[11:05] ..and it's only$125 - I might buy it if I start using it a little more. [11:06] eagle is $125? [11:06] there'll be f/oss options for less [11:06] generally what I try to use, the university appreciate it. 7 [11:08] Yeah - $125 if your working on stuff thats not for profit... in other words - as soon as whatever it is you work on makes money - you have to buy it :-) [11:09] Action: hibby does what he normally does then and pulls out the academic card [11:10] "look at what the cool things this program y'all wrote is doing :)" [11:10] Ok, so just don't make a profit when you release £100 worth of He and burst a £50ish balloon and you're good right? :-) [11:10] woo it's cold outside!

[11:15] If I use the Lassen iQ GPS module in a balloon, how do I communicate with myself on Earth? [11:16] low power radio [11:17] Is that the cheapest option? [11:17] i'm currently testing one of these http://www.radiometrix.com/content/ntx2 [11:17] and one of these http://www.radiometrix.com/content/nrx2 [11:17] well you could log all the data and read it upon retrieval of the payload, but it's not particularly ideal. [11:18] i've got an ntx 2 kicking about, and another module from RS, and some (really cheap) ones from maplin I might try as a backup/alternate to see how effective they are [11:18] ntx2 + cheap GPS + micro + veroboard + bats. [11:18] Is about the cheapest sane. [11:19] Could I communicate by SMS? [11:19] You can also use phones with brken screens if you want to od that [11:19] SMS is unreliable on the ground (actually lying on the ground) in random orientations. [11:19] it's potentially unlegal to do SMS at altitude [11:19] SMS also may not work above a few hundred meters (or even less) [11:20] The cell-towers are designed as much as possible to put no signal into the air, as it robs them of range. [11:21] Hmmm... What is the cheapest easiest way of precisely communicating with the payload when it's on the ground? [11:21] (when it's landed) [11:22] of the three groups i'm working with, the most impressive is the module they've bought that you stick a SIM card in, text it and it returns you the gps data [11:22] can phone it and hear what's going on too :) [11:22] hibby: Great - if it works. [11:22] m1x10 (m1x10@ppp046176119071.dsl.hol.gr) left irc: Remote host closed the connection [11:23] another group are using a phone with an app that will post the locations onto a map [11:23] jackwardell: For total outlay - a SMS tracker of some form. [11:23] another group (actually) used a rape alarm and the goodwill of the local people [11:23] jackwardell: But that comes with a substantial risk of losing the payload. [11:24] jackwardell: The current tendancy is to chase the balloon - aided by online predictions - in a car. This easily gets you to within a few miles of where it's coming down. [11:24] This means that it's at maybe 1000-2000m altitude at worst. [11:25] 1000-2000m altitude, and typical descent rates mean your search area is only a few hundred meters in diameter. [11:25] Ahhh, see I don't want to lose it. I'm not cashing out and then losing it. So let me get this right, I need a GPS module connected to a radio transmitter? And I need a receiver? [11:25] yes. [11:25] And the radio can easily be picked up from a few hundred meters. [11:25] and a microcontroller to take the gps data and control the radio [11:26] The tracker also means that up to a dozen or so people can assist by turning ont heir radios, and uploading strings they recieve to a central location. [11:26] Thanks guys, now considering I'm no pro at electronics and programming (I'm learning). Is the GPS/radio transmitter easy to programme? [11:26] m1x10 (m1x10@ppp046176119071.dsl.hol.gr) joined #highaltitude. [11:27] there are some really good examples online [11:27] plus it's a fine way to learn about this stuff :) [11:27] jackwardell: Mostr of it can be exhaustively tested on the ground. [11:28] http://spacenear.us/tracker/ [11:28] The radio receiver, how much is that? Are they expensive? [11:28] This is the tracker - everyone who recieves your signal can automatically upload to it [11:29] at the moment, someone is just testing. [11:29] which reminds me, I should be testing the hadie payload shortly so it should appear on the tracker [11:29] radio isn't cheap unfortunately, ebay is the best source. [11:29] assuming the gps works ;) [11:30] However, they do hold their value well, so can be resold if you want. [11:30] I forget the model numbers [11:30] i'm using an nrx2 attached to an arduino mega for receiving. [11:31] radio in, gps out :-) [11:31] TangoAlpha: Many modular receivers are some orders of magnitude less sensitivre/more noisy than a 'proper' radio. [11:31] i will be testing it in the next few days [11:31] So wait, the NTX2 has a range of 500m, surely its hard to track? [11:31] For example, we regularly get 400km+ on some. [11:32] with an ntx2 and a SSB radio. [11:32] i've got it attached to a YAGI [11:32] I think the record is 557. [11:32] jackwardell: only has that range in some situations [11:32] works over a range of 20cm quite nicely, lol [11:32] oops, just measured and it's actually 40cm [11:34] When the balloon is like 20km off the ground, can you still get an estimated Lat,Long&Alt from it? [11:37] even when it's 30km :) [11:41] we've finally settled on the name for our HAB experiments in the university... [11:41] SUNSET: strathclyde uni near space exploration teams [11:42] Great name!

