[09:39] <Upu_2E0UPU> Gypsys cut down the telegraph pole to steal the wire (kid you not) last week. They use a LCR provider it took BT 8 days to get out and fix it which they did yesterday mid afternoon.
[09:40] <Upu_2E0UPU> The gypsy came back at 7.20pm last night and stole it all again. Additionally they decided to rip down the (live) power lines as well.

[10:47] <cuddykid> all stations go
[10:47] <LazyLeopard> The clicks from the electric fence were easy enough to deal with. The static crackles from all manner of odd electrical activity (from thunderstorms to arc-welders) was rather harder to get rid of. Some days I wasn't getting even 50% decodes on PSK31
[10:47] <Upu_2E0UPU> hey
[10:47] <Upu_2E0UPU> thats a good idea, farmer has sheep out at the moment

[11:23] <mixio> yeah, i like to use some official word
[11:23] <mixio> u know
[11:23] <Upu_2E0UPU> the payload box has thermal insulation to protect the flight computer from the adverse effects of the cold

[13:43] <Lunar_Lander> the PWM pins are still the same for instance
[13:43] <Lunar_Lander> and I don't think I mixed up the resistors

[15:00] <cuddykid> got some 40mm diameter pipe from wickes as well with a 90 degree bend, so going to make a filler nossle thing
[15:00] <Dan-K2VOL> great cuddykid!
[15:01] <cuddykid> btw, they lent me one of the regulators where you just push the nozzle in and it lets out helium, so do you just keep it held in for the whole filling?
[15:02] <m1x10> How can I calculate the descent rate using as parameters the weight of payload and the size of the parachute ??????/
[15:03] <BrainDamage> manually, or using a calculator?
[15:03] <m1x10> no matter
[15:03] <m1x10> calculator should do things faster though
[15:03] <BrainDamage> there's probably calculators somewhere, I'd know how to do manually tough :p
[15:05] <Dan-K2VOL> cuddykid, the ones that you use to fill party balloons?
[15:05] <cuddykid> Dan-K2VOL: yeah
[15:05] <Dan-K2VOL> cuddy kid that might take approximately forever to fill the weather balloon :-)
[15:05] <cuddykid> exactly like - http://cgi.ebay.co.uk/HELIUM-BALLOON-INFLATOR-GAS-REGULATOR-FILLING-NOZZLE-/170656893437?pt=UK_Home_Garden_Celebrations_Occasions_ET&hash=item27bbf189fd#ht_500wt_1156
[15:06] <cuddykid> oh no :S
[15:06] <BrainDamage> for manually, get the friction coefficient of the chute and the payload, approximate one doesn't affect eachother
[15:06] <BrainDamage> then balance gravitity pull with air friction, for steady state will work good
[15:06] <Dan-K2VOL> but better than no regulator at all cuddykid
[15:06] <Dan-K2VOL> for safety anywa
[15:06] <Dan-K2VOL> y
[15:06] <BrainDamage> you'll get a trivial differential equation
[15:07] <cuddykid> it has a reasonably widish nozzle (about 1cm) .. well for party balloon anyway.. so hopefully!
[15:07] <cuddykid> then its just hosepipe to the 40mm pipe I've got
[15:07] <Dan-K2VOL> mixio spherachutes.com has a handy weight/descent rate chart for spherical chutes

[15:10] <jgrahamc> Whoops cuddykid, yes I meant mixio
[15:10] <cuddykid> haha no probs
[15:11] <cuddykid> I'm guessing for the balloon inflating, judging by http://ukhas.org.uk/ideas:balloon_filler it doesn't have to be 100% sealed (the filler mechanism)?
[15:13] <Dan-K2VOL> not precisely no, but if there's holes or gaps you'll of course lose a little helium, unless you get some unfortunate geometry that causes bernoulli's effect to suck air in with the helium

[16:55] <Lunar_Lander> it is good that you are here
[16:55] <RocketBoy> - many thanks though - its difficult doing it on your own - so your tracking was a great help - one less thing to worry about when driving

[16:57] <Hiena> ' evening!
[16:57] <RocketBoy> LazyLeopard: u r M0LEP (I guess)
[16:57] Action: LazyLeopard was a bit slow getting tracking; the payload was over 5kms before I caught the first line...
[16:58] <LazyLeopard> RocketBoy: Yep. Though I (briefly) appeared on the tracker as 5Z4/M0LEP; fallout from a recent overseas trip. ;)
[16:58] <RocketBoy> yeah - the 3g coverage at the launch was a bit poor (i was in a dip) - so I couln't get on to let everyone know what was heppening
[16:59] <Upu> I hear beeps Lunar_Lander
[16:59] <Lunar_Lander> yeah
[16:59] <Lunar_Lander> but look at the dlfldigi
[16:59] <Lunar_Lander> there is only one line, not two
[16:59] <LazyLeopard> Still, it's the tail-end tracking that makes the difference re recovery. :)
[16:59] <Upu> whats with the crystal ?
[16:59] <Lunar_Lander> it's not connected
[16:59] <Lunar_Lander> it's just sitting there
[17:00] <Upu> something not right then :)
[17:00] <Upu> double check your circuit :)
[17:00] <Lunar_Lander> yea
[17:00] <Lunar_Lander> how is it supposed to sound?
[17:00] <Lunar_Lander> like a high-low tone?
[17:00] <Upu> yeah give me 2 mins I'll wire it back up
[17:00] <Lunar_Lander> thanks

