## Summary

Kevin Santo Cappuccio, founder of Architeuthis Flux, discusses Jumperless, an open-source breadboard that replaces physical jumper wires with software-controlled analog crossbar switches and 445 RGB LEDs. He explains the device's architecture, including the Raspberry Pi Pico running MicroPython, the high-frequency performance of the switches, and the upcoming modular Barnacle Board. The conversation covers use cases in audio synthesis, education for dyslexic learners, and the challenges of manufacturing a luxury hardware product as a solo founder.
