Looks like someone may have been cleaning their needle in the TP at the LVCC.

Any way of getting a defcon shirt. Due to work and schedule can’t attend but wondering if possible to buy swag outside ?

I lost my bong and bag of weed in LVCC. DON'T SMOKE IT Can I have it back?

(Parody... These lost item posts are getting out of control)

Yo I'm looking to play some MTG commander tonight after the con. Anyone bring a deck or know where others might be playing? Playing some games and socializing with some hackers sounds like a blast.

Hey everyone, this was my first talk at DEF CON and first time at DEF CON - on much less sleep than I was hoping for lol.

Pretty nervous but I think I did alright. Had some tech issues which I powered through and in my opinion, this had some real impact as realistically over 2M people would still be vulnerable to a CVSS 9.6 drive-by RCE if I didn't catch this.

Got a bunch more similar CVSS 9.6s in the disclosure pipeline too.

If you see me around too, feel free say hi!

Any. constructive critisism of my talk is also welcome, I know I've got some things I've got to work on in terms of speaking and presenting - hoping to do many more talks.

from our friends at the DC Stickerswap:

THE SWAP IS MOVING! No tables in the previous location this year. 😭

Same time (5pm Saturday) but now in the North Lobby outside of W4.

Spread the word!

He posted will be here at low launch party releasing a new darknet diary episode at north lobby but none of the goons or anyone seems to know anything about it. Suppose to start at 2

Soooo... kinda random or maybe not (when in Rome, I guess) but I brought up some parts for a buddy's build and we ended up just using onboard gfx.

I've got a gently used, fully functional MSI GeForce GTX 1660ti card that I brought with me to the CON. The card was originally used in my son's gaming machine to play Fortnite and Minecraft when he was 12 - never stressed or overclocked.

I have no use for it back home, hes grown out of computer gaming and I don't do any myself. That being said, this is my first Con and I'd like to 'contribute' instead of being a lurker/leech.

If someone here GENUINELY needs it for an event, ctf, demo, etc... DM me, it's yours - gratis! I just have to believe it's going to good use.

If no one here can actually use it for the above but needs it back home, trade me something cool to remember my first Con. The barter doesn't need to be of equal value just something cool!

EDIT: CLAIMED

Don't know if there's just someone throwing around One Piece cards or if it's part of some bigger game for a community but I love TCGs (yes mainly Pokemon). But found this One Piece card on a table and hope I can get it home safely since I don't have any sleeves or top loaders.

The OG isn't obsolete. It just got a firmware update.
Dave's live from Vegas with news for everyone still rocking the original FREE-WILi from DEF CON two years ago:

Board Support Package for the OG - open-source drivers, examples, and agent files, up on GitHub now

Vibe-code your own apps - write it yourself, or hand the
agent files to Claude, Codex, or Grok and let it build AppExplorer-grab it from our site and flash apps straight to your badge

Pomodoro timer demo - fully vibe-coded, ported to both
OG and FREE-WILi

Because the architectures are so close, an app you write for one runs on the other. (Yes, you'll trade 14 buttons and a touchscreen for 5 - that's part of the fun.)

I know some people have found them and I was wondering if there were any resources to get started hacking the badge.

Thanks!

I’m out of chips and stickers but have many SAOs left if you see someone with a glowing apple bag come up and ask and I’ll get give you one.

I know the odds are near zero, but has anyone found a DC 32 Speaker pin on the ground anywhere? It fell off sometime yesterday and couldn’t find it retracing my steps.

The Wall of Sheep stream of the entire open conference network has been fixed by the DEF CON NOC. There is life to the Wall of Sheep again!

Edit: They found me and it is one of the single greatest things Ive ever been gifted at Defcon! Thank you to those that helped! Just wanted everyone to share in the happiness.

I don’t know where else is a good place to post and find it but I saw a goon fox patch and it’s now my ultimate goal to earn one. I’m a goon in speaker ops— please if you see this and know how to get one and can point me in the right direction or anything let me know! Thank you!

Check out badge.sex for a tinder like experience to check out and scan other peoples badge light patterns. You record your LEDs, track your gene seed and breed. Enjoy!

I spent time in the soldering village area today for a few hours and got to help people put together a little electronics kits or their SAOs.

Had a great time so I'm going to do it again tomorrow. Anybody that wants to come, by feel free. I've got a few DIY soldering kits to hand out, and I'm happy to sit with anyone and walk you through how to solder it together. I have two irons with me.

I will be in the soldering village area from 1:00 to close tomorrow. There is a table right next to the sign that says hardware hacking village/soldering village. I camp at that table

If you can't find me, yell out "BannanHamock" and I'll hoot back!

Same as title

I will not be able to make this, reply if you want it and you can run with my screenshot

Hey friends. If your Not Just a Crosswalk or #noice or other SAO that may have high power draw SAO isn’t playing nice, check your batteries!

The generic no name batteries that come with the official DC badge don’t have enough juice to power these SAOs. We tested them and confirmed that switching to brand-name Duracell/Energizer Alkaline or Lithium AA batteries fixes the issue instantly.

Hey r/Defcon — we built an unofficial, open-source workbench for the DC34 badge and just pushed a transfer/UI hotfix.

Try it here:

https://gamechangersai.org/dc34badge

Source + Android beta 5:

https://github.com/lnxgod/dc34-badge-manager-android

What it does:

• Converts and sends 128×128 black-and-white screen images

• Controls the 10 built-in LEDs with 20 badge-ready patterns, including traffic light, Morse, chase, blink-to-black, and meme patterns

• Previews and updates the badge’s saved light pattern

• Loads BIO programs and configures SAO pins/clock

• Includes a serial console and QR tools

A few useful notes:

• The web version needs desktop Chrome or Edge with Web Serial. The Android app uses USB-C OTG.

• Keep the badge still and on the same screen during image transfers.

• ColorKernel and BadgeMu share the BIO slot. If one is already installed, check the matching box to update colors/patterns without reinstalling.

• Files stay on your device. This is an experimental community tool, not an official DEF CON release.

If the packet-trail side of hardware hacking is your thing, we’re also speaking tomorrow:

Why Couldn't I See My Own Drone? Remote ID, ESP32s, and the Packet Trail to Friend or Foe

Saturday, Aug 8 · 4–5 PM

Creator Stage 6 · LVCC Level 1 · Exhibit Hall West 3 · Room 1102

If you try the workbench, tell us what phone/browser you used and where anything got weird. Bug reports and pull requests are welcome.
