L100[05:54:13] <TheKosmonaut> A bit of an exaggeration but this is why I can't stand NDT
L101[05:54:20] <Althego> hehe
L102[05:54:29] <Fluburtur> same
L103[05:54:54] <Fluburtur> isn't he a theorical physicist or something?
L104[05:56:46] <TheKosmonaut> Astrophysics, physical cosmology iirf
L105[05:57:32] <Fluburtur> I remember in a video of smarter every day when he was like "a heli cannot fly if the engine dies it will jsut fall" I guess he was kinda playing a role but still
L106[05:57:50] <Fluburtur> and he could tell me about how to cook food but I would still trust my grandma more
L107[05:57:57] <TheKosmonaut> He's definitely smart... But he makes a lot of blunders on Twitter
L108[05:58:31] <TheKosmonaut> Like when he said that bb8 rolling on the sand in Star wars was physically impossible
L109[05:58:40] <Fluburtur> ehhh
L110[05:59:00] <Fluburtur> don't talk about stuff outside your area of expertise neil
L111[05:59:14] <TheKosmonaut> Then the Star wars people in the prop Dept sent him a video of the remote bb8 rolling on the dunes
L112[05:59:18] <Fluburtur> you are a physicist but clearly not a mechanical engineer
L113[05:59:32] <Althego> every famous scientist does that. and it is well known that they all fail when they do
L114[06:01:41] <Fluburtur> he does that pretty often
L115[06:06:29] <Mat2ch> TheKosmonaut: It may depend on the sand
L116[06:06:41] <Mat2ch> and the weight of a BB8
L117[06:06:53] <APlayer> What's a bb8?
L118[06:07:12] <APlayer> (I have not watched Star Wars, so please don't kill me)
L119[06:07:15] <Mat2ch> sand can be rock hard, but also like a fluid
L120[06:07:21] <Fluburtur> a ball version of r2d2
L121[06:07:37] <Mat2ch> APlayer: I don't watch Star Wars either. But it's a rolling ball with a head that stays on top ;)
L122[06:07:37] <APlayer> R2D2 is that robot assistant thingy?
L123[06:07:44] <Fluburtur> yeah
L124[06:07:45] <Mat2ch> yeah
L125[06:07:50] <Fluburtur> that looks like a trash can
L126[06:07:51] <APlayer> Alright, got it
L127[06:08:45] <Mat2ch> and if the ball has a very smooth surface and is heavy and the sand is very fine grain BB8 might really be stuck there
L128[06:09:16] <APlayer> And why exactly would it not be able to roll on sand?
L129[06:09:18] <Fluburtur> he does have a lot of panels everywhere
L130[06:10:20] <Mat2ch> APlayer: because the sand could act as ball bearing
L131[06:10:29] <APlayer> Ah
L132[06:10:42] <Fluburtur> I xould be more worried about wet sand sticking to it
L133[06:10:49] <Mat2ch> mud. :D
L134[06:10:51] <APlayer> Well, I guess that's called "traction" and a whole field of science on its own?
L135[06:11:11] <Fluburtur> yeah
L136[06:11:21] <Fluburtur> we were supposed to learn about that in mechanics but never did
L137[06:12:19] <APlayer> So a rough surface would probably rather be able to roll on sand than a smooth surface
L138[06:12:54] <APlayer> But it also depends on how the sand "flows" in itself and the friction force between the surface and the sand
L139[06:13:01] <Fluburtur> https://blenderartists.org/forum/attachment.php?attachmentid=415466&d=1450685852
L140[06:14:02] <APlayer> Looks pretty smooth to me
L141[06:14:18] <Fluburtur> yeah bit at the joint between panels and stuff
L142[06:14:28] <Fluburtur> I mean as long as it doesn't sing too low in the sand it should be fine
L143[06:14:48] <APlayer> But still, the panels could have any sort of properties
L144[06:15:20] <APlayer> I don't think a normal steel ball of this shape could roll on normal sand, but given special circumstances, why not?
L145[06:16:11] <Gasher[work]> steel ball yeah, but sphere :)

L147[06:16:29] <APlayer> Given that such a thing would probably have been manufactured with extra traction (that's it's main propagation method, isn't it?) and Star Wars is science fiction, the panels could be made from any sort of grippy material
L148[06:16:48] <Fluburtur> rubber paint?
L149[06:17:05] <APlayer> Something like that
L150[06:17:11] <Fluburtur> but it looks and sounds very metallic in the movies
L151[06:17:13] <APlayer> Though it has to be durable
L152[06:17:19] <Fluburtur> like only a thin layer of orange paint at most
L153[06:17:59] <APlayer> Perhaps it is able to move its panels slightly in such a way that they scoop up sand?
L154[06:18:06] <Fluburtur> yeah
L155[06:18:11] <Fluburtur> that would probably do it
L156[06:18:25] <Fluburtur> then it would be full of sand
L157[06:19:19] <APlayer> Well, of course it would not allow the sand to actually get inside

L193[06:51:27] <Deddly> http://store.steampowered.com/app/352700/Subspace_Continuum/
L194[06:51:38] <Deddly> I've never come across something so addictive.
L195[06:51:53] <Deddly> As they say: easy to learn, but takes a lifetime to master.
L196[06:51:53] <TheKosmonaut> Oh. That game
L197[06:52:00] <TheKosmonaut> Like PvP asteroids
L198[06:52:21] <Althego> tried factorio? some say it is really addictive
L199[06:52:26] <Deddly> Yeah, you could put it that way
L200[06:52:34] <Truga> more like cracktorio
L201[06:52:44] <Ezko_> heh that's funny Truga
L202[06:52:51] <Deddly> KSP players seem to appreciate a game with longevity, so I thought maybe there would be some players here
L203[06:53:12] <Deddly> I've been playing that for 16 years, on and off
L204[06:53:27] <Ezko_> strange that i've never heard of it before
L205[06:53:47] <Ezko_> well gotta try some time
L206[06:54:07] <Althego> my last n2o canister is is empty now. gone. along with the cream that was in it
L207[06:54:09] <Deddly> Just be aware that each zone is like a completely different game
L208[06:54:17] <Truga> factorio is basically
L209[06:54:27] <Truga> "hmm it's friday evening let's make a factory"
L210[06:54:38] <Truga> "what do you mean it's monday morning"
L211[06:54:55] <Fluburtur> Althego did you make a rocket with it
L212[06:54:57] <Althego> what do you mean flash gordon approaching
L213[06:55:05] <Althego> no, i ate it
L214[06:55:20] <Fluburtur> no2 is really good oxy
L215[06:55:25] <APlayer> LOL, it /is/ edible
L216[06:55:34] <Truga> as a bonus, someone made a mod for factorio that converts rocket parts you make in factorio to extraplanetary launchpads rocket parts
L217[06:55:35] <Deddly> Subspace Continuum is more like: "Damnit I'll get that guy this time. OK, THIS time. Wait, I know what I'm doing wrong. OK, THIS time. One more try. How did he do that??"
L218[06:55:37] <Althego> n2o
L219[06:55:44] <APlayer> It's N2O, though
L220[06:56:19] <Althego> not written on it anywhere that it uses n2o. but to my best of knowledge cream uses that for gas
L221[06:56:32] <Ezko_> what food should i make today
L222[06:56:38] <APlayer> I thought they used N2
L223[06:56:56] <Fluburtur> I should buy stuff from amzon and make a rocket with it
L224[06:56:57] <Althego> maybe latley it is n2