[17:27] <Lunar_Lander> that is funny
[17:27] <Lunar_Lander> I asked him for 22k
[17:27] <Dan-K2VOL> Kevin you can also just check with an ohm meter if it's out of circuit

[17:40] <Lunar_Lander> ok I need 2 22k ones
[17:41] <Lunar_Lander> one 27k ones
[17:41] <Upu> what have you got ?
[17:41] <Lunar_Lander> seems like I have to visit him tomorrow again
[17:41] <Lunar_Lander> I have 2 4.7k
[17:41] <Lunar_Lander> 10k, those 2 12k
[17:41] <Upu> how many ?
[17:41] <Lunar_Lander> 2 times 100 and 2times 180
[17:41] <Lunar_Lander> one 10k, two 12k
[17:41] <Upu> oh
[17:41] <Upu> yeah you need to visit again :)
[17:41] <Lunar_Lander> yeah
[17:42] <Upu> you could run 2 10ks in parallel to get 5k
[17:42] <Lunar_Lander> yeah true
[17:42] <Upu> 10+12k in series gives the 22k
[17:42] <Lunar_Lander> yeah
[17:42] <Lunar_Lander> fortunately those cost only 20 eurocents
[17:42] <Lunar_Lander> so that is not the worls
[17:42] <cuddykid> built my balloon filler :) the 40mm pipes from wickes work a treat

[18:03] <Upu> or whatever its called

[18:03] <Upu> prime meridian
[18:04] <cuddykid> will be about 70 miles or so to west
[18:04] <cuddykid> fsphil, yeah! haha
[18:04] <cuddykid> unless it goes horrendously wrong
[18:04] <Upu> assume it will go wrong
[18:04] <fsphil> always prepare
[18:04] <Upu> make sure your code can handle it
[18:04] <fsphil> I'm -6 degrees and i still tested it
[18:04] <cuddykid> how would I test it?
[18:05] <fsphil> I had my PC send gps data
[18:05] <fsphil> from another flight
[18:05] <fsphil> or you could load the program with some gps strings, feed them manually
[18:05] <fsphil> are you using tinygps?
[18:06] <cuddykid> yeah
[18:06] <fsphil> you could feed that fake gps data
[18:07] <cuddykid> I'll have a go :) thanks
[18:07] <fsphil> I plan to cross the meridian at some point :)

[18:09] <Lunar_Lander> yeah
[18:09] <Lunar_Lander> fsphil btw
[18:09] <Lunar_Lander> Upu and I found out that I have got wrong resistors
[18:09] <Lunar_Lander> 12k instead of 22k
[18:09] <fsphil> d'oh!
[18:09] <Lunar_Lander> yeah
[18:09] <Lunar_Lander> so I have to go to the shop again tomorrow
[18:10] <Upu> buy a few
[18:10] <Lunar_Lander> yeah
[18:10] <Lunar_Lander> like 5?
[18:10] <fsphil> maplin have a box of about 20 different kinds
[18:10] <Upu> you'll always use them when you make tutorials for UKHAS :)
[18:10] <Upu> I just bought strips of 10
[18:10] <fsphil> see if they have a kit
[18:10] <cuddykid> maplin have loads for fairly cheap
[18:10] <fsphil> it's really handy having lots of values when I was trying to get the shift right
[18:11] <Upu> I got most of mine from Maplins
[18:11] <Upu> they do some kits too
[18:11] <cuddykid> yeah, mine didn't come out brilliant - a 800mhz shift is not ideal but will do!
[18:11] <Upu> its hard to calculate it
[18:11] <Lunar_Lander> yea
[18:11] <cuddykid> but apparently shift narrows in flight (due to temp) so should be ok
[18:11] <Upu> I should find a decent circuit sim and test it
[18:11] <Upu> not by that much
[18:12] <fsphil> cuddykid, 800mhz? :)
[18:12] <Upu> that would be an issue :)
[18:12] <cuddykid> ooooops lol

