A small wind turbine with a total height of half a meter will be used to generate AC power which will be converted to DC power. The DC power will charge (ideally) a removable battery pack that would have an output for charging a phone.

Solar phone chargers are great but they do not work when there is no direct sunlight. This turbine will fill that gap.

For this project we will:

1. Create power electronics that will convert the AC power to DC.

a) This circuitry will also include protection measures such as short-circuit protection

2. Implement sensors that detect wind speed and direction and software that will suggest optimal turbine turbine orientation.

3. Using the sensors implement, a cut-off mechanism to keep the generator and/or power electronics from being damaged from excessive wind speeds.

4. To scale the project's difficulty we would design our own battery pack using SLA's and implement a battery management system as well.

The mounting system will be a removable strap that would let the user secure the turbine as well as holes in the base that pegs could fit through to secure to the ground if need be.

Amphibious Spherical Explorer

Featured Project

The amphibious spherical explorer (ASE) is a spherical robot for home monitoring, outdoor adventure or hazardous environment surveillance. Due to the unique shape of the robot, ASE can travel across land, dessert, swamp or even water by itself, or be casted by other devices (e.g. slingshot) to the mission area. ASE has a motion-sensing system based on Inertial Measurement Unit (IMU) and rotary magnetic encoder, which allows the internal controller to adjust its speed and attitude properly. The well-designed control system makes the robot free of visible wobbliness when it is taking actions like acceleration, deceleration, turning and rest. ASE is also a platform for research on control system design. The parameters of the internal controller can be assigned by an external control panel in computer based on MATLAB Graphic User Interface (GUI) which communicates with the robot via a WiFi network generated by the robot. The response of the robot can be recorded and sent back to the control panel for further analysis. This project is completely open-sourced. People who are interested in the robot can continue this project for more interesting features, such as adding camera for real-time surveillance, or controller design based on machine learning.
