[01:05] <juxta> how's things?
[01:05] <natrium42> good
[01:05] <natrium42> had to supervise an exam today...
[01:05] <juxta> heh
[01:05] <juxta> better than sitting one

[01:08] <natrium42> good stuff
[01:08] <natrium42> how did etching work out?
[01:11] N900evil (~Speedevil@tor/regular/SpeedEvil) left irc: Ping timeout: 245 seconds
[01:23] <juxta> natrium42: really well :)
[01:24] <juxta> first shot at it, couldn't find any magazines, so I used some catalogue that was mailed to me recently
[01:24] <juxta> coincidentally, of electrical gear ;p
[01:24] <natrium42> did you go the UV way or the laser printer way?
[01:24] <juxta> laser printer
[01:25] <juxta> I got the plain copper clad quite cheaply, there's an electronics store here that sells manufacturing surplus
[01:25] <juxta> so they often have some products very cheaply - big inductors etc for a few cents often, and always lots of copper clad
[01:26] <natrium42> ah, nice
[01:26] <juxta> natrium42: here's the back of the board: www.bogaurd.net/IMG_3336.jpg
[01:26] <juxta> the top right got a little messy, a broken track there
[01:26] <juxta> but I think the rest worked out OK
[01:27] <natrium42> yeah, edges look quite clean
[01:27] <juxta> this is what I used to drill it: www.bogaurd.net/IMG_3337.jpg
[01:28] <natrium42> hehe, i have a similar one
[01:28] <natrium42> drill bits are so easy to break...
[01:28] <juxta> hmm
[01:28] <juxta> I havent broken one yet'
[01:28] <natrium42> maybe you're more careful than i
[01:29] <juxta> but they are very thin, so I can see it happening
[01:29] <juxta> the trouble i had was that the dremel can't grip a 0.8mm bit
[01:29] <juxta> smallest it can bite is perhaps 3mm or so
[01:29] <juxta> so I wrapped some electrical tape around the bit to beef it up, seemed to work OK
[01:30] <natrium42> haha, nice hack
[01:30] <juxta> maybe it's because I used a knock-off dremel
[01:30] <juxta> $40 vs $140 for the real deal
[01:30] <juxta> unfortunatley I had to buy a dremel brand press thing, there was no alternative :(
[01:32] <juxta> do you do your own boards often natrium42?
[01:32] <natrium42> not any more, got too lazy
[01:32] <natrium42> now i just order them made
[01:32] <juxta> fair enough
[01:33] <juxta> batchpcb pricing is OK, but shipping kills it for me
[01:33] <natrium42> what about seeedstudio?
[01:33] <juxta> it's almost me worth getting a 100sq panel direct from gold pheonix
[01:33] <juxta> yeah I emailed them
[01:33] <juxta> Hi Terry,
[01:33] <juxta> We are just back from holiday, the Fusion PCB will be available soon.
[01:33] <juxta> Thanks
[01:33] <juxta> Albert
[01:34] <juxta> "
[01:34] <juxta> not too sure what they mean, they never really answered my questions directly, heh
[01:34] <natrium42> oh yeah, the chinese new year thing
[01:35] <juxta> yeah
[01:35] <natrium42> i use https://www.barebonespcb.com/!BB1.asp
[01:36] <natrium42> they ship the next business day and fedex takes 1 day to me
[01:36] <natrium42> <---- really impatient
[01:36] <juxta> yeah
[01:36] <juxta> me too
[01:36] <juxta> they're pricing isnt bad either
[01:37] <natrium42> yep, but their fedex rates are terrible
[01:37] <juxta> damn
[01:37] <juxta> fedex is usually $25 for 2-3 day to me
[01:37] <juxta> from places like sparkfun etc
[01:38] <natrium42> they'll ship via your fedex account though
[01:38] <natrium42> but my rates are not much better
[01:38] <juxta> where are they based?
[01:38] <natrium42> USA somewhere
[01:39] <natrium42> colorado
[01:42] <juxta> I contacted some local places
[01:42] <juxta> for quotes
[01:42] <juxta> ~300 AUD for prototypes was the cheapest I found
[01:42] <natrium42> ouch
[01:42] <juxta> most have a $500 minimum
[01:42] <natrium42> goldphoenix is cheaper
[01:42] <juxta> yeah
[01:43] <juxta> $115 or whatever it is
[01:43] <juxta> quite cheap
[01:43] <natrium42> and you can pay for 24h turnaround :)
[01:43] <juxta> and they'll seperate the panel for you, wont they?
[01:43] <natrium42> yeah, tab routing
[01:43] <juxta> oh really? what's that cost?
[01:43] <natrium42> they say on their site
[01:43] <natrium42> i always get it
[01:43] <juxta> i'll check it out

