This week Hackaday Editors Elliot Williams and Tom Nardi start things off with updates on the rapidly approaching Hackaday Europe and the saga of everyone’s favorite 3D printed boat.

From there they’ll cover an impressive method of seeing the world via WiFi, Amazon’s latest changes to the Kindle ecosystem, and an alternate reality in which USB didn’t take over the peripheral world. You’ll also hear about a multi-level hack that brings the joys of Linux into the world of Animal Crossing, 3D printed circuit components, and the imminent release of KiCAD 9.

Stick around until the end to learn about a unique hardened glass from East Germany and the disappointing reality of modern voice control systems.
