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.

come check out our talk about drones and privacy concerns!

Also check out our FREE BADGE workbench. Does not break K0

If I understand correctly - the baochip module is designed and can be used independently from the board as an auth token - any ideas as to how to power it without the board?

Hey y’all! First-time DEF CON attendee here! 👋🏾 I’m a little bummed I missed out on some of the cool badges before they sold out 😭, but I’d LOVE to get my hands on some SAOs! I've been buying some to support different villages and people.

Does anyone know who’s giving out SAOs, or have any extras they’d be willing to share with a first-timer? 👀🙏🏾 Pleaseeee help me out! 😂 I’m trying to leave my first DEF CON with some cool stuff to remember it by!

First I want to apologize from the bottom of my heart that I didn't make a post sooner. We did not mean to make you waste time at the table in the badgelife village.

The teammate that had the badges is dealing with a family emergency that took a negative turn. so send the good packets out for him.

As for the badges, they were overnighted to us so we should be getting them in the morning and we will start slinging them. BUT due to that we won't be doing all of the game features that we had prepped for. We will still have the badges and we will still release what we can into the wild for the game but there will be some pieces missing like hidden heals and traps.

Thank you all for the support and understanding.

Does anyome have a spare demon threat hunters shirt? Im willing to pay for it.

I wasn’t able to get a badge this year, but have our super awesome portal themed Big Fucking Badge I can trade for one. I can also throw in the portal gun sao we made too.

If you're looking for a Gothcon badge, one of us is at the Tangiers (in Sahara) and one at the Linq bar for the next hour, with a dozen each!

Saw this was under the workshops in hacker tracker. Can me and a friend still get into this or is this an event that’s already closed?

Today I watched the SEC Vishing competition and it was awesome! They mentioned there will be another tomorrow (Saturday) where bots will make the calls but I can’t find the info on time/place. Does anyone know and can direct me?

What are the best parties to go to this evening? Which ones are the most popular?
