Team Frozen Voltage

Our FREE PCB Design & Etching Workshop(Batch 2k24) has officially come to an end, and what an incredible journey it has been!

Over the past few weeks, we explored the fundamentals of PCB design, got our hands dirty with the DIY etching process, and brought ideas to life through real, working projects. None of this would have been possible without the dedication, curiosity, and enthusiasm of our amazing participants.

A big thank you to everyone who joined us and made this experience so engaging and meaningful. We hope this is just the beginning of your journey into electronics and innovation.

Keep building, keep learning, and keep creating! 🚀

Appreciation to Promit Kumar Saha , one of our participants, for the sincere effort and active involvement in the PCB Design & Etching Workshop.

This circuit is designed for monitoring the battery charging process.

Huge appreciation to Batch 2K24, the participants of the PCB Design & Etching Workshop, for your enthusiasm and active participation so far!

Your interest and dedication are making the workshop engaging and enjoyable.
Let’s keep the momentum going—more learning and hands-on work ahead! 🚀

Hello, everyone!
We present our recent work on ECG Monitoring.

This is a low cost ECG monitoring device which uses a combination of ESP32 , AD8232 ECG Sensor Module in a small breadboard. With the help of 3 electrodes, our project shows heart rate could be measured at low cost and real time, easy. We also built a streamlit dashboard, train a small Machine learning model for predicting anomalies such as Bradycardia, Tachycardia etc. (on synthetic data). We also built a nice real-time dashboard for visualization.

Here's a live demo of our project dashboard: https://ecgmonitor.streamlit.app/

Let's connect with on GitHub: https://github.com/frovolts/ECG_Monitor

The RC Plane Subteam, consisting of Hafizur (MTE-21), Shahriar Kamal (EEE-22), and Shabique (EEE-22), has successfully built and tested another prototype. Although the flight ended in a crash, it marked a vital step forward in our progress.
