[00:01:38] I'm also on team not-a-failure [00:02:32] im about to order crap for my rc heli, should I take extra sets of main and tail blades? [00:03:11] Mathuin: I mean we have all these various sources leaking that it failed hut nobody even leaking the actual agency in charge? [00:03:24] but [00:03:51] ve2dmn: we don't even know that it was a spy sat [00:08:09] We do know it's a classified military payload. [00:08:14] That's ... all we really know. [00:08:27] no [00:08:31] We know more? [00:08:34] we don't even know it was military [00:09:11] we know it was govt, we know it was built by Northrop, we know it was launched by spacex, we know it orbited at least once and we know that it was named zuma [00:09:20] that's literally all we know [00:09:21] That fourth thing I didn't know was known. [00:09:53] Mathuin: it wouldn't have been given a catalog ID if it hadn't orbited [00:12:51] Mathuin: also I guess we know that the NRO denies that it's theirs, but whether or not I believe that is iffy [00:12:59] I believe that they denied it. :-) [00:18:48] Mathuin: quite honestly, all these claims from unnamed sources don't add up much with just about anything else [00:33:00] The fact that everyone goes back to arstechnica and they don't cite where they got it is what makes me sketch [00:49:02] https://78.media.tumblr.com/6b446b4535cb2b1fdfd14f0c84aeeefb/tumblr_p1w4nbMu3m1v9qgbgo1_540.jpg [00:55:25] Fluburtur: order some small rockets and mount them on the sides [00:55:34] Then you'll have an RC attack helicopter [00:55:37] eh [00:55:57] im planning on putting a eurocopter AS 350 squirrel fuselage on it [00:56:21] I mean there is the fennec which is a military version of the squirel but civilian heli sounds nice [00:57:10] I mean https://i.ytimg.com/vi/EYrbmZPKff4/hqdefault.jpg [01:06:26] #KSPOfficial: mode change '+o Distractedman979' by ChanServ!ChanServ@services.esper.net [01:22:56] evening. [03:28:00] The RAMP node script stops at 0.2 because it assumes RCS exists. My engine (the ant) can handle 0.05 no problem. Wondering how to parameterize that properly. [03:28:30] Also wondering if it's worthy of a bug report submission (check for RCS before depending on it for fine tuning) [04:50:54] Pro tip: do not allow your probe to rotate such that the sun cannot hit the panels. [05:30:19] #KSPOfficial: mode change '+o Supernovy' by ChanServ!ChanServ@services.esper.net [05:31:36] Mathuin: wait 0.25 years it'll be fine. [05:33:27] more accurately, 0.25 orbital periods with respect to whatever path / SMA your probe is on around the sun [05:34:44] an eccentric orbit probably still makes that calculation worse than it should be :/ [05:37:50] Mathuin: or is your probe rotating once per year O_O [05:49:43] My probe has panels around the cylindrical axis, but it ended up pointing head on towards the sun :-( [06:07:58] #KSPOfficial: mode change '+o Supernovy' by ChanServ!ChanServ@services.esper.net [06:22:21] Okay, 'lock steering to up.' puts the ship into a spin. Anyone here know how to tell kOS to orient the ship straight up without this crazy tumbling?

[08:50:15] I've never been able to run KSP with all my mods in full res [08:50:39] but now I have 24 GB of RAM [08:52:28] KSS will do that to you xD [10:09:07] A Japanese astronaut has apologised for wrongly stating he has grown 9cm (3.5in) since arriving at the International Space Station (ISS) just over three weeks ago. [10:09:07] Norishige Kanai said in fact he grew by 2cm, blaming "a measurement mistake". [10:10:13] Arynnia: theres only 2 kinds of ram, not enough or not enough to max out ;) [10:13:04] Rolf: I actually appear to be right in the middle [10:13:12] KSP is scraping by right under 100% of usage xD [10:13:17] :) [12:47:46] look at this cat https://78.media.tumblr.com/78d50e91492361e4d6c9bd66c9af5393/tumblr_orui1rC8pi1u6kbs9o1_540.jpg [12:54:14] Disappointing.

