Under Water Record Player Is Very Mesmerizing

February 16, 2014 by James Hobson 36 Comments

Once in a while we get a really awesome tip about a technical art installation — there sometimes isn’t much info behind it, but the idea and concept behind it alone sparks our curiosity. That is most definitely the case for this submerged record player.

Artist [Evan Holm] has created this awesome installation which features a black pool of water — with a built-in record player. He’s somehow waterproofed the player itself, and integrated the controls and needle into a tree, which is part of the installation.

He has a very long and artsy description about the meaning of it, how it represents loss and mystery, and the collective subconscious of the human race… We just see it as a really cool hack. There’s also a full documentary about how he sets up the installation at various shows.

We’ve included both videos following the break — it is very tempting to try recreating something similar!

The Ottoman Empire

Remember the good old days in the 60’s and 70’s when stereos were built right into the furniture? No? Well, that’s where the inspiration for this project comes from. Introducing the Ottoman Empire — a pun so bad we’re not even going to repeat it here.

[Alec] was inspired by Blaupunkt, which is a German manufacturer of electronics who used to make a line of very nice cabinet stereos (examples) which blended furniture and electronics quite exquisitely.

He had recently finished off a rather cool 8-track data backup system, and was left with a spare BSR record player — or as he likes to call it, the “Ford Pinto of record players.” He decided to turn it into something useful by integrating it into a Naugahyde Ottoman that he picked up from a local vintage store. The problem with old furniture like that? No structural elements — it was actually just packed full of shredded wood! He cleaned it all out though and then proceeded to make his own wooden frame to support the BSR — he’s done a great job modifying it to fit, and even hiding all the electronics to make it very presentable.

Now all he needs to do is add a pressure switch in the top so when he kicks back to relax it starts playing some Chopin.

Musician On A Budget MIDI Bass Pedals

February 3, 2014 by James Hobson 5 Comments

Organ pedal boards have been around forever — they’re an easy way to multitask while playing the piano, organ, or even the guitar. [Ville] plays the electric guitar and wanted to give bass pedals a shot — the only problem is, the commercial versions are pretty pricey. So he decided to make his own temporary solution using an old MIDI keyboard he had lying around.

The beauty of this hack is it’s completely non-destructive — although you might find you like it so much you won’t want to take it apart! [Ville] started by marking out spacer keys using green cardboard. He then grouped together other sets of keys using tape and polystyrene sheets, which he recycled from a plastic waste bin. He then marked off each set of keys with the range of notes to program into the MIDI receiver — on a 49 key keyboard you get just a bit more than an octave of bass pedal keys! It’ll certainly do until you get your hands on a proper organ pedal unit.

From there it was just a matter of re-mapping the keys on the software end of things, and disabling the other unused keys. He offers a few different methods of doing this, including using VST plugins, and Pure Data — to which he’s provided a patch he made to simplify the process.

To see it in action, stick around after the break and hear [Ville] play One Hour Backwards on electric guitar.

Pan Flute Hero

panflutehero

The latest creation in the never-ending collection of “____ Hero” instruments is this Raspi-infused pan flute, built by [Sven Andersson] and his team at the 2013 WOW Hackathon. The flute itself consists of varying lengths of bamboo from a local flower shop, cut short enough to be hand-held while still hiding the Pi from the front side. In the spirit of other ‘Hero’ instruments, the pan flute has no real musical functionality. Each pipe houses what appears to be an electret microphone breakout board, which they kept in place by sealing off the end of the pipe with glue.

The sensors connect to the GPIO connector on the Raspi, which communicates to a local TCP/IP server the team ran as a controller hub. The game is also their original creation, written entirely in LUA. They turned to Spotify to find suitable material for the player to experience, creating playlists with actual pan flute songs and using the libspotify SDK to access the music. You can see the end result of the project in a short demo video below.

The 8 Bit Harmonica Blows In From Japan

8bit-harmonica

From [Basami Sentaku] in Japan comes this 8bit harmonica. [Basami] must remember those golden days of playing Famicom (or Nintendo Entertainment System for non-Japanese players). As the systems aged, the contacts would spread. In the case of the NES, this would often mean the infamous blinking red power light. The solution for millions of players was simple. Take the cartridge out, blow on it, say a few incantations, and try again. In retrospect, blowing on the cartridges probably did more harm than good, but it seemed like a good idea at the time. We’d always assumed that the Famicom, being a top loading design, was immune from the issues that plagued the horizontal slot on the NES. Either [Basami] spent some time overseas, or he too took to tooting his own cartridge.

Blowing into cartridges has inspired a few crafty souls to stuff real harmonicas into cartridge cases. [Basami] took a more electronic route. A row of 8 microphones picks up the players breath sound. Each microphone is used to trigger a specific note. The katakana in the video shows the traditional Solfège musical scale: do, re, mi, fa, so, la ti, do. A microcontroller monitors the signal from each microphone and determines which one is being triggered. The actual sound is created by a Yamaha YMZ294. The ‘294 is an 18 pin variant of the venerable General Instrument AY-3-8910, a chip long associated with video game music and sound effects. While we’re not convinced that the rendition of Super Mario Bros’ water theme played in the video wasn’t pre-recorded, we are reasonably sure that the hardware is capable of doing everything the video shows.

3D Printed Guitar

January 25, 2014 by Marsh 18 Comments

We’re not sure how we missed this one, but it definitely deserves a look. Professor of Mechtronics [Olaf Diegel’s] 3D printer must go to 12, because he’s printed these incredible electric guitar bodies. You probably won’t be making your own on your filament printer, however, because [Diegel] uses SLS (Selective Laser Sintering) to create the body out of nylon, then he dyes the resulting piece in a two-step process. You can read more about the construction specifics on his website.

And, they’re more than just eye-candy: the guitars sound brilliantly metallic. There are more than enough pictures and videos to keep you occupied on the site, where you can sift through all eight designs to your heart’s content. You’ll want to keep reading for a couple of videos embedded after the break, which feature some demonstrations of the guitar and comparisons to traditional electric guitars, as well as a brief history of its construction and build process.

All-Terrain RC Car Has More Torque Than Your Grandpa’s Wheelchair

[Charles] and his brother have been members of their school’s FIRST robotics team for many years, and using some of the knowledge they acquired during it, they have put together this awesome all-terrain, super over-powered, RC car — and soon to be robot.

It’s built like a tank using 1″ square steel tubing and custom corner brackets made of 1/8″ thick steel. Heavy duty U-bolts hold the over-sized 5/8″ axles, and everything is driven using #35 roller chain. A large 12V sealed lead acid battery powers two CIMs (FIRST Robotics motor) with the AndyMark CIMple gearbox — these give the car tons of torque, and it can even do wheelies!

The really cool part of this project is the method of remote control. He’s using a regular old Xbox controller that an Arduino Uno listens to through a USB host shield and the original Xbox USB receiver. Simple, but totally effective.

The project is not yet complete, and he’s planning on fully equipping it with lights, a larger battery, a roll-cage, a camera system, and some kind of manipulator tool. Check out the test drive video after the break!
