2dof (plywood and aluminum profile construction)

Vibro dynamics are much cheaper than bass shaker so I decided to try using them. I bought 2 pieces and started experimenting. First fixed on a movable plywood platform. As a result, I received very little vibration on the chair. Now I will try to attach it directly to the fiberglass chair.

Here is a link to vibro dynamics

I fixed 2 vibro dynamics on the chair itself. Feelings have changed dramatically for the better. The vibration goes directly to the human body, the rest of the installation does not vibrate. The vibration from the motor is gentle and accurately conveys the operation of the motor. It can be used to change gears blindly. Now, in moments when the installation does not move (for example, driving on a flat surface), you still feel the engine work. Vibro dynamics, in addition to vibration, also emit a hum (roar) of the motor, which is very cool. They can be connected without software. You need to output sound on them through a low-pass filter and an amplifier

During operation, the vibrodynamics get very hot (impossible to touch). I had to install airflow on each vibro-speaker. Two fans blow through the holes in the plywood to the vibrodynamics. Now it is good. After prolonged play they are warm but not hot.

The work of one vibrodynamic speaker attached to the bottom of the chair. The sound is muted everywhere. Gas powered engine operation.

Presentation for friends

looking great good job I would add maybe 10% heave just to get the bumps feels great in rally games

I want to make a gearbox like this. I just want to add a reverse gear so that the lever is recessed. That is, the reverse gear was engaged as the first, but at the same time you need to push the lever down and start in the same direction as the first gear. There will be a 6 + 1 gearbox. Maybe someone has done something like this before?

I screwed the aluminum profile bar. The bar will be equipped with a tablet holder for the dashboard

I like the underglow you have. I did the same with my sim haha.

I'm very glad that my posts help you

Dashboard

And here is the video with the dashboard

I bought components for the gearbox. Now I am designing and finalizing the existing structure.

Made a gearbox (six speeds + rear). If necessary, I can post STL files for printing, accessories and scetch for arduino

Tomorrow I'll take off the gearbox in action game. In the meantime, this video

Video of the gearbox in action

I will tell you how I assembled the gearbox. Below I will post an archive with files for printing and firmware for arduino. So let's get started! You need to take two 625 (5x16x5) bearings, two M5x15 screws, four M5 nuts and the "Center block.STL" printed part. Insert two nuts inside the "Center block.STL" , screw the rest of the nuts onto the screws and tighten with the bearings as shown in the figure. The main thing is that the screws do not stick out in the central hole of the "Center block.STL"

The next step is to take the "Top frame.STL ”, four M6x90 bolts and 12 nuts. Assemble as shown in the picture

We are assembling the center piece. Take part "Staple.STL" and insert two bearings 688 (8x16x5) into it, fasten with two screws M8x20, nuts M8 and sleeves "Sleeve.STL". The "Staple. STL" part must rotate freely without jamming. Then use the M8x16 screw to attach the PHS8 pivot pin (bought from AliExpress)

We print on the printer “Stencil.STL” and “Reverse_gear.STL”. Take 7 microswitches (20mm) and use screws M2.5 we fix them as shown below and you can already attach the wires

The resulting part with microswitches is pushed onto the bolts at a distance of about 45 mm and fastened with M6 nuts

Take a 165mm M8 stud and tighten the two nuts, opposite each other. Then we screw onto the tip “Tip.Stl ". From below we insert a pin through the" Lower ring.STL", pivot pin PHS8 and from above we press the assembled central block. Then the washer, spring, washer, nut M8 and tighten the last with the handle “handle

Take the arduino Leonardo board and fix it with two M3x8 screws

Connect micro switches to arduino Leonardo according to the pictures below

Print the bottom “Bottom.STL ", cut a 100 mm long ventilation pipe with a diameter of 125 mm, take two long bolts (I have M8x140) and finally assemble and fix the gearbox. Do not forget to run the microUSB cable. Below is the firmware for arduino Leonardno. Arduino is defined in the computer as a game joystick . Button 1 - reverse, button 2 - 1st gear, button 3 - 2nd gear, button 4 - 3rd gear, button 5 - 4th gear, button 6 - 5th gear, button 7 - 6th gear. Button 8 is the handbrake. I have a cable with two wires (GND and pin 10) for the future (you can skip it if you don't need a handbrake)

Handle position for first gear (left and forward)

And this is how it looks inside

Reverse is switched on as the first, only you need to drown the handle (to the left, press and forward) in the photo, respectively, the view from above and from the inside

Happy assembly to all! I went to collect the handbrake
