1) Patreon - I'm working on a campaign right now. You have to be very dedicated, however. Why I haven't thought about it until recently 
2) Google Adsense on a website that is similar to your channel, but maybe offers different/more detailed content
3) Amazon Affiliates - You can post links in your description! I don't make much but I think it will add up after time
4) Consulting - If you do well enough, people are going to want to know how you did it. I know Tim Schmoyer at Video Creators charges $300-600 for sessions. Consultants make a lot of money in any industry because they offer something valuable - knowledge.
There's a few more in Tim's stickied post in the general forums. Take a look!
