This is a fan-made, and hand-drawn schematic of the Flux Capacitor as made famous by the hit movie Back to the Future. This is the schematic that Dr. Emmet Brown drew when he had his vision of the Flux Capacitor, which is what makes time travel possible. This is a nearly perfect 1:1 copy of the screen-used prop. It was hand-drawn, and is not a download from a fan site.
