Good evening , so here I am . All new and fresh 
colorblind mechanic , so perfect to launch myself into electronics .
Me and my son are currently building a junior Dragster with jet turbine.
To light up the afterburner we are using a Arduino Nano to control a ignitor plug.
For the rest I bought a EGT Display of Amazon , pure crap.
So now we decided to launch a new Project.
Our idea is to put a Display into the dash or Steeringwheel.
On the power up we wanna put a custom text or maybe even our Logo onto the display .
After a couple of seconds we wanna put a 2 line setup on the display , upper line EGT with a K style termocouple, on the lower line Oiltemperature to be displayed . If possible we wanna put an alarm for max EGT and max Oil temp into the code , to make the display blink for example or control an exterior Led light to warn him .
So first question is to get the right hardware together. Either Nano or Uno , what kind of display is suitable for some stuff like this?
Thanks in advance
Sam
I've been using a 4 line by 20 character monochrome LCD to display 8 parameters in a GPS based speed, altitude, heading, sattellite data, date and time system.
Use a paper lined up with lines and columns and put Your need to it. A text telling the parameter name and the space needed for the measurement. Check how much space you need!
Find sensors that can measure the physics You want. I guess a standard UNO can do it. For more slim builds there are controllers occuping less space. Sum upp which sensors You will use.
Look for sensors having datasheets! That will help both You and us.
Thanks a lot , will check for the sensors tomorrow , 2 channels will be enough for me .
Good looking project, but I don’t understand this line…
? Not clear what that will contain.
On the powerup of the car / display I wanna see a “greeting message” first . Let s say : Weyland & Sons Jet Dragster for example , after that being displayed for 2-3 seconds I wanna switch to the “main display” with the 2 channels being displayed , EGT on the top line and oil temp on the bottom line .
Lovely ! Thats what I am looking for !
I am currently checking on the sensors . Unfortunately most sensors on Amazon do not have any infos regarding the values . They only show a max temp . But not the values regarding the sensor. So impossible to write a code when you dont have the infos needed
Display in the steeringwheel sounds good, but will it look good? 
Consider vibrations that both the dashboard and the head can experience, which could render the visibility of the display bad. Something you might wanna look into is the new round OLED displays that can be laid out as an analog meter, could be easier to read.
You are right , but the display is only to be used prior and after the run . So vibration should not be an issue . But I still will check the new OLED Displays
So this is what i have in my Amazon Basket right now . Unfortunately I dont find any data about the values of the sensors , only the temp range it operates . EGT 0- 1250 Celsius and oil Temp 0-600 Celsius .
What do you guys think so far ?
Furthermore I question myself if I should connect the arduino with the MAX and the display via soldered wire and put it in a 3D printed case or if their is a more elegant way to do it ?
That is what aircraft manufacturers said with the first surface mount devices. The problem only occurs the next time you want to use the device!
You mean the LCD could be destroyed due to the vibrations ?
My idea was a 3D printed case mounted with some rubber or nylon dampener behind .
I am an aircraft technician for 25 years , i know the problem of vibrations , but very new to electronics , so I have no clue on how tough those displays are
They are not called Liquid Crystal Displays because they are solid state.
Ok i have to admit you got a point on that
So what would be the best option for this application ?
So i guess Oled is the way to go , i will try to find more infos regarding the coding of free text etc on this type of screen
At €43 it's more than if you get something from China, but these displays (Mouser got many more, this is just something that popped up first) got proper datasheets, and with tests, one be vibrations..
Actually just got in mind another usefull function I wanna add , since we are running in battery power without alternator it would be nice to have a voltmeter as well .
So it is getting more complicated .
Maybe a smaller display ( Oled ) which i could switch over from EGT to Temp and Volt by pushing a button .
Still monitoring all parameters and triggering an Alarm , for example flashing display or external LED warning light would be an option .
One thing I really don t get. I was searching for Oled screens to suit my projects . Some Oled screens are marked LCD , am I wrong assuming Oled is the principale the screen works ? Is it a brand or a type of screen ?
Also some screens are marked TFT which to my knowledge are a type of LCD as well
I m really lost on that for the moment
