Week 4: Update

Jacob went out and picked up the fourth motor for the design (above). We've decided that we are going to use the motor as a boost instead of as a strafe motor. After checking a few local hardware stores, we have determined that we will have to get our extra PVC fittings online. We plan on purchasing these today.  These fittings include 4 corner pieces, which allow for a 3 dimensional connection, and a valve that we are planning on using to fill the submersible with water in order to make it naturally buoyant.  If the valve costs to much, we will not be buying it, and will replace it by drilling holes, and filling them with stoppers.  The corner pieces should only cost $1.43 a fitting, making an additional $5.72 for 4 fittings plus tax and shipping.

The wiring of the control box and the submersible should be finished by next week as long as we get the rest of the pieces in time.

Cost of motor: $6.35
Total amount spent so far: $21.37
Estimated final cost will be under $40.
