[05:02] I'm sort-of-not around [05:09] I need help [05:09] I have a 1400G payload [05:10] will a 600g balloon lift it? [05:10] Have you seen the calculator? [05:11] As I understand it, yes, but the burst will be considerably under nominal, and you'll need more helium [05:12] can I tie 2 600g balloons together? [05:12] properly filled [05:14] is 2 600g balloons the same as 1 1200G? [05:15] CUSF has launched dual balloons [05:16] try getting a hold of edmoore [05:20] hmm [05:23] is this site accurate for Kaymount balloons? [05:23] http://ukhas.org.uk/guides:balloon_data [05:23] yes [05:23] ok [05:23] so help me understand how to read it [05:23] im new at this [05:24] 600g has a gross lift of 1720 [05:24] I subtract payload + chute [05:24] ~1500g [05:24] W0OTM, it's easier to use http://www.srcf.ucam.org/~cuspaceflight/calc/ [05:25] ok, what do I put in for Target Ascent Rate? [05:25] 1? [05:25] 5 m/s is good [05:25] and delete target burst altitude [05:25] with a 600g balloon [05:25] and 1500g payload [05:25] yeah [05:26] Burst Altitude: 24950 m [05:26] i am getting Burst Altitude: 24950 m [05:26] Time to Burst: 75 min [05:26] you can go for slower ascent rate (if you can afford it) [05:26] and then it will go higher [05:26] what do you mean afford it? [05:26] well, it will travel further (depending on winds) [05:26] oh, ok [05:26] if you have enough land, that's fine :) [05:26] hold on [05:27] use the predictor to check where it will go http://www.habhub.org/predict/ [05:27] http://www.habhub.org/predict/#!/uuid=d8ad7d7d28d09f1e7f123e818c9b71a39c4740a1 [05:27] oh, you already go it, neat :) [05:28] if I use less helium, ill get a lower ascent rate [05:28] will I also go higher? [05:28] yep [05:28] so 600g WILL lift 1500g [05:28] indeed [05:28] is that because is less than the gross lift of 1720? [05:29] 600g will NEVER lift more then 1720g? [05:30] no, it can [05:31] burst diameter is ~602 cm for that balloon [05:31] ok, so as long as I am less than 1720, my balloon will go up [05:31] :) [05:31] so you could calculate how much lift that would get you at sea level [05:31] of course it will burst very quickly if you fill it that much :) [05:32] ok, so I shouldn't freak out that I have 1500g payload [05:32] nope [05:32] you could even launch 2kg no problem [05:33] with 600g balloon? [05:33] thats more than 1720 though [05:33] burst altitude would be 25441 m with ascent rate of 4.2m/s [05:33] W0OTM, that's the "recommended" gross lift [05:34] ahh, ok [05:34] just use the calculator to see what you get [05:34] there's also http://ukhas.org.uk/_media/guides:burst1a.xls?id=guides%3Aballoon_data&cache=cache [05:34] an excel table, that you could use [05:34] it will show gross lift, etc [05:34] I saw that [05:34] if you are interested [05:35] so I put in 4000g [05:35] kk [05:35] Burst Altitude: 22542 m [05:35] Ascent Rate: 3.04 m/s [05:35] yep, slow ascent rate [05:35] Burst Altitude: 20504 m [05:35] Ascent Rate: 5.38 m/s [05:37] I think I get it now [05:37] thank you [05:37] np [05:38] so when I fill this balloon, its should really pull [05:38] its not like a hand full of party balloons [05:38] see the "Neck Lift" field? [05:38] that's how much it should pull [05:38] you can use a scale [05:39] or a bag filled with ballast to test the pull while filling [05:39] ahh [05:40] ok [05:40] Neck Lift: 1986 g [05:40] so I need to put 1986b of weight when im filling [05:40] yep [05:41] when it just starts to lift 1986, I will get the calculated ascent rate [05:41] ? [05:41] exactly [05:41] ok [05:41] I get it [05:41] just be careful if it's windy [05:41] balloon tends to act like a kite [05:44] what alt does the sky turn black> [05:44] ' [05:45] 0m [05:45] at night [05:45] lolol [05:45] you know what I mean [05:45] :) [05:45] W0OTM, 20km or so [05:45] ok, so ill get some nice photos at 27608m [05:46] yeah, you'll have a blast :) [05:46] have you seen my ballon site? [05:46] nope, link? [05:46] http://www.w0otm.com/iHAB [05:47] I got the 20M qrp xmtr done today [05:47] I need to post some new photos of the paayload [05:48] cool, looks good [05:48] when are you planning to launch?

[05:49] i will try to follow it :) [05:49] 1500z [05:49] list on 14.066.7 [05:49] nice camera, should get good quality pics [05:50] are you using energizer lithiums?