L260[07:12:45] <JCB> careful with the cooling system.. was talk about temprature diferentials in metals and joints.
L261[07:13:22] <Althego> obviously the cooling of the nozzle alone is worth several books
L262[07:13:48] <Althego> rocket science is easy. rocket engineering is hard
L263[07:14:35] <Gasher[work]> i have tungsten, but a small piece
L264[07:15:08] <Althego> also a really hard material, not really workable with the usual methods
L265[07:15:23] <Gasher[work]> what
L266[07:15:50] <Gasher[work]> that piece i have is alloy and it is machinable
L267[07:16:04] <Althego> "In its raw form, tungsten is a hard steel-grey metal that is often brittle and hard to work."
L268[07:16:33] <Althego> ok it also says if it is very pure you can do stuff with it
L269[07:16:42] <APlayer> Tungsten on its own is brittle, you need to mix stuff into it to make it softer
L270[07:16:52] <Gasher[work]> it's not raw, as i said it is alloyed but i don't know which alloy exactly it is
L271[07:17:19] <Gasher[work]> i guess it would be the one that gets harder after temperature treatment
L272[07:17:49] <APlayer> I wonder, though, if you coat tungsten with ceramic on the outside, wouldn't that make a rather strong vessel to contain, say, a reactor core?
L273[07:18:05] <JCB> just 3d print it..
L274[07:18:10] <JCB> oh wait... doh
L275[07:18:34] <Althego> combining different materials can be tricky because of thermal expansion

L285[07:21:32] <Iskierka> more tungsten carbide would work better than a ceramic layer
L286[07:21:51] <APlayer> Alright, tungsten carbide with titanium?
L287[07:22:54] <Iskierka> titanium isn't magic and if this was space-limited tungsten carbide would be better than almost everything else due to density
L288[07:23:15] <Iskierka> if mass limited then due to the likely cost to begin with you're probably better off with inconel
L289[07:23:19] <Althego> you cna also try silicone carbide and obron nitride for hardness
L290[07:23:35] <Althego> maybe al2o3 too
L291[07:23:38] <Iskierka> I'm not sure why a reactor would need hardness anyway
L292[07:23:56] <Althego> dunno

L333[08:24:28] <darsie> I'd say.
L334[08:25:02] <darsie> In Fukushima we got H2 from zirconium and hot water, IIRC, which caused the hall to explode.
L335[08:25:03] <APlayer> Perhaps "Magnesium does not react with water to any significant extent" means that it does not produce significant amounts of Mg(OH)2?
L336[08:26:04] <darsie> We have a magnesium electrode in our water boiler.
L337[08:26:15] <APlayer> I.e. it wouldn't do what alkali metals usually do in water
L338[08:26:27] <darsie> Maybe at 300 C.
L339[08:26:35] <APlayer> However, if it is already burning...
L340[08:26:47] <darsie> Might burn in steam.
L341[08:26:53] <APlayer> I guess it /would/ reduce water and produce hydrogen

L417[09:10:03] <Eroc|2> I'm wondering, I built a station module using InfernalRobotics for some double folded Solar Array Beams. Each held a ton of solar array the 1x6 standard modules. Starting the module went fine, deploying them worked as intended
L418[09:10:55] <Eroc|2> yet as I returned to the Station the Kraken had taken a hold of the solar arrays and they were spinning around violently exerting enormous torque on the station
L419[09:11:23] <APlayer> Reload from a quicksave
L420[09:11:47] <APlayer> IR contraptions are prone to Kraken attacks indeed
L421[09:12:04] <Eroc|2> so do a F5 - F9 and hope for the best?
L422[09:12:19] <APlayer> Uh, no F5
L423[09:12:31] <APlayer> Revert to an earlier stage
L424[09:12:46] <Eroc|2> there was now previous quicksave so ... nothing to go back to
L425[09:13:08] <APlayer> If that is impossible, try switching to KSC and back to the station
L426[09:13:33] <APlayer> Even if that fixes the spinning, there might be damage, check things carefully
L427[09:13:40] <APlayer> And quicksave when using IR
L428[09:15:00] <Eroc|2> okay ... Thanks for the tips.
L429[09:15:44] <APlayer> If that does not fix the spinning or the spinning comes back again, a screenshot of the station would be helpful in finding the issue
L430[09:16:12] <APlayer> In the worst case, replace the IR modules with conventional ones
L431[09:16:29] <Eroc|2> Quicksave is a little bit problematic as I do often several long time missions parallel - I saved the station this time by decoupling the module and getting it to a deorbit trajectory
L432[09:16:50] <APlayer> Humm, I see
L433[09:17:27] <Eroc|2> whicha shame for the expensive life support modules on it - but that is the price of exploring space - with a ton of mods :D
L434[09:17:55] <Eroc|2> better then giving up the whole station
L435[09:19:32] <APlayer> Well, I guess just try to avoid using IR in weird places, the mechanics circumvent a lot of internal KSP stuff which leads to random bugs
L436[09:20:06] <APlayer> And if things break, consider it a component failure and abort the mission :P
L437[09:20:31] <Eroc|2> yeah probably IR should be limited to short fun stuff but not in creating elaborate foldable space-stations

L441[09:23:21] <Iskierka> those tend to be simple enough (and built with folded as default) that they don't glitch out

