[Defcon 17] It's on like Donkey Kong.

[Blizz]

Re: It's on like Donkey Kong.

The DC17 badge has a boot loader. You do not connect Codewarrior to the USB port. You need to connect to the USB port like a serial port. If you reset the badge you will see txt come over the USB port. There is another thread that talks a little about this.
The comm port is 19.2 8-n-1 and XON/XOFF

Thank Fly, that worked, I didn't have the Hyperterminal settings correct the first try and also didn't do a reset on the badge.

Re: It's on like Donkey Kong.

I apologize if this is in the wrong thread.

I need help connecting the Defcon schmartboard to the DC17 badge. Can I just wire the USB prop plug directly to the Freescale's TX, RX, GND pads, or do I have to use the schmartboard to connect to the badge? I have tried wiring the USB prop plug TX, RX, GND to the RX, TX, GND pads on the Freescale,but am unable to connect using Codewarrior. Maybe I am doing something wrong in Codewarrior. If anyone can produce a schematic and/or instructions for interfacing the Parallax USB prop plug or schmartboard to the Freescale mc56f8006vlc I will buy you a few beers at DC18.

Thanks

Re: It's on like Donkey Kong.

Like I wouldn't hold one back for you. *chuckle* I just got word from e-teknet that they are in the 2-day turnaround queue, so I should have the PCB's in hand by Monday, and in the assembler that same day. They will literally be done just in time for me to dump some test code on 'em and fly to DC17.

Ah, that's pretty sweet! Looking forward to what you come up with this year ;)

Re: It's on like Donkey Kong.

Very cool! Would you mind saving one for me? I'll trade you for something :)

They have:

• MCU is an Atmel 325P running at 5V/20Mhz
• 2x CR2450 cells (600mAh) 3V to keep 'em running
• Configurable Buck Booster to run at 3V or 5V (10Mhz or 20Mhz) for level matching
• BUILT IN usb mini-b connector + FTDI for instant programming (and power) gratification
• Arduino Compatible pin layout, and mostly Arduino compatible shield connector
• 3x5 LED matrix for character display goodness
• 6 pushbuttons for hacking ( up/down/left/right select/cancel )
• four more LED's for further hacking on the side
• One MORE led on a PWM channel .. um .. just cause

... plenty of hackable goodness ...

Re: It's on like Donkey Kong.

Oh yeah, I'm up for badge hacking. I'm even making badge-hacking-badges ( 5 day turnaround from e-teknet, then assembly. Woo-pah.)

Very cool! Would you mind saving one for me? I'll trade you for something :)

Even if we aren't getting a preview of the specs/schematics of the badges before getting one at registration, an early opportunity to download and install the SDK prior to arrival would be appreciated. All it will give away is the architecture, but with last year's SDK topping out at half a gig, it would help in the fight against Murphy.

Agreed completely. I'm actually writing up the information right now and will post in a new thread shortly.

I can't believe I'm packing for DEFCON again already. Time flies!

Well if you need it, look me up, I have bandwidth to spare, on a 100+ meg pipe.

Re: It's on like Donkey Kong.

I've always wanted to post a message with that subject. Get your soldering irons ready and your coding skills primed. The DC17 Badge Hacking contest, now officially a Black Badge contest, will be happening.

Yes, the badge design is already underway. Hardware is done and I've officially turned into a code monkey until everything works as designed.

More details will come later. :)

Joe

Awesome KingPin !
I'm ready for the specs. Missed out on this last year because it was my first DEFCON and I wasn't familliar with the conference and what to do. I will definately be engaging wtih this activity. Let me know if you need help with anything (before/during DEFCON).
Thanks for spear-heading this !

Re: It's on like Donkey Kong.

No matter what you do, someone will always find a way to do it wrong. This year will be no different. And, the 5 year old should have been supervised! :P

You should make a new class of badge called, "infant-Human," sans electronics and make it out of NERF foam. Even as a joke. Heck, it could be an award for the person that needed the most protection from themselves while playing with the badge.
You could even include text on the badge, "I can has badge borked by me! : Winner!"
Of course, you would need disclaimers on it to make it even better:
"Do no eat."
"Do not insert into Penis"
"This is not a step."
"Objects in mirror are larger than they appear."
...

Re: It's on like Donkey Kong.

Hopefully this year there will be extra pads to solder on components and all of the pins of the chip will be accessible without trying to lift them.

Maybe, maybe not. Remember, I have a challenge of aesthetics versus hackability and I don't want this contest to become some dumbed down, easy, intro to electronics contest by providing everything for you. Having the right skills is part of having a winning badge entry. There will be things people like this year and there will be things people don't. But, I think it's cool.

P.S. 5 year old boys don't realise that the battery is in backwards (hint diode :-) )

A few people have said "Just put in a diode" for reverse polarity protection not realizing that it's not such a simple solution. Last year's badge had a 3V operating voltage (it could run down to 2.8V or so) using the CR123A. The CR123A has a fairly large current capacity and stays at 3V until it's about to breathe its last breath. Then it drops. Simply throwing a diode in series will drop the system voltage *way* below what is useful (even with a 0.4V diode drop, VCC would be at 2.6V).

Plus, like I told the few people that came up to me with burned fingers - it's a hacker conference. If people can't figure out how to put in the battery properly (even with the markings on the battery holder), that's their problem! No matter what you do, someone will always find a way to do it wrong. This year will be no different. And, the 5 year old should have been supervised! :P

Re: It's on like Donkey Kong.

(snip snip)...If it doesn't make it onto the DEFCON CD, I'll burn a few myself and stick it up on my own site, as well...(snip snip)

much appreciated, good sir!

Re: It's on like Donkey Kong.

It's completely up to The Dark Tangent on what information about the badge gets released before the conference. I like the element of surprise, but also understand that it takes time for people to wrap their head around the design before they can start hacking it. WIth that said, this contest is supposed to be a challenge. People have had to deal with very little or no information in previous years and the contest entries have been stellar. I think that says a lot.

As for last year, the development environment was supposed to be on the DEFCON CD, but someone moved it to the network at the last minute (without letting me know) and that caused a lot of trouble. FWIW, the environment install this year is ~280MB. If it doesn't make it onto the DEFCON CD, I'll burn a few myself and stick it up on my own site, as well. I think it would be worthwhile to announce the development environment in advance, so people can at least get their warez set up before the weekend.

More later :)

Re: It's on like Donkey Kong.

According to a post Lost made over on a HHV thread, there will be no information on the badges before con.
