[00:00] I really should have the email notification script wait for like, a minute, then send context around the highlight [00:00] anyway bed [00:20] On the met office weather maps - is the pressure shown for sea level ? [00:20] Should be... [00:21] My pressure sensor is always about 8hPa below that shown by the met office [00:21] I guess it is due to the elevation (about 81m) [00:21] earthshine: what sensor? [00:22] SCP1000 [00:22] hmm ok [00:22] sound wrong? [00:22] is it pre-calibrated and you just read the digital value from the sensor? [00:23] yeah [00:23] using SPI [00:24] should be alright then, unless the calibration is off [00:24] its always 8mb below?

We had our first launch yesterday and it went pretty well. http://animoto.com/play/1tmgAR8C0UcwVHHho99biA [15:13] hi Hualon - congrats :) [15:13] where did you launch from? [15:15] juxta: North Carolina, USA (tracking link: http://bit.ly/ncnearspace-take2) [15:15] good work :) [15:15] Congrats. [15:16] do you have a writeup of the gear used somewhere? [15:16] excellent [15:16] did the spot work throughout the flight? [15:17] I used a spot on my first flight (as a backup), looks like you got better results than I did - the updates from mine were too infrequent [15:17] fsphil: mostly. We lost telemetry (estimating) around 65,000 ft. We got updates about every 10-15 minutes [15:17] juxta: it was handy to track it from the iPhone! [15:18] hehe [15:22] juxta: all we have is the discussion forum we started. http://techshoprdu.com/forum/9 [15:28] Hualon, congrats. Any technical details? [15:29] m1x10: we estimate about 90k feet, 3 hour travel time, just under 4lbs payload [15:33] Howdy [15:34] what about telemetry system? gps? kind of batteries? [15:34] Hualon, looks awesome! i meant to come out and watch but couldn't make it :) [15:35] philihp: Thanks! We had a BLAST. [15:35] any plans for another anytime soon? [15:35] earthshine: howdy! [15:36] m1x10: telemetry was a Spot GPS Personal Tracker. It has a cell-tower assisted GPS beacon mode that relays to the Internet every 10 minutes [15:36] YAY for off-the-shelf components! [15:36] cool, totally off the shelf? [15:41] philihp: for that launch, yes. The first (failed) launch had APRS which failed almost immediately [15:42] that sucks [15:44] do SPOT have a cell gadget? i have the version using Globalstar sattelitte [15:44] philihp: Yeah, we were really disappointed. Not sure what happened to the APRS system. [15:45] LA3QMA: I don't think they do. I misunderstood how it worked before. [15:45] we got what, one packet from the APRS setup? [15:45] ahh ok. have used it on a winter tent trip [15:45] no coverage of anything other than sattelitte [15:45] alikins: yeah, one or two APRS packets [15:46] alikins: what callsign? [15:47] hi LA3QMA [15:47] m1x10: :o) [15:47] hehe [15:47] alikins: We got 3 packets, none of which got igated. :-( [15:47] LA3QMA: We were using the callsign KB4TYE-11 [15:47] lovelace: Yo! Congratulations! [15:47] I'm totally stoked (as you can tell!) [15:48] Hualon: Thanks. :-) Did you see the pictures? [15:48] http://www.flickr.com/photos/clubjuggler/sets/72157624786512244/ [15:48] lovelace: Yeah! Did you see the montage? http://animoto.com/play/1tmgAR8C0UcwVHHho99biA [15:48] Hualon: I did. :-) [15:48] lovelace: I'm working on getting my Spot activated so we can go for launch 3! [15:48] Three is almost taunting. "I'm working. Here's another. And one more, sleep now." [15:48] lovelace: ok most likely the path and how often the beacons are going that "killed" it. or did the tracker stop xmitting? [15:49] LA3QMA: Unknown. It could have been a connection that came loose, or it could have been that the radio was over 30 years old (an Icom 2AT). [15:50] lovelace: 30 isn't so old! (Today's my 30th b-day! LOL) [15:50] That's why I wanted to write "Happy Birthday" on the balloon. LOL! [15:50] ahh ok. balloons always make a hot topic regarding what path to use and how often to send beacon hehe [15:50] Hualon: Congratulations! :-) [15:51] LA3QMA: Yeah, I debated about that. We set the path to WIDE2-2 and to beacon every minute. [15:51] lovelace: Thanks. BTW, I submitted the video, pics, and site to my friends at Make magazine. Hopefully we'll get a blog post about it. [15:51] lovelace: hehe thats an ok setting. it's the WIDE1-1 thats bad [15:51] i would use a switching profile depending on altitude etc [15:52] or just send one packedt with no path and one with WIDE2-2 [15:52] LA3QMA: Thought about that too, but decided to keep it simple. [15:52] simple is always better :o) [15:52] Need to figure out what to do for our next launch. Will probably look for an integrated tracker/radio [15:54] lovelace: Yeah, it would be sweet to have real-time info in addition to the Spot. I like the Spot but it makes me nervous for anything except final recovery [15:54] although it did perform remarkably well for tracking [15:55] Hualon: Indeed. I'm seriously thinking of getting one now too. How much was the one you got? [15:55] hehe does the spot work in high altitude?. do you have the new version? [15:55] LA3QMA: No, it stops above 60k (65k?) [15:55] lovelace: Oh, this one is for the group, you don't need to get one. I paid $40 used and $150 / year for service [15:55] LA3QMA: I have the original version and they report it stops at 60k [15:55] Hualon: Not bad. [15:56] lovelace: I'd really like to take it apart to see if we could make it work more frequently [15:56] BuffaloSouljah (alberto@173-19-94-251.client.mchsi.com) left #highaltitude. [15:56] even if we just hack a button pusher onto the "I'm here" button we could get more frequent updates [15:56] I suppose the simplest answer would be to use two of them [15:56] Hualon: ok i think thats the best version. but the new with better indicators and a "safety" on the 911 button is somewthing i want. but i think the new is not so good on battery and cold [15:57] Hualon: ha! I actually wondered yesterday if the internal GPSr could be replaced with a high altitude version. :-) [15:57] LA3QMA: the old one is heavier too [15:58] Hualon: yes buts that not an issue unless you are sending it up in a balloon ;o) [15:58] I'm amazed at this point that Spot doesn't mention "High Altitude Ballooning" on their list of activities and suggested uses! [15:58] it was -20 in the tent and it worked ok. my radio struggled with the display hehe [15:59] Action: Hualon just shivered a little... -20! [16:00] C or F? (not that it matters much .. still cold either way :) [16:00] hehe it's not bad. when you are skiing you only have a tshirt and some non isolated goretext jacket. -20'C you get warm when moving [16:01] fsphil: first one, then the other. ;-) [16:02] anyhow the spot is nice for the sequrity. but it's a nice gadget too for fun when doing other things [16:02] LA3QMA: With the spot in our 2nd balloon, we were able to get to the landing zone within minutes of it touching down. [16:03] It then too 4 hours to get it out of the tree where it landed (about 60-65 feet up!) [16:03] hehe [16:03] In a tree with poison ivy vines all over it. :-( [16:04] live to close to the sea so in a future balloon i'm going for a cheap tinytrack and a (n)evermore gps [16:04] Yeah, there's something to be said for cheap. [16:06] LA3QMA: tinytrack? [16:06] yes or opentracker APRS thing [16:06] you get them with xmitter too [16:07] juxta (juxta@ppp203-122-193-94.static.internode.on.net) left irc: Ping timeout: 276 seconds [16:08] nothing wrong with this picture: http://www.facebook.com/photo.php?pid=1454779&l=ca95131268&id=742439106 [16:08] when you have view like this: http://www.facebook.com/photo.php?pid=3518354&l=766207fb0e&id=742439106 [16:09] LA3QMA: YO!