L454[10:16:29] <Mathuin> Back from driving the wife to work. Now to see what's wrong with my circularization script.
L455[10:16:43] <Mathuin> Also, kOS lets you print at a particular point -- how can I tell where the next print will be?
L456[10:19:47] <Mathuin> So my vis visa equation gives me the following results: Pe V is computed to be 7731m/s, Ap V is 1137.7, delta between is 6593, burn time of 59 seconds.
L457[10:20:18] <Mathuin> When I create the node, the game says that's a 103 second burn and that my Pe will be -496k instead of 100k.
L458[10:21:43] <umaxtu> are you using RSS?
L459[10:21:49] <Mathuin> No RSS/RO here.
L460[10:22:23] <APlayer> The node does not account for burning off fuel, indeed
L461[10:22:37] <umaxtu> maybe try installing the better burn time mod?
L462[10:22:50] <Mathuin> It is installed, I think that's what's telling me 103s
L463[10:22:52] <APlayer> Rely on vis viva
L464[10:22:56] <Mathuin> I'm trying to do the math in kOS.
L465[10:23:07] <Mathuin> Is 1137 m/s a reasonable value for orbiting at 100km ?
L466[10:23:14] <Mathuin> s/orbiting at/orbiting Kerbin at/
L467[10:23:22] <APlayer> Uh, rely on tsiolkvsky, that is
L468[10:23:48] <APlayer> Well, usually it is 2200 m/s, IIRC
L469[10:24:08] <APlayer> But given the PE velocity, I'd assume this is not an orbit yet
L470[10:24:26] <Mathuin> It's just after the gravity turn, for context.
L471[10:24:39] <APlayer> Yeah, this is a suborbital trajectory
L472[10:24:50] <APlayer> The periapsis is below the surface
L473[10:24:55] <Mathuin> That is correct.
L474[10:25:17] <APlayer> So if you managed to get there and not crash into Kerbin, your orbital velocity would be 7731 m/s
L475[10:25:21] <Mathuin> For v=sqrt(gm(2/r-1/a)) is that r and a from my target orbit or my current one?
L476[10:25:35] <Mathuin> Yes, if there were a giant burrito sized tube through the planet, I would be zooming along at that speed. :-)
L477[10:25:39] <APlayer> And you pretty much don't care about the PE velocity at this point
L478[10:26:05] <APlayer> What you need is the AP velocity and the velocity at the same spot if the orbit was circular
L479[10:26:17] <Mathuin> Mmm.

L481[10:26:23] <APlayer> The difference between those is the burn you need to perform
L482[10:26:36] <APlayer> You follow me?
L483[10:26:41] <Mathuin> No.
L484[10:26:52] <Mathuin> I have the AP velocity and PE velocity for the orbit I am in.
L485[10:26:55] <APlayer> So, you are at AP on a suborbital trajectory
L486[10:27:03] <APlayer> But your target is a circular orbit
L487[10:27:08] <Mathuin> Yes.
L488[10:27:22] <Mathuin> "the velocity at the same spot [where, AP?] if the orbit was circular"
L489[10:27:30] <APlayer> Now, you need to see what the velocity at AP /already/ is, because that's what you already have
L490[10:28:18] <Mathuin> "I have the AP velocity ... for the orbit I am in."
L491[10:28:23] <Mathuin> That makes sense, and I have it.
L492[10:28:24] <APlayer> And to find out what you lack, you also need to know what your goal is, i.e. the velocity of a circular orbit that the same altitude
L493[10:29:29] <APlayer> This is obtained from the circular orbit vis viva simplification you will find on Wikipedia (or really, just derive it yourself, where a = r)
L494[10:30:57] <APlayer> Got it?
L495[10:31:10] <Mathuin> I already think I understand the vis visa equation.
L496[10:31:12] <Mathuin> THe problem is the inputs.
L497[10:31:49] <Mathuin> I have modified my script to return the current ap velocity (1137ish) and the necessary velocity from an orbit with that same altitude and a semimajor axis equal to twice the sum of the apoapsis and radius, which now that I think of it is too much.
L498[10:32:12] <Mathuin> The resulting node is 1613ms and will result in an ap of 150k and a pe of 100k.
L499[10:32:15] <APlayer> No, it's correct
L500[10:32:28] <Mathuin> "semi" means half, does it not?
L501[10:32:38] <APlayer> (AP + radius) * 2
L502[10:32:42] <Mathuin> The entire axis is apo plus radius plus radius plus apo ?
L503[10:32:47] <APlayer> Uh, let me see

L507[10:33:09] <APlayer> Yep, sorry
L508[10:33:11] <APlayer> Only once
L509[10:33:15] <Mathuin> 1137 to 2246 requires 1108 which I have
L510[10:33:20] <Mathuin> burn length is 20s which is reasonable.
L511[10:33:28] <Mathuin> So I think circularization is a win.
L512[10:33:35] <Mathuin> Now to see if execute node will burn such a thing.
L513[10:34:02] <Mathuin> I have a v. narrow window here to try things before reverting to launch again.
L514[10:34:05] <Mathuin> Since I didn't save.
L515[10:34:40] <Mathuin> The execute node script has an error in the first line, sigh.

L532[10:44:54] <APlayer> Well, PID loops are the "proper" way to do a lot of things, but I avoid them when possible, because it's so difficult and time consuming
L533[10:45:11] <APlayer> PD loops are somewhat easier and usually do fine too
L534[10:45:44] <Mathuin> Does that work by setting kI to zero, or do I need to write it out longhand?
L535[10:45:52] <Mathuin> Because right now I'm looking at a very very simple P loop.

L623[12:17:58] <lordcirth> Mathuin, is she stuck in orbit or what?
L624[12:18:02] <Mathuin> Stuck for now.
L625[12:18:10] <Mathuin> I was going to revert but KSP crashed so I sucked it up.
L626[12:18:59] <lordcirth> Mathuin, how high is Pe? Close enough to 70k to get out and push, or spin decouple?
L627[12:19:23] <Mathuin> 85k, not worth it, will rescue her as a project in writing a rendezvous script, or restart at worst.
L628[12:19:40] <Mathuin> Jeb ascended with the gravity turn script, circularlized with the circularize script and execute node script, and will now hopefully land. I built the node by hand this time, used the execute node script to execute the node, and now I'll fly "by hand" for the landing.
L629[12:21:05] <Mathuin> I didn't think to write a script for landing. :-)
L630[12:22:08] <Mathuin> A variant of the circularize script would create a node with a desired periapsis, say 0. Execute the node, and have the ship drop everything to the heat shield before pointing backwards. I guess?
L631[12:22:32] <lordcirth> "landing" a capsule is usually just lock steering to retrograde. wait until alt < 5000. stage.

L703[13:49:08] <Mathuin> I no longer need "circularize.ks" or "deorbit.ks" now that I have ChangePeri() in my lib file.

