Guy Builds Own Air Raid Siren, Neighbors Probably Not Too Happy

Builder Matthias Wandel is known for his awesome moving marble contraptions, which certainly can make some noise. But now, he’s gone and taken his DIY skills and applied them to a much louder noisemaker – his own air raid siren.

He built it by attaching a pair of spinning wood disks with specially-curved air channels, and then attaching them to a powerful blower motor. These are lined up with a set of matching holes, which cause air currents to intermittently blow out and create the familiar, whiny sound of a siren.

While Matthias’ siren doesn’t even have a horn on the front of it, it’s still quite loud. In fact, it’s so loud that he has to take it out to the country to test it out in this video clip:

I can only imagine how much louder this thing would get if he attached a giant horn to this thing. You can check out the full build process over on Matthias’ website, Woodgears. And promise me you won’t build one of your own if you live anywhere near me.


Own Your Own deadmau5 mau5head. Holy 5hit.

If you’re a fan of deadmau5, and have a massive budget for your Halloween costume, here’s something that’ll blow all your friends away. It’s a replica of the performer’s famous light-up stage head, and it can be yours for the low, low price of $2750 (USD).

It was made by Etsy artist Jeffrey Nappi, and it has an orb-shaped helmet, covered in 168 RGB LEDs, along with electroluminescent mouse ears. It’s operated by a San Devices E680 pixel controller and Madrix computer lighting control software which can be programmed to display any imagery you’d like. While it’s not quite as awesome as this guy’s version that uses over 760 LEDs, you can’t buy that one.

In case you’re wondering how you see out of this thing, the helmet is actually made from a see-through acrylic globe, so I can only imagine the trippy, rave-like experience you’ll get wearing this thing. Here’s a video montage showing Jeffrey’s build process, as well as the helmet in action:

And some more footage of the head reacting to music (and playing a little Tetris):

If you can’t spare the nearly $3000 to buy a pre-built one from Jeffrey, you can attempt to build your own from the parts list and source code provided up on GitHub. But for those of you with the budget, and the lack of technical skill, you can order one over on Etsy now.


The Happiness Machine Prints Out Little Doses of Joy from the Internet

There are a lot of things to be sad about these days. Inflation. War. Poverty. A beaten-down spirit is no good in these trying times. Brendan Dawes knows this, which is probably why he came up with this awesome project called ‘The Happiness Machine.”

Happiness MachineIt’s basically an Internet-connected printer that scans the world wide web for snippets of positivity from We Feel Fine. It’s been programmed to only print stuff that contain the word ‘happy’, hence, its name.

However, it can also be programmed to print other stuff like train schedules or the daily news. Pretty nifty, right?

Brendan showed off an updated version of The Happiness Machine at the London Design Festival 2012. Instead of just printing happy stuff, people could also choose to print sad feelings by selecting their preferences on the printer’s capacitive touch buttons.

Car & Bike Horn Mod is Bleepin’ Loud

Peter Olt nearly got into an accident when a car suddenly cut into his lane, unable to hear – or perhaps ignoring – his honking and cussing. The incident prompted him to make some noise, so to speak. Olt invented a loud vehicle horn called the Screaming Banshee. Now he’s raising money to produce a smaller variant, the Whining Siryn the Plug & Play Screamer.

When installed, the Plug & Play Screamer gives you two horns. Tap your car or motorcycle’s horn button and you’ll get the standard sound. But if you hold it down you’ll get a 120dB sonic attack and your headlights flash for a split second.  The Screamer is quieter than the Screaming Banshee, which can go as loud as 139db, but it’s also easier to install. It has four wires – two connect to the stock horn, one to the battery and one to the high beam lights. Olt will also make easy to follow video instructions for newbies.

Pledge at least $79 (USD) on Olt’s Indiegogo fundraiser to reserve a Plug & Play Screamer. The only thing I don’t like about this invention is that it could be abused in the wrong hands. We have enough obnoxious drivers as it is.

Hacked Pacemaker Transmitters Could Turn Pacemakers to Literal Heartstoppers

Pacemakers save millions of lives, but a security researcher has shown that they can be used to kill on a massive scale as well. Speaking at the Breakpoint security conference, Barnaby Jack of IO Active reverse engineered a pacemaker transmitter – a device like this one used to monitor installed pacemakers – eventually enabling him to wirelessly deliver 830v shocks to a pacemaker using his laptop. Yikes.

Even worse, Jack warned that a hacked transmitter could control all pacemakers within 30ft. Aside from jolting people, the compromised device could also be used to read and write patient data or load infected firmware into a pacemaker. These infected firmware could even be made to jump and infect other pacemakers, extending a malicious attackers’ range and possibly resulting to mass murder. Jack says he demonstrated this flaw in order to warn pacemaker manufacturers to step up the security of their device. Let’s hope they do.

