What this video covers

The crew of a small aluminum tender designs and builds a custom dual-throttle control unit to manage two electric outboard motors.1:17 To minimize space and weight, they model the housing in a digital design program and fabricate the six-piece enclosure using a 3D printer with PETG filament for its mechanical strength and impact resistance.3:19 The internal electronics feature an Arduino microcontroller, which the crew wires and solders based on a digital schematic.8:13 They incorporate a waterproof connector for the cable assembly and integrate magnets into the base of the housing to allow for tool-free mounting on the boat.12:11 During assembly, the crew notes that the internal space for wiring was tighter than anticipated, requiring them to redo several solder joints with thinner wire.11:04 After finalizing the code and verifying the throttle signals on a computer, they confirm the system successfully controls both motors independently.14:45 The project demonstrates how 3D printing can replace improvised repairs with professional, custom-fitted marine components.3:58