L723[13:57:50] <Mathuin> kRPC is something I am super exciteda bout.
L724[13:57:57] <Mathuin> Once he gets gRPC support, I will write things in Go.
L725[13:58:07] <madmerlyn> I want to try it out, but it seems to be a lot less documented than kOS, which isn't highly documented itself
L726[13:58:32] <Mathuin> Stuff like Telemachus is more suited for kRPC.
L727[13:58:39] <ve2dmn> EricPoehlsen: if you like Python, go with kRPC
L728[13:59:06] <madmerlyn> yeah I like the idea of running a python daemon to monitor my ships and then execute applications on them :P
L729[13:59:07] <Mathuin> kOS code runs on a virtual machine within your command probe. kRPC code runs on your desktop and communicates with KSP.
L730[13:59:11] <ve2dmn> Also, kRPC does a lot more operation per second
L731[13:59:27] <ve2dmn> but it's not at the same 'speed' as the simulation
L732[13:59:37] <EricPoehlsen> I do a lot of Python stuff - the reason I have not yet done some KSP mods is that I am shying away from getting to deep into C#
L733[14:00:02] <Mathuin> I am very good with Python, OK with Go, and know nothing from C# other than I've used to fix bugs in KSP mods.

L797[14:21:27] <madmerlyn> basically it's like if(engine:STATE=FLAMEOUT){STAGE.} or something like that
L798[14:22:04] <madmerlyn> but you have to get all your engines in a list and iterate over them for it to work

L847[14:36:03] <madmerlyn> I want to see some pastebins of yall's scripts
L848[14:36:23] <madmerlyn> let's start an IRC kOS brainstorm
L849[14:36:35] <Mathuin> madmerlyn: I have been brainstorming in this channel on kOS for the past two days. :-)
L850[14:36:43] <ve2dmn> Aplayer would want to be in on this :D
L851[14:36:55] <Mathuin> And APlayer has indeed participated.
L852[14:37:08] <EricPoehlsen> I think I'll put them on github once they are more than just some ascent auto-path
L853[14:37:24] <ve2dmn> I'm a sysadmin, not a dev... so I make crappy mistakes for lack of better coding practice.
L854[14:37:44] <madmerlyn> I'm trying to transition to developing
L855[14:37:46] <Mathuin> I'm doing more devvy stuff, since most of the sysadmin work isn't very interesting lately.
L856[14:38:05] <Mathuin> Okay, gravityturn and circularization are sane. landing's next.
L857[14:38:23] <ve2dmn> Mathuin: we are moving towards DevOps... so I'm gonna have to adapt
L858[14:38:26] <madmerlyn> goooood luck buddy
L859[14:38:44] <madmerlyn> I spent like 5 hours landing on the launchpad, and while I was ultimately successful, wasn't very cost effective heh
L860[14:39:00] <Mathuin> My definition of landing is Jeb walks away. :-)
L861[14:39:19] <ve2dmn> madmerlyn: I would not know where to start doing that... because I cannot even guestimate the air loss
L862[14:39:45] <EricPoehlsen> that reminds me I wanted to calculate the possibility of accidently landing at KSC
L863[14:40:17] <madmerlyn> if you have a mod that has grid-fins it helps
L864[14:40:24] <madmerlyn> and trajectories of course
L865[14:40:32] <madmerlyn> kOS has hooks for trajectories
L866[14:40:39] <ve2dmn> madmerlyn: I did not know that
L867[14:40:45] <EricPoehlsen> because some days ago I had some mishap in getting a space-station into orbit - or better something exploded on decoupling and I nearly lost Jeb
L868[14:41:07] <EricPoehlsen> but somehow I managed to deorbit his capsule with the rcs
L869[14:41:29] <EricPoehlsen> and miraculously ended up 50 meters from the launchpad
L870[14:41:49] <madmerlyn> I want to kOS autopilot a landing on the KSC runway, but I'm not sure how to solve it programmatically yet
L871[14:42:05] <madmerlyn> I'm just getting to the point where I can do it consistently the same way manually
L872[14:42:13] <ve2dmn> EricPoehlsen: if you are in 0 inclination, take the size of the KSC and divided by the circumference of Kerbin
L873[14:42:50] <madmerlyn> there's still going to be some inaccuracy though because even the best kOS script isn't going to get in an absolute perfect 0 inclination
L874[14:43:05] <madmerlyn> mine usually ends up in like 0.04+ inclination
L875[14:43:14] <EricPoehlsen> ve2dmn: I thought it will probably be somewhere inside the 1:10000 range +-
L876[14:43:19] <ve2dmn> I want an auto-dock
L877[14:43:40] <ve2dmn> so I can automate supply runs to my Kerbin space station
L878[14:43:53] <madmerlyn> I wonder if kOS has hooks for docking port alignment, not that that's required but it might simplify the math
L879[14:44:17] <EricPoehlsen> 1km is roughly 1:2000 of the circumference
L880[14:44:50] <madmerlyn> Kerbin is only 2000km around the equator? Surely it's bigger than that.
L881[14:45:10] <EricPoehlsen> double that
L882[14:45:20] <EricPoehlsen> 600 km radius not 300km radius
L883[14:45:21] <ve2dmn> most of my brain power has been spent trying to come up with clevers ways to launch with minimal dV
L884[14:45:29] <ve2dmn> the result is https://github.com/ve2dmn/kOS-Script/blob/master/launch4.ks#L109-L113
L885[14:45:35] <madmerlyn> yay a script
L886[14:45:55] <ve2dmn> madmerlyn: I have a whole repo
L887[14:46:22] <ve2dmn> Like I said, I'm no coder... but the thing gets into orbit.... sometimes
L888[14:46:58] <madmerlyn> when I get home I'll share my spaceplane script
L889[14:47:09] <ve2dmn> That script try to estimate the loss due to everything... then it forget about it and simply uses the current groundspeed
L890[14:47:22] <madmerlyn> though it's less calculating ideal ascent and more, ascend the same way every time you run it heh

