Here is an update on the DIY multi-function gauges I have been working on.

The main reason I wanted to do this, was to have an in car oil pressure gauge/display. I have been reading many posts of people's galley gaskets failing, and since I had already installed a 150 psi oil pressure sensor a year ago, I was already half done.

The first working prototype is done and overall it works well.
What's Good:
• Large 4.3" display
• Good resolution at 480x272
• Display has built in embedded video engine (like a GPU)
• Fast 60 frames per second graphic rendering
• Hardware anti-aliasing (give the appearance of higher resolution)
• Has capacitive (5 point!) touch screen
• Arduino Uno clone sends "light weight" commands to the LCD's embedded video engine
• My oil pressure in in spec!!

What's NOT Good:
• Viewing angle is small
• High cost ($130 in 2017)
• Creates analog noise that causes the gauge's "needle shake"
• LCD colours are not fully saturated.
• Too bulky resulting in no logical place to put it. However, it did fit nicely in the glove box, but that it too low and too far away from the driver in my opinion.

As a result, the development of this prototype has been stopped.

BUT with everything learned on the first version, we will be applying it to the second generation gauges / mini-dash.
I should have the next update in a few weeks.

Here is a short video of the first prototype:

 

Sub’d for updates.

 

Great stuff as always!!!

 

So to be clear, this works with additional sensors and not the factory/CANBUS system?

This is RAD AF! Thanks!!

 

Correct, this will work with any analog pressure or temperature sensor.

As for the CAN bus, we have about 90% of it reverse engineered and are working on something else G37 / 370z might like

 

So this could work with both CAN BUS and analog inputs?

Let’s say’s I wanted to pull EOT, ECT, and IAT values from the CAN BUS and run an EOP analog input to this device instead of an external gauge. Is that what we are looking at here? Cause if it is, I’m very much in.

 

Don't forget engine oil temperature!!... and yes, that is exactly what is in development.
A very configurable display that receives up to 8 analog inputs and can access the CAN bus.

I hope to have the next update video out before Christmas.
