[02:12] <Darkside> erek: go look at tracker.sondehub.org :-)
[02:12] <Darkside> lots of balloons on htere
[02:12] <erek> :)
[02:14] <erek> Darkside, ever heard of anyone using a Automated Parafoil to guide the Balloon back to the launch point as closely as possible?
[02:14] <erek> or some other system
[02:14] <Darkside> daveake has been doing something like that
[02:15] <erek> Hmm
[02:16] <erek> Darkside, https://pdfs.semanticscholar.org/37cd/733b8cdcf2d8b059b75cb7dc6906360bfc93.pdf
[02:16] <erek> Darkside, https://ntrs.nasa.gov/archive/nasa/casi.ntrs.nasa.gov/20160004964.pdf
[02:16] <Darkside> yes im very sure its a thing
[02:17] <erek> https://hackaday.com/2012/10/02/weather-balloon-payload-that-almost-guides-itself-back-to-you/
[02:17] <erek> i was working on something myself
[02:17] <Darkside> personally i enjoy the chase, so i'm not so concerned about something flying back
[02:18] <Darkside> and depending on wind conditions, it might not always be possible anyway
[02:18] <erek> heh
[02:18] <erek> Darkside, have you chased many?
[02:18] <Darkside> soemthing around 55 launches so far
[02:18] <Darkside> along with many many radiosonde chases
[02:18] <erek> i don't even have my Ham Radio license :(
[02:19] <Darkside> where are you located?
[02:19] <erek> could you go to prison for launching APRS systems without a valid Ham Radio license?
[02:19] <erek> Darkside, USA, PA
[02:19] <Darkside> get an amateur radio license
[02:19] <Darkside> you only need a technician license to be able to use APRS in the US
[02:19] <erek> how illegal is it without one?
[02:19] <Darkside> uh
[02:19] <Darkside> dont do it
[02:20] <Darkside> you're using a network of receivers that are run and monitored by the amateur radio community
[02:20] <Darkside> someone will notice
[02:20] <erek> they'll report it?
[02:20] <Darkside> sure
[02:20] <erek> :(
[02:20] <Darkside> just get your license
[02:21] <Darkside> no-one in here will ever recommend that you break the law to perform a flight, be it in aviation regulations or radio spectrum usage regulations
[02:21] <Darkside> do it properly
[02:25] <daveake> +1
[02:26] <daveake> The basic technician license is very easy
[02:26] <daveake> And you'll learn a bit about radio
[02:27] <Darkside> learning a bit about radio is pretty damn important to doing a balloon flight properly
[02:27] <Darkside> since if you get the radio bits wrong, you wont be recovering your payloads
[02:27] <erek> daveake, you've messed about with automatic return payloads?
[02:28] <erek> Darkside, it'd be interesting to somehow extend beyond just the basic camera payload, but to a full blown astrophotography payload
[02:29] <daveake> In theory. Not entirely sure about its legality here (or rather, hire the CAA might interpret the regulations)
[02:29] <erek> like telescopic, and also polar alignment at altitude
[02:29] <daveake> That's a lot of work
[02:31] <erek> imagine the advantages, no clouds to deal with, a lot better optics to the objects
[02:31] <Darkside> its not something you want to be doing with your first flight
[02:31] <erek> :(
[02:31] <Darkside> first flight is working out how to launch, track and recover
[02:31] <Darkside> well, probably first few flights is that
[02:31] <Darkside> then once you have all that right, then you go and put the expensive stuff on
[02:32] <erek> Darkside, what kind of payloads would you start with?
[02:32] <Darkside> just basic tracking, and maybe a camera if you want
[02:32] <Darkside> so if you lose it, its not a large financial loss
[02:32] <Darkside> becuase if you dont get the tracking right, you *will* lose your payload
[02:32] <erek> ever lost a payload yet?
[02:33] <Darkside> twice, neither had anything important onboard
[02:33] <Darkside> should note - thats lost payloads that i had originally intended to recover
[02:33] <Darkside> have done a few flights where there was no intent on recovering
[02:36] <erek> hmm
[02:37] <erek> they've thought of everything haven't they!
[02:37] <erek> https://en.wikipedia.org/wiki/Balloon-borne_telescope
[02:37] <Darkside> you'll note those are usually on very large zero-pressure balloons, due to the weight of the payloads
[02:38] <erek> i wonder if any zeppelin could ever achieve near-space altitudes
[02:39] <erek> carrying a really big compressed reflector telescope and camera
