Good news, acolytes: the Great Old One whispers again.

Cult of Cthulhu is a puzzle badge from DEF CON 34, and v2 is the second run. Preorders open this holiday season. Sign up at pfarrsidetech.com to hear about the drop first.

Hardware: ESP32-S3, USB-C, rechargeable Li-Po, plus new SAO integration, two buttons, and faceplate mounts.

What’s new in v2:

-A faceplate that diffuses the LEDs and protects the screen
-Programmable SAOs whose LEDs sync with the badge’s display, with brightness and animation set from the badge
-Single-player séance and battle modes
-Two buttons on the back, keeping the front clear for the artwork

v2 firmware runs on v1 badges, and all v1 unlock codes still work. Codes are available by solving challenges on my site.
