[00:13] <Randomskk> also holy crap is N type ever easier to fit than sodding PL259
[00:14] <gonzo_> wash your mouth out. Mentioning the PL word on here!!!
[00:15] <Randomskk> I just wish my icom had something else on the back :P
[00:16] <gonzo_> always modable
[00:16] <Randomskk> not sure I wanna replace the connector on the back :P
[00:17] <Randomskk> though you're right it's pretty tempting. two N types would be glorios
[00:17] <Randomskk> glorious also
[00:17] <gonzo_> pft, you wus!

[04:00] <WB8ELK> Hi Ben...hopefully
[04:00] <WB8ELK> It went east 80 miles....then turned around and headed right back over our heads....now its about 200 miles west of me
[04:01] <WB8ELK> it has traversed Alabama both ways...part of GA...now MS and about to head into Arkansas
[04:01] <WB8ELK> hopefully I can get it to come visit you in CA
[04:01] <WB8ELK> It is -47 deg C inside the payload
[04:02] <WB8ELK> hearing it via a remote radio in Walla Walla, WA too
[04:02] <WB8ELK> on 14.103 MHz USB
[04:02] jolo2 (~jolo2@23.205.200.77.rev.sfr.net) left irc: Ping timeout: 240 seconds
[04:07] <nigelvh> Is it transmitting constantly?
[04:07] <nigelvh> I'm in Shoreline, WA
[04:07] <nigelvh> I'll turn on my rig.
[04:11] <nigelvh> WB8ELK?
[04:15] <WB8ELK> It transmits every 2 minutes
[04:15] <WB8ELK> at the top of each even minute
[04:16] <nigelvh> What mode presently?
[04:16] <WB8ELK> Morse Code message with callsign WB8ELK followed by altitude in Meters in Morse Code
[04:16] <WB8ELK> Then DominoEX16
[04:16] <WB8ELK> Followed by 110 baud ASCII RTTY - 200 Hz shift 8 bit no parity 1 stop bit
[04:16] <WB8ELK> Followed by the lat/lon in Morse Code
[04:16] <nigelvh> And you've got the dial on 14.103?
[04:17] <WB8ELK> 14.103 MHz USB
[04:17] <WB8ELK> the audio will be centered around 1200 Hz on the waterfall on dl-FLdigi at the moment
[04:17] <WB8ELK> callsign of WB8ELK2 on dl-FLdigi and hit Autoconfigure
[04:17] <WB8ELK> that will set your modes
[04:18] <WB8ELK> Upper Side Band mode
[04:18] <WB8ELK> on 14.103
[04:18] <nigelvh> K. I've got mine on, but I'm not sure I'm hearing anything. I do see around that frequency a slight color change in the waterfall, but not enough to get anything.
[04:18] <WB8ELK> It is transmitting right now
[04:18] <nigelvh> I am on the west side of the cascades though.
[04:18] <WB8ELK> I could hear it on the Walla Walla SDR radio just fine about 20 minutes ago
[04:18] <WB8ELK> websdr.org
[04:19] <WB8ELK> but then something happened to the Walla Walla SDR radio on 20m
[04:19] <nigelvh> Yeah, They're on the east of the cascades, which may have a difference.
[04:19] <WB8ELK> maybe

[04:31] <natrium42> hi WB8ELK
[04:31] <natrium42> very interesting flight, going the "wrong" way
[04:35] <nigelvh> It seems like occasionally I might be catching a glimpse of something, but nothing for sure yet.
[04:38] <WB8ELK> Yep...very interesting indeed...I've flown 80 miles east...then after it hit the winds above 60k it headed back west directly over my head here in Huntsville and continued on to the west...it's now 200 miles west of me.
[04:39] <WB8ELK> it's a Hwoyee 1600 gram with helium filled with 3 pounds of nozzle lift with 2 lbs 7 ounces of payloads....9 ounces of free lift

