Many will use an ordinary 3.5 mm TRRS cable, and others would possibly use one thing extra esoteric like RJ-45 to run between the halves. This best works when you’re the use of two controllers; when you best need one controller, it’s important to go the matrix from one aspect to the opposite, which usually calls for greater than the 4 wires presented by means of the aforementioned alternatives. Whilst rummaging round, [Joe Scotto] discovered a VGA cable and idea, why no longer use that?
This pretty Barbie-themed peripheral is a break up model of an previous board he constructed known as the ScottoFly, which is a monoblock break up with a void within the center. As with that one, that is hand-wired the use of thicc brass insulated with heat-shrink, makes use of a cast 3-d-printed plate, and a published case. And prefer a madman, [Joe] coiled the cable.
Sadly, this proved to be problematic within the cord breakage sense, or so he idea. The actual drawback grew to become out to be that the center row of pins on a VGA connector all act like flooring, so they may be able to’t be used to go rows and columns. On the other hand, there have been nonetheless sufficient viable pins to ship the 4×5 matrix throughout. Ensure to try the construct video after the spoil.
