  Arduino, sensor, and can drumset

Inspiration

Interest in the dynamics of neural network weight updates in supervised classification

What it does

Maps weights to frequencies within a 7-octave spectrum, and allows the user to modulate the periods of those frequencies by placing their hand a certain distance from a sensor. Periods decrease closer to the sensor, and increase farther away. A servo and a can are used as a makeshift drumset.

How we built it

Arduino neural net, made with the NeuralDuino link library. Functions that update and print weights were modified to play a tone and modulate it with the sensor.

Challenges we ran into

We initially set out to implement a Physical Neural Net, in circuitry and software. We found that we did not have the tools or knowledge of physics to fulfill this goal, so we used the existing model we had built to make music.

Accomplishments that we're proud of

How dynamic the sensor modulation is - it's essentially a theremin.

What we learned

A lot of the physics and math of electromagnetism

What's next for MuNet

All sorts of modulation (the goal is a real synthesizer), and making the net create music by more than just updating weights (initialization of activation function, etc).
