The Platypus Bot- a budget-friendly robot inspired by the TurtleBot3- gets a test drive my Milos! He used 3D-printed parts, common hardware, and a drill battery for power and scavenged parts from a broken robot Vacuum! What do you think??

![ESP32 Chest Strap Heart Rate Sensor | DIY Fitness Project
Follow Milos as he builds a DIY ECG based heart rate chest strap using an AD8232 module and an ESP32 C3, then tests it during a real run to compare its performance with common fitness tracking gear. He walks through the signal capture process, explains how the Pan Tompkins algorithm detects heartbeats and shows how the device streams data to a phone over BLE just like a commercial sensor. The project explores what works, where the readings drift and what he plans to improve in the next version: https://bit.ly/48BOmEW

![Build Your Own 3D Printed Pulse Induction Metal Detector
In this video, Mark Donners takes you through the full build of a DIY pulse induction metal detector and explains the principles behind how it detects metal. He covers the electronics design, coil winding and shielding, and how an ESP32 is used to generate pulses, analyse the return signal, and provide audio and visual feedback. The project is designed to be adjustable and extensible, allowing you to tune detection behavior and explore how different parameters affect performance. Mark also shares practical insights from building and testing the detector, making the video useful for anyone interested in metal detection or hands-on electronics: https://bit.ly/49niZ05

![How I Built a Giant LED Snowflake Using LED Filament (Circuit Sculpture Tutorial)
Natasha (@TechnoChic) builds a free standing LED snowflake using LED filament, exploring how to shape, wire, and solder a layered circuit sculpture from scratch. From planning segmented control to handling fragile components, this project walks through the full process and what she learned along the way.

![Animating LEDs with a micro:bit
In this video, Natasha continues her LED snowflake circuit sculpture by connecting it to a micro:bit and bringing it to life with animation and sound interaction. She walks through how the LED filament groups are mapped to pins, how early animation ideas evolved once everything was powered up, and how she had to rethink her approach after running into the micro:bit’s analog pin limitations. Along the way, she shares practical build decisions, small problems that nearly derailed the project, and why switching from smooth fades to bold digital animation actually made the final result stronger. The finished snowflake reacts to sound using the micro:bit’s built‑in microphone and sits somewhere between a piece of art, a toy, and a display, and you can also follow along and find the products used on the element14 community: https://bit.ly/3Rr6ivR
