Rat Project Logitech G27

Welcome back. I hope you’re having a good week!

This project was based on a Rat approach and for that i used  one of my G27´s. The objective was to use parts i already owned.

Being so, i had a 5″ LCD, a Shift Light Indicator (SLI-M), 10mm Led´s, push buttons and the cover of a box (front cover of Button Box V1).

I will start right now: This may impact some viewers…

Top plastic cut off and front grill* removed. (* bottom of page)

Next: The top part at the shop to clear some edges.

The usual nécessaire for soldering!

After soldering the buttons i need to try them to check connections and cable length.

The first idea was to have 8 push buttons and 1 (5 mm) LED  in the center to light up when “pit limiter” was ON.

But i have to remember the reader: The SLI-M is the one controlling all the push buttons and LEDs. All the other parts are dependent from where this unit is placed. This SLI-M has the ability to plug up to 16 push buttons and 5 extra LEDs.

I decided to use 2, 10mm LEDs, 1 Red and 1 Blue to signalize different options, and ditched the 1 centered 5mm LED.

The Blue one would light up when “pit limiter” is ON. The Red one when vehicle is damaged. I have assigned the buttons below the Leds to functions related with pit entry, exit and vehicle damage although they can be used to other functions.

I used the outer case of two push buttons to make the case for the LEDs.

The LEDs would fit perfectly.

Advice:

  • It is advisable to have jumper wires to connect components to this board. Male to female or female to female. You choose witch fits best. They are not expensive.

Used material until now:

  • 12 mm push buttons,
  • 1 Shift Light Indicator,
  • 10 mm LEDs

The LCD

This LCD is a  5 inch HDMI with a resolution of 800 x 480 and resistive touchscreen.
A Raspberry Pi 2 can be connected directly to this LCD but it can also be used as a 2nd or 3rd monitor via HDMI. In this case i am using a HDMI to mini DisplayPort Cable and a mini usb to power it on.

The black outer case is made of acrylic and can be found online.

The Software being run;

I tested some available software; below is IRDDU 2.

Z1 Software below;

All software runs as expected fitting the monitor well, with some minor adjustments to one or the other.

My singular choice is the Z1 Dashboard Software. I have been testing IRDDU 2 with this LCD but Z1 has been given attention, detail and work for it to run as it does.

Running with the shift light indicator (SLI-M), controlling the LEDs and push buttons was Fanaleds.

This is the front panel on the  Logitech G27 and it is similar to the front of the Shelby Cobra Gt500 2013, almost exactly. img_20161010_181947

Before this Project;

img_20161003_153037

The temperatures in the country i live in get really high and this summer i noticed that during a 2h race the wheel was not responding as it “should”. The plastic above the motors was really hot, so… .

img_20161003_153050

Unused fan and an old Nokia charger, stripped the wires, solder them and i have a fan to plug into the wall socket.

Well, it was not a scientific test but it made the plastic a lot cooler.
