[06:14] <Upu_M0UPU> yeah its TXing fine
[06:14] <Upu_M0UPU> warming up in the sun
[06:14] <Upu_M0UPU> slowly
[06:14] <Upu_M0UPU> TCXO is drifting back up
[06:15] <Martin_G4FUI> Seems to be a TUXO at the moment ...
[06:15] <Upu_M0UPU> well C = consistent :)
[06:16] <Upu_M0UPU> consistantly changes with temp :)

[06:17] <Martin_G4FUI> With large rates of change of solar energy it must be a tough ask right now!
[06:18] <Martin_G4FUI> Thankfully Domino seems to be very tolerant of frequency drift
[06:19] <Upu_M0UPU> yeah but sadly dl-fldigi has no auto tuning
[06:19] <Upu_M0UPU> settling down anyway
[06:20] <Martin_G4FUI> I'm trying to resist the urge to tweak the receiver settings to keep it centered as it's interesting seeing how it drifts
[06:22] <Upu_M0UPU> Had to retune it was out of the3000hz for me
[06:26] <Upu_M0UPU> it needs to warm up
[06:27] <Upu_M0UPU> I'm not entirely sure that temp sensor is reading correctly
[06:27] <Mik_WD8MNV> the txco is part of the transmitter module?
[06:27] <Upu_M0UPU> yes
[06:28] <Upu_M0UPU> possibly fault
[06:28] <Upu_M0UPU> faulty
[06:28] <Mik_WD8MNV> k
[06:28] <Upu_M0UPU> as they haven't drifted on previous flights
[06:29] <Martin_G4FUI> It might have a linearity problem of some sort, the resolution seems to be very coarse below -20 deg or so
[06:30] <Mik_WD8MNV> ans SEBA5 is out of range of everything? or you think it's down?
[06:30] beingaware (~aware@pi.icanhaz.org) joined #highaltitude.
[06:31] <Upu_M0UPU> not sure the GPS stopped owrking on it
[06:31] <Upu_M0UPU> it could still be up
[06:31] <Upu_M0UPU> it was floating at 40km
[06:31] <Upu_M0UPU> so it could be anywhere

[06:31] <Mik_WD8MNV> pretty high to be floating isn't it? how long can it do that?
[06:32] <Upu_M0UPU> good altitude to float
[06:32] <Upu_M0UPU> temps are ok and winds are quick
[06:32] <Upu_M0UPU> I floated one around that over night but it rose and burst in the morning
[06:32] <Upu_M0UPU> K6RPT floated one a little lower which made it across the atlantic in 3 days
[06:38] <Martin_G4FUI> It may just be coincidence, but I had a data glitch from B-14 which occurred exactly at the same time as a meteor ping on my GRAVES receiver ...

[06:46] <heathkid> okay... it's morning
[06:46] <Upu_M0UPU> B-14 warming up nicely
[06:46] <jcoxon> time to start recruiting some of northern listeners
[06:47] <Upu_M0UPU> well if it follows current path and speed we are for at least a day

[06:53] <jcoxon> that said at 105km/h ground speed it would be a long way away now
[06:54] <Upu_M0UPU> yeah that could be anywhere by now
[06:54] <Upu_M0UPU> 40km float is amazing
[06:55] <daveake> same as pie5 then :p

[07:48] <malgar> Do you report in your NOTAM the extimated landing area? Here in Italy we need to write the NOTAM 45 days before launch so is quite difficult
[07:49] <LeoBodnar> morning Upu_M0UPU
[07:49] <Upu_M0UPU> is it feasible the temp sensor is out ? The battery shouldn't be recharging below zero but it is

[07:49] <LeoBodnar> I have just recharged LiPo at -20C overnight Upu_M0UPU
[07:49] <Upu_M0UPU> they aren't suppose to recharge at that temp

[09:41] <G0TDJ_Steve> LeoBodnar: Quick question. On B14's telemetry, you have Solar Panel: 0.66 Is that volts?
[09:41] <LeoBodnar> Yes Steve, it's only a single cell solar panel so voltage is low
[09:42] <LeoBodnar> I think it maxes out at 0.7v open circuit voltage
[09:42] <G0TDJ_Steve> Interesting. I salvaged a few small glass panels from those cheap garden lights from Maplin. They give 5v off load
[09:42] <LeoBodnar> There must be a few of them in series
[09:43] <LeoBodnar> solar panel is nothing more than a big photodiod
[09:43] <LeoBodnar> *diode
[09:43] <G0TDJ_Steve> Possibly. They're about 30mm square
[09:43] <LeoBodnar> So 0.7v is magic number
[09:43] <LeoBodnar> It is also temperature dependent, solar panels love cold temperatures
[09:43] <G0TDJ_Steve> Glad to know that
[09:46] <enkidu> solars at low temperatures are less vulnerable to self drain, are they?