[13:01:49] argh [13:01:52] But no, no further comment. I can't always encourage you to post memes ;P [13:02:05] too bad [13:02:19] intestinate fluburtur [13:02:26] btw all the crap I ordered for my heli shipped [13:02:58] Cool [13:03:00] show pics! [13:03:14] I always wanted to have a heli. But it was too expensive and no place to fly it safely [13:03:18] well I ordered it last night [13:03:25] https://www.banggood.com/0_01g-500g-Electronic-Pocket-Mini-Digital-LCD-Gold-Weighing-Scale-Gram-p-1206787.html?rmmds=myorder&cur_warehouse=CN [13:03:39] I guess the most interesting part is this https://www.banggood.com/Aglin-TREX-450-RC-Helicopter-Accessories-325MM-Main-Blade-p-938164.html?rmmds=myorder [13:04:39] or that https://www.banggood.com/Aglin-TREX-450-RC-Helicopter-Accessories-325MM-Main-Blade-p-938164.html?rmmds=myorder [13:04:50] I want to try all kinds of rc stuff [13:05:05] I got planes and multirotors done already [13:05:41] so I have to do: cars, boats, tanks, helis, probably a lot of other stuff too [13:06:36] I still want to build a intermeshing heli [13:06:45] but probably won't be 100% 3d printed [13:06:50] more like 80% [13:52:36] I'm getting flashback from 20 years ago [14:04:56] https://en.wikipedia.org/wiki/Flashback_(1992_video_game) [14:19:54] another fine day has begun. [14:36:50] madmerlyn: I'm scared now [14:37:05] lol why [14:37:09] I'm getting flashback from 20 years ago [14:38:13] I getting flashdance flashbacks now. [14:38:28] WHAT A FEEEEELING.... [14:39:56] Action: Mat2ch covers both ears (err, eyes) [14:39:58] lalalaaaaaaaa [14:40:00] I hear nothing! [14:40:02] i had a demo of it, was called Another World for me, good game [14:40:42] Epi: that's a different game [14:40:50] ^ [14:41:00] https://en.wikipedia.org/wiki/Another_World_(video_game) [14:41:41] ah right, played both- i remember another world had a 2nd name, forgot i guess lol. [14:42:08] I know, because I now have all* the Steam Achivement for that game :D [14:42:21] * Except the secret one [14:42:22] ah it was 'out of this world', see almost identical to 'flashback' :D [14:42:52] Mat2ch I asked my grandma if I could take the car to come to your place tomorrow but for some reason she didn't want [14:42:59] Out of this world is just another world published under a different title for a different market [14:43:45] https://steamcommunity.com/id/ve2dmn/stats/AnotherWorld/?tab=achievements [14:46:39] the demo blew my mind as a kid, looked so amazing. Played it on the Amiga [14:46:57] madmerlyn: 20 years ago, I was in the middle of the great Ice Storm of 1998 [14:47:04] Fluburtur: I can't imagine any reason why. :D [14:47:17] it's 50F outside here right now :D [14:47:20] Epi: It was too hard for me as a kid... yet I found it somewhat easy these days [14:47:27] What's F? ;P [14:47:33] as a kid.. way to hard for me too [14:47:50] Mat2ch: it's like K, except different strokes [14:48:42] It's I+ 2 x - while K is I+ 1x \ and 1 x / [14:48:43] With the difference that K can be easily understood by adding 273,15. ;P [14:50:07] Also, F come from Roman, while K is from Greek [14:51:18] mat2ch F = (9/5)C+32 [14:51:48] Too much for me to do in my head ;) [14:51:52] so 50F = 10C [14:52:59] I use my own mental 'approximate Formula': 82<=>28, 61<=>16, 40<=>04 [14:53:36] lol [14:54:05] it's a 'good enough' estimate [14:54:40] And of course, -40=-40 [14:55:38] which is cold. Very very cold. [14:55:48] you know one could make the argument that fahrenheit's base unit was more logical because water's freezing and boiling points are variable with pressure, while fahrenheit's bromide solution was self-stabilizing temperature [14:56:02] Mat2ch: we call that 'last week's wind chill' [14:57:27] madmerlyn: but that doesn't matter when talking about absolute temperatures. ;) [14:57:48] ve2dmn: I'd be frozen rock solid by now. [14:57:59] well units don't matter when dealing with absolutes, only accuracy [14:58:09] then, you use K [15:00:36] the 233 is cold and 313 pretty hot [15:00:41] *then [15:00:52] *very very very freaking cold [15:01:02] morning Eric, I browsed your github after you posted yesterday, lot of neat python stuff in there [15:02:09] we should just use Norse dark ages units, "It's approximately 'we didn't sacrifice enough slaves to Odin' degrees out" [15:04:56] You do know part of the reason the US didn't go Metric, was that the ship carrying the official Kg at the time of Jefferson was pillage by pirates and never made it? [15:06:12] visual studio [15:06:18] So the US choose between Dutch and British Units instead (Which were the units used by states) [15:06:26] ... gna should press [win] before [15:07:32] ve2dmn: that is a nice story - unfortunatly the truth is that the law contained a 'voluntary' clause [15:08:32] madmerlyn: thanks a lot of started and never finished projects [15:09:15] that reminds me, the reason there were 2 Voyagers is because when they approached Nixon for approval and told him the last time there was a planetary alignment that would allow visiting all the outer planets, Jefferson was president [15:09:26] so Nixon said "we better do 2 then" [15:10:52] What's the distance of Voyage 1 & 2 now? (Relative to the sun) [15:11:31] https://en.wikipedia.org/wiki/Voyager_2 [15:12:02] I believe 2 is beyond the heliopause and 1 is out near it [15:12:18] 116AU for Voyager 2 [15:12:20] I find it interesting that 2 actually launched weeks before 1 [15:15:56] Fluburtur: https://www.youtube.com/watch?v=X_Ch70KkMtE [15:15:56] YouTube - Marble Machine X part 22 - MARBLE DIVIDER [15:16:06] Voyager 2 is also the only probe to visit Neptune or Uranus AFAIK, it's a shame we can't fund exploration enough to do more out there [15:17:24] I wonder if it's possible to do 'on the cheap' with a solar sail as propulsion [15:21:59] I know the planetary society had a Cubesat solarsail deployement test, but I didn't follow what happened with the project [15:22:49] the Japanese solar sail project has no info beyond it was supposed to wake up from hibernation like 2 years ago that I've been able to find :/ [15:22:55] IKAROS or whatever [15:23:16] clever name [15:23:43] from wiki JAXA expects the 5th wake up of IKAROS in the northern hemisphere winter of 2016. [15:23:54] and when I went to the JAXA site there was nothing except that same info [15:25:11] apparently it achieved all of its scientific primary objectives back in 2010 though so maybe they just stopped signaling it [15:26:31] or it never came back online and they just didn't want to talk about it, lol [15:26:47] https://en.wikipedia.org/wiki/LightSail_2 [15:27:00] Gonna be launch as secondary payload on Falcon Heavy [15:27:20] or be part of a big fireball! [15:27:50] either way, it should be interesting to watch [15:27:55] hmm anyone familiar with unity ... will it cost performance if I add a transform to the game object I export as .mu for the game? [15:28:07] wait.. on the test launch? [15:28:20] no. STP-2 [15:28:23] ah [15:28:29] so, Test launch #2 [15:28:42] My model was to big so I wonder if I should import a rescaled version in Unity to export a new .mu [15:28:53] apparently they sent 1 up already and it failed, went up on an ELA launch [15:29:00] err ULA [15:29:44] that's the great thing with cubesats though, they're cheap [15:30:00] well relatively speaking heh [15:30:09] PS losing the first one isn't a major setback though [15:31:59] anyway. SpaceX says they'll launch FH soon after their static fire test at the end of this week [15:32:07] What's your bet? I say Sunday [15:32:30] so according to that LightSail wiki it's actually going to be the third FH launch? [15:32:42] oh nvm [15:32:47] learn2read merlyn [15:35:45] https://78.media.tumblr.com/8b8ad2d7132c681738daa5d5e73bda7f/tumblr_njdppiKTDK1u4nbmvo1_540.jpg [15:36:36] madmerlyn: btw, I think I have enough notes to make a 'test' Rendez-vous script tonight [15:37:06] nice [15:37:36] I tried to do some work on my Mun base last night, but game decided it was going to be an 'everything lags for no reason' kinda night [15:37:49] The logic is simple enough, but I just want to be sure the script doesn't do anything stupid like leave the SOI or make the PE lower then the ground [15:37:54] even relaunching the game it was running poorly, I just ran a full package update on pacman and shut the computer off at that point heh [15:38:18] Blame Meltdown? [15:40:52] lol [15:40:56] Mat2ch https://www.youtube.com/watch?v=X_Ch70KkMtE [15:40:56] YouTube - Marble Machine X part 22 - MARBLE DIVIDER [15:41:03] I dunno, it had been at least a week since my last kernel update [15:41:26] I don't do a pacman update every day anymore, usually about once a week [15:42:10] I did compile an update for discord off AUR without rebooting prior to launching KSP so maybe something got gummed up there with the old version still being in cache or something I dunno [15:42:18] I was tired and didn't feel like investigating [15:42:23] if it's slow again tonight I'll dig around [15:45:37] madmerlyn: https://www.epicgames.com/fortnite/forums/news/announcements/132642-epic-services-stability-update [15:46:36] yeah I've read it affects CPU intensive backend services the most, so servers are having the worst time of it [15:47:21] the more context switches, the worst the impact is [15:49:00] because what the patches do is flush the entire cache eveytime the control goes from the Kernel to a User process [15:49:49] in the case of a virtual machine, everything is a 'user process' to the Hypervisor... [15:50:17] yeah I'm not sure how the patch is/will affect my system at home [15:50:31] it's an arch install so I don't have a lot of unnecessary stuff installed [15:51:10] mostly just the base system, + Gnome and deps, a few things for programming, and games [15:54:20] it's less about what's installed and more about what's running. If it makes a lot of system call, it might impact the performance [15:54:57] well of course, but I'm saying there's nothing unnecessary there so shouldn't be a lot of stuff running [15:55:08] right, sorry [15:55:10] beyond the usual stuff for the desktop, networking, etc. [15:55:26] gotta wonder how games consoles will cope. [15:55:50] it's not like youo can do a quick upgrade, and you can bet several titles are already running right up against hardware limits. [15:55:51] technicalfool: probably won't patch [15:56:11] it's only an issue if you can run 3rd party code [15:56:20] Hah, and leave a hole open for people to potentially run arbitrary software on? On a games console? [15:56:48] after the PSN hack years ago consoles became even more locked up than they were before [15:56:49] yeah, isn't "you can run whatever you like with elevated privileges" the whole point? [15:57:06] even though the hack didn't come from a PS, network security became a huge focus for them [15:57:15] So The'll wall-up the system even more. Like not being able to run unsigned code that isn't from 'the online market-store-place-thingy' [15:57:39] But that's already the case. [15:57:50] expect more of the same [15:58:07] TBH I'm kinda disappointed in MS for not capitalizing on that, PSN was in shambles after the hack and yet here we are in 2018 with Sony leading the pack again [15:58:28] it's MS. They don't know what to do when they don't have a 98% monopoly. [15:59:00] after the hack I believe PSN was completely offline for an entire quarter [15:59:49] like how did that not translate into MS becoming the only console worth buying, that was also around the time that Sony pulled Linux support from the PS3 and shafted a whole bunch of people who were into that [16:00:07] so much bad press and all they could do was Kinect? [16:00:22] technicalfool: MS of 2001 is IBM of 1984. Giant companies used to being too successful that they lost the agility to move quick [16:00:34] it's like they were trying to score the Wii crowd, when they should've had their sights on the super pissed off PS crowd [16:01:42] hah, Kinect was not exactly a stellar launch either. It was going to be a high tech item that could determine exactly which finger you were holding up to it. What ended up being released was a crappy overpriced webcam with most of the work being done on the Xbox. [16:02:05] and then trying to insist people use Kinect. Like no. [16:02:25] they further bungled it by trying to kill the secondhand market with Xbone [16:02:37] something they had to completely scrap before launch [16:02:47] oh there's a bunch of companies and people trying to kill second hand games. [16:02:55] instead of focusing on competition they were aiming at all the wrong markets heh [16:03:12] I have to find that video again... "OUR Sails are not high enough! If we drop the connect, you could Sail higher!" [16:05:04] https://www.youtube.com/watch?v=o-8DNL2wFLY [16:05:04] YouTube - Console Wars - PS4 | Flashgitz | MASHED [16:05:13] all they had to do to properly go "diskless" is go to a cartridge system not unlike the Switch for physical distribution to those people who have consoles in their middle of nowhere cabins, and unveil an online marketplace that would allow anyone to sell their digital purchases [16:06:00] MS could take a 5% cut on any transactions that way, let the users completely determine the secondhand value of the game, and no one feels like MS is just trying to force them into the $60 pricepoint [16:06:37] could even enforce like a 3 month restriction on new