The core of this project is a hardware and firmware solution that allows video recording while fishing.

INTRODUCTION

A hardware and firmware solution enabling real-time video recording and monitoring during fishing trips, using a tablet connected to a 20-meter wired analog camera.

Fishermen use this tablet-camera setup to explore underwater environments, identify optimal fishing spots, and record footage. The camera streams live video to the tablet and supports navigation via magnetometer.

SOLUTION

Iomico reviewed and suggested PCB enhancements, developed a QT GUI, developed firmware for the camera and magnetometer, and updated the Embedded Linux OS to support stable video streaming and recording.

RESPONSIBILITIES

• Reviewed and optimized PCB design

• Developed a QT application based on detailed Figma wireframes

• Updated OS build and integrated necessary drivers

• Implemented video streaming, photo capture, and navigation firmware

• Coordinated UI adjustments due to hardware changes.

TECHNICAL DETAILS

• QT application with custom UI logic, responsive to hardware button layouts

• OS improvements for splash screen to video stream transition (handled buffer offsets, framebuffer processing)

• Custom drivers and codecs for n5/n12 streaming

• Magnetometer integration for navigation display

• Manual firmware deployment due to a lack of internet connectivity on the device.

CONCLUSION

This project highlighted the importance of conducting early investigations into video streaming technologies and maintaining close coordination with hardware vendors. Clear documentation and seamless collaboration between hardware, firmware, and UI teams were critical to success.
