Relating to development a cut up keyboard, you’ve numerous choices in the case of the cable. Many will use a normal 3.5 mm TRRS cable, and others would possibly use one thing extra esoteric like RJ-45 to run between the halves. This simplest works in the event you’re the usage of two controllers; in the event you simplest need one controller, it’s a must to move the matrix from one facet to the opposite, which usually calls for greater than the 4 wires introduced by means of the aforementioned alternatives. Whilst rummaging round, [Joe Scotto] discovered a VGA cable and concept, why no longer use that?
This pretty Barbie-themed peripheral is a cut up model of an previous board he constructed referred to as the ScottoFly, which is a monoblock cut up with a void within the center. As with that one, that is hand-wired the usage 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 twine breakage sense, or so he concept. The actual downside became 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 move rows and columns. Then again, there have been nonetheless sufficient viable pins to ship the 4×5 matrix throughout. Make sure that to try the construct video after the ruin.