[14:35] then if someone does think to listen then its not problem for them [14:35] also with an xml dl-fldigi will put lat/lon in the right place on the display boxes [14:36] ack, I don't have a sample on this box. you going to be around in an hour or so? [14:36] sure [14:36] don't need a wav [14:36] just the format [14:37] cool. will do that first thing. I have the format, but I'd like a "real" sample string from the payload, which I have on my other machine [14:37] cool cool [14:37] Action: stilldavid needs more dropbox in his life [14:37] don't let me get in the way though [14:37] if you run out of time don't worry [14:37] just with the low power radios the more listeners the better even if its just 1 more person [14:38] it's pretty well put together at this point, just going through checklists and whatnot.

[14:38] W0OTM, none currently [14:38] ok [14:39] stilldavid is going to in 2-3hrs time [14:39] jcoxon, fixed .. just re-seated the vreg .. odd that [14:39] and then there is Pell City HF flight [14:39] NigeyS: good good [14:39] hello [14:39] jcoxon, will draft a note to GPSL... should I tell them to use KI6YMZ for upload? [14:39] is your telem string like the ukhas standard? [14:39] very similar, yes [14:39] Hey Lunar_Lander [14:39] $$KI6YMZ,..... [14:39] hi Shuffty [14:40] jcoxon: exactly [14:40] and hibby NigeyS mattltm [14:40] then yes [14:40] sorry hibby [14:40] I meant to write "hi" [14:40] okay, cool. will report back in <1hr. [14:40] hello jcoxon m1x10 [14:40] hi lunar [14:41] it's not a nice feeling to be grounded [14:41] mail is still anywhere but here [14:43] but i finally have a chance to solder something [14:43] the one ear part of my earphones came off and a very fine copper wire ripped off its original solder spot [14:43] :D [14:44] this should be a soldering task with a low risk of screwing up [14:46] PBH-14 is still transmitting. It is transmitting CW every 10 min. starting at H+04, so next transmission will be at 1454 UTC (if chase crews don't pick it up). I can barely hear it in NC. [14:46] is 430-450MHz a HAM Radio frequency? [14:47] why is the website of PBH so crappy? [14:47] AL0I_Todd, one the ground i assume [14:47] on* [14:47] they have no photos/videos, not even real flight recaps [14:47] I can't get a full telemetry string, but it has to be by now. [14:47] pretty poor for a "semi-professional" thing [14:48] I think they are semi-professional if they're backed by Lockheed [14:51] I wonder when they'll try again [14:51] The HF frequency given by the PBH team is carrier frequency, so tune appropriately for your rig. [14:51] AL0I_Todd, you going to listen out for the Pell City WB8ELK launch? [14:52] Maybe. It's probably a waste of time for me. I'm too close for skip and too far for line-of-sight. [14:52] How far? [14:53] hi fsphil btw [14:53] hiya lunar! [14:53] I'm in NW NC. [14:53] do you agree with the PBH website being crappy? [14:53] It leaves much to be desired. [14:53] it's a bit ... spacious :) [14:54] Lunar_Lander, i've made it so that pbh data is plotted on spacenear.us [14:54] PBH-14 transmitting now [14:54] HF is pretty weird, so it's always worth a try [14:54] cool!

