    The main functions for the cleaning machine are complete! Some fine tuning to do but it is working really well. The machine is running 100% mechanical at this stage. The next step is to build the lift for the ball cup rotator and the cleaning clamp. Video --> https://www.bricksafe.com/files/HRU_Bricks/gbc-ball-cleaning-machine-project/VID20190802211107.mp4

    Hello all! My first post in the Akiyuki Train Module thread and I thought I would start with the loader. I did make some mods to the beams in the frame. Originally the supports were on an angle however I did work out a way of framing them so it did end up with a cleaner look and stronger. @Doug72 Thanks for putting an index on the 1st page. I am looking to build the un loader next. Is there any other mods to make it better? Thanks

    It is another great model from him. I do wonder how long they take him to design and build. Even I don't build the model just going through the instructions is a great way to learn.
  4. HRU_Bricks
    That sums it up! It is a good thing what they are doing, it opens build possibilities up so much. I just hope there is extension cables and a way to program multiple hups in the apps in the future
  5. HRU_Bricks
    Unification of the equipment across the different lines will be excellent. There is some missing parts at this stage, extension cables and multi hub programming in the apps, when they come out it will be good

    My plan for the 42100 is to replace the Control plus gear with all of the PU gear I have so the model is functional and then use the control plus hubs and motors on other builds.

    thanks @Courbet. Those NXT Converter cables are not too cheap.....any way around using them or that's it? It would actually be cheaper for me to buy 3 new NXT motors and use them
  8. HRU_Bricks
    @Courbet there is bsx files are they the parts file and/or can they be uploaded to bricklink?
  9. HRU_Bricks
    @Courbet Thanks for sharing the instructions! It is defiantly my next build!
  10. HRU_Bricks
    It'll probably be far cheaper in the long run... I use scuba cylinders, and they end don't last as long as you may think

    @Juroen Thanks for the link to your bricksafe page. This is the link to the latest build update video --> https://www.bricksafe.com/files/HRU_Bricks/gbc-ball-cleaning-machine-project/VID20190713203516.mp4 It needs a little bit of fine tuning but it is going well. The next section is the ball hopper box. Have a look at the the Youtube video for the compressor, itgoes over the basics and the details are on my bricksafe page --> https://www.bricksafe.com/pages/HRU_Bricks/lego-technic-auto-start-air-compressor Check out the build note PDF that should have what you need. There is rubber bands that turn the PF switch by pulling the lever which turns the motor on and when the pressure builds up there is a cylinder that turns the motor off. The pressure is controlled by the tension in the rubber bands. If you have any more questions let me know. You gauge and switch setup looks really good might have to use that idea on future builds. Here is the basic pnumo circuit of the compressor, I use a ring main approach for the pipe work on the pump cylinders so there is not a pressure build up on any one pump:

    It could be possible to make it mechanical, it would depend on the sequence. Some of the lifting and turning mechanism could be pneumatic along with pnemo-electric control.
  13. HRU_Bricks
    I too am keen to build this one and even just picked up the NXT set for practically nothing!. Defiantly would be interested in the design file or instructions
  14. HRU_Bricks
    Progress: So far so good. One key for my build is to make each section modeler so that they can be built and then installed into the frame. Currently there is a bit of hose spaghetti connecting the modules to the valves which will get sorted out closer to the end of the build. The machines overall timing is controlled by the the 5 valves driven by one L motor. The Boost hub will be used to turn the machine on and off to save power when there is a lower flow rate of balls through a GBC display.

    @Juroen I did make some changes to the ball lift including going back to a horizontal motor and 24T gear. It is running really well. As you mentioned in the other topic, there is a difference between the lift when you change direction. I didn't know Akiyuki shares photos of his builds, how do you get into contact with him also do you think you could share the pics? The next section I want to complete is the motor lift for the ball cleaning rotation (I'm sure I will modify it too
  16. HRU_Bricks
    Nice start. Are you planning on adding a duplicate pump on the other side? 16 umps may be able to supply a small machine but not sure about the ball cleaner, the large cylinders use a lot of air. 4 Pumps could just keep up with the a small control box I built for the video I did Also I have worn out 2 pumps already. When running well they can pump up to 3.5 bar. After running them for a longer period putting out 2 Bar 2 began to make a "popping" sound which was the one way value wearing out.

    @Juroen I have made some modifications to the original ball lift in the cleaning m/c and it appears to have less issues and resistance than yours. The lift is slightly lighter at the far end and added 2 gear reductions. Video: https://www.bricksafe.com/files/HRU_Bricks/gbc-ball-cleaning-machine-project/Ball Lift.mp4
  18. HRU_Bricks
    I am finding something similar with my build although it is not as prominent as your issue. When the rotation is on the upswing, the 2x 10m axles slightly rotate around the center point which then creates then creates greater friction on the 12m axles causing it to slow and require more torque. Try to slow it down some and that should make for smoother rotaton That is a lot of lift form the scissor lift. Any chance of some close ups of the mechanism

    No. Lego is working on a "dumb" battery box for use with the be motors. The reason why is to lower the price point so you can have range at a power functions price point. The cost of the controller and 4 motors is high thus lower units sold. So to be cover costs of development you need to sell more.

    Thanks for the info @Ankoku

    Do you think the vertical conveyor could be adapted easily into other builds? I need one for a couple of builds and the height of this one would work well. Are you planning on sharing the Stud.io files?
  22. HRU_Bricks
    I have started a model B backhoe of my own and now I know more about the internal structure I can crack on with it. I will be interesting as to how they go about the design.
  23. HRU_Bricks
    Who know until we get out hands on this beast! It's all fun this Lego CSI ?
  24. HRU_Bricks
    I spotted the first 2 in the boom on the very first video. In the me video you can see what looks like a third cable moving up into the boom. So is the translation that there is 2

    The Control Plus Hub is more like 2x the standard Powered UP hub with 2 out puts - 88009 that is AUD 79 each so that's 150 in controllers alone. The new L motors in the 42100 would be along the lines of 88008 medium more at 27.99 each so that is AUD 112. The large motors will be a little bit more expensive lets say 35 each so that's 105 AUD. 150+112+35=297. Now lets keep the 30 in for licencing and call the parts and licence 400. 400+297=697, then you need to add the app development costs which would be high (cheaper to develop a set then an app!). The ROI would be at least 50-100 per set (say 75). So that brings the 42100 to 772 AUD. That's my bet. I do hope you are right and not me!
