Famicom AV mod

My custom composite video modification for the Japanese version of the Nintendo Entertainment System, the NES.

Changelog

Version 1.2:

V1.2 PCB

WARNING: STILL NOT TESTED.

Added a rectifier bridge to accept power bricks with any polarity.
Replaced fuse with a automatic resettable fuse (PTC), which is smaller and does not need maintenance.
Slightly tweaked position of switches, which weren’t centered relative to the case holes.
Replaced switches with double rocker switches which are closer to the original ones in the Famicom in terms of size.

Version 1.1:

V1.1 PCB

Current revision in use for installation in consoles.

Added support for the HC Famicom revision, which has a different video section and PCB layout.
Added support for the power rocker in the H revision, which I forgot to include in v1.0.
Added switches on the back of the console, one for controlling the smoothing on the H revision and a decorative one.

Version 1.0:

First revision.
Only used in a single console.
