Write problem/project Goal
The project goal is to finish building the corecontrol unit and begin the testing phase.

My First Task
I plan to create a list of possible solutions for creating a vacuum seal for the corecontrol.

Summary of actual work over first weekend
This week I searched online for possible materials to provide a vacuum seal for the corecontrol. I also received some possible solutions from other engineering students during our class presentation. I went to Harbor Freight and looked at several gloves that I couldn't find at other hardware stores, but they were either too big or too small to fit on the corecontrol. I found a pair of latex gloves at Walmart and tested it out on the corecontrol and was able to create a vacuum seal.

Week1 Narrative
During our class presentation, I wrote a list of solutions I had and asked the class for other ideas I could look at to create a vacuum seal for the corecontrol. The list I provided included a neoprene arm sleeve, a sleeve of a wetsuit, arm length neoprene gloves, and the sleeves of the a HAZMAT suit. The possible solutions I got from the class included: a inter-tube from a dirt bike, a sleeve from a hot suit, rubber oilers glove, and arm length latex gloves. After writing down the new list, I tested out the corecontrol using a latex glove with a rubber PVC extension and was able to create a small vacuum, however the seal easily broke if I moved my arm around. In addition, it was very uncomfortable, which may draw potential users away from using it. I drove to Harbor Freight Tools and looked for several gloves I could use for a vacuum seal and found Long Rubber Gloves, but they were too wide to fit on the corecontrol without major modification. I also looked at Nitrile Gloves, but they were too short. I finally went to Walmart and found a pair of Latex Gloves that were forearm length and decided to try it out. I tested the new Latex glove and was able to create a vacuum seal.

Here are other possible solutions:

1. Neoprene sleeve

2. Oiler Glove

My Second Task
My second task will be to create a vacuum seal with a pair of oiler gloves, long rubber, gloves, and neoprene gloves. After I have created the seal, I will beginning testing the corecontrol to see if the corecontrol will reduce recovery time and increase strength and endurance.

Summary of actual work over second weekend
This week I tried to create a vacuum seal with a pair of latex gloves. After several failures, I removed the gloves altogether and used a rubber PVC pipe reducer. I adjusted the open end of the pipe reducer with a clamp and was able to create a seal when I inserted my arm.

Week2 Narrative
This week, I attempted several times to create an air seal for the corecontrol using latex gloves. On my first attempt, I cut out the palm area of the glove just enough to create contact between my hand and the brass pipe. I also cut the glove at the mid-palm section, but on both attempts I could not create a seal. On my third attempt, I cut off the hand section of the glove and tried creating the seal from the wrist, but I ended up with the same results as the first, the glove was still too loose. I then tried a different type of latex glove and got the same results.

My Third task
For my third task, I will try to find a user friendly clamp because the current metal clamp requires a screw driver to adjust it.

Summary of actual work over third weekend
Search online for several straps I could use for the corecontrol and found these sites:

Buckle Strap

Buckle Strap 2

Week3 Narrative
Over the week I searched for possible straps I could use to tighten the opening of the corecontrol around the forearm. I did a google search for buckle strap and found several sites with potential solutions. All of the straps were very simple and would require minimal work to attach them to the corecontrol. I also searched for buckle lever and found more possible solutions

My Fourth task
My next task will be to find an adjustable fastener or strap to attach to the open end of the corecontrol.

Week4 Activities
Went to LOWEs, Home Depot, and Ace Hardware to find a adjustable fastener, but couldn't find one. I did find a couple online that will need to be ordered.

Week4 Narrative
I went to LOWEs, Home Depot, and Ace hardware to find a buckle fastener, but none were sold at any of the locations. I found several lever buckles/fasteners online that will need to be ordered.
