[04:52] i've been discussing electric motor gliders in another channel, because they are what most interests me right now in personal aviation [04:53] !mes rjharrison_home did you do a launch yesterday (09/09/09)? http://spacenear.us/tracker/ shows a new Icarus track. If that is true, I wish that I'd known as I did a talk about HAB yesterday at http://www.barcampbrighton.org/ and to show a live mission would have been awesome. [04:53] ybit2: this is more a unmanned channel really. [04:53] though of course welcome here - but... [04:54] Electric motor gliders are a hell of a lot less endurance than motorgliders of course. [04:54] Sorry for noise guys! [04:54] somewere I did the sums replacing a stemme S40e with batteries. [04:55] IIRC 1/8th of the endurance. [04:55] hi SpeedEvil [04:56] i like the HK36 Super Dimona [04:57] ..in particular. has there been any previous thought on getting around airport fees? [04:57] that just seems like it would drain my pocket quickly [04:58] http://www.electraflyer.com/ and http://solar-flight.com/ have been my inspiration [05:01] ybit2: [05:01] The second is almost meaningless [05:01] if you want cheap flight [05:02] http://www.electraflyer.com/electraflyerc.php - for example - the batteries will at 1 year be significantly degraded over new. [05:03] And will last probably meaningfully for under 200 flights [05:05] ..before needing replacement, wonder how much the batteries cost [05:07] For 5.6KWh - at least $10K [05:07] probably more like 20 [05:08] It depends if you're willing to go with really cheap cells from ebay :) [05:08] http://www.youtube.com/watch?v=4OsBc8RqSKU forex [05:12] well, that puts things in a more harsh perspective :) [05:13] though more sanely - improperly constructed batteries - or cells within those batteries with defects - can heat, and even catch fire. [05:13] the battery has to be properly constructed to stop that spreading. [05:13] for getting around airport feels, someone mentioned a few aircraft which are capable of being put on a trailer [05:13] This isn't completely trivial. [05:14] "pull off the rear draggy wheel, insert trailer hitch, fold or detach wings, drive off" [05:14] http://groups.google.com/group/rec.aviation.homebuilt/topics - may be of use [05:14] though you probably want to use a sane usenet reader not google groups [05:15] thank you for the link, it will definitely be of use [05:19] Bye guys - got to go to work [05:19] SpikeUK (n=chatzill@host86-139-181-199.range86-139.btcentralplus.com) left irc: "ChatZilla 0.9.85 [Firefox 3.0.13/2009073022]" [05:23] fergusnoble (n=fergusno@fn217.quns.cam.ac.uk) joined #highaltitude.

[17:33] (not the rock) [17:34] : ) [17:35] the temperature sensor on the humidity sensor went down to -40 and bottomed out, as the spec sheet said it would [17:35] the temperature sensor on the pressure sensor went down to -80 and below and then started wigging out [17:35] what's the payload for? [17:36] fun : ) [17:36] I'm just getting the sensor issues settled [17:37] I've got the sparfun weatherboard for humidity, pressure, temp, ambient light [17:37] I'm going to pick up an overo and summit board sometime soon [17:38] the storm case and panel mounting kit have been ordered, same with the barebones computer for the ground station [17:39] my goal is to make a launch vehicle that other people can use to take their experiments up, have remote control and real-time data reporting from [17:40] fun [17:40] Yah [17:40] and expensive [17:40] the storm case and panel kit was 200 bucks [17:45] but my 19" monitor bolts to the lid of it x) [17:46] huh? [17:46] oh - for a ground station. [17:46] yeah [17:46] then I can stuff all the APRS and radiomodem hardware in the bottom part of the case [17:47] I wondered WTF you'd use a monitor on a payload for. [17:47] haha [17:48] I'll just work on this over a year or so [17:48] as funding becomes available [17:56] the radio modems are going to be pretty expensive [17:58] for APRS - guess so [17:58] naw [17:58] oh - you're wanting bidirectional [17:58] yep [17:58] aprs is just for position reporting [17:59] the 500mw transcievers I was using before worked well, but I need to include flow control [18:00] and it cut out a bit [18:00] so this time I'm going to use the 2w versions and a corner antenna [18:00] freq?

