A WORD OF CAUTION
Keep this in mind when using yours too bright.
On to The wheel
The rim is a Sparco P104 replica;
The box on top of the wheel is a rectangular plastic (ABS) one.
The board that holds the little multicolored buttons the display and the leds its a generic board that holds a Tm1638 chip.
The Leds on the 1638 board are 5mm, 3.2V, Pink. It´s an arduino Nano to connect all this apparatus.
There´s a singular push button on the wheel and it´s a NKK MB2011 with a GB13B guard.
The board inside the BOX
I desoldered the default leds and buttons. It was then used the 5mm pink leds and longer push buttons. With longer push buttons i could fit the colored caps (photo above).
You can connect this board to the arduino nano as exemplified below.
I use this wheel on one of my G27´s and it works fine. Can´t show a picture because i have none.
You can make different arrangements with the DX SLI Manager software regarding the displays and Leds configuration.Converging shift lights is an example
On closing...
This was a quick made project. It came as a solution for a display on the wheel and it turned out just fine, with room for the full degree of rotation of the wheel, 900º.As this was a project that was almost all built in my garage, extreme attention to tolerances in measurements on the cutting of the box was not taken into account.
A reminder is that it can be used in other wheels because the software runs independent of the wheel.
See you soon on the next project.
Have a nice day!
