Week0 Task

 * My last project is Stirling engine.
 * Figure out what is Stirling engine and how it works.
 * Figure out what I can do for this project.

Week1 Narrative

 * Professor assigned me to assemble Stirling marble engine kit, so I put the parts together and tried to make it work.
 * I recorded what I've done so far and some problems which makes it not to work on my CDIO page.
 * Here is my /CDIO/ page.

My Second Task

 * After I changed the torn balloon with the new balloon, it still doesn't work properly, so I need to figure out what makes this machine doesn't work.

Week2 Narrative

 * The placement of the test tube is really important to work this engine. The test tube has to be slightly tilted to the right where is the rubber stopper so that when the balloon goes flat the marbles have to go to the right.
 * So, I moved the test tube from the horizontal position to the right a few times, around 0.5 inches each time.
 * I found the position where the marbles goes to the left when I heat the test tube, but still they don't go back to the right.
 * I've been trying to find the error sources which make this engine doesn't work.
 * Here is my /CDIO/ page.

My Third task

 * I still doesn't make this engine work properly, so I've been focusing on the source of errors.
 * I need to figure out why it doesn't work and to try other solutions to fix this engine.

Week3 Narrative

 * I did the test for the second attempt but it didn't work well so wrote down what could be developed on my CDIO Page.
 * According to the professor's command, the reason why the test tube doesn't tilt back to the right is that I put too much heat at the bottom of the test tube, or I put too much air into the test tube. I did the third attempt.
 * I tried three different solutions to make this machine work and recorded what I've done on my CDIO page.
 * Here is my /CDIO/ page.

My Fourth task

 * I haven't still found the solution to make this Stirling marble engine work well.
 * Find out and think about the way solve this problem.