L892[14:48:07] <ve2dmn> And the throttle adjusting should be a PIDLoop
L893[14:48:16] <ve2dmn> right now it's... commented out
L894[14:49:00] <madmerlyn> mine spaceplane ascent is more along the lines, when you're going 120m/s pitch 10 degrees, when you're at XX altitude do this, kinda deal
L895[14:49:33] <madmerlyn> with a fun little parameter that can be set to use nose-thrusters to lift the nose up on my mk2 planes that have the landing gear too far back to pivot
L896[14:50:18] <madmerlyn> my Lancelot Mk2 plane I just don't feel comfortable moving the landing gear forward, and since KSP doesn't have multi-position landing gear, my solution was to add some separatrons to the nose :P
L897[14:50:39] <ve2dmn> right now the current acent logic I have is :minmum between
L898[14:50:40] <ve2dmn> SpeedPitch TO (100-(GROUNDSPEED/12)).
L899[14:50:40] <ve2dmn> LOCK AltitudePitch TO (90 - ((SHIP:Altitude /60000 )*90)).
L900[14:51:02] <ve2dmn> that gives you a value between 0 and 90 degree
L901[14:51:03] <Mathuin> I haven't bothered adjusting pitch with the gravity turn after the initial nudge.
L902[14:51:28] <madmerlyn> my vertical rocket script just does 0.2 pitch adjustments every 0.2s
L903[14:51:33] <madmerlyn> until it reaches a pitch of 1
L904[14:51:51] <Mathuin> I dodged the mid-node staging issue by dropping the launch TWR and it turns out to be more efficient at the end of the day.
L905[14:51:58] <madmerlyn> hardly fine tunes itself for a proper ascent though, I pretty much have to design the rocket around the script
L906[14:52:41] <ve2dmn> I'm trying to design a good-enough universal script
L907[14:52:50] <madmerlyn> my spaceplane script is a lot more versatile though, it's worked on every plane I've loaded it on
L908[14:53:17] <madmerlyn> course I don't have many spaceplanes that are really low TWR so that probably helps
L909[14:53:41] <ve2dmn> I'm really bad with spaceplanes, so I don't bother
L910[14:54:37] <madmerlyn> did you look at my planes on kerbalx yesterday?
L911[14:54:47] <ve2dmn> no... maybe I should

L919[14:58:21] <madmerlyn> all the planes labeled Gallahad have the same wing configuration, just in different payload capacities and cargo configurations
L920[14:58:44] <ve2dmn> before burning up was an issue I had to deal with... I wind up taking this screenshot: https://steamuserimages-a.akamaihd.net/ugc/525002725032009296/0D403A502980E5B2CF690E7BBA56A5869211A4B1/
L921[14:58:59] <madmerlyn> Gallahad-L and LC are the "Lite" versions that are only rated around 20t cargo and have a slightly shorter cargo bay, the standard Gallahad can do 55t of cargo with a longer bay
L922[14:59:23] <madmerlyn> that a re-entry shot?
L923[14:59:43] <madmerlyn> for re-entry I use a descent profile in trajectories of 47/42/37
L924[14:59:55] <madmerlyn> basically I stay close to 40-45 degrees until I go completely subsonic
L925[15:00:01] <madmerlyn> then I push my nose down and drop altitude
L926[15:00:31] <ve2dmn> I also have one of a burning cross, because my Eve sat was designed as an X of sats on top a long line of fuel tanks...
L927[15:00:37] <madmerlyn> trying to hold 45 degree pitch will give you a good indication if you need to balance your fuel a bit too
L928[15:00:39] <ve2dmn> not a volontary image
L929[15:01:00] <madmerlyn> if your nose keeps pulling down pump full back, if it keeps pushing up pump fuel forward
L930[15:01:17] <madmerlyn> once you have good control authority for keeping your nose around 45 degrees you're balanced enough to land
L931[15:01:29] <ve2dmn> madmerlyn: I'm not even that design would work these days
L932[15:02:02] <ve2dmn> I'll try you designs later... I have a 45min burn to push an asteroid first
L933[15:02:55] <bees> ve2dmn: launch factorio while you are burning in ksp
L934[15:03:09] <bees> whatcouldpossiblygowrong
L935[15:03:12] <ve2dmn> I don't have factorio... yet
L936[15:03:30] <Mathuin> I was playing KSP and CivV because the wife takes too long with her turns.
L937[15:03:41] <madmerlyn> ve2dmn when I started redeveloping on the Gallahad class I was using SpaceY nosecones, but I made pure stock variants for KerbalX
L938[15:04:07] <ve2dmn> Mathuin: you have a wife that plays Civ5 ? lucky you. None of my friends do :/
L939[15:04:13] <madmerlyn> then I discovered that in spite of the 2.5m nosecone having low skin temperature and low mass, it performed very well in the normal 100% heating or whatever default is
L940[15:04:36] <Mathuin> ve2dmn: my wife plays just about as well as me -- I'm superior in combat, she's more of a diplomat -- and she really likes playing.
L941[15:04:39] <madmerlyn> so now I primarily just use my stock versions
L942[15:04:52] <ve2dmn> my best bug yet: https://steamuserimages-a.akamaihd.net/ugc/52122954224630178/5F9D49DACE3D4BFEEFAC7F2AEAAACB1872BC698A/
L943[15:05:04] <madmerlyn> they both have similar dv on orbit and everything so I don't really gain much by using the SpaceY nose except a color scheme that clashes with the rest of the ship
L944[15:05:35] <madmerlyn> only 1 KAC? I wish I could keep my space program that focused. lol
L945[15:05:47] <madmerlyn> I'm down to 3 alarms and i'm like.. wtf why don't I have more in progress
L946[15:05:59] <ve2dmn> that's the compact view
L947[15:06:26] <Mathuin> It's raining Kerbals.
L948[15:06:37] <madmerlyn> I've been stalled out last couple playsessions trying to figure out how I want to do my Spartan VI mission to Eeloo
L949[15:07:08] <madmerlyn> first one was going to use NFP Hall-Effect thrusters, but then I realized the burns would be like 20m long
L950[15:07:36] <ve2dmn> madmerlyn: my usual spaceplane landings: https://steamuserimages-a.akamaihd.net/ugc/526129167440612178/FB43F6288E2FE9D079A2359C2D59E6B02D78091B/
L951[15:07:52] <madmerlyn> then I switched to a monoP OM engine from NFP, but it was too wide to fit in my plane so I had to develop a proper lifter for it
L952[15:08:16] <madmerlyn> ve2dmn you just gotta approach correctly
L953[15:08:37] <madmerlyn> when I started aiming my initial trajectory at the mountains instead of the KSC landing became so much easier
L954[15:08:42] <ve2dmn> Mathuin: on that screenshot, everytime I would eject the kerbal, it would simply create a new zombie one...
L955[15:08:52] <madmerlyn> I aim my deorbit burn so trajectories puts its X on the mountains
L956[15:09:04] <madmerlyn> do my 37-47 degree pitch until I'm subsonic
L957[15:09:19] <madmerlyn> which usually puts me right above the mountains at around 17-20km altitude
L958[15:09:50] <madmerlyn> then I push my nose down and descend, usually doing 40 degrees below horizon until I get under 10km then bringing it up to eventually 10 degrees below horizon until I get down to 2km
L959[15:10:10] <madmerlyn> and then just gradually level out until I'm approaching the runway below 200m
L960[15:10:11] <Mathuin> Is there an interrupt key for kOS? Stop what's running and bring me back to a prompt?
L961[15:10:18] <ve2dmn> I brb, I'll need to do a quick run to a friend's house to pick up her mail while she's on vacation.... and I need to shower first

L980[15:15:59] <madmerlyn> another thing looking at the launch scripts, consider parameters for your target altitude, that way you can just call your script like `run launch1(150000).` if you want to change your target altitude without editing the script
L981[15:16:54] <madmerlyn> top of script just put `parameter orbitHeight is 100000` that way it defaults to 100km if you don't specify the parameter, but you have the option to put a different number in there if you want to
L982[15:17:09] <Mathuin> Oooh, that launch was tuned well enough that when I finished insertion my Pe was 27k!

