Lmp1 Style Wheel

A WORD OF CAUTION

"Issues relating to the effects on health and well-being of artificial light are discussed in three recent publications; including one that says the blue-light component in white LEDs causes toxic stress to the retina." "...optical radiation detected by the retina impacts an individual’s behavior, psychology, and perception of the environment."

What is being said here is that the LED light on the eye retina is bad for health! The LEDs on this wheel are so intense, as they are configured, that sickness can be felt after the first minute.

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.

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.

TM1638 DONE

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.
