Lego Ev3 Guitar

You can play simple songs like Jingle Bells, Smoke on the Water, and a Blues bass line with it. Demonstrated in the following video.

The guitar is built using only Lego parts. You need a Lego EV3 Ultrasonic distance sensor (part id 95652) and a Lego Mindstorms EV3 Brick (part id 95646c01).

When you press a button, the speaker will play a sound. The buttons are programmed differently for each EV3 program. Here are the button assignments:

Both The Lego Guitar As Well As The Editing Are Top Tier

The fretboard contains 12 colored markings. Each mark represents a semitone. 12 semitones makes the fretboard span over one octave. The frets are numbered 0-11 as in real guitars, where fret 0 is an open string and frets 3, 5 and 7 are highlighted.

The Lego guitar is quite reliable, but you cannot play fast melodies with it. It will produce a wrong note if you move the slider too quickly and press a button. For example the walking blues bass line (demo video) is very close to being too fast. It required several attempts from me to play it without errors.

To upload EV3 programs to the guitar, you can use USB, Bluetooth or Wi-Fi. More information in this manual, page 18. You also need a software called LEGO Mindstorms EV3 Home Edition. With that software you can upload programs to the EV3 Brick, and also edit the programs to change tuning or whatever.

The rock and bass guitar programs use sound samples. The samples are inside the EV3 programs, ready to go. In case you need the samples for your own projects, you can download the wav files in a zip packet here. The origin of the samples is from two sources. The rock guitar samples were taken from NXTPrograms Lego guitar, only edited to sustain longer. The bass guitar samples were generated with FL Studio using a free plugin called Strat-A-Various, with preset Bass guitar.

For the cable there are several options. For example, you can use a 20 cm NXT cable 55804. Or you can order a more thin and flexible cable from mindsensors.com.

The sliding plate size and position are important. The plate is carefully chosen to be a Lego Plate 4×6 3032. Larger plate will make the ultrasonic sensor lose accuracy in close distance and smaller plate makes it lose accuracy in large distance. The position of the plate is in the middle of the fretboard, while the ultrasonic sensor is 0.5 studs offside. If you make any changes to the guitar, you may need to change the sliding plate. set comes with 17 models you can build, program and play with. Yes, I know that the official models are just 5, but there are also 12 bonus models developed by the LEGO MINDSTORMS Experts Panel. I am one of 12 people in the Panel, and the bonus model I made for you is the EL3CTRIC GUITAR, a LEGO guitar that you can play like a real one! So you can make music with LEGO!

You can find all the bonus models in the third tab of the EV3 Software Lobby named “More Robots”. Click on the image of the model, and you will see the building instructions and the program to make it work. You can download the complete .EV3 project by clicking the button below.

The idea of a working LEGO guitar is not completely new. Dave Parker published and demonstrated the NXT version 1 and NXT version 2 on his website NXTprograms. I improved the design to make the LEGO guitar looke like a real Fender® Stratocaster®, and adding a tremolo lever.

My brother Alessandro is a professional guitarist. Since the first prototypes of my LEGO guitar, we wanted to make a real instrument out of it, but the sound quality of the EV3 brick made it sound just like “a squealing cat whose tail has been trapped into a door”. I never found the time to make it sound just like I wanted.

The cool thing about open source projects like this, is having other people improve the initial idea. The Youtube user Dark Avenger has made a custom MIDI adapter for the LEGO guitar, to make it play beautiful and realistic sounds via a synthesizer. He used Arduino and a Bluetooth receiver. The EV3 sends Bluetooth messages to Arduino that implements a MIDI interface to the synthesizer. If you can understand Russian, you can enjoy the first part of the video below, otherwise, you can just skip to about 10 minutes, to hear the guitar solos and power chords.

While I can play the piano, I can’t play the guitar. But I really enjoy posing to make cool photos of my creations! I was asked by the LEGO Group to make a very cool photo for the LEGO Club Magazine. So I called my friend photographer Francesco Rossi for help,  and we came up with this photo. To make it, I had to jump several times, almost risking to destroy my poor knees. I’m not a real rockstar, and unfortunately… the photo never made it to the magazine, because it seems that my face is too scary for kids.

Regarding the photos – they are super cool, but the Club team have asked if you have other images than the two you send us? Maybe some where you facial expression looks less scary (it’s kids and for the German market, they are a bit more conservative than we are).

Spike Prime Guitar

The LEGO guitar was chosen by the LEGO MINDSTORMS team as a gift for the LEGO Group owner‘s 40th anniversary working in the LEGO Group. I wonder if he ever played it… LEGO MINDSTORMS Education designer Master Lee Magpili played it for sure instead!
