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.

Growing Degree Day Monitor

Featured Project

The purpose is to create an inexpensive growing degree day monitor that records temperature and computes growing degree days for a specific farming field during a growing season. This monitor will be placed near a farm field where it will monitor temperature conditions during the growing season. It will record both the ambient air and soil temperatures over the course of day. These temperatures will then be used to calculate the growing degree days. The cumulative number of degree days will then be displayed on either a seven-segment display or this can be downloaded to a computer. This monitor will be powered through a combination of both solar and battery power.
