[Melanie] had some time this weekend so she whipped up a dual voltage power supply from parts on hand. This design plugs right into a breadboard and, unlike the last breadboard power supply we saw, provides two voltages at one time. 5v is delivered to one power bus while 3.3v goes to the other. Her design uses two linear low voltage drop regulators from the LF00 family (PDF datasheet) to accomplish this. Nice work!
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.)

The iPhone doesn’t have the market cornered on the use of accelerometers. The tiltphone project incorporates a three axis accelerometer into a set of headphones transforming them into a remote control for an iPod. A PIC16F690 reads in data from the analog sensor, translates specific movements into commands, and like the Arduino iPod Remote from last week, relays them to an iPod via the Apple Accessory Protocol. A quick nod left or right skips tracks, holding a sideways nod controls the volume, and setting the headphones down pauses.
This project is a bit older but we’re glad [anon] tipped us off as we hadn’t seen it before. There doesn’t seem to be any code or schematics available but because the Apple Accessory Protocol is known, it’s only a matter of working out how to interpret the sensor data. There is video after the break and if you pull off this hack yourself be sure to send in details for a followup.

Hard drive speakers aren’t anything new, but they have yet to be done very professionally. Most hard drive speaker hacks are awesome, but aren’t meant to be a showpiece. [Oliver] took the opportunity to put together a set of 20GB drives and a custom-built acrylic case with a horizontal VU meter up front. The project is well-photographed and documented and can be recreated without the use of laser cutters or other expensive tools. The only thing it’s missing is an iPod dock!

[Dan] set up this simple cell phone hack to disable his microphone when he’s not using his cell phone. He had read that the government can listen to you using your cell phone, even when it is off. This concerned him enough to hack into his phone. He removed the expansion port and wired the microphone to a magnetic reed switch. A strong magnet located in the screen side of his flip phone opens the circuit when he closes the phone. He notes that you could always just pop the battery out of your phone, but then you are left completely disconnected. This mod allows you to still receive phone calls.
Ars technica is reporting on the ruling from the FTC about the software shenanigans of Kmart and Sears. The marketing geniuses behind the parent company of Sears and Kmart decided they needed more information about the users of their website. Their solution? Offering $10 to users who install their custom software which phones home with data on just about everything they do on their computer. Not content with just browsing habits of webites, the software apparently recorded everything the user did online, including secure sessions. Under the settlement (PDF) with the FTC, Sears says they will stop collecting data and promises to destroy any and all information they’ve collected so far. Selling what websites you’ve been to, how much money you have, which prescriptions you take and what products you’re interested in for the low low price of $10 seems like a bargain.
Sometimes we need someone like [FireMyLaser] to show us that you really don’t need things like custom PCB’s, expensive tools, or laser cutters to pull of a hack. His laser spiro subsists mostly of toothpicks, hotglue, and determination. It is a two motor spiro with a base motor and a motor mounted in a spinning cage. The cage gets power through brushes much like other projects we’ve covered. See a video of it in action after the break.
