I think the original Gamecube component cable is overpriced, so I cloned it. =) Github repository here. Some random factlets because I'm too lazy to write a coherent post after typing all the READMEs in the repo:
我觉得原装GC色差好贵啊,所以我自己做一个吧。(最后一句话,看不懂,有不合法词汇)
The project linked above is basically a clone of the original component cable using only information that is already available on the net and some of my own observations on a logic analyzer. The board can output analog RGB (both CSync and HV-Sync available) or Component video. While I haven't calculated an actual BOM cost for the parts, it should be MUCH cheaper to manufacture than the current price for the original cable. The downside is that as far as I know there is no source for the original plug, so it has to be mounted internally in the Gamecube.
这个计划基于网络已有的关于原装色差的信息以及我个人逻辑分析的结果。该输出板能实现模拟RGB信号和分量信号。目前我还没有计算过产品的物料单。但可以肯定,自己做的会比原装的要便宜不少。不方便的是没有原装插口模具(这句不是很肯定),所以只能安装在GC内部。
