I love making beeps and bloops with the Arduino pitches library, but sometimes archaic 8-bit tunes just don't cut it.

People fundamentally distrust magicians. And they should. The illusions they proffer are just that, illusions meant to astound rather than tangible interactions and results that have weight and meaning in our real world. Our lizard brains know this, and, no matter what the outstanding feat of "magic" presented, we nevertheless hold fast to our survival-based grip on the truth: we just saw simply "can't be real."
It's only normal to snack on a few french fries every once in a while when you're on a diet, but it's still important to hold yourself accountable, even when you cheat just a little bit.

Whether you mean to or not, taking burst photos is super easy on the iPhone. In the Camera app, just compose your photo, tap-and-hold the shutter button, and watch the number of pics go up and up until you take your finger off the screen. However, finding that one special keeper out of all of them in the Photos app isn't as intuitive as taking them in the first place.
A new medical development is going to change the way many of us look at getting the flu vaccine. A painless flu vaccine skin patch is making needles and vials a thing of the past.

When building anything of a social nature, be it a local roller derby or softball team, a club dance night for chiptune, or building new technology markets, the community around those ideas are an important factor in helping these things not only come into existence but to grow into something that enlightens everyone involved. The community around an idea can actually make or break these new ventures — and this applies to augmented and mixed reality as well.
Call them what you will—moss piglets, water bears, or by their real name, tardigrade—but these intriguing tiny creatures can come back from the brink of death.

I record close-cropped videos and take macro still shots with my smartphones on a daily basis, so as you would expect, I spend a lot of time cleaning these devices. Over the course of a couple years, I've fine-tuned my cleaning regimen, and at this point, it's down to a near-science.

While I frown upon any form of uneaten cookie, sometimes we overestimate our late-night cravings for baked goods leaving us with extra cookie dough at 4 a.m. If you're in the privileged dilemma of not having enough excess dough to make another batch of cookies but just enough left over that you can't justify tossing it, don't fret. Here are five effortless and unexpected ways to salvage it.

I was just 16 when I poured my first beer. It was my first restaurant job and a customer ordered a pint while the bartender was busy. I'd seen her do it hundreds of times, and she made it look so easy. Besides, it couldn't be that different from filling a cup from the soda machine, right?
Ralph Waldo Emerson once observed that "the seed of science" was "wonder," and taking a look at this nine-layer liquid tower from Steve Spangler's Sick Science! channel, one can't help but do just that — wonder. How is this possible? Is this magic or what?
Now that everyone has an Android or iPhone in their pocket, there's no excuse for being late to an appointment or job interview. Thanks to that GPS receiver in your smartphone, navigating your way through city streets and highways is a cinch, in or outside of your vehicle. But once you get inside a building, that fancy GPS feature doesn't know what to do. Which direction is the elevator? How do you get to room 819? Where's the nearest fire exit? The bathroom?

1. Remove the old makeup and sealer. If you are working on a vinyl or resin doll, you can remove the makeup with a non-acetone nail polish remover. Afterward, wash the face well with soap and water.

If your doll head is made of resin, in particular, do all your sanding underwater to pr...
