Due to really lack of time, rush out this simple motorized scissor
first, i cut out a L shaped holder from old table calendar cardboard. it is hard enough and easier to work with
After that, i glue the scissor to the L-shape holder. well i could have attached it with screw, but...to save time, glue is useful
And this is the video that it is in operation. i do find that it needs at least 5V to operate properly. At 3V, it cannot move
From the power supply, we can also see that it needs 0.3A with load (compared to 0.1A during my testing load free)
was originally thinking to put the magnetic sensor to detect the position of the scissor (either open or close) but let me do that last minute now it is to do system integration
putting everything together.
decided to use load sensor to sense grass

That's brilliant! I cannot ever remember hearing that you have to have elegance to be more effectiveness. Keeping it simple works for me....
This is a really neat solution, suitably bookmarked so I can find it in the future.
I turned the volume up to see if I could hear anyone in your kitchen asking where the scissors were
