You’ve probably heard of those power bands that are supposed to boost your energy and balance …or something. You know, the ones that magically work really really well in every country except the ones with decent advertising regulations? Yeah, those.

  1. This project uses dry cells in series-parallel. But Ladyada says not to do this in her LiPo tutorial: http://www.ladyada.net/learn/lipoly/
