## Summary

Hackaday editors Mike Szczys and Elliot Williams review a week of hardware hacks, including a tentacle robot by Ivo DeHas that uses Bowden cables for both actuation and sensing, and a cubic Raspberry Pi cyberdeck by EKG. They also discuss a project by HP Friedrichs that refines black sand to create homebrew inductor cores, and a plastic wrap kayak built by the SG 19.3 group. The episode concludes with a discussion on GitHub's removal of password authentication in favor of SSH keys and GPG keys.
