Ran across this while looking at ELS options.
Looks well put together.

I'm still watching the presentation, but first impression it's a little pricey for what you get in comparison to others.
I like that he has attempted to have both metric and imperial capabilities and also tried to add BA threading capability.
However, he made some coding choices to minimize the complexity of the input and interface and maximize data input speed using buttons only that compromise the usability and functionality.
The choice of how to implement different systems presents two paths, selecting two different modes and two separate coding paths, or selecting one base mode and then using conversions. This developer selected metric and then opts to convert to imperial mathematically. Then he also added British Association at a user's request.
One other factor he landed on was to limit the choice of the minimum measurement input increment to 0.05mm. This means that any calculated imperial or BA thread that is not divisible by 0.05mm cannot be cut. For example BA 14 pitch is 23 mm so the correct pitch cannot be calculated.
This particular type of issue is why my buddy and I selected an encoder wheel input to allow expedient data input at a much much finer granularity so that compromises in available threads do not have to be made. A primary reason for a electronic gear box is to resolve issues of mechanical gearboxes not being able to cut desired threads.
I just do not understand the logic of such choices and compromises. Unless the person doesn't know how to code for using encoder for data input
