Did anyone ever notice that Bad Brain's electro thingy from DTOSC is pretty much the same as the polarity circle from BACALAC?

Actually it would be similar because of the FBI (F= Force, B= Magnetic Field and I is current) law in physics in which the magnetic field is in relation to the electric field as well as force. A magnetic field can be used to create electricity (actually that is the way electricity is produced) and vice versa so it doesn't surprise me that Bad Brain's electro thingy is the same as the polarity circle that Bob used. They'd be the same thing but they'd be the opposite of each other. Bad Brain's device would use magnetic forces to generate the electricity needed to turn someone to ashes. While the polarity circle would use electricity of realign Bob magnetic field.
