Hey Xin,

Thank you for making this repo/code available. Much appreciated and needed. And thank you for making everything clear and easy.

I can't offer you a job but I wanted to invite you to check out my project because I want to supplement it with the hardware design/proof-of-concept and I would love to hear any feedback from someone like yourself. It would really help me out to improve and learn.

The hardware part is very simple and built upon/relies upon a popular Raspberry PI

Here is the direct link. Also, check out my other repos/links.

Thank you very much.
