The Build
The brain of the Key-Board is an Arduino Uno, which reads values from capacitive sensors and outputs square tones to the speakers. All the electronics and keys are mounted on a body constructed from wood. Pictured above is the SolidWorks model I created to help me design the body.
Funny enough, I used a lot of the knowledge gained from this project for a co-op position. At wonderMakr, one of my tasks involved designing and building technology for a capacitive-touch organ played on cucumbers. Right up my alley! Of course, I made many design changes to ensure the cucumber organ was as robust as possible. You can read more about the cucumber organ and wonderMakr here.
Looking back on this project, there's a lot I would do differently given the experience I have now (better sound and improved noise filtering for sensor readings, to name a few). A lot of these improvements were implemented for the cucumber organ I did at wonderMakr. I never expected to apply my Piano Key-Board project to a real world job, but I guess it just goes to show that taking the initiative to do things on your own does pay off sometimes.
