[13:41] <cuddykid> he's building a big (2m) one atm for use in strong winds
[13:41] <Laurenceb_> sewn wing?
[13:41] <cuddykid> he hopes to do some initial testing may time
[13:42] <cuddykid> I think so
[13:42] <cuddykid> fully steerable - rudder and elevator
[13:42] Nick change: navrac_ -> navrac
[13:42] <Laurenceb_> huh
[13:42] <Laurenceb_> you mean a rogallo then?
[13:42] <cuddykid> I don't know how that works either :/
[13:43] <cuddykid> hmm - I'll probe for more details :P
[13:43] <cuddykid> I think it's going to be somewhere between a rogallo and paraglider
[13:43] <cuddykid> according to him it should be able to handle about 2kg some weight should be fine

[13:56] <cuddykid> next issue is how exactly I get the APM to control a bloody paraglider type thing!
[13:57] <Laurenceb_> give up?
[13:57] <Laurenceb_> id go with something simpler

[13:58] <Laurenceb_> you only want yaw control
[13:58] <Laurenceb_> the advantage you have now is that 3 axis compasses are avaliable
[13:58] <Laurenceb_> wasnt the case when i built mine
[14:00] <cuddykid> that might be a solution
[14:00] <cuddykid> Laurenceb_: are you still working on yours?
[14:00] <Laurenceb_> nope
[14:00] <Laurenceb_> ive been working on a custom autopilot board
[14:00] <Laurenceb_> but been busy with work atm
[14:01] <Laurenceb_> i could get you one of my board spopulated for your project
[14:02] <Laurenceb_> but i dont know if its be sensible...
[14:02] <Laurenceb_> id go for something simpler, maybe magno, accel and a yaw gyro
[14:03] <Laurenceb_> then use a complimentary filter to correct heading
[14:03] <cuddykid> yep
[14:03] <cuddykid> I think simple is probably the way forward
[14:03] <Laurenceb_> use accel and magno for tilt corrected heading
[14:04] <Laurenceb_> i used recorded windspeed and gps velocity to do the same thing
[14:05] <Laurenceb_> and a basic kalman filter to work out heading and gyro bias
[14:06] <Laurenceb_> mine was vulnerable to inaccurate wind vector
[14:06] <Laurenceb_> so using a tilt corrected compass could improve things
[14:07] <Laurenceb_> but you can still use recorded wind during the ascent to do optimal route planning
[14:08] <Laurenceb_> i ran landing spot prediction in reverse every 30 seconds or so, starting from the target and going upwards to the present altitude
[14:08] <Laurenceb_> then used atan2 on the resulting location in North,East,Down coordinated to gte target heading
[14:11] <Laurenceb_> alternatively just aim at the target, but the algorithm i described is optimal

[19:33] <jcoxon> shame about the weather - would have been up for a launch
[19:33] <Bob_G8NSV> the GPS antenna works great!!
[19:33] <fsphil-laptop> bad weather there? it's glorious here this-evening
[19:33] <jcoxon> its foul
[19:33] <Bob_G8NSV> horrid here as well
[19:34] <fsphil-laptop> ah, strange that it's so different only a few hundred miles apart
[19:34] <jcoxon> and its going to continue tomorrow
[19:34] <Bob_G8NSV> worse tom i think
[19:34] <jcoxon> i've got this pico payload all ready to go
[19:35] <Dan-K2VOL> hot dog all
[19:35] <Dan-K2VOL> I have sucessfully added timeouts to the Arduino Wire library!
[19:35] <jcoxon> Dan-K2VOL, good work
[19:35] <jcoxon> thats been lacking for a long while
[19:36] <Dan-K2VOL> indeed, I don't think arduino people will incorporate it, but I'm puttin it on github
[19:36] <Morseman> Bob_G8NSV Hi Bob
[19:37] <Bob_G8NSV> the QFH works great
[19:37] <Dan-K2VOL> It finally solved my I2C freezup problem on SpeedBall!
[19:37] <jcoxon> Dan-K2VOL, hooray
[19:37] <jcoxon> so when are you launching ?
[19:37] <fsphil-laptop> ooh nice Dan-K2VOL. I'm beating my head against i2c now. it's horrible
[19:37] <Dan-K2VOL> shooting for May 12
[19:38] <Dan-K2VOL> fsphil-laptop haha I agree, what are you doing with it
[19:38] <fsphil-laptop> just talking to a bmp085
[19:38] <fsphil-laptop> it just seems impossible to write the code in a nice way
[19:39] <Randomskk> yea...
[19:39] <Randomskk> I did this:
[19:39] <Randomskk> https://github.com/adamgreig/spurtalert/blob/master/spurtalert.ino#L293-398
[19:39] <Randomskk> but that bmp_calc_pressure function is just lol
[19:40] <Randomskk> here be dragons
[19:40] <Randomskk> it does work, though.
[19:40] <fsphil-laptop> I'm not using the wire library. probably should
[19:40] <Randomskk> lot easier. then again see ^ discussion about lockups if it freezes
[19:40] <Randomskk> this isn't on a hab so I'm not that fussed
[19:40] <Randomskk> (on the other hand it has months of uptime without freezing)
[19:41] <Randomskk> (which is a lot more than most habs ;))
[19:41] <fsphil-laptop> yea. I'll have timeouts on this thing
[19:41] <fsphil-laptop> although that may slow it down a bit, but for all it's doing
[19:41] <navrac> evening gentlemen
[19:42] <fsphil-laptop> hullo mr.rac
[19:42] <Bob_G8NSV> hi navrac
[19:43] <fsphil-laptop> I noticed the 'mb' calibration value isn't actually used anywhere
[19:43] <navrac> hi, lousy launching weather isn't it - I've got a rebuilt ozzie 2 just waiting for some good weather
[19:44] <fsphil-laptop> really nice here. and from what you guys are all saying, I should probably be out enjoying it :)
[19:44] <Bob_G8NSV> excellent1 not getting any this weekend for sure
[19:48] <Morseman> Not had chance to solder the header on the Arduino or make up the lead for the Ublox yet - This wretched Windows 7 machine took half a day just to get it to connect to the company router...
[19:50] <Morseman> Even had to get the internet Co to VPN into it to figure out what was wrong