[09:46] <LeoBodnar> voltage is higher, drain is lower, it's overall better
[09:47] <enkidu> amorphous silicon with coating? argh
[09:47] <G0TDJ_Steve> I may have mis-remembered, maybe I had a couple in parallel
[09:47] <LeoBodnar> it says open circuit voltage 2.2v and you can see 3 cells
[09:47] <G0TDJ_Steve> enkidu: What's up with that?
[09:47] <LeoBodnar> so 0.7 x 3 ~ 2.1
[09:48] <G0TDJ_Steve> Yep Leo
[09:48] <enkidu> glass coating is just unneeded mass plus it reflects some light
[09:48] <LeoBodnar> surely ok for a garden light :)
[09:48] <G0TDJ_Steve> Ah, yes. I just whipped them off cheap garden lights to play with. Before I was interested in HAB :-)
[09:49] <DL1SGP> heh
[09:49] <G0TDJ_Steve> They now sell them in my local 'Pound Shop' all shapes and sizes, all with the same solar cell
[09:49] <enkidu> Ive used structures from old power diodes as they were very small
[09:51] <enkidu> it gave me a little power, but enough for simple AM radio
[09:51] <G0TDJ_Steve> Neat :-)
[09:51] <G0TDJ_Steve> Did you hear about these guys at Washington University who use ambient RF to power devices?
[09:51] <enkidu> I heard of them

[09:53] <enkidu> G0TDJ_Steve: have you ever heard "singing" AM mast?
[09:53] <G0TDJ_Steve> No?
[09:53] <LeoBodnar> diode contact in dissimilar metals?
[09:54] <enkidu> not only, but mainly.
[09:54] <G0TDJ_Steve> Is that similar to the people who received radio broadcasts in their head because of metal in their fillings?
[09:54] <enkidu> Imagine open circuit mast operating in thunderstorm
[09:55] <G0TDJ_Steve> Go on
[09:55] <enkidu> broadcast power was enough to make mast and clouds act as giant megaphone
[09:55] <G0TDJ_Steve> Blimey....
[09:55] <LeoBodnar> haha
[09:55] <bbjunkie> lol
[09:56] <G0TDJ_Steve> Must have been very strange

[10:11] <enkidu> if it become 40km alt floater... it would be easy to find if only had solars

[10:12] <LeoBodnar> Tom used solar before I think so maybe he can combine the tech

[11:25] <GMT> seems odd that the predictor for B-14 wants to send it northwest all the time, but B-14 has other ideas
[11:25] <enkidu> can we have meteo radar/clouds overlay on tracker?
[11:25] <craag> GMT: The predictor assumes it's ascending.
[11:26] <la3eq> looks as B-14 is comming my way? have no heard it yet.
[11:26] <craag> la3eq: The blue circle is the estimate on range. You're still outside it.
[11:26] <GMT> la3eq: you're the only one up in that part of the world, so if it does go your way then we are relying on you
[11:26] <la3eq> yep...B-14 has his own minde setup about where tpo go ;)
[11:27] <fsphil> It's not B-having

[11:57] <SpeedEvil> If you're searching for 1960s stamps - you have to now do stamps (1960,1961,...) - this obviously has real issues for when you're searching for random 1-wire parts, and want to find ds18*

[13:26] <Upu_M0UPU> and the NTX2's drift
[13:26] <Upu_M0UPU> also it needs very precise frequency steps
[13:26] <GMT> so what is B-14 using for TX?

[13:28] <Upu_M0UPU> well if you can solder the components a number of people have done it
[13:28] <Upu_M0UPU> or just use the new NTX2B when it comes out
[13:28] <Upu_M0UPU> should be soon

[14:18] <jiffe99> I've got a question for you guys, how are you tracking balloons once they get close to the ground? Our last launch we had both an APRS transmitter and a SPOT satellite transmitter and the last APRS position we picked up was way off from the location the SPOT was giving us

