## Summary

Hackaday editors Mike Szczys and Elliot Williams discuss several hardware hacks, including Michael Moulet's creation of a playable 'choose your own adventure' video game embedded within an OpenType font file. They also cover Andre Henchel's project to replace Amazon Echo firmware with open-source software to process voice commands locally, and Dan Foyzy's use of 100 ultrasonic transducers and FPGAs to steer a Styrofoam bead in 3D space. Additionally, the episode highlights Adam Boxstrom's modification of hobby servos with custom position sensors for high-precision robotics and Integza's 3D-printed ceramic rocket nozzles.
