Here i am trying a diferent circuit setup in reguards to the DOVADA device setup. I am useing a tesla pancake bifilar coil as the inductor,and a signal generator .\r<br>\r<br>\r<br>\r<br>\r<br>\r<br>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 .