[14:20] <number10_M0MDB> most people rely on getting a position in the air between 200-500m and you should know roughly where it is to receive from the ground when you are within 1km
[14:22] G0TDJ_Steve (d49f4aee@gateway/web/freenode/ip.212.159.74.238) joined #highaltitude.
[14:23] <GMT> jiffe99: which was the correct position, the one from the APRS or the SPOT?
[14:23] <jiffe99> GMT: the spot was correct because it was giving us positions as we were catching up to it, the last aprs position was way up in the air
[14:24] <Willdude123> Tremendous fun finding LF/MF commercial radio stations on websdr
[14:24] <GMT> jiffe99: the APRS position is only based upon the last position sent into the APRS system
[14:25] <Upu_M0UPU> jiffe99 if you get with 500 meters of it the radio transmission can usually be picked up
[14:25] <Upu_M0UPU> and it tells you exactly where it is
[14:25] <PB0NER> websdr is cool.. and it might anable trackers to track their baloons even when direct rx is impossible...
[14:25] <Upu_M0UPU> tracking network is so good in the UK its rare not to have it below 1km
[14:26] <Upu_M0UPU> and with the prediction you can guess sort of where it is
[14:27] <db_g6gzh> Upu_M0UPU: the amp is cool but the regulator is hot (7V external feed)
[14:27] <Upu_M0UPU> hmm
[14:27] <Upu_M0UPU> you can check that giving out the correct (5V) voltage
[14:28] <jiffe99> Upu_M0UPU: gotcha, guess I could write something up to take its last position, trajectory and ground altitude to figure it out too assuming it doesn't shift
[14:28] <Upu_M0UPU> we can import APRS into Spacenear.us as well
[14:28] <Upu_M0UPU> so you can get the benefit of the live predictor

[16:19] <Laurenceb__> yes
[16:19] <SpeedEvil> LeoBodnar: balls-out IC engines are quite good
[16:19] <G0TDJ_Steve> So Habitat would have to recognise the '++' as duplicates.
[16:19] <Laurenceb__> most new large lorries are ~40%
[16:19] <db_g6gzh> They might not be duplicates in nobody decoded the original
[16:19] <LeoBodnar> I think database backend has to filter out the duplicates and that's it
[16:19] <Laurenceb__> if they rev at ~70% output power
[16:20] <G0TDJ_Steve> Sounds like a plan
[16:20] <db_g6gzh> The sequence number should be sufficient
[16:20] <jcoxon> its unfortunately more complicated
[16:20] <DL1SGP> sorry gentlelids what is the freq for ToGo1 :) ?
[16:20] <jcoxon> so sequence isn't used due to flight computer resets

[16:37] <Upu_M0UPU> amazing what a 9km high antenna can do :)
[16:37] <Upu_M0UPU> I know
[16:37] <Upu_M0UPU> you have to be the unluckiest person with weather
[16:38] <Upu_M0UPU> your predicted landing is north of Bury St Edmunds
[16:38] <Ugi_> sadly, so with everything, but we got there in the end
[16:38] <Ugi_> now we have to try & find it!
[16:38] <gm4jtj_> front end here is a nokia dolphin tetra rx board
[16:38] <Upu_M0UPU> well go park up near the predicted landing
[16:39] <Upu_M0UPU> your decent rate is low

[16:39] <Upu_M0UPU> which is a good thing :)
[16:39] <DL1SGP> less impact crater :)
[16:39] <Upu_M0UPU> still receiving gm4jtj_ ?
[16:39] <Upu_M0UPU> thats way out of radio horizon nice one :)
[16:40] <Wouter-[pa3weg]> I will give B-14 a try later
[16:40] <Upu_M0UPU> mind you if you have any altitude at all there is only sea between you and the payload
[16:41] <Upu_M0UPU> yeah its drifting back down Wouter-[pa3weg]
[16:41] <gm4jtj_> yes still getting green decodes
[16:41] <Upu_M0UPU> Excellent
[16:41] <Upu_M0UPU> I don't think this one is going to be short of coverage

[16:42] <G0TDJ_Steve> Hi Ned
[16:42] <Upu_M0UPU> and by us I mean B-14
[16:42] <PB0NER> Togo seems to behave as predicted
[16:42] <gm4jtj_> that was 432.8km and +11dB above noise floor
[16:42] <Upu_M0UPU> Yagi gm4jtj_ ?

[16:43] <PB0NER> I did 536km with a 910 and no preamp on a diomond x5000
[16:43] <Upu_M0UPU> not even polarised the right way :)
[16:43] <ned98> Me and my friends are planning to build a space balloon, but our biggest problem is it's tracking... What's the best way to do it?
[16:43] <Upu_M0UPU> but that should do it :)
[16:43] <G0TDJ_Steve> Space Balloon?
[16:43] <Upu_M0UPU> well ned98 firstly its not space but lets get that small detail out of the way
[16:44] <Upu_M0UPU> before people jump down your throat :)
[16:44] <Upu_M0UPU> which country are you in
[16:44] <ned98> sorry :)
[16:44] <Upu_M0UPU> its about 1/3rd of the way to space
[16:44] <Upu_M0UPU> lets call it near space
[16:44] <ned98> I'm in Italy, central zone
[16:44] <Upu_M0UPU> ok
[16:44] <PB0NER> space officially starts @100km as far as I remember (you can be called astronaut if you pass 100km)
[16:44] <Upu_M0UPU> we have someone else from Italy doing one at the moment
[16:45] <Upu_M0UPU> however
[16:45] <Upu_M0UPU> 1/ Come hang about on IRC - you've done this one already
[16:45] <Upu_M0UPU> 2/ http://ukhas.org.uk/general:beginners_guide_to_high_altitude_ballooning
[16:45] <DL1SGP> italy is scary, plenty of water around!
[16:45] <Upu_M0UPU> a radio tracker is the best bet and they aren't too hard to make
[16:45] <Upu_M0UPU> http://ukhas.org.uk/guides:linkingarduinotontx2
[16:45] <Upu_M0UPU> there that should do for the moment :)

