[12:31] I posted a question to the mail group, but it usually takes some time to show up. So let me ask it here too... [12:32] I plan to launch small payload. piZero+piCamera. How can I stabilise it from spinning ? [12:32] wind vane type arrangement seems to work ok [12:32] but will add weight [12:32] that helps it face into the wind [12:32] a kind of vertical wing ? [12:33] can do it in a few ways, but sure [12:33] think weather-vane [12:33] ok. one idea ! [12:33] thats the way we've done it in the past, it works ok [12:34] but regardless if you are capturing pictures then you should be implementing the poor-mans sharpness filter [12:35] I was thinking of making a suspension of 3 parallel lines, separated from each other like 10cm ... could make payload align to balloon, and balloon doesn't spin that much I suppose ? [12:35] the balloon might spin [12:35] who knows... [12:35] ive found that if you do the sharpness filter trick, even if the payload is spinning a bit you still get good photos [12:37] if you're using daveake's code i think you get that already [12:37] I'll also record video, so this won't work [12:38] no, it wont [12:38] good luck then [12:38] Not tried it, but you can get the picam to emit stills whilst it's recording video [12:38] Laurenceb (~laurence@223.141.208.46.dyn.plus.net) joined #highaltitude. [12:38] wind vane probably best approach [12:38] Pretty sure there's something in the Python lib for that [12:38] but if its an ultralight payload im not sure how well it will work [12:39] usually need a bit of weight in the centre for it to be reliable [12:40] daveake: flown one of the new cameras yet? [12:40] lol lockdown [12:40] i need to find better glass for mine [12:40] Wish I could have flown my test one before this started [12:40] but damn is it heavy [12:40] My list f flights-to-do is growing somewhat [12:41] yeah same [12:41] i really want to get thie DVB-S payload up [12:41] and then david rowe and I have some modem test flights to do [12:41] cool [12:41] we want to try a flight with the payload transmitting at -20 dBm for shiggles [12:42] the modem should handle it [12:42] daveake, taking stills while recording video works very good. I used it, with python camera module. [12:42] New position from 03KB6CAG-12 after 0313 hours silence - 12https://tracker.habhub.org/#!qm=All&q=KB6CAG-12 [12:43] Thanks michal_f ... I remember looking at it, not quite sure if I tested it all on the desk but certainly not in a flight yet [12:44] tested in flight here. [12:44] i wonder if i could make the DVB-S palyload capture still and downlink wenet at the same time... [12:44] ok I was thinking this; https://paste.pics/5e5c5dc22e63ea4c3a7804d34120f9b8 [12:44] if upper triangle was firmly attached to neck, this could possibly reduce spinning [12:45] assuming the balloon doesnt spin [12:45] and you still need your parachute to go somewhere [12:46] parachute at the neck maybe ? [12:46] dunno [12:46] i still think stick out the back is probably your best option [12:46] make the paylaod point into the direction of travel [12:46] https://www.youtube.com/watch?v=YGxc_tdGBgI this is short vid from last flight. This spin was partly due to cord not unrolling fully when releasing [12:47] I've found something that is ideal in lockdown .... coding an ADS-B parser :) [12:48] Normally there'd be too much data coming in :) [12:48] daveake: going to fly an rtlsdr on a flight? [12:48] yup [12:48] record some data for later, if you don't make it before things go back to normal :) [12:48] heh [12:48] See what range ADS-B gets [12:49] hopefully you dont get *Too* many packets at once [12:49] So far I've got the rx side all done, with a list of flights with current positions etc [12:49] Now need to think of a download packet format and method of cyclind ghrough the more imopirtant flights [12:49] ADS-B reception has been done from space before... but i suspect some fancy algorithm were involved to deal with transmit collisions [12:50] daveake: just send the one thats furthest away [12:50] There are satellites in the ADS-B network now [12:50] Yeah basically that [12:50] But it'd be nice to have a dashboard showing all the flights [12:50] heh [12:50] that'll be fun to downlink [12:51] I'm calculating the distance and remembering the furthest currently and so far [12:51] yeah [12:51] daveake: are you using dump1090 to capture the data, or..? [12:51] i guess you dont need to seend much info. callsign, lat, lon, alt. [12:51] Yes dump1090 [12:51] It emits packets on port 30003 [12:51] Callsign is a slight pain as only one of the messages includes it [12:52] Mostly aircraft Tx position (every 0.5s) with an ID, but the ID-->Callsign bit is every 5 secs [12:52] At least, that's what's coming out of dump1090 [12:53] I read it uses an offline lookup table so I don';t think the aircraft is sending the callsign [12:53] there's another standard too isn't there, as well as ads-b? [12:53] There's a USA one on a lower freq,, if thast's what you mean [12:54] And there's a separate system that the glider pilots set up [12:54] i think it was acars? [12:54] "The protocol was designed by ARINC and deployed in 1978, using the Telex format." heh :) [12:54] hehe [12:55] Anyway this thing is for ADS-B only [12:55] the glider pilot one is FLARM, which is a closed proctol with a monopoly equipment provider [12:55] ah that's it [12:55] but it has been reverse engineered and theres the open glider network that can decode it [12:55] i think there was someone using ads-b on a satelite right? [12:55] Right, I made a receiver but not used it [12:55] theres a few now [12:55] a few ADS-B sat receivers i mean [12:56] neat [12:56] ADS-B is collected by sats now and relayed down to the ground over a separate link [12:56] that would be helpful for finding planes that crash i imagine? [12:56] So flights across oceans now get tracked all the way [12:56] Yep [12:57] It's pissed off the flat-earthers who liked that fact that long flights in the southern hemisphere seemed to disappear for much of the flight :) [12:57] haha [14:00] OLHZN (~Tory@cpe-66-66-13-40.rochester.res.rr.com) joined #highaltitude.
