Aphobius

It's an in-game time challenge.

Challenge is on hold until I think about a better set of rules. Since putting most of the weight on a swing and use it to push a low weight car is far more efficient than what you see in the example video, I'll have to rethink the rules, since that is not what I want the challenge to be about. You can still try it meanwhile, if you want to do something similar to the example video, just don't try to find loopholes in the rules. - You must build a weight powered car that goes as far as possible. Rules: No mods No cheats (debug menu etc.) You are not allowed to use any type of engine You are not allowed to use reaction wheels You are not allowed to use electrically powered wheels The only allowed source of energy is a falling weight The car must weight at most 10t The car must be unmanned Your car must have only one probe core, which must be the first part in front of the car You are allowed to have only one stage, that must at least drop the probe core on the ground The car must be stationary and on the ground when you use the stage The probe core must not be more than 5m away from the car right after you drop it The probe core cannot be touched after it was dropped The car is not allowed to get off the runway No parts can be destroyed at any point Scoring: The score is the distance from the car, after it stopped moving, to the probe core that you dropped on the ground. Leaderboard: Aphobius - 124.8m Example:

Allowing screenshots could be fun, so other people don't copy your procedure, but you should have a video ready to make the time ... official. I don't think a save file is needed, just launch something with a docking port in a 75km circular orbit (just be sure both Ap and Pe are 75xxx m).

The fastest time from launchpad to being docked wins. Rules: No mods No cheats (debug menu etc.) You must dock to a station in a 75x75km orbit Your craft must have a Mk1-3 Command Pod No part of your rocket can touch the station before you are docked You must post a video of your entry (screenshots are allowed, but in certain situations I might request a video) Scoring: The score is the MET (mission elapsed time) when the camera changes, after docking the two crafts.

Hey, I'm trying to make a new clock, but I need some help. I have a reaction wheel that can roll freely by using a thermometer hinge. But I use if for some kind of escapement and when the teeth (antennas that I've placed on it) hit something, the whole thing is bouncing a few times before stopping. Anyone has any ideas how I could add some friction to it? (hopefully that will stop the bouncing) I've tried to place thermometers around the reaction wheel, if I place them radially, the friction is not smooth, if I place them on the flat faces of the reaction wheel, I don't get any friction at all. I've also tried to place the thermometers of the hinge closer together, but that makes the hinge unstable and doesn't seem to add any friction at all. I thought about using landing gears, but they are too big and they don't fit well inside the whole mechanism. EDIT: I've solved the bouncing by making some kind of ratchet. Added an antenna that slows down the gear before the correct position and after that blocks it from rotating back. Still, if anyone has an idea of how we can add constant friction to the thermometer hinge, it might be useful for other things.

I've never shared my craft files, but it might be a little disappointing anyway, it has a lot of parts, so it runs in slow motion, everything in the video is speed up a lot. I could make some pictures or another video to show in more detail how it's working.

When I've made the escapement I've aimed for one second per tooth, with 12 teeth per wheel it was pretty close. To calibrate it, first I was comparing it's ticks to the game time, when a new minute was starting, I was starting to count the ticks of the escapement and after 60 ticks I was looking again at the game time and if more or less than 60 seconds have passed I was adjusting the Wheel Authority on the reaction wheels. This didn't took too long, since the Wheel Authority can be adjusted while the clock is running. But after that I've let it run for 1-2 hours a few times and made finer adjustments. PS: Only one reaction wheel is keeping the time, it has 12 teeth and makes a complete rotation in 12 seconds.

I've made it so I have to set the trim only once (rotated the probe cores in such a way that they spin in the correct direction when I decouple everything) and after that when I stage, the clock is starting. To make it run faster or slower I adjust the Wheel Authority on the 2 reaction wheels of the escapement. It's kinda strange how the escapement is working, in a real watch you have a balance wheel, but in KSP I wasn't able to make something similar to a balance wheel, so I invented that escapement. It has 2 reaction wheels, one is spinning clockwise and the other one counterclockwise, let's name them A and B, when A is stuck in the escapement, B is rotating, it's releasing A and gets stuck, A starts rotating, it's releasing B and gets stuck and so on. If you go to 0:07 and change the speed to 0.25x, you'll be able to see this pretty well.

Thank you! It's having an escapement made out of 2 reaction wheels, you can see it at 0:08.

Well, it took a little more than just "today" to make it, but here it is: I've also made THIS TOPIC if you have any questions or you want to say anything about it.

