I have nowhere near the skills to make these work, but if others do, my first idea is

 

1) a handheld, wireless wifi throttle based on one of these.

 

 

or for those of us with fat senior fingers

 

 

 Designed as a secondary throttle for walk around use, just the size of the dial.  Using the outside rotating section as the speed control.  There is a touchscreen on it that could be used for basic functions, or whatever your fat fingers could click on.  They are complete esp32 units, except for an attached battery.  I think everything is included in it that we would need- the control, the display and wifi.

 

 

 

It should be easy to 3d print a battery that goes on the bottom, hopefully seamlessly to add lithium batteries.

 

I would love to be able to pick it up, put it in the palm of my hand, then walk around endlessly fixing my layout....

 

It would also, I think, make a fine commercial product

 

Volunteers?
