VisualiMU

The VisualiMU Physics Visualizer

Inspiration

We were inspired by the challenges we faced in our high school and college physics classes. We believed there was a better way to understand the complex topics in physics and strove to build a solution.

What it does

Displays a dynamic free-body diagram on a website that is controlled by the user's movement of a device to better visualize and understand mechanics concepts.

How we built it

Used an ESP32 and an accelerometer to track acceleration data and transmit it through Bluetooth to a web server. Used this to calculate force values in 3-dimensions and display a dynamic diagram on the website.

Challenges we ran into

We had some issues programming the firmware for the ESP32 and getting the accurate ADC data to output via Bluetooth. However, we were able to resolve this after various methods of troubleshooting.

Accomplishments that we're proud of

We are proud that we were able to make a finished product without bugs, including a 3D printed housing case, within the short time frame.

What we learned

We became more familiar with the ESP32 microcontroller, as well as Bluetooth/WiFi communication protocols.

What's next for VisualiMU

We hope to expand the capabilities of our device to visualize more physics concepts (oscillations, magnetic fields, kinematics, etc.). We were limited in our parts selection, and believe that if we are able to get access to more sensors, we can retrieve more data and present useful information.
