PHANTOM POWER. A visual explanation of how some things can work even without a power connection!

A power wire came of my Neopixel ring, and it still worked!
It's not uncommon for a logic circuit board to power another via the data lines. Be warned!
Here's a quick visual explanation of the phantom power effect.
In the video, it was the GND wire that had become disconnected. However as it's almost always the positive supply that goes missing, I decided to describe the principle from that point of view. The effect will be the same for missing ground or missing positive supply.
