Back support for the gears and ramp is done, along with the drive mechanism sat underneath. What isn't physically built yet is the new underside to the hopper. Going to finish it off digitally, then work out what I need to buy before finishing off the physical build. I think all it will end up being is some grey bricks.

Lego GBC Cardan Gear Module
Ankoku replied to sawyer klegr's topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
From LEGO? They can be really random with B&P. Interestingly, you can get free postage for it, if you are spending over £50 usually, or currency equivalent. So I ended up doing a B&P order and then some extra motors to make up the amount. They are posted separately. One thing I don't like, is that you only get an invoice once it is shipped, which is rather disconcerting as that can take a while. The main thing I hate about the LEGO B&P site is that it times out so quickly. It could be so much better, but I suspect they keep it as bad as it is to keep orders to a minimum.- 41 replies

I do like how he goes back to his modules and addresses various issues with them. He seems to do it with most of them. The new approach seems to be far smooth and notable faster, which suggests he may have completely changed how it is done.

The first thing I do, is see where you have the same issue in his video. If not, then you need to be looking for something which is amiss with what you are doing. Probably good to check that your axles are straight and non-tacky. Could potentially use some form of lube for it. I know with my axles some can feel very different to others when you run your fingers across them. Potentially you could have a runner at the other end, so all the weight isn't hanging off one side at a slight angle. Also, could something like this be used: Which is lighter?

@skppo I don't think GBC is popular with the masses, it is mainly just popular to see at events. That said, do I think that LEGO will do an official set one day? Sure. It will most likely be something which only moves a few balls around though, since balls are expensive. @Lego_GBC_NL The Sun worked great straight out of the box to be honest. It was only my own mistakes in reverse engineering it which has created issues. @PG52 did a great job designing it. My main issue with the Step thing is that it is not how you naturally work. So in many respects, it is very much a post design thing. e.g. I created all the steps properly for Cup-to-Cup Type 1, via following the instructions. That said, the moment I started making big changes to bring it in line with the now current version, the whole step thing has become a giant mess. Stud.IO needs a step editing mode. Where it is much easier to move the elements between steps. I always knew about the ratchet system, as it is one of those things where I wanted to change the colours. That said, some of the colours are not available in the colours you want. In the end, I realised my build of the model (Maybe not as loose and smooth as it could be) didn't need it. Unfortunately, it is not as easy to remove from a fully built model as you might hope :P I was hoping for more photos of the sign at the top, which says "The Sun", but apparently it no longer exists. Not sure if it got cannibalised for parts or took up too much space for storage/transport etc. It is an almost purely cosmetic aspect of the module, but I like it and it does add a bit of counter weight, but it isn't really required and probably makes the motor work harder. The additional images are on BrickShelf on his page. I didn't really post about building it, as there isn't much point. I certainly wasn't going to release instructions until I had built it and tested it.- 1,124 replies

@Lego_GBC_NL Does this answer your question? The keen eyed will notice the bottom feeder ramp is actually incorrect. Since doing anything at funny angles in Stud.IO is a royal ball ache, I hadn't attached it all together and thus got the length wrong. So I am waiting for my next BrickLink order to fix it. Once fixed, I will test it and then set about creating the instructions. Everything is currently in one HUGE step, which means there is quite a bit of work ahead for the instructions. I started working on some other projects, fixing things, learning how to do the step stuff in Stud.IO based on how others have done their instructions. Unfortunately, fixing the Cup-to-Cup Type 1 has become a thing and thus I won't be doing a BL order until I have worked out the digital file for that. As it stands, it works perfectly, other than that bottom ramp, which is wrong. There, it can pop balls out on the far right and it needs X amount of balls to push 3 into the shifter, since the ramps left end is a bit too low. All of which should disappear once it is at the right length and thus the correct angle. I enjoy it as much in real life as I do in the video and I was either really lucky or the thing basically self syncs as you build it. e.g. no syncing is required to make all the elements work in time with each other. PG52 helped with some additional photos of it which really got the ball rolling. Unfortunately, it seems life as got in the way, but I managed to pretty much work out the upper part. I have only made 2 modifications. One is with the elastic band at the back. The other is with how the top ramp is supported at the top, which PG52 felt could be changed. My change is basically to force it a bit further away from the wheel. I am just leave the instructions as it was in the original version though, as it is incredibly minor. Oh and I actually removed the ratchet system. My wheels may be stickier, but it just seemed redundant and made a lot of noise. Again, I may leave this in the instructions to keep it true to the original, especially since it is only 9 pieces and they aren't uncommon. It really is a beautiful piece of work and I hope he does find time to convert it so that it can be used in a GBC event. It may just be me, but I kinda like it when the original creators do these conversions. If he does, I will obviously do a new version. Apparently the "The Sun" sign at the top is no longer a thing, but I like it and it provides some useful weight to help the elastic band do it's job. As for PV_Productions, I thought their original lack of credit toward PG_52 was a bit lacking. So it is nice to be able to let people be able to build this without having to pay for it.- 1,124 replies

