For the past two months I have been learning LUA and coding a Garmin G3X CDU460 touch screen display instrument. At this point the engine related pages are mostly complete and my next work will focus on the navigation pages. However, at the pace I am moving (there are many more months of work) I'm beginning to wonder how this effort can be monetized. .
Progress to date can be seen at https://www.youtube.com/watch?v=B5PXBL6Ym_E&t=13s, or on my Youtube Chanel: kjb2401
