Jacobs ladder and steel wool

Posted on 9. October 2015 in high voltage experiments

This article displays just some pictures made from a simple two wire jacob’s ladder with steel wool cover. The steel wool ignites and creates hot arrows shooting from the center of the spark gap.

Small Tesla Coil – 0,5 m height – 20W

Some pictures from my smallest Tesla coil, driven by a fly back transformer from an old TV and a 555 timer IC. This machine works at about 15kHz, and drives a single IGBT450 FET, with an operation Voltage of about 12V.
