Water Wireless Circuit – 2 LED bifilar
An experiment that worked out quite well, running a wireless electricity circuit from water in an unconventional way. Features ———— The transmitting bifilar pancake coil has 1 wire disconnected – leaving only 3 used…
Wireless electricity – circuit power retainment
An example of wireless electricity experiments (more within my YouTube channel). Here we have a dollar store type of flashing lights circuit, that has some interesting traits. The flash type can be set with…
