Diy red-light therapy device

I’m starting to find interest in developing my own red light therapy device. I have hardware skills (soldering, arduino, embedded devices, etc.) and I’m also a programmer myself which is sort of an advantage. I know I can buy an off the shelf device but I’m interested in the process of learning along the way and experimenting.

I know there’s plenty of tutorials online but I’m interested in hearing your personal experience on the matter. Have you developed something similar from scratch? How has your experience been so far and what would you advise?

Thanks.
