[07:49] <solitude> anyone ever flew a hab and recorded it in night time?
[07:52] <gonzo__> you mean a video after dusk?
[07:52] <solitude> yeah
[07:54] <solitude> looks cool from space, not sure how it looks from near space https://www.youtube.com/watch?v=ev9oPUNaqXE
[07:55] <gonzo__> a few have sone still pics, and got some nice sun set images. But doubt you would get anything at all after full sunset
[07:55] <solitude> you mean just black sky and dark earth? thats what I thought too
[07:55] <gonzo__> and recovering a balloon after dark is going to be fir more difficult
[07:55] <gonzo__> far
[07:57] <gonzo__> a couple opf us went off to recover someone else's balloon that landed near. It was in an open unplanted field, with the silver foil balloons still attached and floating at eye height. We almost stepped on it before we actually found it.
[08:01] WillDWork (c2498339@gateway/web/freenode/ip.194.73.131.57) joined #highaltitude.
[08:03] <WillDWork> Upu - I see you've got some of those LoRa modules in - is there a cheap P&P option?
[08:03] <fsphil> I got some fuzzy pics after sunset on my last flight. you could make out towns and cities from the light polution
[08:04] <fsphil> didn't recover that one, so I guess it doesn't count :)
[08:04] <gonzo__> was it yours with the nice sunset pics phil?
[08:04] <fsphil> yea
[08:04] <solitude> fsphil: that sounds cool. Do you have those photos?
[08:05] <fsphil> solitude: https://www.flickr.com/photos/fsphil/sets/72157643394259575/
[08:05] <fsphil> most of the night time shots are totally black :)
[08:05] <fsphil> but a few came out with some ground detail
[08:06] <gonzo__> if you did a night flight that you wanted to recover, you would be best to put a tracking tx that will last till morning and go and recover in the first light
[08:06] <solitude> ok
[08:07] <fsphil> with a larger lens it should be possible to do better night time pictures
[08:07] <solitude> Images are a bit low res. But overall seems pretty dark, and no clouds?
[08:07] <solitude> what fov was that, fsphil?
[08:07] <fsphil> yea the ground was covered in patchy cloud, why I think most of the images are totally black
[08:08] <fsphil> good question
[08:08] <fsphil> it was the raspberry pi camera
[08:08] <amell> fsphil: this is ssdv?
[08:08] <fsphil> which google tells me is 40 degrees vertical fov
[08:08] <fsphil> amell: yea
[08:09] <gonzo__> and trensmitting the images to ground, so you have to keep the res quite low
[08:09] <solitude> not much compared to GoPro
[08:09] <gonzo__> snap
[08:09] <amell> fsphil: thats a lot of money to drop in the sea. presumably that was the plan? :)
[08:09] <fsphil> amell: lol, yea
[08:09] <fsphil> it wasn't that expensive
[08:09] <fsphil> just a pi, camera, batteries and ntx2
[08:09] <gonzo__> still cheaper than even a suecond hand gopro
[08:09] <solitude> yeah
[08:09] <fsphil> and gps
[08:10] <amell> Oh i see you didnt pay for it. thats ok then :)
[08:10] <gonzo__> if you do it right, the gas and balloon arte the most expensive part
[08:10] <fsphil> and yes I didn't pay for this one :)
[08:10] <gonzo__> gettin g some one else to fund your hobby, nice
[08:10] <gonzo__> (or these days we call it kickstart!)
[08:10] <fsphil> https://www.flickr.com/photos/fsphil/13621479353/in/set-72157643394259575 -- clearest night shot I got that time, Dublin
[08:10] <solitude> why is the sky so bright in tis pic? https://www.flickr.com/photos/fsphil/13621454763/in/set-72157643394259575
[08:11] <solitude> arent they in order?
[08:11] <amell> sunrise?
[08:11] <fsphil> they're backwards
[08:11] <fsphil> flickr oddity
[08:12] <fsphil> solitude: the sun was still below the horizon, the camera took a longer exposure
[08:12] <fsphil> the sky is still blue at 30km
[08:12] <fsphil> just not much
[08:12] <fsphil> compared to the bright ground during the day time
[08:13] <fsphil> for normal daytime exposures it's basically black
[08:13] <solitude> so the sun location can have such dramatic effect on sky color, huh?
[08:14] <fsphil> yea. well in that shot the sun is already shining on the bit of atmosphere above the paylod
[08:14] <fsphil> but not the ground
[08:15] <fsphil> there is a better example of that somewhere
[08:15] <fsphil> https://www.flickr.com/photos/fsphil/13621436625/in/set-72157643394259575
[08:15] <solitude> https://www.flickr.com/photos/fsphil/13621469713/in/set-72157643394259575 and https://www.flickr.com/photos/fsphil/13621454185/in/set-72157643394259575
[08:15] <solitude> clearly clouds are lower, but sky is brighter
[08:15] <fsphil> you can see the shadow of the earth in that. I love it
[08:16] <fsphil> just different exposure times solitude
[08:16] <fsphil> and different angles of the sun
[08:17] <solitude> yeah
[08:18] <solitude> thanks for the info

