I was able to reduce weight on the design of the ball lift. I could swap out 12 pin connectors, 4 1/2pins and 2 axle pins with 4 3L pins. I also swapped 2 1x8 bricks with 2 2x8 plates. It makes a lot of difference, it runs a lot smoother. @HRU_Bricks For the lift of the ball cup rotator and cleaning clamp you will need an extra pneumatic switch. I see you have changed the mounting of the m-motor for the ball lift, vertical in stead of horizontal?

@Courbet Congratulations on the build and thank you for sharing instructions. It looks really amazing.
-
@Berthil Thanks, that was exactly what I was looking for. I’m not planning to build the invisible lift, but I found your alternative ball feed very clean.
-
@Berthil I noticed you have changed the ballfeed on the invisible lift with black tubes in stead of bricks. Would you mind to share a picture how you mounted the tubes to the frame of the invisible lift? I would like to use this solution in combination with your ball catcher feed module to create a loop with my ballcleaner module.

Thanks. 30159 is available in dark grey, so that might be the correct part. As part 8 is only available in blue, red , white and light grey. Any thoughts on the black parts? Magnet holder tile?

I can’t seem to find the red marked parts. Anybody got an idea? https://bricksafe.com/files/Juroen/building-tech/5FEAA65F-94E4-48CD-95C8-B92FE4504E54.jpeg/1920x1440.jpg

Thanks @HRU_Bricks Ok, I tried the 8 pumps compressor on the ball cleaner. Pressure drops really fast, I think a dual compressor doesn’t work either. I’m considering on buying an airbrush type compressor.

@HRU_Bricks I have send Akiyuki an email with a picture of my progress and some questions. Up till now I have received 2 emails from him with some additional pictures. Here’s a link to my bricksafe, I will add some pictures along the build. https://bricksafe.com/pages/Juroen/building-tech Building a Lego compressor is a big guess for me. I will see where this takes me. Could you share some pictures and information about the automatic shut-off switch when the compressor reaches the preset pressure? I’m planning to set mine to 2bar, the ball cleaner operates between 1,5 and 2,0 bar. Do you have a video available of your ball cleaner module? It looks quite impressive already!
-
Seems to run ok! I received some photo’s from Akiyuki this week. I made some minor adjustments to my ball lift, so I now have a 100% exact copy of his design. It does make a difference though in which direction the motor runs. In one direction it runs smooth and in the other direction it has slightly more resistance.

@Lego_GBC_NL You are right. My goal is to build a compressor only using official Lego parts, except from the hose. Compressor will be the same height and length as the ball cleaner and connected on the back side of the ball cleaner. My guess is that a single Quanix compressor will not suffice. Provisions for a double compressor are made.
-
Started to work on a combined Quanix-Akiyuki designed air compressor.
-
Looking great! Another Akiyuki mystery solved!

How is the setting of the 9V controller during exhibitions marked so that others can start and stop the GBC modules? Is an on-off switch always used? Are there some examples? -
He had the same problems in 2015; mark 0:42 & 4:10 He somehow managed to solve this in 2017; mark 3:38

In between building a compressor for my Akiyuki ballcleaner, I’m tweaking some parts of the Akiyuki ballcleaner design. The first stepper is an exact copy of the Akiyuki design. However as you can see in this video there’s a problem with the vertical movement. When the stepper is moving up, the motor struggles to get it to the top due to the weight of the stepper. With a XL motor I have the same problems. When I hold this part horizontally it works just fine. Also tried some different gear ratio’s. I was thinking of using some kind of counter weight, does anybody have any experience with this kind of stepper?
-
I only tested the functionality with a manual cylinder. I just ordered parts to build a Quanix based compressor. I will have to see if that works, otherwise I might be using a non-lego compressor. Probably some kind of airbrush type compressor.
-
@HRU_Bricks Looks great! I still have to start building a compressor. So far the ball cleaner project has been standing still for almost 2 months.
-
A video will be available once I have built or bought a compressor.

GBC General Discussion

Is it customary to name both the designer and builder of a module during a GBC show? Is there a standard for this? Printed tiles for example? -
Thanks! Indeed a mirror image. I doubted for a long time to add any mini-figures. I thought that might be too much. Technic 40 years is much more subtle in my eyes. Ball path is 2 studs off center towards the back.
-
It took me almost 6 months to build and today I have finished the Akiyuki ballcleaner.
-
Yes, all motors are running fine on the EC3-brick. Last thing to do is build a compressor.
-
The webshop where I bought my pneumatic hose was down for almost 3 months, so I had to wait for them to reopen. As I wanted all hoses to be the same type. I thought that 5 meters would suffice in the first place. But that is not nearly enough. So I ordered an extra 5 meters.
-
I finally ordered the last pneumatic hoses, so I can finish the ball cleaner and start on the compressor.
-
@HRU_Bricks I like your work on the compressor!
