Using the concepts of heat and a thermoelectric generator, we had to come up with a toy or device. Our group designed a boat which would harness the power from a candle to generate electricity to power the motors hence driving the boat forward.

The hull of the boat was made using lasercut acrylic which was bent into shape. The propellers and candle holder were 3D printed. (We didn't really had to 3D print the candle holder but the lab was closed and we only had access to the 3D printers then.) The circuit was simple, comprising of one peltier chip acting as the voltage source connected to two motors in parallel.

It was a fun experience working with Nikhil, Hao Qin, John and Pei Xian. It was also my first time experimenting with bent acrylic and I was quite impressed that the hot glue could hold and did not let any water into the hull. Working on water was defintely more challenging but it definitely made us stand out from the other groups.
