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

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.

Recordable SNES Belt Buckle

recordable_snes_controller

[Andrew] recently offered to help out a friend who was looking to get her husband a SNES controller belt buckle. Rather than simply slap one together, he decided that it would be far cooler if the belt buckle played audio as well. He gutted a broken SNES controller, removing most everything inside, leaving just the buttons and a few wires.

To allow for the belt buckle to record sounds, he pulled apart a recordable balloon that would play a 10-second audio clip when shaken. He moved around a few wires, allowing for the audio board to be triggered by a button press rather than motion. Once that was done, he went about fitting it into the SNES controller, drilling speaker and microphone holes in the process. With the electronics components all set, he reassembled the controller shell and mounted it to an old belt buckle he had sitting around.

The final product looks extremely fun, and would make any die hard Nintendo fan’s day.
