Re-live 1978 in all its glory with the [Roth] Scream Box

March 25, 2012 By Leave a Comment

roth-scream-box

We never imagined that [David Lee Roth] would mesh well with an Arduino, that is until Flickr user [tgtsfkncld] showed off his [Roth] Scream Box a few days ago.

The unassuming box resembles sort of a nondescript “Easy Button”, but its payload is far more entertaining than whatever Staples could have possibly recorded for their device. Once the Scream Box is powered on, each press of the button rewards the user with a short sound clip of [Roth] singing the lyrics from [Van Halen’s] “Runnin’ With the Devil”.

[tgtsfkncld] took snippets of the isolated vocal track from the song, playing them back using an Arduino along with an Adafruit Wave Shield. The circuitry behind the device is not overly complicated, though the final result is great. With the wide array of isolated vocals floating around online, it would be very easy to create one for your favorite band/singer as well.

Isomorphic piano keyboard is button madness

March 19, 2012 By Leave a Comment

[nikescar] sent in a link to a huge isomorphic MIDI keyboard. We might have missed it the first time around, but that doesn’t diminish such a great looking project.

According to the project page, this humongous keyboard is the work people at Louisville Soundbuilders’ efforts to clone the AXiS-64 MIDI controller. Instead of looking like a ‘normal’ piano keyboard, this isomorphic keyboard puts notes in a hexagonal pattern. This keyboard layout is very useful – fingerings for chords are the same across all keys – but these keyboard layouts are fairly rare and MIDI controllers are expensive as a result.

To make the keyboard in the video velocity sensitive, there are two layers of PCBs. The top layer uses Cherry key switches, while the bottom PCB is an array of tact switches. Measuring the time between the top and bottom key presses gives the on board microcontroller velocity information that is converted to MIDI notes. This setup has a few downsides, namely the huge amount of switches, components, and pins needed for two keyboard matrices.

The project page hasn’t been updated for a few months, so we’re pretty curious about the current status of this build. If any of the Louisville Soundbuilders have an update on this project, send it on in.

Gamelatron, a fully robotic indonesian Gamelan orchestra.

March 15, 2012 By Leave a Comment

Last summer we got to have a little chat with [Aaron Taylor] about his automated Gamelan orchestra, Gamelatron. The robotic orchestra features a large collection of Indonesian gongs,  metallophones, xylophones and cymbals actuated using simple pull solenoids attached to mallets.  Gamelatron’s custom controller activates the various 24V solenoids using MIDI,  the whole thing is essentially a gigantic MIDI instrument that can be played by whatever sequencing device you so please.

[Aaron] has a variety of ways to pump MIDI into the controller including the “Padma Bhuwana”, a wooden box with 16 arcade buttons wired to an Arduino. The Arduino can either activate sequences on a computer running Ableton live or the MIDI sequence can be pumped directly out of the Arduino for a computer free interactive installation. [Aaron] also plugs his Akai MPD32 to the computer for live shows or he can just let the laptop do all the work for non-interactive installations.

The really interesting thing about having 170 or so simply actuated instruments is the ability to spread them out and fill every facet of a space. A great example of this was the Temple of Transition at Burning man 2011 where the gongs and what not else would span multiple floors. Here is a recent Wired magazine video published where [Aaron] gives a quick overview of the setup, or if you are too impatient for the ads check out a few videos of Gamelatron in at burning man and PEX summer festival after the jump. We also included [Aaron]’s kickstarter video which has a few more details on the setup (as well as irrelevant stuff about the kickstarter project that has since expired). With all the crazy midi instrument hacks we get around here it is not stretch of the imagination to see this has lots of interactive potential.

A simple touch interface for Music Player Daemon and more

March 15, 2012 By Leave a Comment

mpd-controller

[Andrew] recently got the authorization to install Linux on his work PC, and he was looking for a way to control his music without relying on keyboard shortcuts to do so. Additionally, he wanted an unmistakable visual cue when he received messages in Pidgin, so he decided to build an external input/notification box.

The control box, quite literally, is a cardboard box in which [Andrew] crammed some components he got way back when from the crew at Seeed Studio. A Seeeduino serves as the brains of his control panel, interfacing with his PC over USB. He uses a set of 4 touch sensors and a potentiometer to control the MPD, allowing him to easily switch tracks, pause his music, control the volume, and lock his computer with a simple touch. A side-mounted RGB LED lights green to show that the system has received his commands successfully, pulsing a bright blue whenever a message arrives via Pidgin.

While the case isn’t exactly pretty, it is small, recycled, and takes up very little desk space. [Andrew] says that it works great, and he has made his code available on github if anyone is interested in using it.

Antique phone provides a soundtrack perfect for restoring old cars

March 5, 2012 By Leave a Comment

crank-phone-music

[Simon] is in the middle of restoring/building himself an Austin 7 Special out in his garage, and like most tinkerers, found that music helps to move the process along. He happened to have an old Bakelite generator phone out in the garage as well, and figured that he might as well have it do something other than simply hang on the wall.

Playing music from the 1930 seemed like a fitting enough task, so he picked up an Adafruit Waveshield and spent some time wiring it up to the old telephone. His new radio works simply enough, piping .wav files through the handset, provided someone has cranked the phone’s generator recently.

While cranking the generator is required to play music, the Arduino is actually powered off a pair of AA batteries. The cranking is all cosmetic, but he did program the Arduino to slow the music down every once in awhile, requiring that the generator be turned to get things back up to speed.

It really is a neat way to repurpose the old phone, and we like the fact that [Simon] did not gut it to put this project together.

Quadrotor squadron plays the [James Bond] theme song in preparation for world domination

March 4, 2012 By Leave a Comment

quadrotor-james-bond-theme

If you weren’t already a big fan of quadrotors by this point, we’re pretty sure the video below will get you on the bandwagon in no time flat.

The video was debuted this past week at the TED2012 conference, giving [Daniel Mellinger, Alex Kushleyev, and Vijay Kumar] from the University of Pennsylvania GRASP Lab, a chance to show off their amazing robotics work. The team used a set of autonomous quadrotors to play the [James Bond] theme, complete with keyboard, drums, cymbals, guitar, and maracas.

The coordination of the robots undoubtedly took an incredible amount of time to orchestrate, but after watching the video we think it is well worth the effort. Now of course you can’t simply input a piece of sheet music into the quadrotor control system and expect them to play it, but we imagine that time will arrive before you know it!

Continue reading to see the [James Bond] theme song in full, and be sure to swing by the U Penn site to read more about the project.

Thanks to everyone who sent this one in!
