[07:52] <fergusnoble> don't know much about yagarto, which arm are you using?

[07:54] <eroomde> what fpga are you using?
[07:55] <fergusnoble> yeah I think its similar to the flossjtag I'm using
[07:55] <fergusnoble> I think you have to kextunload the driver every time you plug it in :(

[12:03] <costyn> joph: there are cheap ones, but for receiving data from an NTX2 there aren't any cheap ones afaik; cheapest I've found is the FUNcube dongle pro
[12:03] <hibby> costyn: it's not difficult, really - just a voltage regulator and 1 or 2 capacitors. Regardless, it's worth looking into an Arduino Uno for a good starting point in programming it :)
[12:03] <hibby> joph: we usually recommend old radios from yaesu or icom

[13:56] <SamSilver> don't get a yatch
[13:56] <BrainDamage> skydiving is expensive? is it the chute or the lift?
[13:57] <SamSilver> it is a hole in the ocean that you have to keep pouring money into to keep it going
[13:57] <BrainDamage> at least you don't have to pay to keep it afloat
[13:57] <costyn> BrainDamage: the chute and gear mostly; the lift isn't that expensive around 20 euro's a jump
[13:59] <SamSilver> BrainDamage: getting hull cleaned, berth, maintence
[14:04] <hibby> there we go
[14:04] <hibby> aprs at last
[14:05] <fsphil> at least you've got some aprs activity there :)
[14:06] <hibby> Aye, one guy in a car 40 miles away
[14:07] <fsphil> aprsmap is looking really nifty now
[14:07] <hibby> I've not prodded it in a while
[14:07] <hibby> does a nice job though
[14:08] <fsphil> indeedy... and doesn't burn my eyes out like the alternative
[14:08] <hibby> hahah
[14:09] <hibby> it's only good for RX, though
[14:46] <Laurenceb> https://github.com/willdonnelly/pirate-swd
[14:46] <Laurenceb> nice
[14:46] <Laurenceb> now if someone could write a front end gui
[14:49] <Zuph> Sweet
[14:50] <Laurenceb> its not openOCD
[14:50] <Laurenceb> dunno how you interface that with debugger
[14:53] <Zuph> Looks like it doesn't include debugger interface.
[14:53] <Laurenceb> yeah
[14:54] <Zuph> Be easier to use the st-link software with the SWD on the F4 discovery kit.
[14:54] <Zuph> It interfaces with GDB
[14:55] <Laurenceb> yeah
[14:56] <Laurenceb> but is the stm32f1 firmware open?
[14:56] <Laurenceb> for the usb<->SWD bridge
[14:57] <Zuph> What do you mean?
[14:57] <Zuph> Programming the f1, or using the F1-Discovery as programmer?
[14:57] <Laurenceb> downs st-link have a seperate stm32f103 on there
[14:57] <Laurenceb> doesnt
[14:58] <Zuph> Ah, yeah.
[14:58] <Zuph> I was talking about this software https://github.com/texane/stlink
[14:59] <Zuph> They reverse engineered the interface for the ST-Link on the F4 and F1 discovery, so now it's a generic SWD interface.
[14:59] <Zuph> Or, rather, has identical functionality as the windows SWD software.
[15:00] <Laurenceb> but st-link uses prorietory firmware
[15:00] <Zuph> Yeah.
[15:00] <Laurenceb> but its cheap so who cares
[15:00] <Laurenceb> apart from RMS
[15:00] <Zuph> heh
[15:00] <Zuph> Exactly. If you're that ideologically pure, you shouldn't be doing embedded development :-p
[15:01] <eroomde> says me who spent 5 hours yesterday trying to replce D2xx drivers with libftdi
[15:02] <Zuph> lol
[15:02] <Laurenceb> stlink has got to be pretty fast
[15:02] <Laurenceb> probably faster than anything ftdi stuff XD
[15:02] <Laurenceb> *based
[15:02] <eroomde> don't doubt it
[15:03] <eroomde> when firmware starts to become 128kb+ then flash/terst/fix/flash cycles can get a bit annoying
[15:03] <Zuph> I don't know, ST implemented ST-Link v1 as a mangled SCSI driver
[15:03] <Laurenceb> the hell
[15:03] <Laurenceb> crazy
[15:03] <Zuph> My laptop takes like 3 minutes to go through all the USB error checking because it's so confused, before it finally recognizes the device properly.
[15:06] <Zuph> As an aside, I bought a Stellaris dev board the other day. I've been really happy with the ease of getting the thing up and running.
[15:06] <Zuph> TI ships a nice, open source (but not free software, a la rms) bootloader with a bunch of drivers and examples.
[15:08] <Zuph> This board: teholabs.com/products/procyon.html
[15:09] <Zuph> 16 MB of RAM on an external chip
[15:09] <eroomde> gosh
[15:09] <Laurenceb> oh thats Ti?
[15:09] <eroomde> what are you working on Zuph?
[15:09] <Laurenceb> i thought it was NXP for some reason
[15:09] <Laurenceb> mahaha my free samples have shipped from linear
[15:10] <Laurenceb> just ordered about £30 worth of free stuff XD
[15:10] <Laurenceb> their samples policy is awesome
[15:11] <Zuph> eroomde: It was actually a gift. Just making it blink, now.
[15:12] <Zuph> Although the chip they use is definitely suited to some more terrestrial project ideas I have kicking around.
[15:12] <Zuph> Trying to think of something neat to do with all that RAM on the dev board.
[15:12] <zyp> store porn on it!
[15:13] <Zuph> hah
[15:13] <eroomde> v high rate data logging
[15:13] <eroomde> for monitoring some interesting event
[15:13] <Laurenceb> in porn
[15:13] <Zuph> As an aside, the guy that runs Teho Labs is awesome. I had a problem that ended up being my fault. He responded to me within an hour, and followed up a week later to make sure everything was still okay.
[15:14] <eroomde> write it to a buffer then save to SD
[15:15] <Zuph> Now I need an interesting event :-p

