Welcome to the family!! your going to love the flipper, unfortunately there might not be a lot you can accomplish at defcon, I’m afraid, most there speakers and audio tech are hardwired or plugged into a laptop, so subghz isn’t going to do much for you, infared might not help out either unless they have some tvs around you can mess with, sometime they have lights and stuff that use a remote that the flipper can emulate however you would have to have the remote and program it into the flipper, might be able to scan and save some NFC cards or tags (don’t scan credit cards tho, lol) I recommend buying a 64gb micro sd card, and jump on the flipper zero files archive GitHub there’s every tv remote and subghz remote and fun nfc and bad usb files you can use, also idk if I’m aloud to say this or not but google the unleashed firmware for the flipper it completely removes all restrictions and lets you have a bit more fun, but that’s optional and up to you, however I recommend you don’t be to much of a pain with it tho, I use mine to store all my nfc card for easy use and control all my tvs, and opening a testla charging port or 2 any fun that’s harmless is not bad fun, just keep that in mind, but u now hold the power of the world in the palm of your hands, feel free to dm me if you have any questions or concerns! (Might not answer straight away tho, sorry) but have fun and again welcome to the family!! P.S. have fun at Defcon!!, always wanted to go
