My grandfather, a NASA engineer who worked on telecommunications systems for many of the Apollo missions was always coming up with things I never saw anyone else doing. Some of that came from having engineering education and skills, but much of it came from a willingness to learn new things — he was never intimidated to do something new.
He loved telling the story of his father wanting to keep squirrels off his grape vines, so he
ran electrical wire through the trellis the vines were on, and put a button by his back door. When he pressed the button, it would give the squirrels a zap and they didn’t come back to try new grapes. (Apparently you could tell which squirrels were new to the neighborhood, because each squirrel tried to eat his grapes exactly once.)
When my father was in college, his 1960’s VW Beetle was having significant engine
problems. My grandfather didn’t want my dad worrying about the car when he should be focused on school, so my grandfather bought a mechanic’s book on the VW bug and over a weekend he rebuilt the entire engine in his garage and brought it back to my dad. I heard this story while helping my grandfather adjust the spark plug timing on an old 1970’s Plymouth in his driveway — it was a fun afternoon learning how engines run.
My grandfather came over to our house when I was a kid to help us hang a bird feeder in our backyard. Instead of some more boring options, he came over with a bow and arrow (pretty cool way to show up at your son’s house), fired an arrow over a tall branch with a rope attached, and used the line to hang the birdfeeder with an anti-squirrel dome over it, far enough from the tree that the squirrels couldn’t jump from the ground, tree, or branch to get to the food. We had that birdfeeder for at least 15 years, and a squirrel never managed to get on it.
My grandfather installed counterbalancing weights on strings and pulleys for all his sliding screen and glass doors, so you could open and close them with a tiny touch — it wasn’t necessary, but it was a constant touch reminder that with a little effort, creativity, and patience, you can do some cool stuff (and this was long before you could Google, YouTube, or Quora search something).
