This project will go about making a DIY solar-powered boat prototype. However due to a few problems on our main PC, we were unable to give the circuit diagram for the same. We will soon supply the diagram.
I built this project when I was in the 6th grade, for a competition at the IIT Techfest in Jan. 2010. The IIT Techfest is a competition for engineering students. However, my love towards making this brought me into making this project guide. I am now in the 8th grade! We have not given you the measurements of the parts so that you may go and design your own boat and its parts. We have only given you info on how to assemble the entire boat.
Double up 2 of those bases and keep 1 base separate.
Add the pair of fins you have to the bottom of the base, one on each side. Add your extra single fin on the bottom as well, centered between the pair of fins. Place this smaller fin toward the front and not towards the rear of the boat.
Make 4 stands of squares using the 12 square pieces we cut, grouping them in groups of 3. Hence, 3 x 4 = 12.
Place these 4 pillars towards the corners of the boat on the top side and stick them there using some double-sided tape or even normal craft glue.
Now stick the extra piece of styrofoam we cut to our base on top of those four pillars so that it acts as a roof!
Cut a gap in the roof for the wires from the solar panel to come to the motor.
Using a multimeter, check the polarity of the solar panel by placing it in the sun and measuring the voltage produced. Be careful. It is advisable to use a diode so that the current doesn't flow back into the panel. Stick the base of the panel on the roof using some double-sided tape and pass the wires through the gap you cut.
