If you’re writing in depth on a specific activity for an essay or supplement, then I would leave that out of the EC list. In particular I would try to focus on the watchmaking (unusual, you can talk about the people you made them for) and drone building (talking about your paid customers) as well as anything service related like your paid STEM counselor position, SAT tutor, or summer fast food job. You would be surprised how much of a plus a summer fast food position can be, especially if you’re able to write maturely about it.
You could merge the drone and aircraft building, or leave out the aircraft building and focus on the drone building, which is where you have more demonstrated achievement.
I would not bother writing about the crypto trading unless there’s something special about it, and it would be my first to drop off the list.
When asking your counselor to write the letter, include the Bausch and Lomb award in your brag sheet and ask the counselor to write about why they nominated you in their letter.
You speeding faster and faster on the road as a metaphor for your desire to improve would feel reckless, your drone designs getting faster and faster each iteration as a metaphor for your desire to improve would be a much better metaphor.