releases [16:07:14] would've allowed their design goal of diskless and provided a better platform for digital distribution without all the fallout of attacking the secondhand market [16:07:34] Gamestop would've been pissed, but who cares lol [16:08:55] the only real red flag I would see with a platform like that is people getting their accounts hacked and their libraries liquidated [16:09:38] but if games could only be sold for non-transferrable account credit that removes some of the impetus for doing that beyond just grief [16:11:46] eh, I'd avoid company scrip, myself :P [16:12:23] I don't own either consoles because I prefer Pc gaming anyway [16:12:43] playing an FPS with a controller is... HERESY! [16:12:53] or just plain stupid [16:13:09] or... the only option [16:13:23] because not everyone has a KB/mouse attached to their playstation. [16:13:28] but things like Super Meat Boy is unplayable without a Controller [16:14:51] I have an Xbone, there's no masterrace, we're all gamers :D [16:15:12] technicalfool: people can do what they want, but I would rahter not play a FPS then play with a controller. [16:15:13] also, I prefer FPS on controller [16:15:20] HERESY! [16:15:25] ergonomics [16:15:38] TV must be nice though [16:15:46] having my hand locked onto a mouse near constantly is just yuck [16:15:50] oh youo can prefer an FPS on a controller. You'll just not do as well as an equally skilled player using a mouse. [16:16:01] in a game like KSP I have the accuracy of the mouse but I don't have to have a deathgrip on it to be competitive [16:16:52] though I fail to see the difference between having a deathgrip on a mouse, and having a deathgrip on a controller. "Nintendo Thumb" is not something induced by gripping mice. [16:17:09] Xbox controller is actually rather comfortable [16:17:19] I do have one, yes. [16:17:43] (and a PS4 controller) [16:17:57] (the Kinect can stay in its box) [16:18:15] maybe it's a personal thing, but I can hold an Xbox controller for 2 hours without any discomfort, 2 hours playing Battlefield or soemthing on PC with a mouse and my wrist hurts [16:18:24] Mat2ch looks like my custom chargung board works [16:18:40] now I need to isolate it with hot glue and glue all that to a board [16:19:14] some electronic grade foam would be better for isolation than hot glue [16:19:31] tell that to Apple. [16:20:29] madmerlyn you know me [16:21:00] hot glue has a tendency to drift when it gets hot :P [16:21:07] electronics often get hot [16:21:55] eh [16:21:59] this wont get hot [16:22:14] I don't think I'll get a PS4 or XBone any time soon. I can't think of any exclusives that would fit my playstyle [16:22:18] drift [16:22:29] did you know that the record of contuinous drifting is 8 hours [16:22:44] I want to see the wheels after that [16:22:44] but is it multi-track train drifting? [16:22:45] start with monster truck tires, finish with bike tires? [16:22:49] and they refilled the tank in the middle [16:23:06] https://www.youtube.com/watch?v=obkLDeO58Wo [16:23:06] YouTube - Watch the ALL-NEW BMW M5 refuel mid-drift to take TWO GUINNESS WORLD RECORDS" titles [16:23:20] this is almost kerbal [16:23:27] how do you refuel a vehicle that is constantly moving in a state of low traction? [16:23:43] with an other one [16:23:47] doing the same [16:24:47] well it would be a BMW wouldn't it? [16:25:05] *sigh* I think the median age on subreddit has declined this year. How does a post "Am I the only one that things that the interior of the pods looks cozy af??" have 13 upvotes [16:25:19] that's the definition of low effort posting [16:25:52] also there are various videos showing people climbing out of windows or doors or whatever and controlling a drift while walking alongside the car. There is of course also a wonderful video showing someone doing that and then getting dragged under the wheels. So it's not exactly safe, but definitely possible to up-end a jerry can into the tank while driftintg. [16:30:16] according to this, I should be doing my gravity turns at 1km altitude with a pitch of 30 degrees, that's pretty insane [16:30:19] https://www.reddit.com/r/KerbalSpaceProgram/comments/7p9pht/i_used_krpc_to_perform_over_300_automated/ [16:30:36] that sounds wrong unless you're flying a spaceplane. [16:30:57] 300 automated launches with 1.69 