I do not want to interface with any existing electronics. I would like to have the unit built and bench tested with the temp sensors. I assume voltage and hrs will not need any testing on the ski, they seems like fairly simple universal inputs that should work with any 12v system. As for RPM I need to do a little research on that but all of the of the shelf RPM gauges seem to be universal as far as engines and input goes so that should not need to be calibrated to a specific engine. I am set on a micro display preferably oled like the one I attached pictures of
as for programing buttons and menus I would just need to cycle thru menu- Temp1, temp2, rpm, hrs, volts, fuel, and have the ability to set the temp alarms maybe just use the oled display as a flasher and eliminate any external leds
I am interested in doing this project with the hopes of being able to reproduce them myself once everything is figured out by copying and pasting programming coding, building the housings, soldering up the wiring and waterproof plugs. I really just need a functional bench prototype to duplicate. Im not planning on any commercial marketing of them but I would like to post them on the freestyle ski forum and be able to reproduce them as needed, there is not a big market for this type of item but I do think I will be able to sell some of them to fellow riders. I understand the first one might run into some money but if I can reproduce them later for under $250 in hardware and sensors it would be worth it. Almost all freestyle skis are two cylinder 2 strokes with no electronics.
I will have to figure out what fittings I will need with sensors but hoping that I can find temp sensors with different fittings or end types that work on the same ohm loop for other builds
I was thinking something like this -
I attached a few pics of the store bought motorcycle units display but it doesn't have any warnings, I plan on machining aluminum waterproof housings for the oled displays

I can email pics of that would help my personal email- email@example.com