[15:29] <costyn> guys: question about antenna's and coax: there's an old discone antenna sitting up on my roof left by a previous owner of the house. The antenna's still connected to a piece of coax, but the coax has been cut and is just lying on the roof. Would it be better to put new coax onto the antenna, or shoudl I connect the new coax to the old; this would save me some work, but might not give great results;
[15:31] danielsaul (~danielsau@99.198.122.28) left irc: Ping timeout: 240 seconds
[15:34] <fsphil> I'd use new coax
[15:34] <LazyLeopard> costyn: How long's the bare end of the coax been exposed to the elements...
[15:34] <costyn> LazyLeopard: no idea, several years at least
[15:35] <LazyLeopard> Save yourself no end of trouble, and use new coax, then. ;)
[15:35] <costyn> hehe ok... that's clear. :) how does one usually connect coax to antenna's? Maybe I should take it down for an inspection actually
[15:36] <costyn> figure out how it works, connect everything up, when it works put it back including new cabling
[15:36] <LazyLeopard> Humidity gets in, and the coax properties go to pot.
[15:36] <costyn> LazyLeopard: ok, good to know
[15:37] <LazyLeopard> If it's a 27MHz CB antenna there's probably a SO-239/PL-259 pair involved.

[16:48] <hibby> swear, mutter, grumble, complain
[16:48] Action: hibby remains in petulent child mode
[16:48] <joph> for directional use you should have a look at a helical antenna
[16:49] <hibby> *axial mode helix
[16:49] <Zuph> *shudder* helix
[16:49] <fsphil> haha
[16:49] <hibby> normal mode axials aren't so useful for directional applications
[16:49] <joph> very hard to calculate :D
[16:50] <hibby> joph: nah
[16:50] <hibby> they're piss easy
[16:50] <joph> we're talking about the same?

[16:58] <hibby> Zuph: my last one was plumbing pipe and thin wire. it worked well
[16:59] <Zuph> Ours was normal mode, 2M band. You've seen it.

