- GO-GO AirBoat is a payload-sensing, motorized, propeller airboat.
- When GO-GO AirBoat reaches full capacity, watch the motor rev to life, spinning the propeller, and watch GO-GO go! How many pennies can you load before GO-GO goes? Will it sink or will it float? Load your lifesavings aboard, and wave "Bon voyage!" to your GO-GO AirBoat!
- Load your cargo containers with up to 20 pennies each (US cent tested). The cargo containers are infinitely stackable! GO-GO's cargo bay area can support up to 5 columns of cargo containers. Many combinations of load and weight distribution possible. Experiment!
- Provided instructions include derivation of the _"Maximum Number of Pennies"_ equation to stay afloat with your chosen cargo configuration.
- Simple to print! There are only four STL files needed to construct your GO-GO AirBoat and cargo containers so it's easy to do.
- GO-GO AirBoat senses when to embark on its long haul across the sea when it is fully loaded to capacity with its valuable cargo. A floating piston inside the boat's smokestack is free to move with the water level and triggers the motor to drive when a certain depth is achieved. This sensor employs a simple infrared LED, phototransistor, and a Darlington pair transistor amplifier stage for switching of a small DC motor.
- The depth-sensor trigger point…