[06:04] <KT5TK> WB8ELK: Hey Bill, still there?
[06:06] <WB8ELK> yep...my 20 meter transmitter just died
[06:06] <WB8ELK> 11.5 hours
[06:07] <nigelvh> Nicely done!
[06:07] <WB8ELK> it was 200 miles west of here and still quite strong
[06:07] <WB8ELK> the 2m DominoEX on 144.34 is still transmitting
[06:07] <WB8ELK> the APRS is still working as well
[06:07] <nigelvh> Nice
[06:07] <WB8ELK> KT5TK...how did your solar power PSK31 work out...did you recover it?
[06:08] <WB8ELK> I hope that the batteries will warm up at sunrise and maybe the HF will start to work again
[06:08] <nigelvh> How long do you think the batteries might last?
[06:10] <KT5TK> Yes, was great. All packages recovered
[06:10] <nigelvh> KT5TK, BTW, I just finished the first pass at the board layout. I'll be sending it to you shortly.
[06:10] <KT5TK> http://tkrahn.dyndns.org/gallery2/main.php?g2_itemId=4560&g2_page=2
[06:10] <nigelvh> Also, congrats on the flight!
[06:10] <KT5TK> just preparing the pics & results
[06:11] <KT5TK> cool nigel
[06:11] <KT5TK> PSK worked all the way until the balloon popped
[06:12] <nigelvh> Why'd it stop?
[06:12] <KT5TK> Then the cords and antennas got winded up together
[06:12] <nigelvh> Ah
[06:12] <nigelvh> That would do unpleasant things.
[06:12] <bgelb> How much freq drift over temp?
[06:12] <KT5TK> searching the pic
[06:12] <bgelb> I think you said it was +1600Hz earlier.... then down to 1200Hz?
[06:13] <KT5TK> http://tkrahn.dyndns.org/gallery2/main.php?g2_itemId=4969
[06:13] <bgelb> trying to figure out where I should peg the waterfall before I go to sleep... :)
[06:14] <KT5TK> WB8ELK: Just set up my 20m rx in case your beacon comes back
[06:14] <KT5TK> APRS runs anyways
[06:14] <WB8ELK> hi Ben....my 20m transmitter was a 2N7000 final running 700 milliwatts Class-E by the way
[06:14] <bgelb> very nice
[06:15] <WB8ELK> it just died a few minutes ago after 11.5 hours
[06:15] <bgelb> yea, i saw
[06:15] <WB8ELK> it's now a steady carrier
[06:15] <bgelb> how were you keying it?
[06:15] <WB8ELK> turning on/off the synthesizer output
[06:15] <bgelb> oh hrm, interesting that its steady now
[06:16] <bgelb> steady 100% or, does it still turn on at top of the minute
[06:16] <WB8ELK> yep....won't last long although it works down to 4 volts
[06:16] <bgelb> two minutes, rather
[06:16] <WB8ELK> it went Bloop at the tail end of the last transmission
[06:17] <bgelb> was hoping it would come back in the daylight, but if its key down all night... might toast the batteries
[06:17] <bgelb> listened all day for it, but nothing :(
[06:17] <WB8ELK> it was -49 deg C in there for the past 5 hours
[06:17] <WB8ELK> I heard it great via an SDR web radio in Walla Walla, WA
[06:17] <WB8ELK> websdr.org
[06:17] <bgelb> better antennas than me no doubt :)
[06:18] <bgelb> prop prediction seemed to suggest there was a possibility, but guess not quite in the cards
[06:18] <WB8ELK> I'm using a vertical in my front yard.....had a great signal on it from 200 miles out....the 2m is running 25 milliwatts on FM....I can still hear it at 250 miles...KD0FW in Kansas City is hearing it now and copying the telemetry at 380 miles
[06:19] <WB8ELK> It was heard in the UK
[06:19] <WB8ELK> and I think Poland?
[06:19] <bgelb> very cool
[06:19] <WB8ELK> also cool that we had TWO 20 meter balloons up on the same day
[06:20] <KT5TK> WB8ELK on the walla walla SDR shall I use the 20m ssb or 20m cw range?
[06:20] <bgelb> hrm... no APRS for 18 mins
[06:21] <KT5TK> to hear the carrier?
[06:22] <WB8ELK> 20m ssb
[06:22] <WB8ELK> 14.1025 at the moment USB
[06:22] <WB8ELK> the carrier is warbling like a WSPR signal at the moment
[06:23] <griffonbot> @PD3EM: Heading out to the #HAB launch of Hyperion1. Track it via http://t.co/DNSb0fKM #UKHAS [http://twitter.com/PD3EM/status/237072201055080448]
[06:23] <KT5TK> Ah, ok got it
[06:24] <bgelb> so does that mean the synthesizer still working, but uC died, or something?
[06:25] <bgelb> what is the synthesizer...?
[06:25] <bgelb> DDS?
[06:25] <KT5TK> I hear nothing through the rf radio on my ground plane though
[06:25] <WB8ELK> A Cypress CY22393
[06:25] <WB8ELK> on 2m it puts out 25 milliwatts
[06:26] <WB8ELK> directly from the Cypress chip
[06:26] <WB8ELK> I bias it up to drive the 2N7000 on HF via Class-E and get about 750 milliwatts or more depending on the supply voltage
[06:27] <WB8ELK> I think the carrier that I hear on the Walla Walla SDR might be my signal
[06:28] <WB8ELK> probably only about 100 milliwatts now at that low voltage
[06:28] <WB8ELK> the battery was about 5.6 volts when it failed
[06:28] <WB8ELK> now I wish I had put my solar panel on it like KT5TK flew on his
[06:29] <KT5TK> Won't help on this time of the night
[06:29] <WB8ELK> LOL
[06:29] <KT5TK> but maybe tomorrow
[06:29] <nigelvh> Would have prolonged life during the day though
[06:29] <WB8ELK> try listening to it on 144.335 MHz FM....it's in range of Dallas area
[06:30] <WB8ELK> and getting close to being in range of Houston
[06:30] <KT5TK> Ah, ok I'll try
[06:30] <KT5TK> what ode?
[06:30] <KT5TK> mode?
[06:31] MrScienceMan (~zo@46.47.80.192) joined #highaltitude.
[06:31] <WB8ELK> 144.335 MHz FM....CW, DominoEX22 and 300 baud ASCII RTTY every minute
[06:32] <WB8ELK> KD0FW is still hearing it in Kansas City at 380 miles
[06:32] <nigelvh> Someone's blasting into Walla Walla
[06:32] <KT5TK> OK, will try
[06:33] <WB8ELK> I think that's my carrier on Walla Walla...it's warbling a bit like I'm getting here directly
[06:33] <Upu> morning all nice flight Bill :)
[06:34] <WB8ELK> Thanks....been a fun day....nice to have two 20m signals to listen to
[06:34] <WB8ELK> looks like my APRS froze up....-51 deg C in my 2m payload
[06:35] <WB8ELK> well...hopefully some of it will come back at sunrise
[06:35] <Upu> probably will
[06:35] <Upu> shame its floating the wrong way for us
[06:36] <Upu> ping costyn whats your payload called for today ?
[06:40] <nigelvh> Alright, I feel stupid. Had my rig on all evening listening for WB8ELK's payload, and finally realized the tuner wasn't powered, so I wasn't getting any signals.
[06:40] <nigelvh> OH!
[06:40] <nigelvh> it's sending something!
[06:41] <nigelvh> Or something is
[06:42] <KT5TK> Nothing on 144.335 MHz FM, don't have a good VHF location at my house though.
[06:43] <KT5TK> I whish I were at my QRL (KT5TK-15)
[06:43] <KT5TK> that's a 10 story building
[06:44] <WB8ELK> That would help...I live on a 500 tall mountain...great RF location and quiet out in the country
[06:44] <WB8ELK> 500 foot tall
[06:45] <nigelvh> I'm similarly on top of a hill at 500' overlooking the Seattle Area
[06:45] <WB8ELK> I can still hear my 25 milliwatt FM telemetry on 144.335 MHz but too weak to copy anything but the CW...I can barely copy the CW
[06:45] <KT5TK> You probably know about our really huge mountains in Houston...
[06:46] <WB8ELK> yep....20 foot tall would be considered huge
[06:46] <KT5TK> There you go.
[06:46] <WB8ELK> say hello to Andy for me by the way
[06:47] <KT5TK> I will. We've been talking about you and the old times today
[06:47] <KT5TK> BTW did you use Hydrogen in your current flight?
[06:48] <KT5TK> We had trouble to get He
[06:48] <WB8ELK> I can get a 300 cubic foot tank for $145 but had to get from a small gas supply store
[06:49] <WB8ELK> the big boy gas supply houses wanted upwards of $450 a tank
[06:49] <WB8ELK> Hydrogen was $35 a tank
[06:49] <WB8ELK> I've used hydrogen a lot for the Spaceport Indiana flights i've been doing since we can't get helium there
[06:49] <KT5TK> Yes, they actually didn't even want to sell it at all
[06:49] <WB8ELK> hasn't been any problems using hydrogen
[06:50] daveake (~daveake@daveake.plus.com) joined #highaltitude.
[06:50] <KT5TK> We'll probably need to, soon
[06:50] <WB8ELK> I have access to helium at the university high bay where they do the ozonesonde so used a quarter tank's worth today
[06:50] <WB8ELK> of helium
[06:51] <eroomde> we've always had free helium but i don't know if that's now time limited
[06:51] <KT5TK> Yes, university was our source for yesterday, too
[06:51] <WB8ELK> you can use a helium regulator if you get a CGA-580 to CGA-350 adapter
[06:51] <eroomde> the few recent hydrogen flights have been head-ache free anyway
[06:52] <KT5TK> I did a h2 flight some 25 years ago
[06:52] <WB8ELK> yep.. free (or cheap) helium is a thing of the past
[06:52] <WB8ELK> I actually did one with natural gas in the very early days
[06:52] <WB8ELK> my grandpa had a natural gas well...not much lift but it went up
[06:52] <KT5TK> It was in connection with a marriage.
[06:52] <KT5TK> Nothing blew up.
[06:53] <KT5TK> except for the marriage a few years later
[06:53] <eroomde> balloon widow
[06:54] <daveake> Unlike hydrogen, their bond was weak
[06:55] <eroomde> i think james coxon's other half has described herself as that once before
[06:55] <daveake> :)
[06:58] <WB8ELK> well...been a long day...heading off to bed in hopes of hearing something from my balloon in the morning
[06:59] <nigelvh> Similarly.
[06:59] <nigelvh> Nicely done WB8ELK
[06:59] <nigelvh> I'll scan around on my rig in the morning.
[06:59] <WB8ELK> thanks...see you all later

