LayerOne
The May 24-25, 2025 LayerOne Pasadena edition whose official event and Hardware Hacking Village pages documented electronic-badge ticketing, HHV badge support, and the GLiTCh BadgE hardware-hacking platform.

LayerOne 2025's GLiTCh BadgE was a conference electronic badge and hardware-hacking platform centered on an RP2040, iCE40 FPGA, voltage glitching, crowbar control, SWD, AVRISP, analog monitoring, multiple USB modes, and CLI-driven experiments.
Lifecycle
DAP mode presents the badge as a CMSIS-DAP probe for pyOCD, OpenOCD, Keil, and SWD target debugging while keeping a CLI serial interface available.
LayerOne's HHV challenge list tied the badge to Open Sauce badge work, ESP32 BluTag JTAG, RP2040 timing-attack exercises, and a custom shadetree companion-hardware target.
The badge docs expose voltage-glitch and crowbar controls, setup commands, trigger workflows, and target-voltage tuning through the GLiTCh BadgE CLI.
The README describes ADC streaming over a serial interface and frames the badge as a basic 12-bit logic analyser for low-rate signal inspection.
The hardware-hacking guide documents AVRISP wiring and commands for initialization, target identification, flash reads/programming, and fuse access.
Operational history
Hardware and firmware features are kept to repeatedly corroborated repository and guide statements instead of overstating uncertain generated prose.
The record presents the badge as a real hardware lab platform with documented errata rather than a polished reference design without caveats.
The entry remains source-backed and image-free rather than reusing generated, teaser, attachment, screenshot, or undocumented badge imagery.