[20:04] <Bob_G8NSV> the gps antenna prototype, excuse the photos and the build standard but it does work!!
[20:04] <fsphil-laptop> hey that's neat
[20:05] <Randomskk> Bob_G8NSV: have you measured swr?
[20:05] <Bob_G8NSV> the proper ones will have a little pcb at the top
[20:05] <Bob_G8NSV> cant measure vswr nothing to do it with at that freq. seema to work lying on the bround while I took the photo!
[20:06] <Randomskk> fair enough :P be really interesting to see how it compares to e.g. a sarentel
[20:06] <Bob_G8NSV> theres an online jave calculator on the web for them, used that and made some little wooden plugs to form the shape of the loops
[20:08] <Bob_G8NSV> I have a little cheapo chinese patch with a pre amp, the signal level is slightly lower than that but I am sure it has better all round coverage and sees satellites at a lower angle

[20:09] <Bob_G8NSV> where i'm testing it has a 180deg segment of the sky blocked by the house
[20:10] <Bob_G8NSV> The next QFH will be a 434Mhz version for the RFM22, that I can test VSWR on
[20:10] <fsphil-laptop> a QFH on the payload at 434mhz would be interesting
[20:10] <fsphil-laptop> the swinging and spinning should have much less impact
[20:11] <fsphil-laptop> although will likely be crushed on landing :)
[20:11] <Bob_G8NSV> I will knock one up and let someone try it on a payload

[20:13] <Bob_G8NSV> no they have almost 360
[20:13] <Bob_G8NSV> closest to a true omni you can get apparently
[20:14] <Bob_G8NSV> the plot of them is like a ball with a slight flat at the base
[20:15] <SpeedEvil> ah
[20:15] <SpeedEvil> http://en.wikipedia.org/wiki/Hairy_ball_theorem
[20:15] <fsphil-laptop> lower gain than a 1/4 wave, but we can increase the power going to it
[20:16] <Bob_G8NSV> for a tx antenna if you dangle it "upside down" the flat bit would then point up, but its not much of a "flat"

[20:16] <Bob_G8NSV> plenty spare power in an RFM 22 to bring the ERP back to the limit
[20:16] <fsphil-laptop> actually if it's not too large then it could be built into the box
[20:17] <fsphil-laptop> although it probably will be fairly big
[20:18] <Bob_G8NSV> 233mm high and 101mm dia roughly Play around here!! http://jcoppens.com/ant/qfh/calc.en.php
[20:20] <Bob_G8NSV> I thought of using a bit of plastic sheet (like old fashined OHP transparency film) rolled into a tube and glued up as a support for the wire loops on a UHF version
[20:22] <fsphil-laptop> that's quite big
[20:22] <Bob_G8NSV> just popping out for a bit will be back later, off to the Legion for a beer!!
[20:22] <fsphil-laptop> yay
[20:22] <SpeedEvil> Bob_G8NSV: That's damn near a 2l coke bottle
[20:23] <SpeedEvil> Also - I note that coke bottles can be easily heatshrunk
