Write problem/project Goal
My goal is to work with my team to create working speakers, and a corn starch mixure that will allow us to create a corn starch monster

My First Task
I am going to look up possible ways to configure a system with the arduino that would make the speaker functional, then I will collaborate with my teamates about which system would best suit our project.

Summary of actual work over first weekend
I originally though that I was going to be using an arduino. In the end it turned out that am ocsillator was what we need to make.

Week1 Narrative
I did some internet browsing to see what we would need, and on how we would be building our oscillator. I discovered that not only can you make combinations of resistors to get a certain amount of resistance, but you can also combine capacitors to get a certain amount of capacitance. Aligning these devices in different ways can determine the amount of resistance and or capacitance generated.

My Second Task
I plan on assembling the ocsillator.

Summary of actual work over second weekend
I basically just messed around with the oscillator. I was able to look off of this diagram, 50 Hz Oscillator. In the diagram, you should pay more attention to what number is connected to what number rather than try and mimic the wire pattern.

Week2 Narrative
I went to Home Depot and I cut and stripped a lot of wires, and I connected them to the circuit board.

My Third task
I want to finally get the oscillator working. And hook it up to the speaker.

Summary of actual work over third weekend
I actually ended up working on and improving upon the wire configuration on the bread board. The regulator was not completly hooked up. So I cut and stripped some exrea wires to accomidate for it. The resistors ,originally were not hooked up either. I decided to swich the ones I had with some other ones because they did not fit. I looked up this video, |Physics 13.4.2d - Resistors in Series and Parallel, so I could find a way to assemble thed resistors in a series circuit.

I was able to test the circuit; you can look on our team page for some pictures.

Week3 Narrative
I was able to continue working on the oscillator,

My Fourth task
I want to get everything working and assembled so we can get the corn starch made and put on the speaker. ''

Summary of actual work over fourth weekend
So I was able to get all the parts for the oscillator again since the other one went missing. I reassembled the oscillator. Unfortunatly it is not working as well as the original one was; however there is still current going through it.

Week4 Narrative
I got the parts I ordered off of Ebay; the 7490 divide-by-ten chips. I put the oscillator together and started to test it. I got some action out of it; however, the circuit itself was not producing the 50hz that it was supposed to. The only thing that I can think of is that the resistors are not lined up correctly because that was a reoccuring issue in the past. I would have to do more testing to be sure.
