Evolaco Seat 2DOF and diy peripherals

I present my 2 Dof and the construction process, I do not have many photos but I will try to explain it as well as I can.
First I will start with the electronics that I used and the motors, the engines are about 73zyt-145-12 MPC 50: 1

The electronics I used an arduino and the bridges H IBT-2, I have put an AMD CPU cooler to keep them cool, so far it has worked, everyone said they lasted little but I have not had any problems so far and the cooler It's fresh.



The stock fan was burned with a voltage rise that I will explain later
The power supply is a DPS800GB-A, it offers 82A to 12v, very good option for motion, the problem is that sometimes it was turned off due to the demand of the motors, but the biggest problem is that the motors generated votage that added to that of the source of power and reached about 20v, all 12v fans were burned at the time, I could solve everything with a small 12V 7A battery that absorbed those voltage spikes and helped the supply source to not stop, but you have to Take into account that the cables from the battery to the supply source should be as short as possible because if they are very long the supply source will be the same.


This is the box that I built for the electronics, it is made of wood and covered with carbon effect vinyl.



Although the interior is a bit disastrous with hahaha very messy cables, but did not have much space.


I have put 25A fuses of car to protect, at the moment never burned, I have also put a contactor (I do not know how to call in English) to stop the battery along with the power supply without having to carry the cables the battery until the emergency stop, this would cause the power supply to stop because the cables are very long.

I use the great SMC3 from @RufusDufus, thanks for sharing! and of sensors for the engines hall diy, the problem is that they give more degrees of rotation in one direction than in another, I do not know if it is because they only detect on one side and the sensor must be in another position, now they are like this:

The body of the sensor has been made with skate wheels, with the grinder I have rounded the core to make the support of the bearings, I have enough practice in this things and I am quite good.





Someday I have to look at the reason for the difference in the amount of money in each direction, but I am a little tired of modifying things. The sensor is connected directly to the axis of the MCP4


Now I'm going to move to the mechanical part, I never had a soldier, the welds have not been like a professional but I'm happy, the support of the engines has been safe and is 5mm and very robust, otherwise it's like any other 2 dof




For the cardan I used a BMW steering, it has a little movement of rotation but it is minimal.


Here already with the motors put to see how it was, the spring of harness shortens it to hurt more force





It's time to take it home and start the assembly


Here you can see my diy peripherals, in the end I will show you in more detail.
In these photos is all finished




I have a box with emergency stop, a potentiometer that controls motion and a switch to turn the fans on or off.


I have put software-controlled vibration under the seat and on the aluminum floor of the feet, at the feet it is less noticeable because the vibration is distributed by the cockpit, but it helps the experience



Also an air system made with drone motors, very noisy but effective, I made the casing with pvc pipe 160mm and grids with 3D printing.





I have put a harness tensioner, in the first photos it comes out longer but now I have it like that and it makes more strength, maybe I will change the springs more adelnate to make it stronger


Now I want to present my pedals, change and more things diy.
My pedals is the first thing I did diy, I used them in ps4, I had the hall sensors recognized by the T300RS, but when I bought the PC I modified the brake to work with load cell, the brake works with a small spring that acts first and then some tires that make hard pressure, the rubber bands are simple silentblock that I have made the largest hole, the clutch has a system so that the touch is real, when you step at the beginning this harder and then yields, the piece of steel of the middle causes the lever effect to change according to the position of the pedal






It also has a vibrating motor on the brake so that it vibrates when the ABS jumps or when you nail the tires, it is controlled by another arduino, the same that controls the fans.


The gearbox has an H-system and sequentially, with a part that is screwed in below it can change the mode.
All machining, like all other things, is made by hand, without having to make any part, using grinder, files and sandpaper, I am from the old Hahaha school, it has a very good and natural touch.




The hand brake works with a hall sensor, it's all homemade except for the momo knob



I also made a keypad where I keep the brake arduino and fans and the leo bodnar interface board that controls everything except the motion and the steering wheel


Finally a ring for the T300RS, I made the electronics by hand, it was the first and last I have done, it is based on the one of a t500rs, so it recognizes the steering wheel without having to connect it by USB, in the future I want to do a Direct Drive with nema42 stepper motor that a friend is doing, or buy a second-hand osw, the T300RS is already failing the calibration and more things ..


Well this is all, if you have any questions do not hesitate to ask.

Very good job, I give you my congratulations for how good everything has been.
The simulator looks very robust and the pedals, shifter and handbrake are very cool, they look very well made.

Muy buen trabajo, te doy mi enhorabuena por lo bien que te ha quedado todo.
El simulador se ve muy robusto y los pedales, el shifter y freno de mano son muy chulos, se ven muy bien hechos.

It's already done, I did not know what could be done like that

Thanks, the motion I thought I was never going to finish haha, thanks for the help friend!

Gracias, el motion pensé que nunca lo iba a acabar jaja, gracias por la ayuda amigo!

Hello, I changed my pc and I have lost my DIY license, how can I get it back?

Ok thanks, I already have the license number, but how do I add it to simtools? I don't remember how it was done.
