Elderberry Ni is "just" a real-time GUI for crxTelemetry, so one would already be using it. Any graphics suite/Python script/whathaveyou that can continually read in CSV data and update the display could be used; I'm using gnuplot for post-flight data readouts, but it might be possible to tweak that into an almost real-time display... crxTelemetry is compatible with 0.17, at least I haven't found any glitches yet apart from the crew readouts (just don't use them ) And yes, I guess, "Raspberry Pi(e)" already contains a dose of Monty Python

[0.17] Electrical Energy Plugin | v1.5 (Oct 12)
Corax replied to Kreuzung's topic in KSP1 Mod Releases
I'm not trying to criticise your design decisions, and also I'm no expert on solar cells, but you might want to consider the 5-20% figures are probably true for consumer grade solar panels (the whole assembly including converter etc.) with 5% in cheap stuff like toys or solar garden lights, and 20+% in "serious" consumer panels, aka. photovoltaic power supply. Modern high end solar cells (as might be found in cutting-edge space systems) can have up to twice that efficiency. Also something to keep in mind is that the quoted solar cell efficiency rating is measured through quite a thick layer of atmosphere. Anyway, thanks for your excellent plugin! -
KSP in full-screen windowed mode! quick 'n simple (windows only)
Corax replied to Moach's topic in KSP1 Tutorials
Not sure what other OSes you are talking about, as the only other OS that is officially supported is MacOS, and as for unsupported OSes (aka. Linux ), this method works just as well, as I have repeatedly tested and stated in several threads asking about exactly this. In short, the bad news: It probably doesn't work for Mac users. The good news though is for Linux users: just launch $ wine KSP.exe -popupwindow, or create a shortcut in the manner Moach described. -
Windowed Full-screen option
Corax replied to Tim_Barrett's topic in KSP1 Suggestions & Development Discussion
Harvester posted about this Unity feature some time ago: Assuming you are using Windows, copy your KSP shortcut (just to be safe), then right-click and change the properties to something like "X:\Path\to\KSP.exe -popupwindow" (where X: etc. are the values already in there). I'm not on Windows, so edit at your own discretion. In the Graphics section of the KSP settings, change the resolution to your desktop's resolution, uncheck "Fullscreen", and you should be good to go. I can confirm it working with Linux/Wine, no idea about MacOS though. -

I give you that. But then, I should have written mdot as á¹ I refuse to bow to the stupidification through modern technology. If my calculator doesn't know how to interpret a formula in mathematical notation, it's so much more important that I do, and feed it to the calculator in the little bytes it can manage. I didn't mean to provide a how-to-program-your-calculator. Regardless, commutativity says it doesn't matter whether you divide first and then multiply, or the other way around. 2*(10/4) = (2/4)*10 = (2*10)/4 = 5

It depends on your throttle setting; the less throttle, the longer the burn. Keep in mind that fuel consumption calculations are "bugged" as of 0.16, i.e. the engines use disproportionately less fuel on lower throttle settings. Therefore I will assume full throttle setting throughout this experiment. From Wikipedia: Fthrust=Isp*mdot*g Fthrust [N] Isp mdot [kg/s] (this is what you need to find: the rate at which fuel is burnt) g=9.81 [m/s2], Earth's (or Kerbin's) standard acceleration mdot=Fthrust/Isp*g Now that you have mdot, you divide your fuel mass (depending on your fuel tank(s)) by mdot to get the burn duration in seconds. For example, the LV-T30 ("liquidEngine1") has max thrust Fthrust=215 (kN) vacuum specific impulse Isp=370 (s) Plug that into the formula above, and you get mdot=Fthrust/Isp*g =215kN/370s*9.81m/s2 =215000N/3629.7m/s3 =59.23kg/s the FL-T400 ("fuelTank") has a total mass of 2.25t, an empty mass of 0.25t, and a fuel capacity of 400 units. So the fuel mass is 2.25-0.25=2.0t t=m/mdot =2000kg/59.23kg/s =33.77s If you do the calculation with the Isp at sea level, you get mdot=215kN/320s*9.81m/s2 =215000N/3139.2m/s3 =68.49kg/s and thus t=m/mdot =2000kg/68.49kg/s =29.20s which you can simply test for yourself: Mission elapsed time at engine burn-out: 30s. Close enough, considering ISP varies with atmospheric pressure (i.e. altitude), and the inaccuracy of the mission timer. Oh, and as always, you should really retrace the steps for yourself and verify I didn't accidentally introduce any dimensional or other errors in my equations

You might want to check out The Mars Project, a science vision by Wernher von Braun himself. It is of course a bit dated, having been first published in the late 1940s, but it's more science than fiction, well except the Martians, whose existence was still widely considered likely at the time. Oh and btw. "von Braun" is pronounced as "fon Brown", not as "one Brawn". Just for you NASA types out there (and whoever else didn't know)... Sorry for OT Which I guess is why we (humans) are flying a space station now and have been doing so almost continuously for the last what... thirty? fourty? years? It's much more budget issues that keep humanity from expanding beyond LEO than too advanced technology.

