Ask HN: What is your side project for 2018?

I just started learning Developing application and I am looking for passive income ideas. I'm actively looking for income sources and my skills. I just launched http://ift.tt/2DkLJHa as a side project and adding new feature soon. I am learning php/mysql and looking for suggestions.