TWR aerodynamic rocket [16:30:58] oh, 30 degrees from vertical? [16:31:04] I'm guessing so [16:31:07] in which case that's probably about right. :P [16:31:15] 30 degrees at 1km seems really early to me [16:31:23] nah, not since 1.0 [16:31:25] I'm lucky if I'm doing 5 degrees at that point [16:31:49] guess I could do some sounding of my own now that I know kOS heh [16:32:16] could increase payload capacity on the launches I can't fit in a mk3 [16:32:37] ha, he had an TWR of 1.69 [16:32:45] my rocket have usually lower TWR [16:33:16] I usually aim for 1.5 or so, sometimes I'll have more pad TWR if I'm using SRBs or something on first stage [16:33:38] like it might be 1.9TWR on the pad, but after 40s it drops down to like 1.3 when I stage the SRBs [16:35:40] more data is needed [16:36:35] I don't use the SpaceY liquid engines much but I love the SpaceY SRBs for first stages [16:36:44] Mat2ch https://cdn.discordapp.com/attachments/186186471202357249/400689384359329793/DSC_8167.JPG [16:36:56] I use the NFE the most, I don't have NFLV though [16:37:04] intelli bi power [16:37:28] depending on the weight etc. I'll either use a stock engine or a NFE engine, generally if I want it to be cheaper I go stock, if it's going to be recovered I go NFE [16:37:36] or if it's going to be reused a lot [16:37:41] like an orbital tug [16:38:31] that battery doesn't look like a joke :P [16:38:34] at least not orbital thug :) [16:38:48] yeah [16:38:52] 4s 2.2 amps hours [16:41:04] so I wonder if putting a very lightweight bell on a baking soda bottle rocket would provide any significant thrust gain over the default ~22mm "nozzle" [16:41:33] the shape of the bottle itself kinda provides its own CD scheme [16:44:32] or maybe instead of baking soda and vinegar I should go straight to alcohol and air :O [16:45:19] I could rig up an igniter with an old spark plug I'm sure [16:46:59] Hey folks - anyone seens issues with new KSP installations from Steam on Windows 10? [16:47:20] new install? [16:47:21] none that I've heard of [16:48:06] Yeah, new install. Ran fine on the laptop before, but it's been reimaged since then. Works fine on my Arch Linux system. [16:48:58] I've tried backrevving to 1.30 and 1.22, but they both seem to have problems, which makes me think it might be a graphics driver or possibly new hardware issue. Thought I would ask just in case there was something going on with the latest build. [16:49:00] I have both Ubuntu and Win10. Runs fine for me... [16:49:05] I have troubles any time I launch with steam overlay on [16:49:12] it makes my KSP crash a lot [16:49:35] I just launch directly from executable instead of through steam [16:50:42] I tried that a couple times without much luck. I would just install Arch or Ubuntu on there but they don't handle Bumblebee/Optimus very well, even now [16:51:22] Maybe that's more of a user problem though. [17:00:07] Fluburtur: it makes me a bit happy to see it's still getting used [17:00:15] yeah [17:00:20] it was in my friend's basement [17:00:29] I will give him back his charger then [17:00:38] but yours doesn't count the mah refilled sadly [17:01:08] I thought it does [17:01:29] I will have to make sure [17:03:06] uh yeah im discharing a battery and there is a counter on the top right I think it's mah [17:03:12] but doesn't do mah for each cell [17:03:38] #KSPOfficial: mode change '+o Deddly' by ChanServ!ChanServ@services.esper.net [17:06:02] oo you could do butane with soda like cocacola, if you have a right to flip it quickly [17:06:10] rig* [17:21:37] Fluburtur: could the other do that? [17:21:43] yeah [17:21:57] becaue it doesn't use the main leads for charge, only the balance leads [17:21:59] woah. It must have discharged through the balancer then [17:22:09] but since yours has a separated balance board it can't [17:22:52] yeah. I bought mine one year too early :| [17:23:01] heh [17:23:12] the version released the year after had the balancer integrated [17:23:13] well at least it works [17:23:41] I bought it at a time where LiPos weren't that common yet. [17:23:43] how old is that charger even [17:24:04] Do you really want me to take a look at very old invoices? ;P [17:24:49] eh just the approximate year will do [17:25:36] also when I select the discharge option does it discharge it to storage level? [17:28:53] 2007? 