Has anybody got experience/recommendations for using any of the 4" or
3.5" TFT touch screens on an RPI and operating it outdoors?I ask because I'm wondering about replacing the Medion S3747 PNA, which has a 3.5" screen with a similar sized package based on an RPi fitted with one of the TFT touch screen HAT units as the navigation display in my glider.
The RPi would run the Linux version of LK8000 and replace the Medion, which runs a WinCE version of LK8000, as the moving map navigation system in my glider. Since the glider has an untinted bubble canopy the performance of the screen in bright sunlight is important: the Medion hs very good in this respect because it has a trans-reflective screen which is readable, even with direct sum from over my shoulder on its screen.
I have a space problem on my instrument panel: a 3.5" display is OK and so is a 4" display provided its bezel adds less than 3mm to the width and height of the display - some of the newer displays look as if they can be housed in a custom enclosure that meets this requirement. Thickness doesn't look to be an issue because a Pi B wearing the TFT display hat isn't much thicker than the Medion. LK8000: is an open source community developed glider navigation system.
It has been compiled to run on a RaspberryPi - I'd probably put it on an RPi 2B because that should be fast enough and having an ethernet connection is nice for uploading plottable NOTAMS, restricted airspace maps etc.