[14:56] ah [14:56] wiki says that it transmits a picture or so [14:56] it's an on/off mode, a bit like morse [14:56] basically yea, it's decoding as an image [14:56] a very narrow continuous image [14:57] ah [14:57] like black pixel/white pixel [14:57] yea [14:57] cool [14:57] but with the ntx2 there'll be two versions, one the negative of the other [14:57] btw that Experiment part in Paul Verhage's book is quite interesting [14:57] ah [15:01] yeah [15:01] do the americans in here know Verhage?

[22:53] without a ground plane? [22:53] Sure, Why not? [22:53] Mine still recived WX sats without a GP. [22:53] why not because I don't know what it neefds [22:54] that's good to hear [22:54] Here is a good, simple build... [22:54] http://www.west.net/~jay/turnstile.html [22:54] A vertical dipole doesn't receive well enough, what does the turnstile give over that? [22:54] Circular polorisation. [22:55] well that will help [22:56] I have no idea how your payload is configured but maybe you could hang a reflector under it? [22:56] About 24" lower that the crosed dipole [22:57] You have to be carefull with using an antenna with too much gain. [22:57] where you able to test everything else? the modem and coax? [22:57] the whole setup must weigh less than 150g as well, which is why we're trying to abvoid ground planes and radials [22:57] yes, coax and modem are just fine [22:57] Tigga (~Tigga@apple3feet.plus.com) left irc: Quit: ChatZilla 0.9.86.1 [Firefox 4.0/20110318052756] [22:57] they receive perfect horizon to horizon using a 5/8 wave whip mag mount on a car [22:57] that Digi provided with the modem [22:58] Dan-K2VOL, how did the j-pole get on?

[22:59] http://ea4eoz.ure.es/tt.html [23:01] I'm just baffled why the 1/4 didn't work .. it should be ideal [23:02] says the turnstile is vertical polarization BTW [23:02] Yes, that is strange. [23:02] sorry fellas I'm just in a bad mood here, this shit isn't rocket science, and it's completely killing our chance to ever get across [23:02] Dan-K2VOL, its circular.

[23:05] http://www.mattltm.co.uk/2010/11/27/simple-stacked-j-pole-for-2m-70cm/ [23:06] The stacked j-pole is great, you can just keep adding sections until you run out of height :) [23:06] looks bizarre [23:06] Works very well. You should have a go using your pole :) [23:07] What freq does Dan's gear use? [23:07] I think my little co-linear does as good a job as I'll need here :) [23:08] 137-138 MHz according to google [23:08] The same as WX sats. [23:09] something tells me the uplink is elsewhere though [23:09] "Uplink power of 5W, frequencies between 148 and 150.05 (189 channels), at 2400 bps" [23:09] http://www.decodesystems.com/orbcomm.html#uplink [23:11] So 1 antenna with 2 diferent freq?

[23:11] yea [23:13] http://www.orbcomm.com/Collateral/Documents/English-US/spec-sheet-qheb.pdf [23:16] Looking at the range of antennas for the orbcomm, there must be a problem with somthing elase in the system. [23:18] possibly rfi [23:18] I mean, they are setting antennas that must work that are 83% efficent compared to a 1/2 wave whip. [23:18] something oscillating on the downlink frequency maybe [23:18] SoSounds like it. [23:19] I wonder if they have tested the whole payload with the orbcomm hooked up to the 5/8 wave.

