Defcon 14 Badge Hacking Contest Winner - Proof of Concept on YouTube
Title link takes you to the full set of videos. If you don't know what DEFCON is, go here. In short it's a hacker convention. I pulled the following posted by shagghie on this VSE post before it dissapears into the ether:
"Don't ask me how, and definately don't ask me why, but I managed to win a competition I didn't even know was going on at Defcon this year... I hacked the defcon access badge and turned it into an event generator for my analog synth, using $20 of parts from Fry's and some god aweful zero-rosin solder and wayyy to hot of a cheap gun! Originally, I was trying to decipher the last 'mode' on the badge that put out random patterns for the blinking LED eyeballs on the badge...turns out it was a pseudo random pattern after all, but in the process I did discover it repleated every 58 seconds, and that the internal clock ran at exactly 64 bpm.... If you double that you get 128bpm, which is a nice healthy dancable pace... So that's when I thought to install a few piezo tweeters on the badge and tap directly off the IC in order to hear the pattern, and then realized I could install a 1/4" phone plug jack and tap both channels (left and right eyeball) and route it to my analog synth's envelope generator, so that i could great note shapes from both channels. Well, the rest is history, and I was able to get some nice phat techno beats out of it after tuning the synth for awhile. Amazing what redbulls and Fatburgers can inspire!
Little write-up in the Washington Post :/ link
Some pictures of other hacked badges and the badge's creater Joe Grand (aka Kingpin of L0pht Heavy Industries): link
Some VIDEOS of the badge in action, the "Blue Light Concert", the semi-lame demo at the awards ceremony, and a small clip of me setting up for what turned out to be a 7 hour long set at Caezer's Challenge private party. I had to jam for 7 hours straigh, performing live, with no loops, no .mp3's, and help from the occasional curious hacker that would step over to play the keys while I manned the machinedrum...

Defcon takes place at the same place as the CES show (well, where it used to be). The Alexis Park.
ReplyDeleteI've presented at Defcon before. Fun times.
If youtube could handle videos over 100mb, I have some much better quality demos of the badge banging out 128bpm techno beats without the annoying (but cute) piezo tweeters sounding off. I found the MAM RS-3 Resonator to be particularly useful in creating a devastating kick drum out of one of the badge's channels. Next year, we're going to reprogram the IC to be able to step-modulate the voltage and program in an arppegio, so we have left channel being trig, and right channel being (dynamic) note value. Can't wait..now just gotta learn hex.