[16:49] <Upu_M0UPU> no dumb bigs
[16:49] <Upu_M0UPU> bugs
[16:49] <PB0NER> hmm what is happening on b14... not sending anything but the beeps for 3mins
[16:49] <PB0NER> oh got packets again
[16:49] <Upu_M0UPU> PB0NER if solar drops below a certain level it only TX's every 5 mins
[16:50] <PB0NER> oh ok, cool feature
[16:50] <gm4jtj_> this was a system on 432.8 used by eddie stobart among others. The amps are available on ebay and can be modded for 300watt amateur use. see g4fev website for details of my conversion.
[16:50] <PB0NER> ground track will be messed up in <15 mins....
[16:50] <gm4jtj_> sorry 428MHz

[16:51] <x-f> PB0NER, in 75 minutes :)
[16:51] <Upu_M0UPU> just a TX amplifier though ?
[16:51] <Mik_WD8MNV> my wifi dongly quit last night... anyone have a favorite they really like?
[16:52] <gm4jtj_> there is a rx box with it that splits the input and f
[16:52] <Upu_M0UPU> Cat5 cable Mik_WD8MNV :)
[16:52] <LeoBodnar> excellent, saved for reading
[16:52] <Upu_M0UPU> ok
[16:52] <Upu_M0UPU> did you get yourself a callsign yet Leo ?
[16:52] <LeoBodnar> gm4jtj_: you are currently horizontal polarised ?
[16:52] <Mik_WD8MNV> i don't have access to the router... need a radio
[16:53] <gm4jtj_> ..has the tx filter as well as a simple BFG541 preamp...nothing special .
[16:53] <Upu_M0UPU> gm4jtj_ https://dl.dropboxusercontent.com/u/63720513/Images/HAM/Rotator/IMG_0796.JPG
[16:53] <gm4jtj_> yes horizontal but its getting weaker with me now
[16:54] <Upu_M0UPU> but impressed even horizontally polarized its making no real difference
[16:54] <LeoBodnar> Got bored looking for 3 letter combinations Upu_M0UPU lol
[16:54] <Upu_M0UPU> haha
[16:54] <LeoBodnar> any good suggestions?
[16:54] <LeoBodnar> Advanced exam is in two weeks
[16:54] <Upu_M0UPU> yeah get full and then use M0BOD
[16:54] <Upu_M0UPU> M0LEO is taken
[16:55] <LeoBodnar> ok :D
[16:55] <db_g6gzh> Upu_M0UPU: I always think that counterweight is a shame when there could be another antenna 8-)
[16:55] <Upu_M0UPU> yeah I know db_g6gzh :)
[16:55] <Upu_M0UPU> when I can afford it
[16:55] <GMT> how do you check which c/s are taken, which are free?
[16:55] <db_g6gzh> fair enough 8-)
[16:56] <chrisstubbs> Is it worth doing the advanced? I have my M6 and hardly use it to talk to anyone, so the increased power dosent bother me
[16:56] <Upu_M0UPU> well I use qrz.com but yes in fairness it only works if someone has registered themselves

[16:56] <G0TDJ_Steve> chrisstubbs: Access all areas....
[16:56] <craag> chrisstubbs: Operating abroad is the big plus.
[16:56] <Upu_M0UPU> well chrisstubbs lets you use recipricol license i.e using ARPS in the air aboard
[16:56] <LeoBodnar> I want to try APRS abroad chrisstubbs
[16:56] <craag> and /mm
[16:57] <Upu_M0UPU> and yes
[16:57] <SpeedEvil> I have doubt's a 2mw generator is $5000
[16:57] <Upu_M0UPU> amusingly we could have used that on the original LOHAN recovery
[16:57] <Upu_M0UPU> though "boat" was pushing it
[16:58] <chrisstubbs> Can you do marine VHF?
[16:58] <craag> hehe
[16:58] <craag> no
[16:58] <craag> Marine is different, need seperate licenses.
[16:58] <Upu_M0UPU> no you can use your ham license on a boat in coastal waters ?
[16:58] <LeoBodnar> If you are swimming in the open sea is it /MM or /M?
[16:58] <Upu_M0UPU> or is it non coastal waters ?
[16:58] <Laurenceb__> SpeedEvil: yeah
[16:58] <Laurenceb__> http://www.alibaba.com/product-gs/533008375/supply_Jichai_2000kw_generator_2mw_diesel.html?s=p
[16:58] <Upu_M0UPU> just /M
[16:59] <Upu_M0UPU> you need to be on a boat to use /MM

[16:59] <craag> below the high-tide line is /mm
[16:59] <Upu_M0UPU> also chrisstubbs once you have full license you can apply for NOV's to your license
[16:59] <Upu_M0UPU> you can ask for cool things for experimental purposes
[16:59] <LeoBodnar> sure /MM is on ham bands,marine licence on marine bands on the boat
[16:59] <Upu_M0UPU> they will of course completely ignore your requests
[17:00] <chrisstubbs> Ah okay cool :) Do you learn much RF/electronics stuff?

