The know-how is one thing, maybe I could do another more in-depth tutorial, I am wanting to make more lights for video use as well. So what I'm saying is the know-how can be easily remedied, but the other thing is time like you said! It does take a bit of time, but I guess it comes down to how much time/vs money, it's going to come down to those two in the end either way whether buying or making your own. And it is getting hard to compete with some of the prices that you can get nowadays with the pre-built lights so building it comes down to just having some fun... as well as utilizing some components that I had lying around. I have some more heatsinks, will just have to get some different colors and could get around to doing some stuff like this with arduino. Thanks for stopping by.
