bifilar Tesla pancake wireless coupling.wmv
This is a test with a Tesla bifilar pancake coil (made à la Jiffycoil methode). The wiring is on a standard Joulethief circuit with a TIP 31C transistor for voltage up to 24 volts (probably more is possible but my led ramp is already at the max lighting at about 15 volts). The receiving pancake coil is a simple wire (not bifilar as i sayd in the video) with 23 turns o.5 mm plastic insulated copper wire . The led ramp is 60 leds And what impressed me is the distance of the coupling Enjoy
