ATTiny85 USB HID injector badge
A small H2HC 2017 badge built around an ATTiny85 USB-stick module for USB HID keyboard-injector experiments, Micronucleus bootloader flashing, and Arduino IDE workshop-style payload development.

Publisher of the H2HC 2017 badge hardware and USB HID payload writeup.
SourceThe writeup identifies the H2HC 2017 badge board as based on Watterott's Wattuino Nanite 85 design and says Watterott manufactured the badges.
SourceIt fills a Brazilian H2HC lineage gap between the 2013 ARM development badge and the later 2018 ESP32 art badge, showing a simpler USB-attack teaching artifact in the middle of the series.
The Security-Bits writeup describes a badge made from two PCBs: a white baseplate and a USB-stick PCB based on Watterott's Wattuino Nanite 85. It used an ATTiny85 compatible with Digispark workflows, USB connection through the badge board, and serial-adapter soldering pads for bootloader recovery.
The badge used Micronucleus bootloader behavior and Arduino IDE 1.6.x / Digistump setup. The writeup documents DigiKeyboard-style USB HID payloads, Windows key-delay handling, macOS keyboard-layout caveats, and a recommendation to use a dedicated rescue/test computer because uploaded code can immediately run as keystrokes.
The badge is presented as an early USB HID injector exercise: not a general-purpose electronic art badge, but a conference artifact that teaches attendees how tiny USB devices can automate keystrokes.
Lifecycle
The writeup documents Micronucleus flashing, Arduino IDE 1.6.x setup, Digistump board support, DigiKeyboard payload examples, and operating-system keyboard-layout caveats.
SourceThe badge used a Watterott Wattuino Nanite 85 / ATTiny85 USB-stick style board to act as a programmable USB keyboard injector.
SourceThe artifact consisted of a white baseplate PCB and a separate USB-stick badge board, with soldering-pad access for serial-adapter bootloader repair.
SourceOperational history
The record treats the badge as a teaching artifact for keystroke injection and preserves operational risks instead of presenting it as a harmless novelty.
The record stays source-backed and image-free rather than copying blog images or using generated badge art.
