Sequential shifter for sim racing

Last crawled date: 4 years, 2 months ago

This is a sequential shifter for driving simulators. The shift feeling is imitated by two bearings following a track, preloaded with a spring. I think the bearing track come out really good, this is the kind of shifting feel that I wanted to achieve when I started this project.
In the video you can see how it works:https://photos.app.goo.gl/fvwjAALshejXzDWe9
The bearing size is 15104, like these ones:https://www.ebay.com/itm/10-PCS-6700ZZ-10mm-x-15mm-x-4mm-Modle-Sealed-Metal-Shielded-Ball-Bearing/142522930988?hash=item212f07572c:g:X5MAAOSwb-Jcdjgk
For the spring you can use any kind, I also attached a printable one if you can't find a proper spring.
For the microswitches, I use these type:https://www.ebay.com/itm/20Pcs-KW10-125V-1A-3-Terminals-Momentary-13mm-Lever-Arm-Micro-Switch-xh/223740877425?hash=item3417feda71:g:K8YAAOSwBLdZs4zu
Currently they are attached to the shifter with toothpicks, but it should be attached by M2 screws.
Required hardware:
10pc M4x10-20
1pc M6x40
1pc M6 threaded rod, around 140 mm long, it depends how long throw you want, and how long is the spring you use.
4 pc M6 nuts
I think the assembly is straightforward from the pictures.
For smooth movement, cut a plastic straw piece, and place it between the slider and the threaded rod.
Electronics wise use whatever you like, you can use an arduino board, teensy, leo bodnar boards, etc.
