  1. A really big 3D printer has some problems... I don't exactly know how these machine works but I could imagine that it could move around which is really bad. If it doesn't, that would be really awesome. Another thing is the print time. Don't underestimate the time it takes to print large stuff with a 3D printer! I am now waiting for my ISP Programmers and trying to align the central plate with the axis but I am not sure I will be able to get it accurate enough...
  2. Good idea! That would also simplify calibration. I could simply send a Signal to let the controller know I want the axis calibrated and the microcontroller does it on its own and i dont need to use extra cables for the photocell. Tomorrow I will get the audio connector and I will order a progammer for the Attinys I have lying around. EDIT: I just got the Audio connectors and now i´m working on the middle plate but i am having some problems aligning the axis accurately.
  3. I Changed my plans and decided to contact the inner plate via a stereo audio connector and a 1 wire bus and the U clamp assembly via this Slip ring assembly: 4 Rings are for the pitch Motor, 2 Electricity for both motors and one is the 1 wire bus. I am now waiting for the Audio connectors to be delivered and thinking about how to realise the Bus. If you have any idea how to transmit 4 bits as often as possible per second over 1 wire, please Write it here! Thanks
  4. anyone else?
  5. Do you know any workaround to get 2 seperate views working at the same time for a simpit? I want to view 2 views at the same time.
  6. Is it possible that you implement it that you can show 2 cams side by side?
  7. Yes, if you dont rotate it too much it will work but i would like to make it (if possible), that it can rotate forever in one direction. BTW I think you can get more than 360* with very thin stranded wire. How does it work at your school that you get money for Projects? I once participated in a competition with my school and I had to pay for the parts myself . Google translate is awesome
  8. I dont think that would work because if the Pitch Motor rotates the cables will tangle up or how thats called in english. You cant rotate one side of a cable while holding the other side for more than a few rotations. I didnt do anything last weekend except for a list with the stuff I want to put on the panels qhich inst even completed yet. But next weekend we have 2 weeks vacation so ill try to use that time and do something.
  9. I ran into some problem but I may have found a solution... The Problem is: a) it is very hard to get the plate perfectly 90* relative to the axis b) I am not sure if the way I thought I will build the contacts will work. I added some epoxy glue I mixed too much and put it between the rings to prevent the springy contact from slipping of and put it together with tape but I can't get a good contact. I will try it again tomorrow but I am also thinking about using a tube on one side and putting a cable through and then transmit a signal over a single line and decoding it in the ball with a attiny85. Of course i would need a way to get the single line outside but that would be a lot easier than 4 lines. I could do it like this: If you have any Idea how to do this let me know...
  10. I just finished the Slip ring: maybe i will make a notch instead of a tab for calibration...
  11. Here is a picture of the C-clamp: The white Thing in the upper right contains a Ball bearing and the bar holds pieces of spring Steel against the contact plate which I am working on now. UPDATE: just finished etching the contact plate, looks nice, tomorrow I will add some rings between the copper rings to prevent the contacts from slipping off.
  12. Thank you again gor the explanation! Its already too Late to change it but on the real Apollo one, the rate meters at the edges could display 50 degrees/s max so I think Apollo was moving at that speed. If I think of a capsule spinnig at 0,5 rpm, that seems pretty fast if you are not in ksp. I'll make some pictures after school and try to get the contact rings done. I think i'll print a Round part with 2mm height and some rings around the centre to seperate the contact rings. In the places where there is no seperation i put in a thin sheet of copper Or aluminum. I know this explanation was horrible but If I'm finished I'll post some pictures.
  13. But if two of my gimbals align on the fdai and I move the "missing" axis, would that be possible? I think I didnt understand it because i dont know How this could work if i have 3 axis... Nice Idea with the camera! Do they move fast enough? I am using the cheap Chinese 28byj-48 and they move at around 0,5 rpm (2s per revolution) max. I think that's enough for me but I will also add a light which indicates that the fdai isnt at the real position and needs time to catch up. I am also not sure yet if I'll add photo sensors for calibration. I think it would be easy to build and I have some here but I dont know if I would need them. Maybe I'll have some pictures tomorrow.

  14. Thank you for the explanation! I am still not sure if I should place the gimbal lock region around the poles (probably easier to integrate in KSP) or if I schould do it like apollo (bettet for Launch and landing...) Yeah I am 3D printing some stuff, the C-Clamp is made out of aluminium (aluminum where the non-metrics live ) with printed connectors inside. The Plate between the two Arms is made out of acrylic (because I had it l lying around in the right thickness). I also printed the Part that holds the inner axis Assembly (It is a Metal Tube with Ball bearings at the Ends where the inner axis goes trough) and the Part to connect the middle axis Motor to the C-clamp. I am also printing the parts to connect the hemispheres to the inner axis at the moment ( 1 1/2 h to Go and already 2 hours printing just for the First part ...) I think I will print the second one tomorrow.
  15. Helle there! I am currently working on the FDAI and ive got a question: Why are the Circles on the Ball concentric around the gimbal lock Points and Not the Poles? http://www.collectspace.com/ubb/Forum14/HTML/000813.html In KSP it is concentric about the Poles, right? Also does somebody know what the diameter of the Ball is? I already made the U-clamp and today I will be working on the central plate. Thanks for your answers
