I appreciate all the advice offered. I'm not a believer in antigravity. I just wanted to build and fly a lifter. I understand DC is best (or even the only thing to use), but when other people say I can use ignition coils or NSTs, I am curious to find out how. The Hamilton Drills induction coil does not do anything for the lifter but cause it to arc furiously, even using the HV diodes peddled by the maker.

So far only the flyback in the CRT has done anything for the lifters. I have built two of the triangular foil-and-wire type, powered by a CRT monitor. They lift, though not as well as I would like. The device seems very sensitive to the gauge and length of wire used to connect it to the power source. If anyone has optimal suggestions on that score I'd like to hear them.

My ultimate aim is to build a "thruster" on a spindle to demonstrate the concept to others. I guess I should build a flyback power source (there are lots of plans for them around), but I was hoping to use one of the devices I had on hand.

To avoid sparking, keep the corona wire at a larger distance from the body, and add a resistor in series with the power supply. Use several physically large resistors in series, for a total resistance of a few Mohm. Have the foil at the body bent in a round curve at the top, otherwise the corona wire vibrates.

I use #30 or #32 magnet wire for the connections.
