I have a small idea for a performance, and I wonder if anyone have already thought about this and has any clue on how to realize it.
Is there any one that attempted to light for a small period something like a led harvesting rfid near field energy?
I explain myself: imagine I have a small device that is composed by a RFID antenna and a small condenser. The passage of the antenna in proximity with RFID signal emitter could load the condenser and the condenser in turn light a led. Fade in and out effects are in this came welcome.
Is there anyone that thought about this? Has anyone any idea on how to build it? Or who to ask?
