Todd from Toddfun has a few sets of Christmas lights but has an issue with the lights slowly going out of sync. This year he has come up with a way to solve the G35 LED Christmas Light Sync issue with a quick Hack. The two strands of lights have their own controller, you might think to somehow sync the controllers together or change to a common input clock for the two controllers but Todd has come up with a simple yet effective method. He simply chops one of the data line outputs that feeds one of the strands and feeds it with the data from the other controller. Then he commons the negative of the two power supplies which the data will be in reference with. The result is a nice simple, reversible hack which will perfectly sync the lights.Â
