Great hack/solution guys. I bought the power supply and my sensor is working like a charm. Didn't have to use the solder. Just cut it, melt the thin plastic around the red and orange wires (you cannot see it, but the red and orange color are actually a thin plastic cover), attach it to the power supply wires(red is the positive, yellow is the ground) and tape it.
Since the my power supply sits behind the TV, kind of a pain to have it disconnected, i will add a small led switch so it does not stay turned on all the time.
Thumbs Up from your Brazilian friend!
