Freshmeat

Update USI tools to 0.10.1.0. Had the same problem with USI core, solved it for me.

I grew up in the C64 era and has been playing since. KSP has the definite advantage of being a game where I can talk with my wife as I play. Since childhood, I have been deeply fascinated by space, did minor in physics and a masters thesis in history of exobiology. On the subject of shooters, I play these as well for the instant gratification. Sometimes you just crave junk food, other times half the joy is the time spent in the kitchen beforehand.

You, sir, are rather amazing.

Just adding to the heap of praise others have given. The graphic is clean, informative and very fast to consult, everything you could wish for on a chart. I too would love a logarithmic version, but for now, this one goes into my folder of relevant KSP stuff.

I have recently rebuild my Minmus base, all my interplanetary missions get their fuel from there. I have a handy spreadsheet that tells me when to launch for correct initial inclination on the way up, and when to escape Minmus SOI for a given ejection angle from low Kerbin PE.

Still, that is awesome. It also echoes the Rosetta mission and Philae ending up without enough sunlight.

I used a Logitech Dual Shock from around 2010 for quite a while before it got ripped apart and stuffed into a control panel. Worked a lot better than keyboard, but I would not buy one for KSP. Larger joysticks give so much better control.

So, there goes the weekend. Thanks for keeping bugfixing up, the modmakers will surely update eventually. Almost every mod I use is in active development and general bug fixing anyway, and the rest is picked up by @linuxgurugamer for maintenance.

I teach high school physics for a living, and I must say that I love reading a careful examination of a weird phenomena in any set of natural laws. That these laws are different from the ones that drive my car is just an interesting addition. Good work, we ought to have a journal for things like this.

@zitronen Most of the cases you are probably right about the launch manager. However, in the lower layers of the atmosphere at least my rockets needs to be pretty close to prograde, or they will tumble due to drag on the payload. For aircraft, I was able to do altitude hold without overtaxing the Mega, and direction hold would be pretty straightforward to do.

@ljkjl Launch autopilot will be quite difficult to do in KSPSerialIO. The data packet does not contain the angles for prograde direction, and without that you cannot check that your rocket goes in the right direction. You could go pitch vs arctan(VVI/V_surf), but for trigonometry the Mega is severely lacking in computing speed. Good news is that the Mega is easily replaceable with a Due and some logic level shifters if you already have a Mega and want to delay the decision.

Cool start, what are the plans.

Hi Adjen, my zero order guess would be that the display is quite resource intensive, so the Mega does not have the computing power to manage the information stream from KSP at the same time. I ran into the issue when I tried to do trigonometric formulae and square roots in each loop. Once the buffer overruns, the Mega no longer appears connected to KSP, and it disconnects. The smaller displays run very well with the LiquidCrystal_I2C library if they have an I2C backpack. I have two of these connected, however I only update every 200 ms to keep my buffer drained. I do not think that is needed for ordinary display stuff, but I process the numbers somewhat.

Thanks, I thought the mod depended on visual mods to show planets properly. I will try to see if I can make something work.

So, I run a i5-4670@3,4GHz with 8 GB ram and an ATI HD6990 with 2 GB ram. GPP brought it to its knees, which was what I kind of expected. What kind of rig are we looking at if I want to join the fun?

Cool, on reflection I basically wanted to twist your mod to fit my scheme of things; the point for me would be getting a data dump I could parse into my database system. Your vision is different, focused on an ingame log which is quite another thing with different considerations.

This is rather cool. I keep a database myself, but the paperwork is a bother. Are you able to add information about launches and recoveries. Specifically, I would like to know how much science and funds I get, and how much I spend, on a per-vessel basis, and what the crew roster on a launch looks like.

Switch with cover. If you want one with light, be advice that they run 12 V, which means some external power source.

