Cymatics Sounds Visualized

New Zealand musician Nigel Stanford took various kinds of matter to demonstrate cymatics, the science of visualizing audio frequencies. In one of the examples, he takes a Chladni Plate - sand-covered thin metal surface attached to the top of a speaker - and plays different audio frequencies on a keyboard to move sand into mind-bending patterns. He also uses a vodka-filled petri dish taped to a speaker for playing audio frequencies of 50Hz and 100Hz to form standing waves in the liquid.

Saturn Aurora Sounds

NASA's Cassini spacecraft has been detecting intense radio emissions from Saturn's aurorae, where magnetic field lines thread the polar regions. These signals have been shifted into the range of human hearing and compressed in time. The complex radio spectrum with rising and falling tones, is very similar to Earth's auroral radio emissions. These structures indicate that there are numerous small radio sources moving along magnetic field lines threading the auroral region. Time on this recording has been compressed, so that 73 seconds corresponds to 27 minutes. Since the frequencies of these emissions are well above the audio frequency range, we have shifted them downward by a factor of 44.

Robot Drummer

Researchers at Georgia Institute of Technology have developed a robotic "smart arm" that musicians wear on the shoulder, which can result in epic drum solos. It follows the drummer, and is able to quickly switch between the ride cymbal and the floor tom depending on which other parts the drummer is using, while also changes tempo on the fly. Integrated accelerometers and motors help keep the smart arm on beat. Continue reading for close-up images of the robotic drumming arm.

AudioPill

Why go to a rave or dance club, when you could just swallow an AudioPill? Created by Czech artist Jan Poope, this bizarre device is ingested orally and creates 'a feeling like you are standing in the middle of a concert hall with a powerful audio-system' inside your body. It comes in three preset beats - 95 BPM / 130 BPM / 143 BPM, and once ingested, the pill takes an hour to travel through the upper section of your gastrointestinal tract. Then the party starts with a 'very intensive' pain in your pelvic area, and once that calms down, a 'beating pulse' starts in your abdomen, creating mixed feelings of 'restlessness, amazement, and elation.'

Gittler Guitar

It may look like titanium pipes at first, but the Gittler Guitar is a real musical instrument. It has six strings. Each string has its own pickup. Later versions have a plastic body. The steel frets, consisting of stainless steel bars pressure fitted into the stainless steel neck, give the instrument a sitar-like feel, as it is possible to bend the strings downward past where a wooden fretboard would prohibit the movement in a conventional guitar. Click here for more pictures of the guitar. Continue reading for another hands-on demo.

Fender Cardboard Guitar

Ernest Packaging / Signal Snowboards partnered with Stratocaster to create a fully-playable guitar made from cardboard, and it's so good that Fender gave it a Certificate of Authenticity. "One of the biggest challenges of this neck is with the strings. It has about 250 lbs of torque on the neck," said Dave Lee, co-founder of Signal Snowboard. Mike Martinez of Ernest Packaging spent countless hours designing a solid cardboard core to match the capabilities of a standard Stratocaster. Click here to view more cool custom guitars.

Sure, compact disc players aren't as popular as they were a decade ago, but it's always nice to look back and see how far technology has come. Today, we're showcasing the Sony D-88 - released in 1998 - the world's smallest portable CD player - a 3" disc fits completely inside. To play a standard 5" CD, users had to flip back a blue bar into the lid for the disc to hang out on 2 sides before playing. There's also a switch on the back to move its center drive wheel for switching between 3-5" discs. Click here to view more pictures. Continue reading to see two more hands-on videos.
