A commercial Solar Light
I was clumping through a common staff area the other day and spotted a solar light (with a PIR) for sale through some charity.
The packet claimed that the unit didn't need electricity, batteries or wires! Free energy??
It was only $12 (a great deal cheaper than similar units found in the shops) and I was intrigued to find out what was inside. I suspected that a battery was in there, and I was hoping for a QX5252 based (or similar) circuit whereby I could point and say "Oh, I understand that!"
It was not "to be (or not to be)" as the video below shows - there were surprises...