L984[15:19:02] <Mathuin> In retrospect, storing a JSON file of settings for ships isn't as good as storing the information on the ships themselves.
L985[15:19:36] <madmerlyn> lol serialization for serialization's sake is not always good no :P
L986[15:20:01] <Mathuin> It's not for serialization's sake, it's a way of storing parameters so I don't have to modify the script, much as you said.
L987[15:20:04] <madmerlyn> really only reason to serialize in something like kOS is if you're trying to do some machine learning or something
L988[15:20:07] <Mathuin> If I could store them _in_ the rocket...
L989[15:21:02] <madmerlyn> just identify things you might want to change on different types of launch scenarios and convert them into variables that are passed through parameters
L990[15:21:34] <madmerlyn> it'd be nice if kOS had a way of building terminal menus, but parameters work well enough in absence of that
L991[15:22:06] <Mathuin> madmerlyn: that's part of why I want kOS Prop Monitor to work.
L992[15:22:12] <madmerlyn> I thought it'd be cool to have a bootloader with a menu to let you select an option that determines which scripts get copied to your kOS computer and executed

L1025[15:45:21] <madmerlyn> the Gallahad-L flies really well too, but you gotta get used to it because it's a lot bigger and an off-balanced approach won't end well
L1026[15:45:39] <madmerlyn> but I'm not even sure what the stall speed is, it's somewhere between 50 and 70m/s
L1027[15:45:59] <madmerlyn> and after you balance the nose on initial re-entry it's got plenty of control

L1038[15:58:08] <Mathuin> Right now I gravity turn until 40k at which point I chase Ap maintaining a 60 second distance.
L1039[15:58:21] <Mathuin> But when I reach 40k, I'm at 110 seconds to Ap.
L1040[15:58:31] <Mathuin> Why not start chasing Ap once I'm 60 seconds from it?
L1041[15:59:40] <madmerlyn> now that I think about it I could design a Falcon Heavy booster that behaves the way they want the real one too

L1044[16:02:06] <madmerlyn> yeah I need to work on tuning an efficient ascent though
L1045[16:02:17] <madmerlyn> my vertical rocket script is nowhere near as good as my plane one

L1055[16:05:03] <ve2dmn> madmerlyn: I also have https://github.com/ve2dmn/AsteroidScanner but it's broken
L1056[16:05:42] <madmerlyn> I saw that, I've not forayed into actual mod development though as most tutorials I've found for KSP mods involve Visual Studio and I use Linux at home
L1057[16:06:03] <JCB> I would love to do some parts and mods stuff myself..
L1058[16:06:24] <ve2dmn> Mathuin: which reminds me: I should split my scripts according to gravity turn alogrithms and just call the needed functions

L1063[16:07:01] <ve2dmn> madmerlyn: the basic idea: it scans the map for astroids crossing Kerbin and add a KAC alarm
L1064[16:07:31] <ve2dmn> And by crossing I mean <70km
L1065[16:08:16] <madmerlyn> how do you handle circularization? my script points at -1 pitch and switches between -1 and +6 to maintain apo until it's finished
L1066[16:08:42] <ve2dmn> I was trying to add a relevant contract available... either by spawning an asteroid with the relevant orbit or give a premade-contract that give you the next found asteroid as an objective
L1067[16:08:50] <ve2dmn> both idea failed miserably
L1068[16:09:44] <madmerlyn> my KerbalX planes, I haven't tested or updated the Crow for 1.3.1, I like the Hodor better in every metric so I don't use Crow at all anymore

L1070[16:10:00] <madmerlyn> I use Lancelot for crew transfers, Hodor for light cargo
L1071[16:10:14] <madmerlyn> yeah my mk2 cargo drone is called the Hodor Mk1
L1072[16:10:17] <JCB> ... I should maybe see about doing something with my Dynafly...
L1073[16:10:35] <madmerlyn> the original design did happen around a certain door-holding event haha
L1074[16:10:42] <ve2dmn> "Hold door for launch windows"
L1075[16:11:07] <madmerlyn> Hodor has been tested with about 8t of payload to LKO successfully
L1076[16:11:10] <JCB> With my Mule cargo plane.. half tempted to setup an arctic base.. if I can figure out hwo to get stuff to fit the cargo bay and still wheel out on its own without blowing up
L1077[16:11:13] <madmerlyn> it's great for refueling small craft
L1078[16:11:41] <madmerlyn> Gallahad-L does most of the cargo work in my career though
L1079[16:11:58] <madmerlyn> can do at least 18t to orbit and carry 2.5m parts comfortably
L1080[16:12:07] <madmerlyn> and the full sized Gallahad can do 55t
L1081[16:12:34] <madmerlyn> I don't have a lot of launches in that weight class that also fit in a mk3 cargobay though, which is why I developed the L heh

L1094[16:16:15] <ve2dmn> as if you made the Ki too small, if I remember my PID correctly
L1095[16:17:41] <madmerlyn> this is Gallahad-L https://i.imgur.com/xr6ZqDL.png I have since changed the canards a little, clipped them in so they look less awkward
L1096[16:18:14] <ve2dmn> I see you got your ducks in a row there...
L1097[16:18:30] <madmerlyn> and the full sized Gallahad https://i.imgur.com/zUXKYMo.png same story, I've since clipped the canards in for better aesthetics
L1098[16:18:41] <madmerlyn> the canards are still visible, just don't protrude as much

