Inspiration

Doodling images or clicking pictures of notes on a whiteboard is so 20th century. It's time we move to more innovative methods to record handwritten patterns in an efficient and precise manner.

What it does

EpiPen captures all the patterns rendered by the resulting marker and transmits the data over Bluetooth to a client machine that plots and stores the captured information.

How I built it

We used an Arduino microcontroller and integrated it with an IMU, a Bluetooth module and an Optical Sensor. These controllers/modules are attached to a marker that an instructor uses while writing on a whiteboard. The hybrid setup is what we call an EpiPen.

Challenges I ran into

Setting up and connection and sending across data over Bluetooth. The frequencies over which the data was being communicated was not compatible with the recipient client.

Accomplishments that I'm proud of

The deltas for orientation and displacement captured by the Gyrometer and the Magnetometer to plot the exact location of the sensor.

What I learned

Arduino development, integrating circuit modules and making them communicate

What's next for EpiPen

Error correcting, Noice cancellation, Increased Precision, Releasing it as a product
