![Building an Autonomous LEGO Train with CircuitPython and LIDAR
Lorraine hacks a Bluetooth-controlled LEGO train in this week’s episode of element14 Presents, mounting a track system to the ceiling of her home. She integrates CircuitPython, a Seeed XIAO board, NeoPixels, and a spinning LIDAR sensor to detect walls and control the train’s movement. The video covers setup, track planning, component integration, and a ground-level test before moving the build to its final ceiling-mounted location. Watch to see how it performs and get the full build details, code, and parts list on the element14 Community: https://bit.ly/4eBeYHB

![Test Your Reactions 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

![Building a Wi-Fi Controlled Cookie Jar Using an ESP32 and Strava Data
Milos rebuilds his old Smart Cookie Jar project using modern parts, a compact 3D-printed locking mechanism, and an ESP32 connected to Strava. The jar stays locked until you complete your chosen running distance, turning your workout into a reward you actually have to earn. In the video he walks through the updated mechanism, the ESP32/Strava integration, and a real test run to prove it works—all while keeping the jar looking like an ordinary container of treats! https://bit.ly/4oRCJyx

![Upgrading My Electronics Workbench: Tools I Actually Use Every Day
In this episode, Clem walks through his new electronics workbench and explains why he chose each part of the setup, from the adjustable desk and fume extraction to power supplies, soldering, rework, and test equipment. We sent Multicomp Pro tools, selected by Clem for his upgrade. He shares what worked, what didn’t, and how real-world use shaped his decisions, with plenty of practical detail for makers and engineers planning their own bench upgrade: https://bit.ly/49L0u5Z
Disclosure: These Tools were provided by Multicomp Pro, a brand owned by Newark and Farnell (The team and company behind element14 Presents) all the of kit were selected by Clem and sent to him from our own warehouse.
