[00:25] <lz1dev> lol
[00:26] <ulfr> Someone had to circle a bit?
[00:26] <lz1dev> that must be autopilot tho
[00:26] <lz1dev> you cant circle like that manually can you?
[00:29] <SpeedEvil> I've never tried. Can you get me a go in a a350?
[00:31] <lz1dev> you have a death wish or something?
[00:34] <ulfr> At least something
[00:34] <ulfr> I mean the resolution isn't great.
[00:34] <ulfr> and pilots can keep a pretty tight track
[00:42] <zzqa> kc2pit: I haven't ever ordered from them. Their tindie page says ships in 2 days, but they're shipping "China Post Standard Ground Rate" aka slow boat
[00:46] <kc2pit_> zzqa: Just talked to somebody else who said it took less than 2 weeks, which is good enough for me.
[00:46] <zzqa> kc2pit: their aliexpress.com store guarantees arrival time of 39 days or your order is free
[00:47] <zzqa> ah nice
[00:47] <zzqa> you going to do VHF, UHF, or both?
[00:47] <kc2pit_> As long as it's not the sort of shipping that takes so long you forget that you ordered it.
[00:47] <kc2pit_> Figuring VHF only.
[00:47] <zzqa> I had written off the UHF module until I saw in the config guide that you can turn off emphasis so 9600 buad should be doable
[00:48] <zzqa> though I've never done 9600 baud packet, or any packet on 440 for that matter
[00:48] <zzqa> so don't take my word for it
[00:50] <aadamson> lz1dev, that's a formal *holding pattern* and you can fly them just as accurate on a timer and headings, usually one leg, (normally the inbound one) will have a nav aid with facilities to help you keep the constant track
[00:50] <aadamson> now a days, you fly those on GPS
[00:50] <aadamson> and if you are lucky you have an autopilot that will *slave* to the gps
[00:51] <kc2pit_> UHF packet would actually be kinda useful for in-flight downlinking experiment data, but we've got a couple 500mW CC1101/CC1190 modules handy for that, and their demodulators are waaaay more efficient than a TNC behind an FM demod.
[00:51] <aadamson> you get them all the time on approaches to land where weather sux, and there is lots of traffic trying to land
[00:52] <lz1dev> aadamson: btw the aprs overlay is live
[00:52] <aadamson> ah. cool, I'll go look at what kinda of monster you've created... MT right?
[00:52] <lz1dev> i'd like to naively think that those circles are done by an autopilot
[00:53] <lz1dev> but who knows
[00:53] <lz1dev> yes mt
[00:53] <aadamson> with a good pilot, you wouldn't be able to tell the diff with AP or hand flying... :)

[01:39] <cipher_> what can reduce the swinging of the payload?
[01:46] <SpeedEvil> cipher_: more length of string
[01:46] <SpeedEvil> If the period is 30s, it may not be an issue
[01:48] <cipher_> I guess 4 meters notlong enough?
[01:50] <cipher_> OK. What about the payload rotating like crazy? Any ideas about that?
[01:55] <lz1dev> something like this
[01:55] <lz1dev> http://image.dhgate.com/albu_243857383_00-1.0x0/universal-rotating-hook-for-pet-leash-or.jpg
[01:57] <cipher_> cool :)
[01:58] <cipher_> though wouldnt it also make it rotate longer once it started rotating in on side?
[01:58] <cipher_> (wind)
[02:00] <lz1dev> if there is low enough friction it could rotate even more :)
[02:01] <lz1dev> but you can add a fin somewhere
[02:01] <lz1dev> and use the wind to stabilize
[02:01] <lz1dev> that might work
[02:08] cipher_ (5b67194a@gateway/web/freenode/ip.91.103.25.74) left irc: Ping timeout: 246 seconds
[02:17] <SpeedEvil> there is no relative wind at a balloon (ideally)
[02:19] <kc2pit_> Practically, there's often some and in erratic directions. So a fin won't give you a preferred direction, but it can provide some damping. Less of it in thin air.
[02:21] <kc2pit_> Anybody ever try magnetic attitude control?
[02:23] <joeman2> small little co2 canistors?
[02:23] <joeman2> thrusters?
[02:23] <joeman2> like the ones used to blow up bikes...emergency inflation
[02:26] <SpeedEvil> magnetorquers
[02:26] <SpeedEvil> especially good for rigid balloons - loop of wire round the envelope
[02:27] <kc2pit_> joeman2: Nah, screw cold gas thrusters. Peroxide and catalysts!
[02:27] <kc2pit_> Because no HAB launch is complete without hazmat handling procedures.
[02:30] <SpeedEvil> hydrazine/umdh is clearly superior
[02:36] <joeman2> :)
[02:36] <joeman2> and corrisive :)
[02:40] <kc2pit_> N2O4? That ain't corrosive. A bit tangy, perhaps. THIS is corrosive, not to mention a spectatular oxidizer for your thrusters: http://pipeline.corante.com/archives/2008/02/26/sand_wont_save_you_this_time.php
[02:41] <joeman2> N2H4?

