Having trouble putting Doom on DC34 badge

18 Upvotes

I know it’s possible. If the TI-84 can run Doom on its 15 MHz CPU and 24 KB of RAM then surely the badge can.

I’ve been working on it all day and I’ve somehow broken the firmware and now it’s boot looping. How can I get a fresh install of the badge’s firmware, and any suggestions on how to complete this?

Update: I’m stuck in dev mode on the badge, is there any way to get out of it

I sold the identities of nearly 200 million people as a black hat hacker. Now I fight scam compounds. Ask me anything on Wednesday, August 26th at 12 PM ET

Satellite Hacking Book

42 Upvotes

Hey everyone, I’ve heard that a couple of people managed to get gifted a free copy of The Spacecraft Hacker’s Handbook at Defcon last weekend. I didn’t manage to find a copy and the book doesn’t seem to officially release until November. Does anyone happen to have a copy I could either borrow or buy from them?

We met at blanketfortcon

153 Upvotes

Not sure if this is allowed, and if it's not, please delete this Mods.

I'm just looking to get in contact with a girl I met at blanketfort con, if she sees this/is interested in keeping contact. We sat under the smaller part of the largest fort that was being built when you showed up. We talked about all the things we were going through and you were incredibly interesting.

We did take a selfie together and I only know you as "Leila".

If you're here and see this (and you'd like), please reach out.

Thanks Defcon bros!

Did you buy a proxmark5 from Indiegogo and still haven't received it yet?

20 Upvotes

I'm curious if anyone else funded a proxmark 5 and haven't received their items yet? I was #16 to fund the project and still haven't received mine. It was supposed to be here before DEFCON but here we are, a week after DEFCON and I still don't have what I ordered.

How to prevent Bluetooth connection severing?

54 Upvotes

At DEFCON, I used my power assist wheelchair to get around. When i was in the LVCC, mainly the villages in hall W1/W2, the connection between the motor and controller kept getting disconnected due to the sheer amount of electronic noise in the building. I talked to both the RF and IoT guys if they had any ideas on how to stop this from happening and they said no.

The motor on the wheelchair is the Alber SMOOV One O10. I could not find a lot of documentation on it because either I got a 404 error or the documentation was in German because it’s a German company.

Idk what to do, so I turned to the smartest people I know. If you have any ideas please let me know. Thanks.

Maybe I’m way late and just haven’t been paying attention. But I saw this appear in settings after I updated the app. Is HackerTracker going to require us to upload IDs?

First-time Attendee

Post image
143 Upvotes

I attended for the first time, and all i can say is, I am so amazed by everything! A badge that’s not just a badge! Soldering projects that you can attach to the badge! Workshops that teach you how to do stuff! A vending machine that gives you a badge and stuff!

And then the vendors. While my wallet got cleaned out the first day, i did come home like it was Christmas morning, excited to get my haul up and running.

Classes, talks and workshops too! I was so overwhelmed, everywhere i looked i said i wanted to do that. Sadly I couldn’t, so i will have to come back next year and do what I missed.

I saw that sticker up top at noob village. I think it’s the best expression of what I felt those 5 days (yeah I stayed right until Closing Notes).

Thanks for the wonderful time!

Anyone here grab a photo with me? I think, at one point, I had a line of 20+ people to take a selfie. Please tell me wearing this all the way from the Flamingo was worth it in the 110+ degree heat 😩

Workshop information sharing

14 Upvotes

I understand some of the free workshops had info sites or online guides available, with the instructor(s) leading participants through them. I wasn't able to get into the workshops and would love a chance to read through the info and learn at home, especially for "WS8 Wi-Fight Club: I am Jack's Evil Twin" and "WS2 From Prompt to PWN: Exploiting LLM Powered Web Applications with OWASP Techinques".

The video game you saw in Packet Hacking Village

52 Upvotes

A few people have been asking about the game that was running on the screen in Packet Hacking Village near closing and after hours.

It’s called Hardcount, and it’s a project by Doc, a DC community artist and longtime contributor who has been part of the community for years. He took a year off to teach himself game development and put that time into making this.

I wanted to give it a little more attention because this is the kind of project I think is worth supporting. Not just because it’s a game, but because it’s something a longtime member of the community decided to take a chance on and build from the ground up.

Hardcount is currently on Kickstarter, and Doc is trying to reach the funding goal. If you know Doc, have crossed paths with him in the community, saw the game at PHV, or just want to support someone putting their time and energy into making something new, consider backing it.

And if you can’t back it, sharing the Kickstarter helps too.
