    There is a section at the end of the vid, which you almost want at the start, an angle which most people at an event would see it from, being able to see the balls pass through! Great work!

    The tipper at the top is a really nice touch!

    It is an easy build. The only daunting part is sorting out the timings. I found that was the case at first, but having fiddled with it so much, it doesn't worry me any more.
  4. Ankoku
    Yeah, that looks correct. Good spot.

    I could easily believe it is a Bionicle piece, but I suspect it is 3D printed, especially considering the colour.

    @AFOLegofan66 What are you planning to try?
  7. Ankoku
    I mean within the Akiyuki machine, after it has gone through various gearing etc. I am sure it can go much faster than it is doing in that vid ;) e.g. with the one in the vid, I suspect it is using a worm cog. What is the white piece in front of the motor?

    It certainly helps. Managed to have a ball properly jam and rip part of the machine apart the other day. There is nothing wrong with the design of the wheel. It is far more to do with how I am feeding it and the space and height restrictions I am working with. So I am going back to the drawing board for the minute. I am pondering trying the long arm of this: It is amazing how differently some parts of the machine act at different speeds. Momentum being what it is, it is fairly obvious that it would occur, but it still surprises me at times. When it comes to the bucket ball dumper, I couldn't replicate what I was seeing in the video and it was only after all sorts of changes did I realise it was just a speed issue. Do it at full speed, it is identical. The only problem is, at full speed, it is hard to see it is moving so fast. I do wonder whether the design above is going to start flinging balls, rather than dropping them at full speed :P

    Hadn't come across this one before. I like the idea of it though.

    You could actually run an NXT which keeps track of motor RPM and stops the motor and sets off and alarm if the RPM drops dramatically for more than X in time. Press the main NXT button to reset and start the motor off again. You can also charge/run it off the mains.

    Been hand cranking the ball factory without the wheel and disconnecting various parts to see where the strain is. As far as I can tell, the main offender is bring Bob back from the wheel to the bucket shifter. This motion is done at the bottom point of this mechanism: You can see the connector near the bottom of the vertical axle, obviously, it has far less favourable leverage when at the bottom. The plastic doesn't strain, Bob moves very free and loose, but you can hear the slight strain on the motor when it is moving through the lower section of the axle. I don't think this is avoidable. Just part of the design. it isn't much of a difference in torque, but you can feel it when hand cranking and you can hear in with the motor.

    This feels more like a treating the symptom rather than the cause. e.g. you see the wheels jamming in the video. For the mini wheel I am working with, I seemed to have prevented any jamming as the ball exits, but not quite sorted out the loading yet. I feel like a timing mechanism is the best bet. It is purely a personal thing, I just don't like seeing things get stuck, so I want to try and avoid it in the first place. One thing I wish they would move towards at GBC events, is the most unique modules, rather than just the most modules. Having 50 of the same module seems to be against the spirit of it in a way. (Apart from when they do the "make your own GBC module" at the event.) @Great Ball Pit I loved your LEGO separator tool wheel. Ingenious and aesthetically pleasing!

    I need to run it without the main wheel. As far as I can tell, it may be the only thing which makes the motor noise change. When hand cranking it, it feels pretty consistent. Nothing is catching, nothing is flexing.

    Not the best lighting, there isn't much difference between thw two, other than using the light on my phone for one of them. I apologise for my lack of balls! Way back when I bought them from LEGO, I thought 30 was all I would ever need :P The loop back is currently using @sawyer klegr mini loop wheel. The way I feed the wheel currently, can eject a ball, so it isn't reliable. Some of the changes you see are from new versions of the Akiyuki Ball Factory. A couple of them are done by me to make it more reliable. Bob I believe can drop the bucket perfectly every time. I just haven't adjusted where the arms sit on the horizontal axel. Never had an issue with the ball droper. Seems to be rock solid. One other thing I noticed, is that a bucket can raise slightly on the back when as it pushes against the yellow blocker at the end of the conveyor belt. Only seen it a few times and I think it can be fixed by changing the height of the blocker. Only seen it happen a few times.

    Not LEGO, but nice video for inspiration. Have spotted many techniques seen in LEGO GBC. The video contains many machines, many of which are modular, which is quite cool.
  16. Ankoku
    Mine is mainly going to be loop back, but my mission with fixing it up, is to get it at more events. It is my favourite GBC machine, so it would be nice to see it around more.
  17. Ankoku
    At the minute, it seems reliable if you are using it with other GBC. The loopback, which isn't in the original has a few potential issues.
  18. Ankoku
    Yeah. Had to clear some space on my phone to create the video :P Will most likely post it tomorrow. The ball dropper is rock solid now. Also improved bob a bit, in terms of placing the bucket properly and not disturbing other buckets.
  19. Ankoku
    What are the main issues that people face when running the Akiyuki Ball Factory over long periods of time? What are the reliability issues? Other than ball dropper. I have fixed that.
  20. Ankoku
    I am curious about this one. Is it a chain wear and tear issue? Or an issue in regards to their weakness if something gets jammed? I think the main rule is to only design things which can't jam due to ball randomness. I am currently fighting with how a ball enters a lift wheel. Every now and then, if a ball hits it at just the right time, it jams. I don't think I can avoid it. It does fix itself, but it does so by firing said ball out of it. So you end up with random balls ejected from the system, which is less than ideal.

    Shame it requires 4x RC Buggy motors to power the beast. Great work though and it is an excellent video, looks so much fun to drive on ice. Love it!
  22. Ankoku
    I am guessing the instructions video is basically being played in reverse and it actually shows you taking it apart?
  23. Ankoku
    @Berthil The Bricklink URL doesn't work for me.
  24. Ankoku
    Yeah, the turn-table version of the cup to cup looks really nice, very stylised. Do you pin them together as well? Or just the axle and halving the load? It feels like we are discussing the strengthening of transmission axles on Technic rock crawlers.
  25. Ankoku
    I am guessing it gives the gear a bit of give when putting axels/pins in it. e.g. user friendly for the casual/child builder. I believe with 3648a you could put offset axles through the hole on either side.
