Wireless Presenters Easily Cracked

July 4, 2010 by 18 Comments

While hacking a wireless presenter doesn’t sound like something worthwhile or interesting, [Niels Teusink] demonstrates that these little devices often are a lot more powerful than we give them credit.

With an Arduino, plenty of research, and some heavy sniffing of a wireless presenter’s SPI and then wireless interface [Niels] is able to emulate an entire keyboard. Sending commands as harmless as “next slide” to the devastating “[Win+R] Format C:”. Hopefully anyone planning such a project at the next Apple or Microsoft keynote just intends some gentle fun.

[Spiritplumber] has been sending us updates on a promising project he’s working on called RobotsEverywhere. We’re not completely sure if that name covers the project itself, or just the name of his group that is selling robots (and giving us schematics and source code). Either way, they have some really cool stuff. The really cool part about many of the bots is that they are using Android phones as their brains and they use the same system on land, air, and water. There’s tons of information sprinkled around the site and the Wiki, take a few minutes and look around.

Hard Drive Destruction Plan

[Wolf] emailed us to show us his Self destructing Hard Drive tutorial. He’s using thermite, like we did, but he’s put a little more effort into the delivery system. In the video, you can see a huge spray molten iron. This is because his “jet”, the block of wood hollowed out to focus the thermite on to the hard drive didn’t hold a seal at the top. Not too bad for try #1. He could probably build this to be more contained, but even then it will most likely turn into “entire self destructing office” if it were to actually be used. A little common sense goes a long way here folks, this is molten metal and is extremely hot and dangerous.
