6 Automatic Trumpet Tuner

A large problem in any musician’s life is tuning. The tuning of an instrument changes every single time you take it out of the case, and even while playing. This can be detrimental at times, especially on longer notes where you can definitely tell whether one member of a band is out of tune or not.

Our project goal is to create an automatic tuner that is self-contained (battery operated), can be placed on the tuning slide, will automatically adjust the tuning based on the note you are playing, and has a simple enough interface to give the musician feedback on whether they are sharp, flat, or in-tune while the auto-tuner is turned on.

Major challenges to be overcome are interference from other sound sources, power delivery to the system using only batteries, using current and previously captured data to enhance the tuner’s accuracy, and researching motors (possibly a linear actuator) that will have enough force to push the slide in and out while still having a low power requirement.

As far as we know, a product like this has not yet been created for a trumpet, and could easily be adapted for other brass instruments that face similar issues.

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.
