High voltage flyback for producing high voltage arcs, and high voltage experimentation. The internet has a great amount of information on using flybacks with simple driver circuits consisting of just a few electronic components. This one has 9 pins on the bottom and a 11"L high voltage lead on top. Size about 1.7" diameter x 1.8" tall (excluding bottom pins and top lead). Brand New.
DISCLAIMER: Brand new, but no specs, hookup info or other data. You should not buy this unless you are familiar with working with high voltages and should be careful to take all safety precautions when using this.
