MIDI Controller Fit For An Arcade

February 23, 2011 by Mike Nathan 6 Comments

MIDI controllers can be relatively expensive depending on feature sets and requirements, so Instructables user [fraganator] went about building one on his own for just under $100. He originally wanted to replicate a commercially available MIDI controller, which used arcade buttons in lieu of the more common rubberized buttons, since they are large and have a better feel when pressed. Once he drew up plans for his MIDI clone, he realized he wanted more features in his controller than were available in the commercial version, so he started revising.

His final plan included three rows of four arcade buttons as well as four rotary and two sliding potentiometers. All of the components were mounted in a small keyboard enclosure, then wired to an Arduino clone, which manages all of the controller’s functions. The controller is connected to a PC via USB and can perform any number of operations once the buttons are mapped in MIDI-compatible software.

There are no videos of the controller in action just yet, though [fraganator] says one is forthcoming.

NES Paul Game Controller

[NeoTechni] wrote in to share the new game peripheral she built, dubbed the NES Paul. The ultimate goal of the project was to build a NES-styled controller for an upcoming game she is working on, tentatively titled 8-bit Hero. The guitar is constructed primarily from wood, as well as some scrounged bits she had around the house. An Xbox 360 controller was dismantled and wired to provide input for the guitar’s buttons and D-Pad. Even the Xbox controller’s rumble packs were used in order to provide visual feedback of missed notes via LED tuning pegs on the guitar’s headstock.

The writeup is broken into several pieces as it was put together in a handful of Google Buzz posts, but it is still relatively easy to follow. We can’t wait to see how the project comes together once the game portion has been completed.

Classical’s Greatest Hits On Hardware’s Greatest Flops

February 17, 2011 by Mike Szczys 19 Comments

We get a lot of tips about old hardware playing recognizable tunes. But once in a while one of these projects goes above and beyond the others and this is a shining example of great hardware music. [FunToTheHead] put together a music video (embedded after the break) that shows his custom MIDI device playing Bach’s Toccata in d minor. He left some comments that clue us into the way he did it. Most obviously, he’s using the stepper motors from four floppy drives to create precisely pitched sounds. Internally, a PIC 18F14K50 acts as a MIDI-over-USB device, taking commands for all 128 MIDI notes as well as the pitch bends associated with them. The first four channels are played directly on each drive and the other twelve are triaged among the hardware by the microprocessor. But for the results heard in the video you’ll need to code your MIDI files by hand.

Bonus points to the video editor for the Phantom’s floppy-laden appearance in the video… it’s good to laugh!

Punch Tape Musical Synth

synthanola

[Jeri Ellsworth] sent over a 555 design contest entry that struck her as particularly interesting. The Synthanola is a three-channel music synthesizer that accepts input from an old Heathkit paper tape reader. While this hack might seem overly retro, it’s actually an extremely appropriate use of technology, as the Heathkit H-10 and the 555 timer were both popular tech in the 70’s. This retro-focused synth uses fourteen 555 timers, twelve of which are dedicated to synthesizing audio. If this entry does not win the contest, it certainly must be a strong contender for most 555 timers used.

[Thrashbarg] gives a detailed explanation of the logic used to drive the music playback from the punch tape, as well as full circuit diagrams for his entry. So far he has encoded MP3s of Bach’s Invention and Fugue in D Minor to tape, with hopefully more to come. In order to truly appreciate his efforts, the Synthanola should be seen as well as heard. Stick around for a pair of videos of the synth in action.

If you’re interested in seeing more 555 contest entries, be sure to check out some of our previously featured projects.

Printing Your Own Guitar Parts

February 16, 2011 by Mike Szczys 20 Comments

The white parts that make up the body contours of this guitar have been 3D printed to meet [Bård S D’s] personal specifications. He started designing the pieces last year to add to his Zoybar guitar. Each of the three parts has its own function. The tail piece serves as a floor stand, as well as a hook for hanging the instrument upside down. The wide piece at the top gives the player a place to rest the forearm, and the piece at the bottom serves as a cradle to place on your leg, and contains the jack for the guitar’s pickup. You can see him playing the instrument in the video after the break.

We looked for more information on the Zoybar system but it’s a bit hard to get the facts from that website. We know that the 6-string kit comes standard without frets, and it’ll cost you a pretty penny at around $700. But if it performs as a quality instrument the price isn’t too far out of line.

IR-controlled Musical Alarm Clock

February 15, 2011 by Mike Nathan 11 Comments

Forum user [Frank] shared with us his recent project, a musical alarm clock. More than just a simple alarm clock, his creation allows the user to load music onto a micro SD card, has alarm settings for each day of the week, and best of all, can be controlled using an IR remote. He uses a Teensy++ to control most of the clock’s functions including the display, delegating the time keeping to a DS1307 real-time clock. All of the audio playback is handled by a separate music decoder mounted on a breakout board.

His Instructables writeup is extremely detailed, with tons of annotations, pictures, diagrams, and source code available. He walks through each step in detail, making this a great learning guide for others looking to start in on AVR programming.

His final presentation is a great lesson in recycling, though unfortunately a bit lackluster, as the clock is packaged in an old SparkFun cardboard box. He does mention that there were some time constraints towards the end, which may explain this choice – it would be nice to see a revised version of this clock packaged in a nice plexi case.

Valentine’s Day Love Song Machine

tellart_bell_ensemble

Just in time for Valentine’s day, [Adam Meyer] and the folks over at tellart.com have put together a little project they call the “Love Song Machine“. Using a web-based form, anyone can submit a song, which will then be played on a system of bells that they have set up in their office. You can choose from several pre-defined love songs, or you can create your own unique arrangement with which to serenade them. Once you are ready to go, your song will be queued up, and you can watch a video of your creation as it is being played.

The system is comprised of 8 solenoid-actuated bells which are all controlled by the Arduino they have hooked up to their web server. It’s a pretty fun idea, and there are sure to be plenty of people submitting songs, so get yours in before things get too busy!

Keep reading to see a video preview of their system in action.
