The people at Near Future Laboratory are trying to spoof the behavior of a Playstation 2 controller using just a microcontroller. They wrote some initial code using the controller info found here, but decided the best way to figure out what was going on, was to probe the interface. They’re using a Logicport, which features 34 channels plus … Read the rest

Ice on Mars
June 19, 2008 By 22 Comments
It’s official: the Phoenix Lander has discovered ice on Mars. A few days ago, the lander exposed some bright white chunks of material while retrieving a soil sample. These spots have since disappeared over the following days, suggesting they’ve melted. An additional trench found a hard layer at the same depth as the original ice.
The spacecraft team has … Read the rest
EM Brace for sensing magnetic fields
June 19, 2008 By 7 Comments
We’ve discussed the notion of using machines to add or improve sensory input to the body before, and we’ve found another project with the same idea. [Nick Hasty] has developed an object he calls the EM Brace, which allows the user to sense electromagnetic fields with a wave of the hand.
The device works by connecting two antennas to an … Read the rest
Eavesdropping encrypted compressed voice
June 19, 2008 By 1 Comment
A team from Johns Hopkins University has discovered a way to eavesdrop on encrypted voice streams. Voice data like the kind used by Skype for its VoIP service sends encrypted packets of varying sizes for different sounds. The team learned that by simply measureing the size of the packets, they could determine what was being said with a high … Read the rest
3-digit frequency meter
June 19, 2008 By 5 Comments
Flow sensors are useful tools for collecting data on the rate of liquid usage, but they need a device to display the data they collect. This three digit frequency meter was designed by [Turbokeu] to do just that, converting a Swissflow SF800 flow sensor’s square wave signal (similar to fan RPM signals) into an numerical expression of liters per minute … Read the rest
SparkFun’s Logic Level Converter
June 19, 2008 By 8 Comments
SparkFun has always been good about designing and stocking useful breakout boards. This recently added Logic Level Converter is no exception. It’s uses two BSS138 MOSFETs to shift 5V logic levels to 3.3V. The board handles two separate serial pairs. Just hook up the RX and TX on either side. Provide power at both voltages and the board will happily … Read the rest
OpenSUSE 11.0 reviewed
June 19, 2008 By 7 Comments
Download squad has posted a thorough review of OpenSUSE 11.0. Previous versions of the Linux distro were plagued by thorny and confusing installations, but OpenSUSE 11.0 installs much more easily and cleanly. After a few standard configuration screens, the user has several options for admin accounts, disk partitions, dual-boot setups, and more. The installation of the OS files takes … Read the rest
