Awesome! The finger pain goes away pretty quickly if you keep playing. They get soft again if you quit. At some point, a callous may start to separate on the edge. Don’t pull it! Resist the temptation! Under the callous is soft, wimpy skin. Lol

I got interested in guitar when I was a little fella. My pap had an acoustic leaning in the corner. I would think of a melody and move my fingers around until it sounded like what was in my head. It was a painful process for everyone around me!

You can play thousands of songs with 3 chords. Pick three chords and practice switching between them until it’s second nature. Then you can mess around with rhythm, timing, and finger picking. Some of the greatest songs we never heard were written on back porches all over the world. Have fun!

I am not an engineer, but think the wind would work against the windmill in that position. If you fabricated a ring bigger than the blade-span of the windmill and drop the center of the windmill just above the “event horizon”… the wind would hit the face of the blades better.

I see where you may be getting this idea. Some birds float on the wind swells that shoot up mountain faces. If you could create a difference in air temp between the top and bottom of your plastic pyramid, it may create a draw on the wind.

Just my 2 cents. This is fun! Your son is a thinker. Need more of those in the world!
