## Problem
Stationary solar panels do not produce the maximum amount of energy possible at all hours of daylight. Setting up stationary solar panels requires an optimum angle to be found as well as lined up to the sun's path in the sky.
## Solution
Our solution to maximize energy production is for a sun tracking solar panel. The panel will move to face all directions to be perpendicular with the sun. It will use photoresistors to find the sun’s position and servo motors to move the panel.
## Solution Components
### Photoresistors
Multiple photoresistors will be behind the solar panel. When the photoresistors are completely shaded, the panel will be perpendicular to the sun. So the photoresistors will detect which have the most light on them and move correspondingly to minimize light on all of the photoresistors.
### Servos
One servo will rotate the whole device on an axis parallel to the ground and another will rotate it on an axis perpendicular to the ground allowing.
### Power Tracking
It will have real time output of the power generated by the solar panels. It will log the power output in order to graph the results of the power. It will also have a real time output and log of the power consumed by the whole system.
### Manual Controls
For only the first time setup of the device, it will have a button to take over manual control of the panel to roughly(not necessary to be accurate) face it where the sun will be in the morning.
### Nighttime Reset
Using the power tracking, it will look for a major drop in power, AKA when the sun goes down. It will do a 180° turn and then turn off the servos. It will then turn them back once power is high enough, AKA the sun is up.
# Criterion for Success
Our solution will track the sun anywhere in the sky and rotate the panel to face it. It should produce more energy than a panel which is stationary. Currently Zomeworks has a solar tracking panel which only rotates on one axis and requires it to be set up at a specific angle depending on its location in the world. Our panel will rotate on two, allowing it to face the sun in any location in the sky, removing the need for much setup.

Assistive Chessboard

Featured Project

Problem: It can be difficult for a new player to learn chess, especially if they have no one to play with. They would have to resort to online guides which can be distracting when playing with a real board. If they have no one to play with, they would again have to resort to online games which just don't have the same feel as real boards.

Proposal: We plan to create an assistive chess board. The board will have the following features:

-The board will be able to suggest a move by lighting up the square of the move-to space and square under the piece to move.

-The board will light up valid moves when a piece is picked up and flash the placed square if it is invalid.

-We will include a chess clock for timed play with stop buttons for players to signal the end of their turn.

-The player(s) will be able to select different standard time set-ups and preferences for the help displayed by the board.

Implementation Details: The board lights will be an RGB LED under each square of the board. Each chess piece will have a magnetic base which can be detected by a magnetic field sensor under each square. Each piece will have a different strength magnet inside it to ID which piece is what (ie. 6 different magnet sizes for the 6 different types of pieces). Black and white pieces will be distinguished by the polarity of the magnets. The strength and polarity will be read by the same magnetic field sensor under each square. The lights will have different colors for the different piece that it is representing as well as for different signals (ie. An invalid move will flash red).

The chess clock will consist of a 7-segment display in the form of (h:mm:ss) and there will be 2 stop buttons, one for each side, to signal when a player’s turn is over. A third button will be featured near the clock to act as a reset button. The combination of the two stop switches and reset button will be used to select the time mode for the clock. Each side of the board will also have a two toggle-able buttons or switches to control whether move help or suggested moves should be enabled on that side of the board. The state of the decision will be shown by a lit or unlit LED light near the relevant switch.