[19:20] <fsphil> I miss having a car
[19:20] <fsphil> and I've only been driving a few months :)
[19:21] <fsphil> I have to leave back the helium cylinder, but it's 20 miles away and when I arrange a left they always change their minds at the last minute
[19:21] <fsphil> the poor woman must hate me now :)
[19:22] <fsphil> (the woman I got the helium from)
[19:22] <Upu> that car was good fro HAB as it was an Avant and had somewhere to put an antenna on :)
[19:23] <fsphil> I used a little mag mount, goes anywhere
[19:23] <Lunar_Lander> yeah
[19:23] <Upu> I have a mag mount now
[19:23] <fsphil> though I'm always afraid of scratching something
[19:24] <Upu> they do scratch
[19:25] <fsphil> this one hasn't so far, but could just be luck
[19:30] <fsphil> a little rubber pad would be good, but then there'd be no grounding
[19:34] <Dan-K2VOL> yeah the Digi m10 dev kit magmount scratched a large paintless square into my car roof when other people slid it around while I wasn't there :-(
[19:35] <fsphil> eek
[19:35] <Dan-K2VOL> fsphil I think you'll be ok with a thin rubber pad I think there's no actual electrical contact needed for mag-mounts to the plane - or you'd have to remove paint :-)
[19:35] <fsphil> fair point
[19:35] <fsphil> isn't the paint conductive?
[19:36] <Dan-K2VOL> I don't think so, I can check, but paint isn't typically
[19:36] <Dan-K2VOL> I'll go out to the car tonight with a meter :-P
[19:38] <fsphil> I've got an old phone cover made from thin rubber, would do the job perfectly
[19:38] <Dan-K2VOL> nice
[19:38] <fsphil> I'd be afraid of it falling off when the car picks up speed
[19:38] <Dan-K2VOL> that's a possibility

[21:48] <jcoxon> cool
[21:48] <Lunar_Lander> thanks
[21:49] <Lunar_Lander> but the wrong resistors obviously
[21:50] <Lunar_Lander> even with the program for "M6UPU TEST" it writes nonsense
[21:50] <fsphil> try tuning around a bit -- they rarely fall on 434.075 exactly
[21:50] <Lunar_Lander> so another visit to the shop tomorrow
[21:50] <Lunar_Lander> yeah
[21:50] <Lunar_Lander> when I tune up, the pitch of the tone gets highe
[21:50] <Lunar_Lander> +r
[21:50] <Lunar_Lander> and tune down, lower
[21:50] <fsphil> that's right
[21:51] <Lunar_Lander> it doesn't warble like in upu's video
[21:51] <Lunar_Lander> it only does that one dit-dit-dit
[21:51] <fsphil> yea that doesn't sound righ
[21:51] <fsphil> right
[21:51] <fsphil> even one rtty tone will sound different
[21:51] <Lunar_Lander> yeah
[21:51] <fsphil> it sounds like it's in a reset loop
[21:51] <Lunar_Lander> so I'll see what happens tomorrow
[21:51] <Lunar_Lander> yeah
[21:52] <Lunar_Lander> and then I'll try mattltm's way of wiring it
[21:52] <Lunar_Lander> btw I decided to buy a full lot of 4 22k resistors
[21:52] <Lunar_Lander> because I was told resistors are important :)
[21:53] <fsphil> resistors in general are important - though no particular value
[21:53] <fsphil> best to have a mix of them
[21:55] <Lunar_Lander> yeah
[21:58] <jcoxon> haha i think that the balloon will fly directly over wb8elk's farm
[21:59] <Lunar_Lander> PWM is pulse width modulation, right?
[21:59] <fsphil> indeed
[21:59] <Lunar_Lander> thanks
[22:00] <fsphil> it could be slow PWM you're hearing
[22:00] <fsphil> though the program would have had to enable it
[22:00] <Lunar_Lander> yeah
[22:01] <Lunar_Lander> I am just explaining the pinout of the Uno to a friend
[22:01] <Lunar_Lander> the PWM plays no role in the circuit?
[22:01] <fsphil> none, all the timing is done in software

[22:56] <Lunar_Lander> what is the approx range of the NTX2 when in a balloon
[22:56] <Lunar_Lander> 50 km, 100 km?
[22:56] <fsphil> seems like that in a lot of the states
[22:56] <fsphil> depends on the altitude Lunar_Lander
[22:57] <Lunar_Lander> yes
[22:57] <Lunar_Lander> like at 20000 m
[22:57] <RocketBoy> fsphil: yeah - I got some good results with stuff we did way back
[22:57] <RocketBoy> probably ok for flights in the UK
[22:58] <fsphil> Lunar_Lander, 500km maybe - I've received telemetry from cambridge launches when they are about 18km up
[22:58] <RocketBoy> must be down then - thats the altitude there abouts
[22:59] <fsphil> In a tree
[22:59] <fsphil> but not the forest
[22:59] <RocketBoy> we wre using one today over about 250Km methnks
[22:59] <Lunar_Lander> ah
[22:59] <Lunar_Lander> thanks
[22:59] <fsphil> ooh and a nice swimming pool
[23:00] <fsphil> the maximum is about 560km but that depends on a nice flat horizon at the receiving site
[23:00] <Lunar_Lander> yeah
[23:00] <fsphil> could probably receive further than that but the receiver would need some altitude himself
[23:00] <fsphil> like a mountain
[23:01] <fsphil> I was hoping to listen in RocketBoy but we lost our office net connection just after you launched
