Welcome to steemit champ! It's a big community here and finding a niche is one of the best way to stay focused on here.

That being said, it'll be ideal if you join the build-it, it's a community that accommodates all DIY (do it yourself) and How-to tutorials, since you're an electrical engineer you can post about it with pictures and steps (and video if you like) and the community will reward you fairly.

You can joing their discord channel and interact, here's the link ===> https://discord.gg/gQNZD4

Once again, welcome to steemit ;)
