Flyback Transformer Driver - This is by far the best project for someone who is already familiar with High Voltage, but wants to take their experiments to the next level: It requires very little previous experience and skills with soldering and identifying components, and there are virtually no adjustments to be made. The danger is minimal, as fly back transformers are intrinsically low power devices, not capable of outputting lethal currents (due to the hair-thin secondary windings), and yet it will give a careless experimenter a nasty RF burn if he accidentally touches the HV wire (nothing beats learning from your mistakes). If you have never experimented with HV before though, I recommend you start off with an electrostatic project. This circuit is not a toy! __ Contact: Sam Barros
