You are looking at a very simple free LED Light Power from your very own house phone line. Material needed: 1) 2 pcs 33K Ohm Resistor, 2)1N4007 Diode (Prevent reverse bias of white led when phone ring ~ 100VAC), 3)3 pcs High Brightness White LED and a RJ-11 plug with phone cable.
Connect all these parts as shown in the video. There you go....... It can brighten up your house...at least you are not in total darkness. With this configuration, it will draw about 3mA at 50VDC of power from your phone line. With such a small current being drawn, my house phone and ADSL still working fine. Enjoy......