[21:05] there's methane though [21:06] I think the issue with hot air as well is that it's friggin cold [21:06] theoretically if the air is hotter than the surrounds it'l just go up [21:06] SpeedEvil (~user@tor/regular/SpeedEvil) joined #highaltitude. [21:06] so it can go as high as anything, just so long as it remains hotter than it? [21:06] but like, it's -40 out [21:07] well yes, but you also need pressure to expand the envelope [21:07] if somebody could build a light balloon containing just vacuum... [21:08] Unless it's internally supported. [21:08] A vacuum balloon is barely doable with good CF [21:08] IIRc [21:08] that would be amusing [21:09] when does it stop going up? [21:10] or rather, does it burst? [21:10] I guess it obviously stops going up when the density differential is no longer sufficient to hold the weight of the thing up [21:10] but it seems like it'd float [21:11] bursting... depends on the structure of the envelope i guess [21:12] Nick change: smelaum -> smealum [21:12] seems like there'd be very little pressure difference at float altitude [21:12] why would it break? [21:12] if it requires the stress from the outside air to hold shape, then it would obviously fail [21:12] CF tends to be pretty rigid though [21:13] it wuld float. [21:13] SpeedEvil: ...forever? [21:13] At the same density of air as its average density. [21:13] Randomskk: pretty much. [21:13] Modulo leaks, and structural failure [21:13] I guess leaks would get you in the end, slowly [21:14] depends how well sealed you were against vacuum [21:14] I have plans for an aluminium balloon. [21:14] and the obvious eventual onset of entropy stopping you doing anything forever [21:14] Superpressure. [21:14] but it sounds like that would be fun [21:14] if you can get it to above the troposphere, it should be quite long-lived.

[21:37] they remove small apertures on the copper and stop, and up the size of apertures on the silk iirc [21:37] but aiui the whole aperture thing is a massive old school carry over right? [21:37] yea [21:38] as noone uses 2 axis optoplotters [21:38] well apart from really small IC masks [21:38] using scanned excimer lasers [21:39] im not sure if they use a raster scanned uv laser to expose the board directly, or some more conventional printer type technique to make a mask for UV exposure [21:40] guess for high volume a mask makes sense... but for proto places [21:40] so evil mad scientist use gEDA [21:40] but their PCB routing is like http://farm2.static.flickr.com/1199/4727511688_2d683e3e5f.jpg [21:40] oh that decides it then [21:41] so? that looks ok [21:41] apart from lack of gnd plane [21:41] and through hole eww [21:42] but yes, they are my main motivation to look at gEDA [21:42] I'm a bit surprised there's no windows build for gEDA or Kicad though [21:42] i guess the issue with "organic" pcb routing is the gerber conversion, thats what i found with batchpcb [21:42] means actually sharing any of my schematics or board files is a non starter for people on windows [21:42] the CAM had issues using sensible apertures [21:42] the get all the weird shapes [21:42] oh, scratch that. kicad is cross platform [21:43] rjharrison (~rharrison@62.49.185.11) joined #highaltitude.
