Welcome to my space!

I'm Huanyu Ren, a PhD student at MIT Chemistry department who enjoy stargazing and making things. I'm also an astrophotographer so all space backgrounds you see here came from my own camera!
This site is my journal for the "How To Make (Almost) Anything (HTMAA)" course at MIT, where I document my trial and error for assignments and final project. Feel free to explore and see what I've been up to!
