Introduction: Home Made Varible Ballast!
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
We have a be nice policy.
Please be positive and constructive.
