Aug 20, 2026 · 1h 9m

Summary

Elisio and Christopher White interview Kevin Santo Caputo, founder of Arctuthus Flux, about his Jumperless breadboard. This device replaces physical jumper wires with software-controlled analog crossbar switches and 445 LEDs to visualize connections. They discuss its use for prototyping, educational benefits for dyslexic users, and scripting capabilities via MicroPython. Caputo also previews the upcoming Barnacle Board, a modular system allowing seamless transitions from breadboarding to permanent PCBs.
