Transformed Display Turns Video Chat into a Cost-Effective Walkie-Talkie
Check Out This Cheap and Impressive DIY Two-Way Video Walkie Talkie!
You've probably seen some amazing projects powered by ESP32 microprocessors, but have you ever stumbled upon a video walkie talkie like [Jonathan R]'s? It's a pair of devices that let you share both video and audio communications. And the best part? It's remarkably affordable!
This ingenious creation employs not one but two ESP32s: an ESP32-S3-based camera module, and a classic Tensilica ESP32 screen module. This setup offers an interesting comparison since one device features a Cheap Yellow Display board, while the other sports an Elecrow equivalent. The audio communications utilize ESP-NOW, while the video transmits over WiFi. Due to the mediocre audio amplifiers built into the devices, a small amp module is added to boost the sound.
Curious about the details? Check out the video below, which covers the design decisions behind this innovative project, along with a live demonstration. Although there's a slight lag, it's nothing too obnoxious considering the device's budget-friendly nature. So, could we finally be seeing the long-awaited video phone era take off?
Building Your Own Two-Way Video Walkie Talkie
Here's a quick run-down of the key components and design choices you'll need to consider for a successful DIY two-way video walkie talkie:
Key Components:1. ESP32 Microprocessors: The heart and soul of this device. These microprocessors handle the communication and control logic, offering Wi-Fi, Bluetooth, and more for both audio and video transmission [2][3].2. Video Modules: At least two video modules are required for this project: - Camera Module: Captures video using an ESP32-S3-based camera module [2]. - Display Module: A screen module that displays the received video, possibly controlled by another ESP32 [2].3. Audio Components: - I2S Microphone: For crisp audio input. - I2S Audio Amplifier: Boosts the audio output [1].4. Power Supply: Rechargeable battery pack for portability.5. Communication Hardware: Additional RF modules or antennas for better range and reliable video transmission [4].
Design Choices:- Modular Design: Makes maintenance and upgrades easier.- I2S Interface Utilization: Efficient for both audio and data-intensive applications like LED control [2].- Custom PCB: Integrates components efficiently and reduces size and power consumption.- Power Management: Key for extending battery life and ensuring consistent operation [5].
Implementation:- Software Development: Develop software for real-time video transmission over the chosen communication protocol.- User Interface: Create an intuitive interface for easy video and audio interaction.
Customizing a DIY two-way video walkie talkie using ESP32 may require specific adjustments based on exact requirements and component availability, but this foundation should set you on track for a successful project.
