Flashing a light with kinetic motion

For this week's assignment, Tim, Aileen and I gathered together to explore the concept of kinetic energy generation and using that to flash a light for a short period of time.

Both Tim and I have experience with electronics in general, so we explained a few concepts to Aileen and did the exercise together.

We basically hooked up an LED and a motor together. By spinning the motor with our fingers, a short burst of current flowed thought the circuit and lit up the light.

We noticed that the light would only flash for a bit and tried adding a capacitor in parallel to the LED to see if it would stay lit up for longer. We achieved very unreliable results, but it was a good experience overall.