[14:29] fsphil: I was planning to buy an HD Hero & shoot 720p 60fps for some nice slow-mo and tons of stills [14:29] why not get a proper video camera? [14:30] also: slow mo is going to be really, really boring for most of it, but super exciting at burst if it's watching the balloon [14:30] if you played it back at 60fps, makes for very smooth video [14:32] I guess that is true [14:33] I'd love for someone to make a 100fps camera [14:35] fsphil, Casio EX-F1 my friend [14:35] hello [14:35] I'm launching a EOS 50D soon witha widangle lense on it [14:35] oh nice [14:35] 50D? [14:36] very nice [14:36] seems like a 450D would do just as well for a fraction of the price [14:36] I wish I had a 50D :P [14:36] let alone to send up [14:36] (that said I am tempted by the prospect of a 1000D for a night launch, with a very fast lens) [14:36] remote triggering isn't hard, they have actual shutter inputs [14:36] and 'manual' mode and sleep properly [14:37] no need for CHDK because they are awesome cameras [14:37] 1000D is about Ł300 though [14:40] could it make usable night shots? [14:40] I think so [14:40] the 50D would be even nicer [14:40] but is a lot more expensive [14:40] once I get paid and if I work for a few more weeks I could afford a 1000D to send up and not be the end of the world if I didnt' find it [14:40] but I can't afford a 50D for personal use, let along to send up [14:40] 1000D with a very fast lens like a 28mm/2.8 would be sweet though [14:40] 28/2.8 is quite cheap, too [14:40] still like three digits though [14:41] lenses are costly [14:41] but, f/2.8 and ISO1600 and the 1000D has much better noise perf than any point and shoot [14:41] yea my big lens for the 350D was almost the price of the camera [14:41] even if it's worse than a 500D or a 50D [14:41] "almost"? [14:41] my lenses are pretty much all more expensive than the body [14:42] at that point I'd be afraid to pick it up, or take it outdoors :) [14:42] :P [14:42] I'm certainly afraid to send it on a balloon [14:43] but a 1000D with a 28mm and f/2.8 lens could get some nice photos I reckon [14:43] and you'd get decent shutter times [14:43] plus as I said you put the camera into manual mode, set it however you want [14:43] in saying that, I had the 350D attached to a 9.25" telescope once -- probably the biggest lens I've ever used :) [14:43] trigger it via a 3.5mm stereo jack cable, they all have shutter inputs [14:43] haha sweet [14:43] yes shutter is great [14:48] I'd rent the lens and body if I were doing that... but get the insurance! [14:49] hehe yes true [14:52] "Sorry, I it's in the north sea somewhere... " [14:53] heck [14:53] "sorry, it's in the north sea at latitude xx.xxxx and longitude yy.yyyyy" :P [14:54] heh [14:55] the UKHAS balloon failure rate must be pretty low these days [14:55] most of the losses have been expected [14:57] haha [14:58] Randomskk: what don't you like about the HD Hero? I'm not crazy about the fisheye lens look, myself. [14:59] rharrison, that EX-F1 is an odd camera - like the high-speed mode though [15:00] The CUSF boys have had a good play with it [15:01] fsphil, check out the wmv's in here http://www.robertharrison.org/images/cutdown/ [15:03] rharrison: were these shot with the EX-F1? [15:03] Yep [15:03] does it produce wmv files, or was that exported from an app?

[22:25] a few people have plans and thoughts [22:26] and prototypes [22:26] but no launches [22:26] I see, thats about how much I have "thoughts" - it seems like CAA aproval might be more tricky [22:26] quite [22:27] I believe the understanding some people came to was that if it was basically a "parachute" that happened to modify its aerofoils to control flight, it'd still count as a payload descending by parachute from a balloon [22:27] and thus be legit [22:28] smealum (~smealum@85-170-63-39.rev.numericable.fr) joined #highaltitude. [22:30] I see :-/ perhaps if I want to attempt a glider flight at some point I'll look to lauch sights abroad where regulation might not be so strict on that point. [22:31] or in international waters [22:31] that's a good point, I hadn't considered that :) [22:32] jcoxon (~jcoxon@nat66.mia.three.co.uk) joined #highaltitude.

[22:41] Can anyone give me information on the suitability / unsuitability of these radio modules? http://www.ok1mjo.com/all/conel/Maxon_ds-dm200-44.pdf I own three of these already, they weigh in a little heavy at just over three quaters of a pound [22:41] annoyingly there was some issues on both flights [22:41] I didn't realise [22:41] yes, last year [22:42] Cool Laurenceb :-) [22:42] second one i demonstrated stable flight [22:42] and some control [22:42] MrCraig: 0.1W would be illegal to broadcast with, on 434 airborne anyway [22:42] but a kont came undone and most of the time it was stuck in a slight turn [22:42] and they're friggin massive and heavy [22:42] *knot [22:42] smea (~smealum@85-170-63-39.rev.numericable.fr) left irc: Ping timeout: 240 seconds [22:42] always the simple things :P [22:42] Laurenceb: D: that's annoying [22:43] what's that RF connector on Robs board called (http://www.robertharrison.org/images/icarus2/IcarusII-Filled.JPG) is it a MCX one ? [22:43] pretty promising though [22:43] seems to have a screw on it which I'd prefer [22:43] but don't know what type it is [22:43] i spoke to some yatch racing guys later and they were like what do you expect to happen [22:43] MrCraig: we use NTX-2s from radiometrix a lot [22:43] You recieve data through a radio tied into a soundcard right? [22:43] apparently nylon line will untie practically any knot after enough vibration [22:44] SMA ? [22:44] yes we use soundcard [22:44] i still have my rogallo - its been upgraded and is ready to fly [22:44] Upu: I think that is an SMA [22:44] I am not 100% sure [22:44] but working on other stuff atm [22:44] I think it is now I look at it [22:44] thanks [22:44] RTF [22:45] also i was going to upgrade the gps to ublox5 or 6 [22:45] before another launch [22:45] I like the nice thick power traces on that [22:45] ok - that could work - I have an old asus eeepc which I loaded windows and bolted a touch screen - planning to bed that in the dash of my car and then I have some dodgy old "spinney tronic" transciever I could tie into it. [22:45] so long as it receives SSB [22:45] MrCraig - look up rogallo wing [22:46] Laurenceb, I did :) [22:46] its the way to do it [22:47] i used a "diy winch servo" and CofG shift [22:47]