[09:10] <cipher_> will a "propane regulator" like this work for helium and hydrogen? https://translate.google.com/translate?hl=en&sl=ru&tl=en&u=http%3A%2F%2Fwww.list.am%2Fitem%2F3142843
[09:13] <daveake> no and no
[09:15] <fsphil> a hydrogen regulator isn't called that for no reason :)
[09:16] <cipher_> Oh, I thought yesterday you guys said its universal.
[09:16] <daveake> No we didn't
[09:17] <daveake> The thread is different between flammable gasses (e.g. h2, propane) and others (e.g. helium)
[09:17] <daveake> So that blows your idea out of the water right there

[09:18] <daveake> Finally, don't take advice on what to use from anyone other than a gas manufacturer
[09:18] <daveake> gas/regulator
[09:18] <daveake> Finally finally, just go with helium as this is all going to go wrong

[09:24] <amell> that page looks fine to me.
[09:24] <craag_philcrump> If you don't want to take the correct precautions when using hydrogen please at least stick with helium, and even then please do things properly. For your own sake.
[09:24] <Geoff-G8DHE_> he's gone again
[09:24] <amell> probably extinguished by a hydrogen explosion...
[09:25] <amell> He needs to use helium!
[09:26] <amell> btw, this page says hydrogen flames are difficult to see. I dont agree, they are pink.
[09:26] <craag_philcrump> very transparent though
[09:27] <craag_philcrump> compared to a tv/film (carbon) flame for example
[09:27] <amell> maybe we should do a new video. https://www.youtube.com/watch?v=cQvpK9cl0No

[09:32] <amell> i dont seem to be able to edit this wiki
[09:32] <fsphil> filled with just hydrogen, it probably wouldn't be all that dramatic
[09:33] <fsphil> latex is the dangerous bit
[09:34] <craag_philcrump> failure of an incorrect regulator would be a lot more dramatic
[09:34] <fsphil> oh yes
[09:37] <SpeedEvil> Regulators are quite reliable
[09:38] <daveake> My concern is that he doesn't seem to understand what he's been told, so the chances of it going right are low.
[09:39] <SpeedEvil> Definitely film it. he could be the next Colin Furze

[11:24] <murb> urg vat, always changing the rules :(
[11:24] <pd3t> i do not pay tax then
[11:25] <murb> you're now supposed to charge the receipents countries rate of vat, except when you're not.
[11:25] <pd3t> when i pay they have to make the product more valuable
[11:25] <murb> and the exceptions keep changing, or they're unsure of them.

[11:26] <nats`> it depends if the gov of origin country has some clearance rules with the destination
[11:26] <fsphil> I've always paid the VAT rate of the country I'm buying from in the EU
[11:26] <nats`> fsphil as an individual or a company ?
[11:26] <pd3t> put the bill on the name of a canadian company and set the shipping address to europe
[11:26] <fsphil> individual
[11:26] <nats`> it's normal so
[11:26] <murb> nats`: i'm both ;-)
[11:26] <fsphil> pd3t: heh, I've seen people do this :)
[11:27] <nats`> it's a simplification considering that the exchange volume is fair in EU
[11:27] <murb> i trade in souls apparently!
[11:27] <daveake> Yes, if you're vat-registered then you should be able to pay ex-vat
[11:27] <nats`> as a company you have a number
[11:27] <murb> nats`: nothing to do with being a company or not.
[11:27] <nats`> you give this one to the seller and it allows to exchange VAT directly at gov level
[11:27] <murb> tis to do with being registered for vat or not.
[11:27] <pd3t> indeed i have
[11:27] <daveake> murb is correct

[11:27] <nats`> it's pretty rare no ?
[11:28] <pd3t> indeed but the company is buying it and not me
[11:29] <murb> nats`: quite common if you're self employed.
[11:29] <murb> as turn over limit before you have to register is something like 17k¬
[11:29] <murb> (this is a country specific thing.)
[11:30] <murb> then if you trade toomuch with other eu countries you may have to have seperate registrations as well :(
[11:31] <nats`> oky murb I didn't know that I need to check in france because I always do without
[11:32] <nats`> murb in France it's not possible unless you do those micro company with simplified status
[11:32] <nats`> as an individual without company status you can't be VAT registered
[11:32] <murb> nats`: so you can't be self employed?
[11:32] <nats`> you can be "auto entrepreneur"
[11:33] <nats`> it's a specific status with simplified system to be like a society
[11:33] <murb> what if you cut down trees and sell the wood?
[11:33] <nats`> limited to some k¬ by year
[11:33] <nats`> uhhmmmm good question

[15:00] <fsphil> the blitzortung gps is quite insensitive

[15:11] <fsphil> they takes forever to lock
[15:11] <craag_philcrump> patch+ublox was much better than the helical for me
[15:11] <fsphil> and are quite good at losing it

[15:59] <mattbrejza> the dongles are 3.2MSPS (max)
[15:59] <Flerb> I was just thinking couldn't a hab record a portion of a shortwave band
[15:59] <Flerb> Or any band actually
[16:00] <mfa298> sample rate will be linked to the frequency range you want to cover. Audio tends to be 44KHz as the human ear can hear up to 20KHz (although that get's worse with age)
[16:02] <Flerb> mfa298: say for 250 kHz would it just be 250 samples per second?

