't be able to listen
[22:28] <fsphil> not so coolies!
[22:28] Nick change: ben_home -> ben_apex
[22:29] <mattltm> Which means you must delay :p
[22:29] <fsphil> I'm doing my 2I0 exam the day before
[22:29] <fsphil> sunday may be better
[22:29] <mattltm> Wow! I didn't realise Stig was so big!
[22:29] <LazyLeopard> mattltm: Where're you doing it?

[22:30] <LazyLeopard> Oh right. Been to the club on a regular evening?

[22:30] <Laurenceb> "We'll be launching and recovering the rocket at Spaceport America in New Mexico early this year. We'll cover the event as much as is possible given the remote location. "
[22:30] <mattltm> Nope. Not my local club but I sat my foundation there.
[22:30] <Laurenceb> so its going to get a bit smashed :/
[22:30] <fsphil> Some say, it can reach orbit. All we know is, it makes a lot of noise
[22:30] <LazyLeopard> Right. When was that?
[22:30] <mattltm> November.
[22:30] <LazyLeopard> Ah. OK.
[22:31] <mattltm> Was going to do the 2e0 localy but nowhere is doing it :(
[22:31] <mattltm> So thought I would go back to BDARS. Nice bunch and good tutors :)
[22:31] <Upu> I'm doing my M6 atm
[22:31] <mattltm> Upu: Good luck :)
[22:31] <LazyLeopard> One of the dozen. ;)
[22:32] <fsphil> good luck both of you
[22:32] <Upu> M6UPU doesn't look taken
[22:33] <LazyLeopard> ...though three of them managed to avoid being caught in the photo that appeared in the newsletter. ;)
[22:33] <mattltm> fsphil: Did you tell me that you were doing your 2e0?

[22:34] <fsphil> mattltm, yea .. well 2I0
[22:34] <LazyLeopard> No, in the November BDARS newsletter. (Well, it might have been on the site at one boint, but I don't see it there now.)
[22:35] <mattltm> Are you a member of BDARS?
[22:35] <mattltm> fsphil: When?
[22:36] <fsphil> friday
[22:36] <LazyLeopard> mattltm: Yep.
[22:36] <fsphil> if I get past that, will have to save up and get a nice FT-857D
[22:36] <LazyLeopard> ...though I missed the December and February meetings.
[22:39] <mattltm> LazyLeopard: I was not in the photo as I finished the test in about 7 minutes, sat around for 20 minutes then left. If I had known there was a photo op I would have stayed :)

[22:49] <mattltm> I command you!
[22:49] <fsphil> it's pretty unusual for it to go north
[22:51] <fsphil> weird quirk with the predictor -- it won't predict outside the box if the payload goes north, but works if it goes south

[22:57] <fsphil> not far from that predicted landing spot ;-)
[22:57] <fsphil> man, going over the irish sea, two major cities and landing near the coast -- too risky
[22:57] <SpeedEvil> :)
[22:58] <SpeedEvil> Indeed - that's about 15 miles from me.
[22:58] <SpeedEvil> But no car, so it's a bit more awkward.
[22:58] <SpeedEvil> And yes, you'd be insane to do that.
[22:59] <fsphil> saturday is a bit more sane, although still mildly insane
[23:00] <Lunar_Lander> btw
[23:00] <Lunar_Lander> the red box
[23:00] <Lunar_Lander> what is it for?
[23:00] <mattltm> What about sunday :P
[23:00] <fsphil> Lunar_Lander, it's the area the predictor download wind data for
[23:00] <fsphil> it shouldn't normally be able to predict outside this box
[23:01] <fsphil> mattltm, it's a bonkers flight path :D

[23:43] <MrCraig> Is anyone here familiar with pic assembler? I'm getting some very strange behaviour that might be down to a misunderstanding in bank switching. A memory location that should be a general file register is getting new values when it's not accessed by my code.
[23:44] <MrCraig> I also thought the channel had gone quiet when in fact my irc window stopped scolling :-/ *grumbles*