[10:52] <costyn> :(
[10:53] <costyn> the line was too thin to let it pay out ; we had no thick glvoes
[10:53] <costyn> so we let go the balloon and then ran while holding the apyload, but it was pulled from my hand and it bounched a couple times on the ground :(*
[10:53] <Upu> its back
[10:54] <costyn> guess that's what they meant with "should be able to fall down a flight of stairs"
[10:54] <Upu> lol not quite
[10:55] <costyn> 30K yessss
[10:55] <fsphil> ah, all going well
[10:55] <Upu> yup
[10:56] <costyn> yes, despite the rough takeoff
[10:56] <costyn> Upu: I did the extra squirts, looks like it hlpend
[10:56] <fsphil> yea, sounds like you might have a null in the antenna
[10:56] <Upu> does indeed :)
[10:56] <Upu> defintely fsphil
[10:56] <Upu> its going from ok to disappearing
[10:56] <costyn> fsphil: could be, because it's cutting out as it rotates
[10:57] <fsphil> if this gets to 40km there's a chance I might get it here at home
[10:57] <Upu> meant to burst at 35km
[10:57] <Upu> that said its Hwoyee
[10:57] <Upu> gone again totally for me
[10:57] <costyn> does it mean the signal in the not0-null area is stronger?
[10:58] <fsphil> good question
[10:58] <Upu> interesting not sure
[10:58] <Upu> I don't think promoting bouncing your payload along the ground before launch is a good idea though :)
[10:58] <costyn> it's also weaving back and forth on the waterfall
[10:59] <Upu> yeah its a little drifty
[10:59] <costyn> Upu: no, will bring gloves next time
[10:59] <Upu> strong again now
[10:59] <Randomskk> I don't think it would make it stronger in the not-nulls

[10:59] <Randomskk> surrounding your antenna in a faraday cage with a tiny hole doesn't give you a super strong signal out of the hole
[10:59] <Upu> true
[10:59] <Randomskk> putting a piece of card in front of a bit of a torch doesn't make the rest of it brighter

[13:24] <NSS> It is not designed to be a floater, but it is one of those new chinese Hywowee (sp?) balloons, that seem to be able to hold bck the pressure and become like super pressure balloon if you marginally inflate them.

[13:53] <DanielRichman> NSS: like this

[13:53] <NSS> how do you do that?
[13:54] <Randomskk> DanielRichman: I can too?
[13:54] <Randomskk> NSS: you just say his name
[13:54] <DanielRichman> Randomskk: fix was hotfix data["sentence_id"] += 500
[13:54] <Randomskk> ah ok
[13:54] <NSS> DanielRichman test?
[13:54] <Randomskk> we should keep a collection of signed hotfixes :P
[13:54] <DanielRichman> yup that worked NSS
[13:54] <DanielRichman> provided I'm awake, if you do that, phone vibrates so hopefully I'll notice
[13:55] <NSS> OK, cool, our flight is coming up soon, and want this not to be an issue.
[13:56] <NSS> The payload at surface temps is fine it ran at last testing for 3 weeks nonstop perfectly, but at 40 below thats another story.
[13:56] <DanielRichman> I see. We might be able to work out a more robust fix
[13:57] <DrLuke> you should try saving the ID in the EEPROM of a micro
[13:57] <NSS> I e mailed James last night with a thought, can we ad another feature to the map? I'd love to see a greyline feature if possible?
[13:57] <Randomskk> greyline?
[13:57] <DrLuke> that way even if your micro resets, the ID will continue
[13:58] <NSS> where the sun is up and where it is not
[13:58] <DrLuke> that's a good idea
[13:58] <DrLuke> but make it toggleable
[13:58] MoALTz (~no@host-92-2-143-139.as43234.net) left irc: Ping timeout: 245 seconds
[14:00] <NSS> especially with all these long duration flights happening, having the info if the balloon is in sun or not would be very helpful.
[14:00] <Randomskk> the terminator changes at altitude though
[14:01] <DrLuke> why would it matter if the balloon is in the sun or not while it's in the air?
[14:01] <Randomskk> loads of possible reasons
[14:01] <NSS> true. I use a astronomy program to show me the time difference at altutude, it can be long like 40 minutes even, wonder if it could be modded to parse the balloons altitude and make adjustments he he he.
[14:01] <Randomskk> solar panels, solar heating of the envelope, long duration floaters, etc
[14:02] <DrLuke> hm
[14:02] <DrLuke> wasn't there something about some muslim law on the burj dubai bein delayed by 2 minutes if you're above a certain floor because the sun set later? :P
[14:03] <NSS> yup on our next flight I will be able to tell via the telemetry because we have solar panel voltage measured.
[14:03] <DrLuke> cool!
[14:03] <DrLuke> where do you mount the panel?
[14:03] <DrLuke> do you have pictures?
[14:04] <NSS> no pics yet, panel is flat on the top of the paylod

