Guitar Teaches You To Play Using LEDs

April 19, 2011 by 38 Comments

guitarduino

[Andrew] is an electrical engineering student at UIC, and decided that he would build a MIDI guitar for his senior design project. After tinkering for awhile, things were not looking good, and the MIDI guitar idea was scrapped. With his deadline creeping up, he came up with a new idea, the Guitarduino. His new project is a guitar that teaches you how to play chords and scales by showing you the proper notes to play via LEDs embedded in the guitar’s neck.

He removed the neck, and carefully drilled the holes that would eventually house his 130+ LEDs. The LEDs were wired to his Arduino via some multiplexing circuitry that resides on the back of the guitar’s body. The Arduino was mounted on the front of the guitar along with a shield used for communicating with his LED array. He built another shield that serves as the LCD display as well as the input board for his guitar.

The final result of all his work is fantastic. The user simply needs to dial in the chord or scale that he wants to learn, and the guitar lights up, showing the proper finger positions on the fretboard. We could see this coming in quite handy for anyone just starting to learn how to play.

Check out the video below to see a demonstration and walkthrough [Andrew] put together highlighting his guitar’s features.

Feel Like We Do With A Bass Guitar Talk Box

April 15, 2011 by 9 Comments

Hacker [Dino Segovis] wrote in to share the latest hack from his HackAWeek series, and this time around he has constructed a talk box for his bass guitar. Providing you are old enough, you probably remember when the talk box made its way into mainstream music, on the “Frampton Comes Alive” album.

The concept of a talk box is pretty simple. A small speaker is built into a sealed enclosure, which carries the sound from the musician’s guitar to his mouth via a plastic tube. The tube is placed in the musician’s mouth, near the microphone. When his mouth is moved, the sound from the guitar is modified and reflected into the microphone.

[Dino] built a similar system using his bass guitar and an amplifier hacked together from an old tape deck. He initially ran into problems with the sound not making it all the way up the tube due to the bass’ low frequency. He had an ‘Aha!’ moment and mounted the speaker on the mic rather than down on the floor, which seems to have fixed the issue.

Be sure to check out the video below to see his talk box in action.

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.

Printing Your Own Guitar Parts

February 16, 2011 by 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.

LEGO Wah-wah Pedal

January 20, 2011 by 9 Comments

Here’s a guitar wah-wah pedal that [Christian Munk] built. Inside you’ll find a circuit board that he etched and populated based on this design but he chose to build the housing out of LEGO. The video after the break gives you an idea of what it sounds like, but for those who’ve stepped on a LEGO piece with bare feet, his pedal pounding might make you cringe!

To manipulate the sound the pedal rocks forward and backward on a center pivot shown above as a grey “nut” sticking out the side of the frame. Inside there’s a system of LEGO gears that turn a trimpot to alter the sound. This might go along nicely with that guitar amp you hacked together.

Guitar Tube-amp From Junk Hi-fi

January 20, 2011 by 21 Comments

[Tristan Chambers] picked up an old speaker box some friends acquired at a yard sale. It didn’t have any inputs, and there weren’t any tuning knobs like a radio would have, so it’s a mystery what this was originally used for. [Tristan] traced out the circuit and figured out where he could input audio signals which allowed him to hook up an iPod, but it was mono and not very loud. He ended building his own vacuum tube preamp from a schematic he found on the Internet so that he could use it with an electric guitar. As the video after the break shows, the box not only puts out some pretty good sound but it’s nice and loud too.

Building A Germanium Fuzz Face Guitar Pedal

December 27, 2010 by 24 Comments

Rock in the new year with a guitar pedal you built yourself. [Doug Kovach] took the time to share his project with us in the video after the break. He starts with a bit of history of the artists that have used fuzz pedals similar to this one. It seems great guitarists have been hacking since way back. [Doug’s] rendition uses the warm sounds of germanium transistors in a design that produces professional results. But if you need something a little bit less serious try the stomp-box.