[01:44] <natrium42> haha
[01:45] <natrium42> they probably had no security
[01:45] <juxta> oh, there's a small padlock over the access cover
[01:45] <juxta> then most signs have a default password

[14:41] <edmoore> 'hi my name is bob. I want to do a balloon flight. can you tell me how to do it?'. We get about 4 of these emails a week and to properly answer the question takes more time than we have. I have just put a notice on our contact page pointing people to the UKHAS wiki before emailing, but how can we make it more obvious that the UKHAS wiki is the place to go to find out more?
[14:41] <edmoore> We should get more people to link to it to drive it up pagerank
[14:42] <edmoore> thoughts?
[14:43] <russss> needs some more text on the front page
[14:43] <russss> I'll give it a go
[14:45] <edmoore> I agree - and keeping the news up to date
[14:45] <edmoore> perahsp we should prompt people to update the UKHAS page after their launches. I will be sure to have a go tomorrow

[14:53] <LazyLeopard> Yep, adding current relevant news to a website is always good.
[14:55] <edmoore> for everyone pinging about the cusf predictor being broken, yes sorry
[14:55] <edmoore> it was always a bit of a bodge
[14:56] <russss> err, dude
[14:56] <edmoore> but it's an excuse to roll the shiny beta version out, or at least a subset of it that is functionally equiv to the old predictor
[14:56] <russss> http://ukhas.org.uk has <meta name="robots" content="noindex,nofollow" />
[14:56] <russss> that would be why it's not turning up on google.

[15:00] <russss> also although it's quite a good idea to have nofollow on wikis, doing it with a meta tag is a bad idea because google won't find any of the other pages on the wiki
[15:00] <russss> sure

[15:03] <djellison> Hi JC
[15:03] <djellison> Very light snow - again - in Leic
[15:04] <jcoxon> its snow/rain right now
[15:05] <jcoxon> so PD3EM is out in the field again
[15:05] <jcoxon> has picked up the beacon again and is beginning to triangulate
[15:05] <russss> slow going I suppose
[15:06] <edmoore> oh wow
[15:06] <edmoore> that's a mighty battery
[15:08] <djellison> What the actual telem on the CW?
[15:08] <djellison> I'm assuming it's not lat/long or he'd have walked up to it by now :0
[15:09] <jcoxon> yeah its purely a beacon
[15:10] <djellison> Should be REASONABLY easy to find with it having a deflated but intact balloon
[15:11] <jcoxon> yeah