[14:28] <NSS> I was just wondering if a multi mode could be mde. Like right now it isn't a big deal I have two windows open, one set for Domino and the other for RTTY so i don't have to change modes all the time. it works, but would be cool if it could be done in one window ya know?
[14:29] <Darkside> you'd have to switchmodes
[14:29] <Darkside> fldigi won't decode multiple modes at the same time
[14:29] <Darkside> and it'd probably be a pretty big change to make it do that
[14:30] <fsphil> massive
[14:30] <fsphil> there is a button to switch between defined modes
[14:32] <NSS> yes, but when running un monitored like last night with the WB8elk flight not here to switch back and forth. two windows opens fine, just klunky
[14:32] <fsphil> yea. adding multi modes is a big job
[14:33] <NSS> Like I said I have the program opened up twice right now. One is listening for Domino and the other for RTTY and it works just fine it decodes and uploads as if only one was running they on't seem to ee echother at all.

[15:23] <fsphil> really? euu
[15:23] <Randomskk> ikr :( :(
[15:23] <fsphil> the 857 has an N socket for that, and the SO239 for HF
[15:23] <fsphil> I'd prefer N for both
[15:23] <Randomskk> yes
[15:23] <Randomskk> I'd prefer N for everything at the moment
[15:23] <Randomskk> having just fitted two N plugs onto some W103
[15:24] <Randomskk> my goodness
[15:24] <Randomskk> never fitting PL259 again
[15:24] <Darkside> lol
[15:24] <Randomskk> sooooo much easier to put onto coax
[15:24] <Randomskk> you just make one cut, no fucking with the right length of braid and insulator and centre conductor
[15:24] <Randomskk> and then you just solder one pin onto the middle, and it's the easiest thing to solder
[15:24] <Randomskk> slide a few more bits on and you're done!
[15:24] <Darkside> i prefer the crimp connectors
[15:24] <Randomskk> and better yet it's a much higher quality connection /and/ more weatherproof to boot
[15:24] <Darkside> well, for the shield anyway
[15:24] <Randomskk> crimp ones are nice too if you have a crimper
[15:24] <Darkside> yeah, i do
[15:24] <Randomskk> but the N type I have goes onto the shield soooo nicely
[15:25] <Randomskk> it's just a push thing
[15:25] <Darkside> i've got crimpers for RG-8, 58, and 213
[15:25] <Darkside> makes a very secure connection
[15:25] <Randomskk> yea
[15:25] <Randomskk> definitely

[17:24] <Laurenceb_> much better than chipcon
[17:25] <Laurenceb_> but its the same ic from rfm22b, so you know the beal
[17:25] <Laurenceb_> *deal
[17:25] <Randomskk> fair enough
[17:25] <Randomskk> I've not used the rfm22b actually
[17:25] <Laurenceb_> 4462 is the successor
[17:25] <Randomskk> it seems a bit unreliable in flight?
[17:25] <Laurenceb_> thats the piss poor rf layout and xtal on the modules imo
[17:25] <Randomskk> yea okay
[17:26] <Randomskk> I'll give it a shot.

[17:26] <fsphil> howdy jcoxon
[17:26] <Randomskk> any idea where I might get some 4462s?

[17:44] <DrLuke> I forgot to tell you that the code completely removes the ability to use PWM
[17:44] <Laurenceb_> i think youd need to run it off a tcxo for it to be practical as an uplink

[18:01] <Lunar_Lander> you have like more the WYSIWYG approach, but it is intuitve after a while
[18:01] <Lunar_Lander> you like select if you want a section or subsection from a dropdown menu and it handles the rest
[18:01] <Lunar_Lander> it also understands if you like type \frac

[18:38] <Lunar_Lander> hi costyn
[18:38] <Lunar_Lander> how was it?

[18:42] <costyn> not sure, but the payload had a bumpy start (wrong liftoff procedure by us) so I think it switched off during that
[18:42] <costyn> pictures stop just before launch

[18:44] <Lunar_Lander> oh
[18:47] <fsphil> awww
[18:47] <costyn> Lunar_Lander: pro-tip: don't use too thin of a line (no kite-line) and bring gardening or winter gloves to be able to let up the balloon gently
[18:47] <Lunar_Lander> yea
[18:48] <Randomskk> costyn: what line were you using?
[18:48] <Randomskk> I usually use 1mm nylon and have no issues letting the balloon up with it in bare hands
[18:48] <Randomskk> there's a technique, if you keep letting short bits up and so swapping between hands
[18:48] <Randomskk> rather than letting it slip through your hand or anything
[18:51] <costyn> Randomskk: kite line, was too thin to hold comfortably
[18:51] <Randomskk> fair enough
[18:51] <costyn> Randomskk: yes, I thought of that as we were standing there but couldn't convey that to my collegue who was holding the balloon
[18:51] <Randomskk> costyn: ah.
[18:51] <costyn> Randomskk: and thought his method would work too, which it didnt :(
[18:51] <Randomskk> oh well
[18:51] <Randomskk> lesson learnt
[18:51] <costyn> definitely
[18:51] <costyn> next time i'll have to brief them better on it
[18:53] <LazyLeopard> Presumably nothing as simple as the camera having an auto-switch-off time...
[18:53] <costyn> but everything went pretty well considering it was my first. I put in enough gas in a SuperFloat 1600, I got all my electronics right
[18:53] <costyn> LazyLeopard: not sure, I think we tested it beforehand by having it take pictures for some lenght of time
[18:53] <costyn> LazyLeopard: but I will check into that of course
[18:54] <LazyLeopard> Wouldn't be the first time something like that stopped a camera before launch... ;)
[18:54] <costyn> hehe

