This small battery powered red and green light is a work in progress. Eventually the battery will fit into the wooden box. For now it is hanging out in my homemade holder- seen above. Currently, (pun!) we are doing a battery test on it- just checking to see how long the battery will last. So far it has been about 72 hours. Soon the real battery holders will come. This one is made out of a safety pin and cardboard. It’s pretty touchy.
