>"$5 Micro Tesla Coil 2,000V, 50Khz

Several surplus electronics companies sell very small hi-volt power supplies called

"fluorescent lamp inverters" or CCFL drivers.

In fact, these devices

are actually solid-state continuous-wave "CW" Tesla Coils:

they produce one or two kilo-volts at high frequency."

PDS: Apparently, CCFL's -- would seem to be analogous to being the "Raspberry Pi" (low end, cheap, affordable, etc.) -- of Tesla Coils...
