Team Vision for Final Demo and Handoff

The system is assembled and tested in a pool and outdoor streams. The RPM needed for the system to charge a phone is found and the electrical is finalized. The anchor system used is the electrical cord.

If the project where to be continued there are a few things that could be worked on:

Test Results Summary

Water Testing

The system is tested in a pool and in a stream. The system is water proof and durable. Water Testing Video

Electrical Testing

A tachometer is used to find the RPM needed to charge a device connected to the buck-boost converter. Electrical Testing Video

Risk and Problem Tracking

After final testing three risks/problems are still present. When tested the water was not moving fast enough to rotate the blades at the required 300rpm to charge the device. For future steps taken on this device an anchor system can be designed to allow the system to be self sustaining. Alternative motors can also be looked into. Including AC motors and other DC motors. An AC motor was testing during the development of this device, however, when a load was applied the torque on the motor was too high for our application.

Plans for Wrap-up

To conclude the project the system is going to be tested in a pool with slightly varied blades. The goal is to find the relationship of the speed of the water to the speed of the blades. The new blades will be longer and have a different angle.
