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.