[17:00] <TimZaman> buon giorno
[17:02] <hibby> it was amazing
[17:06] <TimZaman> news on hab front?
[17:08] <fsphil> no scandal at the moment
[17:09] <hibby> well, 2m and 70cm are totally silent in the glasgow area
[17:09] <hibby> at rush hour
[17:09] <TimZaman> well in delft i have never ever heared anyone on the 70cm band
[17:10] <TimZaman> Oh yeah, two taxi drivers.
[17:10] <fsphil> there's a repeater on 70cm near me -- I can activate it with 500mw, but nobody uses it sadly
[17:10] <hibby> pretty sad
[17:10] <TimZaman> Very
[17:10] <TimZaman> so phil
[17:10] <TimZaman> no ssdv updates?
[17:11] <fsphil> working on ssdv again soon, once habhound sorta works
[17:11] <fsphil> which is sorta does now
[17:12] Nick change: SamSilver -> SamSilver_
[17:13] <fsphil> want to add an option for better quality image - you may have noticed it can be a bit blocky
[17:13] <hibby> fsphil: how suited is ssdv for h eff?
[17:14] <fsphil> it should work as well as sstv hibby -- and likely better than easypal
[17:14] <hibby> I need to try some with you when I'm back int'shire
[17:14] <hibby> I'll try and make an android port :p
[17:15] <TimZaman> fsphil: oh yeah indeed
[17:15] <hibby> If we could have more decent quality mobile radio apps
[17:15] <hibby> life would be good.
[17:15] <fsphil> yep yep - I tried one test with mattltm, but conditions where a bit naff and nothing was decoded
[17:15] <TimZaman> the only thing i miss in ssdv is that the quality doesnt do anything really
[17:15] <fsphil> yea, the quantisation table is fixed
[17:15] <hibby> fsphil: surely from the Ayrshire coast I should be able to hit you on 10m?
[17:15] <hibby> maybe 6m
[17:15] <fsphil> there's a good chance hibby
[17:16] <fsphil> though I've never tried
[17:16] <hibby> I've heard GB3NI (I think) on my handy
[17:16] <fsphil> I don't hear anything on 6m here
[17:16] <fsphil> ah yea, it's near belfast. I can hear it but can't open it
[17:16] <fsphil> not from the colinear nayway
[17:16] <hibby> 6m on 10W might do the job

[17:25] <TimZaman> costyn: yeah dont worry, we launch a bit after 1400 i guess
[17:26] <TimZaman> so itd be great if you can be at the TU Delft area around 1230-1300
[17:26] <TimZaman> then we set up base
[17:26] <TimZaman> take your radio :)
[17:26] <costyn> TimZaman: well I don't have a radio yet... my ham friend is busy and I haven't been able to get it yet :(

[17:33] <TimZaman> costyn, who are you btw, generally
[17:33] <TimZaman> i mean i know you from here
[17:34] <costyn> TimZaman: dunno man.. what do you wanna know? :)
[17:34] <TimZaman> Can i see your resume?
[17:34] <TimZaman> haha jk
[17:34] <costyn> hehe
[17:34] <TimZaman> are you 12? 20? 60?
[17:35] <costyn> TimZaman: I'm 33, work as a network engineer at quanza.net. Have a wife and a kid and another on the way
[17:35] <TimZaman> Congratulations, that sounds good.
[17:36] <costyn> thx
[17:36] <TimZaman> oh yeah thats actually what i wanted to ask
[17:36] <TimZaman> where do you live
[17:36] <costyn> Rijswijk
[17:36] <TimZaman> !!!
[17:36] <costyn> close to the old center
[17:37] <TimZaman> I lived there once
[17:37] <TimZaman> 6 years ago
[17:37] <TimZaman> the old center is nice, the rest, i'm not so sure :)
[17:37] <costyn> hehe same
[17:38] <TimZaman> Well, to give you an idea of where it is:
[17:38] <TimZaman> http://maps.google.nl/maps?saddr=51.989875,4.376754&hl=nl&ll=51.990476,4.378631&spn=0.005384,0.011512&sll=51.990476,4.378631&sspn=0.005384,0.011512&vpsrc=0&mra=mift&mrsp=0&sz=17&t=h&z=17
[17:38] <TimZaman> For now, there, but we might be tracking it straight from the balcony of the big Aula
[17:39] <costyn> ok cool
[17:39] <TimZaman> Hahah we're in for some crap
[17:39] <TimZaman> i just ran the new prediction:
[17:39] <TimZaman> It will land in Schiedam!
[17:39] <TimZaman> It will go to zoetemeer, then back over delft to maassluis, then to schiedam, haha.
[17:39] <costyn> interesting
[17:40] <TimZaman> That truly sucks, since its comming overhead; we'd have to choose a direction to track it
[17:40] <costyn> well at least we won't have to drive to Heereveen :)
[17:40] <TimZaman> :)
[17:42] <costyn> TimZaman: sent you a linkedin invite
[17:43] <TimZaman> already accepted it
[17:43] <TimZaman> Ah you know your way around computers
[17:43] <TimZaman> thats half the battle