You might want to check this:

A clock that I've made, it has a triple axis tourbillon, it shows the minutes and the hours (only 6, because it's showing the time from Kerbin), it's at the North pole and it's rotating so it keeps pointing towards the sun. It's completely stock, the only mod that I've used after making the clock was KerbCam for the intro scene of the video. Thanks to Luizopiloto for suggesting the song and to Majorjim! for inventing the thermometer hinge. I was able to synchronize it almost perfectly to the Kerbal time (interface time), but for the video I had to slow it down a little, at the end of the 7 hours it was 7 minutes behind the interface time, but still around 5 minutes ahead of the sun. I'm not sure why this was happening, I think the support was drifting slowly on the ground.

Nice editing. Can you explain how you've aimed for the Kerbal Space Center for the last landing?

A few days ago I've posted a video with a "clock" that had only a second hand. Meanwhile I've improved it a little. It's not very accurate (compared to the MET time from top left of the screen), it gained around 8 minutes in 2 hours and a half, but it can be calibrated, it just takes a very long time to do it and it's kinda useless. I've also made a topic about it HERE, where you can also find a video that is showing how it's working (although I wouldn't recommend you watching it, because of my horrible English) or if you have any questions.

Thank you.

Check the link under the first video, I show it in real time and I explain how it's working.

I've modified the first post, added a video with a new version of the clock, that has three hands and also added an "explanation" video, but please take the ... disclaimer very seriously before you start it.

Thank you for the nice words. You motivate me to try to add an hour hand to it. I'll come back with a video if I succeed.

This is a pendulum clock I've made, it shows the seconds, minutes and hours. Everything is stock, done on a fresh install. I've decided to make it after @luizopiloto showed me his VIDEO and suggested to me to make a clock. So I've added an hour hand since the previous video. Everything seems to work pretty well, but it's just not calibrated properly (it gained around 8 minutes in 2.5 hours), it can be calibrated and I could do it, but it's not really useful and it takes a very long time, because the game is running in slow motion and it takes a long time to load, every time I "launch" the clock. Also, if you want to see better how it's working, I've made this video: ***WARNING***EXTREMELY BAD ENGLISH, ANNOYING VOICE AND TV IN BACKGROUND***WARNING*** Explanation video (I start the clock at 10:40) ***WARNING***EXTREMELY BAD ENGLISH, ANNOYING VOICE AND TV IN BACKGROUND***WARNING*** OLD POST: I've made a pendulum clock. It's showing the seconds and the minutes (you can compare them with the MET from the top left of the screen). In the 5 hours shown in the video (the video is speed up to 60x), it remained only around 35 seconds behind the real time (the longest calibration run was 15 minutes, so probably I could fix this). It has 759 parts. If it gets boring skip to 4:30 for some nice shadows. https://www.youtube.com/watch?v=G2ugmoMK7oY And a picture showing what its components are. The "Spring" from the picture is actually a reaction wheel and by having the roll trim set to maximum (you can see it in the video), it spins by itself.

It has a few reaction wheels (the main one where the escapement is and a few smaller ones inside) that act as a spring would in a real clock, you can see me setting the trim (bottom left) at the start of the video, so they spin by themselves. It starts with the pendulum stopped (centered), the escapement (the thing with one gear and two strange teeth above) counts the oscillations of the pendulum, but also transfer energy from the spring to the pendulum. In Kerbal there is a lot of friction, the pendulum would stop after three swings or so.

A clock (sort of). I'll try to add a minute hand tomorrow. EDIT: Forgot to mention, it's stock.

https://www.youtube.com/watch?v=twbzqnfDQso I did it on stream, with full explanations, but it took around 3 hours, speed it up to 9 minutes on youtube, it's a little hard to follow what happens. Also forgot to skip checkpoints on that timer from top left. One of the most confusing parts is at around 3:30, so to explain what I was doing ... when I launched from Duna, I rendezvoused by mistake with a separator, instead of the transfer stage that I left in orbit. But I knew the transfer stage was a little behind on orbit, so I circularized the orbit at a little higher altitude and waited for the transfer stage to catch up and when it did, I rendezvoused and docked with it (at around 5:00). The only mod I used was that thing that shows you little dots for planets and stuff when they are far away (forgot it's name). I did it before without it, but that's not even realistic and it's annoying, to not be able to see other planets unless you are really close to them.

2 minutes and 8 seconds, but it's done in some old version, featuring Scott Manley's failed troll attempt in the comments.

I don't think they are required.