[19:15] <HixPad> Hi guys, what's the URL of the party balloon place to get helium from? I've managed to lose it from bookmarks yet again
[19:15] <Darkside> BOC?
[19:16] <HixPad> Nope, there was a place I think it was cambs it was party balloons or similar
[19:17] <HixPad> Last time i spoke to BoC they were loony expensive unless you were tade
[19:18] <HixPad> Also I'm going to sat start building my tracker soon. Am I correct in thinking that the gps should live away from the rf module?
[19:18] <costyn> HixPad: doesn't really matter
[19:18] <Darkside> as long as they aren't right next to each other its fine
[19:18] <costyn> HixPad: as long as you keep your gps module away from any keychain camera's :)
[19:18] <Darkside> hehe
[19:19] <HixPad> :) saw something on that joys of eBay purchases
[19:19] <costyn> Darkside: is it just shoddy electronics and shielding and bad luck that the keychain camera's block gps signals?
[19:20] <costyn> Darkside: I had a nice flight today, missed you on a globaltuner, although we did have enough trackers fortunately
[19:20] <costyn> Darkside: unfortunatley camera failed on liftoff and we have no inflight pics
[19:20] <Darkside> damn
[19:20] <Darkside> costyn: yeah, i'm not sure what the deal is with the keychain cameras
[19:20] <Darkside> i'm guessing theres a harmonic of some internal clock that happens to lie on the GPS L1 freq
[19:20] <HixPad> No pics, that's a killer
[19:21] <Darkside> costyn: so the camera failed when the payload bounced?
[19:21] <costyn> Darkside: I think so
[19:21] <costyn> Darkside: maybe a button was pressed inadvertantly
[19:21] <Darkside> mm
[19:21] <Darkside> why did it hit the ground?
[19:21] <costyn> Darkside: would be nice to have the script turn off all buttons execpt the shutter button to interrupt the script
[19:22] <Darkside> it didn't look too windy
[19:22] <costyn> Darkside: shitty launch technique by noobs :)
[19:22] <Darkside> heh
[19:22] <costyn> should've taken my time and thought about it longer, but it seemed like a good idea at the time
[19:22] <Darkside> hey, we've done some silly launches
[19:23] <Darkside> we had a big public launch, where we thought it'd be cool to lay out the balloon train on the ground, and let the balloon go at one end
[19:23] <Darkside> and let it pull everything up
[19:23] <costyn> what happeend?
[19:23] <Darkside> one payload got caught on grass, and anchored it to the ground
[19:23] <Darkside> so it didn't go anywhere :P
[19:23] <costyn> hehe
[19:24] <costyn> well we got that bit right, we had it all lifted off the ground before we let anything go
[19:24] <Darkside> we've also had our share of 30-45 degree launches

[19:24] <Darkside> check that out
[19:24] <Darkside> whatch how ed launches it
[19:25] <Darkside> very long line, not much lift on the balloon, and wind
[19:25] <Randomskk> lol that was a silly launch
[19:25] <Randomskk> so little gas in that balloon
[19:25] <Darkside> yeah
[19:26] <Darkside> and how ed had to run under the balloon
[19:26] <Randomskk> ed looks so confused when the string starts coiling on the ground
[19:26] <HixPad> Are there pics from yesterday's launch? Should've been good with the vis
[19:26] <Darkside> yup
[19:26] <costyn> brb... baby crying :()
[19:26] <Darkside> Randomskk: i've done one of those now
[19:26] <Darkside> that kind of launch
[19:26] <Darkside> was fun
[19:26] <Darkside> i just ran with the payload sitting in my hands in front of me
[19:26] <Darkside> and it just lifted out of my hands
[19:28] <Randomskk> hehe
[19:28] <Darkside> urgh
[19:28] <Darkside> we're still missing writeups for horus 24-27
[19:28] <Darkside> i think terry has been procrastinating and has been working on a tool to generate flight stats from the json dumps
[19:29] <Randomskk> hehe
[19:30] <Darkside> also the video for horus 26/27 isn't finished yet
[19:31] <Darkside> lots of material going into that one
[19:31] <Darkside> annoying thins was we didn't have a decent camera in the horus 27 chase car, only my DSLR
[19:31] <Darkside> which doesn't do video very well
[19:32] <Darkside> and, well, we ere kind of preoccupied trying to get through the extremely dense scrub in the toy 4wd
[19:32] <Randomskk> :P
[19:32] <Darkside> took us a good half an hour to drive 2km

[19:33] <Darkside> tbh the other 4wd would have had problems too
[19:33] <Darkside> like, we had to get out and pull trees to the side so we could get through a lot
[19:34] <Darkside> regularly check behind to make sure we hadn't set anything on fire with our exhaust
[19:34] <HixPad> Trees where's daveake
[19:34] <Darkside> lol
[19:34] <Darkside> these weren't big trees
[19:34] <Darkside> just scrubland
[19:34] <Darkside> we call it mallee scrub
[19:35] <Darkside> though the balloon train did land across multiple trees
[19:35] <Darkside> with each payload sitting nicely between the trees, easy to get to
[19:35] <Darkside> horus 26 landed the same way, but with every payload IN the tree
[19:35] <Darkside> trees*
[19:39] <Lunar_Lander> hey Darkside
[19:39] <Darkside> hi Lunar_Lander
[19:39] <HixPad> Nope still can't find decently priced helium. Any pointers?
[19:40] <Randomskk> helium is expensive
[19:40] <Darkside> HixPad: what prices are you seeing
[19:40] <Darkside> how much got a 3.6m^3 bottle
[19:40] <HixPad> Yup, but a relatively cheap source. Or is hydrogen viable for a launch
[19:40] <Darkside> how much for*
[19:40] <Darkside> HixPad: for a first launch i'd reccomend helium
[19:40] <Darkside> but thats me
[19:40] <HixPad> Fair nuff
[19:41] <Darkside> i'm not 100% sold on hydrogen launches and their safety just yet
[19:41] <Darkside> i think it's just a matter of time before something goes wrong at a launch
[19:41] <Darkside> and someone gets hurt
[19:41] <HixPad> Haven't got prices with me at mo but it was pretty steep. Plus 15 COLLECTION fee from BOC
[19:41] <Darkside> mm
[19:41] <Darkside> so i think our price in australia is about AUD$200 for a bottle
[19:42] <Darkside> which is about 130 pounds
[19:42] <HixPad> whoaa. Good old rip off Britain
[19:42] <Darkside> HixPad: that price is with discount