I'm thinking under 1kg... and a 600g balloon. [23:43] On the ukhas wiki, it states a basic launch can be £200. Is this true? [23:43] I mean how basic can a launch be? [23:43] Mobile phone and a bin bag :) [23:44] Balloon - £35. Camera - £100. GPS - £80 (eBay text gps). Parachute - £20. Hand warmers - £5. [23:44] haha -- yea and that even worked [23:44] technically, is that really all is needed? [23:44] you can probably do without the hand warmer [23:44] and get a much cheaper camera [23:44] Haha ;) [23:45] the helium will be your biggest cost [23:45] Am i missing anything out from there? [23:45] Oh yeah [23:45] helium [23:45] ^Thats the only component I can't figure out a price for. [23:45] And all the loca party shops are clueless when I say I want a tank ;) [23:45] it's an iffy value because you won't know how much you need until you've got a good idea of your payload weight [23:46] ain't they just! [23:46] How much does the payload weight affect the helium amount? [23:46] I love the odd looks you get when you tell then you're only filling one balloon :) [23:46] Hahah :) Oh, and the payload container. [23:46] heaver payload will cause a slower ascent [23:47] but a slower ascent will mean your payload travels a lot further [23:47] Ohh, true. [23:47] living on an island nation that is not ideal :) [23:47] (Btw, what do you think bout this as a payload container - http://www.stormguard.co.uk/products/Others/more_images/TAPCOVER.htm ) [23:47] so you'd use more helium to make it ascend quicker [23:47] made to prevent taps freezing in winter. It seems like the perfect thing. [23:48] More helium would also mean a lower burting alitutde though? [23:48] *bursting altitude. sorry. [23:48] indeed [23:49] Hm. So the lighter the better, ey? [23:49] definitely [23:49] my last payload was 510g [23:49] What do you think about the stormguard tap cover as a container? [23:49] could be good - might be a bit on the small side [23:49] Oh wow, that's light. What did you have in it? I mean, GPS wise and camera. [23:50] basic canon camera, fsa03 gps module and a few circuits and batteries [23:50] all in a polystyrene box [23:51] (16cm by 15cm. Is that small compared to other paloads?) [23:51] tis a bit [23:51] your camera will probably fill that by itself [23:51] How much did our launch cost, fsphil? [23:51] *your [23:52] I mean roughly, sorry if I seemed rude. [23:52] I didn't count it .. but the materials that actually flew where probably about £250 [23:52] but there where also some ground bits, like the radio receiver, antenna and laptop [23:52] Hm, okay. I don't get the GPS module you used though. How'd it work? [23:52] Im used to the eBay ones which yu send a text to and they text back with coordinates [23:53] or SPOT GPS Tracker (expensive >:( ) [23:53] yea spot would be ideal if it had a better gps and was cheaper [23:53] But that looks entirely different [23:53] a lot of flights use a small microcontroller to transmit the position over radio during the flight [23:54] there's a few examples on the wiki -- but I can't copy +paste at the moment [23:54] hburger, This is a very basic payload - http://www.mattltm.co.uk/2011/03/24/habat-test-payload/ [23:54] using a phone or sms might be cheaper but the success rate has not been great [23:55] Arduino board, GPS module and low power transmitter. [23:56] Wow - but it looks so complicated... [23:56] About the success rate with the sms, is it really not that good? I mean, how come? [23:56] taken as a whole it's quite complicated, but each part is actually fairly simple [23:57] odds are you'll land somewhere without a signal :) [23:57] Mobile phone masts are designed to put signal out at ground level. [23:58] hburger, Basic concept of transmitting the data - http://www.mattltm.co.uk/2011/02/18/basic-tracking-transmitter/ [23:58] a radio tracker can be tracked for most of the flight, so even if you loose the signal before it lands you'll know roughtly where it is [23:58] Ah.. I thought something like this seemed too good to be true: [23:58] http://goo.gl/xMbuN [23:58] They aren't. [23:58] They're designed to put out signal at head level. [23:58] lol @ SpeedEvil [23:58] But thats when I'll want the signal - to locate the payload once its on the ground [23:58] There are _lots_ of blind-spots if the reciever is 10cm over the ground, compared to 2m. [23:59] Yes, you are right :0 [23:59] I getcha... [23:59] Especially if the orientation is wierd. [23:59] unless you land in a tree :) [23:59] Haha ;) [23:59] Ahem, yes lol. [23:59] happens more than you'd think :) [23:59] And this gps module using arduino - how much does it cost. Honestly, if I had the budget, of course I'd go for it over sms. [00:00] --- Sun Apr 3 2011
