Cluster Wiring - cjus/hydra-cluster GitHub Wiki
The wiring for the cluster was a primary concern. The goal was to minimize the amount of wire used for both practical and aesthetic reason.
To keep wires neat, they were cut to minimize size. Severed wires were then reconnected and soldered before wrapping in heat shrink tubing using a heat gun.
Rounded plug connectors were attached to keep the cluster components modular.
Computer wiring
USB charging hub
Power to the computers is delivered over flat Micro USB sync cables from a powered 6 port USB charging hub.
Ethernet wiring
The computers are networked together using flat 6-inch Ethernet patch cables connected to a small 5 port network switch. I have a preference for flat cables, but you can certainly use rounded cables.