[19:49] <HixPad> But that's probably covering ground that has been previously done
[19:49] <Darkside> yes, but its still worth learning

[20:00] <Darkside> but it's not just a pcb design tool
[20:00] <Darkside> its a fully integrated develop environment, to go from schematic and code to pcb nd fpga design

[20:06] <Elmar_PD3EM> here its 22:05 local time
[20:06] <Elmar_PD3EM> it was 35 C earlier today (during costyn's launch
[20:07] <HixPad> 23.8 here shocking for blighty
[20:07] <Darkside> as humid tii?
[20:07] <Darkside> too*
[20:07] <HixPad> Nope 61
[20:07] <Darkside> thats not as bad
[20:07] <Darkside> we've done chases in >40 degC weather before
[20:07] <Darkside> but no humidity
[20:07] <Darkside> so its more tolerable
[20:08] <HixPad> Humidity sucks, pun fully intended
[20:08] <Elmar_PD3EM> it was less humid during the day
[20:08] <Elmar_PD3EM> true
[20:10] <Elmar_PD3EM> The only humidity that doesn't suck is coming from a beer bottle ;-)

[20:11] <HixPad> Anyway back on track. So if I put rf on a board and put gps on other side as far away as possible should be ok then?
[20:12] <Darkside> yeah
[20:12] <HixPad> Cool
[20:12] Hoppo (~johnhopki@213.86.244.72) joined #highaltitude.
[20:12] <Darkside> its generally not a problem
[20:13] <Darkside> my current gen telemetry payloads have the gps antenna about 4cm from the rf output socket
[20:13] <Darkside> http://rfhead.net/wp-content/uploads/2012/05/DSC_5655.jpg
[20:14] <HixPad> Mmm tiny, nice. Is it arduino pro mini based
[20:14] <Darkside> well
[20:14] <Darkside> its just an atmega328
[20:14] <Darkside> the arduino ide thinks its an arduino pro mini
[20:14] <Darkside> but i don't program it via a serial bootloader
[20:14] <HixPad> Ok cool, kinda what I was planning
[20:15] <Darkside> its what most people here do :-)
[20:15] <HixPad> Yup KISS
[20:15] <Darkside> yep
[20:15] <HixPad> and I'd be the S part
[20:15] <Darkside> also i didn;'t see the point in putting a serial progamming header on if i was going to have to use the ISP to flash a bootloader anyway
[20:15] <HixPad> Both in fact
[20:15] <Darkside> i may as well just program via ISP, and arduino can do that easily
[20:17] <HixPad> Prob reason I've gone eagle as everything is there for you
[20:17] <HixPad> Just a case of modding .sch and .brd
[20:17] <Darkside> well
[20:17] <Darkside> i wouldn't reccomend modifying the pro mini design
[20:17] <Darkside> start from scratch
[20:18] <HixPad> Ok but I've got something to work from and refer back to
[20:18] <nigelvh> Yeah, a tracker's a different beast.

[21:00] <jcoxon> Elmar_PD3EM, congrats on the launch
[21:00] <jcoxon> easier to find then the last payload you recovered?
[21:01] <Elmar_PD3EM> Thanks jcoxon but all te credits to costyn! it was his launch but it was great to be there
[21:01] <jcoxon> lots of listeners
[21:03] <Elmar_PD3EM> jcoxon: a lot has changed since that time! the rtty works much better and I was (together with Rob PA3BXR) prepared for good tarcking
[21:03] <Elmar_PD3EM> indeed lots of listeners. Looks like a record from PA-land
[21:06] <Elmar_PD3EM> We've got some new HAB listeners now :-)
[21:06] <jcoxon> great
[21:07] <Elmar_PD3EM> some of them were normally only tracking weather sondes
[21:08] <Upu> ours are more interesting than Sondes :)
[21:09] <jcoxon> the winds are turning

[21:21] <number10> I was going to take a shovel with me and bury the payload ;)
[21:21] <Upu> lol
[21:22] <Upu> so more string next time then ?
[21:22] <Upu> when your last receiving station is M0DTS you're in trouble :)
[21:23] <Upu> Two reasons 1/ He's miles up North 2/ He's got big antennas
[21:23] <merv> Dave ake was concerned about our NOTAM buit I have it here and we were cleared to launche eithe 18th or 19th between 1000 and 1400 local so no problem
[21:23] <Upu> I think it was the direction was stipulated but wouldn't worry about it now
[21:24] <Upu> love the picture of the bear
[21:24] <DrLuke> it's so cute
[21:24] <number10> there was problems with the telemetry strings uploading to spacenear - last one was from me and did not apear..
[21:24] <number10> I copied daveake M0MDB : HAM-1,104,130215,+5157.2784,+00032.0033,00726*e9cd and he managed to get it upload
[21:25] <Upu> did you try the manual upload ?
[21:25] <Upu> or Daveake did it ?
[21:25] <number10> daveake did so when I went out - so he knows what was wrong mabe
[21:25] <Upu> I think the check sum was wrong not sure
[21:25] <merv> ah the direction yes when we launched it was blowin south easterly but the wind shifted 60 seconds afrter it left our hands ;-)
[21:26] <Upu> but got it on the map
[21:26] <Upu> sure merv :)
[21:26] <Upu> still glad you got it back
[21:27] <merv> yes we were very relieved and leadned a lot
[21:27] <merv> learned
[21:27] <Upu> flying again ?
[21:29] <merv> most certainly but we intend to be a bit more careful to only launch when the prediction drops us in east sussex or kent next time
[21:29] <Upu> yeah or move launch sites is another option
[21:30] <Upu> and use a longer string between the payload and balloon
[21:30] <Upu> generally we do 10 meters from balloon to chute, then 20 meters to the payload
[21:31] <Upu> I think the train for Pi / uAVA and Buzz was 60 meters long :)

