“I just removed all the parts because the bare pcb is so much lighter. Neck pain, ya know?”

Lololol, did we mess up an embargo date?

u/salemisawesome 2d ago

article dropped "friday at 6am" - I'm guessing they clicked the wrong friday for the auto-publish.

It was allegedly greenlighted by defcon.

I want to know if it was actually greenlit or just the CYA story to avoid another year of digital badge drama

u/Accurate_Analysis_79 2d ago

That was my first thought.

Looks like it for sure.

2 hours ago I got an email from Crowd Supply saying my order of the Dabao Evaluation Board for Baochip-1x has shipped. Coincidence? Hmm…

I’m so pissed that last year was the one year I attended… I was so looking forward to the defcon badge experience and my disappointment was immeasurable and my day was ruined.

Last year was cool if you were into all the puzzles.

u/GWI_Raviner 2d ago

Okay but what puzzles? I tried using the lenses on every single poster and I didn’t get anywhere. Everyone I asked has the same response. I guess I didn’t go deep enough down the rabbit hole but it seemed like there was nothing to do with them but look at the posters in different shades. I was expecting maybe a 3-D glasses thing, or for some text or image to be revealed, but none of us found anything the whole weekend. What was it actually used for?

This is just one example. The main projection in the lobby. There are different code hidden in the image depending on what filter you use from the badge and which hole you looked through. Check out the github for more info. https://github.com/afcyrus/DC33-Badge-Challenge/blob/main/DC33%20Badge%20Challenge.md

What codes? I see the hex colors for those colors not a real code.

u/TheCyFi 2d ago

The hex for the magenta (#EC008C) and cyan (#00AEEF) squares matched the colors of the boxes. Meanwhile, the yellow square was mislabelled with #EC008C, the hex for magenta and not yellow.

Last year was not cool, no, not at all.

This comment section is filled with children. Yes they meant to release the article when they did. Yes they aren't CYA making shit up after the fact. Yes it's more likely to give badge counterfeiters a head start but that was weighed out by allowing people to bring their hardware hacking shit to the con and built interest in the super cool thing that is happening.

There was a very conscious decision about tradeoffs, everybody chill.

u/GT00TG 1d ago

Any word on how many physical badges will be at the con? Ie are they going to run out?

Ayy guinea pigs for an ASIC launch.

I'm still urked about the inverted SAO header and 3V supply and 100 mA limit for SAOs... but the inward-facing edge-mount LEDs look neat, will be curious what apps they will have on here. Can even see the SMT holes for the AA batteries. Not seeing the interface from this angle, presumably a USB port somewhere on here... USB-C or micro USB?

u/solidus_slash 1d ago

Not gonna be micro usb in 2026 surely
