New tech podcast episode reveals wild engineering projects and a mystery sound

The latest episode of the popular tech podcast has dropped, packed with creative projects and deep dives into engineering topics. Listeners can explore everything from a beehive-inspired desk to a mystery sound challenge—all available in DRM-free MP3 format. Meanwhile, excitement builds for OMG Supercon, where the official badge has just been unveiled.

The episode kicked off with two Tinkercad projects, showcasing simple yet clever designs. A handheld PC build took centre stage, demonstrating how compact computing can be. The team also tackled the future of removable batteries, a topic that has since seen major real-world progress—from EU rules on smartphone battery replacement to CATL's sodium-ion modules for commercial vehicles.

A POV globe was modified to hover using multiple motors, blending art with engineering. The Component Abuse Challenge, sponsored by DigiKey, made a return, with contestants pushing a transmission line to extreme voltage levels. The show also revisited the history of movable type and featured an unusual desk that mimics the activity of a beehive.

For a lighter moment, the hosts challenged listeners to identify a mystery sound. The episode wrapped up with reminders about the 2025 challenge and a teaser for OMG Supercon, where attendees will get their hands on the newly revealed badge.

The podcast blends hands-on projects with forward-looking discussions, now even more relevant as battery tech and EU regulations evolve. Fans can download the episode freely and start preparing for OMG Supercon, where the latest badge design awaits. The 2025 Component Abuse Challenge remains open, with DigiKey backing inventive—and destructive—experiments.
