    My version of the Akiyuki Train Lift and Rotary dumper in one module leaving out the Lift bridge. The 'old style' Akiyuki base has added a lot of rigidity when compared to his original design. Still WIP but very close to finishing it, I hope to make 'studio' pictures and a video of it this weekend. In the back at the right also a new exit for the Invisible Lift which I think fits seamlessly in the overall design. More on that also this weekend.

    Impressive by size and attention to detail, rare to have a combination of both so well executed (and both night and day)!

    Nice! I'm not planning to build very much of the Akiyuki train layout unless it will fit in a GBC circuit but on it's own this all together is quite an achievement to be admired.

    Yes, it was my solution for the gap in August last year, just a 1x2 plate

    Almost. I have integrated the lift and rotary module in one module leaving out the (unnecessary) elevator ramp and making it more stable according to Akiyuki 'old style' building technique (which I like more and fits my other modules better design wise).

    If that's all I will rotate one quarter. In fact I already done it and tested it. It seems to run a little bit smoother but stil sometimes the first wheel forwards 1,5 and the next a 0,5 because of gear backlash. Thanks for the tip, I will also check my other modules! I line the joints up because I think it looks nicer as I have a tic that stuff needs to be symmetrical but I wasn't aware of this side-effect :)

    @Ludo Visser, thanks for pointing that out! I had thought of that but it would make the module longer and I had to recut the expensive 3mm hoses to longer length :) It will also make it more difficult to unload and load the cipher wheels. But I will try your suggestion and if the first wheel runs smoother because of it I will change the module accordingly. Thanks!

    Thanks you all for the compliments! Not sure what you mean there, which U joints? You mean the 1x4 and 1x5 thin liftarms under the chain? These can't be aligned because the wheels turn opposite of each other. If I align them one set will already turn the next wheel at number 1 instead of number 9. I didn't want to add more gears to have the wheels turn in the same direction because of added backlash and the opposite cipher wheel turning doesn't bother me. The cipher wheels are quite heavy with all that LEGO so I'm already happy with the way it runs now but I'm always in for improvements so please let me know if you see any.

    Just finished my GBC Ball Counter if you are interested:
  10. Berthil
    All mechanical and 100% LEGO Ball Counter. Numbers do not always line up perfectly because of backlash in LEGO gears but it counts every ball. I tried to minimize amount of gears but as many of you know, backlash is almost unavoidable. The wheels can be taken out the GBC to set to zero. 1:10 ratio mechanism by Parax77.

    I did not build type 1 but heard / have seen on youtube it is not very reliable. I have build type 2 (with instuctions from Courbet) and ran it for a week every day for 7 hours without problems. I only made a modification to the train PF switch by taking it apart and cut away the very small notches so the switch had much less resistance when switching. Without it it wouldn't switch half of the time. For version 2 Akiyuki also made the instructions himself and it seems more loading/unloading modules will be published by him. So I think version 2 will be the better choice.

    Nice idea to smoothly move balls up in a compact and timed way.
  13. Berthil
    I haven't used them in a GBC yet, just tried them right out of the received package. I will try to flex them up, I suspect they got compressed until the point where no balls pass through.

    Sorry, here complete link

    That's also what I thought. In my own design higher torque machines I tend to use two 24 teeth next to each other (connected with pins for even force distribution) for added strength like in my version of the Cup to Cup with turntables.

    @Ankoku Both 3648b type and and 2 break at the extra axle indentation. Don't know why that indentation is there, not really needed for anything, nothing fits through it. As you can see there is even less 'body' there with 3648a. Soon I'm gonna send my 5 broken ones to LEGO :)
  17. Berthil
    No, the dark bluish grey ones. The older light bluish greys are even weaker.
  18. Berthil
    I bought some of the x153 in trans black out of curiosity but in my tubes the balls don't go through because of the indentation. They get stuck. Have the hoses been 'modified' to lift some of the indentation? It only needs a little less indentation to make the balls go through, not much. Or are the hoses that were delivered to me too tight? By the way, to connect these tubes to anything you also need the connectors: https://www.bricklink.com/v2/catalog/catalogitem.page?P=30585

    Sometimes there is a weak 24 teeth gear and it can break. I've got 5 broken now in al my machines and also in the low torque ones. The Invisible Lift is a high torque machine, hence the presence of two white torque 24 teeth gears.
  20. Berthil
    Rebuild of the invisible lift is indeed not needed, just look carefully what arm or arms causes the problem and adjust gearing accordingly. I've done it a few times on breaking of a 24 teeth gear or after a 40 tooth gear had wandered of an axle. It will also learn you how to deal with timing issues as you probably cannot keep the motivation up to rebuild it completely every time after a timing issue.

    Flickr works again so also some photos:

    Here's my version, also got high res pics but Flickr is not working so later. @Great Ball Pit Thanks for the excellent idea with ramps and bucket wheel!
  23. Berthil
    It's indeed the mechanism by Parax77. Advantage of this mechanisme is that numbers stay put until they are ready to turn to the next number like in the counter of Fitzgerald which also seems to be a good mechanism although not all numbers line up in the Fitzgerald video. In the Parax77 mechanism the numbers stay lined up most of the time, they turn in two steps instead of 10 steps. Another advantage is they turn light if build well so no additional forces needed to use 5 wheels. In my version the wheels turn opposite, it doesn't bother me and I want to keep them turning as easy as possible with numbers lined up, no slack caused by many gears. Parts are almost all there so hope to finish it soon and make a video.

    Thanks! The gearing is between the wheels and is a really smart design by Pallax. As you may know agreement is a GBC must be able to handle 1 ball per second but that doesn't mean 1 ball per second actually goes through the machines. That's an ideal situation and very rare in a GBC circuit with multiple machines because there are always hickups as you know :) You have a video of your counter?
  25. Berthil
    I'm busy making a mechanical ball counter GBC and designed the below cipher wheel. There will be 5 of them so counting to 99.999 because per event day about 26.000 balls can run through a GBC. Each cipher wheel can be taken out to set to zero because I don't want to turn the wheels back 26.000 times and the end of the day. The mechanism to pass on 1 turn per 10 turns is an excellent design from Pallax. When more parts arrive I hope to finish it soon and present a video.
