Build An Acoustic Tractor Beam And Control Objects With Sound!

This is definitely a more advanced project, but with less than $75 in parts, you can build your very own working Acoustic Tractor Beam:

You’ll need to 3D print some parts, and code your own Arduino, and check things with an oscilloscope, but if you’re looking for a fun project that ends with the ultimate desk toy, this is it!

Do All Pixar Movies Exist In The Same Universe?

Pixar Characters

There is a theory that has been passed between Pixar fans, living online and through word of mouth, but never officially confirmed: All of the Pixar movies actually exist within the same universe.

And while the theory hasn’t been officially confirmed just yet, Pixar did release a video on their Toy Story Facebook page that stoked the flames:

Tasty Turns Viral Recipes Into On Demand Cookbooks

Tasty Cookbook

Here’s an interesting gift idea: Tasty, the viral cooking video section of Buzzfeed, is making a cookbook.

Well, actually they’re creating 100,000 different cookbooks.

By using over 1,000 top-rated recipes and grouping them into categorical chapters which you can then mix and match, and then printing the whole thing on demand, they’ve created an almost endlessly customizable cookbook that can be matched to the recipient’s exact cooking preferences.

You start by browsing through categories like Health Nut, Ingredient Obsessed, or Carb Lovers, and then adding sub-categories like One Pot Wonders, Best Desserts Ever, and Hangover. You can then personalize it with up to 300 characters of text (and as many emoji as you can fit) and the result is a customized  gift for the food lover in your life.

Joey Roth and Grovemade Team Up For Wood Speakers

Joey Roth Wood Speakers for Grovemade

Joey Roth has once again created a lustworthy set of speakers that would look amazing at home, on your desk at work, or even on display in a modern art museum.

(I’m a big fan of Joey Roth, and have featured his Ceramic Speakers and Sorapot Teapot on the site before.)

Made of either walnut or maple, the speakers are machined out of solid wood for wood’s superior acoustic properties that create clear and nuanced sound, and then mounted on stainless steel stands. A mathematically ideal horn is integrated directly into the enclosure, boosting the speaker’s low frequency response without the group delay and phase distortion inherent to more common bass reflex enclosures.

Each set of speakers is crafted one at a time in the Grovemade workshop in Portland, Oregon, and requires hours of CNC machining and skilled hand forming to complete.

You won’t find a better looking set of speakers, and with prices that start at just $499, it’s a reachable splurge for the person that wants their speakers to look as good as they sound.
