boat lcd/touchscreen: sunlight readable, watertight, touchscreen
I ran vga and usb cables down to a laptop in the cabin, wired the screen power into the 12v system, and temporarily mounted the monitor in the helm for a proof of concept until I get the final encosure finished. All seemed to work well. No for a real open water test- I took the boat from Carolina Beach NC to Charleston SC over labor day weekend. The transreflective screen did great in direct sunlight- It wasn't super bright, but it was definitely readable and functional in direct sunlight. Brighter would have been prettier, but its not like you had to cup your hands over the screen or anything to see it. I had backup paper charts but the nav/gps system helped me stay out of trouble for the entire 150 miles down the waterway. No pic updates, but the interface you see below is what I used. As soon as I get the enclosure finished (this week?) I'll post some pics.
So the title says it all. Its a tall order to be sure, but i'm sure its doable. There are some great marine grade screens out there, but it seems to get an industrial strength watertight hibright screen (never mind a touchscreen) you just have to be prepared to spend the cash. -Like anywhere from 2 to 6 grand.
Updated- pics of the nav software added below ...
I have a 34" cruisers express with an open cockpit (see pic below), and plenty of waterproof storage for the actual computer. So the lcd is my main problem for now. Here is what I was thinking:
- Buy a transreflective, sunlight readable 7" touchscreen from the store here when they get back in stock.
- Build a watertight bezel using abs plastic, silicone seals, and a thin clear film covering to allow pressure to go through to the touchscreen, but sealed along the edges of the bezel to make it watertight.
- possibly add a fan in the back for ventalation.
Any thoughts on this?
Am I missing something about the way the resistive touchscreen works?
Here is a pic of the helm area- On the left is the current (outdated) gps system and the mount point for a new flush lcd. (I hope)
You can get a better idea from the pic of the flat surface I have to work with - Very much like a car dashboard but with more room. :) I actually have room on that spot for a 10.4 inch screen but I need the sunlight readable make this work so I'm sticking with the 7" widescreen.