L1100[16:19:19] <madmerlyn> and this is the hodor deploying a 700kg probe, which is way below its rated cargo capacity https://i.imgur.com/rm6OLkZ.png
L1101[16:19:30] <JCB> eh.. guess I always thought too thick to be a proper wing..
L1102[16:19:57] <ve2dmn> JCB: it's thinking outside the box.
L1103[16:20:07] <madmerlyn> well the problem with mk3 planes is they tend to have very heavy noses and be long, so you need good control surfaces in the front
L1104[16:20:21] <madmerlyn> I couldn't make a canard that looked better with other stock wings
L1105[16:20:32] <madmerlyn> not that had enough lift to get that monster off the ground anyway
L1106[16:21:07] <madmerlyn> 55t on the full size, can probably do more that's just the biggest payload I've taken
L1107[16:21:23] <madmerlyn> AND it does 55t to orbit with at least 600dv left for maneuvering + deorbit burn
L1108[16:21:43] <madmerlyn> and it flies well enough you can glide it back to runway without powering up the engines if you approach correctly
L1109[16:22:19] <madmerlyn> I've taken a 40t payload to HKO and brought a Gallahad back to the runway
L1110[16:22:44] <madmerlyn> that was before I mastered my landing approach though, that one had some minor runway damage on landing ;)
L1111[16:22:56] <madmerlyn> only lost a few rapiers and a small wing section though
L1112[16:22:57] <ve2dmn> madmerlyn: I could use your approach to do space tourism on the cheap
L1113[16:23:21] <madmerlyn> that was the flight that made me think up using "landing assist gears" on the tail to prevent tailstrikes
L1114[16:23:32] <umaxtu> didn't Concorde do that?
L1115[16:24:04] <madmerlyn> maybe? I know most commercial liners have multiposition gear to accommodate needing to pivot on takeoff and preventing tailstrikes on landing
L1116[16:24:05] <JCB> ya.. it had a pair of little 'roller skate' type wheels near the tail
L1117[16:24:44] <JCB> a number of commerial airlines have tail strike skids... might be the odd one out of russia that has a retractable wheel skid
L1118[16:26:05] <umaxtu> it sure was a pretty plane
L1119[16:26:40] <ve2dmn> umaxtu: sadly, not commercially viable
L1120[16:27:23] <umaxtu> what do you think Boom's chances are?
L1121[16:27:34] <JCB> at least not in that form.. though the design was from a long time ago
L1122[16:27:57] <Mathuin> Whoa, the 60s Ap occurs at 14k much earlier than I expected.
L1123[16:28:20] <JCB> heck.. the 747 already left all NA airline carriers... only on international ones
L1124[16:29:08] <madmerlyn> putting 1 extra set of deployable gear on AG5 for my big planes worked wonders though

L1135[16:41:48] <JCB> Lol... have a rocket called the '12 pack'... flies 12 passengers and a pilot.
L1136[16:42:56] <JCB> would love to find a large flat area on the mun.. set up some sort of a base.. be nice to have a place to aim for when the mood hits
L1137[16:43:43] <ve2dmn> madmerlyn: do you have a model that could fly 12 kerbals in orbit and back down for cheap?
L1138[16:44:01] <madmerlyn> I do but it's still in experimental testing
L1139[16:44:26] <madmerlyn> and it doesn't fly 12, it flies more like 38
L1140[16:44:32] <ve2dmn> JCB: I usually aim for the <insert spoiler place here>. it's flat enough and easy enough to aim for
L1141[16:44:43] <madmerlyn> basically replaced the cargohold on the L with 2 of the 16 seat crew cabins
L1142[16:45:06] <madmerlyn> just needs some tweaking to accommodate for the different dry mass distribution
L1143[16:45:09] <ve2dmn> madmerlyn: get Tourism Plus and you'll be rolling in $ in no time
L1144[16:45:56] <madmerlyn> another option ve2dmn
L1145[16:46:30] <madmerlyn> can build a 2.5m based stack, though getting 12 kerbals would require 3 hitchhikers, with its own fuel supply and engine in the full size gallahad
L1146[16:46:53] <madmerlyn> gallahad puts it in orbit, opens cargobay and then it goes off on its own
L1147[16:47:20] <madmerlyn> and in theory you could use that scheme to go to say.. minmus, come back to the gallahad get back in cargobay for a safe landing
L1148[16:47:22] <JCB> while I can land no problem, no shadows needed.. I seem to have troubles getting to places that are somewhat flat. A lot of my landings end up on a slow, sometimes pretty steap
L1149[16:48:02] <JCB> my 12 pack used a set of 6 mk1 crew cabins.. 3 radial in two layers
L1150[16:48:17] <madmerlyn> course if you want to make a really ugly tourism vessel that fits inside the gallahad
L1151[16:48:22] <JCB> centered it around a 'spine' structure..
L1152[16:48:29] <madmerlyn> use the mk1 crew cabins with quadcouplers
L1153[16:48:55] <madmerlyn> could have seats for 16 and still fit in mk3 cargobay
L1154[16:49:04] <ve2dmn> my design are from early in the tech tree
L1155[16:49:05] <madmerlyn> probably be lighter than 3 hitchhikers too
L1156[16:49:21] <ve2dmn> but they work, so I kept them
L1157[16:49:36] <madmerlyn> I haven't gotten a lot of tourism contracts this playthrough
L1158[16:49:48] <madmerlyn> I think the game looks at the contracts you decline and then assigns priority based on that
L1159[16:50:14] <ve2dmn> my funding comes from tourism contracts beause I can automate them
L1160[16:50:17] <madmerlyn> I've gotten a LOT of rescue contracts, a moderate amount of satellite contracts, and a lot of DMagic contracts, not a lot of tourism

L1163[16:50:53] <madmerlyn> 1 2.5m cargo container can net me 1M funds
L1164[16:51:13] <JCB> I ended up building a 'cruise ship' for 10... left it in orbit for later use
L1165[16:51:31] <JCB> brought everyone down on rockets after
L1166[16:52:01] <Mathuin> Rescue contracts are the best, because those jerks become employees.
L1167[16:52:11] <madmerlyn> I think I might go destroy some of my earlier vessels, like I created a fuel tug for delivering fuel from the mun, but it's a bad design and old, I think I need to just blow it up and start fresh

L1219[17:19:39] <Iskierka> steel is about 8 kg/l, IIRC iron ore is around 4 kg/l, so 6 kg/l isn't nonsense

L1224[17:21:09] <UmbralRaptor> wait, really can't math. iron is 7200 (IIRC) kg/m³, or 7.2 tonnes/m³
L1225[17:21:43] <Iskierka> solids are extremely dense, the only dense parts of a rocket tend to be liquids
L1226[17:21:50] <Iskierka> so it's not unreasonable
L1227[17:21:54] <ve2dmn> UmbralRaptor: check the screenshot... I believe aside from the look of the astroid, the rest is ok-ish
L1228[17:22:07] <Iskierka> the question is if the asteroid would be fluffy at that size

