In this episode of Workbench Wednesdays, James reviews the Multicomp Pro MP7110001, a four-channel linear bench power supply delivering over 340W of output. He walks through its key features, including a 4.3" display, digital I/O control, built-in serial and parallel channel switching, and user-defined presets. The video includes practical performance tests such as ripple voltage, turn-on skew, and maximum power output. James also notes the absence of remote sensing and shares insights into real-world usage. Watch the full review to see how this supply performs on the bench: bit.ly/44JAmri

![Make Your Own Vocoder with Teensy 4.0 - Voice of a Cylon?!
Join Mark as he builds a digital vocoder using a Teensy 4.0 and audio shield, demonstrating how audio spectrum data can be analyzed and used to reconstruct sound in real time. He walks through the full hardware setup, from soldering components on a prototyping board to wiring potentiometers and audio jacks, then dives into the software using the Teensy Audio System Design Tool. The result is a working vocoder capable of producing classic sci-fi effects like the Cylons from Battlestar Galactica: https://bit.ly/41uZUGb

![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.

![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
