One quick question though. If I turn off the electric to the base, would the magnets keep it floating and just kill the lights?
NO! It's an electromagnet that requires power be constantly turned on and off hundreds of times a second to keep it floating. If you cut power it will crash.
It is highly recommended to get a battery backup in case you lose power, that way you'll have extra time to remove it from the base or for power to be restored before it crashes.
I'm glad you enjoyed building it. and thanks for your testimony that they're very simple to build. I think people don't give themselves enough credit. It really is fool proof.
