For most of us, the only way we can see the strength of a WiFi network is by the familiar signal icon on any given device. Newcastle University School of Architecture doctorate student Luis Hernan, however, has a different method: spirit photography. He's using the new age-y method of capturing someone's aura via electric coronal discharges -- a Kirlian Device -- with a few geeky augmentations (an Arduino Uno board and WiFi Shield, for example) to illustrate how strong a wireless broadcast is with colors. As Wired notes, these components take account of the nearby signal and convert it into color information that's then beamed onto an LED strip; red being the strongest and blue being weaker sections of the network. To create the pictures like what you see above and at the source, Hernan swung the home-made device around after setting up long-exposure shots with a camera. While we can't know for sure, we'd imagine that something with no signal would look a lot like this.

Creators Mike Wakerly and Eric Webb have been at the smart keg game for a while. The two originally sold Kegbot as a do-it-yourself open-source project. They realized there was a market for a little easier option, and developed the plug-and-play version they're currently raising money for on Kickstarter. We recently met up with the team to see the device in action. %Gallery-slideshow164837%

There's something oddly romantic about taking a piece of archaic technology and giving it new life as a work of 21st century art. Take the Royal Empress typewriter you see above. This particular model was built in 1961 and eventually landed in the hands of Amanda Gelb as graduation gift. She and her fellow classmates, Jinyi Fu and Quingyuan Chen, looked at the hunk of aging metal and saw potential instead of an obsolete writing tool. For their installation at the ITP Winter Show, they wired up each of the keys to an Arduino for tracking what a user types, then paired that with a tiny projector that displays the letters on a sheet of paper wrapped around the platen.

The "face" part of the equation comes from the webcam mounted to the top of the typewriter case. It uses brightness to map a silhouette of the person sitting in front of it and fills only the darkened areas with letters, creating an ASCII portrait in real time. The code also automatically loops the letters you type, so even if you press only a single key the picture will appear. Of course, you could also type out a love letter or a quick blog post and the whole thing will be wrapped inside the confines of your outline. When you're done, you can press the re-labeled print key and a laser printer spits out your portrait.

While there are already plenty of apps and sites out there that will automatically create ASCII versions of images, there's something alluring about sitting in front of gorgeous piece of hardware and creating it live. Plus, there are few things in this world as satisfying as pressing down the stiff keys of an old typewriter, hearing the titular onomatopoeia and seeing the letter appear before you. Especially when you know you're creating a work of art, even if you're a terrible writer.%Gallery-slideshow157402%

Conventional wisdom would suggest that making a for-real Katamari Damacy ball would be tricky, but that didn't stop Chris McInnis, Ron LeBlanc and Tom Gwozdz from taking up the challenge. As part of the Nuit Blanche festival in London, Canada (which also included some building-projected gaming), they were able to fashion their very own Katamari ball from a yoga ball, some stickers, wood, an Arduino microcontroller, several optical mice and a dissected DualShock 2 controller. See how it steers after the break.

Bike sharing systems like New York's Citi Bike may be taking off, but it's doubtful that many participants can find every station without checking a map. Thankfully, Adafruit has unveiled a smart helmet project that could help at least a few of those riders get to their destinations while keeping their eyes on the road. The DIY effort feeds locations to an Arduino-based Flora board and its positioning add-ons, which in turn use a string of NeoPixel LEDs on the helmet as turn indicators. Commuters just have to watch for blinking lights to know where to go next. While the system isn't easy to set up when cyclists have to manually enter coordinates, it is flexible: the open-source code lets it adapt to most any bike sharing system or headpiece. As long as you can get over looking like a Christmas tree on wheels while you navigate, you can build a smart helmet of your own using the instructions at the source link.

We've already seen cockroaches turned into unwitting puppets for human overlords, but never have we seen dominance quite so casual as with Brittany Ransom's recent Twitter Roach art project. While part of the exhibition, one of the insects wore a modified RoboRoach backpack with an Arduino add-on that took commands from Twitter: mentions including specific hashtags steered the roach left or right by stimulating its nerves. Yes, that meant the poor roach rarely had the dignity of seeing its master face to face, although there's some consolation in knowing that it wore the backpack for limited periods and had a required 30-second pause between instructions.

As to why Twitter Roach came to be? Ransom tells CNET she imagined the currently dormant project as a reflection of the "overstimulation" us humans encounter in a digital world. We can certainly sympathize given our livelihoods, although its existence makes us nervous about 2013. If we're fighting off remote-controlled insect armies a year from now, we'll have to admit we had fair warning.

Sometimes the plays on words are unavoidable -- in fact, they form the very heart of Scott Garner's recent musical creation. His BeetBox turns six of its namesake root vegetables into drum pads through SparkFun capacitive touch sensors, all of which are controlled by (what else?) a Raspberry Pi. Cleverness goes beyond the core technology and food jokes, as well. All of the circuitry and audio equipment is hidden within the wood box, making it look more like a horticultural project than machinery. We don't mind the lack of production plans when there's source code available; we're mostly curious as to what in our garden would make for a good rhythm section.

End-of-year engineering school projects often pique our interest for their creativity. It's not every day that they can carry a bassline, however. James McVay's robot project for his honors year at the Victoria University of Wellington, the supremely well-named MechBass, wouldn't have much trouble keeping up with a favorite band. It centers on a custom, Arduino-compatible board that controls the plucking, fretting and damping of four strings to faithfully recreate bass guitar sounds from MIDI input. The design even accounts for the unwanted noises of actuators and motors, while virtually everything was either 3D-printed or laser-cut just for the task at hand. Sounds good? There's more in the pipeline: an upcoming Swivel robot will experiment with different playing techniques, and McVay ultimately sees his work teaching us about robotic music's interaction with human performers. For now, we'll be happy with the video after the break and hope that MechBass takes requests.
