A PCB coil can not practically have enough inductance for these lower frequencies, thus Niklas’ design employs a very high frequency indeed for a Tesla coil design, 2.6 MHz with both primary and ...

Tesla is recalling more than 376,000 vehicles ... will overstress motor drive components on the printed circuit board (PCB), causing a loss of power steering and requiring increased manual ...

So when [Daniel Eindhoven] sent his no-wind Tesla coil into the tip line, it immediately got our attention. The genius in his design is that the coils are actually etched into the PCB, completely ...