[02:42] <kc2pit_> Oh, wait. He just said hydrazine, not hydrazine and tetroxide. I guess we were still talking monopropellants.
[02:43] <kc2pit_> I didn't even think hydrazine was corrosive. Nice and carcinogenic though.
[02:43] <joeman2> yeah, perhaps just a nasty thing :)
[02:43] <joeman2> I think they used it in the lift-off from the moon (1969)
[02:44] <N2NXZ> <kc2pit_>Your not too far from me
[02:45] <kc2pit_> Yeah, with N2O4. Everything after the S-IVB ran on hydrazine (or hydrazine/UDMH mixture, I forget which) burning with N2O4. SPS, LM descent, LM ascent, RCS, all of it.
[02:45] <kc2pit_> N2NXZ: Indeed. Haven't been over Rochesterward in a while, though.
[02:46] <N2NXZ> Me neither,my QRZ address needs changing
[02:46] <N2NXZ> In Hilton,NY...but farther away from homocides
[02:46] <N2NXZ> :)
[02:48] <N2NXZ> I was just hanging here a bit grasping the hope for news on possible signals heard for N2NXZ-7,but looks like everyone went to bed.

[02:51] <zzqa> kc2pit: I ordered a few of each, fingers crossed that they don't take until I forget about them to show up
[02:51] <kc2pit_> I haven't been following the channel for a while. What's the short version of the story on N2NXZ-7?
[02:53] <N2NXZ> We launch a 1600g with 434mhz tracker.It did not go very high and I think many gave up on it...lol
[02:53] <kc2pit_> Ahh.
[02:54] <N2NXZ> It should be still running as we speak...untim 10am tomorrow too
[02:54] <N2NXZ> We lost it over watertown,ny,it was a slow mover and time for shutdown after 7 hours,but resume in 40
[02:55] <N2NXZ> Who knows where it is,could have hit the ground or kept going,no one really knows
[02:55] <N2NXZ> There goes about 400 bucks
[02:56] <kc2pit_> Launched from Hilton?
[02:57] <N2NXZ> Yes,it went NE right over the long area of the lake
[02:57] <N2NXZ> between 10 and 15k
[02:57] <kc2pit_> That's ... gutsy, heading over the lake. I just assume that Murphy takes extra notice when you're over water.
[02:58] <N2NXZ> Was hopeful it would climb at sunrise,but tracker shut down before it made it to the ground trackers in Maine
[02:58] <N2NXZ> I think water help altitude honestly
[02:58] <N2NXZ> Lowered when it reached land
[02:59] <N2NXZ> The goal was to at least make it to the guys in Maine...not sure where it is at this point
[03:00] <N2NXZ> Here is the payload > http://i430.photobucket.com/albums/qq22/N2NXZ/VHF%20UHF%20tracking/Balloon%20launch%20September%205th%202014/IMG_9731_zpsaee39bcd.jpg
[03:02] <N2NXZ> Had a close call,I made an error when releasing it in the wrong area,the very bottom of the 30m antenna snagged a tree,but lucky the balloon was not involved
[03:02] <kc2pit_> Did you have any trouble getting helium? UB Nanosat is planning a couple of flights, hopefully this fall, and we're wondering how hard that's going to be.
[03:03] <N2NXZ> Sometimes it is difficult.Last year they told us there was a helium shortage,but found a good place to get some reasonably priced
[03:03] <kc2pit_> When we asked Praxair last year, the answer was "hell no," but we had enough on hand for one flight.
[03:04] <N2NXZ> Helium can be the hardest part of a flight,next to finding trackers to listen
[03:04] <N2NXZ> Think I am going with APRS for now on
[03:04] <kc2pit_> Yeah, we're not trying for really long distances or ultra-light weight, so we're okay with APRS.
[03:05] <N2NXZ> Long flights are near impossible,needs major coordination from a lot of people
[03:05] <kc2pit_> Yep. And we're flying stuff that we really want to recover.
[03:05] <N2NXZ> When are you launching?
[03:05] <N2NXZ> I will be happy to help track if you need
[03:06] <N2NXZ> I know how painful it is to lose stuff
[03:06] <kc2pit_> When the raspi talks to the HackRF and successfully logs noise levels, plus a few days for duct taping the rest together.
[03:08] <kc2pit_> Or when our new satellite radio shows up and the software team says they're ready for a shakedown of the comm system. That will probably be later. May not happen before winter makes flight impractical.