[17:44] <TimZaman> but when we release the balloon, you could be back at base already checking if everything at base works
[17:44] <costyn> ok
[17:45] <TimZaman> last time, we released it, then had to drive the car and run up 14 flights
[17:45] <TimZaman> And before we sat down and had things running it was 20 minutes later
[17:45] <TimZaman> Mostly though, because i connected the radio-audio-output to my computers audiio-output, instead of the audio-input
[17:46] <costyn> hehehe
[17:46] <TimZaman> It occured to us, that every time i said something, the "signal" would light up on the computer - because it had automatically selected the built in microphone :) -
[17:46] <TimZaman> After that it was a breeze
[17:46] Action: costyn afk for a bit... gotta put the kid to bed
[17:46] <TimZaman> Just a sec
[17:47] <TimZaman> im leaving too
[17:47] <costyn> k
[17:47] <TimZaman> but try to ask radiofriends, if you have any
[17:47] <TimZaman> if they can help!
[17:47] <TimZaman> im off!
[17:47] <fsphil> Your launching on a Monday?

[17:48] <TimZaman> i'll give you a call when i fry your server.
[17:48] <fsphil> depends on what's broke in the office :)
[17:48] <fsphil> I might actually take the day off

[17:48] <TimZaman> !!!!!!
[17:48] <TimZaman> that'd be speldid
[17:48] <TimZaman> i'll try to get the word out on the duch radio HAM fora's
[17:48] <fsphil> I've got holidays left, have to take them before christmas
[17:50] <TimZaman> Well, next monday sounds like an excellent day to take off
[17:50] <TimZaman> Long weekend
[17:50] <TimZaman> HAB
[17:50] <TimZaman> Memory leaks
[17:50] <fsphil> if I get my way I may be launching sunday
[17:50] <TimZaman> rly?
[17:50] <TimZaman> ssdv?
[17:50] <fsphil> yea
[17:50] <fsphil> though it's a very long shot at the moment
[17:50] <costyn> fsphil: did you get your notam finally?
[17:50] <fsphil> costyn, nope :) but I'm asking for a one-day one in a hurry ;)
[17:50] <fsphil> hence the long shot
[17:51] <costyn> fsphil: ok :)
[17:51] <fsphil> must run the predictor again
[17:51] <TimZaman> notams are bs
[17:51] <costyn> TimZaman: we'll exchange phone numbers by email and I'll give you a call monday morning
[17:52] <TimZaman> oh sure
[17:52] <TimZaman> ill send you some emails before that time surely
[17:52] <TimZaman> it's really cool you can help!

[18:48] <nosebleedKT> ultra awesome. SMD are really tiny !
[18:48] <Lunar_Lander> yeah :)! cool to hear that :P
[18:48] <LazyLeopard> Don't sneeze while you're soldering...
[18:48] <Lunar_Lander> did the envelope hold up?

