Bag ‘o badge parts and a blank Defcon16 CD make for a bad day. I got back to the house, opened my badge and put the battery in…nada. Swapped for a ‘fresh’ battery…nada. Looked in the bag and found the pieces parts that should’ve been attached to the board. NP. Check the CD for circuit, components and parts placement…NOT! The CD is blank. DOA badge and CD, what’re the odds of that happening in Vegas?

@dakota c: Oops, looks like you’re right… I used a nokia phone, and zeros and uppercase ‘o’s look exactly the same on it.
I tried the URL with both 3 zeros and 3 uppercase ‘o’s before posting, and both gave me a 404, so I just assumed they were all zeros, d’oh! Didn’t think of trying zeros and Os combined. Well done!

If they could make one with bluetooth and give each person an id to propagate, it could be a very fun game of virus and defense to play, everyone could be involved, whoever had their id on the most badges at the end of the conference would win.

@qrdecodr: A bit off: It's https://defcon.org/OO0/. Two Os and a zero.

I made some edits in Paint to get a more accurate result.

I love the idea about laser tag, I will not be able to attend unfortunately but a huge scale laser tag battle seems great, with the 8 status leds lit up showing lives – make a kill to gain a life, max of 8 last one standing wins a debug kit or summat

AWESOME!!!!!!!!!!!!!!!!!!

Assumption - The badges can communicate freely for any extended period of time.

Assumption - The badges bar codes are unique to the individual badge.

Program the LEDs to flash the contents of your bar code in Morse code, and transmit the virus to other badges.

It'd sure be easier if it used something like bluetooth, though. Maybe that's next year's idea.

According to Kaywa reader, the datamatrix contains the URL https://defcon.org/000
But this is a preview after all...

I can definantly see a badge with a multi touch in it at next years defcon. maybe have a teeny tiny little projector so you can display what you are doing with the multi touch on a wall or something. very cool.

The best part of defcon the last few years has been its badges. So much effort goes into them. Fantastic, next years should have a small display and run linux.

So I got a nice b/w PNG of that datamatrix code. Anybody have a decoder handy ?

just a note, that isn’t a qr code, it’s a 2d datamatrix.
