GO-GO AirBoat

##GO-GO AirBoat is a physics concepts and electronics learning kit that sparks imagination. GO-GO AirBoat is a motorized, propeller airboat that's always ready for adventure. When it reaches full capacity, watch the motor rev up to life, spinning the propeller, and get ready for action! How many pennies can you load before GO-GO takes off? Will it sink or will it float? Load your cargo containers with up to 20 pennies each (US cent tested) and wave goodbye as GO-GO sets sail! Load your cargo containers with creativity and experiment with different combinations of load and weight distribution. The cargo containers are infinitely stackable, and the cargo bay area can support up to 5 columns of containers. Provided instructions include a derivation of the "Maximum Number of Pennies" equation to stay afloat with your chosen cargo configuration. Simple to print! With just four STL files needed to construct your GO-GO AirBoat and cargo containers, it's easy to bring this learning kit to life. GO-GO AirBoat senses when to embark on its journey across the sea when it is fully loaded to capacity with its valuable cargo. A floating piston inside the boat's smokestack 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 can be mechanically altered using different, floating piston heights of your own creation. Gain hands-on experience with resistors, capacitors, diodes, LEDs, DC motors, bipolar junction transistors (BJTs), Darlington pair transistors, phototransistors as triggers, circuit board layout, and soldering. The GO-GO AirBoat features a series of basic, discrete component, electronic constructions to help young engineers and future scientists better visualize electrical components, their wiring, and their roles in electronic circuits. The instructions provide step-by-step calculations and descriptions of how the individual circuits function together as a whole. Use this model as an activity or introduction to subjects such as weight, mass, displacement, density, buoyancy, and center of gravity. Topics covered within the instructions focus on mass, density, and basic algebra. Logic and reasoning skills are exercised to translate calculated values to the real world. Designed by David Choi
