The device also includes a visual multimeter that monitors the amount of energy stored.

This is an Amazing project. I love how he used printed paper to design the board layout and then glued it on top of proto-board. This would be great for camping or cabin use. I also love the simplicity of the design, using diodes to indicate charge of the battery is elegant if not inefficient.
