Virtual Badge
The virtual badge can be accessed here: https://badge.bsidesperth.com.au/
The code for the Virtual Badge code can be found in this repository under "VirtualBadge".
The virtual badge does not support "Online Challenges", but does contain hidden features such as a second episode, cheats, and an easter egg.
The virtual badge now supports keyboard inputs. The four buttons are mapped to W [Up], S [Down], A [Left/A], and D [Right/B]. Once a keyboard input is used, the symbols used in the sequence game change to U = UP, D = DOWN, L = LEFT, R = RIGHT. Thanks again to Matt for the suggestion and the code snippet for this feature.
Physical Badge Code Template
There is a basic template for an Arduino program under the folder "Template". The template demonstrates basic use of the LCD screen, ESP32, and button inputs. The download instructions can be found here.
Virtual Badge Server (API for Online Challenges)
Code for the Virtual Badge Server (API for Online Challenges) will be made available ~1st November 2025.
Badge Holder (3D Print)
A badge holder can be 3D printed using an off-the-shelf 3D printer. Recommended print settings are PLA plastic, 60+% infill, 40mm/s print speed. Some stringing may occur if filament is damp and/or print speed is too high.
Customisation
Customisation of the virtual and physical badge are both possible. Extra details can be found here
Known Issues
- To play the Online Challenges on a ESP32 supplied in a component pack, a re-download of the physical badge code to the ESP32 is required. [Fixed]
- Online Challenges were unavailable (18th Oct) due to firewall issue. This has since been resolved. [Fixed]
- Offline Challenges now generates sequences which use all four buttons (only three buttons were being used in the original code). [Fixed]

Questions
How big is the Bsides perth 2025 PCB?
It measures 68.7 × 100 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Bsides perth 2025 use?
15 parts, built around the ESP32-DEVKITM-1. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Bsides perth 2025 KiCad files?
From the badges4dotcom/bsidesperth2025badge repository on GitHub, at the commit this page was made from: the board is PCBDesign/bsides_perth_2025/bsides_perth_2025.kicad_pcb and its schematic PCBDesign/bsides_perth_2025/bsides_perth_2025.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Bsides perth 2025 design in my own project?
Its repository states no licence, so its author keeps all rights: ask badges4dotcom before reusing the design.
