    The Sun (GBC) Instructions

    There are a number of versions out there with GBC even input/output going on. To be honest, it is a very simple conversion. You may want to look into @Doug72's hopper mod, to stop ball jams. You will also need to either reinforce or change curve at the top of the run. Using the original rubber bars will cause it issues over time at an event. Which you can do without.

    GBC General Discussion

    Since this issue has come up in this thread, it seems even the LEGO Technic designers don't know about aligning their Universal Joints properly. The instructions tell you to do it incorrectly, which causes lots of problems. Probably an issues introduced by the person creating the instructions, rather than the designers themselves. That said, I am surprised this made it past testing.

    I have to say, I enjoy watching this. I think it will serve as inspiration for other modules using the same mechanism. Very nice work.

    I've had my first instance of hot linking. Not entirely surprised to find that it was China. It was linked to via: bd.pan.baidu.com/v1/od/queryrapidinfo?type=0&appid=offlinedl&scode=offlinedownload&source_url=http%3A%2F%2Fkanatta.com%2FGBC%2FTheSun%2Fdownload.asp Will be interesting to see if it occurs again, or they realise that hot linking isn't going to be a thing.

    @Ethan M Which module are you doing? At what point in the video? Or is it from a different year?

    Don't worry, I know this approach is OTT. At this point, I want to be able to bounce it down the stairs and it not fall apart. That said, it is already half a kilogram in weight O_o; Might shrink down the triangles down to 3x3 instead of 4x4 and thus reduce some brickage as well. Still way lighter than the wooden board it currently sits on :P

    This is basically what I am thinking about for the Akiyuki Ball Factory support structure. I am going to be doing it in black, but that is a lacking colour for illustrative purposes. The red represents where the ball factory touches the base plates. Triangular pieces sit below the top Technic bricks and above the bottom ones.

    Have to admit, I have never gotten a ball stuck under an arm. I guess it could shoot out of one arm and land under another if the other arm was risen at the time.

    Slower will make it happen less often because it is running.... slower. In fairness, due to how the issue manifests itself, it will actually occur less often at slower speed, but it will occur. I will give it a shot at slower speeds, but I am almost 100% sure it will still occur. One of the interesting things, is the fact that the way it fails rarely ends in it self destructing. The balls just end up in weird, unobtrusive locations.

    hehe. Mine can run perfectly on occasions. Other times, it is like a roid-rage baby in a cot full of toy. It ain't taking no prisoners.

    Finally finished off Cup-to-Cup v1.2 Finally got around to sorting the exit ramp. It is only a 30min hack of what was there before, but it gets the job done and it is a lot more rigid. The Akiyuki version had bits which rotated and all sorts, which I am not keen on. Runs they way I imagined it would, which is pleasing and it doesn't leave behind any balls in the hopper. The keen eyed viewer will notice that the spiral lift is a bit wavy in motion. I actually had the universal-joints aligned incorrectly. So I have fixed that since and replaced the axle, with a straighter one, whilst I was at it. Is the spiral life super smooth like the rest of it? No. Since it is now furthest away from the motor and is at the end of all sorts of gears, it is not perfectly smooth, motion wise. That said, when it comes to watching it in action, I far prefer the cups to be the smoothest part of the system and you don't really notice the spiral. Also the spiral motion is impacted by the friction caused by lots of balls in the hopper. I may well replace that one bush in the gear system with a black one. The way the balls slowdown midway along the 2nd ramp is amusing. This is an issue you have with this style of doing ball channels. Since the ball doesn't touch the bottom, just the edges, they rotate really fast. Thus, by the 2nd ramp, it is a fight between gyroscopic rotation, gravity and friction. I kinda like it as it adds an extra novelty to the module. Will adjust the 3D model so it has the new off ramp, instead of the old one and then set about doing the instructions. Most of the instructions are identical to the original version, so hopefully there won't be too much work to do.

    I am going to change the axels on Fork-to-Fork. I have built myself one of @Berthil's. Not exactly the same, but I worked with the pieces I had to hand :P So, once they are replaced, I will see if it runs smooth as silk. If not, I may also change the gearing arrangement on it. I feel as though it would work better with an even number of forks, rather than odd, but I am guessing dodgy axles are the main issue.

    Yeah, it is a seriously flawed design in that regard. I think, if I was going to try and fix it, I would redesign the way the balls are fed into the arms. Have it so it each one is independently fed and only allow balls in at certain timings. The issue occurs when the ball lands just as the pump is reaching a ball's width from the end, thus it traps it before the ball is sitting between the liftarms. As the arm raises, the pressure increases and since the ball isn't secured properly, it just fires out in a random direction. The machine works perfectly, if the timing is roughly okay. You don't want the timing perfect, as it is nice to see the ball sitting in there for a moment or two, doing nothing, or with another ball, it triggers almost instantly. That said, for the period where the arm is close to or past the width of a ball, the ball shouldn't be allowed to enter.

    The input isn't the problem really. Yeah, balls end up hanging around there, but it is the fact that as the arms go up, the balls can be ejected out the side. This often leaves balls in the undercarriage or balanced on some of the moving parts. You see this at every event it appears at, including the ones which Akiyuki attends.
