How to Build a Physical Inbox with a Raspberry Pi and AI-Generated Code

Create a tangible connection with your online audience by building a thermal receipt printer that prints messages sent from a public webpage. This project uses an AI code editor to bridge the gap between software and hardware.

AI-first code editor

02Step-by-Step Guide
1

Brainstorm with an AI Code Editor

Start with a brain dump into an AI code editor like Cursor. Use a direct, outcome-focused prompt and let the AI interview you with clarifying questions to map out the entire plan.

Prompt:
I want to create a printer where anyone in the world can send me a message from a website, how best would I implement this? Let's brainstorm.
2

Generate a Hardware Shopping List

Once the concept is clear, ask the AI to generate a shopping list of the necessary hardware components, such as a mini thermal receipt printer and a Raspberry Pi.

3

Source and Verify Hardware

Purchase the components from your list. Crucially, triple-check the AI's suggestions before buying to ensure all parts are compatible and correct for your project.

Pro Tip: Always verify AI-suggested hardware for compatibility before purchasing to avoid errors.
4

Build the Web Interface and Backend

Create a public webpage with a simple form for users to input a message. When a user clicks 'print', the message is sent to a database (like Convex for logging) and to a service running on your Raspberry Pi.

5

Connect the Raspberry Pi and Printer

Set up the Raspberry Pi to run a service that listens for the incoming messages from your website. Connect the Raspberry Pi to the thermal printer via Bluetooth and write the code that triggers the print command.
