Maker and hacker Greg Matthews has ingeniously utilized a Raspberry Pi display and Pi mini PC to create an impressive touchscreen in-car digital dashboard. This innovative setup provides real-time data on various essential metrics while driving, including speed, RPM, and engine temperature. This project not only enhances the driving experience but also offers a cost-effective solution for car enthusiasts looking to modernize their vehicles.
Project Overview and Features
The digital dashboard project leverages the power of Node.js and the car’s battery to operate the system efficiently. Remarkably, the entire setup has been constructed for under $170, making it an affordable yet highly functional upgrade for older vehicles. The dashboard is designed to be compatible with pre-OBDII Nissan cars that have a consult port, such as the Nissan 240sx s14 and s13 models.
In the video below, Greg Matthews provides a detailed walkthrough of the project, demonstrating how to install the necessary software and physically integrate the dashboard into the car. The current version of the dashboard displays live data on speed, RPM, and coolant temperature. However, Greg has plans to expand its functionality further by adding features such as check engine codes and the ability to clear them. This flexibility allows users to customize the dashboard according to their specific needs and preferences.
In this video I show how to make a digital dashboard for a pre-OBDII Nissan car with a consult port. I show how to install the software and install the dash in my Nissan 240sx s14; this will work for an s13 as well if it has a consult port. The dash runs on a Raspberry Pi 3 and shows live speed, RPM, and coolant temp right now. Later I want to add check engine codes and the ability to clear them. If you want to suggest features, feel free to comment below! Also, let me know if you do this project yourself!
Expanding the Project
For those interested in further enhancing their Raspberry Pi projects, there are numerous additional components and accessories available. For instance, integrating GPS modules can provide real-time navigation and location tracking, while adding Bluetooth connectivity can enable hands-free calling and music streaming. Moreover, incorporating sensors such as accelerometers and gyroscopes can offer advanced vehicle diagnostics and performance monitoring.
