If you haven’t actually used a Keurig coffee machine, then you’ve probably at least seen one. They are supposed to make brewing coffee simple. You just take one of the Keurig “k-cups” and place it into the machine. The machine will punch a hole in the foil top and run the water through the k-cup. Your flavored beverage of choice comes out the other side. It’s a simple idea, run by a more complex machine. A machine that is complicated enough to have a security vulnerability.
Unfortunately newer versions of these machines have a sort of DRM, or lockout chip. In order to prevent unofficial k-cups from being manufactured and sold, the Keurig machines have a way to detect which cups are legitimate and which are counterfeit. It appears as though the machine identifies the lid specifically as being genuine.
It turns out this “lockout” technology is very simple to defeat. All one needs to do is cut the lid off of a legitimate Keurig k-cup and place it on top of your counterfeit cup. The system will read the real lid and allow you to brew to your heart’s content. A more convenient solution involves cutting off just the small portion of the lid that contains the Keurig logo. This then gets taped directly to the Keurig machine itself. This way you can still easily replace the cups without having to fuss with the extra lid every time.
It’s a simple hack, but it’s interesting to see that even coffee machines are being sold with limiting technology these days. This is the kind of stuff we would have joked about five or ten years ago. Yet here we are, with a coffee machine security vulnerability. Check out the video demonstration below.

All-grain home brewing takes time… a lot of time. We’re not going to pretend like a good batch of beer isn’t thanks mostly to the artist that is the brewmaster, but at the same time it’s pretty amazing to see a compact system like the one above that can boil a batch of wort without much help from you.
[Zizzle] built this machine as his entry in the Renesas contest. You can see the development board there just to the left of the brew kettle. It’s network connected with a web interface that allows you to take recipes from Brewtarget and import them directly to the system. All you need to do is make sure that you load up the grain basket and boil addition modules to match your recipe. The bot takes it from there, filling the kettle, preheating that water, lowering the grains and maintaining temperature for the mash, and completing the boil with additions from the servo-controlled PVC pipe pods. Experienced brewers will notice a few steps missing, like the sparge, and a quick way to cool the finished wort. But this does take a huge part of the drudgery out of our hands. If only it had a clean-in-place system… then we’d really be happy! Don’t miss the video after the break and take a moment to check out the build-log posts.

This wort cooler looks beautiful. No, it’s not for removing warts, it’s part of the brewing process for the nectar of the gods. Even if it wasn’t meant to create alcohol, we would be drawn in by those pretty copper curves.
We’re not surprised at all to see this remote-controlled bowling ball. We’ve seen remote-controlled spheres several times and this just seems like the logical conclusion. We wish there were some build details though. [via neatorama]
When [Anthony Toth] an aircraft enthusiast, decided remodel his garage, he shot for the sky. He has recreated the first class cabin of a Pan Am 747 circa the 1970s. It took him nearly 20 years to scavenge the parts and over $50,000 to pull it all together. [via makezine]
This super cheap simple cable tester caught our eye. There’s nothing complicated here, pretty common sense really. Why didn’t we think of it?
Over the years, Asimo has become a household name. At least in geek households. We’ve seen him go from crazy looking walking microwave prototype, to giant scary space man monster, to the lovable little guy we know now. You can see the full evolution of Asimo in this picture series.
Got an old box camera? Want to use it with modern 35mm film? Here’s a guide to getting it to work. It mainly just involves making a simple mounting bracket.
We like LEDs a lot, but this is getting ridiculous. This dress has 24,000 LEDs. They power it with iPod batteries spread throughout the dress. This cuts down on the bulk and helps distribute the weight.
Coffee cup technology hasn’t changed much in the last bazillion years. We’re pretty sure cave people carved them from stone, and now they’re made from ceramic which really isn’t that different. Some researchers are changing all that, and designing a coffee cup that is supposed to regulate its temperature in a new way. This mug is manufactured with internal convection channels and is made from a material known for its temperature regulation called PCM. Interesting, but it will probably cost much more than a simple insulated thermos. [via neatorama]