[21:51] <jcoxon> we could still pull it off but would need to launch from Spain

[22:02] <fsphil> how much I wonder

[22:03] <Upu> Depends if you get them from Clydespace :)
[22:03] <Upu> I think they are about £65 a cell
[22:03] <fsphil> eek
[22:03] <Upu> its hard to get an exact price
[22:03] <nigelvh> Until they bill you
[22:04] <Upu> but if you were doing a solar powered high pressure that could be up along time its the only real option
[22:04] <fsphil> I'm gonna try the supercapacitor for the solar beacon I've been thinking about
[22:04] <fsphil> although that won't have gps
[22:06] <Upu> whats it going to transmit ?
[22:07] <fsphil> two beeps when the cap charges to a certain level. although there's no reason it can't have a connection to a proper flight computer
[22:07] <fsphil> the flight computer would keep updating it with the coordinates until the battery ran out
[22:08] <fsphil> the beacon would just transmit the last coordinates it was told
[22:08] <fsphil> it's more for signaling "it's here somewhere"
[22:09] <fsphil> so at least you'd know you where searching the right mountain side

[22:14] <nigelvh> If I recall, KT5TK is in texas.
[22:14] <MrCraig> I also switched to the atmega :-) It does make things a bit too easy.
[22:15] <nigelvh> The atmega is handy
[22:15] <MrCraig> apparently a small group at the hackspace were planning a balloon flight, but it's a project that didn't get off the ground (excuse pun)
[22:16] <fsphil> that's quite a shift MrCraig
[22:16] <MrCraig> Yeah, it's been interesting to say the least. I have been driving 13 years and have to take a test again next week (in plenty of time for my international expiring)
[22:17] <nigelvh> In general, I do think that having to retest occasionally might be good.
[22:17] <MrCraig> I'm a little concerned actually about tracking - I won't have you all in the UK to help out.
[22:18] <nigelvh> Tracking around here is a bit different
[22:18] <nigelvh> On our flights, at the launch site we set up with some big yagis and whatnot, Then another portion of the team goes on chase and tries to track while driving.
[22:19] <MrCraig> yup - at least the ocean isn't so close to me though. I just got my parachutes mailed over from the UK, and requested that my old lasseniq's and ntx2's get shipped to save me buying alternatives. (It's cheaper than buying new)
[22:20] <MrCraig> I think I might have to do the same with some members of the makerspace (hackspace)
[22:20] <fsphil> you do at least get to use aprs MrCraig, if you get an amateur license
[22:20] <nigelvh> Exactly
[22:20] <MrCraig> so what's an apr then?
[22:20] <nigelvh> We get to use amateur radio in the air.
[22:21] <fsphil> same idea as spacenear really, transmit your position and lots of stations relay it to the internet
[22:21] <nigelvh> Automatic Packet Reporting System
[22:21] <MrCraig> cool :-)
[22:21] <fsphil> you can't transmit as often with it though
[22:22] <MrCraig> With the arduino I think I can actually program in fair delays - that was a chore with the pic assembler.
[22:22] <nigelvh> Yeah, a packet once a minute or so.
[22:23] <fsphil> AVRs are much nicer than PICs
[22:23] <fsphil> from a programming point of view anyway
[22:23] <MrCraig> Some of the other members fly quad-copters and x-mit video or images to ground. They tried to push their radio's on me, but I was concerned with those data rates over large distances.
[22:24] <fsphil> wise
[22:24] <MrCraig> I'm guessing I can't transmit image data through aprs?
[22:24] <fsphil> not quickly
[22:24] <fsphil> although
[22:24] <fsphil> if you put a packet out every 10 seconds, you'd get the same sort of speeds the 300 baud rtty does
[22:25] <fsphil> you'd probably get shouted at for transmitting that much on the common aprs frequency
[22:26] <fsphil> aprs in its most common form runs at 1200 baud
[22:26] <MrCraig> I may be better off finding a frequency to sit on and doing continuous transmission throughout. I remember that my last flight was clearly audiable right up to burst on just a whip antenna.
[22:27] <MrCraig> it went crazy shortly after... but soldering while on narcotics will do that.
[22:27] <nigelvh> Yeah. With my next flight, I'm going to aim for a frequency agile transmitter, so I can sit on one frequency, and occasionally send an APRS packet to get the advantage of the listeners.
[22:27] <fsphil> good idea
[22:29] <MrCraig> hmm, I might push the envelope - use 50 baud for telemetry, but punch it up to somewhere around 9600 for data (for giggles to see if it'd work)
[22:29] <nigelvh> If you're aiming for APRS, 9600 only happens on 70cm. The 1200 happens on 2m.
[22:29] <fsphil> any data rate will work with sufficient power :)
[22:29] <nigelvh> Also, 2m APRS is leaps and bounds more common than 70cm APRS
[22:29] <fsphil> 1200 baud has been done with Tim's flights
[22:30] <MrCraig> oooh the power regs are probably a lot more flexible here.
[22:30] <nigelvh> up to 1500W
[22:30] <nigelvh> If you can carry the battery
[22:30] <fsphil> yes, but you're still limited by battery capacity
[22:30] <nigelvh> My usual transmitters are around 1/4W
[22:30] <fsphil> you could do 1500W but only for a second :)
[22:30] <MrCraig> hmm how many balloons and chutes would I need to carry a lead acid 1500W supply... lol
[22:31] <fsphil> oh just one of each. just scary big ones that requires cranes to launch :)
[22:31] <nigelvh> I've done APRS on a flight and it worked well till the transmitter died.
[22:31] <fsphil> don't launch near expensive cars either
[22:32] <MrCraig> true that!

