Desolder \u0026 Tear-off RF \u0026 PSU board\n2. Extract 4 pin jumper connector\n    - VCC\n    - GND\n    - Video\n    - Audio\n2. Desolder Power Switch\n3. Solder 2 x 4.7uF capacitors to reduce jailbar effect(I don't know how it works)\n4. Solder Power LED with 330R register\n\n### Build daughter board\n\n1. 4 pin jumper connector(male; connect with Step. 2)\n    1. VCC - Power Switch\n    2. GND - GND\n    3. Video - 0.47uF capacitor - Collector of C1318\n    4. Audio - **Audio Output**(TODO: Stereo?)\n2. USB-C connector\n    1. VCC - Power Switch(center)\n    2. GND\n3. C1318 Transistor\n    1. Base - VCC\n    2. Collector - 0.47uF capacitor \u003c- FC Video\n    3. Base - 22K resistor - Collector\n    4. Emitter - **Video Output**\n    5. Emitter - 22K resistor - GND\n4. 3.5mm 3 or 4 pole connector\n    - NOTE: we have no stereo!\n    - NOTE: 3.5mm 4 pole connector is varying by manufacturer\n    - 3 pole connector\n        1. Audio Left - Audio Output(from 1.3)\n        2. Audio Right - Video Output(from 3.4)\n        3. GND\n    - 4 pole connector\n        1. Audio Left - Audio Output(from 1.3)\n        2. Audio Right - Audio Output(from 1.3)\n        3. GND\n        4. Video - Video Output(from 3.4)\n\n### Some photos\n\n![Tear-off RF \u0026 PSU board](tearoff_rf_board.jpg)\n\n![Test Video Output](test_video_output.jpg)\n\n![Test Daughter Board](test_daughter_board.jpg)\n\n![Connect Daughter Board - Top](daughter_board_top.jpg)\n\n![Connect Daughter Board - Rear](daughter_board_rear.jpg)\n\n### References\n\n- [Nintendo FAMICOM Mod (USB Power, Composite Video, Stereo Sound)](FamicomMod.pdf) (web link is dead)\n- https://miko.mobi/famav.htm\n- https://8bitplus.co.uk/your-consoles/famicom-av-mod/\n- https://8bitplus.co.uk/projects/famicom-av-mod-nintendo/\n\n---\nMay the **SOURCE** be with you...\n\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fiolo%2Ffc-av-mod","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fiolo%2Ffc-av-mod","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fiolo%2Ffc-av-mod/lists"}
