Introduction: Home Made Varible Ballast!

About: backyard physics and high voltage
This is my attempt of coming up with a way to control the amount of amps going into my pole pig, using two microwave oven transformers wired  to draw 7-14 amps,  the  MOT transformers were modified by cutting part of the core so it can move and vari the inductance.


I did some tests and it does work for limiting the power, but will draw a minimum of 3 amps per transformer
