What this episode covers

Hosts Elliot Williams and Al Williams discuss recent Hackaday posts, including a neural network that eavesdrops on keyboard typing via sound spectrograms and an STM32-based oscilloscope project by J.G. Piero. They explore industrial design techniques for 3D printing, such as shadow lines and crush ribs, and debate the relevance of home PCB etching versus commercial fabrication. The episode also covers Norbert Heinz's electrical discharge machining experiments, a magneto-hydrodynamic drive, and a review of the Beepy, a Raspberry Pi-based device featuring a genuine Blackberry keyboard.
