Some fun mini battery versions of BLE CTF I’m playing with.

Lol, I totally forgot about the name switch up that year 🤣

I saw a student in my workshop today who had a custom BLE CTF chip in his DEF CON badge! So cool! I got a picture but I can’t make out the full name of the creator. Zer0vul something. Love it 😍.

Trying something new with my DEF CON BLE hacking workshop prep this year! Going to be fun! 🤞
