I dont think it has updated in the last day, and predictions are being run against the model 2021072806 dataset. [08:52] Yeah looks like it's not updated since then ... my hourly has the same model [08:52] The admin guys are in #habhub you can join there and mention it or I'll do that [08:53] vincentsan (~vincentsa@212-198-230-5.rev.numericable.fr) joined #highaltitude. [08:54] PE2BZ, SA6BSS-Mike1, final design sent to the fab: http://www.up-in-the-air.com.s3-website-eu-west-1.amazonaws.com/designs/Up4r3.pdf [08:55] I will now work on a revision with a step-up so it can work with just 2 solar cells in series. Do you have any reference in mind? [08:59] XC9141/2 seems promising (only 2 caps and 1 2.2¼H inductance for the D version) but there are a lot of different flavors A, B, C, D, E types that I don't really understand... [09:05] New position from 03KD2FOU-11 after 0312 hours silence - 12https://tracker.habhub.org/#!qm=All&q=KD2FOU-11 [09:07] vincentsan, last time I tried 2 cells to 3v3 stepup it required an inductor for 150 mA current and the models I could find where as heavy as 4 solar cells. [09:10] daveake, alistair , I am on the habhub channel, Mark finds out there is some overload protection active for to much requests on that noaa server. [09:11] daveake Thanks. How frustrating.

[09:22] PE2BZ, the recommended inductance for XC9141/2 are 5x5mm or 4x4mm and weight ~0.2g. It is still much better than 1.6g for 4 solar cells, no?

[09:43] well, as you said earlier, I don't think I need more than 14 dBm for a HAB. Lora-E5 will draw 26mA for 14 dBm and GPS about the same but they won't work at the same time. So I think if I can get around 30mA at 3V, I will be fine with this set up. [09:45] reg710 gives 30mA and I found reg711 that gives 50mA but they still require 4 cells. I think I could go down to only 2 in this revision if I find the good IC. [10:37] yes, dont bother with 2 cells [10:38] its will just be as heavy as 4/6 cells with the needed supercap [10:38] and you are back to the 1040 [10:38] if you going with 2 cells setup [10:39] any inductor based boost ic like mcp1640 will peek at 200-300mA before it start conducting [10:44] ok so you are saying inductor based boost ic will not work? [10:44] with very large cells and high solar [10:44] angle [10:45] so best simplicety just 4 of teh smallest cells 39x19 and a reg710 or hx4002 you will get a good compromise imho that is :) [10:45] ok, that makes sense. thank you! [10:46] would reg711 give a little more juice just in case? [10:46] cant say [10:47] looks like the reg710 but with 50mA instead of 30mA: https://www.ti.com/lit/ds/symlink/reg711-25.pdf?ts=1627490534044&ref_url=https%253A%252F%252Fwww.google.com%252F [10:48] really cant say [10:48] ok, i'll stick with what has been tested then ;-) [10:49] for example YO3ict used the reg710 with a ubblox max 8 , he got at best 12-13 solara startup angle [10:50] sounds good to me! [10:50] I never tried the max8 but with L70m39 I get about the same nr, but with a atgm336 I get ca 19L [10:50] ° [10:51] I slowly increase tx power [10:51] in first 10 min I let it tx with 4mW then I increase the power one step every 10 min [10:51] :+1 [10:52] so I have max power 13mW after 30 [10:52] min [10:52] so, mainly its the gps that determines the startup, not the tx [10:53] ok, I don't even think I need 14dBm at the end. I've read a few posts about Lora attached to balloons and it seems well received by (too) many gateways [10:53] so that could improve with the 711 but only one way to know... :)( [10:53] :) [10:54] using lora or are you doing aprs with it? [10:54] lora [10:54] ok [10:54] not sure aprs is supported by LORA-E5 but maybe [10:54] PE2BZ will experiment with that I think [10:54] what is the main ic? [10:54] sx1278? [10:55] Yes and yes [10:55] then it does , the 95/96 modules I dont know [10:55] STM32WLE5J8 [10:55] Mentioned SX127X in the specs [10:55] slow vnc... [10:56] But if the board arrives I first have to get a clue about the difference between STM and 328p programming ;-) [10:56] Me too [10:56] I have ordered a ST-LINK v3 as well to experiment [10:57] ,any of the stm ics you can connect a usb directly to , no need for serial converter or isp programming [10:57] BTW, do you have a good PCB fab to recommend in Europe? I have ordered from OSHpark but I am afraid it will cost a lot more now with custom + new VAT since 1st of July... [10:57] the rs41 is stm [10:57] using jlcpsc in china [10:58] do you have to pay custom + VAT? [10:59] not to this day [10:59] where do you live btw? [10:59] Sweden [10:59] have you received something since the 1st of July? [11:00] we have had customs and vat + handeling fee since 2018 [11:00] but somehow they passed that [11:00] I guess they are sending it as personal mail [11:00] it looked like they where shiped from Gibraltar [11:00] hum, interesting [11:01] yeah, straight to them mailbox [11:01] lunchbreak over, back to work [11:01] PE2BZ, we'll see what will happen with seeedstudio orders...

[11:02] https://support.jlcpcb.com/article/89-customs-duties-and-taxes [11:03] Great! if they collect VAT, their should be no pb. Thks for sharing. [11:04] I'm in UK and have an order in production at the moment so will see in a week or so but hopefully no extra charges [11:04] I always have to pay VAT for jlcpcb orders [11:05] but I've given permission to DHL to represent me to customs, so it's only a few clicks [11:11] michal_f (~michal_f@17-153-196-109.itvmedia.pl) left irc: Ping timeout: 240 seconds [11:12] I'm fine with paying VAT, but in France it will be a fixed fee if not dealt with by the seller + I guess it will probably trigger customs more often which handling fee (25-30¬) is pricey for a few PCBs...
