I don’t know why, but there are few things I enjoy more than living vicariously through people who document raspberry pi projects and use cases.
The end result clearly looks amazing. I'd really like to get into doing that, but every time I try, it ends up being way tougher than it looks and the net result is nowhere near as clean as it is in the pictures.
You're looking at the 10th, 20th, 30th+ attempt being documented/curated on the internet. You've gotta break a few eggs to make an omelet, so don't let that not-so-perfect first try slow you down if you derive value from tinkering.
Much like writing code, you collect knowledge along the way and the next one is hopefully better.