[22:32] <fsphil> 9600 baud would be neat. you'd get a 320x240 image in about 15 seconds
[22:33] Action: MrCraig pokes KT5TK to see if he has a notification script.
[22:33] <MrCraig> fsphil - I think it'd be a worthy experiment to do too.
[22:34] <fsphil> Texas is so big, it'll probably take the signal a few minutes to travel the fibre optic cable to him
[22:34] <MrCraig> 640x480 over 30 seconds or so.
[22:34] <fsphil> oooh yea, push the resolution
[22:34] <MrCraig> seriously, yes. Everything here is big too. Even the damn insects. I think the starship troopers movie was inspired by texas.
[22:34] <fsphil> hah
[22:35] Action: fsphil scribbles notes on his "Places to nuke from orbit"
[22:35] <MrCraig> There have been some amazing electrical storms the past few days. Though I know it would make tracking a challenge, I'd love to fly through one of those and get some snaps. One storm was lighting the sky for minutes at a time.
[22:36] <fsphil> <envy mode> You lucky git
[22:36] <MrCraig> lol it would be incredible to get images of lightening from above the cloud
[22:37] <fsphil> there's a CHDK script for triggering the camera during a strike
[22:37] <MrCraig> I really thing tracking in an electrical storm would be a bad idea though - lets errect a lightening rod from the car and go for a drive. hmmm
[22:37] <fsphil> keep the antenna inside and near a window
[22:37] <MrCraig> seriously?! so cool - I am gonna fly a storm!
[22:38] <fsphil> you might have me and eroomde over too :p
[22:39] <MrCraig> I got a guest bedroom
[22:40] <fsphil> that's very tempting. not this year though :)
[22:40] <fsphil> I have to survive australia first
[22:40] <MrCraig> I'm making a point of going out and doing something each weekend while I'm here - I may only get a year or 18 months. I hope to make several weekends available for flying, expenses and girlfriend permitting.
[22:40] <MrCraig> <return envy glare>
[22:41] <fsphil> there is no </envy> tag btw :)
[22:41] <MrCraig> I do have an envy domain though
[22:41] <MrCraig> I'm holding on to digitalenvy.co.uk for a future project.
[22:42] <fsphil> I'm going to see an eclipse during the rainy season, so it might be a bit of a silly trip
[22:42] <fsphil> nice domain
[22:42] <MrCraig> ta. So you'll be flying a balloon on your trip too?
[22:43] daveake (~Dave@daveake.plus.com) joined #highaltitude.
[22:43] <MrCraig> hey daveake
[22:43] <fsphil> I'm considering it
[22:43] <daveake> hiya
[22:44] <MrCraig> I think that inspite the added complications, getting permissions, and moving through customs with lots of latex - it's an opportunity worth taking.
[22:44] <MrCraig> my opinion.
[22:45] <fsphil> if I did it wouldn't be chased
[22:45] <fsphil> also it's a bit near the east coast where I'm going
[22:45] <fsphil> well, not near it - it's on the east coast
[22:46] Laurenceb_ (~Laurence@host81-151-162-14.range81-151.btcentralplus.com) left irc: Ping timeout: 276 seconds
[22:46] <fsphil> not sure they'd appreciate a payload landing in the reefs though
[22:46] <MrCraig> So you'd need a day with a westerly wind
[22:47] <fsphil> and a massive forrest park to the west
[22:47] <fsphil> -r
[22:47] <fsphil> wow that's huge
[22:47] <MrCraig> oh ofcourse - you like to land in trees..
[22:48] <fsphil> would at least be familiar territory :)
[22:48] <MrCraig> lol
[22:48] <fsphil> I gotta visit that forest park
[22:49] <MrCraig> hmm, roswell isn't far from here. "No honestly, it really was a weather balloon!"
[22:49] <fsphil> hah
[22:49] <fsphil> a likely story
[22:50] <MrCraig> *sigh* slightly frustrated that I have to wait it out for components to arrive.
[22:51] <fsphil> on the plus side, sparkfun is local-ish
[22:51] <MrCraig> yeah - and there's a mouser within driving distance too
[22:51] <nigelvh> Sparkfun ships quickly
[22:51] <nigelvh> Digikey ships very very quickly
[22:52] <MrCraig> I'm actually having that pcb that you handed to me shipped over nigel - I already have all the components required to build it
[22:52] <MrCraig> it's just the wait for them to cross the atlantic
[22:53] <MrCraig> The one disappointment I've had with Arduino is.... Serial.send('text').... what?! I don't even have to code my own uart?!
[22:54] <nigelvh> What PCB?
[22:54] <MrCraig> the AtMega pcb
[22:54] <nigelvh> I'm pretty certain you're thinking of a different nigel
[22:54] <nigelvh> I haven't given anyone PCBs
[22:54] <MrCraig> I just came to the same conclusion, it was nigey
[22:54] <nigelvh> Yeah
[22:55] <nigelvh> I live in Washington
[22:55] <fsphil> it's easy to confuse that with cardiff :)
[22:55] <MrCraig> lol
[22:55] <MrCraig> Washington state?
[22:55] <nigelvh> Yeah, washington state
[22:55] <MrCraig> I was up in seattle only a few weeks back, I'm wearing my space needle t-shirt
[22:55] <nigelvh> Did you actually go on the space needle?
[22:56] <MrCraig> Yus :)
[22:56] <MrCraig> but I missed out on the sci-fi museum, dang it
[22:56] <nigelvh> I've only ever been once to the space needle. It's an expensive tourist attraction.
[22:56] <nigelvh> Most locals rarely go.
[22:56] <nigelvh> The sci-fi museum is cool though.
[22:57] <MrCraig> and actually, of the very few (two) states I've visited, it's the one most easily confused with cardif. Same weather.
[22:57] <Lunar_Lander> hi daveake MrCraig nigelvh fsphil
[22:57] <MrCraig> hola Lunar_Lander
[22:57] <nigelvh> Howdy
[22:57] <fsphil> multiping
[22:57] <Lunar_Lander> :)
[22:57] <nigelvh> Ping ALL THE PEOPLE
[22:57] <Lunar_Lander> xD
[22:57] <Lunar_Lander> !all
[22:58] <MrCraig> fsphil - guys don't usually share that with an audiance... well some do I guess.
[22:58] <nigelvh> HAHA
[22:58] <MrCraig> damn, I misread you too lol
[22:58] <Lunar_Lander> ah as we got an american here now
[22:58] <Lunar_Lander> nigelvh, do you know of "Into the wild" the john krakauer book?
[22:59] <nigelvh> Yes
[22:59] <Lunar_Lander> I somehow rediscovered the story four days ago
[22:59] <Lunar_Lander> and I was thrilled
[22:59] <Lunar_Lander> it's like the 20th anniversary of it happening
[22:59] <nigelvh> Yeah, they did that movie not too long ago.
[22:59] <Lunar_Lander> yea
[23:00] <fsphil> midnight
[23:00] <nigelvh> 16:00
[23:00] <Lunar_Lander> I read quite a lot of stuff, like that Krakauer and Penn insisted on he poisoned himself but I also think he just starved to death
[23:00] <Lunar_Lander> 1 am
[23:01] <MrCraig> looks like KT5TK flys out of houston - that'd be a nice road trip.
[23:02] <nigelvh> Yep
