Hackaday Podcast 125: Linux Users Talking Windows 11, Pop Bottle Filament, Old Phones with Modern Guts, and Eavesdropping in RF

Hackaday editors Mike Szczys and Elliot Williams look through the most interesting hacks of the week. We spent ample time in adulation of the automatons built by François Junod; wizard-level watchmaking wrapped in endless levels of artistic detail. A couple projects stuffed into old cellphones turned Elliot’s head. We got to see what happens if you spin a gear’s teeth on two axes to make a universal spherical gear. And we conclude the episode with a look at how Windows 11 may send a lot of good hardware to recycle center, and at how toothpaste tubes sometimes miss the recycling center completely.