[18:13] gah [18:13] ran out of net funding? [18:15] you could use agwpe at the ground station instead of a hardware modem? [18:16] for aprs or remote terminal? [18:17] I already have a kantronics TNC laying around [18:18] well as the modem on the ground, is a ax25 encode/decode via soundcard thing [18:18] oooh yeah, naw [18:18] I don't want to mess with that again [18:18] I tried and failed ;_; [18:18] really y? it worked fine for us [18:19] I had it installed on the gumstix and my desktop, linked by the soundcard, did all the configs, and couldn't ping the other computer [18:20] That would be great if I could get it to work [18:20] what did you guys have set up? [18:20] may find http://wiki.ukhas.org.uk/projects:apex-i useful [18:21] and http://www.hexoc.com/wb/pages/apex-i.php [18:22] well had u managed to listen to traffic from the aprs network? [18:22] were the radios def. transmitting? [18:22] I think we are confused here [18:22] the APRS systems are working fine for me [18:23] yea im not quite sure what u ment ;p [18:23] ok [18:23] but agwpe would be the cheaper option if u got it working [18:24] I am flying a gumstix computer and looking to have a remote serial console [18:24] I did this a year or so ago with some radiometrix transcievers [18:25] and couldnt get it working with agwpe? but the kantronics one works? [18:25] no, I didn't mess with agwpe at all [18:25] I use byonics microtrak 300s and the kantronix [18:26] yea i was suggesting it as a cheap ground station rx'er but u said u couldnt get it working? [18:26] naw, what I couldn't get working was the AX.25 network connection between the gumstix and desktop [18:26] oh [18:27] i cant say we got remote terminal working either [18:27] : ( [18:27] it would be so great [18:27] and soooo much cheaper [18:27] i assume this is running some sorta linux? [18:27] yeah [18:28] OE on the gumstix and suse on the desktop [18:28] we did manage getting two way comms tho [18:28] how? [18:28] with ax.25? [18:28] yea [18:29] ah, cool. [18:29] there was a perl script listening to incomming traffic and decoding it [18:29] oooh ok [18:29] its described on one of the links if u want more info [18:29] ok [18:29] but i didnt do that bit so i dont know exactly how it worked [18:30] once I get the overo system up and running I'll try the ax.25 networking again [18:31] u can try, but we tried for ages and never got it working [18:31] : ( [18:31] I remember it being so close too [18:31] but thers always an alternative which is what we settled for [18:31] yeah [18:31] if jon_APEX were around he would be able to talk in detail [18:32] ok [18:32] we wernt that far off either [18:32] and in the end we didnt use the uplink :p [18:32] aww [18:33] we used ours primarily for telling the gumstix to initiate the cutdown [18:33] yea same [18:33] since trossen has that nice pan tilt interface, its one more thing to control [18:33] yea [18:34] but if its jsut a few things, u could get a perl script to listen for a few commands? [18:34] I'd like a little more flexability than that [18:34] I'll get it working one way or another [18:34] and this was our modem on the balloon http://www.tnc-x.com/ [18:35] ah, ok [18:35] cool [18:35] although back to my orginal point, agwpe is the cheap option to [18:35] TNCs on the ground [18:35] :p [18:35] mhmm [18:36] the 500mw transcievers I used were about 200 a pop [18:36] Ł ? $? [18:36] nice and small, light, and was pretty transparent to the gumsix's serial console [18:36] USD [18:37] its a UK business so it might be cheaper for you all, I dunno [18:37] the UHX1 from radiometrix [18:38] mm [18:38] without flow control you had to type kinda slow so it wasn't sending data while the balloon terminal was echoing what you just typed [18:38] but ti was doable [18:38] even vim worked [18:38] which was slightly orgasmic. [18:38] err [18:38] or get it to not echo? [18:38] er? [18:38] yes, err [18:39] Yeah, but it was like a handshake so I could see that the command went threough [18:39] I was about to continue with a thought - which I have now forgotten [18:39] I think it was along the lines of slip supporting half-duplex links or something [18:40] anyway we;re using the BiM1 which cost us Ł20 (got half price thru the school ;) ) [18:40] aww nice [18:40] in my old group we had nasa funding and money from the space pictures we sold, so we paid full [18:40] yea [18:41] even so a rather large price differnece [18:41] yeah [18:41] i know ur ones are fancer [18:41] fancier [18:41] they include audio in out [18:41] I think the MiM1 has a dumb modem in it [18:41] did it?/ [18:41] biM1 [18:41] *bim1 [18:41] and theu have no modem [18:41] yeah [18:42] ah ok [18:42] i like that part [18:42] just data in one end, audio/data out other [18:42] ok [18:42] we're making our own modems [18:42] Thats neat [18:43] v2 is the cheap version :p [18:44] I just don't have time to mess with the real basic stuff anymore. its so much more rewarding to do stuff like write your own modem and stuff like that : ) [18:44] and I'm a one man show here in TN [18:45] well i think im pretty much the one man on the electronics [18:45] ahh [18:45] but i have nothing to do atm :p [18:45] aww. [18:46] and instead of linux boards, PICs [18:46] so massive price saving there [18:46] yeah [18:46] Matt_APEX: maybe [18:46] Matt_APEX: bifferos.com [18:46] I don't know squat aboutmicrocontrollers : ( [18:47] Had no findings on the original APEX yet have you? [18:47] nope [18:47] and Ł29 aint bad [18:47] still 6x the price of a PIC [18:48] and they are probably easier to program than linux [18:48] much simpler [18:48] well depends on choice of PIC language [18:48] picaxe good starting point [18:49] yes - it's a very different thing. [18:49] But you are going to have considerably more trouble hooking on a USB webcam say on the PIC [18:50] But a simple A/D would be easier on the pic [18:51] yea depends what i want to do [18:51] if u used the linux board we would still have a pic board connected to sensors and other basic i/o things [18:51] PRetty much [18:52] Unless you can live with teh very limited IO - or something like a soundcard for sampling [18:53] it would be nice if there was a board out there that had like, 10 channels or so of ADC at 12b resolution, that just spit out the values in CSV at some interval [18:53] know of anything like that? [18:53] yeah [18:53] I mean - it would be nice [18:53] aww [18:55] if i were u id get a PICAXE and learn how to use it (if u have time) [18:55] they are very simple [18:56] anyway im off for a bit, bye [18:56] later [18:57] s [19:08] Matt_APEX (n=chatzill@87.115.5.69) left irc: Read error: 148 (No route to host) [19:23] natrium42 (n=alexei@CPE000625d867e2-CM0014045885be.cpe.net.cable.rogers.com) joined #highaltitude.

[20:56] I was at a Bar Camp in Brighton - I did a pres about HABs. Seems to have stirred up some interest. Been asked to do similar in Manchester in Nov.

[20:58] I'm in Derbyshire [21:04] Closer than Surrey ;-) Would you be up for a BarCamp in Manchester 7/8th Nov http://bcman2.eventbrite.com/ ?

[21:10] Weybridge, in Surrey. A BarCamp is a sort of freeform conference. Everybody attending should do a 30min presentation or help is some other way. They tend to be fairly geeky, but that's not universal. Good place to start is http://barcamp.org/ [21:10] ah ok [21:13] SpeedEvil (n=user@tor/regular/SpeedEvil) returned to #highaltitude.
