Universal cable connector
A fuzzy plug that connects to any electrical interface. A dense array of microscopic insulated wires captures and sends signals to the conductive surfaces in a connector. Noise and imperfections are corrected by a processing model trained on months of synchronized ground truth.
There's all kinds of crosstalk but the hyperheuristic processing model has seen it all and can thus easily offset it. The main benefit is that you can talk to any device, no matter how old or obscure its interface is. Many beneficial corollaries follow.
John and Fen use these microbrush connectors to fire up various electrical devices found on surveying expeditions. They often hack together ad hoc combinations of devices using the dynamic slaving scheme editor.