[19:10] <Lunar_Lander> yeah

[19:11] <Lunar_Lander> but it was crappy to count the 50 parts
[19:11] <Lunar_Lander> :P
[19:11] <Lunar_Lander> I always counted 2, 4, 6, 8
[19:11] <Lunar_Lander> and then my fingers slipped and I had to start over
[19:12] <nosebleedKT> hahahaha
[19:12] <nosebleedKT> yeah
[19:12] <nosebleedKT> i still look at the resistor and i cant believe how small they are
[19:13] <Lunar_Lander> yeah
[19:14] <Lunar_Lander> :P I kept the bags with the stickers for the capacitors
[19:14] <fsphil-laptop> don't sneeze, you'll loose them all
[19:14] <Lunar_Lander> as they are not labelled

[19:14] <BrainDamage> I use duct tape to prevent smd stuff to fly around when it's outside bags
[19:14] <Lunar_Lander> hi TimZaman
[19:14] <TimZaman> Philip are you here
[19:14] <TimZaman> hi Lunar
[19:15] <fsphil-laptop> I am
[19:15] <Lunar_Lander> how are you?
[19:15] <TimZaman> fsphil im reading some stuff about the FTDI chip.. and why it stops at 70%
[19:15] <TimZaman> might be something to do with suspending it too early
[19:15] <TimZaman> might be because i leave the RX floating?
[19:16] <fsphil-laptop> that's possible
[19:16] <fsphil-laptop> or the rts or dts pins
[19:16] <fsphil-laptop> dtr or whatever that other pin is
[19:17] <TimZaman> this is about buffer overrun, posted by FTDICHIP themselves "Although the hardware does not have RTS/CTS pins the driver does not know this, but it is now forced to monitor certain status bits, which allows the TXE# pin to be kept at logic 1 until space is made available."
[19:17] <TimZaman> but i am sure i have tried this by setting several settings..
[19:18] <TimZaman> Eventually what worked is this: in the crontab, i put something like "@reboot cat /dev/FTDI > &2"
[19:18] <TimZaman> That seems to keep the line open or something, and then it works.
[19:19] <fsphil-laptop> that's reading back from the port, that must keep it active
[19:19] <TimZaman> Though there is one problem, if i know try to send something to the /dev/FTDI, it ofcourse says that it's in use.. but when i run as root it does work. This is how i worked it out last time
[19:19] <fsphil-laptop> perhaps you can run cat /dev/FTDI as the user sending the data
[19:19] <fsphil-laptop> just before you send it
[19:19] <fsphil-laptop> then kill cat after it's done
[19:19] <TimZaman> And eventually i *did* split every file in 256bytes but thats because i sent a GPS string in between
[19:20] <TimZaman> fsphil but you cant read and write at the same time right?
[19:20] <TimZaman> fsphil, it couldnt hurt to connect the rx to ground, right?
[19:21] <fsphil-laptop> that should be fine
[19:21] <fsphil-laptop> worth trying yea
[19:21] <TimZaman> dont get why i didnt try that before
[19:26] <nosebleedKT> Lunar_Lander: humidity indicator :P

[21:36] <RocketBoy> and DC coupled

[22:14] <Lunar_Lander> cool
[22:17] <number10> I poped down to life sciences lab as they receive samples that are kept cool - smallest wat about 19cm cubed
[22:17] <RocketBoy> do they still do güe ice cream - nice boxed
[22:17] <RocketBoy> boxes
[22:18] <daveake> number10 19cm cubed is a useful size
[22:18] <number10> yes
[22:18] <number10> was the only one though - bought some off ebay was massive 29cm
[22:19] <jcoxon> RocketBoy, i never found those Gu boxes
[22:19] <RocketBoy> I have a couple
[22:19] <RocketBoy> 10cm cubes
[22:19] <jcoxon> they would be perfect
[22:20] <Randomskk> the gu boxes are amazing, also delicious
[22:20] <number10> lol
[22:20] <Randomskk> but I've only seen like two ever
[22:20] <number10> dont eat the box
[22:20] <fsphil-laptop> now he tells me
[22:22] <daveake> lol

