532: It's Still Real Fire

Kevin Santo Cappuccio, founder of Architeuthis Flux, joins the show to discuss creating Jumperless, an open-source breadboard that replaces physical jumper wires with software-controlled analog crossbar switches. We explore the need for 445 RGB LEDs on a breadboard, using MicroPython to create scriptable circuits, some of the lessons that can be implemented with the Jumperless, and how it might be used to create new instruments. Kevin also shares the story behind his upcoming Barnacle Board.
