Beth Piver of Hoop Trix presents us with a fresh out of the box tutorial on how to make your very own rainbow LED hoop, a simpler one that doesn’t require you to do any soldering, and therefore there won’t be any switches needing to be installed either. Beth also imparts a clever little bit of wisdom on just how to transform your white LED’s into purple ones. What’s her secret? Simply shading them with a purple sharpie marker. Beth currently lives in Colorado Springs, Colorado, USA.
