The 2D printer pen is capable of printing a wide range of high-resolution images and designs directly onto beverages. These pens are intended to be used by cafes and restaurants to attract more customers.
This project aims to reach out to kids to enhance their learning. Before this project, there is no feature or functionality in the current app that converts speech to text. The team saw this as an opportunity for kids to be able to speak and to take that as input into the app and print it out. By doing this, they will be able to visually see the link between the word and the physical object. Below are more details on how the team achieved this.
| Component | Purpose |
|---|---|
| Raspberry Pi | Used to control all the electronic devices in the system |
| Nima17 DC motor | Move the Printpen back and forth to print on the food |
| L298N Motor Driver | Connected to the Raspberry Pi to drive the DC motor |
| Speaker | To sound out the word that is being printed letter by letter To indicate when to start speaking To sound an alarm before the motor starts |
| LED Screen | To display to the user what the machine is doing |
This product is meant to be used by children in childcare centers during their mealtime to enhance their learning.
For this project, every component was tested in isolation before putting it together. I worked on 2 components:
Simulating the keypresses on the app since the team was not given API access.
I wrote the Python code for the motor using a Raspberry Pi, integrated all the components, and streamlined the entire process flow.
