my simulator

Hello, my name is Juan, I am Spanish and I live in Madrid,
I have just finished my simulator thanks to the infinite help that you provide through your forums.
My simulator is a very small and simple version, the room where I install it leaves me no other alternative but at the moment it works with Live For Speed, although my intention is that it works with Prepar3D, since I am a great fan of flight simulation since many years
I want to show you the steps that I have followed for the construction and the materials and the tricks that I have had to invent to overcome all the obstacles that were presented to me on a mechanical and electrical level.

A sample of the finish of the Arduino circuit

As you can see the simulator I initially thought to install it in the structure of an office seat, I liked the idea, but once it was finished I discovered that the seat was too high and I could not reduce that distance from the ground so I had to change my mind and conceive a structure independent of the seat.

Basically the system consists of two wiper motors, a very robust cardan shaft, linear plastic potentiometers and quite rudimentary levers.

In this other image you can see how the potentiometers engage the motor shaft in a simple and practical way

My first serious problem was the short length of the motor shaft that I had to solve by gluing two washers to the lever and also deforming it so that it did not collide with the screws of the motor support

I had to reinforce the anchors of the system due to its extreme weakness, duplicating supports and joint joints to give it some flexibility.
Also I have installed some movable supports to rest the mechanical system when I do not use it.

here are some short videos of my first tests with the 2dof

another one but still without load ...

and the first one with a load! I apologize, in the sound my daughter's bath was placed bathing the dog ..

You may have noticed that the movements are very short at the moment, because I am starting to adjust the sensations that it transmits to the seat.
This is the configuration of the 4 axis roll, pitch, surge and sawy
Roll and appears I have them set to 20% smoothness

The explanation of this 20% smoothness is for two reasons, set to 0%, the movements are extremely abrupt and the consumption of the motors shoots up logarithmically.
This also occurs in any of the axes, but it is more noticeable in the lateral movements, surely due to the physical arrangement of the levers so close to the Cardan.

THESE THREE POINTS are weak in my construction and I must improve them, I will have you informed when I have solved them, regards!

Sorry for my long absence.
Thanks noobeast for you recomends,
I have already made some modifications to the simulator that have greatly improved its performance.
These are the main improvements:

As you can see, the solution is the most widespread and reliable both in the union of the levers and in the control of the motors with the new sensors hall free of rotation and 360 degrees

the simulator with these improvements already works better, but I am finding a problem with the control of the motors
These make an "eletric noise" in each movement, it is a noise like a squeak, as if the electric currents that pass through the brushes were not in consonance or something similar.
