Creating a Light-Tracking Servo
Students will learn how to program the Basic Stamp to use information from two photoresistors to point a servo at a light source. This will be the first degree of freedom for the flower head.
Dual Axis Light Tracking
Students will take the previous lesson and apply them in creating a light tracker with two degrees of freedom. The axis of rotation will be about the horizontal and vertical. Teams will have everything they need to make this build work. They have already...
Integrating Solar Power
At this point students should have a working robotic sunflower that will track the sun with 2 degrees of freedom. This next lesson powers the whole system with a photovoltaic module. A Zener diode is used to charge a 6V motorcycle battery which then...
Solar Battery Charging
Students will become familiar with circuits, cells, batteries, and photovoltaic cells, then plan, build, test, modify, and re-test a small solar battery charger designed to maintain batteries from a particular device.
Solar Site Assessment
Students will do an actual site assessment to determine the available solar resource for a chosen location.
Can Portable PV Charge Vehicles?
In this lesson, students will begin to explore the potential and challenges related to using photovoltaics to supplement the power needed to charge batteries in BEVs. Students will test a variety of wiring options related to series and parallel wiring....
Designing a Solar Charger
In this lesson, students will further explore the potential and challenges related to using photovoltaics to supplement the power needed to charge batteries in BEVs. Students will be provided with a 12 V lead-acid battery and several 3 V, 1.5 A solar...
Photovoltaic Solutions "Shark-Tank Style"
In this lesson, the students will take their knowledge gained in the previous activities to innovate design solutions that will allow PV technology to plan an increased role in the transportation sector. The challenge given to them is to design a BEV that...
