Add-on dossier
A linkable lifecycle record for hardware expansions, app ecosystems, firmware upgrades, cases, radio parts, and post-event badge experiments.
The project page describes an IoT Bluetooth mesh where badges connected over USB serial could join the conference network and remotely execute badge commands within the badge-game framing.
Badge context
Primary add-on source for the ATSAMD21G18A DOOM SAO, SAO v1.69bis logical integration, serial terminal, DOOM Guy interface, bus sniffers, virtual EEPROM identity, and DC27-badge compatibility context.
Secondary hands-on source corroborating the badge as a hardware-hacking tool, BMD-340/nRF52840 core, FT2232H dual-channel USB behavior, OLED/LED/light-pipe presentation, USB-C, SWD, JTAG, SPI, I2C, UART, and bit-bang workflows.
Primary log documenting the B.E.N.D.E.R. v2.0 challenge path, text-adventure framing, buffer-overflow step, firmware/hardware/radio/crypto/social areas, and post-event walkthrough status.
Primary debug-guide source for SWD/OpenOCD exploration through the onboard FTDI path and badge-as-debugger concept.
Primary hardware-guide source for the FT2232H channel split, `/dev/ttyUSB0` hardware-hacking channel, `/dev/ttyUSB1` embedded-terminal channel, and UART/JTAG/SPI/I2C/bit-bang usage intent.
Primary production source documenting Macrofab triage, serial failures, LED failures, capacitive-touch failures, flashing failures, BMD-340 soldering diagnosis, hot-air rework, and yield caveats.
Project-owner Hackaday.io source for DEF CON 27 context, BMD-340/nRF52840 hardware specs, IS31FL3741 lighting, capacitive touch, FT2232H, SWD/Tag-Connect, SAO 1.69bis, BOTNET, B.E.N.D.E.R., team roster, sponsors, and free-distribution framing.
Source trail
Secondary hands-on source for the hardware-hacking-tool framing, nRF52840/BMD-340 core, FT2232H dual-channel behavior, SWD/UART/JTAG/SPI/I2C/bit-bang workflows, USB-C, and lighting presentation.
Primary project-owner source for hardware specs, DEF CON 27 dates/venue context, badge functions, BOTNET serial setup, B.E.N.D.E.R. framing, FT2232H hardware-hacking role, team roster, sponsors, and free-distribution framing.
Primary add-on source for SAO 1.69bis integration, ATSAMD21G18A hardware, ST7789 display, USB-C, serial terminal, bus sniffers, virtual EEPROM identity, and DC27 badge interaction context.
Primary challenge source for the B.E.N.D.E.R. v2.0 walkthrough, embedded text adventure, buffer-overflow example, and multi-area hacking challenge design.
Primary hardware-guide source for the FT2232H channel split, hardware-hacking breakout purpose, and UART/JTAG/SPI/I2C/bit-banging workflows.
Primary production source for Macrofab triage, serial, LED, capacitive-touch and flashing failures, BMD-340 soldering diagnosis, and manual rework.
