DEF CON 32’s badge segment features Ryan (F Cactus) of Make It Hack In showing several homebrew badges — an interactive SAO that exchanges signals with other badges, Star Trek‑themed SEOs, and a “Hacker Summer Camp” soldering kit. He also demoed a Flipboard add‑on to turn a Flipper Zero into a wearable macro pad that can send keystrokes, sub‑GHz and IR transmissions; he credits a collaborator for the software tutorials. He praised Mar’s injection‑molded, translucent official badge and traced his interest back to DEF CON 24.
