In-class presentations in Week 8 (3/12/08).
Overview:
Design and prototype an electronic device that runs on energy available from the immediate environment.
Step 1: Choose and document a specific problem space.
Step 2: Propose a solution to address the problem in Step 1.
Step 3: Develop a prototype that convincingly demonstrates the viability of your proposed solution in Step 2.
Requirements:
Prototype
Develop hardware using the kinetic or solar concepts presented in class. The object must run only on energy provided by the user and/or the ambient environment (no primary batteries, no plugs, no fuel). Charging batteries is not in itself a useful solution - what are the batteries for? The prototype can be inexpensive and/or simple but should serve as a compelling proof of your larger concept.
Presentation
Provide background information on your chosen problem space and solution.
Provide technical details for your solution, including a detailed, numerical
energy analysis of your device. What is your power source in watts? How are
you converting this power source to electricity? How long must you "charge"
or otherwise energize the device for it to execute its designed function (i.e.
what is the total energy (in joules) for operation). Demonstrate your working
prototype.
Extra credit: Convince the class that your device can save the world.
