When seen in the same room this prototype looks like a magic trick, but when placed in different locations it gives a sign of remote presence: I light a candle in my room, a (LED) candle is lit in your room. When I blow out the flame of my candle your light goes out as well.
Technically quite basic with a light sensor connected to a controller on one side, and a modified LED candle connected to the controller via a transistor circuit on the other side.
Everything is contained inside the candle holder.
One thing I would like to try out is to have several “receiver” candles in different locations.
