Oh boy. Just when I thought the forces of good would prevail, those crazy kids at MIT had to come up with a Warcart.
Basically a laptop or two and a bunch of WiFi antennas. The warcart was part of their presentation at DEFCON
describing how they hacked the Boston metro system. It looks like they never actually got to present
because a federal judge placed a restraining order on them. Checkout their presentation
to find out why. It's actually a very good analysis of the problems with security as well as the low-level encoding of the magnetic stripe on the subways cards. Comon' - we all knew it was not encrypted all that well, they just sat down and documented it! Nice work!
TiVo let me down over the weekend and I failed to record the opening ceremonies of the Olympic games. Luckily, we got an email from a SparkFun user who pointed out this fantastic LED wall
Supposedly powered by solar (did anyone else notice the solar panels are not facing the sun?), the 2,292 RGB LEDs demonstrate a pretty impressive control system.
Now for the new stuff at SparkFun...
is a creative combination of a light pipe and a switch actuator. You've always wanted a button that could light up any color - the Icecube does this in style.
Liquidware is kind enough to let us carry their really neat OLED based TouchShield
. Add full color and video to your next Arduino project.
We now carry a range of fun colored bread-boards
. Why you ask? Why not?
9 new, low-cost, simple perf boards have been added. We especially like the 'wired
' PCB that allows you to wire circuits together by cutting traces (subtractive) rather than soldering wires (additive).
Stick a GPS in it. We heard people were experimenting with GPS on the older iPhones and iTouches and thought we'd help out a bit. The GPS iPhone Module
is not pretty, but it'll get NMEA GPS strings into the serial port on any iPhone or iTouch. The pet tracking application is left up to you.
Speaking of... If you need to add audio to your iTouch, here's the microphone
for you - VOIP not included
I really wish they'd put the quarter back in some of these photos. This LCD is about 20 times larger than that microphone. This huge graphical LCD
is 4x5" and weights more than half a pound. If you need to represent a lot of data to a user, from across a room, this large format LCD is for you.
