Micronucleus and Arduino payload workflow
The writeup documents Micronucleus flashing, Arduino IDE 1.6.x setup, Digistump board support, DigiKeyboard payload examples, and operating-system keyboard-layout caveats.

ATTiny85 USB HID injector
The badge used a Watterott Wattuino Nanite 85 / ATTiny85 USB-stick style board to act as a programmable USB keyboard injector.

note
The writeup warns that uploaded payload code can immediately run as USB keyboard input and recommends using a separate rescue/test computer, with macOS keyboard-layout handling also caveated.
The record treats the badge as a teaching artifact for keystroke injection and preserves operational risks instead of presenting it as a harmless novelty.
H2HC 2017 Badge
note
No local H2HC 2017 badge image has been added because the public writeup photos are not paired with an explicit reusable image license, attribution requirements, and processing provenance for catalogue publication.
The record stays source-backed and image-free rather than copying blog images or using generated badge art.
