My light powered Non-Stop running device
This is an led light that runs all the time on ambient light energy. It is a combination of projects which I have worked on over the years. I am calling this a “self-runner” because it operates day and night without stopping and the battery is a rechargeable not a galvanic that eventually goes dead. Machines don’t “make” energy but a device like this one can gather enough ambient energy in a home — to keep running non-stop.
