00:21 <Bornholio> Now i have more than two

00:22 <Bornholio> oh and a mechjeb case that floats in the deep metalic sea

00:33 <Bornholio> https://i.imgur.com/WHJo3i4.png https://i.imgur.com/DORqbvI.png repeated some moon trips https://i.imgur.com/nktNDUM.png really need totaly boyancy to be a thing balloons need balance otherwise https://i.imgur.com/XZ4wwxS.png had spotty communication when landed https://imgur.com/a/iZCgI

00:34 <soundnfury> yay, gemini

00:38 <Bornholio> for got i posted my glide bombs also https://imgur.com/a/pscgl

00:40 <soundnfury> see also: https://what-if.xkcd.com/138/ https://what-if.xkcd.com/139/

00:47 <Bornholio> those are pre-juno, we now know conclusivly that its not fire truck driving in a circle, and guacaomole layer is now less likely

00:48 <soundnfury> xD

00:48 <soundnfury> btw, https://vignette.wikia.nocookie.net/robotwars/images/6/66/Gemini_arena.jpg/revision/latest?cb=20140309154320 >> https://vignette.wikia.nocookie.net/robotwars/images/1/14/Apollo.png/revision/latest?cb=20160730174104 :P

00:50 <Bornholio> go i need context!

00:51 <soundnfury> Gemini first fought in the Fourth Wars; Apollo in the Eighth Wars (aka first series of the reboot)

00:51 <Bornholio> ah yes robot wars duh

00:52 <soundnfury> :)

00:53 <Bornholio> an empty car wanders the highways until someone notices the credit card charges for gas

00:53 <soundnfury> which is odd, because it's an electric car.

00:54 <Bornholio> it installes a backup generator out of fear when passing through glacier national park almost stalled it

01:38 <awang> Hmmm

01:38 <awang> Anyone tried using a Gamecube controller as a joystick?

01:41 <taniwha> awang: I've used an Elecom controller. It was horrible.

01:42 <awang> First I've heard of Elecom

01:42 <awang> Looks like a [S]NES controller?

01:43 <awang> Doesn't look fun if that's the case

01:43 <taniwha> [s]nes, xbox, sony... they're all the same essentially

01:48 <awang> The controller I was looking at didn't have analog sticks

01:48 <awang> But seems like analog sticks aren't the way to go

01:48 <taniwha> real analog sticks are

01:49 <taniwha> saitek x52: not bad. thrustmaster t.16000m: pretty good

01:49 <taniwha> (haven't tried others recently)

01:50 <awang> Analog sticks for consoles aren't the way to go, then

01:50 <awang> Jeez

01:50 <awang> Those look... complicated

01:50 <taniwha> they are

01:51 <taniwha> though really, a good PC joystick (especially HOTAS) is way more complicated (but better laid out)

01:52 <awang> Wow those are expensive too

01:52 <taniwha> yeah

01:55 <awang> Going to be difficult justifying buying these

01:55 <awang> For the moment at least

01:56 <taniwha> yeah, getting my x52 was rather difficult

01:56 <taniwha> the thrustmaster was easy (though more expensive)

02:11 <wb99999999> hey guys

02:43 <awang> taniwha: What do you do with them besides KSP?

02:43 <awang> wb99999999 \o

02:43 <taniwha> awang: nothing. I got them for KSP

02:57 <awang> That's dedication :P

02:58 <taniwha> sadly, I've barely used the thrustmaster :(

03:00 <Bornholio> https://bato.to/comic/_/comics/isekai-ni-kita-mitai-dakedo-ikanisureba-yoi-no-darou-r22844/ Ive decided to imagine Taniwha is the character from this manga

03:03 <Bornholio> taniwha have you tried the 3d connexion controller with KSP

03:04 <taniwha> not yet. got one, though

03:04 <taniwha> been too busy with other stuff

03:05 <Bornholio> to bad, but good also

03:17 <awang> Why not?

03:18 <awang> *why not use the thrustmaster

03:18 <taniwha> just haven't been playing KSP enough

03:18 <awang> Fair enough

03:28 <taniwha> awang: btw, it's ferram4's fault I bought joysticks for KSP ;)

03:29 <ferram4> ...

03:29 <Qboid> ferram4: ProjectThoth left a message for you in #RO [13.12.2017 05:19:00]: "Yeah, I'm still on the interstage thing... just wondering if you think a monolithic interstage would handle the heat better (with blowout ports or something to partially restore aerodynamics for the flyback cruise)."

03:29 <taniwha> ferram4: we were talking about joysticks, them being expensive and me having bought some just for KSP

03:29 <taniwha> you came in more or less at the end of it and couldn't resist

03:30 <ferram4> Ah.

03:30 <taniwha> however, I really did get a joystick for flying planes in KSP using FAR

03:30 <ferram4> Oh, I was here for a fair bit of it based on my stored backlog.

03:30 <ferram4> Just wasn't paying attention.

03:30 <taniwha> yeah

03:30 <taniwha> just meant the chanserve bit (I have quit/join messages suppressed)

03:31 <ferram4> Had to reboot my PC because the thermal sensors weren't active (for some reason) so the fan wasn't running.

03:31 <awang> That doesn't sound healthy

03:31 <taniwha> yeah, scary

03:32 <UmbralRaptor> Should be fine if you're using liquid sodium cooling.

03:32 <ferram4> More scary: it's a laptop

03:32 <ferram4> That runs hot to begin with

03:33 <ferram4> But all seems to be well now

03:41 <wb99999999> so here's a question of mine

03:43 <wb99999999> how does the benefit of adding side boosters to a stage change, if at all, depending on the Isp of said stage?

03:44 <UmbralRaptor> Example for clarity?

03:45 <Bornholio> https://ocw.mit.edu/courses/aeronautics-and-astronautics/16-50-introduction-to-propulsion-systems-spring-2012/lecture-notes/MIT16_50S12_lec1.pdf

03:46 <Bornholio> see section on optimal stage TWR and max dV

03:46 <wb99999999> I like how Born always have some book/paper/article for me to crunch on XD

03:46 <UmbralRaptor> ^let's go with Bornholio's link

03:47 <Bornholio> that course is a great one for understanding a lot of propuslion

03:48 <Bornholio> take a look at figure 1 for the optimization section and you will see that it is a combination of fuel fraction vs engine mass percent

03:48 <Bornholio> the side boosters push the fuel fraction and twr up at expense of cost and launch total mass

03:49 <Bornholio> but at a certain point they will also bring max dV for a given payload down

03:49 <Bornholio> calculus is mean

03:51 <wb99999999> well this is...surprisingly complicated

03:51 <wb99999999> I should have expected it though, since calculus is almost certainly involved in my original question

03:53 <Bornholio> damn, sorry laymans terms....ISP Good, TWR More gooder sometimes! good night 9's

03:55 <wb99999999> puff what

03:55 <wb99999999> good night then

09:14 <xShadowx> taniwha: his fault i bought one too ;p before FAR i couldnt stand planes, now i even use for rockets heheheh

09:32 <taniwha> rockets take a bit more practice (and more appropriate configuration)