[17:00] <Upu_M0UPU> with the permission of the captain
[17:00] <Upu_M0UPU> in the same way /M means you're not operating from your registered address
[17:00] <Upu_M0UPU> I'd go park on Barton Hill Ugi
[17:01] <Ugi_> heading that way Upu_M0UPU
[17:01] <chrisstubbs> fingers crossed for not lainding in the sewage works
[17:02] <Upu_M0UPU> they normally fall short of the predicted landing
[17:02] <Upu_M0UPU> normally
[17:02] <Upu_M0UPU> wonder if its bringing the balloon back with it
[17:02] <GMT> Ugi - take A14 to BSE, exit 43, head NE on A143, we will keep you updated
[17:04] <Ugi_> Fab - will do. Thanks GMT

[17:17] <G0TDJ_Steve> Hopefully cleared the trees....
[17:17] <chrisstubbs> bad launch is possible, seems unlikley to be a bad balloon if its from the same batch as your good one
[17:17] <chrisstubbs> anyway time for dinner, if there are any more details you would like to know RocketBoy let me know. thanks again for letting us try it out!
[17:18] <Willdude123> I made the board for 6Q, should I go with 7C or 7Q?

[17:18] <RocketBoy> it came out of the same box as the one I used

[18:05] <Bo_DK> hihihih
[18:06] <fsphil> hello
[18:06] <DL1SGP> hi again fsphil
[18:06] <Bo_DK> the goal from start have been a very compact unit that on its own can track a baloon
[18:06] <Bo_DK> and decode
[18:06] <Bo_DK> ie it can talk to server
[18:06] <fsphil> LeoBodnar: the date field has helped a lot :)
[18:06] <Bo_DK> get list of active flights
[18:06] <Bo_DK> user picks with lcd and buttons
[18:06] <Bo_DK> press go
[18:06] <Bo_DK> and it takes care of rest
[18:07] <LeoBodnar> It's not a little project Bo_DK it's quite a challenging one!
[18:07] <LeoBodnar> So don't feel depressed
[18:07] <DL1SGP> you mean "takes care of the rest" as in "tunes the rig, adjusts rotors, does decodes of the signal" ?
[18:07] <Bo_DK> I'm
[18:07] <DL1SGP> that sounds like a cool project!
[18:07] <Bo_DK> yep
[18:07] <Bo_DK> thats the plan
[18:08] <Bo_DK> first goal is to just talk to server and tell servos where to aim
[18:08] <Bo_DK> habrotate by craag can do most of it

[18:08] <Bo_DK> i just cant do the servo part
[18:08] <DL1SGP> basically if there is an active flight the user chooses to listen to there should be data on the habitat, you can poll the CSV or whatever format you want to extract the position
[18:08] <DL1SGP> then give the unit an GPS receiver to know its own position
[18:09] <DL1SGP> do math to get azimuth and elevation bearing
[18:09] <Bo_DK> excatly
[18:09] <Bo_DK> habrotate can do that
[18:09] <DL1SGP> yea
[18:09] <mikestir> Bo_DK: if you're still having trouble getting the BBB to drive the servos you could always offload that to an arduino or something
[18:09] <mikestir> then just communicate between the arduino and BBB serially or whatever
[18:10] <Bo_DK> hehe

[18:22] <fsphil> I got a beagle bone. silly thing has a microhdmi port
[18:22] <Bo_DK> hehe
[18:23] <Bo_DK> i'm running headless
[18:23] <SpeedEvil> The PRUs are damn near made for running servos
[18:23] <Bo_DK> end "product" will not have a screen
[18:23] <Bo_DK> PRU's?
[18:23] <SpeedEvil> PRUs are 2 embedded 32 bit 200(?)MHz embedded controllers on-die on the BBB SoC
[18:24] <Bo_DK> funny thing is that ADAfruit have made a library.... program examples.... etc etc
[18:24] <Bo_DK> even how to wire a servo to BBB
[18:24] <SpeedEvil> They have their own little bit of RAM and can - with the right setup - use GPIO
[18:24] <Bo_DK> it just dont work like they show it
[18:24] <SpeedEvil> This means that you have a really fast high end microcontroller to do all the PWM stuff - assuming you've run out of - or the PWM units are not capable of it
[18:25] <SpeedEvil> What issues are you having.

