Building a Raspberry Pi data output screen.

[sarabande]

I have archaic and rusty programming skills, and too many things going on to learn a new language.

I want to build a (waterproof-ish) data output screen to contain the following

Time (hh:mm:ss)
Date (dd:mmyy)
Stopwatch (Count down and count up)
Temp of engine coolant inlet (i.e. sea temp)
Temp of engine coolant outlet to silencer
Air pressure (to a decimal of a hectopascal) plus a graph
Air temp ( ditto)
Rel Humidity
Wake up alarm
Associated warnings at variable dB.


All with a high degree of resilience.

I've looked at various sites, and wonder if this is the sort of project that a competent 6th former or Yr1 electronics undergraduate might wish to set up in return for some £s. Any thoughts please ?

I've done similar with a remote display taking data from a raspberry pi then using another tiny board - esp8266 - to display the data. Shouldn't be too hard to get a waterproof display though power in and the buttons might need some thinking. Haven't been sailing much so the project hasn't progressed other than see it working. Plus is the Pi stays in the warm and dry down below then all data is over wifi. Pi is pretty easy to set up initially, no real sleeves up programming needed, all through node-red which is mostly graphical then there's some software for the esp which makes setting it up easy on a web age as well.
Shouldn't need a monitor for the Pi, any tablet/laptop etc can be used to see all the data over wifi, some tasty signalk apps now as well.

Take a look at the Node-RED visual "flow" programming language - mostly drag-n-drop and great for producing "dashboard" type displays: https://nodered.org

I also build something similar. I'm really far from being a real or good programmer but my little piece of code took me just a few hours. Maybe it's motivational for you to start with python and build your project at 1 or 2 weekends.
Here is my code:

and a little video (without date and time):

All this is most encouraging. Links and video libraries which I never knew existed. Off to do some reading and watching.

Thanks

you really can do lots of stuff with all that (and VERY CHEAP!!!)
not a programmer by any stretch of imagination, it's dead easy though and done quite a few to prove it!

What is NOT easy is finding any IPa_lot TOUCH screen at arduino prices, not talking 3-4 hundred euro.
And what is even more difficult is find something with half decent refresh rate (was planning to do some graphics there)...

I really need one for my f/b and I'm seriously stuck

cheers