Finger-Mounted Sensor & Camera: You Got the Touch

The explosion of touchscreen devices have not made the mouse obsolete. But what if you could use your finger as a mouse on any surface? That’s the point of Magic Finger, a concept device made by a team from Autodesk Research and the University of Toronto that can sense touch, motion and texture.

magic finger autodesk research

The Magic Finger is basically a micro RGB camera, an LED and an optical mouse sensor cobbled together. Talk about ripping off the mouse. Contrary to its name, the magic here seems to be in the software. Aside from letting you point and click on any surface, the camera can also recognize different textures, which the researchers use in a variety of ways, such as reading data, launching applications and controlling other devices. Watch the dorky demo in the video below:

I’m not too sold on the Magic Finger for a couple of reasons. First of all the Magic Finger is intrusive; the finger or hand wearing the device will be of limited use because you don’t want to damage the Magic Finger. Second, I don’t think the data matrix or the Morse code transfer is practical. That said, the shortcuts and its use as a mouse could be very practical. Perhaps those two functions could be integrated in a less intrusive device like Google Glass or Digits.

Gold Macbook Air: More Than Worth Its Weight in Gold

The first version of the MacBook Air was prohibitively expensive, particularly because it was quite underpowered. The 2012 edition is much more practical, and with the release of the 11″ version, is more affordable as well. Computer Choppers is here to tip the scale back to the other end with their 24 carat gold plated MacBook Air.

This has to be the most functional piece of bling in the world.

Portal Gun Turned into Gravity Gun: Levitates Companion Cube

One of my favorite guns in the history of video games has to be the Gravity Gun from Half-Life 2. Perhaps my second favorite is the Aperture Science Handheld Portal Device, which admittedly is more of a tool than a gun. Now, the smart guys over at Hack-a-Day have combined them both – sorta, kinda.

levitating companion cube gravity gun

How, you might ask? Caleb Kraft took his off-the-shelf model of the Portal gun, and added a levitation device to the front of it – currently capable of lifting a small model of the weighted companion cube. He achieved this by hacking his StellaNova magnetic levitating globe and tearing the magnetic coil from the desktop plaything (throwing the Earth off its axis and ripping a hole in it in the process.) He then attached the coil to one of the arms of the Portal gun, and attached the magnet from inside of the globe to a foam model of the companion cube.

Check it out in action in the video below:

Cool, no? Unfortunately, the magnetic levitation field doesn’t hold up well to movement, and can’t really lift anything very heavy. Too bad. I was really looking forward to picking up some circular saw blades and flinging them at zombies this Halloween.

Entire World of Warcraft Map Recreated in Minecraft: WoW Indeed

Minecraft Forum member Rumsey made a full-scale replica of the World of Warcraft map made of Minecraft blocks. He wrote a custom application that automatically voxelized every bit of WoW, “down to the last tree stump”, to create a Minecraft map made of 68 billion blocks. I’m still struggling to comprehend how this is possible.

Rumsey said his program took about 24 hours to complete the conversion. Even though the process was automated, Rumsey still had to do a lot of work to prepare for it, saying, “Prior to the conversion process, I needed to match textures from World of Warcraft to the appropriate material in Minecraft. For example, an object with a wooden texture might be converted into wooden planks, while an object with a mossy texture might be converted into mossy cobblestone. I created a special program to help do this assignment, but selecting materials for all 10,000+ textures in the game still required many hours of work.” I can imagine. Actually no, I can’t.

As you might have guessed, the map files are also huge. They’re in a 2.17 GB zip file that balloons to nearly 24 GB when unpacked. YouTuber svmgaming has a guide for Windows users on how to install them if you’ve got the available space. You can see footage of the map about 5:30 in:

Head to the Minecraft Forum for more information and pictures, as well as the link to the torrent file needed to download the map. I’m not sure which is more impressive – this or LEGO Middle-Earth.

Ben Heck’s Bionic Sunglasses Automatically Make You Look Cool When It’s Bright

If you watch Ben Heck’s online show you’ll notice that the master modder has branched out beyond the gaming mods that made him famous. For his latest episode, Heck shows us how to make a very practical gadget: sunglasses that automatically raise or lower a pair of polarized clip-on shades depending on the ambient light.

Heck used an ATtiny board, a photo cell and a servo to modify his own sunglasses. Lesser mortals not versed in tinkering and programming will most likely zone out within two minutes of the clip; you can skip to about 11:55 in the video below if you’d just like to see the finished product.

I guess now we know what Dwayne Wayne could look like… in a different world. YEEEAAHHHHH