[18:27] <Bo_DK> or in fact all the programming
[18:27] <Bo_DK> hardware i can do

[18:27] <Bo_DK> nice thing about a box is that you can take it down from shelf

[19:19] <kpiman> Yes Upu_M0UPU, caught b-14 on launch and tracking went well left overnight, will be out of range soon though.
[19:19] <Upu_M0UPU> yeah its going soon
[19:19] <Upu_M0UPU> you've been very well placed
[19:19] <Wouter-[pa3weg]> as soon as you have the tracking number he will ship new units out I think
[19:19] <Geoff-G8DHE-M> Beside the map to the right location and heights of points, you can click and enter your own height rather than ground level
[19:20] <Upu_M0UPU> it has this constant very high pitched clicking in the back ground
[19:20] <Geoff-G8DHE-M> See here for B-14 for me at present, changed the scale to see local hills Capture3 in a moment

[19:45] <Upu_M0UPU> craag's software interfaces with that
[19:45] <Upu_M0UPU> would probably work

[19:52] <Bo_DK> hmm...
[19:52] <Bo_DK> i get that

[20:40] <Upu_M0UPU> it can do
[20:40] <Bo_DK> ok

[20:40] <Bo_DK> just thinking new approach to automatic decode
[20:40] <Bo_DK> to aim an arduino and servos....
[20:41] <Bo_DK> just wonder if PSTRotate can send where to aim over serial?
[20:41] <Bo_DK> and have arduino use that
[20:41] <Upu_M0UPU> PSTRotate just controls the rotator
[20:41] <Upu_M0UPU> you would tell it where to aim
[20:41] <Bo_DK> yes... but do PSTRotate send serial data?
[20:42] <LeoBodnar> Bo_DK: is it possible for you to start from setting up a remote receiver on websdr or globaltuners ?

[20:45] <Upu_M0UPU> Bo_DK ignore PSTRotate
[20:45] <Bo_DK> why?

[20:45] <Upu_M0UPU> read current position etc
[20:45] <LeoBodnar> -39C ouch
[20:45] <Upu_M0UPU> all PSTRotate does is issue these commands

[20:47] <Bo_DK> my approach to the aiming part...
[20:47] <Upu_M0UPU> the arduino in this case is receiving the serial commands and controlling the motors
[20:47] <Bo_DK> an arduino that listens for serial commands
[20:47] <Bo_DK> excatly
[20:47] <Upu_M0UPU> you don't need PST rotate
[20:47] <Bo_DK> oh
[20:47] <Upu_M0UPU> you can just issue say M180
[20:47] Helios_STOLEN (~HeliosFA@requiem.soton.gia-lan.co.uk) left irc: Ping timeout: 264 seconds
[20:47] <Upu_M0UPU> and it will rotate to 180' azimuth
[20:47] <Upu_M0UPU> press C
[20:47] <Upu_M0UPU> and it returns the current location
[20:48] <Bo_DK> yes..... but i want it to be kind of automatic
[20:48] <Bo_DK> habrotate the first link
[20:48] <Upu_M0UPU> well thats what your software does
[20:48] <Upu_M0UPU> gets location of balloon
[20:48] <Upu_M0UPU> works out where to point the antenna
[20:48] <Upu_M0UPU> issues the command via serial
[20:48] <Bo_DK> heehe.....
[20:48] <Bo_DK> i dont have software yet
[20:48] <Bo_DK> only habrotate

[20:49] <Bo_DK> and reason i picked PSTRotate is that it can read habrotate directly
[20:49] Helios_STOLEN (~HeliosFA@requiem.soton.gia-lan.co.uk) joined #highaltitude.
[20:49] <Bo_DK> and send out serial
[20:50] <Bo_DK> without me have to code pc software

[20:50] <Bo_DK> i would as habrotate gets its pos from a file

[20:51] <Willdude123> Bo_DK, language.
[20:51] <craag> I thought you'd put gpsd into habrotate?

[20:51] <Bo_DK> craag: no no..... the beagle bone route is on the shelf
[20:51] <craag> And tbh if you're interfacing with one specific rotator, skipping pstrotator will save a lot of pain.