[16:05] <mfa298> Flerb: sorry that should have been 44ksps (1000 samples per second) - you may want to look up aliasing (I think that's the right term)
[16:05] <SpeedEvil> (when it leaves the coverage of this radio in ~300km time)
[16:05] <SpeedEvil> 11m/s, so 40km/h, so ~8h in coverageish

[16:19] <fsphil> for me, just to see what it can hear
[16:19] <fsphil> it would be interesting to try it when another flight was in the air
[16:20] <SpeedEvil> you can do fun stuff basically acting like a radio telescope for transmitters - locating them precisely
[16:20] <fsphil> inject the gps pps signal into it somehow
[16:20] <fsphil> someone here did something similar iirc
[16:21] <SpeedEvil> That would of course be nice - but isn't really required if you can hear a sync signal from al the things at once

[21:04] <kf7fer> since I'm posting about their flight... on their last flight they had a problem where the GPS failed to report a postion during descent. It does appear the payload descended spinning and fairly fast.
[21:05] <kf7fer> could that have caused the gps not to get a lock?
[21:05] <kf7fer> the tracker was updating voltage and temperature but had a fixed position

[21:05] <kf7fer> last report was something like 54k feet (to use an outdated measurement)
[21:06] <kf7fer> then 8 transmissions... 60s apart.. with the same GPS coordinates
[21:06] <Upu> I was being sarcastic
[21:07] <craag_philcrump> That can very easily cause issues with the gps if the gps antenna isn't omnidirectional
[21:07] <kf7fer> Sorry. Then again I never did get Benny Hill (though I loved the girls)
[21:08] <craag_philcrump> Helical antenna would be best for coping with that. Chip antenna seems to cope. Patch antennas will likely have problems.
[21:09] <kf7fer> craag_philcrump: ok thanks. I'm pretty sure the tracker would have used either a chip or helical

[22:04] <amell> daveake: re rf98w module, how did you connect the SMA plug to the module? its rather small.
[22:04] <daveake> solder
[22:04] <amell> solder what? just normal wire?
[22:04] <daveake> just solder
[22:05] <daveake> to the pin
[22:05] <daveake> and wire to the leg
[22:05] <fsphil> I ended up using wire for both. cheated
[22:05] <daveake> Obviously this is not robust, so the socket also got soldered down to the board that the rfm was on
[22:05] <amell> would it matter if i soldered two wires, im just not sure if it has to be shielded i.e. one inside the other
[22:05] <daveake> nah
[22:05] <amell> ok. just keep it short i guess.
[22:06] <fsphil> worked in my case
[22:06] <daveake> short as you can
[22:06] <fsphil> about 5mm each
[22:06] <amell> so the module basically needs to be right next to the sma socket.
[22:06] <kf7fer> aadamson: I shouldn't admit this, but at one time James told me that I was responsible for 25% of the PCB orders for the then-named Dorkbot PCB service. The box of shame is high and deep as a result.
[22:07] <kf7fer> being local to the service didn't hurt :-)
[22:07] <daveake> In this one I cheated by removing the audio socket from a pi, and putting the SMA in its place. I cut the pin short and soldered some thin coax to it https://twitter.com/daveake/status/509725097721339904/photo/1
[22:07] <daveake> amell no you can use coax
[22:08] <amell> hmm, needs a steady hand.
[22:08] <daveake> check
[22:08] <daveake> check for shorts after
[22:09] <amell> wondered about connecting a rf98w AND a rfm69 to the same arduino&

[22:55] <Bob_Saget> does anyone know what material B-64's envelope is?
[22:55] <aadamson> Nice LeoBodnar, I hadn't look at them in a while... last time I did 100mm x 100mm boards in 10qty was 200eu, for 30 10cm x 10cm was $97us, and the stencil required you to order 10 board from pcb-pool
[22:55] <aadamson> ^ 30 boards from hackvana that is
[22:56] <DL7AD> aadamson: is there a price list from hackvana?
[22:56] <aadamson> yeah
[22:56] <aadamson> http://tinyurl.com/hvpcbfaq
[22:57] <aadamson> he offers some package price deals and in my case fit my panels to that size
[22:58] <craag_philcrump> has anyone tried ragworm for one-offs?
[22:59] <DL7AD> aadamson: and what prepeg material are they using?
[22:59] <craag_philcrump> I noticed them advertising at EMF
[22:59] <aadamson> DL7AD, jump over to #hackvana and ask, I don't know
[22:59] <DL7AD> okay thx