[22:22] <Lunar_Lander> cool
[22:22] <fsphil-laptop> I saw the little tap covers that stilldavid used at B+Q this weekend
[22:22] <Lunar_Lander> jcoxon : I got mine in a pharmacy
[22:23] <Lunar_Lander> just asked for it
[22:23] <fsphil-laptop> they're a great size for a small payload
[22:23] <stilldavid> $.98 :)
[22:23] <stilldavid> and with two stuck together, a medium payload, too!
[22:23] <Lunar_Lander> hey stilldavid!
[22:23] <fsphil-laptop> bargin! they where £5 each here
[22:23] <Lunar_Lander> I saw your videos about flight 2 and 3 finally
[22:23] <Lunar_Lander> :)
[22:23] <jcoxon> stilldavid, you have the most unreliable radios
[22:23] <fsphil-laptop> about $8
[22:23] <jcoxon> they never work
[22:24] <stilldavid> jcoxon: tell me about it.
[22:24] <stilldavid> it's the GPS units. I'm doing something wrong, must be.
[22:24] <jcoxon> with all that sparkfun might behind you!
[22:24] <stilldavid> heh, or something :P if it weren't just me working on the payloads...
[22:24] <fsphil-laptop> is it the radios failing or just the gps?
[22:25] <stilldavid> just the gps.
[22:25] <jonsowman> which gps is it?
[22:25] <stilldavid> the radio sent the carrier signal throughout the entire trip.
[22:25] <stilldavid> GS407 based on uBlox5
[22:25] <jcoxon> did it work at all?
[22:25] <stilldavid> the first ~15m of flight :)
[22:25] <jcoxon> ha
[22:26] <fsphil-laptop> did it work after you recovered it?
[22:26] <stilldavid> then it just locked up for some reason.
[22:26] <stilldavid> yup. works a treat on the ground
[22:27] <stilldavid> I set it to airborne mode and then used the proprietary uBlox sentence mode
[22:27] <stilldavid> I think the latter was the mistake.

[22:27] <daveake> I used a GS407 on Cloud2. Worked fine once I soldered to it direct instead of using that piece-of-sh^%t Sparkfun connection board. I'd use it again but I haven't seen it since ... :p
[22:27] <jcoxon> stilldavid, thats been used successfully by others
[22:27] <jcoxon> daveake, stilldavid works at sparkfun!
[22:27] <daveake> :D
[22:28] <jcoxon> be kind and one day we'll get discounts
[22:28] <stilldavid> jcoxon: I also found 3 errors on the last G407 breakout...
[22:28] <jcoxon> or free shipping
[22:28] <daveake> That board is still rubbish :)
[22:28] <fsphil-laptop> lol
[22:28] <stilldavid> some of our stuff is really really uh & interesting.
[22:28] <stilldavid> that board has been through 15 revisions and only has one component on it.
[22:28] <daveake> The socket comes off the board very easily
[22:28] <stilldavid> so yeah. I feel ya.
[22:28] <fsphil-laptop> I'm starting to feel good about the fsa03 now :)
[22:29] <jcoxon> GPSbee
[22:29] <daveake> :D
[22:29] <jcoxon> all the way
[22:29] <stilldavid> daveake: it's also flush with the back of the module so you can epoxy a spare pcb across it to hold it in place
[22:29] <jcoxon> thats far more solid
[22:29] <fsphil-laptop> too expensive jcoxon
[22:29] <jcoxon> has a sensible breakout as well
[22:29] <stilldavid> I don't get gpsbees at cost :P
[22:29] <daveake> stilldavid - yeah, I was about to, then I dropped it one last time ...
[22:29] <stilldavid> bummer :( is it just the board that's busted or the module as well?
[22:29] <jcoxon> stilldavid, hehe
[22:30] <daveake> Module was fine.
[22:30] <daveake> I don't have it on account of it being somewhere in or near the North Sea ....
[22:30] <fsphil-laptop> he gone and got it wet :p
[22:30] <stilldavid> ah, duly noted then :)
[22:31] <daveake> I set it to airborne mode but then it became seaborne :p
[22:31] <fsphil-laptop> good flight that though
[22:31] <Lunar_Lander> xD but stilldavid found it
[22:31] <daveake> Yep
[22:31] <Lunar_Lander> :P
[22:31] <RocketBoy> noooo - "Gü withdrew from frozen foods in 2007 after disappointing sales of its ice cream and chocolate bombe products."
[22:31] <fsphil-laptop> they bombed out?
[22:31] <RocketBoy> ;-)
[22:31] <fsphil-laptop> don't think I ever got to try it
[22:32] <RocketBoy> so no more Gü boxes

