Building An IR Receiver For The Popcorn Hour C-200

[Linuxworks] has posted a writeup on how to build an IR module for the popcorn hour c-200. We weren’t familiar with the popcorn hour c-200, so we had to look it up. It seems to be a media center pc sort of thing. We’re not reviewing the unit itself, since we’ve never used one, so we’ll just get back to the mod. The device uses an RF remote, which some people didn’t like as much. Luckily it has an expansion port which can be utilized to get IR signals into the machine. [Linuxworks] has used a cheap IR sensor and a standard headphone plug. He notes that equipment passing power through these plugs should be turned off before plugging them in or removing them as they short momentarily during insertion.

Microsoft Unveils Open Source Multi Core OS

group (Custom)

A new operating system, code named Barrelfish is being developed by Microsoft research labs and ETH Zurich in Switzerland. This operating system is being built with multi core operations foremost in priority. It is supposed to be extremely scalable and able to function on a very wide range of hardware. You can download the current snapshot of it on their site and dig into the source code, released under a 3-clause BSD style license. If you would like to learn the primary differences between this OS and Windows or Linux, you can read this PDF.

Internal Wireless Headphones

Wireless headphones can be a wonderful way to help clear up the clutter inherent in most desktop PC systems. However, after plugging a wall wart in, and the headphone jack into the computer, the number of wires used has actually doubled. After [Parker] found an old set of JVC 900 Mhz wireless headphones (and a generic 900MHz transmitter), he cracked open the case to see what he could do with them. Realizing that the transmitter used a 12V DC source, he powered it with an unused floppy connector (which provides +12V, +5V, and two ground lines). He also wired the audio-in line directly onto his sound card headers rather than feeding out a headphone jack to the back. He then wrapped the whole thing in plastic to prevent unwanted shorting and placed it back in his PC, leaving him with a very functional wireless system. Detailed photos after the break.

SLI Anytime Anywhere

SLI, for those who don’t know, is the process of taking two Nvidia graphics cards and allowing them to work in parallel to render to a single monitor. In theory this doubles the power, getting more FPS for video games. Great right? Except due to encryption, only a limited amount of motherboards can actually support SLI.

That is, until now. Russian hackers at xDevs discovered that the newer encryption is based around string identifiers. This can be modified within the operating system itself, so in theory any motherboard could work. Be wary, this could brick your system; but if successful, you’ll have more power without shelling out for an officially SLI supported motherboard.

Android App “tests” Windows Vulnerability

An Android App for “testing” the Windows SMB2 vulnerability we covered last week has been released. For testing? Yeah right! The availability of this kind of software makes it ridiculously easy for anybody to go out and cause some havoc. Go right now and double check that your machines that run Windows Vista or Windows Server 2008 are protected (see the “workarounds” section.)

In-depth MAME Cocktail Cabinet Build

Recently, a friend of ours got married who is a Ms. Pac-Man fanatic. His best man set out to fulfill the groom’s dream of owning a Ms. Pac-Man cocktail cabinet. The problem is that the unit he was after was selling for $2500. It’s great to buy the real thing (and with guest contributions he did,) but if it’s not available consider building your own.

[Alex] has put together a comprehensive guide for building a MAME cocktail cabinet. Unlike the mini-cabinet we saw last week, this is intended to be used sitting down and features controls on more than one side. His guide details the use of an original arcade CRT or an LCD flat panel, high-end controls via an I-Pac 4 controller, and a PC running MAME and MaLa software for Windows. The result is a professional looking build with controls on three sides of the table.

Windows 7 And Vista Crash Via SMB Exploit

September 9, 2009 by Mike Szczys 40 Comments

[Laurent Gaffié] has discovered an exploit that affects Windows Vista, Windows 7, and possibly Windows Server 2008 (unconfirmed). This method attacks via the NEGOTIATE PROTOCOL REQUEST which is the first SMB query sent. The vulnerability is present only on Windows versions that include Server Message Block 2.0 and have the protocol enabled. A successful attack requires no local access to the machine and results in a Blue Screen of Death.

[Laurent] has a proof of concept available with his writeup in the form of a python script (please, white hat use only). There is no patch for this vulnerability but disabling the SMB protocol will protect your system until one is available.

Update: According to the Microsoft advisory this vulnerability could lead to code execution, making it a bit worse than we thought. On the bright side, they claim that the final version of Windows 7 is not open to this attack, only Windows Vista and Windows Server 2008.
