High voltage pulse generator to simulate electrostatic discharges

This circuit was designed to check the roboustnest of other circuits against electrostatic discharges (EDS). It provides a repetitive train of high voltage pulses that can be applied to the circuit under test. In addition it is built with components easy to find around in the lab, like a small power transformer and switching transistors salvaged from a broken compact fluorescent lamp. Also a high voltage capacitor was built out of a piece of PCB board.