[20:52] <craag> erm you're still going to need the gpsd bit....
[20:52] <Bo_DK> craag: not on linux platform
[20:52] <craag> well then look at my mobile-aprs scripts, one of which is a python nmea parser
[20:53] <Bo_DK> craag: problem is that i dont have the skills to get servos to work on BBB
[20:53] <Bo_DK> Raspberry pi is out due to lack of cpu power to decode

[20:53] <Upu_M0UPU> decode what ?
[20:54] <Bo_DK> Data from usb dongle
[20:54] <craag> you're still aiming at the whole decoder.... ok.... not sure that's a good idea at this point.
[20:54] <Bo_DK> ie radio
[20:54] <Upu_M0UPU> just get it from the database
[20:54] <craag> ^^
[20:54] <Upu_M0UPU> like habrotate
[20:54] <mfa298> Bo_DK: it sounds like you need to go back to what I started doing with you a couple of weeks ago. Work out exactly what it is you're trying to put together in detail. Then you can work out from there if existing software fits in to what you're doing.
[20:54] <craag> ^^^^
[20:54] <daveake> An Arduino could do this let alone a Pi
[20:54] <craag> mm
[20:54] <Bo_DK> what about decode what comes from USB dongle?
[20:54] <craag> the whole internet bit gets a bit complex on an arduino
[20:55] <Upu_M0UPU> question have you tried manually tracking a flight yet ?
[20:55] <craag> Bo_DK: Forget that for now
[20:55] <Upu_M0UPU> do you have a rotator ?
[20:55] <daveake> Well you can get a shield with IP stack
[20:55] <daveake> So possibly not that tricky
[20:55] <daveake> That said I'd use a Pi
[20:55] <craag> daveake: Yeah but they're twice the price of a Pi, and not as easy to use.
[20:55] <daveake> Oh I know :-)
[20:55] <daveake> Not suggesting an Arduino as a good solution
[20:56] <daveake> Just making the point that CPU power shouldn't be an issue here

[20:56] <craag> mm agreed

[20:58] <daveake> +1
[20:58] <mfa298> +lots
[20:58] <Bo_DK> that is what i TRY
[20:58] <Bo_DK> doing it on a beagle bone was over my head
[20:58] <craag> So stop talking about decoding

[20:59] <Bo_DK> ok... lets say i pick rapberry pi and get it working....
[20:59] <Bo_DK> hmm
[20:59] <Bo_DK> then i want to decode also
[20:59] <craag> no
[20:59] <Bo_DK> shit to little cpu power
[21:00] <LeoBodnar> Remote rotator + websdr. Bingo!
[21:00] <Bo_DK> then the choice of platform at start would be wrong
[21:00] <Bo_DK> raspberry pi is to weak for webadr
[21:00] <Bo_DK> i have been told that before i even started out first try
[21:01] <Bo_DK> i was told to pick BBB as that had enough cpu power to do webadr
[21:01] <mfa298> Bo_DK: they are both linux systems with gpio pins, It should be possible to develop a lot of the tracking code on any system like that
[21:01] <Bo_DK> which i would end up doing at some point anyway
[21:02] <Bo_DK> mfa298: well.. my "only" problem was controlling a damm servo on the BBB
[21:02] <Bo_DK> habrotate was working

[21:06] <Bo_DK> for decode fldigi
[21:06] <mfa298> Bo_DK: (not wanting to be rude) having read some of the #beagle logs I think the the first problem you have is you need to listen to the advice you are given and research the answers you are given. They gave exactly the same answers I would have for your questions.

[21:59] <Laurenceb__> LeoBodnar: I thought of a nutty idea - use the butane to lower the float altitude at night
[21:59] <LeoBodnar> Good point! pushing -40C now
[22:00] <LeoBodnar> what level ?
[22:00] <Laurenceb__> i dont know
[22:00] <LeoBodnar> what was the liquid streaming on today's launch pad?
[22:00] <Laurenceb__> if you had a black bag
[22:00] <Laurenceb__> i dont know - proton?
[22:01] Helios_STOLEN (~HeliosFA@requiem.soton.gia-lan.co.uk) left irc: Ping timeout: 245 seconds
[22:01] <LeoBodnar> proton liquid?!
[22:01] <Laurenceb__> odd
[22:01] <Laurenceb__> its room temperature liquid powered
[22:02] <Laurenceb__> so anyway - black bag so the butane is always gas during day
[22:02] <Laurenceb__> at night it has to descend to evaporate.. maybe
[22:02] <Laurenceb__> do you still have that graph of butane altitude ?
[22:02] <LeoBodnar> Did I have one? lol
[22:03] <LeoBodnar> Let me talk to myself!
[22:03] <Laurenceb__> on your site - you did a graph of butane and iso-butane condensation altitude
[22:04] <LeoBodnar> found something http://leobodnar.com/balloons/files/butane2.png

[22:05] <LeoBodnar> Interesting how B-14 almost does not drop for night float - only 300m altitude difference
[22:05] <Laurenceb__> yeah
[22:05] <LeoBodnar> I guess it has been stretched so much so there is almost no elasticity left
[22:05] <Laurenceb__> hmm so you might be able to make it descend to ~4km at night
[22:06] <Laurenceb__> of course there is then risk of rain
[22:06] <Laurenceb__> but the butane gives quite a lot of extra bouyancy
[22:06] <Laurenceb__> might make an interesting idea
[22:06] <LeoBodnar> THis is probably quintessential floater holy grail but I'd prefer lower flight level for the night
[22:07] <LeoBodnar> It's a pity we only have 20-30 grams of payload/ballast to play with

