Fixing a LED Christmas Tree Controller using Costco / GE 29V Power Supply. GT-30V12, GT-DL8-29V
In this video I investigate a failed power supply and controller for our Christmas tree. Voltages, current, LED string connections and theory are discussed.
I will look at making a custom circuit board to better control the Christmas tree.
In this video I used and purchased:
H Bridge Controller: amzn.to/3ZUIlxz
Power Supply: amzn.to/40aUgsy
Quiet Fan: amzn.to/4gSqONv
Rigol Power Supply: amzn.to/4a1ZJW4
Rigol Oscilloscope: amzn.to/41Q1FPa
