Andy Geppert's passion for magnetic core memory lead him to create the Core64 -- an interactive 64-bit woven memory array that doubles as a touch screen thanks to the clever addition of RGB LEDs and a magnetic stylus.
In his Supercon 2022 talk, Andy goes over the hows and whys of core memory, a staple of 60s and 70s computers that was perhaps most famously used on the Apollo spacecraft. He'll also explain the origins of his Core64 project, and how he's managed to turn this antiquated computer storage technology into an engaging gadget for users both young and old.

![Supercon 2022: Alec Vercruysse Can See Through Murky Water
Detecting objects underwater isnt an easy challenge, especially when things get murky and dark. Radio waves dont propagate well, so most techniques rely on sound. Sonar is itself farily simple, simply send out a ping and listen for an echo, and that will tell you how far something is. Imaging underwater is significantly harder, because you would additionally need to know where each echo is coming from.
To answer the question of whether it is possible to put together an ultrasonic 3D imager that would cheaply enable anyone to image objects underwater, [Alec Vercruysse] and fellow team members at the Harvey Mudd College set out to create a system that does exactly that.
