MBTA Drops Lawsuit Against MIT Subway Hackers

December 23, 2008 by 8 Comments

The Massachusetts Bay Transit Authority (MBTA) has dropped its federal case against three MIT researchers, “the subway hackers”. This happened in October and now the EFF brings news that the students will be working with the MBTA to improve their system. The overall goal is to raise security while keeping expenses minimal.

This whole mess started in August when a gag order was issued against the students’ presentation at Defcon. It’s a shame no one ever saw it because it covers a lot of interesting ground. A PDF of the banned slides is still online. They performed several attacks against both the subway’s fare system and physical security. Our favorites by far were using GNU Radio to sniff the RFID card’s transaction and bruteforcing Mifare Classic with an FPGA.

Finally, A Quiet Xbox 360

coolers

Frustrated by the constant din of his Xbox 360, [Janne Ström] took action. The original case wouldn’t have near enough room for the additional cooling that needed to be installed, so he picked up Lian Li’s XB01 case replacement. He followed the illustrated disassembly guide to get the Xbox stripped down to just its motherboard. He then began fitting his coolers of choice: two massive Noctua NH-U9D0 units originally intended for AMD Opterons. The asymmetric heat sinks are intended for applications like this where dual sockets could make other devices difficult to place. Clearly the hardest part of the installation was applying an appropriate amount of thermal compound and then slowly tightening the hold down screws to guarantee even pressure. The resultant system ended up being quieter than the first camera he attempted to record it with and the attached power supply. You can see a video of it below.

WAP Controlled Home Automation

[Josh] sent in a home automation project he did a little while ago. It has a total of eight switched outlets. The main focus of the project was WAP access for remote control from any cellphone. The control box is based on a design by [Ashley Roll] for controlling eight servos using a PIC microcontroller. A listener app written in Java monitors the control web page and sends signals to the board via serial port. He used opto-isolated 240V solid state relays for each of the outlets. All the pieces are available on the site and he might even do a custom control board design if there is enough interest.

Wiimote Driven Motion Effects

Check out the video above by [Adrien Mondot] for a extensive demonstration of eMotion being used with a Wiimote. eMotion is a physics based visual tool for the Mac. It’s designed to enhance performances by reacting to real world motion. Its grounding in physics makes the resultant motion appear more natural than if they were arbitrarily generated. The video above combines eMotion with the output of Wiimote Whiteboard, a low-cost interactive white board that uses the Wiimote camera plus IR light pens. While the video takes place in a small area, we can see how this could be scaled to a much larger space with IR lights mounted to performers.

Digital Clock Building

clock

[punkky] has been documenting his adventures building digital clocks. They each use six 7-segment LED displays, but he’s been gradually changing how they are built. The first version used a CMOS BCD-to-7-sement latch on each display, which is tied to a PIC16F627a. For the next run, he added multiplexing, so he could drive all the segments using just thirteen pins. He’s posted a final schematic with code and details of how the clock timing actually works.

Cast Concrete RGB Lamp

lamp

[matthew venn] shows us how to create this cool RGB LED lamp. There’s nothing groundbreaking here, but some good information on casting the base out of concrete.  The body of the lap is formed by two thin rods folded in half, stuck in holes in the base, with a lycra sleeve slid over them. The final effect is quite nice and can be controlled by 3 knobs recessed in the front of the base. Information on the actual circuit used is very limited, as there are so many tutorials out there for that, but he does show how he mounted it all, and plans on releasing the source code soon.
