Electrical Control Box (12 V)
→ to GitHub project folderThe G6 integration has several loads that all run from 12 V: the heating pad, the optogenetic stimulation light, and the illumination panel. Rather than run a separate wall supply and loose wiring for each, we combine their 12 V power into a single laser-cut enclosure. The box gives every subsystem a common supply and keeps the wiring on the bench tidy and repeatable.
The front panel carries the connectors and controls for the shared supply: an on/off switch for the optogenetic stimulation, barrel-jack-to-screw-terminal adapters for the incoming and outgoing 12 V, a lever power splitter that fans the supply out to the individual loads, and a BNC-to-screw-terminal breakout for the stimulation trigger signal. The box is cut from acrylic; the only source files are the vector cut layouts.
Production files
The laser-cutting files live directly in the folder (there is no production/ subfolder). electrical-ctrl-box.svg is the recommended source for cutting.
