Well sorta. I 3D printed this because the touchscreen experience wasn't going my way:
That's on a OnePlus Nord 100 with the Lionchief app. I tested it on my girlfriend and @G3750. She has never used a remote or made a model train move. She said she could get used to it once she remembered where the buttons were. @G3750 held similar thoughts. It would be better than a plain touchscreen. I also share this sentiment.
I have logged a few hours on it at this point and I find I'm not looking down unless I'm trying to set the throttle to the lowest possible setting. I haven't seen the button layout on for the CAB3 app but this might be a solution or the inspiration for a solution to the touchscreen debacle.
The big shortcoming is adding/changing locomotives and settings. But that's small potatoes in my opinion. We'll see how many different screens the CAB3 app includes.
I'm looking for input on what phones/tablets everyone uses for the Lionchief app. What does everyone use? I would have to measure each screen to make sure the holes match the correct areas.
Also, is there a way to turn off the locomotives from the app?
