Single String Servo Electric Guitar

September 28, 2010 by Caleb Kraft 10 Comments

its a catchy tune!

Ah, we love musical hacks that actually play music. [Mike Baxter] is back again with a new servo electric guitar. This one, called the physical string synthesizer, and has only one string. He’s using two Arduinos to control the unit. One to change the midi file to a note within the string’s limits and the second to actually control the servo. It seems like that could be simplified a little bit, but we’re pretty sure his end goal was to build an instrument quickly, not learn to be a circuit ninja. Last time we saw Mike Baxter, he had built a servo electric guitar that used a keypad for control. You can see a video of the single string one after the break.

DRM Causes Vulnerabilities

September 26, 2010 by Caleb Kraft 26 Comments

This image is from Microsoft's DRM page.

We often hear people touting the evilness of DRM, but usually they are talking about the idea of ownership. In this case, DRM is actually causing harm. It turns out that Microsoft’s msnetobj.dll, which is supposed to enforce DRM on your computer, stopping you from doing certain things like saving files you don’t “own” is open to 3 attacks. Vulnerable to buffer overflow, integer overflow, and denial of service, this sucker is riddled with issues.

The vulnerabilities in this file aren’t groundbreaking. Buffer overflow is a common method to get to many systems. The problem here, according to some commenters at BoingBoing, is the fact that this DLL is called every time you open a media file.

Thieves, Armed With A Vacuum Cleaner, Still On The Run

September 24, 2010 by Caleb Kraft 32 Comments

Thieves in Paris have been stealing money with the clever use of a vacuum. Not just bits of change here and there, they’ve stolen over 500,000 euros. They noticed that Monoprix supermarkets use a pneumatic tube system to transport rolls of cash to and from the safe. Realizing this was the weakest point in the security, they simply drilled a big hole in the tube, hooked up a vacuum and sucked the cash out. Forget lock picking or safe cracking, this had to be ridiculously easy.

The thieves are still out there, sucking their way to riches. At this point, they’ve hit 15 locations. Their luck has to run out some time right?

A Fantastic Collection Of Slapped Together Bots

September 23, 2010 by Caleb Kraft 7 Comments

[David Williamson] has put together some pretty amazing little robots from bits of stuff he laying around the house. What initially caught our attention was this drawing robot over at HackedGadgets. We were impressed by the construction, as it looks like almost all of it was scrap. Upon clicking through the link we found a small collection that kept as amused for quite a while. Each one has some aspect that is surprising in its use of mundane materials. Need an omniwheel? Why not use plastic beads. Want a rail from which a robot can hang and drive? why not use drinking straws. Many of them may not have much for a brain, but the construction of the mechanisms is usually pretty interesting alone. You can see clips of some of his creations in the video after the break.

Audio Ads In Newspapers?

September 22, 2010 by Caleb Kraft 33 Comments

Oh no, lets hope this little gimmick doesn’t catch on. Volkswagen has put out an advertisement in an Indian newspaper that plays an audio file when you unfold the paper. This appears to work much like those greeting cards that play a song when you open them. There’s a sensor that detects the newspaper opening, probably just a piece of plastic or paper that slides out from between two contacts. This allows power to the circuit and the audio file is played. Can you imagine how obnoxious this could be? Especially if your newspaper was riddled with these and those E-paper screens. Then again, that speaker looks like massive overkill for this kind of thing and might be a decent piece electronics to keep in the reuse bin. You can see a video of the newspaper after the break.
