As a kid, my father all ways asked if it was possible to control one light bulb/LED. Throughout the years, I kept it on my mind and 2015 I worked out how to do it make it happen. I was hoping it was going to be ready for Christmas 2015 but still having some problem with the waterproofing and decided to make it happen the next year. It took a long time developing the idea and even longer making the parts. They work pretty well but I think I make them even better.
