Today we have a special treat, three projects combining the “fastest selling consumer electronics device”, Kinect, and the “fastest selling indie java game that once kept us from sleeping for an entire weekend”, Minecraft!
[Sean Oczkowski] writes in to tell us about his efforts to play Minecraft with Kinect using no more than the OpenKinect Java wrapper on Ubuntu. The code was written in about 4 days with some help from Wikipedia. Using histograms to locate the player in the field of view, the script calculates the center mass of the body and defines interactions for the limb occupying that quadrant of the screen. [Sean] does an excellent job of running through the whole process as well as the decisions made along the way. The whole thing is a bit like running in place, and we can’t imagine the flailing that will occur during the inevitable creeper encounter.
Next we have [Wade McGillis] with his award winning Minecraft Kinect Controller. [Wade] provides source code and executables at his site. This version of control uses skeletal tracking data to sense the user’s gestures. This still involves holding your hands out like a zombie but it is a bit more versatile as one can pass their arms in front of their own body.
Finally [Nathan Viniconis] has been doing some very interesting work using the Kinect to import giant three dimensional models into the game world. [Nathan] then goes the extra mile and animates the figures! Check out the video below for the really impressive results. We here at Hackaday feel that this is the most appropriate use of this technology, and may begin building gigantic statues of ourselves on public servers.
Check out the the tricrafta (minefecta?) of videos after the jump!

The end is near and Lifehacker is looking back on their favorite how-to articles from 2010. We found at least half of these interesting, including the hidden HTPC, lockpicking, and micro-TV-b-gone showcased in the image above. But you can also find tips on using your WRT54G router, stacking malted beverages, and making things glow through chemistry. If your heart goes out to our plague carrying house-mates there’s a no-kill mouse trap. They’ve even included a hack to add a USB port to your car… an article which we covered back in 2009. Enjoy!
You’ve probably been fantasizing about getting amazing gifts this December, like robots with servo-mounted laser pointers and authentic battle damage. It’s time to realize that it’s unlikely that this will happen. Stay calm. You can still get sweet hacky things if you just forward this gift-giving guide to your friends and loved ones.
Join us after the break to see what we want and be sure to let us know what you’ve got your eye on.

Ask any engineer what originally sparked their interest in technology, and almost universally the response will be a Hollywood film or TV robot — Star Wars’ R2-D2, the B9 robot from Lost in Space, or Short Circuit’s Johnny 5, to name a few. Engineers need a creative outlet too, and some pay homage to their inspirations by building elaborate reproductions. At this year’s Maker Faire, droid-builders had their own corner in the center hall, their work ranging from humble craft materials to ’bots surpassing their film counterparts in detail and workmanship.

Since the previously-posted stills can’t quite convey the chaos of last weekend’s Maker Faire, here’s some video from the event to help get you through hump day. It’s like three liters of Jolt Cola in a two liter bottle.
One thing even video can’t adequately capture is our gratitude toward our readers at the show who took time to express their appreciation for the blog. You guys and gals rock our world. Thank you!
Just when you think it couldn’t possibly get any bigger and crazier, they manage to outdo themselves again. The Bay Area Maker Faire wrapped up Sunday evening, but we have so many story leads that we’ll probably be busy until next year’s event. In the meantime, here’s just a tiny, random sampling of the countless delights that greeted visitors this past weekend.

If you’re like us you’ve got quite a few prototyping tools that are bare PCB boards. If you’re using them a lot you might want to protect them with some type of case but the lack of mounting holes can make this difficult. One popular solution to this problem is to design a case for a perfect fit, then cut it with a laser or print it out of plastic. We’ve got examples of both.
[Stewart Allen] set to work designing laser cut cases for the AVR Dragon and the Bus Pirate V2go after seeing our post about on-the-go prototyping. We think this is especially important if you have an AVR Dragon as it’s been known to bite the dust if the bottom is shorted out. If you have access to a laser cutter you can download is DXF files and the models and cut your own.
If you don’t have a laser cutter but can get some time with a 3D printer check out the Bus Pirate V2go printed case and the Arduino printed case.