[22:32] <Randomskk> oh D:
[22:32] <Randomskk> but they were so delicious
[22:32] <RocketBoy> and crispy
[22:32] <jcoxon> i'm wondering if these would work
[22:33] <jcoxon> it would be easy to remove the dividers
[22:33] <Lunar_Lander> XD
[22:33] <daveake> I'm going to take Buzz1 apart and put the bits in a slightly more insulating enclosure so the signal doesn't fly across the waterfall faster than the balloon rises
[22:33] <Lunar_Lander> I wonder what happens if you eat roasted kitchen paper
[22:34] <stilldavid> so I've got another 1500g balloon sitting under my desk, what should I do with it?
[22:34] <daveake> Then set it off under my second 1600g Hwoyee, with the hope that it gets a bit higher than the last one :)
[22:34] <RocketBoy> daveake: ha - i'm ready for it this time - have found out what was wrong with dl-fldigi
[22:34] <daveake> :D
[22:34] <RocketBoy> and got the AFC working
[22:34] <daveake> We all had trouble with that one!
[22:34] <daveake> Cool!
[22:35] <fsphil-laptop> I'll have to make sure I'm not heading out that day
[22:35] <jcoxon> RocketBoy, did you fix that bug?
[22:35] <daveake> I've got tons of work on next 3-4 weeks, then I'll see about launching from cambs
[22:35] <RocketBoy> turns out if you swich the squelch on the AFC is disabled
[22:35] <daveake> Ah
[22:35] <RocketBoy> switch
[22:35] <jcoxon> stilldavid, what make of 1.5kg?
[22:35] <fsphil-laptop> I think the AFC uses feedback from the decoder - so that makes some sense
[22:35] <stilldavid> kaymont
[22:36] <jcoxon> still got that ZP?
[22:36] <daveake> I'm kinda hoping for a trans-North-Sea flight, so I'll be needing a channel tunnel ticket
[22:36] <stilldavid> sure do. I think I might do some ZP tests with the 1.5kg, like ballast and such
[22:36] <jcoxon> yeah
[22:36] <stilldavid> I'm keen on doing a cross-country flight with the ZP starting from the west coast
[22:36] <jcoxon> stilldavid, i wonder whether just simple ballast would work
[22:37] <jcoxon> like sandbag style
[22:37] <jcoxon> so know masses
[22:37] <stilldavid> I've got a setup almost identical to the white star guys currently
[22:37] <jcoxon> sweet
[22:37] <stilldavid> maybe do a 0.5L test on this flight or something
[22:38] <jcoxon> with the 1.5 will you try for a float before hand like ballasthalo
[22:38] <jcoxon> or just dump on ascent
[22:38] <stilldavid> I think a float might be more fun and a better challenge
[22:38] <stilldavid> and for sure have a secondary cut-down
[22:38] <jcoxon> welcome to my world...
[22:39] <Lunar_Lander> XD
[22:39] <Lunar_Lander> jcoxon : are there any medical experiments that could be done on HAB?
[22:39] <jcoxon> not really
[22:39] <stilldavid> http://whitestarballoon.com/wp-content/uploads/2011/07/wsb1.png
[22:39] <Lunar_Lander> yea
[22:39] <stilldavid> huh, hadn't seen that before.
[22:40] <Lunar_Lander> but biologicals are possible :)
[22:40] <jcoxon> indeed
[22:40] <jcoxon> thats what CNSP do

[22:41] <jcoxon> i mean CNES
[22:42] <Lunar_Lander> ah
[22:42] <Lunar_Lander> I just remember a sad experiment from my biology book
[22:42] <Lunar_Lander> something about a small intestine (I think from a pig) being filled with sugar solution IIRC and then observed in a water bath
[22:42] <Lunar_Lander> or so
