    Thanks! Thanks! The purpose of that is basically a clutch. The one 8t gear in the side that the power is coming from is attached to a friction pin. I made it this way instead of using a "normal" clutch or one of the 24t clutch gears because this way it completely releases pressure for a short amount of time. It is normally not really used, but it stops the module from jamming which occasionally can happen with the 12t gears that mesh with the start of the banana gears. This only happens when it is running at really low speeds. Would still be cool to see your module if it is working :)

    This lego GBC module uses a conveyor built out of technic engine block pieces to lift the balls. It is powered by a lego XL motor and fully meets the GBC standard, infarct it can actually run reliably at almost twice the required speed for the great ball contraption standard, although it runs more reliably at slower speeds. I originally made this module after chatting with some friends about how we all have so many of the engine block pieces that we almost never use any. This is basically a product of trying to use theme in some way. If you would like to build it I have the free instructions and 3D file on Rebrickable, created in BrickLink Studio. If you have any trouble feel free to contact me and I would be glad to help, hope you like the module! :) Photos on Flickr. Don't know what is happening with the Flickr and YouTube links but they are not working, here is the youtube video. https://youtu.be/nr-HMLtBgqU Lets see if this works..... YES! Not sure what was happening before.

    Hahaha, yes, I think that most technic builders have a few too many of them. I came up with this after seeing this car by R. Beckett (I think it was for a contest here a few years ago)

    Finally finished another one ;) This lego GBC module uses a large Lego technic sprocket on it's side to and lift the balls. It is a reliable module and meets the standard, it can hold over 30 balls in the input bin and runs just over 1 ball per second. The mechanism runs a lot smoother in real life then it look in the video, it also runs a bit better slightly slower. You may notice in the video that sometimes it doesn't pick up the full 6 balls. This could be fixed by changing the agitator design or running it a bit slower so that the balls have more time to roll into the sprocket I did not change the design because it is very reliable like this and still meets the standard.

    Thanks! This one was accidental, I came up with it when I was trying to make a turntable out of the sprocket pieces.
  6. sawyer klegr
    Yes, it is very smooth. I think it might be hard to attach a motor to it though...

    This lego GBC module uses the lego Mindstorms EV3 to power the module. It uses a robot arm style mechanism to lift the balls from the previous GBC module to the next one. It is quite reliable and has had almost no issues while I have been testing it. It is quite simple and small for a mindstorms GBC module but it is the first thing that I have ever made and programmed with it. (Do you recommend using the EV3 programming app or Python? I know Python quite well but have not tried using it for mindstorms before) I think it turned out ok for my first MOC using mindstorms, hope to make the next one much more interesting :) Instructions. Photos on Flicker.

    Thanks! Thank you! You can also flip them the other way and put 6 basketballs in the middle to make a turntable.

    Nice! Love the wall built out of the 1x1 plates, it looks so good and I imagine it was hard to build.
  10. sawyer klegr
    Yes, I don't mind doing that, quite often I run PF motors on low speeds so that I can save on gears.
  11. sawyer klegr
    That looks like a great design! It looks like it will be very reliable/accurate.You seem to have been able to get the mechanism quite small by using mindstorms instead of PF. I think that green 40t gears would be very interesting for building other non GBC MOCs like trees, Might have to get some ;) We are also not allowed out much here, only to go for walks/runs and to get food. Hopefully will not last to long.
  12. sawyer klegr
    Wow, sorry to hear that he had it, so glad he is better now! I have also not used my EV3 much yet because it is so different from power functions which I am used to, even though they look so similar. I do have one idea for what to build with it next though. Sometimes I feel like I am being "lazy" when I use it because it is possible to get the same motion mechanically.
  13. sawyer klegr
    That looks great! Sorry that I have been taking so long to reply, it has been quite crazy here over the last few days. Your new train module loos great, and more importantly like it will be very reliable. I hope you can figure out the mindstorms programming, I found it quite hard to get used to even though I can code using java/C#. It is meant to be simpler than real coding but at times I find it more confusing. Hopefully spike prime will be easier ;) I like your mechanism for keeping the bucket level using the large turntables. Is that red 40t gear like a normal one or is it similar to the red 8t gears that don't have friction? I have never seen them in red before. Also is your train exactly the same as Akiyuki's or is it a different design? if it is Akiyuki's that would be cool so you can use it with his other designs.

    I programmed it using windows 10, in theory it should not matter what OS it was programmed on, only if it is 32 or 64 bit (I think) I wonder if it could be a problem with Google drive not recognising the file format? Hope you can get it running, I think that it will look very cool if you can get it to load the train! (Is there any website that you know of that is “designed” for uploading EV3 programs to? That might help because if it is a problem with Google)
  15. sawyer klegr
    Wow, looks like you will have a lot of time to learn how to program the EV3, I bet your program will be a lot better than mine ?
  16. sawyer klegr
    Can you run my program on your EV3 or will the software not even let you do that? You would not be able to edit the program easily but at least it would save you from having to program it again. Good luck with the programming ether way, can't wait to see it finished ;)
  17. sawyer klegr
    That looks like it is going great! Hope you can get the program working. You might be able to program the arm to push the PF switch on by lowering the arm on it, it could potentially save you a extra motor.
  18. sawyer klegr
    That looks so good! Can't wait to see it finished. Sorry that the program would not run for you, I am also very new to this whole EV3 programming thing. I assume you are going to use the color sensor to tell when the train arrives? (Your mod using the technic lift arms instead of the plates looks like a good idea, I used the plates because I did not want it to be able to rotate. I think your way looks a lot stronger) Good luck with the programming, that is my least favorite part of using mindstorms ;)
  19. sawyer klegr
    That sounds so cool! I would love to see it when it is done! I think that the arm can handle more weight, especially if you add some kind of counter balance (or maybe use the small soft shock absorbers?) If it helps I have uploded the actual ev3 program here. (the link should work hopefully ;)
  20. sawyer klegr
    Thanks! I think it would work well for loading a train GBC. Sorry for forgetting to upload the code, I will do that now. (Yes, I know my code style is not very good ;) Can't wait to see what you build with your EV3!

    These two lego great ball contraption modules are designed to be simple and reliable so that they can easily be built by new lego gbc builders but still be cool and interesting to watch. I designed these GBC modules to be able to share the power/motor from one module, this means that you can easily power up to about 5-6 great ball contraption modules from one motor. You can also easily use almost any modern lego motor, including Mindstorms and lego powered up motors to power the modules. One of the reasons I built these modules is because I wanted to build some simpler modules that are easy to build. I hope you like it, if you want to build them I have made the Bricklink Studio file, part list and PDF instructions available for free on Rebrickable here: Conveyor || Stepper

    So glad that they made a new diff design, I always found the old design to weak.

    This lego GBC module uses two gears for the main mechanism, one with 16 teeth and one with 15. This means that the inner gear meshing with the outer one will rotate slowly and in lean from side to side. The balls roll onto the "forks" at the bottom with the use of a timing mechanism which is attached to the main gear. It is a reliable module when it is on a flat table, but it does take some time to set the timing right. I have instructions on Rebrickable here. Hope you like it!
  24. sawyer klegr
    The “15 tooth gear” is the large gray ring made of 1x4 and 1x1 round bricks, it is not actually a 15 tooth normal gear. (sorry, should have made it more clear what I meant) Hahaha, thanks ;)

    Good way to use the net pieces, have never thought of using them like that before.
