• Evolving to 3.0 with Lego Mindstorm

  Bas van lieshout • 09/15/2021 at 18:56 • 0 comments

  Got hold of a Lego Mindstorm set for €60 and decided to do a rebuild. When testing with the old unit which holds 3 records I’ve noticed that the Ultrasonic effect (ripples on watersurface) is disappearing when loading 3 records. When loading 2 records I also notice the effect is less. So decided to go for a single record option and here you go. Very simple and effective build and 100% Lego this time. Spinning is now programmable which opens lots of new options like a start and stop spinning program where the record sits still in the water for optimal cleaning. Let me know if you are interested in more pics etc.

• Evolving along the way

  Added a second row of 3d printer wheels to stop the wobbling.

  

  Added lights and different wheels for the motorized part.

  

  First testdrive with the new parts. All goes well, even with fluid added. As you can see with 1rpm there isn’t enough water sticking to the surface of the record for the label to get wet. And this is tapwater without any additives.

  

  Overview of the upgraded parts.
