I was wondering about that. I set one of those up a few years ago on a breadboard. It was a fun project (for this non hardware guy) and somehow very satisfying to watch a "dead" AA power a bright blue LED for weeks. I wonder how the device will perform in the real world. Where do I sign up for announcements?
