To the original post: give it a try. Things take time. If you enjoy the process more than the result, its 100% worth diving into anything. Even if you don't finish it, you might have fun working and learning. I built an entire game 100% from scratch with 0 off the shelf parts / electronics. Massive timesink of endless nights for a couple years. Depends what your goal is? Pinball designer? DIY-er? Or you just don't want to drop $8000 on Baby Yoda?
