I guess the stats speak for themselves, but I'd at least like to offer some anecdotal encouragement of sorts. Just so you know there are those if us that LOVE your design/instructional videos.
There are two specific videos that have been pivotal for me as a hobbyist. I came into the hobby designing vacuum tube guitar amps. This requires a decent fundementals knowledge to get good results, but it is a pretty niche part of electronics, and it left the vast majority of the field a mystery to me. An intimidating mystery to be exact.
So I stumbled onto the "Hack a vacuum fluorescent display" video. Mind you, up till now, digital was considered completely out of my reach by me. I'd just convinced myself it was something I'd never understand. But here was this guy making it look easy, yet not dumbed down. Long story short, within weeks I was doing good projects with microcontrollers. That video was the catalyst to a whole new world for me.
The other video I want to cite as a specific source of inspiration is actually a video series. The "design a bench power supply" series is the EEVBlog at its best. One of the difficulties of a hobbyist is having learned all these building blocks circuits, but not really knowing how to build a quality product. That series completely took the mystery out of building a pro quality project as opposed to just "something that works".
I realize you can't cater to the minority and be as successful as you have been, so I mostly post this so that when you DO do design videos, you know they are being appreciated.
Keep up the good work, and thanks!
