For this project, we were asked to make a functional lantern that is aesthetically pleasing, creative, and maximizes light. Each student was given one battery and one LED light.
Immediately after getting this assignment, I had a pretty clear idea of what I wanted my lantern to look like. I wanted my lantern to be adjustable to move the light to where it was needed. To achieve this, I gave leeway by adding extra paperclips as wires. To make it adjustable on a manual level, I attached the light fixture to a pencil and put it in two holes that I carved into foam for support. To turn the light on and off, tie the strings that are attached to the pennies. This will make them touch and allow the electricity to flow. To turn light off, simply loosen strings. This was a great project to start out with because we were able to quickly adapt to the "limited" amount of materials that we're allowed to use to build with. Below are some sketches of my light and the actual product itself.
This was the initial sketch, which ended up not being too different from the final sketch of the lantern. The equation reads as follows:
V=IR
9V-3.2V=(20mA)R
5.8V=(20mA)R
5.8V=(.20A)R
5.8V/.02A=290 ohms
resistor=290 ohms
resistor actually used-270 ohms
This is a clearer sketch of the final product once I had a more clear vision of what I wanted my lantern to look like and how I was going to build it.
I love how you used the pencil, pennies, and string Alexandra! What stood out about your lantern was that the direction of the light could be adjusted, which can be very useful. This was really creative and inspiring. :)
