In this episode, Milos upgrades his open-source PlatypusBot into Perry the PlatypusBot, transforming a simple Arduino-based rover into a full ROS2-powered robotics platform. He explains how the motor encoders work, implements PID control for precise movement, and connects an Arduino Uno R4 WiFi to a Raspberry Pi 4B running ROS2 Humble for real-time command and control. With a 3D-printed fedora and a name inspired by community feedback, Perry now moves, turns, and responds to ROS commands, laying the groundwork for future additions like sensors, LIDAR, and SLAM: bit.ly/4hXD40Z

![Reflex Training Machine Build - Using Relays, Transistors & Arduino
In this video, Mark builds a reaction-based catch game inspired by a classic TV challenge, using an Arduino Nano, relay-driven actuators, and a simple but effective control system. The setup drops sticks at random intervals, testing reflexes while showcasing practical electronics design, from power regulation and PCB assembly to embedded programming and mechanical integration. This project balances accessibility with clever implementation, making it ideal for makers looking to build something interactive and fun, you can find the supporting code on the element14 community: https://bit.ly/4dBqWRE

![DIY RF Modulator + Raspberry Pi Pico = Retro Gaming!
Andy takes a 1987 Sony Watchman portable CRT TV and transforms it into a working retro arcade system—without modifying the TV itself. Using a Raspberry Pi Pico, custom NTSC video generation, a hand-built RF modulator, and an Atari joystick, he codes an original Space Invaders–style game that broadcasts wirelessly to the Watchman. Along the way, he tackles composite video generation from scratch, resistor ladder DAC design, precise timing with PIO and DMA, and building RF circuitry from a 1985 magazine schematic.
