The first annual Guthman Musical Instrument Competition proved to be a very interesting place to be as hacked musical instruments competed for $10,000 in prizes. 60 people applied and 25 were chosen to show off their hacked together, strange, and whimsical instruments. There were all kinds of creations, from keyboard controlled motor cycle engines to tongue controlled synthesizers. We can’t imagine trying to pick some kind of a winner from the bunch this diverse.
“Reformat it”. That’s pretty much our default answer when someone calls us complaining of malware and viruses. Though many can be removed, it can sometimes be quicker and less frustrating just to reformat it. Some of us even have specific ways that we organize all of our files just to make the quarterly reformat go smoother. Unfortunately, reformatting may no longer be the absolute cure. Researchers have developed a piece of malware that infects the BIOS. It is un affected by reformating or flashing. This means that it is also OS independent. They tested it on Windows and OpenBSD as well as a machine running VMware Player. This is a grim sign for the future.
Reader [Will R] sent in a thermostat mod for his brew fridge. His friends had found a perfectly fine bar refrigerator and wanted to repurpose it for brewing beer. A previous batch of microbrew had been mangled by the Australian heat so they wanted something that could maintain the perfect temperature. The fridge’s built-in thermostat wouldn’t rise above 5 degrees so they had to build their own. [Will] used a 10K NTC thermistor to measure the temperature. It’s connected to an ATtiny25 microcontroller that does the comparison and determines whether to turn on the compressor. He referenced SparkFun’s relay tutorial for the switching side. Although he didn’t etch a board for this project, the design file is included along with all the code on the project site.
From the same person who brought you the NES toaster comes the Super Nintoaster. It looks like the most difficult part of the construction was extending the cartridge connector. The slider button works as the power button. The toast control now changes the brightness of the glowing red LEDs. Video introduction embedded below.
The creator of the pac man modded roomba is at it again. This time, [Ron Tajima] is going in a completely different direction. He has made a baby cradle attachment for his roomba. We don’t know what safety concerns there might be, but the baby seems OK with, so far. We’ve seen robot baby cribs before, but they cost much much more and don’t clean your house.
[derektroywest] has posted a detailed step by step breakdown of making a Daft Punk costume. They’ve done a great job, the overall look is very convincing. They include links to where to get each part as well as information on how they pulled it off. The helmets were inspired by the timelapse Daft Punk helmet build. As you can see in the video, they don’t have the entire visor made into a display, but the effect is quite nice, especially because it is multi color.
[Alex] put together this lovely minimal LED project. The square pixel matrix is soldered directly to the microcontroller in the same style as EMSL’s Micro-Readerboard. During the prototyping phase he used resistors to limit the current from the programming board. The final product doesn’t use resistors and manages the current draw by only turning on a single pixel line at a time. The illustrated assembly guide is very thorough and should help your create an equally compact device. Check out a video of it in motion below.
Researchers from Inverse Path showed a couple interesting techniques for sniffing keystrokes at CanSecWest. For their first experiments they used a laser pointed at the shiny back of a laptop. The keystrokes would cause the laptop to vibrate which they could detect just like they would with any laser listening device. They’ve done it successfully from anywhere between 50 to 100 feet away. They used techniques similar to those in speech recognition to determine what sentences were being typed.
In a different attack, they sniffed characters from a PS/2 keyboard by monitoring the ground line in an outlet 50 feet away. They haven’t yet been able to collect more than just single strokes, but expect to get full words and sentences soon. This leakage via power line is discussed in the 1972 Tempest document we posted about earlier. The team said it wasn’t possible with USB or laptop keyboards.
