July 10th, 2025 – “Chapter 1: Designing Graphical Interface…”

[TactiFail]

Hello Hackers!

This month we are joined by @TactiFail who will be presenting his talk “Chapter 1: Designing Graphical Interface…”:

> Serial interfaces to conference badge challenges are almost a given at this point, and the badge from the recent SecretCon 3 in Minnesota was no exception. In this talk, Tacti will briefly cover the badge’s interactive challenge element, then go a bit into serial communications, and finally take a slight detour into Unity game development, ultimately leading to a demo of a quick and dirty 3D interface wrapper around the badge’s serial challenges.

> Bio: Tacti is the DC612 lead, but not POC in case any Defcon staff are reading this ;) He does infosec for a living, hacking for fun, and cooking because if he has to eat, it may as well taste good.

Meeting will be on Discord. If you need an invite, look no further: https://discord.gg/HYzJcfVGjH

Talk starts at 6:12 PM U.S. Central, but feel free to hop in early and chat.

P.S. Please note that there will be no meeting for August next month, as that is when Defcon proper occurs. We take that month off, as a lil treat.
