Write problem/project Goal
Create a Wind Tunnel for other projects to test aerodynamics.

My First Task
Mount motor in wind tunnel part. Look for Straws!

Summary of actual work over first weekend
Found Some Straws and Started to find the materials for mounting the motor in the propeller housing.

Week1 Narrative
The straws we need: 8.5 inch Straws 200 for $1.90

My Second Task
Mounting Motor, Refining control scheme, Run motor off new power supply

Summary of actual work over second weekend

 * Attached Motor to inside housing
 * Trouble shot Motor and power supply, got it to run correctly off new power supply
 * Tested, then removed new control scheme.

Week2 Narrative
The wooden bar in the center of the motor housing was put in and the I assisted in mounting the motor to that bar.

Next the wiring was sorted out and the entire housing can function, Testing soon followed, but the ESC was not functioning properly. Even with the use of the new power supply, the Motor spun backwards before starting a very slow spin, then stopping, then starting again.

The new control interface was added, with a switch so a speed could be selected and the motor turned off without having to change the poteniometer position.

Since the motor was not working, the was taken out to ensure this was not the problem that needed to be trouble shot.

The issue first arose, and normal power supplies were being used. Switching to another more durable and more consistent supply allowed for the elimination of the possibility the problem originated in the power supply. This took some work as the wiring was not compatible and a wire needed to be made and connected.

After the wiring was sorted and the new control scheme reverted to the older one that was sure to work, the Motor still did not spin up correctly, and also did not emit beeps when first plugged in and before it started, though it still flashed the red light.

Once I had realized that the problems arose after we disconnected the motor from the ESC to mount it, and it blew air in the opposite direction briefly before this behavior, I reversed the wire connection between the ESC and the motor, fixing the problem as this had happened when I reconnected the motor and ESC after mounting.

My Third task
Better Shroud in Motor Housing

Summary of actual work over third weekend
How is what you did different than what you planned?

Week3 Narrative
The non slip pads for the wind tunnel:Non-slide Pads

Link for a possible scoring tool Scoring Tool

Looking into scoring plexi with a box cutter using scrap pieces.

My Fourth task
I am done, going to assist partner in project and record what is necessary for future project workers.

Summary of actual work over fourth weekend
How is what you did different than what you planned?

Week4 Narrative
Tell a detailed story describing what you did for your team over the weekend.