[03:15] <MLow> winter is the only time i want to launch with all the leafy trees here
[03:15] <MLow> for tracking and recovery reasons
[03:15] <N2NXZ> My email good on qrz.com,drop me a note when you are ready to launch
[03:15] <kc2pit_> Hmm.
[03:16] <N2NXZ> Winter would be tough
[03:17] <N2NXZ> I had to climb the pine tree at least 50 ft Friday night to unsnag the balloon...
[03:17] <kc2pit_> I wouldn't want to be sealing up the payload and handling the plumbing in the cold, but that's a temporary unpleasantness.
[03:17] <N2NXZ> Trees can be terrible
[03:17] <MLow> you recovered -7 ?
[03:18] <kc2pit_> Our last (and my first) payload only ended up about 30' up. Was recoverable with a 10' pruning clipper and some creative climbing.
[03:18] <N2NXZ> No,the goal was float as far as possible,it really did not reach a great altitude,but seems many lost interest in it
[03:18] <N2NXZ> It would be still transmiiter as we speak
[03:18] <N2NXZ> transmitting....until 10am tomorrow morning
[03:19] <N2NXZ> I seemed to have lost ground listeners...or maybe some out there somewhere should it find itself to a receiving station

[07:28] <cipher_> if I set the ascent and descend speed, the launch altitude, burst altitude, launch tim and date all correctly, how off can the prediction on the site be compared to the result?
[07:28] <cipher_> (from your personal experiences or knowledge of how it works)
[07:28] <MLow> 10-100km
[07:28] <daveake> It varies, a lot.
[07:29] <daveake> If it's going a long way then the error is likely to be higeh
[07:29] <daveake> higher
[07:31] <cipher_> I don't remember who told me, its "very accurate"
[07:31] <cipher_> flight distance is 80 km
[07:31] <amell> seems to me weight/necklift thus ascent rate is critical. followed by parachute size.
[07:31] <daveake> 10km is a fair guess then
[07:32] <cipher_> thanks
[07:33] <MLow> if you can somehow match all the parameters of the predictions it is pretty accurate
[07:33] <daveake> Ascent is the biggest factor, then burst alt (balloons vary) or parachute size. Depends on the upper winds - if those are strong (as they are in the winter) then the burst alt will probably be a larger factor than the parachute size
[07:33] thasti (~thasti@95.89.11.126) left irc: Ping timeout: 264 seconds
[07:34] <daveake> In the summer the upper winds may be very slow, in which case the burst alt won't make any difference
[07:34] <cipher_> OK
[07:34] <number10> as well as ensuring neck lift is measured accurately which is difficult when windy, running the predictor just before launch helps -
[07:34] <daveake> yup
[07:35] <cipher_> also, can someone explain how different the upper winds are compared to "lower"? It was very windy yersterday but today there's almost no wind, but the predictor shows less distance if launched today
[07:36] <cipher_> *yesterday
[07:36] <daveake> Also, you can judge the likely accuiracy of the prediction by running a new prediction every day or even every 6 hours when the new data comes in. If the prediction changes a lot each time then you can't really trust the last prediction that much
[07:36] <amell> the prediction yesterday changed quite a bit in the space of 12 hours.
[07:36] <fsphil> the air moves in layers
[07:36] <fsphil> *can move
[07:37] <fsphil> in different directions depending on altitude
[07:37] <fsphil> sometimes in opposite directions
[07:37] <cipher_> ok
[07:37] <daveake> I remember one of Upu's - it went west and basically did a 180 over Bristol
[07:38] <daveake> Amazing to watch it follow the prediction so well
[07:38] <pd7r> Good morning

