VGA2NTSC KiCad Conversion/Modification
This is a modified version of Mike Chi's VGA2NTSC v1.1. The first goal was to convert the original Altium source files to KiCad - a free and open source tool - as not everyone has access to Altium. Secondly, most footprints have been swapped to make the board more DIY friendly - for example swapping 0402 components (difficult to solder by hand) with 0805 or larger.
