A control module with transfer to a angle encoder.
This forwards the signal to the arduino which, in turn, via a HC05 module communicates with the hovercraft
The module is made up of facets lasercut mdf sheets. I inserted this model into the fusion slicer program and then sent the files to the laser cutter.
The transfer from steering wheel to encoder is 1:2. This way, the values that you send out when you rotate the steering wheel are read in more accurately.
The whole thing also had to be properly anchored because enthusiastic children are often also very strong. That's why I increased the support surface and provided 6 threads to screw into at the top.
The connection of the Ge3D printed steering wheel to over the rod was also crucial to get the data in correctly. The rod is anchored in the round shape on the photo. This shape clicks into the steering wheel and is bolted to 4 points in the steering wheel. At the top, another top is screwed on that additionally clamps the steering rod.
The user is allowed to rotate a maximum of 180 degrees with the wheel. That's why I have a stop mechanism modeled that it is colored red here. This also provides feedback to the user when the maximums have been reached.
