Notes for 2026-10-19.

New Assignments

New assignment, due Mon Oct 26: Exercise: Automatic Puzzle. Please have the device ready to demo in class and submit documentation to Assignment 7 Shared Folder.

Note: I highly recommend designing the 3D printed part right away and getting it in the print queue as soon as possible. I’d be happy to review any sample design, please just put your STL file in the shared folder and send me an email.