[12:27] <mfa298> would probably make sense to have a habhub ppa or even see if it can be managed by a group of people rather than relying on a single person
[12:27] <costyn_> hey guys
[12:27] <costyn_> whats going on
[12:30] <MaXimaN> costyn_: The Duchess of Cambridge is expecting another baby!

[12:35] <costyn_> PE2G: wots this? another web interface? I can't track unfortunately, seeing as I live on the other side of the Atlantic these days

[12:40] <Maxell> So max 5 meters.
[12:40] <costyn_> Maxell: holy crap... what sorcery is Leo using?
[12:40] <Maxell> DutchMillbt had some spare Aircell 7 coax
[12:41] <mfa298> I think most have been a bit further north than you but he might manage to get one a bit more southerly (they've crossed the atlantic the wrong way around (going accross Europe, Asia and the pacific first)
[12:41] <costyn_> mfa298: thats nuts
[12:41] <Maxell> costyn_: magnets
[12:41] <costyn_> mfa298: how is he getting them to float that long? special balloons?

[18:34] <kc2pit_> kf7fer: Some of us might be interested in those bugs, and possibly helping to solve them. I'm on a university cubesat team; we're setting up to run a couple HAB test flights, and we're building a less clunky replacement for the Byonics MicroTrak that we flew last time. One of our guys has already started laying out a board with an ATmega328 and an SA818, and is working on wedging WhereAVR-style receive code into trackuino.
[18:34] <kc2pit_> So if we're headed for any minefields, it might be nice to know.
[18:35] <kf7fer> kc2pit_: Well, I can tell you that it will work out of the box with Trackuino 1.5 and a 328. Does that help?
[18:35] <kc2pit_> A little, yeah.
[18:36] <kc2pit_> Not exploding on the first try is always nice.
[18:36] <kf7fer> The issues I'm having appear to be related to the 32u4 port of Trackuino; basically I'm only seeing about 91% of the packets I transmit get decoded
[18:37] <kf7fer> But the 328/SA818 board I had made works perfectly
[18:37] <kc2pit_> Huh.
[18:37] <kf7fer> So far, the only real suggestions I can make are to make sure to use a mosfet/transistor on PTT
[18:38] <kf7fer> and I'm running at 3.3v as well, not 5v
[18:38] <kf7fer> NiceRF says PTT draws 60mA
[18:39] <kf7fer> Board is poorly documented and while the support staff means well... they have been hard to get details from
[18:40] <kf7fer> While I'm on a roll...
[18:40] <kf7fer> I hate having to use a UART to configure the board
[18:41] <kc2pit_> 60mA on PTT? WTF? Okay, MOSFET it is.
[18:41] <kf7fer> and there are only commands to SET the configuration, nothing to read it
[18:41] <kf7fer> luckily I did an NPN on my first board out of habit since the docs show it connected directly to a micro-controller I/O pin
[18:41] <kc2pit_> Yeah, I figured we'd set that on the ground once.
[18:41] <kf7fer> once set that's all you need
[18:42] <kf7fer> and don't forget to set the frequency with 4 decimal digits (such as "144.3900") otherwise it will fail with a generic message
[18:43] <kc2pit_> I've got a perl config script from a friend who started using them as foxhunt transmitters.
[18:44] <kf7fer> cool! I haven't done anything with configuration because my first 32u4/SA818 board wasn't able to talk to the SA818 UART (due to limitations on SoftwareSerial)

