Introduction:
The marvels of ChatGPT are no secret, showcasing the incredible power of natural language processing. In our quest for innovation, we delved into experiments and proudly presented the ChatGPT Terminal — a portable, user-friendly GPT machine. This device seamlessly incorporates ChatGPT, enabling you to ask questions, seek answers, or request code snippets effortlessly.
How it Works:
The heart of the ChatGPT Terminal lies in the ESP32 microcontroller (MCU), which acts as the brain orchestrating communication between the user and ChatGPT. Connected to the ESP32 is a PS/2 keyboard for input, offering a familiar typing experience. The result is then displayed on an 8.9cm TFT screen, creating an interactive and intuitive user interface.
The Process:
- User Input: Simply connect a PS/2 keyboard to the ESP32 MCU.
- Query Display: The terminal assists by showcasing the user’s query on the TFT screen.
- Communication with ChatGPT: The ESP32 sends the query to ChatGPT over the internet using a Wi-Fi connection.
- Output Reproduction: The output obtained from ChatGPT is seamlessly reproduced on the TFT screen.
Key Features:
- Portability: The ChatGPT Terminal eliminates the need for an elaborate computer, offering a compact solution for on-the-go interactions with ChatGPT.
- Easy Connectivity: With a PS/2 keyboard and an ESP32 MCU, the terminal ensures a hassle-free user experience.
- TFT Display: The 8.9cm TFT screen provides a clear and concise presentation of the user’s queries and ChatGPT’s responses.
- Minimal Hardware Requirements: The Bill of Materials (BOM) is simple, comprising an ESP32 MCU, PS2 keyboard, 8.9cm TFT, and basic electronic components
