Electrical things that also involve mechanical concerns

• Penetrators on electronics box and into the deck
• Slip ring going into mast
• Waterproofing exposed sensors/PCBs/connections
• Battery box inside hull
• Rotating camera mount?

Camera?

• Is it feasible to run computer vision on an ESP32
• Raspberry Pi that only powers on when the camera needs to be run to avoid drawing too much power? Or can we just unplug the raspberry pi for non camera tasks?

E-Stop?

• Is one necessary?