If you don't mind the extra waiting time, Ebay is a lot cheaper for parts. Beware of import taxes though, and if you want to get serious, it will be expensive no matter what, a little at a time. I think I have spend around $150-$200 on stuff related to this project over the last couple of years, starting from absolutely nothing but woodworking tools and basic knowledge of electricity. When I started, I just threw a rotary pot unto an Arduino to get a throttle. Then I sort of just kept going from there. T-bar fader can be done with a slide pot, I recall someone showing it on the forums (probably fan works). I bought an Uno first, but had to change to a Mega, and can warmly recommend it. Also, unless you have a standalone numpad already, I would recommend against gutting a keyboard. The wiring is embedded in some form of plastic sheet, and the num keys are not on a separate circuit. I use a keypad from an old desk telephone, but have begun wiring up a push button based keyboard for better responsiveness. For action groups toggle switches work better. Both @stibbons' and @zitronens plugins are designed with toggle switches in mind. I use cheap ones like these, but these look better. Shop around. Are you sure you need a button for the alarm? A deeply set LED could do if you don't need to push it, and comes at a few cents. You can throw warnings for almost any conditions you can think off, I have low fuel, low charge, low altitude, high velocity (context sensitive) and high temperature. Arduinos talk a dialect of C, but programming can be learned as well.

Windows 7, as I need the full MS office suite installed for work reasons. I use Ubuntu on other machines for the speed and reliability if I don't need Office installed. This post is written from a MacBook, and my primary laptop is a Surface running Windows 10. I don't see the big difference between operating systems these days, all are reliable and easy to use, and I more or less think it has been so since Windows 7. XP ran solid as well, at a time when Linux was a real pain to get running but the only thing that could not be brought down.

I have done some practical work inspired by a similar thread around Christmas or so. The outcome was that refueling at Minmus had substantial savings due to lighter payloads sent to orbit, and the drop to a periapsis did indeed save some dV, the savings where rather small due to steering losses, wrong inclination of Minmus (this could get very bad), and the fact that it is quite a challenge to find the exact escape orbit from Minmus to get the correct argument of periapsis. That being said, figuring out how to calculate ephemerides where quite interesting, and as a bonus I know the launch time for heading to Minmus with the correct inclination. PS: Writing this I just realised that there must be a way to launch from Minmus to get a low inclination on the Kerbin orbit, by tilting the orbit from Minmus. Investigation pending.

Like this?

I would use a single I-beam and two struts going up in a v fashion per leg out. Ordinary parts connects like a tree, which means that you cannot make a connected triangle for stability. Then one or two landing legs mounted at the end. Each leg can hold a surprisingly high load.

I managed to land on Tylo for the first time Note the resources, I had 22 m/s left upon touchdown The craft is a recycled Vall lander. After transferring the crew to their return craft I examined the specs if I repurposed the equipment, life support and ore containers as fuel tanks (and a kind thought to @Angel-125 for making Wild Blue containers reconfigurable on the fly). Then I mounted the lander to the side of a tug as the front docking port was another type: I had to shut down most of the engines, limit the trust of of two of four still usable and distribute all fuel to port side to get a linear thrust, netting an acceleration of whooping 0.55 m/s^2. The image is taken during the 13 minute capture burn at Tylo. The landing operation itself took two tries, thank Kraken for F5/F9. Unfortunately, all science equipment was left at Vall, but I still feel as proud as when I touched down first time on the Mun. And given the ISRU onboard, take-off to orbit was perfectly doable.

I got a mock up to work with Win 7 and a Due, just sending some simple telemetry. Coming from KSPSerialIO, the code structure takes a little change of mindset, but this shows a lot of promise. I consider rebuilding my controller (again), using WS2812 led strips instead of MAX7219 for annuciators and make a matrix keypad that will be used both for the plugin and the Due keyboard library instead of having an old keyboard IC mounted for commands that does not go through the plugin. I will probably do this in stages, and I just agreed taking a few weeks of on a trip with my family, so it can take a while before I get around to bother you with questions and requests.