L1232[17:24:00] <ve2dmn> btw, the issue I have with USI ART is that the asteroids are generally big when I first encouter and dock...
L1233[17:24:23] <ve2dmn> then I reload and the astroids are back to looking stock, but with the stats of ART

L1279[18:36:26] <Mathuin> I was heavily inspired by the post I cite at the top of the gravity turn script, and by the GravityTurn mod.
L1280[18:36:36] <ve2dmn> You have losses due to drag, and loses due to gravity
L1281[18:36:59] <ve2dmn> if it was airless, I would simply make sure AP was mere seconds in front
L1282[18:37:12] <ve2dmn> (and be as horinzontal as possible)
L1283[18:37:20] <Mathuin> Yeah, that's horrible, I tried that.
L1284[18:37:35] <Mathuin> Setting the intermediate altitude to like 14k where AP is 60s out for the first time.
L1285[18:37:48] <ve2dmn> But Kerbin has an atmosphere, so you have to account for that
L1286[18:38:22] <ve2dmn> so which makes you loses more dV? I tried to find a tradeoff
L1287[18:38:30] <ve2dmn> The code didn't work
L1288[18:38:43] <Mathuin> Did you use PID loops or something else?
L1289[18:38:54] <ve2dmn> no PID.

L1292[18:39:43] <Mathuin> That sounds heavy duty
L1293[18:40:25] <ve2dmn> well... I was able to make it into orbit by follwing a simple logic of "at X speed, pitch Y angle"
L1294[18:40:32] <ve2dmn> I was trying to optimise it
L1295[18:40:51] <ve2dmn> That rabbid hole was too much for my small brain
L1296[18:41:22] <ve2dmn> So the code has been sitting there for months and you've convinced me to take another look yesterday
L1297[18:42:04] <Mathuin> Ah, I was enticed by the grace of letting gravity pull me into the turn.
L1298[18:50:47] <ve2dmn> How else would you minimise dV?
L1299[18:51:33] <Mathuin> Using just enough thrust to get me up and pointed in the right direction (tweaking TWR in my code) and choosing the right angle/speed combination were what I was doing.
L1300[18:52:03] <ve2dmn> How would you be sure that is the absolute minimum amount of dV?

L1384[21:11:42] <ve2dmn> no. Crash on recovering craft
L1385[21:11:59] <ve2dmn> autosave was on landing in the ocean
L1386[21:12:43] <darsie> I mean, does KSP autosave on crash?

L1403[21:33:40] <ve2dmn> Stripper or packer...
L1404[21:34:19] <ve2dmn> the point is to strip the useless bits and pack the same fucntions into a smaller package
L1405[21:35:02] <ve2dmn> it's obvious... there's probably a lot that could be done to improve it, like smaller function names, etc

L1408[21:46:11] <madmerlyn> and.. that made it better, lol
L1409[21:50:48] <ve2dmn> they are stabilizer, but they bring the COL in front
L1410[21:52:38] <umaxtu> maybe a reality vs ksp thing?
L1411[21:53:00] <madmerlyn> well yeah in reality canards create turbulence on the wings behind them etc.
L1412[21:53:21] <madmerlyn> in KSP they don't so that's why they work *so* well, according to this guy :P
L1413[21:53:45] <madmerlyn> but my no canard version is actually better so now I'm probably going to have to redesign every plane in the Gallahad family, lol

L1425[22:22:08] <ve2dmn> madmerlyn: your Lancelot Mk1 looks a lot like my old spaceplanes
L1426[22:22:22] <madmerlyn> it's one of my old ones :D
L1427[22:22:35] <ve2dmn> Except I used a mix of engines
L1428[22:22:38] <madmerlyn> way too much engine power too hehe
L1429[22:22:44] <madmerlyn> like it could probably work with 2 engines
L1430[22:25:05] <madmerlyn> so my new revisions with the 36 kerbal capacity LC-XL Gallahad
L1431[22:25:27] <madmerlyn> if you refuel it on orbit with just a little bit of fuel
L1432[22:25:32] <madmerlyn> could go to Mun or Minmus orbit
L1433[22:25:35] <madmerlyn> and back
L1434[22:25:53] <madmerlyn> could probably even land on minmus if you're particularly adventurous
L1435[22:26:57] <ve2dmn> yeah, looking at your designs and script, it's clear that I made spaceplanes with not enough engine power
L1436[22:27:30] <ve2dmn> was trying to save dV but I wind up not being able to make it into orbit
L1437[22:27:58] <madmerlyn> I hate SSTOs that require complicated ascent profiles :P
L1438[22:28:11] <madmerlyn> if I have to do a 5km nosedive halfway through it's not a good spaceplane IMO
L1439[22:28:47] <ve2dmn> It just confirmed my suspicions :/
L1440[22:29:04] <ve2dmn> now I'll just have to learn to land properly
L1441[22:29:31] <madmerlyn> since their purpose is to recover all the non-fuel costs, I don't fret too much if having a little more engine power means burning more fuel, because I'm still getting cost per ton of payload below 1k
L1442[22:29:47] <ve2dmn> basically I try to aim too high and overdesign... which usually means lacking something somewhere

L1482[22:59:07] <Oneiros> i think we're at around 0.22AUD now and its always going up fast
L1483[22:59:54] <Oneiros> plus daily supply fees which pretty much double the costs for a one person flat
L1484[23:00:13] <ve2dmn> supply fees?
L1485[23:01:26] <Oneiros> something like 90c a day just to have electricity supplied from the grid
L1486[23:02:09] <Oneiros> makes me want to work towards a complete solar setup the way prices are going here
L1487[23:03:50] * UmbralRaptor is currently paying more connection fees than anything else. I think it worked out to 0.67 USD/kWh last month.
L1488[23:04:40] <Oneiros> yikes
L1489[23:05:36] <ve2dmn> I'll have to check. I don't think I have theses fees
L1490[23:07:54] <ve2dmn> ha. I do pay that. it's 25CAD per month
L1491[23:08:31] <Oneiros> yeh
L1492[23:09:14] <ve2dmn> last year 1860 kWh x 0.0571 $ + 471 kWh x 0.0868 $
L1493[23:09:38] <ve2dmn> (for 2 months)
L1494[23:10:05] <ve2dmn> and that 25CAD was for 60 days, not for a month
L1495[23:10:41] <Oneiros> so cheap
