Basically I am trying to create a 19 ft circumference ring using an LED strip. I am looking for a way to be able to control the strip live with a computer screen. I saw someone find a way to select a point on their screen and assign it to an led and I would like to do something similar and for example play a spinning colored ring on my computer and have it align with the ring. I saw a T300k controller that can do what I am looking for but it cost $200, are there cheaper solutions? Thanks!
