    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.

    Great to see all of your experimentation and innovative ideas :thumbs

    Do you have a link to vibration speakers you are using?

    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 IMG_20201218_131137.jpg

    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.

    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 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

    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"
    IMG_20210102_151227.jpg IMG_20210102_151540.jpg IMG_20210102_151627.jpg IMG_20210102_152007.jpg IMG_20210102_151627.jpg IMG_20210102_152007.jpg
    The next step is to take the "Top frame.STL ”, four M6x90 bolts and 12 nuts. Assemble as shown in the picture
    IMG_20210102_153053.jpg IMG_20210102_153336.jpg IMG_20210102_153359.jpg
    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)
    IMG_20210102_154737.jpg IMG_20210102_154921.jpg IMG_20210102_154849.jpg IMG_20210102_154420.jpg IMG_20210102_192335.jpg IMG_20210102_192605.jpg
    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
    IMG_20210102_152052 pin.jpg IMG_20210102_205635.jpg IMG_20210102_223620.jpg IMG_20210102_223610.jpg
    The resulting part with microswitches is pushed onto the bolts at a distance of about 45 mm and fastened with M6 nuts
    IMG_20210102_224353.jpg IMG_20210102_224422.jpg
    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
    IMG_20210102_154059.jpg IMG_20210102_224537.jpg
    Connect micro switches to arduino Leonardo according to the pictures below
    2DOF_8.png 2DOF_9.png IMG_20210102_231713.jpg
    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)
    IMG_20210102_160728.jpg IMG_20210102_160707.jpg IMG_20210102_195244.jpg IMG_20210102_234937.jpg IMG_20210102_235043.jpg IMG_20210103_000235.jpg IMG_20210103_000259.jpg 2DOF_10.png
    Handle position for first gear (left and forward)
    IMG_20210102_234709.jpg
    And this is how it looks inside
    IMG_20210102_234722.jpg
    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
    IMG_20210102_234626.jpg IMG_20210102_234650.jpg
    Happy assembly to all! I went to collect the handbrake
