Previous tutorials used sketches to build the powercopy. This new method is much more robust and will not break like previous approaches did. There are times when using sketches makes sense but this method will be less likely to break down.

Based on feedback this video is much higher resolution (so it may take a minute to initiate depending on your connection speed).
It has also been a while since the last video tutorial and my settings were lost. I apologize for the poor sound quality and I will resolve this as I produce future tutorials.
