On this episode of Motorvate's DIY garage, we are going to show our first try at making a:
Digital, DIY engine oil pressure and fuel pressure gauge.
** This is only a development prototype, as old parts were used that are no longer available. The next version is under development now.**
There are two reasons why this was developed:
• Verify if a low cost, easy to assemble mini "digital dash" is possible and functions well.
• Verify the oil pressure on my G37 ( I'm worried about failing gaskets!)
We used a $15 Elegoo Uno (Arduino Uno clone), a $10 Arduino Uno style "terminal shield" and a $130 Newhaven Display Shield we had from another project from 2017. (In the Arduino system, the word "shield" means it simply connects like lego... no wires or soldering to worry about!)
The display we used is no longer available, but since we already had it, we put it to good use. (Specs: 480x272 TFT, Capacitive touch screen with an embedded video engine (EVE) that does all the graphic rendering @ 60 Hz)
As for assembly, all the circuit boards simply stack and connect to each other.
This is our "working first prototype". It is large and ugly, BUT it works well even with a few technical issues. (Analog noise resulting in "needle shake")
No source code will be released, as it only works on the old FT800 EVEs. (embedded video engine)
However, the second generation is under development right now and we do hope to release a "lego like" DIY kit so anyone can assemble regardless of electronics skills.
This should be fun!
