[17:31] same as before but transparent, I used to strip Ali off [17:32] at least now don't have to do that [17:34] used to strip Ali, like use multiple cutup clear Aliexpress balloons? [17:34] where did you get the film you use now? [17:36] I had a roll of 90cm wide aluminised film so had to strip Al layer with NaOH [17:37] I bought same film but without the Al layer from some random balloon making company on alibaba [17:37] I wish there was a reliable and assured quality stuff around [17:37] aha, now I get it :) [17:37] rr on that [17:39] yeah, from my tests with film its clear it needs to be transparent, any colour of the film will make it heatup and burst within a day or of flight [17:40] sure, that was totally counter-intuitive [17:40] I flew first clear balloon to see how much worse it was vs aluminised. So it was a controlled failure experiment. [17:41] Instead it had almost no solar gain [17:44] snaked (~snaked@user/snaked) left irc: Ping timeout: 245 seconds [17:51] :) thats the best ones!

[17:59] it's just APRS data sent over a LoRa link anyway [18:00] yeah, most of the modules use the sx1278 or 1276 [18:01] so with that, LoRa APRS uses arbitrary frequency like 433775000 [18:01] but the LP filters in the modules will kill the signal so you have [18:01] its pure lora on aprs.fi webpage [18:01] so with a 868 board, I'd just set the frequency to something 868775000 [18:01] and with same frequency on the iGate, it should work [18:02] I guess, what are you going to use it for+ [18:02] ? [18:02] I started to use this on 433: https://github.com/lora-aprs/LoRa_APRS_iGate [18:02] and it seems to work just fine [18:02] yes, I have tested it [18:03] small comunety in Swe using it, maby 12-15 stations up [18:03] but it supports only 433 so why not switch to 868 where less noise, smaller antennas and more available channels [18:03] and shorter range :) [18:03] well yes, just that a bunch of spare 868 modules would be put to work [18:04] and also in the USA, not sure why there is no lora on 433 [18:04] so anyway they could put the 868's to some good use [18:04] China does it on 434 [18:04] indeed! [18:04] china is know to do a lot of things including crazy [18:04] :) [18:05] yes but the do use the Metric in aviation where all other use feet, I dont know what to think , lol [18:05] so if USA could put it to use on the 902-920 (i guess this is the right range for US) [18:05] 915 920, dont know [18:06] kristianpaul (~paul@user/kristianpaul) joined #highaltitude. [18:06] so I will test if that at all works on 900 on some arbitrary frequency [18:06] my own lora aprs is qrv as LY2EN-5 and the igate is LY2EN-4 [18:07] likley, I tested the sx1278 all the way up to 920 , worked fine even though the datasheet says max 520 [18:07] the 1276 is 1100Mhz something iirc [18:07] kristianpaul (~paul@user/kristianpaul) left irc: Excess Flood [18:08] any other flights planed for the fall? or are you waiting for the spring? [18:09] no I'm just so lazy [18:09] spent half of the summer to deliver the APRS digipeater on the GSM tower [18:09] now I can't solder the solar panels 0.5V each so just thinking to put up a 4.75V one for launch because the voltage drops naturally anyway [18:10] secret of soldering solar cells is low temp 320° [18:10] also tried to play with LDO but on existing pcb's it just adds extra wires on the top, so need to redesign the pcb for the ldo [18:10] 4.75V? thinfilm solar? [18:10] yeah [18:11] the gps in action is quite a good voltage regulator :) [18:11] they are VERY low curent, nothing like the polycristaline cells [18:11] really needs a SC to work [18:11] yep so it is almost never 4.75V [18:12] except without load [18:12] but hey I don't mind a supercap [18:12] cant drive anything usefull with the test cells I bought [18:12] :) [18:12] or two in series as the dont like over voltage [18:13] there was anew SC out, have not folloed closely but it could take iver 3V ?

[18:35] tried made-in-china.com and it was even worse [18:35] I sourced some film but it was EXPENSIVE! [18:35] all the people who advertise that they make "balloon film" said they don't make balloon film [18:36] http://www.ddpackaging.com/ thos does [18:37] but lets see, reading back the mails... [18:38] 200m minimum order at 14$ m2 [18:38] I also bought a roll of BOPET film and it was a totally useless [18:38] no sealing pe layer?