[15:34] <jcoxon> BH4 RECOVERED
[15:35] <rjmunro> Wow.
[15:35] <jonsowman> nice one :)
[15:35] <jonsowman> good to hear
[15:35] <rjmunro> Now you just need to reprogram it so that it stops pumping even if there is no GPS signal, and you can launch it again.
[15:35] <djellison> Holy crap :)
[15:35] <jcoxon> rjmunro, hehe, need to sort out why the pump breaks the gps
[15:36] <djellison> Awesome - utterly awesome
[15:36] <russss> diodes
[15:36] <russss> and ferrites
[15:36] <jcoxon> always fly with a backup beacon
[15:36] <rjmunro> If the pump stops, it's not essential that the GPS keeps working while it is actually pumping.
[15:36] <rjmunro> As long as it gets lock again after pumping stops.
[15:36] <russss> and it might be prudent to shut everything nonessential down if you get a GPS lock
[15:36] <russss> or it might not
[15:37] <russss> err. lose.
[15:37] <jcoxon> rjmunro, yeah but it must be possible to have them working together
[15:37] <rjmunro> Of course, if it's an easy fix, then fix it. :-)
[15:37] <jcoxon> glad we picked up on this is now - imagine on a trans-atlantic
[15:37] <rjmunro> jcoxon: It's why you do tests :-)
[15:38] <djellison> I remember HAPS - foxhunting the sodding thing across Norfolk :)
[15:38] <jcoxon> djellison, you can't say that wasn't fun
[15:38] <djellison> Can you give it fake altitude, but real lat-long, to do a more integrated test?
[15:38] <djellison> Oh - I loved it
[15:38] <djellison> Made the images 'taste' better :)
[15:38] <jcoxon> and they were great iamges
[15:39] <jcoxon> images*
[15:39] <rjmunro> What does "Hanging 50cm above water!" mean?
[15:39] <djellison> Those words 'Is it red and blue?' coming through that hedge
[15:39] <rjmunro> (http://twitter.com/geenweer/statuses/9530225169)
[15:42] <djellison> There is a lake/river/pond or other body of water, and by some means the payload has ended up tangles/hung/caught up on some pole/post/tree/bush/hedge causing it to be 50cm above said lake/river/pond
[15:42] <SpeedEvil> tree!
[15:44] <rjmunro> djellison: I don't think you need to give it fake altitude to test. Give it real altitude, it will think it is floating, and will pump.
[15:45] <djellison> You would want to emulate ascent, slowing to float, a dump, then ascent again, then float, then dump.
[15:45] <rjmunro> You could use a car and a hill :-)
[15:45] <jcoxon> i already do that with my fake gps data emulator
[15:45] <djellison> Otherwise it would just dump before you launch the thing and everyone would have ethanol on their shoes
[15:45] <jcoxon> also the code is designed not to dump on the ground of coruse
[15:46] <jcoxon> thats not the issue - the issue is testing the gps with the pump at the same time
[15:46] <jcoxon> just requries turning them both on at the same time
[15:46] <djellison> Point is - if you're emulating the data, the GPS isn't on. What I'm asking is if you can have the GPS on, pull it's lat-long in, so it's actually working, but then emulate the altitude string
[15:46] <djellison> Getting the best fidelity for an integrated test that you can
[15:47] <rjmunro> The problem is that if the GPS is connected in a different way that it would be in a real flight, the noise that was blocking it may not be conducted towards it in the same way.
[15:47] <rjmunro> If that makes sense.
[15:48] <djellison> I'm assuming it's just electro-mag interference of some sort - it'd crap out just the same.
[15:48] <jcoxon> rjmunro, djellison the easist way would be to temporaily remove the part that says that float has to be at altitude
[15:48] <jcoxon> its a single if clause and that part has been well tested
[15:49] <rjmunro> djellison: Not if the electro-mag interference was being conducted / amplified by the way the cables are arranged inside the payload.

[16:44] <fsphil> hi guys, any word on the recovery?
[16:44] <jcoxon> fsphil, its been found
[16:44] <fsphil> fantastic
[16:44] <rjharrison> Cool
[16:45] <MikeMc68> has it been recovered from teh tree yet though?
[16:45] <rjharrison> atlas live to fly another day
[16:45] <edmoore_> wow!
[16:45] <jcoxon> its only 50cm up, hanging over water apparently
[16:45] <jcoxon> thats all i've got - was twittered
[16:45] <jcoxon> so i expect we'll get pics etc in a bit
[16:45] <rjharrison> Lets hope it's not tidal
[16:45] <rjharrison> :)
[16:46] <jcoxon> that atlas flight puter has clocked alot of miles now
[16:46] <jcoxon> 2 crossings of the channel
[16:46] <rjharrison> Show off
[16:46] <fsphil> lol
[16:46] <rjharrison> Now get it across the atlantic
[16:46] <jcoxon> rjharrison, hehe but it always breaks :-p
[16:47] <fsphil> doesn't like being repeatedly dropped from 30km :p
[16:50] <fsphil> your planning to fly it over the atlantic?
[16:51] <H__> found ? that's great news
[16:52] <jcoxon> fsphil, not this payload - the testing of the ballast tanks is in for a trans-atlantic payload we are working on,
[16:52] <jcoxon> they'll be other flights to test other systems in the future

[17:02] <rjharrison> jcoxon, UTUBE?
[17:03] <rjharrison> Did you get permission
[17:03] <jcoxon> rjharrison, for the CW yes - http://www.youtube.com/watch?v=a29h2pZaij8
[17:03] <SpeedEvil> jcoxon: was there any recording of 'stuff'?
[17:04] <SpeedEvil> jcoxon: or was it all only broadcast
[17:04] <jcoxon> it was broadcast only
[17:04] <SpeedEvil> Though actually - that doesn't matter so much.
[17:04] <jcoxon> but i've got a very god log of data from G4FEV
[17:04] <SpeedEvil> Due to the gps being out I suppose
[17:04] <jcoxon> all the temp and light data
[17:06] <rjharrison> humm one of the better video on utube not!
[17:06] <rjharrison> :)
[17:06] <rjharrison> I think the first 5 seconds set the pace
[17:07] <rjharrison> but cool, looking forward to the pics over the dyke
[17:09] <jcoxon> rjharrison, to me its a very exciting video
[17:10] <jcoxon> details of recovery will be posted later on this evening
[17:11] <fsphil> awful weather in the video