[22:34] <Geoff-G8DHE> LeoBodnar, Is it that it shows up at night more as the voltage drops, looking during the charging period they seem to be there as well ?
[22:35] <Geoff-G8DHE> but to a lesser degree of volts drop

[22:35] <LeoBodnar> When the charging is on during the day it will pick up and respond to any extra power demands from GPS. During the night the battery is the only source and very fragile at that.
[22:36] <LeoBodnar> So abundance of power during the day and lack of it during the night...
[22:36] <Geoff-G8DHE> Yes what I mean is its doing it EVERY 2 hours day or night, justthat it shows more when on the battery alone.

[22:40] <LeoBodnar> Yes, exactly that. I'd prefer having degraded navigation accuracy during the night than fresh satellite data downloads

[22:42] <Geoff-G8DHE> Isn't the ephemeris downloaded every 2 hours?
[22:43] <Laurenceb__> yes
[22:43] <LeoBodnar> Maybe. Are the essential or can be postponed?
[22:43] <Geoff-G8DHE> and valid for 4 hours
[22:43] <Laurenceb__> i doubt you could set this on ublox
[22:44] <Laurenceb__> i did meet the guy who does the upload once
[22:44] <Laurenceb__> could pay him a big bribe

[22:44] <Geoff-G8DHE> Think there going to be sent whatver you do, all you could do is switch off, but then it will load at switch on ...
[22:44] <Laurenceb__> theres a control room in Cheyenne mountain
[22:45] <Geoff-G8DHE> are no switch off at that point and then you would have to wait for a further 2 hours to be sent again, so switch off every two hours at night in sync.... :-(
[22:46] <Laurenceb__> its quite simple
[22:46] <Laurenceb__> http://en.wikipedia.org/wiki/Cheyenne_Mountain_nuclear_bunker
[22:46] <Laurenceb__> break in and beat up the operator
[22:46] <Geoff-G8DHE> Not sure about an 8-10g payload doing much damage!

[22:47] <LeoBodnar> At any hot start it consumes so much current that a few of them will kill the battery - as B-13 has successfully proven
[22:48] <Geoff-G8DHE> Do you know what the current drawn is, and for how long ?
[22:48] <LeoBodnar> Haha I have been doing radio monitoring shifts in a similar one
[22:51] <mfa298> Is there a guy in the Cheyenne mountain control room who says "Chevron one encoded" ?
[22:51] <SpeedEvil> Laurenceb: I do wonder how long GPS would work for if the ground side went silent

[22:52] <LeoBodnar> But can the client be stopped from getting the updates?
[22:52] <LeoBodnar> Are they essential?
[22:53] <Geoff-G8DHE> They tell you exactly where the orbit is for the satellites, so it would take longer to work out without it, as it must do at start up hence the longer cold start times.

[22:55] <Geoff-G8DHE> Does it not say in the UBLOX spec what the cold and warm start times are ?

[22:57] <Geoff-G8DHE> LEA-6A/ LEA-6R
[22:57] <Geoff-G8DHE> Cold Start (without aiding) 26 s 27 s

[22:57] <Geoff-G8DHE> Hot Start (without aiding) 1 s 1 s

[22:57] <Geoff-G8DHE> AQrgh
[22:58] <Geoff-G8DHE> sry looks like 25+ seconds from cold as opposed to 1 sec from hot
[22:58] <LeoBodnar> can you save them and upload every two hours via aided asist?
[22:59] <Geoff-G8DHE> how would you upload them ? They are produced on the fly every 2 hours not something that can be pre-loaded
[23:00] <Geoff-G8DHE> I think its the Almanc data that can be up to a week in advance
[23:00] <Laurenceb__> battery seems to be holding up as well as yesterday
[23:01] <Geoff-G8DHE> Right beddy byes for me! CUL

[23:11] <SpeedEvil> Geoff-G8DHE: you could in principle produce assist data that would likely to be good enough for degraded position
[23:13] <LeoBodnar> and stop the updates download from sats
[23:13] <LeoBodnar> ?
[23:18] seventeen (021bf710@gateway/web/freenode/ip.2.27.247.16) left irc: Quit: Page closed
[23:21] <SpeedEvil> maybe
[23:22] <SpeedEvil> just fake the assist data
[23:31] <Laurenceb__> isnt there a command to load assist data?
[23:31] <Laurenceb__> it might help i guess
[23:32] <SpeedEvil> you may need to forward predict the assist data for the flight
[23:32] <SpeedEvil> I don't know how much the assist data is documented
