Thanks! Glad you like it I posted a while back with an overview of the 'flight computer', and a code snippet for how I worked out which celestial body the craft is orbiting; I've finialised that code, and it's a lot more foolproof http://forum.kerbalspaceprogram.com/threads/66393-Hardware-Plugin-Arduino-based-physical-display-serial-port-io-tutorial-%2808-Oct%29?p=1381446#post1381446 And by all means, borrow away!

Thanks! I wanted something that almost looked professional, but still had that Kerbal humour I'm still working on the flight data readout panel, at the moment it's a bunch of LCD / LED readouts and a bunch of wires all over the desk

So... I made a thing. Again, thankyou zitronen for this wonderful plugin! <3 Also, the insides... they're a bit... Kerbal

Hey everyone In case other people are also wanting to work with the current SOI, I have worked out a way to calculate it. It's a bit... , but it works #define NoSOI -1 #define KerbolSOI 0 #define KerbinSOI 1 #define MunSOI 2 #define MinmusSOI 3 #define MohoSOI 4 #define EveSOI 5 #define DunaSOI 6 #define IkeSOI 7 #define JoolSOI 8 #define LaytheSOI 9 #define VallSOI 10 #define BopSOI 11 #define TyloSOI 12 #define GillySOI 13 #define PolSOI 14 #define DresSOI 15 #define EElooSOI 16 //same codes as in a savefile double Oldecc=-1;//keep value of orbital eccentricity for comparison next loop int currentSOI=-1; void UpdateDisplayOnNewPacket() { if (Oldecc==-1 || currentSOI==-1) currentSOI=resolveSOI();//force refresh if SOI unknown. else if (Oldecc<=1 && VData.e>1) currentSOI=resolveSOI();//force refresh of SOI if orbit jumps to hyperbolic (e.g. entering a smaller SOI) else if (Oldecc>=1 && VData.e<1) currentSOI=resolveSOI();//e.g. jumping to solar from planetary else if ( (VData.e>(Oldecc*1.05) ) || (VData.e<(Oldecc*0.95) ) ) currentSOI=resolveSOI(); //force refresh if the eccentricity 'jumps'; indicates an SOI change without a hyperbolic orbit (e.g. Laythe horseshoe orbit) //'resolveSOI' could be run every loop, but conditional states used to save some processor time. //add more display update code here ...

Updated: Can now calculate SOI regardless of whether elliptical, parabolic, or hyperbolic aka escape trajectory. Also, I promised pics once I got them uploaded - I know photobucket's not the best, but it works So, once again, thankyou zitronen, for this wonderful plugin!

Can't be stolen - it's borrowed... It's not plagiarism if it's properly referenced! Thankyou so much for the update, I'm gonna have a loooooooooooootta fun with this!

Hi there! First, I want to thank you for this amazing plugin - I've been wanting to build a flight computer for a while! So thankyou for making that idea a reality! I was wondering how it might be possible to add more flight data into the plugin itself? I'm reasonably proficient with Arduinos, but know nothing of the PC side. I was thinking things like Horizontal land speed, What the current SOI is, and possibly the (many, many) variables that make up the navball? I am asking because I am hoping to make a complete cockpit without relying on any HUD on screen... I will post pics of my panel based on this plugin as well, once I can get them hosted, though at the moment half of it is breadboard and wires Thanks again! -Amelia Eatyaheart

This is an amazing project, been loving watching it develop I have to ask though - how are you getting your yaw/pitch/roll values out of KSP? I'd love to make something like this (if I can) - I'm good with arduinos, but no clue on how to connect to the computer for the data!