[PLUGIN, PART, 0.15+] crxTelemetryMk2 Module alpha
Corax replied to Corax's topic in KSP1 Mod Releases
You have to set your brother's IP address in your telemetry plugin's part.cfg Also he has to make sure his firewall allows incoming traffic from your IP address, and probably point his Elderberry Ni to your IP address as well. -
Granted I may have read more into the OP than what was actually intended. It is of course fine for anyone to create another mod repository with whatever backend they opt to use. There are already quite a few external repositories. In that respect, yet another repository can only increase the possible choices for users and authors alike, which I think is generally a good thing; time will tell which one will emerge as "the" repository favoured by people looking for mods. I'd say go for it, create that site, anounce it once it's done, and see if it is being accepted.

Being forced into something as the only way to do things is always a bad idea. Several developers are already using github, some aren't, and likely some won't ever - to be honest, I'm still struggling with getting github working from within MonoDevelop, as long as I can't get that worked out, I'm not willing to go to the extra length of manually maintaining a git repository.

My experience as well. Also if a reputation system were to be meaningful, it would be necessary to be able to give negative reputation as well. Either way, I don't think a reputation system can work at all outside a relatively small, relatively close community.

Kerbal Space Program Trajectory Optimization Tool
Corax replied to Arrowstar's topic in KSP1 Mod Development
It's a common misconception that the telemetry plugin does any graphing. Its only job is to send data across the network. I guess what you have in mind is "Elderberry Ni", an addon to the plugin that takes the data and pretty-prints it, so to speak. You can basically do the same stuff with gnuplot, or Excel, or any other graphing software, Elderberry is just a user-friendly interface to the data that does the "heavy" lifting. Which (kind of) answers the following question: None, it is a C# plugin to KSP that uses functions exposed by Unity and KSP. From what I've seen, Warringer uses AWT for his graphs. -
May I suggest having this as a global profile option? It's really tedious to turn it off for every single post, or forget and have to edit.

[0.17] ExPI: Space Stations [0.4], Interplanetary Probes [0.1.2]
Corax replied to Pelf's topic in KSP1 Mod Releases
While I understand "spoilering" images in official threads to a certain degree, why should they care in someone's personal thread? EDIT: Especially if the thread's purpose is showcasing part models... Also, the thread doesn't load any faster if you "hide" images inside spoiler tags, the images are loaded all the same. -
[Question] How do i turn off the Day/Night Cycle?

Kerbin isnt quite a physical object in that manner, its actually on rails. My sil, that is impossibru.Which is about exactly what he said. -
[PLUGIN, PART, 0.15+] crxTelemetryMk2 Module alpha
Corax replied to Corax's topic in KSP1 Mod Releases
Good call, looks promising. Now only to find out how to get a reference to this... -
What's the rationale behind not including a link to what you are describing into the post where you talk about it? Maybe it's just me, but I have signatures disabled because of too much <strike>stupid</strike> useless stuff in too many of them...

[PLUGIN, PART, 0.15+] crxTelemetryMk2 Module alpha
Corax replied to Corax's topic in KSP1 Mod Releases
What lukasni said. To transmit telemetry over the internet, you have to know your friend's IPv4 Address (something like "123.45.67.89"), or he has to have a DNS entry pointed to his machine (something like "mymachine.mydomain.net"). There are services for dial-up internet that change the DNS entry whenever you get a new address assigned on dial-up, some are free of charge. Once you know that, your friend has to open a port to his machine on his router and/or firewall and start a receiver program [e.g. netcat or UDPreceiver (or Elderberry Ni, see below)], you have to edit your part.cfg and/or persistent.sfs to point to his address, and you're all set. EDIT: Note that I am not familiar with Elderberry Ni, but you should be able to do the same with that program; in addition to the steps mentioned above, basically you would have to download the Elderberry package on both computers (just to make sure one has the rocket part, and the other one has the visualization program). The sender has to edit the Elderberry's part.cfg to point to the receiver's address instead of localhost or 127.0.0.1, while the receiver fires up the Elderberry program. -
Of course you are able to do maths without ever having seen a rocket. The point is verifying the theoretical results with an actual flight test...

Problem- crew swap during orbital EVA?

Kerbal Space Program Manager proud to announce the Kerbals\' first Mun landing! In a surprise announcement, Kerbal Space Program Manager Billy-Bobly Kerman revealed the first succesful landing on Kerbin\'s satellite, the Mun. Despite serious setbacks, resulting budget cuts, and a following total news blackout, the Kerbal Space Center say they managed to get a crew of three, and even a roving vehicle, safely to the surface of the Mun. 'In the name of kerbalkind, we set foot on the good old Mun', was the first transmission received from mission commander Huckleberry F. Kerman. After leaving the landing craft and boarding the rover, the crew of three set out on their surface science mission. 'We\'re having a great time throwing sn..err Mun dust balls at each other... in this... err low... gravity,' was Commander Kerman\'s message to this somewhat puzzled reporter. The Kerbal Space Program regrets that, due to the long range and electrostatic interference from Kerbol, only pre-recorded still images can be made available.
