CarComputer | The onboard computer for old cars

Is a CarComputer a onboard computer? If you ask Wikipedia, it says:

A Car-PC or Carputer is a computer that is permanently installed in a car or truck, usually with a touchscreen for easy control.

According to me, a CarComputer is a replacement for a missing onboard computer. It consists of a small screen with a computing unit (in my case, a Raspberry Pi).

What should the “onboard computer” be able to do?

The plan is to display various temperatures, such as coolant, oil, interior, and exterior temperature. In addition, it should display the battery voltage, and if possible, also include a lamp monitoring system 😀

I recently came across an open-source operating system that I will try out. The OS is called Crankshaft and provides an Android Auto solution for Raspberry Pi. Let’s see if the software is also suitable for querying i2c sensors. If you want to learn more about it, here is the link to the product page.
