Special Circuit :: ECE 445 - Senior Design Laboratory

Special Circuit

A student whose Senior Thesis Project (ECE 499) does not involve the design and construction or testing of electronic devices or hardware is required to complete a Special Circuit Project in the ECE 445 lab during the semester they take ECE 499. In addition, students enrolled in ECE 445 who are not undertaking a hardware dominant project are required to complete the special circuit (although this is strongly discouraged and the course staff will work with your team to make sure you have enough hardware in your project to avoid having to complete the special circuit.)

The special circuit is typically posted in the middle of the semester. Once you sign up for the special circuit (see below), you will be assigned a TA, a locker, and a special circuit which generally takes about 12-15 hours to complete. When you have it designed and built, you will give a functional demonstration to your TA, who will then inform the professor who will inform undergraduate advising that your task is complete. You are NOT required to attend any of the classes, reviews, demos, or presentations associate with the ECE 445 class.

Sign up for Spring 2020 is now open

Sign up for the Special Circuit assignment on the Lab Access page. Instructions for completing the special circuit will then be provided in the near future. Please check this page for updates.

Assistive Chessboard

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.