[18:55] <kf7fer> My first working tracker anyways - I did a test board first
[18:55] <kf7fer> the AA battery module has a TI TPS61202 boost converter on it
[18:56] <kf7fer> of course I didn't get a pic of the backside; it was fuzzy
[18:57] <kf7fer> The wire-wrap wires are for the SA818 UART, power/ground and the ENABLE pin (so I could control it remotely)
[18:58] <kf7fer> zzqa: let me know how it goes. I was going to get a 70cm module as soon as I get the 2m version working. I want to do a cross-band repeater with them
[18:59] <kc2pit_> I've been wondering about the possibility of a balloon repeater. There are standard uncoordinated repeater freqs, right?
[18:59] <aadamson> yes, low power ones
[18:59] <aadamson> look at the bandplan for your region
[19:00] <aadamson> most have them as common I believe
[19:00] <aadamson> doing cross band, you won't need a duplexor
[19:00] <aadamson> may not in same band either depending on antenna placement, etc
[19:00] <kf7fer> aadamson - that was sort of my thought. Just trying to keep the weight down

[19:16] <kf7fer> So it's really as simple as using a SPV1040 and something like the TPS62290?
[19:17] <aadamson> that's what I use
[19:17] <aadamson> reference design for both
[19:17] <kf7fer> so does it handle over-charging and all that?
[19:17] <aadamson> yeah the spv does
[19:18] <kf7fer> ah, ok. So basically something like the MCP73831 isn't needed then
[19:18] <aadamson> you set a VD on it's sens and it will drop basically maintain voltage at that level

[20:29] <Scott85> fsphil, yes it does
[20:29] <craag_philcrump> lilafisch: I've been surprised how well gps works near to the Pi. Had real issues with ~50MHz arm dev boards jamming it.
[20:29] <fsphil> Scott85: that'll be it. software serial is a CPU hog - it'll mess with timing
[20:30] <Scott85> ah right
[20:30] <Scott85> do you think it's better to use hardware serial instead then?

[20:32] <kc2pit_> kf7fer, zzqa: that SA818/828 config script: http://yagi.h-net.msu.edu/cfgsa828
[20:33] <kc2pit_> It looks to match the SA828's ID string, so change that for the 818s.
[20:33] <kc2pit_> I belive they use the same config structure, since I think the 828 is the 818 with some extra bits tacked on.

[20:35] <MLow> how often does it tx?
[20:36] <kf7fer> kc2pit_: That's pretty ugly looking code. I guess I don't appreciate perl. I do like line feeds and one statement per line though ;-)
[20:37] <kc2pit_> Heh. I don't know a damn thing about perl, so neither thank nor blame me.
[20:37] <sp6ryd> SP9UOB-Tom: Hi :)
[20:38] <kf7fer> kc2pit_: Fair enough. Just to add to the fun, to configure the SA818 I just connected a 3.3v FTDI board to it's UART and then gave the commands:
[20:38] <kf7fer> AT+DMOCONNECT
[20:38] <kf7fer> AT+DMOSETGROUP=0,144.3900,144.3900,0000,4,0000
[20:38] <kf7fer> Sorry I didn't record the response from the connect command, it's in the docs though
[20:39] <kf7fer> the SA828 stuff is totally different though
[20:39] <kf7fer> I own both
[20:39] <kf7fer> :-)
[20:39] <kf7fer> for example, for the SA828 I gave the command:
[20:39] <kc2pit_> Yeah, I doubt many of us need to go beyond 144.39.
[20:39] <kf7fer> AAFA3144.3900,144.3900,140.3900,140.3900,141.3900,141.3900,142.3900,142.3900,143.3900,143.3900,145.3900,145.3900,146.3900,146.3900,147.3900,147.3900,148.3900,148.3900,149.3900,149.3900,150.3900,150.3900,151.3900,151.3900,152.3900,152.3900,153.3900,153.3900,154.3900,154.3900,155.3900,155.3900,000,000,0

[20:42] <kf7fer> but I do question the ability for any script used on the SA828 - I'd bet money it won't work at all on the SA818. Did you see the differences in the commands I gave?
[20:44] <kf7fer> oh yeah... am I the only person who didn't notice the pinout of the SA818 in the docs is a view from the bottom and not the top? I wasted $9 and 2 weeks to find that out