After far too much staring and zooming in and wondering and staring at the ceiling in bed, I think is may be what is going on: Basically, it has a silly amount of bracing for various aspects of it. The 4x Technic, Liftarm 3 x 3 L-Shape Thin is purely speculation as I have no way of seeing it in the resources I have to work with. That said, it makes sense and places the spiral rotation part at the right height. The 2 liftarms which sit below the L-Shapes are still a bit of a mystery to me. I don't entirely understand their purpose. Maybe even more bracing? Seems a bit redundant though. I still don't know what is going on here either: This is at the bottom of the vertical bracing for the tower, The dark line is the usual line between bricks, but you can see to the left of that, there is another, lighter line which is very close. I have no idea what is causing that.

Thought this might be it, but it doesn't match up. There is no space for the vertical bush after the gear.

They are pretty cheap, since few people have a use for them: https://www.bricklink.com/v2/catalog/catalogitem.page?P=x494&idColor=43#T=S&C=63&O={"color":63,"iconly":0} I like the fact that I am not really interested in whether the ball goes in the basket or not. I don't mind the EV3 in this case.- 1,124 replies

Currently trying to do the underside of the hopper. This is an Akiyuki photo: This is how far I have gotten: I thought the piece the arrow is pointing to is this: But if you look closely in the photo, you can see some grey there, so it isn't a black one of these. That leaves me thinking that they may be thin liftarms? To be honest, I have no idea why this who assembly in the red circle exists. It is mirrored on the other side. What is it's purpose?

I came across the issue when fixing the Ball Factory issues. I couldn't work out why my conveyor belt was variable speed, when it wasn't in the video. It was a universal join alignment issue. In the end, I replaced the universal joints with a chain driven approach to remove any aspect of variance. Generally, where possible, using 2 universal joints is better than one, if correctly aligned.- 1,124 replies

@9v system Remember to post the Akiyuki images to Flickr/BrickSafe/Brickshelf Such photos are always important. I am really glad he does them. He must get inundated by us pestering him on occasions.

@yoyo08190 Are you still around? Do you have any photographs of your Cup-to-Cup v2? From the front, behind, underneath etc.? I like how you too have changed the hopper to stop balls collecting there!

I did not. I can see a few things in his version that stand true to the most recent version of Akiyuki's model. I might give him a poke, see if he is still around. Thanks, that is an awesome fine. I have just started to make the drive mechanism in real life and have decided on a personal mod, which isn't in the original. You can see it here. The top version being the original. The reason for the change, is because it stops there being any rotation and that rotation could cause friction and thus resistance. This clamps them down nicely and although less elegant, I think it is worth it. Also gets rid of the ugly blue :P (You can use a black piece there, but they are really expensive.) Thankfully, it doesn't jump outside of the normal bounds of the module.

I am currently facing the same issue with Cup-to-Cup Type 1, taking screenshots from the same 2015 video. The 2015 video is the only one where you see the back side of it and even then, only at a distance. Both with the ball factory and cup-to-cup, I am spending time in photoshop, trying to make certain aspects of fuzzy video frames stand out more clearly. I am currently still scouring YouTube for other people's video footage of Japan Brick Fest 2015, 2016 and 2017, which are the few places where it appears. My general approach is: Does it move as well, as smoothly as it does in the video? If not, something is amiss. It took forever to finally work out what was wrong with the ball dropper in the Ball Factory, but I finally got there in the end, removing a notable amount of resistance in the process. Sadly, that fix broken the feedback loop as there was no longer room for it :P The amount of work left to do on Cup-to-Cup is rather daunting. Got to sit down and redo chunks of the hopper and support structure. I am not looking forward to it.
