CactusCon
The September 29-30, 2017 Arizona hacker and security conference edition whose public attendee writeup preserves a soldered Wi-Fi/Bluetooth scanner badge built around a WemOS board.
Phoenix Convention Center, Phoenix, Arizona · United States · 2017
The CactusCon 2017 badge is preserved through a first-hand attendee writeup that describes paying for the badge package, soldering and troubleshooting the board at the Phoenix-area event, and using it as a tiny Wi-Fi and Bluetooth scanner.
Lifecycle
The writeup says the badge's first screen scrolled Bluetooth device MAC addresses.
After troubleshooting, the badge displayed visible Wi-Fi SSIDs and signal strength in the attendee writeup.
The writeup identifies the badge as a tiny Wi-Fi and Bluetooth scanner made from a WemOS board.
The attendee writeup says CactusCon 2017 could be attended free or with a $45 package that included a badge, shirt, and swag.
Operational history
The entry remains source-backed and image-free rather than copying blog photos, screenshots, social media, or generated media.
The record uses WemOS only as the source-backed board family reference and avoids pinout, controller, or firmware-specific claims.
The catalogue records the real scanner badge while keeping technical claims limited to the public attendee writeup.