2008? [17:29:24] No, it discharges it to a voltage. Iirc this is configurable [17:29:58] eh [17:30:06] I only found the discharge amp [17:30:13] and battery type [17:30:20] guess I will have to go get the manual [17:30:40] well, it's ten years when I read that manual [17:30:49] And I'm not sure if I ever used the discharge option at all [17:31:29] I rarely fully discharge the batteries when using them [17:31:38] The LiPos back then were very sensitive [17:31:39] and not patient enough for using the lamp [17:32:13] there's no memory effect in lipo accumulators [17:32:28] doesn't matter if you charge them at 33 % or at 50 % [17:32:50] eh [17:32:58] it damages them to leave them charged a long time [17:33:02] I killed a few like this [17:33:49] #KSPOfficial: mode change '+o Badie' by ChanServ!ChanServ@services.esper.net [17:34:55] eh, other way round. Best storage capacity is around 75 %. They dislike it a bit more to store them at 100 %, but if you store them too low their self-discharge will destroy them definitely [17:35:10] eh [17:35:17] apparently 3.7v is best [17:35:26] and put them in the fridge [17:46:57] Fluburtur: https://www.propwashed.com/lipo-storage-voltage/ [17:46:59] long read [17:47:02] but worth it [17:47:14] alright I will look at that [17:48:45] also the paper he cites is about Li-Ion which imho can't be directly applied to LiPos [17:49:22] I guess li-ion are made to last long when charged [17:49:39] otherwise im in a abd situation becaseu the ones in my mini wing have been charged for like a month [17:49:42] Eh, the paper he cites begs to differ :) [17:49:56] but it's only a fraction [17:50:15] I hate the internet for not having good sources for their claims [17:50:32] everybody is talking about the lipo storage charge, but nobody has any data to verify those claims [17:50:45] and many are just writing what they have heard somewhere [17:51:06] well they come from the factory at 3.7 so I trust that [17:52:03] if you're producing lots and lots of lipos... would you sell them fully charged or sell them at a minimum charge level to save energy/money? ;) [17:52:38] I guess they put it at that level for safe storing and transporting [17:52:57] actually I don't think the cost of electricity is the issue, batteries, even lithium ones are more stable when charged around 50%, they ship them partially charged because of that [17:53:03] and I know that keeping batteries fully charged have killed a few of mine too so I wouldn't do that [17:53:17] this is according to my former boss who worked in EE for like 30 years [17:53:40] true. [17:54:17] Fluburtur: how long do you store your accumulators? Month? [17:54:23] flub I'm looking at doing something like this before I do a serious hobby rocket https://www.instructables.com/id/The-Ultimate-Altimeter-A-compact-Arduino-altimeter/ [17:54:32] sometimes a few weeks [17:54:48] except instead of putting it in a case I'll come up with something a little more rocket friendly [17:54:49] looks like a fun project [17:55:00] still shouldn't damage them. Hrm [17:55:01] it's accurate to within 1 ft/0.3m [17:55:16] put one of those 2.4ghz radio modules to talk with a ground station [17:55:21] wonder if I could put some other telemetry on it like a temperature sensor [17:55:55] stick it on a hobby rocket that goes like 100m up and measure the temperature [17:56:18] the temp sensor would have to be exposed to air before chute deployment though [17:57:22] although if the temp sensor and altimeter are both running on the same controller could just have temp sensor exposed and have the device pull like 3 readings after altimeter peaks, that way it gets readings when velocity is the lowest and there's not as much air moving around it [17:58:15] I guess taking readings at a regular interval and calculating vertical speed could be fun [17:58:21] you could do graphs [17:58:26] yes [17:59:19] some of the hobby rockets I'm finding are pretty inexpensive too, but small, I'm thinking I'll be limited on space if I try to pack my telemetry in the nose [17:59:29] otherwise I could try to radially mount it and balance it [17:59:41] make a candy rocket? [17:59:53] and if yu [18:00:10] if you make a ground station with radio link you can get live readings [18:00:18] and backup in case the rocket doesn't survive [18:00:50]
