Child of the ’80s? Then you’ll most likely remember those notorious PSAs about your brain and eggs, and the dangers of turning yourself into an omelette. Yeah, well turn off your inner Nancy Reagan for a second because we’ve got an Arduino hack that should have you just saying yes. New Zealand artist Rich Decibels created a homebrew brain entrainment device that uses low frequency sound and light to induce different mental states. The mod pieces together an Arduino Uno with two separate interface boards — one for pitch and separation controls, the other for LED and volume — to deliver a combo of binaural beats (two slightly out of sync tones) and flashing headset-mounted lights that’ll slow down those cerebral hertz cycles. If you happen to live in the land made famous by Frodo’s Shire, you can check out the brain-slowing goods at Thistle Hall’s Project Briefcase exhibition. Not a Kiwi? Then be sure to hit the source for an audio taste of this hacked head experience.

From now on, you won’t even hear the black helicopters coming. Just a breath of wind rustling your blinds, and then — bag on the head! At least, that’ll be the case if the NSA gets hold of some of these Blue Edge rotor blades from Eurocopter. They’re not only shaped like a sword you might find in Final Fantasy XIII, but they have little mechanized flaps that are automatically adjusted in order to reduce the wup-wup-wup noise that results from the blade cutting through turbulent air.

See? Hear, rather?

If you’re interested in a more technical perspective, Autopia’s got it. There’s still a long way to go before these things are actually quiet enough to sneak up on you, but I’ll tell you what, I guarantee nature photographers are going to enjoy these things. Losing a few decibels means you can hover a couple hundred feet closer to your subject critter.

Please indulge me as I begin this post with a quote from the Ultimate Ears 18 press release:

“The Ultimate Ears 18 Pro Custom Monitors are expected to be available beginning in February for a suggested retail price of $1350 (U.S.). (The price of the Ultimate Ears 18 Pro Custom Monitors does not include the initial cost to have a qualified audiologist create your ear impressions.) The optional ambient noise feature can be added to your custom monitors for an additional $50 (U.S.).”

I’m not entirely sure how much it costs “to have a qualified audiologist create your ear impressions,” but I’m guessing that it’s not a service offered at your local Sam’s Club.

If you’re an aspiring musician, though, think of these things as a big fat write-off on next year’s tax return. And if you’re a professional musician, you probably already have these or something comparable. For the rest of us, $1350 plus a trip to the neighborhood audiologist just isn’t in the cards, financially.

As for the nuts and bolts, each earbud contains six speakers. How do they do that?! They also reduce ambient noise by 26 decibels. Here’s more:

“In addition to the six-speaker design, Ultimate Ears’ newest monitors combine four-way crossovers with acoustic and electrical tuning, patent-pending triple-sound channels and a new low-distortion cable to create the Ultimate Ears sound signature. Each sound channel includes an acoustically tuned in-line filter that keeps the frequencies separate and balanced until they blend naturally in your ear – not inside the monitors.”

Sounds nice. Pun intended.
