Quit fucking around on Slashdot and hire a hardware designer.
It doesn't even have to be an EE. Right now hobbyists are going from idea to product without any formal training.

Hack a Day asked cold boot team member Jacob Appelbaum what he thought of the approach.
Here's Jake's unedited response:
Here's Jake's unedited response:
Yeah, it's not a solution. It simply seeks to make it more obscure but an attacker would certainly still be able to pull off the attack.
From what is on that blog, there's still a full keyschedule in memory at this time. This is how we reconstruct the key, the redundant information in memory; it's not just the 128/256 bit key itself. For older methods, they needed the actual specific key bits but we don't need them because we recreate them.
Basically, the CPU is acting as a ghetto crypto co-processer. Emphasis on ghetto. It's a nice suggestion but the devil is in the details and sadly the details in this case aren't really up to snuff. It's a bogus solution.
Submission + - Web server on a business card (hackaday.com)
mollyhackit writes: "We've seen tiny web servers in the past, but rarely ones that are home built. Here's a guide to building your own tiny web server with a footprint no larger than a business card. The design uses two major chips. One handles the SPI to MAC/PHY translation for the ethernet jack. The other chip is a PIC24F, which hosts a simple web server and reads files stored on a microSD card. All components run at a low 3.3volts. Part of the compactness of the design comes from the PIC24F having programmable pins; only four jumper wires were needed. The single sided SMD design is easy to manufacture at home. Part 1 covered many of the 24F's features and both posts have full code available."
Submission + - Multicolored keyless entry system (hackaday.com)
mollyhackit writes: "Here's a how-to guide for building a keyless entry that uses color identification instead of numbers. All eight buttons are initially blue; as you press the individual buttons they change color. Cycle the colors to your particular pattern, and you're in. This lock obviously wasn't designed for high security use since anyone in the same room would be able to see you and your amazing technicolor dream lock's pattern; it's just a fun project and will keep the youngins out of your workshop (timer prevents brute forcing). The RGB buttons are monome clones from hobby shop Sparkfun."
Submission + - Open Source Graphics Card For Sale Now (hackaday.com)
mollyhackit writes: "The Open Graphics Project, which we've been following since it first started looking for experts four years ago, has just announced that the OGD1 is available for preorder now. The design features 2 DVI, 256MB RAM, PCI-X, and a Xilinx Spartan-3 FPGA along with a nonvolatile FPGA for programming on boot. FPGAs are reprogrammable hardware which means the graphics card can be optimized for specific tasks and execute them faster than a general purpose CPU. The card could be programmed for certain codecs to speed up encoding or decoding. An open hardware design means potential for better driver support. Of course you could always use the FPGA for something else... say crypto cracking."
Submission + - GPL vs. Skype back in court (hackaday.com)
mollyhackit writes: "Hackaday reports that the GPL vs Skype case is going back to court tomorrow. This as an appeal to the court's decision Slashdot reported last July. The original case was brought against Skype for the Linux based SMC Skype WiFi phone. The court upheld the GPLv2 and decided that Skype had not gone far enough in meeting section 3 which details how to provide the original source. This time around Skype is apparently trying to argue that the GPL violates anti-trust regulations."