[17:38] <rjharrison> hi natrium42
[17:39] <natrium42> hey rob
[17:39] <rjharrison> Your tracker is going to get some more abuse tomorrow
[17:39] <rjharrison> cusf launch
[17:39] <natrium42> hehe, excellent
[17:39] <rjharrison> natrium42 looking good
[17:39] <SpeedEvil> What's the aims?
[17:39] <rjharrison> Up down and flying around
[17:39] <rjharrison> SpeedEvil no idea
[17:39] <natrium42> test uplinking it sounded like
[17:39] <rjharrison> Yep a bit of that I think
[17:40] <natrium42> rjharrison, do you have the listener lat/lng when you are forwarding the positions?
[17:40] <rjharrison> no it's fixed on the client atm
[17:41] <natrium42> mkay
[17:41] <rjharrison> I can post it to you if you like
[17:41] <natrium42> that would be cool
[17:41] <natrium42> i am thinking of highlighting the stations once positions come in
[17:42] <natrium42> and drawing lines to all receivers when you hover over a position (a la aprs.fi)
[17:42] <rjharrison> Humm you have the logger id
[17:42] <natrium42> yep, but not sure what's the best way to get their location
[17:42] <natrium42> i could parse it out of the kml, but that's not perfect
[17:42] <rjharrison> http://www.robertharrison.org/listen/active_rx.php
[17:43] <natrium42> yeah, i am overlaying that one
[17:43] <rjharrison> Like quick script would be good
[17:43] <natrium42> but if you sent the logger location with each update, then the loggers could also be moving vehicles
[17:43] <natrium42> so that would be optimal
[17:43] <natrium42> but maybe we should wait until we do the rewrite
[17:44] <rjharrison> Yep I could see where you were going with this
[17:44] <natrium42> everything is half-assed atm
[17:44] <rjharrison> As good as that
[17:44] <rjharrison> :)
[17:44] <sbasuita> Could we not leverage some aprs protocols/equipment on the unlicensed frequencies?
[17:45] <natrium42> we don't really need to have links between listeners
[17:45] <natrium42> so not sure if the extra complexity is justified
[17:45] <sbasuita> hmm
[17:47] <natrium42> and we don't need hopping either
[17:47] <natrium42> or do we?
[17:47] <natrium42> gprs coverage seems to be ok
[17:50] <sbasuita> yeah it just seems like the whole system is getting fairly advanced so it would make sense to reuse the aprs work
[17:50] <rjharrison> humm
[17:50] <rjharrison> I'm not a big fan of aprs but I'm not a big user of it either

[21:09] <gordonjcp> yay
[21:10] <gordonjcp> so quite comprehensively in PA-land and not so terribly far from where you last heard it?

[21:58] <RocketBoy> looking for somthing more ideal for HABing
[21:59] <RocketBoy> somthing that will give good stability in a low density fast flow environment
[22:00] <fsphil> I remember reading about the problems with chutes for the mars landers, and the low pressure. the chutes kept collapsing
[22:01] <RocketBoy> yeah
[22:03] <fsphil> though they tend to be going a lot faster than these payloads would!
[22:03] <fsphil> how fast do they drop anyway?
[22:03] <fsphil> in the low pressure
[22:04] <rjharrison> Icarus III payload coming together
[22:05] <edmoore> fsphil: on mars or on earth?
[22:05] <RocketBoy> fsphil - say about 300 - 400mph to start - depends on height
[22:05] <RocketBoy> (habing)
[22:05] <fsphil> earth I mean
[22:06] <RocketBoy> fsphil - thats just one of my flights typical values

[22:28] <fsphil> did it spin all the way down?
[22:28] <RocketBoy> quite a while - slowed when the air got ticker

[22:31] <fsphil> is it possible the payload caused the spin?
[22:35] DanielRichman (~DanielRic@unaffiliated/danielrichman) left irc: Remote host closed the connection
[22:35] <RocketBoy> from the footage i imagine the whole chute-payload system spiraling down
[22:37] <RocketBoy> possibly - but I have seen the same on other payloads with that type of chute - its not too bad a thing as long as you can put up with it
[22:38] <RocketBoy> its quite typical for simple chutes - i have seen it alot with model rockets
[22:38] <jcoxon> with the good gps modules you can sometime see the spirally track
[22:38] <fsphil> i thought maybe with the payload disturbing the air first, it might affect the chute in some way to cause the spin
[22:40] <fsphil> need a low pressure wind tunnel :)
[22:41] <RocketBoy> or some test flights :-)
